  • Title: Technique and clinical results of endorectal surgery.
    Author: Said S, Huber P, Pichlmaier H.
    Journal: Surgery; 1993 Jan; 113(1):65-75. PubMed ID: 8417491.
    Abstract:
    At the Surgical Department of the University of Cologne, a new system has been developed for transanal endoscopic surgery that allows all the conventional surgical techniques within the entire rectal cavity. The method has been in clinical use since 1983. The main indication is the removal of sessile adenomas. Early rectal carcinomas with favorable histologic grading (grades 1 and 2) and staging (Mason I and II) are also suitable for the method. Advanced cancers can also be removed endoscopically in one session, but we perform local excisions of advanced cancers only in cases in which the patient is unwilling to undergo extensive surgery. During the period from July 1983 to December 1990, this method has been employed on 233 patients in 251 cases. The intraoperative and postoperative course of 236 (94%) operations out of 251 was free from any complications. Early postoperative complications consisted of intraperitoneal perforations (five cases), rectovaginal fistulas (four cases), hemorrhages (four cases), and death as a result of cardiopulmonary failure (two cases). The recurrence rate of adenomas is 4.9%. Endorectal surgery allows endoscopic local transanal excision of large adenomas and early cancers with minimal morbidity and excellent presentation of specimens for complete histologic analysis.
