Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

88
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...

Ostomy Care01:24

Ostomy Care

304
Introduction
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:

Suctioning the Nasopharyngeal Airway

427
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Area of Science:

  • Urology
  • Radiation Oncology
  • Medical Device Complications

Background:

  • SpaceOAR hydrogel is widely used in prostate cancer radiotherapy to minimize rectal toxicity.
  • Hydrogel spacers create a separation between the prostate and rectum during radiation treatment.
  • Minimizing rectal dose is critical for improving patient outcomes and reducing side effects.

Observation:

  • A 64-year-old male developed a perineal abscess post-SpaceOAR hydrogel insertion.
  • The patient presented with symptoms requiring clinical evaluation and intervention.
  • This highlights a rare but significant adverse event associated with the procedure.

Findings:

  • The case report details the clinical presentation and management of the perineal abscess.
  • It identifies the SpaceOAR hydrogel insertion as the preceding event.
  • The findings underscore the potential for serious complications despite the benefits of the hydrogel spacer.

Implications:

  • Vigilant post-insertion monitoring is essential for patients receiving SpaceOAR hydrogel.
  • Early recognition and prompt management of complications like abscesses are critical.
  • Adherence to proper insertion techniques and prophylactic measures may reduce complication risks.
