ABSTRACT
Objective To explore the clinical efficacies of laparoscopic distal pancreatectomy (LDP) with laparoscopic splenectomy (LS) for the treatment of malignant tumors in the body and tail of pancreas.Methods The clinical data of 37 patients with malignant tumors in the body and tail of pancreas who were admitted to the Third Affiliated Hospital of Guangzhou Medical University from June 2009 to December 2014 were retrospectively analyzed.LDP with LS was performed on all the patients under general anesthesia.The operation time,volume of intraoperative blood loss,postoperative complications,removal time of postoperative drainage tube,duration of hospital stay and results of pathological examinations were recorded.All the patients were followed up via outpatient examination and telephone interview up to May 2015.Results Thirty-seven patients received successful surgery without conversion to open surgery and perioperative death.Of 37 patients,19 received splenectomy due to splenic artery and vein surrounded by masses of pancreatic body and tail,splenic ischemia after clamping or amputating of splenic artery and vein;11 received splenectomy due to splenic hilum invasion,dense adhesions,unclear boundary and difficulty in preserving spleen;7 received splenectomy due to splenic cystic occupying lesion.The operation time,volume of intraoperative blood loss and removal time of drainage tube were (232 ± 42) minutes,(330 ± 160)mL and (5.0 ± 2.0)days,respectively.Four patients were complicated with pancreatic leakage without obvious discomfort and discharged from hospital with a placement of drainage tube,and then drainage tubes were removed after 2 weeks.The mean duration of postoperative hospital stay was 7.5 days (range,5.0-10.0 days).The results of pathological examination showed that resection margin was negative,moderate and low malignant intraductal papillary mucinous neoplasm (IPMN) was detected in 12 patients,mucinous cystic carcinoma in 9 patients,moderate and low malignant solid pesudopapillary neoplasm (SPN) in 7 patients,pancreatic ductal adenocarcinoma in 4 patients,pancreatic neuroendocrine cancer in 3 patients and acinic cell carcinoma in 2 patients.The number of detecting lymph node was (9 ± 3).All the patients were followed up for a mean time of 9 months (range,3-12 months) without recurrence of tumors.The platelet (PLT) of 37 patients was different levels of increasing.Of 21 patients with PLT ＞ 500 × 109/L,PLT was returned to normal range after aspirin and/ or clopidogrel were taken orally.Conclusion LDP with LS is safe and feasible for malignant tumors in the body and tail of pancreas.
