Corrosive stricture esophagus  mcqs

C

In corrosive injury of the esophagus, routine early emergency surgery is generally not indicated. The primary approach involves stabilization, assessing the extent of injury, and supportive care. Surgery is reserved for specific complications, such as perforation or severe necrosis.

Other than the need for emergency surgery for bleeding or perforation, elective oesophageal resection should be deferred for at least 3 months until the fibrotic phase has been established.

Oesophageal replacement is usually required for very long or multiple strictures. Resection can be difficult because of perioesophageal inflammation in these patients.

Regular endoscopic examinations are the best way to assess stricture development .

Significant stricture formation occurs in about 50% of patients with extensive mucosal damageo Corrosives can cause significant pharyngolaryngeal oedema

In unusual circumstances, e.g. with extensive necrosis after corrosive ingestion, emergency oesophagectomy may be necessary.

Questions on Esophagus 

Alkali and acidic injuries to the esophagus, both leading causes of corrosive stricture of the esophagus, differ in their effects due to distinct chemical reactions with tissue.

 Mechanism of Injury

  • Alkali Injuries: Ingested alkalis (e.g., drain cleaners) cause liquefactive necrosis, where tissue rapidly breaks down. This process allows alkalis to penetrate deep into the esophageal layers, often causing severe, widespread injury that extends to adjacent tissues. As a result, alkali injuries frequently lead to extensive scarring and stricture formation over time, significantly impacting the esophageal lumen.
  • Acidic Injuries: Acids like hydrochloric acid cause coagulative necrosis, resulting in protein denaturation and an eschar formation. This eschar limits acid penetration depth, typically causing more superficial injury compared to alkalis. However, mucosal damage can still be severe, leading to ulceration and potential esophageal stricture over time, especially if the injury affects the lower esophagus.

Pseudoachalasia

Q) Most common cause of  pseudoachalasia is ?

(a) Benign tumors of esophagus

(b) Chagas disease

(c) Caustic injury

(d) Adenocarcinoma of cardia


d

Pseudoachalasia is an achalasia-like disorder that is usually produced by adenocarcinoma of the cardia

Other uncommon causes are

 1.benign tumours at this level.

2, Tumors of bronchus, pancreas

It  is a condition that mimics the symptoms of achalasia, but is caused by a different underlying problem. The most common cause  is  malignancy in the gastroesophageal junction (GEJ), which is the area where the esophagus meets the stomach. Other possible causes of pseudoachalasia include:

  • Esophageal stricture
  • Chagas disease
  • Radiation therapy to the chest
  • Aortic aneurysm
  • Thyroid cancer

Pseudoachalasia presents in an identical manner to idiopathic achalasia with progressive dysphagia to solids and liquids, retrosternal pain, regurgitation of undigested foods and weight loss.

The main difference between pseudoachalasia and achalasia is that it  is often associated with other symptoms, such as abdominal pain, vomiting, and weight loss.

The diagnosis is made through a combination of clinical evaluation, upper endoscopy, and esophageal manometry. Upper endoscopy can help to rule out a malignancy in the GEJ, and esophageal manometry can help to confirm the diagnosis of achalasia. In some cases, a CT scan or MRI of the chest may be needed to further evaluate the cause of pseudoachalasia.

Squamous cell cancer of upper esophagus

Q) A 65-year-old male presents with grade IV dysphagia and is diagnosed with squamous cell carcinoma of the upper third of the esophagus. What is the most appropriate next step in management?

a) Definitive chemoradiotherapy
b) Neoadjuvant chemotherapy followed by transhiatal esophagectomy
c) Systemic chemotherapy alone
d) Neoadjuvant chemoradiotherapy followed by three-field esophagectomy

✅ Correct answer: a) Definitive chemoradiotherapy

💡 Explanation:

  • Upper third esophageal squamous cell carcinoma poses a challenge for surgical resection due to its proximity to the pharynx and larynx.

  • In resectable upper esophageal SCC, especially in older patients or when the tumor is very proximal, definitive chemoradiotherapy (CRT) is often the preferred treatment to avoid morbid surgery like laryngopharyngoesophagectomy.

  • Multiple guidelines, including NCCN and ESMO, recommend definitive CRT for upper esophageal SCC unless there’s a compelling reason for surgery.


❌ Why other options are incorrect:

  • b) Neoadjuvant chemo + THE:
      THE (transhiatal esophagectomy) is not suitable for upper esophageal tumors. It doesn't provide good access to cervical/upper thoracic esophagus.

  • c) Chemotherapy alone:
      Not standard. Chemotherapy without radiation is inadequate for curative intent in localized esophageal cancer.

  • d) Neoadjuvant CRT + three-field esophagectomy:
      Though this is an option for mid/lower third esophageal cancers, especially in younger patients, it's more morbid and rarely used for upper third SCC in older patients.

Gastric pullup

Gastric Pull-Up Mobilization MCQ | Esophageal Surgery

Gastric Pull-Up Mobilization MCQ – Esophageal Reconstruction

📘 Theme: Esophageal Surgery – Gastric Conduit Mobilization (NEET SS / INI-CET High Yield)

Gastric Pull-Up Surgical Technique MCQ

Which of the following is NOT a routine step in gastric pull-up mobilization during esophageal reconstruction?

A. Entering the lesser sac
B. Posterior mobilization of the duodenum
C. Dilatation of the esophageal hiatus
D. Ligation of the lesser curvature vessels

Answer: B. Posterior mobilization of the duodenum

Explanation

Gastric pull-up involves mobilization of the stomach to create a well-vascularized conduit for esophageal replacement. Important steps include entering the lesser sac, dividing relevant gastric attachments and vessels while preserving the right gastroepiploic vascular arcade, and enlarging the esophageal hiatus when necessary to facilitate passage of the conduit.

Posterior mobilization of the duodenum, performed by the Kocher manoeuvre, is not a routine essential step in standard gastric conduit mobilization. It may be performed selectively when additional duodenal mobilization is required.

Why other options are incorrect

  • A. Entering the lesser sac: Helps mobilize the greater curvature and provides access to the posterior surface of the stomach.
  • C. Dilatation of the esophageal hiatus: The hiatus may need enlargement to allow safe passage of the gastric conduit into the chest without compression.
  • D. Ligation of the lesser curvature vessels: Division of the left gastric vessels and relevant lesser-curvature attachments facilitates mobilization while preserving the right gastroepiploic artery as the principal blood supply to a standard gastric conduit.

High-yield teaching points

  • The right gastroepiploic artery is the principal vascular supply of a standard gastric conduit.
  • The left gastric vessels are divided during routine conduit preparation.
  • The Kocher manoeuvre mobilizes the duodenum and is performed selectively, rather than routinely, during gastric pull-up.
  • Avoid twisting, tension, or compression of the conduit during its passage through the hiatus.

Answer 

In  caustic injuries to the esophagus, early decisions have to be taken. The involvement of surgeon should be done early and patient should be placed under close monitoring.

Blind nasogastric and orogastric tubes should not be inserted and initially CT of chest and abdomen with contrast should be done to guide the subsequent procedures. Read on
