1126. Audit - intestinal surgery - removal of foreign body

Every vet at Toa Payoh Vets is required to maintain a proper record of anaesthesia and surgery in a book dedicated to each vet. I audit some cases now and then.  This case is interesting as it has been performed in a short time, using only domitor and ketamine, without isoflurane gas.

AUDIT OF ANAESTHESIA & SURGERY BY ASSOCIATE VET
Bichon, Male, 3 months
Vomiting over 5 days
Ate prayer food

Hard lump 3x2x2 cm in large intestine. Painful

ANAESTHESIA
Sep 30, 2012 (Sunday) 1.8 kg 3 months

Dom/Ket  0.07/0.09
50% given  0.04/0.05 IV

A: Injection D+K IV   3.47 pm
D: First skin incision   3.56 pm
E: Completion of skin stitching  4.11 pm
No isoflurane gas used for enterotomy

E-A  = 24 min
E-D  = 5 min

SURGERY
Around 3 cm incision. Big greenish hairy hard lump taken out.
"Apricot seed," my vet said.
3/0 monosyn appositional stitches.
I saw the intestinal wall as over 4 mm in width. Blackish edge over red inflamed patch where hard Foreign Body was lodged. Gangrene had set in. That was why dog was vomiting.
Vet has 3 years of experience. A good surgery done.

No blood test and no x-ray due to financial reasons. The owner decided on surgery on Friday evening but I advised the associate vet to wait 2 more days to strengthen the health (vomiting for past 5 days due to financial reasons, not seeking vet treatment). On Sunday afternoon, this dog was operated and today, he looks as good as gold.
Day 2  Oct 1, 2012  11.32 am, I checked the dog and took some pictures. Active. Disliked e-collar.

1125. Sunday's interesting cases - Sep 30, 2012

Sep 30, 2012

Bright sunny day
Case 1. Red-eared slider with "smaller and sunken" left eye. The husband and wife came for a review. "How many turtles have you treated?" she asked me.

"Around seven cases last year," I said. "Singaporeans seldom keep turtles to an older age like yours and there are not many."  Maybe Toa Payoh Vets get less turtle cases. Who knows?

"They release the turtles to the reservoirs," the slim wife with dark rimmed glasses said. "What type of cases you see?"

"Mostly eye problems like closed eyes. Rectal prolapse, cracked shells and not eating."

2 days ago, the husband brought the turtle for consultation as he observed the left eye sunken and smaller than the right eye. He is an observant man as his wife did not know any eye change.

I could see the haziness in the upper part of the cornea of the smaller left eye and took some images to document corneal ulceration (green flurosecein stain). Dr Daniel gave an IM injection in the back thigh muscle of an anti-inflam and antibiotics.

I advised cleaning up the turtle as it smelled fishy, giving eyedrops 3x/day and not letting the eye get wet unless eating time. After eating, wash the eye with boiled water. "Or tap water left overnight as there is chlorine in the water and that will evaporate overnight," I said.
However the husband said: "The tap water has only fluoride, not chlorine." I can't substantiate this and so said nothing.

Today, the husband was to bring the turtle for review and he did so. The turtle's left eye looked so much clearer. It is still sunken but lesser. How to prove it? It was difficult as the turtle did not permit me to take image head-on of both eyes on the reception counter. He was restless and moving. "Do it inside the consultation room after switching off the lights, as before," the husband advised. "Use ISO 3200."

"The images are not so good compared to natural light in the waiting room," I said. "I used ISO 6400 the last time." As I did not want to upset the owner, I took images inside the darkened consultation room. The turtle was calmer. The cornea looked much more transparent esp. in the 11 to 2 o'clock area where there was cloudiness 2 days ago.
Case 2.
 Shih Tzu, 1 year old, with red ear lumps in both ears but the lady in her 40s said that there was no scratching. The right ear was more painful when I palpated the vertical canal and the dog cried.
She had seen my associate vet for the past 3 times with the same problems. Antibiotics, injection and ear flushing again.
"I had spent much money in the eye ulceration treatment last time," she said to me when I advised lateral ear resection surgery. Now she trimmed the hairs around the eyes and put eye drops daily. No more eye ulcerations but this ear inflammation and pus could not be resolved since Jan 2012.
"It is usually the money matters," I said. "Ear surgery is the solution to open up the vertical canal to enable the horizontal canal to be ventilated and drained as the shih tzu's floppy ears covered up the canals 24 hours/day. But most owners will not accept the surgery due to its costs."

"How much?" she asked.
"I estimate $500 for one ear, including nursing care for around 7 days post surgery. It is just an estimate."
Now she had seen my associate vet 4 times and tried to clean the ears and give medication. The total costs and her time would be $600.
"It is just the luck of the owner," I said. "Some families have children with health problems and incur lots of medical expenses. I just have a case of a Shih Tzu dog owner who spent over $8,000 just for 5 bladder stones removal in the dog. Other Shih Tzu owners have no need to spend a cent."

Case 3.
An apricot seed inside the large intestine of the Maltese. I came back to the surgery at 3.30 pm to check whether my associate vet had operated on this Maltese. The owner had delayed operation but the dog kept vomiting and she decided on the operation on Friday. I advised against immediate operation for expediency as Saturday was the day off for my associate vet. The dog needed the IV drip and antibiotics to recover. Today, Sunday, the dog was in much better health but still vomited. My associate vet took out the apricot seed, put in interrupted appositional stitches to close up the wound. The large intestines were inflamed to 6 mm in depth of mucosa and serosa. The dog was alert and well after surgery. That was good.  
Case 4
The old Minature Schnauzer with the bloated stomach of closed pyometra came back for stitch removal as required by Dr Vanessaa. I asked Dr Daniel to remove the stitches. The pyometra surgery was done on 31 August. None of the nylon stitches were present now as it is past one month since surgery. This dog had pus in the hairy ears and dry skin problems in the forearm and body. At least she did survive the surgery as I thought the pyometra would burst if you see the images in my case studies.  



"Today, there is a white spot in the left eye," the wife said.

Hi,

I have a female jack russell coming 36 months but has yet to be spay.. Can i knw if there're any complications doing this procedure at this age? And roughly the duration and cost of it? Kindly advise, thank you.

Cheers,
J Y
 
 
 
EMAIL REPLY FROM DR SING DATED SEP 30, 2012 
 
Thank you for your email. I am Dr Sing K Y from Toa Payoh Vets.

Generally, all healthy female dogs at around 36 months of age will have no complications during or after spay.
Complications refer to anaesthetic deaths, post-op deaths, bleeding and infections. The duration of spay should be less than 30 minutes and the estimated total cost is around $250-350 at Toa Payoh Vets ( including anaesthesia, surgery, post-op injections and medication and e-collar). Pl make an appointment at 6254 3326 one day in advance.

The best time to spay is 2-3 months after the last heat (bleeding)
 

1123. VETERINARY TIPS. Take digital images of complicated post-operation cases to make you a better vet

Taking images of cases with your camerar or phone to document your cases and to do retrospective studies of your performance will make you a better veterinary surgeon. 

There may be some parts of the anatomy changes which you might have missed during the examination but images taken will be there for you to review and plan your surgery in your office.

For example, in the tough case of the Shih Tzu with perineal urine leakage after a bladder surgery by Vet 3 to remove urinary stones, an image of the swollen perineum (presumed with leaked urine from the traumatised perineal urethra) was taken by me. This is shown below:





This is one supporting evidence and there must be others to substantiate this urine leakage (ultrasound of scrotum filled with fluid), swelling of left inguinal area near where Vet 3 made a skin incision to access the bladder for urinary stone removal daily with blood-tinged fluid while the dog was catheterised with a smaller sized urinary catheter


Note that the scrotal sac is also swollen and Vet 3 had said that ultrasound revealed fluid. 

According to the owner, the whole of the lower part of the inguinal area was much swollen and that was why the dog had to be hospitalised for 8 days by Vet 3 who then recommended a 2nd urethrostomy and scrotal ablation to resolve the problem of urine leakage.  

This image was taken when the dog was seen at Toa Payoh Vets on Day 9 after Vet 3's bladder surgery which had removed all bladder stones (post-op X-rays showed no stones).

How to resolve this problem with the least cost to the owner? 

That is the tough part. Will a 2nd urethrostomy and closure of the first urethral stoma and scrotal ablation resolve the problem for once and for all?  

Vet 4 at Toa Payoh Vets was asked by the owner to neuter the dog and remove the large left inguinal swelling of the size of an egg and Vet 4 stitched up the urethral stoma (first urethrostomy done by Vet 1). 

Would this resolve the problem? Well, it did not appear to do so as the left inguinal swelling filled with blood-tinged fluid.

(I presumed it was urine leakage + blood) of around 30 ml per day for the next 4 days after Vet 4's surgery.

"Closing the urethral stoma so that the dog could pee normally from the tip of the penis is good for the dog," I said to Vet 4. "But there is the daily need to aspirate the 30 ml of blood-tinged fluid from the left inguinal area. 

"It cost the owner around $7,000 to do the past 3 surgeries to remove the bladder stone and given time, your surgical approach may work. But time means more money expenditure for the owner."

As Vet 4 had to go overseas, I took over the case and reviewed the complicated urine leakage problem. 

This involved talking to Vet 3 as to what had been done. Vet 3 said that an ultrasound revealed fluid inside the scrotum and this was not recorded in the case report as the owner was not charged. 

Ultrasound can reveal fluid in an organ but will not be able to tell whether it was urine or blood or both.

This is where the perineal swelling in this image substantiates a possible urine leakage.  It is extremely expensive to do dye test to reveal the location of the perineal urethral leakage. The surgery at Vet 3 had cost $2,000 according to the owner.

So, what's the best economical solution now? What is in the best interest of the dog? If expenses keep mounting, the dog may be put to sleep by the owner. A solution must resolve the problem.

My approach was to extend the urethra stoma which had been closed by Vet 4, do scrotal ablation, close up the inguinal sheaths and stitch the urinary catheter to the prepuce to retain it in for around 4 days to let the perineal catheter to heal. This is the theory.

In practice, this worked as the dog is now peeing normally with no blood in the urine when it came back for stitch removal on Sep 28, 2012, around 14 days after my surgery. 

Not all bladder surgery is free from complications. In this case, the perineal urethra could have been damaged. Hence the urine leaked into the perineum (causing large swellings). The urine also flowed into the scrotal sace, hence another large swelling.

1122. The vet transports the dog for an X-ray

"Surely it is not (befitting) your status to personally drive and transport the dog to get an X-ray done!" Dr Jason Teo's transport man met me at a Clinic where he had taken a cat for x-ray of the pyometra.

"My transport man had sold his van and the others were not available," I explained.
Steven pointed to an old Mercedes outside the clinic. Its engine old and smoke from the exhaust puffing out and said: "Surely, the petrol of the Mercedes would cost more than your transport cost. Why don't you just phone me?"

"I thought you just groom dogs for Jason," I did not tell him that the black Mercedes was not mine and I don't idle the engine when I park the car. It takes some time at this clinic to get the dog X-rays. In any case, I dislike polluting the environment by idling the engine unnecessarily.

"I do dog transport when I need the money," he laughed. He is an old guard in this pet business.

I find that much can be learnt just by transporting the dog for X-ray to any clinic. In one clinic, I was made most welcome by the vets. In another clinic, I would not be permitted to see any vet nor proceed past the waiting room as it has an awesome gate-keeper. So I learnt a lot by being on the ground.
   

Follow up: The 3rd sister loves and cares for the old dog

1121. Bladder stone dog goes home - 3 sisters




"Are you the sister who spoke to me by phone about the dog having kidney stones and whether an operation is necessary?" I asked the bigger of two adult ladies who came this afternoon to pick up the 12-year-old male cross-bred that looked so much like a miniature version of a Golden Retriever.



"No," she said.

"Are you the eldest of the 3 sisters?" I asked.

"No, I am the 2nd sister."

"Is the other shorter lady the youngest sister?" I asked.

"No, she is the eldest sister."

"So, the youngest sister is the most intelligent," I said. "To seek a second opinion."

"She is the one who loves the dog most," second sister said. I had talked to her by phone many times to update her of the dog but never saw her.



I put the dog on the exam table and palpated the bladder and prostate for pain. Not a whimper unlike 2 days ago.



"I need a tissue paper to wipe away the blood," 2nd sister said. The dog was so active and had pounced on her left knee and scratched 4 inches of red rash."



"This dog needs to be neutered as Vet 1 had done an ultrasound and said that the prostate was much enlarged."

"Why must he be neutered?" 2nd sister asked.

"The male hormones are produced by the testicles and they make the prostate grow bigger and it had become inflamed and infected. The enlarged prostate caused the urethra to be narrowed, making urination difficult for this dog. Bacteria from the bladder was present and could have infected the prostate. That was why it was painful 2 days ago and earlier. Vet 1 did give an anti-male-hormone injection called Tardak and advised weekly injections. Neutering would have been the alternative. Now, the dog's prostate is not inflamed or enlarged and so the dog pees normally for the last 2 days."



The dog did not pee in front of the sisters this afternoon but he had peed a few times freely in the morning.



"I have advised no bladder stone removal operation as the dog is very thin and will wait till he has difficulty in urination the next time," I said. "Although there is no crystals or struvite crystals present in his urine analysis, it does not mean he has no struvite stones. The pH is 6.0 for the past two urine analysis but bacteria is present in the urine. The bacteria in his bladder may have gone to the prostate, causing pain and inflammation of the prostate.



As the 2nd sister is an adult, she understood what a prostate is and so I need not explain further.



EXPLANATION

1. The male dog does not urine mark for the past two days. He just pees a few times in the morning when taken out for the walk. Why? This is because he was given an anti-male-hormone injection called Tardak by Vet 1 around 1 week ago and he is "feminised."



2. The urinary pH is 6.0. In struvite stone formation, the pH is usually alkaline and urease bacteria must be present. That is the norm. However, Vet 1 had recommended K/D diet and the dog was eating it. So, the urinary pH may have been affected. It is hard to say. It is too technical to explain to the sisters about alkaline urinary pH and struvite stone formation as there is information overload.



3. I advised S/D diet for the next 3 weeks as an alternative to surgery due to the high anaesthetic risks involved at present (prostate enlargement and infection, bladder infection with bacteria). This old dog much loved by this 3rd sister and it is better to build up the dog's weight and health if the bladder stone surgery is needed in the future. Neutering is advised next week as neuter is a very short 5-10-minute surgery compared to around one hour for bladder stone removal. Struvites are more common in dogs seen by me and if this S/D trial works and X-rays of the bladder are taken in a month's time, the stones would have dissolved or reduced in size, permitting urohydropropulsion. That will get rid of all the smaller stones.



4. Owners seldom comply with veterinary instructions and so much depends on educating the owner and the 3rd sister. Somebody who loves the old dog and usually it is a lady family member who cares very much for this old companion to get things done by the vet.
