Pancreatic cancer still represents a serious medical concern for which no adequate solution has thus far been found. Surgical resection, when possible, remains the primary treatment modality and can result in long-term cure. The value of more radical resection remains open to debate, despite the negative results of some recent randomized trials with standard vs. extended lymphadenectomy. More effective patient selection, more rational resection, and more compositive treatment should be emphasized in management strategies. In the future, appropriately designed randomized trials of standard vs. extended resections may confirm the benefit of extended surgical resections. In addition, well powered trials of adjuvant therapies strategies together with surgical resections may identify more effective combinations, which may improve the survival of patients with pancreatic cancer.

BACKGROUNDDistal pancreatectomy traditionally included splenectomy; the spleen, however, is an important organ in the immunologic defense of the host and is worthy of preservation. The aim of this research was to study the feasibility, safety and clinical effects of spleen and splenic vessel-preserving distal pancreatectomy.

METHODSA retrospective review was performed for 26 patients undergoing distal pancreatectomy for benign or low grade malignant disease with splenectomy (n = 13) or splenic preservation (n = 13) at the First Hospital of Sun Yat-sen University and Guangdong General Hospital in Southern China from May 2002 to April 2009.

RESULTSAll 26 pancreatectomies with splenectomy or splenic preservation were performed successfully. There was no statistically significant difference between two groups in mean operative time ((172 ± 47) minutes vs. (157 ± 52) minutes, P > 0.05), intraoperative estimated blood loss ((183 ± 68) ml vs. (160 ± 51) ml, P > 0.05), incidence of noninfectious and infection complication and mean length of postoperative hospital stay ((10.1 ± 2.2) days vs. (12.1 ± 4.6) days, P > 0.05). The platelet counts examined one week after operation were significantly higher in the distal pancreatectomy with splenectomy group than the other group ((37.3 ± 12.8) × 10(9)/L vs. (54.7 ± 13.2) × 10(9)/L, P < 0.05).

CONCLUSIONSSpleen-preserving distal pancreatectomy appears to be a feasible and safe procedure. In selected cases of benign or low-grade malignant disease, spleen-preserving distal pancreatectomy is recommended.

The spleen may be preserved during distal pancreatectomy (DP) for benign disease. The aim of this study was to compare the perioperative and postoperative courses of patients with conventional DP and spleen-preserving distal pancreatectomy (SPDP) for benign lesions or tumors with low-grade malignant potential occurred at the body or tail of the pancreas. A retrospective analysis was performed for the hospital records of all the patients undergoing DP and SPDP between January 1995 and April 2006. One-hundred forty-three patients underwent DP and 37 patients underwent SPDP. There were no significant differences in age, sex, indications of operation, estimated blood loss, operative time, and postoperative hospital stay between the two groups. Pancreatic fistula occurred in 21 (13.3%) patients following DP and in 3 (8.1%) following SPDP without a significant difference (p=0.081). Portal vein thrombosis occurred in 4 patients after DP. Splenic infarction occurred in one patient after SPDP. Overwhelming postosplenectomy infection was observed in one patient after DP. SPDP can be achieved with no increase in complication rate, operative time, or length of postoperative hospitalization as compared to conventional DP. Additionally, it has the advantage of reducing the risk of overwhelming postsplenectomy infection and postoperative venous thrombosis.

OBJECTIVETo analyze the indication and choice of operation technique for duodenum-preserving resection of pancreatic head.

METHODSThe Clinical material of the 22 patients who received duodenum-preserving resection of pancreatic head (DPPHR) from January 2001 to January 2006 was analyzed. Of the 22 cases, 8 cases presented with mucinous cystadenoma, 2 cases with mucinous cystadenocarcinoma, 4 cases with solid-pseudopapillary tumors, 2 cases with pancreatic endocrine tumors, 4 cases with chronic pancreatitis, 1 case with lymph epidermis cyst, 1 case with serous cystadenoma. The indication, choice of operation technique of DPPHR and the prevention and management of the post-operative complications were investigated.

RESULTSNo patient died of the operation. Three cases (13.6%) developed pancreatic fistula after the operation, 1 case (4.5%) developed biliary fistula, 1 case (4.5%) developed abdominal infection and 2 cases of duodenal fistula occurred (9.1%).

CONCLUSIONSDPPHR retains the continuity of stomach, duodenum and biliary ducts. The operation is safe and it reduces wounds and excision scope. This procedure can be used in benign and low malignant lesions in the head and neck of the pancreas.

OBJECTIVETo evaluate the clinical outcome of 21 cases of total pancreatectomy.

METHODSThe clinical data of 21 cases of total pancreatectomy performed from April 2003 to June 2006 was retrospectively analyzed.

RESULTSAmong the 21 patients, 1 case combined with transverse colon resection, 1 case with total gastrectomy, 9 cases with portal-superior mesentery vein resection with end-to-end anastomosis, 9 cases with portal-superior mesentery vein resection and grafts implantation, 8 cases with concomitant celiac axis resection, 4 cases with concomitant celiac axis and common hepatic artery resection, 1 case with concomitant celiac axis, portal vein and superior mesentery artery resection and reconstruction. Complications occurred in 12 cases (57.1%) post the operation and 5 cases (23.8%) died in 30 days after the operation. Insulin was given at the dose of 18 - 28 U daily post operation and blood glucose was maintained normal effectively. Sixteen cases were followed-up and median survival was 9.2 months (1.2 - 13.0 months). The median survival of tubular adenocarcinoma and intraductal papillary mucinous neoplasms of the pancreas (IPMNs) were 7 months (1.2 - 9.0 months) and 11.3 months (10.0 - 13.0 months), respectively.

CONCLUSIONSTotal pancreatectomy could not improve survival and it increases the complications and death, but it could improve the quality of life. It's an operation of choice for IPMNs, but with pancreatic carcinoma, the warranty of operation should be considered. The blood glucose level could be maintained normal effectively after the operation.

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

OBJECTIVETo determine the influence of hand-sewn and stapler in distal pancreatectomy on the postoperative complication.

METHODSClinical data of 109 patients after distal pancreatectomy from January 2003 to December 2006 were analyzed retrospectively.

RESULTSThe surgical techniques used for closure of the pancreatic stump after distal pancreatectomy were categorized into hand-sewn closure group (n = 53) and stapler closure group (n = 56). In stapler closure group, 25 patients accepted laparoscopic operation. The incidences of abdominal infection and pancreatic fistulae in stapler closure group were lower than hand-sewn closure group. The operation time, blood infusion, postoperative bleeding and medical costs were similar between two groups.

CONCLUSIONStapler closure in distal pancreatectomy could decrease the incidence of pancreatic fistula and abdominal infections.

OBJECTIVETo analyze the influence of pancreatic fistula in middle segmental pancreatic resection and summarize the experience in dealing with the stump.

METHODSThe data of 40 cases undergoing middle pancreatectomy were reviewed retrospectively to analyze the curative effect and pancreatic fistula between April 2003 and December 2009. Of these, 36 patients with benign cases outcomes were compared with 2 separate control groups, 44 pancreaticoduodenectomy (PD) and 26 extended distal pancreatectomy (EDP).

RESULTSThe mean operating time of group MSP was 222 min, which was significantly shorter than that of group PD. The mean blood loss of group MSP was 316 ml, which was less than that of others. Otherwise, the postoperative nutritional status and blood sugar control in group MSP was superior to the other 2 groups. Through long-term follow-up, the patients in group MSP retained endocrine and exocrine function better. Only 1 patient developed new-onset diabetes mellitus after operation, and no patient required enzyme substitution. No lesion recurred. The rate of pancreatic fistula was highest (42%), but didn't result in the significant deference of overall discharge time with group PD and EDP. The pancreatic fistula level and the mean postoperative time in hospital didn't differ significantly from the other 2 groups.

CONCLUSIONSMiddle segmental pancreatectomy is a safe and feasible technique that is indicated for selected patients with benign or low malignant lesion in the neck and body of the pancreas. Though the rate of pancreatic fistula is higher, the risk of which is reduced by the marked curative effect. It is very important to deal with the stump reasonably.

OBJECTIVETo study the application of three-dimensional visualization technology for laparoscopic resection of cystic carcinoma in the pancreatic body and tail.

METHODSSix cases of cystic carcinoma in the pancreatic body and tail treated between Nov, 2009 and Mar, 2011 were retrospectively analyzed. The original image data of 64-slice spiral CT were collected and using adaptive region growing algorithm, the serial CT images were segmented and automatically extracted to obtain the 3-dimensional reconstruction images with customized image manipulation software. The specific surgical approach (the trocar position) and surgical procedure were planned based on the reconstructed mode.

RESULTSThe reconstructed 3-dimensional model clearly displayed cystic carcinoma in the pancreatic body and tail and the adjacent organs, showing distinct relationship between the cystoma and the splenic artery and vein. All the patients successfully underwent laparoscopic resection of the pancreatic body and tail without perioperative death. The spleen was preserved in 5 cases and removed in 1 case due to mucinous cystadenocarcinoma. The overall rate of pancreatic fistulae was 33.3% without incidences of postoperative hemorrhage. The average hospital stay of the patients was 12 days.

CONCLUSIONThree-dimensional reconstruction based on pancreatic CT data provides valuable assistance for laparoscopic resection of cystic carcinoma in the pancreatic body and tail.
