Background/objectives: This study aimed to evaluate the effect of preoperative immunonutrition on the composition of fecal microbiota following a colon cancer surgery.

Materials/methods: This study was a secondary analysis of a randomized controlled trial assessing the impact of preoperative immunonutrition on the postoperative outcomes of colon cancer surgery. Patients with primary colon cancer were enrolled and randomly assigned to receive additional preoperative immunonutrition or a normal diet alone.

Purpose: The relationship between microsatellite instability (MSI) and tumor response after neoadjuvant chemoradiotherapy (nCRT) in rectal cancer remains unclear. The present study aimed to evaluate the association between MSI and tumor response to nCRT in rectal cancer treatment.

Methods: Patients with rectal cancer from 2 tertiary hospitals who underwent nCRT, followed by radical surgery, were included.

Purpose: Some studies have suggested that circumferential tumor location (CTL) of rectal cancer may affect oncological outcomes. However, studies after preoperative chemoradiotherapy (CRT) are rare. This study aimed to evaluate the impact of CTL on oncologic outcomes of patients with mid to low rectal cancer who received preoperative CRT.

Introduction: Proper handling and firing of the circular stapler are important for secure anastomosis in rectal cancer surgery. This study aimed to investigate the association between the first assistant and anastomotic leakage (AL) after rectal cancer surgery with double-stapling anastomosis.

Methods: Patients with primary rectal cancer who underwent low anterior resection with double-stapling anastomosis between January 2015 and September 2019 were included.

Introduction: Bile peritonitis is one of the rare complications that can occur after cholecystectomy or hepatectomy. It is associated with high mortality, prolonged hospital stay, and increased cost. We herein report 2 cases of bile leakage as a postoperative complication of right hemicolectomy.

Objective: This study aimed to assess the impact of preoperative immunonutrition on the outcomes of colon cancer surgery.

Background: Although current guidelines recommend that immunonutrition should be prescribed for malnourished patients before major gastrointestinal surgery, the benefit of preoperative immunonutrition remains debatable.

Methods: Between April 2019 and October 2020, 176 patients with primary colon cancer were enrolled and randomly assigned (1:1) to receive preoperative immunonutrition plus a normal diet (n = 88) or a normal diet alone (n = 88).

Purpose: The prognosis of pathological T2N0 colon cancer has not been adequately investigated. This study aimed to determine the prognostic factors for pathological T2N0 colon cancer by comparing it with those for pathological T3N0 colon cancer.

Methods: We retrospectively reviewed patients with primary colon cancer who underwent curative resection between January 2007 and December 2015 and included 889 patients with postoperative pathological T2-3N0M0 disease.

Aim: The optimal surgical method for cancer of the mid-transverse colon has not been well established. The present study aimed to explore the distribution of lymph node metastasis and compare the outcomes of extended and transverse colectomies for cancer of the mid-transverse colon.

Methods: We retrospectively analysed the data of patients with cancer of the mid-transverse colon treated with either an extended hemicolectomy (right or left) or a transverse colectomy.

Background: Very few studies have been conducted on the treatment strategy for enlarged paraaortic lymph nodes (PALNs) incidentally detected during surgery. The purpose of this study was to investigate the benefit of lymph node dissection in patients with incidentally detected enlarged PALNs.

Methods: We retrospectively reviewed patients with left colon and rectal cancer who underwent surgical resection with PALN dissection between January 2010 and December 2018.

Background And Aim: The improvements in surgical technique and perioperative management in the recent decades may warrant revisit for survival outcomes and prognostic factors after liver resection for hepatocellular carcinoma (HCC). This study aimed to analyze the survival outcomes after liver resection for HCC for a consecutive cohort of 1002 patients.

Methods: This study was performed by analyzing the clinicopathological and follow-up data of 1002 consecutive patients who underwent liver resection for HCC from April 2001 to December 2013.

Aim: To investigate the impact of high-dose hepatitis B immunoglobulin (HBIG) on hepatocellular carcinoma (HCC) and hepatitis B virus (HBV) recurrence and overall survival after living donor liver transplantation (LDLT).

Methods: We investigated 168 patients who underwent LDLT due to HCC, and who were HBV-DNA/hepatitis B e antigen (HBeAg) -positive, from January 2008 to December 2013. After assessing whether the patients met the Milan criteria, they were assigned to the low-dose HBIG group and high-dose HBIG group.

Purpose: The purpose of this study was to review the daily practice of inferior vena cava filters (IVCFs) in a tertiary referral center in Korea and to reveal the retrieval rate and the methods for improving it.

Materials And Methods: Through the electronic medical record system, a retrospective review was performed on 115 consecutive patients who underwent placement of retrievable IVCFs between February 2000 and January 2011 in Seoul National University Hospital.

Results: IVCF placement was done in 115 cases (113 patients).
