Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

931
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

Sarcopenia, a loss of muscle mass, predicted mortality in emergency surgery patients during initial analysis but not in multivariate models. This measure is a convenient tool for preoperative risk assessment.

Area of Science:

  • Gerontology
  • Surgical Outcomes
  • Radiology

Background:

  • Sarcopenia, age-related muscle mass loss, is a frailty indicator.
  • It predicts outcomes in surgical patients, including cancer and elderly cohorts.
  • This study investigates sarcopenia's predictive value in emergent laparotomy.

Purpose of the Study:

  • To determine if sarcopenia, measured by preoperative CT scans, predicts mortality and morbidity in emergent laparotomy patients.
  • To assess the utility of total psoas area (TPA) as a predictor of surgical outcomes.

Main Methods:

  • Utilized data from the American College of Surgeons National Surgical Quality Improvement Program (2008-2013).
  • Included adult patients undergoing open emergency abdominal surgery with preoperative CT scans.
  • Calculated total psoas area (TPA) from CT scans, normalized by height, and analyzed its association with postoperative outcomes.

Main Results:

  • Of 781 surgeries, 593 had adequate CT scans.
  • Univariate analysis showed TPA significantly associated with morbidity, length of stay, and 90-d mortality.
  • Multivariate analysis indicated TPA lost significance compared to predictors like ASA classification.

Conclusions:

  • Sarcopenia (TPA) significantly predicted mortality in univariate analysis but not multivariate.
  • TPA is a readily available, low-risk tool for preoperative risk assessment.
  • Incorporating TPA may enhance preoperative patient evaluation and counseling.
