Objective: The purpose of this study was to evaluate the feasibility of sentinel lymph node (SLN) detection in endometrial cancer patients with hysteroscopic injection of tracers. Study design Eighteen patients with endometrial adenocarcinoma were submitted to hysteroscopic injection of technetium-99m-labeled colloids and blue-dye subendometrially around the lesion followed by lymphoscintigraphic scans. The SLN was detected by direct visualization of blue-dye marked nodes and by a radio-guided surgery (RGS).

Results: Seventeen hysteroscopic procedures were satisfactory regarding the visualization of the uterine cavity. The compliance to the procedure was acceptable in 15 cases, with no severe complication. A hysterectomy and bilateral salpingo-oophorectomy were performed in all cases, and pelvic lymphadenectomy in 14 cases. The RGS detected a total of 45 SLN with a mean of 3 SLN/patient (range 2 to 4). Blue-dye uptake was observed in 6 (33%) cases. No case presented blue-dye uptake and radioactive-colloid negativity.

Conclusion: The results seem promising for further controlled studies.

Background: This study aimed to investigate the risk factors related to the failure of initial combined local methotrexate (MTX) treatment and minimally invasive surgery for late cesarean scar pregnancy (CSP).

Methods: This retrospective case-control study was conducted between January 2016 and December 2023, involving patients with late CSP (≥ 8 weeks) who received local MTX injection combined with either hysteroscopic or laparoscopic surgery. Cesarean scar pregnancy was classified as type I, II, or III based on the direction of growth of the gestational sac and the residual myometrial thickness as assessed by ultrasound.
