• Introduction

Revisional bariatric surgery is a weight loss surgery for people who have not lost enough weight or have regained weight after their first bariatric surgery. It is a complex and technically demanding procedure, but it can be a successful treatment option for patients with weight regain.

• Causes of Weight Regain

There are many factors that can contribute to weight regain after bariatric surgery, including:

* Lack of adherence to dietary recommendations
* Hormonal/metabolic imbalance
* Mental health
* Physical inactivity
* Anatomic/surgical factors
* Medications

• Preoperative Evaluation

Before revisional surgery, patients will undergo a thorough evaluation to determine if they are eligible for the procedure. This evaluation will include a medical history and physical exam, as well as blood tests, imaging studies, and a psychological evaluation.

• Selecting the Type of Revisional Surgery

The type of revisional surgery that is best for a patient will depend on a number of factors, including the type of primary surgery they had, the cause of their weight regain, and their overall health. Some of the most common types of revisional surgery include:

* Roux-en-Y gastric bypass (RYGB)
* Sleeve gastrectomy (SG)
* Biliopancreatic diversion with duodenal switch (BPD/DS)
* Single anastomosis gastric bypass (OAGB)
* Sleeve gastrectomy with duodenal switch (SADI-S)

• Weight Loss Following Revisional Surgery

Weight loss after revisional surgery can be significant. In one study, patients who underwent revisional surgery for weight regain lost an average of 50–65.3% of their excess weight after 3 months and 50.1–79.1% of their excess weight after 12 months.

• Complications of Revisional Surgery

Revisional surgery is more complex and technically demanding than primary bariatric surgery, and therefore carries a higher risk of complications. Some of the most common complications of revisional surgery include:

* Hernia
* Anastomotic leak
* Stricture
* Marginal ulcer
* Wound infection
* Hemorrhage
* Perforation
* Obstruction

• Conclusion

Revisional bariatric surgery can be a successful treatment option for patients with weight regain. However, it is important to carefully consider the risks and benefits of the procedure before making a decision. Patients should also work closely with their healthcare team to choose the best type of revisional surgery for them and to prepare for the procedure and its aftermath. Revisional bariatric surgery is a complex and technically demanding procedure, but it can be a successful treatment option for patients with weight regain. It is important to work closely with your healthcare team to determine if you are eligible for the procedure and to choose the best type of surgery for you.
