Revision Surgery in Nashville, Tennessee

Revision surgery is performed when a previous weight loss procedure no longer provides the expected results or causes complications. For some patients, weight regain, reflux, or unresolved health conditions make it necessary to revisit their original surgery. In other cases, older procedures—like the Lap Band—may need to be removed or converted to a more effective option such as a Sleeve Gastrectomy or Gastric Bypass.

At Tennessee Style Weight Loss, Dr. Jameil Abou-Hanna specializes in revisional bariatric procedures. These surgeries are carefully tailored to each patient’s history and current needs, whether that means adjusting a sleeve, converting to bypass, or addressing complications from earlier operations. The goal is not only to restore weight loss, but also to improve safety, comfort, and long-term health outcomes.

Amazing results are achieved with the right plan!

How Revision Surgery Works

Revision surgery isn’t a single procedure — it’s a customized approach to correcting or converting a previous bariatric surgery. Depending on the patient’s needs, this may involve resizing a sleeve, converting a sleeve to a gastric bypass, removing or replacing a Lap Band, or addressing complications from an older Roux-en-Y. Each revision is planned around your medical history, current health, and long-term goals, making it one of the most individualized types of bariatric care.

Who Is It For?

Revision surgery may be recommended for patients who:

Experienced weight regain after a previous bariatric procedure
Are dealing with complications such as reflux, intolerance, or band slippage
Had an older procedure (like Lap Band) that no longer works as intended
Need a different type of surgery to better manage conditions linked to obesity

These surgeries are designed for patients who have already undergone a bariatric procedure but require a new path forward to achieve safe, lasting results.

Types of Revision Surgeries

Step 1

Bypass Revision

A gastric bypass can sometimes require adjustment if weight loss slows down, complications develop, or symptoms like reflux appear. Revision may involve resizing the pouch, tightening the connection, or modifying the bypass to restore results and improve comfort.

Step 2

Sleeve to Bypass

For patients who initially had a sleeve gastrectomy but are now dealing with reflux, weight regain, or limited weight loss, converting the sleeve to a gastric bypass offers stronger, more durable results. This combines restriction with malabsorption to achieve better long-term success

Step 3

SADI Conversion

In cases where patients need a more powerful procedure, a previous sleeve or bypass can be converted to SADI (Single Anastomosis Duodeno-Ileal Bypass). By combining restriction with a simplified malabsorptive process, SADI provides significant weight loss and better management of obesity-related conditions.

Step 4

Other Revisions

Not every situation fits neatly into one category. Some patients require correction for complications such as strictures, intolerance, or pouch enlargement. These revisions are tailored to the individual, with the goal of restoring both safety and effective weight management.

Pre-Op Preparation

Preparing for gastric bypass starts before you ever enter the operating room. In the weeks leading up to surgery, you’ll follow a special high-protein, low-calorie diet designed to shrink the liver. Since the liver often enlarges with obesity, reducing its size makes it easier for the surgeon to safely reach the stomach and lowers the chance of complications.

This stage is also about laying the groundwork for life after surgery. You’ll receive guidance on vitamins, hydration, and meal planning, along with lifestyle adjustments that set you up for long-term success. These preparations aren’t just short-term requirements—they’re the first step in building the habits that will carry you through recovery and beyond.

Post-Op Recovery

Healing after gastric bypass takes time, but it follows a clear path. The goal is to let your body recover while helping you adjust to eating smaller amounts and absorbing fewer calories. Because bypass combines restriction and malabsorption, paying attention to nutrition and supplements is especially important.

Early Recovery (First 2 Weeks)

Most patients spend 1–2 days in the hospital for monitoring.
Walking within 24 hours helps circulation and speeds recovery.
Pain is controlled with medication, and clear liquids are introduced gradually.
The main focus is hydration, gentle movement, and rest.

Adjustment Phase (Weeks 3–6)

Diet shifts from pureed foods to soft meals, eaten slowly in very small portions.
Daily vitamins and supplements become part of your routine.
Light activity and a return to work are possible, depending on how you feel.
Protein intake and hydration remain top priorities.

Long-Term Recovery (After 6 Weeks)
