To report the complications and evaluate the risk factors of elective endoscopic cyanoacrylate injection with lauromacrogol for gastric varices in cirrhotic patients.

A total of 583 elective endoscopic tissue adhesives procedures were performed in 439 patients in our hospital from January 2015 to December 2016. The clinical characteristics and complications were retrospectively collected and evaluated.

The median age was 56 ± 11 years, and 290 (66.1%) patients were male. The main etiology of liver cirrhosis was hepatitis virus (63.3%). Two hundred fifty-nine (59.0%) patients were classified as Child-Pugh Class A. Bleeding occurred in 44 patients (7.5%) during procedures. Two patients developed distant embolism (0.5%; one pulmonary, one cerebra). In perioperative period, fever was a common complication; however, only 16 cases had high fever and one case had sepsis. Bleeding was observed in 7 (1.2%) patients. Overall incidence of the major perioperative complication was 3.8%. The major postoperative complations.

The aim of this study was to determine the nature of spontaneous regression of liver hemangiomas.

The records of the liver hemangioma patients who attended the out-patient clinic between 1988 and 2018 were evaluated. The data of the 716 adult patients who were followed for at least 3 years with cross-sectional imaging were analyzed.

Spontaneous regression was documented in 46 patients (6.4%). Twenty-eight patients had a single hemangioma (61%), eight (17%) had two hemangiomas; the other 10 patients had 3-6 hemangiomas. Of the 87 lesions in 46 patients, 69 actually regressed during the study. Twelve patients with more than one lesion exhibited discordant courses - one of the hemangiomas of a patient with multiple lesions regressed, whereas the other enlarged or remained stable. Eleven of the regressed hemangiomas exhibited enlargement first, followed by spontaneous regression. Fourteen (20%) of the regressed hemangiomas acquired atypical characteristics that would have suggested a malignancy had the original films been unavailable.

Spontaneous regression of liver hemangiomas is an underrecognized phenomenon. Enlargement should not be a straightforward indication for intervention because it may be followed by regression. A regressed hemangioma should be considered in the differential diagnosis of liver lesions suspicious for malignancy.

patients presenting with melena and nondiagnostic esophagogastroduodenoscopy are usually investigated with colonoscopy and if negative, with small bowel capsule endoscopy. In this pilot study, we tested feasibility and performance of panenteric capsule endoscopy (PCE) in patients presenting with melena and negative esophagogastroduodenoscopy.

Between January and December 2018, consecutive patients presenting with melena, clinically significant bleeding and negative esophagogastroduodenoscopy were invited to undergo PCE by swallowing PillCam Colon 2 (Medtronic Inc., Dublin, Ireland). PCE results, further diagnostic or therapeutic examinations, rebleeding rates at 30 days and 12 months were recorded.

Out of 128 patients with melena, 23 had negative esophagogastroduodenoscopy. Of them, 12 (8 female, mean age 76 years) underwent PCE, which allowed complete small bowel and colonic evaluation in 12 (100%) and 11 (91.7%) patients, respectively. The small bowel and colon cleansing were adequate in 100 and 83.3%scopy. Further large prospective randomized studies investigating this strategy are warranted.

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the main method for acquisition of tissue from gastrointestinal subepithelial lesions (SELs). Despite the development of new needles, diagnostic yield remains low. A new method of aspiration has been described, where the needle is filled with saline [wet-suction technique (WST)], with promising results in pancreatic lesions. This method has not been tested in SELs.

Prospective single center study to assess the diagnostic yield of EUS-FNA+WST in the diagnosis of SELs, without the use of rapid on-site evaluation. In mesenchymal tumors, the diagnosis was considered positive only when immunohistochemistry could differentiate between gastrointestinal stromal tumor and leiomyoma.

Eighty-seven patients with SELs were included (55% male, mean age 66 years). Mean SEL size was 25 mm (min 10 mm, max 120 mm), mean number of passes was 3 (±0.8). A 22G needle was used in 72 patients (83%), 19G in 10 (12%) and 25G in 5 (6%). We obtained a conclusive cytopathological diagnosis in 74 cases (diagnostic yield of 85%) and immunohistochemistry was performed in 70 cases (81%). The most frequent diagnoses were gastrointestinal stromal tumor (n = 34, 37%), leiomyoma (n = 13, 15%) and metastases (n = 10, 11%).

Wet suction technique allowed an excellent diagnostic yield in the EUS-guided evaluation of SELs. We suggest that, after proper replication of these results, WST may become the first-line method in the management of these lesions.

Thiopurines effectively maintain remission in ulcerative colitis patients. AG-1024 Whether early initiation of thiopurines after ulcerative colitis diagnosis decreases proximal disease progression and colectomy rates is not known.

We conducted a cohort study of ulcerative colitis subjects recruited from 1970 to 2009. Early thiopurine maintenance was defined as commencement of azathioprine or mercaptopurine within 5 years of diagnosis and maintenance for at least 6 months. Propensity score matching was conducted to correct for confounders influencing early thiopurine introduction. Outcomes of interest were colectomy rate and endoscopic proximal disease extension.

982 consecutive ulcerative colitis subjects (12 879 patient-years) were recruited with 116 requiring colectomy. Thiopurines initiation and maintenance increased over time with median time to thiopurine commencement decreasing from 23 years in the first decade to 2 years in the last decade (P < 0.0001). Multivariate analysis showed that early thiopurine maintenance significantly decreased the need for colectomy [hazard ratio, 0.
