Introduction: Laparoscopic Sleeve Gastrectomy (LSG) has become the most commonly performed bariatric procedure. LSG is known for its safety and effectiveness, shorter operative time, feasibility, and easiness of revision and conversion to a malabsorptive surgery. Surgeons are tailoring different techniques to avoid complications from arising. Twisting of the sleeved gastric tube is one of the causes of sleeve obstruction and persistent nausea and vomiting. This study aims to compare between the postoperative complications in sleeve gastrectomy with and without posterior fixation.
Patients and methods: In this prospective comparative cohort study 643 patients were included; divided into
two groups according to the surgical technique. Group 1 included 364 LSG operations without fixation and Group 2
included 279 LSG with sleeve fixation. The operations were performed at Ain Shams University Hospitals between
June 2017 and June 2021. Fixation of the sleeve was performed by two or three absorbable stitches to the prepancreatic fascia and root of the mesocolon. Incidence of postoperative complications were compared in each group.
Results: There were no statistically significant differences in baseline characteristics between the two groups
included in the study. Group 2 showed highly significant increase in operative time (p<0.001) the overall incidence
of complications was significantly less in the fixation group (p <0.0001). Incidence of vomiting, bleeding, GERD and
re-operation was significantly lower in group 2 (p<0.05).Seven patients from group 1 were diagnosed with gastric
twist as post operative complication with one patient suffering from leakage compared to three patients in group
2. There were no mortalities in both groups.
Conclusion: Adding posterior fixation to LSG ensures decreases incidence of complications. Many randomized
controlled trials are needed to draw a solid outcome.
