Pneumoperitoneum, or free air in the peritoneal cavity, typically indicates visceral organ perforation requiring urgent surgical intervention. In peritoneal dialysis (PD) patients, however, it can occur without prior surgery or trauma, often due to technical errors, and may mimic peritonitis, risking misdiagnosis and unnecessary treatment. We report a case of a 73-year-old male PD patient presenting with fever, abdominal pain, and bowel ileus, initially raising concerns for organ perforation due to pneumoperitoneum.

Perioperative infections as a prognostic risk factor in hepatocellular carcinoma and cholangiocellular carcinoma: a comparative analysis.

World J Surg Oncol

January 2025

Department for General, Visceral and Pediatric Surgery, Medical Faculty, Heinrich Heine University Düsseldorf, University Hospital Düsseldorf, Düsseldorf, Germany.

Background: Hepatocellular Carcinoma (HCC) and cholangiocellular adenocarcinoma (CCA) are the most common primary liver tumors representing a major global health burden. In early disease stages, tumor resection may provide long-term survival in selected patients. However, morbidity and mortality rates are still relatively high after extended liver surgery with perioperative bacterial infections representing major complications.

Background: Neuroendocrine liver metastases (NELM) significantly reduce survival in patients with neuroendocrine tumor. The management of NELM is challenged by a low rate of resectability and a high rate of recurrence. Indocyanine green (ICG) fluorescence imaging offers potential advantages in real-time tumor visualization and margin assessment.

Deep Learning Reconstruction for Enhanced Resolution and Image Quality in Breath-Hold MRCP: A Preliminary Study.

J Comput Assist Tomogr

November 2024

From the Department of Diagnostic Radiology, Graduate School of Medical Sciences, Kumamoto University, Kumamoto, Japan.

Objective: This preliminary study aims to assess the image quality of enhanced-resolution deep learning reconstruction (ER-DLR) in magnetic resonance cholangiopancreatography (MRCP) and compare it with non-ER-DLR MRCP images.

Methods: Our retrospective study incorporated 34 patients diagnosed with biliary and pancreatic disorders. We obtained MRCP images using a single breath-hold MRCP on a 3T MRI system.

The traditional method of performing open common bile duct exploration (OCBDE) was replaced by a less invasive procedure known as laparoscopic common bile duct exploration (LCBDE) in elective surgery. But at present, the application of this technique is considered novel and controversial to treat acute cholangitis (AC). The aim of our systematic review was to investigate the safety and efficacy of laparoscopic surgery in patients with AC.
