Two Cases of Mallory-Weiss Syndrome During Bowel Preparation for Colonoscopy / 대한소화기내시경학회지

Polyethylene glycol solutions have been usually available for clinical use since 1980 and been considered a standard method of bowel preparations for colonoscopy. There have been many reports about minor complications such as nausea and bloating associated with their use, which are frequently occurred. After ingestion of polyethylene glycol, vomiting occurrs less frequently but it can make major complication such as Mallory-Weiss syndrome and aspiration pneumonia. We have reported here two cases of Mallory-Weiss syndrome, which were occurred after ingestion of polyethylene glycol solution for colonoscopy.

Venous thrombosis associated with psoas abscess: successful treatment with percutaneous drainage of abscess and antibiotics / 대한내과학회지

We report an unusual case of venous thrombosis complicated by pyogenic psoas muscle abscess in a patient with chronic biliary tract disease. A 64-year-old woman presented with high fever and progressive back and left flank pain. She had been admitted because of recurrent cholangitis and liver abscess 7 months ago. Both abscess and blood cultures had revealed Klebsiella pneumoniae and she had improved with treatment of antibiotics and percutaneous drainage of abscess. Computed tomography demonstrated psoas abscess and thrombosis of inferior vena cava and left iliac vein adjacent to abscess. Several days later, abscess culture showed Klebsiella pneumoniae. Because there was no evidence of deep vein thrombosis and the thrombosis was confined only to the vein adjacent to the abscess, we considered that the thrombosis would be associated with the abscess. She was immediately treated with percutaneous drainage of abscess and antibiotics. Follow-up computed tomography demonstrated complete disappearance of both psoas abscess and venous thrombosis.

Development of ARDS by Hemothorax as a Complication of Subclavian Catheter Insertion / 대한신장학회잡지

Subclavian catheters were used in the treatment of chronic renal failure patients waiting for the maturation of AV fistula. But, it sometimes causes fatal complications. Of these, massive bleeding into pleural cavity after subclavian vein cannulation is a rather rare but causes very serious complication. Most of patients with hemothorax are successfully treated with conservative treatment(i.e. pleural drainage, maintaining the circulatory volume, treatment of possible coagulopathy) but it sometimes needs surgery. We recently experienced a case of ARDS complicated by hemothorax which was successfully treated with thracooscopic drainage. We reviewed the pathogenesis of ARDS by hemothorax and suggested the guidlines for the treatment of massive hemothorax using video-assisted thoracoscopic surgery.

Retroperitoneal Abscess by Citrobacter and Klebsiella in a Renal Transpant Recipient / 대한이식학회지

Infectious complications are common causes of morbidity in renal transplant recipients. To date, only two cases of retroperitoneal abscess caused by Norcardia asteroides and Mycobacterium fortuitum were reported in renal transplant recipients in the literature. We report a case of retroperitoneal abscess caused by gram negative bacilli-Citrobacter freundi, Klebsiella pneumoniae. The patient was admitted to the hospital due to flank pain. Abdominal CT scan and CT scan-guided aspiration confirmed retroperitoneal abscess. It is likely that the abscess in our patient was related to the anti-rejection treatment which included high-dose steroids, and mycophenolate mofetil. To our knowledge, this is the first report of retroperitoneal absces caused by gram-negative bacilli.
