Extended hepatectomy for hepatocellular carcinoma.

The results of extended hepatectomy in 25 patients with hepatocellular carcinoma performed over a 16 year period have been reviewed, analysed and compared with those of 144 patients who underwent lesser liver resection. Five left and 20 right extended hepatectomies were performed for tumours ranging from 3 to 20 cm in diameter. Seventeen (68 per cent) of the patients had non-cirrhotic livers. The major postoperative complications were: haemorrhage in five cases, major bile duct injury in three, subphrenic abscess in two, liver failure in one and wound dehiscence in one. The 30-day (operative) mortality rate was 12 per cent and the median survival duration, including operative mortality, was 9.7 (range 0.2-32.1) months. The survival rate was 46 per cent at 1 year, 33 per cent at 2 years and 22 per cent at 3 years. The morbidity, mortality and survival data of extended hepatectomy were comparable with the results of lesser hepatic resections for hepatocellular carcinoma. We conclude that extended hepatectomy is a worthwhile operation for large hepatocellular carcinomas and a viable alternative to liver transplantation.

Abdominal tuberculosis.

Forty-two cases of abdominal tuberculosis seen between June 1984 and June 1988 at Amiri Hospital in Kuwait were reviewed retrospectively. The clinical diagnosis was correct in only 35%. Nine patients presented as an emergency, but in none was a diagnosis of tuberculosis considered. Abdominal pain and tenderness were the commonest clinical findings; "doughy abdomen" and a mass in right iliac fossa were uncommon. Thus, symptoms were vague, signs nonspecific and investigations nonpathognomonic. In spite of this, abdominal tuberculosis should be considered in any patient who has obscure abdominal symptoms, weight loss and lethargy. Laparoscopy and colonoscopy with biopsy for histologic and bacteriologic study led to a definitive diagnosis in 66% of cases, obviating the need for exploratory laparotomy in many. Histologic examination was the surest way to establish the diagnosis.

Falls in hemoglobin saturation during ERCP and upper gastrointestinal endoscopy.

Fiberoptic endoscopy is practiced everyday in the field of gastroenterology and, for diagnostic purposes, carries a risk of complications and an estimated mortality of 1:5,000, which is multiplied several times during interventional procedures. Half of these complications have a cardiopulmonary origin which may be anticipated by the use of pulse oximetry to measure hemoglobin saturation (SaO2). We studied 132 patients undergoing diagnostic or procedural endoscopic retrograde cholangiopancreatography (ERCP) under sedation, and 51 undergoing esophagogastroduodenoscopy (EGD) without sedation. In the ERCP group, SaO2 fell from 95.7 +/- 2.4% (mean +/- standard deviation) to 88.9 +/- 6.4% (p less than 0.001) with a corresponding rise in pulse from 95 +/- 19 to 116 +/- 18/min (p less than 0.001) followed by recovery. The largest falls followed positioning of the endoscope (rather than following administration of the sedative or the procedure), particularly during introduction of the endoscope within 1 minute of administering diazemuls (diazepam). The EGD group also had a fall in SaO2 (97.3 +/- 1.9% to 93.9 +/- 3.3%, p less than 0.001), although the patients were younger and undergoing shorter examinations. Again, the largest falls occurred 1 minute after introduction of the endoscope. In subgroups of patients undergoing ERCP, analysis of respiratory patterns using spectral techniques and electrocardiogram during endoscopy (n = 25), or peripheral perfusion using transcutaneous oximetry and laser Doppler velocimetry (n = 12) was undertaken. No correlations were found in relation to changes in SaO2. The cause of the fall in SaO2 during endoscopy is multifactorial.(ABSTRACT TRUNCATED AT 250 WORDS)
