| Objective: To investigate the clinical features and electronic computed Tomography (CT) imaging features of acute appendicitis in soldiers who have been living in plateau for a long time. Methods: The clinical features and imaging data of 56 cases of acute appendicitis in soldiers who have been living in plateau for a long time confirmed by surgery from February 2022 to August 2024 were retrospectively analyzed. Results: In 56 cases with acute appendicitis in soldiers who have been living in plateau for a long time, the appendectomy position results showed: anterior ileum 4 cases (7.14%), lower ileum 10 cases (17.86%), posterior cecum 16 cases (28.57%), lower cecum 9 cases (16.07%), lateral cecum 2 cases (3.58%), posterior ileum 6 cases (10.71%), high (subhepatic) 9 cases (16.07%), and left lower abdominal 0 cases, retroperitoneal appendicitis 0 cases, which was suggested that the anatomical position variation of appendicitis in soldiers with acute appendicitis who have been living at high altitude for a long time was relatively large. The direct manifestations of multi-slice spiral CT showed: appendectomy enlarged diameter >6mm in 49 cases (87.50%), appendicular wall thickening >2mm in 42 cases (75.00%), ppendiceal dilation lumen and effusion in 29 cases (51.79%), appendix indistinctness in 3 cases (5.36%), 1ppendix fecalith: 27 cases (48.21%), gas in the appendix in 16 cases (28.57%) .Indirect findings of multi-slice spiral CT showed that, periappendiceal exudation with shadow in 32 cases (57.14%) , appendiceal cellulitis with peripheral abscess in 9 cases (16.07%), peritonitis and ascites in 13 cases (23.21%), ileocecal intestinal wall thickening in 22 cases (39.29%), mesenteric lymph node enlargement in 16 cases (28.57%), reflexive intestinal stasis in ileocecal region was observed in 19 cases (33.93%). Conclusion: In the officers and soldiers with acute appendicitis who lived at high altitude for a long time, multi-slice spiral CT showed the direct manifestations of appendiceal thickening, tube wall thickening, lumen dilatation, fluid accumulation, etc., and the indirect manifestations were periappendiceal exudation with shadow, appendiceal cellulitis with peripheral abscess, ileocecal intestinal wall thickening, reflexes of small intestine and mesenteric lymph node enlargement. Multi-slice spiral CT has the advantages of clear and intuitive, high safety, high resolution and simple operation in the diagnosis of acute appendicitis. |
