Single-incision laparoscopic colectomy: a novel approach through a Pfannenstiel incision.

BACKGROUND: Single-incision laparoscopic colectomy is evolving as a safe and feasible approach for the management of various diseases of the colon and rectum. The modality affords completion of "scarless" surgery through a transumbilical incision; however, this approach is associated with several limitations when performing colorectal procedures involving the pelvis. Collinear alignment of the camera and instruments through a single umbilical incision results in restricted visualization, inadequate dissection and mobilization, and the potential for inadvertent injury. We have developed an innovative approach utilizing a Pfannenstiel incision for single-incision access to the pelvis.
METHODS: Single-incision laparoscopic colon resection was performed using a single-access device placed through a mini-Pfannenstiel incision.
RESULTS: Three consecutive patients underwent single-incision laparoscopic anterior rectosigmoid resection for recurrent diverticulitis through a 4-cm Pfannenstiel incision. The procedures were performed at 150, 180, and 195 min with an estimated blood loss of 50, 150, and 75 mL, respectively. The resected specimen lengths were 10.5, 20.2, and 15.0 cm, respectively. There were no conversions to multi-port laparoscopic or open surgery. The length of hospital stay was 4 days for patients 1 and 2, and 3 days for patient 3. There were no major complications or readmissions during postoperative follow-up.
CONCLUSION: Single-incision laparoscopic anterior rectosigmoid resection for diverticulitis can be performed successfully through a Pfannenstiel incision. This approach facilitates direct visualization and access for rectal and pelvic dissection while maintaining adequate exposure to the left colon and splenic flexure during the procedure.
