Disadvantages of sleeve gastric surgery include immediate postoperative complications such as bleeding and anastomotic fistula, long-term complications such as malnutrition and reflux, as well as poor long-term results.
1. Immediate complications: intraoperative bleeding may occur due to inaccurate hemostasis, loose ligature, etc.; gastric incision fistula occurs at the bottom of the stomach; postoperative intestinal adhesions lead to intestinal obstruction and damage to the surrounding organs.
2. Long-term complications: Sleeve stomach surgery changes the shape of the stomach into a tube, the pressure inside the stomach rises and other factors lead to gastroesophageal reflux, acid reflux, belching (hiccups) and other symptoms; postoperative shrinkage of the stomach, digestive and absorption functions are affected, which can lead to malnutrition, epigastric fullness, anemia and other symptoms.
3. Poor long-term results: Sleeve gastric surgery is slightly less effective for long-term weight loss, treatment of diabetes, high blood cholesterol, etc. It is not as effective as gastric bypass and other weight-loss surgeries, and the rate of patients regaining weight is slightly higher.
It is recommended that patients should consult the doctor in time and choose the appropriate type of weight loss surgery according to their own situation.
