Q

Which surgical approach is recommended for a cervical oesophageal injury?

A

A ventral middle approach is recommended for most surgery on the cervical oesophagus because the anatomy of this region is more familiar to us, it allows us to recognise and avoid important structures such as the vagosympathetic trunks, carotid arteries, jugular veins and trachea, and it allows access to both right and left sides of the oesophagus simultaneously.

Q

Of the following imaging modalities which gives the most information about the site and severity of a stick injury?

Q

What is the general recommendation for suturing an oesophagotomy incision?

A

Perform a one-layer closure using a simple interrupted approximating pattern.

20
Q

The blood supply to the stomach originates from which artery?

A

Celiac

21
Q

Identify the area of small intestines (duodenum, jejunum, or ileum) from the description:
“This part of the small intestines is suspended by a relatively short mesentery compared to the other sections of small intestine.”

A

Duodenum

22
Q

When a dog is positioned in right lateral recumbency, if there are moderate amounts of fluid and air in the stomach, which part of the stomach will become filled with fluid? (2)

A

Pyloric antrum and pylorus

23
Q

Which is the strength holding layer of the intestines?

A

Submucosa

24
Q

Identify the area of small intestines (duodenum, jejunum, or ileum) from the description:
“A segment of this part of the intestine is anchored deep (dorsal) within the abdomen to the descending colon by a ligament.”

A

Duodenum

25
Q

The commonest intestinal tumour diagnosed in the dog is:

A

Adenocarcinoma

26
Q

The term epithelial “restitution” refers to the:

A

Mobilisation of epithelial cells around a defect in the gastric mucosa and migration of these cells to cover the defect.

27
Q

What techniques are suitable for managing necrosis of the fundus secondary to GDV? (3)

A

Invagination of the necrotic portion of the stomach.

Partial gastrectomy using an automatic stapling device.

Partial gastrectomy with a sutured closure.

28
Q

The fundus, body and pyloric antrum of the stomach all produce mucus. Which of the following substances does the pyloric antrum also produce?

A

Gastrin

29
Q

Which breed of dog is recognised as being at increased risk of congenital hiatal hernia?

A

Shar pei

30
Q

The dehiscence rate associated with enterotomy to remove intestinal foreign bodies in dogs has recently been reported in a large retrospective study as:

A

2%

31
Q

The loss of domain that can occur with chronic abdominal/diaphragmatic hernias and ruptures is explained by which of the following statements?
A) The inability to close the abdominal wall following chronic “emptiness” of the abdomen causing “contraction” of the body wall.

B) The compromise to the circulation that occurs due to the increase in intra-abdominal pressure that can occur when herniated abdominal organs are returned to a chronically “empty” abdomen and the abdominal incision is closed under tension.

C) The inability to reduce the herniated organs due to adhesion formation.

D) The compression of blood supply to the herniated organs by twisting of the vascular pedicle of compression by the hernial ring.

A

A) The inability to close the abdominal wall following chronic “emptiness” of the abdomen causing “contraction” of the body wall.

32
Q

Which of the following suture materials would be the best choice for repair of a hernia?

Cat gut.

Poliglecaprone.

Polydioxanone.

Silk.

A

polydioxane
This suture material is monofilament and slowly absorbed with a long duration of maintaining tensile strength. These characteristics make it a good choice of suture material for repair of a rupture or hernia.

33
Q

Which of the following factors can cause postoperative ileus?

A) General anaesthesia.

B) Opioid analgesia.

C) All the options.

D) Hypokalaemia.

A

C) All the options.

34
Q

Which of the following findings on abdominal ultrasound examination will not be present in a patient that is suffering post-operative ileus?

A) An absence of peristalsis.

B) Free abdominal fluid.

C) Fluid filled loops of intestine

D) All the options.

A

B) Free abdominal fluid.

35
Q

Sliding hiatal hernia may be difficult to identify because…

A

The herniation of abdominal contents is intermittent.

36
Q

Re-expansion pulmonary oedema associated with repair of a chronic diaphragmatic rupture occurs most commonly at what time in relation to surgery?

A

Within 2 days of surgery

37
Q

A diagnosis of perineal hernia is usually made by…

A

Rectal exam

38
Q

Which breed of dog is recognised as being at increased risk of congenital hiatal hernia?
