Gastric outlet obstruction (GOO) is a disease that causes pyloric canal or duodenal atresia by various etiologies. It is mainly caused by malignancy or peptic ulcer and rarely caused by corrosive injury, gastric polyp, pyloric stenosis, bezoar, or biliary stone. We report a rare case of GOO due to unreported etiology. A 74-year-old male patient with medical history of hypertension, diabetes mellitus, and stroke came to the emergency medical center with a chief complaint of acute stomachache. On abdominal computed tomography, it was diagnosed as GOO due to gall bladder distension from acute cholecystitis. During conservative treatment and antibiotics administration, gastrofibroscopy and magnetic resonance cholangiopancreatography was performed to determine other etiologies; however, the final diagnosis was made as acute cholecystitis. After laparoscopic cholecystectomy, he was discharged without specific complications. On a pathology examination postoperation, there was no specific diagnosis, except for acute cholecystitis. Gastric outlet obstruction is caused by various etiologies, with the course of treatment being dependent on the specific etiology. We report a rare case of GOO caused by gall bladder distension due to acute cholecystitis. Various etiologies should be considered carefully to include even the rare etiologies for choosing the correct treatment.

PURPOSE: The aim of this study was to investigate the risk factors for conversion to conventional laparoscopic cholecystectomy (CLC) in single incision laparoscopic cholecystectomy (SILC) along with the proposal for procedure selection guidelines in treating patients with benign gallbladder (GB) diseases. METHODS: SILC was performed in 697 cases between April 2010 and July 2014. Seventeen cases (2.4%) underwent conversion to conventional LC. We compared these 2 groups and analyzed the risk factors for conversion to CLC. RESULTS: In univariate analysis, American Society of Anesthesiologist score > 3, preoperative percutaneous transhepatic GB drainage status and pathology (acute cholecystitis or GB empyema) were significant risk factors for conversion (P = 0.010, P = 0.019 and P < 0.001). In multivariate analysis, pathology (acute cholecystitis or GB empyema) was significant risk factors for conversion to CLC in SILC (P < 0.001). CONCLUSION: Although SILC is a feasible method for most patients with benign GB disease, CLC has to be considered in patients with acute cholecystitis or GB empyema because it is likely to result in inadequate visualization of the Calot's triangle and greater bleeding risk.

Biliary hamartoma and congenital hepatic fibrosis belong to fibrocystic disorders originating from ductal plate malformation. A 66-year-old man who had incidentally been diagnosed with biliary hamartoma two years ago presented to us with recurrent acute cholangitis. In the first episode, he had presented with septic shock and was treated with endoscopic retrograde cholangiopancreatography (ERCP) and cholecystectomy under the diagnosis of acute cholecystitis and cholangitis. However, during a two-month follow-up period, the patient experienced four episodes of acute cholangitis. Because he showed normal ERCP, and biliary hamartoma is usually asymptomatic, a liver biopsy was performed. Pathology revealed combined features of biliary hamartoma and congenital hepatic fibrosis, characterized as periportal fibrosis and intrahepatic ductular dysplasia. During follow-up for the last six months, he had experienced two episodes of acute cholangitis and was treated with antibiotics. A follow-up abdominal CT scan revealed aggravated hepatosplenomegaly compared to that of two years ago. We report a case of combined congenital hepatic fibrosis and biliary hamartoma and a literature review.

Portal vein thrombosis is an uncommon but an important cause of portal hypertension. The most common etiological factors of portal vein thrombosis are liver cirrhosis and malignancy. Albeit rare, portal vein thrombosis can also occur in the presence of local infection and inflammation such as pancreatitis or cholecystitis. A 52-year-old male was admitted because of general weakness and poor oral intake. He had an operation for colon cancer 18 months ago. However, colonic stent had to be inserted afterwards because stricture developed at anastomosis site. Computed tomography taken at admission revealed portal vein thrombosis and inflammation at colonic stent insertion site. Blood culture was positive for Escherichia coli. After antibiotic therapy, portal vein thrombosis resolved. Herein, we report a case of portal vein thrombosis with sepsis caused by inflammation at colonic stent insertion site which was successfully treated with antibiotics.

Mucosal-associated invariant T (MAIT) cells and natural killer T (NKT) cells are known to play crucial roles in a variety of diseases, including autoimmunity, infectious diseases, and cancers. However, little is known about the roles of these invariant T cells in acute cholecystitis. The purposes of this study were to examine the levels of MAIT cells and NKT cells in patients with acute cholecystitis and to investigate potential relationships between clinical parameters and these cell levels. Thirty patients with pathologically proven acute cholecystitis and 47 age- and sex-matched healthy controls were enrolled. Disease grades were classified according to the revised Tokyo guidelines (TG13) for the severity assessment for acute cholecystitis. Levels of MAIT and NKT cells in peripheral blood were measured by flow cytometry. Circulating MAIT and NKT cell numbers were significantly lower in acute cholecystitis patients than in healthy controls, and these deficiencies in MAIT cells and NKT cell numbers were associated with aging in acute cholecystitis patients. Notably, a reduction in NKT cell numbers was found to be associated with severe TG13 grade, death, and high blood urea nitrogen levels. The study shows numerical deficiencies of circulating MAIT and NKT cells and age-related decline of these invariant T cells. In addition, NKT cell deficiency was associated with acute cholecystitis severity and outcome. These findings provide an information regarding the monitoring of these changes in circulating MAIT and NKT cell numbers during the course of acute cholecystitis and predicting prognosis.

BACKGROUND/AIMS: Several studies have shown the usefulness of endoscopic nasogallbladder drainage (ENGBD) in patients with acute cholecystitis. However, the procedure is difficult, and factors that affect technical success have not yet been clarified. We conducted a prospective study to evaluate the technical feasibility, efficacy, and predictive factors for the technical success of ENGBD in patients with acute cholecystitis. METHODS: All patients with moderate or severe acute cholecystitis who were enrolled underwent ENGBD between April 2009 and April 2011. Patients with surgically altered anatomy or pancreatobiliary malignancies were excluded. The primary outcomes included technical success, clinical success, and complications. Factors that could affect the technical success were also examined. RESULTS: Of the 27 patients who underwent ENGBD during the study period, technical success was achieved in 21 (78%) and clinical improvement was achieved in 20 (95%). Early complications were encountered in four patients (15%). Gallbladder wall thickness (odds ratio [OR], 1.64; 95% confidence interval [CI], 1.08 to 2.47) and age (OR, 1.16; 95% CI, 1.00 to 1.35) were effective predictors of technical failure. CONCLUSIONS: ENGBD was effective in resolving acute cholecystitis; however, this modality was technically challenging and had a limited success rate. Because of technical difficulties, ENGBD should be reserved for limited indications.

Cholangitis and cholecystitis are intra-abdominal infections that show poor prognosis upon progression to sepsis and multiorgan failure. Administration of antibiotics with high antimicrobial susceptibility and removal of infected bile at the initial treatment are important. After undergoing ERCP for diagnostic purposes, a 58-year-old man developed acute cholangitis and cholecystitis accompanied by rhabdomyolysis, multi-organ failure, and severe sepsis. Broad-spectrum antibiotics with bedside endoscopic nasobiliary drainage were administered, but clinical symptoms did not improve. Therefore, bedside EUS-guided transgastric gallbladder aspiration and lavage was performed, resulting in successful treatment of the patient. We report the above described case along with a discussion of relevant literature.

BACKGROUND/AIMS: Early detection of gallbladder (GB) cancer is essential for better survival rates. Most cases of GB cancer are diagnosed incidentally via pathology of the cholecystectomy specimen. Data on the clinical characteristics of early GB cancer are lacking. The aim of the current study was to investigate the clinical characteristics of early GB cancer to aid earlier diagnosis. METHODS: Sixty-four patients who were diagnosed with early GB cancer after surgical resection at the Samsung Medical Center were enrolled in this study. Clinical characteristics, preoperative diagnoses, preoperative tumor size, laboratory findings including carbohydrate antigen 19-9 (CA19-9) levels, imaging features, and survival rate were investigated. RESULTS: Clinical symptoms and serum tumor markers such as carcinoembryonic antigen and CA19-9 levels were not helpful indicators of early GB cancer. Radiologic modalities showed abnormal findings in every case of early GB cancer; a polypoid mass was the most common feature. Less common features included GB wall thickening, cholecystitis, and GB stones. The clinical outcome of early GB cancer was excellent. CONCLUSIONS: Screening with imaging modalities such as computed tomography (CT) or ultrasonography (US) is helpful in detecting early GB cancer. Even in the presence of GB wall thickening, cholecystitis, or GB stones on the CT or US, any abnormal findings should prompt careful examination and intensive follow up, considering the possibility of occult gallbladder cancer.

PURPOSE: Single incision laparoscopic cholecystectomy (SILC) is a minimally invasive surgery that is growing rapidly among surgical procedures. However, there is no standard method for SILC. Therefore, we evaluated the adequacy and feasibility of SILC using Konyang Standard Method. METHODS: We retrospectively reviewed our series of 307 SILCs performed between April 2010 and August 2012. Initially we excluded the patients who were more than 70 years old, had cardiologic or pulmonologic problems and complications of acute cholecystitis. After 50 cases, we did not apply the exclusion criteria. We performed SILC by Konyang Standard Method using three-trocar single port (hand-made) and long articulated instruments. RESULTS: Three hundred and seven patients underwent SILC. Male were 131 patients and female were 176 patients. Mean age was 51.6 +/- 13.7 years old and mean body mass index was 24.8 +/- 3.6 kg/m2. Ninety-three patients had histories of previous abdominal operation. Patient's pathologies included: chronic cholecystitis (247 cases), acute cholecystitis (30 cases), gall bladder (GB) polyps (24 cases), and GB empyema (6 cases). Mean operating time was 53.1 +/- 25.4 minutes and mean hospital stay was 2.9 +/- 3.4 days. There were four cases of 3-4 ports conversion due to cystic artery bleeding. Complications occurred in 5 cases including wound infection (2 cases), bile duct injury (1 case), duodenal perforation (1 case), and umbilical hernia (1 case). CONCLUSION: SILC using Konyang Standard Method is safe and feasible. Therefore, our standard procedure can be applied to almost all benign GB disease.
