Abstract
BACKGROUND Gastric intramural hematoma is a rare disease. Here we report a case of spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma. CASE PRESENTATION A 75-years-old man was admitted to our department with complaints of abdominal pain. He underwent a whole abdominal computed tomography (CT) scan in the emergency department, which showed extensive thickening of the gastric wall in the gastric body and sinus region with enlarged surrounding lymph nodes, localized thickening of the intestinal wall in the transverse colon, localized indistinct demarcation between the stomach and transverse colon, and a small amount of fluid accumulation in the abdominal cavity. Immediately afterwards, he was admitted to our department, and then we arranged a computed tomography with intravenously administered contrast agent showed a spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma. Therefore, we treated him with anticoagulation and conservative observation. During his stay in the hospital, he was given low-molecular heparin by subcutaneous injection for anticoagulation therapy, and after discharge, he was given oral anticoagulation therapy with rivaroxaban. At the follow-up of more than 4 months, most of the intramural hematoma was absorbed and became significantly smaller, and the intermural hematoma of the superior mesenteric artery was basically absorbed, which also confirmed that the intramural mass was an intramural hematoma. CONCLUSION A gastric intramural hematoma should be considered, when an intra-abdominal mass was found to be attached to the gastric wall. Proper recognition of gastric intramural hematoma can reduce the misdiagnosis rate of confusion with gastric cancer.

Abstract
BACKGROUND Omental artery aneurysm (OAA) is an extremely rare visceral artery aneurysm. Ruptured OAAs are associated with a high mortality rate. Transcatheter arterial embolization (TAE) has been used to treat OAA in recent years. However, the risk of omental ischemia due to TAE remains unclear. Therefore, this study aimed to investigate the efficacy and safety of TAE of OAA as a first-line treatment. METHODS Fifteen patients with true aneurysms or pseudoaneurysms who underwent OAA-TAE between 1 April 2010 and 31 December 2022 were included in this study. The technical and clinical outcomes, the incidence of omental infarction after TAE as a major complication, OAA-TAE techniques, radiological findings on computed tomography angiography and angiogram, and patient characteristics were evaluated. RESULTS Fifteen patients (nine men, six women; age, 69.8 ± 18.59 years) underwent TAE of OAAs (mean aneurysm size of 9.30 ± 6.10 mm) located in the right gastroepiploic (n = 9), left gastroepiploic (n = 1), and epiploic (n = 5) arteries. All patients with ruptured (n = 6) and unruptured (n = 9) OAA successfully underwent TAEs using coils, n-butyl-2-cyanoacrylate, or gelatin sponges. Hepatic artery thrombosis and coil migration were observed during the procedure; however, these adverse events were manageable. Transfusion of red blood cell units (4.66 ± 1.63 units) was required only in cases with ruptured OAAs after TAE. Additional surgery or TAE due to rupture or rerupture of OAA and omental infarction was not required during the postoperative and follow-up periods. CONCLUSION The OAA-TAE can effectively treat ruptured and unruptured OAAs, and the risk of omental infarction after OAA-TAE may not be high.

Optimization of anastomotic technique and gastric conduit perfusion with hyperspectral imaging and machine learning in an experimental model for minimally invasive esophagectomy. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023:S0748-7983(23)00444-4. [PMID: 37105869 DOI: 10.1016/j.ejso.2023.04.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Revised: 03/26/2023] [Accepted: 04/12/2023] [Indexed: 04/29/2023]
Abstract
INTRODUCTION Esophagectomy is the mainstay of esophageal cancer treatment, but anastomotic insufficiency related morbidity and mortality remain challenging for patient outcome. Therefore, the objective of this work was to optimize anastomotic technique and gastric conduit perfusion with hyperspectral imaging (HSI) for total minimally invasive esophagectomy (MIE) with linear stapled anastomosis. MATERIAL AND METHODS A live porcine model (n = 58) for MIE was used with gastric conduit formation and simulation of linear stapled side-to-side esophagogastrostomy. Four main experimental groups differed in stapling length (3 vs. 6 cm) and simulation of anastomotic position on the conduit (cranial vs. caudal). Tissue oxygenation around the anastomotic simulation site was evaluated using HSI and was validated with histopathology. RESULTS The tissue oxygenation (ΔStO2) after the anastomotic simulation remained constant only for the short stapler in caudal position (-0.4 ± 4.4%, n.s.) while it was impaired markedly in the other groups (short-cranial: -15.6 ± 11.5%, p = 0.0002; long-cranial: -20.4 ± 7.6%, p = 0.0126; long-caudal: -16.1 ± 9.4%, p < 0.0001). Tissue samples from avascular stomach as measured by HSI showed correspondent eosinophilic pre-necrotic changes in 35.7 ± 9.7% of the surface area. CONCLUSION Tissue oxygenation at the site of anastomotic simulation of the gastric conduit during MIE is influenced by stapling technique. Optimal oxygenation was achieved with a short stapler (3 cm) and sufficient distance of the simulated anastomosis to the cranial end of the gastric conduit. HSI tissue deoxygenation corresponded to histopathologic necrotic tissue changes. The experimental model with HSI and ML allow for systematic optimization of gastric conduit perfusion and anastomotic technique while clinical translation will have to be proven.

Muro S, Akita K. Novel combination method of wide-range serial sectioning and 3D reconstruction visualizing both macro-level dynamics and micro-level interactions in an attempt to analyze the female pelvic floor. Anat Sci Int 2023:10.1007/s12565-023-00710-0. [PMID: 36882587 DOI: 10.1007/s12565-023-00710-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Accepted: 02/23/2023] [Indexed: 03/09/2023]
Abstract
The present report presents details of the method for combining wide-range serial sectioning and 3D reconstruction using an adult cadaver. For several decades, anatomists have utilized a variety of non-destructive three-dimensional (3D) visualization methods to complement gross anatomical analysis methods. These include vascular casting for the visualization of vascular morphology and micro-CT for the visualization of bone morphology. However, these conventional methods are restricted by the properties and sizes of the target structures. Here, we introduce a method to conduct 3D reconstruction based on wide-range serial histological sections from adult cadavers, which overcomes previous restrictions. An attempt at 3D visualization of the female pelvic floor muscles provides a detailed description of the procedure. Supplemental video and 3D PDF files allow multifaceted observation of 3D images. Wide-range serial sectioning visualizes morphology beyond the scope of conventional methods, while 3D reconstruction enables non-destructive 3D visualization of any structure that can be observed on a histological section, including skeletal muscle, smooth muscle, ligaments, cartilage, connective tissue, blood vessels, nerves, lymph nodes, and glands. The novel combination of both methods is instrumental in meso-anatomy, a discipline intermediate between macro-anatomy and micro-anatomy.

Abstract
Gastric intramural hematoma (GIH) is a rare disorder that usually arises secondary to another condition or intervention, and less often occurs without an identifiable cause. Computed tomography (CT), as performed in this case, is the diagnostic modality of choice. The treatment comprises conservative measures, a minimally invasive approach, or surgical intervention. We present a case of recurrent acute lymphoblastic leukemia (ALL) as a new etiology for GIH that was managed conservatively to highlight the importance of including GIH in the differential for a patient with ALL, a drop in hemoglobin level, and vague gastrointestinal symptoms.

Abstract
We herein report two autopsy cases with gastric injury associated with cardiopulmonary resuscitation (CPR). Case 1 was a 36-year-old woman who was found in cardiopulmonary arrest possibly caused by a fall from a height of 8 m. She received continuous manual chest compression with artificial ventilation while being transferred to the hospital. Autopsy revealed bruises on her left upper arm with a fracture to the left humerus and advanced pneumohemothorax that was associated with laceration of the left lung due to fracture of the dorsal left costa. Furthermore, complete rupture of the gastric wall (25 cm) was found without hemorrhage. Case 2 was an 85-year-old man found unconscious on the road. He had a history of oral anticoagulant administration, cognitive impairment, and gait disorder. He also received cardiac massage and manual artificial ventilation during CPR. Autopsy revealed severe head injury, possibly caused by a backward fall. His stomach was markedly dilated by air and a fresh intramural hematoma had extended into all layers of the stomach and adjacent omentum; however, injury of the abdominal wall was not evident. Histopathological investigation of the brain revealed advanced Alzheimer's disease and Lewy pathology, and the damaged neural tissue, which was positive for the amyloid precursor protein. We determined that the gastric injuries in both cases had been caused by CPR. We conclude that careful investigation is required for gastric injury cases to determine the etiology and correlation between gastric injury and cause of death when the victims receive CPR.
