AIM: To compare the outcomes of hand-sewn(HS) and linearly stapled(LS) esophagogastric anastomosis for esophageal ***: Before beginning this study, a rigorous protocol was established according to the recommendations of the Cochrane Collaboration. Databases and references were searched for all randomizedcontrolled trials and comparative clinical studies that compared LS with HS esophagogastric anastomosis for esophageal cancer. The primary outcomes compared were anastomotic leak and stricture. Subgroup analyses were performed according to site of ***: Fifteen studies were used, comprising 3203 patients(n = 2027 LS and 1176 HS). Primary outcome analysis revealed a significant decrease in anastomotic leakage(RR = 0.51, 95%CI: 0.41-0.65; P < 0.00001) a s s o c i a t e d w i t h L S a n a s t o m o s i s. A s i g n i f i c a n t l y reduced rate of anastomotic stricture associated with LS was also found(RR = 0.56, 95%CI: 0.49-0.64; P < 0.00001). A subgroup analysis according to the site of anastomosis revealed a significantly reduced rate of anastomotic stricture(P < 0.00001). Although there was no significant difference in the decrease in thoracic anastomotic leakage, there was a significant decrease in cervical anastomotic leakage associated with LS(P < 0.00001).CONCLUSION: This meta-analysis indicates that the LS technique contributes to a reduced rate of leakage and stricture compared with the HS method.

Hamamatsu R1924A is one of the most widely used photomultiplier tubes(PMTs) in nuclear *** the active base suitable for R1924A is still not available in market, an active base is designed for Hamamatsu R1924A PMT, and the test results at high counting rates are presented. The active bases with two different sets of resistor chains were tested and compared by a frequency-controlled green straw hat LED light. A stable signal output up to 100 kHz is achieved using frequency-controlled LED pulsed light. The temperature of bases, which reflects the power consumption and is crucial for applications in vacuum, is also monitored with the same LED pulsed light. The temperature of the active base with smaller resistances reaches about twice of that of the active base with larger resistances in the resistor chain. For the applications in vacuum, the active base with resistance between the two sets of resistor chains may be preferable.
