This survey is intended to investigate the current status of digestive tract reconstruction after PD in university hospitals in China. Method: A cross-sectional survey was conducted among the members of the Young Elite Pancreatic Surgery Club of China by using the Questionnaire for Digestive Tract Reconstruction after Pancreaticoduodenectomy. The questionnaire was disseminated and collected by point-to-point communication via WeChat public platforms. Results: A total of 73 valid questionnaires were returned from 65 university hospitals in 28 provincial divisions of mainland China. The respondents who performed PD surgery with an annual volume of over 100 cases accounted for 63%. Generally, laparoscopic PD was performed less often than open PD. Child and Whipple reconstructions accounted for 70% and 26%, respectively. The sequence of pancreatoenteric, biliary-enteric, and gastrointestinal reconstruction accounted for 84% of cases. In pancreatoenteric anastomosis, double-layer anastomosis is the most commonly employed type, accounting for approximately 67%, while single-layer anastomosis accounts for 30%. Of the double-layer anastomoses, duct-to-mucosa/dunking (94%/4%) pancreatojejunostomy was performed with duct-mucosa using the Blumgart method (39%) and Cattel-Warren (29%), with continuous/interrupted sutures in the inner layer (69%/31%) and continuous/interrupted sutures in the outer layer (53%/23%). In single-layer anastomosis, continuous/interrupted sutures accounted for 41%/45%. In hepatojejunostomy, single-layer/double-layer suture accounted for 79%/4%, and continuous/interrupted suture accounted for 75%/9%. Forty-six percent of the responding units had not applied double-layer biliary-intestinal anastomosis in the last 3 years, 75% of the responding surgeons chose the anastomosis method according to bile duct diameter, with absorbable/non-absorbable suture accounting for 86%/12%. PD/pylorus-preserving PD accounted for 79%/11% of gastrojejunostomy (GJ) cases, the distance between GJ and hepaticojejunostomy < 30, 30–50, and > 50 cm were 11%, 75%, and 14%, respectively. Antecolic/retrocolic GJ accounted for 71%/23% of cases. Twenty-two percent of GJ cases employed Braun anastomosis, while 55% and 19% of GJ cases used linear cutting staplers/tube-type staplers, respectively; 60%/14% were reinforced/not reinforced via manual suturing after stapler anastomosis. Manual anastomosis in GJ surgery employed absorbable/non-absorbable sutures (91%/9%). Significant differences in reconstruction techniques were detected between different volumes of PD procedures (<100/year and >100/year), regions with different economic development levels, and between north and south China.

The oncologic outcome in the early stage of pancreatic ductal adenocarcinomas (PDAC) operated by RPD has not been evaluated. Methods: Clinical data of pathology confirmed stage I PDAC from January 2015 to December 2020 in Ruijin hospital, Shanghai Jiao Tong University School of Medicine was collected and retrospectively analyzed. Patients were divided into the open pancreaticoduodenectomy (OPD) group and the RPD group. Clinicopathological data and prognosis data were compared and analyzed. Results: A total of 426 patients were enrolled in this study, including 342 patients in the OPD group and 84 patients in the RPD group. The baseline characteristics of both groups were equivalent. Incidence of R1 resection was significantly lower in RPD group (3 [3.6%] vs 40 [11.7%], P = .044).

R1 resection was associated with poor OS (HR: 1.483, 95% CI: 1.028–2.140, P = .035) while adjuvant therapy was associated with better OS (HR: 0.589, 95% CI: 0.452–0.766, P < .001).

Original articles, review articles, and meta-analyses relevant to the topic were selected. We found 2 to 4 cycles with FOLFIRINOX, gemcitabine plus nab-paclitaxel, gemcitabine plus S-1, or gemcitabine alone were the most acceptable treatments. Considering the risk of adverse events and cancer progression, NAT is considered safe and tolerable, with a comparable resection rate. Although NAT can result in moderate tumor responses and some extent of local control (improvement of complete resection rate and negative lymph node metastases), no obvious survival benefit is observed.

The purpose of this study was to evaluate the clinical efficacy and safety of RAIC. We searched literatures in databases such as PubMed, EMBASE, Cochrane Library, Web of Science, and CNKI. After screening, this meta-analysis finally included 9 randomized controlled trials (RCTs) with 444 patients (230 RAIC and 214 SIC). We used the Cochrane Risk of Bias 2.0 tool to assess risk of bias for included RCTs. Outcomes were overall survival (OS), overall response rate (ORR), adverse events rate (AER), and pain remission rate. Outcome indicators used relative risk (RR) and its 95% confidence interval (CI) as effect analysis statistics. The results showed that RAIC had some advantages over SIC in terms of ORR, OS, incidence of leukopenia, and pain remission. In conclusion, compared with SIC, RAIC has better clinical efficacy and lower toxicity in the treatment of advanced pancreatic cancer.","PeriodicalId":92925,"journal":{"name":"Journal of pancreatology","volume":"5 1","pages":"49 - 57"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42014405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
