The hazards of sleeve gastric surgery include, postoperative anastomotic fistula, gastroesophageal reflux, postoperative vomiting, and weight loss failure.
1. Postoperative anastomotic fistula, about 2-4% of patients will develop gastric fistula after sleeve gastrectomy, poor healing ability, reflux increases the resistance to emptying, leading to fistula, distal mechanical or functional obstruction is also a common cause of persistent fistula.
2. Gastroesophageal reflux, a variety of causes can lead to gastroesophageal reflux after laparoscopic sleeve gastrectomy, including decreased cardia pressure, structural and functional disruption, decreased gastric compliance, increased intragastric pressure, slow gastric emptying, advanced gastric dilatation and esophageal hiatal hernia.
3. Postoperative vomiting, nausea and vomiting are common and severe within 24 hours after laparoscopic sleeve gastrectomy, and most of them are reduced or disappeared after 24 hours.
4. Failure of weight loss, some patients rebound to a certain extent 2 years after surgery, so it is important to provide nutritional and dietary guidance to weight loss patients after surgery, and urge patients to implement diet and exercise programs to maintain the effect of weight loss, which can effectively prevent the occurrence of regaining weight.
If the above situation occurs, it is recommended that patients seek medical treatment as soon as possible.
