Clinical Context

Low anterior resection syndrome (LARS) affects up to 80% of patients following sphincter-preserving rectal cancer surgery. The LARS score provides a validated patient-reported outcome measure for bowel dysfunction, enabling systematic assessment and targeted management of incontinence, frequency, and urgency.

Colorectal cancer staging follows the AJCC TNM 8th Edition system, with additional prognostic information provided by the MSKCC recurrence nomogram and molecular markers including MSI status, BRAF, and RAS mutations. These tools guide adjuvant chemotherapy decisions.

The Hinchey classification remains the standard for diverticulitis severity assessment, guiding decisions between medical management, percutaneous drainage, and surgical intervention. Functional assessment with the Wexner fecal incontinence score quantifies symptom severity and treatment response.

About

Colorectal Surgery

Colorectal surgical practice relies on functional assessment tools like the LARS and Wexner scores, as well as evidence-based staging and recurrence nomograms. We provide a centralized location for managing colorectal cancer and benign anorectal conditions.

Covered Areas

  • LARS & Functional Bowel Assessment
  • Colorectal Cancer Staging & Prognosis
  • Diverticulitis Classification
  • Anorectal Function Scoring
  • Surgical Risk (POSSUM)
  • Stoma Outcomes Assessment

All tools are based on published clinical evidence. Results should be interpreted alongside individual patient presentation and current institutional guidelines.
