Objective:
To study the clinical and endoscopic features of chronic hemorrhagic proctitis by radiotherapy in the National Institute of Neoplastic Diseases of Peru.
Materials And Methods:
The study was descriptive, retrospective and longitudinal, with a population of 588 patients with this pathology, in the period 2011-2013, from which 114 patients were selected by randomized probabilistic sampling. Descriptive and inferential statistics were used for the analysis of qualitative and quantitative variables.
Results:
The main results were a latency period of 439.96 days; the severity of clinical rectal bleeding was grade 2 and 3 in 86.84%, the mean hemoglobin in chronic hemorrhagic proctitis by radiotherapy was 11.63 g / dl, the endoscopic findings were moderate severity in 58.77%, extension rectal only in 92.11%, slight friability of 43.86%, compromise less than 33% of the rectal surface in 71.93% and an average length of 7.28 cm. The inflammatory findings were 0.88% scars, erosions of 0.88%, ulcers of 7%, fistula of 0.88% and 3.51% of rectal stenosis, single or combined argon plasma coagulation (APC) treatment was offered in 96% of cases.
Conclusion:
Chronic hemorrhagic proctitis is an important complication of pelvic radiotherapy, with characteristic clinical and endoscopic findings.
