Safety and efficacy of absorbable and non-absorbable fixation systems for intraperitoneal mesh fixation: an experimental study in swine
ConclusionCapsure ™ fixation system provided higher peel strength that the other tested devices in our swine model of intraperitoneal mesh fixation. Our findings generate the hypothesis that this type of fixation may be superior in a clinical setting. Clinical trials with long-term follow-up are required to assess the safety and efficacy of mesh fixation systems in hernia surgery.

Effect of three different bariatric obesity surgery procedures on nutrient and energy digestibility using a swine experimental model
Morbid obesity is a worldwide health concern that compromises life quality and health status of obese human subjects. Bariatric surgery for treating morbid obesity remains as one of the best alternatives to promote excess weight loss and to reduce co-morbidities. We have not found studies reporting nutrients and energy balance considering digestibility trials in humans following surgery. The purpose of this study was to determine protein, lipid, fiber, energy, calcium, and phosphorous digestibility in a swine model that underwent ileal transposition (IT), sleeve gastrectomy with ileal transposition (SGIT), Roux-en-Y gastri...

Inhalation anesthesia induced by isoflurane alters penicillin disposition in swine tissues
Twelve healthy swine were dosed with penicillin G intramuscularly. Fluids and tissues samples were collected at the end of two periods of general anesthesia, performed 24 h apart. Tissue samples were collected by minimally invasive laparoscopy under general anesthesia at 8 and 28 h postdose. Four nonanesthetized, penicillin‐treated pigs were euthanized at 8 h postdose, and a second set of four similarly treated control pigs were sacrificed 28 h postdose. Liver penicillin tissue concentrations from animals that underwent anesthesia and laparoscopic tissue collection had tissue concentrations that were higher than nona...

Bigger is better: Comparison of alternative devices for tension hemopneumothorax and pulseless electrical activity in a Yorkshire swine model
CONCLUSIONS: While mVN performed comparably to 14G AC, both have unacceptable failure rates. Ten-gauge AC and LT performed superiorly in both t-H/PTX and PEA. We believe there is now ample evidence supporting replacement of the 14G AC with 10G AC in current treatment recommendations.

Development of a nitinol-actuated surgical instrument for laparoscopic renal denervation: feasibility test in a swine survival model.
Conclusion: We developed a novel nitinol-actuated surgical instrument with which to perform laparoscopic renal denervation. The feasibility of our device was verified using thermomechanical analyses of nitinol, and assessments of mechanical and physiological performance. Our device could be used in other laparoscopic procedures that require large degrees of freedom while restricting to trocar size. PMID: 32552042 [PubMed - in process]

New 5-mm laparoscopic pneumodissector device to improve laparoscopic dissection: an experimental study of its safety in a swine model
ConclusionsThe 5-mm laparoscopic PD appears to be free from CO2 GE risk when consecutive bursts of high-pressure CO2 are delivered for 3 –5 s with a flow rate of 10 mL/s.

Optimal pressure of abdominal gas insufflation for bleeding control in a severe swine splenic injury model
Conclusions: All target peritoneal pressures were easily and reliably achieved with the portable CO2 insufflator. Abdominal gas insufflation produced optimal bleeding control at 20 mm Hg. This technology could be used in a pre-hospital setting to control otherwise lethal hemorrhage at pressures typically used for standard laparoscopic surgery and proven to be safe.

Single-Session Baseline Virtual Reality Simulator Scores Predict Technical Performance for Laparoscopic Colectomy: A Study in the Swine Model
Virtual reality (VR) simulation helps reducing the learning curve of laparoscopic colectomy. Moreover, it may be used to ascertain surgeons’ pretraining skills. It was aimed to establish predictive validity of specific parameters gathered during VR simulation training on sigmoid colectomy and whether simulator parameters correlate with technical performance during the same operation in a swine model.

Efficacy and safety of a new single-port model for appendectomy: Experimental study on swine
Conclusion: The surgical technique used with the single port showed no differences in safety and efficacy. Though it does require more CO2use, its working dynamics did not lead to increased operative times. The results were similar between the two surgeons in the study, suggesting that they can be reproduced.

A comparison of Selective Aortic Arch Perfusion and Resuscitative Endovascular Balloon Occlusion of the Aorta for the management of hemorrhage-induced traumatic cardiac arrest: A translational model in large swine
by Ed B. G. Barnard, James E. Manning, Jason E. Smith, Jason M. Rall, Jennifer M. Cox, James D. Ross BackgroundSurvival rates remain low after hemorrhage-induced traumatic cardiac arrest (TCA). Noncompressible torso hemorrhage (NCTH) is a major cause of potentially survivable trauma death. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) at the thoracic aorta (Zone 1) can limit subdiaphragmatic blood loss and allow for IV fluid resuscitation when intrinsic cardiac activity is still present. Selective Aortic Arch Perfusion (SAAP) combines thoracic aortic balloon hemorrhage control with intra-aortic oxygenat...

Hydrogen-rich saline protects against hepatic injury induced by ischemia-reperfusion and laparoscopic hepatectomy in swine
ConclusionsHRS treatment may exert a protective effect against I/R and hepatectomy-induced hepatic damage by reducing oxidative stress, suppressing the inflammatory response and promoting liver regeneration.

Multiphase preclinical assessment of a novel device to locate unintentionally retained surgical sharps: a proof-of-concept study
CONCLUSIONS: The use of MSF in this study's RSS models facilitated the determination of presence and localization of RSS as shown by the increased rate of identification of a needle, decreased time to identification and higher accuracy in determining the presence of a needle. This device may be used in conjunction with radiography as it gives live visual and auditory feedback for users during the search for RSS.PMID:37101230 | DOI:10.1186/s13037-023-00359-8
