Endoscopic Treatment of the Zenker Diverticulum With Flexible Endoscopic Myotomy: A Single Tertiary Center Experience.

INTRODUCTION: The Zenker diverticulum (ZD) is the most common type of esophageal diverticula. Management of ZD has different options; however, there is a recent increase in treatment with flexible endoscopic myotomy (FEM). In our study, we aimed to investigate the efficacy and safety of FEM among patients with ZD. MATERIALS AND METHODS: The data of patients who underwent FEM for ZD in our clinic between January 2008 and May 2016 were retrospectively analyzed. Myotomy was performed with a needle-knife sphincterotome by using pulse-cut or forced coagulation electrocautery mode. Myotomy was performed on the common wall of the diverticulum up to 0.5 to 1 cm of the distal end. A handmade diverticuloscope, which was modified from an overtube, was used in most of the patients to focus more carefully on the septum. Dysphagia scores of the patients before and after the procedure were compared and complications were evaluated. RESULTS: A total of 17 patients were enrolled in the study. The mean age was 65.3 years, and mean diverticular diameter was 3.2 cm. The most common symptoms were dysphagia and regurgitation. The mean in-hospital stay was 5 days. The dysphagia score was significantly decreased after FEM among the patients (0.17±0.39 vs. 2±0.79; P=0.0001). Complications were observed in 3 patients (17.6%); however, there was no procedure-related mortality. DISCUSSION: FEM is an efficient and safe procedure as a treatment modality for ZD. However, lack of a standard algorithm is a remarkable disadvantage.

Management of suspected common bile duct stone: diagnostic yield of current guidelines.

BACKGROUND: The American Society for Gastrointestinal Endoscopy (ASGE) has recently published a guideline for suspected CBDS with the intention of reducing unnecessary ERCP and thereby complications. The aim of this study was to assess the diagnostic efficacy of the ASGE guideline. METHODS: Data of patients who underwent ERCP with suspected CBDS were analyzed retrospectively. Patients were classified into high, intermediate and low risk groups based on predictors that have been suggested by the ASGE. Very strong predictors of the presence of ductal stones included: CBDS on transabdominal ultrasonography (US), clinical ascending cholangitis or total bilirubin (TBIL) >4 mg/dL). Strong predictors included dilated CBD >6 mm on US with gallbladder in situ and TBIL level of 1.8-4.0 mg/dL whereas moderate predictor included abnormal liver biochemical test other than bilirubin, age more than 55 years and clinical findings of biliary pancreatitis. RESULTS: Of 888 enrolled patients, 704 had CBDS demonstrated by ERCP and the remainder did not. All very strong and strong predictors were found to be significantly higher among patients who had CBDS. Detection of CBDS by ultrasonography and a dilated common biliary duct were observed to be independent risk factors associated with the existence of CBDS. The high risk group had a high (86.7%) positive predictive value (PPV), however, sensitivity and specificity were observed to be moderate (67.8% and 60.3% respectively). PPV was 67.9% in the intermediate risk group and the sensitivity and specificity were very low (31.9% and 42.3%). DISCUSSION: The probability of CBDS was observed to be high in the intermediate and high risk groups. However due to low sensitivity and specificity values, the ASGE guideline needs additional or different predictors.

Large Balloon Dilation Treatment for Retrieval of Embedded Sharp-pointed Objects in the Esophagus: A New Technique.

Most ingested foreign bodies are best treated with endoscopically. If the sharp-pointed objects embedded in the esophageal wall, it may not be able to be removed by conventional endoscopic devices and surgery is required. Herein, we described a new technique for the extraction of both ends embedded sharp-pointed objects in the esophageal wall.

Cirrhosis with ascites: Is the presence of hemorrhagic ascites an indicator of poor prognosis?

BACKGROUND/AIMS: Hemorrhagic ascites in patients with cirrhosis is described as a RBC (Red Blood cell) > 50,000/mm³ and leads to increased morbidity and mortality. Positive red blood cells at a level of less than 50,000/mm³ (10,000-50,000) may be encountered in the ascites but it is not known whether this is clinically significant or not. This study aimed to examine the outcome of hemorrhagic ascites in patients with advanced cirrhosis. MATERIALS AND METHODS: Data from 329 cirrhotic patients with ascites who received paracentesis at least once due to ascites was retrospectively analyzed from the period of 2007-2013 from the Türkiye Yüksek Ihtisas Hospital, Department of Gastroenterology. Patients were divided according to the number of RBC, with greater than 10,000/mm³ being described as hemorrhagic ascites, and less than 10,000/mm³ described as the normal or control group. Patient data included: number of accepted intensive unit service stays, acute kidney injury (AKI), hepatic encephalopathy (HES), model for end-liver disease (MELD) score, Child Pugh score (CPS), degree of esophageal varices, spleen size and mortality rates. RESULTS: Patients were defined as having hemorrhagic ascites with a RBC count greater than 10,000/mm³ in 118 (35.9%) patients and as a non-hemorrhagic ascites group with less than 10,000/mm³ in 211 (64.1%) patients. The hemorrhagic ascites group had advanced liver disease symptoms compared to the control group. Meld score in the hemorrhagic group was statistically higher than in the control group (21.5±8.3 vs. 17.3±6.6; p value: 0.001). The median value of bilirubin was 5.9 (0.45-33) in the hemorrhagic ascites group and 4.01 (0.39-33) in the non-hemorrhagic group (p value: 0.001). Using multivariate logistic regression analysis, hemorrhagic ascites was also an independent predictor of mortality (HR 2.7 1.4-6.3), with other mortality indicators being HCC (HR 3.1 1.5-6.4) and HRS (HR 2.6 1.2-5.5). CONCLUSION: Patients with hemorrhagic ascites had higher HRS, SBP and admissions to the intensive care unit. We believe that the presence of hemorrhagic ascites can be used as a marker for advanced liver disease and for predicting mortality.

Can a Fully Covered Self-Expandable Metallic Stent be Used Temporarily for the Management of Duodenal Retroperitoneal Perforation During ERCP as a Part of Conservative Therapy?

PURPOSE: There are no reports comparing the results of conservative/nonsurgical management with the addition of fully covered self-expandable metallic stents (FCSEMS) with the conservative approach in endoscopic retrograde cholangiopancreatography (ERCP)-related duodenal retroperitoneal (type II) perforations. The aim of this study was to evaluate whether the addition of FCSEMS to conventional treatment provides further benefits in the course of type II perforations. METHODS: A total of 7471 ERCP with sphincterotomy performed between 2007 and 2014 were evaluated, and a total of 25 type II perforations (0.33%) were identified. About 20 patients who were detected during ERCP and biliary cannulation was accomplished were included in the study. Patients were divided into 2 groups: the conservative treatment group (10 patients) and the FCSEMS group (10 patients). Groups were compared for clinical findings, results of serial white blood cell (WBC) counts, the length of hospital stay, the need for surgery, and death, retrospectively. RESULTS: Five patients in the conservative treatment group and none of the patients in the FCSEMS group had pain requiring narcotic and/or nonsteroidal anti-inflammatory analgesics during the follow-up period (P=0.005). On post-ERCP day 1, in the conservative and the FCSEMS groups, mean WBC counts were 13,218±4410×10 and 8714±3270×10, respectively (P=0.029). The perforation-related length of hospital stay was 15.77±5.21 days in the conservative group and 11.7±3.19 days in the FCSEMS group (P=0.053). Excluding the patient with severe pancreatitis in the conservative group, there were no deaths or need for surgery. CONCLUSIONS: Compared with conservative treatment alone, the addition of FCSEMS provides further benefits in terms of a painless course, lower WBC counts, and a short hospital stay. FCSEMS can be used as an additional treatment modality in type II perforation.

Prevalence of gestational diabetes mellitus and associated risk factors in Turkish women: the Trabzon GDM Study.

INTRODUCTION: The aim of this study was to investigate the prevalence of gestational diabetes mellitus (GDM) in Turkish pregnant women in the Trabzon Region and further to identify population-specific risk factors for GDM. MATERIAL AND METHODS: In this prospective cross-sectional survey, universal screening for GDM was performed in 815 pregnant women. Screening was done with a 50-g oral glucose challenge test (GCT) with a 140 mg/dl cut-off point, then a diagnostic 100 g oral glucose tolerance test (OGTT) was performed according to Carpenter and Coustan (CC) criteria. RESULTS: The GCT was positive in 182 (22.3%) cases. The OGTT was performed on the 182 screen-positive pregnant women. Thirty-five were diagnosed with GDM on the basis of their results for a prevalence of 4.3% (35/815). Of the pregnancies with negative GCT but having high risk factors for GDM (n = 31), 4 were diagnosed with GDM (0.5%). Prevalence of GDM was found to be 4.8% (n = 39) for all pregnant women. Gestational diabetes mellitus was positively associated with advanced maternal age (p < 0.001), prepregnancy body mass index (p < 0.001), cessation of cigarette smoking (p < 0.001), excessive weight gain during pregnancy (p = 0.003), previous history of GDM (p < 0.001), history of selected medical conditions (p = 0.018), family history of diabetes (FHD) (p < 0.001), and existence of at least one high risk factor for GDM (p < 0.001). In multiple logistic regression analysis, independent predictors for GDM were maternal age, cessation of cigarette smoking, increasing prepregnancy body mass index, weight gain of more than 8 kg during pregnancy, GDM history in previous pregnancies and a history of diabetes in first-degree relatives of pregnant women. CONCLUSIONS: The prevalence of GDM in Trabzon province was found as moderate. Commonly recognized risk factors including older age, prepregnancy obesity, FHD and past history of GDM, are valid for our urban Turkish population. Also, excessive weight gain in pregnancy and cigarette cessation were observed to be nontradional risk factors of GDM. It was concluded that all pregnant women should be screened for GDM if prevalence was not low.

Diverticulum With Papillae: Does Position of Papilla Affect Technical Success?

BASIS AND PURPOSE: The presence of peripapillary diverticulum (PPD) can cause some biliary diseases, especially common bile duct stones, and also, literally, can change the technique of endoscopic retrograde cholangiopancreatography (ERCP) and affect the complication ratio of this procedure. In this study, we investigate the effect of localization and position of the papilla according to the diverticulum on the success of therapeutic ERCP procedures. MATERIALS AND METHODS: The study was conducted prospectively in the patients with naive papillae, who underwent ERCP for a period of 16 months. In all patients, the position of papillae according to the diverticulum (the periphery of the diverticulum is thought as the clock circumference, and the position of papillae is defined as the dials of clock), the success rate of biliary cannulation, total procedure time, overall treatment success rate of ERCP, and the complications are investigated. RESULTS: During this period, 222 (18.5%) of the 1205 enrolled patients who underwent ERCP had PPD. Of the patients with PPD, 123 (55.4%) were female and 99 (44.6%) were male, and the median age was 68.9±10.1 years. According to the position of the papilla by the diverticulum, 90 (40.5%) patients have it on 7 o'clock position, 64 (28.8%) patients have on 6 o'clock position, 63 (28.3%) patients have on 5 o'clock position, and 5 (2.3%) patients have on 1 o'clock position. In the cases of the papilla on 1 o'clock position according to the diverticulum, cannulation procedures were found to be more difficult than other patients (P<0.05). The presence of the diverticulum did not affect the success of therapeutic procedures and did not increase the ratio of complications. CONCLUSIONS: In the presence of PPD, additional cannulation techniques may be required for the procedure. Particularly, the aid of percutaneous techniques may be needed for the papilla on 1 o'clock position.
