Risk factors of pancreatic leakage after pancreaticoduodenectomy

AIM: To analyze the risk factors for pancreatic leakage after pancreaticoduodenectomy (PD) and to evaluate whether duct-to-mucosa pancreaticojejunostomy could reduce the risk of pancreatic leakage. METHODS: Sixty-two patients who underwent PD at our hospital between January 2000 and November 2003 were reviewed retrospectively. The primary diseases of the patients included pancreas cancer, ampullary cancer, bile duct cancer, islet cell cancer, duodenal cancer, chronic pancreatitis, pancreatic cystadenoma, and gastric cancer. Standard PD was performed for 25 cases, PD with extended lymphadenectomy for 27 cases, pylorus-preserving PD for 10 cases. A duct-to-mucosa pancreaticojejunostomy was performed for patients with a hard pancreas and a dilated pancreatic duct, and a traditional end-to-end invagination pancreaticojejunostomy for patients with a soft pancreas and a non-dilated duct. Patients were divided into two groups according to the incidence of postoperative pancreaticojejunal anastomotic leakage: 10 cases with leakage and 52 cases without leakage. Seven preoperative and six intraoperative risk factors with the potential to affect the incidence of pancreatic leakage were analyzed with SPSS10.0 software. Logistic regression was then used to determine the effect of multiple factors on pancreatic leakage. RESULTS: Of the 62 patients, 10 (16.13%) were identified as having pancreatic leakage after operation. Other major postoperative complications included delayed gastric emptying (eight patients), abdominal bleeding (four patients), abdominal abscess (three patients) and wound infection (two patients). The overall surgical morbidity was 43.5% (27/62). The hospital mortality in this series was 4.84% (3/62), and the mortality associated with pancreatic fistula was 10% (1/10). Sixteen cases underwent duct-to-mucosa pancreaticojejunostomy and 1 case (1/16, 6.25%) developed postoperative pancreatic leakage, 46 cases underwent invagination pancreaticojejunostomy and 9 cases (9/46, 19.6%) developed postoperative pancreatic leakage. General risk factors including patient age, gender, history of jaundice, preoperative nutrition, pathological diagnosis and the length of postoperative stay were similar in the two groups. There was no statistical difference in the incidence of pancreatic leakage between the patients who received the prophylactic use of octreotide after surgery and the patients who did not undergo somatostatin therapy. Moreover, multivariate logistic regression analysis showed that none of the above factors seemed to be associated with pancreatic fistula. Two intraoperative risk factors, pancreatic duct size and texture of the remnant pancreas, were found to be significantly associated with pancreatic leakage. The incidence of pancreatic leakage was 4.88% in patients with a pancreatic duct size greater than or equal to 3 mm and was 38.1% in those with ducts smaller than 3 mm (P = 0.002). The pancreatic leakage rate was 2.94% in patients with a hard pancreas and was 32.1% in those with a soft pancreas (P = 0.004). Operative time, blood loss and type of resection were similar in the two patient groups. The incidence of pancreatic leakage was 6.25% (1/16) in patients with duct-to-mucosa anastomosis, and was 19.6% (9/46) in those with traditional invagination anastomosis. Although the difference of pancreatic leakage between the two groups was obvious, no statistical significance was found. This may be due to the small number of patients with duct-to-mucosa anastomosis. By further analyzing with multivariate logistic regression, both pancreatic duct size and texture of the remnant pancreas were demonstrated to be independent risk factors (P = 0.007 and 0.017, OR = 11.87 and 15.45). Although anastomotic technique was not a significant factor, pancreatic leakage rate was much less in cases that underwent duct-to-mucosa pancreaticojejunostomy. CONCLUSION: Pancreatic duct size and texture of the remnant pancreas are risk factors influencing pancreatic leakage after PD. Duct-to-mucosa pancreaticojejunostomy, as a safe and useful anastomotic technique, can reduce pancreatic leakage rate after PD.

猪作为胰胆管造影操作模型的实验研究

内镜下逆行性胰胆管造影（endoscopic retrograde cholangiopancreotography．ERCP）是在十二指肠镜直视下经十二指肠乳头注入造影剂作X线胰胆管造影检查，是胰腺、胆道等疾病的重要诊治手段之一。通过ERCP．可以进行乳头括约肌切开术、胆胰管取石、支架植入和狭窄扩张。此项微创技术需要经验丰富的内镜医师操作，初学者操作有一定风险.     

胆汁反流、胃酸和幽门螺杆菌感染共同作用对胃黏膜损伤程度和分布的影响

背景:胆汁反流、胃酸和幽门螺杆菌（H.pylori）感染均是胃黏膜损伤的独立致病因素。然而,它们共同存在时有无协同致病作用尚不清楚。目的:探讨胆汁反流、胃酸和H.pylori感染共同作用对胃黏膜损伤程度和分布的影响。方法:37例胃镜检查疑有十二指肠胃反流者均经24h胃内胆汁监测证实,同时行胃内PH监测。胃体和胃窦黏膜有或无活动性炎症、萎缩、肠化和不典型增生分别记2分或1分。分别以胃体和胃窦黏膜的各项病理学改变为应变量,以胃内胆红素吸收值>0.14的时间百分比、pH<4的时间百分比和H.pylori感染状态指标为自变量进行多变量逐步Logistic回归分析。结果:37例患者胃内胆红素吸收值>0.14的时间百分比为34.49％±22.69％,pH<4的时问百分比为78.68％土 9.91％,H.pylori阳性率为29.73％。胆汁反流出现在以胃体和胃窦黏膜肠化以及胃体黏膜活动性炎症为应变量的Logistic回归模型中,H.pylori出现在以胃体黏膜活动性炎症为应变量的回归模型中。结论:胆汁反流是胃黏膜肠化的危险因素;胃内有胆汁反流存在时,H.pylori感染是导致胃体新膜炎症的重要病因。
