What is Sleeve Gastrectomy Complications?

Both early and late complications can develop after sleeve gastrectomy (gastric sleeve) surgery. The most serious complication is staple line leak, which usually occurs at the proximal staple line near the gastroesophageal junction. The incidence is approximately 1-3%.

Other complications include staple line bleeding (1-6%), stenosis/stricture (0.1-3.9%), gastroesophageal reflux, sleeve dilation, nutritional deficiencies (B12, iron, folate), and postoperative nausea-vomiting. Stenoses are most often seen at the incisura angularis.

Complication management requires a multidisciplinary approach. Endoscopic stent, fibrin glue, clipping, or surgical revision for leak; endoscopic dilation or seromyotomy for stenosis; Roux-en-Y gastric bypass revision for refractory reflux may be needed. Early diagnosis and treatment improve outcomes.

Symptoms

Postoperative early tachycardia, fever, abdominal pain (leak)
Postprandial vomiting, food impaction sensation (stenosis)
Heartburn, regurgitation (reflux)
Melena, hematemesis, or hemoglobin drop (bleeding)
Loss of appetite, food intolerance
Cessation or regain of weight loss
Anemia, fatigue (micronutrient deficiencies)

Risk Factors

Pre-existing GERD
Diabetes mellitus and impaired wound healing
Advanced age and malnutrition
