ABSTRACT

Objective@#To analyze the risk factors of cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.@*Methods@#530 patients with esophageal cancer underwent thoracoscopic-lapacoscopic esophagectomy at the Cancer Hospital, Chinese Academy of Medical Sciences from Jan 2011 to Dec 2015. The demographic, surgical and clinical data of patients were retrospectively analyzed. Multivariate logistic regression was used to evaluate risk factors of cervical anastomotic leakage in these patients.@*Results@#A total of 530 patients undergoing thoracoscopic-lapacoscopic esophagectomy were enrolled in this study. There were 421 males and 109 females. The mean age was (59.40±8.08) years old, and 91 patients with cervical anastomotic leakage. Sigle factor analysis revealed that the risk grading by American Society of Aneshesiologists, previous history of chest surgery, respiratory comorbidity, diffusion capacity for carbon monoxide of the lung, operation time, anastomosis, average days of postoperative hospitalization, death within 30 days after surgery, respiratory complications, pleural effusion or empyema, and poor healing of the incision were statistically associated with cervical anastomotic leakage (all P<0.05). Multivariate analysis showed that previous history of chest surgery, hepatic insufficiency, manual anastomosis, prolonged postoperative hospitalization, and poor healing of the incision were independent risk factors for cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy (all P<0.05).@*Conclusions@#Previous history of chest surgery, hepatic insufficiency, poor healing of the incision, manual anastomosis and prolonged postoperative hospitalization were significantly associated with cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. It′s important to strengthen perioperative nursing and surgical techniques to prevent anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.

ABSTRACT

Objective@#To compare intravascular ultrasound (IVUS) with venography in the intraoperative evaluation of iliac vein compression syndrome (IVCS).@*Methods@#From Sep 2017 to Mar 2018, consecutive patients with suspicious iliac vein compression, underwent both venography and IVUS. The results were compared between IVUS and venography.@*Results@#40 patients with 48 limbs were enrolled. Venography underestimated both the diameter and area stenosis compared with IVUS (39.63%±15.48% vs. 64.97%±16.42%, P<0.001; 51.83%±18.23% vs. 59.19%±14.17%, P=0.021, respectively). The eccentricity detected by venography was lower than IVUS (0.69±0.17 vs. 0.93±0.17, P<0.001). Taking IVUS as gold standard, the sensitivity and the specificity of venography for detecting a ≥50% stenosis was 18.92% and 81.82%, and the intertechnique agreement was extremely low between venography and IVUS (κ=0.004).@*Conclusion@#Compared with IVUS, venography underestimated the degree of stenosis in IVCS. The sensitivity of venography in detecting a significant stenosis was very low.

ABSTRACT

The classification and treatment patterns of adenocarcinoma of esophagogastric junction (AEG)do not comply with the"gold standard"for its unique anatomical location and biological characteristics. With an increasing incidence rate of AEG in recent years, the importance of AEG in public health has caught much attention. Surgery is considered as the first choice for the treatment of AEG, but surgical treatments for different types of AEG is still controversial. Many clinical trials have proved the adjuvant therapy and neoadjuvant therapy are beneficial to the improvement of surgical resection and survival rate. Molecular targeted drugs might bring light for the treatment of advanced AEG. Individual therapy of AEG has become increasingly important with the development of science and technology and the results of large clinical researches published. This article reviews the latest progress of surgery-prioritized multimodality therapy for AEG.

ABSTRACT

Objective@#To analyze risk factors of anastomotic leakage after McKeown'sesophagectomy.@*Methods@#The clinical data of 635 esophageal cancer patients, who underwent McKeown's esophagectomy at Cancer Hospital of Chinese Academy of Medical Sciences from January 2012 to December 2015, were retrospectively analyzed. The risk factors of cervical anastomotic leakage were identified through analysis of medical history, surgical procedure, tumor characteristics and vascular calcification.@*Results@#Among all the 635 patients, anastomotic leakage occurred in 111 (17.5%)patients. Univariate analysis showed that the American Society of Anesthesiologists (ASA) risk class, prior thoracic surgery, upper digestive tract ulcer, COPD, hypertension, peripheral vascular disease, renal insufficiency, FEV1% predicted, DLCO% predicted, duration of surgery and calcification of descending aorta, celiac trunk and left postceliac arteries were associated with a statistically significant increase in risk of cervical anastomotic leakage (P<0.05 for all). Logistic regression analysis showed that ASA risk class, peripheral vascular disease, renal insufficiency and calcification of descending aorta and celiac trunk were independent risk factors of cervical anastomotic leakage after McKeown's esophagectomy (P<0.05 for all).@*Conclusions@#ASA risk class, peripheral vascular disease, renal insufficiency, calcification of descending aorta and celiac trunk are independent risk factors of cervical esophageal anastomotic leakage after McKeown's esophagectomy.
