Objective: To review the yield and indications of colonoscopy in a surgical unit at the Prince of Wales Hospital, the result of which may help to select future patients for colonoscopy.
Method: The ...records of 869 patients undergoing elective colonoscopy at the Prince of Wales Hospital within an 18‐month period were reviewed retrospectively. Exclusion criteria included the following: a personal history of colorectal malignancy or polyps, tumours or polyps detectable on rectal examination or rigid sigmoidoscopy, a positive physical examination suggestive of gastrointestinal malignancies, anaemia or positive faecal occult blood.
Results: Per rectal bleeding was the most common indication for colonoscopy. Complete colonoscopy rate was 93.7% and abnormalities were reported in 338 patients. Forty‐three patients were found to have cancer whereby age, duration of symptoms, blood mixed with stool and abdominal pain were identified as independent predictive factors. Neoplastic polyps were confirmed in 200 patients. Old age and being male were the only factors predictive of neoplastic polyps.
Conclusion: Although the majority of patients present with typical haemorrhoidal bleeding, colonoscopy should be considered seriously for elderly patients, especially those who are male.

Objective: To elucidate if the course of acute appendicitis is influenced by the variable positions of the appendix. The appendix positions were divided into two groups: (i) the anterior group, which ...included the anterior, the pelvic and the paracaecal positions; and (ii) the posterior group, which included the retrocaecal and retroileal positions.
Method: The hospital records of 161 patients who underwent appendectomy for acute appendicitis from January 2000 to June 2001 at Prince of Wales Hospital were reviewed retrospectively.
Results: Clinicians’ delay in reaching the diagnosis was longer in the posterior group (9.9 h vs 5.8 h; P=0.043). However, complicated appendicitis (gangrenous changes, perforation or abscess formation) was not associated with the appendix location (P = 0.078). The median operating time for laparoscopic appendectomies lasted longer in the posterior group (77.5 min vs 60 min; P = 0.02). These patients also had a longer hospital stay (6 days vs 4 days; P = 0.049). No difference was observed among patients who underwent open surgery.
Conclusion: Appendices in the ‘hidden’ position did not translate into a higher incidence of complicated appendicitis or postoperative complications except for the slightly longer hospital stay in patients treated by laparoscopy. Therefore, we concluded that the location of appendices does not affect the clinical course of appendicitis in the locality studied.
