RESUMO
BACKGROUND: Studies on the effect of computer-aided detection (CAD) in a daily clinical screening and surveillance colonoscopy population practice are scarce. The aim of this study was to evaluate a novel CAD system in a screening and surveillance colonoscopy population. METHODS: This multicentre, randomised, controlled trial was done in ten hospitals in Europe, the USA, and Israel by 31 endoscopists. Patients referred for non-immunochemical faecal occult blood test (iFOBT) screening or surveillance colonoscopy were included. Patients were randomomly assigned to CAD-assisted colonoscopy or conventional colonoscopy; a subset was further randomly assigned to undergo tandem colonoscopy: CAD followed by conventional colonoscopy or conventional colonoscopy followed by CAD. Primary objectives included adenoma per colonoscopy (APC) and adenoma per extraction (APE). Secondary objectives included adenoma miss rate (AMR) in the tandem colonoscopies. The study was registered at ClinicalTrials.gov, NCT04640792. FINDINGS: A total of 916 patients were included in the modified intention-to-treat analysis: 449 in the CAD group and 467 in the conventional colonoscopy group. APC was higher with CAD compared with conventional colonoscopy (0·70 vs 0·51, p=0·015; 314 adenomas per 449 colonoscopies vs 238 adenomas per 467 colonoscopies; poisson effect ratio 1·372 [95% CI 1·068-1·769]), while showing non-inferiority of APE compared with conventional colonoscopy (0·59 vs 0·66; p<0·001 for non-inferiority; 314 of 536 extractions vs 238 of 360 extractions). AMR in the 127 (61 with CAD first, 66 with conventional colonoscopy first) patients completing tandem colonoscopy was 19% (11 of 59 detected during the second pass) in the CAD first group and 36% (16 of 45 detected during the second pass) in the conventional colonoscopy first group (p=0·024). INTERPRETATION: CAD increased adenoma detection in non-iFOBT screening and surveillance colonoscopies and reduced adenoma miss rates compared with conventional colonoscopy, without an increase in the resection of non-adenomatous lesions.

PURPOSE: Obesity and pregnancy are strictly related: on the one hand, obesity-one of the most common comorbidities in women of reproductive age-contributes to infertility and obesity-related pregnancy complications, whereas pregnancy is a condition in which, physiologically, the pregnant woman undergoes weight gain. Endoscopic sleeve gastroplasty (ESG) may be used for the treatment of obesity in women of childbearing age. MATERIALS AND METHODS: A retrospective analysis was conducted to evaluate weight trajectories, the evolution of obesity-related comorbidities, and lifestyle modification in women who became pregnant after ESG. A comparison was made between childbearing-age women who became pregnant after ESG and non-pregnant women. RESULTS: A total of 150 childbearing-age women underwent ESG at a large tertiary medical center. Of these, 11 patients (33.4 ± 6.2 years) became pregnant after the procedure, following a mean time interval of 5.5 ± 3.9 months. Three women (two affected by polycystic ovary syndrome) reported difficulty getting pregnant before undergoing ESG. The mean preconception BMI was 31.9±4.0 kg/m2 (-7.24 ± 4.0 kg/m2 after ESG). Total body weight loss (TBWL, %) was 18.08 ± 8.00, 11.00 ± 11.08, and 12.08 ± 8.49, at the beginning of pregnancy, at the delivery, and at the first follow-up (19.6 ± 7.8 months after ESG). TBWL of at least 5% was achieved before pregnancy in all patients (73% reached a TBWL ≥ 10%). No significant differences in weight loss and QoL were found between the pregnancy and non-pregnancy groups up to 24 months after ESG. CONCLUSIONS: Endoscopic sleeve gastroplasty allows for adequate weight loss before and after pregnancy in patients with obesity.

BACKGROUND & AIMS: Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is emerging as a safe and effective treatment for pancreatic neuroendocrine tumors. We aimed to compare EUS-RFA and surgical resection for the treatment of pancreatic insulinoma (PI). METHODS: Patients with sporadic PI who underwent EUS-RFA at 23 centers or surgical resection at 8 high-volume pancreatic surgery institutions between 2014 and 2022 were retrospectively identified and outcomes compared using a propensity-matching analysis. Primary outcome was safety. Secondary outcomes were clinical efficacy, hospital stay, and recurrence rate after EUS-RFA. RESULTS: Using propensity score matching, 89 patients were allocated in each group (1:1), and were evenly distributed in terms of age, sex, Charlson comorbidity index, American Society of Anesthesiologists score, body mass index, distance between lesion and main pancreatic duct, lesion site, size, and grade. Adverse event (AE) rate was 18.0% and 61.8% after EUS-RFA and surgery, respectively (P < .001). No severe AEs were observed in the EUS-RFA group compared with 15.7% after surgery (P < .0001). Clinical efficacy was 100% after surgery and 95.5% after EUS-RFA (P = .160). However, the mean duration of follow-up time was shorter in the EUS-RFA group (median, 23 months; interquartile range, 14-31 months vs 37 months; interquartile range, 17.5-67 months in the surgical group; P < .0001). Hospital stay was significantly longer in the surgical group (11.1 ± 9.7 vs 3.0 ± 2.5 days in the EUS-RFA group; P < .0001). Fifteen lesions (16.9%) recurred after EUS-RFA and underwent a successful repeat EUS-RFA (11 patients) or surgical resection (4 patients). CONCLUSION: EUS-RFA is safer than surgery and highly effective for the treatment of PI. If confirmed in a randomized study, EUS-RFA treatment can become first-line therapy for sporadic PI.

BACKGROUND: Peroral endoscopic myotomy (POEM) is rapidly becoming the procedure of choice for treating esophageal achalasia. In most centers, contrast-enhanced swallow studies (CESS) are routinely performed postoperatively to confirm mucosal integrity. The aim of this study was to determine the necessity of performing these studies routinely after POEM. METHODS: A retrospective review of a prospectively maintained database of patients who underwent POEM between December 2012 and November 2020 was performed. All patients underwent a CESS on the first postoperative day. Medical records including vital signs, complete blood count, and POD-1 CESS were evaluated. RESULTS: One hundred thirty-four consecutive patients were included in the study. Sixty-nine (51.49%) CESS showed abnormal findings; while most findings did not change the postoperative course, five (7.2%) demonstrated tunnel leaks, which did alter the overall management. Screening patients for fever, tachycardia, or leukocytosis on POD-1 had a 100% sensitivity and a 62% specificity for finding a clinically significant complication on CESS. CONCLUSIONS: The study findings suggest that performing routine contrast-enhanced swallow studies on all patients is not necessary following POEM, as leaks can be screened for by clinical or laboratory abnormalities. Herein, we propose an algorithm based on objective measurable findings for the selection of patients who should undergo CESS.

Purpose: APC I1307K has a higher prevalence among Ashkenazi Jews (AJ), and a two-fold increased risk for colorectal cancer (CRC) compared to non-Jewish populations. We assessed CRC and extracolonic malignancies among I1307K carriers from AJ and non-AJ whites (NAW). Methods: We compared the rate of I1307K in cancer patients who underwent germline genetic testing via a multi-gene panel with healthy subjects retrieved from the gnomAD database. Cases undergoing testing were not selected and testing was undertaken through a commercial laboratory. Results: Overall, 586/7624 (7.6%) AJ with cancer carried I1307K compared to 342/4918 (6.9%) in the AJ control group (p = NS). In the NAW, 318/141,673 (0.2%) cancer patients and 73/58,918 (0.1%) controls carried the variant [OR = 1.8, (95% CI 1.41−2.35), p < 0.001]. I1307K in NAW was associated with an increased risk of CRC [OR = 1.95, (95% CI 1.39−2.73), p < 0.01], melanoma [OR = 2.54, (95% CI 1.57−3.98)], breast [females, OR = 1.73, (95% CI 1.18−2.65), p < 0.01], and prostate cancer [males, OR = 2.42, (95% CI 1.45−3.94), p < 0.01]. Among AJ, the variant increased the risk for CRC [OR = 1.67, (95% CI 1.36−2.05), p < 0.001] and renal cancer [OR = 1.64, (95% CI 1.04−2.47)]. AJ men had a higher risk for any cancer [OR = 1.32, (95% CI 1.05−1.66), p < 0.05] and melanoma [OR = 2.04, (95% CI 1.24−3.22); p < 0.05]. Conclusions: This is the most extensive study to date conducted on I1307K carriers, although it is amenable to selection bias. NAW carrying I1307K had a higher risk of any cancer and several specific cancer types, whereas AJ carrying the variant had a risk for only a few select cancers. Our data add to the research base on I1307 carriers concerning future risk management.
RESUMO
Backgrounds/Aims: The soft texture of the pancreas parenchyma may influence the incidence of pancreatic leakage after pancreaticoduodenectomy (PD). One possible method to assess pancreatic texture and atrophy, is via computed tomography (CT) scan of the abdomen. The purpose of our study was to evaluate the relation between the preoperative CT scan and the incidence of pancreatic fistula after PD. Methods: A retrospective single-center study including patients who underwent PD for a benign and malignant tumor of the periampullary region between the years 2000 and 2016. Demographic and imaging data were analysed and a correlation with the post-operative leak was evaluated. Results: Pancreatic leak was documented in 34 out of 154 (22.1%) patients. All the leakage cases occurred in the preserved pancreas group (33.1% of the total preserved pancreas group alone). No leak was documented in the atrophic pancreas group. This difference between the two groups was found to be statistically significant (p ≤ 0.00001). Conclusions: Atrophic pancreas in the preoperative CT scan may be protective against leakage after PD. These findings may help the surgeon to risk stratify patients accordingly. In addition, the findings suggest that patients with a preserved pancreas may require more protective methods to prevent leakage.
RESUMO
Background and Aims: There is conflicting evidence regarding the association between proton pump inhibitors (PPI) and the risk of acquisition and severity of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Aim: To evaluate the association between PPI exposure and infection and development of severe disease in patients infected with SARS-CoV2in a large population-based historical cohort. Methods: Data were extracted from a health maintenance organization database in Israel that insures over 1,200,000 individuals from across the country. All patients who underwent SARS-CoV-2 testing between March and November 2020 were included. Logistic regression and matched analyses were used to compare patients prescribed and exposed to PPIs to those not prescribed PPIs regarding SARS-CoV-2 positivity. In addition, among SARS-CoV-2 positive patients (n = 44,397) the likelihood of developing severe disease, defined by a composite endpoint of death, ICU admission and prolonged hospitalization, was compared in those exposed and not exposed to PPIs. Results: Among 255,355 adult patients who underwent SARS-CoV-2 testing by PCR, 44,397 (17.4%) were positive for SARS-CoV-2 and 12,066 (4.7%) patients were prescribed PPIs in the 3 months before testing. In a multivariable logistic regression model controlling for age, gender, smoking status, BMI, diabetes mellitus, hypertension, COPD, history of ischemic heart disease and fasting blood glucose (FBG) levels, no significant association was found between PPIs and SARS-CoV-2 positivity (p = 0.09 aOR 0.94, 95% CI - 0.88-1.01). Among SARS-CoV-2 positive patients, 910 (2%) had a severe infection. Multivariate logistic regression controlling for the abovementioned confounders, showed no such association between PPIs and severe COVID-19 (p = 0.28). Elevated FBG levels were significantly associated with both PPI exposure (p < 0.001) and severe COVID-19 infection (p < 0.001). These results were reinforced by a matched analysis (n = 655 pairs). Conclusion: PPIs are spuriously associated with severe COVID-19 due to the presence of elevated FBG as a confounder. Our study accounted for the FBG levels of patients and known risk factors for severe COVID-19 infection, which may be the reason for the discrepancy in prior studies. These results may aid in understanding potential confounders when evaluating potential associations of PPIs with other respiratory or viral diseases.
RESUMO
BACKGROUND: POEM (Per Oral Endoscopic Myotomy) is rapidly becoming a valid option for surgical myotomy in achalasia patients. Several techniques to perform POEM are described, but all concentrate on the division of the circular muscle fibers in a proximal-to-distal fashion. Our aim is to present the distal-to-proximal, or the bottom-up technique using the Flush/Dual knife, which overcomes the disadvantages of the standard technique. METHODS: A retrospective study on a prospectively maintained database was performed on all patients treated by POEM in our institution. Clinical presentation, operating time, adverse events, and outcomes were studied. RESULTS: POEM was performed on 105 achalasia patients. The first 15 cases were performed using the standard technique and were compared to the next 90 cases performed using the bottom-up technique. The average preop Eckardt scores in the standard and bottom-up groups were 9.5 and 8.8, respectively, declining to 1.4 and 0.5, 3 months post myotomy (p < 0.001). The average procedure time was 111.2 min for the standard technique and 74.3 for the bottom-up technique. (p = 0.002). Perioperative adverse events included 14 instances of pneumoperitoneum, 3 tunnel leaks, and 4 patients with fever on postoperative day one. Pneumoperitoneum needing decompression and postoperative fever were more prevalent in the standard technique group. CONCLUSIONS: As POEM is becoming more common for the treatment of achalasia, refinements of the technique and instruments used are valuable. We compared our experience of the standard technique to our bottom-up technique and found the latter to be equally effective as well as safer, faster, and easier. We, therefore, suggest considering performing POEM in this technique.

Background: Achalasia may occasionally occur among women of childbearing age. Pregnancy may lead to deterioration of the disease and negatively affect maternal and perinatal outcomes. However, the impact of peroral endoscopic myotomy (POEM) on reproductive outcomes has been understudied. Methods: A retrospective study on prospectively maintained database, including women aged 18-45 who underwent POEM during 2012-2017 at a university hospital. Results: During the study period, POEM was performed in 86 patients. Of them, 23 were women of childbearing age (median age 31.9 [26.0-40.7] years). Follow-up data were available for a median of 24 [16-41] months. Treatment success (Eckardt score <3) was achieved in 22 (95.7%) women. Six (26.1%) women reported attempting to conceive after POEM. Overall, 7 post-POEM pregnancies among 5 women were encountered. All 7 pregnancies were naturally conceived with a median surgery-to-conception interval of 16 [10-21] months. The median gestational weight gain was 10 kg, and was insufficient in all pregnancies. None of the women was hospitalized during the index gestation. All pregnancies resulted in term live-birth vaginal delivery. The median neonatal birthweight was 2940 g, with only one case of a small-for-gestational age infant. Achalasia-related symptoms recurred during 2 pregnancies, with resolution following delivery. Conclusions: Pregnancy after POEM for the treatment of achalasia was associated with favorable maternal and perinatal outcomes. This data should reassure women who wish to conceive following peroral myotomy.

PURPOSE: The decreased life expectancy of MEN-1 patients is mainly related to pancreatic neuroendocrine tumors (pNETs). At best, limited data is available on the natural history of MEN-1-associated pNETs, as these tumors are rare and have a wide range of biologic behavior. Our study aims to explore the clinical course of patients with MEN-1-associated pNETs and the long-term outcomes. METHODS: This longitudinal study was conducted on the MEN-1 cohort treated at our referral center over a 22-year period (1996-2018). Relevant clinical data were retrospectively analysed. RESULTS: Among the 33 MEN-1 patients included in our study, pNETs were identified in 21 subjects with a penetrance of 48% by the age of 50. Non-functioning and functioning pNETs were diagnosed in sixteen (76%) and five (24%) patients, respectively. Two-thirds of the patients had multifocal tumors. The median number of pancreatic macroscopic lesions per individual was 4.0 ± 3.9 (range 1-8) with a mean size of 1.3 ± 2.1 cm (range 0.5-10). The metastatic rate according to the dominant pNET lesion reached 100%, 62% and 6% for tumors sized > 4 cm, 2.1-4 cm, and 1-2 cm, respectively. Over the study period, one or more therapeutic interventions for pNETs were required in 20 out of the 21 patients. pNET-related metastatic complication was the main cause of death within this MEN-1 cohort. The overall survival rate for the pNETs patients was 86% during a mean follow-up period of 8.0 ± 4.6 years. CONCLUSIONS: In our MEN-1 cohort, non-functioning pNETs were the most frequent type of pancreaticoduodenal tumor, and the tumor size correlated with the risks of metastasis and death. Increased awareness, early diagnosis, and a multidisciplinary approach may improve the associated morbidity and mortality in these patients.

BACKGROUND: Few studies describe the radiological and laboratory characteristics of patients with Crohn's disease (CD) with intra-abdominal fistulae. OBJECTIVES: We aimed to describe a cohort of CD patients with intra-abdominal fistulae and determine characteristics associated with complex fistulae. METHODS: Data were gathered from medical records and imaging studies of patients. Evaluation included type of fistula, number of fistulae, and radiological characteristics. RESULTS: A total of 205 fistulae in 132 patients were identified with an average patient age of 31 (±12) years. The average time from CD diagnosis to fistula development was 7 years. The most common type of fistula was entero-enteric (53%). Patients with an extra-intestinal fistula presented with an average of 1.96 fistulae, compared with an average of 1.28 fistulae for those with a fistula limited to the bowel (p =0.01). Except for the number of fistula no other significant differences were observed in radiological characteristics of patients who were diagnosed with a fistula at time of CD diagnosis compared to those diagnosed with a fistula later. CONCLUSIONS: The most common CD-associated intra-abdominal fistulae are entero-enteric and entero-colonic fistulae. An extra-intestinal fistula and diagnosis of a fistula subsequent to diagnosis of CD were associated with an increased number of fistulae per patient.

BACKGROUND: Inflammatory bowel diseases (IBD) is a heterogenous, lifelong disease, with an unpredictable and potentially progressive course, that may impose negative psychosocial impact on patients. While informed patients with chronic illness have improved adherence and outcomes, previous research showed that the majority of IBD patients receive insufficient information regarding their disease. The large heterogeneity of IBD and the wide range of information topics makes a one-size fits all knowledge resource overwhelming and cumbersome. We hypothesized that different patient profiles may have different and specific information needs, the identification of which will allow building personalized computer-based information resources in the future. AIM: To evaluate the scope of disease-related knowledge among IBD patients and determine whether different patient profiles drive unique information needs. METHODS: We conducted a nationwide survey addressing hospital-based IBD clinics. A Total of 571 patients completed a 28-item questionnaire, rating the amount of information received at time of diagnosis and the importance of information, as perceived by participants, for a newly diagnosed patient, and for the participants themselves, at current time. We performed an exploratory factor analysis of the crude responses aiming to create a number of representative knowledge domains (factors), and analyzed the responses of a set of 15 real-life patient profiles generated by the study team. RESULTS: Participants gave low ratings for the amount of information received at disease onset (averaging 0.9/5) and high ratings for importance, both for the newly diagnosed patients (mean 4.2/5) and for the participants themselves at current time (mean 3.5/5). Factor analysis grouped responses into six information-domains. The responses of selected profiles, compared with the rest of the participants, yielded significant associations (defined as a difference in rating of > 0.5 points with a P < 0.05). Patients with active disease showed a higher interest in work-disability, stress-coping, and therapy-complications. Patients newly diagnosed at age > 50, and patients with long-standing disease (> 10 years) showed less interest in work-disability. Patients in remission with mesalamine or no therapy showed less interest in all domains except for nutrition and long-term complications. CONCLUSION: We demonstrate unmet patient information needs. Analysis of various patient profiles revealed associations with specific information topics, paving the way for building patient-tailored information resources.

CONTEXT: Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is rapidly emerging as feasible therapy for patients with pancreatic neuroendocrine tumors (pNETs) in selected cases, as a result of its favorable safety profile. OBJECTIVE: To assess the feasibility, safety, and efficacy of EUS-RFA in a cohort of patients with functional and nonfunctional pNETs (NF-pNETs). DESIGN: Data on pNET patients treated with EUS-RFA between March 2017 and October 2018 at two tertiary centers was retrospectively analyzed. RESULTS: The cohort included 18 adults (eight women, 10 men), aged 60.4 ± 14.4 years (mean ± SD), seven insulinoma patients, and 11 patients with NF-pNETs. Twenty-seven lesions with a mean diameter of 14.3 ± 7.3 mm (range 4.5 to 30) were treated. Technical success defined as typical postablative changes on a surveillance imaging was achieved in 26 out of 27 lesions. Clinical response with normalization of glucose levels was observed in all (seven of seven) insulinoma cases within 24 hours of treatment. Overall, there were no major complications 48 hours postprocedure. No clinically significant recurrences were observed during mean follow-up of 8.7 ± 4.6 months (range 2 to 21 months). CONCLUSIONS: EUS-guided RFA of pNETs is a minimally invasive, safe, and technically feasible procedure for selected patients.

INTRODUCTION: Esophageal achalasia is a rare condition, characterised by progressive dysphagia due to innervation of the esophageal muscles and non-relaxation of the lower esophageal sphincter. The standard of care of surgical treatment is laparoscopic Heller myotomy. POEM-Peroral endoscopic myotomy is a new approach offering incision-less and selective myotomy. AIMS: This study aims to describe our experience and outcomes using this new surgical technique. METHODS: We performed a retrospective study using prospectively maintained data of all achalasia patients treated by POEM in our department. Data collected included patient demographics, gender, age, BMI, data related to the disease course in addition to data related to the surgery itself as well as both short and long term post-operative follow-up. RESULTS: Over the course of five years we performed 86 POEM operations, demonstrating a decrease in the Eckardt score from a mean of 8.87 to a mean of 0.7 in the immediate postoperative. Mean operative time was 86 minutes, with mean hospitalization time of 4 days. Intraoperative complications included 2 mucosal injuries while post-operative complications included 4 incomplete mucosal closures, 5 recurrent dysphagia and 5 patients with reflux requiring medical therapy. CONCLUSIONS: In the last decade, POEM procedure is being performed worldwide and has been performed in our department for the past five years. Our results show a success rate of 94.2% with minor complications. In our institution, as in many institutions globally, POEM is the preferred method for treating achalasia.

BACKGROUND AND AIMS: A majority of acutely ill Crohn's disease [CD] patients who present to Emergency Department [ED] will undergo an abdominal CT to rule out disease complications. We aimed to generate a simple non-invasive scoring model to predict the presence of an intra-abdominal abscess in CD patients in the ED. METHODS: We performed a retrospective case-control study at four Israeli hospitals from January 1, 2010 to May 30, 2018. Inclusion criteria included patients with an established diagnosis of CD that had cross-sectional abdominal imaging performed. A total of 322 patients were included, and 81 [25%] were diagnosed with an intra-abdominal abscess. RESULTS: In univariate analysis, ileo-colonic location (odds ratio [OR] 1.88, p = 0.0148), perianal CD [OR 7.01, p = 0.0004], fever [OR 1.88, p = 0.0247], neutrophil-to-lymphocyte ratio [OR 1.12, p < 0.0001], and C-reactive protein [OR 1.10, p < 0.0001] were significantly associated with abscess formation, whereas current use of corticosteroids was negatively associated with abscess formation [OR 0.46, 95% CI, 0.2-0.88, p = 0.0192]. We developed a diagnostic score that included five parameters that were significant on multivariate regression analysis, with assignment of weights for each variable according to the coefficient estimate. A low cut-off score of ≤7 was associated with a negative predictive value [NPV] of 93% for abscess formation, whereas a high cut-off score of >9 was associated with a positive predictive value of 65%. We validated this score with an independent cohort [area under the curve of 0.881 and NPV of 98.5%]. CONCLUSION: We recommend incorporating this score as an aid for stratifying acutely ill CD patients in the ED with low or high probability of the presence of an intra-abdominal abscess.

PURPOSE: Portal vein thrombosis (PVT) is a common condition in cirrhotic patients and mostly attributed to portal hypertension. The objective of our study was to examine the association of PVT with hepatocellular carcinoma (HCC) in cirrhotic patients. METHODS: A retrospective study was performed to identify cirrhotic patients with thrombosis of the portal system. Clinical and laboratory characteristics were collected and analyzed. RESULTS: Thirty-nine patients were identified. Twenty-four out of 39 patients with PVT did not develop HCC (group A) after follow-up time of 38.5 months from the diagnosis of PVT. Eight patients (20.5%) were diagnosed with HCC within two weeks following diagnosis of PVT (group B). Seven patients (17.9%) were diagnosed with tumor thrombus (group C) at time of PVT diagnosis. The average age was 53.5, 66.5, and 69 years for groups A, B, and C respectively. Most patients (75 and 87.5% for groups B and C respectively) diagnosed with PVT and HCC were males. The most common cause of cirrhosis in groups B and C was chronic hepatitis B virus infection (HBV) in 62.5% and 50% respectively. The most common clinical presentation of PVT in group A was abdominal pain in 55.5% compared to new/worsening ascites in 43% and 37.5% for groups B and C respectively. The platelet count in groups B and C was higher as compared to that in group A (126 and 125 vs. 107 thousand, P = NS). CONCLUSION: In 38.4% of cases, new diagnosis of PVT was associated with concomitant diagnosis of HCC. Identifiable risk factors were chronic HBV infection and higher platelet count.

BACKGROUND: Hydatid cyst is a zoonotic disease caused by Echinococcus genera. Surgery is needed in most cases. We aimed to describe our center's experience in the surgical management of hepatic hydated cysts (HHC). METHODS: Data was retrospectively collected for patients who underwent operative management for HHC between the years 1994-2014. RESULTS: Sixty-nine underwent surgical treatment for HHC. Group A included 34 treated with an unroofing procedure, group B included 24 patients who underwent hepatectomy and group C included 11 patients who underwent peri-cystectomy. The median ± (range) age for groups A, B and C were 39.5 (6.5-69), 40 (17-74) and 32 (20-62), respectively (P > 0.1). Post-operative complications occurred in 16, 11 and 5 patients in group A, B and C, respectively, as assessed by clavien-dindo classification (CDC). The average CDC was significantly higher in the hepatectomy group as compared to the unroofing group (2.3 vs.1.5, P = 0.04). Recurrence was significantly higher after the unroofing procedure as compared to the hepatectomy group (P = 0.05). CONCLUSION: Surgery remains the mainstay of treatment for HHC, once surgery is pursued, the results are satisfactory.

BACKGROUND AND AIMS: Colorectal cancer (CRC) is largely preventable with routine screening and surveillance colonoscopy; however, interval cancers arising from precancerous lesions missed by standard colonoscopy still occur. An increased adenoma detection rate (ADR) has been found to be inversely associated with interval cancers. The G-EYE device includes a reusable balloon integrated at the distal tip of a standard colonoscope, which flattens haustral folds, centralizes the colonoscope's optics, and reduces bowel slippage. The insufflated balloon also aims to enhance visualization of the colon during withdrawal, thereby increasing the ADR. METHODS: In this randomized, controlled, international, multicenter study (11 centers), patients (aged ≥50 years) referred to colonoscopy for screening, surveillance, or changes in bowel habits were randomized to undergo either balloon-assisted colonoscopy by using an insufflated balloon during withdrawal or standard high-definition colonoscopy. The primary endpoint was the ADR. RESULTS: One thousand patients were enrolled between May 2014 and September 2016 to undergo colonoscopy by experienced endoscopists; 803 were finally analyzed (standard colonoscopy n = 396; balloon-assisted colonoscopy n = 407). Baseline parameters were similar in both groups. Balloon-assisted colonoscopy provided a 48.0% ADR compared with 37.5% in the standard colonoscopy group (28% increase; P = .0027). Additionally, balloon-assisted colonoscopy provided for a significant increase in detection of advanced (P = .0033) flat adenomas (P < .0001) and sessile serrated adenomas/polyps (P = .0026). CONCLUSION: Balloon-assisted colonoscopy yielded a higher ADR and increased the detection of advanced, flat, and sessile serrated adenomas/polyps when compared with standard colonoscopy. Improved detection by the G-EYE device could impact the quality of CRC screening by reducing miss rates and consequently reducing interval cancer incidence.

Gastroparesis is a debilitating progressive disease that significantly impacts a patient's life with limited and challenging treatments available. Although the pathogenesis is multifactorial, pylorospasm is believed to have a major underlying role. Several therapeutic interventions directed to the pylorus have been developed over the last decade, including intra-pyloric injections of botulinum toxin, transpyloric stenting, and surgical pyloroplasty. All of these treatment options had limited and disappointing results. More recently, gastric peroral endoscopic myotomy (G-POEM) has been reported as a treatment for refractory gastroparesis. In this review article, we provide an overview on gastroparesis with a focus on the therapeutic interventions. In addition, we provide a literature summary and pool analysis of the clinical efficacy, scintigraphic efficacy, and safety profile of all studies that evaluated G-POEM in gastroparesis. Overall, seven studies have reported on the use of G-POEM in gastroparesis, and the pooled analysis of these studies showed a technical success of 100%, with clinical efficacy as assessed by the Gastroparesis Cardinal Symptoms Index of 81.5%, gastric emptying scintigraphy normalization in approximately 55.5% of the cases, perioperative complications in 7.6%, and intraoperative complications in 6.6%. This suggests that G-POEM is a new promising therapeutic intervention for the treatment of gastroparesis with durable effect and limited potential adverse events.

Hepatocellular carcinoma (HCC) is among the leading causes of cancer-related mortality. The principal treatment is surgical resection or liver transplantation, depending on whether the patient is a suitable transplant candidate. However, in most patients with HCC the diagnosis is often late, thereby excluding the patients from definitive surgical resection. Medical treatment includes sorafenib, which is the most commonly used systemic therapy; although, it has been shown to only minimally impact patient survival by several months. Chemotherapy and radiotherapy are generally ineffective. Due to the poor prognosis of patients with HCC, newer treatments are needed with several being in development, either in pre-clinical or clinical studies. In this review article, we provide an update on the current and future medical and surgical management of HCC.
