Objective:
To evaluate risk factors associated with morbidity and mortality in patients undergoing surgery for obstructing colorectal cancer.
Methods:
One hundred and eleven patients who underwent emergency surgery for obstructing colorectal cancer from January 2001 to December 2009 were retrospectively reviewed.
Results:
Forty-nine patients had obstruction proximal to the splenic flexure and 62 patients at or distal to the splenic flexure. The morbidity and mortality rates of the emergency surgery for malignant obstruction were 21.6% and 5.4%, respectively. Twenty-three patients received resection with primary anastomosis with intraoperative lavage for left-sided lesions. There was no difference in morbidity between right-sided cancer and left-sided cancer(P>0.05). Univariable analysis showed that complications rate was higher in patients with higher ASA score (3-4) and in those aged over 60 years. Multivariate logistic regression analysis revealed that ASA score(3-4) was an independent risk factor.
Conclusions:
Emergency surgery for obstructing colorectal cancer is associated with high rates of morbidity and mortality. Selection of the proper operation and intensive treatment after surgery are recommended in high risk patients.

Here are some common surgical interventions for IBD:
Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
