BACKGROUND/AIMS: The motility change after peroral endoscopic myotomy (POEM) in achalasia is currently focused on lower esophageal sphincter (LES). This study aims to investigate the correlation of motility response between distal and proximal esophagus after POEM. METHODS: A total of 32 achalasia patients who received POEM and high-resolution manometry (HRM) were included for analysis. Eckardt score was used to assess symptom improvement. HRM was applied for studying motility. Main parameters analyzed were (1) LES: resting pressure (restP), 4-second integrated relaxation pressure; (2) esophageal body (EB): contractile integral of distal segment with myotomy (CI-DM) and proximal segment without myotomy (CI-PNM); and (3) upper esophageal sphincter (UES): relaxation pressure (UES-RP). RESULTS: There were 6 type I, 17 type II, and 9 type III achalasia patients included for analysis. (1) Eckardt score, LES tone, CI-DM, CI-PNM and UES-RP were reduced remarkably after POEM (P < 0.001). (2) no significant correlation was noted between LES tone and contractile intergral of EB. (3) a positive linear correlation of CI-DM and CI-PNM changes was detected (P < 0.001). (4) the change of UES-RP was positively correlated with the change of contractile integral of EB (P < 0.001). CONCLUSIONS: Myotomy of the distal esophagus would attenuate proximal EB contraction and assist UES relaxation in achalasia patients after POEM.

OBJECTIVETo evaluate the effect of glycogen on calcium concentration of rabbit donor liver during ischemia-reperfusion period.
METHODSDonor group (n=21) was divided into 3 subgroups randomly: Group A (n=7): fasting for 24 hours before harvesting; Group B (n=7): normal laboratory chew; Group C (n=7): normal laboratory chew plus glucose supplement intravenously. Based on the self-created animal model for ischemia-reperfusion, the levels of glycogen content, ATP level, viability of Ca(2+)ATPase and plasmic free Ca(2+) concentration ([Ca(2+)]i) of liver tissue were measured.
RESULTSBefore cold preservation, there was a significant difference of glycogen content among the three groups at all time points except at the end of rewarming period. ATP level and Ca(2+)ATPase viability were significantly higher in group C than in other two groups. But the plasmic free Ca(2+) concentration was lower in groups with higher glycogen content.
CONCLUSIONSDonor liver with high glycogen content can provide relatively sufficient ATP, maintain better Ca(2+)ATPase viability and prevent plasmic free Ca(2+) concentration overloading. This maybe an important mechanism for glycogen to ameliorate ischemia-reperfusion injury to the donor livers.
