Bariatric Surgery Malpractice: Risks, Causes, And Legal Remedies

The Rise Of Bariatric Surgery

Obesity is a growing health crisis, and bariatric surgery has become one of the most common and effective treatments for severe obesity. Procedures like gastric bypass, sleeve gastrectomy, and adjustable gastric banding help patients lose weight, improve overall health, and reduce risks of diabetes and heart disease.

In the U.S., over 250,000 bariatric surgeries are performed annually, according to the American Society for Metabolic and Bariatric Surgery (ASMBS). While these procedures can be life-changing, they also carry significant risks—and when errors result from negligence, the outcomes are devastating.

Why Bariatric Surgery Malpractice Matters

Bariatric surgery involves permanent alterations to the digestive system. Small errors can lead to catastrophic complications such as internal bleeding, organ perforation, or sepsis. Patients trust their surgeons to adhere to strict standards of care. When those standards are violated, patients may face life-altering injuries or wrongful death.

How Often Bariatric Surgery Errors Occur

Studies show that:

  • Serious complications occur in 4–10% of bariatric surgeries.
  • Leaks at staple lines (such as in gastric bypass or sleeve gastrectomy) occur in 1–5% of cases but can be fatal if not promptly treated.
  • Postoperative mortality rates range from 0.1–2%, with malpractice contributing to many preventable cases.
  • A 2019 ASMBS review noted that up to 50% of bariatric malpractice claims involve leaks or infections that were improperly recognized or treated.

Common Types Of Bariatric Surgery Malpractice

Errors in bariatric procedures may include:

  • Surgical errors: Staple line leaks, bowel perforation, or incorrect placement of bands.
  • Anesthesia errors: Mismanagement of high-risk obese patients under sedation.
  • Failure to monitor: Not recognizing postoperative leaks, bleeding, or clots.
  • Infections: From poor sterilization or inadequate wound care.
  • Wrong procedure or poor candidacy screening: Operating on patients who were not good candidates for bariatric surgery.
  • Negligent follow-up care: Inadequate nutritional guidance or monitoring for long-term complications. This includes failing to identify nutritional deficiencies (like Wernicke’s Encephalopathy) or a hernia/volvulus caused by the procedure.

Causes Of Bariatric Surgical Errors

Most malpractice stems from:

  • Inexperienced or inadequately trained surgeons.
  • Poor patient screening and lack of informed consent.
  • Rushed “assembly line” surgeries at high-volume centers.
  • Failure to convert from laparoscopic to open surgery when necessary.
  • Inadequate monitoring for leaks, infections, or embolisms.

Standard Of Care In Bariatric Procedures

The standard of care requires:

  • Thorough patient evaluation before surgery, including candidacy screening.
  • Informed consent detailing risks, alternatives, and realistic outcomes.
  • Proper surgical technique, including careful stapling and tissue handling.
  • Postoperative monitoring for leaks, infections, and embolisms.
  • Long-term follow-up care to address nutrition, weight management, and potential complications.

Deviation from these protocols can form the basis of a malpractice claim.

Medical Consequences Of Bariatric Surgery Malpractice

The impact of malpractice in bariatric surgery can be catastrophic:

  • Immediate harm: Internal bleeding, sepsis, or leaks.
  • Long-term harm: Malnutrition, chronic pain, hernias, or strictures.
  • Psychological harm: Depression or anxiety following botched procedures.
  • Wrongful death: From untreated leaks, embolisms, or infections.

Spoiler alert for those fortunate enough to be unaware - being involved in an automobile accident sucks. Having an attorney like Brian Snyder by your side throughout the process was a huge relief and helped me get through this difficult chapter in my life. Brian and his team fought hard to make me whole and I could not be more pleased with the outcome.

Brian Snyder, attorney, was the only one who took my case more than five years ago.  I could not find an attorney in the state of Texas.  I spoke to many of the attorneys and law firms throughout Texas. I told them my symptoms were swollen lymph nodes, early signs of a recurrent hernia on my left groin, and I was always in pain.  No attorney wanted to help me throughout the state of Texas.  Brian Snyder, attorney, took my case without any hesitation.  He knew right away what I was going through.  Cause of Brian Snyder, I was able to get a settlement payment for an XL mesh plug and onlay.  I truly recommend Brian Snyder if any person is experiencing a recurrent hernia or mesh problems.  I truly recommend him as an attorney to get you results.  I consider Brian Snyder very sneaky, intelligent, with a lot of experience, and a view of common sense. Brian Snyder was very patience and understanding with my case. Brian Snyder is a very bright attorney. I wholeheartedly recommend that you give him a call. I am happy with the settlement and on my way to view and relax by the ocean. Thank you, Brian Snyder, for your help.

One can't begin to convey the immense gratitude we have for David Wenner. We were fortunate to have his highly skilled counsel for our brother, Richard who was involved in a life changing accident through no fault of his own. The enormity of his immediate medical needs and placement in ICU for several months was more complicated with us living out of state. David and his paralegal Jen showed their humanity and compassion in helping us to navigate the insurance and legal issues while staying abreast of Richard's ever-changing condition. They allowed us to concentrate on his care and recovery which was a true blessing. Richard continues to make progress, and he is indebted to David for helping to ensure his care for the future. Thank you, David & Jen !
