Lower gastrointestinal bleeding due to hepatic artery pseudoaneurysm following laparoscopic cholecystectomy

Abstract: Pseudoaneurysm of hepatic artery is a rare but known complication of laparoscopic cholecystectomy (LC). Such pseudoaneurysms may bleed in biliary tree, upper gastrointestinal (GI) tract or peritoneal cavity leading to life-threatening internal haemorrhage. It is very rare for them to present as lower GI bleeding. We report an unusual case of Right hepatic artery pseudoaneurysm developed following LC, which ruptured into hepatic flexure of colon resulting in catastrophic lower GI bleeding. This was associated w… Show more

“…Hepatic artery pseudoaneurysm (HAP) is a rare complication of liver injuries following blunt abdominal trauma (1)(2)(3). HAP rupture is the most dangerous and fatal obstacle, which usually presents itself as vague abdominal discomfort, gastrointestinal bleeding, and hemobilia (4)(5)(6). Although radiological intervention may prevent the need of aggressive treatments, mortality rate is still about 20% to 50% (7,8).…”

“…6 Failure may be due to the difficulty in approaching the PSA in the presence of a thrombosed proximal vessel, such as the coeliac or tortuous hepatic arteries. 5,11,24,36,48,55 In patients where cannulation is feasible, embolisation failure could be related to an inability to isolate the bleeding vessel, misidentification of the bleeding vessel or incomplete occlusion despite the disappearance of the sac or feeding vessel on post-embolisation angiography. 6,22 In addition, smaller vessels may feed the PSA and contribute to rebleeding, which may not be easily detected during angiography.…”

“…7 Erosion of a PSA into the cystic duct stump or GI tract forming a fistula between the two structures has been previously reported. 5,9,23,24,35,40 This could involve the duodenum, leading to haematemesis, the jejunum, for example in a patient presenting with lower GI bleeding who had previously undergone Roux-en-Y reconstruction following a stomach carcinoma, or hepatic flexure in a patient presenting with hematochezia. 23,24,35,40 In most patients (80%), the PSA usually presents approximately one month following the LC surgery; however, delayed PSA presentation as late as five years after the surgery has been reported.…”

“…Because it brings little damage and interference to internal organs and patients can recover quickly afterwards, LC has become the first operation choice for biliary tract diseases. However, the increased excitement of gastrointestinal sympathetic nerves, inhibited gastrointestinal function, and subsequent decreased gastrointestinal peristalsis and tension led by operation anesthesia, peritoneal stimulation, and traction during operation are possible to cause corresponding complications [4][5][6][7][8] . Therefore, it's of great significance to restore gastrointestinal function in promoting the post-operative recovery.…”
