RESUMO

OBJECTIVES: Surveillance colonoscopy is recommended after polypectomy because adenoma recurrence is common. The aim of this study was to evaluate the predictors of high-risk adenoma occurrence at surveillance colonoscopy in patients who undergo colorectal adenoma removal and to clarify the association between age and recurrent colorectal adenoma. METHODS: This retrospective study included 563 patients who had colorectal adenomas at baseline colonoscopy and who underwent surveillance colonoscopy. The risk factors for recurrent adenoma were evaluated and the 5-year cumulative incidence rates of overall and high-risk adenoma were compared according to age group. RESULTS: During a mean follow-up period of 3.1 years, 305 (54.2%) patients had overall adenoma recurrence, and 80 (14.2%) patients had high-risk adenoma at surveillance colonoscopy. In a multivariate analysis, old age (≥60 years) and presence of multiple adenomas (3 or more) were significantly associated with high-risk adenoma (p = 0.002 and p = 0.006 respectively). The 5-year cumulative incidence rates of high-risk adenoma were 7.4, 16.7, and 24.1% in the < 50, 50-59, and ≥60 years group respectively (p < 0.001). CONCLUSIONS: Old age (≥60 years) and presence of multiple adenomas (3 or more) were strongly associated with the occurrence of high-risk adenoma at surveillance colonoscopy. The 5-year cumulative incidence of high-grade adenoma was significantly high in the old age group.

RESUMO

Intussusception is a common in pediatric age group. But it is rare in adults. And intussusception caused by tumor account for 1% of bowel obstructions in adult. Intussusception is an extremely rare cause of abdominal pain in pregnancy. In particular, cases of Intussusception due to colorectal cancer during pregnancy have never been reported in Korea. Our patient is a 34 years old woman who presented at 14 weeks of her second pregnancy. She presented with right lower abdominal discomfort and intermittent palpable mass which was usually spontaneously resolved. In the MRI study, pathologic asymmetric wall thickening was still noted and ileocolic intussusception was noted, and in colonoscopy, there was ulcerofungating mass around ileocecal valve which may be a leading point of intussusception. Biopsy was done. Pathologic finding was poorly differentiated adenocarcinoma. Under the patient agreement, we performed dilatation and curettage and laparoscopic right hemicolectomy and lymph node dissection. Now she is receiving a FOLFOX chemotherapy.
