General Surgery Research Topics (2025-2026)

1. Minimally Invasive & Robotic Surgery

• Robotic vs. laparoscopic surgery for colorectal cancer - Active area with strong meta-analytic evidence. The COMPARE Study (Ann Surg, 2025) compares oncologic outcomes across open, laparoscopic, and robotic platforms. Feasibility, cost-effectiveness, and learning curve are all open questions.
• Robotic vs. laparoscopic cholecystectomy - A 2025 meta-analysis with GRADE assessment shows mixed outcomes; gaps remain in long-term cost data.
• Minimally invasive surgery for pancreatic neuroendocrine tumors - A 2024 systematic review found MIS comparable to open but data are limited.

2. Colorectal Surgery

• Bowel preparation and SSI reduction - Gosavi et al. (2025) showed mechanical bowel prep + oral antibiotics significantly reduces surgical site infections and anastomotic leaks; still debated in specific populations.
• Negative pressure wound therapy (NPWT) for colorectal incisions - Wang et al. (2025) meta-analysis supports its use; implementation and cost in LMIC settings unexplored.
• Kono-S anastomosis in Crohn's disease - Lin et al. (2024) shows reduced recurrence; local audit or prospective cohort data could be valuable.
• Antibiotic selection for surgical site infection prophylaxis - Cephalosporins vs. non-cephalosporins in colorectal surgery: updated 2024 meta-analysis.

3. Hepatopancreaticobiliary (HPB) Surgery

• Perioperative enteral nutrition optimization - Bibliometric analysis (2024) highlights this as a growing research cluster; intervention studies are still needed.
• Predictors of acute pancreatitis recurrence - Systematic review (2025) identifies gaps in risk stratification after first episode.
• Hypertriglyceridemia-induced acute pancreatitis - Lu et al. (2025) maps the risk factor landscape; management protocols vary widely.

4. Bariatric & Metabolic Surgery

• GLP-1 agonists after failed bariatric surgery - Hot topic given semaglutide/tirzepatide rise. 2024 meta-analysis reviewed efficacy for weight regain post-bariatric surgery. Real-world comparative data are scarce.
• Long-term metabolic outcomes of sleeve gastrectomy vs. RYGB - Ongoing controversy; local registry studies are publishable.

5. Surgical Oncology

• Circulating tumor DNA (ctDNA) in colorectal cancer - Zhang et al. (2025) identified ctDNA surveillance as the hottest emerging topic in CRC research.
• Omics approaches in neuroblastoma - Genomic/proteomic characterization guiding surgical decision-making.
• Non-small cell lung cancer: surgery vs. SBRT - 2025 ACCP guidelines still show controversy for stage I/II; real-world institutional data are valuable.

6. Surgical Site Infection & Perioperative Care

• Wound care bundles and SSI reduction - Always fundable, locally relevant, and fast to execute as an audit or QI study.
• Enhanced Recovery After Surgery (ERAS) protocol compliance and outcomes - Adherence rates and outcome heterogeneity across institutions.
• Perioperative glycemic control - Tight control vs. liberal: outcomes in elective vs. emergency settings.

7. Emergency Surgery

• Non-operative management of appendicitis - Antibiotic-first approach: long-term failure rates, risk stratification, and patient selection.
• Management of complicated hernias - Incarcerated/strangulated: open vs. laparoscopic, mesh use, recurrence.
• Damage control surgery outcomes - Timing of definitive repair, physiologic thresholds.

8. Technology & AI in Surgery

• AI-assisted intraoperative decision support - Bleeding detection, anatomy recognition, and complication prediction.
• Large language models in surgical documentation and triage - A 2025 NYU study benchmarked general-purpose LLMs against clinical AI.
• Simulation and surgical training metrics - Objective skill assessment, resident competency.
