Objective@#To evaluate the safety and feasibility of laparoscopic radical antegrade modular pancreatosplenectomy(Lap-RAMPS) for left-sided pancreatic adenocarcinoma.@*Methods@#Clinical data of total 12 patients underwent Lap-RAMPS for left-sided pancreatic adenocarcinoma at Department of Gastrointestinal and Pancreatic Surgery, Zhejiang Provincial People′s Hospital from March 2016 to August 2017 were reviewed retrospectively.There were 7 male patients and 5 female patients, with median age of 60.5 years old(47-68 years old). Abdominal enhanced CT, pancreatic MRI, PET-CT were performed on all patients to evaluate the lesion and exclude metastasis.Follow-up were done with out-patient clinic or telephone consultancy until October 2017.@*Results@#All patients underwent pure Lap-RAMPS.The medium operative time was 250 minutes(180-445 minutes), and the blood loss was 150 ml(50-500 ml). The medium first flatus time and diet resumption time were 3.0 days(1-5 days) and 3.5 days(1-7 days) respectively.The medium postoperative hospital stay was 9 days(4-18 days). Morbidity occurred in 8 patients with gastric empty delay(n=1), bleeding(n=1), fluid collection(n=3). There was no mortality.The medium overall number of retrived lymph nodes was 15.6 and the positive rate was 41.7%. The R0 rate was 100%.The medium follow-up was 10 months.One patient was diagnosed as liver metastasis after 8 months and accepted chemotherapy.One patient died after 14 months for tumor recurrence and metastasis.Others survived without tumor recurrence or metasitasis.@*Conclusion@#Lap-RAMPS is safe and feasible with accepted oncological outcomes for selected left side pancreatic adenocarcinoma under skilled hands.

Objective@#To summary the experience of 233 cases of laparoscopic pancreaticoduodenectomy (LPD) performed by a single surgical team.@*Methods@#Data of patients undergoing LPD from September 2012 to October 2016 were reviewed. There were 145 males and 88 females with the mean age of(60.3±13.0)years old, ranging from 19 to 92 years old, and the mean body mass index of (22.8±3.5)kg/m2, ranging from 16.3 to 36.8 kg/m2. There were 195 patients with clinical manifestation and 54 patients who had the history of abdominal surgery.@*Results@#LPD were performed on 233 patients by same surgical team consecutively. The mean operative time was(368.0±57.4)minutes. Mean blood loss was(203.8±138.6)ml. The postoperative morbidity rate was 33.5%, with 6.9% of grade B or C pancreatic fistula and 9.9% of bleeding. The reoperation rate was 5.6%. The mortality during 30 days after operation was 0.9%. Mean postoperative hospital stay was (18.1±11.2)days. Mean tumor size was (3.9±2.4)cm, and the mean number of lymph nodes harvested was 21.3±11.9.One hundred and sixty-three patients were diagnosed as malignant tumor, including pancreatic adenocarcinoma(n=84), cholangiocarcinoma(n=17), ampullary adenocarcinoma(n=55), duodenal adenocarcinoma(n=5), gastric cancer(n=1)and duel cancer (n=1) located in distal stomach and duodenum.@*Conclusion@#The key point to make laparoscopic pancreaticduodenectomy a routine safe procedure is to operate the procedure under skilled hands in selected patients via suitable surgical approaches.

<p><b>OBJECTIVE</b>To evaluate the safety and feasibility of laparoscopic gastrectomy for gastric stump cancer.</p><p><b>METHODS</b>Clinical and follow-up data of 7 patients who underwent laparoscopic gastrectomy for gastric stump cancer in our department from January 2008 to July 2015 were analyzed retrospectively.</p><p><b>RESULTS</b>There were 5 male and 2 female patients, with a mean age of (62.1±10.7) years. Initial gastrectomy was performed for gastric cancer in 3 patients and peptic ulceration in 4. The initial surgery was B-II( gastrojejunostomy in 6 patients and Roux-en-Y gastrojejunostomy in 1. Duration between primary gastrectomy and occurrence of gastric stump cancer was ranged from 6-30 years for peptic ulceration, and from 11-15 years for gastric cancer. During the operation, adhesiolysis and exploration to locate the tumor were performed. Following total remnant gastrectomy and lymphadenectomy, intracorporeal anastomosis was accomplished by Roux-en-Y reconstruction. The methods of intracorporeal esophagojejunostomy were end-to-side approach using a circular stapler in 1 patient, side-to-side approach using an endoscopic linear staple in 2 patients, and hand-sewn technique in 4 patients. The operation time was (247.1±17.5) minutes and the intraoperative blood loss was (100.0±30.8) ml without transfusion. The number of retrieved lymph node was 19.1±4.8. The first flatus time, diet resumption time, postoperative hospital stay were (3.3±1.5) days, (3.7±0.8) days, (9.4±2.6) days, respectively. One patient experienced gastrointestinal bleeding that was managed conservatively and ultimately cured. Seven patients were followed up till January 2016. After follow-up from 6 to 38 months, 1 patient died of peritoneal metastasis 17 months after surgery, and 1 patient died of Alzheimer's disease 19 months after surgery. The other 5 patients were still alive without metastasis or recurrence.</p><p><b>CONCLUSION</b>Laparoscopic gastrectomy for gastric stump cancer is feasible and safe.</p>
