Outcomes
Primary outcome [1] 266579 0
To determine if Rectogesic glyceryl trinitrate is beneficial post stapled haemorrhoidectomy

The patients were interviewed within 48 hrs by a clinical nurse to assess that they have recovered satisfactorily and that they were compliant in postoperative care including medications prescribed. Patients completed visual analogue scores on maximum pain, average pain and satisfaction, administered by an independent observer blinded to the randomization. Those with persistent problems were reviewed at 2 monthly intervals until they were symptom free. All patients agreed to a telephone interview conducted again at the closure of the study and clinical review was invited as required.
Data was analysed on an intention-to-treat basis. It was estimated that 100 patients in each arm would provide a 0.8 power to detect a 10% difference in pain scoring. Patients who failed to complete the program were treated as missing. Numerical data are presented as mean and range, or median and interquartile range (IQR), depending on the distribution. Comparisons between characteristics were calculated using 2 tests and 2 tests for trend, the nonparametric Wilcoxon tests, and t tests. Statistical analyses were conducted using SPSS for Windows version 18 (SPSS Inc, Chicago, IL). A significance level of 0.05 was adopted a priori.
