Anastomotic tension "Bridging": a risk factor for anastomotic leakage following low anterior resection.

Background: Excessive tension at the anastomosis contributes to anastomotic leakage (AL) in low anterior resection (LAR). However, the specific tension has not been measured. We assessed whether "Bridging," characterized by the proximal colon resembling a suspension bridge above the pelvic floor, is a significant risk factor for AL following LAR for rectal cancer.

Risk Factors for Stoma Outlet Obstruction: Preventing This Complication after Construction of Diverting Ileostomy during Laparoscopic Colorectal Surgery.

Introduction: Bowel obstruction at the outlet of the stoma, also referred to as "stoma outlet obstruction" (SOO), has been noted to be more common after laparoscopic colorectal surgery with diverting ileostomy than after laparotomy. Thus, the aim of this study is to identify the risk factors for SOO and to evaluate the effectiveness of a modified ileostomy procedure for reducing its incidence.

Methods: The medical records of 63 patients who underwent laparoscopic colorectal surgery with diverting ileostomy between January 2014 and July 2021 were retrospectively reviewed.

The impact of standardized methods of hepatic vein reconstruction with an external iliac vein graft.

Background: Liver tumors that invade the hepatic vein are surgically challenging, especially in patients with liver dysfunction. Preservation of as much of the parenchyma as possible is important; thus, when feasible, we perform hepatectomy with hepatic vein reconstruction (HVR) using an external iliac vein (EIV) graft. We conducted a retrospective study to investigate the benefit of HVR and to evaluate our procedure.

Laparoscopic transabdominal preperitoneal repair versus open mesh plug repair for bilateral primary inguinal hernia.

Aim: A few studies comparing laparoscopic and open techniques have reported that open repair with mesh is the optimal operation for unilateral primary hernia. The aim of this study is to compare the outcomes of laparoscopic transabdominal preperitoneal repair (TAPP) versus open mesh plug repair (MP) for bilateral primary inguinal hernia.

Methods: This was a retrospective study of 107 patients with bilateral primary inguinal hernia between January 2008 and December 2016.

The preoperative prognostic nutrition index is a prognostic indicator for survival in elderly gastric cancer patients after gastrectomy: a propensity score-matched analysis.

The incidence of gastric cancer (GC) in elderly patients has increased, and it is important for predicting prognosis for those patients. The prognostic nutrition index (PNI), which is a indicator of nutrition status, is useful for the assessment of prognosis for various cancers. The aim of this propensity score-matched study was to investigate the significance of the PNI for predicting the long-term outcome of GC patients who were 80 years old or older.

The Prognostic Impact of the Lymphocyte-to-Monocyte Ratio in Resected Pancreatic Head Adenocarcinoma.

Objective: Although the prognostic significance of systematic inflammation-based scores, such as the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), and the prognostic nutritional index (PNI), has been explored in pancreatic cancers, few reports have investigated the lymphocyte-to-monocyte ratio (LMR). We aimed to retrospectively investigate the prognostic value of the preoperative LMR in patients with resectable pancreatic head cancer (PHC).

Methods: From 2005 to 2016, 165 patients underwent pancreatoduodenectomy for PHC.

Laparoscopic pancreaticoduodenectomy for remnant pancreatic recurrence after laparoscopic distal pancreatectomy and hepatectomy for greater omentum leiomyosarcoma.

Laparoscopic pancreatic surgery is one of the most difficult procedures, and the adoption of laparoscopic pancreaticoduodenectomy has been limited. The application of laparoscopic surgery has extended to advance cancer, but there have been no reports of laparoscopic pancreaticoduodenectomy after laparoscopic liver resection and distal pancreatectomy. In the present case, a 67-year-old woman was diagnosed with remnant pancreatic recurrence of metastatic greater omentum leiomyosarcoma.

Comparison of end-to-end anastomosis and interposition graft during pancreatoduodenectomy with portal vein reconstruction for pancreatic ductal adenocarcinoma.

Purpose: Many studies report that pancreatoduodenectomy (PD) with portal-superior mesenteric vein resection and reconstruction (PVR) is not a contraindication to extended tumor resection for pancreatic ductal adenocarcinoma. However, the clinical benefit of an interposition graft for PVR still remains controversial.

Methods: Between January 2001 and December 2017, 199 patients with pancreatic cancer underwent PD either with or without PVR, and their medical records were reviewed retrospectively, paying specific attention to the PVR methods and the long-term outcome.

Etiologies and outcomes of emergency surgery for acute abdominal pain: an audit of 1456 cases in a single center.

Purpose: There are few studies that have reported the details of emergency surgery for acute abdominal pain. This study aimed to clarify the etiologies and outcomes of emergency abdominal surgery among patients in different age categories.

Methods: Between January 2014 and December 2016, 1456 patients aged 7 years or older who underwent emergency surgery for acute abdominal pain at our institution were enrolled in this study.

Adverse oncological outcome of surgical site infection after liver resection for colorectal liver metastases.

Purposes: Postoperative complications are associated with poor overall and cancer-specific survival after resection of various types of cancer, including primary colorectal cancer. However, the oncological impact of surgical site infection (SSI) after liver resection for colorectal liver metastases (CLM) is unclear. The aim of this study was to investigate the oncological impact of SSI after liver resection for CLM.

Exploration of serum biomarkers for predicting the response to Inchinkoto (ICKT), a Japanese traditional herbal medicine.

Introduction: In patients with obstructive jaundice, biliary drainage sometimes fails to result in improvement. A pharmaceutical-grade choleretic herbal medicine, Inchinkoto (ICKT), has been proposed to exert auxiliary effects on biliary drainage; however, its effects are variable among patients.

Objectives: The aim of this study is to explore serum biomarkers that are associated with pharmaceutical efficacy of ICKT.

Internal hernia after proximal gastrectomy with jejunal interposition.

Although internal hernia (IH) has been reported after laparoscopic distal or total gastrectomy with Roux-en-Y reconstruction, there are few reports of IH after proximal gastrectomy with jejunal interposition (PG-JI). The aim of this study was to analyze the incidence and clinical features of IH after PG-JI. This study retrospectively reviewed 71 patients who underwent PG-JI for gastric cancer at a single institution between July 2007 and December 2016.

Does the intestinal microenvironment have an impact on the choleretic effect of inchinkoto, a hepatoprotective herbal medicine?

Aim: The choleretic effects of inchinkoto (ICKT), a hepatoprotective herbal medicine, are variable among patients. This study sought to investigate the correlation between the choleretic effects of ICKT and the intestinal microenvironment in patients with biliary obstruction.

Methods: Patients with biliary obstruction who underwent external biliary drainage were enrolled.

Adjuvant hepatic artery infusion chemotherapy after hemihepatectomy for gastric cancer liver metastases.

Background: The most frequent pattern of recurrence is remnant liver after hepatectomy for gastric cancer liver metastases (GLM). The evidence of adjuvant hepatic artery infusion chemotherapy (HAIC) after hepatectomy for GLM is lacking. The aim of this study was to evaluate the efficacy of adjuvant HAIC after hemihepatectomy for GLM.

Clinical Effect of Water-Soluble Contrast Agents for Small Bowel Obstruction in the Virgin Abdomen.

Background: Several studies have investigated the diagnostic and therapeutic role of water-soluble contrast agents (WSCAs) in adhesive small bowel obstruction (SBO). However, the clinical effect of WSCA for SBO without previous intraabdominal operation (i.e.

Bilobar versus unilobar multiple colorectal liver metastases: a propensity score analysis of surgical outcomes and recurrence patterns.

Background: Bilobar multiple colorectal liver metastases (MCLM) are often considered incurable or associated with a poor prognosis even after R0 resection. This study was designed to compare the long-term outcomes and recurrence patterns after one-stage resection in patients with bilobar versus unilobar MCLM.

Methods: The records of patients undergoing parenchymal-sparing intent hepatectomy between 1994 and 2015 were reviewed.

A case of advanced intrahepatic cholangiocarcinoma accidentally, but successfully, treated with capecitabine plus oxaliplatin (CAPOX) therapy combined with bevacizumab: a case report.

Although surgical resection is the only way to cure biliary tract cancer (BTC), most BTCs are unresectable by the time they are diagnosed. Chemotherapy is usually used to treat unresectable BTC, but its impact on survival is small. Here, we report the case of a 70-year-old woman with a locally advanced intrahepatic cholangiocarcinoma that was initially diagnosed as an unresectable liver metastasis from colon cancer that had invaded all of the major hepatic veins.
