Objective To compare the survival conditions of patients with insulinoma after enucleation of insulinoma or partial resection of pancreas.Methods The clinical data of 99 patients with insulinoma,treated with surgery from May.2003 to Aug.2015 were retrospectively analyzed.Of the 99 patients,38 received enucleation of insulinoma alone and 61 received partial resection of pancreas.The overall data were analyzed by SPSS 21.0 software.Results Average survival of patients after enucleation of insulinoma (103.3 months) was longer than that of patients after partial resection of pancreas (77.5 months),and the difference had statistical significance (P=0.006).The difference of the incidence of most chronic or temporary complications had no statistical significance between the two groups (P＞0.05),except for new-onset diabetes (P=0.004).Conclusion Enucleation of insulinoma should be firstly recommended for patients with insulinoma in suitable size,which can provide patients with better survival condition.

Objective To evaluate surgical therapies for chronic pancreatitis.Method The clinical data of 229 patients admitted for chronic pancreatitis during March 2009 to November 2013 in our hospital was retrospectively analyzed,different operation method and their clinical outcome were compared.Results Drainage operations or resection operations were made to all these 229 patients according to different types.57 patients underwent longitudinal pancreaticojejunostomy (LPJ procedure).118 patients received local resection of the head of pancreas combined with longitudinal pancreaticojejunostomy (Frey procedure in 105 cases,Berne procedure in 6 cases,Beger procedure in 7 cases).7 patients received pancreaticoduodenectomy,21 patients received distal pancreas resection,26 patients received other procedures.Post-operative pain relief rate was 89.3％,overall morbidity was 19.6％.Conclusions In cases of chronic pancreatitis,different surgical types are adopted according to their individual indications.Operation in accordance with pathological types guarantees clinical outcome.

Objective To compare biliary tract intraductal papillary mucinous neoplasm (BT-IPMN) with intraductal papillary mucinous neoplasm of the pancreas (P-IPMN).Methods From January 2008 to December 2013,eleven (6.0％) cases of BT-IPMNs were retrospectively identified from a total of 182 biliary tract tumors resected in our institution,while 50 cases underwent surgery for P-IPMN.The mean age of the 11 BT-IPMN cases was 57.3 years (range 40 to 74 years).There were 8 men (73.0％).The mean age of the 50 P-IPMN cases was 57.4 years (range 33 to 85 years).There were 34 men (68.0％).The clinical features,radiologic findings,pathology,surgical strategies,and long-term follow up outcomes between the 2 groups of patients were analyzed.Results There was no significant difference between BT-IPMN and P-IPMN in the following aspects:mean age,sex ratios and clinical presentation [including the most common presenting symptom abdominal pain (73.0％ vs.68.0％),and elevated tumor markers (CEA and CA19-9)].The mean tumor size of BT-IPMN was significantly smaller than P-IPMN (1.7 vs.4.1 cm,P ＜ 0.05).Macroscopically visible mucin was detected in all the 11 patients basing on the original surgical reports.The most common abnormal preoperative imaging findings for BT-IPMN were bile duct dilatation (100％) and intraluminal masses (55.0％).Most cases (82.0％) involved the intrahepatic bile duct and hilum.For tumor clearance,we conducted left hepatectomy in most cases (64.0％).Only one patient underwent biopsy and choledochojejunostomy for multiple tumors involving the extrahepatic,right and left bile ducts.BT-IPMN was likely to have a higher risk of malignancy (55.0％ vs.44.0％) and poorer prognosis (median survival,57 vs.63 months),although there was no significant difference (P ＞ 0.05).The patient without tumor resection died of liver failure 22 months after palliative surgery.Conclusions BT-IPMNs are very rare and they had some similarity with P-IPMN.Complete resection of BT-IPMN is associated with good survival.

We performed a simultaneous pancreas-kidney transplantation (SPK) for type 2 diabetes complicated with end-staged renal disease (ESRD) in March, 2007. The recipient was a 65-year old male, who suffered type 2 diabetes for 15 years and renal dysfunction for 5 years and other diabetic complications such as retinopathy and peripheral neuropathy. SPK was performed successfully for him, in which the kidney was placed in the left iliac fossa, while the pancreas in the right iliac fossa, with an entedc drainage for pancreas exocrine and a systemic drainage for endocrine. Serum C-peptide, creatinine and blood urea nitrogen reached normal levels on day 1,4 and 11 post-transplant, respectively. Blood glucose became stabilized gradually to normal level and therefore the injected insulin was stopped on day 16 post-transplant. Oral glucose tolerance test (OGTT) showed the function of grafted pancreas was normal after 3 weeks of transplant, and no transplant-related complications occurred. With the recipient followed up for 20 months, both his blood glucose level and renal function maintained normal without using insulin.

Pancreatic cystic neoplasm is a general term for a large class of pancreatic tumors,including mucinous cystic neoplasm,serous cystic neoplasm,and pancreatic intraductal papillary mucinous neoplasm.Due to the limitations of the current techniques in differential diagnosis and disease staging,different centers have great discrepancies in their treatment.The 103rd annual meeting of American College of Surgeons (ACS)as a grand meeting in the field of surgery bringed together a large number of clinical research results every year.Therefore,authors selected and reviewed contents about pancreatic cystic neoplasm,with a view to provide new ideas in terms of its management and further research.

The borderline resectable pancreatic cancer is high a controversial hotspot in the field of pancreatic surgery,and the controversy mainly focuses on definition and treatment.Five famous experts and their teams in pancreatic surgery discussed present situation and dilemmas in treatment of borderline resectable pancreatic cancer based on clinical experiences.Professor Hao Chunyi has reviewed and analyzed origin of the definition and treatment model of borderline resectable pancreatic cancer,and proposed that high-level pancreatic disease center and multidisciplinary collaboration diagnosis and treatment may be the best choice for resectable pancreatic cancer.Professor Liu Xubao suggested surgical treatment for most of borderline resectable pancreatic cancer,and whether or not tumor invades adjacent blood vessels and invasion level will be used to decide direct surgery or neoadjuvant therapy.Professor Sun Bei proposed 6 causes,and direct surgery may be more realistic and feasible option for borderline resectable pancreatic cancer.Professors Liang Tingbo and Bai Xueli recommended that neoadjuvant therapy should be performed due to defeat hiding micrometastasis lesions and reduce tumor burden,and there was a higher R0 resection rate and lower lymph node metastasis rate after neoadjuvant therapy,meanwhile,it can also increase cure rate and is benefited to survival.

Objective:To evaluate the impact of resection margin status within a cut-off 1 mm clearance of cancer on the groove of portal/superior mesenteric vein and/or the top end of the uncinate process bordering on the superior mesenteric artery in pancreatic head adenocarcinoma patients after pancreatoduodenectomy.Methods:The clinical, pathological and followup data of 113 pancreatic head adenocarcinoma patients undergoing pancreatoduodenectomy with or without vascular graft replacement were retrospectively analyzed.Results:Univariate analysis showed that resection margin 1mm clearance, postoperative adjuvant chemotherapy, T staging, N staging, TNM staging (AJCC), gender, and maximum tumor diameter were risk factors for survival . Multivariate analysis showed that surgical margin 1mm clearance, postoperative adjuvant chemotherapy, and gender were independent prognostic factors. In resection margin >1 mm group(83 cases), the mean survival time was 19.04 months, and the 1-year, 2-year, and 3-year survival rates were 78%, 50%, and 25%, respectively. In resection margin ≤1 mm group(30 cases), the mean survival time was 9.42 months, and the 1-year, 2-year and 3-year survival rates were 61%, 20% and 0, respectively. There was statistical significance between the two groups in survival time ( P=0.018). Conclusion:Resection margins 1 mm clearance of cancer off portal vein/superior mesenteric vein and superior mesenteric artery is independent prognostic factors in pancreatic head adenocarcinoma patients undergoing pancreatoduodenectomy.
