The authors present an original reconstruction technique after pancreaticoduodenectomy, with anastomosis between the pancreatic stump and the posterior wall of the stomach, using two Roux-en-Y loops to separate the hepaticojejunostomy from the pancreaticogastrostomy and gastrojejunostomy in order to reduce postoperative complications and mortality. Eighteen consecutive patients underwent the procedure. There was no mortality and no pancreaticogastrostomy leaks occurred. Two (11.1%) gastric bleeds occurred in the first two cases. Twelve cases (66.6%) presented alimentary emesis on postoperative day 5 or 6 after food intake. Three patients (16.6%) had postoperative diarrhea. There were no complications calling for reoperation. The mean hospital stay was 14.4 days. No significant late complications were observed. The procedure is easy and safe with no mortality and with one of the lowest complication rates in the literature.

Background And Purpose: Evidence for long-term outcomes following acetabular fractures in older adults is limited. We aimed to evaluate mortality, complications, and need for subsequent surgical procedures in operatively and nonoperatively treated older patients with acetabular fractures.
Methods: Patients aged ≥ 70 years with acetabular fractures treated at Uppsala University Hospital between 2010 and 2020 were included.

Objectives: This meta-research assessed methodologies used for evaluating peri-implant marginal bone levels on digital periapical radiographs in randomised clinical trials published between 2019 and 2023.
Methods: Articles were searched in four databases. Data on methods for assessing peri-implant marginal bone levels were extracted.

Objectives: This study aimed to develop an automated method for generating clearer, well-aligned panoramic views by creating an optimized three-dimensional (3D) reconstruction zone centered on the teeth. The approach focused on achieving high contrast and clarity in key dental features, including tooth roots, morphology, and periapical lesions, by applying a 3D U-Net deep learning model to generate an arch surface and align the panoramic view.
Methods: This retrospective study analyzed anonymized cone-beam CT (CBCT) scans from 312 patients (mean age 40 years; range 10-78; 41.

Background: The topic of the effect of the patient table on attenuation in myocardial perfusion imaging (MPI) SPECT is gaining new relevance due to deep learning methods. Existing studies on this effect are old, rare and only consider phantom measurements, not patient studies. This study investigates the effect of the patient table on attenuation based on the difference between reconstructions of phantom scans and polar maps of patient studies.

Purpose: Pulmonary perfusion imaging is a key lung health indicator with clinical utility as a diagnostic and treatment planning tool. However, current nuclear medicine modalities face challenges like low spatial resolution and long acquisition times which limit clinical utility to non-emergency settings and often placing extra financial burden on the patient. This study introduces a novel deep learning approach to predict perfusion imaging from non-contrast inhale and exhale computed tomography scans (IE-CT).
