We have previously explored open abdominal surgery in mice subjected to passive airflow however, operating theatres employ active airflow. Therefore, we sought an engineering solution to recapitulate the active airflow in mice. Similarly, to the passive airflow studies we investigated the influence of humidified-warm carbon dioxide (CO\n 2<\/jats:sub>\n ) on this damage in the context of active airflow. Additionally, we addressed the controversial role of surgery in exacerbating desmoidogenesis in a mouse model of familial adenomatous polyposis.\n <\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n An active airflow mouse-operating module manufactured to produce the equivalent downdraft airflow to that of a modern operating theatre was employed. We quantified mesothelial cell integrity by scanning electron microscopy (SEM) sampled from the peritoneal wall that was subjected to mechanical damage or not, with and without the delivery of humidified-warm CO\n 2<\/jats:sub>\n . To explore the role of open and laparoscopic surgery in the process of desmoidogenesis we crossed\n \n Apc\n min\/<\/jats:sup>\n <\/jats:italic>\n +<\/jats:sup>\n C57Bl\/6 mice with\n p53<\/jats:italic>\n +\/\u2212<\/jats:sup>\n mice to generate animals that developed desmoid tumors with 100% penetrance.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n One hour of active airflow generates substantial damage to peritoneal mesothelial cells and their microvilli as measured at 24\u2006h post intervention, which is significantly greater than that generated by passive airflow. Use of humidified-warm CO\n 2<\/jats:sub>\n mostly protects the mesothelium that had not experienced additional mechanical (surgical) damage at 24\u2006h. Maximal damage was evident in all treatment groups regardless of flow or use of gas. At day 10 mechanically-damaged peritoneum remains in mice but is essentially repaired in the gas-treated groups. Regarding desmoidogenesis, operating procedures did not increase the frequency of desmoid tumors but their frequency correlated with time following surgery but not age of mice.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n Active airflow generates more peritoneal damage than passive airflow and is reduced significantly by the use of humidified-warm CO\n 2<\/jats:sub>\n . Introduced peritoneal damage is largely repaired in mice by day 10 with gas. Desmoid tumor incidence is not increased substantially by surgery itself but rises over time following surgery compared to non-surgery mice.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1515\/pp-2019-0023","type":"journal-article","created":{"date-parts":[[2019,11,2]],"date-time":"2019-11-02T05:04:42Z","timestamp":1572671082000},"source":"Crossref","is-referenced-by-count":4,"title":["Modeling open surgery in mice to explore peritoneal damage, carbon dioxide humidification and desmoidogenesis"],"prefix":"10.1515","volume":"4","author":[{"given":"Timothy","family":"Chittleborough","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shienny","family":"Sampurno","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra","family":"Carpinteri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew Craig","family":"Lynch","sequence":"additional","affiliation":[{"name":"Surgery , Peter MacCallum Cancer Centre , Melbourne , Victoria , Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander Graham","family":"Heriot","sequence":"additional","affiliation":[{"name":"Surgery , Peter MacCallum Cancer Centre , Melbourne , Victoria , Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5003-0433","authenticated-orcid":false,"given":"Robert George","family":"Ramsay","sequence":"additional","affiliation":[{"name":"GI Cancer Program , Peter MacCallum Cancer Centre , 305 Grattan Street , Melbourne 3000 , Victoria , Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2019,11,2]]},"reference":[{"key":"2025120909222921794_j_pp-2019-0023_ref_001_w2aab3b7b4b1b6b1ab1b6b1Aa","doi-asserted-by":"crossref","unstructured":"Dharan S, Pittet D.
