  • Title: [Minimally invasive surgery of the rectum].
    Author: Said S, Pichlmaier H.
    Journal: Zentralbl Chir; 1992; 117(9):489-94. PubMed ID: 1441787.
    Abstract:
    Low precision of transanal techniques, their limited area of application and high rate of complications of extensive surgical techniques led to the development of an endoscopic surgical system. Its main indication is the removal of broad based adenomas and early rectal cancers. Further indications are palliative excisions of advanced cancers. From July 1983 till December 1990 the endoscopic system has been employed on 233 patients. The total sum of operations raised to 251 cases due to recurrences and new tumour formations. The overall crude 5 year survival with merely local removal of rectal cancer was 67% for early rectal carcinoma patients and 75% for patients with pT2 carcinomas. Early postoperative complications consisted of 5 intraperitoneal perforations, 4 recto-vaginal fistulas and 4 haemorrhages (complication rate 5.2%). There were 2 postoperative deaths due to cardiopulmonary failure (clinical lethality 0.8%). The overall recurrence rate of adenomas was 4.9%. In accordance with the selection criterias of other authors, our selection criteria for curative local excisions of rectal cancers enclose tumour diameter less than 4 cm, pT1 carcinomas, low grade malignancy and tumour free margins of locally excised specimen.
