Performing an intracorporeal esophagojejunostomy during laparoscopic-assisted total or proximal gastrectomy is challenging. We developed an ingenious method of overlapping esophagojejunostomy using a linear stapler to avoid stapler-related intraoperative complications. Following lymph node dissection, the esophagus was transected anterior-posteriorly.

The lack of tension at the anastomosis site and the blood flow of the gastric conduit are important to prevent anastomotic leakage in the anastomosis of the esophagogastric conduit. This study reports a gastric conduit stump closure method using Endo GIA™ Radial Reload in end-to-side anastomosis of the esophagogastric conduit, especially focusing on blood flow. A 4-cm conduit was created to ensure an intramural vascular network.

Background: We focused on the lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) and devised an inflammation-combined prognostic index (ICPI) as a prognostic marker of cancer-specific survival (CSS).

Methods: We reviewed the clinicopathological data of 480 patients with gastric cancer undergoing curative laparoscopic gastrectomy between 2009 and 2019. This study examined the significance of LMR, NLR, PLR, and ICPI as cancer-specific prognostic markers.

Background And Objective: Robot-assisted surgery is particularly useful in esophagectomy for esophageal cancer because robotic systems have high-resolution three-dimensional imaging, tremor filtering, and articulated instruments. This review article focuses on the applications and limitations of surgical devices in robot-assisted minimally invasive esophagectomy (RAMIE).

Methods: A narrative search of Medline was performed for articles published using the keywords "robot-assisted esophagectomy", "technique", "postoperative complication", and "short-term outcomes".

Background: Despite advances in surgical techniques, long-term survival after esophagectomy for esophageal cancer remains unacceptably low, and more effective perioperative chemotherapy is expected. However, an important concern regarding the application of postoperative adjuvant chemotherapy is treatment toxicity. We aimed to evaluate the feasibility of adjuvant chemotherapy with S-1 in patients after esophagectomy.

Article Synopsis
  • The study investigates the impact of laparoscopic caudate portal venous ligation combined with transileocolic portal vein embolization (Lap-cPVL/rTIPE) as a preparation for major liver surgery in patients with advanced liver cancer.
  • It was found that this combined approach resulted in significantly greater liver hypertrophy and functional growth compared to embolization alone.
  • Additionally, no severe postoperative liver failures occurred in the Lap-cPVL/rTIPE group, highlighting its safety, while no patient died following surgery.

Background: Portal vein embolization (PVE) is widely used to promote the hypertrophy of a future liver remnant (FLR) and reduce posthepatectomy liver failure. The aim of this study was to evaluate the efficacy of transileocecal portal embolization (TIPE) associated with staging laparoscopy (hybrid lap-TIPE) for a planned hepatectomy in advanced hepatobiliary cancers.

Methods: The hybrid lap-TIPE procedure consisted of staging laparoscopy for complete screening of the abdominal cavity with cytoreductive surgery and subsequent TIPE.

Background/purpose: Few reports have evaluated the differences in the predictive accuracy between the physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) and estimation of physiologic ability and surgical stress (E-PASS) in pancreatic surgery. Thus, we evaluated the accuracy and similarity of POSSUM and E-PASS for the prediction of severe postoperative complications (PCs) after pancreatic surgery.

Methods: We enrolled 343 consecutive patients who underwent pancreatic surgery in our department between April 2006 and September 2017.

Background: An artery-first approach for pancreatic cancer (PC) is challenging to perform laparoscopically and is mainly performed using an open approach. The aims of this study were to assess the safety and feasibility of laparoscopic radical antegrade modular pancreatosplenectomy (RAMPS) with an artery-first approach (L-aRAMPS) as compared with open aRAMPS (O-aRAMPS) in resectable PC using matched-pair analysis.

Methods: Artery-first approach is an early dissection of the superior mesenteric artery (SMA) from behind the pancreas body as the first surgical step.

A 60s-year-old Japanese male underwent curative resection for an advanced adenocarcinoma of the esophagogastric junction(Stage III C), followed by adjuvant chemotherapy.Twenty -one months later, he was admitted to our hospital with a complaint of marked decline in activities of daily living(ADL).The patient was diagnosed with pancytopenia, disseminated intravascular coagulation(DIC), multiple lymph node and bone metastases, and bone marrow carcinomatosis.

Background: Although hemihepatectomy with total caudate lobectomy (hemiHx-tc) is essential for the surgical treatment of hilar cholangiocarcinoma, the advantage of an anterior approach for hemiHx-tc has not been fully discussed technically; the significance of an anterior approach without liver mobilization for preventing infectious complications also remains unknown.

Methods: The liver parenchyma transection-first approach (Hp-first) technique is an early transection of the hepatic parenchyma without mobilization of the liver that utilizes a modified liver-hanging maneuver to avoid damaging the future remnant liver.

Results: Between May 2010 and August 2016, a total of 40 consecutive patients underwent surgery for hilar cholangiocarcinoma.

Background: Incomplete tumor resection with insufficient lymphadenectomy following a pancreaticoduodenectomy (PD) for lower biliary tract cancer results in a dismal outcome. This study aimed to compare the short-term outcomes of PD between total meso-pancreatoduodenum excision (tMPDe) and the conventional procedure for lower biliary tract cancer.

Methods: Patients who underwent PD for lower biliary tract cancer between May 2003 and March 2015 were included in this study.

It is now clear that cancer survival is determined not only by tumor pathology but also by host-related factors, in particular, nutritional status and systemic inflammation. It is desirable that the essential properties of any scale designed or intended to be used for the prediction of survival are simple, convenient, and objective. In this study, we retrospectively reviewed the database of patients who underwent curative surgery for esophageal cancer in our department to evaluate controlling nutritional status (CONUT) and neutrophil-lymphocyte ratio (NLR) as predictors of cancer-specific survival (CSS) after esophagectomy.

Background: Unnecessary intra-abdominal drain insertion must be avoided, but little is known about the value of prophylactic drainage following laparoscopic distal gastrectomy (LDG). In this study, we investigated the significance of prophylactic drain placement after LDG for gastric cancer.

Methods: Seventy-eight consecutive patients with gastric cancer who underwent LDG in our department were retrospectively analyzed.

Background: Previously it has reported that the incidence of internal hernia can be decreased by closing Petersen's defect, but the perfect closure method, in fact, has not been discovered yet. In this study we have developed an easy and reliable method for closing Petersen's defect in the Roux-en-Y reconstruction after a laparoscopic distal gastrectomy.

Materials And Methods: We performed intracorporeal Roux-en-Y reconstruction after laparoscopic distal gastrectomy with antiperistaltic gastrojejunostomy.

The mechanisms of colonization and growth of metastatic liver tumors from colorectal cancers remain obscure. Forty-three resected colorectal metastatic liver tumors with surrounding livers were evaluated for apoptotic index (AI), proliferation index (PI), and immunohistochemical expressions of TGF-beta1. TGF-beta receptor II, Fas, and Fas-ligand.
