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).

| Conventional care | Behavioral | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| 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. | Baseline (pre-intervention, within 24 hours after surgery) and at hospital discharge (average 8-10 days after randomization). |
| Measure | Description | Time Frame |
|---|---|---|
| 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. | From randomization to hospital discharge (daily assessment, average 8-10 days) |
| Measure | Description | Time Frame |
|---|---|---|
| Postoperative Quality of Life Assessment Scale Validation - Reliability Metrics | Internal consistency of the Postoperative Quality of Life Assessment Scale for Early Intestinal Obstruction, assessed using Cronbach's alpha (range 0-1; higher scores indicate better internal consistency). | At postoperative day 7 (single assessment after intervention) |

| Interactive Video Health Intervention | Behavioral | 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. |
|
| 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. |

| Postoperative Quality of Life Assessment Scale Validation - Construct Validity Metrics |
Construct validity of the Postoperative Quality of Life Assessment Scale for Early Intestinal Obstruction (PQOL-EO), assessed using Average Variance Extracted (AVE) and Composite Reliability (CR). Both are unitless indices (range 0-1), where higher values indicate better construct validity and internal consistency of the scale. |
| At postoperative day 7 (single assessment after intervention) |
| Expert Consensus Agreement on Questionnaire Items | Percentage of questionnaire items rated as "appropriate" or "highly relevant" by an expert panel using a 5-point Likert scale (1 = not relevant to 5 = highly relevant). Higher scores indicate greater content validity and expert consensus regarding the Postoperative Quality of Life Assessment Scale for Early Intestinal Obstruction (PQOL-EO). | During the pre-intervention development phase (single assessment prior to participant enrollment) |
