Detection of early gastric tube cancers (GTCs) has increased with more detailed surveillance endoscopy using indigo carmine dye following esophagectomy. This retrospective study clarified the clinicopathological features and application of endoscopic submucosal dissection (ESD) for GTCs. Data collected for eight GTCs treated by ESD included clinical and pathological features and outcomes following ESD. Overall, eight GTCs were identified in seven (6.3 %) of 112 patients who underwent esophagectomy and gastric tube reconstruction. Almost all lesions were macroscopically type 0-IIa with mucosal to submucosal invasion, and seven GTCs were successfully resected en bloc by ESD. Submucosal invasion to > 500 microm was observed in one case with associated delayed perforation that was treated conservatively. No local recurrences of GTCs were observed. Detailed surveillance endoscopy using indigo carmine dye appears useful for diagnosing early-stage GTC. Furthermore ESD represents a feasible alternative to conventional endoscopic mucosal resection as a minimally invasive therapy for early-stage GTC.
Background: Hepatectomy is currently recommended as the most reliable treatment for colorectal liver metastases. However, the association between the choice of treatment for recurrence and the timing of recurrence remains controversial. Methods: Two-hundred ninety-five patients who underwent hepatectomy were retrospectively analyzed for the risk factors and the outcomes for early recurrence within 6 months. The remnant liver volumes (RLVs) and laboratory data were measured postoperatively using multidetector computed tomography on days 7 and months 1, 2, and 5 after the operation. Results: Early recurrence developed in 88/295 patients (29.8%). Colorectal cancer lymph node metastasis, synchronous liver metastasis, and multiple liver metastases were independent risk factors for the occurrence of early recurrence (p < 0.001, 0.032, and 0.019, respectively). Patients with early recurrence had a poorer prognosis than did patients who developed later recurrence (p < 0.001). Patients who underwent surgery or other local treatment had better outcomes. The changes in RLV and laboratory data after postoperative month 2 were not significantly different between the 2 groups. Conclusion: Patients with early recurrence within 6 months had a poorer prognosis than did patients who developed later recurrence. However, patients who underwent repeat hepatectomy for recurrence had a better prognosis than did those who underwent other treatments, with good prospects for long-term survival.
The effect of recombinant human soluble thrombomodulin (TM-α) on acute liver failure (ALF) is unclear, and we elucidated the effect of TM-α in lipopolysaccharide (LPS)/d-galactosamine (GalN)-induced ALF in mice. Placebo (saline) or TM-α (100 mg/kg) was administered 1 h after LPS/GalN administration. Survival rates were evaluated for 24 h after LPS/GalN administration. Plasma and liver samples were evaluated 1, 3, and 7 h after LPS/GalN administration. Survival rates were significantly higher in the TM-α-treated group than in the placebo group. A significant augmentation of plasma high-mobility group box 1 protein (HMGB1) was observed 7 h after LPS/GalN administration. In the TM-α-treated mice, plasma HMGB1 was significantly lower than in the placebo group. A significant augmentation of hepatic nuclear factor (NF)-κB p65 was observed in the placebo-treated group, whereas a significant reduction, relative to placebo, was observed in the TM-α-treated group. Hepatic expression of tumor necrosis factor (TNF)-α and myeloperoxidase were significantly increased in the placebo group, and were similarly significantly attenuated in the TM-α-treated group. TM-α treatment also produced a significant attenuation of liver neutrophil accumulation after LPS/GalN administration. Thus, TM-α may become a useful treatment strategy for reducing the symptoms of ALF via the attenuation of LPS/GalN-induced HMGB1 levels.
CHO had no effect on raising the intraoperative core temperature, and no negative impact on the perioperative outcome. CHO prevented the loss of lower limb muscle mass, which may lead to better postoperative recovery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
