Evaluation of the gastric conduit perfusion using indocyanine green in thoracoscopic esophagectomy for esophageal cancer.

Objective: Indocyanine green has been used in the assessment of the gastric conduit perfusion in thoracoscopic esophagectomy to prevent malperfusion-associated anastomotic leak. This study aims to evaluate the initial results of investigating the gastric conduit perfusion with indocyanine green in the surgical treatment of esophageal cancer.

Patients And Methods: This cross-sectional descriptive study was carried out on 54 esophageal cancer patients undergoing thoracoscopic esophagectomy and gastric conduit reconstruction.

Novel Water Probe for High-Frequency Focused Transducer Applied to Scanning Acoustic Microscopy System: Simulation and Experimental Investigation.

A scanning acoustic microscopy (SAM) system is a common non-destructive instrument which is used to evaluate the material quality in scientific and industrial applications. Technically, the tested sample is immersed in water during the scanning process. Therefore, a robot arm is incorporated into the SAM system to transfer the sample for in-line inspection, which makes the system complex and increases time consumption.

Falciform technique in laparoscopic revision of distal catheter obstruction: an evaluation.

Background: Ventriculoperitoneal (VP) shunting is a cornerstone treatment for hydrocephalus, a condition characterized by the abnormal accumulation of cerebrospinal fluid in the ventricles of the brain. Despite its efficacy, this procedure is associated with various complications, among which distal catheter obstruction poses significant challenges. This study aimed to evaluate the effectiveness of the in laparoscopic revision of distal catheter obstructions, offering a novel approach to mitigate this prevalent issue.

Retrosternal herniation of transverse colon following minimal invasive esophagectomy causing dysphagia: A case report.

Introduction And Importance: Minimally invasive esophagectomy has emerged as the established standard for treating esophageal cancer. The gastric graft is usually placed in the posterior mediastinum or the retrosternal tunnel for reconstruction. Hiatal hernia occurrence is more common in the posterior mediastinal reconstruction and is more frequently observed in laparoscopic compared to open approach.

Intrathoracic herniation of retrosternal gastric conduit after thoracolaparoscopic esophagectomy causing gastric conduit obstruction: A case report.

Introduction And Importance: Intrathoracic herniation of gastric conduit (IHGC) is a specific complication following esophagectomy with retrosternal gastric pull-up but is not well recognized. Diagnosis and management are challenging due to the lack of literature reviews.

Case Presentation: We report a 50-year-old man where a reconstructed gastric conduit hernia into the mediastinal pleural cavity after esophagectomy.

Giant cystic lymphangioma of right mesocolon: A case report.

Introduction: Cystic lymphangiomas are rare benign tumors of the lymph vessels and are usually found in children. However, abdominal cystic lymphangioma in mesocolon is extremely rare in adult patients.

Presentation Of Case: We reported a 15-year-old female with giant cystic lymphangioma of the right mesocolon.

The Efficacy of Transanal Total Mesorectal Excision: a Preliminary Vietnamese Report.

Introduction: The e physical anatomical characteristics of Vietnamese people are similar to those of other East Asian populations, with a deep and narrow pelvis but an average body mass index (BMI) among patients at the advanced stage of rectal cancer.

Aim: This study aimed to prospectively evaluate the short-term outcomes of transanal total mesorectal excision (TaTME) for rectal cancer treatment in a Vietnamese population.

Methods: A total of 64 patients who underwent TaTME were included in this study.

Improved Depth-of-Field Photoacoustic Microscopy with a Multifocal Point Transducer for Biomedical Imaging.

In this study, a photoacoustic microscopy (PAM) system based on a multifocal point (MFP) transducer was fabricated to produce a large depth-of-field tissue image. The customized MFP transducer has seven focal points, distributed along with the transducer's axis, fabricated by separate spherically-focused surfaces. These surfaces generate distinct focal zones that are overlapped to extend the depth-of-field.

Design, Fabrication, and Evaluation of Multifocal Point Transducer for High-Frequency Ultrasound Applications.

The present study illustrates the design, fabrication, and evaluation of a novel multifocal point (MFP) transducer based on polyvinylidene fluoride (PVDF) film for high-frequency ultrasound application. The fabricated MFP surface was press-focused using a computer numerical control (CNC) machining tool-customized multi-spherical pattern object. The multi-spherical pattern has five spherical surfaces with equal area and connected continuously to have the same energy level at focal points.
