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.

A high incidence of post cesarean section febrile morbidity has caused a number of investigators to recommend using prophylatic antibiotics for patients undergoing this procedure. Recent data suggest that such prophylactic antibiotics should be reserved for high-risk patients. Since previous studies have not adequately defined the high-risk patient, we analyzed 129 patients undergoing cesarean section to identify the factors which predispose to postoperative febrile morbidity. Two different statistical programs identified four factors (general anesthesia, obesity, hematocrit less than or equal to 30%, and labor prior to delivery) which were significantly associated with post cesarean section febrile morbidity (P less than 0.025). Patients with 2 or more of these risk factors were highly likely to experience this postoperative complication (P less than 0.001).

Obese people, more than 45 kg above their ideal weight, can be treated by an intestinal by-pass. This operation must be reserved for patients where conservative treatment failed, where there is no organic origin, and given the operative risk be not increased by underlying serious disease. Good pre- and postoperative collaboration of the patient together with clinical and biological controls are essential. The operation consists of an end-to-side jejuno-ileostomy with proximal suture of the blind loops; or an end-to-end jejuno-ileostomy with implantation of the blind loops in the colon. Loss of weight to near ideal plus improvement of diabetes, hypertension, gout and hyperlipaemia can be expected. Diarhea will occur for a few months or one year. Biochemical values usually remain stable: values for lipids decrease to lower normal if elevated before the operation. During fast weight loss, there are changes in the liver structure and hepatic tests; these are transient and reversible.

Centrally acting appetite suppressant drugs used in the treatment of obesity fall into 2 broad pharmacological categories; those which act via brain catecholamine pathways and those which act via serotonin pathways. Of the former group, amphetamine and phenmetrazine are no longer recommended because of their stimulant properties and addictive potential. The remaining drugs in this class include amfepramone (diethylpropion), phentermine, mazindol and phenylpropanolamine. All have been shown to reduce appetite and lower food intake, thereby helping obese patients more easily keep to a low-calorie diet and lose weight. They all have some sympathomimetic and stimulant properties. Anorectic drugs which promote serotonin neurotransmission have no such stimulant or sympathomimetic properties. They are fenfluramine, together with its recently introduced dextrorotatory stereoisomer dexfenfluramine, and fluoxetine. They reduce appetite and food intake and are effective in the treatment of obesity. Anorectic drugs should be reserved for those who are clinically at risk from being overweight, and then only as part of a comprehensive weight-reducing programme including regular dietary counselling. Although current licensing regulations only allow their use over a relatively short period (12 to 16 weeks), clinical trials have shown them to be effective over longer periods, particularly in preventing weight regain. Of the compounds currently indicated for use in obesity, dexfenfluramine appears to have the most suitable pharmacological profile, although it should not be given to patients with a history of depression. When used appropriately, appetite suppressants can be of real therapeutic benefit, and pose little risk.

One hundred patients underwent coronary revascularisation with both internal mammary arteries between 1987 and 1990. The average age of the patients was 55 years. The left internal mammary was used in 97 of the 100 cases as a pediculated graft to revascularise the left anterior descending (66 cases), left lateral (27 cases) or a bissecting artery (4 cases). The right internal mammary was used as a pediculated graft in 51 cases and as a free graft to revascularise a left lateral (51 cases), left anterior descending (29 cases) or right coronary artery (20 cases). There was one death in the first 30 postoperative days. Morbidity was low with no cases of sternal infection. The average postoperative bleeding was 633 +/- 550 ml per patient. The incidence of phrenic nerve paralysis decreased from 36% in the first 50 patients to 6% in the second 50 patients. Angiography at the 10th postoperative day showed 4 occlusions out of 132 internal mammary arteries opacified (97% patency). Ninety four patients are asymptomatic and have negative exercise stress tests. Mortality and morbidity of coronary surgery using the two internal mammary arteries are therefore the same as those of conventional coronary surgery using saphenous veinar only one internal mammary artery, providing that it is reserved for patients in good general condition, under 65 years of age, without obesity or diabetes. This technique of coronary artery revascularization should provide better long-term results because of the high patency rate of the grafts.

Nonsurgical methods fail to maintain clinically significant weight loss greater than or equal to 5 y in severely obese patients. Vertical banded gastroplasty and Roux-Y gastric bypass are the main operations for obesity. Modifications of intestinal bypass reserved for special cases require particular expertise in long-term management. Operations function by inducing satiety, nimiety, or aversion. Optimal weight loss or goal weights have not been defined and outcome predictors are inadequate. Results depend more on motivation and behavior than on metabolic, gastrointestinal, or technical factors. New approaches such as adding vagotomy or using inflatable cuffs to adjust outlet size in gastroplasty or modifying outlets or segment lengths in gastric bypass might improve long-term results. A staged approach to surgical treatment of obesity is proposed. Surgery will persist as a viable treatment alternative for severe obesity until effective preventive measures are taken to reduce the prevalence of this serious disease.

Based on accumulating evidence, an important shift in the nonsurgical treatment paradigm for low back pain is underway. This shift is away from prolonged rest and passive therapy toward earlier patient activation and greater use of exercise therapy. The patient's best interest is often served by encouraging an early return to work and by avoiding adversarial legal proceedings. Patients should be reassured about the good prognosis of acute pain, and the alarming terminology of "injury" or "ruptured disc" should be avoided. Intervention to avoid sedentariness, smoking, and obesity probably offers important therapeutic and preventive opportunities. When surgery is indicated, the patient should have a major role in decision making after being provided an accurate view of risks and benefits of surgical intervention. Surgery should generally be reserved for those cases for which a benefit of surgery has been clearly established, avoiding the liberalization of indications to include imaging findings alone, persistent pain alone, or the failure of other treatments in the absence of clear surgical indications.

Of 22 patients investigated for sleep disorders, habitual snoring and/or daytime hypersomnolence, 12(10 men) had obstructive sleep apnea syndrome (OSAS). 3 OSAS were mild, 5 moderate and 4 severe. The leading symptoms were daytime hypersomnolence and habitual snoring. As risk factors we found retro-micrognathia in 2 patients, macroglossia secondary to acromegaly in 1, alcohol abuse in 7 and obesity in 6. Conservative measures improved the disorder subjectively in 6 patients. One patient had a relapse 6 months after uvulopalatopharyngoplasty. 4 patients were successfully treated by nasal CPAP. Other diagnoses were idiopathic alveolar hypoventilation (2), Cheyne-Stokes breathing secondary to low cardiac output (1), monosymptomatic narcolepsy (2), sleep disturbances secondary to depression (2), chronic benzodiazepine abuse (1) and chronic bronchitis without nocturnal hypoxemia (1). History, clinical observation and oxymetry make diagnosis possible in most cases of OSAS severe enough to require treatment. Polysomnography is time-consuming and should be reserved for selected cases.

Conventional diets and increased exercise are the cornerstones of traditional therapy for obesity, but available data suggest that the most important component of any program is the associated behavior modification through which new ways of dealing with old problems can be learned and continually applied. This combined with very-low-calorie diets--less than 800 kcal per day--are in wide use, mostly under medical supervision. The currently available appetite-suppressing drugs are of limited efficacy, but many new ones are under active development and hold promise for the future. The most effective surgical intervention appears to be the gastric bypass operation, but this should be reserved for those who are at high risk from their obesity.

An electronic bone growth stimulator (EBGS) had been devised to facilitate lumbosacral fusion in the early 1970s, using a totally implanted device which delivers a steady 5 microA at each of four cathodes. The use of the device is reserved for patients in whom painful and abnormal motion is demonstrated to be the major cause of low-back pain. An initial series (I-A) of 82 patients demonstrated a successful fusion rate of 91.5% compared with a 80.5% fusion rate in 159 patients treated without the EBGS. A second prospective randomized controlled trial series (II) was begun using only "difficult patients," that is, patients who had either one or more previous failed fusions, a grade II or worse spondylolisthesis, a multiple-level fusion or the presence of another high-risk factor such as obesity. These patients were randomized by protocol as to whether they received a stimulator or not. The fusion rates of the two groups were assessed radiographically by the operating surgeon and by an independent radiologist 12 to 18 months postoperatively. Statistical review confirmed the comparability of the groups. Success, defined as radiographic fusion, was achieved in 15 of 28 control patients (54%) compared with 25 of 31 EBGS treated patients (81%). This result is statistically significant (P = 0.026, one-tailed Fisher's Exact test). Meanwhile, a continuing nonrandomized study (I-B) has continued and at this point the success rate is 90.5% in an additional 116 patients, confirming the results of the earlier nonrandomized series (I-A).(ABSTRACT TRUNCATED AT 250 WORDS)
