Gastrointestinal Surgery Practice Questions

Q: Forrest classification is used for evaluating:

Upper GI bleeding. ***Upper GI bleeding*** - The **Forrest classification** is a widely used endoscopic classification system that assesses the status of bleeding from a peptic ulcer. - It helps predict the risk of **rebleeding** and guides treatment decisions, ranging from active bleeding requiring urgent intervention to signs of recent hemorrhage or no visible signs of bleeding. *Familial adenomatous polyposis* - This is a **hereditary syndrome** characterized by the development of hundreds to thousands of adenomatous polyps in the colon and rectum. - Its evaluation primarily involves **genetic testing**, colonoscopy surveillance, and screening for extracolonic manifestations. *Liver transplantation* - The evaluation for liver transplantation involves complex scoring systems like the **MELD (Model for End-Stage Liver Disease) score** or Child-Pugh score. - These scores assess the severity of liver disease and predict short-term mortality to prioritize patients for transplantation. *Lower GI bleeding* - Lower GI bleeding typically originates distal to the ligament of Treitz and is evaluated using different techniques like **colonoscopy**, angiography, or capsule endoscopy. - Specific classification systems for lower GI bleeding are not commonly referred to as the Forrest classification.

Q: In a female with appendicitis in pregnancy the treatment of choice is:

Surgery at earliest. ***Surgery at earliest*** - **Prompt surgical intervention** is crucial for appendicitis in pregnancy to prevent complications such as perforation, peritonitis, and maternal or fetal morbidity and mortality. - Delaying surgery increases the risk of rupture, which can be devastating for both the mother and the fetus. *Continue pregnancy with medical Rx* - **Medical management (antibiotics alone)** is generally ineffective for acute appendicitis in pregnant women and carries a high risk of progression to perforation. - This approach would expose the mother and fetus to serious complications, including sepsis and preterm labor, without addressing the underlying surgical pathology. *Surgery after delivery* - Delaying surgery until after delivery is unsafe and potentially fatal, as **appendiceal rupture could occur at any time** during pregnancy. - The risk of **perforation, peritonitis, and subsequent complications** is too high to justify waiting. *Abortion with appendectomy* - **Therapeutic abortion** is not indicated for uncomplicated appendicitis in pregnancy and does not improve the maternal prognosis for the appendicitis itself. - The focus is on treating the underlying medical condition (appendicitis) while preserving the pregnancy, if possible.

Q: Most common cause of esophageal perforation at the site of cricopharynx -

Iatrogenic. ***Iatrogenic*** - Most esophageal perforations, especially at the cricopharyngeal level, are **iatrogenic**, typically occurring during **endoscopic procedures** such as esophagogastroduodenoscopy (EGD), transesophageal echocardiography (TEE), or esophageal dilation. - The cricopharynx (or upper esophageal sphincter) is a narrow, relatively weak area of the esophagus, making it susceptible to injury during instrument passage. - Accounts for approximately **50-70%** of all esophageal perforations at this site. *Spontaneous* - Spontaneous esophageal perforation (Boerhaave syndrome) usually occurs in the **distal esophagus** following episodes of severe retching and vomiting. - It is far less common in the cervical esophagus or cricopharyngeal region compared to iatrogenic causes. *Foreign body* - Foreign body impaction can cause esophageal perforation, particularly at anatomical narrowing points. - However, at the cricopharynx level, **iatrogenic injury during endoscopic removal** of foreign bodies is more common than direct perforation from the foreign body itself. *Traumatic* - **External blunt or penetrating trauma** to the neck can cause esophageal perforation, but this is less common than iatrogenic causes at the cricopharynx. - While trauma can certainly cause perforation, instrument-related perforations during medical procedures are statistically more frequent in this area.

Q: Alvarado score is used for

Acute appendicitis. ***Acute appendicitis*** - The **Alvarado score**, also known as the MANTRELS score, is a clinical prediction rule used to assist in the diagnosis of **acute appendicitis**. - It assigns points based on symptoms (migratory pain, anorexia, nausea/vomiting), signs (tenderness in the right iliac fossa, rebound tenderness), and laboratory findings (elevated temperature, leukocytosis, left shift of neutrophils). *Acute epididymitis* - Diagnosis typically relies on clinical findings like **unilateral testicular pain and swelling**, often associated with dysuria or urethral discharge. - While it has scoring systems (like the Epididymitis Severity Score), the **Alvarado score** is not used for its diagnosis. *Acute pancreatitis* - Diagnosed based on characteristic **epigastric pain**, elevated serum amylase or lipase levels, and imaging findings. - Severity is often assessed using scoring systems like **Ranson's criteria** or APACHE II, not the Alvarado score. *Acute cholecystitis* - Diagnosed by symptoms such as **right upper quadrant pain**, fever, and leukocytosis, often with **positive Murphy's sign** and imaging evidence (e.g., gallbladder wall thickening on ultrasound). - The **Alvarado score** is not relevant to the diagnosis or severity assessment of acute cholecystitis.

Q: A 40 years old male was brought emergency with severe abdominal pain. On examination, pulse rate was 112/minute and systolic BP was 80 mmHg. Chest x-ray is given below. What is the most appropriate management?

Exploratory laparotomy. ***Exploratory laparotomy*** - The chest x-ray shows **pneumoperitoneum (air under the diaphragm)**, which, combined with severe abdominal pain, tachycardia, and hypotension (signs of **septic shock**), is highly indicative of a **perforated viscus**. - **Emergency exploratory laparotomy** is the definitive treatment to identify and repair the perforation, control contamination, and prevent further deterioration. *Saline wash of stomach* - This procedure is typically used for gastric lavage in cases of **poisoning or drug overdose**, or to clear the stomach in preparation for endoscopy. - It does not address a viscus perforation or the widespread abdominal contamination and systemic septic response seen in this patient. *Intercostal tube drainage* - **Intercostal tube drainage** (chest tube placement) is used to drain air (pneumothorax) or fluid (pleural effusion, hemothorax, empyema) from the pleural space, not the abdominal cavity. - While there is air visible on the x-ray, it is **subdiaphragmatic (pneumoperitoneum)**, not within the pleural space, and thus a chest tube would be ineffective and inappropriate. *IV antibiotics* - **Intravenous antibiotics** are crucial for managing sepsis associated with a perforated viscus and should be administered promptly. - However, antibiotics alone are **not sufficient** to treat the underlying mechanical problem of a perforation, which requires surgical repair to prevent ongoing bacterial contamination and sepsis.

Q: Cushing ulcers are:-

Stress ulcers in head injury. ***Stress ulcers in head injury*** - **Cushing ulcers** are acute **gastric or duodenal ulcers** that develop after a severe **head injury** or other central nervous system trauma. - The pathophysiology involves **vagal overstimulation** due to increased intracranial pressure, leading to hypersecretion of **gastric acid** and reduced mucosal blood flow. *Stress ulcers in hiatus hernia* - A **hiatus hernia** is a condition where part of the stomach protrudes through the diaphragm into the chest cavity, which can predispose to reflux and esophagitis. - While patients with hiatus hernia might develop ulcers, these are not specifically termed Cushing ulcers, and the primary cause is mechanical or reflux-related, not neurological. *Stress ulcers in burns* - **Stress ulcers** that occur in burn patients are known as **Curling ulcers**, not Cushing ulcers. - These are typically caused by **hypovolemia, vasoconstriction**, and **ischemia** of the gastrointestinal mucosa due to significant fluid loss and systemic inflammatory response. *Stress ulcers in depression* - **Depression** is a mood disorder that can influence gastrointestinal function through the **gut-brain axis**, potentially affecting motility and visceral hypersensitivity. - However, depression is not directly associated with the formation of acute stress ulcers like Cushing ulcers, which are primarily linked to severe CNS injury.

Q: A middle aged man complains of upper abdominal pain after a heavy meal. There is tenderness in the upper abdomen and on X-ray, widening of the mediastinum is seen with air in the mediastinum. What is the diagnosis?

Spontaneous perforation of the esophagus. ***Spontaneous perforation of the esophagus*** - The combination of **upper abdominal pain after a heavy meal** (suggestive of regurgitation/vomiting), **tenderness in the upper abdomen**, and **widening of the mediastinum with air in the mediastinum (pneumomediastinum)** points strongly to spontaneous esophageal rupture, also known as **Boerhaave syndrome**. - This condition results from a sudden increase in intra-esophageal pressure, often due to forceful vomiting, leading to a full-thickness tear in the esophageal wall. *Perforated peptic ulcer* - While it causes **severe upper abdominal pain** and tenderness, a perforated peptic ulcer primarily leads to **pneumoperitoneum** (free air under the diaphragm) rather than pneumomediastinum. - The abdominal symptoms would be more generalized and severe, and the X-ray findings would typically show free air in the abdominal cavity, not the mediastinum. *Rupture of emphysematous bulla* - This would generally cause **pneumothorax** and/or **subcutaneous emphysema**, and potentially pneumomediastinum, but typically without the profound abdominal pain and tenderness associated with a gastrointestinal event. - It would not be directly linked to a heavy meal or suggest a primary esophageal pathology. *Foreign body in esophagus* - A foreign body could cause pain and dysphagia, and potentially lead to perforation if sharp or impacted for too long, but the primary presentation would likely involve difficulty swallowing or a sensation of obstruction. - The immediate presence of **pneumomediastinum** and severe abdominal pain after a meal makes acute perforation more likely than a simple foreign body impaction without prior perforation.

Q: Most common site of chronic gastric ulcer:

Lesser curve near incisura. ***Lesser curve near incisura*** - The **lesser curve** of the stomach, particularly the **incisura angularis** or the angular notch, is the most common site for gastric ulcers. - This area is susceptible to ulceration due to its anatomical location, which experiences significant **acid exposure** and **motility stress**. *Lesser curve near proximal stomach* - While the lesser curve is a common site, ulcers tend to be more prevalent in the **distal part** of the lesser curve, near the incisura, rather than the proximal stomach (cardia or fundus). - Gastric ulcers in the proximal stomach are less frequent compared to the **antrum** and **incisura region**. *Pylorus of stomach* - The **pylorus** is more commonly associated with duodenal ulcers but can occasionally be a site for gastric ulcers. - However, it is not the most common location for **chronic gastric ulcers** when compared to the lesser curve near the incisura. *Greater curvature* - Ulcers on the **greater curvature** are relatively rare and often raise suspicion for **malignancy**, necessitating careful biopsy and investigation. - The greater curvature is less exposed to the erosive effects of gastric acid and pepsin compared to the lesser curve, making ulcers there less common.

Q: Which layer differentiates Boerhaave syndrome from Mallory-Weiss tear in terms of depth of involvement?

Adventitia. **Adventitia** - **Boerhaave syndrome** involves a **complete rupture** of the esophagus, extending through all layers, including the adventitia. - In contrast, a **Mallory-Weiss tear** is a **partial-thickness tear** that does not extend beyond the muscularis mucosae or submucosa and thus does not involve the adventitia. - The adventitia is the **key differentiating layer** - its involvement indicates full-thickness perforation (Boerhaave) versus partial-thickness tear (Mallory-Weiss). *Muscularis* - **Mallory-Weiss tears** can involve the **muscularis mucosae** or extend into the submucosa, but they do not typically penetrate the entire muscularis propria. - **Boerhaave syndrome** always involves the muscularis propria, as it is a full-thickness rupture. *Submucosa* - **Mallory-Weiss tears** can extend into the **submucosa**, which is the deepest layer they typically affect. - **Boerhaave syndrome** always involves the submucosa as part of its full-thickness esophageal perforation. *Mucosa* - Both **Boerhaave syndrome** and **Mallory-Weiss tears** involve the **mucosa** as it is the innermost layer of the esophagus. - However, the depth of involvement beyond the mucosa is what differentiates the two conditions.

Q: True about Mallory-Weiss tear is:

Occurs at GE junction. ***Occurs at GE junction*** - A **Mallory-Weiss tear** is a longitudinal mucosal laceration located in the **gastroesophageal junction** or upper stomach. - It is typically caused by a sudden increase in intra-abdominal pressure, such as from **retching** or **vomiting**. *Always needs surgery* - The vast majority of Mallory-Weiss tears **resolve spontaneously** and do not require surgical intervention. - Management usually involves supportive care and, if bleeding persists, endoscopic hemostasis. *Involves all layers* - Mallory-Weiss tears are **mucosal or submucosal lacerations** and do not typically penetrate through all layers of the esophageal or gastric wall. - Tears that extend through all layers are known as **Boerhaave syndrome**, which is a more severe condition and a medical emergency. *Common in elderly* - Mallory-Weiss tears can occur in any age group, but they are **more common in middle-aged adults**, often associated with conditions like alcoholism. - While not exclusive to younger populations, calling it "common in elderly" is not a primary characteristic.
