A multicenter randomized clinical trial published in JAMA Surgery compared high versus low ligation of the inferior mesenteric artery (IMA) during laparoscopic and robotic anterior resection for Stage I–III rectal cancer. The modified intention-to-treat analysis included 293 patients and evaluated symptomatic anastomotic leakage, postoperative morbidity, bowel function, and quality of life.

Key Findings

  • Symptomatic anastomotic leakage occurred in:
    • 4.9% following low IMA ligation
    • 6.0% following high IMA ligation
  • The difference was not statistically significant.
  • Overall 30-day postoperative morbidity was numerically lower after low ligation but failed to reach statistical significance.
  • At one year, bowel function, urinary function, sexual function, quality-of-life scores, and the incidence of major Low Anterior Resection Syndrome (LARS) were similar between both techniques.

Clinical Relevance

This high-quality randomized trial suggests that the level of IMA ligation should not be chosen solely to reduce anastomotic leakage. Instead, operative strategy should be individualized according to tumor location, vascular anatomy, lymph node clearance, bowel perfusion, and tension-free anastomosis. Surgical judgment remains more important than adopting a single standardized ligation strategy.

Large eTEP Ventral Hernia Review Highlights Defect Size and Posterior Layer Integrity as Key Safety Factors

A comprehensive evidence review published in the Journal of Gastrointestinal Surgery combined data from the Americas Hernia Collaborative Quality Collaborative (ACHQC), published literature, expert consensus, and AI-assisted evidence synthesis to evaluate outcomes following enhanced-view totally extraperitoneal (eTEP) ventral hernia repair.

The review analyzed 8,434 elective adult eTEP procedures.

Key Findings

Thirty-day outcomes demonstrated:

  • Readmission: 2.4%
  • Reoperation: 1.3%
  • Surgical site infection: 1.1%
  • Surgical site occurrence (SSO): 9.5%
  • SSO requiring intervention: 1.8%

The strongest predictor of postoperative complications was hernia defect width:

  • Defects <4 cm had intervention rates of only 0.5%
  • Defects >10 cm demonstrated rates approaching 4.6%

Transversus abdominis release (TAR) prolonged hospital stay but was not independently associated with increased readmission or reoperation.

Clinical Relevance

For advanced abdominal wall surgeons, successful eTEP repair depends primarily on meticulous retromuscular dissection, preservation of the posterior sheath, careful prevention of internal herniation, and appropriate patient selection rather than whether the operation is performed laparoscopically or robotically.

Comprehensive HPB Review Supports Selective, Evidence-Based Expansion of Robotic Surgery

A major evidence review published in the Journal of Surgical Research evaluated the evolution of robotic hepatopancreatobiliary surgery from 2000 through early 2026.

The review concludes that robotic surgery has progressed well beyond feasibility studies but should remain procedure-specific.

Key Findings

  • Robotic liver surgery offers outcomes comparable to laparoscopic and open surgery in carefully selected patients while potentially reducing blood loss and conversion rates.
  • Robotic distal pancreatectomy demonstrates more consistent perioperative advantages over laparoscopic distal pancreatectomy.
  • Robotic pancreatoduodenectomy has now reached randomized clinical evaluation, demonstrating comparable morbidity with faster recovery in experienced high-volume centers.
  • Robotic biliary reconstruction remains technically demanding and should currently be concentrated in specialized referral centers.

Clinical Relevance

The review emphasizes that robotic adoption should be indication-driven rather than technology-driven. Structured training, institutional experience, standardized reporting, and careful patient selection remain essential before expanding robotic HPB practice.

Laparoscopic Repair Successfully Managed Proximal Ureteral Transection During Para-Aortic Lymphadenectomy

A video article published in the Journal of the Turkish German Gynecological Association demonstrated successful laparoscopic repair of an intraoperatively recognized proximal ureteral transection sustained during para-aortic lymphadenectomy for high-risk endometrial carcinoma.

The reconstruction consisted of:

  • Tension-free ureteroureterostomy
  • Double-J ureteric stent placement
  • Careful preservation of ureteral vascular supply
  • Avoidance of conversion to open surgery

Clinical Relevance

This report highlights the importance of immediate recognition of ureteric injury and demonstrates that advanced minimally invasive reconstructive techniques can successfully manage this serious complication while avoiding laparotomy in experienced hands.

Oliceridine-Based Analgesia Accelerated Gastrointestinal Recovery Following Laparoscopic Radical Gastrectomy

A randomized double-blind clinical trial compared patient-controlled intravenous analgesia using oliceridine versus sufentanil following laparoscopic radical gastrectomy.

Ninety-six patients completed the study.

Key Findings

Compared with sufentanil, oliceridine resulted in:

  • Earlier first flatus
  • Earlier bowel movement
  • Faster resumption of oral intake
  • Lower postoperative nausea
  • Reduced vomiting
  • Earlier ambulation
  • Approximately one-day shorter hospital stay

Pain control remained comparable between both groups, and neither group experienced respiratory depression.

Clinical Relevance

Analgesic selection may represent an important modifiable component of Enhanced Recovery After Surgery (ERAS) protocols, particularly in upper gastrointestinal cancer surgery where early feeding and bowel recovery are critical.

ICG Fluorescence Imaging Demonstrates Feasibility but Limited Predictive Value After Laparoscopic Ovarian Surgery

A prospective feasibility study evaluated indocyanine green (ICG) fluorescence imaging following laparoscopic ovarian cystectomy and plasmajet treatment for benign ovarian cysts.

Key Findings

  • Successful fluorescence visualization occurred in all 45 patients.
  • No ICG-related adverse events were observed.
  • Fluorescence quality was generally excellent.
  • However, fluorescence intensity did not correlate with ovarian reserve markers.
  • Anti-Müllerian hormone levels declined at six months with partial recovery by one year.
  • Antral follicle count increased during follow-up.

Clinical Relevance

Although ICG fluorescence appears technically safe and feasible for assessing ovarian perfusion, current evidence does not support its use as a reliable intraoperative predictor of long-term fertility preservation or ovarian reserve.

Force-Feedback Robotic Liver Resection Shows Promise but Highlights Early Technical Limitations

An early clinical experience published in the Asian Journal of Endoscopic Surgery reported the first eight robotic liver resections performed using the Saroa Surgical System, a new robotic platform incorporating force-feedback technology.

Key Findings

  • Low median blood loss.
  • Three procedures required conversion to laparoscopy.
  • One patient developed Grade IIIa bile leakage following repeat hepatectomy.
  • Advantages included tactile feedback and compatibility with conventional laparoscopic workflow.
  • Limitations included restricted instrument range, reduced grasping force, and limited instrument availability.

Clinical Relevance

The study provides valuable real-world experience beyond promotional reports and reminds surgeons that careful patient selection, gradual adoption, and readiness for laparoscopic conversion remain essential during the introduction of new robotic technologies.

Key Takeaway

Today's evidence emphasizes that successful minimally invasive surgery depends on individualized decision-making rather than uniform technical choices. Across colorectal, HPB, hernia, gynecologic, bariatric, and robotic surgery, patient selection, anatomical understanding, structured training, meticulous operative technique, and evidence-based perioperative care remain the primary drivers of improved outcomes, while emerging technologies continue to serve as valuable adjuncts rather than replacements for sound surgical judgment.
