Evaluation after implementation of chemical bowel preparation for surgical site infections in elective colorectal cancer surgery and role of antimicrobial stewardship pharmacist: Retrospective cohort study.

Background: We evaluated the predictive factors for surgical site infections (SSIs) in elective colorectal cancer surgery and the role of antimicrobial stewardship (AS) pharmacists in modifying the clinical pathway.

Main Body: Between February 2017 and January 2022, 414 elective colorectal cancer surgeries were performed. The results of multivariate analysis by SSI incidence were adjusted odds ratio (aOR): 0.

[Three Cases of No. 16 Lymph Node Metastasis-Positive Gastric Cancer Successfully Treated with Chemotherapy and Para-Aortic Lymph Node Dissection].

Chemotherapy is standard treatment for Stage Ⅳ advanced gastric cancer(AGC)positive for No. 16 lymph node(LN) metastasis, but the significance of conversion surgery remains unclear. S-1 plus CDDP(SP), primary lesion resection+ para-aortic LN dissection(PAND), and postoperative recurrence-free survival are reported.

Elective laparoscopic colectomy in a patient 3 weeks after coronavirus disease 2019 infection: a case report.

Background: According to previous reports, surgery is not recommended until at least 4 weeks after the symptoms of coronavirus disease 2019 resolve. However, strong evidence has not been established regarding the optimal timing and preoperative examination for elective laparoscopic colectomy for colorectal cancer in individuals with a previous coronavirus disease 2019 infection.

Case Presentation: A 63-year-old Asian man underwent elective laparoscopic colectomy for sigmoid colon cancer 3 weeks after asymptomatic coronavirus disease 2019.

Granulocyte-colony stimulating factor-producing gallbladder carcinoma-include analysis all case reports: A case report.

Introduction: It is extremely rare for gallbladder carcinoma to produce granulocyte-colony stimulating factor (G-CSF) and such tumors have a poor prognosis.

Presentation Of Case: A 67-year-old man was admitted with continuous fever. Laboratory tests showed a leukocyte count of 27,980/μL, serum C-reactive protein (CRP) of 9.

[A case of advanced gastric cancer with tumor embolus in the portal vein and liver metastasis responding to S-1 plus cisplatin chemotherapy].

A 67-year-old woman presented with anemia. Computed tomography and upper gastrointestinal endoscopy revealed a primary gastric cancer with tumor embolus in the portal vein, liver metastasis, lymph node metastasis, and pancreatic involvement. Because curative surgery was deemed impossible, we started chemotherapy using S-1 (120 mg/m(2)/day for 3 weeks, followed by discontinuation for 2 weeks) plus cisplatin (80 mg/m(2)/day on days 1 and 8).

Use of 3-dimensional computed hepatic venous visualization for graft outflow venoplasty in adult left living-donor liver transplant.

Objectives: A surgeon must be aware of hepatic vascular variations to safely perform living-donor liver transplant. The ramification patterns of the hepatic veins with tributaries for left lobe graft outflow venoplasty should be evaluated preoperatively with 3-dimensional computed tomography of the donor.

Materials And Methods: Twenty-four potential donors were examined between October 1999 and July 2006 for living-donor liver transplant using the left lobe.

Transumbilical portal venous catheterization: a useful adjunct in left lobe living donor liver transplantation.

To improve the processes used for perfusion of the explanted graft and measuring the portal venous pressure (PVP) in adult living donor transplantation (LDLT), we performed transumbilical portal venous catheterization (TPVC) to reopen the umbilical vein and insert the catheter for seven adult patients undergoing left lobe LDLT. There were no major complications as a result of this procedure. This procedure prior to implanting the graft was derived from our experience and is a classic diagnostic technique used during liver surgery.

Graft size and donor age are independent factors for graft loss in adult-to-adult living-donor liver transplantation using the left liver.

Background/purpose: Graft survival is affected by various factors, such as preoperative state and the ages of the recipient and donor, as well as graft size. The objective of this study was to analyze the risk factors for graft survival.

Methods: From September 1997 to July 2005, 24 patients who had undergone living-donor liver transplantation (LDLT) were retrospectively analyzed.

Sectionectomy is suitable for patients with T2 hepatocellular carcinoma according to the modified international union against cancer TNM Classification.

Background/aims: The effectiveness of systematized hepatectomy in the modified International Union Against Cancer (UICC) staging classification for hepatocellular carcinoma (HCC) has not been clarified in detail.

Methods: We retrospectively studied 406 patients with UICC T1 HCC and 124 patients with T2 HCC who underwent initial curative hepatectomy from 1994 through 2003. Outcomes after sectionectomy or larger resection and segmentectomy or smaller resection for patients with T1 HCC and T2 HCC were examined.

Hepatopancreatoduodenectomy could be allowed for patients with advanced intrahepatic cholangiocarcinoma.

Background/aims: Patients with advanced intrahepatic cholangiocarcinoma (ICC) have a poor outcome even if they undergo extended radical surgery. Hepatopancreatoduodenectomy (HPD; hepatectomy with pancreatoduodenectomy) for ICCs may be expected to provide a favorable outcome if curative resection is reasonable and patients can tolerate the radical major procedure.

Methodology: Between January 1981 and March 2002, 152 hepatic resections were performed for ICC.

Liver metastases with massive portal venous tumor thrombi from colorectal cancer: can be treated by surgical resection?

Background/aims: The surgical treatments for liver metastases from colorectal cancer with massive portal venous tumor thrombi were evaluated.

Methodology: Five patients, among the 142 patients who underwent hepatic resection for liver metastases from colorectal cancer from 1989 to 1998, were included in this study. The tumor thrombi in the main portal vein were removed by the following procedures; (1) the circumferential incision of the first branch of the portal vein and removal of the exposed tumor thrombi with ring forceps and suction, (2) temporary clamping of the distal end, (3) dilatation of the round ligament and the venous cannula was inserted into the umbilical portion, (4) washing out of the residual tumor thrombi, (5) declamping of the distal end and closing suture of the cut end of the portal branch.

Detection of hepatocellular carcinoma capsule by contrast-enhanced ultrasound using Levovist: correlations with pathological findings.

Purpose: To determine the most appropriate therapy for each hepatocellular carcinoma (HCC) nodule, it is important to ascertain whether the tumor has a capsule. The aim of this study was to investigate the diagnostic potential of contrast-enhanced ultrasound (CEUS) in HCC capsule detection by comparing ultrasound findings with histological results from operative specimens.

Methods: Thirty-six HCC nodules (all smaller than 5 cm) from 36 patients who had undergone hepatectomy were examined by CEUS using Levovist with agent detection imaging.

Step classification is useful for the determination of indications for systematized hepatectomy in hepatocellular carcinoma.

Background/purpose: The effectiveness of systematized hepatectomy with transection of Glisson's pedicle at the hepatic hilus has not been clarified in detail in relation to previous staging systems. Outcomes after systematized hepatectomy in patients with hepatocellular carcinoma (HCC) were examined in relation to our new staging system.

Methods: We retrospectively studied 955 patients with HCC who underwent hepatectomy from 1989 through 2002.

Histopathologically-diagnosed splenic metastasis in a hepatocellular carcinoma case with adrenal metastasis.

We encountered a patient with hepatocellular carcinoma (HCC), with adrenal gland metastasis, in whom splenic metastasis was diagnosed histopathologically. A 59-year-old man visited our hospital in May 2001 with chief complaints of abdominal distension and pretibial pitting edema. Multiple HCCs associated with HCV-positive liver cirrhosis were detected.

Intrahepatic cholangiocarcinoma diagnosed preoperatively as hepatocellular carcinoma.

Background: Some cases of mass-forming intrahepatic cholangiocarcinoma (ICC) are diagnosed as hepatocellular carcinoma (HCC) based on preoperative imaging and clinical findings. We investigated the backgrounds of such cases.

Methods: Sixty-seven patients with mass-forming ICC underwent surgery from 1980 to 2002.

Histopathologic differentiation of the main nodule determines outcome after hepatic resection for synchronous multicentric hepatocellular carcinomas.

Background/aims: Clinicopathological features and outcome after surgery in patients with synchronous multicentric hepatocellular carcinoma were examined in relation to the histopathological grade of differentiation of the main nodule.

Methodology: Two hundred and sixty-five patients with synchronous multicentric hepatocellular carcinoma (total, 683 nodules) who had undergone curative hepatectomy from 1988 through 1999 were studied retrospectively. In multicentric occurrences of hepatocellular carcinoma, the tumor with the largest dimension was defined as the main nodule, and the others as accessory nodules.

Favorable surgical outcomes in patients with early hepatocellular carcinoma.

Background: Early hepatocellular carcinoma (HCC) is defined as well-differentiated HCC with an obscure tumor margin in the classification of the Liver Cancer Study Group of Japan. However, the surgical outcomes in patients with early HCC have not yet been clarified.

Methods: From 1985 to 1994, 186 patients with HCC 2 cm or less in greatest dimension underwent curative hepatectomy.

Bleeding during hepatectomy can be reduced by clamping the inferior vena cava below the liver.

Background: Control of blood loss is a crucial problem during hepatectomy. Bleeding from the inflow system can be controlled by the Pringle maneuver or selective vascular occlusion. Bleeding from the outflow system is closely related to central venous pressure (CVP).
