All patients with complete small bowel obstruction require blood and plasma for resuscitation. E. If small bowel resection must be performed, a stoma and mucous fistula is necessary as anastomosis.

Answer 82

A. Immediate operation is warranted as soon as the diagnosis is made. Clarification: Complete small bowel obstruction requires immediate surgical intervention because the risk of complications, such as bowel strangulation, ischemia, and perforation, is high. B. Nasogastric decompression may be attempted in partial obstructions but is not appropriate for complete obstruction. C. Strangulation signs (e.g., fever, tachycardia, localized pain, leukocytosis) further emphasize the need for prompt surgery, but in complete obstruction, immediate surgery is already indicated. D. Blood and plasma resuscitation is not universally required unless the patient is hemodynamically unstable. E. A stoma and mucous fistula are not routinely required and are reserved for cases with extensive resection or gross contamination.

Question 83

68. With regards to Meckel’s diverticulum, which of the following statements is/are true? A. They are found in various anatomic forms and clinical presentations in 50% of the population. B. They are true diverticula. C. Most complications occur in the elderly. D. Diverticulitis is the most common complication. E. None of the above.

Answer 83

B. They are true diverticula. Clarification: Meckel's diverticulum is a true diverticulum because it contains all layers of the intestinal wall. Complications are more common in children, not the elderly. The most common complication is bleeding, not diverticulitis.

Question 84

69. Meckel’s diverticulum originates from the: A. Foregut B. Midgut C. Hindgut D. Stomach E. Colon

Answer 84

B. Midgut Clarification: Meckel’s diverticulum arises from a persistent omphalomesenteric duct, which originates from the midgut during fetal development.

Question 85

70. Volume replacement in a patient with small bowel obstruction is probably adequate when: A. Urine output is established. B. The blood urea nitrogen and creatinine values are within the normal range. C. The urinary sodium concentration exceeds 40 mEq/L. D. Urinary output exceeds 0.5 mL/kg body weight/hour. E. The serum electrolytes are normal.

Answer 85

D. Urinary output exceeds 0.5 mL/kg body weight/hour. Clarification: Urinary output is the most reliable indicator of adequate fluid resuscitation and reflects proper renal perfusion and intravascular volume status.

Question 86

71. Amyand’s hernia involves the: A. Meckel's Diverticulum B. Appendix C. Small Intestine D. Ovary

Answer 86

B. Appendix Clarification: Amyand's hernia is a rare type of inguinal hernia where the vermiform appendix is located within the hernial sac.

Question 87

72. The McVay repair involves suturing the: A. Cooper’s ligament & Conjoint tendon B. Inguinal ligament & Internal oblique C. Transversalis fascia & Cooper’s ligament D. External oblique aponeurosis & Iliopubic tract

Answer 87

A. Cooper’s ligament & Conjoint tendon Clarification: In the McVay repair, the conjoined tendon (transversus abdominis and internal oblique) is sutured to Cooper’s ligament to repair inguinal and femoral hernias.

Question 88

73. The external oblique aponeurosis gives rise to the: A. External spermatic fascia B. Cremasteric muscle C. Internal spermatic fascia D. Dartos muscle

Answer 88

A. External spermatic fascia Clarification: The external oblique aponeurosis forms the external spermatic fascia, which surrounds the spermatic cord and testis.

Question 89

76. Above the arcuate line, the posterior rectus sheath is formed by: A. Internal oblique aponeurosis, transverse abdominis aponeurosis B. External oblique aponeurosis, transversalis fascia C. Transversalis fascia only D. Internal oblique aponeurosis, external oblique aponeurosis

Answer 89

A. Internal oblique aponeurosis, transverse abdominis aponeurosis Clarification: Above the arcuate line, the posterior rectus sheath is formed by the aponeuroses of the internal oblique and transverse abdominis muscles.

Question 90

77. The triangle of pain is defined by the following structures: A. Iliopubic tract, gonadal vessels, femoral nerves B. Inguinal ligament, rectus sheath, epigastric vessels C. Iliopubic tract, Cooper's ligament, ilioinguinal nerve D. Gonadal vessels, transversalis fascia, femoral artery

Answer 90

A. Iliopubic tract, gonadal vessels, femoral nerves Clarification: The triangle of pain is a region bounded by the iliopubic tract superiorly, gonadal vessels, and contains important femoral nerves. It is a critical area during hernia repair to avoid nerve injury.

Question 91

78. According to the Nyhus Classification System, Type IIIA refers to: A. Indirect hernia B. Direct hernia C. Femoral hernia D. Recurrent hernia

Answer 91

B. Direct hernia Clarification: In the Nyhus Classification System, Type IIIA refers to a direct inguinal hernia associated with a weakened transversalis fascia.

Question 92

79. The surgical treatment for Nyhus Type I hernia is: A. Bassini B. Marcy Repair C. Lichtenstein Repair D. Shouldice Repair

Answer 92

A. Bassini Clarification: For Nyhus Type I hernia (small, indirect hernia with a normal internal ring), the Bassini repair is a common surgical option. In children or young adults, a Marcy repair (high ligation of the hernia sac) may also be performed.

Question 93

80. When part of the wall of the hernia sac is formed by the herniating viscus, this is called: A. Sliding inguinal hernia B. Richter’s hernia C. Amyand’s hernia D. Littre’s hernia

Answer 93

A. Sliding inguinal hernia Clarification: In a sliding inguinal hernia, part of the hernia sac is formed by a viscus (e.g., colon or bladder wall). This condition is more common in older adults.

Question 94
