Introduction: Abdominosacral resection (ASR) usually required blood transfusions, which are virtually no longer in use in the modified abdominosacral amputation of the rectum (ASAR). The aim of this study was to compare the intra-operative bleeding in low-rectal patients subjected to ASR or ASAR.
Material and methods: The study included low-rectal cancer patients subjected to ASR (n = 114) or ASAR (n = 46) who were retrospectively compared in terms of: 1) the frequency of blood transfusions during surgery and up to 24 h thereafter; 2) the volume of intraoperative blood loss (ml of blood transfused) during surgery and up to 24 h thereafter; 3) hemoglobin concentrations (Hb) 1, 3 and 5 days after surgery; 4) the duration of hospitalization.
Results: Blood transfusions were necessary in 107 ASR patients but in none of those subjected to ASAR (p < 0.001). Median blood loss in the ASR group was 800 ml (range: 100–4500 ml). The differences between the groups in median Hb determined 1, 3 and 5 days following surgery were insignificant. The proportions of patients with abnormal values of Hb, however, were significantly higher in the ASR group on postoperative days 1 and 3 (day 1: 71.9% vs. 19.6% in the ASAR group, p = 0.025; day 3: 57.% vs. 13.0%, p = 0.009). Average postoperative hospitalization in ASR patients was 13 days compared to 9 days in the ASAR group (p = 0.031).
Conclusions: Abdominosacral amputation of the rectum predominates over ASR in terms of the prevention of intra- and postoperative bleeding due to the properly defined surgical plane in low-rectal cancer patients.
