Hepatic artery pseudo-aneurysm rupturing into hepato-gastric fistula, a rare cause of massive upper gastrointestinal hemorrhage: Case report.

Hepatic artery pseudo-aneurysm and hepato-fastric fistula are extremely rare clinical entities, which can be caused as complications of amoebic liver abscess. Herein, we report a 45- year old man, who presented with history of hematemesis since last 1 day, melena since last 3 days and fever since last 5 days. On physical examination, he was hemodynamically stable, pallor was noted. Abdominal examination revealed tenderness over the right-upper quadrant. Per-rectal examination showed evidences of melena. Esophagogastroduodenoscopy revealed stomach communicating anteriorly with the abscess cavity from the surrounding, possibly from liver. There was no evidence of fresh bleed during the procedure. The abscess was drained and sent for microbiological evaluation. Computed tomographic angiography revealed a well defined saccular outpouching arising from common hepatic artery with surrounding ill-defined hypodensity around segment V and IVb of liver. Patient underwent transfemoral endovascular coil embolization. Post embolisation, DSA showed complete occlusion of pseudo-aneurysm. He was discharged on oral metronidazole and was doing well on 8-month follow-up with no episodes of rebleed.

Peripancreatic arterial pseudoaneurysm in the background of chronic pancreatitis: clinical profile, management, and outcome.

BACKGROUND: Bleeding pseudoaneurysm (PSA) is a rare but potentially lethal complication of chronic pancreatitis (CP). It requires expeditious management by a multidisciplinary team. The study aims to report our experience with PSA in the background of CP. METHODS: All the patients, who underwent intervention for CP-related PSA between August 2007 and December 2020 in the Department of Surgical gastroenterology, Institute of Postgraduate Medical Education and Research, Kolkata, India were retrospectively reviewed. RESULTS: Of the total 26 patients, 25 (96%) were men with a median age of 38 (11-63) years. The most commonly involved vessel was the splenic artery (n = 18, 69%). The interval between onset of GI bleed and intervention was 7 (0-120) days. Embolization was attempted in 11(42%) patients and was successful in six patients. Surgery was performed in 20 (77%) patients including five patients after failed embolization. The most commonly performed operation was distal pancreatectomy with splenectomy. The median operating time was 216 (115-313) minutes. The median intraoperative blood loss was 325 (100-1000) ml. Seventeen (85%) patients' required intraoperative blood transfusion. Four patients in the embolization group and five patients in the surgical group developed procedure-related complications. The most common postoperative complication was wound infection followed by pancreatic fistula. There was no procedure-related death. Over a median follow-up of 24 (6-122) months, no patient developed recurrent hemorrhage. CONCLUSIONS: Both embolization and surgery play an important role in the management of PSA. The choice of procedure depends upon the local availability and feasibility of a particular technique.

Macrodystrophia Lipomatosa: A Rare Cause of Bilateral Lower Limb Gigantism.

Macrodystrophia lipomatosa (MDL) is a rare congenital overgrowth syndrome characterised by inadvertent proliferation of all the mesenchymal elements resulting in localised gigantism. Herein, we present an eight-month-old female child, who presented to us with a history of gradual enlargement of both lower limbs along with the toes which was noticed by the parents a few days after birth. There was no history of trauma, pain or skin changes. Physical examination revealed unusual hypertrophy of both feet and toes. It was non-tender with no evidence of oedema or bruit over the swelling. X-ray of lower limbs revealed bony hypertrophy and overgrowth of all the bones with increased soft tissue shadow of bilateral foot. On ultrasound evaluation of the lower limbs, there was increased soft tissue in both dorsal and plantar aspect of bilateral foot without any vascular malformation. To characterise the swelling better, magnetic resonance imaging was warranted which revealed accumulation of excessive fat in the subcutaneous tissue without discernible capsule. Fibrous strand within the fat in bilateral feet, both in the plantar and dorsal aspect (more in plantar aspect), was seen. Core tissue biopsy was performed which showed abundant adipose tissue dispersed in mesh-like fibrous tissue and infiltrating the dermal connecting, suggestive of macrodystrophia lipomatosa. Currently, patient is advised for corrective surgery. Clinicians should be aware of these atypical presentations of MDL to differentiate it from other causes of local gigantism like fibrolipohamartoma (FLH) of nerve sheath, lymphangiomatosis, hemangiomatosis, Proteus syndrome, Klippel-Trenaunay syndrome and neurofibromatosis 1 as they differ in management and outcome.
