We studied the sonographic findings in seven patients in whom afferent loop obstruction was first detected by sonography. All seven subsequently were proved at surgery to have afferent loop syndrome. The causes of the obstruction included internal hernia (n = 3), cancer recurrence (n = 2), marginal ulcer (n = 1), and development of cancer at the anastomosis site (n = 1). In all cases, the dilated afferent loop was seen on sonography as a tubular structure in the upper abdomen crossing transversely over the midline. The distal end of the afferent loop could be traced toward the anastomosis. The probable cause of the syndrome was predicted on the basis of sonography in two of three patients with cancer at the anastomosis. Our experience suggests that afferent loop syndrome can be diagnosed sonographically on the basis of the detection, location, and shape of the dilated afferent loop.

From January 1970 to December 1984, at the "A. De Gasperis" Division of cardiac surgery in 73 patients an open-heart valvular operation and an elective abdominal surgical procedure were simultaneously performed. Abdominal surgery was indicated for: cholelithiasis (41 cases), hernia (22 cases), uterine fibroleiomyomas (7 cases), pregnancy (1 case), marginal ulcer after gastric resection (1 case), association of cholelithiasis and hernia (1 case). The etiology of valvular disease was: previous rheumatic fever (69 cases) and acute bacterial endocarditis (1 case); there were 3 cases of periprosthetic leak. All patients were classified in NYHA class III or IV. In all patients the abdominal procedure was carried out first. No significant differences were noted between this group of patients and patients with isolated open-heart operations regarding: postoperative bleeding, stay in Postoperative Intensive Care Unit, overall postoperative hospital stay. There were 5 hospital deaths, all related to cardiac causes. There were no infectious complications, nor early or late abdominal wound complications. The rationale for the combined approach to abdominal and cardiac diseases includes: risk of non cardiac surgery in patients with critical heart disease, risk of non cardiac surgery in patients with previous cardiac valve operations and anticoagulant therapy and risk of abdominal complications after cardiopulmonary bypass surgery. Simultaneous abdominal and cardiac surgery is suggested on clinical, psychological and social grounds.

The frequency of bariatric surgery has increased markedly in France in recent years, partly due to a better appreciation of the problem of morbid obesity but also due to the commercial introduction of adjustable gastric banding devices which can be placed by laparoscopic approach. Numerous complications of this surgery are known and require recognition to be appropriately treated. Studies of complications suffer from selection bias, methodologic flaws, and lack of follow-up. The incidence and type of complication are affected by the learning curve and surgical techniques. Postoperative mortality varies from 0.14% for laparoscopic gastric banding (LGB), to 0.31% for vertical banded gastroplasty (VBGP) and 0.35% for Roux-en-Y gastric bypass (GBP); pulmonary embolus accounts for 60-70% of deaths in all groups combined. Early post-operative complications vary with specific procedures. Abdominal wall complications, already frequent in an obese population, are decreased from 10% for open procedures to 6% for laparoscopic gastric banding. Both VBGP and GBP are now being done laparoscopically with increasing frequency. Complications specific to LGB include gastric perforation (0.3%), or port problems (5%). Complications with VBGP and GBP include fistula (1-3%), deep abscess, and pulmonary embolus (2%). Global early morbidity is 4.2% for LGB, and varies from 6.4%-22% for VBGP and 6.2%-11.3% for GBP depending on laparoscopic versus open approach. Late mechanical complications are also specific to type of surgery. Pouch dilatation is the most common late complication of LGB (6.3%) and seems related both to operative experience and to site of placement of the band; it has decreased with higher positioning of the band to leave a minimal gastric pouch and with dissection through the pars flaccida of the lesser omentum instead of directly along the muscular wall of the stomach. It usually requires reintervention. Erosion of the gastric band into the stomach (1.6%) is often asymptomatic and is suggested by late weight gain. With VBGP, disruption of a gastric staple line occurs in 12.1% and stenosis of the outlet with proximal dilatation in 6.5%; erosion of the calibrating band of Marlex or silastic occurs in 2.7%. With GBP, the disruption of a staple line across an intact stomach (23%) has become less of a problem with division of the gastric pouch from the distal stomach (2%). Stenosis of the gastrojejunostomy (3.7%) and marginal ulcer (3.5%) are not uncommon. The incidence of wound hernia, obstructive adhesions, and late cholecystectomy vary with the length and thoroughness of follow-up. Late functional complications such as vomiting, dysphagia, heartburn and esophagitis vary with the quality and length of follow-up study. GBP may cause diarrhea and dumping syndrome. Nutritional complications are more common with GPB than with purely restrictive procedures; iron, folate, and Vitamin B12 deficiency are the rule with GBP and require routine replacement therapy; iron deficiency has been noted even with LGB. ate death seems more related to co-morbidities than to the intervention itself. Thorough long-term follow-up study of complications is indispensable for assessment of outcomes and improvement of laparoscopic techniques. Even the less traumatic surgical approach of laparoscopic band placement should not be considered free of risk; strict adherence to pre-operative surgical indications should be maintained.

No standardized approach exists for laparoscopic Roux-en-Y gastric bypass (LRYGB). At a newly instituted bariatric surgery program, four experienced laparoscopic surgeons used the systematic and evidence-based approach consisting of multidisciplinary preoperative evaluation, screening, and education; standardized operative technique; inpatient clinical pathway; and close postoperative follow-up. The outcomes were subsequently analyzed to determine if this approach improved the morbidity and mortality. From January 2003 to June 2006, 835 consecutive LRYGBs were performed. The patient population was 85 per cent women with a mean body mass index (BMI) of 50.4 kg/m2 (range 33-96 kg/m2). The mean age was 44 (range 15-67). Sixty-two per cent of the patients had previous abdominal or pelvic operations. The conversion rate to open surgery was 0.2 per cent. The average length of hospital stay was 2.6 days (range 2-13 days). There were no anastomotic leaks or deaths. The 30-day readmission and re-operation rates were 3.2 per cent and 1.8 per cent, respectively. The incidence of anastomotic stricture, marginal ulcer, bleeding, pulmonary embolism, and internal hernia was 0.8 per cent, 3.5 per cent, 4.2 per cent, 0.1 per cent, and 0.4 per cent, respectively. A systematic and evidence-based approach to the LRYGB by experienced laparoscopic surgeons resulted in a lower incidence of complications when compared with the published results from other comparable institutions.

We aim to review the available literature on morbidly obese patients treated with one anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) in order to compare the clinical outcomes of the two methods. A literature search was performed in PubMed, Cochrane library and Scopus, in accordance with the PRISMA guidelines. Twelve studies met the inclusion criteria (7452 patients). OAGB was associated with shorter mean operative time. The length of hospital stay was comparable between the two procedures. The incidence of leaks, marginal ulcer, dumping, bowel obstruction, revisions and mortality was similar between the two approaches. The incidence of malnutrition was increased in patients treated with OAGB, while the incidence of internal hernia and bowel obstruction was greater in the RYGB group. In addition, the percentage excess weight loss at 1, 2 and 5 years post-operatively was greater for the OAGB group. The rate of type 2 diabetes remission was greater in the OAGB group. The rate of hypertension and dyslipidemia remission was also similar between OAGB and RYGB. Randomized controlled trials, comparing RYGB to OAGB, are necessary to further assess their clinical outcomes.
