Article Abstract
Aim: To compare the efficacy and safety of endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) for the treatment of colorectal tumors.
Methods: Databases, such as PubMed, EMBASE, Cochrane Library and Science Citation Index updated to 2013 were searched to include eligible articles. In the meta-analysis, the main outcome measurements were the en bloc resection rate, the histological resection rate and the local recurrence rate. Meanwhile, we also compared the operation time and the incidence of procedure-related complications.
Results: Six trials were identified and a total of 1642 lesions were included. The en bloc resection rate was higher and the local recurrence rate was lower in the ESD group compared with the EMR group (OR = 7.94; 95%CI: 3.96-15.91; OR = 0.09; 95%CI: 0.04-0.19). There was no significant difference in histological resection rate(OR = 1.65; 95%CI: 0.29-9.30) and procedure-related complication rate between the two groups (OR = 1.59; 95%CI: 0.92-2.73). The meta-analysis also showed that ESD was more time consuming than EMR.
Conclusion: Compared with EMR, ESD results in higher en bloc resection rate and lower local recurrence rate for the treatment of colorectal tumors, without increasing the procedure-related complications.

Community-level social capital and postoperative outcomes following intracranial tumor surgery: an exploration of the Social Capital Atlas in neurosurgical oncology.
J Neurooncol

Department of Neurosurgery, Johns Hopkins School of Medicine, Baltimore, MD, USA.
Background And Objectives: Explore whether community social capital measures (system of resources available to individuals through community engagement) are related to surgical outcomes among intracranial tumor patients.
Methods: Adults who underwent resection at a single medical center for intracranial tumor was identified and their zip codes were matched to three variables derived from the Social Capital Atlas: economic connectedness, volunteering rate, and civic organizations. The economic connectedness score quantifies the degree to which low-income and high-income community members are friends with each other, the volunteering rate is defined as the proportion of a given community engaged in community organizations and the civic organization score is defined as the number of local civic organizations within a given community.
Impact of weight classes on feasibility, safety, and efficacy of awake craniotomy for brain lesions within eloquent areas.

Awake craniotomy is the gold standard to achieve maximal safe resection of brain lesions located within eloquent areas. There are no established guidelines to assess patient's eligibility for awake craniotomy by weight class. This study assesses feasibility, safety, and efficacy of awake surgery by weight classes through an observational, retrospective, single-institution cohort analysis (2010-2024) of 526 awake craniotomies.

Background: Spleen-preserving distal pancreatectomy by robotic surgery is a safe and feasible surgical technique. Currently, spleen-preserving distal pancreatectomy represents an alternative to the classical distal pancreatectomy with splenectomy, in the case of benign and low-grade malignant diseases of the body or pancreas tail. The reasons for preserving the spleen are based on the reduction of postoperative complications, such as post-splenectomy infections, subphrenic abscess, portal thrombosis, pulmonary hypertension, thrombocytosis, and thromboembolism.

Introduction: Three-dimensional printing (3DP) technology has increasingly gained attention in orthopedic oncology, where complex tumor resections and reconstructions demand high precision. 3DP enables the creation of patient-specific models and prostheses, which can improve postoperative quality of life for patients while assisting surgeons in preoperative planning, enhancing surgical accuracy, and improving outcomes in complex oncologic cases. Despite its potential, comprehensive data on the effectiveness and applications of 3DP in orthopedic oncology are limited.
