ABSTRACT
Objective To investigate the pathogen and inspection methods of the middle-aged women with constipation and evaluate the accuracy and clinical application of imaging to constipation.Methods First colonic transit test were used to 98 cases of middle-aged women who were diagnosed constipation by doctors,then air-barium double contrast examination were applied.Defecation radiography or simulation rectum defecography were used to those who were diagnosed as outlet obstruction.According to the measure target and diagnostic criteria of professor LU,the results were studied.Results 6 cases were abnormal within 8 cases who were inspected by barium enema.14cases were abnormal within 16 cases who were inspected by defecation radiography.Colonic transit test were used to 74 cases and only 6 cases were normal.16 cases were true slow transmission and 20 cases were false slow transmission.52 cases were outlet obstruction.20 volunteers were inspected by suspension barium sulfate and simulation rectum defecography.Conclusions Air-bariun double contrast examination could discover the organic disease and abnormal of rectum.colonic transit test,defecation radiography and simulation rectum defecography were simply and perfect methods to discover the pathogen of constipation.
ABSTRACT
Objective To study the clinical significance for the establishment of diagnosis of small bowel obstruction by selective small bowel enterography through a nasointestinal decompression tube. Methods Tirty-five patients with small bowel obstruction, with no strangulation or other contraindications, were intubated with a 300 cm nasointestinal decompression tube till upper jejunum under X-ray monitoring. The patients firstly underwent intra-small-intestinal suction therapy. When the tube reached the diseased region, a selective small bowel enterography was performed. Under X-ray inspection, 20-100 ml of 76% meglumine diatrizoatis and 50-200 ml of air were slowly injected via the decompression tube to perform double contrast intestinal radiography. Results Intubation was successful in all the 35 patients. Mter the small intestinal decompression therapy. Obstruction was cured in 20 cases, alleviated in 15 cases, and 10 cases received operation. Small bowel enterography in this series was all of high quality, there were 6 cases in which no abnormal X-ray findings, adhesive small bowel obstruction was suggested in 15 cases, small bowel tumor was identified in 4 cases (3 metastatic tumor, 1 small bowel cancer), small bowel Crohn's disease in 3 cases, radioactive enteritis in 3 cases, enteric intussusception in 2, polyp of the small intestine in one, and carcinoma of the ascending colon in one. Conclusions The nasointestinal decompression intubation with X-ray monitoring serves a dual function for the patients with intestinal obstruction, it decompresses the small bowel and does small intestinal radiography, in this way the locale of obstruction was found and the cause of the obstruction identified.
ABSTRACT
Objective To investigate the relations between radiological findings and pathological classification of superficial depressed(Ⅱc type)early gastric cancer.Methods Radiological features in subtonic double contrast barium examination and the endoscopic pictures of early gastric cancer compared with the global pathological specimens and micro-pathological features were prospectively studied.Combined with the gastric endoscopic pictures,the sharpness of margin of the lesions,the changes of converging mucosal folds and the changes of the depressed surface on the film of double contrast barium examination were analyzed.The correlation between the radiological features and histological classification of gastric cancer including well differentiated tubular adenocarcinoma(tub1),moderately differentiated tubular adenocarcinoma(tub2),poorly differentiated adenocarcinoma(por)and signet-ring cell carcinoma(sig) were studied.Results In 102 cases of Ⅱc type early gastric cancer,there were tubl 27 cases,tub2 11, por 26 and sig 38 cases histologically.The margin of the depressed lesions of tub1(24 cases)and tub2 (9 cases)cancers were mostly unsharply demarcated or with fine spicular border,while the margin of lesions of por(15 cases)and sig(31 cases)were mostly clearly and sharply demarcated,with statistical significance (P
