Evaluation of a progressive algorithmic approach for the treatment of unresectable colon polyps using colon conservation techniques.

Background: The majority of endoscopically unresectable colon polyps (EUCP) are treated by segmental colectomy. However, up to 90% of EUCP do not harbor malignancy, making colectomy an unnecessary procedure. To minimize unnecessary segmental colectomy, we established a progressive treatment algorithm utilizing colon conservation techniques (CCT).

Adjuvant Chemotherapy Does Not Improve Recurrence-Free Survival in Patients With Stage 2 or Stage 3 Rectal Cancer After Neoadjuvant Chemoradiotherapy and Total Mesorectal Excision.

Background: Current guidelines for locally advanced stage 2/3 rectal cancer recommend neoadjuvant chemoradiotherapy followed by total mesorectal excision and adjuvant chemotherapy. The oncologic benefit of adjuvant chemotherapy has not been consistently demonstrated.

Objective: The purpose of this study was to evaluate disease recurrence and survival in patients with rectal cancer who received adjuvant chemotherapy after chemoradiotherapy and total mesorectal excision.

Carnoy's solution fixation with compression significantly increases the number of lymph nodes yielded from colorectal cancer specimens.

Background And Objectives: Carnoy's fixation and compression represents a novel technique to enhance lymph node evaluation and accuracy of staging after colorectal cancer resection.

Methods: This study was performed in all adults undergoing colorectal cancer operations by Kaiser Permanente surgeons at two separate facilities. Patients were assigned to either location based upon surgeon and patient availability.

Robotic Transanal Minimally Invasive Surgery for the Excision of Rectal Neoplasia: Clinical Experience With 58 Consecutive Patients.

Background: Given the significant perioperative risks and costs of total mesorectal excision, minimally invasive transanal surgical approaches have grown in popularity for early rectal cancer and rectal polyps. This article discusses a transanal robotic surgery technique to perform full-thickness resections of benign and malignant rectal neoplasms.

Objective: The purpose of this study was to describe an initial experience with robotic transanal minimally invasive surgery.

Expectant management surveillance for patients at risk for invasive squamous cell carcinoma of the anus: a large US healthcare system experience.

Purpose: To determine the impact of expectant management surveillance for patients at risk for squamous cell carcinoma of the anus (SCCA).

Methods: Adult patients at risk for anal cancer, specifically those with human immunodeficiency virus (HIV) or known human papilloma virus (HPV) infections (anal dysplasia, anogenital warts, cervical dysplasia, or cervical cancer), underwent expectant management surveillance with targeted therapy of only grossly abnormal or symptomatic anoderm lesions. A retrospective analysis investigated the SCCA incidence in these surveilled populations and in the general population patients without known HIV or HPV infection.

Recurrence of Rectal Prolapse After Surgical Repair in Women With Pelvic Organ Prolapse.

Background: Pelvic organ prolapse is prevalent among women with rectal prolapse.

Objective: This study aimed to determine whether clinically significant pelvic organ prolapse impacts rectal prolapse recurrence after surgical repair.

Design: A retrospective cohort.

Value of gastrografin in adhesive small bowel obstruction.

Background: Small bowel obstruction (SBO) from adhesive disease presents great burden for the healthcare system. Some groups have reported water soluble contrast agents (WSCA) protocols, but published studies are underpowered. This study introduces a WSCA protocol to improve outcomes and streamline patient care.
