Objective: To investigate the multidimensional effects of an interactive video health intervention on the quality of life and clinical rehabilitation indicators of patients with early postoperative bowel obstruction. Methods: The study consists of two phases. Phase 1 (January 2019-December 2020) involves the development and psychometric validation of a Postoperative Quality of Life Assessment Scale for Early Intestinal Obstruction, with approximately 150 patients. Phase 2 (January 2021-January 2025) is a randomized controlled trial enrolling about 310 eligible patients (aged 18-75 years, with basic cognitive ability, diagnosed with early postoperative bowel obstruction after abdominal surgery). Participants are randomly assigned to either a control group (conventional care, including condition monitoring, basic treatment, and non-structured health education) or a study group (conventional care plus an interactive video health intervention consisting of five modular videos covering disease knowledge, rehabilitation, and diet, initiated 24 hours post-surgery). Primary and secondary outcomes will include quality of life (assessed with the validated scale), clinical rehabilitation indicators (such as obstruction relief time and hospitalization duration), electrogastrogram parameters, and gut microbiota diversity (16S rRNA sequencing).

Standard conventional care including condition monitoring, basic medical treatment (gastrointestinal decompression, fluid replacement, correction of water-electrolyte disorders), and non-structured health education. Represents the current standard of care for postoperative bowel obstruction patients without the additional video-based intervention component.
A structured interactive video intervention consisting of 5 modular videos covering disease knowledge, rehabilitation exercises, and dietary guidance. The videos use animation demonstrations, case analyses, and expert explanations, with interactive elements such as Q\&A sessions and polls. Initiated 24 hours post-surgery, patients can self-paced viewing using tablet devices with researcher support.

Quality of Life (QoL) Score
Scale consists of multiple domains assessing physical, psychological, and social functioning. Scores range from 0 to 100, with higher scores indicating better quality of life.
Time frame: Baseline (pre-intervention, within 24 hours after surgery) and at hospital discharge (average 8-10 days after randomization).
Time to Relief of Intestinal Obstruction
Time from randomization to relief of intestinal obstruction symptoms (abdominal pain, distension, and resumption of defecation/flatus), measured in hours using daily clinical evaluation and patient report.
Time frame: From randomization to hospital discharge (daily assessment, average 8-10 days)
Duration of Hospitalization
Total number of days from the date of surgery to the date of hospital discharge, as recorded in hospital medical records. This indicator reflects postoperative recovery efficiency and the impact of the interactive video intervention on clinical outcomes.
Time frame: From the day of surgery through hospital discharge (an average of 7-10 days)
Electrogastrogram (EGG) Parameters - Gastric Antrum Slow-Wave Amplitude
Gastric antrum slow-wave amplitude measured in microvolts (μV) using electrogastrogram at specified time points.
Time frame: 24 hours post-intervention initiati
Electrogastrogram (EGG) Parameters - Gastric Slow-Wave Frequency
Gastric slow-wave frequency measured in cycles per minute (cpm) using electrogastrogram at specified time points.
Time frame: 24 hours post-intervention initiation and
Title: Gut Microbiota Diversity (Shannon Index)
Alpha diversity of gut microbiota measured by Shannon index using 16S rRNA sequencing of fecal samples.
Time frame: First postoperative defecation (typically 3-5 days post-surgery)
