Welcome to our podcast on endoscopic resection of Zenker's diverticulum. Today, we'll dive deep into this condition, its treatment, and the benefits of endoscopic approaches.
Zenker's diverticulum is a rare disorder of the esophagus, primarily affecting elderly individuals between their 70s and 90s. It's more common in men and occurs in about 0.01% to 0.11% of the population, with higher rates in northern Europe, the United States, and Canada[1].
This condition involves a pouch forming in the hypopharynx, typically between the cricopharyngeus (CP) muscle and the inferior pharyngeal constrictor muscle. It's a false diverticulum, meaning it only involves the mucosa and submucosal layers, not the muscular layer[1].
The exact cause isn't fully understood, but it's believed to result from abnormal pressure during swallowing, causing a weakness in the Killian triangle - the area between the horizontal and oblique fibers of the cricopharyngeus muscle[1].
Patients typically present with a long history of dysphagia, or difficulty swallowing, which occurs in up to 98% of cases. Other common symptoms include regurgitation, halitosis, aspiration, and recurrent coughing[1].
Traditionally, Zenker's diverticulum was treated with open surgery or rigid endoscopic techniques using a laryngoscope. However, these methods require general anesthesia, tracheal intubation, and are more invasive, leading to higher complication rates and longer hospital stays[2].
In recent years, flexible endoscopic treatment has emerged as a superior option. This approach offers several advantages:
1. It's less invasive, reducing patient discomfort.
2. It requires a shorter hospital stay, typically around 2 days.
3. Patients can resume oral food intake the day after treatment.
4. It has lower complication and mortality rates compared to traditional methods[2].
Now, let's discuss the key steps for performing an endoscopic resection:
1. Use of a transparent cap: This is attached to the endoscope tip. It stabilizes the view, maintains a safe distance from the tissue, and allows for precise incisions.
2. Ensuring clear visualization: The esophageal lumen and diverticulum should be clearly visible. If visibility is difficult, a guidewire or thin tube can be placed into the stomach to maintain a clear view of the esophagus.
3. Choosing the right tools: Various devices have been examined for this procedure. A hook knife is often preferred as it allows for controlled cutting and dissection of muscle fibers. Other options include argon plasma coagulation, different types of needles, stapling devices, and endoscopic scissors[3].
4. Performing the septotomy: This is done in stages. First, incise the mucosa, then the submucosa, and finally the muscle fibers. It's crucial to proceed slowly and steadily. The goal is to cut the cricopharyngeal muscle, which is the main objective of the treatment.
5. Safety closure: After dissecting to the base of the septum, place a closing clip at the apex of the dissection. This is the most vulnerable area for perforation. A clip with a short stem is preferred to avoid irritating the opposite wall.
It's important to note that this procedure is challenging and should be performed by endoscopists with high expertise in therapeutic endoscopy. It requires special training, which can be difficult to obtain due to the rarity of the condition[2].
The benefits of endoscopic treatment are significant. Patient satisfaction is reportedly very high, with patients appreciating the non-invasive nature, short hospital stay, and high rates of dysphagia resolution. Even in cases of symptom recurrence, the procedure can usually be repeated effectively[2].
In conclusion, endoscopic resection of Zenker's diverticulum represents a

In this in-depth episode, we dive headfirst into one of the most polarizing topics in modern gastrointestinal medicine - the heated debate between cold snare polypectomy (CSP) and hot snare polypectomy (HSP) techniques.
Our host provides a comprehensive overview of these two pivotal polyp removal methods, exploring their pros, cons, and appropriate use cases. We learn about:
• The fundamentals of CSP and HSP
• European guideline recommendations for each technique based on polyp size
• Comparative data on complete resection rates and complication profiles
• Managing challenges like bleeding and tissue injury
• The critical importance of polyp retrieval and histopathological analysis
• Potential future advancements in endoscopic tools and techniques
• Adhering to best practices and clinical guidelines
Key Takeaways:
- CSP shows a superior safety profile for diminutive (<5mm) and small (6-9mm) sessile polyps
- HSP provides coagulation benefits for larger polyps (10-20mm) and bleeding control
- Both methods demonstrate comparable resection completeness for 4-10mm polyps
- HSP carries higher risks like delayed bleeding and deep thermal injury
- Polyp retrieval quality is high with both techniques for accurate diagnosis
- Technique choice depends on balancing polyp factors and patient needs
- Ongoing research and new technologies will further refine polypectomy
Whether you're a seasoned endoscopist or just getting started, this episode provides invaluable insights into optimizing polypectomy outcomes through the judicious application of CSP and HSP. Join us as we unpack this critical clinical debate.

The Couinaud classification is a vital tool in the field of hepatic surgery and diagnoses. It offers a comprehensive understanding of the functional anatomy of the liver by dividing it into eight independent segments. Unlike other classification systems, Couinaud classification focuses on the liver's functional aspects rather than its external appearance.
Key Takeaways:
Couinaud's innovative approach to liver segmentation has become a cornerstone in modern hepatic surgery, guiding surgeons in planning and executing procedures with utmost accuracy. By preserving the functional integrity of individual liver segments, surgical resection can be performed with optimal outcomes, enhancing patient recovery and long-term prognosis.

In this episode of the Gastroenterology and Endoscopy podcast, we explore the importance of understanding and mastering different types of polypectomy snares in the endoscopic field. Not all lesions are the same, and using just one type of snare for all scenarios is often ineffective. We discuss the advantages of snares with expansial memory and hexagonal or oval snares with double buckles. The range of polypectomy snares available is vast, and each endoscopist will discover the snare that best suits their needs through practice and personal preference. Factors to consider when selecting a snare include the lesion's size and shape, the snare's ability to retain its shape and durability, and personal comfort and proficiency. Understanding and experimenting with various polypectomy snares enhances the ability to adapt to different clinical situations and leads to improved patient care.
Understanding Polypectomy Snares: A Guide for Endoscopists
Polypectomy snares are critical tools in the armamentarium of an endoscopist, and it’s essential to become adept with at least two types due to the variability in lesion sizes and shapes. A single snare type cannot accommodate all scenarios. Here’s a closer look at the diversity of snares and their functionalities:
However, it’s crucial to remember — there’s a plethora of tools available. Each endoscopist will, through experience and preference, determine which snare aligns best with their practice. Let’s delve into some of the key factors to consider:
In summary, while the variety of polypectomy snares may seem daunting, understanding their unique features and testing different types can greatly enhance an endoscopist’s proficiency and adaptability in managing diverse lesions.

In this episode of the Gastroenterology and Endoscopy Podcast, we explore the world of water-assisted colonoscopy (WAC). WAC is a technique that uses water instead of air or gas during the insertion phase of a colonoscopy, offering numerous benefits for both endoscopists and patients. By utilizing water's natural properties, WAC can reduce pain and discomfort, straighten out the colon, and enhance visibility of the mucosal surface. This technique not only improves patient comfort but also plays a crucial role in colorectal cancer prevention by improving adenoma detection rates. Join us as we delve into the advantages of WAC over traditional methods and its potential impact in the field of gastroenterology.

In this episode of the Gastroenterology and Endoscopy podcast, we discuss a challenging case involving a pedunculated duodenal adenoma. These types of polyps present unique challenges for endoscopists, requiring meticulous planning for a successful procedure. The goal is to achieve a complete R0 resection, removing the entire lesion without leaving any microscopic remnants. We explore strategies to prevent migration of the polyp into the bowel, such as positioning the patient in a decubitus supine position or using an antimotility agent. The endoscopist and assistant must be on high alert to catch the polyp with the snare, and having a Roth's net on standby is recommended.

In this episode, we discuss the importance of improving colonoscopy prep and achieving better Boston bowel preparation scores. Colon cancer is the second leading cause of cancer death in the US, but it is preventable through colonoscopies. However, the success of a colonoscopy relies heavily on proper bowel preparation. Inadequate prep can decrease polyp detection rates by 27%. Patients are advised to follow a special diet and take a bowel cleansing solution prior to the procedure to ensure a clear view of the colon. The cleanliness of the colon is graded using the Boston Bowel Preparation Scale, with a minimum score of 6 recommended for optimal polyp detection. Unfortunately, the endoscopy center discussed in the episode noticed alarmingly low Boston prep scores among their patients.
