Abdominal distension in patients with intestinal obstruction after surgery is relatively common in clinical practice, most of which is caused by the temporary decline of gastrointestinal function caused by surgery. At this time, symptomatic treatment is enough, including external use of Kaisailu, internal use of paraffin oil, or treatment through enema, or abdominal puncture to aspirate gas when necessary. But for abdominal puncture of patients with abdominal distension, be careful to avoid puncturing the inflated intestines. If postoperative abdominal distension is caused by incomplete surgical treatment, there is a certain probability that secondary surgical treatment should be considered to alleviate the symptoms, but this situation is relatively rare. For intestinal obstruction, it is ineffective after conservative treatment, and surgery should be performed as soon as possible.
