Laparoscopic correction of experimentally induced diaphragmatic rupture in dogs

Abstract

PURPOSE:To describe the dog as a model for studying laparoscopic correction of experimental diaphragmatic ruptures. METHODS:Five male dogs were used in this study. Under laparoscopic approach, a defect of 7cm was created on the left ventral insertion of the diaphragm. Fourteen days after this procedure, the abdomen was explored using laparoscopic access and the diaphragmatic defect was corrected with intracorporeal suture. The dislocated organs, surgical time, and suturing time were recorded. Analgesia and clinical condition were monitored during the postoperative period. RESULTS:All animals recovered well from the diaphragmatic rupture creation. After 14 days, abdominal organs (liver, spleen, omentum and/or intestine) were found inside the thoracic cavity in all animals. It was possible to reposition the organs and suture the defect by laparoscopic access in three animals. These animals showed excellent postoperative recovery. It was not possible to reposition the liver safely when it was friable. CONCLUSIONS:Laparoscopic creation of diaphragmatic rupture in dogs is feasible. Dogs are a good model for training and studying the correction of experimentally created diaphragmatic rupture by the laparoscopic approach. A friable liver is a complicating factor that should be taken into account. Animals submitted to laparoscopic correction showed excellent postoperative recovery.

Use of a new device for gasless endosurgery in a laparoscopic diaphragmatic hernia repair ex vivo canine model: A pre‐clinical study

“…The time required for laparoscopic diaphragm reconstruction was similar (Beck et al., 2004 ; Brun et al., 2010 ) or longer (Souza et al., 2015 ) than described in previous studies; however, it is not possible to directly compare these results due to the visible methodological differences between the models, including the type of diaphragm defect, access, and reconstruction techniques used. Hernia repair (step T3) was longer in the GS group than in the mesh group.…”

“…The use of three access ports for laparoscopic reconstruction of diaphragmatic hernias has been previously described (Beck et al., 2004 ; Brun, 2017 , 2010 ; Monnet & Fransson, 2015 ; Souza et al., 2015 ). In this study, three portal accesses in five configurations were used for laparoscopic hernia repair.…”

“…This effect can be considerably reduced with the present device by applying traction sutures close to the costal edge on the approached flank. The use of three access ports for laparoscopic reconstruction of diaphragmatic hernias has been previously described (Beck et al, 2004;Brun, 2017Brun, , 2010Monnet & Fransson, 2015;Souza et al, 2015). In this study, three portal accesses in five configurations were used for laparoscopic hernia repair.…”

Sudden death caused by diaphragmatic rupture following rib fracture in a female sika deer (Cervus nippon) at a zoo

“…Several reports have documented diaphragmatic rupture in animals such as koalas [5] and a cat [13], caused by road traffic accidents, as well as in foals [12] and horses [11] with or without history of injury. A recent study also documented the laparoscopic correction of experimentally induced diaphragmatic rupture in dogs [15]. Here, we report a rare case of diaphragmatic rupture caused by rib fracture in a sika deer during exhibition at a zoo.…”

Surgical technique and complications associated with laparoscopic pleuroperitoneal diaphragmatic herniorrhaphy in a dog

“…More recently, however, laparoscopic and thoracoscopic techniques for herniorrhaphy have gained popularity due to the well-documented benefits of minimally invasive surgery. [9][10][11][12][13][14] The following case report describes the clinical features, imaging findings, surgical approach and outcome of an elderly dog that underwent laparoscopic herniorrhaphy to repair an incidentally diagnosed pleuroperitoneal hernia.…”
