Popular Research Topics in General Surgery
Enhanced Recovery After Surgery (ERAS) protocols represent the most impactful and widely researched area in general surgery today, with studies consistently demonstrating significant reductions in length of stay, complications, and healthcare costs across multiple surgical subspecialties. 1
Current Hot Research Areas in General Surgery
1. Enhanced Recovery After Surgery (ERAS)
- Implementation across different surgical subspecialties
- Specific protocol elements and their individual contributions to outcomes
- Long-term outcomes and sustainability of ERAS programs
- Cost-effectiveness analyses and healthcare resource utilization
- Patient-reported outcomes and quality of life measures
ERAS research has expanded from its origins in colorectal surgery to virtually all surgical specialties, with the ERAS Society regularly publishing updated evidence-based guidelines 1. The multimodal approach focuses on:
- Preoperative optimization and patient education
- Minimally invasive techniques
- Optimal fluid management
- Multimodal pain management with opioid reduction
- Early mobilization and nutrition
2. Perioperative Pain Management
- Multimodal analgesia techniques to reduce opioid requirements
- Regional anesthesia applications in general surgery
- Novel analgesic medications and delivery systems
- Opioid-sparing protocols and their outcomes
- Prevention of chronic postsurgical pain
The World Society of Emergency Surgery (WSES) has published guidelines specifically addressing postoperative pain management in emergency general surgery, highlighting the importance of this research area 1.
3. Minimally Invasive Surgery Advancements
- Robotic-assisted surgery outcomes and cost-effectiveness
- Single-incision laparoscopic techniques
- Natural orifice transluminal endoscopic surgery (NOTES)
- Comparison of different minimally invasive approaches
- Training and learning curve analyses
4. Surgical Quality Improvement and Outcomes Research
- Standardized outcome reporting systems
- Risk prediction models and decision support tools
- Benchmark development for surgical procedures
- Implementation science in surgery
- Quality metrics that matter to patients
The consensus recommendations on assessing surgical quality interventions 1 emphasize the importance of standardized outcome reporting and benchmarking.
5. Bile Duct Injury Prevention and Management
- Techniques to reduce bile duct injuries during cholecystectomy
- Early detection methods and imaging protocols
- Optimal management strategies for different injury types
- Long-term outcomes after bile duct injury repair
- Prevention strategies and surgical technique modifications
The WSES guidelines for detection and management of bile duct injury during cholecystectomy 1 highlight this as a critical research area.
6. Perioperative Nutrition
- Immunonutrition before and after surgery
- Impact of malnutrition on surgical outcomes
- Prehabilitation programs including nutritional optimization
- Early oral feeding protocols after gastrointestinal surgery
- Management of sarcopenia in surgical patients
The ESPEN expert group recommendations 1 emphasize the importance of perioperative nutrition research, particularly in addressing sarcopenia and optimizing preoperative nutritional status.
7. Surgical Site Infection Prevention
- Novel antimicrobial technologies and dressings
- Preoperative decolonization protocols
- Perioperative antibiotic optimization
- Negative pressure wound therapy applications
- Bundle approaches to SSI prevention
Guidelines on surgical wound care interventions 1 highlight the ongoing research needs in this area, particularly regarding cost-effectiveness analyses and new intervention comparisons.
8. Emergency General Surgery
- Standardization of emergency general surgery care
- Risk stratification in emergency surgery patients
- Timing of intervention in acute surgical conditions
- Resource utilization and systems of care
- Outcomes improvement in high-risk emergency patients
The WSES guidelines for emergency laparotomy 1 demonstrate the growing research focus on optimizing emergency general surgery care.
9. Frailty and Geriatric Surgery
- Frailty assessment tools specific to surgical patients
- Prehabilitation for frail surgical patients
- Modified surgical approaches for elderly patients
- Postoperative delirium prevention and management
- Shared decision-making in high-risk elderly patients
10. Digital Health and Artificial Intelligence in Surgery
