[Preferably a gastric sleeve operation]. / Liever een 'gastric sleeve'-operatie.

One third of patients undergoing a gastric bypass operation will experience chronic abdominal symptoms. Diagnosis and treatment of this abdominal pain is a difficult task. The biggest problem is the ruling out of one of the possible causes of abdominal pain, such as internal herniation. Current diagnostic methods have generally not been successful in diagnosing internal herniation, and - more importantly - have not been able to rule out this diagnosis either. This leads to a high number of visits by these patients to the emergency department and outpatient clinic. Patients with pre-existing abdominal pain, or those who use analgesia preoperatively should preferably be treated by means of a gastric sleeve operation, instead of an operation involving anastomosis, such as a gastric bypass procedure.
