Background: Infection due to multidrug-resistant Klebsiella pneumoniae is a common cause of graft resection after small bowel transplantation. We report a failed case in which the intestinal graft was resected 18 days after the operation due to postoperative infection with multidrug-resistant K pneumoniae and a literature review of other common causes of small bowel transplantation failure have been reported.
Methods: A female, 29 years of age, underwent partial living small bowel transplantation for short bowel syndrome. After the operation, the patient was infected with multidrug-resistant K pneumoniae, even though various anti-infective regimens were employed. It further developed into sepsis and disseminated into intravascular coagulation, leading to exfoliation and necrosis of the intestinal mucosa. Finally, the intestinal graft had to be resected to save the patient's life.
Results: Multidrug-resistant K pneumoniae infection often affects the biological function of intestinal grafts and can even lead to necrosis. Other common causes of failure, including postoperative infection, rejection, post-transplantation lymphoproliferative disorder, graft-vs-host disease, surgical complications, and other related diseases, were also discussed throughout the literature review.
Conclusions: Pathogenesis due to diverse and interrelated factors makes the survival of intestinal allografts a great challenge. Therefore, only by fully understanding and mastering the common causes of surgical failure can the success rate of small bowel transplantation be effectively improved.
