Case Report: Tubal recanalization and short-term re-pregnancy after repeat ligation following two cesarean sections.

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
Background: Tubal ligation is a widely used permanent female sterilization method. Laparoscopic tubal recanalization offers a pathway to restore natural fertility for women who desire pregnancy after sterilization. However, short-interval re-pregnancy following repeat tubal ligation after recanalization is clinically rare. Case presentation: We report a case of a 37-year-old woman, gravida 3, para 2, with a history of two previous cesarean sections, the second of which was accompanied by bilateral tubal ligation. Eight years after ligation, she underwent laparoscopic bilateral tubal recanalization due to remarriage and a renewed desire for childbearing. She conceived spontaneously 3 months postoperatively and delivered at 38 weeks via a third cesarean section, during which repeat bilateral tubal ligation was performed using the modified Pomeroy technique. Eleven months later, she conceived spontaneously again and underwent induced abortion due to no further fertility plans. Conclusion: Although pregnancy rates after tubal recanalization can reach 80%-90%, repeat ligation following recanalization does not guarantee absolute contraceptive efficacy. Spontaneous re-canalization with subsequent pregnancy remains possible. This case highlights the importance of standardized surgical technique, long-term follow-up, and postoperative contraceptive counseling, particularly in patients with a history of tubal surgery.
