Inflammatory Bowel Disease V: Surgical Management

298
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

294
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...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

121
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Area of Science:

  • Bariatric Surgery Outcomes
  • Cardiovascular Physiology

Background:

  • Orthostatic intolerance (OI) is a potential complication following bariatric surgery (BS).
  • The predisposing factors for new-onset OI post-BS remain largely unknown.
  • Understanding these factors is crucial for patient management and improving outcomes.

Purpose of the Study:

  • To systematically review and summarize existing data on new-onset orthostatic intolerance after bariatric surgery.
  • To identify potential predisposing factors and associated comorbidities.

Main Methods:

  • A systematic literature search was conducted up to July 30, 2020.
  • Studies were screened and selected based on predefined eligibility criteria.
  • Data extraction followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Main Results:

  • Four studies met the inclusion criteria, involving predominantly female patients (83.3%).
  • Commonly reported comorbidities included hypertension, type 2 diabetes mellitus, and obstructive sleep apnea syndrome.
  • Information on surgical revisions, conversions, or reversals was not documented in the included studies.

Conclusions:

  • New-onset orthostatic intolerance following bariatric surgery is an emerging concern.
  • Hypertension, type 2 diabetes, and obstructive sleep apnea are frequently associated comorbidities.
  • Increased awareness is necessary to mitigate risks of syncope and reduced quality of life.
