After appendicitis surgery, intestinal obstruction will lead to symptoms such as gas and defecation cessation as well as abdominal distension and vomiting, etc. The reasons for the corresponding conditions mainly include surgical stimulation, vascular injury and local adhesion.
1. Surgical stimulation: stimulation of intestinal tract during surgery may cause abnormal peristalsis, resulting in paralytic intestinal obstruction and corresponding symptoms.
2. Vascular injury: the mesenteric blood vessels are damaged during surgery, which affects the blood supply to the intestinal tract and causes a decrease in peristalsis, resulting in ischemic intestinal obstruction.
3. Local adhesion: exudation and infection of the surrounding tissues during surgery can cause intestinal adhesion, affecting intestinal peristalsis and food evacuation, resulting in adhesive intestinal obstruction.
When obvious intestinal obstruction accompanied by nausea and vomiting occurs after the surgery, it is necessary to consult a doctor in time and standardize the treatment under the guidance of the clinician to avoid delaying the condition.
