Summary
Postoperative ileus (POI) affects 13% of patients after colorectal cancer surgery. Independent risk factors include higher BMI, prior abdominal surgery, adhesions, and opioid use, highlighting surgeon-modifiable elements.
Area of Science:
- Colorectal Surgery
- Surgical Oncology
- Gastroenterology
Background:
- Postoperative ileus (POI) is a frequent complication following colorectal cancer surgery.
- Identifying risk factors is crucial for improving patient outcomes and reducing healthcare costs.
Purpose of the Study:
- To determine the incidence of postoperative ileus (POI) after colorectal cancer surgery.
- To identify independent risk factors associated with the development of POI.
Main Methods:
- A cohort of 300 consecutive patients undergoing colorectal cancer surgery was analyzed.
- Postoperative ileus was defined as absent intestinal function for ≥72 hours, confirmed radiographically.
- Univariate and multivariate logistic regression analyses were performed to identify risk factors.
Main Results:
- The incidence of POI was 13% (39 patients).
- Univariate analysis revealed several associated factors including age, gender, BMI, alcohol consumption, opioid use, prior abdominal surgery, adhesions, multivisceral resection, blood loss, and open approach.
- Multivariate analysis identified independent risk factors: BMI ≥26 kg/m², opioid use, history of abdominal operation, and adhesions.
Conclusions:
- Postoperative ileus is a significant complication in colorectal surgery.
- Surgeon-dependent factors such as open surgical approach and postoperative opioid administration appear to contribute to POI.
- Further research into mitigating these modifiable risk factors is warranted.

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
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...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

857
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Introduction
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...

01:25Assessment of the Rectum and Anus
1.5K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:17Irritable Bowel Syndrome I: Introduction
1.2K
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
