Intraluminal pressure measurements during barium enema: full column vs. air contrast.

Intraluminal pressure measurements were made during enema examination of 10 patients undergoing full column studies and 10 patients receiving air-contrast studies. There was no significant difference between the pressure in the distal colon of the two groups. All pressures were less than those produced by Valsalva maneuver or straight leg raising, and were generally less than those previously found to be necessary to rupture the colon. The authors believe that the findings should dispel any fear that an air-contrast examination is more hazardous than a full column study. Perforations occurring during these procedures are more likely related to disease of the colon wall or local trauma.

Granular cell myoblastoma of the esophagus. Report of two cases.

Granular cell myoblastoma (GCM) of the esophagus is a rare, usually benign tumor, most often discovered incidentally during upper endoscopy, surgery, or autopsy. Although some reports have questioned the safety of endoscopic biopsy of granular cell tumors of the esophagus, we feel that the procedure can be performed safely and accurately. For the unwary, histological examination may lead to a misdiagnosis of squamous cell carcinoma. Although some reports of malignant esophageal tumors can be found, in general, if the histologic appearance of the tumor is benign, malignant transformation or metastasis is unusual. Surgical resection for malignant and for large symptomatic benign tumors is the treatment of choice. In, however, individuals with histologically benign tumors. who are asymptomatic or who are not considered good surgical candidates, careful observation with endoscopic follow-up can be safely done.
