Q1.”The seal of signet ring” appearance is seen in
a.adenocarcinoma
b.primary mucoid carcinoma
c.carcinoid tumour
d.endometrioma
ANS1.b Primary mucoid carcinoma
Q2.All feature of signet ring carcinoma of rectum except
a.grow rapidly
b.early metastase
c.poor prognosis
d.central nucleus
ANS2-d.
In primary mucoid carcinoma ,the mucus lies within the cells
,displacing the nucleus to the periphery ,like the seal of a signet ring .
Q1 The most common abnormality found in colorectal cancer is
a.mutation in the Wnt signalling pathway
b.mutation in TP53 GENE
c.mutation in TGF -beta gene
d.deleted DCC gene
ANS1.a
The most commonly mutated gene is the APC gene
Q2.Cellular or physiological effects resulting from external or
environmental factors that switch genes of or on is known as
a.epigenetic alternations
b.hypogenetic alternation
c.hypergenetic alternation
d.random alternation
ANS .a
Q1.Steps of Delorme operation are all except
a.circumferential stripping of rectal mucosa over the length
of the prolapse
b.removal of redundant underlying muscles
c.excision of excess mucosa
d.mucosal anastomosis
ANS1.b
The underlying muscle is plicated with a series of sutures
,so that the rectal muscle is concertinaed towards the anal canal .The
resulting effect is to reduce the prolapse as plicated ring of muscle above the
anal canal
Delorme operation may be preferred in patients with short segment full rectal prolapse
Q2.The procedure of choice in patients presenting with
incarcerated and strangulated rectal prolapse is
a.Delorme operation
b.Thiersch operation
c.Altemeier s procedure
d.LVMR
Q2.c
Altemeier procedure is a good alternative perineal procedure
to the Delorme operation ,particularly following recurrence .
