Objective: Laparoscopic cholecystectomy (LC) is the most common minimally invasive surgery in Hong Kong. However, ambulatory LC is not a common practice in Hong Kong. This study aims to identify the causes of long hospital stay after elective LC and to delineate a guideline for ambulatory LC.
Methods: A retrospective analysis of 278 patients who underwent successful elective LC in a single unit between 1 January 2002 and 31 December 2003 was performed. They were divided into two groups: LS group had a long hospital stay (>24 hours after operation) and SS group had a short hospital stay. A total of 18 variables, including five patient variables, nine operative variables and four postoperative variables, were identified for univariate analysis. Significant pre- and postoperative factors were included in the multivariate analysis to identify independent predictive factors for long hospital stay.
Results: Of the 278 patients, 118 (44.2%) could be discharged within 24 hours, while 149 (55.8%) had long hospital stay. Nine significant factors were identified in the univariate analysis; three independent factors were found to predict long hospital stay in the multivariate analysis. Patients with age more than 60 years had double risk of long hospital stay. Patients who could not tolerate diet within 8 hours or took more than two tablets of oral analgesia (dologesics) had a four- and threefold increase in risk of long hospital stay, respectively.
Conclusion: With careful patient selection, optimal postoperative pain control and early resumption of diet with better management of postoperative nausea and vomiting, ambulatory LC was feasible and safe.

Assessing the impact of magnesium-based nutritional education on lipid profiles in individuals with type 2 diabetes mellitus: a quasi-experimental study.

Department of Clinical Nutrition, Faculty of Applied Medical Sciences, King Abdulaziz University, Jeddah, Saudi Arabia.
Background: The potential therapeutic role of magnesium (Mg) in type 2 diabetes mellitus (T2DM) remains insufficiently studied despite its known involvement in critical processes like lipid metabolism and insulin sensitivity. This study examines the impact of Mg-focused nutritional education on lipid profile parameters, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) in T2DM patients.
Methods: Thirty participants with T2DM were recruited for this within-subject experimental study.
Delta large-channel endoscopy versus unilateral biportal endoscopy decompressive laminectomy for lumbar spinal stenosis: a prospective randomized controlled trial.
J Orthop Surg Res
January 2025
Center of Medical Genetics, West China Second University Hospital, Sichuan University, Chengdu, Sichuan, 610041, China.
Background: Delta large-channel endoscopy and unilateral biportal endoscopy (UBE) are prominent minimally invasive techniques for treating lumbar spinal stenosis, known for minimal tissue damage, clear visualization, and quick recovery. However, rigorous controlled research comparing these procedures is scarce, necessitating further investigation into their respective complications and long-term effectiveness. This randomized controlled trial aims to compare their perioperative outcomes, focusing on postoperative recovery and complications over time.

Purpose: The purpose of this study was to use the advanced technique of Network Intervention Analysis (NIA) to investigate the trajectory of symptom change associated with the effects of self-control training on youth university students' chronic ego depletion aftereffects.
Methods: The nine nodes of chronic ego depletion aftereffects and integrated self-control training were taken as nodes in the network and analyzed using NIA. Networks were computed at the baseline, at the end of treatment, at 1-, 3-, 6-, 9- and 12-month follow up.

Objective: To investigate the application value of arthroscopic channel modification in meniscal injury repair.
Methods: We retrospectively analyzed the data of 100 patients with meniscus injuries treated with knee arthroscopy from December 2022 to December 2023 and divided them into a control group and a modified group according to the application of "arthroscopic access modification technology". We compared the operation time, postoperative hospitalization time, VAS score, Lysholm knee function score, postoperative complications, and postoperative images of the patients in these two groups.
