    ABSTRACT: To evaluate the 5-year survival after laparoscopic surgery vs open surgery for stages II and III rectal cancer. This study enrolled 406 consecutive patients who underwent curative resection for stages II and III rectal cancer between January 2000 and December 2009 [laparoscopic rectal resection (LRR), n = 152; open rectal resection (ORR), n = 254]. Clinical characteristics, operative outcomes, pathological outcomes, postoperative recovery, and 5-year survival outcomes were compared between the two groups. Most of the clinical characteristics were similar except age (59 years vs 55 years, P = 0.033) between the LRR group and ORR group. The proportion of anterior resection was higher in the LRR group than that in the ORR group (81.6% vs 66.1%, P = 0.001). The LRR group had less estimated blood loss (50 mL vs 200 mL, P < 0.001) and a lower rate of blood transfusion (4.6% vs 11.8%, P = 0.019) compared to the ORR group. The pathological outcomes of the two groups were comparable. The LRR group was associated with faster recovery of bowel function (2.8 d vs 3.7 d, P < 0.001) and shorter postoperative hospital stay (11.7 d vs 13.7 d, P < 0.001). The median follow-up time was 63 mo in the LRR group and 65 mo in the ORR group. As for the survival outcomes, the 5-year local recurrence rate (16.0% vs 16.4%, P = 0.753), 5-year disease-free survival (DFS) rate (63.0% vs 63.1%, P = 0.589), and 5-year overall survival (OS) rate (68.1% vs 63.5%, P = 0.682) were comparable between the LRR group and the ORR group. Stage by stage, there were also no statistical differences between the LRR group and the ORR group in terms of the 5-year local recurrence rate (stage II: 6.3% vs 8.7%, P = 0.623; stage III: 26.4% vs 23.2%, P = 0.747), 5-year DFS rate (stage II: 77.5% vs 77.6%, P = 0.462; stage III: 46.5% vs 50.9%, P = 0.738), and 5-year OS rate (stage II: 81.4% vs 74.3%, P = 0.242; stage III: 53.9% vs 54.1%, P = 0.459). LRR for stages II and III rectal cancer can yield comparable long-term survival while achieving short-term benefits compared to open surgery.

    ABSTRACT: At present, surgery has become one of the treatments for type 2 diabetes, but it is still unclear about the therapeutic mechanism. Many experiments has proved that the anatomical and physiological structure has been altered leading to significant changes related to the secretion of gastrointestinal hormones and neuropeptides. These molecular are related to the metabolism of glucose, functions of islet cells and sensitivity of insulin. Intensive studies of glucagon-like peptide-1(GLP-1) play an important role in the surgical treatment of diabetes and now it has gained increasing recognition. However, GLP-1 must be combined with GLP-1 receptor(GLP-1R) to execute its function. In this paper we reviewed the role of GLP-1 and its receptor in the mechanism of metabolic surgery.

    ABSTRACT: To investigate the efficacy and feasibility of duodenojejunal bypass(DJB)on non-severe obese patients with type 2 diabetes mellitus(T2DM). The body mass index (BMI), fasting plasma glucose(FPG), 2h-postprandial plasma glucose(2hPG), fasting insulin(F-ins), fasting c-peptide(F-CP), glycated hemoglobin and hypoglycemic agents dose changes were tested in 7 patients with non-severe obese T2DM undergoing DJB, preoperatively and within 24 weeks after surgery during the follow-up. Data were collected and the clinical outcomes of T2DM were analyzed. In 7 cases of non-obese T2DM who underwent DJB, one patient was weaned off hypoglycemic agents with normal FPG, 2hPG and HbA1c postoperatively. Five required significantly lower dosage. No significant improvement in 1 case. Complete remission rate of hyperglycemia was 1/7, effective rate was 6/7, and effective rate of HbA1c was 5/7. No significant changes in BMI were observed between the preoperative and postoperative phases. Plasma glucose level can be markedly reduced by duodenojejunal bypass in non-obese T2DM, independent of weight loss, and the mechanism remains unclear.

    ABSTRACT: To explore the feasibility and therapeutic effect of total laparoscopic left hepatectomy (LLH) for hepatolithiasis. From June 2006 to October 2009, 61 consecutive patients with hepatolithiasis who met the inclusion criteria for LLH were treated in our institute. Of the 61 patients with hepatolithiasis, 28 underwent LLH (LLH group) and 33 underwent open left hepatectomy (OLH group). Clinical data including operation time, intraoperative blood loss, postoperative complication rate, postoperative hospital stay time, stone clearance and recurrence rate were retrospectively analyzed and compared between the two groups. LLH was successfully performed in 28 patients. The operation time of LLH group was longer than that of OLH group (158 +/- 43 min vs 132 +/- 39 min, P < 0.05) and the hospital stay time of LLH group was shorter than that of OLH group (6.8 +/- 2.8 d vs 10.2 +/- 3.4 d, P < 0.01). No difference was found in intraoperative blood loss (180 +/- 56 mL vs 184 +/- 50 mL), postoperative complication rate (14.2% vs 15.2%), and stone residual rate (intermediate rate 17.9% vs 12.1% and final rate 0% vs 0%) between the two groups. No perioperative death occurred in either group. Fifty-seven patients (93.4%) were followed up for 2-40 mo (mean 17 mo), including 27 in LLH group and 30 in OLH group. Stone recurrence occurred in 1 patient of each group. LLH for hepatolithiasis is feasible and safe in selected patients with an equal therapeutic effect to that of traditional open hepatectomy.

    ABSTRACT: To investigate the factors influencing the long-term survival of pancreatic carcinoma patients after radical resection. The data of 184 pancreatic carcinoma patients with radical resection were analyzed retrospectively. Analysis of the prognostic factors influencing the long-term survival was performed using Cox proportional hazard regression model. The overall 1-, 3- and 5-year survival rates in this group were 61.7%, 29.0% and 14.3%, respectively. They were 78.0%, 38.4% and 25.7%, respectively, for the patients with a tumor < 3 cm in diameter, significantly better than those with a tumor >or= 3 cm (52.8%, 22.7% and 7.2%, respectively, P < 0.05). Moreover, the 1-, 3- and 5-year survival rates were 67.6%, 30.5% and 17.4%, respectively, in the patients without lymph node involvement, much longer than that in those with lymph node metastasis (37.1%, 20.6% and 0, respectively, P < 0.05). Multivariate analysis by Cox proportional hazard regression model revealed that the tumor size (P < 0.05) and lymph node metastasis (P < 0.01) significantly influenced the long-term survival of the patients. Tumor size and lymph node metastasis are significant factors influencing the long-term survival of pancreatic carcinoma patients with radical resection. Therefore, early diagnosis and radical resection are the key points to improve treatment outcome.
