Stool stomach pain after pancreatic surgery may be caused by wound irritation, postoperative infection, poor diet and so on. 1. Wound stimulation: when the patient has just finished pancreatic surgery, the wound is not fully recovered, and the increased intra-abdominal pressure during bowel movement may easily lead to increased wound tension, which may cause the patient’s stomach pain. 2. Post-operative infection: after surgery, the wound will be created in the organ tissues, if the post-operative care is not good, it is easy to lead to wound infection, and then redness, swelling, heat and pain and other inflammatory manifestations, which can lead to obvious abdominal pain during bowel movement. 3. Poor diet: after pancreatic surgery, if patients do not pay attention to diet, it is easy to lead to abnormal gastrointestinal digestive function, resulting in gastrointestinal peristaltic disorder, so that the patient has symptoms such as abdominal pain in stool. After pancreatic surgery, patients should actively go to the hospital for examination, so as not to delay the diagnosis and treatment.
