A technical note on low cost rat laparoscopy an initial experience

Abstract Purpose: To evaluate a novel and adapted low-cost set model for laparoscopic surgery in rats. Methods: Nine Wistar rats underwent two different laparoscopic procedures, splenectomy (n=3) and distal pancreatectomy with splenectomy (n = 6), after assembling a low-cost set replacing the conventional one (monitor, micro camera, image processor, light source, laparoscope and insufflator). The new set included an Android Tablet 10.5 ", a 5mm USB Endoscope and semiautomatic sphygmomanometer monitor. Results: The same surgeon performed the laparoscopic procedures. Total surgical time ranged from 36 to 60 minutes with a mean of 45.8 minutes. Three rats died during the distal pancreatic and splenectomy procedure (33.3%), due to respiratory failure (n = 1), uncontrolled abdominal hemorrhage (n=1) and iatrogenic gastric perforation (n = 1). We followed the other six rats (66.6%) for seven days with no further evidence of complications. Conclusions: The laparoscopic partial pancreatectomy and splenectomy can be performed with the novel low-cost set assembled in the present experimental study. Both specific training and skills development are required to validate more advanced laparoscopic procedures and achieve a desirable outcome.
