Objective To investigate the risk factors and preventions of functional delayed gastric emptying (FDGE) after pylorus-preserving pancreatoduodenectomy (PPPD). Methods The clinical data of 41 patients after undergoing PPPD between 2003 and 2009 in this hospital were analyzed retrospectively.Results In all 41 cases, postoperative complications developed in 13 patients (31.7%), in which 7 patients developed FDGE (17.1%). The complications excluding FDGE (P=0.010) and diabetes (P=0.024) had remarkable relations with the FDGE in the univariate analysis; Compared with the non-FDGE patients, the albumin was declined obviously (P=0.020) while the serum direct bilirubin increased significantly (P=0.036) in the FDGE patients, while the development of FDGE had relation only with the albumin (P=0.039) and the complication of diabete (P=0.047) by the binary logistic regression analysis. Conclusion In the patients undergoing PPPD, preoperative control of the blood glucose, preoperative correction of hypoproteinemia and hyperbilirubinemia, and centralizing PPPD in high-volume have possibly positive significance for the prevention of FDGE.
ObjectiveTo compare the effectiveness of antecolic duodenojejunostomy (ADJ) and retrocolic duodenojejunostomy (RDJ) after pylorus-preserving pancreaticoduodenectomy (PPPD). MethodsRandomized controlled trials (RCTs) of ADJ versus RDJ after PPPD were searched in Cochrane Library, PubMed database, Embase database, Web of Science, Chinese biomedicine database, CNKI database, VIP database, and Wanfang database from inception to April 2014, as well as Google. After quality assessment of RCTs according to the Cochrane Handbook for Systematic Reviews of Interventions Version, Meta analysis was performed by RevMan 5.1 software. ResultsFour RCTs of 462 patients in total were included in this Meta-analysis. The results of Meta-analysis showed that, there were no significant differences in the operation time (MD=14.02, 95% CI:-41.42-69.46, P=0.62), incidence of postoperative complications (RR=1.09, 95% CI:0.81-1.48, P=0.56), incidence of delayed gastric emptying (RR=0.63, 95% CI:0.31-1.28, P=0.20), incidence of pancreatic fistula (RR=1.13, 95% CI:0.72-1.75, P=0.60), incidence of abdominal abscess (RR=0.92, 95% CI:0.54-1.58, P=0.77), and mortality (RR=0.61, 95% CI:0.24-1.60, P=0.32) between ADJ group and RDJ group. ConclusionsThe effectiveness of ADJ is similar with RDJ after PPPD, so the reconstruction way after PPPD can be routed according to the surgeon's preference.
ObjectiveTo investigate the feasibility and security of laparoscopic Whipple pancreaticoduodenectomy(LPD)or laparoscopic pylorus preserving pancreaticoduodenectomy(LPPPD)for the patients with periampullary diseases, estimate the ratio of postoperative complications between LPD and LPPPD. MethodsFourty-five patients who underwent the LPD or LPPPD from January 2010 to March 2014 were reviewed retrospectively. These patients were divided into LPD group and LPPPD group basing on the Whipple or polyrus preservation. ResultsAmong these 45 patients, 25 patients were performed the LPD, the other 20 patients were performed the LPPPD. There were 25(55.56%)complications after operation, including 10 cases of pancreatic fistula, 1 case of bile leakage, 6 cases of delayed gastric emptying, 3 cases of infection, 2 cases of stomach intestine stomatorrhagia, 1 case of mesenteric venous thrombosis, 1 case of ascites, 1 case of chylous fistula. The complication rate had no significant difference between two groups. One patient died after operation in the LPPPD group. ConclusionLaparoscopic pancreaticoduodenectomy is safe and feasible in the treatment of periampullary diseases, the LPPPD could partly prevent the occurrence of reflux of the digestive juice following the resection of pylorus and improve the quality of life.
Objective This study was conducted to evaluate and analyze the clinical effect between subtotal stomach-preserving pancreaticoduodenectomy (SSPPD) and pylorus-preserving pancreaticoduodenectomy (PPPD), especially compare the incidences of delayed gastric emptying (DGE) between them. Methods The documents about SSPPD and PPPD were searched in Cochrane Library, PubMed database, Embase database, Web of Science, Chinese biomedicine database, CNKI database, VIP database, and WanFang database. The quality of included studies was assessed according to the Cochrane systematic review methods, and statistical analysis of data was performed by using RevMan 5.3 software. Firstly, comparison of incidence of DGE and other effective indexes between SSPPD group and PPPD group was performed by enrolling all included studies, whether met the DGE standards of International Study Group of Pancreatic Surgery (ISGPS) or not, and then comparison of incidence of DGE and clinical DGE was performed by enrolling included studies that met the DGE standards of ISGPS. Results Ten studies were included, with a total of 804 patients, in which, 433 cases underwent SSPPD and 371 cases underwent PPPD. The results of meta-analysis indicated that, in all the included studies, the total incidence of DGE〔OR = 0.33, 95%CI is (0.17, 0.63),P = 0.000 9〕, and the time of nasogastric tube〔MD = –2.65，95%CI is (–4.49, –0.80),P = 0.005〕, and time of stared liquid diet〔MD = –4.13, 95%CI is (–7.35, –0.91),P = 0.01〕 showed significant differences. The total incidence of DGE, the time of nasogastric tube, and time of stared liquid diet were less in SSPPD group. But there was no significant difference between the SSPPD group and PPPD group in operating time, intraoperative blood loss, time of started solid diet, hospital stay, and incidences of reinsertion of nasogastric tube, pancreatic fistula, intra-abdominal abscess, reoperation, wound infection, postoperative hemorrhage, and mortality (P>0.05). In the 8 studies adopted DGE standard of ISGPS, the total incidence of DGE〔OR = 0.31, 95%CI is (0.15, 0.65)，P = 0.002〕 and incidence of clinical DGE 〔OR = 0.13，95%CI is (0.05, 0.40),P = 0.000 3〕showed significant differences. The total incidence of DGE and incidence of clinical DGE were both lower in SSPPD group. Conclusions Compared with PPPD group, SSPPD group was associated with significantly less incidence of DGE. Meanwhile, the time of the nasogastric tube and started liquid diet are shorter than those of SSPPD. And there is no significant difference in the other aspects.
