Introduction: Revolution Obesity surgeries In modern medicine

Over the last decade, it has become Obesity surgeries One of the most important medical fields that has revolutionized the treatment of weight-related diseases is bariatric surgery. It is no longer a cosmetic option or a luxury, as some might think, but rather a necessary medical intervention to protect the lives of hundreds of thousands of patients worldwide. Obesity is now considered one of the most dangerous diseases of our time, and is directly linked to diabetes, high blood pressure, bone diseases, sleep apnea, and heart problems.

With advancements in medicine, patients now have several options within bariatric surgery, most notably: Quantification, classical bypass, mini-bypass, and SASI procedure. Although all these procedures aim to reduce weight and improve health, each procedure differs radically in its mechanism of action, benefits, and complications.

In this article, we will redraw the complete picture of obesity surgeries, with a detailed explanation of each procedure, a comprehensive comparison, and tips to help you make your decision with confidence. Obesity surgeries

First: Gastric sleeve surgery (Gastric Sleeve)

The gastric sleeve procedure is considered one of the most famous Obesity surgeries Absolutely, and millions of patients rely on it annually due to its effectiveness and ease of procedure. It is the first choice for many surgeons thanks to its excellent results and high safety profile.

How is the gastric sleeve procedure performed?

The sleeve gastrectomy procedure involves removing approximately 70%–80% of the stomach, leaving a thin, sleeve-like or banana-shaped portion. This reduction results in:

Reducing the amount of food that can be eaten
Reducing the secretion of the hunger hormone (Ghrelin)
Feeling full quickly

This surgery is performed laparoscopically through several small incisions in the abdomen.

Advantages of gastric sleeve surgery – Obesity surgeries

Significantly reduce appetite Thanks to the removal of the part responsible for the hunger hormone.
It does not involve a change in the intestinal tract.This means natural absorption of nutrients.
Strong and consistent results For those who adhere to a healthy lifestyle.
Short surgical time Compared to conversion processes.
Suitable for people who eat large quantities of food, more so than those who love sweets.

Disadvantages of gastric sleeve surgery – Obesity surgeries

irreversible Because part of the stomach is permanently removed.
It may worsen the problem of acid reflux. Some patients have it.
Weight may return to normal later if the diet is not followed.

Second: The classic Roux-en-Y conversion process

The classic track conversion is called the “gold standard” in the world Obesity surgeries. It is the ideal option for patients with type 2 diabetes or severe reflux.

Working mechanism

The process consists of two steps:

1. Reducing stomach size – Obesity surgeries

A very small part of the upper stomach is separated to become the primary pocket that receives food.

2. Bypassing part of the intestine

This pouch is connected directly to the small intestine, bypassing the duodenum and the first part of the small intestine.

Advantages of Classic Track Switching

Powerful treatment for diabetes It reaches a healing rate exceeding 85%.
The best solution for reflux Undoubtedly.
Fast and effective weight loss Thanks to reduced quantity and poor absorption combined.

Defects of route diversion

The patient needs vitamins lifelong.
More complicated than gastric sleeve surgery.
Dumping syndrome may occur when consuming sugars.

Third: Mini Gastric Bypass – Obesity surgeries

This process is a simpler and faster version of the classic conversion, and it has very strong results.

The idea of the process

A long gastric pouch is created and connected to the intestines with only one connection; this reduces surgery time and makes it easier. Obesity surgeries

Features of mini-path conversion

Very effective in weight loss. Obesity surgeries
It can be modified or cancelled in some cases. Obesity surgeries
Suitable for patients with severe obesity.
Very effective for diabetics.

Disadvantages of mini-path conversion

Possibility of biliary reflux (rare in the classic case).
Vitamin and mineral deficiencies become more apparent if treatment is not followed.

Fourth: The SASI Bypass Process

From the latest Obesity surgeries And it has become increasingly popular in recent years. SASI is a hybrid procedure that combines the benefits of both gastric sleeve and gastric bypass. Obesity surgeries

How does the SASI process work?

Gastric sleeve surgery is performed.
Then a connection is made between the lower part of the stomach and the intestines. Obesity surgeries

Thus, food has two pathways:

30% passes through the normal path
70% is heading to the sidepath (like a switch). Obesity surgeries

Advantages of the Sassi process

Fewer vitamin deficiencies compared to complete conversion. Bariatric surgery.
Very suitable for diabetics and those with high obesity.
It does not cause bile reflux.
Excellent results in weight loss.

Disadvantages of the SASI process

Relatively recent and there are no long-term studies.
You need a very experienced surgeon to achieve the best results.

Fifth: A comprehensive comparison table between obesity surgeries

Working mechanism	Quantity restriction	Restriction + Malabsorption	Restriction + Malabsorption	Restriction + Partial Malabsorption
Operation time	45–60 minutes	90–120 minutes	60–90 minutes	60–90 minutes
reflux	It may increase	The best treatment for reflux	Bile reflux may occur	Relatively safe
Diabetes treatment	70%	+85%	+85%	+85%
Vitamins	most likely year	lifelong	lifelong	Lifetime (lighter)
weight loss	60–70%	70–80%	75–85%	70–80%
