Welcome to the procedure part of the Meckel's diverticulum / bowel resection module. Here the learner will go through a pre-test and interactive case scenario to learn about laparoscopic management of Meckel's diverticulum.

Pre-test[edit | edit source]

Learners will first take a pre-test to assess their baseline knowledge of the topic. This test is available on our interactive platform and gives real-time grading for learners to immediately assess their knowledge coming into the module. It is also copied in appropedia format below. On our platform, answer explanations are not displayed for the pre-test (but are displayed in the post-test).

1 What percent of lesions resulting in gastrointestinal bleeding can be identified by performing both upper and lower endoscopy?


2 What is true about Meckel’s diverticulum?

Meckel’s diverticulum involves only the submucosal layer of the small intestine
Intestinal obstruction or hemorrhage occur in over 80% patients with Meckel’s diverticulum
Meckel’s diverticulum occurs due to the failure of the omphalomesenteric (vitelline) duct to obliterate
Meckel’s diverticulum is a rare congenital anomaly of the GI tract

3 Which of the following is the most common type of mucosa found in a Meckel's diverticulum?


4 Of the imaging tests listed, which is associated with the highest accuracy in the diagnosis of Meckel’s diverticulum?

CT scan

5 Why does ulceration occur with Meckel’s diverticulum?

The diverticulum may contain acid secretion from ectopic gastric tissue
Localized inflammation results from enteroliths in the diverticulum
Physical constriction of the bowel leads to ischemia and ulceration
Mucosa-associated lymphoid tissue causes local inflammation

6 Which of these are suggestive of an air embolism?

Drop in central venous pressure
"Mill wheel" murmur

7 The port configuration for a diagnostic laparoscopy to examine for small bowel pathology should allow for:

The triangulation of the stomach in the left upper quadrant
The triangulation of the distal small bowel in the right lower quadrant
The triangulation of the liver in the right upper quadrant
The triangulation of the rectum in the pelvis

8 Which anastomosis has the highest risk of anastomosis leak or stricture?

Transverse colonic

9 Which of these can contribute to increased risk of anastomotic leak?

Radiation of intestine
Pre-operative bowel prep
Intraoperative hypertension
Early advancement of diet

10 Which nerve could potentially be irritated during laparoscopic small bowel resection, leading to shoulder pain?

Pelvic splanchnic

The answers, with explanations, are available for review in the post-test which is accessible here for download as a pdf.

Case scenario[edit | edit source]

The psychomotor learning is embedded in the sequence of a full clinical case, allowing the learner to digest pre-, intra-, and operative concepts of ectopic pregnancy.

Learners will go through an interactive case scenario with embedded course material. The case scenario is presented in a question / answer format. As learners progress through the case, they will digest information that is presented to them as they answer case questions. It is highly recommended that the learner be familiar with this content before proceeding to the skill pages.
