AI Article Synopsis
- The study evaluated the use of ultrathin gastroscopes in the endoscopic pressure study integrated system (EPSIS) for assessing lower esophageal sphincter function by monitoring intragastric pressure.
- A retrospective analysis of 30 patients showed that the pressure metrics obtained with ultrathin gastroscopes significantly correlated with those from regular gastroscopes, although the values were consistently lower with the ultrathin option.
- The results suggest that ultrathin gastroscopes are a viable alternative for EPSIS, supporting their use in diagnosing lower esophageal sphincter issues.
Article Abstract
Objectives: The endoscopic pressure study integrated system (EPSIS) represents an innovative approach for evaluating lower esophageal sphincter function by monitoring intragastric pressure using diagnostic gastroscopes. This study aimed to assess the feasibility and validity of employing ultrathin gastroscopes for EPSIS.
Methods: A retrospective analysis was conducted on a database of consecutive patients who underwent EPSIS using both ultrathin and regular gastroscopes between September 2021 and October 2023. The study compared EPSIS parameters between the two gastroscope types to evaluate the correlation of key metrics.
Results: Thirty patients underwent EPSIS with both ultrathin and regular gastroscopes. Significant positive correlations were observed in the pressure waveform: maximum intragastric pressure (mmHg) (ρ = 0.82, P < 0.001) and intragastric pressure gradient (mmHg/s) (ρ = 0.80, P < 0.001) when comparing the two gastroscopes. Maximum intragastric pressure (15.5 [5.3-20.3] vs. 18.5 [3.4-21.6], P < 0.001) and pressure gradient (0.16 [0.013-0.41] vs. 0.24 [0.0039-1.13], P < 0.001), (median [range]) were significantly lower with ultrathin gastroscopes.
Conclusions: This study establishes that EPSIS parameters obtained with an ultrathin gastroscope exhibit a significant correlation with those obtained using a regular gastroscope, with each EPSIS parameter consistently lower. These findings support the viability of EPSIS for ultrathin gastroscopy and highlight its potential as a diagnostic tool for assessing lower esophageal sphincter function.

Ophthalmology, Royal Free Hospital, London, GBR.
Endoscopic cyclophotocoagulation (ECP) offers a viable alternative for managing advanced primary open-angle glaucoma (POAG) in patients at risk of ocular hypotony. We describe a case of a successful outcome with ECP in a patient who developed ocular hypotony secondary to Preserflo surgery. A 93-year-old South Asian male experienced significant visual field deterioration and ocular hypotony following Preserflo surgery on the left eye, complicated by a severe cough from COVID-19.

Lemmel syndrome involves a periampullary duodenal diverticulum (PAD), a pouch-like outpouching near the ampulla of Vater, compressing the common bile duct. We describe a case of severe abdominal pain in a patient who had a large periampullary diverticulum, managed with surgical intervention after an initial failed endoscopic retrograde cholangiopancreatography (ERCP). An elderly female patient in her early 90s arrived at the emergency department with severe cramping pain localized to the right upper quadrant of her abdomen, progressively intensifying over several weeks.

Septic arthritis of the sternoclavicular joint is a rare infectious arthritis in which the risk factors are reported to be such as diabetes, immunosuppression, and intravenous drug use. Due to a lack of prominent symptoms, delayed diagnosis can lead to severe complications such as mediastinitis and empyema. Advanced sternoclavicular septic arthritis can be a hidden etiology masked by severe symptoms.
