<b>A Case Series Report: Gastrointestinal Disease Patterns and Management Challenges in the Gaza Strip During Humanitarian Crisis (2022-2024)</b>

The Gaza Strip has experienced unprecedented humanitarian crises during 2022-2024, characterized by severe infrastructure collapse, healthcare system fragmentation, and population displacement. This expanded case series examines the clinical presentations, management challenges, and outcomes of gastrointestinal diseases across twelve representative cases, with particular focus on the alarming development of multidrug resistance patterns. Our analysis includes infectious diarrheal diseases, inflammatory bowel disease exacerbations, peptic ulcer complications, nutrition-related disorders, and complex multi-system presentations, supplemented by robust epidemiological data. The cases demonstrate how resource constraints, limited diagnostic capabilities, and disrupted treatment protocols have accelerated antimicrobial resistance. Surveillance data reveals a 320% increase in acute watery diarrhea cases with multidrug-resistant organisms identified in 65% of cultured specimens. This comprehensive report highlights the urgent need for targeted interventions, improved medical supply chains, antimicrobial stewardship, and specialized training for healthcare workers managing complex GIT conditions in humanitarian emergencies.
