Evaluation of Suzor forceps training by studying obstetric anal sphincter injuries: a retrospective study.

BACKGROUND: Instrumental deliveries are an unavoidable part of obstetric practice. Dedicated training is needed for each instrument. To identify when a trainee resident can be entrusted with instrumental deliveries by Suzor forceps by studying obstetric anal sphincter injuries. METHODS: A French retrospective observational study of obstetric anal sphincter injuries due to Suzor forceps deliveries performed by trainee residents was conducted from November 2008 to November 2016 at Limoges University Hospital. Perineal lesion risk factors were studied. Sequential use of a vacuum extractor and then forceps was also analyzed. RESULTS: Twenty-one residents performed 1530 instrumental deliveries, which included 1164 (76.1%) using forceps and 89 (5.8%) with sequential use of a vacuum extractor and then forceps. Third and fourth degree perineal tears were diagnosed in 82 patients (6.5%). Residents caused fewer obstetric anal sphincter injuries after 23.82 (+/- 0.8) deliveries by forceps (p = 0.0041), or after 2.36 (+/- 0.7) semesters of obstetrical experience (p = 0.0007). No obese patient (body mass index> 30) presented obstetric anal sphincter injuries (p = 0.0013). There were significantly fewer obstetric anal sphincter injuries after performance of episiotomy (p <  0.0001), and more lesions in the case of the occipito-sacral position (p = 0.028). Analysis of sequential instrumentation did not find any additional associated risk. CONCLUSION: Training in the use of Suzor forceps requires extended mentoring in order to reduce obstetric anal sphincter injuries. A stable level of competence was found after the execution of at least 24 forceps deliveries or after 3 semesters (18 months) of obstetrical experience.

Mortality rate of gestational trophoblastic neoplasia with a FIGO score of ≥13.

BACKGROUND: Gestational trophoblastic diseases include premalignant (partial and complete hydatidiform moles) and malignant entities referred to as gestational trophoblastic neoplasia. Use of the International Federation of Gynecology and Obstetrics prognostic score is encouraged in cases of gestational trophoblastic neoplasia to predict the potential for the development of resistance to single-agent chemotherapy. An International Federation of Gynecology and Obstetrics score of ≥7 defines a high-risk patient and requires combination chemotherapy. Appropriate and rapid diagnosis, treatment by specialized centers, and reduction of early deaths at the time of chemotherapy initiation have led to significant improvements in survival for patients with high-risk gestational trophoblastic neoplasia. There is a crucial need for the early identification of high-risk patients with gestational trophoblastic neoplasia who have an increased death risk to organize their treatment in highly specialized centers. OBJECTIVES: The purpose of this study was to describe cases of gestational trophoblastic neoplasia that have resulted in death, particularly in a subgroup with an International Federation of Gynecology and Obstetrics prognostic score of ≥13, for whom low-dose etoposide and cisplatin induction chemotherapy recently was shown to reduce early death rate. STUDY DESIGN: We identified 974 patients from the French Center for Trophoblastic Diseases who had a diagnosis of gestational trophoblastic neoplasia from November 1999 to March 2014. Among 140 patients who were at high risk of resistance to single-agent chemotherapy (International Federation of Gynecology and Obstetrics score, ≥7), 29 patients (21%) had a score of ≥13. Mortality rate was estimated with the use of the Kaplan-Meier method. RESULTS: The 5-year overall mortality rate, after the exclusion of placental site trophoblastic tumors and epithelioid trophoblastic tumors, was 2% for patients with gestational trophoblastic neoplasia (95% confidence interval, 1.25-3.13%). High-risk patients had a 5-year mortality rate of 12% (95% confidence interval, 7.49-18.9%). Patients with an International Federation of Gynecology and Obstetrics score of ≥13 had a higher 5-year mortality rate (38.4%; 95% confidence interval, 23.4-58.6%) and accounted for 52% of the deaths in the entire cohort. Early deaths, defined as those that occur within 4 weeks after treatment initiation, occurred in 8 patients of the entire cohort. Six of them had an International Federation of Gynecology and Obstetrics score of ≥13 at presentation, of whom 5 patients had brain and/or liver metastases. CONCLUSION: Gestational trophoblastic diseases with an International Federation of Gynecology and Obstetrics score of ≥13 have an increased risk of early death. We suggest that an International Federation of Gynecology and Obstetrics score of ≥13 becomes a consensual criterion for prediction of patients with gestational trophoblastic neoplasia with increased risk of death, particularly early death. These patients justify treatment in highly specialized gestational trophoblastic disease centers and may benefit from the use of induction low-dose etoposide and cisplatin.
