A retrospective analysis was carried out on 56 pts., (37 M, 19 F), mean age 64 yrs., operated for moderate to severe obstruction due to left colon carcinoma.

Abstract
A retrospective analysis was carried out on 56 pts., (37 M, 19 F), mean age 64 yrs., operated for moderate to severe obstruction due to left colon carcinoma. Clinical and pathological features, treatment and results were compared with those of 108 pts. with left colon cancer who underwent elective surgery. Mean duration of obstructive symptoms was 5.3 days and mean delay between admission and operation was 1.15 days. Site and nature of the obstruction were assessed pre-operatively in 80.3% of the pts. Distribution of tumor localization was similar in the two groups. ASA risk was statistically higher in pts. with obstruction. Staging according to the Astler-Coller (mod. 1978) classification, showed a greater incidence of more advanced stages in the obstructing tumors. In the group with obstruction a three stage surgery was carried out in 18 pts. (32.1%), a two stage in 6 (10.7%), a primary resection in 6 (10.7%) and a decompressive colostomy in 26 (46.5%). Radicality and resectability rates were 50% and 53.6% vs 69.4% and 82.4% in elective surgery. Mean post-operative stay was 42 and 21 days respectively in the two groups. Overall post-operative death rate was 19.6% vs 9.2%, and 3.3% vs 7.8% after resective surgery. Post-operative complications accounted for 21.4% vs 21.3%. 5-year survival rate after curative surgery was 47.8% vs 76.8%. On the basis of their results and on Literature reports the Authors suggest a reevaluation of a staged surgical treatment for obstructing left colon cancer based on primary decompression following an E.L. when needed. Consequent resection and intestinal reconstruction should be performed after 2-3 weeks.(ABSTRACT TRUNCATED AT 250 WORDS)
