Background: Malignant bowel obstruction is a common cause of morbidity and mortality in patients with advanced ovarian cancer. Many patients aren't suitable for, or decline, surgical decompression. The outcomes for this frail group of patients are not well characterized.
Aim: To evaluate survival outcomes of ovarian cancer patients who undergo non-surgical management of malignant bowel obstruction.
Design: Systematic review and meta-analysis.
Data Sources: Online literature search of Pubmed, Embase and Medline libraries up until December 2020. Searching abstracts of scientific meetings, reference lists of included studies and contacting experts in the field.
Selection Criteria: Studies that investigated non-surgical management of confirmed bowel obstruction in advanced ovarian cancer patients were included. All levels of evidence including RCTs, cohort studies and case-series if they included greater than 5 patients.
Data Collection And Analysis: The studies were independently chosen by two reviewers who extracted and analyzed the data separately through OpenMeta Analyst software. Study quality was assessed using the JADAD score and the Newcastle Ottawa Score.
Results: 24 studies met the eligibility criteria for the systematic review and 9 for the meta-analysis. Median survival of patients managed non-surgically for bowel obstruction was 44 days (95% CI 38-49 days, I = 0%, P = 0.128).
Conclusion: The quality of studies was relatively low, however the evidence shows that non-surgical management of bowel obstruction results in a short life expectancy but with controlled symptoms. Where quality of life is the main concern, this may be a feasible and effective strategy.

Purpose: An initial analysis of population-based cancer survival data from Georgia revealed lower CRC survival rates compared to high-income countries. We conducted the study to address this issue and propose strategies for enhancing CRC care.
Patients And Methods: We analyzed CRC statistics, reviewed screening programs, and examined published CRC research in Georgia.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Intestinal fibrosis, as a late-stage complication of inflammatory bowel disease (IBD), leads to bowel obstruction and requires surgical intervention, significantly lowering the quality of life of affected patients. SAA3, a highly conserved member of the serum amyloid A (SAA) apolipoprotein family in mice, is synthesized primarily as an acute phase reactant in response to infection, inflammation and trauma. An increasing number of evidence suggests that SAA3 exerts a vital role in the fibrotic process, even though the underlying mechanisms are not yet fully comprehended.

While internal hernias are rare in the paediatric population, it should be considered as a cause for an acute abdomen following blunt trauma. Internal hernias represent a surgical emergency that requires prompt recognition due to the high risk of strangulation and ischaemia of affected bowel loops. The case of a transomental hernia (TOH) is described in a young girl.
