Complications of gastric sleeve resection mainly include bleeding, anastomotic fistula, gastroesophageal reflux, and nutritional complications. 1. Bleeding: Postoperative bleeding mainly includes intragastrointestinal bleeding or intraperitoneal bleeding, which is mainly caused with inaccurate hemostasis or loosening of vascular ligature. It can be treated conservatively by endoscopic hemostatic clip, spraying hemostatic powder, etc. Those who have no relief may need another operation to stop bleeding. 2. Anastomotic fistula: anastomotic fistula may be caused by ischemic necrosis of the gastric wall due to insufficient blood supply, gastric fluid into the abdominal cavity may lead to peritonitis, which is more difficult to deal with and takes longer time. 3. Gastroesophageal reflux: Sleeve gastrectomy is to remove part of the stomach to make it narrowed to a tube stomach, gastric content volume is reduced, the pressure inside the stomach is easy to rise, gastric juice or gastric contents back into the esophagus can lead to gastroesophageal reflux disease, reflux esophagitis, the need for long-term treatment of omeprazole and other medications, which may affect the quality of life. 4. Nutritional complications: the reduced stomach capacity after sleeve gastrectomy affects digestion and absorption, and symptoms such as anemia, emaciation and epigastric fullness may occur. Dietary habits should be adjusted, such as smaller meals. Sleeve gastrectomy is mainly applicable to obesity and other metabolic diseases.
