What is Zenker's Diverticulum?

Zenker's diverticulum is a pseudodiverticulum formed by posterior herniation of pharyngeal mucosa through Killian's triangle, the weak area between the thyropharyngeus and inferior pharyngeal constrictor muscles.

It is most often seen in men over 60 years of age and is driven by cricopharyngeal muscle dysfunction with inadequate relaxation. Food retained inside the pouch produces halitosis and predisposes to aspiration.

Treatment is surgical, either by an endoscopic approach or by an open cervical procedure that combines cricopharyngeal myotomy with diverticulectomy or diverticulopexy.

Symptoms

Dysphagia for solids and liquids

Regurgitation of undigested food

Halitosis

Gurgling sounds in the neck

Chronic cough and aspiration

Unintentional weight loss

Risk Factors

Advanced age (over 60 years)

Male sex

Cricopharyngeal muscle spasm

Gastro-oesophageal reflux

Cervical osteophytes

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

Worsening difficulty in swallowing
Regurgitation of undigested food
Episodes of aspiration pneumonia
Associated unintentional weight loss

Treatment Methods

Endoscopic diverticulotomy (Dohlman procedure)

Trans-oral stapler-assisted diverticulostomy

Open cervical diverticulectomy with cricopharyngeal myotomy

Diverticulopexy in elderly patients

Cricopharyngeal myotomy

Swallowing rehabilitation

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
