Emergency colorectal surgery has high rates of complications and mortality because of incomplete bowel preparation and bacterial contamination. The authors aimed to evaluate the surgical outcomes and the risk factors for the mortality and the complication rates of patients who underwent emergency surgery to treat colorectal diseases.
This is a prospective study from January 2014 to April 2016, and the results are based on a retrospective analysis of the clinical results for patients who underwent emergency colorectal surgery at Chosun University Hospital.
A total of 99 patients underwent emergency colorectal surgery during the study period. The most frequent indication of surgery was perforation (75.8%). The causes of disease were colorectal cancer (19.2%), complicated diverticulitis (21.2%), and ischemia (27.2%). There were 27 mortalities (27.3%). The major morbidity was 39.5%. Preoperative hypotension and perioperative blood transfusion were independent risk factors for both morbidity and mortality.
These results revealed that emergency colorectal surgeries are associated with significant morbidity and mortality. Furthermore, the independent risk factors for both morbidity and mortality in such patiients were preoperative hypotension and perioperative transfusion.

The aim of this study is to investigate the impact of age on short-term outcomes after colorectal surgery in terms of the 30-day postoperative morbidity and mortality rates.
The subjects for the study were patients who had undergone colorectal surgery. Patients were divided into 2 groups according to age; groups A and B patients were ≥80 and <80 years old of age, respectively. Both groups were manually matched for body mass index, American Society of Anesthesiologists score, Charlson Comorbidity Index and procedure performed.
A total of 200 patients, 91 men (45.5%) and 109 women (54.5%), were included in this retrospective study. These patients were equally divided into 2 groups. The mean ages were 85 years in group A (range, 80 to 104 years) and 55.3 years in group B (range, 13 to 79 years). The overall 30-day postoperative mortality rate was 1% of total 200 patients; both of these 2 patients were in group A. However, this observation had no statistical significance. No intraoperative complications were encountered in either group. The overall 30-day postoperative morbidity rate was 27% (54 of 200) for both groups. The 30-day postoperative morbidity rates in groups A and B were 28% (28 of 100) and 26% (26 of 100), respectively. However, these differences between the groups had no statistical significance importance.
Age alone should not be considered to be more of a contraindication or a worse predictor than other factors for the outcome after colorectal surgery on elderly patients.

The purpose of this study is to compare postoperative complications for single-stage surgery after mechanical bowel preparation in patients who experienced obstruction and those who did not.
From 2000 to 2011, 1,224 patients underwent a single-stage operation for left colorectal cancer after bowel preparation. Nonobstruction (NOB) and obstruction (OB) colorectal cancer patients were 1,053 (86.0%) and 171 (14.0%), respectively. Postoperative morbidity and mortality were compared between groups.
The OB group had poor preoperative conditions (age, white blood cell, hemoglobin, albumin level, and advanced tumor stage) compared with the NOB group (P < 0.05). Mean on-table lavage time for the OB group was 17.5 minutes (range, 14-60 minutes). Mean operation time for the OB group was statistically longer than that of the NOB group (OB: 210 minutes; range, 120-480 minutes vs. NOB: 180 minutes; range, 60-420 minutes; P < 0.001). Overall morbidity was similar between groups (NOB: 19.7% vs. OB: 23.4%, P = 0.259). Major morbidity was more common in the OB group than in the NOB group, but the difference was without significance (OB: 11.7% vs. NOB: 7.6%, P = 0.070). Postoperative death occurred in 16 patients (1.3%), and death in the OB group (n = 7) was significantly higher than it was in the NOB group (n = 9) (4.1% vs. 0.9%, P = 0.001). Twelve patients had surgical complications, which were the leading cause of postoperative death: postoperative bleeding in five patients and leakage in seven patients.
Postoperative morbidity for a single-stage operation for obstructive left colorectal cancer is comparable to that for NOB, regardless of poor conditions of the patient.

The aim of this study is to assess the effects of age on the short-term outcomes of a laparoscopic resection of colorectal cancer in elderly (≥75 years old), as compared with younger (<75 years old), patients.
A retrospective analysis of patients who underwent laparoscopic surgery for colorectal cancer between January 2007 and December 2009 was performed. There were two groups: age <75 years old (group A) and age ≥75 years old (group B). The perioperative outcomes between group A and group B were compared.
The study included 824 patients in group A and 92 patients in group B. The body mass index (BMI) and the American Society of Anesthesiologists (ASA) score were significantly different between group B and group A (BMI: 22.5 vs. 23.5, P = 0.002; ASA score: 1.88 vs. 1.48, P = 0.001). Mean operating times were similar between the groups (325.4 minutes vs. 351.6 minutes, P = 0.07). We observed a higher overall complication rate in group B than in group A (12.0% vs. 6.2%, P = 0.047), but the number of severe complications of Accordion Severity Classification ≥3 (those that required an invasive procedure) was not significantly different between the two groups (6.5% vs. 3.4%, P = 0.142). There was no significant difference in the length of hospital stay (13.0 days vs. 12.0 days, P = 0.053).
Although the elderly patients had a significantly higher overall postoperative complication rate, no significant difference was seen in either the number of severe complications of Accordion Severity Classification ≥3 or in the length of hospital stay. A laparoscopic colorectal cancer resection in elderly patients, especially those aged 75 years or older, is safe and feasible.
