The aim of this study was to analyze the impact of contrast extravasation defined by computed tomography (CT) and angiography on massive transfusion and 30-day mortality in patients with acute bleeding undergoing transarterial embolization (TAE).

Prognostic relevance of CT-defined body composition in esophageal cancer patients undergoing curative treatment.

Introduction: Body composition including low skeletal muscle mass (LSMM) defined by skeletal muscle index (SMI) and subcutaneous and visceral adipose tissue (SAT and VAT) can be assessed using cross-sectional imaging techniques. Previous studies have shown promising prognostic value for several tumour entities, including esophageal cancer (EC). The aim of this study was to analyse possible associations of body composition parameters in patients with esophageal cancer undergoing curative treatment.

Laparoscopic hyperspectral imaging for in vivo detection of the vagal nerve in upper gastrointestinal surgery.

Background: Accurate intraoperative detection of nerves in critical anatomic regions during oncologic resection, such as the vagal nerve, is crucial. The vagal nerve regulates many internal organs and is at risk during surgeries, potentially leading to severe complications. While different types of intraoperative neuromonitoring methods exist for functional assessment, Hyperspectral Imaging (HSI) offers a non-invasive, real-time alternative for morphologic identification.

[Functional Outcome of Radiotherapy, Chemotherapy and Surgery in the Treatment of Rectal Cancer].

Treatment of rectal cancer is multimodal and based on tumour stage and location, as well as morphological and biological risk factors - using surgery, radiotherapy, and chemotherapy. In a large number of cases, there are several treatment options, some of which can cause similar and some of which can cause different functional limitations. Comparisons of functional outcomes between different treatment modalities are currently limited.

Drug dissolution problems in ostomy patients: a chart review and patient interview analysis.

Purpose: The pharmacokinetic properties of peroral drugs, e.g. considering dissolution, release and absorption, can be influenced by a shortened transit time after ostomy placement.

Patient-specific 3D-tissue slices from peritoneal metastases - An model for individual susceptibility analysis.

Objectives: The prognosis of patients with peritoneal metastases (PM) is poor, and these patients have a brief overall survival. Most patients with advanced PM receive palliative therapy to maintain their quality of life. In our current study, we investigated whether patient-specific 3D-tissue slices from patients with PM subjected to pressurized intraperitoneal aerosol chemotherapy could be cultured .

Pregnancy in Patients with Inflammatory Bowel Disease: A Narrative Review.

Background: The incidence of inflammatory bowel diseases (IBDs) peaks in the fertile age of both women and men. There is a significant lack of knowledge regarding disease-specific aspects of guiding IBD patients through conception, pregnancy, and delivery in clinical routine.

Summary: Patients with IBD often remain voluntarily childless, primarily due to a lack of knowledge.

Oncologic Surgery for Lower Gastrointestinal Tumors during Pregnancy: A Literature Review.

Background: Colorectal cancer (CRC) during pregnancy can be a challenging situation due to the spatial confinement of the tumor with the growing uterus carrying the fetus. It is one of the more common tumor entities occurring in pregnant women, and therefore, it has to be taken into account if "patients describe suspicious" symptoms.

Summary: Diagnosis and treatment are complex and require a specialized multidisciplinary team of visceral oncologists with expertise in colorectal surgery, gastrointestinal oncologists, gynecologists, obstetricians, and neonatologists to coordinate the optimal treatment plan with the patient.

Colorectal cancer at the anastomotic site following childhood surgery for hirschsprung disease: a rare case report.

Background: The present case of a colorectal adenocarcinoma at the anastomotic site of a colorectal anastomosis after childhood surgery for Hirschsprung disease is a rare report of such pathology. Possibly, the altered anatomy after Duhamel procedure may pose a risk for carcinogenesis in those patients. The previously surgically opened plane of the mesorectal fascia, which is usually dissected during total mesorectal excision in rectal cancer, and the impossibility to differentiate from colon or rectal cancer in this case influence oncologic treatment strategies.

The sagitta in 3D reconstruction of linea alba on routine CT scans is predictive of postoperative burst abdomen.

Purpose: Burst abdomen (BA) is a relevant complication after abdominal surgery that causes additional surgical procedures, prolonged hospital stays and long-term morbidity. Several underlying risk factors exist and have been characterized previously. Those risk factors consist of surgical and medical factors.

Hyperspectral imaging in living and deceased donor kidney transplantation.

Objective And Background: Hyperspectral imaging (HSI) is an innovative, noninvasive technique that assesses tissue and organ perfusion and oxygenation. This study aimed to evaluate HSI as a predictive tool for early postoperative graft function and long-term outcomes in living donor (LD) and deceased donor (DD) kidney transplantation (KT).

Patients And Methods: HSI of kidney allograft parenchyma from 19 LD and 51 DD kidneys was obtained intraoperatively 15 minutes after reperfusion.

Potential diagnostic value of high b-value computed diffusion-weighted imaging in hepatocellular carcinoma.
