Exploratory Laparotomy

What is an Exploratory Laparotomy?

The exploratory laparotomy, often referred to as the Ex Lap, is a diagnostic tool. The surgery is performed when the diagnostic tests readily available to a practitioner do not provide an explanation for the patient’s abdominal clinical signs. The ex lap can help you get answers and solve a problem.

Situational Awareness

The Ex Lap can be both lifesaving and money sparing when used appropriately and timely. The difficulty associated with this surgery is the level of associated uncertainty. Some questions you may be asking yourself are:
  1. Will I find the foreign body (FB)? What if I don’t?  
  2. What if I find a tumour?  What if I don’t? 
  3. Will the problem be beyond my skill level?
The key is for you and your client to be prepared, clearly there is no possible way to be prepared to surgically manage every possible scenario, but you can prepare for how you will handle different types of situations. You will either come out of the ex lap with the FB, with the diagnostic biopsies, maybe with pictures, samples and recommendation for referral or maybe a recommendation for euthanasia, but you will have an answer and a plan. You, your patient and your client will no longer be stuck in the ‘not knowing’.

What the client needs to know:

Step by Step Ex lap

Liver Biopsy: Create a loop with the suture material (3-0 monofilament will work well). Ensnare the tip of a liver lobe with the suture loop.
Liver Biopsy: Pull the suture loop tight around the liver lobe tip, thereby strangulating the parenchyma and vessels. Cut the liver tissue leaving the suture material in situ. Place the liver sample in formalin.
Intestinal biopsy: With a #15 blade make a small incision (about 1cm long) along the mesenteric border of the loop of bowel.
Intestinal biopsy: Using Metzenbaum scissors excise a FULL thickness strip of tissue, about 1mm wide, along one edge of the incision. Place the sample in the formalin jar.
Intestinal biopsy: Close the biopsy site with a simple interrupted, full thickness, apposing (not crushing) pattern. I like to start the closure in the centre of the enterotomy and I use a 3-0 or 4-0 shorter acting monofilament suture material.
Intestinal biopsy: When the closure is complete, do a leak test before moving on.

Q & A

How long does an exploratory laparotomy take?

The exploratory of the abdominal organs, once the approach is complete, only takes between 5 and 10 minutes, depending on how many anomalies there might be to observe and consider. However, taking the biopsies of the various organs can be time consuming. The abdominal incision is also of a significant length so closure can also take some time. An ex lap can easily take 60-70 minutes skin-to-skin (assuming no major anomalies found and all usual organs biopsied).

How long does it take a dog to recover from an ex lap?

The recovery from this surgery is very much dependent on what has been found at surgery and how ill the patient was going into surgery. However, the recovery tends to be speedy with a routine ex lap and biopsies in a stable patient. The abdominal incision will take approximately 2 weeks to heal.
