Intra Abdominal Pressure

The proposed clinical study protocol is intended to establish the safety, utility, and reliability of using a pressure-sensing capsule present in a patient's gastrointestinal tract for monitoring intraabdominal pressure (IAP). Monitoring IAP in critically ill patients is common in patients admitted to the ICU following a wide variety of surgical interventions. It has been reported that approximately 50% of critically ill patients will develop intraabdominal hypertension (IAH; defined as an IAP \>12 mmHg) while in the ICU, which can be life-threatening due to complications resulting from organ dysfunction, organ failure, impaired ventilation and hemodynamic instability. When IAH is persistent and elevated above 20 mmHg the condition is identified as "Abdominal Compartment Syndrome (ACS)", which necessitates close monitoring of patients with IAH in order to reduce the development of ACS. IAP measurements based on technologies employing the bladder, gastric, inferior vena cava, rectal, vaginal and direct intraperitoneal placements have been reported for assessing IAP. However, the gold standard method for monitoring IAP is the use of an intravesical (bladder) Foley catheter manometric technique. PressureDOT® (Dotspace Inc.) is the investigational pressure-sensing capsule that will be assessed in a parallel device clinical study protocol performed in the same patient.

This study investigates the development of intra-abdominal hypertension and compartment syndrome in patients undergoing elective pancreatic procedures. Main objective is to determine the proportion of patients after pancreatic operation who develop elevated intra-abdominal pressure and assess its association with postoperative complication rates. Another goal of the study is to compare open versus robotic pancreatic procedures regarding the occurrence of intra-abdominal hypertension and abdominal compartment syndrome.
