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...

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Background:

Bladder neck dissection is challenging in patients with prior prostate surgery, such as transurethral prostate resection.
Radical perineal prostatectomy (RPP) requires precise dissection of the prostate-vesical junction.
Maintaining bladder neck integrity is crucial for post-prostatectomy continence.

Purpose of the Study:

To describe a modified endoscope-assisted RPP technique for improved bladder neck dissection.
To evaluate the safety and efficacy of this technique in patients with a history of transurethral prostate resection.
To assess oncologic outcomes and urinary continence after the procedure.

Main Methods:

A novel technique involving perurethral circumscription of the bladder neck with a Collins knife before RPP was employed.
The modified approach was used in four patients with prior transurethral prostate resection.
The remainder of the RPP was performed using the traditional approach.

Main Results:

The Collins knife facilitated precise identification and easier dissection of the prostate-vesical junction.
All four patients achieved organ-confined prostate cancer with negative surgical margins.
Continence was maintained in all patients during a 6-month follow-up period.

Conclusions:

The described endoscope-assisted technique simplifies bladder neck management during RPP in previously operated patients.
This modified approach offers precise dissection under direct vision, enhancing safety and potentially reducing invasiveness.
The technique appears to be a simple, less invasive, and oncologically safe option for managing the bladder neck perurethrally.
