Hysteroscopic removal of retained products of conception following first trimester medical abortion.

ABSTRACT: Study ObjectiveTo investigate the use of operative hysteroscopy instead of traditional curettage in women with retained products of conception (RPOC) following first trimester medical abortion, with the aim of reducing post-operative intrauterine adhesions.DesignRetrospective study.SettingGynecology department in a University affiliated hospital.PatientsAll women treated by hysteroscopy for RPOC following first trimester medical abortion using the mifepristone-misoprostol protocol for pregnancy termination or the misoprostol protocol for early missed abortion from January 2013 to August 2016.InterventionOperative hysteroscopy for removal of RPOC. Post-operative intrauterine adhesions were assessed by diagnostic office hysteroscopy after 6-8 weeks.Measurements and Main Results50 cases were identified. The mean time from medication administration to the operative hysteroscopy was 1.7 ± 0.7 months. Operative hysteroscopy with blunt use of the resectoscopic loop was used to remove all specimens, and all procedures were completed without intra-operative complications. Two patients (4.0%) were readmitted for fever. Pathology confirmed the presence of RPOC in 45 (90.0%) cases. On follow-up office hysteroscopy, a normal uterine cavity without evidence of intrauterine adhesions was seen in 29/29 (100%) women.ConclusionHysteroscopy for removal of RPOC following medical abortion is associated with low rates of complications and post-operative intrauterine adhesions.

Project description:IntroductionNumerous studies have been performed assessing optimal treatment regimens for evacuating (retained) products of conception from the uterus, but standardized criteria for diagnosing retained products of conception (RPOC) are still lacking. We aim to provide an overview of diagnostic criteria in current literature, used to diagnose RPOC after induced first-trimester abortion or early pregnancy loss.Material and methodsPubmed, EMBASE, and the Cochrane library were searched systematically up until March 2020 for English articles reporting on induced abortion or early pregnancy loss. Articles not specifying diagnostic criteria used to assess completeness of treatment were excluded, as were conference abstracts, expert opinions, reviews, and case reports. Four elements of diagnostic criteria were described: diagnostic tools, parameters used within these tools, applied cut-off values, and timing of follow up. Additionally, a meta-analysis was performed assessing diagnostic qualities of the most often applied diagnostic tool and parameter.ResultsThe search strategy yielded 1233 unique articles, of which 248 were included, with a total of 339 517 participants. In the 79 included randomized controlled trials, six diagnostic tools to assess RPOC were identified, combined in 14 ways, with 55 different cut-off values. In 169 observational studies, seven diagnostic tools were identified, used in 28 combinations, applying 89 different cut-off values. Transvaginal ultrasonographic measurement of endometrial thickness with a cut-off value of at least 15 mm indicating RPOC, was used most frequently. In the timing of follow-up there was great variation, with 55 and 107 different combinations in randomized controlled trials and observational studies, respectively. Assessment of treatment success was scheduled most often around 2 weeks after treatment. Diagnostic qualities of endometrial thickness of 15 mm or more was not adequately assessed.ConclusionsThere is wide variation in the way RPOC are assessed, and the criteria used to define RPOC following induced abortion and early pregnancy loss; ultrasonographic measurement of endometrial thickness, with a cut-off of 15 mm or more 2 weeks after primary treatment is the most widely used diagnostic approach. A meta-analysis on diagnostic accuracy of endometrial thickness of 15 mm or more did not lead to solid results. These findings can be a first step to develop a workable standard of establishing RPOC after induced abortion or early pregnancy loss.

Project description:BackgroundTraditionally the gold-standard technique for the treatment of spontaneous abortion has been uterine evacuation by aspiration curettage. However, many studies have proposed medical treatment with misoprostol as an alternative to the conventional surgical treatment. The aim of this study was to apply cost minimization methods to compare the cost and effectiveness of the use of vaginal misoprostol as a medical treatment for first trimester spontaneous abortion with those of evacuation curettage as a surgical treatment.Methodology/principal findingsWe present a longitudinal, prospective and quasi-experimental research study including a total of 547 patients diagnosed with first-trimester spontaneous abortion, in the period from January 2013 to December 2015. Patients were offered medical treatment with 800 mg vaginal misoprostol or evacuation curettage. Patients treated with misoprostol were followed-up at 7 days and a transvaginal ultrasound was performed to confirm the success of the treatment. If it failed, a second dose of 800 mg of vaginal misoprostol was prescribed and a new control ultrasound was performed. In case of failure of medical treatment after the second dose of misoprostol, evacuation curettage was indicated. The effectiveness of each of the treatment options was calculated using a decision tree. The cost minimization study was carried out by weighting each cost according to the effectiveness of each branch of the treatment. Of the 547 patients who participated in the study, 348 (64%) chose medical treatment and 199 (36%) chose surgical treatment. The overall effectiveness of medical treatment was 81% (283/348) and surgical treatment of 100%. The estimated final cost for medical treatment was € 461.92 compared to € 2038.72 for surgical treatment, which represents an estimated average saving per patient of € 1576.8.Conclusions/significanceMedical treatment with misoprostol is a cheaper alternative to surgery: in the Spanish Public Healthcare System, it is five times more inexpensive than curettage. Given its success rates higher than 80%, mild side effects, controllable with additional medication and the high degree of overall satisfaction, it should be prioritized over the evacuation curettage in patients who meet the treatment criteria.

Project description:BackgroundRetained products of conception (RPOC) often cause severe postpartum hemorrhage (PPH) but the clinical significance of RPOC in placenta previa is unclear. This study aimed to investigate the clinical significance of RPOC in women with placenta previa. The primary outcome was to evaluate risk factors of RPOC and the secondary outcome was to consider risk factors of severe PPH.MethodsSingleton pregnant women with placenta previa who underwent cesarean section (CS) and placenta removal during the operation at the National Defense Medical College Hospital between January 2004 and December 2021 were identified. A retrospective analysis was performed to examine the frequency and risk factors of RPOC and the association of RPOC with severe PPH in pregnant women with placenta previa.ResultsThis study included 335 pregnant women. Among these, 24 (7.2%) pregnant women developed RPOC. Pregnant women with prior CS (Odds Ratio (OR) 5.98; 95% Confidence Interval (CI) 2.35-15.20, p < 0.01), major previa (OR 3.15; 95% CI 1.19-8.32, p < 0.01), and placenta accreta spectrum (PAS) (OR 92.7; 95% CI 18.39-467.22, p < 0.01) were more frequent in the RPOC group. Multivariate analysis revealed that prior CS (OR 10.70; 95% CI 3.47-33.00, p < 0.01,) and PAS (OR 140.32; 95% CI 23.84-825.79, p < 0.01) were risk factors for RPOC. In pregnant women who have placenta previa with RPOC or without RPOC, the ratio of severe PPH were 58.3% and 4.5%, respectively (p < 0.01). Furthermore, the occurrence of prior CS (OR 9.23; 95% CI 4.02-21.20, p < 0.01), major previa (OR 11.35; 95% CI 3.35-38.38, p < 0.01), placenta at the anterior wall (OR 3.44; 95% CI 1.40-8.44, p = 0.01), PAS (OR 16.47; 95% CI 4.66-58.26, p < 0.01), and RPOC (OR 29.70; 95% CI 11.23-78.55, p < 0.01) was more in pregnant women with severe PPH. In the multivariate analysis for severe PPH, prior CS (OR 4.71; 95% CI 1.29-17.13, p = 0.02), major previa (OR 7.50; 95% CI 1.98-28.43, p < 0.01), and RPOC (OR 13.26; 95% CI 3.61-48.63, p < 0.01) were identified as risk factors.ConclusionsPrior CS and PAS were identified as risk factors for RPOC in placenta previa and RPOC is closely associated with severe PPH. Therefore, a new strategy for RPOC in placenta previa is needed.
