Objective To summarize preliminary experience of laparoscopic pancreaticoduodenectomy for periampullary carcinoma. Method The clinical data of patients with periampullary carcinoma underwent laparoscopic pancreaticoduodenectomy from July 2016 to September 2016 in the Shengjing Hospital of China Medical University were analyzed retrospectively. Results Two patients underwent complete laparoscopic pancreaticoduodenectomy, 2 patients underwent laparoscopic resection and anastomosis assisted with small incision open. The R0 resection and duct to mucosa pancreaticojejunal anastomosis were performed in all the patients. The operative time was 510–600 min, intraoperative blood loss was 400–600 mL, postoperative hospitalization time was 15–21d, postoperative ambulation time was 6–7 d. Three cases of pancreatic fistula were grade A and all were cured by conservation. No postoperative bleeding, delayed gastric emptying, intra-abdominal infection, and bile leakage occurred. The postoperative pathological results showed that there was 1 case of pancreatic head ductal adenocarcinoma, 1 case of cyst adenocarcinoma of pancreas uncinate process, 1 case of papillary carcinoma of duodenum, and 1 case of terminal bile duct carcinoma. Conclusion The preliminary results of limited cases in this study show that laparoscopic pancreaticoduodenectomy has been proven to be a safe procedure, it could reduce perioperative cardiopulmonary complications, its exhaust time, feeding time, and postoperative ambulation time are shorter, but its operative complications could not be reduced.
ObjectiveTo compare surgical safety and postoperative efficacy of total mesopancreas excision (TMpE) with pancreaticoduodenectomy (PD) and standard PD (Whipple).MethodsA total of 123 patients underwent PD in the Affiliated Hospital of Southwest Medical University from August 2013 to December 2017 were included, including 47 patients with pancreatic head carcinoma and 76 patients with periampullary carcinoma, then were divided into a TMpE group and a Whipple group respectively. The operative time, intraoperative blood loss, postoperative hospitalization time, postoperative recovery time of gastrointestinal function, postoperative complications, and postoperative survival of patients with the same site between the Whipple group and the TMpE group were retrospectively compared.Results① There were no significant differences in the baseline data between the TMpE group and the Whipple group in the pancreatic head carcinoma and periampullary carcinoma (P>0.05). ② For the patients with pancreatic head carcinoma, there were no significant differences in the operative time, postoperative hospitalization time, and postoperative gastrointestinal function recovery time between the TMpE group and the Whipple group (P>0.05), but the intraoperative blood loss in the TMpE group was significantly higher than that in the Whipple group (P=0.038); For the patients with periampullary carcinoma, the above indexes had no significant differences between the TMpE group and the Whipple group (P>0.05). ③ The total incidence of complications in the TMpE group was significantly higher than that in the Whipple group for the patients with pancreatic head carcinoma (χ2=6.595, P=0.010), which had no significant difference between the TMpE group and the Whipple group for the patients with periampullary carcinoma (P>0.05). ④ The cumulative survival curve in the TMpE group was better than that in the Whipple group for the patients with pancreatic head carcinoma (χ2=9.597, P=0.002), which had no significant difference between the TMpE group and the Whipple group for the patients with periampullary carcinoma (χ2=0.844, P=0.358).ConclusionsFor patients with pancreatic head cancer, comparing with standard Whipple, although TMpE PD increases intraoperative blood loss and overall incidence of complications, it could significantly improve long-term survival and there are no significant differences in postoperative recovery time and operative safety between Whipple and TMpE; For patients with periampullary carcinoma, there are no significant differences in surgical safety, long-term survival rate, and survival time between TMpE and Whipple.
Objective To summarize the research status and progress of imaging diagnosis of periampullary carcinoma. Methods The literatures on imaging diagnosis of periampullary carcinoma were reviewed. Results At present, the commonly used imaging diagnosis methods for periampullary carcinoma mainly include ultrasound, CT, MRI, and endoscopic retrograde cholangiopancreatography. Some other new imaging techniques had also been applied in the diagnosis and evaluation of periampullary carcinoma. Conclusions Different imaging methods have their own advantages and disadvantages in the diagnosis of periampullary carcinoma. Therefore, the detection rate and diagnostic accuracy of periampullary carcinoma can be improved by rational selection of imaging techniques or combined application of multiple techniques.
