ABSTRACT: Internal hernia is a relatively common complication of laparoscopic Roux-en-Y gastric bypass. Laparoscopic treatment may be a challenge for nonbariatric surgeons if small-bowel obstruction is present. The aim of this paper is to present a systematic laparoscopic technique for hernia reduction and mesenteric defect closure in patients with small-bowel obstruction due to an internal hernia as a postoperative complication of laparoscopic Roux-en-Y gastric bypass. From February 2007 to May 2011, this technique was used in 41 consecutive patients. One case was converted to an open approach due to extensive bowel necrosis. There were no complications related to the technique but 2 patients suffered pulmonary aspiration during anesthesia. After the internal hernia repair patients reported no further abdominal symptoms. Treatment of small-bowel obstruction due to an internal hernia should be attempted by laparoscopy except in the setting of bowel necrosis. The technique presented in this article represents a safe and effective option for the management of this complication.

ABSTRACT: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most widely used bariatric procedures today, and laparoscopic sleeve gastrectomy (LSG) as a single-stage procedure for the treatment of morbid obesity is becoming increasingly popular. In this study, we prospectively compared both techniques in order to establish whether there is any superiority of one over the other based on morbidity and effectiveness. From January 2008 to December 2008, 117 obese patients with indication for bariatric surgery were assigned by patient choice after informed consent to either a LRYGB procedure (n = 75) or a LSG procedure (n = 42). We determined operative time, length of stay, morbidity, co-morbidity outcomes, and excess weight loss at 1 year postoperative. Both groups were comparable in age, sex, body mass index, and co-morbidities. Mean operative time of LSG was 82 min while LRYGB was 98 min (p < 0.05). Differences in length of stay, major complications, improvement in co-morbidities, and excess weight loss were not significant (p > 0.05). One year after surgery, average excess weight loss was 86% in LRYGB and 78.8% in LSG (p > 0.05). In the short term, both techniques are comparable regarding safety and effectiveness, so not one procedure is clearly superior to the other.

ABSTRACT: Medical treatment of type 2 diabetes has often insufficient clinical results at long term. Although the surgical option is a well-established alternative for obese patients, the procedures in non-obese are currently being developed.
A 12-month prospective trial with ten diabetic non-obese patients who underwent laparoscopic sleeve gastrectomy with duodenojejunal bypass is presented. Changes in fasting blood glucose, HbA1c, weight, and BMI were determined.
There was a significant reduction in fasting glycemia and HbA1c at 1 year postoperative (p < 0.004). One patient had an intra-abdominal bleeding and a wound infection treated with blood transfusion and antibiotic therapy, respectively. The BMI decreased 12.1% and in any case it was reduced to less than 20 kg/m².
Laparoscopic sleeve gastrectomy with duodenojejunal bypass is a promising procedure for the treatment of non-obese patients with type 2 diabetes. Studies with large number of patients and longer follow-up are necessary to make definitive conclusions.

ABSTRACT: We present a randomized controlled trial of laparoscopic gastric bypass comparing 2 techniques of gastrojejunostomy in patients with morbid obesity.
Eighty consecutive patients underwent laparoscopic Roux-en-Y gastric bypass between September 2005 and August 2006. Patients were randomly assigned to 2 groups by the use of sealed envelopes. In group A, the gastrojejunal anastomosis was performed with a 21-mm circular-stapler, and in group B, this anastomosis was performed with a 45-mm linear-stapler. The rest of the procedure was identical in both groups. Variables evaluated were complications involving the gastrojejunostomy, operative time, length of stay, and percentage of excess weight loss.
Both groups were similar in age and body mass index. No patients experienced leakage or gastrojejunal anastomosis fistula, but group A patients had a more frequent stricture rate (P<0.05). Operative time and hospital stay were comparable in both groups (P>0.05). Percentage excess weight loss at one year following surgery was satisfactory in both groups, without a statistically significant difference (P>0.05).
Gastrojejunal anastomosis does not seem to be a critical factor in excess weight loss for morbidly obese patients who underwent laparoscopic gastric bypass. The 2 techniques used in this experience are safe and effective; however, the 45-mm liner-stapler is preferable because it has a lower stricture rate.

ABSTRACT: Urachal disease is uncommon. The surgical treatment consists of the resection of the urachus throughout its entire length. Our objective is to demonstrate the use of minimally invasive surgery to treat this disease.
Six patients were studied and diagnosed. The technique used three 10-mm ports on the right hemi abdomen, through which the dissection of the urachus was performed from the umbilical extreme to the bladder. We evaluated the perioperative records to assess morbidity and outcome.
Most patients suffered from episodes of umbilical discharge. The diagnosis was made mainly through clinical history and confirmed during the laparoscopic procedure. The urachus was resected throughout its entire length, and we did not perform a segmentary bladder resection in any patient. The average operative time was 66 minutes (range, 42 to 123), and no operative complications were associated with the technique.
Minimally invasive surgery is a safe and effective procedure that allows the dissection of the urachus through its entire length, providing optimal postoperative results.
