HCC Cancer

Q) Which of the following is true about screening in hepatocellular carcinoma (HCC Cancer) 

a) Alpha feto protein should be done 6 monthly

b) Ultrasound abdomen should be done 6 monthly

c) Candidates for liver transplant should be screened every 3 months

d) Nodules more than 2 cm should be followed up  more regularly

Answer b

Cirrhosis is prone for development of HCC. Screening has to be stringent.  Earlier ultrasound of liver and alpha feto protein were both used for screening

In 2009 Marrero et al demonstrated the suboptimal accuracy of AFP and after that it has been removed from the screening protocol and now only ultrasound is being done.

The screening recommendation is not for those patients with severe associated conditions and with advanced liver disease who are already considered for  transplant. So there is no screening for those who are already listed. Nodules more than 1 cm are highly suspicious where as in nodules less than 1 cm only 40% will be malignant.

Mass in Right lower quadrant

Q) A 55 year old lady presents with vague pain in right lower abdomen. Physical examination reveals a well defined mass there which is non tender and freely mobile. It is non pulsatile as well. What is the most likely possibility?

a) Appendicular mass

b) Mesenteric cyst

c) Perforated tubo ovarian mass

d) Meckel's diverticulum

Answer

b

Mesenteric cysts are uncommon lesions found in this age group. It typically presents as a freely mobile mass  which moves perpendicular to small blwel axis. It is painless as well.

Appendicular mass will have a preceding history of pain abdomen

Similarly perforated  tubo ovarian mass will also have a history of pain 

Meckel's diverticulum does not present as this kind of mass

Recurrent Pyogenic Cholangitis

Q) Not true about  recurrent pyogenic cholangitis :

a) Mostly there are intrahepatic strictures with involvement of the left side duct

b) It can present as choledocho duodenal fistula

c) There is complete biliary obstruction which  leads to marked jaundice and pruritis

d) MRCP and other other cholangiography can be diagnostic

Answer c

In recurrent pyogenic cholangitis (RPC)  complete obstruction does not occur and jaundice and pruritis is not marked.  RPC is a disease commonly seen in young Asians (also known as oriental cholangiohepatitis) which leads to multiple strictures in extra or intrahepatic ducts.

Association with Ascaris lumbricoides and Clonorchis sinensis has been noted.

It can present as choledocholithiasis  with stricture, choledochoduodenal fistula, acute pancreatitis, secondary biliary cirrhosis and can lead to cholangiocarcinoma.

MRCP can be diagnostic and is preferred because of its non invasive nature.

Flaps in Plastic Surgery

Q. Z plasty is an example of 

a) Advancement flap

b) Delayed flap

c) Transposition flap

d) Rotation flap


Answer for all 

Flaps in plastic surgery are the cornerstone of management of skin and wound defects.

Advancement flaps are used to cover skin defects in face, scalp and neck. Examples of advancement flaps are monopedicled flaps,

bipedicled and V Y advancement flap.

Delay of flap is a surgical preconditioning, in which the blood supply  is partially blocked prior to actual procedure. It increases the length of the flap as well as its uptake rate.

Transposition flap - used in head and neck surgery, a rectangular flap is rotated.
