Gastroenterology Experts
Board-certified physicians available to review cases and provide expert testimony in gastroenterology.
Gastroenterology Expert Witness Consulting
Gastroenterology claims cluster around two themes: procedural complications and diagnostic delay. Endoscopic procedures carry well-characterized risks — perforation, post-ERCP pancreatitis, bleeding — and missed or delayed GI cancer can convert a curable disease into a fatal one. In both, the technical detail of the procedure note and the adequacy of surveillance are central.
Our gastroenterologists and hepatologists actively perform the procedures at issue, including advanced-endoscopy physicians who regularly perform ERCP. They assess colonoscopy quality (preparation, withdrawal time, adenoma detection), surveillance intervals against published guidelines, and whether complications were recognized and managed in time.
Practice Areas
Our Gastroenterology specialists provide expert testimony across these core practice areas.
Endoscopy Complications
Perforation during EGD or colonoscopy, post-ERCP pancreatitis, bleeding complications, and preventability analysis.
Missed GI Cancer
Missed or delayed cancer diagnosis, inadequate surveillance, colonoscopy screening failures, and polyp management.
GI Bleeding Management
Acute upper and lower GI bleeding management, endoscopic intervention decisions, transfusion strategies, and shock management.
Inflammatory Bowel Disease
Crohn's disease and ulcerative colitis management, surgical timing, medication selection, and complication recognition.
Liver Disease
Cirrhosis diagnosis and management, hepatic encephalopathy, varices treatment, and liver failure management.
Medication-Related GI Injury
NSAID-related GI injury, aspirin and anticoagulant complications, and prophylaxis adequacy assessment.
Gastroenterology Cases We Handle
Attorneys retain our gastroenterology experts for matters including:
- Endoscopic perforation (EGD, colonoscopy) and delayed recognition of perforation
- Post-ERCP pancreatitis and duodenal perforation — risk stratification, prophylaxis, and management
- Missed or delayed colorectal and other GI cancers, including inadequate surveillance and lost-to-follow-up
- GI bleeding mismanagement — resuscitation, timing of endoscopy, and hemostasis
- Inflammatory bowel disease management and surgical-timing disputes
- Liver disease, cirrhosis, and transplant-hepatology management
- Medication-related GI injury (NSAIDs, anticoagulants) and prophylaxis adequacy
Questions Our Gastroenterology Experts Answer
Representative questions a gastroenterology expert can address on standard of care and causation:
Was the endoscopic procedure technically appropriate, and was a complication such as perforation recognized and managed in time?
For ERCP, were patient selection, indication, and pancreatitis prophylaxis consistent with the standard of care?
Was colonoscopy quality adequate — bowel prep, withdrawal time, inspection technique, adenoma detection?
Were surveillance intervals correct, and was the patient appropriately recalled for follow-up?
In a delayed-cancer case, what stage was the disease when it should have been detected versus when it was, and how does that change prognosis?
Was GI bleeding resuscitated and scoped within the appropriate window?
Daubert & Admissibility Considerations
Technical endoscopy opinions are most credible — and most defensible under Daubert — when the expert personally performs the specific procedure at high volume. We match cases accordingly (e.g., an ERCP-active physician for post-ERCP pancreatitis claims).
Delayed-cancer causation uses stage-shift and published survival data to quantify the harm caused by the delay, a reliable and widely accepted methodology rather than speculation about tumor behavior.
What to Expect When You Retain an Expert
Our process is built for litigation timelines — from conflict check to trial testimony.
1. Conflict check and intake
Send us the parties, the venue, and a short summary of the gastroenterology issue. We run a conflict check across our experts and confirm we can take the matter for your side, typically the same business day.
2. Expert match and fee schedule
We identify the board-certified gastroenterology expert whose subspecialty and active practice align with the specific clinical question, and provide that expert's CV and fee schedule — usually within one business day of a cleared conflict check.
3. Records review and preliminary merit assessment
The expert reviews the medical records, imaging, and relevant literature and gives you a candid preliminary read on standard of care and causation before you commit to a full written report. Expedited screening is available for discovery, deposition, and trial deadlines.
4. Written report and opinions
When the matter warrants it, the expert produces a signed report (or affidavit/declaration where required) setting out the standard of care, each identified deviation, and the causation analysis, supported by the records and published authority.
5. Deposition and trial testimony
The same expert is available for deposition and trial, with preparation sessions to ensure the opinions are communicated clearly and survive cross-examination and Daubert/Frye scrutiny.
