Transoralgastric gastroscopic debridement for peripancreatic abscess: a special case report.

ABSTRACT

Transoralgastric debridement for pancreatic abscess is one of the successful applications of NOTES in clinical practice. We present a case report as follows a 71-year-old female was hospitalized due to acute biliary pancreatitis. Three weeks after onset, the secondary abdominal CT showed a peripancreatic abscess. A passageway between the gastric wall and the abscess was made with a high-frequency puncher under the guidance of an ultrasonic gastroscope and then a gastroscope was directly inserted into the abscess, and a large amount of solid necrotic tissue was taken out with foreign body forceps and snare under the direct vision of a gastroscope. Then a 8.5F double-J stent and a nasobiliary drainage tube were inserted. After three times of intra-abdominal abscess debridement and repeated rinsing with an antibiotic solution, abdominal CT revealed the intra-abdominal abscess nearly disappeared and the patient discharged from hospital.
