Purpose: Palliation of patients with unresectable colorectal carcinoma is an effective treatment and technical failure is undesirable. Insertion of colorectal stent using a combined radiologic and colonoscopic technique may be technically limited by the ability to negotiate tortuous bends, particularly if the bowel is fixed.
Methods: We used a through scope sphincterotome, which improved the ability to traverse difficult strictures.
Results: We have used the technique in four cases as a last resort. This resulted in a technical success in all four cases (100 percent).
Conclusions: Sphincterotome is a useful adjunct in stenting difficult colorectal tumor strictures.

Colorectal cancer (CRC) is a leading cause of cancer mortality, with many patients presenting with malignant colorectal obstruction (MCO). Self-expandable metal stents (SEMSs) have emerged as a minimally invasive key intervention, both as a bridge to surgery (BTS) in curative setting sand for palliation in advanced disease. This review aims to provide an evidence-based analysis of SEMS indications, contraindications, and efficacy across curative and palliative contexts, with focus on long-term outcomes.

Despite the unique properties of clay nanocomposites for cardiovascular applications, there are few data on the hemocompatibility of these nanomaterials. This study represents the first comprehensive investigation of the hemo/biocompatibility of clay nanocomposites . Nanocomposite coatings of polylactic acid (PLA)-polyethylene glycol (3 wt %)-Cloisite20A nanoclay (3 wt %) were produced using electrospraying technique as potential drug-eluting stent (DES) coatings.

Background And Aims: Self-expandable metal stents (SEMS) are effective in alleviating malignant colorectal obstruction. However, bowel perforation following SEMS placement remains a significant concern, as it can adversely affect oncological outcomes. This study aimed to evaluate the recurrence and overall survival rates associated with SEMS-related bowel perforations.

Background: Malignant bowel obstruction (MBO) is a common complication in advanced and recurrent gynecologic malignancies, with limited treatment options and poor prognosis. Self-expanding metallic stent (SEMS) insertion has emerged as an alternative palliative measure, yet data specific to gynecologic malignancies remains scarce.
Methods: A retrospective analysis was conducted on 61 patients with gynecologic malignancies and malignant large bowel obstruction who underwent colorectal stenting between January 2002 and December 2023.

Objective: To investigate the optimal interval between self-expanding metal stent (SEMS) placement and radical surgery in patients with obstructive colorectal cancer.
Method: In this study, a retrospective research design was used to select 125 patients with obstructive colorectal cancer who underwent colonoscopic SEMS placement with subsequent radical surgery between February 2011 and November 2022 at Shanghai Changhai Hospital. In addition, their clinical data and therapeutic efficacy were examined.
