Transanal specimen extraction in laparoscopic colorectal resection / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility and efficacy of transanal specimen extraction in laparoscopic colorectal resection.</p><p><b>METHODS</b>From January 2009 to December 2010, transanal specimen extraction technique was performed in 12 patients undergoing laparoscopic colorectal resection. The clinical data were retrospectively analyzed.</p><p><b>RESULTS</b>There were 8 males and 4 females. The age ranged from 41 to 67 (mean, 58) years old. The mean operative time was (240±45) min, mean blood loss was (70±40) ml. There was no anastomotic leakage or stenosis. One patient with constipation suffered from intractable right lower abdominal pain and was managed with antispasmodic agents. The frequency of bowel movements was 3-7/d in the 5 patients with constipation and 1-2/d in patients with colorectal carcinoma at six months postoperatively. No local recurrence and metastasis in patients with colorectal cancer after follow-up of 1-20 months.</p><p><b>CONCLUSION</b>Transanal specimen extraction in laparoscopic colorectal resection is feasible, safe, and reliable.</p>

Efficacy evaluation of laparoscopic gastric bypass for the treatment of obese type 2 diabetes mellitus / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To explore the treatment outcomes of obese type 2 diabetes mellitus (T2DM) after laparoscopic gastric bypass.</p><p><b>METHODS</b>The clinical data of 18 patients with obese T2DM who underwent laparoscopic Roux-en-Y gastric bypass in Beijing Shijitan Hospital between March 2009 and February 2011 were retrospectively analyzed. The clinical parameters included preoperative and postoperative blood glucose, blood lipid, nutrition status and weight lose.</p><p><b>RESULTS</b>Eighteen patients included 8 men and 10 women. The range of age was 27-62 years (mean, 42.4±10.7 years). The range of BMI was 28.7-57.4 kg/m(2)(mean, 34.9±6.9 kg/m(2)). All the patients underwent laparoscopic Roux-en-Y gastric bypass, and no mortality, complication or conversion to open operation occurred. At 3 months after operation, there were significant changes in OGTT, BMI, HbA1c, Homa-IR and Homa-β(all P<0.05). Fourteen patients(77.8%) showed clinical complete remission, and the overall effective rate was 100%(18/18). The level of blood lipid decreased significantly (P<0.05), and the change of nutritional status was not statistically significant(P>0.05).</p><p><b>CONCLUSION</b>Gastric bypass is an effective treatment for obese type 2 diabetes mellitus.</p>
