Necrotising fasciitis after laparoscopic rectal cancer surgery

A rare case of pseudoaneurysmal hemorrhage, necrotizing fasciitis, and costochondritis after pancreaticoduodenectomy

BACKGROUND

Necrotizing fasciitis after pancreaticoduodenectomy (PD) has never been reported. We experienced a case of necrotizing fasciitis caused by pseudoaneurysmal hemorrhage after PD.

CASE PRESENTATION

A 72-year-old male was diagnosed with cholangiocarcinoma and underwent PD. Bile leakage was detected postoperatively, conservatively resolved, and the patient was discharged on the 36th day after surgery. On the 42nd day after surgery, a pseudoaneurysm of the gastroduodenal artery ruptured. Transcatheter arterial embolization was performed for hemostasis: however, a large intra-abdominal abscess caused by an infected hematoma was recognized. On the 57th day after surgery, the patient developed necrotizing fasciitis. He underwent debridement with skin reconstruction using a latissimus dorsi flap and skin transplantation. Costochondritis and liver metastasis were detected on the 267th day after surgery. Infection was controlled by rib cartilage resection, debridement, and negative pressure wound therapy. Chemotherapy involving gemcitabine and cisplatin was initiated on the 460th day after the initial surgery with a partial response (PR) and was continued for more than one year.

CONCLUSIONS

We herein reported a rare case of necrotizing fasciitis following hematoma infection after PD that was treated using multidisciplinary therapy with PR following chemotherapy.

Necrotizing Fasciitis of the Thigh as Unusual Colonoscopic Polypectomy Complication: Review of the Literature with Case Presentation

Necrotizing fasciitis (NF) is an infection characterized by necrosis of the superficial muscle fascia and surrounding soft tissues. It usually occurs following skin breaches from penetrating traumas or high-degree burns. Less frequently, it could be related to major abdominal surgery. However, no cases of thigh NF after minor abdominal procedures have ever been reported. A previously healthy 59-year-old male patient underwent a colonoscopic polypectomy. After the procedure, the patient developed an increasing right groin pain. The CT scan showed a gas collection in the right retroperitoneum space and in the right thigh soft tissues. Thus, a right colon perforation was hypothesized, and the patient was moved to the nearest surgery department and underwent a right hemicolectomy procedure. During surgery, the right thigh was also incised and drained, with gas and pus leakage. Nevertheless, the right lower limb continued to swell, and signs of systemic infection appeared. Afterward, clinical conditions continued to worsen despite the drainage of the thigh and antibiotic therapy, and the patient died of septic shock after just two days. This case shows that, although rare, lower limb NF should be considered among the causes of early post-operative local painful symptoms.
