Abdominoinguinal incision in adenocarcinoma of the sigmoid or cecum: report of two cases.

PURPOSE

This study illustrates a technique allowing resection of a sigmoid adenocarcinoma with lateral fixation and a cecal adenocarcinoma with involvement of the psoas muscle and ureter.

METHODS

The abdominoinguinal incision, an incision used in the resection of a sarcoma of the lower abdominal quadrants, was applied in the case of a sigmoid adenocarcinoma with posterolateral fixation and infiltration of the anterior abdominal wall and in a case of a cecal adenocarcinoma involving the right psoas muscle and ureter.

RESULTS

In the first case, resection of the tumor mass en bloc with resection of the sigmoid and lower anterior abdominal wall muscles, including the inguinal ligament, was performed. Reconstruction of the muscular fascial defect was done with the rotation of a right rectus abdominis flap. The patient was well 12 months later. In the second case, the cecal carcinoma was resected en bloc with the right psoas and ureter; a right nephrectomy was also performed. This patient was well eight months later.

CONCLUSIONS

The abdominoinguinal incision may provide the exposure needed to allow the resection of a sigmoid or a cecal adenocarcinoma with posterolateral fixation, often considered unresectable with conventional abdominal incisions.
