Introduction: Early post-operative small bowel obstruction is challenging. After laparoscopic surgery, port site herniation and herniation through a peritoneal defect into the preperitoneal space should be considered as causes of early post-operative small bowel obstruction.
Case Report: A 36-year-old female developed early post-operative small bowel obstruction due to port-site Richter hernia after laparoscopic gastric bypass managed by diagnostic laparoscopy.
Conclusion: Early post-operative small bowel obstruction should always be suspected and diagnosed early in certain high risk procedures.
