Laparoscopic Radical Prostatectomy: Assessing the Impact of Residency Training on Early Surgical Experience

Abstract

Background: Transferring the intricate laparoscopic radical prostatectomy (LRP) technique poses a considerable challenge for novice surgeons. Fellowship programs, typically lasting three to twelve months, remain the primary avenue for acquiring laparoscopic skills. This study proposes that residency-based laparoscopy training confers distinct advantages over fellowship programs during the initial stages of LRP. Methods: The study analyzed retrospectively collected data and operation videos from the first and second sets of fifty operations (Group 1 and Group 2) out of a total of 553 performed by the "fellow" surgeon between August 2009 and December 2022, and the first fifty operations by the "resident" surgeon from January 2022 to June 2023. Parameters examined included patient demographics, preoperative prostate-specific antigen (PSA) levels, grades, stages, operation durations, complications, postoperative outcomes, and short-term (6-month) oncological and functional results. Results: No statistically significant differences were observed in prostate volume, age, body mass index, or PSA levels between Groups 2 and 3 or 1 and 3 (p > 0.05). Nevertheless, Group 3 exhibited significantly more International Society of Urological Pathology grade 3 and 4 cases than Group 1 (p = 0.004) and Group 2 (p = 0.006). Additionally, Group 3 had a shorter anastomosis time (AT) (25 min vs. 35 min, p < 0.001) and reduced estimated blood loss (EBL) (275 mL vs. 385 mL, p = 0.008) compared to Group 1. No significant differences were found among the groups regarding intraoperative complications, nerve sparing, or lymph node dissection rates. While Group 2's anastomosis time was comparable to that of Group 3 (24 min vs. 25 min, p = 0.144), it demonstrated a significantly shorter insufflation duration (150 min vs. 170 min, p < 0.001). Functional outcomes, including continence and erectile function at six months, showed no significant differences across the groups. Conclusions: This study underscores the potential benefits of integrating LRP training into a surgeon's residency, particularly in the early stages of their learning curve (LC), by reducing anastomosis and operation times and EBL in the first fifty cases. Initial findings suggest that implementing modular training in residency programs could enhance LRP proficiency, benefiting both surgeons and patients.
