METHODS: Online databases including PubMed, Embase, Cochrane Library, and Web of Science were searched from inception to December 5, 2022, for eligible studies about evaluating the efficacy of platelet-rich plasma (PRP) in treating anal fistula. Literature search, screening, data extraction, and quality assessment were carried out by two independent investigators...

PURPOSE: Colonoscopy is the gold standard for the diagnosis of colorectal cancer (CRC). Before a colonoscopy, an adequate bowel preparation (BP) is required. Currently, more novel regimens with different effects have been proposed and used successively. This network meta-analysis aims to compare the cleaning effects and patients' tolerability of several BP regimens. METHODS: We performed a network meta-analysis of randomized controlled trials including sixteen kinds of BP regimens...

PURPOSE: Patients undergoing laparoscopic colorectal cancer resection have a high incidence of postoperative gastrointestinal dysfunction (POGD). Remote ischemic preconditioning (RIPC) is an organ protection measure. The study investigated the effect of RIPC on postoperative gastrointestinal function. METHODS: In this single-center, prospective, double-blinded, randomized, parallel-controlled trial, 100 patients undergoing elective laparoscopic colorectal cancer resection were randomly assigned in a 1:1 ratio to receive RIPC or sham RIPC (control)...

INTRODUCTION AND OBJECTIVES: Indocyanine green (ICG) was introduced as a promising diagnostic tool to provide real-time assessment of intestinal vascularization. Nevertheless, it remains unclear whether ICG could reduce the rate of postoperative AL. The objective of this study is to assess its usefulness and to determine in which patients is most useful and would benefit the most from the use of ICG for intraoperative assessment of colon perfusion. METHODS: A retrospective cohort study was conducted in a single center, including all patients who underwent colorectal surgery with intestinal anastomosis between January 2017 and December 2020...

PURPOSE: This study aimed to investigate the prognostic effect of tumor deposits (TDs) in lymph node negative rectal cancer. METHODS: Patients who had undergone surgery for rectal cancer with curative intention between 2011 and 2014 were extracted from the Swedish Colorectal Cancer Registry. Patients with positive lymph nodes, undisclosed TD status, stage IV disease, non-radical resections, or any outcome (local recurrence (LR), distant metastasis (DM) or mortality) within 90 days after surgery were excluded...

PURPOSE: To systematically reevaluate the role of psychological factors in functional gastrointestinal disorders (FGIDs) and thus provide a scientific basis for the psychological treatment of FGIDs. METHODS: A literature search was conducted using the PubMed, Embase, Web of Science, and Cochrane Library databases from January 2018 to August 2022 for researches on psychological factors affecting patients with functional gastrointestinal disorders. Meta-analysis was carried out with Stata17...

PURPOSE: To identify 5-year survival prognostic variables in patients with colorectal cancer (CRC) and to propose a survival prognostic score that also takes into account changes over time in the patient's health-related quality of life (HRQoL) status. METHODS: Prospective observational cohort study of CRC patients. We collected data from their diagnosis, intervention, and at 1, 2, 3, and 5 years following the index intervention, also collecting HRQoL data using the EuroQol-5D-5L (EQ-5D-5L), European Organization for Research and Treatment of Cancer's Quality of Life Questionnaire-Core 30 (EORTC-QLQ-C30), and Hospital Anxiety and Depression Scale (HADS) questionnaires...

BACKGROUND: Melanosis coli is characterized by brown mucosa with pigmentation. Studies have showed an increased adenoma detection rate in melanosis patients, whether it is caused by a contrast effect or an oncogenic effect is still controversial. The detection of serrated polys in melanosis patients remains unknown. AIMS: The study aimed to clarify the correlation of adenoma detection rate with melanosis coli and discuss outcomes in less-experienced endoscopists...
