Giant Paraesophageal Hernia With Obstructing Splenic Flexure Mass in the Left Hemithorax.

Giant paraesophageal hernias contain greater than fifty percent of the stomach above the diaphragm. Over fifty percent of large bowel obstructions are due to colorectal adenocarcinoma. Here, we present a rare case of a 69-year-old female patient who developed a closed loop colonic obstruction caused by a colonic mass in the distal transverse colon within a giant paraesophageal hernia. We successfully performed emergent paraesophageal hernia reduction and mesh repair with extended right hemicolectomy and ileocolonic anastomosis. Emergent hernia repair via an abdominal approach can be used in this setting.
