Predictors of successful hepatic resection: prognostic usefulness of hepatic asialoglycoprotein receptor analysis.
To test the clinical usefulness of hepatic asialogycoprotein receptor analysis in liver surgery, we have conducted univariate and multivariate analysis for the detection of cirrhotic patients and prediction of morbidity after hepatic resection. Liver scintigraphy using technetium 99m-labeled asialoglycoprotein analog (TcGSA), ICG test, and CT hepatic volumetry were undertaken in 158 surgical patients including 111 who underwent hepatic resection. Hepatic functional parameters including Child-Pugh score, indocyanine green retention at 15 minutes (ICG-R15), clearance index (HH15), receptor index (LHL15), receptor concentration ([R]0), total hepatic receptor amount (R0) and hepatic parenchymal volume (HPV) were compared among patients with normal, cirrhotic, and non-cirrhotic damaged liver. ⋯ In conclusion, combining the ASGP-R concentration ([R]0) and the Child-Pugh score best detected liver cirrhosis in surgical candidates. Cirrhotic patients and patients with a low R0-remnant are at higher risk for postoperative liver failure. The present study confirms the usefulness of hepatic asialogycoprotein receptor analysis in liver surgery.

Randomized Controlled Trial Comparative Study Clinical TrialPredictive value of blood flow in the gastric tube in anastomotic insufficiency after thoracic esophagectomy.
Anastomotic insufficiency is considered to be one of the most serious complications associated with esophageal reconstruction. The purposes of this study were to identify (1) the relationship between anastomotic insufficiency and tissue blood flow (TBF) in the gastric tube in the perioperative period, and (2) the effects of intravenous prostaglandin E1 (PGE1) on TBF in the gastric tube. The study group consisted of 44 patients who were to undergo esophagectomy for esophageal cancer. ⋯ The TBF of three-field lymph node dissection and reconstruction of the retrosternal route group (n = 21) was poorer than that of the two-field lymph-node dissection and reconstruction of the posterior mediastinal route group (n = 23). The TBF in the gastric tube after esophagectomy may be a predictor of anastomotic insufficiency. However, PGE1 treatment in the intraoperative period alone is not effective in preventing anastomotic insufficiency.
