Introduction: Small bowel obstruction (SBO) is defined as a complete and persistent cessation of the transit of materials and gases. It occurs in a segment of the digestive tract located between the pylorus and the colorectal junction. Herein, we report a case of small bowel obstruction (SBO) following excessive consumption of wild grapes with no previous abdomen medical or surgical history. Presentation of case: A 65-year-old male farmer presented with cessation of materials and gas associated with vomiting of food and then bilious. The abdomen was bloated and painful on palpation with a moving, painful mass in the left iliac fossa. The hypothesis of acute occlusion of the colon was retained and confirmed on the X-Ray which showed a dilation of small bowel with air-fluid levels. The diagnostic of acute SBO was retained. We performed urgently a median laparotomy. We found the dilation of the loops from the jejunum to the sigmoid colon with a compact mass at the sigmoid colon of 15 cm in length and 6 cm in diameter. We proceeded to crush the mass that was made up with wild grape seed fecal, and push it back to the rectum. The phytobezoar made up with wild grape seeds was extracted through the anus with the fingers after anal dilation.
