Percutaneous endoscopic gastrostomy is commonly utilized in patients with head and neck cancer. Tumor at the PEG exit site is a rare occurrence, likely due to direct implantation. We present a case report, review of the relevant literature, discussion of the mechanism of spread, and management.

Perforation of the esophagus is a well-described complication of pneumatic dilatation in patients with achalasia. Although successful management of these patients without surgical intervention has been reported, little follow-up data exist. We report the successful nonsurgical management of esophageal perforation after pneumatic dilatation in three patients. Manometric and radionuclide esophageal emptying studies in these patients showed satisfactory results after the dilatations despite the occurrence of perforation, and the excellent symptomatic response has been maintained during a follow-up period ranging from one to four years.

The CT appearance of gastrointestinal involvement in Henoch-Schonlein syndrome is described. The protean manifestations of this disorder are easily confused both clinically and radiographically with those of many other conditions. Mural thickening, thickened folds, ulceration, and spasm are seen radiographically. The CT appearance of segmental mural thickening and luminal narrowing correlates well with the abnormalities seen on the small-bowel series and upper endoscopy.
