The sigmoid colon in Zambians
Medical Journal of Zambia
|February 1, 1980
Summary
This study measured sigmoid colon variables in Zambians, finding inconclusive results for the etiology of sigmoid volvulus. Anatomical measurements did not clarify the cause of this common gastrointestinal condition.
Area of Science:
- Gastroenterology
- Human Anatomy
- Public Health
Background:
- Sigmoid volvulus is a common cause of large bowel obstruction, particularly in certain populations.
- The exact etiology of sigmoid volvulus remains incompletely understood.
- Understanding anatomical variations may offer insights into predisposition.
Purpose of the Study:
- To investigate anatomical characteristics of the sigmoid colon in a Zambian population.
- To explore potential correlations between sigmoid colon morphology and the incidence of sigmoid volvulus.
- To identify factors that may contribute to the high prevalence of sigmoid volvulus in Zambia.
Main Methods:
- A cross-sectional study involving 103 Zambian adults (73 males).
- Measurement of key sigmoid colon variables: length, mesentery height, mesentery attachment length, and mesentery thickness.
- Data analysis focused on mean values across sexes.
Main Results:
- Mean sigmoid colon length: 32.9cm (men) and 29.5cm (women).
- Mean mesentery height: 8.2cm (both sexes).
- Mean mesentery attachment length: 10.3cm (men) and 10.8cm (women).
- Mean mesentery thickness: 3.0mm (both sexes).
Conclusions:
- The measured anatomical variables of the sigmoid colon in Zambians were inconclusive.
- The findings did not elucidate the etiology or contributing factors of sigmoid volvulus.
- Further research is needed to understand the underlying causes of sigmoid volvulus in this demographic.

01:23Anatomy of the Intestines
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...

01:27Histology of the Small Intestine
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

01:09Large 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...

01:25Endoscopic 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:
01:26Endoscopic 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...

01:27Diverticular 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...
