7) c Neoplasm

The most common clinical presentation of Meckel’s diverticulum is gastrointestinal bleeding, which occurs in 25% to 50% of patients who present with complications

intestinal obstruction occur as a result of a volvulus of the small bowel around a diverticulum associated with a fibrotic band attached to the abdominal wall, intussusception, or, rarely, incarceration of the diverticulum in an inguinal hernia (Littre hernia)

Diverticulitis accounts for 10% to 20% of symptomatic presentations.

Neoplasms can also occur in a Meckel’s diverticulum, with NET as the most common malignant neoplasm (77%). Other histologic types include adenocarcinoma (11%), which generally originates from the gastric mucosa, and GIST (10%) and lymphoma (1%).

The Hinchey classification is commonly used to describe
the severity of diverticular disease complicated by perforation
and is an additional tool that may be used to guide overall management:

Stage I: Small, confined pericolonic or mesenteric abscess

Stage II: Larger, walled-off pelvic abscess

Stage III: Generalized purulent peritonitis

Stage IV: Generalized fecal peritonitis

Hinchey stages I and II can often be managed with administration of antibiotics and percutaneous drainage, if technically feasible

9) a

According to  Park's classification

Intersphincteric fistulae (45%) do not cross the external sphincter. Most commonly they run directly from the internal to the external openings across the distal internal sphincter

Trans-sphincteric fistulae (40%) have a primary track that crosses both internal and external sphincters (the latter at a variable level) and which then passes through the ischiorectal fossa to reach the skin of the buttock.

Supra sphincteric and Extra sphincteric are rare

Bailey page 1364

10) d

Carcinoid appendix are the most common tumors of the appendix and seen in upto 0.3-0.9% of appendectomy specimen.

They are well circumscribed lesions seen near the distal part of appendix. 

Size of the lesion corresponds with metastatic potential as well as malignant behavior.

Carcinoids smaller than 1 cm are typically thought to behave in a benign manner and are cured with
appendectomy. Carcinoids larger than 2 cm are treated more
aggressively, however.
