Mo1625 OVERUTILIZATION OF SURGICAL RESECTION FOR BENIGN COLORECTAL POLYPS: ANALYSIS FROM A TERTIARY CARE CENTER

Abstract Background and study aims Adequate removal of precancerous polyps is an independent factor in colorectal cancer prevention. Despite advances in polypectomy techniques, there is an increasing rate of surgery for benign polyps. We assessed whether surgical resection is properly utilized for benign colorectal polyps. Patients and methods We identified 144 patients with surgical resection for benign colorectal polyps. Polyp location, size and the indication for and type of surgery were obtained. For the purposes of this analysis, we assumed that gastroenterologists should assess polyp size accurately, endoscopically resect polyps < 2 cm, and treat incompletely excised polyps on follow-up. Results A total of 118 patients (82 %) were referred to surgery without attempted endoscopic removal. In 26 (22 %) of 118, the macroscopic polyp size was < 2 cm (23 in right, 3 in the left colon) and 18 (15 %; 14 in the right, four in the left colon) were found to have had size overestimation during endoscopy. Twenty-two (15 %) of 144 underwent surgical resection for incomplete endoscopic resection of adenomas (16 in the right, 6 in the left colon); 12 (54.5 %) had a residual polyp size of < 2 cm (10 in the right colon; 2 in the left colon). In-hospital mortality was 0.7 % and morbidity was 20.1 %. Conclusions Of the patients, 41 % could have potentially avoided surgical intervention (37 polyps < 2 cm and/or size overestimations precluding endoscopic polypectomy and 22 incomplete resections). When including polyps with size ≥ 2 to < 4 cm, the percentage of patients with avoidable surgery reached 80 %. This confirms the need to develop standardized quality metrics for endoscopic polypectomies and for better overall training of endoscopists performing these procedures. Given the risks of surgery, referral to an experienced gastroenterologist should be considered as a first step.

ABSTRACT BACKGROUND: There is limited data from Saudi Arabia on the demographic characteristics, outcomes and effectiveness of different treatment modalities in children with intracranial ependymoma. OBJECTIVE: Study the characteristics of pediatric ependymoma and outcomes of treatment modalities in Saudi Arabia. DESIGN: Retrospective. SETTING: Tertiary care center. PATIENTS AND METHODS: Children with intracranial ependymoma who were younger than 14 years of age and treated between 2006 and 2015 were included in the study. Patients with prior radiation, chemo-therapy, or surgical resection at other centers were excluded. MAIN OUTCOME MEASURES: Kaplan-Meier survival curves were used to estimate the event-free (EFS) and overall survival (OS) rates of the patients. SAMPLE SIZE: 22. RESULTS: Of the 22 children, 4 (18.2%) were less than three years old. All intracranial ependymomas had upfront surgical resection of the primary tumor. Gross total resection was achievable in 9 (42.9%) cases and subtotal resection in another 9 (42.9%). Near-total resection was done in 3 (14.3%) cases. Median time from surgery to start of radiotherapy was 62 days. RT was given to 17 (77.3%) patients. Both mean and median RT dose was 55.8 Gy. Only 5 (22.7%) of the children received chemotherapy. The median duration of follow-up was 5.38 years and the median time for EFS was 2.27 years. The cumulative OS rate of the study was 44.5%. The cumulative EFS survival rate of the study was 18.6%. Among demographic, pathological, radiological features, none had a statistically significant effect on the survival. CONCLUSIONS: The outcomes are comparable to those reported by international investigators for similar populations. Further improvements can be achieved by avoiding delays in radiation therapy and adding molecular staging. LIMITATIONS: The limited number of cases, retrospective nature, lack of molecular biology and size of the tumors. CONFLICT OF INTEREST: None.
