Acute pancreatitis in Turkey: Results of a nationwide multicenter study

BACKGROUND

Acute pancreatitis (AP) is the most common gastrointestinal disease requiring hospitalization, with significant mortality and morbidity. We aimed to evaluate the clinical characteristics of AP and physicians' compliance with international guidelines during its management.

METHODS

All patients with AP who were hospitalized at 17 tertiary centers in Turkey between April and October 2022 were evaluated in a prospective cohort study. Patients with insufficient data, COVID-19 and those aged below 18 years were excluded. The definitions were based on the 2012 revised Atlanta criteria.

RESULTS

The study included 2144 patients (median age:58, 52 % female). The most common etiologies were biliary (n = 1438, 67.1 %), idiopathic (n = 259, 12 %), hypertriglyceridemia (n = 128, 6 %) and alcohol (n = 90, 4.2 %). Disease severity was mild in 1567 (73.1 %), moderate in 521 (24.3 %), and severe in 58 (2.6 %) patients. Morphology was necrotizing in 4.7 % of the patients. The overall mortality rate was 1.6 %. PASS and BISAP had the highest accuracy in predicting severe pancreatitis on admission (AUC:0.85 and 0.81, respectively). CT was performed in 61 % of the patients, with the majority (90 %) being within 72 h after admission. Prophylactic NSAIDs were not administered in 44 % of the patients with post-ERCP pancreatitis (n = 86). Antibiotics were administered to 53.7 % of the patients, and 38 % of those received them prophylactically.

CONCLUSIONS

This prospective study provides an extensive report on clinical characteristics, management and outcomes of AP in real-world practice. Mortality remains high in severe cases and physicians' adherence to guidelines during management of the disease needs improvement in some aspects.

Risk of Bleeding After Percutaneous Endoscopic Gastrostomy in Patients Using Antithrombotic Drugs

BACKGROUND

The rate of using antithrombotic (AT) drugs is frequently high in patients who require percutaneous endoscopic gastrostomy (PEG). The aim of this study was to determine whether the risk of bleeding after PEG increases in patients whose AT drugs were discontinued according to the European Society Gastrointestinal Endoscopy guidelines (warfarin for 5 d, low molecular weight heparin for 24 h, DOAC for 3 d, and clopidogrel for 7 d).

PATIENTS AND METHODS

Data from 243 patients, who underwent PEG tube placement and received AT drugs and 206 patients who did not between 2018 and 2021 in our hospital, were evaluated retrospectively. Bleeding was defined as requiring blood transfusion, hematemesis and/or melena, decreased hemoglobin, or bleeding from PEG.

RESULTS

A total of 243 (54.1%) patients (121 (49.7%), women, mean age (75.7 y) who underwent PEG and received AT drugs, and 206 (45.9%) patients who did not (92 (44.6%), women, mean age (63.15 y). The medications and bleeding rates of the patients are given in Table 1. The rate of bleeding in patients using AT medication was significantly higher than that in patients not using medication (Table 2) ( P = 0.007). When the AT drugs were compared among themselves, the bleeding risk did not differ. Bleeding was detected in 10 patients with bleeding from the PEG tube in 4 with melena. Bleeding detected in 14 patients was controlled with adrenaline injections. None of the patients required transfusion or repeat endoscopies. No bleeding-related deaths were reported.

CONCLUSION

Even if patients receiving AT drugs are treated as recommended by international guidelines, it should be kept in mind that bleeding may occur after PEG, and the patients should be followed accordingly.

Validation of the Revised Atlanta Criteria in determining the severity of acute pancreatitis

BACKGROUND/AIM

Determining the severity of acute pancreatitis (AP) is crucial for patient management. The aim of our study was to assess the accuracy and limitations of the Revised Atlanta Criteria (RAC) in determining the severity of AP.

MATERIALS AND METHODS

The study was retrospectively conducted on AP patients admitted to the Gastroenterology Department of Sakarya University Faculty of Medicine. The severity, morphology and local complications of AP were evaluated according to the RAC. Laboratory parameters, clinical scores predicting disease severity and Computer Tomography Severity Index scores were assessed.

RESULTS

The study group included 113 patients. Ninety-eight (86.7%) had interstitial edematous, and 15 (13.3%) had necrotizing pancreatitis. AP pancreatitis was mild in 69 (61.1%), moderate in 33 (29.2%), and severe in 11 (9.7%). Compared to the moderate group, patients in the severe group had a higher hematocrit, creatinine, SIRS and BISAP scores at admission and more length of hospital stay, more ICU requirements, and higher mortality rates ( P  < 0.05). Eleven patients had single or multiple persistent organ failure (POF). The mortality rate of patients who developed early POF (n = 6) was higher compared to the group of patients who developed late POF (n = 2) (83.3% and 40%, respectively).

CONCLUSION

Severity assessment using the RAC in patients with AP is consistent with laboratory parameters and scoring systems predicting severity. Severe pancreatitis cases who develop early POF may be classified separately.

Diagnosis and surgical treatment of cysto-gastric fistula out of an hepatic hydatid cyst. Unusual case

BACKGROUND

Hydatid cyst is an endemic zoonotic infection that annual incidence ranges from <1 to 200 per 100,000 individuals. The most common complication of hepatic hydatid cyst reported is rupture of the cysts, most commonly intrabiliary rupture. Direct rupture to hollow visceral organs is rarely seen. We describe here an unusual cystogastric fistula in a patient with liver hydatid cyst.

CASE PRESENTATION

The 55-year-old male patient presented with right upper quadrant abdominal pain. After radiological imaging studies, the diagnose was of hydatid cyst involving the left lateral segment of the liver ruptured into the gastric lumen and resulted in a cystogastric fistula. Gastroscopy revealed that the cyst and its contents protruding from anterior wall to the gastric lumen. Partial pericystectomy and omentopexy were performed and the gastric wall was primarily repaired. There were no complications in the postoperative period and 3-month follow up.

CONCLUSION

This case, to our knowledge, is the first reported case of cystogastric fistula surgically treated in a patient with liver hydatid cyst in the literature. Our clinical experience shows that, although it is a benign disease, complicated hydatid cysts should be evaluated in detail preoperatively, and after the detailed diagnostic work-up, surgical therapy might be planned individually for each case.

KEY WORDS

Cysto-gastric fistula, Hydatid Cyst, Liver hydatidosis.

Fully Covered Metal Stents Safely Facilitate Extraction of Difficult Bile Duct Stones

BACKGROUND

Ten to 15% of the common bile duct (CBD) stones require advanced endoscopic extraction techniques during endoscopic retrograde cholangiopancreatography. The study aimed to evaluate the efficacy and safety of fully covered self-expandable metal stents (FC-SEMS) for facilitating the extraction of difficult bile duct stones.

METHODS

Patients who received FC-SEMS for the extraction of difficult CBD stones were retrospectively reviewed. Group 1 included patients with extrahepatic stones above a distal CBD stricture, Group 2 included patients with intrahepatic stones above a hilar stricture, and Group 3 included patients with complex stone(s) and no biliary stricture. Complete stone clearance rate and complications of FC-SEMS treatment were evaluated.

RESULTS

The study group included 33 procedures on 32 patients (mean age: 55±17, 56.3% male). FC-SEMS was placed as a primary treatment in 15 (45.5%) procedures. Complete stone clearance was achieved in 84.6% of the procedures in Group 1, 100% in Group 2, and 87.5% in Group 3 ( P =0.23). Overall, complete stone clearance was achieved in 30 of the 33 procedures (90.9%). None of the patients developed pancreatitis, cholecystitis, or cholangitis. Stent migration occurred in 4 procedures (12.1%), and all were clinically insignificant.

CONCLUSION

FC-SEMS is effective and safe for facilitating treatment of difficult bile duct stones.

The DETAIL questionnaire is a useful and effective tool to assess spondyloarthritis in patients with inflammatory bowel disease

Introduction

This study aimed to determine the effectiveness of adding a simple questionnaire related to musculoskeletal system to routine outpatient examination to detect undiagnosed axial and peripheral arthropathy in patients with inflammatory bowel disease (IBD).

Materials and methods

A musculoskeletal symptom questionnaire was given to all patients with IBD during their follow-up examinations between January 2020 and November 2021. The DETAIL questionnaire consisting of six questions about the musculoskeletal system was administered by asking the patients with IBD. All patients who answered yes to at least one of these questions were directed to specialists in the rheumatology department to undergo a detailed examination. The patients who were diagnosed with rheumatological disease after further investigation were recorded. Patients with a known diagnosis of rheumatological disease were excluded from the study.

Findings

There were 333 patients with IBD included in the study. Of these patients, 41 (12.3%) had a previously diagnosed rheumatological disease and were excluded from the evaluation. Of the remaining 292 patients (147 with ulcerative colitis, 139 with Crohn's disease and six with indeterminate colitis; mean age 42 years), 67 (23%) answered yes to at least one of the questions and were referred to a rheumatology consultation. Rheumatological examination was completed in 52 patients. As a result of the evaluations, 24 patients (8.2%) were diagnosed with enteropathic arthritis (14 axial, 9 peripheral, and 1 axial plus peripheral). Patients with newly diagnosed enteropathy had a lower median disease age than patients without enteropathy.

Conclusion

The DETAIL questionnaire is an effective and easy tool for identifying missed cases of SpA in patients with IBD.

The impact of COVID-19 disease on the natural course of cirrhosis: Before and after starting vaccination

Background

Cirrhosis has been reported as an important risk factor for death in coronavirus disease 2019 (COVID-19) disease. In this study, we aimed to investigate the effects of COVID-19 on the natural course of cirrhosis before and after starting vaccination.

Methods

The cirrhosis patients in our cohort (n: 140; median age:56; 71 female) were included in this study. The median MELD (Model For End-stage Liver Disease) score was 11 (6-25) and CCI (Charlson Comorbidity Index) score was 4 (1-11). In total, 85 had CTP (Child-Turcotte-Pugh)-A, 44 had CTP-B and 11 had CTP-C cirrhosis. The course of COVID-19 in this patient group was evaluated before and after COVID-19 vaccination.

Results

Between March 2020 and January 2021, 36 of the 140 cirrhosis patients had developed COVID-19. Cirrhosis (+)/COVID-19 (+) and Cirrhosis (+)/COVID-19 (-) groups did not differ in terms of age, CCI and MELD-Na scores, or gender. There were six deaths in the Cirrhosis (+)/COVID-19 (+) group and five in the Cirrhosis (+)/COVID-19 (-) group [6/36 (16.6%) vs. 5/104 (4.8%); p: 0.03]. Patients who died were older, had higher CCI and MELD-Na scores, and lower albumin levels. Having had COVID-19 [6.45 (1.43-29.4); p: 0.015], higher MELD-Na score [1.35 (1.18-1.60); p: 0.001] and higher CCI score [1.65 (1.14-2.39); p: 0.008] were found to be independent predictors of mortality. After effective vaccination started in Turkey, only 11 of the remaining 129 patients developed COVID-19, and only one patient died, who was unvaccinated.

Discussion

In our cirrhotic cohort, COVID-19 disease was associated with 16% mortality in the pre-vaccination period. COVID-19 vaccination prevents serious illness and death due to COVID-19 in cirrhotic patients.

Endoscopic treatment of periampullary duodenal duplication cyts in an 18-month-old girl

BACKGROUND

Duodenal duplication cysts (DDC) are rare congenital anomalies of the gastrointestinal tract and periampullary localization with anatomical variants including biliary and pancreatic duct anomalies remains a surgical challenge. Endoscopic treatment of the periampullary DDC (PDDC) communicating with the pancreaticobiliary duct in an 18-month-old girl is presented to discuss the endoscopic treatment options in children.

CASE

An 18-month-old girl with a normal prenatal ultrasound (US) was asymptomatic until complaining of abdominal pain and vomiting at 10-months of age. Abdominal US revealed a 1.8 × 2 cm cystic mass adjacent to the second part of the duodenum. The amylase and lipase levels were slightly increased while she was symptomatic. Magnetic resonance cholangiopancreaticography (MRCP) showed a thick cyst wall measuring 1.5 × 2 cm at the second part of the duodenum, consistent with DDC that was suspected to be communicating with the common bile duct. Upper gastrointestinal endoscopy confirmed a bulging cyst in the duodenum lumen. The puncture and injection of the cyst with contrast material confirmed the communication of the duplication cyst with the common bile duct. The unroofing of the cyst was performed with endoscopic cautery. The biopsy obtained from the cystic mucosa revealed normal intestinal histology. Oral feeding was initiated six hours after the endoscopy. The patient has been followed for the last 8 months uneventfully.

CONCLUSIONS

Endoscopic treatment of PDDC with various anatomical variants can be considered an alternative to surgical excision in children.

The Classification of Biliary Strictures in Patients With Right-Lobe Liver Transplant Recipients and Its Relation to Traversing the Stricture With a Guidewire

BACKGROUND

Traversing the stricture with a guidewire is a prerequisite for the endoscopic treatment of biliary strictures after living donor liver transplantation. We aimed to evaluate the effect of variations in the biliary anastomosis and strictures on the success of endoscopic treatment and suggest a cholangiographic classification.

METHODS

The 125 strictures among the 104 patients with right-lobe living donor liver transplantation were reviewed. The strictures were classified by the anastomosis pattern according to the number (1, 2, or >2), location (common bile, hepatic, or cystic duct), the angle between the proximal and distal sites of the anastomosis, and the contrast enhancement pattern. The relationship between the success rate of traversing the anastomosis and the classification was evaluated.

RESULTS

Of the 125 biliary strictures, 86 (68.8%) could be passed via endoscopically. Thirty-three strictures were managed either percutaneously (n = 13) or by magnetic compression anastomosis (n = 20). Compared with the round, the triangular (odds ratio [OR], 6.5), the intermediate form (OR, 17.7), and the end-to-side anastomosis (OR, 5.1) were associated with an increased chance of traversing. The contrast enhancement pattern of the strictures and the bile ducts was also related to the successful rate of the endoscopic treatment (P < 0.001). The success rate was higher in the patients with the angle between the proximal and distal sites of the anastomosis approximated was small (0°-30° = 74%, 30°-60° = 69%, 60°-90° = 63%, >90° = 41%).

CONCLUSIONS

The type of biliary anastomoses and stricture affect the success rate of endoscopic treatment. These data may play role in making decision about the type of anastomosis during the surgery.

Impact of COVID-19 Pandemic on Gastroenterology Fellowship Training in Turkey: A Prospective Nationwide Survey Study

BACKGROUND

The Coronavirus-2019 disease (COVID-19) pandemic has markedly restricted endoscopic and clinical activities in gastroenterology (GI), with a negative impact on trainee education. We aimed to inve stigate how and to what extent has GI trainees in Turkey are affected by the current pandemic in terms of general, psychological, and educational status.

METHODS

We conducted a web-based survey sent electronically to 103 official GI trainees in Turkey from 37 centers. The 32-item survey included questions to capture demographic (5-questions), endoscopic (7-questions), personal protective equipment (PPE) (3-questions), psychological and general well-being (11-questions), and educational (6-questions) data.

RESULTS

Ninety-six (93.2%) trainees completed the survey, of which 56.3% (n = 54) reported a decrease in independently performed endoscopic procedures. Due to pandemic, 91.7% of standard diagnostic endoscopic procedures, 57.2% of standard therapeutic procedures, and 67.7% of advanced endoscopic procedures were decreased. Out of 96 respondents, we detected signs of anxiety in 88.5%, exposure concern in 92.7%, concerns for prolongation of training period in 49%, loss of concentration and interest in 47.9%, and burnout syndrome in 63.5%. Female gender (odds-ratio: 3.856, 95% confidence interval: 1.221-12.174, P = .021) was the only independently associated factor with pandemic-related anxiety.

CONCLUSIONS

COVID-19 pandemic has led to high amounts of anxiety and non-negligible rates of burnout syndrome among GI trainees, with a significant reduction in endoscopic activities. More effort and novel strategies are required to deliver sufficient competence and general-psychological well-being to GI trainees.

Comparison of Tenofovir Disoproxil Fumarate and Entecavir in the Prophylaxis of HBV Reactivation

INTRODUCTION

Current guidelines recommend starting antiviral prophylaxis to prevent hepatitis B virus (HBV) reactivation in patients receiving immunosuppressive treatments (IST). The aim of this study was to compare the efficacy of entecavir (ETV) and tenofovir disoproxil fumarate (TDF) for prophylaxis.

METHODS

Patients, who were HBsAg and/or anti-HBc IgG positive and scheduled to receive IST for oncologic and hematologic diseases, were enrolled into the study. Those who were already receiving an antiviral treatment for HBV or had an associated HIV, hepatitis C, D were excluded. The remaining patients with a prophylaxis indication according to the AGA guideline were randomized to receive either ETV (0.5 mg/day) or TDF (245 mg/day). Prophylaxis was continued for 6-12 months after completion of IST. Patients were followed up for 1 year after completion of prophylaxis. The HBV reactivation rates and side effects of the drugs were compared.

RESULTS

The study group included 120 patients. There was no significant difference between the demographic data, viral serologic parameters and reactivation risk profiles of the ETV (n = 60) and TDF (n = 60) groups. Forty-one patients in the ETV and 36 in the TDF group completed the antiviral prophylaxis, and no HBV reactivation was observed. HBV reactivation was observed in 4 of 37 patients (10.8%) in the ETV group and 5 of 35 (14.3%) patients in the TDF group (including one with flare) during the follow-up after completion of prophylaxis. Ten patients in the ETV group (16.7%) and 14 patients (23.3%) in the TDF group experienced side effects (p = 0.77). One patient in the TDF group had to switch to ETV due to severe itchy, maculopapular rash-like lesions.

CONCLUSIONS

ETV and TDF had a similar efficacy in the prophylaxis of HBV reactivation in patients undergoing IST, with none of the patients experiencing reactivation.

Incidence, Risk Factors, and Treatment of Proximally Migrated Pancreatic Stents

AIM

The aim of this study was to investigate the incidence, risk factors, and treatment strategies of proximally migrated pancreatic stents.

MATERIALS AND METHODS

The data of 626 sessions of 421 patients with pancreatic duct stenting were retrospectively analyzed between 2010 and 2018, and patients with proximally migrated stents were included in the study.

RESULTS

Of 626 stents examined, 77 migrated proximally (12%). The migration rate (MR) was 16%, 2%, and 7%, respectively, in patients treated with chronic pancreatitis, malignancy, and pancreatic leakage indication. The MR was 14% in procedures with pancreatic duct stenosis, 21% in procedures with pancreatic sphincterotomy, and 27% in procedures performed from minor papillae. The MR of the 5, 7, and 10 Fr stents was 4%, 17%, and 10%, respectively. Of the 77 migrated stents, 64 were successfully removed (83%). This success rate (SR) was 84% in procedures with chronic pancreatitis indication, 83% in procedures with pancreatic duct stenosis, 79% in procedures with sphincterotomy, and 75% in procedures performed from minor papillae. The SR of the 5, 7, and 10 Fr stents was 100%, 79%, and 92%, respectively. It was also determined that 33 stents were fractured and migrated (43%). The SR of the fractured stents was 76%. Moreover, of the stents that were successfully removed, 35 were removed with forceps (55%) and 15 (23%) were removed with a balloon. Furthermore, in 47 cases, the stent was removed in the first session (73%). Acute pancreatitis occurred in 5 patients (8%) and perforation occurred in 1 patient (2%).

CONCLUSION

In this study, it was shown that proximal migration of pancreatic stents is frequent and most of these stents can be removed successfully.

POS0968 ARE THERE CLUES FOR THE SCREENING OF SPONDYLOARTHRITIS IN PATIENTS WITH INFLAMMATORY BOWEL DISEASES?

Background:

SpA is the most frequent extra-intestinal manifestation in patients with IBD (1). Questioning IBD patients in terms of SpA and referring patients to the rheumatology clinic is important for early diagnosis and treatment management.

Objectives:

We aimed to diagnose SpA early by using the DETAIL questionnaire to IBD patients and to compare it with the study validated for each question (2).

Methods:

In the Hacettepe University Gastroenterology Clinic, patients with IBD were questioned for musculoskeletal symptoms between March 2019 and September 2020. For this purpose, a validated DETAIL questionnaire consisting of 6 questions was asked. Patients with at least 1 positive out of 6 questions were consulted in the rheumatology clinic, and patients were evaluated for SpA by physical examination, laboratory, and imaging. For each question in the detection of arthritis in inflammatory bowel diseases (DETAIL) questionnaire, sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio (LR) were calculated.

Results:

217 IBD patients were included in the study. Twenty patients with previously known rheumatologic diseases were excluded from the study. 49 (24%) of the remaining 197 patients had a positive answer to at least one question in the DETAIL query. 39 (20%) of these patients were evaluated in the rheumatology clinic, and 16 (8.1%) of them were diagnosed with SpA (spondylitis: 9, peripheral arthritis: 7) (Figure 1). In the DETAIL questionnaire, two patients answered 5/6 yes, five patients answered 4/6 yes, eleven patients answered 3/6 yes, ten patients answered 2/6 yes, and eleven patients answered 1/6 yes. In the six items of DETAIL, the best performances in discriminating patients affected by SpA were found in the second and fourth questions (LR + 2.9 and 1.57, respectively) (Table 1).

Conclusion:

41% of IBD patients who answered yes to at least one question in the DETAIL questionnaire were diagnosed with SpA. Especially those with sausage fingers or low back pain for at least 3 months seem more likely probability to be diagnosed with SpA. Unlike the validated study, the probability of having diagnosis of SpA was not observed in questions five and six, which questioning the inflammatory back pain parameters. The DETAIL questionnaire may be used as a useful screening tool for the detection of SpA.

AB0491 THE IMPORTANCE OF MUSCULOSKELETAL SYMPTOM QUESTIONING IN INFLAMMATORY BOWEL DISEASES

Background:

Spondyloarthritis (SpA) occurs in up to 13% of patients with inflammatory bowel disease (IBD) (1). Early diagnosis and treatment of SpA in IBD patients prevents irreversible musculoskeletal diseases.

Objectives:

The aim of this study is to emphasize the importance of questioning musculoskeletal symptoms in patients with IBD.

Methods:

In the Hacettepe University Gastroenterology Clinic, patients with IBD were questioned for musculoskeletal symptoms between March 2019 and September 2020. For this purpose, a validated DETAIL questionnaire (2) consisting of six questions was asked (1. Have you ever had a finger or a toe and/or another joint swollen and painful for no apparent reason? 2. Occasionally, has an entire finger or toe becomes swollen, making it look like a ‘sausage’? 3. Have you had pain in your heels? 4. Have you ever had back pain lasting at least 3 months that was not injury related? 5. Do you have low back pain in the morning and/or after resting that improves with exercise? 6. Do you wake up at night because of low back pain?). Patients with at least 1 positive out of 6 questions were consulted in the rheumatology clinic, and patients were evaluated for SpA by physical examination, laboratory, and imaging. Demographic and clinical characteristics of IBD patients with and without SpA were compared.

Results:

217 IBD patients were included in the study. Twenty patients with previously known rheumatologic diseases were excluded from the study. 49 (24%) of the remaining 197 patients had a positive answer to at least one question in the DETAIL query. 39 (20%) of these patients were evaluated in the rheumatology clinic, and 16 (8.1%) of them were diagnosed with SpA (spondylitis: 9, peripheral arthritis: 7) (Figure 1). There were no significant differences in terms of age, gender, IBD type, duration of IBD, current treatment, fibromyalgia syndrome (FMS) and depression according to Beck depression inventory between patients with IBD with and without SpA (Table 1).

A Simple Method for Endoscopic Treatment of Large Gastric Phytobezoars: "Hand-Made Bezoaratome"

BACKGROUND

Large gastric phytobezoars are generally resistant to standard chemical or endoscopic treatments. We presented our experience of an alternative endoscopic method using a hand-made tool called a "hand-made bezoaratome" for the treatment of large gastric phytobezoars.

METHODS

Patients who consulted or who were diagnosed with gastric bezoars at an education and research hospital between January 2015 and December 2018 were prospectively included in the study. Patients with phytobezoars of 50 mm and larger were included in the study. Patients with trichobezoars, lactobezoars, pharmacobezoars, under 18 years of age, and pregnant women were excluded. A 0.25 mm diameter guidewire and a mechanical lithotripter sheath were used to prepare the "hand-made bezoaratome." After the first procedure, patients were advised to consume 2500 mL of Coca Cola® or the same amount of pineapple juice per day, until the next procedure. Endoscopic procedures were performed at 5-day intervals until complete reabsorption of the bezoar was achieved. Patients were followed up for 6 weeks.

RESULTS

The study group included 37 (21 males, mean age: 57.6 ± 12.5 years) patients. The median size of the phytobezoars was 71 mm (50-90). The median endoscopic procedure time was 853 s (380-1940 s). The success rate for endoscopic fragmentation was found to be 100%. No major complications occurred during the endoscopic procedures, but 1 patient (2.7%) required surgery for ileus due to an obstruction at the distal part of the jejunum, 61 h after the second endoscopic session. The overall success rate of the endoscopic treatment was 97.3%.

CONCLUSION

Using a "hand-made bezoaratome" is effective and reliable for the endoscopic treatment of large gastric bezoars.

A case report of tigecycline induced acute pancreatitis in a renal transplant patient and review of the literature: Should we avoid tigecycline in patients on calcineurin inhibitors?

Tigecycline has been approved by the US (United States) Food and Drug Administration in a variety of complicated infections due to its broad-spectrum antibiotic activity. Following phase III trials, the product label was revised and acute pancreatitis was listed as an adverse effect. Its safety profile in special groups such as renal transplant patients is not exactly known. We report the first case of unintentional rechallenge of tigecycline induced pancreatitis in a renal transplant patient. Ten days following the renal transplantation, a 35-year-old patient presented to the clinic with acute rejection. He received anti-thymocyte globulin (ATG) and pulse steroid treatments for rejection. Following the treatment, he developed perianal cellulitis and tigecycline was started. Nine days following initiation of tigecycline he received thrombectomy for his incidental cardiac thrombus. One day after thrombectomy, he developed acute pancreatitis (AP). Thrombectomy was suspected to be the cause of AP. During hospitalization for transplant rejection, tigecycline was re-started for a newly developed complicated abdominal infection. On the third day of the tigecycline re-treatment, he developed a second episode of AP. Following tigecycline withdrawal, his symptoms resolved and serum pancreatic enzymes returned to normal, thus AP was ultimately attributed to tigecycline. This lethal side effect should be kept in mind while treating severe infections in renal transplant recipients.

The Importance of Eosinopenia for Predicting Treatment Response in Patients with Cholangitis

OBJECTIVE

To compare recovery of eosinopenia, C-reactive protein (CRP) and procalcitonin levels in predicting the response to treatment in patients with cholangitis.

STUDY DESIGN

Descriptive, analytical study.

PLACE AND DURATION OF STUDY

Department of Gastroenterology, Sakarya Training and Research Hospital, Turkey between September 2018 and February 2019.

METHODOLOGY

 Patients with cholangitis, who underwent endoscopic retrograde cholangiopancreatography (ERCP), were inducted. Those with choledocholic thiasis alone were considered controls. Eosinophil count above 100.5 cells/µL was the limit value accepted as improvement. ERCP repeat was decided according to eosinophil count below 100.5 and not clinically improving. Relationship between inflammatory markers such as CRP, procalcitonin and eosinopenia values in patients with stone-associated cholangitis was investigated.

RESULTS

The cholangitis group was comprised of 62 patients [mean age 67±14.57 years; 26 (41.9%) female], while control group was comprised  of 57 patients [mean age 57.4±18.10 years; 39 (68.4%) females, p=0.004]. At time of admission, median eosinophils was significantly lower in cholangitis group at 17.50 [9.82-84] ×103/µL compared to control group at 168 [100.11-270] ×103/µL (p=0.001). ERCP were repeated on two patients as their clinical conditions and unremitting eosinophil counts worsened. Eosinophil and CRP markers and clinical improvement were observed after  second ERCP procedure.

CONCLUSION

Eosinopenia may be used as inflammatory marker in  evaluation of response to treatment and for predicting the need to repeat ERCP during clinical follow-up of patients who undergo cholangitis treatment. Key Words: Cholangitis, C-reactive protein, Endoscopic retrograde cholangiopancreatography, Eosinopenia, Procalcitonin.

Extracorporeal shock wave lithotripsy in the management of a 14-year-old girl with chronic calcific pancreatitis

BACKGROUND

Chronic pancreatitis is very rare in childhood and causes chronic/relapsing abdominal pain, frequent hospitalizations, malnutrition, growth retardation, and stone formation in the main duct. Although pancreatic extracorporeal shock wave lithotripsy (P-ESWL) is commonly used in the treatment of pancreatic stones (PS) in adults, the use in children is still controversial. An adolescent girl with multiple PS is presented to discuss the use of ESWL as a treatment alternative in children with PS.

CASE

A 14-year-old girl was admitted with abdominal pain and elevated pancreatic enzyme levels. Abdominal US showed irregularity and rough echogenicity in pancreas revealing pancreatitis. Multiple stones were seen in main pancreatic duct on Magnetic resonance cholangiopancreatography (MRCP). Endoscopic retrograde cholangiopancreatography (ERCP) was performed and dilated pancreatic duct, thickened pancreatic secretion were detected. Endoscopic sphincterotomy was performed. Endoscopic removal of stones could not be achieved since the largest stone was 17x8 mm. Pancreatic extracorporeal shock wave lithotripsy (P-ESWL) was performed using electromagnetic lithotripter under general anesthesia. Following ESWL, fragmentation of stones in the main duct was confirmed with ERCP. After 3 sessions of ESWL, no ESWL-related complication was observed. Pain relief was achieved. The patient is still under follow-up regarding endocrine and exocrine function of pancreas.

CONCLUSION

ESWL may be an effective and safe management option in pediatric PS which could not be removed by ERCP. The patients managed with ESWL should be followed-up for a long time regarding the endocrine and exocrine functions of the pancreas. As in management of adult pancreatitis, clinical guidelines are needed regarding the management of pediatric PS.

Choledochoscope-assisted antegrade-retrograde endoscopic dilation of complete esophageal stenosis in a patient with dystrophic epidermolysis bullosa

Dystrophic epidermolysis bullosa is a mucocutaneous disorder, characterized by recurrent formation of blisters and scarring. The gastrointestinal tract is commonly affected by the disease and the proximal esophagus is the most common area of involvement of the gastrointestinal tract. The esophageal strictures are common in patients with dystrophic epidermolysis bullosa that can lead to complete esophageal stenosis in some cases. The antegrade/retrograde endoscopic dilation is a commonly used method in these patients. Different kinds of endoscopes may be used for the retrograde procedure, such as conventional upper gastrointestinal (UGI) endoscopes, slim-paediatric UGI endoscopes and ultrathin UGI nasal endoscopes. Herein, we reported the first antegrade/retrograde esophageal dilation case performed under choledochoscopic guidance.

Endoscopic retrograde cholangiography via a permanent access loop

BACKGROUND/AIMS

The aim of this study was to investigate the indications, technical and clinical success, and complications of the endoscopic retrograde cholangiography (ERC) via a permanent access loop (PAL).

MATERIALS AND METHODS

Twenty patients who underwent ERC through PAL between 2009 and 2017 were included in this study. The technical success was described as achieving access to the bile ducts through PAL and the clinical success was described as the clinical and laboratory improvement of the patients after the procedure.

RESULTS

The study was performed with 20 patients. The median follow-up duration was 24 months (3-96) and the median number of ERC sessions was 3.9 (1-10). The most common ERC indications through PAL were stones (40%) and cholangitis (30%). In 16 patients (75%), anastomotic or branched strictures were observed. The improvement of strictures via intermittent stenting and dilatation was observed in 6 patients, but no improvement was observed in 5 patients. The treatment of those 5 patients continues. In this study, the technical success was 100% and clinical success was 85%. While no mortality due to PAL-mediated ERC was observed, free wall perforation was seen in one patient who was referred to surgery.

CONCLUSION

PAL-mediated ERC procedure is a technique with high technical and clinical success and low complication rate in patients who require frequent percutaneous procedures and those with difficult access to the biliary tract.

Early laparoscopic cholecystectomy is associated with less risk of complications after the removal of common bile duct stones by endoscopic retrograde cholangiopancreatography

BACKGROUND/AIMS

Several studies recommend prompt laparoscopic cholecystectomy (LC) following endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. However, histopathological alterations in the gallbladder during this time interval and the role played by ERCP in causing these changes have not been sufficiently elucidated. To compare early period LCs with delayed LCs following common bile duct stone extraction via ERCP with regard to operation time, hospitalization period, conversion to open cholecystectomy rate, morbidity, mortality, and histopathological alterations in the gallbladder wall.

MATERIALS AND METHODS

A total of 85 patients were retrospectively divided into three groups: early period LC group (48-72 h; n=30), moderate period LC group (72 h-6 weeks; n=25), and delayed period LC group (6-8 weeks; n=30).

RESULTS

The operation time was significantly shorter, and the total number of complication rates and hospital readmission was significantly less frequent in the early period LC group (p<0.05). Ultrasound showed a significantly thicker gallbladder wall (>3 mm) in the moderate and late period LC groups than in the early period LC group (p<0.001). Culture growth was significantly higher, and fibrosis/collagen deposition in the gallbladder wall with injury to the mucosal epithelium was significantly more frequently detected by histopathological examination in the moderate and late period LC groups than in the early period LC group (p<0.05).

CONCLUSION

Early period LC following stone extraction by ERCP is associated with shorter operation time, fewer fibrotic changes in the gallbladder, and lower risk for the development of complications. Therefore, LC can be performed safely in the early period after ERCP.

On demand pancreatic stenting in chronic pancreatitis might provide good palliation of pain

BACKGROUND AND AIM

Chronic pancreatitis (CP)-related pain is a considerable problem in gastroenterology practice that frequently requires several endoscopic interventions. We aimed to investigate the efficacy of pancreatic duct stenting performed on demand, instead of at defined intervals, for the management of the CP-related pain.

METHODS

This study is a retrospective evaluation of thirteen years of data. Sixty-seven patients with CP who suffered from intractable pain were enrolled in the study. Pancreatic stenting was performed mainly with single stents according to the diameter of the pancreatic duct and width of the stricture or, less frequently, with multiple stents aiming to achieve stricture resolution. The subsequent endoscopic session was scheduled based on the patient's symptoms.

RESULTS

Overall, 65 of 67 patients underwent successful pancreatic cannulation (technical success rate 97%). Fifty-seven patients with a pancreatic stenting history were still undergoing follow-up. Of these patients, 26 patients still had pancreatic ductal stents; however, the stents were removed from 31 patients. Only 8 patients (25%) required further endoscopic or surgical intervention because of the re-emergence of pain after a median stent-free period of 17 months (3-127 months). One patient with a biliary stricture and one patient with a pancreatic mass underwent surgery. Pancreatic stents remained for a median length of 14 months (3-84 months). During the follow-up period, 55 of 65 patients became pain-free or had partial pain relief (clinical success rate 84%).

CONCLUSIONS

On demand replacement of pancreatic stent is feasible in patients with CP and it might provide a good palliation of CP-related pain.

Comparison of monopolar hemostatic forceps with soft coagulation versus hemoclip for peptic ulcer bleeding: a randomized trial (with video)

BACKGROUND AND AIMS

Although various methods are used in the treatment of peptic ulcer bleeding, there is not a standard recommended approach. The choice depends on multiple factors such as location of the ulcer, clinical experience of the endoscopist, and local facilities of the clinic. We aimed to compare the efficacy of monopolar hemostatic forceps soft coagulation (MHFSC) and hemoclips (HCs) in the treatment of peptic ulcer-related upper GI bleeding.

METHODS

The study group included patients who had GI bleeding due to Forrest 1a, 1b, and 2a gastric or duodenal ulcers within 1 year. Patients with bleeding diathesis, history of gastrectomy, pregnancy, or younger than age 18 years were excluded. The remaining were randomized to MHFSC and HC treatment groups and compared in terms of clinical and endoscopic features, initial hemostasis success rates, recurrent bleeding rates within the first 7 days, time to achieve hemostasis, length of hospitalization stay, and adverse events.

RESULTS

One hundred twelve patients were randomized to MHFSC (n = 56) and HC (n = 56) groups. There was no statistically significant difference between the groups with respect to demographic features, medications, underlying chronic diseases, location, and Forrest classification of the ulcers. The initial hemostasis success rate was 98.2% (55/56) in the MHFSC group and 80.4% (45/56) in the HC group (P = .004). Recurrent bleeding was detected in 2 patients in the MHFSC group (3.6%) and 8 patients in the HC group (17.7%; P = .04). The duration of endoscopic procedures (302 ± 87.8 vs 568 ± 140.4 seconds) and the length of hospital stay (3.50 ± 1.03 vs 4.37 ± 1.86 days) were significantly shorter in the MHFSC group. There were no adverse events in either group.

CONCLUSIONS

MHFSC is more effective in achieving initial hemostasis compared with HCs in the treatment of peptic ulcer bleeding and provides a shorter procedure time and a lower recurrent bleeding rate.

The efficacy of a computer alert programme for increasing HBV screening rates before starting immunosuppressive therapy

BACKGROUND AND AIM

Hepatitis B Virus (HBV) screening before starting immunosuppressive treatment is of vital importance in order to prevent HBV reactivation and its associated clinical consequences. Despite all recommendations by international organizations, screening rates are far below desired. The aim of this study was to assess the efficacy of a computer alert programme 'HBVision' for increasing HBV screening rates.

MATERIAL AND METHODS

'HBVision' identifies patients at risk of HBV reactivation by specific ICD-10 codes and immunosuppressive medication reports and sends sequential alert messages to screen for HBsAg, anti-HBc IgG and consult a specialist if one of them is positive. The demographic variables, treatment protocols, HBV screening and consultation rates of oncology and hematology patients who started immunosuppressive treatments within one year before (control group) and after "HBVision" (study group) were retrospectively compared.

RESULTS

HBsAg and anti-HBc IgG screening rates (68.6% and 13.1%, respectively) were significantly higher in the study group (n=602) compared to control group (n=815) (55% and 4.3%, respectively) (p<0.001, for both). Subgroup analysis revealed significant improvements in the screening rates of HBsAg (65.8%) and anti-HBc IgG (5.1%) in oncology patients (p<0.001), anti-HBc IgG (89.1%) in hematology patients (p<0.001).

CONCLUSION

The computer alert programme significantly increased HBV screening rates before starting immunosuppressive treatments, however the results were still below ideal. Additional efforts, such as modifying the computer programme according to feedbacks, are probably needed.

Wire-guided cannulation over a pancreatic stent method increases the need for needle-knife precutting ın patients with difficult biliary cannulations

BACKGROUND AND AIMS

Cannulation of the major papilla can be problematic, and selective biliary cannulation may fail in up to 18% of cases. Various techniques, such as double-guidewire technique (DGWT), wire-guided cannulation over a pancreatic stent (WGC-PS), the precut endoscopic sphincterotomy (needle-knife precutting technique (NKP), and transpancreatic septostomy have been used to improve the success rate of biliary cannulation. We conducted a prospective, randomized study in order to compare the biliary cannulation success rates of DGWT and WGC-PS techniques in patients with inadvertent passage of guidewire to the pancreatic duct.

METHODS

A total of 100 patients were included in the study and randomized to DGWT (n = 50) or WGC-PS (n = 50) groups. The primary outcome was successful selective cannulation, defined as deep cannulation with selective injection of radiographic contrast material into the common bile duct within 5 minutes by DGW or WGC-PS techniques without performing precut sphincterotomy.

RESULTS

Successful selective cannulation was achieved in 45 patients in the DGWT group (90%) and in 27 patients in the WGC-PS group (54%) (P < .001). Five patients (10%) in the DGWT group and 23 (46%) in the WGC-PS group required NKP for biliary access (P < .001). The overall cannulation rate was 98% for DGWT and 98% for WGC-PS (P = 1.00).

CONCLUSIONS

In patients with unintentional passage of a guidewire into the pancreatic duct during biliary cannulation attempts, the WGC-PS technique significantly increased the need for NKP compared with DGWT.

Biliary endoscopic sphincterotomy: Techniques and complications

Biliary endoscopic sphincterotomy (EST) refers to the cutting of the biliary sphincter and intraduodenal segment of the common bile duct following selective cannulation, using a high frequency current applied with a special knife, sphincterotome, inserted into the papilla. EST is either used solely for the treatment of diseases of the papilla of Vater, such as sphincter of Oddi dysfunction or to facilitate subsequent therapeutic biliary interventions, such as stone extraction, stenting, etc. It is a prerequisite for biliary interventions, thus every practitioner who performs endoscopic retrograde cholangiopancreatography needs to know different techniques and the clinical and anatomic parameters related to the efficacy and safety of the procedure. In this manuscript, we will review the indications, contraindications and techniques of biliary EST and the management of its complications.

Risk factors for morbidity in walled-off pancreatic necrosis and performance of continuous postoperative lavage: A single-center experience

BACKGROUND

The aim of this study was to evaluate the risk factors for morbidity in cases of walled-off pancreatic necrosis (WOPN) and the performance of continuous postoperative lavage (CPL) for patients who demonstrated resistance to a minimally invasive approach.

METHODS

The study enrolled 19 of 28 consecutive patients with WOPN who underwent surgical treatment or an endoscopic necrosectomy at Sakarya University Education and Research Hospital. The patients were divided into 2 groups according to the length of time from the first diagnosis of acute pancreatitis (AP) (Group 1, n=19) to preoperation or endoscopic necrosectomy (Group 2) (n=19). All of the cases were retrospectively evaluated and compared in terms of demographic features, operative features, and complications.

RESULTS

No statistically significant difference was found between the number of complications or the duration of hospital stay in terms of age, body mass index, size of the walled-off pancreatic necrosis, American Society of Anesthesiologists score, Ranson's criteria, operation time, and duration from AP to endoscopic necrosectomy or operation (p>0.05). Performance of an endoscopic necrosectomy was determined to be correlated with a decrease in the number of complications (B=-0.626, 95% confidence interval [CI]: -0.956 to -0.296; p<0.001), and when a high neutrophil-to-lymphocyte ratio (NLR) was detected at first admission, the number of complications was greater (B=0.032, 95% CI: 0.009-0.055; p=0.01). Reproduction in a culture and male gender were found to be risk factors for a prolonged hospital stay (B=0.669, 95% CI: 0.365-0.973; p<0.001), (B=0.484, 95% CI: 0.190-0.778; p=0.003), respectively.

CONCLUSION

CPL is a safe and effective surgical treatment approach for WOPN. Reproduction in a culture, male gender, and a high NLR on first admission and a negative or not-available endoscopic necrosectomy were determined to be risk factors for a poor prognosis.

Endoscopic papillectomy of benign ampullary lesions: Outcomes from a multicenter study

BACKGROUND/AIMS

Endoscopic papillectomy (EP) has emerged as an alternative to surgery in the management of ampullary lesions. The aim of this study is to evaluate feasibility, efficacy, safety, outcome, and impact of EP in the management of benign ampullary lesions.

MATERIALS AND METHODS

This is a multicenter, retrospective study of 44 patients who had EP of benign ampullary lesions.

RESULTS

Over the 11-year period, 44 (55.7%) of 79 patients underwent EP for benign ampullary lesions. Complete resection was achieved in 40 patients (91%). An underlying adenocarcinoma was the only risk factor for incomplete resection. Twenty-eight lesions (63.6%) were resected en-bloc and 16 lesions (36.4%) were resected in piecemeal fashion. Post-papillectomy histopathologic diagnoses were tubular adenoma in 14 patients (32%), invasive adenocarcinoma in 9 patients (20.5%), tubullovillous adenoma in 7 patients (16%), tubullovillous adenoma with carcinoma limited to the mucosal layer in 5 patients (11.3%), adenoma with high-grade dysplasia in 4 patients (9%), neuroendocrine tumor in 1 patient (2.3%), ganglioneuroma in 1 patient (2.3%), hamartomatous polyp in 1 patient (2.3%), adenofibroma in 1 patients (2.3%), and Brunner gland hyperplasia in 1 patient (2.3%). Seven (15.9%) procedure-related complications occurred: 3 (6.8%) bleeding, 2 (4.5%) pancreatitis, 1 (2.3%) abdominal pain, and 1 (2.3%) stent migration to the pancreatic duct. Seven patients (17%) had recurrence.

CONCLUSION

Endoscopic papillectomy is a safe and effective method and can be considered as a first-line approach in patients with benign ampullary lesions with intent for cure. It also allows for correct histological diagnosis and staging.

Two Cases of Pericarditis Associated with Inflammatory Bowel Disease

Extraintestinal manifestations are common complications of inflammatory bowel disease (IBD) whereas the association of cardiac disease with IBD is rarely reported. Cardiac manifestations may be diagnosed before, concomitantly or after the diagnosis of the specific type of inflammatory bowel disease. Pericarditis and myocarditis are potentially serious complications. This extraintestinal manifestation developed in one patient concomitantly with onset of intestinal disease. One patient had ulcerative colitis (UC), while other had Crohn’s disease (CD). Indomethacin was effective in one and the other patient required prednisone in addition. Chest symptoms in patients with inflammatory bowel disease should be evaluated to exclude myopericardial disease.

Endoscopic treatment of biliary complications after living donor liver transplantation in a high volume transplant center in Turkey; a single-center experience

BACKGROUND AND AIM

Biliary complications are an important cause of mortality and morbidity after living donor liver transplantation (LDLT). We present our endoscopic treatment results after LDLT as a single center with high volume.

METHODS

Patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) after LDLT between 2005 and 2015 were included. Clinical data included patient demographics, ERCP indications (stricture or leak), and treatment outcomes, including need for percutaneous and surgical interventions.

RESULTS

ERCP was performed in 446 (39.2%) patients with duct-to-duct anastomosis of 1136 LDLT patients. The most common biliary complication was stricture ± stone (70.6%, 315/446). Stricture and leak occurred in 60 (13.4%) patients. Only biliary leak was found in 40 (8.9%) patients. Our endoscopic treatment success rate in patients with biliary stricture after LDLT was 65.1%. Overall endoscopic success rates in our patients were 55.0% in patients with both leak and stricture, and only leak. In all, our percutaneous transhepatic biliary interventions (PTBI) and ERCP success rate was 90.6% in patients with biliary complications after LDLT.

CONCLUSIONS

Endoscopic treatments are highly effective for biliary complications after LDLT. Effective use of percutaneous interventions in collaboration with endoscopic treatments significantly reduces the need for surgical treatment.

A novel technique for the endoscopic treatment of complete biliary anastomosis obstructions after liver transplantation: through-the-scope magnetic compression anastomosis

BACKGROUND AND AIMS

Magnetic compression anastomosis is a rescue technique for recanalization of complete biliary strictures. Here, we present magnetic compression anastomosis with novel through-the-scope magnets in patients with complete duct-to-duct anastomosis obstruction after liver transplantation.

METHODS

The magnets were 2 and 2.4 mm in diameter, with a hole at the center for inserting a guidewire. One of the magnets was advanced through the scope up to the distal site of the stricture by using a 7F pusher. The other magnet was pushed percutaneously through the 10F sheath. The procedure was terminated when the magnets were approximated or properly aligned. Recanalization was followed by percutaneous cholangiography. Patients underwent multiple plastic stenting after recanalization was achieved.

RESULTS

Nine patients with a stricture length of less than 1 cm, a stump in the donor bile ducts close to the stricture, and proper positioning of the bile duct stumps, underwent magnetic compression anastomosis. Seven patients had a live donor-related liver transplantation. The mean stricture time was 24.1 ± 17.1 months. The mean stricture length was 4.0 ± 1.2 mm. Recanalization was achieved in 7 patients (77%) after a mean recanalization time of 8.1 ± 4.7 days. There was no recurrence after 4.8 ± 3.8 months of stent-free follow-up. No adverse events were observed.

CONCLUSIONS

The through-the-scope magnet procedure was effective in the recanalization of complete anastomotic biliary obstructions after liver transplantation in a selected group of patients with a short stricture length and an appropriate anatomy.

Tetanus in adults: results of the multicenter ID-IRI study

Tetanus is an acute, severe infection caused by a neurotoxin secreting bacterium. Various prognostic factors affecting mortality in tetanus patients have been described in the literature. In this study, we aimed to analyze the factors affecting mortality in hospitalized tetanus patients in a large case series. This retrospective multicenter study pooled data of tetanus patients from 25 medical centers. The hospitals participating in this study were the collaborating centers of the Infectious Diseases International Research Initiative (ID-IRI). Only adult patients over the age of 15 years with tetanus were included. The diagnosis of tetanus was made by the clinicians at the participant centers. Izmir Bozyaka Education and Research Hospital's Review Board approved the study. Prognostic factors were analyzed by using the multivariate regression analysis method. In this study, 117 adult patients with tetanus were included. Of these, 79 (67.5%) patients survived and 38 (32.5%) patients died. Most of the deaths were observed in patients >60 years of age (60.5%). Generalized type of tetanus, presence of pain at the wound area, presence of generalized spasms, leukocytosis, high alanine aminotransferase (ALT) and C-reactive protein (CRP) values on admission, and the use of equine immunoglobulins in the treatment were found to be statistically associated with mortality (p < 0.05 for all). Here, we describe the prognostic factors for mortality in tetanus. Immunization seems to be the most critical point, considering the advanced age of our patients. A combination of laboratory and clinical parameters indicates mortality. Moreover, human immunoglobulins should be preferred over equine sera to increase survival.

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.

The Detection of Cholangiocarcinoma in Primary Sclerosing Cholangitis Patients: Single Center Experience

PURPOSE

Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease. Cholangiocarcinoma (CCA) is one of the feared complications of PSC. In our study, we aim to establish the success of brush cytology and CA 19-9 in putting the diagnosis of CCA.

METHODS

The data of 30 PSC patients was retrospectively screened whom had brush cytology performed due to dominant strictures. The definitive diagnosis was established by histopathological examination or via radiological/clinic follow-up for at least 12 months.

RESULTS

A total of four patients were excluded from the study. Twenty-six patients diagnosed with PSC, six of which were also diagnosed with CCA, were included in the study. The sensitivity and the specificity of the brush cytology in the diagnosis of CCA in PSC patients were 66.7 and 95%, respectively. CA 19-9 had high correlation with bilirubin level. The optimal level of CA 19-9 in the diagnosis of CCA was determined to be 138.5 U/ml. Superiority of Ramage scoring over CA 19-9 in the diagnosis of CCA in PSC patients was not established (sensitivity and specificity were 50%, 94.7% and 83.3%, 85%, respectively).

CONCLUSION

Brush cytology has moderate sensitivity in differentiating strictures in PSC patients. CA 19-9 has high sensitivity but bilirubin level can affect the CA 19-9. Therefore, advanced techniques and parameters are needed for detecting CCA in PSC patients.

Spread of carbapenem-resistant international clones of Acinetobacter baumannii in Turkey and Azerbaijan: a collaborative study

Epidemic clones of Acinetobacter baumannii, described as European clones I, II, and III, are associated with hospital epidemics throughout the world. We aimed to determine the molecular characteristics and genetic diversity between European clones I, II, and III from Turkey and Azerbaijan. In this study, a total of 112 bloodstream isolates of carbapenem-resistant Acinetobacter spp. were collected from 11 hospitals across Turkey and Azerbaijan. The identification of Acinetobacter spp. using conventional and sensitivity tests was performed by standard criteria. Multiplex polymerase chain reaction (PCR) was used to detect OXA carbapenemase-encoding genes (bla OXA-23-like, bla OXA-24-like, bla OXA-51-like, and bla OXA-58-like). Pulsed-field gel electrophoresis (PFGE) typing was used to investigate genetic diversity. The bla OXA-51-like gene was present in all 112 isolates, 75 (67 %) carried bla OXA-23-like, 7 (6.2 %) carried bla OXA-58-like genes, and 5 (4.5 %) carried bla OXA-24-like genes. With a 90 % similarity cut-off value, 15 clones and eight unique isolates were identified. The largest clone was cluster D, with six subtypes. Isolates from clusters D and I were widely spread in seven different geographical regions throughout Turkey. However, F cluster was found in the northern and eastern regions of Turkey. EU clone I was grouped within J cluster with three isolates found in Antalya, Istanbul, and Erzurum. EU clone II was grouped in the U cluster with 15 isolates and found in Kayseri and Diyarbakır. The bla OXA-24-like gene in carbapenemases was identified rarely in Turkey and has been reported for the first time from Azerbaijan. Furthermore, this is the first multicenter study in Turkey and Azerbaijan to identify several major clusters belonging to European clones I and II of A. baumannii.

Managing atypical and typical herpetic central nervous system infections: results of a multinational study

There have been many studies pertaining to the management of herpetic meningoencephalitis (HME), but the majority of them have focussed on virologically unconfirmed cases or included only small sample sizes. We have conducted a multicentre study aimed at providing management strategies for HME. Overall, 501 adult patients with PCR-proven HME were included retrospectively from 35 referral centres in 10 countries; 496 patients were found to be eligible for the analysis. Cerebrospinal fluid (CSF) analysis using a PCR assay yielded herpes simplex virus (HSV)-1 DNA in 351 patients (70.8%), HSV-2 DNA in 83 patients (16.7%) and undefined HSV DNA type in 62 patients (12.5%). A total of 379 patients (76.4%) had at least one of the specified characteristics of encephalitis, and we placed these patients into the encephalitis presentation group. The remaining 117 patients (23.6%) had none of these findings, and these patients were placed in the nonencephalitis presentation group. Abnormalities suggestive of encephalitis were detected in magnetic resonance imaging (MRI) in 83.9% of the patients and in electroencephalography (EEG) in 91.0% of patients in the encephalitis presentation group. In the nonencephalitis presentation group, MRI and EEG data were suggestive of encephalitis in 33.3 and 61.9% of patients, respectively. However, the concomitant use of MRI and EEG indicated encephalitis in 96.3 and 87.5% of the cases with and without encephalitic clinical presentation, respectively. Considering the subtle nature of HME, CSF HSV PCR, EEG and MRI data should be collected for all patients with a central nervous system infection.

The Prevalence of Barrett Esophagus Diagnosed in the Second Endoscopy: A Retrospective, Observational Study at a Tertiary Center

At present, we do not know the exact prevalence of Barrett esophagus (BE) developing later in patients without BE in their first endoscopic screening. The purpose of this study was to determine the prevalence of BE on the second endoscopic examination of patients who had no BE in their first endoscopic examination.The data of the patients older than 18 years who had undergone upper gastrointestinal system endoscopy more than once at the endoscopy unit of our clinic during the last 6 years were retrospectively analyzed.During the last 6 years, 44,936 patients had undergone at least one endoscopic examination. Among these patients, 2701 patients who had more than one endoscopic screening were included in the study. Of the patients, 1276 (47.3%) were females and 1425 (52.7%) were males, with an average age of 54.9 (18-94) years. BE was diagnosed in 18 (0.66%) of the patients who had no BE in the initial endoscopic examination. The patients with BE had reflux symptoms in their medical history and in both endoscopies, they revealed a higher prevalence of lower esophageal sphincter laxity, hiatal hernia, and reflux esophagitis when compared to patients without BE (P < 0.001).Our study showed that in patients receiving no diagnosis of BE on their first endoscopic examination performed for any reason, the prevalence of BE on their second endoscopy within 6 years was very low (0.66%).

Comparison of thiol/disulphide homeostasis parameters in patients with COPD, asthma and ACOS

OBJECTIVE

Chronic obstructive pulmonary disease (COPD), asthma and asthma-COPD overlap syndrome (ACOS) are obstructive pulmonary disorders with different manifestations. Status of oxidation in tissues is important in obstructive pulmonary disorders. Smoking, acute exacerbations of COPD and asthma were associated with a marked imbalance in oxidant or antioxidant status due to increased oxidative stress in tissues and blood. Oxidative conditions may cause a reversible formation of mixed disulphides among protein thiol groups. The aim of this study was to compare parameters related with thiol/disulphide homeostasis in patients with COPD, asthma and ACOS.

PATIENTS AND METHODS

Patients (n= 135, 69 females, 66 males) who were referred with a diagnosis of COPD, asthma or ACOS were included in the study. Thiol/ disulphide homeostasis parameters in blood were analysed by a newly established method that measures the exact thiol/ disulphide status in the body.

RESULTS

The patients with COPD, asthma or ACOS were similar for demographic parameters other than age and number of cigarettes smoked. Measured thiol/disulphide homeostasis parameters were similar among these patient groups. When these biochemical measurements were adjusted for age and number of cigarettes by using regression analysis, similarity for thiol/disulphide homeostasis parameters among patient groups persisted.

CONCLUSIONS

To best of our knowledge, this is the first study to compare thiol/disulphide homeostasis parameters in COPD, asthma and ACOS patients. Similarity of thiol/disulphide homeostasis parameters among these patient groups supports the current view of Dutch hypothesis that COPD, asthma and ACOS share similar pathophysiological features but display different clinical manifestations.
