Objective To investigate the new method of pancreaticoenterostomy and decrease the probability of complications like pancreatic fistula etc. Methods By using the absorbable bandage and ear-brain glue, modified sutureless pancreaticoenteromy was made in 10 swines. Experimental data includes： routine analysis of blood, levels of amylase in blood and abdominal drainage and lipase in blood and abdominal drainage. The tissues in anastomosis were taken for pathology examination in 1 month after operation. Results The average operative time was （35±10） min.Nine of ten animals had no pancreatic fistula and survived. The levels of amylase and lipase in abdominal drainage were both normal. One swine had a evident abdominal distensile on 2 days after operation, the level of amylase was 10 000u/L,then died on 10 days after operation. Pancreatic fistula and infection were found because of the loss of stent in pancreatic duct. Conclusions Comparison with traditional operation, the modified sutureless pancreaticoenteromy can also control the probability of pancreatic fistula. And this method can be hoped to be one of the routine operations of pancreaticoenterostomy because of its simplicity and practicality.
目的探讨如何降低胰十二指肠切除术后胰空肠吻合口漏的发生。方法采用胰管空肠吻合胰腺残端套入法行胰肠吻合，按胰、胆、胃顺序与空肠重建消化道。结果27例胰十二指肠切除术中，手术并发症7例（25.93%），其中应激性溃疡出血3例，胃排空延迟2例，腹腔及腹壁创口感染各1例，均经非手术治愈。全组无围手术期死亡，亦无一例发生胰瘘。结论胰瘘的发生同术式和操作技术密切相关，亦与吻合口部位血供和张力以及吻合口远端通畅与否有关。本术式增加了胰空肠吻合的严密性，对预防胰瘘的发生起到了积极的效果，且操作简便，易于掌握，效果可靠。
ObjectiveTo investigate the application of imbedding pancreaticojejunostomy in pure laparoscopic pancreaticoduodenectomy. MethodsEighty-five cases of laparoscopic pancreaticoduodenectomy in our hospital from May 2014 to December 2015 were analyzed retrospectively. According with inclusion criteria and exclusion criteria, 78 cases were investigated. They were divided into pancreatic duct-to-jejunum mucosa pancreaticojejunostomy group as controlled group (n=42) and imbedding pancreaticojejunostomy (technique of duct-to-mucosa PJ with transpancreatic interlocking mattress sutures) group as modified group (n=36). The rates of pancreatic fistula, abdominal infection/abscess, bile leakage, delayed gastric emptying, gastrointestinal/intraabdominal hemorrhage, pulmonary infection, and incision infection were investigated as well as hospital stays and pancreaticojejunostomy time in two groups were compared. ResultsThe rate of pancreatic fistula especially B to C grade pancreatic fistula in the modified group was obviously lower compared with which in the controlled group (8.3% vs. 31.0%, P < 0.05), pancreaticojejunostomy time ofmodified group was significantly shortened [(35.6±12.4) min vs. (52.8±24.6) min, P < 0.05] and total operative time also shortened [(322.4±23.6) min vs. (384.2±30.2) min, P < 0.05). There were no significant difference of the rates of abdominal infection/abscess, bile leakage, delayed gastric emptying, gastrointestinal/intraabdominal hemorrhage, pulmonary infection, ?incision infection, and hospital stays (P > 0.05)]. Conciusions The type of pancreaticojejunostomy has a significant impact on the rate of pancreatic fistula after laparoscopic pancreaticoduodenectomy. Imbedding pancreaticojejunostomy can decrease the rate of pancreatic fistula after operation, and shorten the pancreaticojejunostomy time and total operative time.
ObjectiveTo investigate the clinical effect of “Double R” pancreatojejunostomy in laparoscopic pancreaticoduodenectomy (LPD).MethodsThe clinical data of 20 patients underwent “Double R” pancreaticojejunostomy in the LPD from November 2018 to December 2019 in this hospital were collected retrospectively. The duration of pancreaticojejunostomy, incidence of postoperative pancreatic fistula, incidence of other complications, mortality, length of stay, and other clinical outcomes were analyzed.ResultsThere were 5 males and 6 females. The age was (56±10) years old. The body mass index was (22.6±4.4) kg/m2. The LPDs were successfully performed in all 20 patients, no patient transferred to the laparotomy, and no patient died within 30 d. There were 6 patients with papillary adenocarcinoma of the duodenum, 5 patients with adenocarcinoma of the lower part of the common bile duct, 2 patients with adenocarcinoma of the pancreatic duct, 3 patients with serous cystadenoma of the pancreatic head, 2 patients with intraductal papillary myxoma of the main pancreatic duct of the pancreatic head, 1 patient with duodenal adenoma with high grade intraepithelial neoplasia, 1 patient with metastatic renal clear cell carcinoma of the pancreatic head, 5 patients with soft pancreas, 12 patients with medium texture, 3 patients with hard texture. The diameter of distal pancreatic duct was (2.1±1.7) mm. The operative time was (380±69) min, the duration of pancreaticojejunostomy was (29±15) min, the intraoperative blood loss was (180±150) mL, the postoperative time of anal exhaust (2.2±0.8) d, postoperative time of fluid intake (3.5±1.1) d, postoperative time of half fluid intake (5.5±0.7) d, postoperative time of hospitalization (14±10) d. There were 3 complications in 2 patients, one of which suffered the pulmonary infection, the other suffered the delayed gastric emptying and gastrointestinal anastomosis bleeding, no bile leakage and abdominal hemorrhage happened. There were 2 cases of pancreatic fistula after the operation, all of them were biochemical pancreatic fistula.Conclusions“Double R” pancreaticojejunostomy method has some advantages of convenient operation, short operation time, and low incidence of pancreatic fistula. However, due to the limited sample size, its safety and feasibility still need to be verified by larger samples and more institutions.
