Experience of surgical management of pseudo-aneurysms of branches of the coeliac axis in a North Indian Hospital.

BACKGROUND: Bleeding splanchnic artery pseudo-aneurysm is a rare but frequently fatal complication that can be successfully managed by angiographic embolization. However, certain patients because of hemodynamic instability, non-availability of technique or angiographic failure may require primary surgical intervention. METHOD: Retrospective review of 13 patients presenting with exsanguinating hemorrhage from ruptured pseudo-aneurysm arising from branches of coeliac axis, managed surgically in absence of angiographic embolization. RESULTS: Splenic artery was most commonly involved (n = 7) followed by hepatic (n = 3), gastroduodenal (n = 2) and left gastric artery (n = 1). The most common underlying aetiology was pancreatitis (n = 8, acute = 2; chronic = 6) followed by iatrogenic (n = 3), liver abscess (n = 1) and gastric ulcer (n = 1). Seven patients presented with upper gastrointestinal (GI) bleed, while 2 each with lower GI bleed, haemobilia and bleeding through tube drains. CT-scan accurately demonstrated the pseudo-aneurysm in 11 (84.6%) patients and additionally demonstrated the underlying pathology. The surgical management chiefly consisted of ligation of offending vessel and additional procedures directed at primary pathology. Overall, 77% patients had a favourable outcome while 23% died consequent to ongoing hemorrhage. CONCLUSION: Pseudo-aneurysm involving the branches of coeliac axis most commonly arises as a result of pancreatitis and affects splenic artery. CT-scan accurately demonstrates pseudo-aneurysm and associated pathology in majority of cases. Primary surgical management in the presence of hemodynamic instability and non-availability of angiographic embolization is a viable alternative.

Symptomatic volvulus due to mid gut malrotation in an adult.

Anomalies of rotation and fixation of gut occur most commonly in the neonatal period and usually become symptomatic in infancy. We report an adult patient with symptomatic volvulus due to mid gut malrotation.

Duodenal villous adenoma.

Duodenal villous adenomas are extremely rare (1/5th of small bowel tumors). In view of their strategic position and risk of malignancy, they require definitive management in specialized care units. We report a case of a 35 year old female patient with a large duodenal (5 cm) villous adenoma causing intussusception of duodenum (a phenomenon rare because of its anatomic location & fixation).

Percutaneous catheter drainage in pancreatic pseudocysts.

Percutaneous catheter drainage (PCD) was performed in 12 pancreatic pseudocysts in 11 patients. The procedure was performed under realtime ultrasound guidance adopting a direct transperitoneal approach in all cases. Complete cure was achieved in 9 (75%) of the Pseudocysts drained. Success rate was higher in pseudocysts not communicating with the main pancreatic duct (MPD), 7 of 8 (87.5%) as compared to those with ductal communication, 2 of 4 (50%). The mean duration of catheter drainage was 14.2 days in the first group while it was significantly longer, (42.5 days) in the latter group. No death or major complication related to the procedure was encountered in the study. A single pseudocyst got infected after catheter insertion but it was treated successfully with antibiotics. The follow up period was 3-18 months with a mean of 6.8 months. PCD failed in 2 pseudocysts communicating with MPD and associated strictures in the MPD. In one case having no communication with MPD the procedure failed because the cyst had thick debris which could not be drained properly. PCD may be a safe and effective therapy in the management of pseudocysts with best results in those not communicating with the MPD. Communicating pseudocysts, also having strictures in MPD, should not be subjected to PCD.
