Palliative surgical procedures US Medical PG Practice Questions and MCQs
Practice US Medical PG questions for Palliative surgical procedures. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Palliative surgical procedures US Medical PG Question 1: A 53-year-old woman comes to the emergency department because of weakness and abdominal pain for 24 hours. She has had three bowel movements with dark stool during this period. She has not had vomiting and has never had such episodes in the past. She underwent a tubal ligation 15 years ago. She has chronic lower extremity lymphedema, osteoarthritis, and type 2 diabetes mellitus. Her father died of colon cancer at the age of 72 years. Current medications include metformin, naproxen, and calcium with vitamin D3. She had a screening colonoscopy at 50 years of age which was normal. She appears pale and diaphoretic. Her temperature is 36°C (96.8°F), pulse is 110/min, respirations are 20/min, and blood pressure is 90/50 mm Hg. Pulse oximetry on room air shows an oxygen saturation of 98%. The abdomen is soft and nondistended with mild epigastric tenderness. Rectal exam shows tarry stool. Two large bore IV lines are placed and fluid resuscitation with normal saline is initiated. Which of the following is the most appropriate next step in management?
- A. Esophagogastroduodenoscopy (Correct Answer)
- B. CT scan of the abdomen with contrast
- C. Flexible sigmoidoscopy
- D. Diagnostic laparoscopy
- E. Colonoscopy
Palliative surgical procedures Explanation: ***Esophagogastroduodenoscopy***
- The patient presents with symptoms highly suggestive of an **upper GI bleed**, including **melena (dark, tarry stools)**, weakness, abdominal pain, and signs of **hemodynamic instability** (tachycardia, hypotension, pallor, diaphoresis).
- An EGD is the **most appropriate initial diagnostic and therapeutic procedure** for suspected upper GI bleeding, allowing for direct visualization, diagnosis of the source (e.g., peptic ulcer, esophagitis, varices), and immediate intervention (e.g., endoscopic hemostasis).
*CT scan of the abdomen with contrast*
- A CT scan is not the first-line investigation for acute GI bleeding because it is generally less sensitive than endoscopy for active bleeding and does not allow for immediate therapeutic intervention.
- While it can identify some causes of GI bleeding, such as tumors or vascular malformations, it is usually reserved for cases where endoscopy is inconclusive or contraindicated.
*Flexible sigmoidoscopy*
- Flexible sigmoidoscopy visualizes only the **rectum and sigmoid colon**, which is insufficient to evaluate the entire colon for a lower GI bleed, and completely misses the upper GI tract.
- Given the tarry stools (melena), an upper GI bleed is far more likely than a lower GI bleed.
*Diagnostic laparoscopy*
- Diagnostic laparoscopy is an invasive surgical procedure used to explore the abdominal cavity for conditions that cause pain or internal bleeding, but it is not the initial diagnostic choice for **GI bleeding**.
- It would expose the patient to unnecessary surgical risks without first attempting less invasive and highly effective endoscopic methods.
*Colonoscopy*
- While a colonoscopy is the gold standard for evaluating the **lower GI tract**, the patient's symptoms (melena, epigastric tenderness) strongly indicate an **upper GI bleed**.
- Performing a colonoscopy first would delay the diagnosis and treatment of a potentially life-threatening upper GI bleed.
Palliative surgical procedures US Medical PG Question 2: A 19-year-old woman is diagnosed with metastatic Ewing sarcoma. She has undergone multiple treatments without improvement. She decides to stop treatment and pursue only palliative care. She is of sound mind and has weighed the benefits and risks of this decision. The patient’s mother objects and insists that treatments be continued. What should be done?
- A. Try to seek additional experimental treatments that are promising.
- B. Follow the wishes of the patient’s mother as she has decision making power for the patient.
- C. Continue treatments until the patient has a psychiatric evaluation.
- D. Continue treatment because otherwise, the patient will die.
- E. Halt treatments and begin palliative care. (Correct Answer)
Palliative surgical procedures Explanation: ***Halt treatments and begin palliative care.***
- An adult patient of **sound mind** has the right to refuse medical treatment, even if that refusal may lead to death. This principle is a cornerstone of **patient autonomy**.
- The patient has clearly expressed her wishes after weighing the benefits and risks, making her decision legally and ethically binding.
*Try to seek additional experimental treatments that are promising.*
- While seeking additional treatments might be an option if the patient desired it, forcing such treatments against her will violates her **autonomy** and right to self-determination.
- The case states the patient has decided to stop treatment, making further treatment exploration against her expressed wishes.
*Follow the wishes of the patient’s mother as she has decision making power for the patient.*
- The patient is 19 years old, making her a **legal adult**, and therefore her mother does not have decision-making power over her medical care.
- The patient's mother's wishes, while understandable from an emotional perspective, do not supersede the **competent adult patient's** right to make her own medical decisions.
*Continue treatments until the patient has a psychiatric evaluation.*
- The patient is described as being of "sound mind" and having "weighed the benefits and risks," indicating she is making an informed decision.
- Requesting a psychiatric evaluation without clear evidence of impaired mental capacity would be a disrespectful and unethical attempt to override her **autonomously made decision**.
*Continue treatment because otherwise, the patient will die.*
- While it is true that stopping treatment will likely lead to death, a **competent adult patient** has the right to refuse life-sustaining treatment.
- The patient's right to **autonomy** and control over her own body takes precedence over the desire of others (including medical professionals or family) to prolong life against her will.
Palliative surgical procedures US Medical PG Question 3: A 62-year-old woman presents to her oncologist to discuss the chemotherapy options for her newly diagnosed breast cancer. During the meeting, they discuss a drug that inhibits the breakdown of mitotic spindles in cells. Her oncologist explains that this will be more toxic to cancer cells because those cells are dividing more rapidly. Which of the following side effects is closely associated with the use of this chemotherapeutic agent?
- A. Photosensitivity
- B. Peripheral neuropathy (Correct Answer)
- C. Paralytic ileus
- D. Hemorrhagic cystitis
- E. Pulmonary fibrosis
Palliative surgical procedures Explanation: ***Peripheral neuropathy***
- Drugs that inhibit the breakdown of **mitotic spindles** are **microtubule-targeting agents** (e.g., **taxanes** like paclitaxel/docetaxel, **vinca alkaloids** like vincristine/vinblastine).
- These agents interfere with **microtubule function** in neurons, leading to **axonal damage** and **peripheral neuropathy**.
- This is the **most characteristic and common dose-limiting toxicity** of microtubule inhibitors, affecting sensory and motor nerves (numbness, tingling, weakness in extremities).
*Photosensitivity*
- **Photosensitivity** is a common adverse effect associated with certain chemotherapeutic agents like **fluorouracil** (5-FU) or **methotrexate**, but is not linked to microtubule inhibitors.
- It involves an increased sensitivity to UV light, often manifesting as a rash or exaggerated sunburn.
*Paralytic ileus*
- **Paralytic ileus** can occur with **vinca alkaloids** (especially vincristine) due to autonomic neuropathy affecting the **enteric nervous system**.
- However, this is **less common** than peripheral neuropathy and occurs more specifically with vincristine rather than taxanes.
- **Peripheral neuropathy** is the more pervasive, dose-limiting, and universally characteristic side effect across all microtubule inhibitors.
*Hemorrhagic cystitis*
- **Hemorrhagic cystitis** is a classic side effect of **alkylating agents** like **cyclophosphamide** and **ifosfamide**, which produce the toxic metabolite **acrolein**.
- It is prevented/managed with **mesna**, which inactivates acrolein.
- Not associated with microtubule inhibitors.
*Pulmonary fibrosis*
- **Pulmonary fibrosis** is a known side effect of certain chemotherapeutic drugs, most notably **bleomycin** and **busulfan**.
- This adverse effect is not associated with agents that target **mitotic spindle breakdown**.
Palliative surgical procedures US Medical PG Question 4: One week after admission to the hospital for an extensive left middle cerebral artery stroke, a 91-year-old woman is unable to communicate, walk, or safely swallow food. She has been without nutrition for the duration of her hospitalization. The patient's sister requests placement of a percutaneous endoscopic gastrostomy tube for nutrition. The patient's husband declines the intervention. There is no living will. Which of the following is the most appropriate course of action by the physician?
- A. Encourage a family meeting (Correct Answer)
- B. Initiate total parenteral nutrition
- C. Consult the hospital ethics committee
- D. Proceed with PEG placement
- E. Transfer to a physician specialized in hospice care
Palliative surgical procedures Explanation: ***Encourage a family meeting***
- In situations of **disagreement among family members** regarding a patient's care, especially when there's no pre-existing expressed wish like a living will, a **family meeting is crucial** to facilitate open communication and achieve consensus.
- This step allows all relevant family members to discuss the patient's best interests, values, and potential wishes, guided by the medical team's input, to determine the most appropriate course of action.
*Initiate total parenteral nutrition*
- Initiating total parenteral nutrition (TPN) is a medical intervention that brings its own risks and benefits and should only be considered after a **clear decision has been made about the patient's long-term nutritional support**.
- TPN is not a solution for family disagreement, and can be more invasive than a PEG for long-term nutrition, and does not directly address the ethical dilemma of conflicting family wishes.
*Consult the hospital ethics committee*
- While an ethics committee consultation may be necessary if a resolution cannot be reached through a family meeting, it is generally considered a **later step** in managing such conflicts.
- The initial priority is to foster communication and consensus among the family members themselves before escalating to an external review body.
*Proceed with PEG placement*
- Proceeding with PEG placement when there is a **direct conflict between immediate family members** (sister versus husband) and no clear advance directive would be inappropriate and could lead to significant ethical and legal challenges.
- Patient autonomy, even through a surrogate, must be respected, and acting unilaterally without resolving the family dispute would be a breach of this principle.
*Transfer to a physician specialized in hospice care*
- Transferring the patient to hospice care implies a decision has been made to focus on comfort care and forego aggressive interventions, which is precisely the point of contention among the family.
- This action would be **premature and inappropriate** as long as there is an unresolved disagreement about the goals of care and whether a PEG should be placed or not.
Palliative surgical procedures US Medical PG Question 5: A previously healthy 37-year-old man comes to the physician for the evaluation of an 8-week history of intermittent burning epigastric pain. During this period, he has also felt bloated and uncomfortable after meals. He has not had weight loss or a change in bowel habits. He has no personal or family history of serious illness. He takes no medications. He does not smoke. He drinks 1–3 beers per week. Vital signs are within normal limits. Abdominal examination shows mild epigastric tenderness on palpation without guarding or rebound tenderness. Bowel sounds are normal. The remainder of the examination shows no abnormalities. Which of the following is the most appropriate next step in management?
- A. Urea breath test (Correct Answer)
- B. Helicobacter pylori eradication therapy
- C. Helicobacter pylori serum IgG
- D. Upper gastrointestinal endoscopy
- E. Proton pump inhibitors
Palliative surgical procedures Explanation: ***Urea breath test***
- The patient presents with classic symptoms of **dyspepsia**, and given his age (<60 years) and absence of **alarm symptoms** (e.g., weight loss, dysphagia, GI bleeding), an initial non-invasive test for **_Helicobacter pylori_** is appropriate.
- A **urea breath test** is a highly sensitive and specific non-invasive method to detect active _H. pylori_ infection.
*Helicobacter pylori eradication therapy*
- This therapy should only be initiated after a confirmed diagnosis of **_H. pylori_ infection**.
- Treating empirically without confirmation can lead to **antibiotic resistance** and unnecessary side effects.
*Helicobacter pylori serum IgG*
- A serum IgG test indicates only **prior exposure** to _H. pylori_ and does not distinguish between active and past infection.
- Therefore, it is **not suitable for diagnosing current active infection** or for confirming eradication.
*Upper gastrointestinal endoscopy*
- **Upper GI endoscopy** is indicated for patients over 60 with new-onset dyspepsia, or for those younger than 60 who present with **alarm symptoms** (e.g., weight loss, dysphagia, recurrent vomiting, GI bleeding, anemia).
- This patient currently has no alarm symptoms, making endoscopy an overly aggressive initial approach.
*Proton pump inhibitors*
- While **PPIs** are effective for symptom relief in dyspepsia, they can mask underlying _H. pylori_ infection or other serious conditions if used empirically without proper investigation.
- Furthermore, PPIs can cause **false-negative results** for _H. pylori_ tests like the urea breath test, so they should ideally be stopped for 1-2 weeks before testing.
Palliative surgical procedures US Medical PG Question 6: A 68-year-old man comes to the emergency department because of sudden onset abdominal pain for 6 hours. On a 10-point scale, he rates the pain as a 8 to 9. The abdominal pain is worst in the right upper quadrant. He has atrial fibrillation and hyperlipidemia. His temperature is 38.7° C (101.7°F), pulse is 110/min, and blood pressure is 146/86 mm Hg. The patient appears acutely ill. Physical examination shows a distended abdomen and tenderness to palpation in all quadrants with guarding, but no rebound. Murphy's sign is positive. Right upper quadrant ultrasound shows thickening of the gallbladder wall, sludging in the gallbladder, and pericolic fat stranding. He is admitted for acute cholecystitis and grants permission for cholecystectomy. His wife is his healthcare power of attorney (POA), but she is out of town on a business trip. He is accompanied today by his brother. After induction and anesthesia, the surgeon removes the gallbladder but also finds a portion of the small intestine is necrotic due to a large thromboembolism occluding a branch of the superior mesenteric artery. The treatment is additional surgery with small bowel resection and thromboendarterectomy. Which of the following is the most appropriate next step in management?
- A. Decrease the patient's sedation until he is able to give consent
- B. Contact the patient's healthcare POA to consent
- C. Proceed with additional surgery without obtaining consent (Correct Answer)
- D. Ask the patient's brother in the waiting room to consent
- E. Close the patient and obtain re-consent for a second operation
Palliative surgical procedures Explanation: ***Proceed with additional surgery without obtaining consent***
- In an **emergency situation** where immediate intervention is required to save a patient's life or prevent serious harm, and the patient **lacks capacity** to consent, explicit consent for additional necessary procedures is not required. The surgeon can proceed based on the principle of **implied consent** in emergencies.
- The discovery of **necrotic small bowel due to thromboembolism** is a life-threatening condition requiring urgent surgical intervention in an already sedated patient, making it an emergency.
*Decrease the patient's sedation until he is able to give consent*
- Decreasing sedation to obtain consent in this critical situation would cause a **dangerous delay** in treating a life-threatening condition (bowel necrosis) and could lead to worsening outcomes or death.
- The patient is **acutely ill** and likely in a state where he cannot grasp information and make decisions, even with reduced sedation, thus true informed consent would be difficult to obtain quickly.
*Contact the patient's healthcare POA to consent*
- Contacting the POA who is out of town would introduce **significant and potentially fatal delays** in treating a rapidly progressing, life-threatening condition.
- While POAs are crucial for non-emergent decision-making, the **principle of preserving life** takes precedence in an acute emergency when a delay would cause irreversible harm.
*Ask the patient's brother in the waiting room to consent*
- The brother is **not the designated healthcare POA** and there is no indication he has legal authority to make medical decisions for the patient.
- Relying on a non-POA family member for consent in an emergency, when the patient's legally appointed surrogate is known, is generally **not the appropriate first step** unless no other option exists and the brother can confirm the patient's wishes from prior discussions, which is not stated.
*Close the patient and obtain re-consent for a second operation*
- Closing the patient and then re-opening for another surgery would expose the patient to **two separate anesthetic events and surgical procedures**, significantly increasing morbidity and mortality risks compared to continuous surgery.
- This option would also introduce an **unacceptable delay** in addressing the acute bowel necrosis, which requires immediate intervention.
Palliative surgical procedures US Medical PG Question 7: A terminally ill patient with advanced cancer requests that no resuscitation be performed in the event of cardiac arrest. The patient is mentally competent and has completed advance directives. A family member later demands full resuscitation efforts. Which of the following is the most appropriate response?
- A. Honor the patient's DNR (Correct Answer)
- B. Obtain court order
- C. Follow the family's wishes
- D. Consult ethics committee
Palliative surgical procedures Explanation: ***Honor the patient's DNR***
- The patient is **mentally competent** and has legally documented their wishes through **advance directives** (DNR), which must be respected.
- A competent patient's right to **autonomy** in making decisions about their medical care takes precedence over the wishes of family members.
*Obtain court order*
- Seeking a court order is **unnecessary** and **inappropriate** when a competent patient's wishes are clearly documented in advance directives.
- This option would cause **undue delay** and legal entanglement, potentially going against the patient's immediate medical needs and preferences.
*Follow the family's wishes*
- Following the family's wishes would **override the patient's autonomy** and legally binding advance directives.
- The family's emotional distress does not negate the patient's right to determine their own medical care, especially when they are competent.
*Consult ethics committee*
- While an ethics committee can be helpful in complex cases with **unclear directives** or patient capacity issues, it's not the first step here.
- The patient's competence and clear advance directives make the decision straightforward; a committee consultation could cause delay and unnecessary burden.
Palliative surgical procedures US Medical PG Question 8: A 66-year-old man comes to the physician because of yellowish discoloration of his eyes and skin, abdominal discomfort, and generalized fatigue for the past 2 weeks. He has had dark urine and pale stools during this period. He has had a 10-kg (22-lb) weight loss since his last visit 6 months ago. He has hypertension. He has smoked one pack of cigarettes daily for 34 years. He drinks three to four beers over the weekends. His only medication is amlodipine. His temperature is 37.3°C (99.1°F), pulse is 89/min, respirations are 14/min, and blood pressure is 114/74 mm Hg. Examination shows jaundice of the sclera and skin and excoriation marks on his trunk and extremities. The lungs are clear to auscultation. The abdomen is soft and nontender. The remainder of the examination shows no abnormalities. Laboratory studies show:
Hemoglobin 12 g/dL
Leukocyte count 5,000/mm3
Platelet count 400,000/mm3
Serum
Urea nitrogen 28 mg/dL
Creatinine 1.2 mg/dL
Bilirubin
Total 7.0 mg/dL
Direct 5.5 mg/dL
Alkaline phosphatase 615 U/L
Aspartate aminotransferase (AST, GOT) 170 U/L
Alanine aminotransferase (ALT, GPT) 310 U/L
γ-Glutamyltransferase (GGT) 592 U/L (N = 5–50 U/L)
An ultrasound shows extrahepatic biliary dilation. A CT scan of the abdomen shows a 2.5-cm (1-in) mass in the head of the pancreas with no abdominal lymphadenopathy. The patient undergoes biliary stenting. Which of the following is the most appropriate next step in the management of this patient?
- A. Gemcitabine and 5-fluorouracil therapy
- B. Stereotactic radiation therapy
- C. Central pancreatectomy
- D. Gastroenterostomy
- E. Pancreaticoduodenectomy (Correct Answer)
Palliative surgical procedures Explanation: ***Pancreaticoduodenectomy***
- The patient presents with **obstructive jaundice**, a **pancreatic head mass** on CT, and **significant weight loss**, highly suggestive of **pancreatic adenocarcinoma**.
- Given the mass is localized to the head of the pancreas without evidence of metastases or lymphadenopathy on CT, **surgical resection (Whipple procedure)** is the only potentially curative treatment.
*Gemcitabine and 5-fluorouracil therapy*
- This is a form of **chemotherapy** commonly used for **advanced or metastatic pancreatic cancer**, or as adjuvant therapy after surgical resection.
- It is not the most appropriate *initial* step for a potentially resectable tumor, as surgery offers the best chance for cure.
*Stereotactic radiation therapy*
- **Radiation therapy** is typically used for **locally advanced, unresectable pancreatic cancer** to control tumor growth and symptoms, or as an adjunct to chemotherapy.
- It is not a primary curative treatment for resectable pancreatic head masses.
*Central pancreatectomy*
- **Central pancreatectomy** is a less common procedure typically reserved for tumors in the **neck or body of the pancreas**, aiming to preserve the pancreatic head and tail.
- It is not appropriate for a mass located in the **head of the pancreas** that is causing biliary obstruction.
*Gastroenterostomy*
- **Gastroenterostomy** is a **palliative surgical procedure** used to bypass an obstructed duodenum, often due to an **unresectable pancreatic head mass** causing gastric outlet obstruction.
- While the patient has obstructive jaundice, the primary goal here is to resect the tumor, not merely bypass the obstruction, especially since it appears resectable.
Palliative surgical procedures US Medical PG Question 9: A 63-year-old female with known breast cancer presents with progressive motor weakness in bilateral lower extremities and difficulty ambulating. Physical exam shows 4 of 5 motor strength in her legs and hyper-reflexia in her patellar tendons. Neurologic examination 2 weeks prior was normal. Imaging studies, including an MRI, show significant spinal cord compression by the metastatic lesion and complete erosion of the T12 vertebrae. She has no metastatic disease to the visceral organs and her oncologist reports her life expectancy to be greater than one year. What is the most appropriate treatment?
- A. Palliative pain management consultation
- B. Surgical decompression and postoperative radiotherapy (Correct Answer)
- C. High-dose corticosteroids and clinical observation
- D. Radiation therapy alone
- E. Chemotherapy alone
Palliative surgical procedures Explanation: ***Surgical decompression and postoperative radiotherapy***
- There is **spinal cord compression** by a metastatic lesion in a patient with a good prognosis (>1 year life expectancy) and rapidly progressive neurological deficits. **Surgical decompression** offers immediate relief of compression, while **postoperative radiotherapy** helps local tumor control.
- This combined approach is superior in preserving neurological function and improving quality of life for patients with **epidural spinal cord compression (ESCC)** in this clinical context.
*Palliative pain management consultation*
- While pain management is important in cancer care, this option alone does not address the **progressive neurological deficits** due to spinal cord compression.
- This patient's condition requires active treatment to prevent further neurological compromise and is not solely focused on comfort measures at this stage given her prognosis.
*Spinal dose corticosteroids and clinical observation*
- **Corticosteroids** can temporarily reduce edema around the spinal cord, but they do not resolve the mechanical compression caused by the eroded T12 vertebrae.
- **Clinical observation** without definitive intervention risks irreversible neurological damage given the rapid progression of symptoms.
*Radiation therapy alone*
- While radiation therapy is effective for local tumor control, it may not provide **rapid enough decompression** for acute or rapidly progressing neurological deficits due to significant mechanical compression.
- In cases of severe compression, such as bone erosion and cord involvement, surgery is usually needed prior to or in combination with radiation.
*Chemotherapy alone*
- **Chemotherapy** for breast cancer is a systemic treatment and may take time to reduce tumor burden, which is not suitable for urgent relief of **spinal cord compression**.
- It does not provide immediate mechanical decompression and is generally not the primary treatment for acute ESCC, especially with bone involvement.
Palliative surgical procedures US Medical PG Question 10: Fourteen days after a laparoscopic cholecystectomy for cholelithiasis, a 45-year-old woman comes to the emergency department because of persistent episodic epigastric pain for 3 days. The pain radiates to her back, occurs randomly throughout the day, and is associated with nausea and vomiting. Each episode lasts 30 minutes to one hour. Antacids do not improve her symptoms. She has hypertension and fibromyalgia. She has smoked 1–2 packs of cigarettes daily for the past 10 years and drinks 4 cans of beer every week. She takes lisinopril and pregabalin. She appears uncomfortable. Her temperature is 37°C (98.6° F), pulse is 84/min, respirations are 14/min, and blood pressure is 127/85 mm Hg. Abdominal examination shows tenderness to palpation in the upper quadrants without rebound or guarding. Bowel sounds are normal. The incisions are clean, dry, and intact. Serum studies show:
AST 80 U/L
ALT 95 U/L
Alkaline phosphatase 213 U/L
Bilirubin, total 1.3 mg/dL
Direct 0.7 mg/dL
Amylase 52 U/L
Abdominal ultrasonography shows dilation of the common bile duct and no gallstones. Which of the following is the most appropriate next step in management?
- A. Counseling on alcohol cessation
- B. Endoscopic retrograde cholangiopancreatography (Correct Answer)
- C. Proton pump inhibitor therapy
- D. CT scan of the abdomen
- E. Reassurance and follow-up in 4 weeks
Palliative surgical procedures Explanation: ***Endoscopic retrograde cholangiopancreatography***
- The patient's symptoms (epigastric pain radiating to the back, nausea, vomiting, elevated liver enzymes, and **common bile duct (CBD) dilation** on ultrasound after cholecystectomy) are highly suggestive of **postcholecystectomy syndrome**, specifically due to a retained or de novo **CBD stone** or **sphincter of Oddi dysfunction**.
- **ERCP** is both diagnostic and therapeutic in this setting, allowing for visualization of the bile ducts, stone extraction (if present), or sphincterotomy.
*Counseling on alcohol cessation*
- While **alcohol cessation** is beneficial for overall health, especially with a history of alcohol use, it is not the most immediate or appropriate next step for the acute and severe symptoms presented.
- The patient's symptoms are more indicative of a **biliary obstruction** rather than alcohol-related chronic pancreatitis or liver disease, given the acute onset post-surgery.
*Proton pump inhibitor therapy*
- **PPI therapy** is used for acid-related disorders such as GERD or peptic ulcers, which typically present with burning epigastric pain that improves with antacids.
- This patient's pain radiates to the back, is associated with nausea and vomiting, does not improve with antacids, and has abnormal imaging/labs (CBD dilation, elevated liver enzymes), ruling out a simple acid-related issue.
*CT scan of the abdomen*
- An abdominal **CT scan** could provide more detailed imaging but is generally less effective than ERCP for evaluating **biliary duct pathology** and is not therapeutic.
- Given the ultrasound findings of **CBD dilation** and the patient's symptoms, a more invasive but definitive diagnostic and therapeutic procedure is warranted.
*Reassurance and follow-up in 4 weeks*
- The patient is experiencing severe, persistent symptoms with abnormal liver enzymes and imaging findings indicating **biliary obstruction** post-cholecystectomy.
- **Reassurance and delayed follow-up** would be inappropriate and could lead to worsening of her condition, including cholangitis or pancreatitis if left untreated.
