Bone tissue exhibits self-healing properties; however, not all defects can be repaired without surgical intervention. Bone tissue engineering offers artificial scaffolds, which can act as a temporary matrix for bone regeneration. The aim of this study was to manufacture scaffolds made of poly(lactic acid), poly(ε-caprolactone), poly(propylene fumarate), and poly(ethylene glycol) modified with bioglass, beta tricalcium phosphate (TCP), and/or wollastonite (W) particles.

The ageing population and bone diseases are the main causes of the growing need for novel treatments offered by bone tissue engineering. Three-dimensional (3D) scaffolds, as artificial structures that fulfil certain characteristics, can be used as a temporary matrix for bone regeneration.

Methods: This is a retrospective cohort study from the 2015 sample of the National Health Interview Survey database utilizing univariate and multivariate regression analysis. The study population includes subjects between 50 and 75 years of age.
Background: The National Accreditation Program for Rectal Cancer recommends a pelvic MRI to assess the response to neoadjuvant therapy for advanced rectal cancers. However, there is no single restaging modality that can identify all patients with complete tumor response. At our institution, we perform both a pelvic MRI and a flexible sigmoidoscopy (FS) after neoadjuvant therapy prior to surgical resection.

With the wide implementation of enhanced recovery after surgery (ERAS) protocols in colorectal patients, the predictive power of frailty and its contribution to morbidity and length of stay (LOS) can be underestimated.
Methods: We reviewed all colectomy patients undergoing ERAS protocol at a single, tertiary care institution from January 2016-January 2019.
Background: Newly created ileostomies often result in patient readmission due to dehydration secondary to high ostomy output. Implementation of a mandatory home intravenous hydration protocol can avoid this. We aim to evaluate the impact of mandatory home intravenous hydration for patients with newly created ileostomies.
View Article and Find Full Text PDFPurpose: Enhanced Recovery After Surgery (ERAS) protocols, particularly when paired with advanced laparoscopy, have reduced recovery time following colorectal procedures. The aim of this study was to determine if length of stay (LOS) could be reduced to an overnight observation stay (< 24 h) with comparable perioperative morbidity. The secondary aim was to establish predictive factors contributing to early discharge.

Robot-assisted laparoscopy has been developed to overcome some of the important limitations of conventional laparoscopy. The new system is designed to assist surgeons in performing minimal access surgery and overcome some of the challenges associated with currently available surgical robots.

These patients frequently suffer from other concomitant pathologies like rectocele, sigmoidocele, cystocele, or even enterocele. Rectopexy with a mesh has been an established treatment for rectal prolapse.

This study examines the predictive power of the five-item modified frailty index (5-mFI) in predicting outcomes in colorectal surgery patients.
Methods: The American College of Surgeons National Surgical Quality Improvement Program Database was queried from 2011 to 2016 to determine the predictive power of 5-mFI in patients who had colorectal surgery.
Achievement of pathologic complete response (pCR) in patients with locally advanced rectal cancer correlates with improved prognosis relative to non-pCR counterparts. Such correlations are not well established in the context of a community-based hospital. This study aims to examine pCR rates, recurrences, and survival data for locally advanced rectal cancer patients in community settings.

Objective: The purpose of this article is to present manufacturing details accompanied by evidence of construct, face, and content validity for a robotic rectal dissection simulation.
Perianal Paget's disease (PPD) is an extremely rare condition characterized as intraepithelial adenocarcinoma of unclear etiology. It can be either primary or secondary. The disease typically presents as an eczema-like, erythematous, and painful skin lesion that is associated with pruritus.

Methods: From 2005 to 2012, 101 consecutive rectal cancers operated robotically were enrolled in a prospective database. Patients were stratified into obese (BMI ≥ 30 kg/m2) and non-obese (BMI < 30 kg/m2) groups.
Background: Sphincter-sparing repairs are commonly used to treat anal fistulas with significant muscle involvement.
Objective: The current study evaluates the trends and efficacy of sphincter-sparing repairs and determines risk factors for fistula recurrence.
Design And Settings: A retrospective review was performed at 3 university-affiliated teaching hospitals.
