Endoscopic polypectomy for the removal of polyps of the small intestine.

Since intussusception is a common complication of the Peutz-Jeghers polyps, laparotomy should be recommended to remove them. However, all of them will not be palpable or discernible during laparotomy. Operative endoscopy was employed for removing polyps of the small intestine of a 22-year-old female who was previously diagnosed as Peutz-Jeghers syndrome. Using a newly designed enteroscope with two channels (SIF-2C, Olympus), four large polyps over 1 cm in size were removed from the ileum and jejunum with safety. Endoscopic polypectomy is one of the rapidly advancing fields and widely spread methods in gastrointestinal endoscopy since the introduction of electrosurgical techniques. Although the endoscopic removal of polyps arising from the esophagus, stomach, duodenum, colon and rectum can be performed with ease and safety, polypectomy for the polyps of the small intestine has never been performed because of the technical difficulties to handle the scope in the small intestine. Two channel enteroscope resolved this problem. Therefore, it is emphasized that double channel enteroscope makes the polypectomy in the small intestine possible and the indication of enteroscopy will be more extended.

[Surgical treatment of malignant polyps of the large intestine].

The report deals with the results of surgery in 1247 cases of colonic polyps. Malignant polyps were observed in 101 cases (8.1%). Eighty percent of polyps were up to 10 mm in size. Seventy five percent of malignant polyps were more than 10 mm in diameter. 94.4% of malignant polyps were in the rectum and sigmoid colon. Electro excision of malignant polyps via fibrocolonscope or rectoscope has been used on a large scale in recent years. Within five years after operation, newly-developed tumors were detected on the same sites in 11 cases (11.8%) (benign tumors--5, malignant polyps--4, carcinoma of large bowel--2). Newly-developed tumors were found at other sites in 26 patients (benign tumors--20, malignant polyps--5 and large bowel cancer--1).

[The characteristics of protein p53 expression in the mucosal epithelium of the large intestine affected by polyps and cancer].

The direct dependence between p53 expression in epithelial cells and the level of morphological malignant neoplasm was established as the result of investigation of expression of this biomolecular marker in 12 polyps and 35 colorectal cancer. It was shown that family cancer syndrome 1 type was observed in pedigrees of majority patients with p53 positive cancers.
