Endoscopic Treatment of Diverse Complications Caused by Laparoscopic Adjustable Gastric Banding: A Study in Eastern Asia

BACKGROUND/AIMS: The use of laparoscopic adjustable gastric banding (LAGB) is increasing proportionally with the obesity epidemic. However, some postoperative complications have been highlighted as major problems associated with LAGB. There is no consensus concerning the endoscopic management of these adverse events. The aim of this study was to retrospectively review the feasibility and effectiveness of endoscopic treatment for LAGB complications. METHODS: We retrospectively evaluated 352 patients who underwent LAGB between 2011 and 2015. LAGB-associated complications developed in 26 patients (7.4%). This study involved six patients (1.7%) who received endoscopic treatment. RESULTS: Types of LAGB-induced complications in our series included intragastric migration (n=3), gastric leaks (n=2), and gastric fistulas (n=1). The endoscopic treatment of these complications was successful in four of the six patients. Endoscopic band removal was successful in two patients. All gastric leaks were successfully closed via an endoscopic procedure. In two cases (intragastric migration and gastric fistula), endoscopic treatment was not sufficient, and surgery was performed. CONCLUSIONS: Endoscopic procedures afforded acceptable treatment of band migration and gastric leaks after LAGB. However, the results were poor in patients with gastric fistula.

A Case of Cameron Ulcer Presenting with Melena / 대한내과학회지

Cameron ulcers are gastric ulcers or erosions located at mucosal folds in patients with large hiatal hernias. Mechanical trauma, gastric acid injury, or ischemia can cause their formation. Cameron ulcers are frequently seen as incidental findings during upper gastrointestinal endoscopy. About half of patients with these lesions are asymptomatic. However, Cameron ulcers are related to iron deficiency anemia and gastrointestinal bleeding in some cases. Here, we report a case of Cameron ulcers presenting with melena, which was successfully treated with proton pump inhibitors and iron supplementation.

A Case of Primary Hyperparathyroidism Caused by Solitary Parathyroid Adenoma That was Not Detected by Both Ultrasonography and Sestamibi Scan

Thanks to advances in assay techniques and routine measurements in serum chemical analysis, primary hyperparathyroidism has become far more frequently detected, and the number of asymptomatic patients has substantially increased. In the majority of patients (85%), a solitary adenoma is the underlying cause of primary hyperparathyroidism. Surgical excision is the treatment of choice for most cases of primary hyperparathyroidism; this procedure has a relatively high success rate. In the past decade, improvements in preoperative imaging have played a major role in a targeted operative approach, which allows for minimally invasive surgery to be performed. The success of parathyroid surgery depends on the accurate preoperative localization of parathyroid adenoma. In this study, we report the case of a 54 year-old woman with primary hyperparathyroidism who presented with left buttock and leg pain. For localization of the parathyroid lesion, an ultrasonography and a 99mTc-sestamibi scan were initially performed, but these attempts failed to localize the lesion. We then carried out contrast-enhanced CT; thereafter, a single parathyroid adenoma was detected. Therefore, in patients with negative results on both ultrasonography and 99mTc-sestamibi scan, contrast-enhanced CT may prove helpful for preoperative parathyroid localization.

A Case of Endocarditis due to Granulicatella adiacens / 감염과화학요법

Granulicatella species are nutritionally variant streptococci first described in 1961. Granulicatella species form a part of the normal flora of the oral cavity, genitourinary tract, and intestinal tract. These micro-organisms cause bacteremia or local infections such as endocarditis, central nervous system infections, arthritis, and osteomyelitis. Since isolation of Granulicatella species is difficult, only a few cases of infection caused by this microorganism have been reported. Herein, we report a case of endocarditis caused by Granulicatella adiacens in a 46-year-old patient with ventricular septal defect.

Kaposi's Sarcoma in a Patient on Hemodialysis / 대한신장학회지

Kaposi's sarcoma (KS) is an unusual multifocal neoplasm of vascular endothelial cell origin. The trunk, arms, head, and neck are the most common sites. It is common in men and has four distinct variants: classic, Africa-endemic, immunosuppressive drug-associated, and acquired immunodeficiency syndrome-associated KS. KS appears to develop immunosuppressed patients, but is uncommon in patients on dialysis. A 79-year-old man on hemodialysis for 2 months presented with pruritus over the entire body and multiple, discrete, variable-sized, dark blue papulonodules (papuloplaques, maculopapules) on the left arm and shoulder. A biopsy specimen form the left arm showed spindle cells with slit-like spaces and extravasated red blood cells. The specimen was positive for CD 34 antigen, and human herpesvirus 8 was detected. We report a case of KS that occurred in a 79-year-old patient on hemodialysis.

A Case of a Successful Band Ligation of a Colonic Perforation during Diagnostic Colonoscopy / 대한소화기내시경학회지

Colonoscopy is a relatively safe tool for diagnosis and treatment of colorectal disease. But colonic perforation during colonoscopy is a severe complication and sometimes becomes a life-threatening condition. It occurs with a frequency of 0.07% among patients having diagnostic colonoscopy and in up to 0.40% of patients having therapeutic colonoscopy. In these cases, surgical treatment is needed but endoscopic repair and conservative management could reduce the need for immediate operations. Endoscopic clipping has been the principal method for non-operative treatment of iatrogenic colonic perforation, but it has important limitations. One of them is that it is technically difficult to clip when the angle of approach is tangential. Here we report a case of an iatrogenic colonic perforation treated with endoscopic band ligation rather than endoscopic clipping, because of approach difficulties.
