Large Intestine

Large Intestine

The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

Inflammatory Bowel Disease V: Surgical Management

Inflammatory Bowel Disease V: Surgical Management

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:

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Endoscopic Procedures II: Colonoscopy

Endoscopic Procedures II: Colonoscopy

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:

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

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...

Diverticular Disease of the Colon

Diverticular Disease of the Colon

Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...

Summary

The ileocolonic junction plays a minor role in solid content transit through the gut. Even after right hemicolectomy, the remaining colon effectively stores residue, maintaining normal bowel habits.

Area of Science:

Gastroenterology
Surgical Oncology
Colorectal Surgery

Background:

The ileocolonic junction's role in gut transit is not fully understood.
Right hemicolectomy for colon cancer impacts gastrointestinal anatomy.

Purpose of the Study:

To evaluate the function of the human ileocolonic junction in solid content transit.
To assess the impact of right hemicolectomy on gastrointestinal transit and residue storage.

Main Methods:

Scintigraphic transit study using radiolabeled beads after a mixed meal.
Comparison between eight patients post-hemicolectomy and eight healthy controls.

Main Results:

Gastric emptying was initially faster in the postoperative group, but overall transit and small bowel transit did not differ.
Solid content transit from the small to large bowel was similar in patients without an ileocolonic junction and controls.
The remaining colon (transverse and descending) stored residue, though less than in controls.

Conclusions:

The ileocolonic sphincter plays a minimal role in human ileocolonic transit.
The colon retains significant residue storage capacity after right hemicolectomy, preserving bowel habits.
