Contraindication of Left lobe liver transplant

Contraindication of Left lobe liver transplant

Q) Absolute contraindication for left lobe LDLT is
A. Trifurcation of the portal vein
B. Bifurcation of portal vein in the right lobe of the liver
C. Aberrant right hepatic artery
D. Right Posterior duct draining into left hepatic duct


Trifurcation of portal vein is not a contraindication of  left lobe liver transplant  as we will get a single portal vein on the left side

9k= Contraindication of Left lobe liver transplant
Portal vein

Bifurcation of portal vein in right lobe does not matter because we are leaving the right lobe behind

Again right aberrant artery does not matter because that segment is left behind

Right post duct draining into left duct gives rise to two ducts on the left or a single duct which is quite high.

C3-4-FF3 Contraindication of Left lobe liver transplant
Right posterior duct to left






Retained antrum syndrome

Retained antrum syndrome

Q) True about retained antrum syndrome after gastrectomy  are all except

a) It is a persistent hypergastrinemic state

b) It is only seen after Billroth II Gastrectomy

c) Technetium labelled food is not helpful in diagnosing this condition

d) Serum gastrin is usually less than 1000 pg/ml

Answer c

 After billroth II gastrectomy, if a cuff of gastric mucosa remains with duodenum, this entity is called as retained antrum syndrome. This cuff of gastric mucosa is cut off from the proximal stomach and inhibitory effect of hormones such as VIP (Vasoactive Intestinal Peptide)  leading to a persistent hypergastrinemic state. ALso this gastric mucosa is continuously bathed by the alkaline contents of duodenum , which further increases the acid formation.

Both Basal and maximal gastric acid outputs increase but it is not as high as seen in zollinger ellison syndrome. Typically less than 1000 pg/ml

This condition can present as recurrent and persistent ulcerations. Technetium scanning is the diagnostic modality of choice. Treatment is re do surgery and antral excision.

Technetium pertechnate imaging has a sensitivity of 73% and specificity of 100%

Answer is B

Natural  orifice  transluminal  endoscopic  surgery (NOTES),  which  uses  natural  orifices  (transgastric, colonic,  urethral,  vagina)  to  introduce  an  endoscope,  has been  reported  since  early  2000  as  a  less  invasive  approach to  laparoscopy.  The  first  human  NOTES  transvaginal  cholecystectomy  was  reported  in  2007,  and  later  the  report  of a  hybrid  combination  of  flexible  scope  by  a  transvaginal approach  in  combination  with  an  umbilical  needle  or port  for  laparoscopic  instruments  for  retraction,  dissection,  or  clips  application.  This  hybrid  technique  allowed for  a  quicker  and  safer  procedure;  the  present  deficiency is  in  the  proper  endoscopic  instrumentation. For  the  trans vaginal  approach,  a  Foley  catheter is  placed,  a  dissection  is  performed  in  the  posterior vaginal  cul-de-sac  to  allow  a  port  placement,  and  when the  case  is  over,  the  closure  is  easier  than  a  transgastric or  transcolonic  approach,  which  continues  to  be  an  issue.

Esophagus Length DNB 2018

Esophagus Length DNB 2018

Q) Length of Esophagus

 A. 20cm
B. 25cm
C. 30-35cm
D. 40cm


29) b

The esophageal length is anatomically defined as the distance between the cricoid cartilage and the gastric
orifice. It ranges in adults from 22 to 28 cm (24
± 5 SD), 3 to 6 cm of which are located in the abdomen.

The shortest distance between the cricoid cartilage and the celiac axis is the orthotopic route in the posterior mediastinum, being 30 cm. The retrosternal (32 cm) and the subcutaneous route (34 cm) proved to be

B. Motor response
C. Verbal response
D. All

23) B, Motor response

Motor score is the best predictor of neurological outcome.

The m component of the GCS,  is not only linearly related to survival, but preserves almost all the predictive power of the GCS 


Spinal cord injury

Spinal cord injury

Q) Out of the following which will require Spinal immobilization most?
a. 22 yr Female had a high-speed motor vehicle collision who complains of backpain and no
b.16 yr male jumped from 6ft landed on both foot denies back pain and weakness
C. Gunshot injury
D. Abdominal injury

Answer is free 


Spinal cord injuries are a common cause of morbidity and expenditure. Mortality is associated with cervical injuries but not lower spinal cord injuries.

Motor vehicle accidents are the most common cause and gunshot injuries the least common for spinal cord injuries.

Mechanism of injury 

  1. Blunt trauma - Direct impingement, Ischemia, compression or bleeding 
  2. Penetrating - Laceration of spinal cord

Chance fracture - is a type of spinal cord fracture in which there is transverse fracture of all vertebral elements

Tropical Pancreatitis

Tropical Pancreatitis

Q) All are true about tropical pancreatitis except?

a. Associated with Tapioca.
b. Patients have  large stones with fibrosis.
c. It is Pre Cancerous

d) Onset of disease at 50 years 

  Free. See here for answers to other  questions and this question

Answer -d )Onset is at young age

Tropical pancreatitis

is an  idiopathic disease which begins in teens.  It has a high association with diabetes and Pancreatic duct calculi. It is common in South India, Asia, Africa and central America.





Hydrocarbons exposure

It is associated with SPINK 1 mutation

It is pre cancerous

IPSG data shows the cumulative risk of Pancreatic Cancer  in patients with Chronic Pancreatitis  (predominantly of alcoholic aetiology) was reported as 1.8 % and 4 % at 10 and 20 years respectively. This risk was reported to be independent of age, sex and type of pancreatitis.

The link between CP and PC is clearer in certain subtypes of CP like tropical pancreatitis and hereditary pancreatitis.

 Augustine et al. reported a 8.3 % incidence of pancreatic cancer in patients with tropical pancreatitis, which is much higher than western figures.


Pancreatic Cancer in Chronic Pancreatitis

Clinical Picture of tropical pancreatitis

Spontaneous fistula closure

Spontaneous fistula closure

Q) Adverse factor for spontaneous fistula closure:

a) Tract <1cm

b)Transferrin > 200

c) Location in esophagus

d) First surgery done in the same institution

Answer free

a) Tract less than 1 cm

Spontaneous fistula closure

Short-turnover  protein (prealbumin,  retinol-binding  protein,  transferrin)  levels should  be  measured  at  least  weekly  to  assess  the  adequacy of  protein  delivery. An  ongoing  catabolic  state  will adversely  affect  short-turnover  protein  levels,  even  with maximal  protein  delivery.

Failure  of  an  enterocutaneous  fistula  to  close  spontaneously  is associated with acronym FRIENDS): 

the  presence  of  a foreign  body  within  the  tract  or  adjacent  to  it,  previous radiation  exposure  of  the  site,  ongoing  inflammation (most  commonly  from  Crohn  disease)  or  infection  that contributes  to  a  catabolic  state,  epithelialization  of  the fistula  tract  (particularly  if  the  fistula  tract  is  less  than 2  cm  long),  neoplasm,  distal  intestinal  obstruction,  and  pharmacologic  doses  of  steroids. 

Fistulas  associated  with  a concurrent  pancreatic  fistula  also  have  a  low  rate  of  spontaneous  closure,  as  do  those  occurring  in  the  presence  of  malnutrition  or  adjacent  infection.

In general,  anatomic  locations  that  are  favorable  for  closure  are  the  oropharynx,  esophagus,  duodenal  stump,  pancreas,  biliary  tree,  and  jejunum.

Investigations in lower GI Bleed

Investigations in lower GI Bleed

Q Least useful investigation in a pt with recurrent LGI bleed, multiple upper and lower GI endoscopies negative


b) Double balloon enteroscopy

c) Capsule endoscopy

d) Push endoscopy


Free for all


Investigations in lower GI bleed should be specific and less time consuming

Small bowel enteroclysis, which uses a tube to infuse barium, methylcellulose, and air directly into the small bowel, yields better images than simple small bowel follow-through. Because the yield has been reported to be very low and the test is poorly tolerated, it is now rarely used.

Capsule endoscopy uses a small capsule with a video camera. capsule endoscopy is an excellent tool for the patient who is hemodynamically stable but continues to bleed, with reported  success  rates  as  high  as  90%  in  identifying  a  small bowel  pathology.

The hemodynamically stable patient should undergo small bowel enteroscopy. Usually performed with a pediatric colonoscope, it is referred to as push endoscopy. It can reach about 50 to 70 cm past the ligament of Treitz  in most cases and permits endoscopic management of some lesions. Overall, push enteroscopy is successful in 40% of patients .

Double-balloon endoscopy is another technique gaining in popularity. Although technically difficult, this approach is capable of providing a complete examination of the small bowel. In expert hands, double-balloon enteroscopy can identify a bleeding source in 77% of cases with occult bleeding, with the yield increasing to over 85% if the endoscopy is per-formed within 1 month of an overt bleeding episode.The advantage of this technique is that as well as visualization,  biopsies can be performed and therapeutic interventions undertaken.

To conclude investigations in lower GI bleed have to be specific and have high sensitivity also.
