    Abstract:
    BACKGROUND: Lithotomy (LT) and prone jackknife positions (PJ) are routinely used for abdominoperineal resection (APR). The present study compared the clinical, pathological, and oncological outcomes of PJ-APR vs. LT-APR in low rectal cancer patients in order to confirm which position will provide more benefits to patients undergoing APR. METHODS: This is a retrospective study of consecutive patients with low rectal cancer who underwent curative APR between January 2002 and December 2011. Patients were matched 1:2 (PJ-APR = 74 and LT-APR = 37 patients) based on gender and age. Perioperative data, postoperative outcomes, and survival were compared between the two approaches. RESULTS: Hospital stay was shorter with PJ-APR compared with LT-APR (P < 0.05). Compared with LT-APR, duration of anesthesia (234 ± 50.8 vs. 291 ± 69 min, P = 0.022) and surgery (183 ± 44.8 vs. 234 ± 60 min, P = 0.016) was shorter with PJ-APR, and estimated blood losses were smaller (549 ± 218 vs. 674 ± 350 mL, P < 0.001). Blood transfusions were required in 37.8% of LT-APR patients and in 8.1% of PJ-APR patients (P < 0.001). There was no difference in the distribution of N stages (P = 0.27). Median follow-up was 47.1 (13.6-129.7) months. Postoperative complications were reported by fewer patients after PJ-APR compared with LT-APR (14.9% vs. 32.4%, P = 0.030). There were no significant differences in overall survival, disease-free survival, local recurrence, and distant metastasis (P > 0.05). CONCLUSIONS: The PJ position provided a better exposure for low rectal cancer and had a lower operative risk and complication rates than LT-APR. However, there was no difference in rectal cancer prognosis between the two approaches. PJ-APR might be a better choice for patients with low rectal cancer.
