Rare pulmonary complications after transarterial chemoembolisation for hepatocellular carcinoma: two case reports.

We report two rare cases of acute pulmonary complication after transarterial chemoembolisation for inoperable hepatocellular carcinoma. Both cases involved a large tumour and hepatic vein invasion. The first patient, a 27-year-old man, died of pulmonary tumour embolism 4 days after transarterial chemoembolisation. Acute dyspnoea developed in the second patient, a 63-year-old man, following the procedure due to pulmonary oil embolisation and chemical pneumonitis. The chest condition of this patient improved, but he subsequently died of liver failure 3 weeks later. Our cases illustrate the point that if locoregional treatment is offered as a palliative treatment, patients with hepatic vein invasion should be warned of the possible complications of massive tumour embolism, pulmonary oil embolisation, and subsequent death.

A blinded clinical trial comparing conventional cleansing enema, Pico-salax and Golytely for barium enema bowel preparation.

UNLABELLED: An evaluator-blinded randomized clinical trial was undertaken to assess the effectiveness and patient acceptance of three bowel cleansing regimens: conventional cleansing enema, Pico-salax and Golytely. PATIENTS AND METHODS: One hundred and fifty patients, referred for barium enema examination, were allocated to one of the three regimens. Both the radiographers and the radiologists did not know the method of preparation. Radiographers were requested to enter the patients' data, the number of bowel openings, the patients' comments of the preparation and side effects. Films were reviewed independently by two experienced radiologists for the degree of bowel cleanliness and quality of barium coating. RESULTS: The mean (standard deviation) of bowel opening frequency for the cleansing enema, Pico-Salax and Golytely were 3.6(4.4), 8.3(4.8) and 7.1(4.2), respectively, with less bowel opening in the cleansing enema. There was less nausea associated with the cleansing enema (P = 0.006), more vomiting with Golytely (P = 0.008), less abdominal fullness with Pico-salax (P = 0.0006), less anorectal irritation with Golytely (P = 0.025), and no difference in the abdominal pain amongst three groups. There was no statistically significant difference in the number of bowel openings between the groups. Patients found that Pico-salax tasted better than Golytely (P = 0.0094) and Golytely was less accepted in the amount of fluid intake (P = 0.0018 and P < 0.0002 comparing Golytely with the cleansing enema and Pico-salax). Chi-squared testing showed no statistically significant difference in bowel cleanliness and quality of barium coating among the three preparations. CONCLUSIONS: There was no difference in the effectiveness of the three regimens. Pico-salax seems the most acceptable because it has the fewest side effects.
