| 1 | Laparoscopic vs open distal pancreatectomy for solid pseudopapillary tumor of the pancreas显示文摘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(1.9d 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 12.8d,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 vs6.4,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. | Ren-Chao Zhang Jia-Fei Yan Xiao-Wu Xu Ke Chen Harsha Ajoodhea Yi-Ping Mou | 2013 | World Journal of Gastroenterology2013，19，37： | 14 |
| 2 | Resection of a cholangiocarcinoma via laparoscopic hepatopancreato- duodenectomy:A case report显示文摘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 BismuthⅢa 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 2nd postoperative day and was discharged on the 16th postoperative day with a drainage tube in place which was removed 2 wk after discharge.Postoperative pathology revealed a well-differentiated cholangiocarcinoma andthe 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. | Miao-Zun Zhang Xiao-Wu Xu Yi-Ping Mou Jia-Fei Yan Yi-Ping Zhu Ren-Chao Zhang Yu-Cheng Zhou Ke Chen Wei-Wei Jin Erik Matro Harsha Ajoodhea | 2014 | World Journal of Gastroenterology2014，20，45： | 12 |
| 3 | Laparoscopic spleen-preserving distal pancreatectomy for pancreatic neoplasms:A retrospective study显示文摘AIM:To describe the clinical characteristics,technical procedures,and outcomes of patients undergoing laparoscopic spleen-preserving distal pancreatectomy(LSPDP)for benign and malignant pancreatic neoplasms.METHODS:The clinical data of 38 patients who underwent LSPDP in the Sir Run Run Shaw Hospital between January 2003 and August 2013 were analyzed retrospectively.Surgical techniques for LSPDP included preservation of the splenic artery and vein(Kimura’s technique)and ligation of the splenic pedicle with preservation of the short gastric vessels(Warshaw’s technique).RESULTS:There were no conversions to open surgery in the 38 patients.Splenic vessels were conserved during spleen-preserving pancreatectomy,except in two patients who underwent resection of the splenic vessels and preservation only of the short gastric vessels.The mean operation time was 123.2±52.4 min,the mean intraoperative blood loss was 78.2±39.5 mL,and the mean postoperative hospital stay was 7.6±2.9 d.The overall rate of postoperative complications was 18.4%(7/38),and the rate of clinical pancreatic fistula was13.2%(5/38).All postoperative complications were treated conservatively.The postoperative pathological diagnoses were 22 cases of benign pancreatic disease and 16 cases of borderline or low-grade malignant lesions.During a median follow-up of 38 mo(range:5-133mo),no recurrence was observed.CONCLUSION:LSPDP is a safe,feasible and effective procedure for the treatment of benign and low-grade malignant tumors of the distal pancreas. | Jia-Fei Yan Xiao-Wu Xu Wei-Wei Jin Chao-Jie Huang Ke Chen Ren-Chao Zhang Ajoodhea Harsha Yi-Ping Mou | 2014 | World Journal of Gastroenterology2014，20，38： | 11 |
| 4 | Laparoscopic ligation of proximal splenic artery aneurysm with splenic function preservation显示文摘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. | Yun-Hai Wei Jie-Wei Xu Hua-Ping Shen Guo-Lei Zhang Harsha Ajoodhea Ren-Chao Zhang Yi-Ping Mou | 2014 | World Journal of Gastroenterology2014，20，16： | 7 |
| 5 | Fever as a first manifestation of advanced gastric adenosquamous carcinoma:A case report显示文摘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 20mo 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. | Harsha Ajoodhea Ren-Chao Zhang Xiao-Wu Xu Wei-Wei Jin Ke Chen Yong-Tao He Yi-Ping Mou | 2014 | World Journal of Gastroenterology2014，20，29： | 6 |
| 6 | Laparoscopic transduodenal local resection of periampullary neuroendocrine tumor: A case report显示文摘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. | Ren-Chao Zhang Xiao-Wu Xu Di Wu Yu-Cheng Zhou Harsha Ajoodhea Ke Chen Yi-Ping Mou | 2013 | World Journal of Gastroenterology2013，19，39： | 3 |
