About
Colleen Tewksbury is a leading researcher in bariatric and metabolic surgery, with a focus on optimizing perioperative outcomes for high-risk patient populations. Her work critically examines the safety profiles of common weight-loss procedures, particularly in patients with complex cardiac histories. In her landmark 2019 study, Tewksbury demonstrated that laparoscopic sleeve gastrectomy carries significantly lower perioperative mortality, including sudden cardiac death, compared to Roux-en-Y gastric bypass in patients with prior cardiac conditions—a finding that has shaped clinical decision-making and patient counseling. More recently, her 2025 analysis of over 284,000 patients from the MBSAQIP database provided the largest-ever evaluation of staple line reinforcement during sleeve gastrectomy, offering evidence-based guidance on surgical technique. With her research cited in major surgical guidelines and practice-changing protocols, Tewksbury’s contributions have directly improved patient safety and risk stratification in metabolic surgery. Her work stands as a vital resource for surgeons and trainees navigating the complexities of bariatric care.
