The use of self-expandable metal stents (SEMS) for the treatment of malignant colorectal obstruction is increasing. However, results of risk factors for its complications are inconsistent. This study aimed to examine the clinical effectiveness of the procedure as well as the complications and risk factors associated with the complications. ⋯ Although SEMS in patients with malignant colorectal obstruction is effective both as palliative therapy and as a bridge to surgery, one-third of patients experienced complications. Severity of obstruction and stent type can influence outcomes.

Randomized Controlled Trial Comparative Study
Patient-reported outcomes after single-incision versus traditional laparoscopic cholecystectomy: a randomized prospective trial.
Single-incision laparoscopic cholecystectomy (SILC) is a newer approach that may be a safe alternative to traditional laparoscopic cholecystectomy (TLC) based on retrospective and small prospective studies. As the demand for single-incision surgery may be driven by patient perceptions of benefits, we designed a prospective randomized study using patient-reported outcomes as our end points. ⋯ SILC is a longer operation but can be done at the same cost as TLC. Recovery and pain scores are not significantly different. There may be an improvement in patient satisfaction with wound appearance. Both procedures are valid approaches to cholecystectomy.

The EURO-NOTES Clinical Registry (ECR) was established as a European database to allow the monitoring and safe introduction of Natural Orifice Transluminal Endoscopic Surgery (NOTES). The aim of this study was to analyze different techniques applied and relative results during the first 2 years of the ECR. ⋯ Five years since the introduction of NOTES into clinical practice, hybrid techniques have gained considerable clinical application. Several NOTES hybrid cholecystectomy and appendectomy techniques are practicable and safe alternatives to laparoscopic procedures. Also, sigmoidectomies and peroral esophageal myotomies were described, proving feasibility and safety. Nevertheless, the real benefit of NOTES for patients still needs to be assessed.

The objective of this pilot study was to evaluate the feasibility and safety of natural orifice endoscopic transanal total mesorectal excision (TME) with laparoscopic assistance in a cohort study of five patients with stage I and IIA rectal cancer. ⋯ In this pilot study of five patients with rectal cancer, transanal endoscopic TME with laparoscopic assistance is feasible and safe, and is a promising alternative to open and laparoscopic TME. Evaluation of long-term functional and oncologic outcomes of this approach is needed before widespread adoption can be recommended.

The transanal minilaparoscopy-assisted natural orifice transluminal endoscopic surgery (NOTES) approach holds significant promise as a safe and less morbid alternative to conventional low anterior rectal resection. Previous reports have shown satisfactory short-term oncologic results. We evaluated the safety and short-term outcomes in rectal cancer subjects who underwent transanal minilaparoscopy-assisted natural orifice surgery total mesorectal excision (TME) rectal resection. ⋯ This study demonstrates that transanal NOTES with minilaparoscopic assistance in the hands of a specialized team is safe; meets the oncologic requirements for high-quality rectal cancer surgery; and may offer advantages over pure laparoscopic approaches for visualizing and dissecting out the distal mesorectum. Minilaparoscopic assistance allows one to compensate for the limitations of current NOTES instrumentation to ensure the safety and adequacy of oncologic resection in these difficult cases. Careful patient selection, a specialized team, and long-term outcome evaluation are critical before this procedure can be considered for routine clinical use.
