The role of interventional radiology in the management of surgical complications after pancreatoduodenectomy.
ABSTRACT This study evaluates the role of interventional radiology (IR) in the management of postoperative complications after pancreatoduodenectomy (PD).
A total of 120 consecutive patients were reviewed to identify IR procedures performed for early complications after PD.
Findings showed that 24 patients (20.0%) required urgent radiological or surgical re-intervention for early complications, including 11 instances of post-pancreatectomy haemorrhage (PPH), six intra-abdominal abscesses, two bile leaks, one pancreatic fistula and one bowel ischaemia. Three of 24 complications were managed by surgery and 21 were managed by IR. Two of 11 PPHs involved intraluminal haemorrhage (ILH) and nine involved intra-abdominal haemorrhage (IAH). One ILH was managed conservatively and one required surgical intervention. In eight of nine patients with IAH, the bleeding site was identified on computed tomography angiography, and endovascular stenting or coil embolization were performed. No patient required a re-look laparotomy following IR for haemorrhage or intra-abdominal abscess. Overall, three of 120 patients required an urgent re-look laparotomy for early complications.
Rates of major morbidity after PD remain high. However, many significant complications (PPH, pancreatic fistula, intra-abdominal abscess) can be managed by IR, reducing the need for reoperation. Re-look surgery is still required in a small percentage (2.5%) of patients.

ABSTRACT: The mortality rate due to late hemorrhage after surgery for periampullary tumors is high, especially in patients with anastomotic leakage. Patients usually require emergency intervention for late hemorrhage. In this study patients with late hemorrhage and their outcomes were analyzed. Furthermore, independent predictors for late hemorrhage, the need for emergency intervention, and type of intervention are reported. From a prospective database that includes 1,035 patients who underwent pancreatoduodenectomy for periampullary tumors between 1992 and 2012, patients with late hemorrhage (>24 h after index operation) were identified. Patient, disease-specific, and operation characteristics, type of intervention, and outcomes were analyzed. Emergency intervention was defined as surgical or radiological intervention in hemodynamically unstable patients. Of the 47 patients (4.5 %) with late hemorrhage, pancreatic fistula was an independent predictor for developing late hemorrhage (OR 10.2). The mortality rate in patients with late hemorrhage was 13 % compared with 1.5 % in all patients without late hemorrhage. Twenty patients required emergency intervention; 80 % underwent primary radiological intervention and 20 % primary surgical intervention. Extraluminal location of the bleeding (OR 5.6) and occurrence of a sentinel bleed (OR 6.6) are indications for emergency intervention. The type of emergency intervention needed for late hemorrhage is unpredictable. Radiological intervention is preferred, but if it fails, immediate change to surgical treatment is mandatory. This can be difficult to manage but possible when both radiological and surgical interventions are in close proximity such as in a hybrid operating room and should be considered in the emergency management of patients with late hemorrhage.World Journal of Surgery 05/2014; · 2.23 Impact Factor

ABSTRACT: Despite improvements in surgical techniques and postoperative care, morbidity associated with pancreatoduodenectomy (PD) is still high. Grade B pancreatic fistula (PF) requires a specific combination of radiologically guided external drainage and medical support. This treatment is effective but requires prolonged hospitalization and maintenance of external drainage. The objective of this study was to evaluate the feasibility and efficacy of a double-pigtail stent (DPS) to treat grade B PF after PD with pancreatogastric anastomosis. Between January 2008 and October 2011, all patients who presented grade B PF after PD (n = 6) were included in the study. The PF was diagnosed according to the criteria of the International Study Group on Pancreatic Fistula. Endoscopic treatment was standardized with a DPS. The primary efficacy end point was the feasibility and efficacy of DPS placement. Secondary end points included data on the PF, the DPS placement procedure, and long-term outcome. Endoscopic DPS placement was achieved in all patients with no complications. The median time to onset of PF after PD was 14 days. Closure of the external PF was obtained 7 days after the introduction of the DPS. The median time to external drain removal was 7 days after DPS placement, and the median time to oral refeeding was 7 days after DPS placement for all patients. The median time to DPS removal was 60 days. The median length of hospital stay after DPS placement was 10 days. During a median follow-up period of 21 months, there was no recurrence of PF after removal of the DPS. Endoscopic treatment of grade B PF after PD appears to be effective and safe and is associated with shorter hospitalization.Surgical Endoscopy 12/2013; · 3.43 Impact Factor

ABSTRACT: Introduction Operative complications after pancreatoduodenectomy can be managed by nonoperative or operative interventions. The aim of this study was to analyze the shift in management of five major complications and their success rates. An algorithm was developed according to predictors for type of intervention and failure of management. Methods From 1992–2012, patients with pancreaticojejunostomy, hepaticojejunostomy or gastroenterostomy leakage, postpancreatectomy hemorrhage, or primary abscess after pancreatoduodenectomy were selected from a prospectively maintained database. Complications were treated by nonoperative or operative intervention Two cohorts were created according to period of index operation. Pre- and postoperative characteristics were analyzed. Results Of 1,037 patients, 263 (25%) experienced operative complications. The incidence of pancreatic fistula increased from 11 to 18%, accompanied by a shift from operative toward nonoperative management. This was also seen in the management of late hemorrhage. Success rates of interventions remained similar for all complications. The incidence of primary abscesses decreased. Early sepsis (odds ratio [OR] 17.8, 95% confidence interval [CI] 4.9–64.4) was associated with failure of nonoperative interventions in patients with pancreatic fistula. Hemodynamic instability (OR 17.2, 95% CI 1.8–160.1) and sepsis (OR 6.7, 95% CI 2.7–16.3) were predictive for operative intervention. Failure of nonoperative intervention (HR 3.95% CI 1.3–7.1) and operative intervention (HR 6.4 95% CI 3.2–12.8) were predictors for poor survival. Conclusion The shift towards nonoperative interventions was notable in patients suffering from pancreaticojejunostomy leakage and late hemorrhage. Anastomotic leakage, late hemorrhage, and primary abscesses can be managed nonoperatively however; hemodynamic instability and early sepsis are strong arguments to perform surgery.Surgery 01/2014; · 3.37 Impact Factor
