Effectiveness and safety of 1-L PEG-ASC versus other bowel preparations for colonoscopy: A meta-analysis of nine randomized clinical trials.

BACKGROUND AND AIMS: A 1-L polyethylene glycol plus ascorbate (PEG-ASC) preparation has been recently developed to improve patients' experience in colonoscopy. This meta-analysis aimed to evaluate the effectiveness and safety of 1-L PEG-ASC compared with those of other bowel preparations for colonoscopy. METHODS: MEDLINE, Embase, Scopus, and the Cochrane Library were systematically searched for randomized controlled trials comparing 1-L PEG-ASC with other bowel preparations published through July 2022. A random-effects model was applied for pooling the results; heterogeneity was expressed as I2. RESULTS: Nine studies met the inclusion criteria and were included. The analysis showed significantly higher cleansing success (CS) (OR = 1.50; 95% CI = 1.25-1.81; p < 0.01, I2 = 0%) and right-colon high-quality cleansing (HQC) (OR = 1.67; 95% CI = 1.21-2.31; p < 0.01, I2 = 43%) with 1-L PEG-ASC compared to the other preparations. The pooled estimate of the adenoma detection rate (ADR) did not significantly differ between the two groups either in the overall (OR = 1.02; 95% CI = 0.87-1.20; p = 0.79, I2 = 0%) or split-dosing regimen subgroup analysis (OR = 0.99; 95% CI = 0.84-1.18; p = 0.94, I2 = 0%). A significantly higher pooled estimate of the number of patients with adverse events (AEs) (OR = 1.51; 95% CI = 1.23-1.84; p<0.01, I2 = 0%) and incidence of AEs (IRR=1.33; 95% CI = 1.11-1.58; p<0.01, I2 = 71%) was observed with 1-L PEG-ASC than with the other preparations. No serious AEs or deaths occurred. CONCLUSIONS: Compared to other preparations, 1-L PEG-ASC yielded higher overall CS, higher right-colon HQC rates, and similar ADR. The number of patients with AEs and incidence of the total AEs were significantly higher with 1-L PEG-ASC in the absence of serious AEs.

Concomitant Heterotopic Pancreas and Endometriosis as a Rare Cause of Ileo-Ileal Intussusception in a Young Woman with Spina Bifida: Case Report and Literature Review.

INTRODUCTION: Isolated heterotopic pancreas (HP) as the primary cause of bowel intussusception is extremely rare. We report a case of a 33-year-old female patient with spina bifida admitted to the Emergency Surgical Department for ileal intussusception due to the presence of heterotopic pancreas associated with endometriosis. AREAS COVERED: Symptomatic ileal intussusception for ectopic pancreas is usually associated with overt gastrointestinal blood loss (predominantly melena), abdominal pain, vomiting, and weight loss. Treatment is universally surgical. EXPERT COMMENTARY: Isolated heterotopic pancreas is a rare condition; it should be considered in the differential diagnosis of bowel intussusception.

[Introduction of Greek medicine to Rome: political and ideologic discord]. / L'introduction de la médecine grecque à Rome: une dissension politique et idéologique.

The opposition of Cato the Elder and other traditionalists to the introduction of Greek medicine in Rome by Archagathus was the result of several factors: political strife in the Roman nobility, hostility against Greek culture, fear of Archagathus' surgical and pharmaceutical treatments, and loathing for the mercenary character of the medical profession, which was regarded as a sign of luxury.
