The authors studied serial hepatic biopsies of five patients who developed hepatic failure following jejunoileal bypass for extreme obesity, with autopsies of two. The hepatic histologic changes included centrilobular or focal alcoholic hyalin, intrasinusoidal collagenosis, fatty hydropic degeneration, and neutrophilic infiltrate. At least two of the patients were abstinent from alcohol, both prior to and after the surgical procedures. The others, after the bypass procedures, had reduced alcohol consumption from previous levels. All patients developed hepatic failure and histologically progressive hepatic disease with alcoholic hyalin and other changes indistinguishable from alcoholic hepatic disease in 21/2 to 5 months, in spite of hyperalimentation and re-establishment of intestinal continuity in four. Nausea, vomiting, abdominal pain and ascites were prominent complaints. Four of the five patients died in hepatic failure. The authors conclude that these cases of progressive hepatic disease with histologic changes simulating those found in livers of alcoholic patients offer evidence that heavy alcohol consumption may affect the liver in an indirect fashion.

Abdominal wound dehiscence is a surgical complication with a high morbidity rate but which is associated with predictable and preventable factors. During a 10 year period (1966 to 1975) at the New York Lying-In Hospital, 70 cases were found on the obstetric-gynecologic service, and these cases were analyzed to see why dehiscence remains a problem. Those factors contributing to dehiscence include obesity, pre-existing pulmonary and cardiovascular problems, vertical incisions, the triad of ileus, vomiting, and coughing, and, to a lesser extent, hypoproteinemia, fluid and electrolyte imbalance, and wound infection. The incidence of abdominal wound dehiscence would be much lower if high-risk patients were identified, adequate pulmonary toilet was used, ileus was promptly treated with abdominal decompression, and strict attention was paid to electrolyte and protein balance in the pre- and post-operative period. The management of abdominal wound dehiscence is also discussed.

Total starvation is effective for acute weight reduction in obesity. However, in 200 patients, most of whom also had internal diseases, 8% exhibited sometimes severe complications, i.e. reversible cerebral ischemia in 3 hypertensive patients when the blood pressure was lowered to the normal range by natriuresis of fasting; breakdown of water and electrolyte homeostasis with circulatory collapse, vomiting and vertigo; acute crises of paroxysmal nocturnal hemoglobinuria and porphyria respectively and increase of transaminases up to 200 mu/ml, or cardiac arrhythmias. Relative (?) contraindications for total fasting appear to be clinical sings of arteriosclerosis such as vascular bruits, angina pectoris and intermittent claudication. In case of doubt, the method should only be used in hospital.

This review will first describe problems in the definition of the term binge eating, especially in the absence of purging (vomiting, laxative abuse). We highlight current approaches in the classification of obesity, and then provide an overview of the available literature on differences between obese binge eaters and obese non-binge eaters. Many studies indicate that binge eating is common among the female obese, with a frequency ranging from 23 to 46% among those seeking treatment for weight reduction. Despite differences in the definitions of binge eating and variability among the samples investigated, there is strong evidence that binge eaters represent a distinct subgroup among the obese. Binge eating obese exhibit significantly more eating and weight-related pathology, as well as more psychopathology compared to their non-binge eating obese counterparts.

While the number of patients at risk for vomiting and aspiration has been reported to be high, the incidence of clinically important pulmonary aspiration is low. We sought to define the incidence of gastroesophageal reflux (GER) and to correlate this with the clinical variables of obesity, history of oesophagitis, bucking and changes in body position. Continuous oesophageal pH measurement was used to determine the frequency of gastroesophageal reflux in 44 patients having general anaesthesia for elective surgical procedures. Acid reflux to a pH value of less than four occurred in seven patients (15.9%) during anaesthesia. This was associated temporally with straining on the endotracheal tube in six subjects (13.6%). We conclude that traditional risk factors are not always predictive of those patients at risk of regurgitation and aspiration.

In a recent editorial, Kapur described perioperative nausea and vomiting as "the big 'little problem' following ambulatory surgery."257 Although the actual morbidity associated with nausea is relatively low in health outpatients, it should not be considered an unavoidable part of the perioperative experience. The availability of an emesis basin for every patient in the postanesthesia recovery unit is a reflection of the limited success with the available therapeutic techniques.257 There had been little change in the incidence of postoperative emesis since the introduction of halothane into clinical practice in 1956. However, newer anesthetic drugs (e.g. propofol) appear to have contributed to a recent decline in the incidence of emesis. Factors associated with an increased risk of postoperative emesis include age, gender (menses), obesity, previous history of motion sickness or postoperative vomiting, anxiety, gastroparesis, and type and duration of the surgical procedure (e.g., laparoscopy, strabismus, middle ear procedures). Anesthesiologists have little, if any, control over these surgical factors. However, they do have control over many other factors that influence postoperative emesis (e.g., preanesthetic medication, anesthetic drugs and techniques, and postoperative pain management). Although routine antiemetic prophylaxis is clearly unjustified, patients at high risk for postoperative emesis should receive special considerations with respect to the prophylactic use of antiemetic drugs. Minimally effective doses of antiemetic drugs can be administered to reduce the incidence of sedation and other deleterious side effects. Potent nonopioid analgesics (e.g., ketorolac) can be used to control pain while avoiding some of the opioid-related side effects. Gentle handling in the immediate postoperative period is also essential. If emesis does occur, aggressive intravenous hydration and pain management are important components of the therapeutic regimen, along with antiemetic drugs. If one antiemetic does not appear to be effective, another drug with a different site of action should be considered. With the availability of new antiserotonin drugs, the incidence of recurrent (intractable) emesis could be further decreased. Research into the mechanisms of this common postoperative complication may help in improving the management of emetic sequelae in the future. As suggested in a recent editorial, improvement in antiemetic therapy could have a major impact for surgical patients, particularly after ambulatory surgery. Patients as well as those involved in their postoperative care look forward to a time when the routine offering of an emesis basin after surgery becomes a historical practice.

Data on the prevalence and characteristics of binge eating in a series of 64 obese women participating in a controlled weight-reduction program are presented. Twenty-two (34.4%) reported recurrent binge eating episodes defined as overeating plus loss of control as assessed by patients' self-report and confirmed by a clinical interview. Six of those indicated that they engaged in either self-induced vomiting or laxative use to control their weight, but only two met full criteria for current bulimia nervosa according to DSM-III-R. A detailed description of the binge eating behavior revealed similarities to the eating pattern described in patients with bulimia nervosa: obese binge eaters tended to overeat in the evening, when they were alone and at home. Compared with their non-binge eating counterparts, binge eaters were significantly younger when they presented for treatment. The prevalence of childhood obesity was higher, and they were significantly younger when they first started on a diet than the non-binge eaters. Binge eaters reported more psychological problems such as body image distortion, and there was a slight tendency for binge eaters to exhibit more depressive symptomatology at baseline. No association between binge eating and weight at baseline, or weight loss during therapy or at follow-up could be found. Fluvoxamine (100 mg) did not seem to be of specific benefit in this subgroup of the obese with regard to weight loss.

Forty-three young female patients admitted consecutively to hospital with anorexia nervosa (AN) were re-evaluated in late adolescence an average of 4.3 years following initial presentation. Follow-up interviews were conducted individually by a paediatrician and a psychiatrist on 32 of the original 43 patients (mean age 18.3 years) with outcome assessed by multidimensional physical, menstrual, eating behaviour, psychosocial and global outcome criteria. Physical outcome, as assessed by validated indices of body adiposity, was within the normal range (3-97th percentiles) in 94% of the 32 patients seen at follow-up, although only 56% reported regular cyclical menstrual function. Good physical outcome, however, was not necessarily predictive of successful adjustment in other areas. Eating behaviour was unequivocally normal in only 25% of patients, with a majority still dieting, binging or vomiting with meals, Psychosocial adjustment was satisfactory in the majority of cases but varied widely. Univariate and multivariate statistical analysis identified higher premorbid and admission body mass index (BMI) percentiles, a family history of obesity and shorter duration of illness on admission as significant prognostic indicators of favourable physical outcome. Although girls who develop AN in early adolescence are generally thought to have a favourable long-term prognosis, health professionals need to be aware that these patients form a heterogeneous group and may have considerable ongoing physiologic and psychologic disturbance despite normalization of body mass.

Reports of major dissatisfaction among adolescent girls over body shape and their associated eating behaviour, prompted determining anthropometric and questionnaire studies on series of rural and urban black, Indian, and white girls aged 14-19 years. Variables were concern over weight, desired weight loss, also practices regarding binge eating, fasting, vomiting and laxative use. Black girls have low weight-for-age, yet experience more obesity than white girls; yet weight reduction, although desired, is seldom seriously attempted. Indian girls have low weight-for-age, principally for genetic, not social class, reasons; they also, even some underweight, desired weight reduction. White girls are also dissatisfied, although less acutely than girls in the US. The current attitudes of South African adolescent girls, apart from extremes, are unlikely to seriously prejudice their health.

A 35-year-old woman became pregnant 15 months after gastric banding, during which time she lost 55 kg in weight. During the third trimester, severe vomiting was noted and she lost a further 6 kg. Ultrasound examination showed oligohydramnions and fetal growth retardation of 38%. Enteral nutrition was given until delivery and ultrasound verified normalization of the oligohydramnions and weight gain for the fetus. The woman was delivered by cesarean section of a female infant with birthweight 2,470 g. It is concluded that special care must be taken with regard to the nutritional status of pregnant women who have previously been operated on with gastric procedures for obesity, in order to diminish the risk of fetal growth retardation. Ultrasound examinations should be performed on wide indications and enteral nutrition must start immediately once fetal growth retardation is discovered.
