A rare cause of dysphagia and simultaneous hoarseness of voice in the octogenarian: a Killian-Jamieson diverticulum, management, and review of literature.

An 82-year-old male presented with progressive dysphagia and simultaneous hoarseness of voice for the past 6 months. He had mitral valve repair and a permanent pacemaker for a heart block 5 years ago. A computed tomographic scan of the neck demonstrated a cervical esophageal diverticulum. Oral Gastrogrifin contrast study confirmed esophageal diverticulum in Killian-Jamieson space. Open surgical diverticulectomy was performed safely. Patient's dysphagia resolved immediately, and he regained his normal voice after 6 weeks. Introduction: Killian-Jamieson's esophageal diverticulum is a rare form of pulsion diverticulum which originate through a muscular gap in the anterolateral wall of the esophagus, inferior to the cricopharyngeus muscle and superior to the circular and longitudinal muscle of the esophagus. Killian-Jamieson defined this area where the recurrent laryngeal nerve enters the pharynx, called Killian-Jamieson triangle. Ekberg and Nylander, in 1983, described an esophageal diverticulum in Killian-Jamieson space. The most common clinical manifestations in such patients are dysphagia, cough, epigastric pain, recurrent respiratory tract infections, and rarely hoarseness of voice. In symptomatic patients, surgical or endoscopic resection of the diverticulum is mandatory. We report this case in line with SCARE (Surgical CAse REport) criteria. Case Report: An 82-year-old male presented to our outpatient clinic with a history of progressive dysphagia for solid food and hoarseness of voice for the last 6 months. He denied gastroesophageal reflux, cough, and shortness of breath. On examination of the neck, there was swelling on the left side but no tenderness or lymphadenopathy. Basic blood investigations, including complete blood count, liver, and renal panels, were normal. An echocardiogram showed mild impairment of left ventricle function and normally functioning mitral valve. Chest X-ray showed a pacemaker in position. Computed tomography scan of the neck showed esophageal diverticulum. Gastrogrifin contrast study showed esophageal Killian-Jamieson diverticulum (KJD). Discussion: The acquired esophageal diverticulum is categorized into three types based on its anatomical location. Zenker's and Killian-Jamieson (pulsion diverticulum) in the proximal part, traction diverticulum in the middle part, due to pulling from fibrous adhesions following the lymph node infection and epiphanic pulsion type in the distal esophagus. Although the KJD and Zenker's diverticulum (ZD) arise close to each other in the pharyngoesophageal area, they are anatomically distinct. Although ZD and KJD have the same demographic features, they are more commonly found in older men (60-80 years) and women, respectively. The incidence of ZD is 0.01-0.11%, and KJD is 0.025% of the population. Rubesin et al. reported radiographic findings in 16 KJD cases. They found the majority of them were on the left side (72%), followed by 20% on the right side and 8% bilateral. Conclusion: In conclusion, we report a rare case of dysphagia and simultaneous hoarseness of voice in an octogenarian due to KJD, who was treated with open diverticulectomy, and dysphagia resolved; he regained his voice back after 6 weeks. In our opinion, endoscopic surgery in such a patient with KJD can put recurrent laryngeal at risk of injury since an endoscopic approach operator cannot visualize and dissect away the recurrent laryngeal nerve, particularly when KJD already compresses it.

The diagnostic and prognostic value of tumor markers in giant mediastinal endodermal sinus tumor with prolonged survival: Twelve-year follow up after radical resection.

We report a case of 16 -year male who presented with nonproductive cough, chest pain, and hemoptysis. His chest -x-ray and computerized tomographic scan (CT) of the thorax with contrast enhancement revealed a large mediastinal mass mostly occupying the left hemithorax. Percutaneous CT scan-guided biopsy of the mediastinal mass was reported as an endodermal sinus tumor (EDST). Serum alpha-fetoprotein levels were markedly raised (120,000 ng/ml). After completion of chemotherapy repeat, CT scan of the thorax revealed a large residual mass. Radical resection of the tumor was carried out. Twelve-year post-surgical resection follow-up with serial serum alpha-fetoprotein (AFP) tumor marker levels and CT scan of the thorax showed no recurrence.

Extended pattern prostate biopsy does not minimize the volume-grade bias in prostate cancer detection.

PURPOSE: The higher number of high grade cancers noted in the Prostate Cancer Prevention Trial may have arisen due to a previously unknown association between prostate volume and sextant biopsy derived grade, rendering it more difficult to detect high grade cancer in men with a larger prostate (volume-grade bias). A basic tenet of measurement theory is that repeat measurement improves validity. We determined whether an extended pattern prostate biopsy technique could overcome this bias. MATERIALS AND METHODS: We reviewed the record of 679 patients who underwent systematic extended (10 cores or greater) biopsy with isoechoic prostate transrectal ultrasound and prostate specific antigen less than 10 ng/ml. Since specimens were separately labeled, we were able to compare the grade of the first 6 cores vs that of the extended pattern. We determined the highest grade achieved using traditional sextant biopsy and the change induced by marginal samples across volume tertiles, hypothesizing that if upgrading did not occur by volume, additional biopsies would be ineffective for minimizing this bias. RESULTS: Prostate cancer detected using a 6-core technique revealed 179 of 679 cancers (26.4%) vs 240 of 679 (35.4%) using the extended core technique (p <0.001). The marginal cancer detection rate increased significantly as prostate volume increased. Cancer detection rates for the 1st, 2nd and 3rd tertiles of prostate volume were increased by 16 of 227, 17 of 226 and 28 of 226 cases, respectively (p = 0.05). With respect to Gleason score, upgrading from Gleason 6 to 7 was observed in 14 patients (7.9%) due to the additional procured cores (p <0.001). However there was no association among the various prostate volumes (p = 0.87). CONCLUSIONS: Although more high grade cancers are detected with extended pattern biopsy, there is no differential upgrading with respect to prostate volume. Based on these observations extended prostate sampling in trials of agents that decrease prostate volume would have minimal impact on volume-grade associations.

Stage I nonseminomatous germ cell tumors: the case for management by risk stratification.

For patients with clinical stage I nonseminomatous germ cell tumor (NSGCT), the therapeutic options after orchiectomy are retroperitoneal lymphadenectomy, surveillance, and chemotherapy. Ideally the option selected will be based on an individualized assessment of the estimated risk of progression based on prognostic factors, so called risk-adapted treatment, to reduce overall burden of therapy while maintaining survival. It is possible to identify patients at low risk of progression who can be followed by active surveillance initially. Prognostic factors for high risk, while well defined, do not identify all patients at risk and those that are destined to progress, can usually be salvaged with delayed therapy. Most centres recommend either surgery or primary chemotherapy for those defined as being at high risk for progression. Prognostic factors for high risk however, while well defined, do not identify all patients at risk and those that are destined to progress, can usually be salvaged with delayed therapy.
