3 Procedure of Sigmoid Colectomy All small bowel loops are moved away from the pelvic cavity and the sigmoid colon and rectum are fully exposed. , from lateral to medial approach or the medial to lateral approach. Here the lateral-to-medial approach is described and it is the method developed from the early days of laparoscopic colectomy in Hong Kong and is more similar to the open approach and very good in the easy localization of the left ureter. By dividing the attachment of the sigmoid colon to the left pelvic brim and the lateral parietal peritoneum gradually from rectosigmoid junction up to the descending colon and dissecting the meso-sigmoid colon from its retroperitoneal attachment, the sigmoid colon and its mesentery can be freed up to the medial leave of meso-sigmoid colon and completely exposing the left ureter and left gonadal vessel.
Laparoscopic surgical operations that are difficult, expensive and come with high conversion rate. • With respect to difficult laparoscopic surgical operations, HALS provides a safe alternative to conversion, providing the same tactile feedback as open surgery. • Surgical operation that is too complex and technically demanding if performed by the traditional, laparoscopic method. 3 Contraindications 1. ) and patients with impaired cardiorespiratory function. 2. Absolute contraindications include patients with poor general health that cannot be optimised before surgery, and patients with cardiac, respiratory, hepatic or renal failure who are unable to sustain the proposed surgery.

It has in fact been instrumental in promoting the adoption of saparoscopic abdominal surgery. Preliminary data from studies conducted by the FDA (US) comparing HALS and standard laparoscopic surgery indicated that HALS colorectal resection is as safe as standard laparoscopic colorectal resection, has similar postoperative recovery, similar conversion rate but much less instrument and a shorter operating time.
