Novel Mediastinoscope-Assisted Minimally Invasive Esophagectomy for Esophageal Cancer: A Systematic Review and Meta-analysis.

BACKGROUND: Minimally invasive surgery is an expanding field of surgery that has replaced many open surgical techniques. Surgery remains a cornerstone in the treatment of esophageal cancer, yet it is still associated with significant morbidity and technical difficulties. Mediastinoscope-assisted esophagectomy is a promising technique that aims to decrease the surgical burden and enhance recovery. METHODS: PubMed, MEDLINE, and EMBASE databases were searched for publications on mediastinoscope-assisted esophagectomies for esophageal cancer. The primary endpoint was a postoperative anastomotic leak, while secondary endpoints were assessment of harvested lymph nodes (LNs), blood loss, chyle leak, hospital length of stay (LOS), operative (OR) time, pneumonia, wound infection, mortality, and microscopic positive margin (R1). The pooled event rate (PER) and pooled mean were calculated for binary and continuous outcomes respectively. RESULTS: Twenty-six out of the 2274 searched studies were included. The pooled event rate (PER) for anastomotic leak was 0.145 (0.1144; 0.1828). The PERs for chyle leak, recurrent laryngeal nerve injury/hoarseness, postoperative pneumonia, wound infection, early mortality, postoperative morbidity, and microscopically positive (R1) resection margins were 0.027, 0.185, 0.09, 0.083, 0.020, 0.378, and 0.037 respectively. The pooled means for blood loss, hospital stay, operative time, number of total harvested LNs, and number of harvested thoracic LNs were 159.209, 15.187, 311.116, 23.379, and 15.458 respectively. CONCLUSIONS: Mediastinoscopic esophagectomy is a promising minimally invasive technique, avoiding thoracotomy, patient repositioning, and lung manipulation; thus allowing for shorter surgery, decreased blood loss, and decreased postoperative morbidity. It can also be reliable in terms of oncological safety and LN dissection.

Prevalence of neurological complaints among emergency department patients with severe hypertension.

OBJECTIVE: Severe hypertension can accompany neurological symptoms without obvious signs of target organ damage. However, acute cerebrovascular events can also be a cause and consequence of severe hypertension. We therefore use US population-level data to determine prevalence and clinical characteristics of patients with severe hypertension and neurological complaints. METHODS: We used nationally representative data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) collected in 2016-2019 to identify adult ED patients with severely elevated blood pressure (BP) defined as systolic BP ≥ 180 mmHg and/or diastolic BP ≥120 mmHg. We used ED reason for visit data fields to define neurological complaints and used diagnosis data fields to define acute target organ damage. We applied survey visit weights to obtain national estimates. RESULTS: Based on 5083 observations, an estimated 40.4 million patients (95% CI: 37.5-43.0 million) in EDs nationwide from 2016 to 2019 had severe hypertension, equating to 6.1% (95% CI: 5.7-6.5%) of all ED visits. Only 2.8% (95% CI: 2.0-3.9%) of ED patients with severe hypertension were diagnosed with acute cerebrovascular disease; hypertensive urgency was diagnosed in 92.0% (95% CI: 90.3-93.4%). Neurological complaints were frequent in both patients with (75.6%) and without (19.9%) cerebrovascular diagnoses. Hypertensive urgency patients with neurological complaints were more often older, female, had prior stroke/TIA, and had neuroimaging than patients without these complaints. Non-migraine headache and vertigo were the most common neurological complaints recorded. CONCLUSION: In a nationally representative survey, one-in-sixteen ED patients had severely elevated BP and one-fifth of those patients had neurological complaints.

Rates of Acute Brain Injury Among Severely Hypertensive Patients Seen in the Emergency Department.

Background: Identifying patients with acute brain injury among patients who present to the Emergency Department (ED) with severe hypertension can be challenging. We explored rates of brain injury in a cohort of ED patients with severe hypertension in whom acute target-organ damage was or was not initially suspected. Methods: We conducted a retrospective chart-review study at two different hospitals within the same urban health system. Consecutive adult patients seen from 10/1/2020 to 5/1/2022 with a systolic blood pressure ≥180 mmHg or diastolic blood pressure ≥120 mmHg were included. Results: A total of 972 patients met our eligibility criteria. The average age was 59 years (SD: 16.5), 454 (46.7%) were women, and 582 (59.9%) were non-White. A total of 186/972 (19.1%) patients were initially thought to have acute target-organ damage in the ED with 97/186 (52.2%) diagnosed with stroke or TIA. The remaining 786/972 (80.9%) patients were not initially diagnosed with target-organ damage (hypertensive urgency [HU]). Of the 786 patients with HU, a head CT was obtained in 216/786 (27.7%) and brain MRI in 74/786 (9.4%). Of the HU patients with a brain MRI, 23/74 (31.1%) had acute abnormalities; most abnormalities on brain MRI (17/23 [73.9%]) were not seen on preceding head CT. Conclusions: In a multicenter study of ED patients, nearly 1 in 5 patients though to have HU who eventually underwent brain MRI had unexpected acute neurological findings, though brain MR was obtained in only 9%.
