According to Goodsall's rule, a fistula-in-ano with an external opening anterior to the transverse anal line usually:
सही उत्तर: ग) Runs a straight radial course to the dentate line
Anterior external openings usually lead straight, along a radial path, to the internal opening. Posterior openings follow a curved tract to the posterior midline. The rule is less reliable for openings more than about 3 cm from the anal verge.

The most common site of a chronic anal fissure is:
सही उत्तर: ख) Posterior midline
Most fissures are in the posterior midline, where blood supply is poorest. Fissures in a lateral position should raise suspicion of Crohn's disease, TB, HIV or malignancy. Lateral internal sphincterotomy is the surgical treatment of choice for chronic fissures.

The Trendelenburg test in varicose veins is used to assess competence of the:
सही उत्तर: क) Saphenofemoral junction
After the veins are emptied and the saphenofemoral junction is compressed, rapid filling when the pressure is released shows saphenofemoral incompetence. Perthes' test is used to assess patency of the deep veins.

The most common site of an abdominal aortic aneurysm is:
सही उत्तर: घ) Infrarenal aorta
About 90% of abdominal aortic aneurysms are infrarenal, which is the region most prone to atherosclerotic degeneration. Elective repair is usually advised at a diameter of 5.5 cm or more, or when the aneurysm grows quickly or causes symptoms.

An ankle–brachial pressure index (ABPI) below which value is generally taken as diagnostic of peripheral arterial disease?
सही उत्तर: ग) 0.9
An ABPI below 0.9 indicates peripheral arterial disease. Very low values (around 0.5 or less) suggest critical ischaemia. Values above 1.3 suggest non-compressible, calcified vessels, as in diabetes.

Thromboangiitis obliterans (Buerger's disease) is most strongly associated with:
सही उत्तर: ख) Tobacco smoking

Virchow's triad for venous thrombosis comprises:
सही उत्तर: क) Stasis of blood, endothelial injury and hypercoagulability
Virchow's triad describes the factors that cause thrombosis. Surgical patients are at risk from immobility (stasis), operative trauma (endothelial injury) and the post-operative hypercoagulable state.

-
Which feature best distinguishes a keloid from a hypertrophic scar?
सही उत्तर: घ) A keloid extends beyond the margins of the original wound
Keloids grow beyond the original wound edges, rarely regress and often recur after excision. Hypertrophic scars stay within the wound margins and often improve over time.

The most important prognostic factor in localised cutaneous malignant melanoma is:
सही उत्तर: ग) Breslow thickness
Breslow thickness, the depth of invasion in mm, is the strongest predictor of outcome and guides excision margins and T staging. Clark's level is an older anatomical system with less prognostic value.

Squamous cell carcinoma arising in a long-standing burn scar or chronic ulcer is called:
सही उत्तर: ख) Marjolin's ulcer
A Marjolin's ulcer is an SCC arising in chronic scars or ulcers. It is slow-growing, painless and, at least at first, does not spread to lymph nodes because scar tissue has few lymphatics. A rodent ulcer is basal cell carcinoma.
