術後早期から高気圧酸素療法を施行したガス産生後腹膜膿瘍の1例(A case of gas–producing retroperitoneal abscess treated with hyperbaric oxygen therapy in the early postoperative period)

Key Points

• The aim was to assess the impact of hyperbaric oxygen therapy on recovery from a gas-producing retroperitoneal abscess after surgical intervention.
• A 79-year-old male diagnosed with a retroperitoneal abscess underwent urgent surgical drainage and was treated with antibiotics.
• Hyperbaric oxygen therapy was administered at 2 absolute atmospheres for 60 minutes daily for 10 days from the second postoperative day.
• CT-guided drainage was performed on the ninth postoperative day to target the remaining abscess.
• The abscess cavity disappeared following CT-guided drainage, indicating effective intervention.
• The patient's condition improved significantly, allowing for discharge on the 23rd postoperative day following independent ambulation.
