Summary
Double-balloon colonoscopy (DBc) is effective and safe for completing colon inspections after incomplete colonoscopies. It is preferred over computed tomography colonography (CTC) when pathology is likely.
Area of Science:
- Gastroenterology
- Endoscopy
- Colorectal Cancer Screening
Background:
- The Dutch national screening program has increased colonoscopy rates.
- Incomplete colonoscopies necessitate alternative diagnostic methods.
- Computed tomography colonography (CTC) and double-balloon colonoscopy (DBc) are options for incomplete procedures.
Purpose of the Study:
- Evaluate cecal intubation and pathology detection rates for DBc after incomplete colonoscopy.
- Assess complication rates of DBc.
- Analyze CTC findings in cases of incomplete colonoscopy.
Main Methods:
- Retrospective observational study.
- Analysis of DBc and CTC reports from a tertiary referral hospital.
- Inclusion of cases with initially incomplete colonoscopies.
Main Results:
- DBc achieved a 95% cecal intubation rate with 58% pathology detection (including 5% carcinoma).
- CTC preceded 54% of DBcs; 62% of CTC findings were confirmed.
- DBc involved biopsies in 16% and interventions in 60%; one major complication (1.5%) occurred.
Conclusions:
- DBc is an effective and safe method for completing colon inspections.
- DBc is recommended over CTC for patients with a high suspicion of colorectal pathology.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

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:

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...
