Utility of endoscopic pressure study integrated system for gastroesophageal reflux disease after endoscopic antireflux therapy.

Objectives: The endoscopic pressure study integrated system (EPSIS) measures intragastric pressure (IGP) during esophagogastroduodenoscopy. Previous research demonstrated that EPSIS correlates with the 24-h impedance-pH (MII-pH) test and shows lower maximum IGP (IGP-Max) and a flatter waveform gradient in gastroesophageal reflux disease (GERD) patients, attributed to lower esophageal sphincter dysfunction. Although endoscopic antireflux therapy (EARTh) is effective for GERD, the MII-pH monitoring, the gold standard for assessing treatment outcomes, requires hospitalization and can be a burden.

Role of balloon dilation test in identifying suitable candidates for gastric peroral endoscopic myotomy.

Background: Predicting successful outcomes of gastric peroral endoscopic myotomy (G-POEM) is essential for identifying patients who are most likely to benefit from the procedure. This study aimed to evaluate the utility of the balloon dilation test (BDT) in optimizing patient selection for G-POEM.

Methods: A retrospective study was conducted from February 2021 to December 2023, including patients with refractory gastroparesis unresponsive to conventional medical treatments.

Persistent body-weight change on achalasia and peroral endoscopic myotomy: a multicenter cohort study.

Background: The distribution of body weight in patients with achalasia and after peroral endoscopic myotomy (POEM) has not been investigated. The role of body weight assessment after treatment remains unclear.

Methods: Using the multicenter achalasia cohort, the frequency of underweight (body mass index [BMI] < 18.

Accuracy of cephalometric landmark and cephalometric analysis from lateral facial photograph by using CNN-based algorithm.

Cephalometric analysis is the primary diagnosis method in orthodontics. In our previous study, the algorithm was developed to estimate cephalometric landmarks from lateral facial photographs of patients with normal occlusion. This study evaluates the estimation accuracy by the algorithm trained on a dataset of 2320 patients with added malocclusion patients and the analysis values.

Position statement of the World Endoscopy Organization: Role of endoscopy in screening, diagnosis, and treatment of esophageal superficial squamous neoplasia.

Esophageal squamous cell carcinoma (ESCC) remains a significant global health challenge, being the sixth leading cause of cancer mortality with pronounced geographic variability. The incidence rates range from 125 per 100,000 in northern China to 1-1.5 per 100,000 in the United States, driven by environmental and lifestyle factors such as tobacco and alcohol use, dietary habits, and pollution.

Phase concept: Novel dynamic endoscopic assessment of intramural antireflux mechanisms (with video).

Objectives: The gastroesophageal junction (GEJ) consists of various anatomical components that together form a barrier to prevent reflux of gastric content. This study introduces a novel phase concept to dynamically evaluate the antireflux barrier (ARB) during endoscopy and analyzes its functionality.

Methods: We reviewed previously the recorded endoscopic videos of subjects who underwent the endoscopic pressure study integrated system (EPSIS) from February to April 2024 for indications other than gastroesophageal reflux disease symptoms.

Effect of body mass index on post-treatment oral function in patients with oral cancer: a cross-sectional study.

This single-center cross-sectional study used sequential sampling to examine the influence of body mass index (BMI) on oral function after oral cancer treatment. Patients who completed primary oral cancer treatment between September 2019 and March 2023 (102 patients, 74 male [72.5%] and 28 female [27.

Predictors of Postoperative Persistent Low Back Pain Following Lumbar Fusion in Patients Older than 75 Years: An Analysis of a Minimum 2-Year Follow-Up.

Objective: This study aimed to evaluate preoperative and perioperative predictors associated with persistent low back pain (LBP) following lumbar fusion in patients aged >75 years.

Methods: This single-center retrospective study examined 310 patients aged >75 years who underwent lumbar fusion for lumbar degenerative disease (104 males, 206 females; mean age, 79 [75-90] years). The visual analog scale (VAS) score for LBP was examined preoperatively and 2-year postoperatively.

Intra-Articular Corrective Osteotomy for Distal Radial Intra-Articular Malunion Using Patient-Matched Instruments: A Prospective, Multicenter, Open-Label, Single-Arm Trial.

Background: Corrective osteotomy for intra-articular malunion is a challenging procedure. However, recent advancements, including patient-matched instruments created on the basis of preoperative computer simulation, enable accurate intra-articular correction. We hypothesized that intra-articular corrective osteotomy using patient-matched instruments for the treatment of distal radial intra-articular malunion would reduce intra-articular deformity and restore wrist function at 12 months of follow-up.

Loop9 closure technique for mucosal defects after colorectal endoscopic submucosal dissection (with video).

Mucosal defect closure after colorectal endoscopic submucosal dissection (ESD) has the potential to reduce the occurrence of delayed adverse events (AEs) such as bleeding and perforation. This study aimed to assess the feasibility and effectiveness of the Loop9 method for closing mucosal defects following colorectal ESD. A retrospective single-center study was conducted using prospectively collected data from May 2020 to March 2023.

Patient of Congenital Absence of a Lumbar Pedicle With Nerve Root Anomaly Presenting With Ipsilateral Foraminal Stenosis by Vertebral Fracture.

Patients with congenital absence of a lumbar pedicle and nerve root anomaly presenting with ipsilateral foraminal stenosis are extremely rare. An 80-year-old man had low back and right thigh pain. Radiographs and computed tomography (CT) showed L3 vertebral body fracture and the absence of the right L3 lumbar pedicle.

Impact of peroral endoscopic myotomy on the endoscopic pressure study integrated system.

Objectives: The endoscopic pressure study integrated system (EPSIS) is an endoscopic diagnostic system utilized for evaluation of lower esophageal sphincter function. Although previous studies have determined that EPSIS was effective as a tool for the diagnosis of achalasia, it remains uncertain if EPSIS can detect significant changes before and after peroral endoscopic myotomy (POEM), which is the premier treatment for achalasia. This study aimed to evaluate the effectiveness of EPSIS as an objective diagnostic tool for assessing the clinical effect of POEM.

Endoscopic resection for gastric submucosal tumors: A single-center experience in Japan.
