Pediatric mesenteric panniculitis is an extremely rare disease of unknown etiology characterized by chronic inflammation, fat necrosis, and fibrosis in the mesenteric adipose tissue. A previously healthy 13-year-old boy was admitted because of right upper abdominal pain. An abdominal computed tomography scan revealed increased attenuation and enhancement in the left upper abdominal omental fat ...

BACKGROUND AND STUDY AIMS Direct percutaneous endoscopic necrosectomy has been described as a minimally invasive intervention for the debridement of walled-off pancreatic necrosis (WOPN). In this retrospective cohort study, we aimed to confirm these findings in a US referral center and evaluate the clinical value of this modality in the treatment of pancreatic necrosis as well as other types of...

BACKGROUND Most morbidity and mortality are caused by a pancreatic fistula after pancreaticoduodenectomy (PD), and its prevention is the major concern. We applied the omental roll-up technique around pancreaticojejunostomy and investigated the effectiveness of this technique to prevent a pancreatic fistula. DESIGN Retrospective study. SETTING Tertiary hepatobiliary and pancreas surgery clin...

Because of its dynamic structure, the omentum plays a key role in the immunity of the peritoneal cavity by orchestrating peritoneal cell recruitment. Because mast cells accumulate in the omentum upon experimental peritoneal dialysis (PD) and may produce angiogenic/profibrotic factors, it was hypothesized that mast cells mediate omental tissue remodeling during PD. Daily treatment with conventio...

PURPOSE Adipose tissue products may contribute to endometrial cancer (EC) initiation and further growth that encourages the analysis of this issue in patients with different obesity phenotypes. METHODS/PATIENTS Omental fat depot characteristics were studied in EC patients (n = 57) with "standard" (SO) or "metabolically healthy" (MHO) obesity. Collected omental samples were evaluated by immuno...

Tumor necrosis factor alpha (TNFalpha) and leptin concentrations were determined in the abdominal subcutaneous and visceral (omental) adipose tissue of patients undergoing elective open-abdominal surgery and compared with their body mass index. The concentration of leptin did not differ significantly between women and men, being high in subcutaneous fat tissue and low in visceral fat tissue. TN...

Omental torsion is a rare cause of acute abdominal pain, and clinically mimics acute appendicitis. A 11-year-old boy presented with symptoms and signs suggestive of appendicitis. A computed tomography of abdomen revealed findings suggestive of omental torsion. Diagnostic laparoscopy confirmed the diagnosis of torsion of a segment of the greater omentum.

Hepatoid variant of yolk sac tumor of ovary is an unusual tumor with an aggressive behavior. It is usually observed in young females, presents with abdominal complaints and is associated with raised α-fetoprotein (AFP) levels. It should be differentiated from other hepatoid tumors involving the ovary. A complete patient evaluation with gross, microscopy, and immunohistochemistry can identify th...

Failed vesicovaginal fistula repairs are often considered complicated and are thus relegated to an abdominal approach using an interposition omental flap. We report our successful laparoscopic approach without use of an omental flap in a patient with multiple recurrences of a vesicovaginal fistula.
