Non-exposed endoscopic wall-inversion surgery with one-step nucleic acid amplification for early gastrointestinal tumors: Personal experience and literature review.

Background: Laparoscopic and endoscopic cooperative surgery is a safe, organ-sparing surgery that achieves full-thickness resection with adequate margins. Recent studies have demonstrated the safety and efficacy of these procedures. However, these techniques are limited by the exposure of the tumor and mucosa to the peritoneal cavity, which could lead to viable cancer cell seeding and the spillage of gastric juice or enteric liquids into the peritoneal cavity.

Quality of bowel cleansing in hospitalized patients undergoing colonoscopy: A multicentre prospective regional study.

Background: Quality of bowel cleansing in hospitalized patients undergoing colonoscopy is often unsatisfactory. No study has investigated the inpatient or outpatient setting as cause of inadequate cleansing.

Aims: To assess degree of bowel cleansing in inpatients and outpatients and to identify possible predictors of poor bowel preparation in the two populations.

Prevalence and incidence of cryoglobulins in hepatitis C virus-related chronic hepatitis patients: a prospective study.

Objective: A high prevalence of cryoglobulins has been reported in patients with hepatitis C virus (HCV)-related liver disease. The aim of this study was to evaluate the prevalence and the incidence of cryoglobulins and their association with clinical symptoms in chronic hepatitis and cirrhosis patients.

Methods: The prevalence of cryoglobulins and cryoglobulinemic syndrome was investigated at enrollment in 237 patients (213 with chronic hepatitis and 24 with cirrhosis).
