{"abstract":[{"text":"Background: Inadequate suture tension is a risk factor for the failure of laparotomy closure.\r\nSuture tension dynamics in the abdominal wall are still obscure due to the lack of\r\nmeasuring devices. To answer the questions if intra-abdominal hypertension (IAH) influences\r\nsuture tension in midline laparotomies and if IAH leads to a permanent loss of\r\nsuture tension, microsensors were applied in a porcine model of IAH.\r\nMaterial and methods: Microsensors measuring suture tension “on the thread” with a frequency\r\nof 1/s were developed and implanted in the suture lines of midline laparotomies in\r\nfour pigs. During a 23-h experiment under general anesthesia, two intervals of IAH (30 mm\r\nHg) were applied, interrupted by a 3-h interval without elevated intra-abdominal pressure.\r\nResults: All sensors showed an immediate and reproducible response to changes of intraabdominal\r\npressure. The two 9-h periods of IAH resulted in a significant elevation of suture\r\ntension (P¼0.003 and P¼0.0009, respectively). Reducing the IAH lead to a significant loss\r\nof suture tension (P¼0.0005andP¼0.0001, respectively). After the second interval with IAH, a\r\ncomplete loss of mean suture tension was observed. A statistically significant “recovery” of\r\nsuture tension in the interval between the two phases with IAH was not observed.\r\nConclusions: Intervals with elevated intra-abdominal pressure have a direct influence on\r\nsuture tension in midline laparotomy wounds. Intervals with IAH lead to a significant loss\r\nof suture tension in the suture line and to a complete loss of mean suture tension at the\r\nend of this experiment. A subsequent gaping of the fascia might contribute to either acute\r\nor chronic failure of laparotomy closure","lang":"eng"}],"language":[{"iso":"eng"}],"volume":233,"_id":"3229","status":"public","publication_status":"published","year":"2019","type":"journal_article","title":"Influence of Elevated Intra-abdominal Pressure on Suture Tension Dynamics in a Porcine Model","citation":{"short":"A.
