Background
The majority of colorectal complications after kidney transplantation reportedly occur <1 year of transplant. We aimed to identify differences in complications in the early and late posttransplant period.
Methods
We retrospectively reviewed kidney transplant recipients undergoing colorectal resection from 1 June 2000 to 1 June 2012 at a single institution, comparing patients by posttransplant year (<1 vs. >1 year). Measured outcomes included major complications, postoperative length of stay, perioperative mortality, reoperations, and readmissions.
Results
We identified 45 patients aged 31–77 (median 55). Gastrointestinal malignancy (31 %), diverticular disease (24 %), and ischemic colitis (16 %) were the most common indications for surgery. The early group (n = 9) had more cases of ischemic colitis (44 vs. 6 %, p = 0.01), emergent operations (100 vs. 33 %, p = 0.0003), blood transfusion (78 vs. 31 %, p = 0.02), longer length of stay (23.2 ± 12 vs. 11.7 ± 10 days, p = 0.02), and higher mortality rate (33 vs. 6 %, p = 0.05 compared to the late group (n = 36)). There were no significant differences in major complications, reoperations, or readmissions.
Conclusions
Kidney transplant recipients undergoing colorectal resection <1 year of transplant have a higher incidence of emergency surgery and ischemic colitis compared with those with >1 year posttransplant. Despite these findings, patients with grafts <1 year had a similar postoperative complication rate to patients with grafts >1 year.
