Background

Elizabeth and Ben Hanawa sued Dr. Nolan Perez and Gastroenterology Consultants of South Texas, PLLC, alleging that Elizabeth suffered serious injuries after Dr. Perez performed an endoscopic retrograde cholangiopancreatography. Elizabeth developed abdominal distension, nausea, vomiting, and pain after the procedure. A non-contrast CT indicated a likely walled-off duodenal perforation, but no repeat scan was performed, and a surgical consultation was not requested until approximately twenty-four hours after her symptoms began. Exploratory surgery ultimately revealed perforations and bilious spillage. Elizabeth developed sepsis and septic shock, and some of her organs did not fully recover.

In an earlier appeal, the court held that the Hanawas’ expert report did not adequately explain causation or foreseeability and remanded to permit an amended report. Gastroenterologist Dr. Kenneth Vega then submitted an amended report opining that Dr. Perez should have ordered a CT with contrast, immediately consulted a surgeon, and continued monitoring Elizabeth rather than referring her to family medicine. The trial court nevertheless found the amended report deficient, dismissed the claims with prejudice, and prompted this interlocutory appeal.

The Court’s Holding

The court held that Dr. Vega’s amended report adequately explained proximate causation under Texas Civil Practice and Remedies Code § 74.351. Read as a whole, the report linked Dr. Perez’s failure to order a contrast-enhanced CT to the failure to detect the perforation’s location and severity, which led to conservative treatment and delayed surgical repair. That delay allowed microorganisms to enter or accumulate in Elizabeth’s abdominal cavity, causing sepsis, septic shock, and organ damage.

The report also adequately addressed foreseeability by explaining that delaying diagnosis and repair of a duodenal perforation predictably increases the opportunity for infection and progression to life-threatening sepsis. Although the defendants argued that an earlier consultation might not have produced immediate surgery, the court concluded that the report sufficiently explained how proper imaging would have revealed the need for emergency treatment and changed Elizabeth’s care. The trial court therefore abused its discretion by sustaining the objections and dismissing the suit. The appellate court reversed and remanded for further proceedings.

Key Takeaways

  • A Chapter 74 expert report must connect the alleged breach to the claimed injury, but it need not prove the claimant’s case at the preliminary report stage.
  • An expert may establish causation by explaining how omitted diagnostic testing would have revealed a condition, changed treatment, and prevented or reduced the resulting harm.
  • Courts evaluate causation and foreseeability by reading the expert report as a whole rather than isolating individual statements as conclusory.

Why It Matters

The decision illustrates the level of detail needed to cure a deficient medical-malpractice expert report in Texas. A report can survive dismissal when it supplies a coherent clinical sequence connecting inadequate diagnostic testing and delayed intervention to infection and resulting injuries.

The ruling does not decide whether Dr. Perez was negligent or ultimately liable. It holds only that the amended report made a good-faith effort to address the statutory elements, allowing the Hanawas’ claims to proceed in the trial court.
