We're thrilled to announce the publication of a groundbreaking systematic review and meta-analysis led by Dr. Greg Marchand and the dedicated research team at the Marchand Institute for Minimally Invasive Surgery! Titled "Laparoendoscopic Single-Site Surgery Versus Conventional Laparoscopic Surgery in Ovarian Cystectomy: A Meta-Analysis", this comprehensive study compares two advanced minimally invasive techniques for removing benign ovarian cysts — Laparoendoscopic Single-Site Surgery (LESS) (using a single small incision, often hidden at the umbilicus for superior cosmetic results) and Conventional Laparoscopic Surgery (CLS) (using multiple small incisions). Analyzing data from 9 studies involving 1,368 women, the meta-analysis reveals compelling insights: LESS is associated with longer operative times (by about 9.4 minutes on average), likely due to the technical demands of working through a single port. However, patients undergoing LESS benefit from a shorter hospital stay (reduced by approximately 0.26 days). Importantly, there are no significant differences in key safety outcomes: postoperative pain scores (at 6 and 24 hours), estimated blood loss, need for opioid analgesics, drop in hemoglobin levels, or overall complication rates. These findings strengthen the evidence that LESS is a safe, effective, and viable alternative to conventional laparoscopy for women with benign ovarian cysts — offering faster recovery and excellent cosmetic advantages while maintaining comparable safety and pain profiles. This work adds valuable high-level evidence to the field of minimally invasive gynecologic surgery and reflects the Marchand Institute's ongoing commitment to advancing women's health through rigorous, volunteer-driven research.
