Serum Laboratory Studies, Stool Test, Breath Test

325
Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

63
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

331
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

The COVID-19 pandemic delayed colorectal cancer (CRC) diagnosis and treatment, with patients showing hesitation to seek care. However, CRC prognosis remained unchanged, indicating resilience in patient outcomes despite pandemic challenges.

Area of Science:

  • Oncology
  • Public Health
  • Epidemiology

Background:

  • The COVID-19 pandemic significantly disrupted healthcare systems globally.
  • Colorectal cancer (CRC) screening and treatment pathways may have been affected, potentially impacting patient outcomes.

Purpose of the Study:

  • To evaluate the impact of the COVID-19 pandemic on the diagnosis, treatment, and patient/practitioner behavior related to colorectal cancer (CRC).

Main Methods:

  • A retrospective analysis compared CRC patients undergoing surgery between pre-pandemic (April 2019-March 2020) and pandemic (April 2020-March 2021) periods.
  • Clinical presentation and time from symptom onset to presentation were analyzed.

Main Results:

  • Fewer positive fecal occult blood tests were observed during the pandemic (13.5% vs. 25.0%).
  • Symptomatic patients experienced significantly longer delays from symptom onset to presentation (115 vs. 31 days).
  • Preoperative sub-obstruction rates increased during the pandemic (41.4% vs. 23.4%), with no changes in cancer stage or survival.

    • Conclusions:

    • Patient hesitation to seek CRC examination and treatment increased during the COVID-19 pandemic.
    • Despite diagnostic and treatment delays, the overall prognosis for colorectal cancer patients did not change.
