Laparoscopic Versus Open Resection of Small Bowel Gastrointestinal Stromal Tumors: Systematic Review and Meta-Analysis / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Laparoscopic resection (LAP) for small bowel gastrointestinal stromal tumors (GISTs) is not as common as for stomach. This study aimed to evaluate the safety and efficacy of LAP for small bowel GISTs with systematic review and meta-analysis.</p><p><b>METHODS</b>The Web of Science, Cochrane Library, Embase, and PubMed databases before December 2016 were comprehensively searched to retrieve comparative trials of LAP and conventional open resection (OPEN) for GISTs of small bowel with a relevance of review object. These researches reported intraoperative and postoperative clinical course (operation time, blood loss, time to first flatus and oral intake, hospital stay, morbidity, and mortality), oncologic outcomes, and long-term survival status.</p><p><b>RESULTS</b>Six studies involving 391 patients were identified. Compared to OPEN, LAP had associated with a shorter operation time (weighted mean difference [WMD] = -27.97 min, 95% confidence interval [CI]: -49.40--6.54, P < 0.01); less intraoperative blood loss (WMD = -0.72 ml; 95% CI: -1.30--0.13, P = 0.02); earlier time to flatus (WMD = -0.83 day; 95% CI: -1.44--0.22, P < 0.01); earlier time to restart oral intake (WMD = -1.95 days; 95% CI: -3.31--0.60, P < 0.01); shorter hospital stay (WMD = -3.00 days; 95% CI: -4.87--1.13, P < 0.01); and a decrease in overall complications (risk ratio = 0.56, 95% CI: 0.33-0.97, P = 0.04). In addition, the tumor recurrence and long-term survival rate showed that there was no significant difference between the two groups of patients.</p><p><b>CONCLUSIONS</b>LAP for small bowel GISTs is a safe and feasible procedure with shorter operation time, less blood loss, less overall complications, and quicker recovery. Besides, tumor recurrence and the long-term survival rate are similar to open approach. Because of the limitations of this study, methodologically high-quality studies are needed for certain appraisal.</p>

Laparoscopic anti-reflux surgery with biological mesh in treatment of gastroesophageal reflux disease / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To evaluate the application of biological mesh in laparoscopic anti-reflux procedure for gastroesophageal reflux disease (GERD).</p><p><b>METHODS</b>The clinical data of 20 consecutive GERD patients underwent anti-reflux surgery in Sir Run Run Shaw Hospital from December 2012 to April 2014 were retrospectively analyzed. The laparoscopic hiatal repair with 360 fundoplicaiton was performed and the biological mesh (BiodesignTM, Surgsis) was implanted for reinforcement of hiatal repair.</p><p><b>RESULTS</b>All laparoscopic procedures were successful, no conversion and no intra-operative complications occurred. The pre-operative complains were relieved in all patients, and no recurrence was observed during 3-18 month of follow-up. Six patients got dysphagia after operation; 5 of them were controlled through medication and psychological induction; 1 received esophageal dilatation by bougie.</p><p><b>CONCLUSION</b>The application of biological mesh in laparoscopic anti-reflux procedure for gastroesophageal reflux disease is satisfactory.</p>

Immediate breast reconstruction using laparoscopically harvested omental flap after breast-conserving surgery / 中华整形外科杂志

<p><b>OBJECTIVE</b>To report our primary experience with immediate breast reconstruction using laparoscopically harvested omental flap after breast-conserving surgery. The safety, feasibility, and clinical effect are also evaluated.</p><p><b>METHODS</b>From Jun. 2010 to Jan. 2011, 5 cases who underwent immediate breast reconstruction using laparoscopically harvested omental flap after breast-conserving surgery were retrospectively analyzed. The operative duration, postoperative days in hospital, complication and therapeutic effect were reviewed.</p><p><b>RESULTS</b>All the patients were treated successfully without laparotomy. The average operative duration was 310 min, including 60 min for harvesting the omental flap. The median postoperative days in hospital was 8 days (ranged, 5-9 days). One case complained of slight pulled feeling in upper abdomen. No other complication happened. The cosmetic result of reconstructed breasts was satisfactory.</p><p><b>CONCLUSIONS</b>The immediate breast reconstruction using laparoscopically harvested omental flap is safe and feasible with less morbidity in donor sites and good cosmetic effect. It is one of the ideal methods for immediate breast reconstruction.</p>

Massive gastrointestinal bleeding from Meckel diverticulum with ectopic pancreatic tissue / 中华医学杂志(英文版)

Meckel diverticulum (MD), a congenital gastrointestinal anomaly, is often involved in pediatrics, but less in the adult population. The patient in this report was a 69-year-old female presented with massive gastrointestinal bleeding causing hemorrhagic shock due to MD containing ectopic pancreatic tissue. A review of the literature revealed that gastrointestinal bleeding from MD containing ectopic pancreatic tissue is rare in adults and difficult to be identified preoperation. MD should be considered as one of the differential diagnosis for lower gastrointestinal bleeding, although scarce in adults, especially when the patient has massive painless bleeding.

Multivariable analysis of factors associated with hospital readmission following pancreaticoduodenectomy for malignant diseases / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Readmission rates after pancreaticoduodenectomy (PD) for malignant diseases have a significant impact on survival rate. Identification of risk factors for readmission may improve discharge plans and postoperative care. Data exist on the morbidity and mortality of patients undergoing PD, but there are few reports about hospital readmissions after this procedure. Our aims were to evaluate the proportion and reasons for readmissions after PD for malignant diseases, the factors influencing readmissions, and to analyze the relationship between readmission rate and survival rate.</p><p><b>METHODS</b>Four hundred and thirty-six patients, who had undergone PD for malignant diseases in our centre from October 1999 to October 2009, a 10-year period, excluding perioperative (30-day) mortality, were identified. All readmissions within 1 year following PD were analyzed with respect to timing, location, reasons for readmission and outcome. We reviewed the hospitalization and readmissions for patients undergoing PD, and compared patients requiring readmission to patients that did not require readmission.</p><p><b>RESULTS</b>One hundred and forty-five patients (33.26%) were readmitted within 1 year following PD, for further treatment or complications. In those cases, diagnoses associated with high rates of readmission included radiation and/or chemotherapy (48.96%), progression of disease (11.72%), infection (11.72%), gastrointestinal dysfunction/obstruction (6.20%), surgery-related complications (2.76%) and pain (4.14%). The proportion of T4 in readmission group was lower than no readmission group (P < 0.05). The proportion of node positive cases in readmission group was much higher than no readmission group (P < 0.01). The number of readmission for complications reduced gradually in the first three months, and reached a second peak in the sixth and seventh month. Median survival was lower for the readmission group compared with the no readmission group (21 versus 46 months, P = 0.024).</p><p><b>CONCLUSION</b>These results may assist in both anticipating and facilitating postoperative care as well as managing patient expectations.</p>
