Background and aims: Mammoplasty, a common cosmetic procedure involving breast augmentation and reduction surgeries, has gained global popularity. Recently, attention has shifted towards understanding the prevalence and significance of gastrointestinal (GI) symptoms following mammoplasty. This systematic review aims to consolidate existing literature to provide a comprehensive overview of the type and frequency of GI problems associated with various mammoplasty procedures.

Methods: A systematic search of PubMed and Scopus databases was conducted until January 22, 2024, identifying observational and interventional studies examining GI symptoms post-mammoplasty. Inclusion criteria covered human studies, while exclusion criteria ensured specificity. Two independent investigators performed screening, and data extraction included study characteristics, surgical procedures, anesthesia methods, and interventions.

Results: Nineteen studies, involving 2,487 subjects, were included in the review. Breast reconstruction emerged as the most studied procedure, followed by breast reduction, augmentation, mastectomy, and breast cancer surgery. Predominant GI symptoms included nausea and vomiting, with varying rates across mammoplasty types. Anesthesia modality influenced symptomatology, with general, local, and combined anesthesia associated with GI disturbances. Antiemetics, notably ondansetron and droperidol, showed variable efficacy. Non-pharmacological approaches, such as preoperative hypnosis, were explored for symptom management.

Conclusions: Our systematic review reveals insights into GI symptoms post-mammoplasty, emphasizing the common occurrence of symptoms such as nausea and vomiting, alongside less frequent manifestations such as constipation, dry mouth, retching, abdominal pain, and tightness. Variations in symptom prevalence were noted across diverse mammoplasty surgeries, anesthesia methods, and the use of antiemetics, underscoring the complex nature of post-mammoplasty GI disturbances.

Background and aims: Recent research has shown that Western-style diets have been associated with an increased risk of inflammatory bowel diseases (IBD). Our aim was to examine the link between an anti-inflammatory diet and the maintenance of IBD remission, as well as to assess the potential therapeutic advantages of this dietary approach in preserving IBD remission.

Methods: The inclusion and exclusion criteria were applied to a total of 189 individuals with IBD, with 21 individuals not meeting the criteria. Therefore, 168 eligible patients were enrolled in the study and allocated to either an anti-inflammatory diet or a regular diet, based on their personal preference.

Results: A cohort of 168 IBD adult patients was recruited for the study: 88 patients with ulcerative colitis and 80 with Crohn's disease. The intervention group received an anti-inflammatory diet consisting of the removal of red and processed meat, fried foods, high-lactose foods, fast food, white bread, sugar, and vegetable oils rich in omega-6 for a period of 1 year. The clinical response was maintained in 80 patients (95.2%) in the intervention group and in 72 patients (85.7%) in the control group (p-value=0.036). Although not statistically significant, fecal calprotectin was higher in the control group than in the intervention group at follow-up.

Conclusions: Patients who adhered to an anti-inflammatory diet exhibited a higher rate of maintenance of clinical remission. Furthermore, improvement in inflammation tests was observed in the intervention group, reinforcing the proposition that IBD is a lifestyle-related disease.

The "tumbling gallstone sign" is a diagnostic imaging finding described on radiologic examinations of the abdomen, in patients with cholelithiasis associated with intermittent episodes of gallstone obstructive ileus.  Best seen on serial radiographs or CT studies of the abdomen, this sign indicates a sudden change in position of the gallstone(s) within the intestinal lumen from the upper segments of the bowel to the lower segments of the bowel, causing transient mechanical bowel obstruction.  The tumbling gallstone sign has been likened to that of the classic childrens' tumbling tower balancing game.  On repeat CT scans, the dislodged gallstone(s) may be seen proceeding distally and impact in the ileum at a level lower than that seen on the previous CT scans, analogous to the tumbling gallstone sign.

Background and aims: The environmental factors, apart from gluten ingestion predisposing to coeliac disease are poorly known. Smoking is associated with many immune-mediated diseases, but research on coeliac disease is scarce. This study aims to investigate how smoking affects the clinical presentation, presence of comorbidities and response to gluten-free diet in coeliac disease.

Methods: Altogether 815 adults with coeliac disease participated in a nationwide cross-sectional study. Participants were interviewed and smoking habits (never, former, or current smoker), clinical presentation of coeliac disease and presence of comorbidities were elicited. Serology and severity of small bowel mucosal lesions at diagnosis were gathered from the participants' medical records and follow-up serology was measured. Gastrointestinal symptoms and psychological well-being were assessed using validated questionnaires.

Results: Current smokers were more often male and were diagnosed at younger ages than never or former smokers. There were no differences between the groups in clinical presentation, severity of symptoms or mucosal lesions at diagnosis or in dietary compliance and clinical, serological, and histological recovery. Musculoskeletal disorders, particularly osteoporosis and osteopenia, were more common in never smokers than in other groups (14.5% vs. 5.1% and 4.1%, p<0.001), and cardiovascular disorders were diagnosed more often in former smokers (36.2% vs. 23.5% and 21.9%, p=0.003).

Conclusions: Smoking does not seem to have an impact on the clinical presentation, severity of symptoms or mucosal damage in coeliac disease. Histological and clinical recovery as well as seroconversion on gluten-free diet are not affected by smoking status.

Background and aims: There has been a growing emphasis on dietary therapies for irritable bowel syndrome (IBS). Furthermore, there has been an evolving evidence base for the low fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) diet, gluten-free diet (GFD), and lactose-free diet. This study examines the dietary approaches employed and the factors influencing dietetic decision-making for IBS interventions.

Methods: Participants, including registered dietitians and nutritionists, were recruited from diverse healthcare settings at the point of registration for the 4th Sheffield National Dietetic Gastroenterology Symposium, 2023. A 15-question online survey investigated the practices of dietitians and nutritionists in managing IBS patients, covering dietary approaches, decision-making factors, and patient education. The evidence base for different dietary interventions was provided and a follow-up survey assessed symposium attendees, views on current IBS dietary practices.

Results: Out of 731 respondents, primarily registered dietitians (93%) and females (93%), 54% spent 10-50% of clinic time on IBS. Respondents noted that a GFD (34%), low lactose (32%), and traditional dietary advice (TDA) (18%) were the most frequently used dietary interventions that patients try before seeking professional advice. Delegates were asked to rank their dietary intervention preferences pre- and post-meeting (after the evidence base had been presented): TDA pre-meeting 75% versus post-meeting 87% (p=0.04), fibre modification 59% versus 6% (p<0.0001), low FODMAP 25% versus 10% (p=0.0001), low lactose 12% versus 62% (p<0.0001) and GFD 6% to 23% (p<0.0001).

Conclusions: TDA remains the choice of diet for dietitians. After our educational event, the use of low-lactose and gluten-free diet significantly increased. Factors influencing the decision-making process were based on patient acceptability, counselling time, supporting evidence base and dietary triggers.

Background and aims: Colonoscopy has a vital role in the diagnosis of inflammatory bowel disease (IBD), as well as in the estimation of disease severity, monitoring response to therapy, and surveillance for neoplasia. We performed a systematic review of randomised trials of various bowel preparations for colonoscopy in IBD.

Methods: We searched various electronic databases (PubMed, Embase, and CENTRAL) for studies reporting about the use of various strategies to improve colonoscopy preparation in IBD. We included only randomized clinical trials (RCTs). A network meta-analysis was done using a frequentist approach to compare the effectiveness of various bowel preparations. The risk of bias was assessed using Cochrane risk of bias tool 2.0. Other outcome parameters like compliance, tolerance, acceptance, and adverse effects were assessed qualitatively.

Results: Seven RCTs reporting about 960 patients were included. On comparison with 4 liter (L) of poliethylen glycol (PEG), oral sulfate solution (OR=1.1, 95%CI: 0.65-1.86); PEG2L/Ascorbate (OR=0.98, 95%CI: 0.65-1.48); PEG1L (OR=1, 95%CI: 0.55-1.81); PEG2L plus bisacodyl (OR=1.08, 95%CI: 0.71-1.65); PEG4L plus simethicone (OR=1, 95%CI: 0.67-1.50); PEG/ sodium picosulfate and magnesium citrate (SPMC) 1.5L (OR=0.99, 95%CI: 0.55-1.78); SPMC 2L (OR=1.09, 95%CI: 0.61-1.97) had similar effectiveness. Three RCTs reported compliance, five RCTs reported tolerance, two studies reported patient acceptance and five RCTs reported data on the willingness of patients to repeat the procedure in the future. Low-volume preparations had better compliance, tolerance, acceptance, and willingness to repeat. No difference in additional outcomes like change in disease activity after colonoscopy, procedure-related outcomes after colonoscopy like cecal intubation rate, and change in electrolyte levels were found.

Conclusion: Various bowel preparations had similar effectiveness in respect to colonoscopy preparation in IBD patients. Low-volume preparations have better compliance, tolerance, and acceptance. The systematic review was limited by a small number of included RCTs.

Background and aims: Progression to hepatocellular carcinoma (HCC) is restricted by viral suppression in chronic hepatitis B (CHB); however, some patients still progress despite antiviral therapy. Presence of single nucleotide polymorphisms (SNPs) such as PNPLA3 rs738409 and TM6SF2 rs58542926 are associated with the development and progression of steatotic liver disease to HCC, whereas a splice variant in HSD17B13 rs72613567:TA has been shown to be protective. We investigated the role of these SNPs in the development or prognosis of HCC in pure CHB etiology, in the absence of hepatic steatosis, remains unknown.

Materials: We analysed PNPLA3 rs738409, TM6SF2 rs58542926, and HSD17B13 rs72613567 SNPs in a prospectively recruited cohort (n=323) consisting of healthy controls, CHB and CHB-HCC patients without hepatic steatosis. SNPs were determined by PCR analysis and associations for the alleles and genotypes were investigated using adjusted-logistic regression analyses. The overall survival (OS) data were collected from CHB-HCC patients for survival analysis.

Results: The genotype and allelic distribution of PNPLA3 rs738409, TM6SF2 rs58542926, and HSD17B13 rs72613567 were similar between healthy controls, CHB, and CHB-HCC groups. No genotype, allele or haplotype analysis was found to be associated with increased risk for CHB-HCC. Survival analysis revealed no genotype or allele to be associated with OS in patients with CHB-HCC.

Conclusions: We could not demonstrate any association of PNPLA3 rs738409, TM6SF2 rs58542926, and HSD17B13 rs72613567 with the development or prognosis of CHB-HCC, supporting the initial hypothesis that they should be considered specific hotspots for liver diseases characterized with hepatic steatosis.
