Resected specimen evaluation,anorectal manometry,endoanal ultrasonography and clinical follow-up after STARR procedures

AIM:To investigate stapled transanal rectal resection (STARR) procedures as surgical techniques for obstructed defecation syndrome (ODS) by analyzing specimen evaluation,anorectal manometry,endoanal ultrasonography and clinical follow-up.METHODS:From January to December 2007,we have treated 30 patients.Fifteen treated with double PPH-01 staplers and 15 treated using new CCS 30 contour.Resected specimen were measured with respect to average surface and volume.All patients have been evaluated at 24 mo with clinical examination,anorectal manometry and endoanal ultrasonography.RESULTS:Average surface in the CCS 30 group was 54.5 cm2 statistically different when compared to the STARR group (36.92 cm2).The average volume in the CCS 30 group was 29.8 cc,while in the PPH-01 it was23.8 cc and difference was statistically significant.The mean hospital stay in the CCS 30 group was 3.1 d,while in the PPH-01 group the median hospital stay was 3.4 d.As regards the long-term follow-up,an overall satisfactory rate of 83.3% (25/30) was achieved.Endoanal ultrasonography performed 1 year following surgery was considered normal in both of the studied groups.Mean resting pressure was higher than the preoperative value (67.2 mmHg in the STARR group and 65.7 mmHg in the CCS30 group vs 54.7 mmHg and 55.3 mmHg,respectively).Resting and squeezing pressures were lower in those patients not satisfied,but data are not statistically significant.CONCLUSION:The STARR procedure with two PPH-01 is a safe surgical procedure to correct ODS.The new Contour CCS 30 could help to increase the amount of the resected tissue without differences in early complications,post-operative pain and in hospital stay compared to the STARR with two PPH-01 technique.
