| Popis: | Neoadjuvant radiation therapy (RT) downstages rectal cancer but may increase postoperative morbidity. This study aims to quantify 30-day complication rates after total mesorectal excision (TME) using current techniques and to assess for an association of these complications with neoadjuvant RT.Stage I-III rectal cancer patients who underwent TME from 2005 to 2010 were identified. Complications occurring within 30 days after TME were retrieved from a prospectively maintained institutional database of postoperative adverse events.The cohort consisted of 461 patients. Median age was 59 years (range 18-90), and 274 patients (59 %) were male. Comorbid conditions included obesity (n = 147; 32 %), coronary artery disease (n = 83; 18 %), diabetes (n = 65; 14 %), and inflammatory bowel disease (n = 19; 4 %). A low anterior resection (LAR) was performed in 383 cases (83 %), an abdominoperineal resection (APR) was performed in 72 cases (16 %), and a Hartmann's procedure was performed in 6 cases (1 %). Preoperative RT was delivered to 310 patients (67 %; median dose of 50.4 Gy, range 27-55.8 Gy). The 30-day incidence of postoperative mortality was 0.4 % (n = 2), any complication 25 % (n = 117), grade 3 or more complication 5 % (n = 24), intra-abdominal infection 3 % (n = 12), abdominal wound complication 9 % (n = 42), perineal wound complication after APR 11 % (n = 8/72), and anastomotic leak after LAR 2 % (n = 6/383). These events were not associated with neoadjuvant RT.In a cohort undergoing TME using current techniques, neoadjuvant RT was not associated with 30-day postoperative morbidity or mortality. |
