Screening for upper gastrointestinal cancers with magnetically controlled capsule gastroscopy: a feasibility study.

BACKGROUND: The medical consortium is an intensive and disease-specific association that integrates tertiary public hospitals and medical examination centers in China. We aimed to evaluate the feasibility of the medical consortium for screening upper gastrointestinal (GI) cancers (MCSC) by magnetically controlled capsule gastroscopy (MCCG). METHODS: 6627 asymptomatic subjects underwent MCCG as part of health check-ups in the MCSC between March and November 2018. Relevant clinical data were collected and analyzed. RESULTS: The MCSC detected 32 patients with upper GI cancer (0.48 %) confirmed by pathology. The detection rate of early gastric cancer was 16.67 % (4 /24). Gastric polyps, ulcers, and submucosal tumors were found in 15.54 %, 3.76 %, and 3.17 % of subjects, respectively. The whole GI preparation and operation process were well tolerated. CONCLUSIONS: The MCSC was a feasible model for upper GI cancer screening, especially for asymptomatic subjects. Further prospective studies with better operational quality control are warranted.

Multivariate regression analysis on early mortality after orthotopic liver transplantation.

AIM: To identify the risk factors relating to early mortality after orthotopic liver transplantation. METHODS: Clinical data of 37 adult patients undergoing liver transplantation were retrospectively collected and divided into two groups: the survived group and the death group (survival time<30 d). The relationship between multivariate risk factors and early mortality after orthotopic liver transplantation were analyzed by stepwise logistic regression. RESULTS: The survival rate was 73%. Early mortality rate was 27%. APACAE III, preoperative serum creatinine level and interoperative bleeding quantity had a significant independent association with early mortality. (R=0.1841, 0.2056 and 0.3738). CONCLUSION: APACHE III,preoperative serum creatinine level and interoperative bleeding quantity are significant risk factors relating to early mortality after orthotopic liver transplantation. To improve the recipient's preoperative critical condition and renal function and to reduce interoperative bleeding quantity could lower the early mortality after orthotopic liver transplantation.
