Gasless Laparoscopic Anatomy and Renal Biopsy of the Kidney in the Standing Mare

Abstract

SUMMARY:The current study aimed to provide the topography and renal biopsy of the standing mare kidneys by laparoscopy w ithout CO 2 insufflation and to compare between the use of biopsy needle and forceps. Five clinically healthy adult nonpregnant mares weighing 250-300 Kg and aging 7-9 years were used in the current work. The gasless laparoscopic renal biopsy appeared simple, safe, reliable, minimal invasive, timesaving and economical technique. The parallel biopsy portals provided easy and accessible biopsy procedure than dorsal or ventral portals. The biopsies taken from the lateral surface were less hemorrhagic than those taken from the caudal pole. This study recommended the laparoscopic forceps because the biopsy forceps provided satisfactory and representative specimens with minimal hemorrhage than Tru-cut needle.

Gasless laparoscopic renal biopsy in canine cadavers: a preclinical study

“…The gasless laparoscopic approach avoids hemodynamic overload ( Shoman et al, 2020 ), allowing the use of traditional instruments and the performance of complex surgeries and maneuvers ( Andersson et al, 2003 ; Chiu et al, 1996 ). Specific reports of performing renal biopsies using gasless laparoscopy in animals are limited ( Chiesa et al, 2009 ; Kassem et al, 2014 ). These studies have considered the relatively simple, safe, and fast procedure with adequate visualization and have obtained quality samples.…”
