Purpose: To propose guidelines based on an expert-panel-derived unified approach to the technical performance, interpretation, and reporting of MRI for baseline and post-treatment staging of rectal carcinoma.
Methods: A consensus-based questionnaire adopted with permission and modified from the European Society of Gastrointestinal and Abdominal Radiologists was sent to a 17-member expert panel from the Rectal Cancer Disease-Focused Panel of the Society of Abdominal Radiology containing 268 question parts. Consensus on an answer was defined as ≥ 70% agreement. Answers not reaching consensus (< 70%) were noted.
Results: Consensus was reached for 87% of items from which recommendations regarding patient preparation, technical performance, pulse sequence acquisition, and criteria for MRI assessment at initial staging and restaging exams and for MRI reporting were constructed.
Conclusion: These expert consensus recommendations can be used as guidelines for primary and post-treatment staging of rectal cancer using MRI.

Background: Neoadjuvant chemoradiotherapy for rectal cancer improves surgical outcomes and reduces recurrence but can cause low anterior resection syndrome (LARS), affecting quality of life. This study aims to predict the risk of LARS in male patients with mid-low rectal cancer after laparoscopic total mesorectal excision (TME).
Methods: Clinical data from 203 male patients with mid-low rectal cancer who underwent neoadjuvant therapy and laparoscopic resection were collected.

Sexual and gender minorities (SGMs) experience critical barriers to health care access and have unique health care needs that are often overlooked. Given the rise in individuals identifying as lesbian, gay, bisexual, transgender, and queer, colorectal surgeons are likely to care for increasing numbers of such individuals. Here, we discuss key barriers to health care access and research among SGM populations and outline approaches to address these barriers in clinical practice.

This chapter explores the interplay between morbid obesity and the challenges encountered in colorectal surgery. Understanding the unique considerations in preoperative and intraoperative management along with weight optimization tools such as bariatric surgery emerges as potential mitigators, demonstrating benefits in reducing colorectal cancer risk and improving perioperative outcomes. Furthermore, the pervasive stigma associated with morbid obesity further complicates patient care, emphasizing the need for empathetic and nuanced approaches.

Patients with advanced colorectal cancer nearing the end of life require a multidisciplinary approach to address the unique challenges they face. Using a case vignette, we outline the various stages of a patient's journey with advanced rectal cancer and the common obstacles to their care as they interface with the medical system. We highlight how Black persons might be vulnerable to differences in screening, treatment, procedural interventions, end-of-life care, and health care decision-making.
