An accurate and reliable localization of endoluminal gastrointestinal (GI) lesions is crucial, particularly during minimally invasive surgery. As an extreme consequence, a misdetected GI lesion can lead to the resection of the wrong segment, especially in colorectal surgery. A preoperative endoscopic marking is recommended in case of GI lesions, which are expected to be difficult to detect from the serosal side. In clinical practice, three preoperative endoscopic marking methods are currently used: India ink, SPOT™, and endoclips with intraoperative fluoroscopy. All of them have substantial limitations. This has encouraged research on alternative solutions. In the current systematic review, animal and clinical studies about alternative preoperative endoscopic marking methods of GI lesions were analyzed using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Thirty studies were found using PubMed/MEDLINE, EMBASE/Ovid, and the Cochrane Library for the qualitative analysis. Although several smart solutions have been proposed and tested successfully, all of them seem to have a substantial drawback related either to scarce stability on the marking site or potential spreading on the bowel wall or diffusion into the surgical planes.

Background: Mapping biopsy (MB) can evaluate superficial ductal spread (SDS) through the histopathological diagnosis of cholangiocarcinoma, enabling the selection of an appropriate surgical procedure. This retrospective study evaluated the efficacy of MB using a novel sheath system in distal cholangiocarcinoma (dCCA) cases.
Methods: A total of 199 cholangiocarcinoma cases underwent preoperative diagnosis.
Long-term Outcomes of Endoscopic Radiofrequency Ablation versus Endoscopic Submucosal Dissection for Widespread Superficial Esophageal Squamous Cell Neoplasia.

Background/aims: Endoscopic radiofrequency ablation (ERFA) is a treatment option for superficial esophageal squamous cell neoplasia (ESCN), with a relatively low risk of stenosis; however, the long-term outcomes remain unclear. We aimed to compare the long-term outcomes of patients with widespread superficial ESCN who underwent endoscopic submucosal dissection (ESD) or ERFA.
Methods: We retrospectively analyzed the clinical data of patients with superficial ESCN who underwent ESD or ERFA between January 2015 and December 2021.

Percutaneous nephrolithotomy (PCNL) is a widely preferred method for treating complex kidney stones, particularly in patients with larger or more complicated stones. Despite its advantages, such as minimal invasiveness and a shorter recovery time, postoperative complications can occur, thereby necessitating effective risk assessment tools to identify at-risk patients. This study evaluated the Estimation of Physiologic Ability and Surgical Stress (E-PASS) scoring system's utility in predicting postoperative complications following standard PCNL.

Background: Approximately 103 million people across the globe suffer from symptomatic lumbar spinal stenosis, impacting their health and quality of life. The unilateral biportal endoscopic technique is effective for treating single-segment degenerative lumbar spinal stenosis and is seen as a viable alternative to traditional open lumbar laminectomy. However, research on the application of this technique for multilevel lumbar spinal stenosis remains lacking.

Background: An all-inside endoscopic flexor hallucis longus (FHL) tendon transfer is indicated for the treatment of chronic, full-thickness Achilles tendon defects. The aim of this procedure is to restore function of the gastrocnemius-soleus complex while avoiding the wound complications associated with open procedures.
Description: This procedure can be performed through 2 endoscopic portals, a posteromedial portal (the working portal) and a posterolateral portal (the visualization portal).
