Concurrent Appendicitis and Meckel's Diverticulitis Presenting With Small Bowel Obstruction in an Adult: A Case Report.

We present a case of multiple abdominal pathologies occurring simultaneously, which emphasizes the importance of keeping a broad differential and evaluating each diagnosis. A 33-year-old female presented with abdominal pain, nausea, and vomiting. Her workup included computerized tomography which demonstrated acute appendicitis with concern for a closed-loop bowel obstruction. She was offered diagnostic laparoscopy with anticipation of laparoscopic appendectomy and further evaluation for the source of the bowel obstruction. At the time of surgery, a Meckel's diverticulum with acute diverticulitis was identified, in addition to an inflamed appendix. A small band near the base of the Meckel's diverticulum was found and divided. The appendix was treated with a laparoscopic appendectomy and the Meckel's diverticulum was resected. She did well in recovery and continued to do well at her follow-up appointment. This case emphasized the importance of a thorough evaluation of a patient's differential diagnosis, as it is possible for multiple pathologies to occur simultaneously.
