RESUMEN
OBJECTIVES: To highlight important aspects and paradigms in the management of paediatric cholesteatoma in a developing world setting. METHODS: A retrospective audit was conducted of paediatric cholesteatomas that underwent tympanomastoid surgery between 2008 and 2012 at the Red Cross War Memorial Children's Hospital in Cape Town. The following was audited: initial presentation; cholesteatoma complications; types of surgery, intraoperative findings and outcomes of surgery in terms of hearing, otorrhoea and recidivism; and the reliability of follow-up and how this might influence the type of surgery. RESULTS: Fifty-seven children aged 2-13 years with 61 cholesteatomas (4 bilateral) were reviewed. Fifty-five mastoidectomies were done; 11% presented with complicated cholesteatoma. Referrals from primary care were significantly delayed (>6 months) in 76%. Canal wall down surgery was done in 71%. Forty-five percent had improved hearing (within 15dB of better hearing ear) and a further 15% had no or only mild hearing loss. Ossicular chain involvement and ossicles encased in inflammatory tissue were associated with poorer hearing outcomes. Sixty-four percent of ears remained dry. Forty-five percent of the canal wall up, and 23% of canal wall down mastoidectomies had recidivism. Twenty-six percent of patients were lost to follow-up. CONCLUSIONS: Children are likely to present with advanced cholesteatoma with ossicular chain involvement. The children present with high rates of complications, poor pre-operative hearing and have high recurrence rates post-surgery. Referral from primary health care is delayed. Canal wall down procedures may be appropriate in a setting where patient follow-up is unreliable and access to operating theatre is limited.

The introduction of new imaging techniques has markedly improved the diagnosis of hepatobiliary disorders. Due to their anatomic situation, a substantial percentage of malignancies located near the hilus is not suitable for surgical management. We discuss an effective palliative intervention to relieve jaundice. In many instances drainage is a superior choice when biliodigestive anastomoses are not technically feasible and palliative resection carries a high complication rate. We present an irrigatable exo-endodrainage method employing a modified port-a-cath system as a new alternative. In four patients, all older than 75 years, this system was implanted because of jaundice due to unresectable malignant stenosis of the extrahepatic bile duct. One patient (80 years old) died of pre-existing acute necrotizing pancreatitis, although hyperbilirubinemia was found to decrease on the 7th postoperative day. The other three patients showed complete normalization of their bilirubin levels and their port-a-cath systems remained open until their death (at 3 weeks, 6 months and 7 months respectively).

A major complication of abdominoperineal rectum excision for rectal or anal carcinoma is local wound infection. The main reason for this infection is that systemically administered antibiotic prophylaxis does not reach sufficiently high concentrations of antibiotic in the tissue of the sacroperineal wound. Since gentamicin-polymethylmethacrylate (PMMA) in the form of chains of beads has been confirmed as a useful tool in the treatment of local infection in bone and soft tissue surgery, we have evaluated its effect on the abdominoperineal rectum excision in a prospective, randomized trial. Forty-four patients with rectal or anal carcinoma entered the study. Only patients with stage Dukes D were excluded from the trial. Following randomized selection, the patients were treated either with local gentamicin and drainage (Group A) or drainage alone (Group B), using the Lloyd-Davies procedure. The two groups were comparable regarding age, sex, tumor stage and level, and risk factors predisposing for an infectious complication (anemia, nutritional status, blood transfusion). The postoperative mortality rate was 0% in both series. Analysis of local perineal wound healing revealed a statistically significant higher percentage of primary wound healing in Group A than in Group B (87% versus 46%; p less than 0.01). This led to a significantly shorter hospitalization period for patients in Group A (p less than 0.01). Gentamicin-PMMA chains have been demonstrated to exert a favorable effect on local wound healing and the postoperative outcome of patients with abdominoperineal rectum excision.
