ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the outcomes after laparoscopic gastrointestinal surgery for patients with obesity and type 2 diabetes mellitus(T2DM).</p><p><b>METHODS</b>From June 2003 to June 2010, 219 patients underwent laparoscopic gastrointestinal surgery for obesity and T2DM, including laparoscopic adjustable gastric banding(LAGB, n=201), laparoscopic mini gastric bypass(LMGB, n=13), and laparoscopic sleeve gastrectomy(LSG, n=5). Clinical data were analyzed retrospectively.</p><p><b>RESULTS</b>The mean body mass index(BMI) of patients who received LAGB was 37.9 kg/m(2), and decreased to 32.4 kg/m(2) at 6 months and to 29.7 kg/m(2) at 12 months. In 43 patients who had concurrent T2DM, 11(25.6%) showed clinical partial remission(CPR) and 16(37.2%) clinical complete remission (CCR). Postoperative complications occurred in 26 patients(12.9%). The mean BMI of patients undergoing LMGB was 34.7 kg/m(2), and decreased to 31.6 kg/m(2) at 6 months and 26.9 kg/m(2) at 12 months after surgery. Ten patients had T2DM before operation, of whom 2(20.0%) had CPR and 7(70.0%) CCR postoperatively. Postoperative complications occurred in 2 patients(15.4%). The mean BMI of patients who underwent LSG was 43.8 kg/m(2), and was reduced to 38.1 kg/m(2) at 6 months and 34.3 kg/m(2) at 12 months after operation. Three patients were diagnosed with T2DM before operation. One patient (33.3%) had CPR and 1(33.3%) reached CCR after operation. There was 1(20.0%) patient who developed complication. No perioperative death occurred.</p><p><b>CONCLUSION</b>Laparoscopic gastrointestinal surgery may result in satisfactory weight loss and clinical remission of T2DM with few complications.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To report the newly developed reconstruction technique after laparoscopic total gastrectomy: intracorporeal circular stapling esophagojejunostomy using the transorally inserted anvil (OrVil; Covidien), and evaluate its feasibility, safety, and clinical outcomes.</p><p><b>METHODS</b>After LTG (3 patients with gastric carcinoma in the body) or LPG (2 patients with gastric carcinoma in the cardiac and fundus, respectively, and 1 with cardiac stromal tumor), the anvil was then inserted transorally into the esophagus by using the OrVil system. Double-stapling esophagojejunostomy or esophagogastrostomy with a circular stapler was performed intracorporeally.</p><p><b>RESULTS</b>The operations were uneventful. The operative time was (183.3+/-25.8) min, and blood loss was (128.3+/-90.2) ml. Postoperative fluorography revealed no anastomotic leakage or stenosis. Patients resumed an oral liquid diet on postoperative day (4.0+/-1.1), and were discharged on day (9.0+/-2.6). Patients were followed at 28 days and no complications were reported.</p><p><b>CONCLUSIONS</b>LTG with Roux-en-Y reconstruction or LPG with esophagogastrostomy using the OrVil system appear to be safe and reliable with satisfactory short-term outcomes.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of Gastric bypass surgery on the apoptosis of islet β-cells in type 2 nonobese diabetic (NOD) rats and its mechanisms.</p><p><b>METHODS</b>Seventy-two 8-week-old GK rats were randomly divided into four groups:operation group (group O, n = 18), sham operation group (group S, n = 18), diet control group (group F, n = 18) and control group (group C, n = 18). The levels of fasting, postprandial blood glucose, insulin and glucagon-like peptide-1 (GLP-1) were measured and compared among the 4 groups before the operation and at 1, 2, 4 and 8 weeks following the operation. The blood samples were collected at 2, 4 and 8 weeks after the operation for the measurement of postprandial blood glucose, and then the rats in batches (6 rats in each group) were decapitated to retrieve the pancreas. The apoptosis of the islet β-cells was detected by using TUNEL assay, and the expression of apoptosis-related proteins Bcl-2, Bax was measured with immunohistochemistry.</p><p><b>RESULTS</b>As for group O, the fasting blood glucose level decreased from (16.2 ± 0.8) mmol/L before the operation to respectively (9.2 ± 0.6) mmol/L and (9.7 ± 0.7) mmol/L at 4 and 8 weeks after the operation; postprandial blood glucose decreased from (31.1 ± 1.1) mmol/L before the operation to respectively (13.1 ± 0.7) mmol/L and (12.3 ± 0.7) mmol/L at 4 and 8 weeks after the operation. Fasting insulin level increased from (28.0 ± 1.2) mU/L before the operation to respectively (62.8 ± 1.9) mU/L and (61.7 ± 1.4) mU/L at 4 and 8 weeks after the operation; and at 4 and 8 weeks after the operation postprandial insulin level was (77.4 ± 1.1) mU/L and (77.1 ± 1.0) mU/L. At 2 weeks from the operation, the fasting GLP-1 in group O increased from (10.7 ± 1.0) pmol/L to (13.5 ± 0.8) pmol/L, and respectively to (26.1 ± 0.9) pmol/L and (25.3 ± 1.2) pmol/L at 4 and 8 weeks after the operation. The differences in the above-mentioned items before and after the operation were all significant in group O (P < 0.05), and the differences in the items among group O and the other three groups (P < 0.05) were all significant as well. In group O, the apoptosis rate of pancreatic islet cell decreased to (5.9 ± 0.7)% at 4 weeks from the operation, and (6.3 ± 1.1)% at 8 weeks from the operation (P < 0.05). The expression of Bcl-2 protein in group O was 31.3 ± 1.5, 35.7 ± 1.0 and 35.8 ± 0.8 at 2, 4 and 8 weeks post operation, which was significantly higher in statistics than those of the same time point in the other three groups (P < 0.05). The expression of Bax protein in group O was 13.3 ± 0.9, 10.8 ± 0.9 and 10.9 ± 1.1 at 2, 4 and 8 weeks from the operation, which was significantly lower in statistics than those of the same time point in the other three groups (P < 0.05).</p><p><b>CONCLUSIONS</b>Gastric bypass surgery can significantly reduce the blood glucose level and promote the secretion of GLP-1, and therefore inhibit the apoptosis of the islet β cells in diabetic rats through the Bcl-2 pathway.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the benefit of neoadjuvant chemotherapy in advanced gastric cancer patients treated by laparoscopy.</p><p><b>METHODS</b>Fifteen patients with histologically proved gastric adenocarcinomas (stages II(, III(, IIII(M(0)) were treated with FOLFOX7 neoadjuvant chemotherapy followed by laparoscopy between June 2005 and March 2007( trial group). Thirty patients were assigned to the control group with only laparoscopic treatment in the same period. The clinicopathological data were compared between two groups.</p><p><b>RESULTS</b>All the patients in trial group accepted four cycles of preoperative chemotherapy and the toxicity was less than grade 3. Two of them achieved complete response, 10 achieved partial response and 3 kept stable disease. Ten patients of trial group underwent laparoscopic-assisted radical gastrectomy. The rates of R(0)-resection(80.0%) and pN(0) (60.0%) in trial group were significantly higher than those in control group(46.7% and 20.0%), while the rate of positive lymph node 11.0%(34/309) was significantly lower than that of control group 23.8%(142/596). The operation time and postoperative complication were similar in two groups.</p><p><b>CONCLUSIONS</b>Advanced gastric cancer after neoadjuvant chemotherapy can be down-regulated in the stage, increase the rate of R(0)-resection, diminish the infiltration extent of tumor, decrease the metastasis of lymph node, and increase the possibility of laparoscopic radical gastrectomy.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the outcome of weight loss by laparoscopic adjustable gastric banding (LAGB) on obesity patients and the improvement of comorbidity.</p><p><b>METHODS</b>From June 2003 to June 2009, the data 172 obesity patients(119 women, 53 men, mean age 28.5 years, mean body mass index 38.5 kg/m(2)) were analyzed. Comorbidities included 28 cases with diabetes, 36 with hypertension, 85 with dyslipidemia, 56 with sleep apnea and 138 with fatty liver.</p><p><b>RESULTS</b>Mean body mass index(BMI) at 1,3,6,12, 24, 36 and 48 months was 37.2 kg/m(2),35.9 kg/m(2), 34.5 kg/m(2), 32.9 kg/m(2), 30.7 kg/m(2), 29.2 kg/m(2) and 28.1 kg/m(2), respectively. The percentage of excess weight loss(% EWL) at 1, 3, 6, 12, 24, 36, and 48 months was 10.1%, 16.2%, 25.1%, 37.4%, 51.3%, 59.0% and 62.1%, respectively. At 24, 36 and 48 months, respectively, 50.7%, 63.6% and 70.0% of patients had more than 50% excess weight loss. Complications included 6 cases of port infection, 3 of other port problem, 7 of gastric pouch dilatations, 4 of slippage and 1 of chronic intestinal obstruction. Bands of 5 patients were explanted. No death occurred. Blood glucose of 60.7% patients with diabetes was controlled well without any drug. The blood pressure of 22 hypertensive patients became normal. The blood fat of 49 hyperlipidemia cases returned to normal. The symptom of 29 patients with sleep apnea disappeared. All the patients with fatty liver were improved in different degree.</p><p><b>CONCLUSION</b>Gastric banding provides good weight loss and significant reduction in comorbidities with few and minor complications.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the immunity of morbid obesity (MO) before and after laparoscopic adjustable gastric banding (LAGB).</p><p><b>METHODS</b>15 cases, with a mean body mass index (BMI) of 35.8 kg/m(2), were treated by LAGB from Jun. 2003 to Oct. 2003 in our department. Patients' immune parameters were determined preoperatively and 1, 3 and 6 months postoperatively. 15 cases with a normal BMI (23.6 kg/m(2)) were set as controls.</p><p><b>RESULTS</b>Before surgery, the MO had a significant lower level of CD(4)(+), CD(4)(+)/CD(8)(+) and a higher level of serum interleukin-2 (IL-2), Interleukin-6 (IL-6) than the controls (P < 0.01). There was a significant reduction of weight and BMI 6 months postoperatively (P < 0.01). At the same time, CD(4)(+) increased and serum IL-2 decreased significantly. But CD(4)(+)/CD(8)(+)and serum IL-2, IL-6 were still abnormal compare to the controls.</p><p><b>CONCLUSIONS</b>MO may combined with an abnormal immunity. But after enough weight loss induced by LAGB, it can be partly reversed.</p>
