Abstract
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is shown to have durable and sustained weight reduction outcomes and improvement in comorbid conditions in patients with severe clinical obesity. Discussions regarding "proper" staple height for various gastric locations continue. We propose a standard approach of consistent use of single staple load height and bioabsorbable staple line reinforcement during the LSG to reduce variability. METHODS: A retrospective chart review of 2556 consecutive cases of adult patients who underwent LSG evaluated perioperative complications, postoperative leaks or bleeding, and average weight and body mass index (BMI) change and excess weight loss (EWL) at 6, 12, and 24 months. The same green staple load (2.0 mm) and staple line reinforcement were used in all cases for all staple firings, regardless of patient size or gastric location. RESULTS: Patients were a mean age of 42 years, 87.3% were female, and the mean preoperative weight was 134.2 kg and BMI was 48.2 kg/m2. No staple line leak was detected. Three bleeding events occurred but did not require readmission or rehospitalization. Mean EWL and BMI, respectively, were 49.0% and 35.5 kg/m2 at 6 months, 69.8% and 29.6 kg/m2 at 12 months, and 70.0% and 29.5 kg/m2 at 24 months. CONCLUSION: In this case series of 2556 consecutive LSG performed by a single surgeon, clinically meaningful EWL and decreased BMI were achieved. Streamlining the LSG procedure by utilizing the same staple height and a bioabsorbable staple line reinforcement proved safe with minimal complications.
