“…KJD protrudes from the Killian-Jamieson space, an area bounded inferiorly by the cricopharyngeus muscle and laterally by the longitudinal muscle of the esophagus [ 1 ]. This space is distinguished from ZD origination, Killian’s dehiscence (also known as Killian’s triangle), which is bordered superiorly by the inferior pharyngeal constrictor muscle and inferiorly by the cricopharyngeus [ 2 ]. The average size of KJD ranges between 2.8 and 3.8 cm [ 3 ].…”

Killian-Jamieson diverticulum (KJD) is a rare presentation of esophageal diverticulum. It is located beneath the cricopharyngeal muscle and arises laterally from the Killian-Jamieson space. The pathogenesis is postulated to be from increased intraluminal pressure. Most patients with KJD are typically asymptomatic; however, a common clinical presentation is dysphagia. Demographics of patients with KJD are typically elderly, in which the majority are female and over 50 years old. Due to less frequent diagnosis of KJD, there are a limited number of case studies compared to Zenker's diverticulum, the more common presentation of esophageal diverticulum. In this case study, we discuss an atypical case presentation in a young, African-American female.

“… 1 It occurs when the hypopharyngeal mucosa and submucosa herniate into the Killian triangle (the triangle between the transverse fibers of the cricopharyngeal muscle at the bottom and the fibers of the inferior pharyngeal constrictor muscle at the top). 2 Its prevalence rate is 0.01%-0.11%. 3 It is most commonly observed in older men (aged >70 years) and is usually asymptomatic.…”

Background/Aims: The efficacy and safety of Zenker’s peroral endoscopic myotomy (Z-POEM), a current method in the treatment of Zenker’s diverticulum (ZD), have been demonstrated in a limited number of studies and case reports. This study aimed to report our experience with the Z-POEM method. Materials and Methods: Patients with ZD who were treated with Z-POEM between January 2019 and March 2023 and had a follow-up period of at least 3 months were included in the study. Our primary endpoint was clinical success. A Kothari–Haber score (KHS) of 2 or less at 1 month postoperatively was defined as clinical success. Our secondary endpoints were adverse events and recurrence rates. Results: In total, 20 patients (males, 65%; mean age, 63 ± 14.4 years) were treated with Z-POEM. The mean ZD septum length was 33.7 (±11.04) mm. The technical success rate was 100% (20/20), and the clinical success rate was 95% (19/20). In 1 case with a large ZD (septum length of 60 mm), the mucosal septum, which was thought to cause partial persistence of symptoms, was treated by endoscopic septotomy. The mean KHS decreased significantly after Z-POEM (preoperative KHS: 7.3 and postoperative KHS: 0.15, P < .0001). The median follow-up period was 10 months (interquartile range, 3-39). No recurrence was observed in any case. Intraprocedural mild subcutaneous emphysema was observed in 4 (20%) cases. Emphysema regressed spontaneously in the postoperative period without any treatment. Conclusion: Zenker’s peroral endoscopic myotomy is a successful and reliable method in the treatment of ZD, with low recurrence rates.

Zenker’s diverticulum in an 85-year-old Ugandan man

Background Zenker’s diverticulum (ZD) is an uncommon disorder due to an outpouching of tissue through the Killian triangle that is thought to be caused by dysfunction of the cricopharyngeal muscle. Case presentation An 85-year-old male patient presented with odynophagia and dysphagia of initially solid food followed by fluids that was associated with a significant weight loss over a one-year period. Barium swallow videofluoroscopy demonstrated a posterior outpouching of proximal esophagus that was 2 cm from the epiglottis. With the diagnosis of medium sized ZD, the patient underwent endoscopy guided diverticulotomy. Six months after the procedure, he was asymptomatic and had gained weight. Conclusions Dysphagia and weight loss raises a clinical suspicion for a malignancy. Barium swallow examination is an inexpensive method for the diagnosis of ZD.
