“…Sloan, Briggs, and Halsted (1951) report one case of intestinal perforation, Tulin, Kern, and Almy (1952) three cases, Pessel, Beairsto, Edwards, Rathmell, and Wise (1953) one case, all in ulcerative colitis. Levin, Rivo, Scott, Figueroa, Fred, and Barrett (1953) describe a case of perforation in rheumatoid arthritis with widespread arteritis; Sauer, Dearing, and Wollaeger (1953) one case in ulcerative colitis and two in regional enteritis; Bradley (1954) one case of rheumatoid arthritis without arteritis; Palmer, Mason, and Adams (1955) two cases of diverticulitis; and Gumpel, Lewis, and Thomson (1957) one case of ulcerative colitis. In the present paper three cases of intestinal perforation are described-one case with perforations in the jejunum and duodenum, one case in the caecum, and another in the sigmoid colon.…”
