To investigate the effect of High-Frequency Electric Welding (HFEW) on intestinal tissue healing, we performed end-to-end anastomosis experiments in New Zealand rabbits. Within one week post-surgery, animals exhibited normal vital signs, replaced necrotic tissue with healthy collagen, and showed improved tissue strength while inflammation decreased. By day 60, tissue pathology and function fully recovered, resembling normal tissue.

Objective: To describe an exploratory scoring instrument correlating the Delphi consensus on low anterior resection syndrome with functional and quality-of-life scores following intersphincteric resection for ultralow rectal cancer.
Design: This was a prospective pilot study.
Aim: Sphincter-sparing surgery can be achieved in most cases of low rectal cancer with the development of intersphincteric resection. However, abdominoperineal resection is still inevitable for patients with tumours located below the dentate line. To address this, we have developed a procedure called conformal sphincteric resection (CSR) in which the corresponding part of the subcutaneous portion of the external anal sphincter and the perianal skin on the tumour side is removed to achieve a safe distal resection margin and lateral resection margin while the dentate line and the internal anal sphincter on the tumour-free side are preserved as much as possible, to achieve sphincter preservation without compromising oncological safety and functional acceptability, and to render tumour location no longer a contraindication for sphincter-sparing surgery.

Material And Methods: A total of 192 CRC patients (123 men and 69 women) who underwent radical resection participated in this study.
Purpose: Colorectal cancer (CRC) stem cells are tumorigenic, capable of self-renewal, and resistant to therapy. Although the expression pattern and functions of micro RNA (miR)-194 in CRC cells have been widely investigated, little is known about its role in CRC stem cells. Therefore, the aim of this study was to investigate the potential role of miR-194 in CRC stem cells.

The liver is the most common location of CRC metastases, which are the main causes of CRC-related death. However, the mechanisms underlying metastasis of CRC to the liver have not been characterized, resulting in therapeutic challenges.

In this study, we aimed to protect nerve function in such scenarios by performing intraoperative monitoring of pelvic autonomic nerves (IMPAN).
Patients And Methods: We retrospectively investigated a series of 87 patients undergoing laparoscopic low anterior resection of rectal cancer.
Background/aim: Preventive ileostomy is frequently constructed to minimizethe consequences of anastomotic leakage after resection of rectal cancer. There is no consensus regarding the best timing for temporary stoma closure after proctectomy for rectal cancer. This retrospective study sought to determine whether the timing of stoma closure influenced postoperative outcomes.

Methods: We retrospectively reviewed 93 cases of BM from CRC in our hospital. Patient demographics, neurologic symptoms, and location and number of BMs were recorded.
Background: This study was performed to compare the clinical safety and outcomes of laparoscopic versus open surgery for primary tumors in patients with stage IV colorectal cancer.
Methods: Pertinent studies were selected from the MEDLINE, EMBASE, and Cochrane Library databases; references from published articles; and reviews. Both prospective and retrospective studies were included for the meta-analysis.
Objective: To compare the clinical safety and outcomes of early laparoscopic cholecystectomy versus delayed laparoscopic cholecystectomy for acute cholecystitis.
Methods: Pertinent studies were selected from the Medline, EMBASE, and Cochrane library databases, references from published articles, and reviews. Seven randomized controlled trials (early laparoscopic cholecystectomy versus delayed laparoscopic cholecystectomy) were selected.
As an emerging therapeutic approach, adoptive T cell therapy shown promise in advanced solid malignancies. The results obtained in patients with metastatic melanoma and kidney cancer are encouraging because of the visible clinical benefits and limited adverse effects. Recently, the genetically-modified T cells expressing specific T cell receptors or chimeric antigen receptors are just now entering the clinical arena and show great potential for high avidity to tumor-associated antigens and long-lasting anti-tumor responses.

Methods: Recipient DCs from C3H mouse bone marrow cells were incubated with donor antigen from splenic lymphocytes of C57BL/6 mouse; these DCs were transfected with CD80/86 specific siRNA using lentiviral vectors. Flow cytometry was used to evaluate expression of CD80/86 on the antigen-pulsed recipient DCs.
Colorectal cancer is one of the most common digestive tract malignancies in the world. Owing to the newer and more effective systemic therapies, the life of colorectal cancer patients can be remarkably prolonged, and the incidence of brain metastases is increasing. However, little is known about the underlying mechanisms of brain metastasis from colorectal cancer.

Methods: Vesicular and micellar phases were isolated by the density gradient ultracentrifugation method. Total proteins from the two phases were extracted, and the protein expressional profiles were established by two-dimensional electrophoresis respectively.
