Objective: To evaluate the use of endometrial cannula connected to a vacuum system for endocervical biopsy curette compared with Duncan and investigate factors. Method: Prospective, experimental, transversal and comparative study. It included a sample of 126 patients were seen at the Colposcopy and Cervical Pathology of Gynecology Maternity Concepción Palacios, between April 2011 and April 2012, they had an indication for biopsy endocervical. A history and clinical data related to pain perception through analog scale of 0 to 10. We assessed the quantity, quality of the sample and histopathology findings. Results: The main indications for endocervical biopsy for both groups were abnormal cytology with or without colposcopic abnormal findings (33 in group A and 26 in group B). Both groups showed a predominance of moderate pain patients (52.2 % and 67.7 %). There were 19 women (28.3 %) who reported severe pain, when we use Duncan curette biopsy and 3 patients (5.0 %) when endometrial cannula was used (P <0.005). In both groups, we obtain glandular epithelium lining and stroma (50.7.% y 49.1.%). The presence of predominantly hemorrhagic component was nil or low in both groups (P = 0.166). There was greater amount of material with the suction cannula (P = 0.001). Interpretation was considered insufficient for diagnosis or just was represented by endometrial tissue in 25.3 % in group A and 27.2 % in group B (P> 0.05). Conclusions: The biopsy taken with endometrial cannulas was more tolerated by patients, maintaining the same quality sample for diagnosis.
