Status post sleeve gastrectomy and Roux-en-Y gastric bypass with antecolic anastomosis.
Small hiatal hernia.
Many signs are suggestive of Petersen hernia: mild fat stranding where the jejunum crosses the transverse colon; the jejunum immediately distal to the Treitz ligament is pulled to the right and slightly swirled; the mesenteric vessels are rotated (whirl sign) with mild mesenteric edema and slightly prominent lymph nodes; most of the small bowel is in the left abdomen and many bowel loops are located anterior to the distal transverse colon.
The abdominal organs (liver, spleen, pancreas, adrenals, and kidneys) are of normal dimensions and appearance.
Retroaortic left renal vein.
Small bilateral fat-containing inguinal hernia.
