To push or to pull? A clinical audit on the efficacy and safety of the pull and push percutaneous endoscopic gastrostomy techniques in oncological patients.

Background: The peroral "pull" technique and the direct "push" procedure are the two main methods for percutaneous endoscopic gastrostomy (PEG) placement. Although pull-PEG is generally recommended as the first-line modality, many oncological patients require a push-PEG approach to prevent tumor seeding or overcome tumor-related obstruction.

Objective: We aimed to compare the efficacy and safety of both PEG procedures in cancer patients.

Effect of Colonoscopy Screening on Risks of Colorectal Cancer and Related Death.

Background: Although colonoscopy is widely used as a screening test to detect colorectal cancer, its effect on the risks of colorectal cancer and related death is unclear.

Methods: We performed a pragmatic, randomized trial involving presumptively healthy men and women 55 to 64 years of age drawn from population registries in Poland, Norway, Sweden, and the Netherlands between 2009 and 2014. The participants were randomly assigned in a 1:2 ratio either to receive an invitation to undergo a single screening colonoscopy (the invited group) or to receive no invitation or screening (the usual-care group).

Comparison of Quality Measures for Detection of Neoplasia at Screening Colonoscopy.

Background & Aims: The proportion of colonoscopies with at least one adenoma (adenoma detection rate [ADR]) is inversely associated with colorectal cancer (CRC) risk and death. The aim of this study was to examine whether such associations exist for colonoscopy quality measures other than ADR.

Methods: We used data from the Polish Colorectal Cancer Screening Program collected in 2000-2011.

Watch-and-wait strategy in rectal cancer: Is there a tumour size limit? Results from two pooled prospective studies.

Background: Frequency and predictive factors for a clinical complete response (cCR) in unselected patients are unclear.

Material And Methods: Two prospective observational studies were designed and pooled to explore predictive factors for cCR. Both studies evaluated the watch-and-wait strategy in consecutive patients; the first single-institutional study in elderly with a small tumour, the second multi-institutional study in all the patients receiving standard of care preoperative radiotherapy.

Cost-effectiveness of colonoscopy in an organized screening program.

Introduction: Colorectal cancer (CRC) is a serious health problem, and various screening programs to reduce CRC have been introduced worldwide. However, the cost‑effectiveness of a program based on once‑in‑a‑lifetime colonoscopy in Poland is unknown.

Objectives: The main aim of this study was to assess the cost‑effectiveness of Polish Colonoscopy Screening Platform (PCSP), the colonoscopy screening program in Poland.
