What is the effect of percutaneous cholesistostomy in patients with acute cholecystitis? when is the right time for the procedure?

Background: Acute cholecystitis (AC) is one of the most common emergency diseases in surgical practice. Although the gold standard treatment is laparoscopic cholecystectomy, percutaneous cholecystostomy (PC) is performed in some patients due to age, comorbidity, and delays in admission. We aimed to investigate the effect of timing on the clinical process of patients undergoing PC.

Impact of positive-to-total lymph node ratio on prognosis in stage 3 colorectal cancer. A multicenter study.

Background: Colorectal cancer remains a health problem despite advances in diagnostic and treatment methods. This study aimed to determine the impact of positive-to-total lymph node ratio on survival in colorectal cancer.

Methods: Patients with stage 3 colorectal cancer were included.

Effect of tumor size on prognosis in colorectal cancer.

Aim: This study aimed to reveal the effect of tumor size on overall survival and disease-free survival.

Material And Methods: This study retrospectively evaluated the data of 593 patients who underwent colorectal surgery for colorectal cancer (CRC) between May 2012 and December 2018. The patients were divided into two groups based on their tumor size; those with a tumor size <5 cm were grouped as group 1 and those with a tumor size ≥ 5 cm were grouped as group 2.

Analysis of upper gastrointestinal endoscopy results during the Covid-19 pandemic. A high-volume single-Center experience.

Purpose: The histopathological effects of the COVID-19 period on the upper gastrointestinal system are not clearly known. This study is the first in the literature to compare the results of upper endoscopic biopsy before and during the COVID- 19 period.

Methods: Data of 10510 patients who underwent upper endoscopy with a given biopsy sample during the procedure between March 2019 and March 2021 were retrospectively scanned.

Thyroid Hormone Changes After Sleeve Gastrectomy With and Without Antral Preservation.

Background: The effect of bariatric surgery on thyroid hormone changes yielded inconsistent results. The aim of the present study was to assess the change of thyroid hormone levels following laparoscopic sleeve gastrectomy (LSG), with or without antral preservation (AP).

Methods: Thyroid hormones (TSH, FT3, FT4) were examined preoperatively, at the end of the first postoperative month, and first postoperative year.

The Importance of Rockall Scoring System for Upper Gastrointestinal Bleeding in Long-Term Follow-Up.

The aim of the study is to examine the importance of Rockall scoring system in long-term setting to estimate re-bleeding and mortality rate due to upper gastrointestinal bleeding. A total of 321 patients who had been treated for upper gastrointestinal bleeding were recruited to the study. Patients' demographic and clinical data, the amount of blood transfusion, endoscopy results, and Rockall scores were retrieved from patients' charts.

Diffusion Weighted MR Imaging of Breast and Correlation of Prognostic Factors in Breast Cancer.

Background: Through Diffusion Weighted Imaging (DWI), information related to early molecular changes, changes in the permeability of cell membranes, and early morphologic and physiologic changes such as cell swelling can be obtained.

Aims: We investigated the correlation between the prognostic factors of breast cancer and apparent diffusion coefficient (ADC) in DWI sequences of malignant lesions.

Study Design: Retrospective cross-sectional study.

Two Etiological Reasons of Constipation: Anterior Rectocele and Internal Mucosal Intussusception.

Chronic constipation is a common problem in the general population. Rome III criteria can be used for the diagnosis of chronic constipation. The aim of this study is to emphasize the importance of anterior rectocele and mucosal intussusception as two etiological factors for chronic constipation.
