Intraperitoneal Barium From Gastrointestinal Perforations: Reassessment of the Prognosis and Long-Term Effects.

Abstract

OBJECTIVE. The purpose of this study was to reassess the outcome and potential consequences of intraperitoneal barium leakage during radiologic evaluation of the gastrointestinal tract. MATERIALS AND METHODS. This retrospective study included 18 patients who had significant intraperitoneal leakage of barium from gastrointestinal perforations that were not suspected or diagnosed before the radiologic procedures. This complication occurred during a barium enema examination in nine patients, an upper gastrointestinal study in seven, and a small bowel series in two patients. All patients underwent urgent laparotomy for repair of perforation, with vigorous peritoneal lavage and antibiotic therapy. RESULTS. All patients had an uneventful recovery and were followed for 4-17 years (mean, 8.5 years). Radiographs obtained during this interval showed that a significant amount of residual barium was retained in the abdominal cavity. Six patients had a total of 10 subsequent abdominal operations for unrelated conditions, and some had developed barium granulomas and peritoneal adhesions. However, none of the patients in this series experienced intestinal obstruction or any clinical symptoms related to barium deposits in the abdominal cavity. CONCLUSION. Intraperitoneal leakage of barium is a rare complication of radiologic gastrointestinal examinations, and this series of 18 cases reflects 3 decades of experience at two major medical centers. The presented data indicate that the commonly held and perpetuated concept about the high rate of morbidity and mortality of this complication would not be valid in the modern era of medical and surgical management.
