Role of human papillomavirus testing and cytology in follow-up after conization.

OBJECTIVE: Adequate follow-up of women who have undergone conization for high-grade cervical lesions is crucial in cervical cancer screening programs. We evaluated the performance of testing for high-risk human papillomavirus (HPV) types, cytology alone, and combined testing in predicting cervical intraepithelial neoplasia grade 2 or worse (CIN2+) after conization. DESIGN: Prospective cohort study. SETTING: Denmark. POPULATION: 667 women attending for conization. METHODS: Cervical specimens were collected during 2002-2006 at first visit after conization for cytological examination and Hybrid Capture 2 detection of high-risk HPV. The women were passively followed until 2 years after first follow-up visit by linkage to the nationwide Pathology Data Bank. RESULTS: At first visit after conization (median time, 3.4 months), 20.4% were HPV-positive and 17.2% had atypical squamous intraepithelial lesions or more severe cytology (ASCUS+). The 2-year incidence of CIN2+ after conization was 3.6%. Sensitivity for detection of CIN2+ after conization was 81.0% [95% confidence interval (CI) 58.1-94.6] for positive cytology (ASCUS+ threshold) and 95.2% (95% CI 76.2-99.9) for HPV testing and for combined testing. Specificity of ASCUS+ cytology (85.2%; 95% CI 82.0-88.0) was higher than that of HPV testing (82.4%; 95% CI 79.0-85.4) and markedly higher than that of combined testing (73.2%; 95% CI 69.3-76.8). The margin status had no significant added value. CONCLUSIONS: Testing for high-risk HPV three to four months after conization is more sensitive than ASCUS+ cytology for identifying women at risk for relapse of CIN2+ within 2 years. Further studies are needed to evaluate whether HPV testing could be a stand-alone test in follow up after conization.

Effect of systematic local infiltration analgesia on postoperative pain in vaginal hysterectomy: a randomized, placebo-controlled trial.

OBJECTIVE: To assess the effect of systematic local infiltration analgesia on postoperative pain in vaginal hysterectomy, and describe the technique in detail. DESIGN: A randomized, double-blind, placebo-controlled study following the CONSORT criteria. SETTING: A university hospital. PATIENTS: Thirty-seven patients undergoing vaginal hysterectomy. METHODS: Patients received high-volume (50 mL) ropivacaine 0.50% (n = 20) or saline (n = 17) infiltration using a systematic technique ensuring uniform delivery to all tissues incised, handled or instrumented during the procedure. MAIN OUTCOME MEASURES: Pain, nausea, vomiting and opioid requirements were assessed for 32 h as well as time spent in the post-anesthesia care unit and time to first mobilization. RESULTS: Pain at rest was significantly reduced after one, four and eight hours in the ropivacaine group (p ≤ 0.001-0.01). Pain during coughing was significantly reduced after one and four hours (p ≤ 0.001 and p ≤ 0.003), and pain during movement was significantly reduced after four hours (p ≤ 0.02). Opioid requirements and time spent in the post-anesthesia care unit were significantly reduced in the ropivacaine group (p < 0.001 and p < 0.001, respectively), as well as the time to first mobilization (p < 0.001). CONCLUSION: Intra-operative systematic local infiltration analgesia reduces postoperative pain in patients undergoing vaginal hysterectomy, facilities mobilization and improves early recovery.
