Diaphragmatic repair and/or reconstruction during upper abdominal urological laparoscopy.

Purpose: We present our experience with and the technique of laparoscopic mesh reconstruction or suture repair of intentional resection or intraoperative injury of the diaphragm.
Materials and Methods: In a 10-year (1997 to 2006) review of 1,850 upper abdominal renal and/or adrenal laparoscopic procedures at our institution 13 patients (0.7%) sustained diaphragmatic entry, including iatrogenic injury in 7 (0.4%), deliberate laparoscopic excision of a portion of the diaphragm in 2 and diaphragmatic incision during transthoracic adrenalectomy in 4. Laparoscopic repair techniques involved primary suture repair in 11 cases and primary reconstruction with a synthetic graft in 2. A rubber catheter and water seal system were used to primarily evacuate the pneumothorax.
Results: Inadvertent diaphragmatic injury in 7 cases occurred during transperitoneal (6) and retroperitoneal (1) laparoscopy, including partial nephrectomy in 4, radical nephrectomy in 2 and adrenalectomy in 1. A diaphragmatic breach occurred due to hook electrocautery in 5 cases, trocar insertion in 1 and liver retraction in 1. Deliberate diaphragmatic excision and mesh reconstruction in 2 cases were performed after en bloc excision of the diaphragm during radical nephrectomy in 1 and during excision of a metastatic diaphragmatic nodule in 1. Four transthoracic transdiaphragmatic adrenalectomies were completed successfully without any intraoperative complications. All cases were completed laparoscopically without open conversion. A chest tube was placed prophylactically in the initial 2 patients undergoing transthoracic transdiaphragmatic adrenalectomy.
Conclusions: Laparoscopic and transthoracic repair/reconstruction of the diaphragm is safe and effective.
