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

Laparoscopic Treatment of Peritoneal-Pericardial Diaphragmatic Hernia

Laparoscopic herniorrhaphy provides a feasible minimally invasive treatment option for dogs with peritoneal-pericardial hernias with careful case selection. This article describes the techniques, instrumentation, and challenges associated with laparoscopic peritoneal-pericardial diaphragmatic hernia repair.

Gasless laparoscopic renal biopsy in canine cadavers: a preclinical study

In this study we aimed to analyze the feasibility of the gasless renal biopsy technique in canine cadavers. The cadavers were randomly divided into two groups: laparoscopic GCG, in which gasless laparoscopy was performed and GCP, laparoscopy with pneumoperitoneum was performed. The procedures were randomly performed on the right and left kidneys. The total surgical time, procedural steps, and intraoperative complications were recorded. The degree of difficulty of the surgical approaches was evaluated by the surgeon, assistant, and external evaluators. Renal samples were evaluated for quality, number of glomeruli, and proportion of renal cortex. The total operative time was higher in the GCG group than in the GCP group (p < 0.01). Additionally, positioning of the second portal and platform positioning took longer than the other steps. The surgical groups differed from each other in the Likert scale values for almost all the parameters regarding the difficulty of the surgical approaches (p < 0.05), with higher scores in the GCG group than in the GCP group. Based on the video recordings, the GCP group had higher scores than the GCG group for degrees of difficulty of the approach (p < 0.05). Renal histological parameters were similar between the surgical groups and surgical sides. Our study findings indicate that the proposed gasless renal biopsy technique is feasible. The longer operative time and technical difficulties in the gasless approach did not affect the quality of the renal specimens.

Laparoscopic extra-abdominal transfascial suturing technique for diaphragmatic rupture repair in a cat

OBJECTIVE

To describe the technique, complications, and outcome of the laparoscopic extra-abdominal transfascial suturing method for diaphragmatic rupture repair in a cat.

STUDY DESIGN

Case report.

ANIMALS

A 10 year old, female domestic shorthair cat.

METHODS

An acute traumatic diaphragmatic rupture was diagnosed in a cat. Following initial stabilization, 3-port laparoscopic surgery was performed. After the laparoscopic reduction of herniating organs, a circumferential diaphragmatic tear was diagnosed, which was repaired using a multiple extra-abdominal transfascial suture technique. The total surgical time was 50 min with no intraoperative complications encountered.

RESULTS

The successful procedure was confirmed by normalization of chest radiography, clinical signs, and blood gas analysis in the perioperative and postoperative periods. Mild skin irritation occurred 3 weeks after surgery but was resolved following the removal of sutures. The cat recovered well without major complications; the final reexamination was performed 3 months postoperatively.

CONCLUSION

The laparoscopic extra-abdominal transfascial suturing technique appears to be a feasible, and effective technique for feline diaphragmatic circumferential rupture repair. This technique may be an alternative option to intracorporeal suturing for diaphragmatic rupture treatment in the cat.
