Introduction: Colorectal carcinoma (CCR) is worldwide the third most frequent cancer in men and the second in women. There is controversy deciding when endoscopic treatment is curative for CCR in early stage and when surgical resection should be performed. Objectives: The objective is to describe the recurrence rate of superficial colorectal carcinoma on pediculate or sessile polyp in patients treated by endoscopic resection. In addition, as secondary objectives, the endoscopic and anatomopathological factors of the polyps and the complications of the technique will be described. Material and Methods: Unicentric Prospective Descriptive Observational Study that includes all colonoscopies carried out in the official CCR screening program of the VII-Murcia Este Health area, with carcinoma finding on adenomatous polyp (PT1), stratified according to the Haggitt classification of Haggitt of 0 to 4, from January 2021 to the estimated sample size. Results of the pilot study: A sample of 27 patients with an average age of 64 years and a male predominance (55.6%) are obtained. Polyps were mostly in Sigma (63%) and most of them were paris pediculated polyps (63%). Regarding the microscopic classification according to Haggitt classification, 27% were Haggitt 0, followed by 22.2% Haggitt 3, 18.5% Haggitt 2, 14.8% Haggitt 1, and finally, 7 , 4% Haggitt 4. presented an average of 26 mm in size, the majority being moderately differentiated (59.3%). Only 7.4% had vascular and lymphatic infiltration and 3.7% had a distance of 1 mm on the edge of the piece. As complications of polypectomy, rectorrhagia was observed in a patient. Four patients received surgical treatment. After 3-6 months, no tumor recurrence was observed in any of the patients.
Conclusions: No tumor recurrence has been observed after 3-6 months of endoscopic resection in any case. Surgical treatment has been chosen in those patients who presented bad prognosis factors, such as Haggitt 4, poorly differentiated CCR, distance from resection less than 1 mm, presence of Budding and presence of lymphatic and vascular affectation.
