Endoscopists and Surgeons Playing in the Same Team: The Multidisciplinary Approach in Screening and Preoperative Workup

Abstract

In the multidisciplinary approach of a patient seeking surgical help for severe obesity, a multidisciplinary team is often involved and other specialities such as a pulmonologist and a cardiologist are called up when needed. In this row, the interventional radiologist, the gastroenterologist and the endoscopist figure as a second-hand assist. Some advocate endoscopists to be part of the multidisciplinary team already from the onset. Several guidelines define the minimum requirements of preoperative workup, but leave the decision of a preoperative endoscopy and gastrointestinal workup to the surgeon, i.e. only in patients with clinically significant gastrointestinal symptoms. However, obesity is associated with oesophageal motility disturbances and with gastro-oesophageal reflux-promoting circumstances. These conditions are often asymptomatic in the obese preoperatively and may become symptomatic after certain types of surgery. Moreover, when gastro-oesophageal symptoms resolve after an operation, this does not necessarily signify an improvement because the development of Barrett’s epithelium as an adaptation to acid reflux may obscure this premalignant and adverse complication of gastro-oesophageal reflux disease. The fear of missing a cancer is not a real problem in low-incidence areas and as such not a true indication for a preoperative endoscopy but this may be different in Asian countries. The two meta-analyses that investigated changes in the choice of the procedure based on endoscopic findings concluded that routine endoscopy is not indicated and that patient’s symptoms, risk factors and type of procedure planned should be the leading factors, but as stated earlier you can win a lot of haggling. Another controversy is the need of preoperative weight loss, often required by insurance companies, but here surgeons and gastroenterologists should navigate on their personal experience, the type and degree of obese referrals, and the volume of operations already having performed.
