Incidence of brain metastasis from esophageal cancer.

We investigated whether the incidence of brain metastasis (BM) from primary esophageal and esophagogastric cancer is increasing. A single-institution retrospective review identified 583 patients treated from January 1997 to January 2016 for stages I through IV cancer of the esophagus and esophagogastric junction (follow-up, ≥3 months). Collected data included demographic information, date and staging at primary diagnosis, histologic subtype, treatment regimen for primary lesion, date of BM diagnosis, presence or absence of central nervous system symptoms, presence or absence of extracranial disease, treatment regimen for intracranial lesions, and date of death. The overall cohort included 495 patients (85%) with adenocarcinoma and 82 (14%) with squamous cell carcinoma (492 [84%] were male; median age at diagnosis, 68 years [range: 26-90 years]). BM was identified in 22 patients (3.8%) (median latency after primary diagnosis, 11 months). Among patients with BM, the primary histology was adenocarcinoma in 21 and squamous cell carcinoma in 1 (P = 0.30). BM developed in 12 who were initially treated for locally advanced disease and in 10 stage IV patients who presented with distant metastases. Overall survival (OS) after BM diagnosis was 18% at 1 year (median, 4 months). No difference in OS after BM diagnosis was observed in patients initially treated for localized disease compared to patients who presented with stage IV disease; however, OS was superior for patients who initially had surgical resection compared to patients treated with whole brain radiotherapy or stereotactic radiosurgery alone (1-year OS, 67% vs. 0%; median OS, 13.5 vs. 3 months; P = 0.003). The incidence of BM is low in patients with esophageal cancer. Outcomes were poor overall for patients with BM, but patients who underwent neurosurgical resection had improved survival.

The clinical behavior of desmoplastic melanoma.

BACKGROUND: Desmoplastic melanoma (DM) is a rare variant of malignant melanoma. A better understanding of the clinical course of DM will impact on its treatment. METHODS: We reviewed the medical records of 59 patients with DM seen at the Mayo Clinics Scottsdale and Rochester since 1985. RESULTS: Thirty-seven (63%) patients were male with a mean age of 62.8 years. The mean DM thickness was 6.5 mm. A total of 23 patients (39%) experienced local recurrence (LR). LR correlated with positive, unknown, or <1 cm margins. Fifty percent of patients who locally recurred subsequently developed metastatic disease. No patients were found to have positive nodal disease during ELND (16) or SLN biopsy (12). Only 1 patient (2%) developed delayed regional node metastases. Sixteen patients developed metastatic disease. The most common site was the lungs (81%). CONCLUSIONS: LR is a significant problem and correlates with an increased risk of systemic metastatic disease. With the rare occurrence of lymphatic spread, we recommend patients undergo SLN biopsy only. DM appears to preferentially metastasize to the lungs and should be targeted when evaluating the patient for metastatic disease.

Laparoscopic splenectomy for the treatment of gastric varices secondary to sinistral portal hypertension.

Portal hypertension presents significant challenges to the laparoscopic surgeon. Here we review the case of a successful laparoscopic splenectomy in a patient with sinistral portal hypertension. The value of preoperative splenic artery embolization is highlighted.

Experience with FiberWire for pectus bar attachment.

BACKGROUND: Minimally invasive repair of pectus excavatum has become an established method for repair of pectus excavatum. Bar displacement or rotation remains the most common complication of this repair requiring return to the operating room. METHODS: Retrospective review of all patients at a single institution who underwent repair of pectus excavatum using FiberWire for bar stabilization between December 2009 and March 2013 was undertaken. RESULTS: 93 patients underwent minimally invasive pectus repair using FiberWire during the study period. The patients included 73 males and 20 females, with an average age of 14.6years (range 7-21years). Mean operative time was 102minutes (range 56-198minutes). No patients developed wound complications, two patients developed pain because of bar migration and required return to the OR, and no patients had recurrence of their pectus defect because of bar migration during the study period. Median length of follow-up was 17months (range 3-36months). CONCLUSION: Stabilization of pectus bars using circumferential rib fixation with FiberWire at multiple points on both sides of the bar appears to be effective in preventing bar rotation and displacement, and requires minimal change to the operation as it has been previously described. Early experience shows a low rate of complications.
