Complications after laparoscopic sleeve gastrectomy: can we approach a 0% rate using the largest staple height with reinforcement all along the staple line? Short-term results and technical considerations

Background: Laparoscopic sleeve gastrectomy (SG) is gaining acceptance among bariatric surgeons as a viable option for treating morbidly obese patients. We describe the results of a single center's experience with SG, revealing a low complication rate. Objectives: The aim of the study was to analyze the short-term results of laparoscopic SG using exclusively black staples with staple-line reinforcement. Settings: University hospital, tertiary referral center for bariatric surgery. Methods: SG was performed in 434 consecutive patients from December 2014 to March 2017. A technique is described where all operations were performed with attention to avoiding strictures at the incisura angularis and not stapling near the esophagus at the angle of His. All the interventions were performed using black cartridges and staple-line reinforcement using bioabsorbable Seamguard. A prospective chart review was conducted to determine the occurrence of early complications. Results: Follow-up data were collected for all patients at 90 days postoperatively. A total complication rate of 4.4% was observed. No leaks occurred in any of the patients. One case of bleeding occurred that necessitated a surgical exploration, which found the origin of the bleeding to be a diaphragmatic vessel. The 90-day mortality rate was 0%. Conclusion: SG can be performed with a low complication rate. Selection of the appropriate staple height and reinforcement of the staple line could play a major role in optimizing the results of SG.
