Articles published in English from January 1, 1995 to June, 30 2016 that met the selection criteria were retrieved and reviewed. The Preferred Reporting Items for Systematic reviews and Meta-Analysis(PRISMA) statements checklist for reporting a systematic review was followed. Random-effect models were used to estimate mean differences and risk ratios. The robustness and heterogeneity of the results were explored by performing sensitivity analyses. The pooledeffect was considered significant when P < 0.05.RESULTS Overall, 14 RCTs were included. No differences were found in postoperative mortality(P = 0.19) and morbidity(P = 0.75) rates. The mean operative time was 36.67 min longer(95%CI: 27.22-46.11, P < 0.00001), the mean estimated blood loss was 88.80 ml lower(95%CI:-117.25 to-60.34, P < 0.00001), and the mean incision length was 11.17 cm smaller(95%CI:-13.88 to-8.47, P < 0.00001) for LRR than ORR. These results were confirmed by sensitivity analyses that focused on the four major RCTs. The mean length of hospital stay was 1.71 d shorter(95%CI:-2.84 to-0.58, P < 0.003) for LRR than ORR. Similarly, bowel recovery(i.e., day of the first bowel movement) was 0.68 d shorter(95%CI:-1.00 to-0.36, P < 0.00001) for LRR. The sensitivity analysis did not confirm a significant difference between LRR and ORR for these latter two parameters. The overall quality of the evidence was rated as high. CONCLUSION LRR is associated with lesser blood loss, smaller incision length, and longer operative times compared to ORR. No differences are observed for postoperative morbidity and mortality.展开更多

Laparoscopic resection of uterine mass lesion is rarely used in gestational choriocarcinoma diagnosis because of the fear of heavy blood loss and distant metastasis. Five patients who were preoperatively diagnosed as having cornual pregnancy underwent laparoscopic resection of mass lesion and then proved to have gestational choriocarcinoma based on pathological examinations. Chemotherapy was started within two days after surgery, and the rate of complete remission was 100%. The mean follow-up time was 29.8±19.1 months, and no patient showed signs of relapse. Laparoscopic resection of uterine mass followed by timely postoperative chemotherapy may be an effective and safe way to obtain pathologic results in patients with suspected gestational choriocarcinoma.展开更多

Recently, an increasing incidence of synchronous DPLC has been reported, while the diagnostic standard and treatment strategies remain to be improved. This study was conducted to investigate effective surgical treatment and prognosis of synchronous DPLC. METHODS From January 1983 to April 2004, 31 patients with synchronous DPLC were operated in our department. Clinical data, such as surgical pattern, postoperative complications, and survival status, of all these patients were reviewed retrospectively. RESULTS The 31 patients with synchronous DPLC accounted for 0.67% of all the 4,649 patients operated for primary lung cancer in our department during the same period. Both tumors of the synchronous DPLC were resected with Iobectomy or pneumonectomy in 12 patients, while among the other 19 patients at least 1 tumor was treated with partial pulmonary resection. The postoperative morbidity was 29%（9/31）, including 1 case of respiratory insufficiency, 3 cases of atelectasis, 2 cases of atrial fibrillation, 1 case of haemoptysis, 1 case of pleural effusion, and 1 case of wound fat necrosis. No deaths occurred during the operations or within 30 days postoperatively. The postoperative 1 -, 3-, and 5-year survival rates were 52%, 29%, and 20%, respectively. CONCLUSION The incidence of synchronous DPLC is low. An aggressive and reasonable surgical approach can achieve a satisfactory outcome in patients with synchronous DPLC. The postoperative morbidity is low. Some patients might achieve long-term survival.展开更多

Early detection and accurate preoperative staging of gastric cancer is essential for planning optimal therapy such as endoscopic mucosal resection or gastric resection and offers the best prognosis. With advanced technology in diagnostic instruments and the mass screening, early gastric cancer has been detected easier. One-point cancer of gastric is a special type of early gastric cancer. Diagnosis of one-point cancer of gastric is important for both the immediate treatment and the prognosis. There is still no consensus on the operation extent and postoperative treatment for patients with one-point cancer of gastric. Learned from previous reports, we know that existed in the superficial layer of the gastric mucosa and the superficial ulcer is one of the important characteristics of one point cancer of gastric. Herein, we report a case of one point cancer of gastric with the appearance of a deep infiltrating ulcer. To the best of our knowledge, no such type of one point cancer of gastric has been reported.展开更多
