Article Abstract
Robotic colorectal surgery (RCS) offers enhanced dexterity and visualization, potentially improving oncologic and perioperative outcomes compared to laparoscopic colorectal surgery (LCS). However, its comparative benefits remain unclear. This systematic review and meta-analysis, registered in PROSPERO (CRD420251036097), evaluated randomized controlled trials comparing RCS and LCS for colorectal cancer. The primary outcomes were time to bowel function, major complications, and total mesorectal excision (TME) completeness. Secondary outcomes included operative time, blood loss, lymph node yield, conversion to open surgery, hospital stay, anastomotic leakage, CRM involvement, and R0 resection. The meta-analysis incorporated seven randomized controlled trials involving 1731 patients: 869 underwent robotic-assisted surgery, while 862 underwent conventional laparoscopy. Robotic surgery significantly improved time to bowel function (MD - 0.62 days), reduced major complications (OR 0.70), and lowered conversion rates (OR 0.27) and CRM involvement (OR 0.62) compared to laparoscopy. Operative time was longer (MD + 22.7 min), while laparoscopic surgery yielded slightly higher lymph node counts (MD + 0.53). No significant differences were found in TME completeness, R0 resection, or anastomotic leaks. RCS has meaningful advantages in bowel recovery, surgical precision, and intraoperative outcomes, supporting its broader adoption in the surgical management of colorectal cancer.

Impact of diagnostic laparoscopy on resectability and treatment strategy in FIGO III-IV ovarian cancer.
Arch Gynecol Obstet
September 2025
Department of Obstetrics and Gynecology, University Medical Center Freiburg, Freiburg, Germany.
Objective: To investigate the clinical utility of diagnostic laparoscopy in guiding treatment strategy and surgical outcomes for patients with advanced-stage ovarian cancer, specifically regarding operability assessment and the likelihood of complete cytoreduction.
Methods: This retrospective cohort study analyzed 183 patients with histologically confirmed International Federation of Gynecology and Obstetrics (FIGO) stage III-IV ovarian cancer treated with curative intent between January 2018 and December 2023 at a tertiary referral center. Patients were divided into two groups: those who underwent diagnostic laparoscopy prior to primary treatment (n = 80) and those managed without laparoscopy (n = 103).
Multimodal machine learning for staging laparoscopy: a combined image analysis and morphologic tool for the discrimination of peritoneal metastasis.
Int J Surg
September 2025
Department of Human Structure and Repair, Ghent University Faculty of Medicine, Belgium.
Background: Staging laparoscopy (SL) is an essential procedure for peritoneal metastasis (PM) detection. Although surgeons are expected to differentiate between benign and malignant lesions intraoperatively, this task remains difficult and error-prone. The aim of this study was to develop a novel multimodal machine learning (MML) model to differentiate PM from benign lesions by integrating morphologic characteristics with intraoperative SL images.

Background: Enucleation has the advantages of preserving function and avoiding pancreaticoduodenectomy for benign and low-grade malignant neoplasms in the pancreatic head. However, laparoscopic enucleation (LEn) of pancreatic head tumors remains challenging in terms of bleeding control and duct integrity preservation because of the complicated blood supply to the pancreatic head and the adjacent relationships of lesions with the main pancreatic duct (MPD), especially for deep-seated or broad-based lesions. Here, we developed a novel dual-arterial occlusion technique to facilitate LEn of pancreatic head tumors and evaluated its feasibility and safety.

Background: Low-grade endometrial stromal sarcoma (LG-ESS) is a rare malignant tumor of the female reproductive system with atypical clinical symptoms and slow progression.
Case: A 44-year-old female with a history of intermittent severe dysmenorrhea, previous laparoscopic myomectomy, and uterine artery embolization (UAE) presented with rapidly enlarging pelvic masses. Imaging revealed uterine masses suggestive of leiomyomas, although an adnexal origin could not be excluded.

We describe a case of a 64-year-old obese woman with a history of severe acute cholecystitis and choledocholithias who underwent laparoscopic cholecystectomy in our clinic after endoscopic treatment by sphincterotomy and stent insertion. On the first operative day, a significant bile leakage of 400 ml appeared in the drainage. An immediate surgical revision was performed, starting by laparoscopy with conversion to open surgery.
