To examine the potential correlation between the coagulation indicators and the severity of the strangulated intestinal obstruction, the patients in the strangulated group were further divided into 2 subgroups: ischemia subgroup and necrosis subgroup, and the values of WBC, NEUT, platelet count, CRP, PT, APTT, Fib, TT, and D-D were compared. The gene discussed is FBL; the disease is intestinal obstruction.
