Summary
This study establishes normal 3D anorectal manometry (3DARM) values for primigravid mothers, providing essential reference data for assessing anal sphincter function during pregnancy and postpartum.
Area of Science:
- Obstetrics and Gynecology
- Pelvic Floor Disorders
- Anorectal Physiology
Background:
- Vaginal delivery poses a risk for anal sphincter injury.
- Antepartum reference values are needed to identify postpartum injury.
- Normal 3D manometry values are currently unavailable for pregnant women.
Purpose of the Study:
- To determine and describe the normal 3D manometry values in primigravid women.
- To establish a baseline for postpartum anal sphincter assessment.
Main Methods:
- Analysis of 3D Anorectal Manometry (3DARM) data from 101 primigravid mothers in their third trimester.
- Utilized the Given Imaging ManoScan system for data acquisition.
Main Results:
- Established mean resting pressure (RP) of 87.02 mmHg and maximum squeeze pressure (SP) of 179.21 mmHg.
- Determined mean high-pressure zone (HPZ) length of 3.67 cm and sensory volumes.
- Observed pressure asymmetry highest in the lower anal sphincter.
Conclusions:
- Normal 3DARM values for Sri Lankan primigravid mothers were successfully established.
- These values serve as crucial reference points for future research and clinical practice.

01:25Assessment of the Rectum and Anus
1.9K
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.

01:19Urodynamic Studies: Uroflowmetry
7.9K
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

01:26Muscles of the Pelvic Floor and Perineum
6.0K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

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...

01:23Assessment of the Abdomen III: Palpation
5.1K
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...
