Pancreatic Trauma Indian Medical PG Practice Questions and MCQs
Question 1: Which of the following is the LEAST likely indication for surgical intervention in pancreatic ascites?
- A. Persistent symptoms despite conservative management (Correct Answer)
- B. Recurrent ascites with significant symptoms
- C. Failure of medical management
- D. Leak from the stented duct
Explanation: ***Persistent symptoms despite conservative management*** - This is the **LEAST likely indication** because it is vague and non-specific compared to the other options - Conservative management for pancreatic ascites (including bowel rest, TPN, somatostatin analogues) typically requires **4-6 weeks to assess efficacy** - "Persistent symptoms" alone does not constitute a surgical indication unless accompanied by **specific complications** or **documented failure** of conservative therapy - Surgery is considered only after clear evidence of treatment failure, not merely symptom persistence during the trial period *Recurrent ascites with significant symptoms* - **Recurrence of ascites** after initial control indicates failure of conservative or endoscopic management - Significant symptoms (abdominal distension, pain, respiratory compromise, malnutrition) with recurrence are a **strong indication for surgical intervention** - Suggests underlying pancreatic duct disruption that requires definitive surgical repair *Failure of medical management* - **Clear failure of medical management** is a **primary indication for surgery** in pancreatic ascites - Includes failure to control ascites with octreotide, TPN, repeated paracentesis, and bowel rest - Indicates need for surgical approaches such as internal drainage, resection, or duct repair *Leak from the stented duct* - A **leak from a stented pancreatic duct** represents **failure of endoscopic therapy** - This is a **direct and specific indication** for surgical intervention - Ongoing pancreatic fluid leakage despite stenting requires surgical repair to prevent complications such as infection, malnutrition, and persistent fluid collections
Question 2: What is the investigation of choice for blunt abdominal trauma in an unstable patient?
- A. X-ray abdomen
- B. MRI
- C. USG (Correct Answer)
- D. Diagnostic Peritoneal Lavage (DPL)
Explanation: ***USG (FAST Exam)*** - In an **unstable patient** with blunt abdominal trauma, **Focused Assessment with Sonography for Trauma (FAST) exam** is the investigation of choice. - It is **rapid, non-invasive, and bedside**, allowing immediate detection of **free fluid** (blood) in the peritoneal cavity, pericardium, and pleural spaces without transporting the patient. - Guides immediate decision for **laparotomy** in hemodynamically unstable patients. - **Note:** In **stable patients**, **CT abdomen** is the gold standard as it provides detailed anatomical information, but it requires patient transport and time. *X-ray abdomen* - Provides limited information in blunt trauma, primarily showing **free air** (bowel perforation) or **bony fractures**. - **Not sensitive** for detecting intraperitoneal bleeding, which is the primary concern in unstable patients. *MRI* - Offers excellent soft tissue detail but is **time-consuming** and requires the patient to be **hemodynamically stable**. - **Impractical** for unstable trauma patients requiring rapid assessment and intervention. *Diagnostic Peritoneal Lavage (DPL)* - An **invasive procedure** that is sensitive for detecting intra-abdominal hemorrhage. - Has largely been **replaced by FAST exam** in most trauma centers due to FAST being non-invasive, rapid, and repeatable. - DPL has a **higher false-positive rate** and cannot identify the source of bleeding.
Question 3: 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
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.
Question 4: Pancreatitis is a common complication of which one of the following?
- A. Zidovudine
- B. Zalcitabine
- C. Stavudine
- D. Didanosine (ddI) (Correct Answer)
Explanation: ***Didanosine (ddI)*** - **Didanosine (ddI)** is a nucleoside reverse transcriptase inhibitor (NRTI) known for causing dose-dependent **pancreatitis** as a significant adverse effect. - Patients on didanosine require monitoring for symptoms and elevated **amylase/lipase** levels. *Zidovudine* - **Zidovudine** (AZT) is an NRTI primarily associated with **bone marrow suppression** (anemia, neutropenia) and myopathy. - While it can cause lactic acidosis, **pancreatitis** is not its most common or dose-limiting side effect. *Zalcitabine* - **Zalcitabine** (ddC) is an NRTI whose primary dose-limiting toxicity is **peripheral neuropathy**, particularly in the extremities. - **Pancreatitis** is a less common adverse effect compared to didanosine. *Stavudine* - **Stavudine** (d4T) is an NRTI frequently associated with **peripheral neuropathy** and **lipoatrophy** (loss of subcutaneous fat). - Although it can also contribute to lactic acidosis, **pancreatitis** is not its characteristic or most common side effect.
Question 5: 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
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.
Question 6: What is the median survival time for patients with carcinoma of the pancreas after surgery and adjuvant therapy?
- A. Approximately 12 months
- B. Approximately 32 months
- C. Approximately 22 months (Correct Answer)
- D. Approximately 44 months
Explanation: ***Approximately 22 months*** - The median survival for patients with **resectable pancreatic adenocarcinoma** treated with surgery (typically pancreaticoduodenectomy) and adjuvant chemotherapy is approximately **22-28 months** based on contemporary studies. - The 22-month figure represents a well-established median from multiple clinical trials including **ESPAC-1 and CONKO-001**, making it the most representative answer among the options provided. - This outcome reflects significant improvement from the pre-adjuvant therapy era but still underscores the aggressive biology of pancreatic cancer. *Approximately 12 months* - This figure represents **historical median survival** prior to the routine use of effective adjuvant chemotherapy, or survival in patients with **unresectable locally advanced disease** treated with palliative chemotherapy alone. - It is **not representative** of outcomes in patients who undergo complete surgical resection followed by modern adjuvant therapy. *Approximately 32 months* - While highly selected patients with **favorable tumor biology** (small tumors, negative margins, low CA 19-9) and optimal response to modern regimens like **FOLFIRINOX** may approach this survival, it exceeds the **median survival** for the general population of resected patients. - This represents the upper quartile rather than the median outcome. *Approximately 44 months* - This exceptionally long survival is **not achieved** as a median in pancreatic ductal adenocarcinoma, even with optimal surgical resection and adjuvant therapy. - Such prolonged survival is occasionally seen in **highly selected patients** or with less aggressive pancreatic neoplasms (e.g., neuroendocrine tumors, intraductal papillary mucinous neoplasms with invasive component), which have substantially better prognoses than typical ductal adenocarcinoma.
Question 7: 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
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.
Question 8: After pancreaticoduodenectomy (PD surgery), when should the first postoperative follow-up visit be scheduled to assess the patient's recovery?
- A. 3 weeks
- B. 4 weeks
- C. 1 week
- D. 2 weeks (Correct Answer)
Explanation: ***2 weeks*** - A 2-week recall after **pancreaticoduodenectomy (PD surgery)** allows sufficient time for early postoperative complications to manifest while still being within a window for timely intervention. - This timeframe enables assessment of **wound healing**, resolution of ileus, nutritional status, and early recognition of issues like **pancreatic fistula** or **delayed gastric emptying**. *1 week* - A 1-week recall might be too early to identify some significant complications that typically present slightly later, such as **pancreatic fistula**. - At this stage, patients are often still in the acute recovery phase, making comprehensive outpatient assessment less informative. *3 weeks* - Delaying recall until 3 weeks might be too late for optimal management of certain **postoperative complications**, potentially leading to more severe outcomes. - Early symptoms of complications could be missed, increasing the risk of re-admission or prolonged recovery. *4 weeks* - By 4 weeks, many **early complications** that require timely intervention may have become more advanced or difficult to manage. - This recall period is often used for a more routine follow-up rather than immediate assessment of acute recovery.
Question 9: A 65-year-old patient presents with obstructive jaundice and 15 kg weight loss. An ultrasound shows a 4 cm mass in the head of the pancreas with dilated bile ducts. Further work up includes a helical CT scan. The study shows several lesions consistent with metastasis in the right and left lobes of the liver and encasement of gastroduodenal artery. The most appropriate treatment would be:
- A. Total pancreatectomy
- B. Biliary and gastric bypass
- C. Pancreaticoduodenectomy (Whipple procedure)
- D. Endoscopic stenting of bile duct (Correct Answer)
Explanation: **_Endoscopic stenting of bile duct_** - The presence of **distant liver metastases** and **vascular encasement** makes the disease inoperable and renders curative surgery impossible. - **Endoscopic stenting** offers effective palliation for **obstructive jaundice**, improving quality of life by relieving symptoms such as itching and nausea, and preventing cholangitis. *Total pancreatectomy* - This is an **extensive surgical procedure** suitable for resectable pancreatic head tumors without metastatic disease. - It is **highly morbid** and not indicated in the presence of **liver metastases** and **vascular encasement**, as it would not be curative and carries significant risks. *Biliary and gastric bypass* - This procedure aims to relieve both **biliary obstruction** and potential gastric outlet obstruction, which can occur from pancreatic head tumors. - While it addresses symptoms, it is still a **surgical intervention** with associated risks and is generally reserved for patients with a longer life expectancy or when endoscopic stenting is unsuccessful or unfeasible. It is not the most appropriate initial palliative step given the metastatic disease. *Pancreaticoduodenectomy (Whipple procedure)* - The **Whipple procedure** is the standard curative surgical treatment for **resectable pancreatic head cancers**. - However, the patient's presentation with **liver metastases** and **gastroduodenal artery encasement** indicates unresectable disease, making this procedure inappropriate and potentially harmful.
Question 10: All are true about Whipple procedure except?
- A. Removes the head of pancreas
- B. Removes the entire duodenum
- C. Removes the gallbladder
- D. Removes the tail of pancreas (Correct Answer)
Explanation: ***Correct: Removes the tail of pancreas*** - The Whipple procedure (pancreaticoduodenectomy) **does NOT remove the tail of pancreas** - Only the **head of the pancreas** is resected - The tail and body of pancreas are **preserved** in a standard Whipple procedure - Removal of tail would be done in **distal pancreatectomy**, not Whipple *Incorrect: Removes the head of pancreas* - This is **TRUE** - the head of pancreas is always removed in Whipple procedure - This is the primary pancreatic component resected *Incorrect: Removes the entire duodenum* - This is **TRUE** - the entire duodenum is removed en bloc with pancreatic head - D1, D2, D3, and D4 portions are all resected *Incorrect: Removes the gallbladder* - This is **TRUE** - cholecystectomy is a standard component of Whipple procedure - The gallbladder and distal common bile duct are routinely removed
