Endoscopic management of a bleeding Zenker's diverticulum: A case report.
Article in International journal of surgery case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionBleeding from a Zenker's diverticulum is a rare occurrence, and currently no formal guidelines exist for its management. It is a potentially life-threatening condition and an important consideration in the differential diagnosis of haemoptysis or haematemesis. PRESENTATION OF CASE: A 63-year-old man presented with haemoptysis and haematemesis while on dual antiplatelet therapy for a recent NSTEMI. After resuscitation he underwent a CT angiogram which demonstrated an active contrast blush and pooling of contrast in a pharyngeal diverticulum. At endoscopy a large Zenker's diverticulum was encountered which contained an ulcerated area with general oozing of blood from multiple points and a single brisk bleeding point. Haemostasis was achieved with two syringes of a topical haemostatic agent. DISCUSSION: Less than 15 case reports exist in the literature of this clinical entity, and fewer still have been managed successfully via endoscopic methods. The pathophysiology is unclear however may be related to antiplatelet agents exerting a topical effect after lodging in the diverticulum, causing ulceration, diverticulitis and bleeding. Early diagnosis can be challenging as patients may seem to present with haemoptysis, and delay to prompt diagnosis may further delay management.
conclusionThis is the first Australian case report of bleeding from a Zenker's diverticulum who underwent successful endoscopic management. It highlights the diagnostic dilemma presented by this clinical entity and the subsequent impacts on management. Endoscopic haemostasis is an ideal intervention either as a definitive procedure in elderly patients unfit for surgery, or initial management as a bridge to surgery.
