Frequency of Clinically Significant Findings in the Surgical Pathology Specimen Following Laparoscopic Sleeve Gastrectomy and Concordance with Preoperative Endoscopy: Insights from a Large Single-Center Experience.

Introduction: Endoscopy prior to bariatric surgery is not always performed, and in sleeve gastrectomy (SG), the surgical specimen is not always sent for pathological examination. There is limited data on the frequency of clinically significant findings in SG specimens or correlation with preoperative endoscopy.

Methods: We reviewed 426 consecutive SG patients to determine the concordance of preoperative endoscopy findings in patients with clinically significant postoperative pathology.

Optimising Electroporation Condition for CRISPR/Cas-Mediated Knockout in Zona-Intact Buffalo Zygotes.

Somatic cell nuclear transfer or cytoplasm microinjection has widely been used to produce genome-edited farm animals; however, these methods have several drawbacks which reduce their efficiency. In the present study, we describe an easy adaptable approach for the introduction of mutations using CRISPR-Cas9 electroporation of zygote (CRISPR-EP) in buffalo. The goal of the study was to determine the optimal conditions for an experimental method in which the CRISPR/Cas9 system is introduced into in vitro-produced buffalo zygotes by electroporation.

Ectopic adrenal tissue in a cat that underwent an ovariohysterectomy.

Objective: To describe the use of ultrasound and adrenal function testing to confirm that excised periovarian tissue is normal ectopic adrenal tissue (EAT).

Animal: A 6-month-old female domestic shorthair cat.

Clinical Presentation, Progression, And Procedures: The cat underwent an ovariohysterectomy procedure, during which abnormal tissue was discovered adjacent to both ovaries.

Electroporation-based CRISPR gene editing in adult buffalo fibroblast cells.

Electroporation is a widely used method for delivering CRISPR components into cells; however, it presents challenges when applied to difficult-to-transfect cells like adult buffalo fibroblasts. In this study, the gene (encoding the CD18 protein), plays vital for cellular adhesion and immune responses, was selected for editing experiments. To optimize electroporation conditions, we investigated parameters such as electric field strength, pulse duration, plasmid DNA amount, cuvette type, and cell type.

Palliative Endoscopic Salvage of a Functionally Obstructed Gastrojejunostomy - Report of Technique.

Background: Gastric outlet obstruction secondary to foregut gastrointestinal malignancies can be managed with a variety of medical, endoscopic, and surgical options. Laparoscopic gastrojejunostomy is an option for those patients who are able to tolerate an operation as a long-term palliative option. This operation may be associated with some significant postoperative technical and nontechnical complications, including delayed gastric emptying.
