ABDOMINAL WALL and ACUTE ABDOMEN Multiple Choice Questions and Answers pdf :-

1. The most common hernia in females is:
A. Femoral hernia.
B. Direct inguinal hernia.
C. Indirect inguinal hernia.
D. Obturator hernia.
E. Umbilical hernia.
Answer: C

DISCUSSION: Indirect inguinal hernias are the most common hernia in both females and males. Femoral hernias are more common in females than in males.

2. Which of the following statements regarding unusual hernias is incorrect?
A. An obturator hernia may produce nerve compression diagnosed by a positive Howship-Romberg sign.
B. Grynfeltt’s hernia appears through the superior lumbar triangle, whereas Petit’s hernia occurs through the inferior lumbar triangle.
C. Sciatic hernias usually present with a painful groin mass below the inguinal ligament.
D. Littre’s hernia is defined by a Meckel’s diverticulum presenting as the sole component of the hernia sac.
E. Richter’s hernia involves the antimesenteric surface of the intestine within the hernia sac and may present with partial intestinal obstruction.
Answer: C

DISCUSSION: Sciatic hernias usually present with intestinal obstruction or a mass in the gluteal or infragluteal region.

3. Staples may safely be placed during laparoscopic hernia repair in each of the following structures except:
A. Cooper’s ligament.
B. Tissues superior to the lateral iliopubic tract.
C. The transversus abdominis aponeurotic arch.
D. Tissues inferior to the lateral iliopubic tract.
E. The iliopubic tract at its insertion onto Cooper’s ligament.
Answer: D

DISCUSSION: Placement of staples inferior to (below) the lateral iliopubic tract may result in injury to the lateral femoral cutaneous nerve or the genitofemoral nerve. Staples should also not be placed within the triangle of doom, owing to the risk of major vascular injury.

4. The following Nyhus classification of hernias is correct except for:
A. Recurrent direct inguinal hernia—Type IVa.
B. Indirect inguinal hernia with a normal internal inguinal ring—Type I.
C. Femoral hernia—Type IIIc.

Answer: E

DISCUSSION: An indirect inguinal hernia with destruction of the transversalis fascia of Hesselbach’s triangle is classified as a Type IIIb hernia. Also classified as Type IIIb hernias are sliding, pantaloon, and massive scrotal hernias. Type II hernia is an indirect inguinal hernia with a dilated internal ring but without displacement of the inferior deep epigastric vessels or destruction of the transversalis fascia of Hesselbach’s triangle.
