Massive Duodenal Bleeding after the Migration of Endovascular Coils into the Small Bowel

Among gastrointestinal emergencies, acute upper gastrointestinal bleeding remains a challenging clinical problem owing to significant patient morbidity and costs involved in management. Endoscopic hemostatic therapy is the mainstay of treatment and decreases the incidence of re-bleeding, the need for surgery, morbidity, and mortality. However, in 8%–15% of patients with upper gastrointestinal bleeding, endoscopic hemostatic therapy does not successfully control bleeding. Trans-arterial coil embolization is an effective alternative treatment for endoscopic hemostatic failure; however, this procedure can induce adverse outcomes, such as non-target vessel occlusion, vessel dissection and perforation, and coil migration. Coil migration is rare but causes severe complications, such as re-bleeding and bowel ischemia. However, in most cases, coil migration is local and involves spontaneous healing without serious complications. Here, we report the case of a patient who underwent trans-arterial coil embolization of the gastroduodenal artery with the purpose of controlling massive duodenal bleeding, resulting in a fatal outcome caused by coil migration.

Idiopathic hypereosinophilic syndrome presenting with urinary frequency, abdominal pain, and diarrhea

Idiopathic hypereosinophilic syndrome (IHES) is a rare disorder defined by persistent blood eosinophilia, evidence of eosinophil-associated organ dysfunction and absence of secondary causes. Eosinophilic infiltration and its mediator release can cause damage to multiple organs. Although IHES can involve every organ system, bladder involvement is rarely evidenced. We recently reported a case of IHES with both bladder and gastrointestinal tract involvement. A 43-year-old woman visited Hallym University Sacred Heart Hospital complaining of urinary frequency, abdominal pain, and diarrhea for several months. Abdominal pelvic computed tomographic scan showed diffuse wall thickenings in her bladder and colon with small pelvic ascites. Laboratory investigation showed a marked peripheral eosinophilia and tissue biopsies confirmed eosinophilic infiltration in the bladder wall, esophagus, and duodenum. The patient was treated with prednisolone and her eosinophilia and symptoms have gradually improved.

Page kidney after botulinum toxin injection during chiropractic care / 영남의대학술지

Page kidney refers to the phenomenon of hypertension secondary to long-standing compression of renal parenchyma caused by renal subcapsular collection. The most common cause of renal subcapsular collection is a hematoma which usually occurs after a history of blunt trauma. A 42-year-old female patient who received botulinum toxin injection in her back during chiropractic care was admitted to the emergency room with sudden bilateral flank pain and hypertension. The computed tomography (CT) images demonstrated the presence of bilateral subcapsular renal hematoma. The patient was treated conservatively and recovered well. The follow up CT images showed markedly resolved bilateral hematoma.

Endoscopic Ultrasound-guided Drainage of Fluid Collection on Lesser Sac after Pancreaticoduodenectomy Not Accessible to Percutaneous Drainage / 대한췌담도학회지

Postoperative fluid collection is a major complication after pancreaticoduodenectomy and can lead to increased mortality and hospital length of stay. External drainage has widely been used for postoperative fluid collections. Recently, EUS-guided drainage has also been used successfully in treating postoperative fluid collections. A 60-year-old woman was admitted due to weight loss and jaundice. She underwent pancreaticoduodenectomy for cholangiocarcinoma of the common bile duct. After 2 weeks, she had fever with abdominal pain and leukocytosis. CT showed a increased fluid collection in superior recess of lesser sac and EUS-guided drainage was performed. The symptoms resolved without any complication after drainage. This is the first case report of EUS-guided drainage for lesser sac in Korea.

A Case of Intraductal Papillary Mucinous Neoplasm of the Pancreas with Pancreatoduodenal Fistula Diagnosed by Pancreatoscopy Using a Standard Upper Endoscope / 대한췌담도학회지

Intraductal papillary mucinous neoplasm of the pancreas (IPMN) is characterized by the production of mucin and marked dilatation of pancreatic duct. There are only several cases reports about fistula formation with adjacent organs in IPMN. A 61-year-old man was admitted due to jaundice and weight loss. CT scans showed that multiloculated cystic mass had replaced the body and tail of the pancreas. Interestingly, a fistula was found between cystic mass and duodenal bulb. With a diagnosis of malignant IPMN and pancreatoduodenal fistula, endoscopic forcep-biopsy was performed at the orifice of the fistula and pancreatic duct, through the fistula, under a fluoroscopic guidance. Pathologic examination showed only inflammatory cells. Direct peroral pancreatoscopy was performed through the pancreatoduodenal fistula using a standard upper endoscope with saline irrigation. Endoscopic forcep-biopsy was performed on the papillary tumor. Pathologic examination revealed intestinal type IPMN and radical total pancreatectomy was performed. Pathologic examination of the surgical specimen showed tubular adenocarcinoma arising from 15 cm sized intestinal type IPMN.

A Case of Hyponatraemic Seizure Following Terlipressin Therapy for a Variceal Hemorrhage in a Patient with Liver Cirrhosis / 대한내과학회지

Terlipressin has splanchnic vasoconstrictive effects, and is generally used for the management of gastroesophageal variceal bleeding secondary to liver cirrhosis. Terlipressin is a synthetic arginine vasopressin (AVP) analog containing a nonapeptide sequence. Terlipressin has increased selectivity for the V1 receptor, compared with AVP; hence, it is considered to be a safe vasoconstrictor. However, side effects such as hyponatremia and seizure, although very rare, have been reported. Hyponatremia related to terlipressin may be caused by the syndrome of inappropriate antidiuresis (SIAD), which is a disorder of sodium and water balance characterized by hypotonic hyponatremia without elevation of the antidiuretic hormone level. Here, we report a case of hyponatremic seizure induced by an infusion of terlipressin in a 52-year-old female who had isolated gastric variceal bleeding secondary to alcoholic liver cirrhosis.

A Case of Hepatitis B Virus Reactivation in a HBsAg-Negative and Anti-HBs-Positive Patient with Diffuse Large B-Cell Lymphoma after Rituximab plus CHOP Chemotherapy

The reactivation of hepatitis B virus (HBV) is well known complication among lymphoma patient related with chemotherapy. Rituximab is monoclonal antibody that targets B-lymphocytes for treatment of lymphoma and it increases reactivation of HBV. Although most of reactivation occurs in HBV carrier, it can also rarely occur when hepatitis B surface antigen (HBsAg) is negative. Furthermore it is less frequently reported in lymphoma patient when HBV serology shows HBsAg is negative and anti-HBs is positive. We report a case of HBV reactivation following 6 cycle of rituximab plus CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy for diffuse large B-cell lymphoma in HBsAg negative/anti-HBs positive 58-year-old male, with a review of the literature.
