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 episode we discuss using natural color changes called "biologic chromoendoscopy" to detect challenging flat colorectal lesions.
Key Topics Discussed: - While sessile and pedunculated polyps are easy to spot endoscopically, flat and serrated lesions are challenging - AI, virtual chromoendoscopy, and dyes aren't reliable for flat lesions obscured by mucus/debris - Mucus changes light penetration, traps stool, and creates a hazy appearance - Two mucin secretion changes: lost O-acetyl groups and increased sialylation - "Chicken skin mucosa" refers to white spots from lipid-laden macrophages linked to adenomas, cancer, and juvenile polyps - Melanosis coli is dark pigmentation from lipofuscin deposits due to chronic laxative use - Recognizing subtle color changes is critical for finding precancerous flat lesions - Human eye notices what AI systems miss when looking for discolored tissue
Key Quotes: - "I call the lesions' natural color changes 'biologic chromoendoscopy.'" - "Other examples are 'chicken skin mucosa' and melanosis coli." - "Recognizing these subtle color changes is critical for finding precancerous flat lesions."
References Made: - Mucin secretion changes in serrated lesions - Melanosis coli and anthraquinone laxative use - Chicken skin mucosa first described in Japan
ESD + EMR: How a Hybrid Technique Advances Endoscopic Resection
10 Oct 2023
00:04:29
Episode Overview: In this episode, host Dr. Alan Smith discusses a new hybrid endoscopic technique that combines aspects of ESD and EMR to improve resection of difficult to remove gastrointestinal lesions.
Key Topics Covered: - Limitations of traditional endoscopic resection techniques like ESD and EMR - Overview of the ESD-EMR hybrid technique (also called pre-cutting EMR) - Step-by-step explanation of how the hybrid technique works - Types of challenging GI lesions the hybrid technique is useful for - Benefits of the ESD-EMR approach over standard resection methods - Limitations and alternatives to the hybrid technique
Episode Highlights: - Laterally spreading colorectal lesions often cannot be fully resected with standard EMR snares due to slippery mucosa, leading to recurrence. The ESD-EMR hybrid technique creates a pre-cut groove around the lesion that enables complete en bloc snare resection. - Serrated polyps in the colorectum frequently evade polypectomy snares because of their subtle mucosal surfaces. The hybrid technique overcomes this with circumferential pre-cutting to allow complete snare capture. - For difficult to resect subepithelial tumors like lipomas, the combined ESD-EMR approach facilitates resection of larger lesions compared to standard EMR. - The hybrid technique decreases recurrence rates and lowers perforation risks versus ESD in less experienced hands.
Notable Quotes: "But ESD and EMR have limitations resecting certain flat, slippery lesions. Laterally spreading colorectal polyps often slip out of EMR snares, causing incomplete removal and recurrence."
"Making a customized groove around the lesion enables complete snare capture and resection of even challenging flat lesions."
"While limitations exist, this innovative ESD-EMR hybrid strategy expands the range of lesions treatable by endoscopic resection while minimizing recurrence and perforation risks."
Mastering Hemoclips: Techniques, Applications, and Improved Patient Outcomes
03 Oct 2023
00:04:11
In the latest episode of the Gastroenterology & Endoscopy Podcast we explore the innovative realm of Hemoclips, or Through-The-Scope-Clips, and their pivotal role in enhancing endoscopic procedures. Initially designed for hemostasis, these multifaceted tools have now widened their scope, proving to be indispensable in a variety of clinical scenarios.
Hemoclips Hemoclips, now often referred to as "clips", have seen their application extend beyond their original purpose of hemostasis. They are now employed for a range of uses including closing perforations, post-resection defects, marking, and attaching devices like stents and feeding tubes. For instance, during procedures involving gastric, esophageal, or colon perforation, clips can effectively seal the defect, averting further complications. This adaptation of clips over time truly signifies a leap in medical innovation.
Understanding the Anatomy and Deployment of Clips: Grasping the anatomy and the mechanisms governing the deployment of clips is essential for their effective utilization. A typical clip comprises a stem with two arms with distal teeth. The design might vary; for instance, the arms' shape and number could differ, and so can the length of the stem. This length variation affects their use in narrow areas like small bowel strictures or esophageal stenosis. For example, a longer stem in a small bowel stricture could exacerbate the condition by rubbing against the mucosa on the opposite side. It’s imperative that we understand the anatomy to ensure the appropriate selection and use of these clips.
Advancing and Applying Clips with Precision: The advancement and application of these Through-The-Scope clips demand precision and care. When initially advancing the clip into the working channel of the scope, it's crucial to hold close to the tip to prevent bending the arm. Once the clip has navigated through the working channel and reaches the tip of the scope, it should be gently pushed out, opened, and pulled back towards the scope. For example, when addressing a bleeding lesion, the clip should be open and advanced towards the lesion by moving the endoscope. And at that pivotal moment, when the clip is near the target vessel or defect to be closed, it should be pushed out with the hand, then closed and released by the assistant. This meticulous handling and application of clips can significantly bolster patient outcomes.
Mastering the Use of Clips: The art of mastering the use of clips lies in a thorough understanding of their anatomy, their mechanics, and the knack of deploying them accurately, and applying them with precision. It's a journey of practice and learning that unveils the full potential of these versatile tools, thereby elevating patient care to new heights.
Conclusion: The Gastroenterology & Endoscopy field continually evolves with advancements like Hemoclips, pushing the boundaries and offering new horizons for better patient care. Mastering the use of these clips is not just about enhancing procedural efficiency but also about ensuring safer and improved patient outcomes.

16 Jan 2024
00:02:26
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:
Expansile Memory Snares: These snares are particularly notable. I favor using snares equipped with a robust expansile memory. This feature ensures the snare retains its shape and efficiency even after multiple uses.
Hexagonal or Oval Snares with Double Buckles: Snares of this design tend to maintain an expanded state very effectively. This characteristic is valuable in ensuring consistent performance over repeated procedures.
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:
Lesion Size and Shape: The dimensions and morphology of the lesion dictate the type of snare required.
Snare Memory and Durability: A snare that retains its shape after multiple uses is highly beneficial.
Personal Comfort and Skill: Ultimately, the choice often boils down to what the endoscopist finds most efficient and comfortable to use.
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.
