Gastro-intestinal mucormycosis (GIMM) is a highly lethal invasive fungal disease partly because of a challenging diagnosis. An allogeneic hematopoietic cell transplant recipient experienced bowel obstruction caused by slowly-evolutive gastro-intestinal mucormycosis and was successfully treated with surgery and antifungal therapy. Pathological findings revealed a granuloma without angio-invasion, which is unusual in this fungal disease and has incomplete similarities with an immune reconstitution inflammatory syndrome. Mucorales-specific PCR in both serum and resected tissue was positive and helped assessing the diagnosis. GIMM should be considered in front of unexplained granulomatosis or bowel obstruction in immunocompromised patients.

Background: The experience with Enhanced Recovery After Surgery (ERAS) protocols in neonatal intestinal surgery is very limited. We present the development and implementation of an Enhanced Recovery Protocol (ERP) designed specifically for neonates treated for congenital duodenal obstruction (CDO), and early outcome after implementation.

Methods: An ERP for CDO was developed and implemented.

An obturator hernia (OH) is a rare type of hernia that accounts for a very small proportion of all hernias and cases of small bowel obstruction. This condition predominantly affects older, underweight individuals, with the vast majority of patients being women. Laparotomy with simple suture closure of the defect is commonly used as surgical treatment for OH.

Trichobezoar or hairball in the proximal part of the gastrointestinal tract is a rare condition that occurs mainly in young and adolescent females. Since human hair is resistant to digestive enzymes and resistant to peristalsis, it easily accumulates between the folds of the mucosa. Over time, food and mucus accumulate within the hair, forming a compact mass that fills almost the entire lumen.

Introduction: Postoperative ileus (POI) is an inevitable complication after abdominal surgery, often hindering recovery and prolonging hospital stay. Despite the increasing use of electroacupuncture (EA) as an alternative treatment for gastrointestinal dysfunction, its effectiveness for POI is still controversial. This study aims to verify the efficacy and safety of EA in alleviating POI.

Introduction: Colonic fibrosis is a long-term complication of inflammatory bowel disease (IBD), often leading to functional impairment, intestinal obstruction, and surgery. Adiponectin (APN) is an adipokine derived from adipocytes that plays a pleiotropic role in fibrosis regulation, depending on tissue and cell type specific or disease context, but its role in colonic fibrosis remains unclear.

Objective: To explore the role and involved mechanism of APN in chronic colitis-associated colonic fibrosis.
