“…Yet, it is likely that this parameter strongly influences the risk of recurrence, as IAP is the main mechanical stress applied to the musculoaponeurotic wall and consequently to the scar zone. The present study reinforces the findings of a previous study, in which our team used the SP to build the pressure profile of 20 healthy volunteers [18].…”

“…The SmartPill™(SP) can be useful to evaluate IAP variations during physical standardized exercises or during daily life outside the controlled conditions of a laboratory [ 18 ]. However, the only validation study of the SmartPill™ as a tool for measuring IAP was conducted in a porcine model and concluded that IAP was underestimated compared to intra-vesical measurement [ 19 ].…”

Background: The SmartPill, a multisensor ingestible capsule, is marketed for intestinal motility disorders. It includes a pressure sensor, which could be used to study intra-abdominal pressure (IAP) variations. However, the validation data are lacking for this use. Material and Methods: An experimental study was conducted on anesthetized pigs with stepwise variations of IAP (from 0 to 15 mmHg by 3 mmHg steps) generated by laparoscopic insufflation. A SmartPill, inserted by endoscopy, provided intragastric pressure data. These data were compensated to take into account the intrabdominal temperature. They were compared to the pressure recorded by intragastric (IG) and intraperitoneal (IP) wired sensors by statistical Spearman and Bland–Altmann analysis. Results: More than 4500 pressure values for each sensor were generated on two animals. The IG pressure values obtained with the SmartPill were correlated with the IG pressure values obtained with the wired sensor (respectively, Spearman ρ coefficients 0.90 ± 0.08 and 0.72 ± 0.25; bias of −28 ± −0.3 mmHg and −29.2 ± 0.5 mmHg for pigs 1 and 2). The intragastric SmartPill values were also correlated with the IAP measured intra-peritoneally (respectively, Spearman ρ coefficients 0.49 ± 0.18 and 0.57 ± 0.30; bias of −29 ± 1 mmHg and −31 ± 0.7 mmHg for pigs 1 and 2). Conclusions: The SmartPill is a wireless and painless sensor that appears to correctly monitor IAP variations.

“…It is important to note that this article is structured as a narrative review, offering a descriptive and interpretative synthesis of the relevant literature on the topic. q DISCUSSION I ntra-abdominal pressure was considered to be involved into the development of inguinal hernias (22). Also, a positive correlation between the intra-abdominal pressure and body mass index was found (23).…”

Inguinal hernia repair is one of the most commonly performed surgical activities worldwide. Given the circumstances, understanding and identifying the risk and the protective factors is an essential step in order to prevent, diagnose and treat such a common condition. For a long time, obesity was generally considered to be a risk factor in the occurrence of an inguinal hernia. Studies have provided some unexpected data, suggesting that it might actually be a protective factor. This review aims to provide an overview on this topic, taking into account systemic aspects such as collagen distribution and metabolism. In inguinal hernia patients, the ratio between type I collagen and type III collagen is decreased, with type III collagen being responsible for the weakness of the abdominal wall. In obese patients, the extracellular matrix becomes richer in collagen, especially type I collagen, which will generate strength and stiffness. Obesity seems to be a protective factor indeed, but in order to understand the underlying mechanism and to choose the optimal surgical approach, further research is needed.

“…Some research infers the intra-abdominal pressure using an intragastric wireless sensor. The intragastric pressure, validated for estimating IAP, was assessed by an ingestible pressure sensor [ 22 ]. However, in this case, a power source, noise filter electronics, and a wireless data transmission circuit should have been connected to the sensor, which would have increased the dimensions.…”

In experimental medicine, a wide variety of sensory measurements are used. One of these is real-time precision pressure measurement. For comparative studies of the complex pathophysiology and surgical management of abdominal compartment syndrome, a multichannel pressure measurement system is essential. An important aspect is that this multichannel pressure measurement system should be able to monitor the pressure conditions in different tissue layers, and compartments, under different settings. We created a 12-channel positive–negative sensor system for simultaneous detection of pressure conditions in the abdominal cavity, the intestines, and the circulatory system. The same pressure sensor was used with different measurement ranges. In this paper, we describe the device and major experiences, advantages, and disadvantages. The sensory systems are capable of real-time, variable frequency sampling and data collection. It is also important to note that the pressure measurement system should be able to measure pressure with high sensitivity, independently of the filling medium (gas, liquid). The multichannel pressure measurement system we developed was well suited for abdominal compartment syndrome experiments and provided data for optimizing the method of negative pressure wound management. The system is also suitable for direct blood pressure measurement, making it appropriate for use in additional experimental surgical models.
