Suture tension has an influence on the quality of tissue regeneration. No sensors are available to register suture tension dynamics.\r\nMethods: In a series of animal experiments, the effects of suture tension on the ultrastructure of the healing incision were examined. Surgeons´ ability to suture with target tension was tested. An implantable sensor and data logger were constructed and tested in sutures closing midline laparotomies in pigs. The influence of elevated intra-abdominal pressure on suture tension dynamics was evaluated. \r\nResults: High suture tension has a negative influence on the regeneration of laparotomy incisions. Running sutures for laparotomy closure lose 45 % of their initial tension during 23 hours. Intermittent elevation of intra-abdominal pressure to 30 mm Hg leads to a near total loss of suture tension after 23 hours.\r\nConclusion: Surgeons are not able to control and reproduce suture tension. Suture tension dynamics can be measured in vivo by the sensor developed. Further research is needed to define a tissue specific suture tension optimum to reduce the incidence of complications after laparotomy. Techniques for laparotomy closure need to be modified.","lang":"eng"}],"issue":"6","date_created":"2023-06-15T13:09:14Z","date_updated":"2023-08-18T11:52:28Z","year":"2018","publication_status":"published","author":[{"first_name":"Jörg","last_name":"Höer","full_name":"Höer, Jörg"},{"full_name":"Wetter, Oliver Utz","first_name":"Oliver Utz","last_name":"Wetter","id":"206920","orcid":"0000-0003-3223-5050"}],"status":"public","oa":"1","_id":"3230","article_number":"1729","keyword":["suture tension","incisional hernia","laparotomy closure","laparotomy","implantable sensor","tactile control","surgical complications","surgical technique"],"citation":{"chicago":"Höer, Jörg, and Oliver Utz Wetter. “Miniaturized Sensors Registering the Long-Term Course of Suture Tension In Vivo under Varying Intra-Abdominal Pressure.” <i>Sensors</i> 18, no. 6 (2018). <a href=\"https://doi.org/10.3390/s18061729\">https://doi.org/10.3390/s18061729</a>.","alphadin":"<span style=\"font-variant:small-caps;\">Höer, Jörg</span> ; <span style=\"font-variant:small-caps;\">Wetter, Oliver Utz</span>: Miniaturized Sensors Registering the Long-Term Course of Suture Tension In Vivo under Varying Intra-Abdominal Pressure.
