    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 evaluate clinical outcomes after laparoscopic total mesorectal excision (TME) combined with intersphincteric resection (ISR) for ultra-low rectal tumors. Clinical data of 36 patients with ultra-low rectal tumor undergoing laparoscopic TME combined with ISR were analyzed retrospectively. The median distance from the inferior margin of the tumor to the anal verge was 3.4 (2.0-5.0) cm. There were 33 cases of well/moderately differentiated adenocarcinoma and 3 rectal malignant villous adenoma. There were 16 patients with stage I disease, 15 with stage II A, 3 with stage III A, and 1 with III B. Postoperatively, one patient developed stenosis at the end ileostomy and 3 anastomotic leakage. After a median follow-up of 16(4-49) months, one patient developed local recurrence at the anastomosis and one case died of liver metastasis. In the 19 patients who had a minimum follow-up of one year, the bowel movements frequency ranged from 1-4 times per day, and these patients were able to withhold defecation for more than 5 minutes. Laparoscopic TME combined with ISR can achieve oncologic clearance, sphincter preservation, and minimal invasiveness for ultra-lower rectal cancer. However, patients selection should be cautious.

    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.
