[Fissure syndrome of a gastrointestinal artery pseudoaneurysm in contact with a pseudocyst of the pancreas: rare, but serious complication of chronic pancreatitis]

Hemosuccus Pancreaticus and Obstructive Jaundice: Two Rare Complications of Chronic Pancreatitis Treated by Arterial Embolization

The formation of a peripancreatic pseudoaneurysm is a rare and serious complication of chronic pancreatitis. In this report, we present the case of a 56-year-old male with a history of alcohol-related chronic pancreatitis resulting in both hemosuccus pancreaticus and obstructive jaundice due to a pseudoaneurysm of the gastroduodenal artery that was treated successfully by angiographic coiling.

Treatment strategies for bleeding from gastroduodenal artery pseudoaneurysms complicating the course of chronic pancreatitis-A case series of 10 patients

We analyzed our experience with management of gastroduodenal artery (GDA) pseudoaneurysms associated with chronic pancreatitis using a multidisciplinary approach. We treated 10 patients with GDA pseudoaneurysms (all men, aged 24-62 year) who underwent treatment during April 1998 to December 2016. All had presented with recent hematemesis and/or melena. Hemodynamically, stable patients were initially subjected to transcatheter embolization or radiologically guided thrombin injection. Recurrence of bleeding within 48 h was taken as failure. Emergency surgery was done for hemodynamic instability and recurrent bleeding, and elective surgery was carried out as per specific indications. Ten interventional procedures were performed in nine patients, while one was directly subjected to surgery. Angioembolization was done in five patients (with success in four) and thrombin injection in five patients (including one with embolization failure; with success in three). Six patients underwent surgery, two on emergency basis, for hemodynamic instability and recurrent bleeding in one each, and four for definitive treatment of pancreatitis/associated complication. One patient died while the other nine survived and well with no recurrence of bleeding during follow up (6 months to 10 years). Management of GDA pseudoaneurysms requires a multidisciplinary approach. Pseudoaneurysms with narrow neck are suitable for thrombin injection while those with wide neck should be subjected to angioembolization. Emergency surgical treatment is reserved for non-surgical failures, and choice between trans-ductal or trans-cystic approach is based on the location of the aneurysm.

Laparoscopy-assisted open cystogastrostomy and pancreatic debridement for necrotizing pancreatitis (with video)

INTRODUCTION

Pancreatic pseudocysts and walled-off necrosis are well-known complications, described in 10% of cases of acute pancreatitis. Open cystogastrostomy is usually proposed after failure of minimally invasive drainage or in the presence of septic shock. The objective of this study was to evaluate the feasibility and efficacy of laparoscopy-assisted open cystogastrostomy for treatment of symptomatic pancreatic pseudocyst with pancreatic necrosis.

MATERIALS AND METHODS

Between January 2011 and October 2014, all patients with pseudocyst and pancreatic necrosis undergoing open cystogastrostomy were included. Surgical procedure was standardized. The primary efficacy endpoint was the feasibility and efficacy of laparoscopy-assisted open cystogastrostomy as treatment of symptomatic pancreatic pseudocyst. Secondary endpoints included demographic data, preoperative management, operative data, postoperative data and follow-up.

RESULTS

Laparoscopy-assisted open cystogastrostomy was performed in 11 patients [six men (54%)], with a median age of 61 years (45-84). Nine patients received preoperative radiological or endoscopic management. First-line open cystogastrostomy was performed in two cases. Median operating time was 190 min (110-240). There was one intraoperative complication related to injury of a branch of the superior mesenteric vein. There were no postoperative deaths and two postoperative complications (18%) including one major complication (postoperative bleeding). The median length of hospital stay after surgery was 16 days (7-35). The median follow-up was 10 months (2-45). One patient experienced recurrence during follow-up.

CONCLUSION

Open cystogastrostomy for necrotizing pancreatitis promotes adequate internal drainage with few postoperative complications and a short length of hospital stay. However, this technique must be performed very cautiously due to the risk of vascular injury which can be difficult to repair in the context of severe local inflammation related to pancreatic necrosis.
