Abstract
Objective: To compare periportal gas leakage of 3 laparoscopic cannulas with and without a Rumel suture.
Methods: This was a descriptive canine cadaveric (n = 10) study performed from October 28 to 29, 2023. Five portal configurations were compared: a smooth (S) and threaded (T) cannula with and without a Rumel suture (SR and TR, respectively) and a balloon (B) cannula. Each configuration was inserted once each on midline and paramedian, the abdomen was insufflated to 10 mm Hg, and the cannula was manipulated for 2 minutes. Gas leakage was recorded by using a soap bubble test and the duration of insufflation (seconds).
Results: Regardless of location, SR and TR had the fewest number of leaks and duration of insufflation. When comparing midline portal locations, there were no demonstrable differences in duration of insufflation between portal configurations. When comparing the estimated difference in duration of insufflation for paramedian portal locations, SR had a lower duration of insufflation compared to T by 67.0 seconds and S by 46.2 seconds, and TR had a lower duration of insufflation compared to T by 66.5 seconds and S by 45.7 seconds. Between midline and paramedian, the S configuration had a statistically significant decrease in duration of insufflation on midline compared to paramedian by 30.4 seconds. The T configuration had a significantly lower duration of insufflation on midline compared to paramedian by 51.1 seconds.
Conclusions: Gas leakage varies between portals, and adding a Rumel suture decreased gas leakage.
Clinical relevance: Surrounding stainless steel entry portals with a Rumel suture could help minimize insufflation leakage of the cannula.
目的：比较Rumel缝合与不缝合3条腹腔镜插管门静脉周围气体泄漏的临床疗效。方法：这是一项描述性犬尸体研究（n = 10），于2023年10月28日至29日进行。比较了五种门静脉结构：光滑(S)和螺纹(T)插管，分别采用和不采用Rumel缝合（SR和TR），球囊(B)插管。每组分别在中线和旁线各插入1次，腹部充气至10 mm Hg，操作2分钟。使用肥皂泡测试和充气持续时间（秒）记录气体泄漏。结果：无论位置如何，SR和TR的泄漏次数最少，充气时间最短。当比较中线传送门位置时，在传送门配置之间的充气持续时间上没有明显的差异。当比较门静脉旁脉位置的充气持续时间的估计差异时，SR的充气持续时间比T低67.0秒，S低46.2秒，TR的充气持续时间比T低66.5秒，S低45.7秒。在中线和旁线之间，S组在中线的充气持续时间比旁线组减少了30.4秒，具有统计学意义。T型组在中线处的充气持续时间比旁位组明显缩短51.1秒。结论：不同门静脉间气体泄漏情况不同，采用Rumel缝合可减少气体泄漏。临床意义：用Rumel缝线围住不锈钢入口可以减少插管的充气式渗漏。
期刊介绍：
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
