Aim: Loop electrosurgical excisional procedure (LEEP) is a major treatment method for cervical precancerous lesions. However, recurrence rates were estimated to be 15%, and the risk is increased if a surgical margin is involved by dysplastic cells. This study aimed to identify the risk factors for recurrence of cervical precancerous lesions in patients with positive margins. Methods: We retrospectively reviewed medical records of patients who underwent LEEP between 2012 and 2014 and had a positive surgical margin. Clinicopathologic factors were collected, including age, parity, menopausal status, smoking, human papilloma virus infection, results of cytology/biopsy/LEEP, and specimen size and volume. Results: A total of 117 patients with positive margins were included, and 26 (22.2%) patients had recurrence. According to a multivariate analysis, the recurrence rates were significantly higher in parous women (adjusted hazard ratio [HR], 2.92; 95% confidence interval [CI], 1.00–8.49), but positive margins at the exocervix (adjusted HR, 0.39; 95% CI, 0.17–0.91) and volume ≥4000 mm3 (adjusted HR, 0.36; 95% CI, 0.16–0.82) showed negative correlation. Conclusions: The risk of recurrence for cervical precancerous lesions increased in patients with a history of previous delivery, positive margin at the endocervix, and specimen volume of LEEP <4000 mm3. These results could help gynecologists determine optimal treatment options for patients with positive margins. [ABSTRACT FROM AUTHOR]

Background: The fluoroscopic-guided epidural access is occasionally challenging; therefore, the contralateral oblique (CLO) view has emerged as an alternative approach. The CLO view appears to be optimal for mid-thoracic epidural access; however, evidence on its utility is lacking. Therefore, we aimed to evaluate the clinical usefulness of the CLO view at 60°±5° compared with the lateral (LAT) view using fluoroscopic-guided mid-thoracic epidural access.Methods: Patients were randomly allocated to undergo mid-thoracic epidural access under the fluoroscopic LAT view (LAT group) or CLO view (CLO group). The primary outcome was the first-pass success rate of mid-thoracic epidural access. The secondary outcomes were procedural pain intensity, patient satisfaction, needling time, number of needle passes, and radiation dose.Results: Seventy-nine patients were included. The first-pass success rate was significantly higher in the CLO group than in the LAT group (68.3% vs 34.2%, difference: 34.1%; 95% CI 13.3 to 54.8; p=0.003). Procedural pain intensity was significantly lower in the CLO group than in the LAT group. Patient satisfaction was significantly greater in the CLO group than in the LAT group. The needling time and the number of needle passes were significantly lower in the CLO group than in the LAT group. Radiation dose in the CLO group was significantly reduced compared with that in the LAT group.Conclusions: The fluoroscopic CLO view at 60°±5° increased the success rate and patient satisfaction and reduced the procedural time and patient discomfort compared with the LAT view when performing mid-thoracic epidural access. Therefore, the CLO view at 60°±5° can be considered for mid-thoracic epidural access under fluoroscopic guidance.Trial Registration Number: KCT0004926. [ABSTRACT FROM AUTHOR]

Background: Cervical epidural steroid injection is associated with rare but potentially catastrophic complications. The contralateral oblique (CLO) view may be a safe and feasible alternative to the lateral (LAT) view for fluoroscopic-guided cervical epidural steroid injection. However, evidence for the clinical usefulness of the CLO view for cervical epidural steroid injection is lacking. We assessed the clinical usefulness of the CLO view for cervical epidural steroid injection in managing cervical herniated intervertebral discs.Methods: Patients were randomly assigned to receive fluoroscopic-guided cervical epidural steroid injection under LAT view or CLO view at 50±5° degrees groups. The primary outcome was the needling time comparison between the two groups. Secondary outcomes were comparison of first-attempt success rate, needle tip visualization and location, total number of needle passes, final success rate, crossover success rate and false-positive/negative loss of resistance. Complications and radiation dose were also compared.Results: The needling time significantly decreased in the CLO than in the LAT group. The first-attempt success rate was significantly higher in the CLO compared with the LAT group. The needle tip was clearly visualized (p<0.001) and located more often on (or just anterior to) the ventral interlaminar line (p<0.001) in the CLO than in the LAT group. There were significantly fewer needle passes (p=0.019) in the CLO than in the LAT group. There were no significant differences in the final success, crossover success, false-positive/negative loss of resistance or radiation dose between the groups. Two (5.9%) cases in the LAT group experienced complications.Conclusion: The CLO view may be recommended for fluoroscopic-guided cervical epidural steroid injection, considering its better clinical usefulness over the LAT view.
