What is the most appropriate method for performing a gastric bypass using
laparoscopic techniques? ---------CORRECT ANSWER-----------------A circular stapler
for anastomosis
Explanation: A circular stapler is most commonly used in laparoscopic gastric
bypass surgery to form an anastomosis between the stomach and small bowel.
During laparoscopic gastric bypass surgery, which of the following is a primary
concern when dividing the mesentery? ---------CORRECT ANSWER-----------------
Injury to the superior mesenteric artery
Explanation: The superior mesenteric artery runs close to the mesentery and
can be injured during dissection, leading to significant complications such as
bowel ischemia.
In laparoscopic bariatric surgery, the most common site for gastric perforation
during sleeve gastrectomy is: ---------CORRECT ANSWER-----------------The greater
curvature of the stomach
Explanation: Gastric perforation during sleeve gastrectomy most commonly
occurs along the greater curvature due to the pressure exerted during stapling.
,When performing a laparoscopic Roux-en-Y gastric bypass, the mesenteric defect
must be closed to: ---------CORRECT ANSWER-----------------Prevent internal
herniation
Explanation: Closing the mesenteric defect helps prevent internal herniation, a
potential complication where bowel loops can protrude through the defect into
abnormal locations.
Which of the following intraoperative complications is most likely to occur with
increased intra-abdominal pressure during laparoscopic surgery? ---------CORRECT
ANSWER-----------------Hypoventilation due to diaphragm compression
Explanation: Increased intra-abdominal pressure can compress the diaphragm,
limiting lung expansion and leading to hypoventilation, which may cause
respiratory difficulties.
Which laparoscopic procedure is most likely to require the use of a vascular
stapler? ---------CORRECT ANSWER-----------------Laparoscopic sigmoid colectomy
Explanation: In laparoscopic sigmoid colectomy, a vascular stapler is used to
transect the colon and ligate blood vessels, as it is an essential tool for resection
and anastomosis.
,During laparoscopic surgery, which of the following is most critical when using
bipolar electrocautery to coagulate a vessel? ---------CORRECT ANSWER---------------
--Ensuring adequate insulation of the instruments
Explanation: Proper insulation of the instruments is essential for safety when
using bipolar electrocautery, as it helps to prevent unintentional burns or tissue
damage to surrounding structures.
Which complication is most commonly associated with incorrect placement of the
trocar during laparoscopic surgery? ---------CORRECT ANSWER-----------------Bowel
perforation
Explanation: Incorrect placement of the trocar, especially in areas with dense or
distorted anatomy, can result in bowel perforation, which is a significant risk in
laparoscopic surgery.
WRONG ANSWERS = Vascular injury, Increased intra-abdominal pressure,
Excessive bleeding from the abdominal wall
In laparoscopic hernia repair, the mesh is typically placed: ---------CORRECT
ANSWER-----------------Directly over the hernia defect
Explanation: In laparoscopic hernia repair, the mesh is typically placed directly
over the defect in the abdominal wall to reinforce the area and prevent
recurrence.
, The critical view of safety technique in laparoscopic cholecystectomy is primarily
aimed at: ---------CORRECT ANSWER-----------------Minimizing the risk of bile duct
injury
Explanation: The critical view of safety involves identifying the cystic duct and
artery, ensuring they are separate and fully dissected to minimize the risk of
injury to the common bile duct.
Which instrument is primarily used for cutting and coagulating tissue
simultaneously? ---------CORRECT ANSWER-----------------Harmonic scalpel
Explanation: The harmonic scalpel uses ultrasonic energy to cut and coagulate
tissue simultaneously, providing a precise method of tissue dissection with
minimal thermal spread.
When performing a laparoscopic appendectomy, what is the most significant risk
when visualizing the appendix in obese patients? ---------CORRECT ANSWER---------
--------Difficulty identifying the appendix due to excessive adipose tissue
Explanation: In obese patients, the presence of excess abdominal fat can
obscure the view, making it difficult to properly identify and dissect the
appendix.
