Gastrectomy for the treatment of refractory gastric ulceration after radioembolization with 90Y microspheres

Transcatheter arterial radioembolization (TARE) with Yttrium-90 (90Y)-labeled microspheres has an emerging role in treatment of patients with unresectable hepatocellular carcinoma. Although complication of TARE can be minimized by aggressive pre-evaluation angiography and preventive coiling of aberrant vessels, radioembolization-induced gastroduodenal ulcer can be irreversible and can be life-threatening. Treatment of radioembolization-induced gastric ulcer is challenging because there is a few reported cases and no consensus for management. We report a case of severe gastric ulceration with bleeding that eventually required surgery due to aberrant deposition of microspheres after TARE.

Spinal cord injury after conducting transcatheter arterial chemoembolization for costal metastasis of hepatocellular carcinoma

Transcatheter arterial chemoembolization (TACE) has been used widely to treat patients with unresectable hepatocellular carcinoma. However, this method can induce various adverse events caused by necrosis of the tumor itself or damage to nontumor tissues. In particular, neurologic side effects such as cerebral infarction and paraplegia, although rare, may cause severe sequelae and permanent disability. Detailed information regarding the treatment process and prognosis associated with this procedure is not yet available. We experienced a case of paraplegia that occurred after conducting TACE through the intercostal artery to treat hepatocellular carcinoma that had metastasized to the rib. In this case, TACE was attempted to relieve severe bone pain, which had persisted even after palliative radiotherapy. A sudden impairment of sensory and motor functions after TACE developed in the trunk below the level of the sternum and in both lower extremities. The patient subsequently received steroid pulse therapy along with supportive care and continuous rehabilitation. At the time of discharge the patient had recovered sufficiently to enable him to walk by himself, although some paresthesia and spasticity remained.

Optimal time for repeating the IgM anti-hepatitis A virus antibody test in acute hepatitis A patients with a negative initial test / 대한간학회지

BACKGROUND/AIMS: The nonspecific clinical presentation of acute hepatitis A (AHA) mandates the detection of anti-hepatitis A virus IgM antibodies (IgM anti-HAV) in the serum for obtaining a definitive diagnosis. However, IgM anti-HAV might not be present during the early phase of the disease. The aim of this study was to determine the optimal time for repeating the IgM anti-HAV test (HAV test) in AHA patients with a negative initial test. METHODS: In total, 261 patients hospitalized with AHA were enrolled for this retrospective study. AHA was diagnosed when the test for IgM anti-HAV was positive and the serum alanine aminotransferase (ALT) level was > or =400 IU/L. Repeat HAV test was conducted after 1-2 weeks if the initial HAV test was negative but AHA was still clinically suspected. RESULTS: The results of the initial HAV test were negative in 28 (10.7%) patients. The intervals from symptom onset to the initial-HAV-test day and from the peak-ALT day to the initial-HAV-test day were significantly shorter in the negative-initial-HAV-test group, but on multivariate analysis only the latter was significantly associated with negative results for the initial HAV test (beta=-0.978; odds ratio [95% confidence interval]=0.376 [0.189-0.747]; P=0.005). The HAV test was positive in all patients when it was performed at least 2 days after the peak-ALT day. CONCLUSIONS: The results of HAV tests were significantly associated with the interval from the peak-ALT day to the HAV-test day. The optimal time for repeating the HAV test in clinically suspicious AHA patients with a negative initial HAV test appears to be at least 2 days after the peak-ALT day.

Solitary Primary Gastric Mantle Cell Lymphoma

Mantle cell lymphoma (MCL) is a relatively rare subgroup of non-Hodgkin's lymphoma that is characterized by an aggressive and severe disease course with frequent involvement of regional lymph nodes and/or early metastasis. Because most cases of MCL are diagnosed in the advanced stages, clinical data on extranodal or early stage MCL is lacking, and MCL that is both extranodal and diagnosed during the early stages is even more rare. There have been several case reports on primary gastric MCL, which comprise a type of extranodal MCLs. However, to our knowledge, there have been no reports on solitary primary gastric MCL without regional lymph node involvement or distant metastasis. Recently, the authors experienced an uncommon case of MCL with the aforementioned characteristics that was managed with chemotherapy followed by allogenic stem cell transplantation.

Treatment Outcomes after Endoscopic Band Ligation of Symptomatic Internal Hemorrhoids / 대한내과학회지

BACKGROUND/AIMS: Elastic band ligation is a well-established method for the treatment of internal hemorrhoids. The aim of this study was to assess the treatment outcomes of flexible endoscopic rubber band ligation of internal hemorrhoids. METHODS: Using a flexible endoscope, 30 patients with symptomatic internal hemorrhoids were evaluated based on change in clinical symptoms (Goligher grade, bleeding score) and endoscopic classifications (range, size) before and after the procedure. RESULTS: Goligher grade and bleeding score showed significant improvement after the procedure (Goligher grade from 2.12 to 0.54, p<0.01, and bleeding score from 1.80 to 0.40, p<0.01). Endoscopic classification scores improved significantly after the procedure (range 3.03 to 1.55, p<0.01, and size from 1.80 to 0.85, p<0.01). As a complication, mild pain developed in 19 patients (90.5%) and severe pain in two patients (9.5%). Most (90.5%) were well controlled by conservative management, but one patient was operated on for hemorrhoidal thrombosis and in another patient the ligated rubber band had to be released promptly for pain relief. One patient (3.3%) experienced mild infection, which was relieved by medical treatment. During the 16.7+/-3.2-month period of follow-up, two patients relapsed, one was treated with additional endoscopic band ligation, and one underwent surgery. CONCLUSIONS: Flexible endoscopic band ligation is an effective and safe method of treatment in patients with symptomatic internal hemorrhoids.

Primary NK-/T- Cell Lymphoma of the Esophagus: a Case Presentation and Literature Review / 대한소화기내시경학회지

Extranodal natural killer/T-cell lymphoma (ENKL) is an uncommon neoplasm, and it is a subtype of non-Hodgkin's lymphoma. It most commonly presents in the nasal cavity and nasopharynx. But only 10% of ENKL may present on the skin or the gastrointestinal tract and this has a poor prognosis. We report here on a case of CD56+ NK/T-cell lymphoma that limited to the esophagus. A 55-year-old male patient presented with epigastric soreness. Esophagogastroduodenoscopy (EGD) showed well demarcated, longitudinal ulcerative lesions with an irregular base and a discrete margin on the lower esophagus. We performed EGDs and endoscopic biopsies 2 times, but these were insufficient to make a diagnosis. The 3rd time, we finally took a big piece of tissue using endoscopic mucosal resection with a cap-fitted panendoscope (EMR-C). The biopsies showed surface ulceration and a heavy lymphoid infiltration and a positive pattern for CD3, CD56 and granzyme B. The pathologic diagnosis was NK/T-cell lymphoma. The patient was treated with concurrent chemoradiation followed by additional chemotherapy and he achieved a complete response.

Two Cases of Incidentally Diagnosed Idiopathic Left Atrial Appendage Ostial Stenosis

We report here on 2 cases of idiopathic left atrial appendage ostial stenosis (LAA), and this rare finding was detected on transesophageal echocardiography. Its clinical implication is still unknown, given the small number of reported cases. Incompletely ligated LAA has characteristics similar to those observed in idiopathic LAA ostial stenosis, including the narrowed orifice, the small LAA cavity and the accelerated blood flow across the stenotic area. Since the incompletely ligated LAA has been reported to be complicated with thromboembolic events, we can assumed that the patients with idiopathic LAA ostial stenosis have a higher risk of thromboembolism than those with a normal LAA structure.

Prader-Willi Syndrome: A case report / 대한마취과학회지

The Prader-Willi syndrome (PWS) is a rare disorder characterized by infantile hypotonia, subsequent obesity with hyperphagia. Hypogonadism, cryptorchidism, delayed psychomotor development, short status, strabismus, myopia, scoliosis, kyphosis and temperature regulation abnormality are other features. The cause of this syndrome is unknown, but a disturbance in the hypothalamus has been postulated because of the various manifestation of the syndrome. The major genetic mechanism giving rise to PWS is a paternal deletion of about the same size in the 15q11-q13 region, that occurs in 70% of the cases. The principal problems related to anesthesia are those that are secondary to the patient's hypoglycemia, skeletal muscle hypotonia and obesity. An 20-month-old boy with PWS was scheduled for surgical correction of bilateral undescended testes. The trachea was intubated with the aid of succinylcholine 7.5 mg intravenous injection. Muscle relaxation was facilitated with intermittent intravenous administration of atracurium (total dose 8 mg). No prolonged effect of muscle relaxants was observed during anaesthesia. High grade fever (38-39 degrees C) was present during anaesthesia.

Effect of Local Warming of the Injection Site and Forearm on Propofol-Induced Pain / 대한마취과학회지

BACKGROUND: Propofol often causes pain when injected into small peripheral veins, but the pain can be minimized by using a larger vein. This study was designed to determine whether local warming of the injection site and forearm before propofol injection is effective in reducing pain. METHODS: Sixty adult patients undergoing general anesthesia for an elective surgery were randomly allocated to one of two groups. All were unpremedicated and had an 18-gauge cannula inserted into a cephalic vein on the wrist. Patients in group 1 (n = 30) received 1% propofol at room temperature. Patients in group 2 (n = 30) received 1% propofol after local warming (36-37 degrees C) of the injection site and forearm using a forced-air warming system (Bair Hugger(R)). For each patient, the pain during injection of the propofol solution was graded as none, mild, moderate, or severe. RESULTS: Overall the incidence of pain was significantly reduced in group 2 (36.7%) compared with group 1 (66.7%). No patients complained of pain at the injection site and forearm in group 2. However, there was no significant difference in the incidence or severity of pain on the elbow and axilla between the two groups. CONCLUSIONS: We found that local warming applied to the injection site (wrist) and forearm before propofol injection is significantly effective in reducing pain at the injection site and forearm, but there was no improvement of pain on the elbow and axilla when injecting.
