Multicenter Study Comparative Study
Diagnostic accuracy of the faecal immunochemical test for colorectal cancer in symptomatic patients: comparison with NICE and SIGN referral criteria.
The diagnostic accuracy of the faecal immunochemical test (FIT) at a 100 ng/ml threshold for colorectal cancer (CRC) was compared with National Institute for Health and Care Excellence (NICE) and the Scottish Intercollegiate Guidelines Network (SIGN) referral criteria. ⋯ Our study suggests that FIT is more accurate for the detection of CRC than the current NICE and SIGN referral criteria in symptomatic patients referred for colonoscopy.

Randomized Controlled Trial
Randomized single-blind clinical trial of intradermal methylene blue on pain reduction after open diathermy haemorrhoidectomy.
Open haemorrhoidectomy has been associated with considerable postoperative pain and discomfort. Perianal intradermal injection of methylene blue has been shown to ablate perianal nerve endings and may bring about temporary pain relief after haemorrhoidectomy. We hypothesized that the administration of intradermal methylene blue would reduce postoperative pain during the initial period after surgery. ⋯ Perianal intradermal injection of methylene blue was useful in reducing the initial postoperative pain of open haemorrhoidectomy.

Comparative Study
Quality of total mesorectal excision and depth of circumferential resection margin in rectal cancer: a matched comparison of the first 20 robotic cases.
There are concerns about the impact of robotic proctectomy on the quality of total mesorectal excision (TME) and the impact of laparoscopic proctectomy on the depth of the circumferential resection margin (CRM). The aim of this study was to compare the first 20 consecutive robotic proctectomies performed in our unit with matched series of open and laparoscopic proctocolectomy performed by the same surgeon. ⋯ The study reports no statistically significant difference between open and laparoscopic techniques in the quality of TME during the learning curve of robotic proctectomy for rectal cancer and demonstrates an improved CRM.
