Non-operative arterial embolisation in primary liver tumours.

Three patients with primary hepatic tumours were treated by selective arterial embolisation with gelatin-foam fragments to induce necrosis. In the two with histologically proved hepatocellular carcinoma ultrasonography suggested that necrosis had been induced, as did the rapid initial falls in serum alpha-fetoprotein concentration by 95 and 81% of the original values respectively. Treatment was continued with a course of adriamycin, and both patients remained well and symptom free at 10 and 12 months. In the third patient, who had an expanding and highly vascular benign hepatic adenoma associated with use of a contraceptive pill, embolisation obliterated the tumour mass. Tumour embolisation should be regarded as only the first step in managing hepatocellular carcinoma and as a means of reducing appreciably the viable tumour mass before chemotherapy. It may be used as the primary and definitive treatment in patients with benign liver tumours.

Emergency Endoscopy after Gastrointestinal Haemorrhage in 50 Patients with Portal Hypertension

Endoscopy was carried out in 50 patients with oesophageal varices within 24 hours of a major haematemesis or melaena. Sources of bleeding were identified in 42 of the cases and in only 19 patients was bleeding due to oesophageal varices. Bleeding from gastric varices was present in 11 patients, and a variety of acute and chronic lesions made up the remainder. In contrast with previous series haemorrhage from erosive gastric lesions was seen in only five patients and was no more common in 23 patients with alcoholic cirrhosis than in the group as a whole.

TREATMENT OF HIGH BILEDUCT CARCINOMA BY INTERNAL RADIOTHERAPY WITH IRIDIUM-192 WIRE

Abstract Eight patients with high bileduct carcinoma were treated by a new technique of internal radiotherapy with iridium-192 wire after biliary drainage had been established. Seven patients had satisfactory initial biliary drainage, and six patients are still alive 11 months (median time) after treatment. The procedure produced no systemic side-effects and it prolonged survival in patients in whom restoration of bile drainage had been satisfactory.

Internal biliary drainage and local radiotherapy with iridium-192 wire in treatment of hilar cholangiocarcinoma

Curative surgery is not possible in the vast majority of patients who present with hilar cholangiocarcinoma. Palliative therapy to relieve jaundice, either at laparotomy or percutaneously, is therefore necessary. The mean survival of these patients is of the order of 8.5 months (Wheeler et al., 1981). We report a significant increase in mean survival to 16.8 months in patients treated with internal biliary drainage when combined with local irradiation to the tumour with iridium-192.

Biliary complications following orthotopic liver transplantation

The gall-bladder conduit anastomosis (choledocho-cholecysto-choledochostomy) has been the most frequently used technique for the biliary tract anastomosis in the Cambridge/Kings College Hospital joint liver transplantation programme since 1976. Cholangiograms and interventional biliary procedures performed over a 3 year period were reviewed retrospectively. Seventy-six of 148 patients managed post-operatively at Kings College Hospital were studied (79 transplants). Cholangiograms were abnormal in 63 (80%) transplants with biliary strictures; inspissated bile formation, bile leak and T-tube malposition occurring in 50, 23, 14 and three transplants respectively. Anastomotic strictures occurred most frequently, predominantly at the proximal anastomosis, and the presence of inspissated bile and the T-tube in relation to these contributed towards subsequent biliary obstruction. Non-anastomotic strictures in the donor biliary tract were associated with a high position of the T-tube tip at or above the liver hilum. Saline irrigation of the bile ducts for inspissated bile or its removal via the endoscope were effective measures in the management of biliary obstruction but percutaneous balloon dilatation and endoscopic stent insertion for biliary strictures were found to have a limited role.

Acute inflammation of the breast — the role of breast ultrasound in diagnosis and management

Twenty female patients aged between 24 and 69 years were referred for breast ultrasound (US) examination between June 1989 and June 1990, with clinical suspicion of a breast abscess. Six were currently lactating. Initial US examination confirmed the presence of an abscess collection in nine out of 20 patients. Seven of these subsequently had surgical incision and drainage. Two settled on medical treatment. No abscess was detected on initial US examination in the remaining 11 patients who were treated conservatively with oral antibiotics. One patient, who had markedly dilated ducts on her initial US examination, remained symptomatic. Follow-up US demonstrated a small fluid collection, which within 7 days developed into a large multiloculated abscess requiring surgical drainage. We feel that US is very useful in accurately demonstrating the presence or absence of an abscess collection in the acutely inflamed breast.

Treatment of bleeding oesophageal varices by infusion of vasopressin into the superior mesenteric artery

Seventeen patients bleeding from oesophageal varices were treated by continuous infusion of vasopressin through a catheter inserted percutaneously and positioned in the superior mesenteric artery and in two other patients catheterization proved technically impossible. Bleeding was completely controlled on only four out of 18 occasions in the 17 patients treated. In seven patients, bleeding was controlled for two or more days but then recurred although the infusion was continued with an increased dose of vasopressin. There was a high incidence of complications, including bleeding from the site of catheter insertion in the groin and septicaemias. Sengstaken balloon tamponade and oesophageal transection had to be used to control bleeding in some patients but only six out of 17 survived to leave hospital.

Detection and grading of oesophageal varices by fibre-optic endoscopy and barium swallow with and without Buscopan

Detection of oesophageal varices is important in the diagnosis of portal hypertension. We have, therefore, compared the results of fibre-optic endoscopy and barium swallow in 56 patients with chronic liver disease. Oesophageal varices were graded as small, moderate or gross by independent observers for each technique. In 12 patients varices were not detected by either method, and in six cases varices were detected by endoscopy when the barium swallow was negative. In 15 of the remaining 38 patients varices were found to be one grade larger at endoscopy than on barium swallow. Since it is possible that varices appear larger at endoscopy because of the Buscopan (hyoscine N-butyl bromide) used as a relaxant, we carried out barium examinations after Buscopan 20 mg i.v. in 23 of the patients. In eight cases varices were one grade larger after Buscopan than on the standard barium swallow, and in two were only detected after Buscopan had been given. Eight cases negative after Buscopan were also negative at endoscopy. Although emergency endoscopy has particular value in locating the site of bleeding in patients with portal hypertension and acute gastrointestinal haemorrhage, the results of the present study suggest that a barium meal with Buscopan is as accurate as endoscopy in the detection of oesophageal varices.

Adoptive immunotherapy administered via the hepatic artery and intralesional interleukin-2 in hepatocellular carcinoma

We assessed the feasibility of using lymphokine-activated killer cells (adoptive immunotherapy) with infusions of interleukin-2 when given regionally in three patients with unresectable primary hepatocellular carcinoma (PHC). In 2 patients, 2 cycles, which included a bolus of LAK (10(7) to 10(8) cells followed by a 4-hourly infusion of IL-2 were administered via selective arterial catheterization of the hepatic artery. One further patient received 3 cycles of IL-2 alone by direct intralesional and perilesional injections. Minimal toxicity was observed and side effects such as fever were comparable to those observed with systemic infusions of IL-2 alone. Serial alpha-fetoprotein (AFP) levels initially fell but subsequently rose within 2 to 4 weeks of therapy. AFP levels had not reached pre-treatment values at 4 months in 2 patients, 1 of whom was alive and well at 15 months follow-up.

Percutaneous cholangiography in prolonged jaundice of childhood.

Fine-needle percutaneous cholangiography has been carried out on a selected group of 22 infants and children who were jaundiced from a variety of causes. The technique has aided both the diagnosis and surgical management of the patients and has been free from complications.
