J Thorac Dis 2020 Dec;12(12):7117-7126

Background: This study analyzes the outcomes of a one-stage hybrid procedure combining thoracic endovascular aortic repair (TEVAR) with extra-anatomic bypass in patients with distal aortic arch disease.

Methods: This retrospective study collected 103 hybrid procedures combining TEVAR with extra-anatomic bypass (mean age, 62.2±9.3 years; 90 males) performed from January 2009 to January 2019 at Beijing Anzhen Hospital. We analyzed 30-day and mid-term outcomes including survival rate and the incidence of stroke, spinal cord injury (SCI), and endoleak.

Results: Five deaths (4.6%) occurred within 30 days, including type I endoleak in Zone 1 (n=1), hemorrhagic shock (n=1), stroke (n=2), and stent migration (n=1). Two patients developed SCI. The median follow-up time was 39.5 (interquartile range, 13.6-69.0) months. In all, 14 late deaths occurred; these were due to stroke (n=2), severe pneumonia (n=1), aortic rupture caused by type I endoleak (n=3), and sudden death (n=8). Six late endoleaks occurred including three type I and one type II in Zone 1 and two type I in Zone 2. In a competing risks analysis, the incidences of reintervention at 7 years, late death, and survival without reintervention were 8%, 22%, and 70%, respectively. In a Cox risk model, stroke (HR, 21.602; 95% CI: 2.798-166.796; P=0.003) was the only risk factor for 30-day mortality. Stroke (HR, 19.484; 95% CI: 5.245-72.380; P<0.001), SCI (HR, 15.548; 95% CI: 2.754-87.786; P=0.002), and endoleak (HR, 4.626; 95% CI: 1.068-20.040; P=0.041) were independent risk factors for long-term mortality.

Conclusions: The one-stage hybrid procedure provides acceptable mid-term results with good mid-term patency of extra-anatomic bypass. Strict selection of patients suitable for hybrid repair can effectively improve the survival rate and reduce the incidence of complications. At the same time, close follow-up patients should receive close long-term follow-up after hybrid procedure.

Risk Factors for Mortality in Patients with Aortoesophageal Fistula Related to Aortic Lesions.

Gastroenterol Res Pract 2020 17;2020:4850287. Epub 2020 Sep 17.

Department of Gastroenterology, Beijing Anzhen Hospital, Capital Medical University, Beijing, China.

Objective: Aortoesophageal fistula (AEF) related to aortic aneurysm and dissection is an uncommon but life-threatening condition. We performed a systematic review of risk factors for mortality and factors associated with the prognosis of AEF.

Methods: A systematic search of the PubMed, Embase, and Cochrane Library databases was performed. Clinical characteristics, diagnostic methods, and treatments were assessed in terms of their ability to predict mortality.

Results: The systematic review identified 184 eligible articles including 219 patients with AEF. Multivariable Cox regression revealed positive correlations of hemorrhagic shock (hazard ratio (HR): 1.824, 95% CI: 1.217-2.735, = 0.004), sepsis (HR: 1.714, 95% CI: 1.112-2.641, = 0.015), multiorgan failure (HR: 3.060, 95% CI: 1.470-6.368, = 0.003), and conservative treatment (HR: 5.257, 95% CI: 3.405-8.116, < 0.001) with mortality and a negative correlation between combination therapy (aortic graft replacement and esophagectomy) and mortality (HR: 0.319, 95% CI: 0.125-0.813, = 0.017). Kaplan-Meier survival analysis showed that the 1-year cumulative survival rate was 42.5 ± 3.8%. The overall fistula-related mortality rate was 47.0% (103/219). The most common causes of death were bleeding (54.9%) and infection (29.2%).

Conclusions: We found that hemorrhagic shock, sepsis, and multiorgan failure were risk factors for death in patients with AEF. Additionally, conservative treatment was associated with a higher rate of mortality, while combined aortic graft replacement and esophagectomy improved the prognosis.

Eighty-six cases of laparoscopic vaginoplasty using an ileal segment.

Chin Med J (Engl) 2009 Aug;122(16):1862-6

Department of General Surgery, Beijing Anzhen Hospital of Capital Medical University, Beijing, China.

Background: The surgical management of the absence of the vagina is a complex problem and constitutes a significant technical challenge. As the laparoscopy has been an important tool for the treatment of uterovaginal anomalies, we evaluated the feasibility of laparoscopic vaginoplasty using an ileal segment retrospectively.

Methods: Totally 86 patients who underwent laparoscopic vaginoplasty using an ileal segment in Beijing Anzhen Hospital during February 2004 to July 2007 were enrolled in this study. Of the 86 patients, 70 (81.4%) underwent primary operations and 16 (18.6%) secondary operations. Nineteen (22.1%) patients underwent total laparoscopic vaginoplasty and 67 (77.9%) patients underwent laparoscope-assisted vaginoplasty. The operation time, cost of hospitalization, and hospital duration were compared between the two laparoscopic groups. The Student's t test and the Mann-Whitney test were used to examine the differences.

Results: All the surgeries were successfully completed with no any intraoperative complication. There were three major surgical complications in the postoperative period: one case of intra-abdominal hemorrhage, one case of meatal stenosis, and one case of intestinal obstruction. The mean follow-up period of this series was 18 months. Seventy-eight patients were satisfied with their sexual lives after the surgeries except 5 women complaining of vaginal stenosis and 3 with no sexual partner during the follow-up. Significant differences were obtained between total laparoscopic and laparoscope-assisted vaginoplasty groups, such as the operation time, cost of hospitalization, and hospital duration (P < 0.01). There were no significant differences in sexual function between the two groups.

Conclusions: The laparoscopic vaginoplasty using an ileal segment is satisfactory for cosmetic, functional, and anatomic results. Vaginoplasty with an ileal segment, performed by either total laparoscopic or laparoscope-assisted techniques, has a high success rate for a functional vagina.
