RESUMO
BACKGROUND AND AIMS: Buried bumper syndrome (BBS) is a rare adverse event of percutaneous endoscopic gastrostomy (PEG) placement in which the internal bumper migrates through the stomal tract to become embedded within the gastric wall. Excessive tension between the internal and external bumpers, causing ischemic necrosis of the gastric wall, is believed to be the main etiologic factor. Several techniques for endoscopic management of BBS have been described using off-label devices. The Flamingo set is a novel, sphincterotome-like device specifically designed for BBS management. We aimed to evaluate the effectiveness of the Flamingo device in a large, homogeneous cohort of patients with BBS. METHODS: A guidewire was inserted through the external access of the PEG tube into the gastric lumen. The Flamingo device was then introduced into the stomach over the guidewire. This dedicated tool can be flexed by 180 degrees, exposing a sphincterotome-like cutting wire, which is used to incise the overgrown tissue until the PEG bumper is exposed. A retrospective, international, multicenter cohort study was conducted on 54 patients between December 2016 and February 2019. RESULTS: The buried bumper was successfully removed in 53 of 55 procedures (96.4%). The median time for the endoscopic removal of the buried bumper was 22 minutes (range, 5-60). Periprocedural endoscopic adverse events occurred in 7 procedures (12.7%) and were successfully managed endoscopically. A median follow-up of 150 days (range, 33-593) was performed in 29 patients (52.7%), during which no significant adverse events occurred. CONCLUSIONS: Through our experience, we found this dedicated novel device to be safe, quick, and effective for minimally invasive, endoscopic management of BBS.

BACKGROUND/AIMS: Traditionally, patients with acute diverticulitis undergo follow-up endoscopy to exclude colorectal cancer (CRC). However, its usefulness has been debated in this era of high-resolution computed tomography (CT) diagnosis. We assessed the frequency and outcome of endoscopic follow-up for patients with CT-proven acute diverticulitis, according to the confidence in the CT diagnosis. METHODS: Records of patients with CT-proven acute diverticulitis between October 2007 and March 2014 at Sandwell & West Birmingham Hospitals NHS Trust were retrieved. The National Cancer Registry confirmed the cases of CRC. Endoscopy quality indicators were compared between these patients and other patients undergoing the same endoscopic examination over the same period. RESULTS: We identified 235 patients with CT-proven acute diverticulitis, of which, 187 were managed conservatively. The CT report was confident of the diagnosis of acute diverticulitis in 75% cases. Five of the 235 patients were subsequently diagnosed with CRC (2.1%). Three cases of CRC were detected in the 187 patients managed conservatively (1.6%). Forty-eight percent of the conservatively managed patients underwent follow-up endoscopy; one case of CRC was identified. Endoscopies were often incomplete and caused more discomfort for patients with diverticulitis compared with controls. CONCLUSIONS: CRC was diagnosed in patients with CT-proven diverticulitis at a higher rate than in screened asymptomatic populations, necessitating follow-up. CT reports contained statements regarding diagnostic uncertainty in 25% cases, associated with an increased risk of CRC. Follow-up endoscopy in patients with CT-proven diverticulitis is associated with increased discomfort and high rates of incompletion. The use of other follow-up modalities should be considered.
RESUMO
OBJECTIVE: Barrett's oesophagus (BO) is associated with the development of oesophageal adenocarcinoma and endoscopic surveillance is commonly practised. In view of the clinical, psychological and economic implications of BO, we have studied patients' attitudes towards surveillance, their levels of anxiety and quality of life. METHODS: Patients with BO undergoing endoscopic surveillance were asked to complete a questionnaire,including seven questions on their experience of surveillance, the Hospital Anxiety and Depression Scale,the Trust in Physician Scale (TIPS) and the Short Form-36 quality of life questionnaire. RESULTS: Of the 250 patients invited, 178 responded (71%).One hundred and fifty-one (60%) completed the questionnaire sufficiently for analysis [median age 66 (range 41-79) years, 101 male]. Twenty-nine percent of patients had received too little information concerning surveillance of BO and 22% no information at all. Information was deemed difficult to understand by 24%. Hospital Anxiety and Depression Scale anxiety score: 14%abnormal, 25% borderline. Quality of life was lower than the general population in seven of eight Short Form-36 parameters. Increasing TIPS score correlated with having received (r= 0.33, P <0.001) and understood (r = 0.2, P= 0.037) BO information, and negatively with the belief that endoscopic surveillance reduced oesophageal adenocarcinoma risk (r= - 0.19, P =0.025). Increasing TIPS score was associated with less anxiety (P= 0.015) and depression (P =0.001), and better quality of life. CONCLUSION: Patients undergoing endoscopic surveillance for BO suffer anxiety and have impaired quality of life. As trust in their physicians is correlated with receiving sufficient BO information, we surmise that ensuring BO patients understand their condition is likely to improve quality of life, anxiety and depression.

BACKGROUND: Aggregation of symptoms of abdominal pain or bowel disturbance has been described in the families of patients with irritable bowel syndrome (IBS). This may be due to environmental factors, including learned responses to abdominal symptoms or a genetic contribution to the etiology of IBS. OBJECTIVES: To determine the relative contribution of genetic factors to IBS by evaluating IBS symptoms in monozygotic (MZ) and dizygotic (DZ) twins. METHODS: A total of 4,480 unselected twin pairs identified from a national volunteer twin register were asked to complete a validated questionnaire. IBS was defined by the Rome II criteria. RESULTS: A total of 5,032 subjects replied (56% response rate). One thousand eight hundred seventy complete twin pairs were evaluable; 888 MZ pairs (82 male pairs, mean age 51, SD 13 (range 19-81) yr) and 982 DZ pairs (69 male pairs, age 52, SD 13 (20-82) yr). The prevalence of IBS was 17% in MZ and 16% in DZ twins. There was no significant difference in casewise concordance rates between the MZ and DZ twins (28%vs 27%, p=NS). Logistic regression analysis revealed that decreasing age and increasing psychosomatic score were independently associated with IBS. Multifactorial liability threshold modeling suggested that a combination of unique and shared environmental factors provided the best model for IBS. In contrast, somatization was shown to be moderately heritable. CONCLUSION: Genetic factors are of little or no influence on IBS where the predominant influences appear to be environmental.

Barrett's esophagus (BE) is composed of multiple lineages including Paneth cells and endocrine cells in addition to gastric and intestinal cells. Although the origin of the BE stem cell is a matter of conjecture, the stem cells are clearly multipotent, and therefore the phenotype is restricted by genomic imprinting (termed restricted potency). Recent evidence suggests that the microenvironment may select various lineages. In this regard the proportion of gastric and specialized intestinal metaplastic cells has been attributed to the composition of the refluxate, acid or bile, respectively. Experimental evidence also implicates specific xenobiotics in this process, including bile acids. In particular we discuss the potential biologic roles of bile acids in epithelial adaptation from in vivo and in vitro models.
