A total of 159 operations for the excision of a preauricular sinus carried out in 117 patients over an 8-year period were reviewed. Previous excision, the use of a probe to delineate the sinus and operating under local anaesthesia all increased the chance of recurrence. The condition recurred more often in patients who developed post-operative wound sepsis than in those who healed primarily. Means of decreasing the recurrence rate include: (1) meticulous dissection of the sinus by an experienced head and neck surgeon under general anaesthesia; (2) the use of an extended preauricular incision; (3) clearance down to the temporalis fascia to ensure complete removal of all epithelial components; (4) avoidance of sinus rupture; and (5) closure of wound dead space.

The general surgical profile of octogenarians compared with that of younger patients, and risk factors predictive of operative mortality and morbidity, were determined retrospectively using a computer database for all patients admitted between 1989 and 1993. There were 934 admissions of octogenarians and surgery was performed in 447 cases (47.9 percent). The admission rate of patients over 80 years of age increased during the 5-year period from 4.6 to 9.0 per cent, and was significantly higher than that of geriatric patients aged 65-79 years (P < 0.01). ⋯ The mortality rate of octogenarians was greater than that of younger patients (P < 0.01). Postoperative mortality and morbidity rates were 10.1 and 32.2 percent respectively. After multiple logistic regression analysis with stepwise backward elimination, an American Society of Anesthesiologists score of II-V (P < 0.01), the presence of two associated diseases (P < 0.01) and laparotomy procedures (P < 0.03) appeared to be independent risk factors for postoperative mortality and morbidity.

Sixteen laparoscopic cyst fenestrations for symptomatic adult polycystic liver disease (APLD) were performed in 13 women, including four patients who had had previous attempts at treatment (percutaneous sclerotherapy in two and fenestration via a laparotomy in two). The median number of cysts deroofed was 32 (range 18-58) during the 13 primary procedures. There was no in-hospital death. ⋯ Two patients underwent three repeat laparoscopic fenestrations, at which time perihepatic adhesions were rare and no complication occurred. Because repeat procedures may be performed, laparoscopic fenestration appears to be useful for the treatment of symptomatic APLD. However, it is less effective than fenestration at open surgery or liver resection and should be employed only in patients with predominantly large cysts.

A retrospective study was carried out of patients from a single institution over a 30-year period. Thirty-one patients presented with 33 fistulas, four non-enteric and 27 enteric. In 25 of 27 patients with a prosthesis-related enteric fistula gastrointestinal bleeding was present. ⋯ In-hospital mortality decreased from six of eight patients before 1970, to seven of ten between 1971 and 1980, and to four of 13 after 1981. In the long term, patients treated with an extra-anatomic reconstruction had a poorer prognosis than those treated by in situ reconstruction. This experience shows that diagnostic tests often fail to reveal a prosthesis-related fistula and that mortality can be substantially reduced by early exploration in patients with negative diagnostic studies.

The propensity of pleomorphic adenomas to recur is generally attributed to the biological nature of the tumour, and surgery close to the capsule is perceived as undesirable. At the Christie Hospital, Manchester, between 1947 and 1992, 475 tumours arising within the superficial portion of the parotid gland were treated by two surgical techniques: extracapsular dissection (380 patients) and superficial parotidectomy (95). ⋯ There was no difference between the treatment groups in the incidence of permanent facial nerve injury (2 versus 1 per cent respectively). This study demonstrates that dissection in close proximity to the tumour is possible without inducing recurrence and that in practice the microinvasion of the capsule by tumour buds has limited clinical significance.
