Assessment of postoperative uterine isthmus thickness on MRI after surgical resection of retrocervical deep infiltrating endometriosis.
Observational study in Abdominal radiology (New York), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
STUDY
objectiveThe aim of this study was to assess the impact of endometriosis surgery in the retrocervical area and/or USL on the thickness of the posterior uterine isthmus, and subsequently the potential risk of posterior uterine rupture during labor.
designRetrospective observational study.
settingImproving the management of patients with deep infiltrating endometriosis, keeping in mind potential obstetric consequences. PATIENTS: All endometriosis patients treated surgically at the Croix-Rousse University Hospital during the study period for the resection of a lesion on one or both USL and/or in the retrocervical region were included if preoperative and postoperative MRI images were available in their medical record.
interventionsEvaluating the variation of posterior uterine isthmus thickness on MRI images after retrocervical surgery for deep infiltrating endometriosis. Searching for predictive markers of posterior uterine isthmus thinning. MEASUREMENTS AND MEAN
resultsForty-two patients were included between 2016 and 2020. We observed a significant decrease in the sagittal thickness of the median posterior uterine isthmus after surgery (-2.25 mm, 95% CI -3.18 to -1.32, p<.01). A significant association was also found between the thinning of the median posterior uterine isthmus on the sagittal section and preoperative urinary symptoms (p =.04), a history of digestive resection with ileostomy (p =.02) and the presence of post-voiding residue ≥ 100 cc postoperatively (p<.01). We observed 6 pregnancies in 4 patients (9.5%). Four pregnancies were carried to term with cesarean delivery.
conclusionThe resection of retrocervical endometriosis is associated with postoperative thinning of the posterior uterine isthmus, which seems positively associated with the complexity of the rest of the surgery.
