Transverse Colonic Perforation in Renal Transplant Recipients During the Early Postoperative Period: A Case Series.

There are very few cases of nondiverticulitis episodes of colonic perforation in the acute postoperative period following kidney transplantation described in the literature. Various nondiverticular causes of colonic perforations include ischemia, malignancy, cytomegalovirus (CMV) enterocolitis, and nonobstructive colonic dilatation. Immunosuppressive medication can contribute to colonic perforation, placing kidney recipients at risk for these complications. Since 2011, there have been 2 cases of transverse colonic perforation in the early postoperative period following renal transplantation at our institution. Both patients underwent urgent exploratory laparotomy with resection of perforated transverse colon and creation of a proximal colostomy. The aim of this study is to review the cases of colonic perforation following renal transplantation to gain a greater understanding of this rare occurrence. Despite the lack of a clear cause of perforation, it is imperative to have a high index of suspicion for colonic perforations in these immunocompromised patients to provide prompt surgical management and improved outcomes.
