We herein present 2 cases of adult Bochdalek hernia. Only a total of 51 such cases have been reported since 1958, and we have reviewed these cases and discussed their clinical features, operative treatment and final outcome. The majority of these patients presented as acute surgical emergencies and a lack of awareness of this condition lead to an incorrect diagnosis in 38 per cent. Intestinal obstruction with left lung signs and a non-distended abdomen in an adult patient should arouse suspicion of this condition. A plain X-ray of the chest and contrast studies of the gastrointestinal tract are necessary to confirm the diagnosis. A previous normal chest X-ray does not rule out a diaphragmatic hernia, as the defect may be plugged by the spleen or by the presence of a confining sac. The high incidence of strangulation emphasises the need for early diagnosis and prompt operative management which gives highly satisfactory results.
A study was carried out in the patients with intestinal tuberculosis and obstruction requiring surgery to determine the pathogenesis of malabsorption in this condition. Fifteen of the 20 patients studied had malabsorption, nine of 17 (53%) had intestinal bacterial overgrowth and 10 of 16 (62.6%) had free bile acids in their jejunal aspirates. In a comparable group of nontuberculus intestinal obstruction requiring surgery, six of seven (85.7%) had malabsorption, and four of five (80%) had both the bacterial overgrowth as well as bile salt deconjugation. Among a group of 10 patients with intestinal tuberculosis without significant obstruction, four were found to have malabsorption but only one had evidence of bacterial overgrowth and bile salt deconjugation. In contrast, only one of the 10 patients with extraintestinal tuberculosis and none of the 12 healthy, normal subjects had malabsorption. None had bacterial overgrowth or bile salt deconjugation in either group. Resection of the obstructing lesion corrected the malabsorption as well as the bacterial overgrowth and the bile salt deconjugation in all four patients tested with intestinal tuberculosis. Malabsorption in intestinal tuberculosis thus appears to be associated with obstruction rather than with the tuberculous process. Demonstration of bacterial overgrowth and bile salt deconjugation in the upper small intestine of patients with intestinal tuberculosis with obstruction and malabsorption indicate the presence of a stagnant loop syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
