ABSTRACT
Objective:To analyze the risk factors of clinically-relevant postoperative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy (PD) and penetrating pancreaticojejunostomy (PPJ).Methods:The clinical data of 108 patients who underwent PD and PPJ in the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Wannan Medical College from January 2017 to October 2022 were analyzed retrospectively, including 65 males and 43 females, aged 65.5 (54.2, 72.0) years. The incidences of POPF, biliary fistula, abdominal bleeding and other related complications were reviewed. The related factors of CR-POPF were analyzed by univariate analysis, and the statistically significant factors were included in multivariate logistic regression analysis.Results:A total of 108 patients were successfully treated with PD, including laparoscopic PD in 76 cases (70.4%) and open PD in 32 cases (29.6%). PPJ was performed in PD, including the continuous fashion in 39 cases (36.1%), intermittent fashion in 49 cases (45.4%) and modified continuous fashion in 20 cases (18.5%). The operation time was 390.0 (314.0, 480.0) min, the intraoperative blood loss was 200.0 (100.0, 384.0) ml, the postoperative hospital stay was 12.0 (10.0, 15.0) d, and the incidence of POPF (grade B + C) was 11.1% (12/108). Body mass index, pancreatic CT value and pancreatic duct size were the significant factors of CR-POPF (all P<0.05). Multivariate logistic regression analysis showed that age ( OR=0.895, 95% CI: 0.822-0.975), pancreatic CT value ( OR=0.812, 95% CI: 0.698-0.946) and pancreatic duct size ( OR=0.457, 95% CI: 0.220-0.952) were risk factors of CR-POPF after PPJ (all P<0.05). Conclusion:PPJ is a safe method of pancreaticoenterostomy, and CR-POPF may be related to younger patients, lower pancreatic CT value and the smaller pancreatic duct size.
ABSTRACT
Objective To study the reasons for conversion to laparotomy in laparoscopic pancreaticoduodenectomy (LPD).Methods Of the 74 patients who underwent LPD in Yi Jishan Hospital,Wan Nan Medical College from May 2012 to Dec 2016,7 patients were converted to laparotomy.The clinical and operative data of the 7 patients were reviewed.Results There were 6 males and 1 female.The age ranged was 51 to 66 years.The pathologies included tumor of pancreatic head in 5 patients,chronic inflammation of pancreas in 1 patient and duodenum papilla cancer in 1 patient.The reasons for conversion were:uncontrollable bleeding in 4 patients with superior mesenteric vein injury in 1 patient,portal vein injury in 1 patient and first jejunal vein injury in 2 patients,respectively.The bleeding was controlled successfully after laparotomy in all the 4 patients.The conversion in the remaining 3 patients were due to difficulty in the operative procedures which resulted from severe adhesions between the tumor and the major vessels.There were 2 patients who had invasion of the SMV by tumor.They underwent vascular resection after laparotomy.The remaining patient had chronic inflammation and the lesion was resected successfully after careful dissection.Of the 7 patients,1 patient developed pancreatic fistula,1 patient developed delayed gastric emptying and 1 patient developed both bile leakage and delayed gastric emptying.They were all treated conservatively.There was no peri-operative death in the study.Conclusion Uncontrollable bleeding and severe adhesions between the lesion and major vessels were the major reasons in LPD for conversion to laparotomy.
