  • Cyst Fluid Glucose is Rapidly Feasible and Accurate in Diagnosing Mucinous Pancreatic Cysts AMERICAN JOURNAL OF GASTROENTEROLOGY Zikos, T., Pham, K., Bowen, R., Chen, A. M., Banerjee, S., Friedland, S., Dua, M. M., Norton, J. A., Poultsides, G. A., Visser, B. C., Park, W. G. 2015; 110 (6): 909-914

    Abstract

    Better diagnostic tools are needed to differentiate pancreatic cyst subtypes. A previous metabolomic study showed cyst fluid glucose as a potential marker to differentiate mucinous from non-mucinous pancreatic cysts. This study seeks to validate these earlier findings using a standard laboratory glucose assay, a glucometer, and a glucose reagent strip.Using an IRB-approved prospectively collected bio-repository, 65 pancreatic cyst fluid samples (42 mucinous and 23 non-mucinous) with histological correlation were analyzed.Median laboratory glucose, glucometer glucose, and percent reagent strip positive were lower in mucinous vs. non-mucinous cysts (P<0.0001 for all comparisons). Laboratory glucose<50?mg/dl had a sensitivity of 95% and a specificity of 57% (LR+ 2.19, LR- 0.08). Glucometer glucose<50?mg/dl had a sensitivity of 88% and a specificity of 78% (LR+ 4.05, LR- 0.15). Reagent strip glucose had a sensitivity of 81% and a specificity of 74% (LR+ 3.10, LR- 0.26). CEA had a sensitivity of 77% and a specificity of 83% (LR+ 4.67, LR- 0.27). The combination of having either a glucometer glucose<50?mg/dl or a CEA level>192 had a sensitivity of 100% but a low specificity of 33% (LR+ 1.50, LR- 0.00).Glucose, whether measured by a laboratory assay, a glucometer, or a reagent strip, is significantly lower in mucinous cysts compared with non-mucinous pancreatic cysts.

  • Predictive Factors for Surgery Among Patients with Pancreatic Cysts in the Absence of High-Risk Features for Malignancy JOURNAL OF GASTROINTESTINAL SURGERY Quan, S. Y., Visser, B. C., Poultsides, G. A., Norton, J. A., Chen, A. M., Banerjee, S., Friedland, S., Park, W. G. 2015; 19 (6): 1101-1105

    Abstract

    Without a reliable biopsy technique for pancreatic cysts, consensus-based guidelines are used to guide surgical utilization. The primary objective of this study was to characterize the proportion of operations performed outside of these guidelines.A 5-year retrospective review between July 1, 2007, and June 30, 2012, was performed of consecutive patients seen at a single tertiary medical center for a pancreatic cyst. Manual chart review for relevant clinical variables and cyst characteristics was performed.During this period, 148 patients underwent surgery, and of these, 23 (16 %) patients had no high-risk criteria by the 2006 Sendai criteria. None of these harbored high-grade dysplastic or cancerous lesions. A high cyst carcinoembryonic antigen (CEA) level (35 %), patient anxiety (26 %), and physician concern (22 %) were explicit reasons to proceed to surgery. An elevated cyst CEA level >192 ng/ml was the most significant predictor (OR 5.14 (95 % confidence interval (CI) 1.47-18.0) for surgery without high-risk criteria.A high cyst CEA level was significantly associated with the decision to operate outside of consensus-based guidelines. The misuse of cyst CEA in the management of pancreatic cysts negatively impacts patient anxiety, increases physician uncertainty, and leads to surgery with minimal benefit.

  • Radiation exposure to patients during ERCP is significantly higher with low-volume endoscopists. Gastrointestinal endoscopy Liao, C., Thosani, N., Kothari, S., Friedland, S., Chen, A., Banerjee, S. 2015; 81 (2): 391-8 e1

    Abstract

    Patients are exposed to radiation during ERCP, and this may increase their lifetime risk of the development of cancer and other deleterious radiation effects.To evaluate the association between the endoscopist's ERCP volume and the patient radiation dose during ERCP.Single-center, retrospective study.Tertiary referral center.A total of 197 patients undergoing 331 ERCPs.Patient radiation exposure parameters including fluoroscopy time, total radiation dose, dose area product, and effective dose for all ERCPs performed at our academic medical center by 2 high-volume endoscopists (HVEs) (?200 ERCPs/year) and 7 low-volume endoscopists (LVEs). Radiation exposure for each ERCP was adjusted against a validated procedure complexity scale and the Stanford Fluoroscopy Complexity Score, which was created based on the numbers of interventions that would mandate additional radiation exposure.ERCPs performed by LVEs were associated with a significantly higher median total radiation dose (98.30 mGy vs 74.13 mGy), dose area product (13.98 Gy-cm(2) vs 8.8 Gy-cm(2)), and effective dose (3.63 mSv vs 2.28 mSv), despite lower median Stanford Fluoroscopy Complexity Scores (3.0 vs 6.0) compared with HVEs. No significant difference was noted in median fluoroscopy time (4.0 minutes vs 3.30 minutes) between LVEs and HVEs.Retrospective, single-center study at a tertiary referral center.ERCPs performed by LVEs are associated with significantly higher radiation exposure to patients compared with those performed by HVEs despite the fact that procedures performed by HVEs are of greater complexity.

  • Short turn radius colonoscope in an anatomical model: Retroflexed withdrawal and detection of hidden polyps WORLD JOURNAL OF GASTROENTEROLOGY Mcgill, S. K., Kothari, S., Friedland, S., Chen, A., Park, W. G., Banerjee, S. 2015; 21 (2): 593-599

    Abstract

    To evaluate the new RetroView? colonoscope and compare its ability to detect simulated polyps "hidden" behind colonic folds with that of a conventional colonoscope, utilizing anatomic colon models.Three anatomic colon models were prepared, with twelve simulated polyps "hidden" behind haustral folds and five placed in easily viewed locations in each model. Five blinded endoscopists examined two colon models in random order with the conventional or RetroView? colonoscope, utilizing standard withdrawal technique. The third colon model was then examined with the RetroView? colonoscope withdrawn initially in retroflexion and then in standard withdrawal. Polyp detection rates during standard and retroflexed withdrawal of the conventional and RetroView? colonoscopes were determined. Polyp detection rates for combined standard and retroflexed withdrawal (combination withdrawal) with the RetroView? colonoscope were also determined.For hidden polyps, retroflexed withdrawal using the RetroView? colonoscope detected more polyps than the conventional colonoscope in standard withdrawal (85% vs 12%, P = 0.0001). For hidden polyps, combination withdrawal with the RetroView? colonoscope detected more polyps than the conventional colonoscope in standard withdrawal (93% vs 12%, P ? 0.0001). The RetroView? colonoscope in "combination withdrawal" was superior to other methods in detecting all (hidden + easily visible) polyps, with successful detection of 80 of 85 polyps (94%) compared to 28 (32%) polyps detected by the conventional colonoscope in standard withdrawal (P < 0.0001) and 67 (79%) polyps detected by the RetroView? colonoscope in retroflexed withdrawal alone (P < 0.01). Continuous withdrawal of the colonoscope through the colon model while retroflexed was achieved by all endoscopists. In a post-test survey, four out of five colonoscopists reported that manipulation of the colonoscope was easy or very easy.In simulated testing, the RetroView? colonoscope increased detection of hidden polyps. Combining standard withdrawal with retroflexed withdrawal may become the new paradigm for "complete screening colonoscopy".

  • Effect of prior biopsy sampling, tattoo placement, and snare sampling on endoscopic resection of large nonpedunculated colorectal lesions GASTROINTESTINAL ENDOSCOPY Kim, H. G., Thosani, N., Banerjee, S., Chen, A., Friedland, S. 2015; 81 (1): 204-213

    Abstract

    Endoscopic manipulations, including biopsy sampling, tattoo application on the lesion itself, and sampling of the lesion with a polypectomy snare, are frequently performed on large nonpedunculated colorectal lesions ? 20 mm (LNCL) before referral for endoscopic resection.To assess the effect of prior manipulations on the technical difficulty and recurrence rates of subsequent endoscopic treatment.Retrospective study.Two referral centers.Patients with LNCL referred for endoscopic resection.Endoscopic resection.En-bloc resection rate, rate of successful complete endoscopic resection without the need for ablation of visible residual, recurrence rate on follow-up, independent predictive factors for en-bloc resection, complete resection without ablation of visible residual, and recurrence.A total of 132 lesions was analyzed: 46 lesions without any prior manipulation, 44 with prior biopsy sampling only, and 42 with prior advanced manipulation including tattoo and/or snare sampling. The en-bloc resection rate was 34.8% for nonmanipulated lesions, 15.9% for lesions with prior biopsy sampling, and 4.8% for lesions with prior advanced manipulation (P = .001). Complete endoscopic resection without the need for ablation of visible residual was performed in 93.5% of nonmanipulated lesions, 68.2% of lesions with prior biopsy sampling, and 50% of lesions with prior advanced manipulation (P < .001). Recurrence rates were 7.7%, 40.7%, and 53.8% in the 3 groups (P = .001). In multivariate analysis, prior biopsy sampling was an independent predictor for inability to perform complete resection without ablation of visible residual (odds ratio .24, P < .05) and for recurrence (odds ratio 11.5, P = .004) compared with nonmanipulated lesions. Prior advanced manipulation was an independent predictor for inability to perform en-bloc resection (odds ratio .024, P = .001), for inability to perform complete resection without ablation of visible residual (odds ratio .081, P < .001), and for recurrence (odds ratio 18.8, P = .001).Retrospective study.Prior biopsy sampling and advanced manipulation have significant deleterious effects on endoscopic treatment of LNCL.

  • Underwater endoscopic mucosal resection for recurrences after previous piecemeal resection of colorectal polyps GASTROINTESTINAL ENDOSCOPY Kim, H. G., Thosani, N., Banerjee, S., Chen, A., Friedland, S. 2014; 80 (6): 1094-1102

    Abstract

    Conventional endoscopic treatment of a recurrent adenoma after piecemeal EMR (PEMR) of a colorectal laterally spreading tumor (LST) is technically difficult with low en bloc resection rates because of the inability to snare fibrotic residual.To assess the feasibility of salvage underwater EMR (UEMR) for the treatment of recurrent adenoma after PEMR of a colorectal LST.Retrospective, cross-sectional study.Single, tertiary-care referral center.Patients who have recurrent adenoma after PEMR of colorectal LST (?2 cm).UEMR versus EMR.En bloc resection rate, endoscopic complete removal rate, recurrence rate on follow-up colonoscopy, adjunctive ablation rate with argon plasma coagulation (APC) during salvage procedure, and independent predictive factors for successful en bloc resection and endoscopic complete removal.Eighty salvage procedures (36 UEMRs vs 44 EMRs) were analyzed. En bloc resection rate (47.2% vs 15.9%, P = .002) and endoscopic complete removal rate (88.9% vs 31.8%, P < .001) were higher in the UEMR group than in the EMR group. APC ablation of visible residual during salvage procedure was lower in UEMR group than EMR group (11.1% vs 65.9%, P < .001). Recurrence rate on follow-up colonoscopy was significantly lower in the UEMR group than the EMR group (10% vs 39.4%, P = .02). UEMR was an independent predictor of successful en bloc resection and endoscopic complete removal.Retrospective, single-center study.UEMR can be a useful and feasible technique as a salvage procedure for recurrent colorectal adenoma after PEMR.

  • Endoscopic Retrograde Cholangiopancreatography for Primary Sclerosing Cholangitis CLINICS IN LIVER DISEASE Thosani, N., Banerjee, S. 2014; 18 (4): 899-?
  • Endoscopic retrograde cholangiopancreatography for primary sclerosing cholangitis. Clinics in liver disease Thosani, N., Banerjee, S. 2014; 18 (4): 899-911

    Abstract

    Although there are no randomized, controlled trials evaluating the efficacy of endoscopic retrograde cholangiography (ERC) in primary sclerosing cholangitis (PSC) patients, substantial indirect evidence supports the effectiveness of ERC in symptomatic PSC patients with a dominant stricture. Currently, cumulative evidence supports the role of ERC with endoscopic dilation with or without additional short-term stent placement for symptomatic PSC patients with a dominant stricture. Differentiating benign dominant strictures from cholangiocarcinoma (CCA) remains difficult; however, newer endoscopic techniques and advanced cytologic techniques are likely to improve sensitivity for the diagnosis of CCA over that achieved by traditional cytology brushing alone.

  • Outcomes of repeat colonoscopy in patients with polyps referred for surgery without biopsy-proven cancer GASTROINTESTINAL ENDOSCOPY Friedland, S., Banerjee, S., Kochar, R., Chen, A., Shelton, A. 2014; 79 (1): 101-107

    Abstract

    Despite advances in endoscopic treatment, many colonic adenomas are still referred for surgical resection. There is a paucity of data on the suitability of these lesions for endoscopic treatment.To analyze the results of routine repeat colonoscopy in patients referred for surgical resection of colon polyps without biopsy-proven cancer.Retrospective review.University hospital.Patients referred to a colorectal surgeon for surgical resection of a polyp without biopsy-proven cancer.Repeat colonoscopy.The rate of successful endoscopic treatment.There were 38 lesions in 36 patients; 71% of the lesions were noncancerous and were successfully treated endoscopically. In 26% of the lesions, previous removal was attempted by the referring physician but was unsuccessful. The adenoma recurrence rate was 50%, but all recurrences were treated endoscopically and none were cancerous. Two patients were admitted for overnight observation. There were no major adverse events.Single center, retrospective.In the absence of biopsy-proven invasive cancer, it is appropriate to reevaluate patients referred for surgical resection by repeat colonoscopy at an expert center.

  • Root Cause Analysis of Gastroduodenal Ulceration After Yttrium-90 Radioembolization CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY Lam, M. G., Banerjee, S., Louie, J. D., Abdelmaksoud, M. H., Iagaru, A. H., Ennen, R. E., Sze, D. Y. 2013; 36 (6): 1536-1547

    Abstract

    INTRODUCTION: A root cause analysis was performed on the occurrence of gastroduodenal ulceration after hepatic radioembolization (RE). We aimed to identify the risk factors in the treated population and to determine the specific mechanism of nontarget RE in individual cases. METHODS: The records of 247 consecutive patients treated with yttrium-90 RE for primary (n = 90) or metastatic (n = 157) liver cancer using either resin (n = 181) or glass (n = 66) microspheres were reviewed. All patients who developed a biopsy-proven microsphere-induced gastroduodenal ulcer were identified. Univariate and multivariate analyses were performed on baseline parameters and procedural data to determine possible risk factors in the total population. Individual cases were analyzed to ascertain the specific cause, including identification of the culprit vessel(s) leading to extrahepatic deposition of the microspheres. RESULTS: Eight patients (3.2 %) developed a gastroduodenal ulcer. Stasis during injection was the strongest independent risk factor (p = 0.004), followed by distal origin of the gastroduodenal artery (p = 0.004), young age (p = 0.040), and proximal injection of the microspheres (p = 0.043). Prolonged administrations, pain during administration, whole liver treatment, and use of resin microspheres also showed interrelated trends in multivariate analysis. Retrospective review of intraprocedural and postprocedural imaging showed a probable or possible culprit vessel, each a tiny complex collateral vessel, in seven patients. CONCLUSION: Proximal administrations and those resulting in stasis of flow presented increased risk for gastroduodenal ulceration. Patients who had undergone bevacizumab therapy were at high risk for developing stasis.

  • Infections of the biliary tract. Gastrointestinal endoscopy clinics of North America Kochar, R., Banerjee, S. 2013; 23 (2): 199-218

    Abstract

    Infection of the biliary tract, or cholangitis, is a potentially life-threatening condition. Bile duct stones are the most common cause of biliary obstruction predisposing to cholangitis. The key components in the pathogenesis of cholangitis are biliary obstruction and biliary infection. Several underlying mechanisms of bactibilia have been proposed. Characteristic clinical features of cholangitis include abdominal pain, fever, and jaundice. A combination of clinical features with laboratory tests and imaging studies are frequently used to diagnose cholangitis. Endoscopic retrograde cholangiopancreatography is the best diagnostic test. Less invasive imaging tests may be performed initially in clinically stable patients with uncertain diagnoses.

    Abstract

    Biliary and pancreatic stents are used in a variety of benign and malignant conditions including strictures and leaks and in the prevention of post-ERCP pancreatitis.Both plastic and metal stents are safe, effective, and easy to use. SEMSs have traditionally been used for inoperable malignant disease. Covered SEMSs are now being evaluated for use in benign disease. Increasing the duration of patency of both plastic and metal stents remains an important area for future research.

  • Endoscopic management of nonlifting colon polyps. Diagnostic and therapeutic endoscopy Friedland, S., Shelton, A., Kothari, S., Kochar, R., Chen, A., Banerjee, S. 2013; 2013: 412936-?

    Abstract

    Background and Study Aims. The nonlifting polyp sign of invasive colon cancer is considered highly sensitive and specific for cancer extending beyond the mid-submucosa. However, prior interventions can cause adenomas to become nonlifting due to fibrosis. It is unclear whether nonlifting adenomas can be successfully treated endoscopically. The aim of this study was to evaluate outcomes in a referral practice incorporating a standardized protocol of attempted endoscopic resection of nonlifting lesions previously treated by biopsy, polypectomy, surgery, or tattoo placement. Patients and Methods. Retrospective review of patients undergoing colonoscopy by one endoscopist at two hospitals found to have nonlifting lesions from prior interventions. Lesions with biopsy proven invasive cancer or definite endoscopic features of invasive cancer were excluded. Lesions ? 8?mm were routinely injected with saline prior to attempted endoscopic resection. Polypectomy was performed using a stiff snare, followed by argon plasma coagulation (APC) if necessary. Results. 26 patients each had a single nonlifting lesion with a history of prior intervention. Endoscopic resection was completed in 25 (96%). 22 required snare resection and APC. 1 patient had invasive cancer and was referred for surgery. The recurrence rate on follow-up colonoscopy was 26%. All of the recurrences were successfully treated endoscopically. There was 1 postprocedure bleed (4%), no perforations, and no other complications. Conclusions. The majority of adenomas that are nonlifting after prior interventions can be treated successfully and safely by a combination of piecemeal polypectomy and ablation. Although recurrence rates are high at 26%, these too can be successfully treated endoscopically.

    Abstract

    The American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee provides reviews of new or emerging endoscopic technologies that have the potential to have an impact on the practice of GI endoscopy. Evidence-based methodology is used, with a MEDLINE literature search to identify pertinent preclinical and clinical studies on the topic and a MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database search to identify the reported complications of a given technology. Both are supplemented by accessing the "related articles" feature of PubMed and by scrutinizing pertinent references cited by the identified studies. Controlled clinical trials are emphasized, but in many cases, data from randomized, controlled trials are lacking. In such cases, large case series, preliminary clinical studies, and expert opinions are used. Technical data are gathered from traditional and Web-based publications, proprietary publications, and informal communications with pertinent vendors. For this review, the MEDLINE database was searched through January 2011 using the keywords "bariatric," "endoscopic," "intragastric balloon," "duodenojejunal bypass sleeve," and "transoral gastroplasty." Reports on Emerging Technologies are drafted by 1 or 2 members of the ASGE Technology Committee, reviewed and edited by the committee as a whole, and approved by the Governing Board of the ASGE. These reports are scientific reviews provided solely for educational and informational purposes. Reports on Emerging Technologies are not rules and should not be construed as establishing a legal standard of care or as encouraging, advocating, requiring, or discouraging any particular treatment or payment for such treatment.

  • Endoscopic mucosal resection with an over-the-counter hyaluronate preparation GASTROINTESTINAL ENDOSCOPY Friedland, S., Kothari, S., Chen, A., Park, W., Banerjee, S. 2012; 75 (5): 1040-1044

    Abstract

    Hyaluronic acid (HA) provides a long-lasting and distinct mucosal elevation for EMR, but expense and inconvenience have limited its adoption.To evaluate the safety and efficacy of an over-the-counter 0.15% HA preparation for EMR.Retrospective study.Veterans Administration Hospital and university hospital.30 patients with a total of 32 colonic lesions and 1 duodenal lesion.EMR by using HA.En bloc resection rate and complications.EMR was successful in all cases. En bloc resection was achieved in 26 of the 28 lesions up to 25 mm in diameter. Two lesions, both with fibrosis from prior attempted resection, had trace residual tissue necessitating cauterization with argon plasma. Five lesions measuring 30 mm to 60 mm all required piecemeal resection. There was one complication, a postpolypectomy bleed.Small number of patients and retrospective design.EMR may be performed safely and effectively by using an inexpensive, over-the-counter 0.15% HA preparation. Further studies are needed to verify the results of this study and to compare the safety and efficacy of this HA preparation with saline solution.

    Abstract

    The American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methodology is used, with a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database search to identify the reported complications of a given technology. Both are supplemented by accessing the "related articles" feature of PubMed and by scrutinizing pertinent references cited by the identified studies. Controlled clinical trials are emphasized, but in many cases, data from randomized, controlled trials are lacking. In such cases, large case series, preliminary clinical studies, and expert opinions are used. Technical data are gathered from traditional and Web-based publications, proprietary publications, and informal communications with pertinent vendors. Technology Status Evaluation Reports are drafted by 1 or 2 members of the ASGE Technology Committee, reviewed and edited by the committee as a whole, and approved by the Governing Board of the ASGE. When financial guidance is indicated, the most recent coding data and list prices at the time of publication are provided. For this review, the MEDLINE database was searched through January 2010 for articles related to endoscopic tattooing by using the Keywords tattooing, colonic, endoscopic, India ink, indocyanine green in different search term combinations. Technology Status Evaluation Reports are scientific reviews provided solely for educational and informational purposes. Technology Status Evaluation Reports are not rules and should not be construed as establishing a legal standard of care or as encouraging, advocating, requiring, or discouraging any particular treatment or payment for such treatment.

  • Screening for Barrett's esophagus in asymptomatic women GASTROINTESTINAL ENDOSCOPY Gerson, L. B., Banerjee, S. 2009; 70 (5): 867-873

    Abstract

    Barrett's esophagus (BE) has been detected in approximately 10% of patients with chronic GERD. Previous studies demonstrated a similar prevalence of BE in asymptomatic adults.To determine the prevalence of BE in asymptomatic women.We invited women scheduled for routine screening colonoscopy (for colorectal cancer) and women undergoing endoscopic examination before bariatric surgery to participate. Patients experiencing heartburn symptoms more than once per month were excluded.Outpatients at Stanford University and Palo Alto VA Health Care System.Biopsies of the esophagogastric junction in the setting of suspected BE, and completion of symptom and health-related quality of life questionnaires to ensure that subjects were asymptomatic.Identification of BE.We detected BE in 8 (6%) of 126 subjects, including 3 (5%) of 61 of the women in the colorectal cancer screening cohort and 5 (8%) of 65 of the women in the pre-bariatric surgery cohort, all of whom had BE measuring 2 cm or less (P = .30). Patients found to have BE were more likely to be older (mean age 60 years vs 49 years, respectively; P = .04), but there was no difference in mean body mass index, ethnicity, or tobacco or alcohol use between patients with and without BE. BE was only present in pre-bariatric surgery subjects younger than the age of 50 and was most common in the 61- to 70-year age cohort in both groups. Erosive esophagitis, microscopic reflux changes, and Helicobacter pylori infection were not more common in the pre-bariatric surgery group.Small number of subjects with BE detected.Short-segment BE was detected in 6% of asymptomatic women undergoing screening endoscopic examinations.

  • Preoperative endoscopic screening for laparoscopic Roux-en-Y gastric bypass has a low yield for anatomic findings OBESITY SURGERY Mong, C., Van Dam, J., Morton, J., Gerson, L., Curet, M., Banerjee, S. 2008; 18 (9): 1067-1073

    Abstract

    Patients undergoing laparoscopic Roux-en-Y bariatric surgery undergo screening esophagoduodenoscopy (EGD) during preoperative evaluation. The hypothesis is to examine the utility of this examination. The purpose of this study was to evaluate the prevalence of clinically significant upper gastrointestinal (UGI) tract findings at screening EGD in patients undergoing laparoscopic Roux-en-Y bariatric surgery. A secondary aim was to determine whether preprocedure symptoms could predict findings at EGD.We evaluated records of patients undergoing EGD prior to bariatric surgery between 2000 and 2005 at the Stanford University Medical Center. Clinical, endoscopic, and pathological data were analyzed. The prevalence of endoscopic findings of clinical significance was determined.Two hundred seventy two complete patient records were identified and included in the study. Of these, 237 (87%) were female and 197 (72%) were Caucasian. The mean age was 43 +/- 9.68 years and mean body mass index was 48 +/- 7.95 kg/m(2). Of the 272 patients, 33 (12%) had EGD findings of clinical significance including erosive esophagitis (3.7%), Barrett's esophagus (3.7%), gastric ulcers (2.9%), erosive gastritis (1.8%), duodenal ulcers (0.7%), and gastric carcinoid (0.3%). No patients had malignancy. Of these 33 patients, 22 (67%) had UGI symptoms.Significant findings at screening EGD were found in 12% of patients. While EGD may be low-yield, the findings could be useful in guiding clinical decision making.

  • Use of flexible endoscopic scissors to cut obstructing suture material in gastric bypass patients OBESITY SURGERY Patel, C., Van Dam, J., Curet, M., Morton, J. M., Banerjee, S. 2008; 18 (3): 336-339

    Abstract

    With the epidemic increase in obesity in the USA and consequent increased demand for bariatric surgery, new complications of the surgery are being described. The most common surgery practiced is the Roux-en-Y gastric bypass (RYGBP). Unraveling of suture material at the gastrojejunal anastomosis may occur, which may be troublesome if nonabsorbable suture is employed. We describe, for the first time, two patients who developed obstructive symptoms as a consequence of food matter/bezoars entrapped within a mesh of unraveled nonabsorbable suture material at their anastomoses. One of these patients also developed ulceration, presumably as a result of pressure necrosis from the entrapped bezoar. We describe a third patient where the placement of nonabsorbable sutures led to obstructive symptoms by limiting distensibility at an otherwise satisfactory anastomosis. We also describe for the first time, the use of a new endoscopic scissors in cutting luminal suture material with subsequent resolution of the clinical problem.

  • Analysis of cystic fibrosis gener product (CFTR) function in patients with pancreas divisum and recurrent acute pancreatitis AMERICAN JOURNAL OF GASTROENTEROLOGY Gelrud, A., SHETH, S., Banerjee, S., Weed, D., Shea, J., Chuttani, R., Howell, D. A., Telford, J. J., Carr-Locke, D. L., Regan, M. M., Ellis, L., Durie, P. R., Freedman, S. D. 2004; 99 (8): 1557-1562

    Abstract

    The mechanism by which pancreas divisum may lead to recurrent episodes of acute pancreatitis in a subset of individuals is unknown. Abnormalities of the cystic fibrosis gene product (CFTR) have been implicated in the genesis of idiopathic chronic pancreatitis. The aim of this study was to determine if CFTR function is abnormal in patients with pancreas divisum and recurrent acute pancreatitis (PD/RAP).A total of 69 healthy control subjects, 12 patients with PD/RAP, 16 obligate heterozygotes with a single CFTR mutation, and 95 patients with cystic fibrosis were enrolled. CFTR function was analyzed by nasal transepithelial potential difference testing in vivo. The outcomes of the PD/RAP patients following endoscopic and surgical treatments were concomitantly analyzed.Direct measurement of CFTR function in nasal epithelium in response to isoproterenol demonstrated that the values for PD/RAP were intermediate between those observed for healthy controls and cystic fibrosis patients. The median value was 13 mV for PD/RAP subjects, which was statistically different from healthy controls (22 mV, p= 0.001) and cystic fibrosis pancreatic sufficient (-1 mV, p < 0.0001) and pancreatic insufficient (-3 mV, p < 0.0001) patients.These results suggest a link between CFTR dysfunction and recurrent acute pancreatitis in patients with pancreas divisum and may explain why a subset of patients with pancreas divisum develops recurrent acute pancreatitis.
