Background: Olfactory neuroblastoma, or esthesioneuroblastoma (ENB), is an uncommon sinonasal malignancy arising from olfactory neuroepithelium that is optimally treated with surgical resection. The objective of this study is to determine preoperative predictors of undergoing open versus endoscopic approach for ENB and to investigate significant postoperative survival outcomes between the two surgical approaches.
Methods: The National Cancer Database (NCDB) was queried for cases of ENB histology that were treated surgically from 2010 to 2015. Groups were stratified into open or endoscopic approach cohorts. Patient demographics, tumor characteristics, treatment modality, and 5-year overall survival were compared between the two groups using Chi-Square analysis and Kaplan-Meier survival analysis. Cases were classified as Kadish stage A, B, C, or D based on the "Collaborative Stage-Extension" codes in NCDB.
Results: Of 533 patients meeting inclusion criteria, 276 (51.8%) patients underwent open, and 257 (48.2%) patients underwent endoscopic surgical approaches. Patients undergoing endoscopic surgery were more likely to be Kadish stages A and B and less likely to be stages C and D ( = .020). Those undergoing endoscopic approach overall had a shorter mean hospital stay postoperatively (3.8 vs. 7.0 days, < .001). Endoscopic cases had a greater 5-year overall survival (81.9% vs. 75.6%, = .030); after multivariate regression, there was a trend toward survival benefit to endoscopic surgery that did not reach clinical significance (HR 0.644, [0.392-1.058], = .083).
Conclusion: Although not statistically significant, there is a trend toward increased overall survival with an endoscopic approach in patients undergoing surgery for ENB as compared to an open approach, regardless of Kadish stage. An endoscopic approach is an adequate alternative to an open approach for the surgical treatment of ENB.

Background: Patients with prior abdominal surgeries are at higher risk of intra-peritoneal adhesions near the trocar entry site, increasing the likelihood of organ injury during laparoscopic cholecystectomy (LC). This study evaluates a novel technique where the epigastric trocar is inserted first, after creating pneumoperitoneum, to allow safe dissection of adhesions under direct vision before placing the umbilical trocar.
Methods: This prospective study included 244 patients with symptomatic uncomplicated gallstone disease and a history of previous abdominal surgeries extending to the umbilicus.

Pineal gland lesions pose a significant surgical challenge due to the deep-seated nature of the pineal gland, as well as the limited field of view, and the complex vascular anatomy. The mainstay of surgical treatment, when necessary, is always histopathological clarity and gross total resection (GTR). We evaluate the surgical outcomes for pineal gland lesions, shedding light on functional outcomes, histological findings, and surgical complications.

Lynch syndrome is the most common hereditary cancer predisposition, accounting for 1-5% of colorectal cancer cases, and is driven by germline mutations in DNA mismatch repair genes. Despite established diagnostic criteria, such as the Amsterdam guidelines, Lynch syndrome remains largely underdiagnosed. To address this gap, universal tumour screening has been introduced for all newly diagnosed cases of colorectal cancer and endometrial cancer, significantly improving early detection.

An 83-year-old male presented to our Digestive System Department with a 5-day history of severe gastrointestinal (GI) bleeding and a 14-year history of idiopathic thrombocytopenic purpura (ITP) with low platelet levels. Colonoscopy revealed extensive telangiectasias throughout the colon, particularly in the transverse and ascending segments. Standard treatment with proton-pump inhibitors and somatostatin proved ineffective.

Objectives: Mismatch repair (MMR)-deficient (dMMR) colorectal cancer (CRC) have been largely categorized into three subtypes: methylated, Lynch syndrome (LS)-associated, and Lynch-like syndrome (LLS)-associated. No studies have examined the prevalence and subtypes of synchronously diagnosed dMMR CRCs in detail. Therefore, this study aimed to examine the frequency and molecular characteristics of the dMMR status among multiple synchronous CRCs to clarify the clinical significance of identifying patients with such tumors.
