Keyhole & Endoscopic Surgery Videos

A short snippet of the crucial part of the keyhole spay procedure in bitches.

This bronchoscopy video shows an ear of barley trapped in a 2yr old Springer Spaniel’s right lung bronchus. The dog presented with sudden onset coughing after a walk but was not referred for 2 weeks. Whilst sometimes it is possible to remove the foreign  body via bronchoscopy it was not possible in this case as the barley was trapped and a lung lobectomy was performed.

This cystoscopic view clearly shows the urine passing through a ureteral opening in the wall of the bladder. Cystoscopy is a very useful non invasive tool to check for ectopic ureters, bladder stones, and to take biopsies of the bladder wall to diagnose inflammatory and tumourous conditions. Whilst a rigid endoscope can be used for female dogs a 3mm flexible urethroscope is used in male dogs to reach the bladder.

This video is of a retrograde nasopharyngoscopy and shows a severe nasopharyngeal lymphoid hyperplasia. This is commonly seen in cats with prolonged sneezing or a nidus of chronic inflammation and should not be confused with a tumour. It will respond to the appropriate treatment {or removal of the inflammatory cause such as a grass seed foreign body}.

This video shows the laparoscopic assisted removal of multiple small bladder stones. The bladder is temporarily attached to the ventral abdomen via a keyhole approach {to prevent urine leakage} and an incision is made into it. This enables a rigid endoscope to enter and either remove large stones via forceps in the biopsy channel or, as in this case, to suck up small stones with a urinary catheter placed alongside the endoscope. A urethral catheter can be flushed to ensure all stones have been removed before closing the bladder incision, freeing it from the abdominal wall and closing the keyhole routinely.

Laparoscopic Liver biopsy: The edge of the liver is grasped with biopsy forceps and held for 1 minute to allow some clotting and sealing to occur. The biopsy is taken and there is a small amount of haemorrhage. A palpation probe is then used to put pressure on the bleeding liver for a minute or two to check that the haemorrhage stops. Each of the markings on the palpation probe are 1cm long giving an indication of the biopsy size and the amount of bleeding. A blood clotting profile is taken before performing liver biopsies in this way.

This video shows a renal (kidney) biopsy. A palpation probe is used to hold the kidney in place. A Trucut biopsy needle is advanced into the abdomen {a small skin incision is made with a scalpel first}. A biopsy is carefully taken to sample the renal cortex and not the medulla. The palpation probe is placed over the biopsy site and held there for a couple of minutes to allow clotting to occur. Several biopsies may be taken from each kidney in this way. Some samples are sent for histopathology and one for bacterial culture and sensitivity if pyelonephritis is suspected.
