Single Anastomosis Duodenal-Ileal Bypass with Sleeve Gastronomy (SADI-S)

Summary

The video discusses a surgical procedure for accessing the abdominal cavity through small incisions, using trocars for instrument passage. It details the gastric sleeve surgery, starting with sleeve gastrectomy to create a vertical sleeve from the stomach, which holds about 100-150 milliliters. The small bowel is then reconfigured, altering the gastrointestinal tract's anatomy. This surgical approach leads to reduced hunger and increased satiety after meals, highlighting the procedure's effectiveness in weight management.

Takeaways

• 🔍 Small incisions are made in the abdomen to access the abdominal cavity for surgery.
• 🔧 Trocars are inserted to allow surgical instruments to pass through the incisions.
• 📹 A laparoscope or video camera is used for visual examination of the abdomen during the procedure.
• 🍽️ The average human stomach can expand to hold approximately one to one and a half liters of food.
• 🧪 Food in the stomach is combined with digestive enzymes, aiding in its breakdown for easier digestion and absorption.
• 🛠️ Sleeve gastrectomy begins with creating a thin vertical sleeve of the stomach using a stapling device.
• 🍌 The gastric sleeve created typically holds between 100 and 150 milliliters, about the size of a banana.
• ❌ The resected portion of the stomach is removed during the procedure.
• 📏 The small bowel is divided approximately three centimeters beyond the stomach while preserving the pylorus.
• 🔄 Altering the gastrointestinal tract leads to decreased hunger and increased feelings of fullness after meals.

Q & A

What is the purpose of creating small incisions in abdominal surgery?

Small incisions are created to access the abdominal cavity, allowing the insertion of trocars that serve as passageways for surgical instruments.

What role does the laparoscope play in abdominal surgery?

The laparoscope, or video camera, allows the surgeon to examine the abdomen during the procedure.

How much food can the average human stomach expand to hold?

The average human stomach can expand to hold approximately one to one and a half liters of food.

What happens to food in the stomach?

Food is combined with digestive enzymes in the stomach, which help break it down into simpler forms for easier digestion and absorption in the small bowel.

What is a sleeve gastrectomy?

A sleeve gastrectomy is a surgical procedure that creates a thin, vertical sleeve of the stomach using a stapling device, typically holding between 100 and 150 milliliters.

What is the size of the stomach sleeve created during the procedure?

The stomach sleeve created during a sleeve gastrectomy is about the size of a banana.

What happens to the portion of the stomach that is resected?

The resected portion of the stomach is removed during the surgery.

How is the small bowel involved in the procedure?

The small bowel is divided approximately three centimeters beyond the stomach, and about three meters of the small bowel are measured and brought up to join with the duodenum.

What physiological changes occur as a result of creating a gastric sleeve?

Creating a gastric sleeve and altering the anatomy of the small bowel changes signals in the body, resulting in decreased hunger and increased feelings of fullness after meals.

What is the significance of preserving the pylorus during the surgery?

Preserving the pylorus is important for maintaining normal gastric function and digestive processes after the surgery.
