Gallstone ileus is a rare disease and accounts for 1%-4% of all cases of mechanical intestinal obstruction. It usually occurs in the elderly with a female predominance and may result in a high mortality rate. Its diagnosis is difficult and early diagnosis could reduce the mortality. Surgery remains the mainstay of treatment. We report two cases of gallstone ileus. The first was a 78-year old woman who had a 2-d history of vomiting and epigastralgia. Plain abdominal film suggested small bowel obstruction clinically attributed to adhesions. Later on, gallstone ileus was diagnosed by abdominal computed tomography (CT) based on the presence of pneumobilia, bowel obstruction, and an ectopic stone within the jejunum. She underwent emergent laparotomy with a one-stage procedure of enterolithotomy, cholecystectomy and fistula repair. The second case was a 76-year old man with a 1-wk history of epigastralgia. Plain abdominal film showed two round calcified stones in the right upper quadrant. Fistulography confirmed the presence of a cholecystoduodenal fistula and gallstone ileus was also diagnosed by abdominal CT. We attempted to remove the stones endoscopically, but failed leading to an emergent laparotomy and the same one-stage procedure as for the first case. The postoperative courses of the two cases were uneventful. Inspired by these 2 cases we reviewed the literature on the cause, diagnosis and treatment of gallstone ileus.

Abstract

Prognostic study, level III; therapeutic study, level IV.

Gastric bleeding due to graft-vs-host-disease (GVHD) is rare after allogeneic hematopoietic stem cell transplantation, and the interrelationship between endoscopic and histologic assessment has not been well studied. Four patients with documented gastric bleeding due to GVHD were evaluated retrospectively. The endoscopic findings varied markedly and included mild mucosal edema with focal erythema, diffuse erythema with mucosal oozing, and diffuse polypoid indurations with multiple bleeding ulcerations. The histologic features of endoscopic biopsy specimens also varied from scattered apoptotic epithelial cells in one end to denudation of the epithelium with crypt necrosis in the other. The endoscopic findings could not accurately predict the histologic grading of GVHD. Nevertheless, gastric bleeding resolved in 3 patients with increasing intensity of immunosuppression. There was significant disparity between the endoscopic and histologic assessment of the severity of GVHD, and careful adjustment of immunosuppressive therapy might be warranted.
