Clinical impact of surgical energy device (Caiman®) IN elderly patients with Endometrial Cancer (protocol ID: Cineca)

Study objective: To investigate the clinical performance of the Caiman® energy device in class A radical laparoscopic hysterectomy (RLH) according to Querleu-Morrow classification, combined with bilateral salpingo-oophorectomy (BSO) and pelvic lymph node assessment in elderly patients with early-stage endometrial cancer (EC), specifically focusing on hemostatic effectiveness and safety. Design: Single-institution, prospective observational study. Setting: Gynecologic Oncology Unit, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy. Patients: Forty-three women over 65 years with FIGO stage IA or IB endometrioid EC were enrolled from September 2021 to August 2023. Interventions: Use of Caiman® energy device in RLH combined with BSO and pelvic lymph node assessment in elderly patients. Measurements: The primary endpoint was operative time, with secondary endpoints including perioperative outcomes and postoperative complications. Main results: Results demonstrated a median surgical time of 135 min, with no significant intraoperative complications attributed to the Caiman® device. Postoperative complications were minimal, with no severe complications (Grade 4 or 5) and a median hospital stay of two days. Conclusion: The study highlights the advantages of the Caiman® in enhancing surgical efficiency while minimizing risks for elderly patients, suggesting its potential for improving resource allocation and patient outcomes in oncologic surgery. The findings of this study suggest the feasibility of using the Caiman® device for surgical procedures in elderly patients with early-stage endometrial cancer. Future prospective randomized trials are needed to establish its efficacy compared to traditional surgical methods.
