The underlying anatomical and pathophysiological changes of ODS are complex. However, intra-rectal intussusception and rectocele are frequently found in patients with ODS and both are thought to play an important role in the pathogenesis of ODS. With the development of evaluation methods in anorectal physiology laboratories and radiology studies, a great variety of new operative procedures, especially transanal procedures, have been invented to treat ODS. However, no procedure has been proved to be superior to others at present. Each operation has its own merits and defects. Thus, choosing appropriate transanal surgical procedures for the treatment of ODS remains a challenge for all surgeons. This review provides an introduction of the current problems and options for treatment of ODS and a detailed summary of the essential assessments needed for patient evaluation before carrying out transanal surgery. Besides, an overview of the benefits and problems of current transanal surgical procedures for treatment of ODS is summarized in this review. A report of clinical experience of some transanal surgical techniques used in the authors' center is also presented.展开更多

Although it is a safe and effective treatment for obstructive defecation syndrome, still data on long-term follow-up are missing. Methods: From January 2010 to July 2014, 46 consecutive patients undergoing STARR using the CONTOUR® TRANSTAR™ device, shortly named TRANSTAR (transanal stapler assisted resection), were prospectively followed. Recurrence rate, quality of life (Patient Assessment of Constipation-Quality of Life (PAC-Qol)) and complication were documented at baseline, 12 and 24 months after operation. Two subgroups of patients were compared to assess the impact of resection length on outcome. Results: We included 46 patients (89% female) in the study. The mean age was 65 ± 16 years and the duration of the operation was 48 ± 4 min. Total PAC-QoL score improved from 2.0 (SD 0.3) to 0.9 (1.4) after 12 months, but deteriorated to 1.2 (0.3) after 24 months (p < 0.001 for both comparisons). Complications were noted in 7% of the patients: Urinary retention (2 patients), postoperative bleeding (1 patient). No major complications or mortality were seen. After one year, we had one prolapse recurrence and after 24 month we had another. There was no significant relation between the length of the specimen and the improvement of life quality. Conclusions: The STARR procedure seems to be a safe and fast therapeutic option for patients with ODS and/or rectal prolapse. It is a tailored transanal full-thickness rectal resection improving the patients’ quality of life still two years after the operation.展开更多
