Minimally invasive surgery with adenocarcinoma of jejunum diagnosed pathologically before surgery

Abstract Introduction and importance We report a rare case of a patient diagnosed with adenocarcinoma of the jejunum. Presentation of case The patient was a 58-year-old female patient who was tested for vomiting and dyspeptic symptoms at a local hospital and visited the hospital due to suspected small bowel obstruction. CT enteroscopy performed at our clinic revealed “progression of focal wall thickening in small bowel with proximal bowel dilatation”, and it was necessary to differentiate between malignant and infectious lesions. Balloon enteroscopy was planned for endoscopic observation up to the small bowel. The biopsy result was confirmed as adenocarcinoma with moderated differentiated. The patient underwent small bowel resection and anastomosis using standard laparoscopic surgery. Jejunum resection was performed by securing a safety margin of 10 cm or more, and sufficient LN dissection was also performed. The patient was discharged from the hospital without any specific complications, and as a result of pathology examination, it was confirmed
