INTRODUCTION: Staple line leaks following laparoscopic sleeve gastrectomy (LSG) are associated with significant morbidity and mortality. Endoluminal techniques, including stent placement and endoluminal vacuum therapy (EVAC), have become viable options to treat these patients without the need for additional surgery. The purpose of this study was to define the conditions where certain endoscopic therapies are most likely to succeed compared to surgery. METHODS: An IRB approved prospectively maintained database was retrospectively reviewed for all patients treated for gastrointestinal leaks from July 2013 to March 2019. All patients who were treated for gastrointestinal leaks following LSG were included. Endpoints include success of leak closure and hospital-related morbidity for the patients treated solely by endoscopic only methods (EP) compared to the additional surgery group (SP). RESULTS: There were 39 patients (33 females; 6 males) with a median age of 45.9 years. The EP group included 23 patients (59%), whereas SP included 16 patients (31%). On average, the SP had longer days from sentinel surgery to our hospital admission (70 vs 41), a higher percentage of previous bariatric surgery prior to sentinel LSG (50% vs 17%), and a higher readmission rates following discharge (50% vs 39%). Total length of stay was also higher in the SP compared to the EP (45.4 vs 11). Using this data, a treatment algorithm was developed to optimally treat future patients who suffer from gastrointestinal leaks following LSG. CONCLUSIONS: Endoscopic therapies, such as EVAC, stent placement, internal drainage, and over-the-scope clips, have a higher chance of success if performed earlier to their sentinel surgery and if patients have had no prior bariatric surgeries. Patients who require additional surgery tend to have longer hospital stays and readmission rates. Using the treatment algorithm provided can help determine when endoscopic therapies are likely to succeed.
