It was reported that an erbe system, argon plasma coagulator (apc)/electrosurgical unit [esu/generator, model vio 3, part number (p/n) 10160-000, serial number (s/n) (b)(6)] system with a waterjet model erbejet 2 (p/n 10150-000, s/n (b)(6)) were involved in a patient incident after a gastric mucosa ablation (gma) as part of an hybridapc obesity study.The equipment was used with a hybridapc probe [p/n 20150-015, lot number (l/n) wo403073], waterjet pump cartridge (p/n 20150-301, l/n wo409593), and neutral electrode (nessy® plate 170, p/n 20193-074, l/n 210621-2401).The accessories were discarded after the procedure; therefore, they were not available for an examination.Approximately one (1) week after the gma treatment/procedure, the patient had upper gastrointestinal bleeding with melena and hematemesis as well as abdominal pain due to the formation of an ulcer.Then, the patient was admitted to the hospital for observation and treated with various medications (including acidblocking medication).The patient was discharged four (4) days later.No surgery was performed due to the bleeding.

The apc/esu system with the waterjet were thoroughly inspected/tested by rymed.A technical safety check was performed on each unit.This included an electrical safety check, a functional check of each of the equipment's features, and a power output check.Also, the gas flow rates were measured and found to be within their acceptable ranges for the apc.All features were/are functioning properly within specifications on the devices.Additionally, no anomalies were found in the device history records for the equipment or the hybridapc probe.In conclusion, no erbe equipment problem was found that would have caused or contributed to the event.Per the study protocol, ulcer formation with bleeding is considered as an anticipated adverse device effect (ade) associated with gma.Erbe usa, inc.Is now closing the file on this event.
