Laparoscopic assisted percutaneous herniorrhapy in dogs using PIRS technique

Abstract

Background In the literature, no studies describe the use of laparoscopic techniques for inguinal hernia repair in canine clinical patients. The surgical technique-Percutaneous Internal Ring Suturing (PIRS) presented in this article is the world's first minimally invasive laparoscopic surgical technique for inguinal canal closure in dogs. Aim The aim of the presented study is to evaluate the possibility of employment of the laparoscopic PIRS technique in clinical practice as well as to technically evaluate its usefulness in the treatment of the inguinal hernia in dogs. The presented study describes the procedure and the results of laparoscopic treatment of 11 inguinal hernias in nine dogs (two bilateral). Methods The whole procedure is performed under camera control introduced through one umbilical trocar. The very closure of the inner inguinal ring is done with the injection needle by a small puncture over the inguinal canal with the help of which the suture material is inserted, and the canal of the operated inguinal hernia is closed. Each operated dog underwent a thorough clinical examination before surgery which was combined with ultrasound examination of the inguinal canals before, immediately after and three months after surgery. Results There was no hernia recurrence in the study period in the operated dogs and all individuals returned to full mobility immediately after recovery from anesthesia. Conclusions Due to the low invasiveness and simplicity of performance, the PIRS technique described in the study should be taken into account when choosing a treatment method for non-traumatic

“…In the technique mentioned the inner inguinal ring is closed by a percutaneous suture material using an injection needle. The entire procedure is monitored using a laparoscopic camera inserted at the umbilicus [17][18][19][20][21]. The PIRS technique through the use of extra-corporeal suturing does not require the surgeon to have advanced laparoscopic skills, which makes it technically easy [18,[21][22][23].…”

“…Treatments in the PIRS swine group were performed using the original method presented in humans by Patkowski et al [17] and in dogs by Prządka et al [18]. All endoscopic equipment used for the laparoscopic procedure with 5mm 30˚scope was manufactured by Karl Storz SE & Co. KG (Tuttlingen, Germany).…”

“…Laparoscopic treatment of inguinal hernia is now a standard in human medicine, gaining more and more popularity in the treatment of companion animals [18]. Pigs as an experimental model for human medicine are often used in the development of new methods of endoscopic surgery, including treatment of inguinal hernia [11][12][13].…”

“…Using only one trocar for optics and an 18G injection needle during the entire PIRS procedure significantly reduces the risk of accidental damage to internal organs, which sometimes occurs with the use of additional laparoscopic instruments [18]. Further advantage of the PIRS technique is the straightforward implementation, which, combined with the surgeon's only basic endoscopic surgery skills, enables its use even in field conditions.…”
