Abstract

Background: Sleeve gastrectomy (SG) is the most common bariatric procedure performed worldwide. However, without a standardised surgical technique, heterogeneous outcomes and complications such as gastro-oesophageal reflux disease (GERD) have been reported. The aim of this study was to identify reproducible anatomical criteria for SG to obtain safe and effective results.

Methods: A prospective photographic study that captured every phase of each procedure was completed. The photographic documentation was carefully examined in order to identify anatomical criteria that would help make our technique reproducible. Postsurgical results were reported in terms of complications and mortality, while functional and morphological results were evaluated using 3-month upper gastrointestinal (UGI) series and 12-month computed tomography (CT) scan, respectively. BMI, percentage excess weight loss (%EWL), comorbidities, and GERD symptoms at 12 months were analysed.

Results: One hundred thirty-four consecutive laparoscopic SG were photographed, and four reproducible anatomical criteria were identified: (1) to preserve the gastric antral posterior ligament (GAPL); (2) to dissect the gastro-pancreatic ligament (GPL); (3) to expose the right edge of the left diaphragmatic crus; and (4) to ensure staple-line linearity. No leaks occurred, and only one patient needed relaparoscopy for staple-line hematoma. Mortality and 30-day readmission rates were null. Gastric tube morphologies on the 12-month CT scans were homogeneous. At 12 months, median BMI was 30.8 kg/m2 [IQR 20-47.2] and mean %EWL was 69.0 ± 24.5%; comorbidities resolved in 65.8-88.1% of patients, and GERD symptoms resolved in 44.4%.

Conclusion: The four anatomical criteria for SG that we propose are safe, effective, and reproducible and have acceptable postsurgical outcomes.
