Surgical management of chronic inguinal pain syndromes - Liespijn

on chronic pain. Presence of chronic pain was the dependent variable whereas age,follow-up duration, priority of CD, number of Pfannenstiel incisions, numbness, and scarlength were used as independent variables. The multivariate model was constructedby backward stepwise selection with entry testing based on significance of scorestatistics. CD priority was assessed in a multivariate analysis with CD patients only. Thelimit of statistical significance was set at p=0.05 (two-sided). Analysis was performedusing the Statistical Package for the Social Sciences (SPSS), Windows version 12.0.1RESULTSFigure 1 Schematic drawing in questionnaire that women used for pain localisation with corresponding results.(n=205, missing data in 18 patients). Pain distribution showed in percentages: at the right end of the scar, left end, entirescar, middle of the scar and diffusely in the lower abdomen. 30 patients reported pain at both lateral ends of the scar.Mean incision length, cm (SD= standard deviation) = 13.5 (3.4).QuestionnaireA total of 872 CD’s and 95 AH’s using a Pfannenstiel approach was performed during thetwo year time period. A patient flow chart is depicted in Figure 2. There were 866 post-Pfannenstiel patients who were eligible for this study that received a questionnaire.Eventually, 690 patients returned the questionnaire (response rate 690/866, 80%).Demographic and clinical details of both responders as well as non-responders arelisted in table 1. Except for priority of CD, these two groups were comparable. A CD wasperformed in more than 90% of the women, and an average CD patient was approximately15 years younger compared to an abdominal hysterectomy patient (35 vs. 50yrs, p
