1. Severe Chronic Anemia and Tumor-Mimicking Colonic Lesions as an Atypical Presentation of Crohn’s Colitis
Authors: Ali Ghanem Al Masad, Mahdi Abdulhadi Al Muammar, Omar Reda Abdelmaksoud.
Journal: ACG Case Reports Journal. 2026;13(8).
DOI: 10.14309/crj.0000000000002258
Clinical highlights
This case describes an unusual presentation of Crohn’s colitis with profound transfusion-dependent anemia, recurrent hematochezia, and tumor-mimicking colonic lesions.
It emphasizes the importance of clinicopathologic correlation and careful exclusion of infectious and neoplastic mimics in complex inflammatory bowel disease presentations.

2. Stent-Assisted Percutaneous Direct Endoscopic Necrosectomy in Necrotizing Pancreatitis With Multidrug-Resistant Infection and Portal Vein Thrombosis
Authors: Ali Ghanem Al Masad, Samah Mosaad Soliman, Mana Saleh Al Qirad, Omar Reda Abdelmaksoud.
Journal: ACG Case Reports Journal. 2026;13(5).
DOI: 10.14309/crj.0000000000002118
Clinical highlights
This case describes the management of complex infected pancreatic necrosis associated with multidrug-resistant infection and portal and superior mesenteric vein thrombosis.
Stent-assisted percutaneous direct endoscopic necrosectomy enabled staged debridement and source control, followed by clinical recovery and portal vein recanalization.

3. Recurrent Anastomotic Leak After Hartmann Reversal: Successful Management With Vacuum-Assisted Endoscopic Drainage and Diversion
Authors: Ali Ghanem Al Masad, Omar Reda Abdelmaksoud.
Journal: ACG Case Reports Journal. 2026;13(2).
DOI: 10.14309/crj.0000000000001976
Clinical highlights
This case reports successful management of recurrent colorectal anastomotic leakage following Hartmann reversal using endoscopic vacuum-assisted therapy combined with surgical diversion.
The report illustrates a minimally invasive salvage approach that achieved healing and preserved bowel continuity without permanent diversion.
