What are some prospective thesis topics related to upper Gastrointestinal (GI) surgeries and general surgery that can improve patient outcomes in adults with underlying medical conditions?

Prospective Thesis Topics for Upper GI and General Surgery

For a three-year prospective thesis focusing on upper GI surgery with general surgery components, I recommend investigating perioperative nutritional optimization protocols and their impact on surgical complications, mortality, and quality of life—this addresses a critical gap where current evidence remains insufficient despite clear associations between malnutrition and poor outcomes.

High-Priority Research Areas Based on Current Evidence Gaps

1. Perioperative Nutritional Optimization in Upper GI Surgery

Primary Topic: Prospective evaluation of structured preoperative nutritional protocols in malnourished patients undergoing major upper GI surgery

• Malnutrition is an independent risk factor for poor postoperative outcomes, including increased abdominal septic complications and higher mortality rates, yet optimal nutritional interventions remain unknown 1
• Current guidelines acknowledge that improvements in preoperative management can reduce stoma formation rates, lower anastomotic leakage, and reduce hospital stay, but lack specific protocols 1
• You could prospectively compare different nutritional optimization strategies (enteral nutrition vs. peripheral parenteral nutrition vs. combined approaches) in patients with documented malnutrition undergoing esophagectomy, gastrectomy, or pancreatic surgery 1
• Measure primary outcomes: anastomotic leak rates, 30-day mortality, infectious complications, and quality of life at 3,6, and 12 months 1

Why this matters clinically:

• Ten procedure groups account for 62% of complications in general surgery, with upper GI resections (esophagectomy, gastrectomy) and small intestine resections being major contributors 2
• Postoperative morbidity following major gastrointestinal procedures remains substantial despite advances in minimally invasive surgery 3

2. Early Detection and Management of Anastomotic Leaks

Secondary Topic: Prospective validation of early warning systems for anastomotic leak detection after upper GI surgery

• Anastomotic leaks after esophagectomy and gastric resections are among the most feared complications with significant clinical and economic consequences 3
• Develop and prospectively validate a clinical scoring system combining biomarkers (CRP, procalcitonin), clinical parameters, and imaging findings to predict anastomotic leaks within 72 hours postoperatively 3
• Machine learning algorithms are emerging to assist in anticipating complications, but require prospective validation 3
• Include quality of life assessments, as this is surprisingly underreported in surgical literature despite good outcomes in survivors 4

3. Enhanced Recovery After Surgery (ERAS) Protocol Implementation

Tertiary Topic: Prospective implementation study of comprehensive ERAS protocols in upper GI surgery

• ERAS protocols have led to reduced length of hospital stay, reduced morbidity, and improved quality of life in elective gastrointestinal surgery 1
• Prospectively implement and evaluate a standardized ERAS protocol specifically tailored for upper GI cancer surgery, measuring compliance rates, complication patterns, and patient-reported outcomes 3
• Focus on early oral nutrition starting on the day of surgery, as recommended but not universally practiced 1
• Document barriers to mobilization during the first postoperative week (fatigue, pain) and test interventions to overcome them 4

4. Quality Indicators in Upper GI Endoscopy and Early Cancer Detection

Alternative Topic: Prospective audit of diagnostic quality indicators in upper GI endoscopy

• There is an unacceptably high rate of failure to diagnose cancer at endoscopy despite technical competence 1
• Prospectively implement and measure adherence to the 38 quality recommendations from BSG/AUGIS, focusing on early neoplasia detection rates before and after structured quality improvement interventions 1
• This could include both diagnostic endoscopy and correlation with subsequent surgical findings in patients who proceed to resection 1
• Measure impact on stage at diagnosis and subsequent surgical outcomes 1

5. Outcomes in Elderly Patients Undergoing Upper GI Surgery

Alternative Topic: Prospective cohort study of frailty assessment and outcomes in elderly patients

• Elderly patients have 1.2-2 times higher perioperative morbidity and 2.9-6.7 times higher mortality after major GI surgery 5
• Cardiac, pulmonary, and urologic complications are significantly more common in elderly patients, yet quality measures don't adequately address these 5
• Prospectively assess frailty using validated tools (e.g., Clinical Frailty Scale) and correlate with specific complication patterns and quality of life outcomes in patients >75 years undergoing upper GI surgery 5
• Include patient-reported outcome measures, which are surprisingly sparse in this vulnerable population 4

Practical Considerations for Your Three-Year Timeline

Year 1: Protocol Development and Ethics Approval

• Develop detailed study protocols with clear inclusion/exclusion criteria 1
• Obtain ethics approval and establish data collection systems 1
• Begin pilot enrollment to refine protocols 1

Year 2: Active Enrollment and Data Collection

• Prospective patient enrollment with standardized data collection 1
• Real-time monitoring of complications and interventions 3
• Interim analysis to ensure adequate power and adjust if needed 1

Year 3: Follow-up Completion and Analysis

• Complete 12-month follow-up for quality of life assessments 1
• Statistical analysis and manuscript preparation 1
• Consider multicenter collaboration if single-center volume is insufficient 6

Critical Pitfalls to Avoid

Common methodological errors:

• Don't focus solely on mortality and morbidity—include quality of life and patient-reported outcomes, which are severely underreported 4
• Avoid retrospective designs when prospective data collection is feasible, as you'll miss important patient-centered outcomes 4
• Don't ignore the protracted critical period following surgery—complications often manifest beyond the immediate postoperative period 4

Practical considerations:

• Ensure adequate patient volume by focusing on high-volume procedures at your institution 2, 6
• If your center has low gastrectomy volume but high overall upper GI surgery volume, outcomes may still be equivalent to high-volume centers 6
• Consider that colectomy, small intestine resection, and inpatient cholecystectomy account for the greatest share of adverse events if you need to broaden beyond pure upper GI 2

Patient selection:

• Include both elective and emergency cases, as emergency surgery represents a major challenge with 34% one-year mortality 4
• Don't exclude elderly or frail patients—they represent the population most in need of quality improvement 5, 4
