Establishing a teaching unit in laparoscopic radical prostatectomy: An Australian experience

Objective:

The aim of this project was to examine the role of surgical mentorship on the perioperative and oncological outcomes of patients undergoing laparoscopic radical prostatectomy (LRP) performed by two urologists inexperienced in the procedure.

Methods:

Forty-one (41) consecutive LRP cases were performed for clinically localised prostate cancer between December 2006 and June 2008 at a single centre. The surgical mentor approach was used with an experienced LRP surgeon being present for all cases that were performed by two urologists training in LRP. Data was retrospectively reviewed to assess morbidity and oncological outcomes of patients undergoing LRP by the team of trainees.

Results:

No LRP cases were converted to open and no major intraoperative complications were noted. Mean intraoperative blood loss was 493 ml (range 150–1000 ml) with the mean operative time being 220 minutes (range 100–315 minutes). The overall positive margin rate was only 12% (five out of 41 cases).

Conclusion:

LRP teaching units can be established with appropriate mentor supervision and can result in good oncological outcomes and minimal morbidity that compares favourably to robotic-assisted radical prostatectomy (RARP).

Insurance and the risk of ruptured appendix in the adult

BACKGROUND

Disparities in medical care related to the insurance status of patients have been reported. A retrospective analysis was performed to examine the insurance-related differences in the risk of appendiceal perforation in the Prince of Wales Hospital (POWH), New South Wales.

METHODS

Computerized data of 1179 patient years who had a diagnosis of appendicitis and were admitted to the POWH over the preceding 10 years were examined. The outcome measure was appendiceal perforation. Patient variables examined were insurance status, sex, age, and socio-economic status (SES). Three hundred patients over the same period were identified who had an appendicectomy but not appendicitis. Multiple logistic regression and Fisher's exact test were used for statistical analysis.

RESULTS

The overall perforation rate in 1179 patients was 17%. The only factor that was related to an increased risk of perforation was age over 50 years (odds ratio (OR) 1.57; 95% confidence interval (CI) 1.04-2.53). Sex, insurance status or SES were not associated with a higher risk of perforation. The overall rate of negative appendicectomy was 20% (300 of 1479 patients), and the rate was higher in the uninsured patients (22 vs 17%, P = 0.014, Fisher's exact test).

CONCLUSIONS

Lack of health insurance was not associated with an increased incidence of appendiceal perforation at the POWH. Age over 50 years was identified as the only risk factor for appendiceal perforation. The lower negative appendicectomy rate in the insured group may be because of better diagnostic ability of consultants compared to registrars.
