Individuals considering weight loss surgery often wonder if a pre-existing hernia might prevent them from undergoing the procedure. This article explores how weight loss surgery and hernia management intersect, providing insights into managing both conditions.
Weight Loss Surgery and Hernias Explained
Weight loss surgery, also known as bariatric surgery, involves altering the digestive system to promote significant weight reduction. These procedures typically reduce the stomach’s size or reroute the small intestine, leading to decreased food intake and nutrient absorption. The goal is to address severe obesity and related health conditions.
A hernia occurs when an internal organ or tissue pushes through a weak spot in the surrounding muscle or connective tissue that normally holds it in place. Hernias are most common in the abdomen or groin region. Two types frequently encountered in individuals considering bariatric surgery are hiatal hernias and abdominal wall hernias. A hiatal hernia involves the upper part of the stomach pushing through the diaphragm into the chest, while abdominal wall hernias, such as umbilical or incisional hernias, occur at weaknesses in the abdominal wall itself.
Having Both Conditions
It is often possible for individuals with a pre-existing hernia to undergo weight loss surgery, though it requires careful evaluation by a surgical team. The approach is highly individualized, depending on factors related to the hernia and the patient’s overall health. Surgeons assess the hernia’s type, size, symptoms, and the specific bariatric procedure being considered.
Obesity contributes to hernia development and recurrence due to increased intra-abdominal pressure and weakened connective tissues. Hiatal hernias are common among bariatric surgery candidates. Abdominal wall hernias, including incisional hernias from previous surgeries, are also frequently observed. A thorough pre-operative assessment helps determine the most appropriate course of action, balancing the benefits of weight loss with the need for hernia management.
Managing Hernias During Bariatric Surgery
In many instances, a hernia can be repaired during the same operation as the weight loss surgery, a strategy known as a combined or simultaneous procedure. For hiatal hernias, concurrent repair during bariatric surgery is a common practice, aiming to reduce the risk of gastroesophageal reflux disease-related complications. Studies suggest that repairing hiatal hernias simultaneously with bariatric surgery is safe and feasible.
Surgical techniques for hernia repair during bariatric surgery often involve either an open or laparoscopic approach. Laparoscopic (minimally invasive) techniques, which use small incisions and a camera, are frequently employed for both bariatric procedures and many hernia repairs. Surgical mesh may also be incorporated to reinforce weakened tissue and provide additional support. While simultaneous repair is common, some complex cases, such as very large hernias, might lead surgeons to consider a staged approach. In this approach, bariatric surgery is performed first, followed by hernia repair after significant weight loss. This staged approach may improve outcomes for complex abdominal wall hernias by reducing intra-abdominal pressure.
Life After Combined Surgery
Patients undergoing combined hernia repair and weight loss surgery can expect a recovery process that integrates aspects of both procedures. Weight loss after bariatric surgery can significantly reduce intra-abdominal pressure, which is beneficial for hernia management and can lower the risk of future hernia development or recurrence.
While combined procedures are generally effective, a potential for hernia recurrence exists, though it is often lower when repaired correctly in conjunction with weight loss. For example, hiatal hernia recurrence rates after repair combined with bariatric surgery have been reported, with some studies indicating rates over 30%. Long-term follow-up care with both the bariatric surgeon and, if necessary, a hernia specialist is important to monitor for any signs of recurrence. Lifestyle adjustments, including maintaining a healthy weight through diet and exercise, also contribute to long-term success and help minimize the risk of hernia complications.
