Pancreatic Pseudocysts Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Pancreatic Pseudocysts. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Pancreatic Pseudocysts Indian Medical PG Question 1: All are true about pseudopancreatic cyst of pancreas except:
- A. Common after acute pancreatitis
- B. Serum amylase is increased
- C. Most common site is in head of pancreas (Correct Answer)
- D. Presents as an abdominal mass
Pancreatic Pseudocysts Explanation: ***Most common site is in head of pancreas***
- The **body and tail of the pancreas** are the most common sites for pseudocysts due to the typical location of pancreatic inflammation and fluid accumulation.
- While pseudocysts can theoretically occur anywhere, the head is less frequently affected as the primary site.
*Common after acute pancreatitis*
- **Pancreatic pseudocysts** are a frequent complication, occurring in about 10-20% of patients following an episode of **acute pancreatitis** [1].
- They form when pancreatic fluid, rich in enzymes, leaks and becomes walled off by granulation tissue.
*Presents as an abdominal mass*
- Depending on its size and location, a **pseudocyst** can present as a palpable and sometimes painful **abdominal mass**.
- Larger pseudocysts can cause symptoms by compressing adjacent organs [1].
*Serum amylase is increased*
- Although the acute phase of pancreatitis has resolved, some **leakage of pancreatic enzymes** into the peritoneum or bloodstream can persist, leading to elevated **serum amylase** levels.
- This elevation reflects the ongoing enzymatic activity within the pseudocyst.
Pancreatic Pseudocysts Indian Medical PG Question 2: Which of the following is NOT a recommended management strategy for acute pancreatitis?
- A. Antibiotics are required only in cases of infected necrosis.
- B. Prolonged withholding of oral intake (Correct Answer)
- C. IV fluids are essential
- D. Early enteral feeding is preferred
Pancreatic Pseudocysts Explanation: ***Prolonged withholding of oral intake***
- Historically, prolonged fasting was common for **pancreatic rest**, but current evidence supports early refeeding.
- **Early refeeding** (within 24-72 hours) is now recommended as it can prevent complications like gut atrophy and bacterial translocation.
*Antibiotics are required only in cases of infected necrosis.*
- Prophylactic antibiotics are **not recommended** in acute pancreatitis due to lack of benefit and potential to increase multi-drug resistant infections.
- Antibiotics should be reserved for cases of **proven or suspected infected pancreatic necrosis**, indicated by gas on CT or positive culture from fine-needle aspiration [1].
*IV fluids are essential*
- **Aggressive intravenous fluid resuscitation** is crucial, especially in the early stages, to maintain pancreatic and organ perfusion and prevent systemic complications [2].
- Initial boluses followed by continuous infusion, targeting markers like heart rate and urine output, are standard to correct **hypovolemia**.
*Early enteral feeding is preferred*
- **Early enteral nutrition** (usually via nasojejunal tube if oral feeding is not tolerated) is preferred over parenteral nutrition.
- This helps maintain gut integrity, prevents bacterial translocation, and is associated with **fewer complications** like infection and overall shorter hospital stay.
Pancreatic Pseudocysts Indian Medical PG Question 3: Most common complication of a pseudocyst of the pancreas is
- A. Rupture into peritoneum
- B. Haemorrhage
- C. Infection (Correct Answer)
- D. Rupture into colon
Pancreatic Pseudocysts Explanation: ***Infection***
- **Infection** is the most common and clinically significant complication of a pancreatic pseudocyst, often leading to sepsis and increased mortality.
- While other complications can occur, **secondary infection** transforms a sterile pseudocyst into an abscess, requiring urgent intervention.
*Rupture into peritoneum*
- While possible, **rupture into the peritoneum** (free rupture) is a less frequent complication compared to infection.
- This leads to acute peritonitis and is a highly morbid event, but statistically less common than infection.
*Haemorrhage*
- **Hemorrhage** (bleeding) into a pseudocyst is a serious and potentially life-threatening complication, but it is less common than infection.
- It usually results from erosion into adjacent blood vessels, such as the splenic or gastroduodenal arteries.
*Rupture into colon*
- **Rupture into the colon** or other adjacent organs (like the stomach or duodenum) can occur, but these are less frequent compared to infection.
- Such ruptures can lead to internal fistula formation, but infection remains the predominant complication.
Pancreatic Pseudocysts Indian Medical PG Question 4: A 45 year old lawyer presents with pain in the abdomen more so in the epigastric region that worsens with eating spicy food and is relieved by bending forward. Complications of the above mentioned condition could be all except:
- A. Splenic Vein Thrombosis (Correct Answer)
- B. Bleeding
- C. Gastric Outlet Obstruction
- D. Perforation
Pancreatic Pseudocysts Explanation: ***Splenic Vein Thrombosis***
- The patient's symptoms (epigastric pain worsening with spicy food, relieved by bending forward) are highly suggestive of **pancreatitis**, not peptic ulcer disease [1]. **Splenic vein thrombosis** is a known complication of chronic pancreatitis due to inflammation and compression of the splenic vein [2].
- While pancreatitis can cause significant morbidity, **splenic vein thrombosis** is a specific vascular complication associated with prolonged inflammation of the pancreas, leading to localized portal hypertension and potentially isolated gastric varices.
*Perforation*
- **Perforation** (specifically of a peptic ulcer or potentially surrounding bowel in severe pancreatitis) is a severe complication that can occur in conditions causing abdominal pain, but it is not the *exception* among the given options for the likely underlying condition indicated by the patient's symptoms (pancreatitis) [3].
- This complication typically leads to **peritonitis**, a medical emergency requiring immediate surgical intervention [3].
*Bleeding*
- **Bleeding** (e.g., from a pancreatic pseudocyst rupturing into the gastrointestinal tract or from localized varices secondary to portal hypertension in pancreatitis) is a recognized complication of the patient's likely underlying condition [1].
- Gastrointestinal bleeding can also result from **gastric erosions** or ulcers exacerbated by ongoing inflammation.
*Gastric Outlet Obstruction*
- **Gastric outlet obstruction** can occur as a complication of severe or chronic pancreatitis, often due to **inflammation**, **fibrosis**, or **pseudocyst formation** compressing the duodenum [1].
- This typically presents with **postprandial vomiting** and early satiety, which can arise in the context of chronic pancreatic inflammation.
Pancreatic Pseudocysts Indian Medical PG Question 5: The following procedure is performed for the management of?
- A. Gallbladder carcinoma
- B. Distal cholangiocarcinoma (Correct Answer)
- C. Chronic calcific pancreatitis
- D. Advanced gastric carcinoma
Pancreatic Pseudocysts Explanation: ***Distal cholangiocarcinoma***
- The image shows a **Pylorus-preserving Whipple procedure (PPPD)**, which involves resection of the pancreatic head, duodenum, gallbladder, and part of the common bile duct, followed by reconstruction.
- This procedure is primarily performed for malignancies of the **pancreatic head**, **distal bile duct (cholangiocarcinoma)**, and **ampulla of Vater**, as they often cause obstructive jaundice and are resectable.
*Gallbladder carcinoma*
- While gallbladder carcinoma can involve the bile ducts, this specific reconstruction (PPPD) is more commonly associated with tumors of the pancreatic head or distal bile duct rather than the gallbladder itself, which might be managed with a **cholecystectomy** and possibly **liver resection**.
- The type of resection and reconstruction varies significantly based on the extent and location of gallbladder cancer.
*Chronic calcific pancreatitis*
- Surgical management for chronic pancreatitis, especially with calcifications, typically involves drainage procedures (e.g., **Puestow procedure** due to dilated pancreatic duct or **Frey procedure**) or resection of the pancreatic head (e.g., **Beger procedure**).
- While some resections of the pancreatic head are performed for chronic pancreatitis, the depicted procedure is specifically designed for malignancies of the pancreatic head region, not primarily for the sequelae of chronic calcific pancreatitis unless associated with a mass suspicious for malignancy.
*Advanced gastric carcinoma*
- Advanced gastric carcinoma is typically managed by **gastrectomy** (partial or total) with lymphadenectomy, not a Whipple procedure.
- The image clearly shows an **intact pylorus** and the stomach mostly preserved, which is inconsistent with advanced gastric carcinoma requiring major gastric resection.
Pancreatic Pseudocysts Indian Medical PG Question 6: A 50-year-old chronic alcoholic presents to the emergency room with 12 hours of severe abdominal pain. The pain radiates to the back and is associated with an urge to vomit. Physical examination discloses exquisite abdominal tenderness. Laboratory studies show elevated serum amylase. Which of the following morphologic changes would be expected in the peripancreatic tissue of this patient?
- A. Caseous necrosis
- B. Fibrinoid necrosis
- C. Fat necrosis (Correct Answer)
- D. Coagulative necrosis
Pancreatic Pseudocysts Explanation: ***Fat necrosis***
- The patient's presentation with **severe abdominal pain radiating to the back**, **elevated serum amylase**, and **history of chronic alcoholism** is highly suggestive of **acute pancreatitis** [2], [3].
- **Fat necrosis** is a characteristic morphologic change in **acute pancreatitis**, occurring when activated pancreatic enzymes (especially **lipases**) leak into the peripancreatic tissue and break down fat, leading to the formation of **calcium soaps** [1].
*Caseous necrosis*
- This type of necrosis is typically associated with **granulomatous inflammation**, most commonly seen in **tuberculosis** [1].
- It results in a **cheese-like appearance** and is not characteristic of pancreatic injury from acute pancreatitis [1].
*Fibrinoid necrosis*
- **Fibrinoid necrosis** involves damage to **blood vessel walls**, where plasma proteins (including fibrin) leak into the vessel wall, appearing amorphous and eosinophilic.
- It is typically seen in **immunologic diseases** (e.g., vasculitis) or severe hypertension, not acute pancreatitis.
*Coagulative necrosis*
- This type of necrosis is classically caused by **ischemia** (e.g., myocardial infarction, renal infarction), where cell outlines are preserved for a period due to the denaturation of structural proteins and enzymes.
- While ischemia can lead to pancreatic damage, the primary and distinctive form of necrosis in peripancreatic fat during acute pancreatitis is **fat necrosis**.

Pancreatic Pseudocysts Indian Medical PG Question 7: Which of the following is not a recognized complication of chronic pancreatitis?
- A. Renal artery thrombosis (Correct Answer)
- B. Pancreatic pseudocyst
- C. Splenic vein thrombosis
- D. Pancreatic fistula
Pancreatic Pseudocysts Explanation: ***Renal artery thrombosis***
- **Renal artery thrombosis** is generally associated with conditions like **atherosclerosis**, atrial fibrillation, or vasculitis, not directly with chronic pancreatitis.
- While chronic pancreatitis can lead to systemic complications, direct renal arterial clotting is an atypical and **uncommon sequela**.
*Pancreatic pseudocyst*
- **Pancreatic pseudocysts** are common complications of chronic pancreatitis, occurring when fluid collections around the pancreas become walled off by fibrous tissue [1].
- They can cause pain, obstruction, and even rupture if left untreated [2].
*Splenic vein thrombosis*
- **Splenic vein thrombosis** can result from inflammation and compression of the splenic vein by the diseased pancreatic tissue in chronic pancreatitis [1].
- This can lead to **splenomegaly** and **gastric varices** due to increased pressure in the portal system.
*Pancreatic fistula*
- A **pancreatic fistula** occurs when pancreatic fluid leaks from the gland, often forming a connection to another organ or the skin [2].
- This is a well-recognized complication of both acute and chronic pancreatitis, usually due to ductal disruption.
Pancreatic Pseudocysts Indian Medical PG Question 8: A chronic alcoholic patient came to emergency with severe pain in epigastrium and multiple episodes of vomiting. On examination, guarding was present in upper epigastrium. Chest X-ray was normal. What is the next best step?
- A. CECT
- B. Alcohol breath test
- C. Serum lipase (Correct Answer)
- D. Upper GI endoscopy
Pancreatic Pseudocysts Explanation: ***Serum lipase***
- The patient's presentation with acute epigastric pain, vomiting, guarding, and a history of chronic alcoholism strongly suggests **acute pancreatitis** [1].
- **Serum lipase** is highly sensitive and specific for diagnosing acute pancreatitis, with levels typically elevated to at least three times the upper limit of normal.
*CECT*
- While **CECT (Contrast-Enhanced Computed Tomography)** is excellent for assessing the severity and complications of pancreatitis, it is generally not the initial diagnostic test for suspected acute pancreatitis [1].
- CT scans are usually performed if the diagnosis is unclear or if complications like **necrosis** or **fluid collections** are suspected after initial laboratory tests.
*Alcohol breath test*
- An **alcohol breath test** would confirm recent alcohol consumption but does not directly diagnose the cause of the patient's acute abdominal pain [2].
- While chronic alcoholism is a risk factor for pancreatitis, this test does not provide specific information about the underlying medical emergency.
*Upper GI endoscopy*
- **Upper GI endoscopy** is primarily used to evaluate conditions affecting the esophagus, stomach, and duodenum, such as **ulcers** or **gastritis**.
- It would not be the initial diagnostic step for suspected pancreatitis, as it does not directly visualize the pancreas and carries risks in an acutely ill patient.
Pancreatic Pseudocysts Indian Medical PG Question 9: Pancreatic pseudocysts developing complications are best managed by?
- A. Conservative treatment
- B. Surgery (Correct Answer)
- C. Radiologically guided interventions
- D. External drainage
Pancreatic Pseudocysts Explanation: ***Surgery***
- When pancreatic pseudocysts develop **complications** (infection, hemorrhage, rupture, gastric outlet/biliary obstruction), definitive management is required.
- Surgical internal drainage procedures (**cyst-gastrostomy**, **cyst-jejunostomy**, or **cyst-duodenostomy**) provide durable treatment by creating a permanent communication between the mature pseudocyst and the GI tract.
- Surgery is particularly indicated when the pseudocyst has a **mature wall (>6 weeks)**, is **large (>6 cm)**, or when endoscopic approaches are not feasible or have failed.
- While endoscopic drainage (EUS-guided) is increasingly used as first-line therapy, surgery remains the gold standard for complicated pseudocysts requiring definitive management, especially with complex anatomy or failed minimally invasive approaches.
*Conservative treatment*
- Conservative management with observation, pain control, and nutritional support is appropriate only for **asymptomatic, small (<6 cm)**, and **uncomplicated pseudocysts** with high likelihood of spontaneous resolution.
- Once complications develop, conservative treatment is **inadequate** and poses risks of further deterioration.
*Radiologically guided interventions*
- Percutaneous drainage may be used for **infected pseudocysts** or as a temporizing measure, but carries high risk of **external fistula formation** (25-50%) and **recurrence**.
- Does not provide internal drainage and is generally less effective than surgical or endoscopic internal drainage for complicated pseudocysts.
- Not considered definitive management when complications are present.
*External drainage*
- External percutaneous catheter drainage is primarily a **temporizing measure** for critically ill patients or infected pseudocysts not amenable to other approaches.
- High risk of **pancreaticocutaneous fistula** formation and does not address the underlying pancreatic duct communication.
- Requires subsequent definitive management in most cases; not appropriate as primary treatment for complicated pseudocysts.
Pancreatic Pseudocysts Indian Medical PG Question 10: In acute pancreatitis, surgery is indicated in which one of the following conditions?
- A. Infected pancreatic necrosis (Correct Answer)
- B. Acute pseudocyst
- C. Acute fluid collection
- D. Sterile pancreatic necrosis
Pancreatic Pseudocysts Explanation: ***Infected pancreatic necrosis***
- **Infected pancreatic necrosis** is a severe complication of acute pancreatitis requiring surgical or percutaneous debridement (necrosectomy) to remove infected tissue and prevent sepsis.
- The presence of infection in necrotic tissue significantly increases morbidity and mortality, making intervention crucial.
*Acute pseudocyst*
- An acute pseudocyst is usually managed conservatively and only requires intervention if it is **symptomatic**, rapidly expanding, or becomes infected.
- Surgical drainage is typically reserved for large, symptomatic, or complicated pseudocysts that persist beyond 6 weeks.
*Acute fluid collection*
- **Acute fluid collections** are generally self-limiting and resolve without intervention.
- They are typically asymptomatic and represent an early stage of fluid accumulation, often preceding pseudocyst formation.
*Sterile pancreatic necrosis*
- **Sterile pancreatic necrosis** is usually managed with supportive care, as surgical intervention in the absence of infection does not improve outcomes and may increase complications.
- The key distinction is the absence of infection—surgery is indicated only when necrosis becomes infected.
