Introduction
It is commonly stated in bariatric surgical forums that leaks following laparoscopic sleeve gastrectomy (LSG) are more difficult to manage than those following laparoscopic roux-en-Y gastric bypass (LRYGB). However, no previous study has provided a thorough comparison of leak management following these two operations.
Methods
Our database was retrospectively reviewed to identify patients with leak following LSG and LRYGB performed between January 2007 and December 2017.
Results
Postoperative leak was diagnosed in 16/2132 (0.75%) LSG and 9/595 (1.5%) LRYGB patients. More of the LRYGB leaks had undergone revisional surgeries (66.7 vs. 6.3%, p < 0.001), and were diagnosed in the index admission (77.8 vs. 18.7%, p = 0.002). The mean time between the bariatric operation and the diagnosis of leak was 6.0 days in LRYGB and 26.2 days in LSG patients (p = 0.097). Approximately two thirds of each group were initially treated with laparoscopic exploration and drainage. Subsequent endoscopy was utilized more commonly in LSG patients (87.5 vs. 22.2%, p < 0.001). Drainage alone (laparoscopic or percutaneous) eventually led to leak resolution in more LRYGB patients (66.7 vs. 18.8%, p = 0.02), while endoscopic intervention led to resolution in more LSG patients (37.5 vs. 0%, p = 0.04). The mean time between leak diagnosis and its resolution was 57.8 and 44.2 days, for LSG and LRYGB patients, respectively.
Conclusion
The diagnosis of leak tends to be earlier in LRYGB patients. Endoscopic therapies are more frequently required in the management of leaks following LSG, while in those following LRYGB, drainage alone leads to resolution of leak in the majority of cases.
