Gastrointestinal Surgical Patient and Multidisciplinary Healthcare Provider Beliefs and Practices Around Perioperative Nutrition: A Mixed-Methods Study.

Introduction: Nutrition is critical to gastrointestinal (GI) disease prevention and treatment, including operations, yet perioperative nutrition practices vary widely. We aimed to understand GI surgical patient and health care provider's perioperative nutrition beliefs and practices.

Materials And Methods: We used a mixed-methods approach, including a patient survey (n = 19), provider survey (n = 26), and semistructured interviews with a subset of providers (n = 15).

Society for Surgery of the Alimentary Tract State-of-the-Art Session 2022: Frailty in Surgery.

Given the exponentially aging population and rising life expectancy in the United States, surgeons are facing a challenging frail population who may require surgery but may not qualify based on their general fitness. There is an urgent need for greater awareness of the importance of frailty measurement and the implementation of universal assessment of frail patients into clinical practice. Pairing risk stratification with stringent protocols for prehabilitation and minimally invasive surgery and appropriate enhanced recovery protocols could optimize and condition frail patients before, during, and immediately after surgery to mitigate postoperative complications and consequences on patient function and quality of life.

Comparing three-dimensional endorectal ultrasound and magnification chromoendoscopy for early rectal neoplasia invasion depth assessment.

Introduction: Accurate assessment of invasion depth of early rectal neoplasms is essential for optimal therapy. We aimed to compare three-dimensional endorectal ultrasound (3D-ERUS) with magnification chromoendoscopy (MCE) regarding their accuracy in assessing parietal invasion depth (T).

Methods: Patients with middle and distal rectum neoplasms were prospectively included.

Impact of a Routine Colorectal Endoscopic Submucosal Dissection in the Surgical Management of Nonmalignant Colorectal Lesions Treated in a Referral Cancer Center.

Background: Recent data show an increasing number of abdominal surgeries being performed for the treatment of nonmalignant colorectal polyps in the West but in settings in which colorectal endoscopic submucosal dissection is not routinely performed. This study evaluated the number of nonmalignant colorectal lesions referred to surgical treatment in a tertiary cancer center that incorporated magnification chromoendoscopy and endoscopic submucosal dissection as part of the standard management of complex colorectal polyps.

Objective: The study aimed to estimate the number of patients with nonmalignant colorectal lesions referred to surgical resection at our institution after the standardization of routine endoscopic submucosal dissection and to describe outcomes for patients undergoing colorectal endoscopic submucosal dissection.

Is It Really Gone? Assessing Response to Neoadjuvant Therapy in Rectal Cancer.

Purpose: Non-operative management of rectal cancer is a feasible and appealing treatment option for patients who develop a complete response after neoadjuvant therapy. However, identifying patients who are complete responders is often a challenge. This review aims to present and discuss current evidence and recommendations regarding the assessment of treatment response in rectal cancer.

High-risk human papillomavirus test in anal smears: can it optimize the screening for anal cancer?

Objective: The current method for screening anal cancer is anal cytology, which has low sensitivity. Since high-risk human papillomavirus (HR-HPV) is associated with almost 90% of cases of anal cancer, the objective of this study is to evaluate whether testing for HR-HPV can optimize the screening.

Design: Prospective study with patients enrolled in a screening program for anal dysplasia.

Long-term outcomes of endoscopic submucosal dissection and transanal endoscopic microsurgery for the treatment of rectal tumors.

Background And Aim: Endoscopic submucosal dissection and transanal endoscopic microsurgery are good options for the treatment of rectal adenomas and early rectal carcinomas, but whether long-term outcomes of these procedures are comparable is not known. The aim of this study was to address this question.

Methods: A retrospective single-center study evaluating 98 consecutive procedures between June 2008 and December 2017 was performed in a tertiary cancer center.

EVALUATION OF LYMPHATIC SPREAD, VISCERAL METASTASIS AND TUMORAL LOCAL INVASION IN ESOPHAGEAL CARCINOMAS.

Background: Knowing esophageal tumors behavior in relationship to lymph node involvement, distant metastases and local tumor invasion is of paramount importance for the best esophageal tumors management.

Aim: To describe lymph node involvement, distant metastases, and local tumor invasion in esophageal carcinoma, according to tumor topography and histology.

Methods: A total of 444 patients with esophageal squamous cell carcinoma and 105 adenocarcinoma were retrospectively analyzed.

PROGNOSTIC FACTORS AND SURVIVAL ANALYSIS IN ESOPHAGEAL CARCINOMA.

Background: Despite recent advances in diagnosis and treatment, esophageal cancer still has high mortality. Prognostic factors associated with patient and with disease itself are multiple and poorly explored.

Aim: Assess prognostic variables in esophageal cancer patients.

ESOPHAGEAL CARCINOMA: IS SQUAMOUS CELL CARCINOMA DIFFERENT DISEASE COMPARED TO ADENOCARCINOMA? A transversal study in a quaternary high volume hospital in Brazil.

Background: Esophageal cancer is one of the leading causes of mortality among the neoplasms that affect the gastrointestinal tract. There are several factors that contribute for development of an epidemiological esophageal cancer profile in a population.

Objective: This study aims to describe both clinically and epidemiologically the population of patients with diagnosis of esophageal cancer treated in a quaternary attention institute for cancer from January, 2009 to December, 2011, in Sao Paulo, Brazil.
