Preoperative chemotherapy containing oxaliplatin (FOLFOX) or irinotecan (FOLFIRI) causes histological liver injury and increases postoperative morbidity and mortality in patients with colorectal liver metastasis (CRLM). However, information on the aggravation of liver function and its reversibility is scarce. A total of 55 patients who underwent a(More)
BACKGROUND The aim of this study was to evaluate whether 3-dimensional (3D) simulation software is applicable to and useful for anatomic liver segmentectomy and subsegmentectomy. METHODS A prospective study of 83 consecutive patients who underwent anatomic segmentectomy or subsegmentectomy using the puncture method was performed. All patients underwent 3D(More)
Enhanced recovery programs (ERPs) have been developed in various surgical fields and have been shown to accelerate postoperative recovery without increasing the incidence of adverse events. Whether ERP can be safely applied to patients undergoing complex liver surgery with a risk of liver failure remains unclear. We created an ERP by rearranging our(More)
To examine mechanisms that might be related to biliary pancreatitis, we examined the effects of pancreatic duct ligation (PDL) with pancreatic stimulation in vivo. PDL alone caused no increase in pancreatic levels of trypsinogen activation peptide (TAP), trypsin, or chymotrypsin and did not initiate pancreatitis. Although bombesin caused zymogen activation(More)
Associating liver partition and portal vein ligation (ALPPS) is introduced as a modified two-staged hepatectomy for advanced liver malignancies, which requires extended hepatectomy with very small future remnant liver volume. It is characterized by rapid and large growth of future remnant liver and potential of widening the indication of curative resection(More)
The aim of the study is to evaluate the prognostic impact of the extent of submillimeter or zero surgical margin (SubMM) area among the patients who underwent liver resection for colorectal liver metastases (CRLM).The influence of suboptimal margin width of <1 mm on long-term outcome is unclear.A total of 423 liver resections for CRLM were performed at(More)
Total liver volume (TLV) empirically changes after aggressive preoperative chemotherapy for colorectal liver metastases (CLM). However, the actual degree of changes in normal liver parenchyma and its clinical relevance remain unclear. Morphometric data of 110 patients who underwent initial hepatectomy after preoperative chemotherapy were reviewed. TLVs(More)
OBJECTIVE The aim of the study was to explore the mechanism by which trypsinogen becomes activated during acute pancreatitis. METHODS Given the ability of cholecystokinin (CCK) to induce pancreatitis in vivo, the effects of high-dose CCK on preparations of isolated pancreatic acini were examined using immunofluorescence techniques for the detection of(More)
BACKGROUND Carcinoembryonic antigen (CEA) is a tumor marker used widely for detecting the recurrence and predicting the prognosis of colorectal cancer. This study investigates the possibility of serial measurement of serum CEA in several weeks after liver resection for colorectal liver metastases (CRLM) in detecting earlier detection of recurrence.
