The most serious adverse effect of standard intestinal bypass for obesity is the high incidence of hepatic dysfunction and death from hepatic failure. We therefore examined the long-term effects of a modified form of jejunoileal bypass (in which a greater continuous length of ileum is retained), on liver function in 120 patients. Substantial weight loss (119-0+/-SD 23-3 kg to 82-3+/-18-8 kg) occurred during the first nine months after surgery, accompanied by a significant rise in serum concentrations of bilirubin, alanine transferase, and alkaline phosphatase, and a significant reduction in albumin concentrations. Biochemical changes were unrelated to weight loss or halothane anaesthesia. After weight stabilisation liver function reverted to normal, and four years after bypass sulphobromophthalein retention and hepatic histology did not differ from those in obese controls. There were two postoperative deaths. Three other patients died during the period of rapid weight loss with severe hepatic steatosis. While transient mild impairment of liver function is common after modified jejunoileal bypass, clinically significant hepatic dysfunction is a rare and unexplained early complication.

Anesthetic biotransformation and renal function were studied in obese adult patients (148 plus or minus 8 kg; mean plus or minus SE) anesthetized for three hours with 60 per cent nitrous oxide plus either methoxyflurane or halothane for elective jejunoileal small-bowel-bypass operations. There was no evidence of persistent renal dysfunction in any patient postoperatively, but serum osmolality was elevated 72 hours after methoxyflurane anesthesia. Urine concentrating ability was not determined. Peak serum ionic fluoride concentration was 55.8 plus or minus 5.8 muM/1 two hours after discontinuation of methoxyflurane. Urinary ionic fluoride and oxalate excretions increased postoperatively. Compared with previously reported data from nonobese patients, serum ionic fluoride concentrations in obese patients increased more rapidly during methoxyflurane anesthesia and peaked higher and sooner after discontinuation of methoxyflurane. The peak serum ionic fluoride concentration was 10.4 plus or minus 1.5 muM/1 at the conclusion of halothane anesthesia, significantly more than the corresponding value in nonobese patients. Intraoperative liver biopsies from 23 of 27 patients showed moderate to severe fatty metamorphosis. Fatty liver infiltration may have increased hepatic anesthetic uptake and exposed more methoxyflurane or halothane to hepatic microsomal enzymes. The more rapid elevation and higher peak levels of serum ionic fluoride following methoxyflurane, and to a lesser extent following halothane, may reflect increased anesthetic biotransformation in obese compared with nonobese patients. To avoid excessive serum ionic fluoride elevations the authors recommended limiting low-dose methoxyflurane anesthesia delivered to obese patients with potential fatty liver infiltration to no more than three hours.

A 23-yr-old woman presented in labour and hepatic failure. The clinical diagnosis was acute fatty liver of pregnancy. A Caesarean section was performed under epidural anaesthesia, after correction of a coagulopathy. Epidural anaesthesia was chosen because of the potential deleterious effects of general anaesthesia on liver blood flow and function.

Obstetrical deaths at the Mount Hope Women's Hospital, Trinidad, were reexamined from records over 1981-1990, and discussed under the categories poor prenatal care, clinical management or provision of medical facilities. There were 19 obstetrical deaths out of 57,012 live births, giving a maternal mortality rate of 33.3/100,000 in this tertiary care hospital. Most of the deaths occurred in women aged 30-34, para 5 or more. 73.7% were related to hypertension in pregnancy, 8 with severe eclampsia and 6 with eclampsia, and the other 5 were due to placental abruption, postpartum hemorrhage, anesthesia complication, acute fatty liver and amniotic fluid embolism. Cases classified as substandard care included the 14 women with hypertensive disorders, none of whom had antenatal care at this specialized unit. In 3 referral by the practitioner was delayed, and 3 others did not comply. A woman listed under failed medical facilities had massive abruptio placenta, and no fresh blood was available, and another had an anaphylactic reaction to a mismatched blood transfusion. Other avoidable deaths were 3 associated with general anesthesia: one woman having emergency cesarean section for severe pre-eclampsia had anoxia and severe brain damage; another short, obese woman had cardiac arrest during a failed attempt at endotracheal intubation; a third died from aspiration of gastric fluid. The high mortality among women with hypertensive disorders is regrettable, considering lack of referral to this specialized unit, but the prognosis of eclamptics even with expert aggressive treatment is poor. This maternal mortality rate ranks midway between those of developed countries and developing countries. It is about four times that of the U.S.

Total Pancreatectomy was performed under nembutal anesthesia in 16 adult mongrel dogs after a 24-hour fast, and the depancreatized dogs were given parenteral nutrition containing fat emulsion. Serum lipids, intravenous fat tolerance and post-heparin lipolytic activity were determined and liver biopsy was done to demonstrate the presence or absence of fatty liver. The animals were divided into three groups: group A (n = 6) received fat emulsion 1 g/kg/day; group B (n = 5), fat emulsion 2 g/kg/day; and group C (n = 5), no fat emulsion. Blood levels of cholesterol and phospholipid were increased in group B, while only a mild elevation of the blood triglyceride (TG) level was noted in group A. In group C, cholesterol and phospholipid levels were decreased, and hypoglycemia was liable to occur. The rate of disappearance of blood fat (K2) was decreased two weeks after surgery in group B, but there were no significant change in the other two groups. These findings suggest that if insulin is present, the administration of fat emulsion will not cause fatty liver.

Two cases of acute fatty liver of pregnancy resulting in maternal and infant survival are described. There have only been six such cases reported previously. The two described here are unique because the diagnosis was made prepartum by an oil red O stain of a frozen section of a liver biopsy, and the patients were promptly delivered by cesarean section under spinal anesthesia. The role of early diagnosis and delivery in this disease is discussed.

Hepatic dysfunction is common in patients who receive intensive chemotherapy and it is important to determine the etiology in order to institute appropriate therapy. The role of laparoscopic liver biopsy in patients with neutropenia, thrombocytopenia, or both was evaluated as a mean of making treatment decisions and as a determinant of clinical outcome. Laparoscopic liver biopsy was performed in 29 subjects who were receiving intensive cytotoxic therapy with or without bone marrow transplantation. One to three direct-vision laparoscopic liver biopsies were performed in each patient using a Tru-cut needle during general anesthesia. Platelet concentrate transfusions were usually given before, during, and immediately after biopsy. Bleeding was controlled with spatula electrocautery. Thirty-two biopsies were obtained in 29 patients. At the time of liver biopsy, white blood cell and platelet counts ranged from 0 to 14,300/microliters (median: 2500/microliters), and 1000 to 47,000/microliters (median: 20,000/microliters), respectively. Bleeding at the liver biopsy site was readily controlled during the procedure without clinical evidence of significant bleeding; no procedure-related complications were noted and no patients required re-exploration. All biopsies were informative and the lesions observed in 32 biopsies revealed graft-versus-host disease (n = 5), hepatic candidiasis (n =1), hepatic veno-occlusive disease (n = 3), cholestasis (n = 19), hemosiderosis (n = 26), toxic injury (n = 8), hepatic steatosis (n = 4), granuloma (n = 1), viral infection (n =1), and malignancy (n = 1). Laparoscopic liver biopsy has been proven to be an effective means of assessing the cause of liver dysfunction in patients who were thrombocytopenic and immunosuppressed. The diagnosis obtained at laparoscopic liver biopsy altered therapy in nine of 29 (31%) patients.

We investigated whether alcohol pretreatment sufficient to cause fatty liver change would affect the disposition of bupivacaine after i.v. administration in pigs. Twelve male pigs (22-26 kg) were randomly divided into two groups of six each. Group A received ethanol (1 g kg-1 day-1) via an intragastric tube for 16 days. Group D received an equal volume of isocaloric dextrose 44% in water for this period. On day 17, left internal jugular and carotid cannulae were placed under thiopentone anaesthesia. On recovery from anesthesia, a blood sample was taken for the determination of liver function indices and then bupivacaine hydrochloride (1.2 mg kg-1) was administered over one minute and samples for plasma bupivacaine analysis taken from the arterial cannulae over the next five hours. Right liver lobe biopsies were taken and animals were killed under general anaesthesia. Blind evaluation of liver biopsies confirmed fatty liver changes only in alcohol-pretreated livers. Despite this there were no differences in bupivacaine disposition and liver function indices between the two groups.

In this case, the difficulty in differential diagnosis between acute viral hepatitis and acute fatty liver of pregnancy was analyzed. These 2 conditions often raise controversal question regarding the decision making on emergency anesthesia for cesarean section to avert complications and optimize management. The dilemma in which an anesthesiologist is put is whether to promise the anesthesia straightaway in the face of a demonstrable acute jaundice in pregnancy to advise a postponement of surgery until a turn for the better. In this embarrassing situation, the authors suggest that a postpronement of surgery is rational to observe the development during which both the mother and the fetus should be closely monitored. Once the necessity of a cesarean section outweighs the benefit of transitional conservative treatment, it should be performed immediately.

A 37-year-old Hong Kong Chinese female with cervical cancer was scheduled for radical hysterectomy and lymphadenectomy. Her past health was good. Pre-operatively, she was found to have a fatty liver, prolonged prothrombin time and abnormal liver function tests. Surgery was not postponed and she was anaesthetised uneventfully, using a general anaesthetic technique. The procedure lasted 4 h. Postoperatively, she developed a large pelvic haematoma and a wound infection. Her coagulation and liver function tests gradually returned to normal. No obvious medical cause for her liver dysfunction could be found. However, it emerged that she had received a 6-week course of traditional Chinese medicines prior to admission. The prescriptions contained over 60 different ingredients, some of which were known to be hepatotoxic, cytotoxic or to cause bleeding. This was the most likely explanation for her liver dysfunction.
