Recurrence after the first episode of PSP in children is frequent and is difficult to predict by CT findings. VATS is safe and effective in preventing recurrences. Surgical intervention may be an attractive alternative in patients who require chest tube drainage for the first episode of PSP.

The authors reviewed the radiographic findings in 19 patients with phytobezoars of the small bowel. The most common predisposing causes were previous gastric outlet surgery and persimmon ingestion. Twelve patients underwent contrast material-enhanced studies of the upper gastrointestinal tract, and one patient underwent a barium enema study. These examinations revealed four gastric, two duodenal, and eight small bowel phytobezoars in 10 patients. The obstruction caused by small bowel phytobezoars frequently occurred in the jejunum or proximal ileum, more proximally than has been reported in previous series. Barium studies are useful in differentiating obstruction due to postoperative adhesions from obstruction caused by bezoars. In addition, barium studies enable the detection of residual gastric bezoars. This information has important implications in patient treatment because bezoar obstruction is unlikely to respond to conservative treatment, and concurrent gastric bezoars must be removed to prevent recurrent bowel obstruction.
