Laparoscopic Appendectomy Indian Medical PG Practice Questions and MCQs
Question 1: Which of the following is NOT a CONTRAINDICATION for laparoscopic surgery:
- A. Severe COPD
- B. Bowel herniation
- C. Endometriosis (Correct Answer)
- D. Severe cardiac compromise
Explanation: ***Endometriosis*** - **Endometriosis** is a *common indication* for laparoscopic surgery, as laparoscopy allows for both diagnosis and treatment (e.g., excision or ablation of endometrial implants). - It is *not* a contraindication; in fact, laparoscopy is the **gold standard** for diagnosing and managing endometriosis due to its minimally invasive nature and excellent visualization. *Severe COPD* - **Severe COPD** is a significant *contraindication* because pneumoperitoneum increases intra-thoracic pressure and elevates the diaphragm, reducing functional residual capacity. - This can cause *hypercarbia*, *hypoxemia*, and respiratory compromise in patients with already limited pulmonary reserve, making general anesthesia and laparoscopy high-risk. *Bowel herniation* - **Incarcerated or strangulated bowel herniation** is generally a *relative contraindication* due to the risk of intestinal injury during trocar insertion or manipulation. - The presence of *adhesions* and compromised bowel can make laparoscopic access challenging, though experienced surgeons may still attempt laparoscopic repair in selected cases. *Severe cardiac compromise* - **Severe cardiac compromise** is a significant *contraindication* because pneumoperitoneum causes increased intra-thoracic pressure, reduced venous return, and increased systemic vascular resistance. - This can lead to decreased *cardiac output*, arrhythmias, and hemodynamic instability, posing substantial risk to patients with severe cardiovascular disease.
Question 2: Under what guidelines is treatment started for a patient presenting with appendicular mass on a CT scan?
- A. Ochsner Sherren Regimen (Correct Answer)
- B. Conservative management and discharge
- C. Kocher's Regimen
- D. Immediate Laparotomy
Explanation: ***Ochsner Sherren Regimen*** - The **Ochsner Sherren regimen** is a conservative management approach specifically used for patients presenting with an **appendicular mass** (a palpable mass formed by the inflamed appendix, omentum, and small bowel loops). - This regimen involves **nil by mouth**, **intravenous fluids**, **antibiotics**, and **analgesia**, with close observation to allow the inflammation to subside before potential interval appendectomy. *Conservative management and discharge* - While the Ochsner Sherren regimen is a form of conservative management, simply stating "conservative management and discharge" is incomplete and potentially dangerous for a patient with an **appendicular mass**. - **Discharge** is not appropriate without a period of observation and specific medical interventions like antibiotics, as there's a risk of abscess formation or perforation. *Kocher's Regimen* - **Kocher's regimen** is not a recognized treatment protocol for an appendicular mass. - The term "Kocher" is more commonly associated with a **surgical incision** (Kocher incision for cholecystectomy) or a **maneuver** (Kocher maneuver for duodenal mobilization). *Immediate Laparotomy* - **Immediate laparotomy** is generally contraindicated in the presence of a well-formed **appendicular mass**. - Operating on a friable, inflamed mass can disrupt the natural containment, leading to widespread peritonitis and increased morbidity. The Ochsner Sherren regimen aims to cool down the inflammation first.
Question 3: Which of the following is NOT a contraindication for laparoscopic cholecystectomy?
- A. Patients with severe liver cirrhosis and portal hypertension
- B. Patients with obesity (Correct Answer)
- C. Patients with a history of previous abdominal surgery
- D. Patients with severe chronic obstructive pulmonary disease (COPD)
Explanation: ***Patients with obesity*** - **Obesity** is not a contraindication for laparoscopic cholecystectomy and is actually often considered a **relative indication** for the laparoscopic approach over open surgery. - Laparoscopic cholecystectomy in obese patients offers significant advantages including reduced wound complications, decreased infection rates, better cosmesis, and faster recovery. - While technically more challenging due to thicker abdominal wall and increased intra-abdominal fat, experienced surgical teams routinely perform laparoscopic cholecystectomy in obese patients safely. *Patients with severe liver cirrhosis and portal hypertension* - **Severe liver cirrhosis and portal hypertension** are considered absolute or strong contraindications due to significantly increased risk of bleeding from dilated collateral vessels and impaired coagulation. - Pneumoperitoneum can further compromise hepatic blood flow and worsen portal hypertension. - These patients often require open surgery with careful hemostasis or medical management due to prohibitively high operative risk. *Patients with severe chronic obstructive pulmonary disease (COPD)* - Patients with **severe COPD** with poor pulmonary reserve may have difficulty tolerating pneumoperitoneum due to increased intrathoracic pressure, reduced diaphragmatic excursion, and decreased ventilation-perfusion matching. - Hypercarbia from CO₂ absorption and increased airway pressures can lead to significant respiratory compromise in patients with limited pulmonary reserve. - While mild-moderate COPD is not a contraindication with appropriate anesthetic management, severe COPD with inability to tolerate pneumoperitoneum constitutes a contraindication. *Patients with a history of previous abdominal surgery* - A history of **previous abdominal surgery** is considered at most a **relative contraindication**, not an absolute one, and is routinely managed in modern laparoscopic practice. - While intra-abdominal adhesions may increase technical difficulty and risk of bowel injury, techniques like open Hassan port insertion and careful adhesiolysis allow safe laparoscopic surgery in most cases. - Previous surgery requires careful preoperative assessment and may necessitate modified port placement or conversion to open if dense adhesions are encountered, but does not preclude attempting laparoscopy.
Question 4: What is the primary aim of performing an abbreviated laparotomy in trauma surgery?
- A. Definitive repair of all injuries
- B. Reduction of contamination
- C. Rapid stabilization of the patient
- D. Haemostasis (Correct Answer)
Explanation: ***Haemostasis*** - The primary aim of abbreviated laparotomy (damage control surgery) is to achieve **rapid control of life-threatening hemorrhage**. - This involves temporary measures to stop bleeding from major vessels and solid organ injuries, preventing exsanguination and further physiological deterioration. - **Damage control prioritizes hemorrhage control over definitive repair**, using techniques like packing, shunts, and temporary vessel ligation. *Definitive repair of all injuries* - This is specifically **NOT** the goal of abbreviated laparotomy. - Definitive repairs are **delayed** until the patient is physiologically stable (after resuscitation in ICU). - Attempting complete repair in an unstable patient leads to the "lethal triad" (hypothermia, acidosis, coagulopathy). *Reduction of contamination* - While contamination control is an **important component** of damage control surgery, it is typically **secondary to hemorrhage control**. - The sequence prioritizes stopping bleeding first, then controlling contamination from bowel injuries. *Rapid stabilization of the patient* - This is the **overall goal** of damage control surgery but not the specific primary aim of the laparotomy itself. - Stabilization is achieved **through** specific interventions during the abbreviated laparotomy, primarily haemostasis and contamination control.
Question 5: A 25 year old male is receiving conservative management for an appendicular mass since 3 days now presents with a rising pulse rate, tachycardia and fever. The mode of management must be -
- A. Proceed to laparotomy and appendicectomy (Correct Answer)
- B. Intravenous antibiotics
- C. Continue Ochsner Sherren regimen with close monitoring
- D. Continue conservative management
Explanation: ***Proceed to laparotomy and appendicectomy*** - A **rising pulse rate, tachycardia, and fever** indicate **worsening sepsis** or **perforation** of the appendicular mass, necessitating urgent surgical intervention. - Continuing conservative management in the face of these signs carries a high risk of **morbidity and mortality** from peritonitis or widespread sepsis. *Continue Ochsner Sherren regimen with close monitoring* - The Ochsner Sherren regimen is a **conservative approach** for a stable appendicular mass, which is no longer the case with signs of deterioration. - **Clinical worsening** (tachycardia, rising fever, increased pulse) signifies failure of conservative management and requires a shift to surgical intervention. *Continue conservative management* - Continuing conservative management despite **signs of deterioration** (rising pulse, tachycardia, fever) would lead to further progression of the disease and potential life-threatening complications. - These symptoms suggest that the infection is **not contained** and is likely spreading, indicating the need for immediate surgical treatment. *Intravenous antibiotics* - While intravenous antibiotics are part of the initial conservative management, they are **insufficient** alone for an appendicular mass showing signs of deterioration. - The worsening clinical picture suggests a **failed antibiotic response** or a more severe underlying issue (e.g., abscess rupture) that requires surgical drainage or removal.
Question 6: What is the appropriate management for a patient with a carcinoid tumor of the appendix larger than 2 cm?
- A. Right hemicolectomy (Correct Answer)
- B. Appendicectomy
- C. Appendicectomy + abdominal CT scan
- D. Appendicectomy + 24 hrs urinary HIAA
Explanation: ***Right hemicolectomy*** - Carcinoid tumors of the appendix larger than **2 cm** are considered at high risk for **lymph node metastasis** and recurrence. - A **right hemicolectomy** provides adequate margins and allows for lymph node dissection, which is essential for staging and definitive treatment in such cases. *Appendicectomy* - An **appendicectomy** alone is typically sufficient for carcinoid tumors of the appendix that are **less than 1 cm** and localized to the tip. - For larger tumors, appendicectomy carries an unacceptably high risk of **incomplete resection** and metastatic disease. *Appendicectomy + abdominal CT scan* - While an **abdominal CT scan** is useful for assessing local spread and distant metastases, it does not address the need for a more extensive surgical resection for a **large primary tumor**. - A simple **appendicectomy** in this scenario would be inadequate as definitive treatment. *Appendicectomy + 24 hrs urinary HIAA* - **24-hour urinary 5-hydroxyindoleacetic acid (5-HIAA)** is a biomarker used to detect and monitor **carcinoid syndrome**, which occurs in a minority of patients with carcinoid tumors. - Measuring 5-HIAA is primarily for assessing systemic symptoms rather than determining the primary surgical management of the **tumor size**.
Question 7: In which of the following conditions is Alvarado score indicated?
- A. Pancreatitis
- B. Appendicitis (Correct Answer)
- C. Cholangitis
- D. Cholecystitis
Explanation: ***Appendicitis*** - The Alvarado score, also known as the MANTRELS score, is a clinical scoring system used to assess the likelihood of **acute appendicitis**. - It considers symptoms (e.g., **migratory right iliac fossa pain**, **anorexia**, **nausea/vomiting**), signs (e.g., **tenderness in the right iliac fossa**, **rebound tenderness**), and laboratory findings (e.g., **leukocytosis**, **shift to the left of neutrophils**). *Pancreatitis* - Pancreatitis is typically diagnosed and managed using criteria such as the **Ranson criteria** or **APACHE II score** for severity assessment, and imaging like CT scans. - The Alvarado score is not applicable for the diagnosis or severity assessment of pancreatitis. *Cholangitis* - Cholangitis is an infection of the bile ducts which is usually diagnosed clinically using the **Charcot's triad** (fever, jaundice, right upper quadrant pain) or **Reynold's pentad** (Charcot's triad plus altered mental status and hypotension). - The Alvarado score has no role in the evaluation of cholangitis. *Cholecystitis* - Cholecystitis, inflammation of the gallbladder, is primarily diagnosed based on clinical symptoms (e.g., **right upper quadrant pain**, **fever**, **leukocytosis**), Murphy's sign, and imaging (ultrasound). - The Alvarado score is specifically designed for appendicitis and is not used for cholecystitis.
Question 8: A patient scheduled for elective inguinal hernia surgery has a history of myocardial infarction (MI) and underwent coronary artery bypass grafting (CABG). What should be included in the preoperative assessment?
- A. History + c/e + routine labs + V/Q scan
- B. History + c/e + routine labs
- C. History + c/e + routine labs + stress test (Correct Answer)
- D. History + c/e + routine labs + angiography to assess graft patency
Explanation: ***History + c/e + routine labs + stress test*** - A **stress test** is crucial in patients with a history of MI and CABG to assess **myocardial ischemia** and functional capacity, guiding perioperative management. - This evaluation helps determine the patient's **cardiac risk** for non-cardiac surgery and the need for further cardiac optimization. *History + c/e + routine labs + angiography to assess graft patency* - **Coronary angiography** is an invasive procedure and is generally not indicated as a routine preoperative assessment unless there are new, significant cardiac symptoms or signs of **graft dysfunction**. - Assessing graft patency through angiography carries risks and would only be justified if there were strong clinical indications suggesting acute or severe **cardiac ischemia**. *History + c/e + routine labs* - While critical for any preoperative assessment, **routine history, physical examination, and basic laboratory tests** are insufficient for a patient with a significant cardiac history like MI and CABG. - This approach would **underestimate the cardiac risk** and might miss undetected ischemia, leading to adverse perioperative cardiac events. *History + c/e + routine labs + V/Q scan* - A **ventilation-perfusion (V/Q) scan** is primarily used to diagnose **pulmonary embolism** or assess regional lung function. - It does not provide information about myocardial ischemia or cardiac functional capacity, making it **irrelevant** for assessing cardiac risk in this clinical scenario.
Question 9: Which of the following is not useful in the management of acute appendicitis?
- A. Analgesics
- B. IV fluids
- C. Antibiotics
- D. Purgation (Correct Answer)
Explanation: ***Purgation*** - **Purgation** (inducing vigorous bowel evacuation) is contraindicated in acute appendicitis as it can increase intraluminal pressure and potentially lead to **perforation** of the inflamed appendix. - Such aggressive bowel stimulation is harmful and offers no therapeutic benefit in managing appendicitis. *Antibiotics* - **Preoperative antibiotics** are crucial in acute appendicitis to cover potential bacterial contamination, especially in cases of suspected **perforation** or **gangrene**. - They help reduce the risk of **postoperative infections** and improve overall outcomes. *Analgesics* - **Analgesics** (pain relievers) are essential for managing the severe abdominal pain associated with acute appendicitis. - While traditionally withheld to avoid masking symptoms, it is now widely accepted that **adequate pain control** does not hinder diagnosis and improves patient comfort. *IV fluids* - Patients with acute appendicitis are often **dehydrated** due to anorexia, vomiting, and fever. - **Intravenous fluids** are critical to correct fluid and electrolyte imbalances, ensuring patient stability before and during surgery.
Question 10: The Chief of laparoscopic surgery asked his assistant to give him a laparoscopic port which has absolutely no chance of "capacitance coupling" during laparoscopic surgery. Which port should the assistant give to the Chief?
- A. Metal port with plastic cuff
- B. Complete plastic port (Correct Answer)
- C. Metal laparoscopic port
- D. Partial plastic port
Explanation: **Complete plastic port** - A **complete plastic port** is an **electrical insulator** and thus completely prevents the phenomenon of **capacitance coupling** during laparoscopic surgery. - This is the safest option when electrosurgery is used, as it eliminates the risk of inadvertent energy transfer to surrounding tissues through the trocar. *Metal port with plastic cuff* - While a plastic cuff might offer some insulation, the presence of a **metal outer cannula** still allows for the possibility of charge accumulation and subsequent **capacitance coupling**. - The plastic cuff alone is insufficient to prevent the capacitance effect from the metal shaft, as the internal metal may still induce a charge on nearby conductive objects. *Metal laparoscopic port* - A **metal laparoscopic port** is a **conductor** and is highly susceptible to **capacitance coupling**, transferring stray electrical currents to unintended tissues. - The direct contact of conductive metal with the abdominal wall can create a pathway for current leakage, increasing the risk of **thermal injury**. *Partial plastic port* - Similar to a metal port with a plastic cuff, a **partial plastic port** would still have exposed metal components that can accumulate charge and lead to **capacitance coupling**. - Any exposed metal section can act as an electrode, enabling the unintentional delivery of electrical energy to non-target tissues.
