Background Internal drainage of giant pancreatic pseudocysts secondary to acute pancreatitis is frequently complicated with postoperative retroperitoneal infection and hemorrhage. Recent data suggest that the risk factor is unrecognized pancreatic necrosis; presumably, pancreatic necrosis becomes infected with bacteria introduced by the cystoenteric anastomosis.
Hypothesis Video-assisted pancreatic necrosectomy, performed at the time of internal drainage, may prevent postoperative retroperitoneal complications in patients with giant acute pseudocysts.
Design A consecutive case-series.
Setting An urban, university-affiliated, tertiary referral center.
Patients Ten consecutive patients with acute pseudocysts measuring 10 cm or more in major diameter. The mean extent of pancreatic necrosis, as shown by contrast-enhanced computed tomography, was 50%. All patients were operated on electively, at an average time of 7.7 weeks from onset of the attack to surgical treatment.
Intervention Through a midline incision, a 4-cm opening is made at the base of the pseudocyst. Standard laparoscopic instruments are introduced into the pseudocyst and video-assisted pancreatic necrosectomy is performed. The opening is then anastomosed to a Roux-en-Y limb of the jejunum.
Main Outcome Measures Feasibility and safety of video-assisted pancreatic necrosectomy, postoperative morbidity and mortality, hospital stay, and resolution of pseudocysts.
Results Complete necrosectomy was safely performed throughout. There were neither postoperative retroperitoneal complications nor mortality. Mean hospital stay was 8.2 days and all pseudocysts resolved at a mean follow-up of 6.9 months.
Conclusions Video-assisted pancreatic necrosectomy at the time of internal drainage seems to prevent postoperative retroperitoneal complications in patients with giant acute pseudocysts. Depending on appropriate surgical timing, video-assisted necrosectomy is a feasible and safe procedure.
