With unresectable lesions, long-term survival is extremely rare, and surgery remains the only curative option for pancreatic cancer. An aggressive approach by applying extended distal pancreatectomy with the resection of the celiac axis may increase the resectability and analgesic effect but great care must be taken with the arterial blood supply to the liver and stomach. Sometimes, accidental injury to the pancreatoduodenal artery compromises collateral blood flow and leads to fatal complications. Therefore, knowledge of any alternative restoration of the compromised collateral flow before surgery is essential. The present case report shows a patient with a pancreatic body cancer in whom the splenic, celiac, and common hepatic arteries were involved with the tumor, which extended almost to the root of the gastroduodenal artery. We modified the procedure by reanastomosis between the proper hepatic artery and middle colic artery without vascular graft. The postoperative course was uneventful, and the patient was discharged on post-operative day 19. The patient was immediately free of epigastric and back pain.展开更多

We dividedthese patients into two groups: 131 patients with a stent inserted into the pancreatic head(head group) and 16 patients with a stent inserted up to the pancreatic body or tail(body/tail group). Patient characteristics and ERCP factors were compared between the groups.RESULTS Pancreatic amylase isoenzyme(p-AMY) levels in the head group were significantly higher than those in the body/tail group [138.5(7.0-2086) vs 78.5(5.0-1266.5), P = 0.03] [median(range)]. No cases of PEP were detected in the body/tail group [head group, 12(9.2%)]. Of the risk factors for post-ERCP hyperamylasemia(≥ p-AMY median, 131 IU/L), procedure time ≥ 60 min [odds ratio(OR) 2.65, 95%CI: 1.17-6.02, P = 0.02) and stent insertion into the pancreatic head(OR 3.80, 95%CI: 1.12-12.9, P = 0.03) were identified as independent risk factors by multivariate analysis.CONCLUSION Stent insertion up to the pancreatic body or tail reduces the risk of post-ERCP hyperamylasemia and may reduce the risk of PEP.展开更多
