Revisional Bariatric Surgery

- 0 min read

Revisional Bariatric Surgery, oftentimes denoted as ancillary bariatric surgery, constitutes a distinct operation executed by adept bariatric practitioners. This particular surgical intervention caters primarily to those who have pursued antecedent weight reduction surgeries, yet did not attain the coveted outcomes or encountered complications. Revisional Bariatric Surgery encompasses the adjustment or modification of the erstwhile surgical undertaking to rectify issues that might have surfaced or to bolster the weight loss process further.

Pertaining to a scholarly investigation by Frantzides et al, the prevalence of recalibrations contingent upon primary surgical methods exhibits variation. As an illustration, roughly 30 percent of patients possessing a Vertical Banded Gastroplasty (VBG) necessitated a recalibration. In the case of patients bestowed with an Adjustable Gastric Band (AGB), the recalibration rate oscillated between 10 and 60 percent. Moreover, for individuals who underwent a Gastric Bypass (GBP), 15 to 35 percent mandated a recalibration. (3)

Definition and Overview

Revisional bariatric surgery, often referred to as secondary bariatric surgery, is an operation done on people who have had weight reduction surgery in the past who either did not achieve the intended weight loss results or had difficulties. It is a specialist surgical technique created to deal with problems that may have developed following the initial weight reduction surgery, such as insufficient weight loss, weight return, or medical consequences.

Usually, the patient and the bariatric surgical team deliberate and then decide whether to proceed with revisional bariatric surgery. Depending on the unique circumstances of the patient, the type of first weight reduction surgery done, and the underlying causes of the poor results, the revisional treatment that is carried out will vary.


The individual demands and circumstances of each patient will determine how the revisional bariatric surgery is performed. To choose the best revisional strategy, the surgical team will consider the patient's medical background, previous weight reduction surgery operation, current health status, and anticipated objectives.

Typical revision techniques include:

  • Conversion: To address the problems discovered, the initial weight reduction surgery method may occasionally be changed to a new kind of procedure. A gastric band, for instance, could be changed to a gastric bypass or sleeve gastrectomy.
  • Revisional surgery may entail making revisions to or repairs to an earlier procedure for weight loss. A gastric band may need to be resized or repositioned, a gastric sleeve may need to be stitched or reinforced, or the link between the stomach and intestines may need to be adjusted during a gastric bypass.
  • Reversal: A reversal treatment may be undertaken in rare circumstances where the first weight loss surgery has led to serious problems or intolerable adverse effects. This entails putting the anatomy back to how it was before the operation.
  • During meetings with the bariatric surgical team, the precise details of the revisional bariatric surgery operation will be covered in detail. The surgical team will provide you all the information you need, including possible risks, advantages, and anticipated results.

Revisional Bariatric Surgery Risks and Side Effects

According to the Mayo Clinic, bariatric surgery, a substantial medical intervention, comes with risks that could manifest shortly after the procedure or emerge as long-term complications.

Immediate surgical risks include:

  • The potential for heavy bleeding.
  • Infection risks inherent to surgical interventions.
  • Adverse reactions to anesthesia.
  • The possibility of blood clot formation.
  • Respiratory complications.
  • Leaks within the gastrointestinal tract.
  • Death, although it is a rare occurrence.

Long-term complications may encompass:

  • Obstructions in the bowel.
  • Dumping syndrome causing gastrointestinal and systemic symptoms.
  • Formation of gallstones.
  • Development of hernias.
  • Episodes of hypoglycemia.
  • Risks of malnutrition.
  • Emergence of ulcers.
  • Frequent vomiting.
  • Issues with acid reflux.
  • The possibility of needing revisional surgery.

As per Ji Yeon Park’s findings on NCBI, revisional bariatric procedures present a heightened risk profile 19%-50%, with postoperative complications ranging widely in incidence.


People who have previously undergone weight reduction surgery but have not met their targeted weight loss goals or have suffered difficulties are candidates for revisional bariatric surgery. Revisional surgery is frequently considered for the following causes:

  • Insufficient Weight reduction: After their initial weight reduction surgery, some patients may not have lost enough weight or may have gained a lot of it back. These problems can be addressed with revisional surgery, which also offers a fresh chance for weight loss success.
  • Medical difficulties: Following the initial weight loss surgery, there may be certain difficulties or side effects, such as gastric band slippage or erosion, reflux disease, or persistent nausea. These issues can be lessened by revisional surgery, which also enhances general health and wellbeing.
  • Change in Health Status: Patients who have initial weight loss surgery but whose health has since changed may benefit from revisional surgery. This includes those who, despite the initial surgery, have had weight-related health problems or additional medical illnesses.
  • Desire for a Different Procedure: Some people may want a different kind of weight-loss surgery than what they had for their initial operation. This can be the result of individual preferences or modifications in surgical developments that provide better results.

The bariatric surgical team will thoroughly assess any candidates for revisional bariatric surgery. To establish eligibility and the best revisional strategy, the evaluation will take into account elements including general health, prior surgical history, present weight, and personal goals.


The right post-operative care is essential for optimal healing and recovery following revisional bariatric surgery. The bariatric surgery team will give specific advice on how to care for yourself after the treatment, including:

  • Hospital Stay: The exact revisional operation carried out and the person's general condition will determine how long they need to stay in the hospital. During the first phase of healing, careful observation is crucial.
  • Pain control: Patients will receive pain medication to treat any discomfort or pain they may feel following surgery. It's crucial to adhere to the recommended pain management strategy for a speedy recovery.
  • Dietary Recommendations: The recommended diet after revisional bariatric surgery will vary depending on the operation. A liquid or pureed diet may be advised at first, with the addition of solid foods as tolerated. The bariatric surgical team will give specific dietary and nutritional guidelines.
  • Activity and Exercise: After surgery, the surgical staff will give instructions on how to gradually resume physical activity and exercise. To encourage healing and prevent complications, it's crucial to abide by these recommendations.
  • Follow-up Appointments: The bariatric surgical team will plan many follow-up consultations to keep track of your progress, address any issues you may have, and offer support while you recuperate.


The precise method carried out, the person's capacity for healing, and adherence to post-operative instructions are few examples of the variables that can affect the timing for witnessing the outcomes of revisional bariatric surgery. Revisional bariatric surgery is a technique that can promote weight loss and better health, but in order to be successful in the long run, it requires commitment and lifestyle modifications.

In certain situations, people may lose some weight at first in the weeks after surgery. However, as the body adjusts to the modified structure and the individual adopts a healthy lifestyle, the full results and sustained weight loss will happen gradually over a number of months.
