Mitral Valve Prolapse I: Introduction

Mitral Valve Prolapse I: Introduction

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Mitral Valve Prolapse II: Assessment and Management

Mitral Valve Prolapse II: Assessment and Management

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular tachycardia.

Hiatal Hernia

Hiatal Hernia

A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or heavy...

Summary

The Yang-Monti modification offers an effective solution for bowel vaginoplasty in obese patients or those with android pelvises. This technique successfully created adequate neovaginal length and function without complications in a small patient cohort.

Area of Science:

Reconstructive surgery
Gynecologic surgery
Urology

Background:

Bowel vaginoplasty presents challenges in extremely obese patients or those with android pelvises.
The Yang-Monti principle is evaluated as an alternative surgical technique.

Purpose of the Study:

To assess the efficacy of the Yang-Monti principle in bowel vaginoplasty for challenging patient populations.

Main Methods:

Retrospective review of 4 patients (out of 60) who underwent Yang-Monti modified bowel vaginoplasty between 1980-2008.
Neovagina created using an 8-10 cm segment of detubularized and retubularized descending colon.
Outcomes assessed via physical examination and postoperative sexual function data.

Main Results:

Two patients had XY karyotype with android pelvis and prior failed surgeries; one had primary mullerian agenesis and was morbidly obese.
No intraoperative or postoperative complications were observed.
Median follow-up of 6 years (range 4-9) showed no stenosis, adequate vaginal length, and successful vaginal intercourse in two patients.

Conclusions:

The Yang-Monti modification is an effective adjunct to colovaginoplasty for selected patients.
This technique facilitates neovaginal lengthening without compromising the vascular pedicle.
