Randomized Controlled Trial Clinical Trial
Adjuvant oral chemotherapy to prevent recurrence after curative resection for hepatocellular carcinoma.
Adjuvant oral chemotherapy was studied in 67 patients with stage II hepatocellular carcinoma who underwent curative resection between May 1988 and December 1990. Patients were stratified into two groups according to preoperative liver dysfunction: 55 had stage I disease (mild dysfunction) and 12 had stage II (moderate dysfunction). A randomized controlled study of postoperative oral administration of 1-hexylcarbamoyl-5-fluorouracil (HCFU) was conducted in each group. ⋯ Cumulative survival and recurrence-free survival rates of patients with stage I disease in the treatment group were higher (P = 0.08 and P = 0.04 respectively) than those in the control group. However, in patients with stage II disease no significant difference was observed (P = 0.77 and P = 1.0 respectively). This study suggests that the potential benefits of HCFU on tumour recurrence should be weighed against the risk of adverse reactions in patients with mild liver dysfunction.

Randomized Controlled Trial Clinical Trial
Symptomatic outcome 1 year after laparoscopic and minilaparotomy cholecystectomy: a randomized trial.
In a randomized controlled trial, 299 patients were sent a symptoms questionnaire 1 year after laparoscopic (n = 151) or minilaparotomy (n = 148) cholecystectomy for symptomatic cholelithiasis. The response rate to the questionnaire from contactable patients was 86 per cent. In both groups, at least 90 per cent of patients reported that their symptoms were improved, and at least 93 per cent rated the success of their operation as 'excellent', 'good', or 'fair'. ⋯ The only difference between treatment groups was that a higher proportion of patients who underwent minilaparotomy reported heartburn (35 per cent versus 19 per cent, P = 0.005). Patients who reported a 'poor' outcome were more likely to have suffered a postoperative complication, had lower quality of life scores, and higher anxiety and depression scores. Both laparoscopic and minilaparotomy cholecystectomy result in symptomatic benefit in at least 90 per cent of patients with symptomatic cholelithiasis.

Randomized Controlled Trial Clinical Trial
Pain relief after inguinal hernia repair: a randomized double-blind study.
A randomized double-blind study was undertaken using 0.5 per cent bupivacaine ilioinguinal field block and oral papaveretum-aspirin tablets to assess pain relief after hernia surgery. A consecutive series of 200 men undergoing repair of a unilateral inguinal hernia underwent random allocation into one of the four groups to receive: bupivacaine and papaveretum-aspirin (group 1), bupivacaine and oral placebo (group 2), saline and papaveretum-aspirin (group 3), or saline and oral placebo (group 4). Patients were prescribed postoperative opiates to be given on demand. ⋯ Patients in group 1 reported significantly less pain, required less additional opiates and had better mobility than those in group 4 (pain score P < 0.001 at 6 h and P = 0.002 at 24 h) and group 3 (P = 0.002 for pain and mobility scores at 6 h). Bupivacaine alone provided good immediate postoperative pain relief (P = 0.002 group 2 versus group 4 at 6 h). The combination of bupivacaine and papaveretum-aspirin provided the best results and is suitable for day-case postoperative analgesia.

Randomized Controlled Trial Clinical Trial
Prospective randomized study of surgical morbidity following primary systemic therapy for breast cancer.
The influence of primary systemic therapy in treating operable breast cancer on postmastectomy morbidity rates was investigated. The contribution of other risk factors was assessed by multiple logistic regression. Seventy-nine eligible patients were randomly allocated, 39 to undergo immediate modified radical mastectomy, and 40 to receive initial cytotoxic or endocrine treatment followed by mastectomy. ⋯ Age, smoking, immediate breast reconstruction and the type of primary systemic treatment given were not independent predictors of complication risk. Obesity emerged as a significant risk factor for postmastectomy complications (P = 0.015). Primary systemic therapy does not increase the rate of morbidity after mastectomy.

Randomized Controlled Trial Clinical Trial
Closure of midline laparotomy incisions with polydioxanone and nylon: the importance of suture technique.
The healing of midline laparotomy incisions closed with a continuous suture of nylon or second-generation polydioxanone was evaluated in a randomized clinical trial. The effect of suture technique, reflected in the suture length to wound length ratio, was also assessed. All patients who underwent abdominal surgery through a midline incision were included except those with incisional hernia after previous midline operation. ⋯ There was a significant correlation between the hernia rate and the suture to wound length ratio for both materials (P < 0.001). These results indicate that suture of midline laparotomy wounds is as safe with polydioxanone as it is with nylon. Incisional hernia is associated more with suture technique than with the material used.
