ENDOSCOPIC OR OPEN DIVERTICULECTOMY (RECOGNITION & REFERRAL)[1st line] Adult An outpouching of the pharyngeal wall, mostly in older adults, causing dysphagia, regurgitation of undigested food, halitosis and aspiration. Small ones are watched: the article treats only a symptomatic lesion as needing anything at all, and says one under 2 centimetres rarely needs treatment. The definitive management of the rest is mechanical, not medical - a large diverticulum is an indication for surgery, though these patients are elderly and choosing who to operate on takes real care, and the operation may be open or endoscopic. What it must achieve is division of the cricopharyngeus muscle, to release the high-pressure zone and do away with the pouch. Refer to ENT or upper GI surgery. - Refer Peds Children follow the same pathway: recognise and refer. No primary-care medicine is implied. Source No dose - referral pathway, no medicine given in primary care Why An outpouching of the pharyngeal wall, mostly in older adults, causing dysphagia, regurgitation of undigested food, halitosis and aspiration. Small ones are watched: the article treats only a symptomatic lesion as needing anything at all, and says one under 2 centimetres rarely needs treatment. The definitive management of the rest is mechanical, not medical - a large diverticulum is an indication for surgery, though these patients are elderly and choosing who to operate on takes real care, and the operation may be open or endoscopic. What it must achieve is division of the cricopharyngeus muscle, to release the high-pressure zone and do away with the pouch. Refer to ENT or upper GI surgery. Caution Rare in Egyptian primary care. RED FLAG - There is a high risk of pulmonary aspiration, tracheal fistula formation, esophageal obstruction, or co-existing squamous cell carcinoma. Squamous cell carcinoma can coexist with the pouch and must be actively excluded - take a smoking history and ask about habitual consumption of very hot or very cold drinks. Arrange a swallowing assessment to gauge aspiration risk and a dietary review to establish which food consistencies are safe, and keep the patient off a flat supine position. Barium swallow with videofluoroscopy is the test that makes the diagnosis and shows the pouch's size, position and mucosal character. Because these patients are typically elderly, fitness for surgery needs careful assessment before referral is framed as a certainty. The condition worsens over time and can progress to aspiration, halitosis, chronic cough and hoarseness. This diagnosis is very unusual below the age of 40 - in a younger patient with dysphagia, look for another cause. Consider achalasia, GERD or Barrett oesophagus, oesophagitis, and acute stroke before settling on this diagnosis in a patient with dysphagia. No drug row is listed here because the article names exactly one drug, gives it no dose, and names it for a different problem sitting alongside this one: where a Zenker diverticulum comes with achalasia, it says botulinum toxin may ease the dysphagia. (Zenker Diverticulum - StatPearls - NCBI Bookshelf, NBK499996) Botulinum toxin has no monograph in any document held here, so nothing could be dosed even if the achalasia case applied. What can go wrong with the operation, so the consent conversation is honest: the article lists injury to the laryngeal nerve, bleeding, perforation of the oesophagus, and trauma to the oral cavity. (Zenker Diverticulum - StatPearls - NCBI Bookshelf, NBK499996) RED FLAG - Recurrent aspiration pneumonia, significant unintentional weight loss, or choking episodes.
