One hundred one carefully screened morbidity obese patients underwent jejunoileal bypass and were followed closely over a mean follow-up period of 32 months. Although there were no operative deaths, three per cent of patients died postoperatively of liver failure or its complications. A fourth patient died of a pulmonary embolus after reoperation, and the fifth patient died cachectic with severe diarrhea after excessive weight loss. Nineteen per cent of the patients required restoration of intestinal continuity (reversal), most for either liver failure or late fluid and electrolyte derangements. All but two survived reversal and are doing well despite massive weight gain. Fifty-eight per cent of the patients had major complications which either required major reoperation (reversal, cholecystectomy or incisional hernia repair) or were potentially life-threatening (liver failure, hepatic fibrosis or urinary tract stones). As described in other series, abnormalities in serum electrolytes and vitamins were seen. In addition, hypovitaminosis D occurred in a number of patients and as with other serum parameters measured, was time-dependent in that improvement was seen in most patients over the postoperative interval studied. Because of the high rate of complications and reversals, we believe that jejunoileal bypass should be reserved for patients with morbid obesity whose lives are imminently threatened by obesity or its sequellae.

The complication rate in jejunoileal bypass for morbid obesity is unacceptably high. Gastric bypass is technically difficult. In our series, 115 patients have undergone gastric partitioning for morbid obesity. The operation consists of stapling across the stomach below the gastroesophageal junction, leaving a gastric food reservoir of 50--60 cc. A 1 cm opening is left in the central portion of the staple line, allowing slow emptying into the distal stomach. The result is a reduced eating capacity and frequency which produce loss in weight. Three-quarters of the patients are women, and the age range is 17--62 years. Preoperative weights averaged 147 kg. Mean operative time was 48 minutes, and postoperative stay was 6.2 days. All patients were extensively evaluated preoperatively with upper GI series, cholecystogram, a number of blood chemistry tests, and endocrinologic and psychiatric consultations. All patients underwent a preoperative Minnesota Multiphasic Personality Inventory test. Cholecystectomy for cholelithiasis was performed on 18% of the patients at the time of operation. Of the seven patients operated on more than one year ago, five have lost an average of 31.6% of their preoperative weight. Of the 12 operated on less than one year but more than six months ago, eight have lost an average of 21% of their initial weight. The early failure rate of 33% has been reduced to 15% at present. One death occurred from pulmonary embolus 10 days following discharge, giving a mortality rate of .08%. The complication rate is 10%, comprising two pulmonary emboli, two psychoses, one wound dehiscence, one wound hernia, and ten wound infections, six of which were minor. There have been no complications of ulcer disease, reflux esophagitis, liver disease, renal disease, or metabolic disorders. Gastric partitioning is a safe, fast effective alternative for the surgical treatment of morbid obesity.

From November 1970 to August 1974 small intestinal bypass was performed in 475 patients for morbid obesity with an operative mortality of 1.6%. Immediate postoperative complications were superficial wound infection (17 patients), pulmonary complications (seven patients), cardiac complications (five patients), wound dehiscence (nine patients), intestinal tract fistula (four patients), and miscellaneous complications (14 patients). Delayed complications included hypokalemia (28%), hypocalcemia (9%), anemia (11%), calcium oxalate urinary calculi (6%), gout (2%), and hepatic failure (1.4%). Fourteen patients died of late complications. Ventral incisional hernia occurred in 3% of the patients; failure to lose sufficient weight in 21%, all but one occurring in patients with end-to-side shunts. Thirteen end-to-side shunts have been converted to end-to-end shunts because of insufficient weight loss. A team concept is important in the handling of the morbidly obese. Small bowel bypass is effective in producing sustained weight reduction in these patients. Careful and continued study of these patients for the rest of their lives is of paramount importance.

Over an 8-year period, 1246 consecutive patients undergoing abdominal surgery were followed up postoperatively for a maximum of 5 years to study retrospectively the incidence, date of occurrence location and risk factors of incisional hernia. Only 1081 cases were assessable. Overall 94 incisional hernias (9%) were evidenced. The actuarial rate of incisional hernia was shown to be 13% at 5 years, occurring during the first 24 months in 80% of cases. Risk factors were analyzed according to four parameters: patient's status, underlying disease, surgical technique, postoperative complications. Morbid obesity, underlying disease, emergency surgery, wound or deep abscesses or early reoperation were all statistically significant factors. From the overall analysis of results it is shown that at 5 years 13% of patients at risk present postoperative incisional hernia. The two main factors on which surgeons are able to act preventively are the choice of incision site and the onset of wound abscesses. Subcostal incision is the most suitable and prevention of abscesses can be obtained essentially by antibiotic prophylaxis.

During the years 1981-85, 163 patients were treated with gastric banding for morbid obesity. Mean preoperative body weight (+/- s.e.m.) was 121.3 kg +/- 1.4, and mean overweight was 71.5% +/- 1.6 according to Broca's formula. Twenty-four patients had postoperative complications during the first 30 days, mostly minor. Four required reoperation and one of these died. Seventeen patients had late complications, six persistent vomiting necessitating reoperation, eight incisional hernia and three penetration of gastric wall by band. The weight loss was rapid during the first 6 months, and thereafter levelled off. After 2 years the weight loss was 33.4 kg +/- 2.4, corresponding to a mean weight loss of 27.6 percent +/- 1.9 of preoperative weight. There was no significant difference in weight loss expressed as a percentage of preoperative weight between patients operated with an outlet of 12 mm (45 patients) or 15 mm (118 patients), nor between males (37 patients) or females (126 patients). We conclude that our technique of gastric banding seems to be a relatively safe and reliable surgical treatment for morbid obesity. But our follow-up period has been limited to 2 years or less, and a longer follow-up is necessary before the method can be fully evaluated.

A report is presented on gastric bypass (n = 27) and gastroplasty (n = 2) in patients with morbid obesity. One patient died postoperatively (mortality 3.4%). Mean weight prior to operation was 129 kg (96 to 205 kg), i.e. 117% (63 to 253%) in excess of the ideal weight. During a follow-up period of 6 to 46 months, the mean loss of weight amounted to 38 kg (3 to 77 kg). 86% of the patients judged their condition as being very good to good. Diseases related to obesity were reduced to a remarkable degree: hypertension from 43 to 5%, hypertriglyceridaemia from 50 to 5% and diabetes mellitus from 52 to 13%. Two patients had to be reoperated on due to a peptic jejunal ulcer, five because of an incisional hernia. No patient suffered from diarrhoea, calculi of the biliary or urinary tract or electrolyte disorders. On the basis of these results gastric bypass would appear to be indicated for the treatment of obesity not amenable to conventional therapy.

Complications associated with jejunoileal bypass for morbid obesity are being recognized more frequently. A variety of mechanical obstructions in the defunctionalized small-bowel segment have recently been corrected in seven surgical patients. Volvulus of the defunctional limb was the most frequent cause of obstruction. Intussusception, bypass enteritis, fascial hernia, and adhesive bands were also causes of obstruction. Radiographic contrast studies were valuable in establishing the preoperative diagnosis. The altered small-intestinal anatomy predisposed these patients to a uniquely subtle and dangerous form of closed-loop obstruction. Prompt recognition was based on patient history and physical findings. Characteristic roentgenographic findings often confirmed the diagnosis. Clinical suspicision of these small-bowel obstructive syndromes may lead to early surgical treatment.

The SILASTIC ring vertical gastric bypass (SRVGBP) has evolved as the rational operation to control obesity. The operation consists of a proximal vertical gastric pouch < 30 cc in size. The pouch is banded with a 5.5-cm SILASTIC ring, and this functions as the stoma which does not stretch and is large enough to allow patients to eat all varieties of food, including vegetables and meats, with minimal incidence of postprandial emesis. The continuity of the gastrointestinal tract is formed with a Roux-en-Y gastroenterostomy with each limb about 60 cm long. The bypass of the gastroduodenal axis causes decreased digestion and thus decreased absorption of fats and carbohydrates, resulting in comparably more weight loss than seen in the standard restrictive gastroplasty. The dumping experienced in this operation, which prevents patients from becoming sweet eaters and thus provides long-term weight maintenance, is not as severe as in the regular gastric bypass with a dilatable stoma. In trained hands, the morbidity and mortality from this operation is comparable to that seen in the simple restrictive gastroplasty. The complications due to this operation include staple line breakdown, marginal ulcers, stenosis, incisional hernia, dumping, and iron, vitamins A, B12, D, and E deficiencies. These deficiencies are correctable by oral or parenteral supplements as necessary. This operation yields a 90% or higher success rate (> 40% excess weight loss) in the treatment of morbid obesity [corrected].

In this paper the authors consider the problem of incisional hernias as late complications of bariatric surgery. After a description of relationships between obesity and incisional hernias they report their experience on this topic, consisting of 56 patients submitted to bilio-pancreatic diversion between March 1989 and September 1991, for surgical treatment of morbid obesity. Incisional hernias developed in 28% of cases. Analysis of some risk factors like infections, epidemiological patterns, materials and techniques used to suture the abdominal wall, has not allowed identification of significant associations with incisional hernias occurrence. Only early reinterventions (3 cases) have always determined a subsequent development of incisional hernias. The authors confirm the close relationship existing between obesity and incisional hernias. They suggest incisional hernia repair to be undertaken once weight loss has terminated and stabilized, and in the absence of other specific or aspecific morbid obesity surgery complications.

Nowadays, incisional hernias are still one of the more common complications of abdominal surgical procedures. A population, at high risk of developing an incisional hernia, has been chosen for this study, namely patients suffering from morbid obesity. The aim of the study was to compare prospectively the incidence of incisional hernias in 2 groups of patients operated upon for morbid obesity (Vertical Silicone Ring Gastroplasty) with or without intraperitoneal polyglactin mesh. Patients were randomly assigned in the 2 groups. For this preliminary study, 112 patients operated upon before 01/04/1992 were selected; the mean follow-up period was 28.3 months (S.D.:5.7); 81 patients have been reviewed personally, 31 interviewed by phone call or mail. The 2 groups of patients were not significantly different as regarding age, sex, weight, body mass index, diabetes and wound infection. Sixteen incisional hernias were observed in the group with mesh and 17 in the group without mesh. According to these preliminary results, there is no argument for recommending the use of the polyglactin mesh in the prevention of postoperative incisional hernias, in obese patients.
