The Pocket-Creation Procedure of Endoscopic Submucosal Dissection for Large Rectal Laterally Spreading Tumors
Published on: February 13, 2026
Abstract:
Within a ten year period we have performed 433 radical operations on the rectum. An anterior resection of rectum was done in 110 cases, low anterior resection in 60 patients, very low anterior resection was done by stapler in 32 patients and was sewn by hand in 10 patients. Colo-anal anastomoses were performed 86 times and abdominoperineal amputation of rectum sec. Miles 20 times. Local transsphincteric procedures were used 14 times. In 12 patients the colo-anal anastomosis was performed either for recurrence of tumor or after a Hartmann's procedure. In the carcinoma of the lower half of the rectum there is still an unsolved question: whether to perform a low or a very deep low anastomosis or whether an extirpation of rectum with sparing the sphincters and sewing a colo-anal anastomosis is more beneficial. In the years 1980-1995 we treated surgically 64 patients with a tumor in anal area. All patient underwent preoperative radio- and chemotherapy. In our group adenocarcinoma was demonstrated in 6 patients, squamous carcinoma in 48 patients and squamous cells of the carcinoma in situ in 10 patients.

Large Intestine
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
