Laparoscopic Sigmoid Colon Resection:Supine and Lateral
George Ferzli, MD, FACSProfessor of Surgery, SUNY Downstate Health Science Center, Brooklyn, NY
How is it done?
1. Lateral approach
2. Anterior approach
Patient with Large Ventral Hernia
Lateral Patient Position
• Patient positioned on right side
• Hand rotated in semicircle over sigmoid for trocar placement (more like triangle)
Trocar Placement: Lateral Position
Lateral PositionSplenic Flexture Mobilization
Lateral ApproachInferior Mesenteric Artery
Lateral Position
Lateral trocar cuts sigmoid
Repair - Lateral Position
If proximal colon can be brought through lateral incision tension-free, the repair will be tension free.
End to End Anastomosis
Lap. Sigmoidectomy - Lateral Position
Lateral Approach
Advantages• Easy mobilization of
splenic flexture
• Easier identification of ureter
• Small bowel out of the way in case of ventral hernia
Disadvantages• Inability to evaluate liver
• Poor access to adhesions or lesions on the right side of the recto-sigmoid
• In females, ovary may interfere
QuickTime™ and aVC Coding
Anterior Approach
• Patient supine
• Position hand over sigmoid and rotate in semi-circle to place trocars (3)
Trocar Placement: Anterior Position
Anterior Position
1
2
Trocar in inguinal crease cuts sigmoid
Repair – Anterior Position
If proximal colon can be brought through inguinal crease trocar incision, tension free repair will be successful.

Medial to Lateral LCR
From Jan 1999 to Dec 2004, 100 consecutive patients underwentthree trocar, M-L segmental laparoscopic colon resection.LCR’s included sigmoid (55%), right (34%), left (6%) andtransverse (5%). All conversions to open surgery (3%) occurred during the early learning curve.
Early LCR patients experienced greater morbidity (21% vs 12%)and mortality (5% vs 2%).
Significant and consistent improvement in the learning curve occurred after 38 LCR’s.
