OBJECTIVE: Pain associated with colonoscopy is a major burden for patients. We investigated modifiable factors associated with patient-reported pain during and after colonoscopy. DESIGN: This cross-sectional analysis included database records from 23 centres participating in a population-based colonoscopy screening programme in Poland. Colonoscopies were performed under three sedation modalities: none, benzodiazepine-opioid sedation or propofol sedation. We used Gastronet (a validated tool) to assess patients' pain during and after colonoscopy; pain was scored on a four-point scale (no, little, moderate or severe pain), with moderate to severe defined as painful. We used multivariate logistic regression models to estimate ORs for painful colonoscopy and calculated risk-adjusted ratios of painful colonoscopies per endoscopist and compared it to the mean rate. RESULTS: Of 35 216 screening colonoscopies in 2014 and 2015 included in our study, 22 725 (64.5%) patients returned valid Gastronet questionnaires. The proportion of examinations described as causing pain during (after) the procedure was 22.5% (14.2%) for unsedated, 19.9% (13.5%) for benzodiazepine-opioid sedation and 2.5% (7.5%) for propofol sedation. Propofol sedation, higher case volume of endoscopists, newest endoscope generation and adequate bowel preparation were significantly associated with lower odds of painful colonoscopy. Pain scores after colonoscopy showed similar associations. Adjusted pain rates during and after colonoscopy varied 11 and over 23-fold, respectively, between endoscopists. CONCLUSION: We identified several independent, modifiable factors associated with pain during and after colonoscopy, of which individual endoscopist was the most important. Dedicated training should be considered to decrease variability among endoscopists.

Background and study aims Linear endoscopic ultrasound (EUS) evaluation of the pancreaticobiliary system usually requires scanning from both the stomach and the duodenum. The feasibility of assessing the complete pancreaticobiliary system from the stomach alone has not been studied. We aimed to conceptualize a system-based approach (the railroad approach) for linear pancreaticobiliary EUS (PB-EUS) and evaluate whether the pancreaticobiliary anatomy could be assessed from the stomach alone. Patients and methods Three maneuvers were conceptualized and evaluated (the alpha maneuver in the stomach, and sigma and xi maneuvers in the duodenum). The maneuvers were prospectively evaluated in 100 consecutive patients requiring PB-EUS.  Results The median procedure time for the three maneuvers was significantly higher than that for the alpha maneuver alone (12 vs. 6 minutes; P ≤ 0.001). The visualization rate of the hilum and common hepatic duct was significantly higher from the stomach than from the duodenum (100 % vs. 83.5 %; P ≤ 0.001), while rates for the head of the pancreas (100 % vs 100 %) and uncinate process (100 % vs 100 %) did not differ. The suprapancreatic common bile duct (CBD; 92 % vs 100 %; P = 0.006), retropancreatic CBD (95 % vs 100 %; P = 0.06), and pancreatic duct in the head (94 % vs 100 %; P = 0.03) were not completely visualized from the stomach, because of pancreatic calcification or shadow from the ligaments. The EUS diagnosis made from the stomach and duodenum did not differ after excluding body and tail lesions (pancreatic head neoplasms, 100 % vs 100 %; CBD stone, 100 % vs 84.6 %; pancreatic cysts in the head, 83.3 % vs 83.3 %, respectively). Conclusions Adequate anatomical and diagnostic information on the pancreaticobiliary system may be acquired by EUS scanning from the stomach alone and with a shorter procedure time.

Vascular diseases account for a significant proportion of abdominal pathology and represent a common referral source for abdominal ultrasonographic examinations. B-mode, color Doppler, and spectral Doppler analyses are well-established in the evaluation of abdominal blood vessels although they may occasionally be limited by lower sensitivity for slow flow visualization or the deeper location of abdominal vascular structures. The introduction of microbubbles as ultrasonographic contrast agents has rendered contrast-enhanced ultrasound (CEUS), a valuable complementary ultrasonographic technique, which is capable of addressing clinically significant problems and guiding patient management. The purpose of this pictorial review is to analyze the use of CEUS in the evaluation of abdominal vascular pathology and illustrate such applications by presenting representative images. Pathology discussed includes abdominal aortic aneurysm, post-endovascular treatment aorta, portal vein thrombosis, abdominal vascular trauma, and organ transplantation along with its complications.

... surgery for gastric cancer is a safe and feasible alternative to laparoscopic surgery and it can be successfully used to treat gastric cancer in patients with SIT with multiple anatomic variations. As exemplified by our case, SIT might be accompanied by multiple anatomic variations. Detailed preoperative detailed imaging of the blood vessels and gastrointestinal tract is useful in these patients.

BACKGROUND AND AIMS: Endoscopic ultrasound-guided transmural drainage using lumen apposing metal stents (LAMSs) is becoming a popular and promising therapeutic approach for drainage of intra-abdominal fluid collections. There has been an increasing number of studies evaluating LAMS for drainage of pancreatic pseudocysts (PP), walled-off pancreatic necrosis (WOPN), and gallbladder (GB) drainage. The aim of this meta-analysis is to analyze the literature to date regarding the clinical success, technical success, and adverse events of LAMS in treatment of pancreatic fluid collections and GB drainage. METHODS: A comprehensive search of multiple literature databases through November 2016 was performed. Human studies with at least 10 subjects that examined the clinical success, technical success, and adverse events of LAMS in treating PP, WOPN, and GB drainage were included. RESULTS: A total of 993 patients (608-WOPN; 204-PP; 181-GB drainage) underwent drainage from 20 trials. For drainage of WOPN, the pooled technical success was 98.9% [95% confidence interval (CI): 98.2% to 99.7%] and clinical success was 90% (95% CI: 87% to 93%) (τ=0.001). For drainage of PP, the pooled technical success was 97% (95% CI: 95% to 99%) and clinical success was 98% (95% CI: 96% to 100%), (τ=0.001). For GB drainage, the pooled technical success was 95% (95% CI: 91% to 99%) and clinical success was 93% (95% CI: 90% to 97%), (τ=0.001). Total adverse events occurred in 11% of patients with higher complication rates observed in GB drainage. There was no evidence of publication bias in this meta-analysis. CONCLUSIONS: Endoscopic ultrasound-guided transmural drainage using LAMS is becoming a widely accepted therapeutic approach for the treatment of PP, WOPN, and GB drainage with high clinical and technical success rates and acceptable adverse events. Further prospective randomized trials reporting long-term clinical efficacy and cost-effectiveness are needed to validate LAMS as a therapeutic modality for pancreatic and GB collections.

CONTEXT: Endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) by bilateral or unilateral approach is widely used in palliative abdominal pain management in pancreatic cancer patients, but the analgesic effect and relative risks of the two different puncture routes remain controversial. OBJECTIVES: The aim of this systematic review was to evaluate the analgesic efficacy and safety of bilateral EUS-CPN compared with unilateral EUS-CPN. METHODS: An electronic database search was performed for randomized controlled trials comparing bilateral and unilateral approaches of EUS-CPN using the Pubmed, Cochrane Library, Web of Science, Google Scholar, and CNKI databases. Meta-analysis was performed using RevMan 5.3 after screening and methodological evaluation of the selected studies. Outcomes included pain relief, treatment response, analgesic reduction, complications, and quality of life (QOL). RESULTS: Six eligible studies involving 437 patients were included. No significant difference was found in short-term pain relief [SMD = 0.31, 95% CI (- 0.20, 0.81), P = 0.23] and response to treatment [RR = 0.99, 95% CI (0.77, 1.41), P = 0.97] between the bilateral and unilateral neurolysis groups. However, only the bilateral approach was associated with a statistically significant reduction in the postoperative use of analgesics [RR = 0.66, 95% CI (0.47, 0.94), P = 0.02] compared to the unilateral approach. A descriptive analysis was performed for complications and QOL. CONCLUSION: The short-term analgesic effect and general risk of bilateral EUS-CPN are comparable with those of unilateral EUS-CPN, but our evidence supports the conclusion that the bilateral approach significantly reduces postoperative analgesic use.

Of 101,590 shockwave lithotripsy patients, 23% and 16% had no postoperative imaging within 3 and 12 months, respectively. Abdominal x-ray was the most common imaging modality after either procedure type... The majority who do receive imaging undergo abdominal x-ray, precluding the ability to screen for hydronephrosis or silent obstruction in nearly 75% of ureteroscopy patients.

OBJECTIVE: Neurocutaneous syndromes are a heterogeneous group of multisystemic disorders. We review the multimodality imaging findings in the disorders with a propensity for intraabdominal disease. We highlight more recently recognized disease patterns and discuss imaging surveillance optimization. CONCLUSION: Knowledge of varied intraabdominal phenotypic expressions can increase diagnostic rates. Limitation of radiation dose must be considered in screening this tumor-prone population. Early detection of neoplastic findings is critical for morbidity and mortality reduction.

BACKGROUND: Various fat depots including visceral (VAT), subcutaneous adipose tissue (SAT) or liver fat content (LFC) were supposed to have different influences on various entities including adipokine levels as well as insulin resistance/sensitivity. Therefore, the aim of the study was to investigate the associations of SAT, VAT and LFC with the levels of leptin and vaspin as well as insulin resistance in a general non-diabetic population. METHODS: In total, 1825 participants of the Study of Health in Pomerania were characterized according to body fat compartments and LFC determined by magnetic resonance imaging. Of those subjects, insulin resistance (HOMA-IR) and insulin sensitivity ([ISI(comp)) were determined in 981 participants and adipokines were assessed in 698 using enzyme-linked immunosorbent assay. Analyses of variance and linear regression models adjusted for age, sex, smoking, height, physical inactivity and alcohol consumption were used for analysis. RESULTS: Using the residual method to assess independently the effect of the various fat depots, a strong positive association of SAT (beta per standard deviation (s.d.) increase 0.54 (95% confidence interval (CI) 0.47-0.60)) but not VAT (beta 0.01 (95% CI -0.08 to 0.09)) and LFC (beta 0.01 (95% CI -0.06 to 0.08)) with log2-leptin levels was found independent of the HOMA-IR status. Moreover, a positive association of LFC (beta 0.17 (95% CI 0.07-0.26)) with log2-vaspin levels becomes apparent, which were mostly driven by subjects with a low HOMA-IR. With respect to HOMA-IR and ISI(comp) index, pronounced positive and inverse associations to all fat markers were revealed, respectively, with the strongest relation found for SAT and LFC. CONCLUSIONS: SAT and LFC were identified as predominant sites associated with leptin and vaspin levels, respectively. Residual analysis pointed towards a general adverse effect of disproportional triglyceride storage across physiological despots, in particular in ectopic sides such as the liver, with markers of insulin resistance.International Journal of Obesity advance online publication, 19 September 2017; doi:10.1038/ijo.2017.187.
