Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

132
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 II: Colonoscopy

151
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Cardiomyopathy VII: Pre and Post Operative Nursing Management

16
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...

Assessment of the Rectum and Anus

300
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Cancer Survival Analysis01:21

Cancer Survival Analysis

403
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Factors Influencing Drug Absorption: Disease States and Pharmacology

599
Multiple disease states can significantly influence the oral drug absorption process by affecting blood flow and the functionality of the gastrointestinal (GI) system. Various GI diseases, including conditions that alter GI motility, such as diarrhea, decreased acid secretions (achlorhydria), and infections, have been associated with reduced drug absorption.
Substances such as alcohol and specific drugs, including antineoplastics, can also negatively impact drug absorption. For instance,...

Area of Science:

  • Oncology
  • Surgical Oncology
  • Clinical Research

Background:

  • Colorectal cancer (CRC) surgery carries a risk of inpatient mortality.
  • Identifying predictive factors for mortality is crucial for improving patient outcomes.

Purpose of the Study:

  • To identify factors associated with inpatient mortality in patients undergoing colorectal cancer (CRC) resection.
  • To evaluate the impact of pre-existing conditions and perioperative events on CRC surgical outcomes.

Main Methods:

  • A case-control study design was employed, comparing 35 deceased patients with 105 survivors of CRC resection.
  • Multivariate analysis using LASSO penalized regression identified significant predictors.
  • Data were collected from a tertiary care institution between 2004 and 2018.

Main Results:

  • Patients who died were older and had higher comorbidity scores (Charlson Comorbidity Index).
  • Preoperative anemia, hypoalbuminemia, emergency surgery, and postoperative ICU admission were more frequent in non-survivors.
  • Anemia (aOR=8.62), emergency admission (aOR=5.71), and ICU admission (aOR=45.51) were significant predictors of inpatient mortality.

Conclusions:

  • Pre-existing anemia and perioperative factors, such as emergency surgery and ICU admission, are strong predictors of inpatient mortality after CRC resection.
  • These factors appear more influential than baseline comorbidity or nutritional status in predicting CRC surgical mortality.
