Endoscopic diverticulotomy with a stapler can be an effective and safe treatment for Killian-Jamieson diverticulum

Peroral endoscopic myotomy as a treatment for Killian-Jamieson diverticulum (KJ-POEM)

Background and study aims Killian-Jamieson diverticulum (KJD) is a rare type of esophageal diverticulum that occurs in a specific area called the Killian-Jamieson space. Although surgery has been the conventional treatment for symptomatic KJD, minimally invasive endoscopic techniques, particularly Killian-Jamieson per-oral endoscopic myotomy (KJ-POEM), have emerged as an alternative. The aim of the study was to evaluate the effectiveness and safety of KJ-POEM in treating KJD. Patients and methods This was an international, multicenter, retrospective study that included patients who underwent KJ-POEM for symptomatic KJD from October 16, 2018 to April 12,2023. The primary outcome was clinical success, defined as complete or near-complete resolution of symptoms (i.e., post-procedure Kothari-Haber Score ≤ 2).  Secondary outcomes were technical success (defined as successful completion of all procedural steps), rate and severity of adverse events (AEs), total procedure duration, and symptom recurrence during follow-up. Results A total of 13 patients (mean age 65.23 years, 6 female) with KJD and a mean pre-procedure Kothari-Haber Score of 6 (standard deviation [SD] 2.16) underwent KJ-POEM across 10 participating centers. Clinical success and technical success were achieved in all cases (100%) with a mean post-procedure Kothari-Haber Score of 0.91 (SD 0.99). There were no AEs and no cases of injury to the recurrent laryngeal nerve. Mean length of hospital stay was 1.09 days (SD 0.74). Mean follow-up time was 9.41 months (SD 10.07) post-procedure. There was no post-procedure symptom recurrence any patient. Conclusions KJ-POEM is a safe and effective alternative treatment for symptomatic KJD with excellent short/mid-term outcomes.

Killian-Jamieson diverticulum: A rare cause of dysphagia

Pharyngoesophageal diverticula are a rare anatomical abnormality and are classified in 3 types based on the area of their protrusion: Zenker diverticulum is the most common, followed by Killian-Jamieson diverticulum and the rarest, Laimer diverticulum. We report a case of a 68-year-old man who presented to our clinic with a 3-year history of moderate anemia uncovered after routine blood tests, progressive dysphagia for solids and food bolus impactions resolved spontaneously. Upper endoscopy revealed a wide-mouthed diverticulum, measuring 2-3 cm, with normal mucosa and food residue inside, just below the upper esophageal sphincter, on the left side of the esophageal wall and also hiatal hernia with diffuse mucosal bleeding. Subsequent barium swallow study showed as well a 25 mm left-sided outpouching arising from the anterolateral wall of the proximal cervical esophagus, consistent with a Killian-Jamieson diverticulum. Killian-Jamieson diverticulum is a rare condition with a highly variable clinical presentation, most often reported symptoms being dysphagia, regurgitation and globus sensation.

Killian Jamieson Diverticulum, the Great Mimicker: A Case Series and Contemporary Review

OBJECTIVE

To assess barium esophagram (BAS) as a diagnostic marker for patients with Killian Jamieson diverticula (KJD).

METHODS

Prospective, multicenter cohort study of individuals enrolled in the Prospective OUtcomes of Cricopharyngeus Hypertonicity (POUCH) Collaborative. Patient demographics, comorbidities, radiographic imaging reports, laryngoscopy findings, patient-reported outcome measures (PROM), and operative reporting were abstracted from a REDCap database and summarized using means, medians, percentages, frequencies. Paired t-tests and Wilcoxon Signed Rank test were used to test pre- to post-operative differences in RSI, EAT-10, and VHI-10 scores. Diagnostic test evaluation including sensitivity, specificity, positive, and negative predictive value with 95% confidence intervals were calculated comparing BAS findings to operative report.

RESULTS

A total of 287 persons were enrolled; 13 (4%) patients were identified with confirmed KJD on operative reports. 100% underwent open transcervical excision. BAS has a 46.2% (95% confidence interval [CI]: 23.2, 70.9) sensitivity and 97.8% (95% CI: 95.3, 99.0) specificity in detecting a KJD and 50% (95% CI: 25.4, 74.6) positive predictive value but 97.4% (95%CI: 94.8, 98.7) negative predictive value. Preoperatively, patients reported mean (SD) RSI and EAT-10 of 19.4 (9) and 8.3 (7.5) accordingly. Postoperatively, patients reported mean (SD) RSI and EAT-10 as 5.4 (6.2) and 2.3 (3.3). Both changes in RSI and EAT-10 were statistically significant (p = 0.008, p = 0.03).

CONCLUSION

KJD are rare and represent <5% of hypopharyngeal diverticula undergoing surgical intervention. Open transcervical surgery significantly improves symptoms of dysphagia. BAS has high specificity but low sensitivity in detecting KJD.

Rare Association of Killian-Jamieson Diverticulum and Peptic Stricture of the Esophagus: Is It Causal or Casual?

Killian-Jamieson diverticulum (KJD) is a rare esophageal diverticulum that arises from the anterolateral wall of the proximal cervical esophagus in the Killian-Jamieson space. Although rare presentations include dysphagia, globus sensation, or a suspected thyroid nodule, it is often asymptomatic. Treatment is indicated only in symptomatic cases. We report a 55-year-old female who had long-standing heartburn and presents now with dysphagia, weight loss, and anemia. Imaging and upper endoscopy revealed peptic stricture and an associated KJD. She underwent serial endoscopic dilatation of the peptic stricture and was symptomatically better afterwards. She is currently doing well on follow-up.

Per-oral endoscopic myotomy as treatment for Killian-Jamieson diverticulum

Killian-Jamieson diverticulum (KJD) is a rare type of esophageal diverticulum less commonly encountered compared with Zenker's diverticulum (ZD). Endoscopic approach for these diverticula has been rapidly evolving. Currently, a flexible endoscopic septum division is considered the first-line treatment for symptomatic ZD patients, however reported recurrence rates are over 10% according to recent literature. With the advent of submucosal tunneling technique established by per-oral endoscopic myotomy for achalasia, it has been applied to treat ZD named as Zenker's diverticulum per-oral endoscopic myotomy (Z-POEM) as a minimally invasive treatment. Although there are very few reports utilizing submucosal tunneling approach to KJD, we have opted to perform Z-POEM in order to safely perform complete dissection of the muscle septum while maintaining mucosal integration. Due to the difficulty of anatomical location of KJD, we created mucosal incision and subsequent submucosal tunnel directly at the level of the septum as opposed to creating a submucosal tunnel few centimeters proximal to the septum as being previously proposed. We report a case in which this technique was successfully performed with complete resolution of dysphagia without any adverse event. This technique permits to perform complete myotomies without the fear of causing perforation. Although larger cohorts are required to assess its safety and efficacy, Z-POEM to treat KJD seems to be promising.

Killian Jamieson Diverticulum: A Rare Cause of Dysphagia

Killian-Jamieson diverticula (KJD) and Zenker’s diverticula (more common) share similar pathophysiology but are considered to be different types of phrenoesophageal diverticula.

A 55-year-old female presented to the clinic with chronic dysphagia, halitosis, and regurgitation. Imaging modalities confirmed a Killian-Jamieson diverticulum, explaining her symptoms. She was offered different treatment options and decided to proceed with a less invasive endoscopic approach.

Physicians should be aware of the variable presentations of KJD and the different available treatments as newer techniques are becoming more popular and preferable by patients.

Killian-Jamieson diverticulum safely resected using a manual intraoperative neural monitoring system: a case report

BACKGROUND

Killian-Jamieson diverticulum is a rare pharyngoesophageal diverticulum. The risk of intraoperative injury of the recurrent laryngeal nerve (RLN) is high during surgical resection of Killian-Jamieson diverticulum because the RLN usually runs next to the base of the diverticulum. We present a case of Killian-Jamieson diverticulum that was safely resected with effective use of an intraoperative nerve monitoring (IONM) system with a handheld stimulating probe to prevent RLN injury.

CASE PRESENTATION

A 69-year-old man complaining of dysphagia was diagnosed with Killian-Jamieson diverticulum and underwent open transcervical diverticulectomy. Because the anterior aspect of the diverticulum was expected to be close to the RLN, the accurate location of the RLN was checked during dissection by intermittent stimulation using a handheld probe of the IONM system to avoid mechanical and thermal injury. The diverticulum was transected longitudinally using a linear stapler, and the staple line was buried using absorbable sutures from the distal end. During its closure, RLN was identified very close to the diverticulum stump by IONM, and the upper side of the stump was left unburied to avoid RLN injury. The postoperative course was uneventful and the patient was discharged on postoperative day 7. Postoperative evaluation showed no vocal cord paralysis.

CONCLUSION

IONM may be beneficial during open surgery for Killian-Jamieson diverticulum, which usually protrudes just lateral to the RLN.

Surgery for Killian-Jamieson diverticulum: a report of two cases

BACKGROUND

Killian-Jamieson diverticulum (KJD) is a rare diverticulum arising from a muscular gap in the anterolateral wall of the proximal cervical esophagus. The first choice of treatment for KJD remains controversial due to its rare incidence. Here, we report two cases of KJD for which we performed different surgery: diverticulectomy in one case and diverticulopexy in the other.

CASE PRESENTATION

Case 1 involved a 58-year-old woman presenting progressive pharyngeal discomfort for the past year. She was diagnosed as KJD using endoscopic and radiographic findings. She underwent diverticulectomy with cricopharyngeal and proximal esophageal myotomy. Staple line leakage developed at 1 month after surgery and was successfully treated conservatively. At 5 months after surgery, she was asymptomatic. Case 2 involved a 77-year-old woman presenting dysphagia for the past 2 years. She had a history of bilateral breast cancer and had hypertension, asthma, and osteoporosis. Taking her age and medical history into account, we selected diverticulopexy with cricopharyngeal and proximal esophageal myotomy. The postoperative course was uneventful. At 2 years after surgery, she remained free of dysphagia.

CONCLUSION

The first choice of surgery for KJD is diverticulectomy. In a high-risk patient, diverticulopexy is a reasonable treatment. We recommend the addition of myotomy as a part of any surgical treatment.

Presentation and Management of Killian Jamieson Diverticulum: A Comprehensive Literature Review

Objective:

To examine the clinical presentation, diagnostic evaluation, and management of Killian–Jamieson diverticula (KJD) through literature review.

Methods:

A comprehensive literature review was conducted through December 2018 using keywords Killian–Jamieson diverticula/diverticulum. Data extracted included clinical presentation, imaging characteristics, surgical management, and postoperative care.

Sources:

PubMed and Google Scholar.

Results:

Sixty-eight cases of KJD in 59 reports (29M:39F; median 58 years old) were identified for review. The most common presentation was dysphagia (n = 39), suspected thyroid nodule (n = 24) and globus (n = 14). The majority of KJD (n = 51) occur on the left, with rare reports of right side (n = 11) and bilateral (n = 5) presentation. Thirty-two cases describe surgical management: 22 utilizing a transcervical approach, with (n = 13) or without (n = 9) cricopharyngeal myotomy; and 10 reported endoscopic surgery. Diverticula managed transcervically averaged 3.8 cm in size in comparison to average 2.8 cm in the endoscopic group. Time to diet initiation after transcervical surgery averaged 4 days versus 2 days after endoscopic surgery. Complications were reported in 2/68 cases; both were diverticula recurrence after endoscopic surgery.

Conclusion:

Killian–Jamieson diverticula is a rare diagnosis that should be considered in the evaluation of dysphagia, globus, and also suspected thyroid nodule. When patient symptoms warrant intervention, a transcervical approach, with or without cricopharyngeal myotomy, is most commonly utilized. In recent years, an endoscopic approach has been presented as an alternative for smaller diverticula. Further understanding of the optimal treatment and postoperative management for KJD requires larger cohorts.
