Comparison of Emergency Surgeries for Obstructed Colonic Cancer With Elective Surgeries; A Retrospective Study

Abstract

Objective:Colon cancer patients presented with obstruction were known to have worse postoperative morbidity and mortality rates, but conflicting data has been reported in recent years. We aimed to investigate postoperative complication rates, and short and long-term oncological outcomes in patients with colon cancer treated with either emergency surgery due to obstruction or elective surgery.Methods:Two hundred fifty two patients were analyzed. Patients presented with obstruction and underwent an emergency surgery, and patients operated under elective circumstances were compared according to their demographic variables, tumor characteristics, and short and long term treatment outcomes.Results:Distribution of age, gender and comorbidities were similar between both the groups. Need for an end colostomy was significantly higher in obstructed patients (22.7% vs 1.6%, respectively). Obstructed patients were tending to be at an advanced stage. Postoperative morbidity and mortality, and prognosis of colon cancer patients presented with obstruction is worse than patients operated under elective circumstances.Conclusions:Colon cancer patients presented with obstruction constitutes more than one quarter of all patients. These patients have significantly higher morbidity and mortality rates. Obstructed colon cancer usually appears at advanced stage. Primary resection and anastomosis is safe in most of the cases.

Comparison of short-term surgical outcomes and long-term survival between emergency and elective surgery for colorectal cancer: a systematic review and meta-analysis

“…Among these studies, 6 reports did not provide available data for pooled analysis, 4 were review articles, 4 were irrelevant to the current topic, and 3 studies included an overlapping patient population. Ultimately, we identi ed 28 relevant studies for the nal qualitative or quantitative analysis [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][22][23][24][25][26][27][28][29][30][31][32][33][34].…”

Determinants of emergency presentation in patients with colorectal cancer: a systematic review and meta-analysis

“…11 studies 13 , 15 , 20 , 22 , 24 , 27 – 29 , 38 , 43 , 44 examined the association between T Stage and mode of presentation in 40,130 patients (Supplementary Table S4 ). On meta-analysis including all of these studies (Fig.…”

“…29 studies 5 , 14 , 15 , 17 – 20 , 24 , 25 , 27 , 29 , 30 , 32 – 37 , 39 – 41 , 43 , 44 , 46 – 48 , 51 – 53 examined the association between age and mode of presentation in 909,131 patients (Supplementary Table S18 ). Due to heterogeneity of data it was not possible to perform a meta-analysis of this factor.…”
