Therapeutic value of endoscopic submucosal dissection in the elderly with early colorectal cancer and precancerous lesion / 中华消化内镜杂志

ABSTRACT

Clinical data of 210 patients with early colorectal cancer and precancerous lesion treated by endoscopic submucosal dissection (ESD) in the Digestive Endoscopy Center of the Seventh Medical Center of Chinese PLA General Hospital from January 2015 to March 2018 were collected and analyzed retrospectively. Patients were divided into two groups according to the age: the elderly group (≥65 years old, 100 cases) and the non-elderly group (<65 years old, 110 cases). The en bloc resection rate, complete resection rate,and curative resection rate of the elderly group were 92.0% (92/100), 91.0% (91/100) and 89.0% (89/100), respectively. The above indicators of the non-elderly group were 90.9% (100/110) ( P=0.972), 90.0% (99/110) ( P=0.991) and 88.2% (97/110) ( P=1.000), respectively. The incidence of intraoperative perforation in the elderly group was 4.0% (4/100) and in the non-elderly group was 6.4% (7/110) ( P=0.543). Delayed postoperative bleeding rate was 2.0% (2/100) in the elderly group, and 0 (0/110) in the non-elderly group ( P=0.226). ESD is effective and safe in treating early colorectal cancer and precancerous lesion in elderly patients.
