Intesive histological and biomechanical examinations have shown that the smooth muscles of the human gastrointestinal tract can be freely transplanted to take over the functions of a sphincter. In this study it has been shown how conventional colostomy can be converted into a continent one with the aid of a sphincter plasty. The operational technique, especially encircling the rectum, provides protection at the same time against prolapse of the anus praeternaturalis.
深入的组织学和生物力学检查表明，人类胃肠道的平滑肌可以自由移植以接管括约肌的功能。在这项研究中，已经表明如何借助括约肌成形术将传统的结肠造口术转变为可控性结肠造口术。手术技术，特别是围绕直肠的操作，同时提供了防止肛门脱垂的保护。
