Bariatric Surgery: Early Results with a Multidisciplinary Team

Background: Bariatric surgery depends on complete preoperative study of morbid obesity, in order to obtain the treatment of choice. A multidisciplinary group was founded in 1998 at the University of Siena. Methods: During 1998, 16 patients, with median weight 121.8 ± 31 kg and median body mass index (BMI) 43 ± 6, underwent bariatric surgery. A multidisciplinary assessment was used in order to evaluate psychological status, food intake problems and patient compliance, and hemodynamic, respiratory, metabolic and arthritic functions. 13 patients were submitted to laparoscopic surgery: in 11 adjustable gastric banding was performed and 2 were submitted to a vertical gastroplasty plus adjustable gastric banding.Three patients were operated via traditional laparotomy, due to previous abdominal surgery in 2 cases (submitted to an adjustable gastric banding) and one woman was submitted to a bilio-intestinal bypass according to the Hallberg technique, for her psychiatric troubles and coexisting systolic hypertension and uncontrolled diabetes. Monthly follow-up for each patient continues after 6 months. Results: No morbidity or mortality has occurred. The median weight loss at three months, was 19.5 kg. Two cases required injection of 1 ml more of fluid into the port, respectively at 4 and 9 months. Fifteen days after surgery, seven patients (46%) had vomiting episodes, due to rapid food intake. All patients have shown an improvement of their comorbidities after surgery. Conclusion: Early results via the multidisciplinary team and laparoscopic banding have been satisfactory thus far.

Giant Sigmoid Diverticulum: A Rare Presentation of a Common Pathology

Although colonic diverticulum is a common disease, affecting about 35% of patients above the age of 60, giant sigmoid diverticulum is an uncommon variant of which only relatively few cases have been described in the literature. We report on our experience with a patient affected by giant sigmoid diverticulum who was treated with diverticulectomy. Resection of the diverticulum is a safe surgical procedure, provided that the colon section close to the lesion presents no sign of flogosis or diverticula; in addition, recurrences are not reported after 6-year follow-up.

Initial Experience with Laparoscopic Adjustable Gastric Banding and Pouch Dilatation: Two Cases

Background: Late proximal pouch dilatation (LPPD) has occurred occasionally following gastric banding for morbid obesity. At present, laparoscopic conservative resetting and oversuturing of the band is considered the standard procedure for pouch dilatation without any important posterior component. Methods: Two cases of LPPD are presented, which occurred in our initial experience with the LapBand®, corrected via a laparoscopic approach. Results: The reintervention was necessary in both patients, with conservative laparoscopic repositioning and oversuturing of the band in the first case and laparoscopic substitution of the gastric band in the second. We have not observed further complications, and weight loss has been maintained in a midterm outcome in both cases (30 and 18 months follow-up). Conclusions: LPPD can be corrected with a conservative laparoscopic surgical approach, without complications and negative functional effects on mid-term outcome.
