For the detec-tion of carcinoma of the large bowelthis method cannot be substituted forthe barium enema, but in determiningthe extent of infiltration of such a carci-noma the method is of the greatest ad-vantage. In a carcinoma of the de-scending colon the process was showninfiltrating the lateral abdominal walland extending into the retroperitonealtissues, involving the kidney above andextending well into the pelvis will be seen from this brief resume.

Note theappearance of the transverse and descending portions of the stomach. that pneumoperitoneum examination ofthe gastro-intestinal tract, at least atthe present state of development oftechnique, cannot be used as a substi-tute for barium meal examination; thatit is especially applicable to certainlesions of the stomach most difficult todetect by barium meal examination,notably lesions of the anterior and pos-terior stomach wall; that it is practicallythe best method of examination to de-termine the contents of hernial sacs andadhesions of the intestines and stomachto each other and the abdominal wall,either post-opeartive or otherwise; thatwith a somewhat wider experience itmay prove of great advantage in sub-acute or chronic appendicitis; thatwhile it is not the best method of dem-onstrating carcinoma of the large bowelit is of great advantage in determiningthe extent of infiltration and the organsinvolved.
