RESUMO
BACKGROUND: Laparoscopic distal pancreatectomy (LDP) showed advantage of perioperation outcomes for benign and low-grade tumor of the pancreas. The application of LDP for pancreatic ductal adenocarcinoma (PDAC) didn't gain popular acceptance and the number of LDP for PDAC remains low. We designed a case-matched study to analysis the short- and long-term outcomes of the patients undergoing either Laparoscopic distal pancreatectomy or open distal pancreatectomy for PDAC. METHOD: From 2003 to 2013, 17 patients were underwent LDP and 34 patients were underwent ODP for PDAC were matched by tumor size, age and body mass index (BMI). The two groups' demographic information, perioperative outcomes and survival data were compared. RESULTS: Baseline characteristics were comparable between the LDP and ODP groups. The intraoperative blood loss, first flatus, first oral intake and postoperative hospital stay were significantly less in LDP group than ODP group (50 ml vs400ml, P = 0.000; 3d vs 4d, P = 0.001; 3d vs 4d, P = 0.003; 13d vs 15.5d, P = 0.022). The mean operation time, overall postoperative morbidity and postoperative pancreatic fistula rates were similar in the two groups. 5 patients (29.4 %) in LDP group and 7 patients (20.6 %) in ODP group underwent extended resections. There were no significant differences in tumor sizes (3.5 cm vs 3.9 cm, P = 0.664) and number of harvested lymph nodes (9 vs8 P = 0.534). The median overall survival for both groups was 14.0 months. Cox proportional hazards analysis showed extended resections, R1 resection, perineural invasion and tumor differentiation were associated with worse survival. CONCLUSION: LDP is technically feasible and safe for PDAC in selected patients and the short-term oncologic outcomes were not inferior to ODP in this small sample study. However the long-term oncologic safety of LDP for PDAC has to be further evaluated by multicenter or randomized controlled trials.

OBJECTIVE: To evaluate the safety and efficacy of laparoscopic resection for gastrointestinal stromal tumors (GISTs) of the stomach with systematic review and meta-analysis. METHODS: The literature database before March, 2014 was extensively searched to retrieve the comparative studies of laparoscopic (LAP) and open resection (OPEN) for GISTs with a relevance of study goal. The inclusion and exclusion criteria were formulated. After a quality evaluation, the data were extracted. The Cochrane collaboration RevMan5.1 version software was used for meta-analysis. RESULTS: There are nineteen studies meeting the inclusion criteria for meta-analysis. The total sample size of these studies was 1,060 cases. The operation time was similar between the two groups [weighted mean difference (WMD) -7.20 min, 95 % confidence interval (CI) -25.65 to 11.25, P = 0.44)]. Compared to OPEN, however, LAP experienced less blood loss (WMD -54.21 ml, 95 % CI -82.65 to -25.77, P < 0.01), earlier time to flatus (WMD -1.34 days, 95 % CI -1.62 to -1.06, P < 0.01) and oral diet (WMD -1.80 days, 95 % CI -2.18 to -1.42, P < 0.01), shorter hospital stay (WMD -3.68 days, 95 % CI -4.52 to -2.85, P < 0.01) and decrease in overall complications [relative risk (RR) 0.51, 95 % CI 0.32-0.80, P < 0.01)]. In addition, the long-term follow-up result shows that there is no significant difference in the two groups of patients. CONCLUSION: Laparoscopic resection for gastric GISTs is a safe and feasible procedure with less blood loss, less overall complications and quicker recovery. The long-term survival situation of patients mainly depends on the tumor itself risk, and laparoscopic surgery will not increase the risks of tumor relapse and metastasis.

Some laterally advanced cholangiocarcinomas behave as ductal spread or local invasion, and hepatopancreatoduodenectomy (HPD) may be performed for R0 resection. To date, there have been no reports of laparoscopic HPD (LHPD) in the English literature. We report the first case of LHPD for the resection of a Bismuth IIIa cholangiocarcinoma invading the duodenum. The patient underwent laparoscopic pancreaticoduodenectomy and right hemihepatectomy. Child's approach was used for the reconstruction. The patient recovered well with bile leakage from the 2(nd) postoperative day and was discharged on the 16(th) postoperative day with a drainage tube in place which was removed 2 wk after discharge. Postoperative pathology revealed a well-differentiated cholangiocarcinoma and the margin of liver parenchyma, pancreas and stomach was negative for metastases. The results suggest that LHPD is a feasible and safe procedure when performed in highly specialized centers and in suitable patients with cholangiocarcinoma.

Mixed mucinous cystadenoma with serous cystadenoma of the pancreas is rare. There have been only two previous case reports in the English-language literature. We present a case of a 46-year-old woman who was diagnosed with mixed mucinous cystadenoma with serous cystadenoma of the pancreas. Computed tomography and magnetic resonance imaging showed a cystic neoplasm in the dorsal/proximal body of the pancreas with a clear-margin multilocular cavity and enhanced internal septum. The patient underwent laparoscopic central pancreatectomy. The diagnosis of mixed mucinous cystadenoma with serous cystadenoma of the pancreas was confirmed by pathological examination. The patient was followed up for 3 months and there were no signs of recurrence, or pancreatic exocrine or endocrine insufficiency. To the best of our knowledge, this is the first reported case treated by laparoscopic central pancreatectomy.

Gastric adenosquamous carcinoma (ASC) is a rare type of gastric cancer. It is a mixed neoplasm, consisting of glandular cells and squamous cells. It is often diagnosed at an advanced stage, thus carrying a poor prognosis. We describe a case of a 73-year-old male, who presented with refractory fever and an intra-abdominal mass on imaging. He underwent a laparoscopic exploration followed by a successful totally laparoscopic total gastrectomy with D2 lymphadenectomy for gastric cancer. Postoperative pathology revealed primary gastric ASC (T4aN0M0). The patient received adjuvant radiotherapy and chemotherapy with S1 and is alive 20 mo after surgery without recurrence. This is the first case of advanced gastric ASC with fever as the initial presentation treated with totally laparoscopic total gastrectomy reported in the English literature.

Splenic artery aneurysm is one of the most common visceral aneurysms, and patients with this type of aneurysm often present without symptoms. However, when rupture occurs, it can be a catastrophic event. Although most of these aneurysms can be treated with percutaneous embolization, some located in uncommon parts of the splenic artery may make this approach impossible. We present a patient with an aneurysm in the proximal splenic artery, close to the celiac trunk, which was treated by laparoscopic ligation only, without resection of the aneurysm, and with long-term preservation of splenic function.

AIM: To compare short- and long-term outcomes of laparoscopic vs open distal pancreatectomy for solid pseudopapillary tumor (SPT) of the pancreas. METHODS: This retrospective study included 28 patients who underwent distal pancreatectomy for SPT of the pancreas between 1998 and 2012. The patients were divided into two groups based on the surgical approach: the laparoscopic surgery group and the open surgery group. The patients' demographic data, operative results, pathological reports, hospital courses, morbidity and mortality, and follow-up data were compared between the two groups. RESULTS: Fifteen patients with SPT of the pancreas underwent laparoscopic distal pancreatectomy (LDP), and 13 underwent open distal pancreatectomy (ODP). Baseline characteristics were similar between the two groups except for a female predominance in the LDP group (100.0% vs 69.2%, P = 0.035). Mortality, morbidity (33.3% vs 38.5%, P = 1.000), pancreatic fistula rates (26.7% vs 30.8%, P = 0.728), and reoperation rates (0.0% vs 7.7%, P = 0.464) were similar in the two groups. There were no significant differences in the operating time (171 min vs 178 min, P = 0.755) between the two groups. The intraoperative blood loss (149 mL vs 580 mL, P = 0.002), transfusion requirement (6.7% vs 46.2%, P = 0.029), first flatus time (1.9 d vs 3.5 d, P = 0.000), diet start time (2.3 d vs 4.9 d, P = 0.000), and postoperative hospital stay (8.1 d vs 12.8 d, P = 0.029) were significantly less in the LDP group than in the ODP group. All patients had negative surgical margins at final pathology. There were no significant differences in number of lymph nodes harvested (4.6 vs 6.4, P = 0.549) between the two groups. The median follow-up was 33 (3-100) mo for the LDP group and 45 (17-127) mo for the ODP group. All patients were alive with one recurrence. CONCLUSION: LDP for SPT has short-term benefits compared with ODP. Long-term outcomes of LDP are similar to those of ODP.

BACKGROUND: Central pancreatectomy has been accepted as an alternative procedure for treating benign or low-grade malignant tumors in the pancreatic neck or proximal body of the pancreas, which preserves pancreatic parenchyma and function. In this study, we present our experience of laparoscopic central pancreatectomy with pancreaticojejunostomy. PATIENTS AND METHODS: From April 2011 to February 2013, 8 patients underwent laparoscopic central pancreatectomy with a Roux-en-Y modified "dunking" or duct-to-mucosa pancreaticojejunostomy for benign or low-grade malignant tumors in the pancreatic neck or proximal body of the pancreas at the Department of General Surgery, Sir Run Run Shaw Hospital, Hangzhou, China. Surgical procedure, postoperative course, and follow-up data were collected. RESULTS: Laparoscopic central pancreatectomy was performed successfully in all the patients. The pancreaticojejunostomy was executed with a modified "dunking" pancreaticojejunostomy (n=7) or duct-to-mucosa pancreaticojejunostomy (n=1). The mean operative time was 286±27 minutes (range, 250-330 minutes), with a mean blood loss of 57±21 mL (range, 30-100 mL). Mortality was 0%, and perioperative morbidity was 37.5% (pancreatic fistula [grade A], bleeding of a splenic vein branch, and retroperitoneal infection). The median postoperative hospital stay was 10 days (range, 6-38 days). At a median follow-up of 7.5 months (range, 2-24 months), all patients were alive without any exocrine or endocrine insufficiency or recurrence. CONCLUSIONS: Laparoscopic central pancreatectomy is feasible and safe. The modified "dunking" pancreaticojejunostomy can be performed safely in this approach.

Studies on laparoscopic transduodenal local resection have not been readily available. Only three cases have been reported in the English-language literature. We describe herein a case of 25-year-old woman with periampullary neuroendocrine tumor (NET). Endoscopic ultrasonography revealed a duodenal papilla mass originated from the submucosa and close to the ampulla. The periampullary tumor was successfully managed with laparoscopic transduodenal local resection without any procedure-related complications. Pathological examination showed a NET (Grade 2) with negative margin. The patient was followed up for six months without signs of recurrence. This case suggests that laparoscopic transduodenal local resection is a feasible procedure in selected patients with periampullary tumor.
