Paraneoplastic syndrome in HCC

admin

Q) Paraneoplastic Syndrome in HCC which also occurs in End stage liver disease

a) Hypercholesteremia

b) Hypoglycemia

c) Hypercalcemia

d) Carcinoid

Ans -  b

Hypoglycemia (also seen in end stage liver disease) 

Erythrocytosis

Timing of cholecystectomy in biliary pancreatitis

admin

Q) What is true regarding timing of cholecystectomy in biliary pancreatitis

a) Cholecystectomy should be done before discharge in severe pancreatitis to prevent recurrent attacks

b) Cholecystectomy should be done in same admission as pancreatitis when severe disease is excluded

c) Early cholecystectomy has been shown to have more complications than interval choelcystectomy

d) Early cholecystectomy increases technical complications

 Ans b

"Poncho trial " answers this question

Early  cholecystectomy (just before discharge, when the patient has recovered and severe disease excluded), compared to interval cholecystectomy, effectively reduces

  1. The rate of recurrent gallstone-related complications in patients with mild biliary pancreatitis,
  2. low added risk of complications.

Evidence on the timing of cholecystectomy in severe pancreatitis is scarce. Cholecystectomy is recommended after all signs of pancreatic necrosis have been resolved or if they persist more than 6 weeks

Skin grafting

admin

Q)In preop evaluation before placing skin graft over wounded area…bacterial colony count must be less than
a) 10000
b) 100000
c) 1000000
d) 10000000

ans b)  10 raise to the power 5

Prerequisites for skin grafting:
The recipient site should be assessed for potential bacterial load, blood supply,
presence of devitalized tissue, and exposed vital structures.
Donor site availability
Perform recipient site tissue culture if history or concern for infection (counts <105
CFU/g tissue for most pathogens required before grafting).
Presence of group a beta heamolytic streptococci is absolute contraindication for
skin grafting

Highly selective vagotomy

admin
Q) False about highly selective vagotomy
a) Highly selective vagotomy divides the vagus nerves supplying the acid-producing portion of the stomach
b) Incidence of postoperative complications is lower.
c) The criminal nerve of Grassi should be severed
d) Crow's feet nerves are severed till below the GE junction

 

 Ans -d

HSV only divides the last part of the nerves which supply the part of stomach which produces acid
Acnt and post nerves of Latarjet are found and their terminal branches are severed from 7 cm proximal to the pylorus to 5 cm above the GE junction
Motor function of the stomach is not affected
Criminal nerve of grassi is branch of posterior vagus. It should be sought and cut

Post Whipple’s Bleeding

admin

Q) Post whipples on pod4 patient presented with fever, tachycardia and pain, usg showed collection, which was drained percutaneously. on pod 10 there is frank blood of 100ml in drain, next line of management

a. Ct angiography

b. Emergency laparotomy

c. flush the drain with noradrenaline
d. Observe

Ans a 

This is extraluminal bleed on 10th POD following most likely a pancreatic fistula. Clinical condition is mentioned for day 4 which is  because of pancreatic leak.  A pancreatic fistula can cause vascular pseudo aneurysm so answer is A CT angiography

Early extraluminal PPH requires reexploration.

Intraluminal bleeding may manifest as extraluminal if there is associated anastomotic breakdown,and this may be amenable to angiographic intervention when involving the pancreaticojejunostomy.

Patients present with septic complications and/or a sentinel  bleed. Radiographic embolization has become a more successful modality, with up to 80% success,13 but is limited by the initially intermittent nature of the bleeding

Exploration - if patient is not stable

Tumor lysis syndrome

admin

Q)Tumor lysis  syndrome which is not seen

a. hyperkalemia

b hypocalcemia

c. hypophosphatemia

d. hyperuricemia

Ans is c

Tumor lysis syndrome releases, various intracellular  metabolites such as uric acid, potassium and phosphorous which overwhelm the excretory capacities of the kidney.

The metabolic anomalies are

Hyperuricemia

Hyperkalemia

Hyperphosphatemeia

Hypocalcemia

It mostly occurs in poorly differentiated leukemias and lymphomas

Corrosive Stricture esophagus

admin

Q) Which has no part in management of corrosive injury of esophagus?

a) Repeated Endoscopies routinely

b) Esophagectomy in some cases

c) Early emergency surgery routinely

d) Steroid use routinely

C

Other than the need for emergency surgery for bleeding or perforation, elective oesophageal resection should be deferred for at least 3 months until the fibrotic phase has been established.

Oesophageal replacement is usually required for very long or multiple strictures. Resection can be difficult because of perioesophageal inflammation in these patients.

Regular endoscopic examinations are the best way to assess stricture development (Figure 62.12). Significant stricture formation occurs in about 50% of patients with extensive mucosal damageo Corrosives can cause significant pharyngolaryngeal oedema

In unusual circumstances, e.g. with extensive necrosis after corrosive ingestion, emergency oesophagectomy may be necessary.

Haemorrhoidectomy

admin

Q) Not an indiction of haemorrhoidectomy 

a) Persistent Second degree haemorrhoid 5 days after sclerotherapy

b) 3rd degree haemorrhoid

c) Fibrosed  haemorrhoid

d)  interno-external haemorrhoids when the external haemorrhoid is well defined.

Ans a

haemorrhoids can persist for 10 days after sclerotherapy

The indications for haemorrhoidectomy include:

● third- and fourth-degree haemorrhoids;

● second-degree haemorrhoids that have not been cured by non-operative treatments;

● fibrosed haemorrhoids;

● interno-external haemorrhoids when the external haemorrhoid is well defined.

Four degrees of haemorrhoids ●●

First degree – bleed only, no prolapse ●●

Second degree – prolapse but reduce spontaneously ●●

Third degree – prolapse and have to be manually reduced ●●

Fourth degree – permanently prolapsed

Pseudo achalasia

admin

Q) Most common cause of  pseudo achalasia is ?

(a) Benign tumors of esophagus
(b) Chagas disease
(c) Caustic injury
(d) Adenocarcinoma of cardia

Answer free for all 

d

Pseudoachalasia is an achalasia-like disorder that is usually produced by adenocarcinoma of the cardia
Other uncommon causes are
