A randomized trial to compare single with multiple phenol injection treatment for haemorrhoids.

One hundred and twenty consecutive patients were entered into a randomized trial of single versus multiple phenol injection for the treatment of haemorrhoids. Follow-up at 3 and 12 months was available in 105 patients (56 in the single group and 49 in the multiple group). The results have shown that injection therapy, whether this be single or multiple, is an extremely effective form of therapy for patients with first or second degree haemorrhoids.

Management of pelvic sepsis after Ivalon rectopexy.

The consequences of pelvic sepsis after Ivalon rectopexy are described in four patients. Despite clear evidence of pelvic infection, reoperation was delayed by ineffective conservative measures and morbidity thereby prolonged. In three, the causative organism was Staphylococcus aureus and it is suggested that prophylactic antimicrobial regimens for intestinal organisms alone may be inadequate.

Trial of maximal anal dilatation, cryotherapy and elastic band ligation as alternatives to haemorrhoidectomy in the treatment of large prolapsing haemorroids.

A selected group of 112 patients with prolapsing haemorrhoids which had failed to respond to injections of phenol in oil or which required manual replacement after defecation, were randomly allocated treatment by haemorrhoidectomy, maximal anal dilation, elastic band ligation or cryotherapy. When results were assessed 5 weeks after treatment, haemorrhoidectomy and maximal anal dilatation were equally effective in reducing symptoms, although more physical signs remained after maximal anal dilatation; cryotherapy and elastic band ligation were less effective in both respects. When patients were followed up between 6 months and 5 years haemorrhoidectomy was found to be the most effective method. Patients in the other three groups developed recurrent symptoms requiring haemorrhoidectomy.

Severe ulcerative colitis during successful pregnancy.

A 31-year-old patient presented with fulminant colitis during the 27th week of her first pregnancy. Despite failed medical treatment, colectomy was delayed because of the gravid uterus. A healthy child was delivered at 32 weeks by caesarian section, but a postoperative ileus appeared to induce transient colonic dilatation. A colectomy was performed 10 days post-partum. Both mother and child survived.

Prophylactic systemic antibiotics in colorectal surgery.

The prophylactic value of gentamicin combined with either lincomycin or metronidazole in 52 patients undergoing colorectal surgery was investigated. The results confirmed the value of this practice. In a control group, the sepsis-rate was 48% with 1 death attributable to sepsis, compared with a sepsis-rate of 4% in the treated group. The combination of gentamicin and lincomycin was effective against sepsis but pseudomembranous colitis developed in 2 of the 14 patients treated with this combination of drugs. Lincomycin was discontinued, and when metronidazole was substituted the results were equally good and there were no toxic side-effects.

Outpatient surgery in a developing country.

233 outpatient operations were performed under general anaesthesia on Nigerian patients whose selection was not influenced by adverse social circumstances. The complication-rate was similar to that found in comparable series from the United Kingdom. The incidence of wound infection was related to the age and social circumstances of the patient and was not affected by the type of hospital in which the operation was performed.
