Chronic graft versus host disease with small bowel obstruction after unrelated hematopoietic stem cell transplantation in a patient with acute myeloid leukemia

Graft-versus-host disease complicated with small bowel obstruction in children: A case report

Graft-versus-host disease (GvHD) is a severe complication following hematopoietic cell transplantation (HCT). The clinical manifestations of GvHD can affect multiple systems. Although gastrointestinal (GI) GvHD is common, GI obstruction complications are rare. Here, we present a case of GI-GvHD after HCT for acute myeloid leukemia (AML) in a young girl from China. The patient suffered from watery diarrhea, which progressed to bloody diarrhea 40 days after HCT. She experienced prolonged and repeated mucous or bloody stool after the withdrawal of cyclosporine and the gradual reduction in methylprednisolone. The plain abdominal radiography and computed tomographic (CT) scan showed apparent bowel wall thickening and intestinal stenosis 10 months after HCT. Finally, the patient underwent surgery to remove the small intestinal stenosis at the age of 26 months. The patient recovered with the help of appropriate medical therapies and nutritional support during hospitalization. She remained stable, and there was no recurrence of GI symptoms 16 months after the surgery. In summary, surgery may be an optimal treatment for GvHD patients with persistent bowel obstruction and failure of appropriate immunosuppressive therapies.

Small bowel necrosis and perforation due to sodium polystyrene sulfonate in the setting of graft versus host disease and fulminant Clostridium difficile infection

Gastrointestinal injury is a common adverse event associated with use of sodium polystyrene sulfonate (SPS), tradename Kayexalate. Risk factors for SPS-mediated gastrointestinal necrosis include chronic kidney disease, solid organ transplant recipiency and recent surgery. This report presents a patient with past medical history significant for acute myeloid leukemia (AML) complicated by graft versus host disease (GvHD) and Clostridium difficile colitis who initially presented with small bowel obstruction. She was taken to the operating room and her small bowel pathology was significant for transmural necrosis with SPS crystals in the granulation tissue, despite last receiving SPS over a year ago. Previous mucosal damage should be considered as a risk factor for SPS-mediated injury and the effects of this medication may occur longer than previously thought.

Surgical treatment of intestinal complications of graft versus host disease in the pediatric population: Case series and review of literature

BACKGROUND/PURPOSE

Intestinal complications of acute graft-versus-host disease (aGVHD) include hemorrhage and perforation in the short-term, and stricture with bowel obstruction in the long-term. As medical management of severe aGVHD has improved, more patients are surviving even advanced stages of intestinal aGVHD. This review summarizes the available pediatric literature on surgical treatment of complications of intestinal GVHD.

METHODS

A systematic review was performed using PubMed, Cochrane, Embase, and Scopus databases. Any publication that addressed surgical treatment of acute and chronic intestinal GVHD in the pediatric population was reviewed in detail. Furthermore, we included information on 5 additional patients from the institutions of this review's authors, which had not been previously published.

RESULTS

We identified 8 studies, comprising 13 patients. Surgical interventions were undertaken for a variety of intestinal GVHD complications, including small bowel obstruction owing to stricture (n=8), enterocutaneous fistulae (n=2), gastrointestinal hemorrhage/perforation (n=1 each), and esophageal stricture (n=1). Among eight patients with bowel obstruction as an indication, pathology revealed ulceration with fibrosis in all but one; 3 had signs of persistent GVHD. Surgical mortality was reported in 4 patients (31%) at an average of 6weeks postoperatively. The median overall follow-up time was 20months (IQR, 2-21).

CONCLUSIONS

Although intestinal aGVHD management is almost exclusively medical, a small subset of patients develops complications of intestinal GVHD that require surgical intervention. With expanding indications for stem cell transplantation as well as improved survival after previously fatal bouts of intestinal aGVHD, it is likely that surgical intervention will become more common in these complicated patients.
