Catastrophic outcome following misidentification of bowel anatomy during Hartmann's reversal: A case report and technical considerations.

Background: Reversal of Hartmann's procedure is a complex surgery with potential complications. This case report describes a rare and severe complication following an attempted reversal.

Case presentation: A 53-year-old male who had undergone a Hartmann's procedure for non-metastatic sigmoid colon cancer presented with bowel obstruction 10 days after attempted reversal surgery at another hospital. Imaging studies suggested an entero-colic fistula. Emergency laparotomy revealed dense adhesions and multiple bowel injuries. The procedure was terminated, and controlled fistulae were created.

Management and outcome: The patient required two months of intensive care. A subsequent surgery excised the fistulae and restored intestinal continuity, leaving the patient with an end colostomy and approximately 120 cm of ileum.

Conclusion: This case highlights the potential risks of Hartmann's reversal and emphasizes the importance of proper patient selection, timing, and surgical expertise. It underscores the need for thorough preoperative evaluation and preparation when attempting such complex surgeries.
