Objective: To compare the quality of tissue from punch biopsy forceps (PB group) with round loop electrode (LE group) in colposcopically directed biopsy along with the evaluation of pain associated with each procedure.
Methods: Patients with abnormal cervical cytologic results and abnormal colposcopic findings were enrolled into a randomized trial into either a PB group or LE group. The quality of tissue was evaluated in regards to the size of tissue, site of tissue, and tissue damage. Each quality had 1 to 3 points and the sum of each quality contributed to the total tissue score that ranged from 3 to 9. Pain associated with each procedure was assessed by a visual analog scale (VAS). This was a clinical trial study and was registered at www.clinicaltrials.in.th (Identifier: TCTR20160404001).
Results: Ninety-six women who met all eligibility requirements were enrolled in the study. Forty-eight patients were randomly assigned to the PB group and 48 patients were randomized into the LE group. The characteristics of the patients were similar between the 2 groups with the exception of the median age. The median total tissue score was 8 points in the LE group which was more than the median of 7 points in the PB group with a statistically significant difference (p=0.014). However, the median VAS pain score in both groups was 3.4 (p=0.82).
Conclusion: The quality of cervical tissues obtained from biopsy with a round loop electrode was better than the punch biopsy forceps with no difference in the level of pain.
