The first case of laparoscopic surgery for cecal cancer occurring in a blind loop.

ABSTRACT

Cancer occurrence in a blind loop is extremely rare. An 86-year-old Japanese woman underwent colonoscopy for tarry stools and weight loss; it revealed a bypass of the transverse colon and small intestine, cecal cancer, and a polyp. She had suffered from acute appendicitis and had undergone two surgeries at age 25 an appendectomy and then a bypass surgery between the transverse colon and the small intestine. We performed a laparoscopy-assisted ileocecal resection for the cancer and polyp in the blind loop with an end-to-side instrumental anastomosis. The pathological examination demonstrated that the cancer was medullary carcinoma (T2, N0, M0, Stage I) and the polyp was tubular adenoma. Two months have passed since the patient's discharge, and she is free of abdominal complaints. Our literature search identified 10 cases of cancer in a blind loop. Laparoscopy-assisted surgery may be possible in patients who have undergone blind-loop surgery.
