Trans-Umbilical Lymphadenectomy Using an Articulating Bipolar Vessel-Sealing Device (TULAB) during Robotic Surgery for Gastric Cancer: Enhancing the Surgeon's Eye for Reduced-Port Robotic Gastrectomy.

Background: Docking the scope and instruments through a multi-channel trocar has enabled reduced-port robotic distal gastrectomy (RRDG) for gastric cancer. To facilitate lymphadenectomy over the anatomical hindrances during RRDG, we recently introduced the Vessel Sealer Extend (VSE) (Intuitive Surgical, Sunnyvale, CA, USA), a bipolar vessel-sealing device (BVSD) with an articulating jaw.

Methods: From May 2020 to August 2023, we performed RRDG to treat T1 gastric cancer.

Case Report: Single-port laparoscopic total gastrectomy for gastric cancer in patient with situs inversus totalis.

Situs inversus totalis (SIT) is a rare anatomical condition, where all the viscera appear in its reverse position. Although minimally invasive surgery has evolved to achieve totally laparoscopic gastrectomy for gastric cancer patients with SIT, it is difficult to perform lymphadenectomy in such a transposed anatomical condition. Recently, we performed a single-port laparoscopic total gastrectomy (SPTG) for gastric cancer in a patient with SIT.

Adverse Effects on Work and Daily Life Interference among Healthcare Workers after the First and Second ChAdOx1 and BNT162b2 COVID-19 Vaccine Doses.

Only few surgeons have tried to perform laparoscopic combined resection for T4b gastric cancer. The purpose of this study was to investigate the feasibility of laparoscopic combined resection through a comparison of the clinical outcomes between cT4a and cT4b cases. We reviewed the medical charts of patients who underwent laparoscopic gastrectomy for clinically T4 gastric cancer from May 2014 and July 2018.

Retrograde installation of percutaneous transhepatic negative-pressure biliary drainage stabilizes pancreaticojejunostomy after pancreaticoduodenectomy: a retrospective cohort study.

Background: Leakage from the pancreatoenteric anastomosis has been one of the major complications of pancreaticoduodenectomy (PD). The aim of this study was to investigate the feasibility of retrograde installation of percutaneous transhepatic negative-pressure biliary drainage (RPTNBD), as part of which the drainage tube is intraoperatively inserted into the bile duct and afferent loop by surgical guidance to reduce pancreaticoenteric leakage after PD.

Methods: We retrospectively reviewed the medical records of the patients who underwent pylorus-preserving PD or Whipple's operation for a malignant disease between June 2012 and August 2016.

Laparoscopic anatomical S3 segmentectomy by the glissonian approach.

Background: In an attempt to preserve hepatic volume in cases of severe cirrhosis, isolated resection of segment 3 (Sg3) may be beneficial [1-3]. We describe a laparoscopic anatomical Sg3 segmentectomy via an extrahepatic Glissonian approach.

Video: First, the falciform and coronary ligament were dissected.

Laparoscopic anatomical S7 segmentectomy by the intrahepatic glissonian approach.

Background: Laparoscopic anatomical liver resection for posterosuperior lesions is challenging [1,2] A technique of anatomical liver resection with intrahepatic Glissonian approach in open surgery has been published [3]. However, few articles report this technique via the laparoscopic approach [4]. We report a case of laparoscopic anatomical S7 segmentectomy using the Glissonian pedicle approach.

A case report of intrahepatic bile duct confluence anomalies in VACTERL syndrome.

Rationale: The clinical manifestations of VACTERL association include vertebral anomalies, anal atresia, congenital heart diseases, tracheoesophageal fistula, renal dysplasia, and limb abnormalities. The association of intrahepatic anomalies and VACTERL syndrome is a rare coincidence. VACTER syndrome and intrahepatic bile drainage anomalies might be genetically related.

One-Stage Complete Resection of Cholesteatoma With Labyrinthine Fistula: Hearing Changes and Clinical Outcomes.

Objectives: To evaluate long-term hearing changes and surgical outcomes for middle ear cholesteatoma with labyrinthine fistula following complete surgical removal of the cholesteatoma matrix.

Recognizable clinical subtypes of obstructive sleep apnea across international sleep centers: a cluster analysis.

Study Objectives: A recent study of patients with moderate-severe obstructive sleep apnea (OSA) in Iceland identified three clinical clusters based on symptoms and comorbidities. We sought to verify this finding in a new cohort in Iceland and examine the generalizability of OSA clusters in an international ethnically diverse cohort.

Methods: Using data on 972 patients with moderate-severe OSA (apnea-hypopnea index [AHI] ≥ 15 events per hour) recruited from the Sleep Apnea Global Interdisciplinary Consortium (SAGIC), we performed a latent class analysis of 18 self-reported symptom variables, hypertension, cardiovascular disease, and diabetes.

Alternative Biomarkers for Combined Biology.

Chemotherapy-related cardiac dysfunction (CRCD) has challenged clinicians to hesitate in using cardiotoxic agents such as anthracycline and several protein kinase inhibitors. As early detection of CRCD and timely cessation of cardiotoxic agents became a strategy to avoid CRCD, cardiac troponin and natriuretic peptide are measured to monitor cardiotoxicity; however, there are inconsistencies in their predictability of CRCD. Alternative biomarkers have been researched extensively for potential use as more sensitive and accurate biomarkers.

Protective effect of a purified polyphenolic extract from Ecklonia cava against noise-induced hearing loss: Prevention of temporary threshold shift.

Objective: Noise is one of the most common causes of hearing loss. Approximately 16% of American teenagers (12-19 years) have hearing loss caused by loud noise. The implication of noise-induced hearing loss (NIHL) in teenagers has received increasing attention.

Detection of Mycobacterium tuberculosis complex in sputum specimens using a loop-mediated isothermal amplification assay in Korea.

Tuberculosis (TB), an infectious disease caused by Mycobacterium tuberculosis complex (MTC), remains one of the leading causes of death in the world. In Korea, the current prevalence of multidrug-resistant TB (MDR-TB) poses a major problem. The most common method for diagnosing TB in developing countries is sputum smear microscopy; however, the sensitivity of this test is relatively low and it usually requires well-trained laboratory staff.

Association of total marine fatty acids, eicosapentaenoic and docosahexaenoic acids, with aortic stiffness in Koreans, whites, and Japanese Americans.

Background: Few previous studies have reported the association of aortic stiffness with marine n-3 fatty acids (Fas) in the general population. The aim of this study was to determine the combined and independent associations of 2 major marine n-3 FAs, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), with aortic stiffness evaluated using carotid-femoral pulse wave velocity (cfPWV) in Korean, white, and Japanese American men.

Methods: A population-based sample of 851 middle-aged men (299 Koreans, 266 whites, and 286 Japanese Americans) was examined for cfPWV during 2002-2006.
