Objectives: To evaluate the effects of postoperative pancreatic enzyme replacement therapy on fat digestion and absorption in patients following initial total pancreatectomy.

Methods: Data were retrospectively collected from patients who underwent initial total pancreatectomy at our department between 2012 and 2020. Fat digestion, absorption functions, serum nutritional markers, HbA1c levels, and hepatic steatosis before and after the initial total pancreatectomy were evaluated.

Purpose: Pancreatic ductal adenocarcinoma (PDAC) patients with normal carbohydrate antigen (CA) 19-9 levels can have early-stage cancer or advanced cancer without elevation of CA19-9 level; estimating their malignant potential is difficult. This study investigated the clinical utility of the combined use of preoperative CA 19-9 and Duke pancreatic monoclonal antigen type 2 (DUPAN-2) levels in patients with PDAC.

Methods: Patients who underwent curative-intent surgery for PDAC between November 2005 and December 2021 were investigated.

Purpose: To elucidate the clinical significance of peritoneal washing cytology (PWC) in patients with resectable biliary tract cancer (BTC).

Methods: Clinical data of patients with BTC, who received PWC at curative intent surgery from March 2009 to December 2021, were retrospectively analyzed. Eligible patients were stratified into two groups according to positive or negative PWC.

Background/purpose: This study reports the long-term results of a phase II trial evaluating the clinical efficacy of neoadjuvant gemcitabine, nab-paclitaxel, and S1 (GAS) in borderline resectable pancreatic cancer with arterial contact (BRPC-A).

Methods: A multicenter, single-arm, phase II trial was conducted. Patients received six cycles of GAS and patients without progressive disease were intended for R0 resection.

Purpose: This study aimed to elucidate the difficulty of adjuvant chemotherapy administration in patients with biliary tract carcinoma (BTC).

Methods: Clinical data of patients with BTC who underwent curative-intent surgery were retrospectively analyzed. The eligible patients were stratified into two groups according to the presence or absence of adjuvant chemotherapy administration (adjuvant and non-adjuvant groups), and the clinicopathological features were compared between the two groups.

This study aimed to evaluate the optimal extent of lymphadenectomy in patients with nonfunctioning pancreatic neuroendocrine neoplasms. We retrospectively analyzed the clinicopathological data of patients with nonfunctioning pancreatic neuroendocrine neoplasms who underwent surgical resection. We investigated the frequency of metastases at each lymph node station according to tumor location and analyzed the factors contributing to poor overall survival (OS) and disease-free survival (DFS).

Cancer cell proliferation is affected by post-translational modifications of tubulin. Especially, overexpression or depletion of enzymes for modifications on the tubulin C-terminal region perturbs dynamic instability of the spindle body. Those modifications include processing of C-terminal amino acids of α-tubulin; detyrosination, and a removal of penultimate glutamic acid (Δ2).

Purpose: To elucidate prognostic factors for post-recurrence survival in patients with pancreatic ductal adenocarcinoma (PDAC).

Methods: Patients who underwent curative-intent surgery for PDAC between January 2014 and May 2020 were identified. Among them, patients who had postoperative recurrences and received chemotherapy were retrospectively investigated.

Falciform ligament hernia is a very rare internal hernia and is difficult to diagnose before surgery. We report a case of falciform ligament hernia with a specific symptom and image findings, which led to an accurate diagnosis and subsequent laparoscopic surgery. A 15-year-old adolescent boy with no previous medical history showed epigastric pain and was referred to our hospital.

A 51-year-old male underwent total gastrectomy for esophagogastric junction cancer(T3N0M0, Stage ⅡA). He was diagnosed with an alpha-fetoprotein(AFP) producing tumor and hepatoid adenocarcinoma. One month after radical surgery, computed tomography(CT) showed lung metastasis, and the patient's serum AFP level was high.

A 72-year-old woman with a sigmoid colon cancer and a synchronous colorectal liver metastasis (CRLM), which involved the right hepatic vein (RHV) and the inferior vena cava (IVC), was referred to our hospital. The metastatic lesion was diagnosed as initially unresectable because of its invasion into the confluence of the RHV and IVC. After she had undergone laparoscopic sigmoidectomy for the original tumor, she consequently had 3 courses of modified 5-fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6) plus cetuximab.
