Introduction: Gastrointestinal stromal tumors are the most common mesenchymal tumors of the gastrointestinal tract; however, gastrointestinal leiomyomas are relatively rare. Surgical resection is recommended for leiomyomas and gastrointestinal stromal tumors of the colon. We present a case in which we performed laparoscopic right hemicolectomy with intraabdominal anastomosis for treating leiomyoma of the transverse colon in a patient with an abdominal mesh.
Presentation Of Case: A 64-year-old woman with a history of right subtotal adrenalectomy and right mastectomy was incidentally found to have an abdominal mass on a follow-up computed tomography (CT) scan, which was confirmed as a gastrointestinal stromal tumor of the mesentery following abdominal contrast-enhanced CT. We planned surgical resection for preoperative diagnosis because the tumor was >5 cm in diameter. However, she had undergone transverse rectus abdominis myocutaneous (TRAM) flap reconstruction after right mastectomy, in which the TRAM flap was replaced with an abdominal mesh; hence, total laparoscopic surgery was performed to avoid damaging the mesh owing to the risk of mesh infection. Laparotomy revealed that the tumor originated from the transverse colon; thus, transverse colectomy with intraabdominal anastomosis was performed. The total operative time and blood loss were 3 h 32 min and 5 mL, respectively. No postoperative leakage or mesh infection was observed. The resected specimen revealed a leiomyoma without malignancy.
Discussion: We successfully performed colectomy that minimized the resection range and intraabdominal anastomosis.
Conclusion: Total laparoscopic surgery was effective for colonic leiomyoma with an abdominal mesh to avoid mesh-related complications.
