Case Presentation: Case 1 involved a 67-year-old female patient diagnosed with endometrial cancer (pT1aN0M0, pStage Ia, grade 1).

Impact of endoscopic ultrasound-guided transmural drainage for postoperative pancreatic fistula after pancreatic surgery.

Objectives: Postoperative pancreatic fistula (POPF) is a major cause of morbidity after pancreatic surgery. Recently, endoscopic ultrasound-guided transmural drainage (EUS-TD) has been widely used to manage pancreatic pseudocysts after acute pancreatitis. Several studies have reported the effectiveness of EUS-TD for POPF, although there is insufficient evidence regarding the performance of EUS-TD for POPF.

Transduodenal ampullectomy for early ampullary cancer: Clinical management, histopathological findings and long-term outcomes at a single center.

Background: Transduodenal ampullectomy has been attempted in ampullary tumors, including early ampullary cancer. However, the indication and extent of transduodenal ampullectomy with curative intent remain controversial. Herein, we address the perioperative and long-term outcomes of patients with early ampullary cancer who underwent transduodenal ampullectomy at a single center.

Three-dimensional simulation of the pancreatic parenchyma, pancreatic duct and vascular arrangement in pancreatic surgery using a deep learning algorithm.

Three-dimensional surgical simulation, already in use for hepatic surgery, can be used in pancreatic surgery. However, some problems still need to be overcome to achieve more precise pancreatic surgical simulation. The present study evaluates the performance of SYNAPSE VINCENT® (version 6.

Optimal Region of Lymph Node Dissection in Distal Pancreatectomy for Left-Sided Pancreatic Cancer Based on Tumor Location.

Background: The optimal lymph node (LN) dissection for left-sided pancreatic cancer based on tumor location has remained unknown. In particular, the efficacy of LN dissection around the common hepatic artery and the celiac axis for distal tumors has not been established. This study was designed to elucidate the frequency and prognostic impact of LN metastasis, focusing on tumor location.

Colloid carcinoma derived from intraductal papillary mucinous neoplasm of the pancreatic head with calcification: A case report and literature review.

Background: Colloid carcinoma derived from intraductal papillary mucinous neoplasm (IPMN) of the pancreatic head with prominent calcification is exceedingly rare. Only a few studies about this entity have been reported in the literature. Therefore, its biological behavior, appropriate treatment modalities, and overall patient prognosis remain largely unclear.

Three-dimensional remnant pancreatic volume ratio indicates postoperative pancreatic exocrine insufficiency in pancreatic cancer patients after distal pancreatectomy.

Background: Pancreatectomy may cause serious pancreatic exocrine insufficiency (PEI), which can lead to some nutritional problems, including new-onset diabetes mellitus (DM) or non-alcoholic fatty liver disease (NAFLD). Recent studies have reported that remnant pancreatic volume (RPV) significantly influences postoperative PEI. However, the specific correlation between RPV and postoperative PEI remains unclear.

Modified Reinforced Staple Closure Technique Decreases Postoperative Pancreatic Fistula After Distal Pancreatectomy.

Postoperative pancreatic fistula (POPF) is a serious complication that can occur following distal pancreatectomy (DP). Recent studies demonstrated that the use of reinforced staplers with bioabsorbable mesh significantly reduced the incidence of POPF, although the safety and efficacy of this approach remain controversial. Therefore, we originally developed a modified closure technique that combines the use of a reinforced stapler with bioabsorbable mesh with suture closure of the main pancreatic duct.

Pathological complete response after preoperative chemotherapy including FOLFOX plus bevacizumab for locally advanced rectal cancer: A case report and literature review.

Background: In Japan, the significance and efficacy of preoperative chemotherapy alone for locally advanced rectal cancer remain controversial. This case report presents the apparent effectiveness of preoperative FOLFOX plus bevacizumab as shown by pathological complete response (pCR). Additionally, we review the relevant literature and discuss the clinical management of locally advanced rectal cancer with preoperative chemotherapy.

Remnant pancreatic volume as an indicator of poor prognosis in pancreatic cancer patients after resection.

Background: Remnant pancreatic volume (RPV) is a well-known marker for short-term outcomes in pancreatic cancer patients after resection. However, in terms of the long-term outcomes, the significance of the RPV value remains unclear. Here, we address whether the RPV value is a predictor of the long-term outcomes in pancreatic cancer patients after resection by comparing various cancer-, patient-, and surgery-related prognostic factors and systemic inflammatory response markers in a retrospective cohort.

Three-Dimensional Remnant Pancreatic Volumetry Predicts Postoperative Pancreatic Fistula in Pancreatic Cancer Patients after Pancreaticoduodenectomy.

Background: Postoperative pancreatic fistula (POPF) is a serious complication that can occur following pancreaticoduodenectomy (PD). Recent studies suggest that remnant pancreatic volume (RPV) values from preoperative multidetector computed tomography (MDCT) are highly predictive of POPF. We performed three-dimensional (3D) surgical simulation of PD including RPV measurements.

Three-dimensional surgical simulation of the bile duct and vascular arrangement in pancreatoduodenectomy: A retrospective cohort study.

Background/aims: We evaluated the usefulness of three-dimensional (3D) images for pancreatoduodenectomy (PD), including the classification of the bile duct and vascular arrangement, i.e., hepatic artery, inferior mesenteric vein (IMV) and left gastric vein (LGV).

Gastric adenocarcinoma of fundic gland mucosa type localized in the submucosa: A case report.

Rationale: Gastric adenocarcinoma of fundic gland type (GA-FG) is a new histological type of gastric cancer manifesting with differentiation into a fundic gland. Furthermore, gastric adenocarcinoma of fundic gland mucosa type (GA-FGM) is a tumor that shows differentiation into not only a fundic gland but also foveolar epithelium and a mucous gland. These tumors tend to invade the submucosal layer.

Impact of Three-Dimensional Surgical Simulation on Pancreatic Surgery.

Background/aims: Anatomical variations are frequently encountered during hepato-biliary-pancreatic surgeries, requiring surgeons to have a precise understanding of the surgical anatomy in order to perform a safe surgery. We evaluated the impact of novel three-dimensional (3D) surgical simulation on pancreatic surgeries to enhance surgical residents' understanding.

Methodology: Between January 2013 and May 2014, 61 preoperative 3D surgical simulations were performed.

The neutrophil-to-lymphocyte ratio (NLR) predicts short-term and long-term outcomes in gastric cancer patients.

Background: The preoperative neutrophil-to-lymphocyte ratio (NLR) is a well-known prognostic marker for gastric cancer patients. However, the utility of the NLR in predicting short-term outcomes in gastric cancer patients remains unclear. Here, we investigated whether the preoperative NLR is a predictor of short-term outcomes in gastric cancer patients.

The impact of three-dimensional reconstruction on laparoscopic-assisted surgery for right-sided colon cancer.

Introduction: During laparoscopic-assisted colorectal surgery (LACS) for right-sided colon cancer patients, we performed three-dimensional (3D) surgical simulation to investigate vascular anatomy, including the ileocolic artery (ICA), right colic artery (RCA) and superior mesenteric vein (SMV).

Aim: We also used 3D imaging to examine the shortest distance from the root of the ileocolic vein (ICV) to the gastrocolic trunk (GCT).

Material And Methods: We analyzed 46 right-sided colon cancer patients who underwent 3D-simulated LACS.

The Impact of Laparoscopic-assisted Colorectal Surgery Using 3-dimensional Reconstruction for Highly Obese Patients With Colorectal Cancer.

Objectives: During laparoscopic-assisted colorectal surgery (LACS), precise recognition of the anatomic variations and relationships among tumor and vessels is required. However, in highly obese patients, it is more difficult to grasp the surgical anatomy due to the presence of dense mesenteric fat tissue. We utilized a 3-dimensional (3D) reconstructed image for preoperative simulation and intraoperative navigation for LACS.
