44. Medial entropion surgery in the Shih Tzu

Saturday Feb 6, 2010 was my day off. However, a person wanted a meeting. So, I was flexible and took the time to meet the 3 young vets and had an interesting discussion with them and at the same time educate myself regarding the veterinary industry and trends.

One of the problems of young vets is the prospective clients' remark: "You look so young...can you perform the surgery (e.g.repair the bite wounds)?"

Well, this is a common remark and applies even to medical surgeons. Last year, I was at the Singapore General Hospital for an operation to be done by Dr Foo Chee Liam, an experienced surgeon in his late 50s and an old friend. All prospective patients will be comforted by the appearance of his grey hairs. They testify to his abundant surgical experience over the years.

His assistant, a young surgeon known as "The Registrar" attended to me in the administrative matters. I asked her how's her posting as we walked to another section to make the booking and she said to me: "Singaporeans look at me and query whether I am capable of doing their operation." I was not surprised at her comments as Singaporeans say the same thing to newly minted veterinary surgeons too.

How should one reply to such queries? It will be difficult unless one is a show man and produce testimonials. The business of surgery is serious and is not a theatre. I guess, the young ones who don't have senior vets in the practice have to take such remarks in their stride and assure the prospective client that his dog is in good hands. "Such remarks are made about the young vets in established vet practices in Singapore," I told the 3 young vets. "All vets will have to go through such challenging remarks."

Other than real people in this real world, is there another invisible world supervising us? I ask this question because I had this 10-year-old Shih Tzu with corneal ulcers, acute conjunctivitis and pus in his left eye. A 1-year-old Shih Tzu had come in 3 days ago for medial entropion surgery. This 10-year-old Shih Tzu was my answer to "what happens if there was no medial entropion surgery done for the Shih Tzu?" Where can I get a recent photograph to illustrate my medial entropion surgery?

Well, you can call it a coincidence. I have had 3 Shih Tzus recently. But the 10-year-old Shih Tzu was presented with corneal ulcerations and black eye bags due to many years of irritation from excessive tear production and rubbing of the eyes. All these could be avoided if the owner had got a medial canthoplasty and nasal fold excision. "I don't know there is such a surgery," the lady owner told me. It is a surgery seldom mentioned by vets in any case.

The following pictures explain the surgery. Goto www.toapayohvets.com for the pictures.

43. Blood in the urine of an older male dog

"Around 8 months ago, Vet 1 checked the bladder with his hand and said that he could feel no urinary stones," the young man said to me. "So he prescribed medication. My dog stopped passing blood in the urine for 2 months only."

"Why didn't Vet 1 X-ray the dog?" I asked. The young man who wanted to be a Food and Beverage entrepreneur said, "Vet 1 felt the bladder and since there was no stones, there was no need to X-ray the bladder. He even refer me to Vet 2 who had better X-ray and equipment." Vet 1's X-rays did give erratic quality and that might be why he did not take the X-ray. Most likely, to remain price-competitive with Vet 2, he would rather not increase his fees due to X-ray charges.

This amenable young man was a good conversationalist. He joked with me, pointing to his tummy and saying: "I enjoy eating food as you can see." Yes, I could see he looked very much like a successful chef with the proportions and size to prove he loves good food.

The owner then sought a second opinion from Vet 2.
"Vet 2 did an ultrasound scan and said there were no urinary stones. I got the medication and the dog stopped passing blood in the urine for 2 months. So, I asked Vet 2 to do an X-ray and there were urinary stones."

"why didn't you ask Vet 2 perform the operation?" I guessed the vet fees would be it more expensive as it was a much bigger set up with vets. Price has always been important in this period of recession and job losses.

But the young man said: "Two of my dogs died at Vet 2. One of them was old. The other one died on the operating table. So, I do not want my dog to be operated there."

This survey showed that this dog owner does not forgive or forget the death of his dog on the operating table. All vets will get pet deaths on the operating table as not all surgical cases are in excellent health.


Urinary sand and stones in the bladder and penile urethra. Actual stones are placed on top of the X-ray for comparison
Abundant fine urinary sand is found in the bladder during surgery. The sand can be seen on X-ray but it is not so clear


Day 2 after removal of urinary stones
Well-formed sharp urinary stones inside the penile urethra
I did this survey to help me understand the owner's point of view as many owners do hop between vets. Dogs are family members and a large number of dog owners in Singapore and all over the world is very worried about deaths during anaesthesia. This survey shows that the owner never really forgives such episodes.

Fortunately, the old dog operated by my Associate Dr Jason Teo was much alive during and after the surgery. Otherwise it would be another black list in this young man's book of vets to avoid.

VETERINARY TIP
In retrospect, during the surgery in Feb 2010, this old dog had abundant amount of urinary sand inside the bladder. This urinary calculi was obvious in the excellent X-ray taken by Vet 2 but the contrast using air inside the bladder could not be made due to large obstruction by stones in the penile urethra. Bladder palpation will not reveal the presence of urinary sand.

Urinary stones. Which surgical approach?

42. Urinary stone removal - Urethrostomy or Cystostomy?

URETHOSTOMY METHOD
The surgical approach depends on the vet.
I remember a Chihuahua owner from Toa Payoh some years ago. He preferred an older vet to handle his Chihuahua's urinary stone obstruction behind the os penis after getting a diagnosis from me. Such situations happen to all vets and so I was not offended. The older vet did a urethrostomy behind the os penis. Problem solved. However, the owner did not like the post-operation complications, saying that the dog "leaked urine" all over the apartment after the surgery.

I don't know whether this male dog was urine-marking or not as I did not make further queries. He wanted euthanasia. Vets do urethrosomy if the bladder has no stones. But should the dog continues urine-marking, the urine just "leaks" everywhere.

If there are no stones inside the bladder, most vets will use the urethrostomy method. It is logical. However, in the above case, it had an unhappy ending as the owner got the dog euthanased for dirtying the apartment. Would a cystostomy approach as done below save this Chihuahua's life?







CYSTOSTOMY METHOD
Yorkshire Terrier, Male, 9 years. 3.6 kg 39.4C
Urethral obstruction.
X-rays showed urinary stones in the bladder and behind the os penis.
What is the surgical approach?

30.1.2010
Domitor 0.3ml IV
Isoflurane gas
Antisedan 0.3 ml IM at the end of surgery

IV glucose 200 ml pre-surgery
Hartman Solution IV 2 days post op
Baytril 0.3 ml and Rimadyl 0.2 ml SC

31.1.2010. Ate l can A/D diet. T=38.7 deg C
To flush bladder again. Lots of bleeding and debri

SURGERY on 30.1.2010
Cystotomy only. Used catheter via bladder and via penile urethra to dislodge all stones via flushing many times. No need urethostomy in many cases although on first impression, a urethostomy behind the os penis would seem logical.
Catherised 3 days. Warded.

Roboroskvi's black lump - strangulated testicle?

This dwarf hamster bit me and Alice, a 4th-year vet student seeing practice at Toa Payoh Vets in Jan 2010. The Roboroskvi did not mind being handled but got fed up of being handled to be examined so many times. He bit my finger as I checked on him post-operation. Sharp incisor teeth. There was no blood at first. Suddenly the dam burst and I had to wash the blood off my finger. I asked Alice if she had been bitten. She said "Yes".

This high-speed Roboroskvi was 9 months old. His lady owner brought him in for a consultation as she saw this blackish lump in the lower groin area on the right side. A rather big black lump of 8mm x 4mm appeared on the right inguinal area. What was it? Was it a gangrenous testicle? How did it appear? What to do now?

There was no on the other side. Surgery to remove the lump was the only option.

Zoletil 50 given IM. Growth removed. Skin wound of 6 cm long was stitched with 5/0 absorbable sutures. Hamster was OK and I sent him home to a happy lady owner. I did not send the lump for histopathology as that meant the owner had to pay more. There was considerable bleeding on excision of the growth. Unlike dogs, it would be difficult to clamp below the growth in this hamster. Fine ophthalmic forceps could be used to clamp but there was little space. In any case, this hamster survived.
For hamsters with growths, there is no justification to give antibiotics and hope they will disappear. The vet has to use his or her good judgment as regards ethics and the economics of the practice. Vets must be careful as there may be negligence litigation/complaints if the hamster with an obvious growing tumour is treated with just drugs, powder and some homeopathic/herbal medication.









If the vet does not want to do hamster surgery, it is best to ask the owner to go elsewhere rather than just prescribing some drugs. In this case, a strangulated testicle or gangrenous lump may rot, become infected or ulcerated and kill the hamster after some weeks.

P.S. Examine speedy dwarf hamsters like the Roboroskvi above a big bowl so that the hamster will drop onto the bowl if they escape your grasp. On the examination table, they may sprint away before the vet assistant or nurse could react and fall off the table!

Dear Doctor Sing,

Happy New Year to you & I hope this email finds you well...

I would like to seek your advice on one of my dwarf hamster. She's currently 1.5yrs old and had been in good health all these while.. Just 2 days ago, i notice that she is excessively scratching her right ear & it became obvious that the outer ear area turns red and slightly sore...

Few months back my other male dwarf hamster (Name) had ear infection as the bathing sand and bedding went into his ear, he recovered after treated by you in Oct 2009. I've since then stopped all bathing sand and switched to towel as bedding for all my hamster. I rule out the possibility of mites or mange as their cage are kept clean and i change their towel twice a day.

I wonder if it helps if i were to purchase from your clinic the same medicines (pink & white colour to stop itchness and prevent inflammation if i remembered correctly) to treat this hamster.

I've enclosed pictures of my hamster and I hope the above information is useful.

Looking forward to hearing from you soon.

Thank you so much & wishing you a good weekend ahead :D


Best regards,

Name of Lady Owner


E-MAIL REPLY FROM DR SING was given to the owner. "It is best to examine the hamster as e-mail pictures are not clear. The owner brought the hamster in for consultation and accepted my advice to get the tumour/swelling on the side of the ear removed. It may become infected or grow larger."

Thanks for pictures of the previous hamster I treated. As I don't read email regularly, pl tel me if you need any answers. In any case, your hamster is OK (after electro-surgery). It has the same inflammation of the ear canal as the previous one. Liquid and black particles inside the ear canal were exposed during surgery to remove the lump outside the ear canal. I thought you had used some ear lotion or normal saline.

Hi Doctor Sing,

It's been 5 days since i brought my hamster back and have fed her with the required medication on a daily basis. She's eating & exercising normally and looking at her ear, the little wound has dried up but she's rather sensitive whenever i tried to clean or remove the layer of dried skin which is in dark red or black color.

Just to check if i can leave it alone, will the dried layer automatically drop off by itself or will there be a likelihood that she may accidentally push it further into her ear?

Thank you.

Regards,

Name of Lady Owner

I just returned from overseas. The blood clot is the wound left over when the tumour/swelling in the lateral canal of the ear was removed. It will dry up later and replaced by new skin. Remove it slowly. Remove bit by bit with the smallest cotton bud (dipped in warm water). It is hard to say whether the clot will cause a problem, but I don't think it will.

39. Pyometra in aged female dogs cause pain to the sister

Pet Shop Visit in December 2009
Three years had passed by. I seldom kept in contact with this pet shop girl till recently as I don't go to the shop to do puppy vaccinations. However, I visited to ask her to re-pack some Hill's Prescription d/d dog food for me as many owners want small packets.

Another aged female Cocker Spaniel of around 12 years old, belonging to her sister had open pyometra some months ago. The sister had put the dog on antibiotics for some time. "It is best to spay her," I advised. But the sister just would not want to. I don't know why.

Finally, the dog was operated by another vet and survived. "But I have to provide my dog (Golden Retriever) for blood donation as the platelet count was very low," the pet shop girl said when I visited her pet shop. That was good news. But there was a high cost involved.

Spaying the female dog early would have prevented pyometra in these two cases which were not handled by me or my Surgery. As an alternative, inspect your female dog monthly. Record her dates when she has her heat. Observe the colour and nature of the blood spots. If the blood looks brownish or yellowish and starchy, it is time to get her spayed. Unfortunately, in closed pyometra, there are no discharge. Just vomiting. Or loss of appetite and lethargy.

It seemed a repeat of history during this visit. There was the pyometra of her sister's dog. There was also a slim teenaged girl working as a part-timer busy cleaning up the kennels at 11 am when I visited. However, this short girl was not thin She was OK and could be considered "handsome". But she had a ring in between her nostrils. Her unique selling proposition.

She reminded me of the bulls I saw practice as a 4th year vet student some 30 years ago in Scotland in 1973. Such bulls have a ring between their nostrils if my long-term memory is still intact. Why would such a young teenaged girl with normal good looks put ring her nose I just cannot understand. She hung with her friends past midnight at the Junction 8 shopping mall in Bishan and was working part-time to earn some money.

"Do you want to employ her as a part-timer," the pet shop girl asked me. "She can try out for one day without payment first."

"I need a girl who knows how to write reports and use the Excel and Microsoft Word," I told the pet shop girl. It is difficult to find such part-timers. I can't employ any nose-ringed girl or boy as part-timers no matter how hard working they are. Buttons embedded in the girl's tongue. Well, I don't know how such girls do it. It must be very painful. However times have changed for some young adults.

As for pyometra in aged female dogs, things have not changed much in the treatment or cure. Prognosis is poor when the owner delays veterinary treatment and when there is vomiting. Spaying would not be of much help once the female dog has persistent vomiting for several weeks as the kidneys had been damaged. Some 10 years ago, I had an uneducated owner bad-mouthing me for not curing the dog after the spay of her persistently vomiting dog. The dog survived the spay but continued vomiting due to kidney disease, not to professional incompetence of spaying! The lady owner did not want any blood test but the cheapest veterinary cost. Sometimes it is best not to handle such personalities who want "cheap and good" veterinary services if the vet cares about the reputation built up over the years. They tend to bad-mouth the vet in the Singapore internet forum nowadays and this webpage will persist forever for people all over the world to see.



For aged female dogs with pyometra, family members may get is the pain or in this case, the younger sister felt the pain of the suffering of the aged female dog.

For those who believe in prevention of pyometra, spay your female dog early, 3 months after the first heat.
