Abstract
PurposeReoperation after radical cystectomy (RC) is common but the types of reoperation after RC and associated risk factors have not been fully characterized. Here, we provide a detailed, contemporary account of the factors that drive surgical reoperation within the first 30-days after surgery, identify at risk patient populations, and describe common reoperations. Materials and methodsThe American College of Surgeons National Surgical Quality Improvement Program database (2012–2017) was analyzed to identify 30-day reoperation rates after RC. Captured variables included demographic, preoperative, operative, and postoperative characteristics. Postoperative characteristics included complications, including types of reoperation, length of stay, unplanned readmissions, and discharge destination. Pearson chi-squared and multivariable logistic regression models were used for analysis. ResultsA total of 10,848 patients underwent RC and there were 633 (5.84%) unplanned reoperations. On multivariable logistic regression, patient factors associated with increased risk of reoperation included longer operative times at index procedure (>90th percentile operative time) (OR1.41 [1.08–1.83], P = 0.02), smoking (OR1.34 [1.11–1.63], P < 0.01), obesity (BMI≥30) (OR 1.29 [1.04–1.60], P = 0.02) and chronic obstructive pulmonary disease (OR1.74 [1.36–2.3], P < 0.01). Other significant factors included clinically significant hypertension, perioperative blood transfusion, and male sex. The most common reoperation procedures were those performed on the gastrointestinal tract, accounting for 60.59% (349) of all reoperations, followed by skin/subcutaneous procedures 14.76% (85), followed by Genitourinary procedures at 8.16% (47). Patients who underwent reoperation were at higher risk for readmission, discharge to a facility, and death (P < 0.01). ConclusionReoperation after RC is associated with approximately 5% rate of reoperation within 30 days of surgery. The most common reason for reoperation was related to the gastrointestinal tract, accounting for more than 60% of all reoperations. Risk factors for reoperation included longer surgical times, smoking, obesity, chronic obstructive pulmonary disease, perioperative blood transfusion, and clinically significant hypertension. Knowledge of these factors can aid in operative planning and counseling and lead to possible strategies to reduce reoperations in the early perioperative setting.
