Background:Severe anemia caused by hemorrhoidal hematochezia is typically treated preoperatively with reference to severe anemia treatment strategies from other etiologies.This retrospective cohort study included 128 patients with hemorrhoidal severe anemia admitted to 3 hospitals from September 1, 2018, to August 1, 2023, and aimed to evaluate preoperative blood transfusion requirements. Material/Methods:Of 5120 patients with hemorrhoids, 128 (2.25%; male/female: 72/56) experienced hemorrhoidal severe anemia, transfusion, and Milligan-Morgan surgery.Patients were categorized into 2 groups based on their preoperative hemoglobin (PHB) levels after transfusion: PHB ³70 g/L as the liberal-transfusion group (LG), and PHB <70 as the restrictive-threshold group (RG).The general condition, bleeding duration, hemoglobin level on admission, transfusion volume, length of stay, immune transfusion reaction, surgical duration, and hospitalization cost were compared between the 2 groups. Results:Patients with severe anemia (age: 41.07±14.76)tended to be younger than those with common hemorrhoids (age: 49.431±15.59years).The LG had a significantly higher transfusion volume (4.77±2.22units), frequency of immune transfusion reactions (1.22±0.58),and hospitalization costs (16.69±3.31thousand yuan) than the RG, which had a transfusion volume of 3.77±2.09units, frequency of immune transfusion reactions of 0.44±0.51,and hospitalization costs of 15.00±3.06thousand yuan.Surgical duration in the LG (25.69±14.71min) was significantly lower than that of the RG (35.24±18.72 min). Conclusions:Patients with hemorrhoids with severe anemia might require a lower preoperative transfusion threshold than the currently recognized threshold, with an undifferentiated treatment effect and additional benefits.
