Pitfalls and Traps in the Surgical Evaluation of Patients with Irritable Bowel Syndrome (IBS)

Irritable bowel syndrome (IBS) is a complex disorder involving a variety of severe life-altering symptoms and yet-to-be-discovered biologic mechanisms. Patients with IBS are often referred to gastroenterologists who initiate a work-up to rule several potential confounding disease processes. This work-up often involves a consult with a general and/or vascular surgeon to determine if their IBS-like symptoms have an anatomic or surgical etiology. Potential concurrent problems may include the discovery of points or angulations at which gastrointestinal flow is impaired, median arcuate ligament syndrome/angulation, superior mesenteric syndrome/compression, the incidental finding of intestinal malrotation, and others. Once these diagnoses are entertained and/or documented in a patient's chart, "anchoring" on the diagnosis can lead to the belief that their IBS-like symptoms are due to a well-defined, operatively treatable anatomic condition.

In this piece, we will breakdown the potential pitfalls in communicating, advising, and caring for patients with IBS-like symptoms presenting for surgical consultation.

Discussion points are offered with the goal of avoiding unnecessary operations even when faced with compelling anatomic evidence, a highly motivated patient, and a desperate and persuasive family.

Patients suffering from IBS presenting for surgical consultation with a defined anastomotic abnormality that may or may not be related to their symptoms represent a major challenge for surgeons. A multidisciplinary team approach can be useful to avoid unindicated surgery in these patients.
