Recent evidence suggested that associating liver partition and portal vein ligation for staged hepatectomy with a partial split could effectively induce the same degree of future liver remnant hypertrophy as a complete split in non-cirrhotic and non-cholestatic livers with better postoperative safety profiles. Our aim was to evaluate if the same phenomenon could be applied to hepatitis-related chronic liver diseases. ⋯ Complete-associating liver partition and portal vein ligation for staged hepatectomy induced more rapid future liver remnant hypertrophy than partial-associating liver partition and portal vein ligation for staged hepatectomy without increased perioperative risk in chronic liver diseases.

Carbohydrate antigen (CA19-9) is a well-established marker to monitor disease status after resection of pancreatic cancer. However, few serum markers have been reported to improve the prognostic ability of postoperative CA19-9, especially in patients with normal postoperative CA19-9. ⋯ The postoperative monitoring of CEA and CA125 provided prognostic significance to the measurement of CA19-9 in pancreatic cancer after resection.

Comparative Study
Identification of primary tumors in patients presenting with metastatic gastroenteropancreatic neuroendocrine tumors.
Patients with gastroenteropancreatic neuroendocrine tumors often present with metastases. Identification of the primary tumor is important for operative management, and therefore we sought to determine our success at identifying primary tumors with diagnostic testing and operative exploration. ⋯ Imaging and endoscopy identified the primary tumor in most patients, and the majority of the others were found at exploration. Preoperative testing facilitated operative planning, allowing for resection of the primary and hepatic debulking in most patients.

Comparative Study
Cost-effectiveness of active surveillance versus hemithyroidectomy for micropapillary thyroid cancer.
The management of low-risk micropapillary thyroid cancer <1 cm in size has come into question, because recent data have shown that nonoperative active surveillance of micropapillary thyroid cancer is a viable alternative to hemithyroidectomy. We conducted a cost-effectiveness analysis to help decide between observation versus operation. ⋯ The cost-effectiveness of hemithyroidectomy is highly dependent on patient disutility associated with active surveillance. In patients who would associate nonoperative management with at least a modest decrement in quality of life, hemithyroidectomy is cost-effective.
