The Civil Police in Brazil are investigating the deaths of two patients after undergoing colonoscopy exams at a private clinic in Cerejeiras, Rondonia. The investigation aims to determine the circumstances surrounding their deaths, although there is currently no indication that the clinic or the responsible physician are directly implicated. Law enforcement officials have indicated that the outcome of the investigation will depend on the evidence gathered during the inquiry.

The patients in question include Thyago da Silva Severino, 34, who passed away in February this year following a colonoscopy, and Alzery Geraldo de Souza, 69, who died in September 2025 shortly after undergoing both colonoscopy and endoscopy procedures. These cases have sparked concern from family members, who have reported complications experienced by the patients after their medical procedures at the clinic.

This investigation raises important questions regarding patient safety and medical practices in private healthcare settings in Brazil. As the investigation unfolds, it could potentially lead to broader discussions about regulatory oversight, accountability, and the standards of care in the medical field, particularly regarding invasive procedures like colonoscopies, which are often conducted in outpatient facilities.
