Lymphoepithelial carcinoma of the submandibular gland in a Japanese male: A case report.

Lymphoepithelial carcinoma of the submandibular gland is an extremely rare condition; therefore, no clear clinical features or established treatment is available for this. A 58-year-old Japanese man who came to our hospital with the complaint of swelling of the left submandibular region was diagnosed with stage IVa, T4aN2bM0 lymphoepithelial carcinoma of the submandibular gland. We also examined the relationship between the tumor and Epstein-Barr virus by Epstein-Barr virus encoded ribonucleoprotein in situ hybridization.

Complications including dysphagia following transoral non-robotic surgery for pharyngeal and laryngeal squamous cell carcinoma: A retrospective multicenter study.

Methods: We compared clinical information, surgical complications, and swallowing function in patients who underwent transoral nonrobotic surgery for laryngo-pharyngeal squamous cell carcinoma between 2015 and 2021 in a multicenter retrospective study.

Results: Six hundred and forty patients were included.

Impact of cervical lymph node metastasis on transoral surgery for hypopharyngeal squamous cell carcinoma: A retrospective multicenter study.

Background: Hypopharyngeal carcinoma is likely to spread to the lymph nodes, but there is no established strategy for management in transoral surgery.

Methods: We compared oncologic and functional outcomes in a retrospective multicenter study of patients who underwent transoral surgery for hypopharyngeal carcinoma between 2015 and 2021.

Results: Two-hundred and thirty-two patients were included.

Electron Transfer Reduction by Hydrogen Creates Porosity in Tantalate Crystals and Produce Multifunctionality.

Contrary to partially substituted systems, WO molecular sieves that exclusively comprise a d transition metal ion and do not possess template ions in the cavity are a new class of materials for photocatalysis owing to their framework structure. Because WO thermodynamically lacks proton-reduction capability, exploring diverse synthetic approaches of other materials is desirable for facilitating utilization as H evolution and water splitting systems. Herein, we report an efficient approach for the protonation of AgTaO to afford HTaO for application as a H molecular sieve.

Local recurrence and metachronous multiple cancers after transoral nonrobotic surgery for pharyngeal and laryngeal squamous cell carcinoma: A retrospective multicenter study.

A multi-institutional retrospective study of 340 cases of sinonasal malignant tumor.

Objective: Sinonasal malignant tumors (SNMT) are relatively rare among head and neck malignant tumors. Most are squamous cell carcinomas, and malignant melanomas, olfactory neuroblastomas, adenoid cystic carcinomas, sarcomas, and others also occur. The most common primary site of nasal sinus squamous cell carcinoma is the maxillary sinus.

Buccal fat pad flap for transoral repair of radiation-induced necrosis in the lateral oropharyngeal wall.

Soft tissue necrosis (STN) is a late toxicity after radiotherapy. Extensive tissue defects due to STN near the carotid artery, such as in the lateral oropharyngeal wall, may lead to infectious pseudoaneurysms associated with fatal bleeding. Such defects are usually treated with transcervical reconstructive surgeries, which are highly invasive and technically difficult.

Deep learning for hetero-homo conversion in channel-domain for phase aberration correction in ultrasound imaging.

Echo imaging in ultrasound computed tomography (USCT) using the synthetic aperture technique is performed with the assumption that the speed of sound is constant in the system. However, tissue heterogeneity causes a mismatch between the predicted arrival time and the actual arrival time of the echo signal, which will result in phase aberration, leading to the quality degradation of the reconstructed B-mode image. The conventional correction methods that use the correlation of each different channel require the presence of strong point scatterers and involve the problem of local solutions due to excessive correction.

Impact of the Patency of Inferior Mesenteric Artery on 7-Year Outcomes After Endovascular Aneurysm Repair.

Purpose: The impact of preoperative patent inferior mesenteric artery (IMA) on late outcomes following endovascular aneurysm repair (EVAR) remains unclear. This study aimed to investigate the specific influence of IMA patency on 7-year outcomes after EVAR.

Materials And Methods: In this retrospective cohort study, 556 EVARs performed for true abdominal aortic aneurysm cases between January 2006 and December 2019 at our institution were reviewed.

Purpose: Zone 0 landing in thoracic endovascular aortic repair (TEVAR) has recently gained increasing attention for the treatment of high-risk patients. The aim of this study was to compare the outcomes of total endovascular aortic arch repair between branched TEVAR (bTEVAR) and chimney TEVAR (cTEVAR) in the landing zone (LZ) 0.

Materials And Methods: This was a single-center, retrospective, and observational cohort study.

Risk Analysis of Aneurysm Sac Enlargement Caused by Type II Endoleak after Endovascular Aortic Repair.

Background: Although the preoperative risk factors associated with the occurrence of type II endoleak (ETII) after endovascular aortic repair (EVAR) have gradually become more evident, the preoperative risk factors associated with aneurysm sac enlargement caused by ETII remain unclear. This study aimed to determine the preoperative risk factors associated with aneurysm sac enlargement caused by ETII after EVAR.

Methods: This retrospective cohort study reviewed 519 EVARs performed for true abdominal aortic aneurysm between January 2006 and December 2018 at our institution.

Defect repair with fibrin glue/polyglycolic acid after endoscopic laryngopharyngeal cancer resection.

Objectives/hypothesis: In 2013, we introduced a modified technique for mucosal/muscle layer defect coverage with fibrin glue and polyglycolic acid (PGA) sheets (mMCFP technique) in patients undergoing endoscopic transoral surgeries for laryngopharyngeal cancers. This technique allows easy and convenient coverage of the wound surface, even when it involves the laryngopharyngeal lumen. To our knowledge, use of the MCFP technique for coverage of postoperative mucosal and/or muscle layer defects involving the laryngopharyngeal lumen has not been reported.

Clinical outcomes of end-flexible-rigidscopic transoral surgery (E-TOS) in patients with T1-selected T3 pharyngeal and supraglottic cancers.

Background: Endoscopic laryngo-pharyngeal surgery (ELPS), which is a transoral minimally invasive surgery using a gastrointestinal endoscope and a curved laryngopharyngeal retractor, is effective to treat primary lesions of superficial laryngopharyngeal cancers. To extend concepts of ELPS to invasive laryngopharyngeal cancers, we developed end-flexible-rigidscopic transoral surgery (E-TOS) from ELPS by changing a gastrointestinal endoscope to a flexible-tip rigid endoscope.

Aims/objectives: To retrospectively evaluate oncological outcomes and laryngopharyngeal functional preservation of E-TOS in patients with T1-selected T3 laryngopharyngeal cancers.

Quantitative evaluation of blood flow in each cerebral branch associated with zone 1-2 thoracic endovascular aortic repair.

Objectives: Optimal methods to quantitatively evaluate the blood flow in each cerebral artery after zone 1-2 thoracic endovascular aortic repair (TEVAR) remain unknown. Our objective was to evaluate the differences between preoperative and postoperative cerebral artery blood flows after zone 1-2 debranching TEVAR (dTEVAR).

Methods: Between January 2016 and August 2018, a prospective analysis of the blood flow in both the internal carotid artery and the vertebral artery in 16 patients before and after zone 1-2 dTEVAR was conducted.

Successful Hybrid Zone 0 Landing Thoracic Endovascular Aortic Repair for Ascending Aortic Pseudoaneurysm after Bentall Procedure and Coronary Artery Bypass Grafting in Takayasu Arteritis.

Pseudoaneurysm at the suture line is one of the most common complications in aortic surgery for Takayasu arteritis (TA) and is associated with a high mortality rate. A 52-year-old man with TA, who previously underwent the Bentall procedure and 2 redo surgeries for coronary artery obstruction and a pseudoaneurysm of a coronary button, was diagnosed with an anastomotic pseudoaneurysm in the ascending aorta. Hybrid zone 0 debranching thoracic endovascular aortic repair was performed, and the patient was discharged uneventfully on postoperative day 8.
