Summary
Transanal alcohol administration can cause chemical proctocolitis, a rare condition. This case report highlights a patient who recovered with conservative treatment, with no surgical intervention required for this alcohol-induced colitis.
Area of Science:
- Gastroenterology
- Toxicology
Background:
- Chemical proctocolitis is infrequently reported following transanal alcohol administration.
- This case highlights a rare instance of severe proctocolitis induced by a large volume of concentrated alcohol instilled rectally.
Purpose of the Study:
- To report a rare case of chemical proctocolitis induced by transanal alcohol administration.
- To discuss the clinical presentation, diagnostic findings, and management of alcohol-induced proctocolitis.
Main Methods:
- A case report of a 21-year-old male who self-administered 1.8 L of 35% alcohol transanally.
- Diagnostic evaluation included abdominal computed tomography (CT) and endoscopy.
- Treatment involved conservative management.
Main Results:
- The patient presented with melena and altered consciousness.
- Abdominal CT and endoscopic findings were consistent with ischemic colitis.
- The patient recovered with conservative treatment and was discharged after a 9-day hospital stay.
Conclusions:
- Alcohol-induced chemical proctocolitis is a rare but serious condition.
- Reported cases, including this one, have not required surgical intervention and resolved with conservative therapy.

Lower GI Series: Barium Enema
1.4K
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
12.7K
Overview
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Chemical Formulas
60.9K
A chemical formula presents information about the proportions of atoms constituting a particular chemical compound or molecule, mainly using symbols of elements and numbers. At times other symbols, such as dashes, parentheses, brackets, commas, plus, and minus signs, are also used. A chemical formula can be one of three types – molecular, empirical, and structural.

Protection of Alcohols
8.0K
This lesson delves into the concept of protection and deprotection of a functional group fundamental to synthetic organic chemistry. These phenomena are explained in the context of aliphatic and aromatic alcohols.
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
