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.

Endoscopic Procedures III: Video Capsule Endoscopy

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...

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...

Summary

This summary is machine-generated.

Endoscopic cyclophotocoagulation can lead to phthisis, a severe complication causing vision loss and hypotony. This case highlights the risks associated with the procedure for managing elevated intraocular pressure.

Area of Science:

Ophthalmology
Surgical Innovation

Background:

Elevated intraocular pressure (IOP) requires effective management to prevent vision loss.
Endoscopic cyclophotocoagulation (ECP) is a surgical option for refractory glaucoma.
ECP targets ciliary processes to reduce aqueous humor production.

Observation:

A 47-year-old male presented with uncontrolled IOP.
The patient underwent 360-degree ECP of the ciliary processes.
Pretreatment visual acuity was 4/200 with IOP of 24 mm Hg.

Findings:

Post-ECP, the patient experienced significant ocular inflammation and pain.
Phthisical changes developed 5 months postoperatively, with visual acuity declining to 1/200 and IOP to 7 mm Hg.
At 18 months, visual acuity was light perception and IOP was less than 1 mm Hg.

Implications:

Phthisis bulbi is a potential, severe complication of ECP.
Careful patient selection and monitoring are crucial after ECP.
This case underscores the need to weigh the risks and benefits of ECP in managing IOP.
