Early readmission after ileoanal pouch surgery.

PURPOSE: This study was designed to evaluate factors that might be predictive of readmission and early and long-term outcomes for patients readmitted after ileal pouch-anal anastomosis.

METHODS: Data for patients readmitted within 30 days after ileal pouch-anal anastomosis were identified from a prospectively maintained database and compared with the remaining patients. Early and delayed outcomes for readmitted patients, including long-term functional outcomes and quality of life, were evaluated. Potential predictors of readmission were assessed using a multivariate analysis of factors.

RESULTS: Of 3,410 patients who underwent ileal pouch-anal anastomosis from 1984 to 2008, 410 (12%) were readmitted. Reasons for readmission included ileus, obstruction or dyselectrolytemia (54.9%), surgical site infection (19.8%), anastomotic problems (9.8%), and thrombotic (3.4%), hemorrhagic (3.2%), infectious (2.9%), cardiac (1.2%), and miscellaneous (4.3%) complications. Thirty-two (7.8%) patients underwent reoperation; 74 (18%) required invasive nonoperative interventions. Median hospital stay for readmission was four (range, 1-52) days. Readmitted patients had worse long-term functional results (P = 0.015) and social (P = 0.024), work (P = 0.008), and sexual (P = 0.046) restriction as compared with patients who were not readmitted. The Cleveland Global Quality of Life (P = 0.018) and physical SF-36 (P = 0.008) scores were also significantly lower for readmitted patients. On multivariate analysis, comorbid conditions (P = 0.014, odds ratio = 1.36), laparoscopic technique (P = 0.008, odds ratio = 1.8), proctocolectomy (rather than initial subtotal colectomy) at ileal pouch-anal anastomosis (P < 0.001, odds ratio = 1.55), and postoperative blood transfusion (P = 0.02, odds ratio = 1.54) were independently associated with readmission.

CONCLUSION: Early readmission after ileal pouch-anal anastomosis is common. Associated comorbidity, laparoscopic approach, reconstruction of the ileal pouch-anal anastomosis at the index surgery, and postoperative blood transfusion are associated with readmission.
