To evaluate the efficacy of postpartum tubal sterilization training program with minilaparotomy approach (PTSMA).
From September 2020 to November 2021, 24 first-year Obstetrics and Gynecology (Ob/Gyn) residents were randomly allocated into 2 groups of traditional apprenticeship learning (watching video clip) versus apprenticeship learning plus PTSMA attending. The program consisted of didactics followed by self-practicing with 2 stations of postpartum tubal sterilization simulators (PTSS). All participants were allowed to perform their first tubal sterilization under supervision within a few days after training. Their surgical skills were blindly evaluated by 2 experts through the recorded videos. Five domains of direct observation of procedural skills (DOPS) score introduced by Royal Thai College of Obstetricians and Gynecologists were assessed. DOPS score, operative time, blood loss and post-op complication were analyzed and compared.
Median of total DOPS score in the PTSMA group was higher than the non-PTSMA group (93 vs. 73, p = 0.020). Concerning 2 domains of DOPS score (tubal fishing and tubal sterilization), the PTSMA group had the higher median score than the non-PTSMA group (36 vs. 24, p = 0.045 and 40 vs. 32, p = 0.020). There was no significant difference observed in the median score of 3 other domains (peritoneal cavity accessing, abdominal wall closure and complication prevention), estimated blood loss and operative time.
Postpartum tubal sterilization training program with minilaparotomy approach using instructive simulators significantly improved the total DOPS score especially tubal fishing and tubal ligation skills in Ob/Gyn residents.
The study evidently showed the benefit of PTSMA with an inexpensive and simple to prepare models. In unexperienced operators, practicing in model prior to surgery should be encouraged to improve their operative skills.
