[Polyposis of the stomach. Endoscopic treatment or follow-up?]
Abstract:
Out of 3243 patients with gastric polips, polyposis was diagnosed in 298 ones including 135 cases of complicated and 163 cases of uncomplicated forms. Hyperplastic polips were diagnosed in 281 patients. Along with hyperplastic polyps, solitary adenomas were diagnosed in 9 cases, Peitz-Jegerc polyps - in 6, and juvenile polyps - in 2. Polypectomy was performed in 153 patients: partial - in 104, and total - in 49. Follow-up was carried out in 98 non-operated patients, indications for endoscopic surgery were seen in 18 cases. After partial endoscopic polypectomy, repolypectomy was performed in 24 cases: single - in 8, multiple - in 16. Repeated endoscopic treatment after total polypectomy was performed in 3 patients. There were no cases of polyp transformation into cancer. Open surgical treatment was not performed. There were no severe complications after endoscopic treatment.
