In early gastric cancer, the aim of surgery is to precisely remove the distal stomach including the primary tumor. To do this, accurate localization of the tumor is crucial, especially in totally laparoscopic surgery. This protocol describes a procedure for intraoperative gastroscopy in totally laparoscopic subtotal gastrectomy.

Financial metrics are essential for understanding a company's performance, helping businesses achieve profitability, and monitoring financial progress. These metrics guide sales targets, cost structures, and marketing effectiveness decisions. Setting target revenues ensures sales cover operating expenses and generate profits. For example, a business planning expansion might set higher sales targets to cover increased operational costs while maintaining profitability. The target revenue is a...

Roux-en-Y Gastric Bypass Procedure: A Bariatric Surgical Procedure for Gastric Resectioning in Murine Model
0 Views •
2025
This video describes a bariatric surgery-Roux-en-Y procedure. This involves the cutting of the jejunum- the middle portion of the intestine- to generate two intestinal limbs. The biliary limb is attached to the existing intestinal loop and the alimentary limb is attached to the stomach, creating a gastric bypass. The gastric bypass created here helps to decrease the nutrient uptake and efficiently reduces body weight.

Margins and profit metrics are crucial for businesses to evaluate their profitability and cost management. By comparing sales revenue to various costs, these metrics help companies make informed decisions about pricing and overall financial strategy. Gross margin represents a company's profit after covering the direct production costs. It highlights the efficiency of managing production. A higher gross margin means the company effectively converts sales into earnings after accounting for the...

The marginal propensity to consume (MPC) describes how much of an additional dollar of disposable income a household is likely to spend rather than save. It provides insight into consumer behavior and is a foundational component in the analysis of fiscal policy effectiveness and national income determination.Concept and MeasurementMPC is measured as the ratio of the change in consumption (ΔC) to the change in disposable income (ΔY), expressed as:MPC = ΔC / ΔYFor example, if an individual's...

Orientation preserves the relationship between the lesion and the cut edge of the resected stomach. After the specimen is oriented, sectioning can sample the relevant boundary systematically, allowing microscopic examination to show whether abnormal or tumor cells reach or approach that edge. This improves the usefulness of the pathology report for assessing completeness of removal.
An involved margin indicates that abnormal or tumor cells extend to the examined resection boundary, whereas a clear margin indicates that such cells are not identified at that edge. This distinction signals whether disease may remain locally and can influence treatment planning, including consideration of further local management or closer follow-up.
Margin findings add information about the local extent of a gastric lesion after resection. They do not replace the broader pathology assessment, but they help show whether the excision reached beyond the abnormal tissue. In gastric cancer and other lesions, this information supports staging, treatment decisions, and evaluation of the likelihood of local control.
The excised stomach specimen is first oriented so the relevant surfaces and boundaries can be identified. It is then sectioned to expose the lesion and its relationship to the cut edge. Pathologists examine the prepared sections microscopically for tumor or abnormal cells at, or near, the margin and report the margin relationship.
If disease extends to the resection boundary, the finding may prompt consideration of additional surgery, endoscopic management, or follow-up, depending on the lesion and clinical circumstances. A clear margin can support the conclusion that the sampled resection removed the identified abnormal tissue. The result therefore connects microscopic findings with subsequent local disease management.
No. Although margin assessment is important in gastric cancer, the same pathology principle can be applied to other gastric lesions requiring excision. Microscopic evaluation determines whether abnormal cells remain at or near the cut edge, helping clinicians judge completeness of removal, plan appropriate management, and monitor for local disease when necessary.
