Intraoperative occurrence of intra-abdominal dry compression syndrome is very frightening and frightening. It is difficult to say exactly why intraoperative dry abdominal compression occurs. It is very frightening when it occurs. Especially in pancreatic head duodenectomy, the stomach has been cut off and the blood supply of the proximal stomach mainly comes from the left gastric artery and splenic artery. When there is abdominal dry compression, the blood flow of the left gastric artery and splenic artery is interrupted and the blood supply of the preserved proximal stomach will be impaired; likewise, the pancreas will be ischemic or even necrotic because of the impaired blood supply of the splenic artery; the pancreas is less tolerant to ischemia and is more likely to have pancreatic necrosis or anastomotic leak. In pancreatic head duodenectomy, the ischemia of the abdominal stem compression artery should be detected promptly. Because, in general, the operator does not expect such a situation to occur and there is no special manifestation of arterial ischemia, therefore, it is not easy to detect it in time. In the case of abdominal trunk ischemia, the pulsation of the abdominal trunk and its branch arteries disappears or is significantly weakened, and the tension is significantly reduced. Once the abdominal trunk is found to be suddenly interrupted, the left gastric artery and common hepatic artery should be immediately distracted to reveal the abdominal trunk, and the nerves and connective tissues surrounding the abdominal trunk should be severed by peeling along the abdominal trunk to its root. Immediately after the severance of this fasciculus, the pulsation of the arteries of the branches of the abdominal trunk was seen to recover and to get better. The consequences are unimaginable if this symptom is not recognized, if it is detected late, or if the condition is detected but not treated, or if it is not treated effectively.
