Objective: To evaluate the relationships between the location and extent of diffusion of free intraperitoneal air by multi-slice spiral CT (MSCT) and between the location and size of acute gastrointestinal perforation. Methods: This was a descriptive case series. We examined abdominal CT images of 33 patients who were treated for intraoperatively confirmed gastrointestinal perforation (excluding appendiceal perforation) in the Department of General Surgery, Nanfang Hospital between January and September 2022...

Small bowel obstruction (SBO) impacts the health care system and patient quality of life. Previously, we evaluated differences between medical and surgical admissions in the management of SBO. This study investigates indications for readmission based on original admission to medical (MS) or surgical services (SS). A retrospective chart review was performed for 799 patients aged 18 to 89 admitted between 2012 and 2019 with a diagnosis of SBO. Patient characteristics examined included length of stay (LOS), prior abdominal operations, prior SBO, use of small bowel follow through imaging, operative intervention, mortality, and 30-day readmission...

A 72-year-old man was referred to our hospital for the examination of a pancreatic head mass. Abdominal computed tomography revealed a contrasted 8-cm-diameter tumor extending from the dorsal pancreatic head to the porta hepatis. The preoperative diagnosis was challenging due to the absence of specific imaging findings and the inability to perform a biopsy. Positron emission tomography/computed tomography and diffusion-weighted imaging suggested a malignant tumor originating from the organs surrounding the pancreatic head...

Abdominal ultrasound is a key non-invasive imaging method for diagnosing liver, kidney, and gallbladder diseases, despite its clinical significance, not all individuals can undergo abdominal ultrasonography during routine health check-ups due to limitations in equipment, cost, and time. This study aims to use basic physical examination data to predict the risk of diseases of the liver, kidney, and gallbladder that can be diagnosed via abdominal ultrasound. Basic physical examination data contain gender, age, height, weight, BMI, pulse, systolic blood pressure (SBP), diastolic blood pressure (DBP), high-density lipoprotein (HDL), low-density lipoprotein (LDL), total cholesterol, triglycerides, fasting blood glucose (FBG), and uric acid-we established seven single-label predictive models and one multi-label predictive model...

Null Subtraction Imaging (NSI) is a novel beamforming technique that can produce B-mode images resulting in high spatial resolution and low computational cost compared to other beamforming techniques. Previous work has demonstrated that in addition to a beam pattern with a narrow main lobe and low side lobes, NSI can also reduce or mitigate grating lobes, which can appear when the array pitch is larger than one half the wavelength of the transmitted pulse. These grating lobes can result in imaging artifacts that produce clutter and lower contrast...

BACKGROUND: Population-wide research on potential new imaging biomarkers of the kidney depends on accurate automated segmentation of the kidney and its compartments (cortex, medulla, and sinus). METHODS: We developed a robust deep-learning framework for kidney (sub-)segmentation based on a hierarchical, three-dimensional convolutional neural network (CNN) that was optimized for multi-scale problems of combined localization and segmentation. We applied the CNN to abdominal magnetic resonance images from the population-based German National Cohort (NAKO) study...

BACKGROUND AND PURPOSE: The objective is to demonstrate feasibility of quantitative susceptibility mapping (QSM) in autosomal dominant polycystic kidney disease (ADPKD) patients and to compare imaging findings with traditional T1/T2w magnetic resonance imaging (MRI). METHODS: Thirty-three consecutive patients (11 male, 22 female) diagnosed with ADPKD were initially selected. QSM images were reconstructed from the multiecho gradient echo data and compared to co-registered T2w, T1w, and CT images...

A 58-year-old man who was an active smoker was admitted twice to the intensive care unit (ICU) of a tertiary referral thoracic center for severe hypercapnic acute respiratory failure and persistent bilateral chest radiograph opacities that were unchanged over the course of the two ICU admissions within a 3-month period (Fig 1). He had obesity (body mass index, 36 kg/m2 ), stage 3 vascular chronic renal insufficiency, and hebephrenic schizophrenia treated with haloperidol, carbamazepine, and cyamemazine. He reported chronic dyspnea on exertion, which worsened for 6 months...

AIM: To investigate the relationship of fat in the pancreas with time spent in different glycaemic ranges. METHODS: Abdominal magnetic resonance imaging at 3.0 Tesla was used to quantify fat in the pancreas as both continuous [i.e. intra-pancreatic fat deposition (IPFD)] and binary (i.e. fatty change of the pancreas vs. normal pancreas) variables. Dexcom G6 devices were used to collect continuous glucose monitoring data every 5 min over a continuous 7-day period...

INTRODUCTION: Endovascular aneurysm repair using iodinated contrast agents risks contrast-induced nephropathy, especially in high-risk patients. This technical note describes a contrast-free endovascular aneurysm repair (EVAR) protocol using preoperative imaging measurement and fibrin sealant (FS) filling. TECHNIQUE: Preoperative imaging measurement and intraoperative guidewire manipulation facilitated anatomical identification without contrast. After endograft deployment, the aneurysm sac was filled with FS if endoleak was indicated by pressure fluctuations...

PURPOSE: Contrast enhancement of the adrenal gland defined by computed tomography (CT) was previously analyzed as a prognostic factor for critically ill patients in various diseases. However, no study investigated this quantitative parameter in patients with acute mesenteric ischemia. Therefore, the aim of this study was to evaluate the prognostic value of the contrast enhancement of the adrenal glands in patients with clinically suspected AMI. METHODS: All patients with clinically suspected AMI were retrospectively assessed between 2016 and 2020...

The field of hernia surgery has seen many recent advances and continues to evolve. Care of the hernia patient begins preoperatively by ensuring adequate preparation for surgery with surgeons now having the opportunity to accurately predict risk which can aid with informed consent. Imaging studies can now help surgeons diagnose and plan hernia surgery on an individual level based on hernia characteristics as well as abdominal wall musculature. In the operating room, new technology and surgical techniques have allowed surgeons to become increasingly sophisticated with goals of reducing tension on midline closures, utilizing minimally invasive and robotic techniques, and availability of new and varied mesh prosthetics...

PURPOSE: : Endotension is a rare late complication characterized by an increase in sac size without any type of endoleak following endovascular aortic aneurysm repair (EVAR). Due to its rarity, few studies have demonstrated the mechanism behind and the management of endotension. In this study, we aimed to better understand the treatment and the long-term outcome of endotension in a single-center cohort.

AIM: Ileorectal anastomosis (IRA) following total abdominal colectomy (TAC) allows for resortation of bowel continuity but prior studies have reported rates of anastomotic leak (AL) to be as high as 23%. We aimed to report rates of AL and complications in a large cohort of patients undergoing IRA. We hypothesized that AL rates were lower than previously reported and that selective use of diverting loop ileostomy (DLI) is associated with decreased AL rates. METHOD: Patients undergoing TAC or end-ileostomy reversal with IRA, with or without DLI, between 1980 and 2021 were identified from a prospectively maintained institutional database and retrospectively analysed...
