Brooke Gurland, MD, FACS
Clinical Professor, Surgery - General Surgery
Bio Pelvic floor and functional bowel disorders refer to a series of symptoms and anatomic findings that effect men and women of all ages. These may include: constipation, difficult evacuation, fecal incontinence, irritable bowel disorders, diarrhea, pelvic organ prolapse, urinary and sexual dysfunction and pain. Although not life threatening, these disorders can severely affect quality of life and individual performance.
Over the past two decades I have dedicated my career to working with other specialists for comprehensive care for individuals with pelvic floor disorders. In July 2017, I joined The Department of Surgery, Division of Colorectal Surgery at Stanford University as the Medical Director of the Pelvic Health Center. I previously spent the prior decade at Cleveland Clinic running a multidisciplinary clinic and performing over 200 combined procedures in conjunction with colleagues in urology and urogynecology. We developed a robotic surgical approach to woman with vaginal and rectal prolapse and performed many surgeries to repair intestinal and rectal fistula (abnormal communications between the intestine and vagina).
Prior to that I established a Pelvic Floor Center at Maimonides Medical Center received a Jahnigan Career Development Award looking at multicompartment prolapse in elderly women. In addition to performing surgery and teaching throughout my career, I have maintained a commitment to long-term follow up of patients after surgery.
Although my training and focus is around surgical techniques and solutions for anorectal disorders and pelvic health, I believe that prevention, non-surgical alternatives, diet, exercise, and behavior management are vitally important to patient success.
One of my many goals is to educate patients, health care providers, and trainees about pelvic floor disorders.
When I am not at work I enjoy quality time with my three teenagers, dog, friends and I practice yoga.

Mary Hawn, MD, FACS
Emile Holman Professor in Surgery
Current Research and Scholarly Interests My area of research is health services researcher focusing on surgical quality measurement and policy. I have a background and training in epidemiology coupled with my leadership roles in surgical quality measurement. My expertise and extensive experience in evaluation of surgical quality process and outcome linkage has impacted national policy and changed guidelines. We performed a comprehensive evaluation of the Surgical Care Improvement Project (SCIP) implementation using national VA data. Defining robust metrics of surgical quality that are actionable and can lead to sustained improvement in our field are of utmost importance. I also have experience with risk prediction modeling for surgical patients. Our Decision Support for Safer Surgery study developed models of real-time risk prediction for major complications and prospectively validated our models in patients and with expert surgeons. We were able to discern where computational risk prediction has added value and where it falls short. We currently have a national study investigating readmissions following major surgical procedures to identify opportunities for improving care and reducing costs.

Karthikeshwar Kasirajan (Kasi)
Clinical Professor, Surgery - Vascular Surgery
Bio Dr. Kasirajan is a board-certified, fellowship-trained vascular surgeon. Also known as Dr. Kasi, he is a clinical professor of vascular surgery at Stanford University School of Medicine.
Dr. Kasirajan preserves limbs, facilitates access to dialysis, and helps his patients manage conditions such as aneurysms, varicose veins, thoracic outlet syndrome, and deep vein thrombosis. Many of his limb preservation patients smoke, have diabetes, or are experiencing renal failure. Dr. Kasirajan?s experience also centers around the treatment of aneurysms and prevention of strokes.
In all cases, his goal is to provide either noninvasive or minimally invasive management whenever possible. He performs open surgery only when it is the best option. Dr. Kasirajan treats many patients with stents and stent grafts, which can shorten hospital stays and recovery times.
Dr. Kasirajan (Kasi) receives referrals of patients from primary care physicians, nephrologists, podiatrists, cardiologists, woundcare specialists, diabetologists, neurologists, and other specialists. He welcomes referrals as early as possible, ideally before patients become symptomatic. A strong proponent of doing early screening for peripheral artery disease, Dr. Kasirajan advocates for the use of the ankle-brachial index (ABI) in routine physical examinations. When providers detect an imbalance between leg and arm blood pressure, Dr. Kasirajan can help create customized strategies to address the cause before the problem worsens.
In addition to offering excellent vascular care to the community, Dr. Kasirajan joined Stanford to continue pursuing his research interests. He has conducted research into advances in minimally invasive procedures for stroke prevention and for aneurysm management. His research has also focused on how to improve surgery outcomes to help patients suffering from peripheral vascular disease. Dr. Kasirajan has been the investigator in over 40 multicenter studies involving new stent graphs, thrombectomy catheters, and other advances in endovascular technology.
Dr. Kasirajan has made more than 100 presentations worldwide on minimally invasive vascular surgery techniques and preventive care in the vascular patient. He has spoken at multiple conferences including the Society for Vascular Surgery, Peripheral Vascular Society, and the South Asian American Vascular Society. He has earned numerous honors for his academic achievements, including the prestigious Alpha Omega Alpha award for medical student and resident education.
As the author of more than 120 journal articles, Dr. Kasirajan?s work has appeared in the Journal of Vascular Surgery, Endovascular Today, Pharmacogenomics Journal, Catheter Cardiovascular Intervention, and many other publications. He also has authored 20 book chapters in textbooks including Medical Management of the Surgical Patient 5th Edition, Advances in Phlebology and Venus Surgery Volume 1, Current Therapy in Vascular Surgery, Mastery of Surgery, and many more.
