The consumer wearables boom has spawned a new generation of wrist- or waistband-mounted sensors that stream step count, heart-rate and temperature data continuously, creating an opportunity for data-driven early-warning strategies. No previous systematic review has focused exclusively on colorectal surgery. Methods: Three databases (PubMed, Embase, and Scopus) were searched (inception\u20141 May 2025) for prospective or retrospective studies that used a consumer-grade or medical-grade wearable to collect objective physical-activity or vital-sign data during the peri-operative period of elective colorectal resection. Primary outcomes were postoperative complication rates, length-of-stay (LOS) and 30-day readmission. Two reviewers screened records, extracted data and performed risk-of-bias appraisals with ROBINS-I or RoB 2. Narrative synthesis was adopted because of the heterogeneity in devices, recording windows and outcome definitions. Results: Nine studies (n = 778 patients) met eligibility: one randomised controlled trial (RCT), seven prospective cohort studies and one retrospective analysis. Five studies relied on step-count metrics alone; four combined step-count with heart-rate or skin-temperature streams. Median wear time was 6 d (range 2\u201330). Higher day-1 step count (\u22651000 steps) was associated with shorter LOS (odds ratio 0.63; 95% CI 0.45\u20130.84). Smart-band\u2013augmented ERAS pathways shortened protocol-defined LOS by 1.1 d. Pre-operative inactivity (&lt;5000 steps\u00b7day\u22121) and low \u201creturn-to-baseline\u201d activity on the day before discharge independently predicted any complication (OR 0.39) and 30-day readmission (OR 0.60 per 10% increment). A prospective 101-patient study that paired pedometer-recorded ambulation with daily lung-ultrasound scores found fewer pulmonary complications when patients walked further (Spearman r = \u20130.36, p &lt; 0.05). Conclusions: Continuous, patient-worn sensors are feasible and yield clinically meaningful data after colorectal surgery. Early postoperative step-count trajectories and activity-derived recovery indices correlate with LOS, complications and readmission, supporting their incorporation into digital ERAS dashboards. Standardised outcome definitions, open algorithms for signal processing and multicentre validation are now required.<\/jats:p>","DOI":"10.3390\/diagnostics15172194","type":"journal-article","created":{"date-parts":[[2025,8,29]],"date-time":"2025-08-29T12:25:57Z","timestamp":1756470357000},"page":"2194","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Continuous Wearable-Sensor Monitoring After Colorectal Surgery: A Systematic Review of Clinical Outcomes and Predictive Analytics"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0497-0405","authenticated-orcid":false,"given":"Calin","family":"Muntean","sequence":"first","affiliation":[{"name":"Medical Informatics and Biostatistics, Department III-Functional Sciences, \u201cVictor Babe\u015f\u201d University of Medicine and Pharmacy Timi\u015foara, Eftimie Murgu Square No. 2, 300041 Timi\u015foara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-8647-1003","authenticated-orcid":false,"given":"Vasile","family":"Gaborean","sequence":"additional","affiliation":[{"name":"Thoracic Surgery Research Center, \u201cVictor Babe\u015f\u201d University of Medicine and Pharmacy Timi\u015foara, Eftimie Murgu Square No. 2, 300041 Timi\u015foara, Romania"},{"name":"Department of Surgical Semiology, Faculty of Medicine, \u201cVictor Babe\u015f\u201d University of Medicine and Pharmacy Timi\u015foara, Eftimie Murgu Square No. 2, 300041 Timi\u015foara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alaviana Monique","family":"Faur","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, \u201cVictor Babe\u015f\u201d University of Medicine and Pharmacy Timi\u015foara, 300041 Timi\u015foara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6451-7461","authenticated-orcid":false,"given":"Ionut Flaviu","family":"Faur","sequence":"additional","affiliation":[{"name":"X Department of General Surgery, \u201cVictor Babe\u015f\u201d University of Medicine and Pharmacy Timi\u015foara, 300041 Timisoara, Romania"},{"name":"2nd Surgery Clinic, Timisoara Emergency County Hospital, 300723 Timi\u015foara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4348-5469","authenticated-orcid":false,"given":"C\u0103t\u0103lin","family":"Prodan-B\u0103rbulescu","sequence":"additional","affiliation":[{"name":"X Department of General Surgery, \u201cVictor Babe\u015f\u201d University of Medicine and Pharmacy Timi\u015foara, 300041 Timisoara, Romania"},{"name":"2nd Surgery Clinic, Timisoara Emergency County Hospital, 300723 Timi\u015foara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3277-1198","authenticated-orcid":false,"given":"Catalin Vladut Ionut","family":"Feier","sequence":"additional","affiliation":[{"name":"Abdominal Surgery and Phlebology Research Center, \u201cVictor Babe\u015f\u201d University of Medicine and Pharmacy Timi\u015foara, 300041 Timi\u015foara, Romania"},{"name":"First Surgery Clinic, \u201cPius Brinzeu\u201d Clinical Emergency Hospital, 300723 Timi\u015foara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1304","DOI":"10.1093\/bjs\/znab323","article-title":"Mobile health technology for remote home monitoring after surgery: A meta-analysis","volume":"108","author":"Dawes","year":"2021","journal-title":"Br.
