Purpose: Unexpected death occurred in an unexpectedly high proportion of advanced cancer patients in the acute palliative care unit (APCU) setting and associated with fewer signs of impending death. Recognition of patients at high risk of approaching death, especially immediately after admitting APCU among clinicians, can improve the end-of-life trajectory. Our objective was accurate prognostication within a few days of admission.

We report a case of advanced gastric cancer with pyloric stenosis, in which a curative resection was performed following gastrojejunostomy and S-1 based chemotherapy. A 46-year-old female presenting with vomiting was diagnosed with unresectable gastric cancer with pyloric stenosis after a detailed examination. She underwent laparotomy, which revealed a T4 tumor invading the pancreas head and involving the gallbladder.

Intraperitoneal cyst occurring in the lesser omentum is extremely rare entity. Because of the absence of abdominal symptoms, omental cyst is occasionally found accidentally in imaging examination performed during health screening. We experienced a case of cystic lymphangioma that occurred in the lesser omentum, which was successfully resected under complete laparoscopic procedure.

Thrombocytopenia is a frequent finding following living donor hepatectomy. It appears more pronounced in right graft donors than in left graft donors. This study analyzed postoperative thrombocytopenia in 20 living liver donors and examined the change of endogenous thrombopoietin (TPO) in its recovery.

Liver regeneration in living-donor liver transplantation is summarized from the authors' data. In donors, liver function tests recovered to within the normal range 2 weeks after surgery regardless of graft type. At 2 weeks, the volumetric recovery of the remnant liver was 65% and 80% of the original volume in right and left lobe donors, respectively.

Article Synopsis
  • Assessment of gastrointestinal stromal tumors (GISTs) involves measuring maximum tumor size, mitotic index, and the Ki-67 labeling index, which indicates cell growth, with a Ki-67 value of 10% or higher suggesting worse prognosis.
  • A study analyzed factors from 15 patients who had gastric stromal tumors, finding significant differences in tumor size, mitotic index, and Ki-67 values between patients with metastasis/recurrence and benign groups.
  • The findings highlight that these indices are valuable for evaluating malignancy in gastric stromal tumors, while surgical removal may not be enough for patients with widespread metastasis.
