Characterising oesophageal motility disorders by high-resolution impedance manometry in dermatomyositis patients.

OBJECTIVES: We studied high-resolution impedance manometry (HRiM) findings in dermatomyositis (DM) to detect oesophageal dysmotility, even in asymptomatic patients, and correlated the alterations to clinical and serological disease domains. METHODS: We performed a cross-sectional study of DM patients, enrolled between December 2021 and December 2022. All patients underwent rheumatological, laboratory and HRiM assessment. HRiM findings were compared with different clinical and serological profiles. RESULTS: The study population consisted of 15 DM patients (13 women and 2 men, age 54±15.2 years). The mean disease duration was 6.6 years. According to HRiM findings, three different groups of oesophageal disease severity were identified (in order of severity G0, G1 and G>1, 5 patients per group). G>1 group was significantly associated with MDA5 antibodies (80% vs. 20%, p<0.05). Interstitial lung disease (ILD) did not show any significant association with HRiM findings. However, a diffusing lung capacity for carbon oxide (DLCO) < 80% was present in 100% of G>1 (p<0.05). No associations between dysphagia, creatine kinase (CK) level, muscle weakness, skin, articular involvement and treatment were found. CONCLUSIONS: Oesophageal involvement is frequent and should be evaluated in the comprehensive work-up of DM. We used for the first time HRiM in DM, which proved to be an accurate and objective technique in assessing oesophageal disease, even in the subclinical stage. Interestingly, the MDA5-positive group had a higher burden of HRiM pathological findings, suggesting a greater severity of oesophageal involvement, often asymptomatic.

Surgical Management of Complicated Abdominal Tuberculosis: The First Systematic Review-New Treatments for an Ancient Disease and the State of the Art.

Background: Abdominal tuberculosis comprises all forms of tuberculosis that involve the gastrointestinal tract. Controversies exist regarding the surgical approach and timing and type of intervention for complicated forms of abdominal tuberculosis. The aim of this systematic review is to define the rate of surgical treatment, the type of surgical procedures performed and the role of minimally invasive surgery in the management of abdominal tuberculosis. Methods: The literature in MEDLINE, Scopus and Google Scholar and forward and backward citations for studies published between database inception and July 2022 were searched without language restrictions. All prospective and retrospective studies were included. The electronic database search yielded 2440 records. Additionally, eight records were identified through snowball searching. Following duplicate removal (45 duplicates found), 2403 records were screened for titles and abstracts. After screening for titles and abstracts and exclusion criteria, 38 reports were included for systematic review, 27 retrospective studies and 11 prospective studies. Data extracted included the general and demographic characteristics of the studies, diagnostic methods used, clinical presentation, site of involvement and details on surgical treatment. Results: In total, 2870 patients with a diagnosis of abdominal tuberculosis were included, and 1803 (63%) underwent a surgical procedure. The majority of patients underwent an open surgical procedure (95%). The most commonly performed procedures were adhesiolysis (21%) and small bowel resection with primary anastomosis (21%). Conclusions: The results of this review suggest that whenever surgery is required, there is a tendency to perform open surgical procedures in patients with complicated abdominal tuberculosis, both in emergency and elective settings, despite advances in minimally invasive surgery. The study protocol was registered on PROSPERO (CRD42022354322).

Tentacle Mesh for Fixation-Free Spigelian Hernia Repair: Mini-Invasive Approach Granting Broad Defect Overlap.

BACKGROUND: Compared to other types of abdominal protrusions, Spigelian hernias are not very common. In prosthetic repair of abdominal protrusions, mesh fixation and defect overlap are an open issue, as they are a source of complications. A newly developed tentacle-shaped mesh has been used to ensure a fixation-free repair with a broader defect overlap in the repair of abdominal hernias. This study describes the long-term results of a fixation-free repair of Spigelian hernias carried out with a tentacle mesh. METHODS: A proprietary mesh composed of a central body with integrated radiating arms was used for repairing Spigelian hernias in 54 patients. The implant was positioned in preperitoneal sublay, and the straps were delivered across the abdominal musculature with a needle passer, and then, after fascia closure, cut short in the subcutaneous layer. RESULTS: The friction of the straps passing through the abdominal wall served to hold the mesh in place, guaranteeing a wide overlap over the defect without fixation. In a long-term follow-up of 6 to 84 months (mean 64 months), a very low rate of complications occurred, but no recurrence was reported. CONCLUSIONS: The tentacle strap system of the prosthesis allowed for an easy, fast and safe fixation-free placement granting a wide overlap, avoiding intraoperative complications. Greatly reduced pain and a negligible amount of postoperative complications characterized the postoperative outcome.

Altered Gut Microbic Flora and Haemorrhoids: Could They Have a Possible Relationship?

To date, the exact pathophysiology of haemorrhoids is poorly understood. The different philosophies on haemorrhoids aetiology may lead to different approaches of treatment. A pathogenic theory involving a correlation between altered anal canal microflora, local inflammation, and muscular dyssynergia is proposed through an extensive review of the literature. Since the middle of the twentieth century, three main theories exist: (1) the varicose vein theory, (2) the vascular hyperplasia theory, and (3) the concept of a sliding anal lining. These phenomena determine changes in the connective tissue (linked to inflammation), including loss of organization, muscular hypertrophy, fragmentation of the anal subepithelial muscle and the elastin component, and vascular changes, including abnormal venous dilatation and vascular thrombosis. Recent studies have reported a possible involvement of gut microbiota in gut motility alteration. Furthermore, dysbiosis seems to represent the leading cause of bowel mucosa inflammation in any intestinal district. The alteration of the gut microbioma in the anorectal district could be responsible for haemorrhoids and other anorectal disorders. A deeper knowledge of the gut microbiota in anorectal disorders lays the basis for unveiling the roles of these various gut microbiota components in anorectal disorder pathogenesis and being conductive to instructing future therapeutics. The therapeutic strategy of antibiotics, prebiotics, probiotics, and fecal microbiota transplantation will benefit the effective application of precision microbiome manipulation in anorectal disorders.
