Endometrial cancer is one of the most common gynecological malignancies worldwide. Surgical staging is the cornerstone of management and traditionally performed via laparotomy. However, minimally invasive surgery, particularly laparoscopy, has emerged as an effective alternative with potential benefits in reducing postoperative morbidity. This study aims to compare the outcomes of laparoscopic versus open (laparotomy) surgical staging in patients with endometrial cancer in low-resource settings. Primary aim: To compare early postoperative recovery after surgical staging for early-stage endometrial cancer between laparoscopic and open approaches, assessed primarily by time to ambulation. • Secondary aim: To compare intraoperative outcomes (operative time, blood loss, lymph node yield), postoperative morbidity (Clavien-Dindo classification), quality of recovery (QoR-15), length of hospital stay, same day discharge(SDD), discrepancy between preoperative curettage pathology and final histopathology, delay in initiation of adjuvant therapy, one-year disease-free survival, direct hospital costs between both approaches, and quality of life using EQ-5D-5L questionnaire. Given the limited resources and variations in surgical expertise in low-resource settings, this study seeks to evaluate the feasibility, safety, and effectiveness of laparoscopy compared to laparotomy. The findings may help guide clinical decision-making and optimize surgical approaches in similar healthcare environments.
Endometrial cancer is the most common gynecologic malignancy in developed countries, with increasing incidence related to obesity, aging, and metabolic disorders. Most patients present with early-stage disease confined to the uterus, making surgical staging the cornerstone of treatment. Standard management includes total hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymph node assessment when indicated for accurate staging and risk stratification . Minimally invasive surgery (MIS), particularly laparoscopy, has increasingly replaced laparotomy in the surgical staging of endometrial cancer because of its perioperative advantages. Previous studies demonstrated that laparoscopic surgery is associated with reduced blood loss, fewer postoperative complications, shorter hospital stay, and faster return to normal activity while maintaining comparable oncologic outcomes to open surgery. Recently, greater emphasis has been placed on patient-centered outcomes and enhanced recovery after surgery (ERAS) pathways. Early postoperative recovery is considered an important indicator of surgical quality and functional rehabilitation. Time to ambulation is a simple and clinically relevant marker of recovery, as delayed mobilization is associated with prolonged hospitalization and increased postoperative morbidity. Faster recovery may also facilitate earlier initiation of adjuvant therapy when indicated. Additionally, discrepancies between preoperative curettage pathology and final histopathology may alter risk stratification and postoperative management. Despite strong evidence supporting laparoscopy, most data originate from high-resource settings with advanced ERAS systems. Evidence from low-resource settings remains limited, particularly regarding functional recovery metrics, cost-effectiveness, and real-world delays in adjuvant therapy. Furthermore, few randomized trials have incorporated patient-reported recovery outcomes alongside oncologic endpoints.Therefore, this study aims to compare laparoscopic and open surgical staging for early-stage endometrial cancer regarding early postoperative recovery, perioperative outcomes, postoperative morbidity, delay in initiation of adjuvant therapy, and concordance between preoperative and final histopathological findings.

RECRUITINGEarly postoperative recovery assessed by time to ambulation (hours).
Time frame: From the end of surgery until the patient achieves independent ambulation or ambulation with minimal assistance, assessed during the first 24 postoperative hours.
Comparison of hospital stay duration between laparoscopic and open surgical staging
Time frame: From the day of surgery through hospital discharge, assessed up to 7 days postoperatively.
comparsion between same day discgarge between laparoscopic and open surgical staging
Time frame: Day 0 (day of surgery)
Pelvic lymph node yield (number of nodes)
Comparison of the total number of pelvic lymph nodes retrieved between laparoscopic and open surgical staging.
Time frame: At final histopathological examination (within 2 weeks postoperatively)
Short-Term Oncologic Outcomes
One-year disease-free survival (DFS), defined as the time from surgery to first documented recurrence (local, regional, or distant) or death from any cause.
Time frame: follow up for one year
Postoperative quality of recovery
Postoperative quality of recovery assessed by the Quality Of Recovery -15 questionnaire (QoR-15 questionnaire) 0-150 130-150: Excellent recovery 122-129: Good recovery 90-121: Moderate recovery \<90: Poor recovery / significant postoperative impairment
Time frame: at 12 hours, 24 hours, 48 hours postoperatively , and at time of hospital discharge (up to 5 postoperative days).
Comparison of estimated blood loss during surgery between laparoscopic and open surgical staging.
Time frame: During surgery (intraoperative period)
Comparison of intraoperative complications between laparoscopic and open surgical staging.
Time frame: During surgery
Postoperative complications (Clavien-Dindo classification, Grades I-V)
Comparison of the incidence and severity of postoperative complications between laparoscopic and open surgical staging. Complications will be graded according to the Clavien-Dindo classification, where Grade I represents minor deviation from normal postoperative course and Grade V represents death.
Time frame: Within 30 days after surgery
comparsion of health-related quality of life assessed using the EQ-5D-5L questionnaire between open and laparoscopic surgical staging
Time frame: baseline (preoperative), 6 weeks, and 12 weeks postoperatively.
hospital-based cost comparison between both surgical approaches
Hospital-based costs will include operating room time cost, surgical instruments and energy devices, hospital stay cost, and costs related to the management of postoperative complications occurring within 30 days after surgery.
Time frame: From surgery until hospital discharge, assessed up to 30 days postoperatively.
Discrepancy between preoperative curettage pathology and final histopathology
Comparison of histological type, tumor grade, and disease characteristics between preoperative endometrial sampling pathology and the final postoperative histopathological diagnosis.
Time frame: From preoperative endometrial sampling through final postoperative histopathological assessment, up to 30 days after surgery.
