A Healthcare Focused Law Firm
When a colorectal surgeon, a specialist trained to treat conditions of the colon, rectum, and anus, causes harm through a preventable mistake, the physical and emotional consequences can be severe. You may be dealing with a painful recovery, an unexpected second surgery, or a diagnosis that was missed entirely. These situations raise difficult questions, and getting clear answers can feel overwhelming.
At Hastings Law Firm, we focus exclusively on medical malpractice. Our legal and medical team, including in-house nurse consultants and former defense attorneys, understands both the clinical details and the legal strategy required for these cases. As an experienced Arizona colorectal surgeon malpractice lawyer team, we are prepared to investigate what happened, identify where the standard of care broke down, and hold the responsible parties accountable.
If you believe you or a loved one was harmed during colorectal treatment, we can review the details of your situation and explain your options during a free, confidential evaluation.
Common Errors Committed by Arizona Colorectal Surgeons
Colorectal malpractice occurs when a surgeon deviates from the accepted standard of care, resulting in errors such as bowel perforation, failure to diagnose cancer, or surgical site infections. Proving malpractice requires identifying exactly where a surgeon’s actions fell below the accepted standard of care. These cases often involve technically demanding procedures like a colonoscopy or sigmoidoscopy where even small missteps can lead to life-altering complications.
Surgical Complications
One of the most serious risks is bowel perforation, an injury where a surgical instrument punctures or nicks the wall of the intestine or a nearby organ. If the surgeon does not recognize and repair the damage during the procedure, intestinal contents can leak into the abdominal cavity. That leak can trigger sepsis, a dangerous, body-wide infection that occurs when the immune system’s response to an infection begins damaging the patient’s own organs. Untreated sepsis can be fatal.
Patients also frequently face surgical site infections. While some infection risk is inherent in any procedure, negligence in sterile technique, wound care, or post-operative monitoring can turn a manageable risk into a prolonged and painful ordeal.
Procedural Errors
Surgeons may make mistakes during specific colorectal procedures, including:
- Hemorrhoidectomies where excessive tissue removal or improper technique causes chronic pain, incontinence, or anal stenosis.
- Bowel resections for diverticulitis where the surgeon removes too much or too little tissue, or fails to ensure a secure anastomosis (the reconnection of the bowel).
- Surgeries related to Crohn’s disease or inflammatory bowel disease where operating on the wrong segment of bowel or failing to account for disease progression leads to preventable complications.
Anesthesia Errors
A lesser-known but deeply traumatic form of malpractice is anesthesia awareness, a condition where a patient regains consciousness during surgery but remains physically paralyzed by the anesthetic agents. The patient may feel pain, pressure, or hear conversations but cannot move or alert anyone. According to the Pennsylvania Patient Safety Authority, anesthesia awareness can cause lasting psychological harm and may constitute medical negligence when caused by dosing errors.
An Arizona colorectal surgeon malpractice lawyer can help determine whether complications like these resulted from an unavoidable surgical risk or a preventable breach of the standard of care.
Missed Diagnosis of Colon Cancer and Polyps
One of the most consequential forms of colorectal malpractice involves the failure to identify or properly evaluate suspicious tissue. Timely diagnosis is critical because early-stage colorectal cancer is often highly treatable. During a colonoscopy, a procedure in which a flexible camera is guided through the colon to examine its lining, a physician may encounter polyps or abnormal growths. The standard of care typically requires that these findings be removed or sampled through a biopsy, a small tissue sample sent to a pathology lab for microscopic analysis.
Errors at this stage can be devastating. A polyp that is overlooked, incompletely removed, or not sent for biopsy may be a malignant tumor, and without timely intervention, the cancer can progress to metastasis, spreading to the lymph nodes or distant organs.
Age-based bias also contributes to delayed diagnoses. Younger patients who present with symptoms like rectal bleeding, unexplained weight loss, or changes in bowel habits are sometimes dismissed because colon cancer has historically been considered an “older person’s disease.” When a physician fails to order appropriate diagnostic tests based on assumptions about age rather than clinical evidence, that delay can cost the patient critical treatment time.

Proving the Standard of Care Was Breached
To win a malpractice claim, a plaintiff must prove the existence of a doctor-patient relationship, establish the medical standard of care, demonstrate how the surgeon breached that standard, and directly link that breach to the specific injury or damages suffered. Establishing negligence involves comparing a surgeon’s actions to the medical standard of care found in similar clinical settings. Each element requires supporting evidence, and the burden of proof rests with the patient.
Defining the Standard
The standard of care refers to the level of treatment a reasonably competent colorectal surgeon would have provided under similar circumstances. This is not measured by perfection. It is measured by what a qualified peer would have done given the same clinical information. Arizona Revised Statutes § 12-563 outlines the necessary elements of proof a patient must establish in a medical malpractice action.
The Role of Expert Witnesses
Arizona law requires expert testimony to establish what the standard of care was and how it was violated. A qualified expert witness, typically a practicing colorectal surgeon or relevant specialist, must review the case records and offer opinions on both the breach and its consequences. Our team works with a national network of top-tier medical experts who can speak with authority on surgical technique, post-operative protocols, and clinical decision-making.
Causation
Proving the breach alone is not enough. The patient must also demonstrate that the error directly caused the harm and meet the legal burden of proof required by the court. For example, if a surgeon perforated the bowel during a procedure and the patient now requires a permanent colostomy, the connection between the mistake and the outcome must be clearly established. This often involves detailed review of the pathology report, the tissue analysis that identifies disease type and progression, to determine if metastasis, the spread of cancer to other body parts, occurred due to delay.
Our Arizona colorectal surgeon malpractice lawyers examine every available record, from pre-operative assessments to post-surgical nursing notes, to build a clear timeline of what happened and why.
A checklist of what we evaluate in these cases includes:
- Operative and anesthesia records
- Pre- and post-surgical imaging
- Pathology and biopsy reports
- Nursing notes and vital sign trends
- Informed consent documentation; this means your doctor explained the risks and you agreed to the treatment
- Expert opinions on surgical technique and decision-making
Liability of Multiple Parties
In many colorectal malpractice cases, fault does not rest with a single provider. Legal claims often involve multiple parties who shared responsibility for patient safety. The surgeon may bear primary responsibility, but the hospital can also be liable for issues like inadequate staffing, faulty equipment, or failure to enforce safety protocols. Independent contractors, such as an anesthesiologist or pathologist who is not a hospital employee, may carry separate liability.
We investigate hospital negligence and apportioned fault to determine each party’s role and decide who should be held accountable.

Recoverable Damages in Colorectal Malpractice Lawsuits
Victims of colorectal negligence may recover compensation for economic losses like medical bills and lost wages, as well as non-economic damages for pain, suffering, and loss of quality of life. Compensation is designed to cover both the financial costs and the personal impact of a medical injury. The Arizona Constitution, Article 2, Section 31, protects the right of injured individuals to recover damages, and Arizona does not impose caps on compensatory awards in personal injury or wrongful death cases.
Economic vs. Non-Economic Damages
| Economic Damages | Non-Economic Damages |
|---|---|
| Past and future medical bills (corrective surgeries, ostomy supplies, ongoing care) | Physical pain and suffering |
| Lost wages and reduced earning capacity | Emotional distress |
| Rehabilitation and home care costs | Loss of consortium (impact on relationships) |
| Prescription medications and medical equipment | Permanent disability or disfigurement |
Economic damages cover measurable financial losses. If a patient now requires a colostomy, a surgically created opening in the abdomen for waste elimination, the long-term costs of supplies, follow-up procedures, and lifestyle modifications can be substantial. Lost wages account for both time already missed and future earning capacity that may be permanently reduced.
Non-economic damages address the personal toll of the injury. Chronic pain, the psychological impact of disfigurement, and the strain on family relationships are all recognized categories of loss under Arizona law. Families rely on this compensation to offset the profound lifestyle changes caused by malpractice. Patients coping with permanent disability or the emotional weight of a preventable injury find that financial recovery provides necessary stability.
Wrongful Death
When complications such as sepsis, an uncontrolled systemic infection, lead to a patient’s death, surviving family members may pursue a wrongful death claim. These cases can include damages for loss of financial support, funeral expenses, and the loss of companionship and guidance.
An Arizona colorectal surgeon malpractice lawyer at our firm can evaluate the full scope of your losses and work to ensure every category of damage is accounted for.

Frequently Asked Questions About Colorectal Surgeon Malpractice in Arizona

Key Colorectal Surgeon Malpractice Terms:
- Colorectal surgeon
- A medical doctor who specializes in diagnosing and surgically treating diseases and conditions of the colon, rectum, and anus. In malpractice cases, these surgeons may be held liable for errors during procedures like colonoscopies, bowel resections, or treatments for conditions such as cancer, diverticulitis, or Crohn’s disease.
- Bowel perforation
- A hole or tear in the wall of the intestine that allows digestive contents to leak into the abdominal cavity. This serious surgical complication can occur when a surgeon accidentally nicks or cuts the bowel during a procedure, potentially leading to infection, sepsis, or the need for additional emergency surgery.
- Anesthesia awareness
- A rare but traumatic event where a patient regains consciousness during surgery while under general anesthesia but remains paralyzed and unable to move or communicate. This can result in the patient feeling pain, pressure, or hearing conversations during the procedure, often causing severe psychological distress.
- Colonoscopy
- A medical procedure in which a flexible tube with a camera is inserted through the rectum to examine the inside of the colon and rectum. It is commonly used to screen for colon cancer and detect polyps. In malpractice cases, errors may include failure to identify cancerous growths or polyps, or causing injury such as bowel perforation during the procedure.
- Biopsy
- A medical procedure in which a small sample of tissue is removed from the body and examined under a microscope to check for disease, including cancer. In colorectal malpractice cases, errors can occur if a surgeon fails to take a biopsy of a suspicious area, or if the sample is mishandled or misdiagnosed by the pathology lab.
- Pathology report
- A detailed medical document prepared by a pathologist after examining tissue samples under a microscope. The report identifies whether cells are normal, precancerous, or cancerous. In malpractice cases, a misread or delayed pathology report can lead to missed or delayed cancer diagnoses, allowing the disease to progress and worsen the patient’s prognosis.
- Metastasis
- The spread of cancer from its original location to other parts of the body through the bloodstream or lymphatic system. In delayed diagnosis cases, proving that a cancer would not have metastasized if detected earlier is critical to establishing that the doctor’s negligence directly caused the patient’s worsened condition and need for more aggressive treatment.
- Sepsis
- A life-threatening medical emergency in which the body’s response to an infection causes widespread inflammation and can lead to tissue damage, organ failure, and death. In colorectal surgery cases, sepsis often results from untreated bowel perforations or leaks that allow bacteria to enter the bloodstream, and it may form the basis for wrongful death claims.
- Colostomy (ostomy)
- A surgical procedure that creates an opening in the abdomen through which part of the colon is brought to the surface, allowing waste to exit the body into an external bag. A colostomy may be temporary or permanent and is often necessary after severe bowel injuries or complications from surgery. In malpractice cases, the need for a permanent colostomy bag represents a significant life-altering injury that increases the value of non-economic damages.
