Surgical Treatment of Severe Bowel Obstruction as a Rare Complication Following Allogenic Hematopoietic Stem Cell Transplantation

Abstract

Gastrointestinal graft-versus-host disease (GVHD) and cytomegalovirus (CMV) disease are common complications occurring after allogeneic hematopoietic stem cell transplantation (allo-HSCT), and contribute to a high degree of morbidity and mortality associated with allo-HSCT. Herein, we present a patient with severe intestinal GVHD complicated by recurring CMV enteritis, which overall resulted in severe terminal ileum stenosis. The patient underwent laparoscopic ileocecal resection that significantly reduced symptoms and possibly prevented the development of fulminant ileus. Surgical treatment is rarely used in the treatment of gastrointestinal GVHD; however, the current patient history illustrates that patients with inadequate symptom control and severe inflammatory bowel stenosis can be successfully managed with surgery. We also review published case reports on surgical treatment for severe gastrointestinal GVHD.
