AbstractTubal pregnancy is a common cause of maternal mortality in early pregnancy. Transumbilical laparoendoscopic single-site surgery (TU-LESS) has gained popularity due to its safety and aesthetic advantages. However, the lack of affordable disposable entry platforms hinders its widespread adoption. This study aimed to investigate the learning curve of tubal pregnancy removal using single-incision multiport (SIMP) laparoscopy and provide guidance for novice gynecologists. A retrospective analysis was conducted on cases of ectopic pregnancy (EP) diagnosed at Dongguan Songshan Lake Central Hospital from June 2020 to June 2022. The analysis included 50 cases, with 25 undergoing single-port laparoscopy and 25 undergoing conventional laparoscopy (CL). Various indicators, including body mass index (BMI), previous pregnancies, mass size, hemoglobin levels, surgical duration, and complications, were collected. Learning curve analysis using the cumulative sum (CUSUM) technique was performed to assess procedural proficiency. There were no significant differences in patient characteristics or complications between the 2 groups. However, the single-port laparoscopy group exhibited a statistically significant longer average surgical time (41.60 ± 13.38 minutes) compared to the conventional laparotomy group (32.96 ± 7.32 minutes). The CUSUM analysis demonstrated a decline in surgical time after the completion of approximately 11 cases, indicating an improvement in SIMP laparoscopy surgical proficiency. SIMP laparoscopy for tubal pregnancy removal achieved similar safety outcomes as CL. Notably, the CUSUM analysis revealed that proficiency in single-port laparoscopy could be achieved after approximately 11 cases, leading to stable surgical times. These findings serve as valuable guidance for novice gynecologists interested in adopting single-incision laparoscopy.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
