Current state of laparoscopic rectal cancer surgery in Australasia

Background: To establish the current surgical approach to rectal cancer in a group of colorectal surgeons in Australasia and the current opinion regarding laparoscopic rectal cancer surgery. Methods: An online survey was distributed to the Colorectal Surgical Society of Australia and New Zealand members. Results: 123/177 surgeons responded. During the last year, 94.3% had performed a laparoscopic colorectal case, 77.2% a laparoscopic rectal case and 65% a laparoscopic rectal cancer case. The most common approach to high anterior resection was pure laparoscopic (52.8%). Low anterior resections were most commonly performed with a laparoscopic component (25.2% pure laparoscopic, 33.3% hybrid). Most surgeons (>50%) performed ultra‐low anterior resections or abdomino‐perineal resections via an open technique. In addition, 64.2% intended to perform laparoscopic total mesorectal excision (TME) within 2 years. Most surgeons believe that the quality of laparoscopic TME and oncological outcomes are similar, and surgical access and short‐term outcomes are superior when compared to the open procedure. The major concerns were in performing a low rectal transection, controlling haemorrhage and resource utilization/cost. Conclusion: Laparoscopic rectal surgery is now widely practiced by Australasian colorectal surgeons and projected to increase in the near future. However, only 10% of surgeons are routinely performing total laparoscopic ultra‐low anterior resections which may have implications for the generalizability of clinical trials in laparoscopic TME and the ability to credential surgeons in this technically challenging field. Quality of TME and oncological outcomes were rated similar to the open operation. Areas of concern included low rectal transection, haemorrhage control and resource utilization/cost.     

The difficult rectal stump

During proctectomy for rectal cancer, section and closure of the rectal stump with TA55 before stapled low colorectal anastomosis could be very difficult, especially in obese patient. In this situation, others solutions includes use of TA30 or Roticulator, closure of rectal stump by suture, use of laparoscopic endoGIA. If no device can be used, manuel colo-anal anastomosis can be performed after rectal version, instead of stapled very low colorectal anastomosis.

Laparoscopic rectal resection with anal sphincter preservation for rectal cancer

Background Total mesorectal excision (TME) is the surgical gold standard treatment for middle and low third rectal carcinoma. Laparoscopy has gradually become accepted for the treatment of colorectal malignancy after a long period of questions regarding its safety. The purposes of this study were to examine prospectively our experience with laparoscopic TME and high rectal resections, to evaluate the surgical outcomes and oncologic adequacy, and to discuss the role of this procedure in the treatment of rectal cancer. Methods Between December 1992 and December 2004, all patients who underwent elective laparoscopic sphincter preserving rectal resection for rectal cancer were enrolled prospectively in this study. Data collection included preoperative, operative, postoperative and oncologic results with long-term follow-up. Results A total of 218 patients were operated on during the study period: 142 patients underwent laparoscopic TME and 76 patients underwent anterior resection. Of the TME patients, 122 patients were operated using the double-stapling technique, and 20 patients underwent colo-anal anastomosis with hand-sewn sutures. Mean operative time was 138 min (range, 107–205), and mean blood loss was 120 ml (range, 30–350). Conversion to open surgery occurred in 26 cases (12%). Mortality rate during the first 30 days was 1%. Anastomotic leaks were observed in 10.5% of the patients. Of these, 61.9% needed reoperation and diverting stoma, and the rest were treated conservatively. Three patients had postoperative bleeding requiring relaparoscopy. Other minor complications (infection and urinary retention) occurred in 9.1% of patients. Mean ambulation time and mean hospital stay were 1.6 days (range, 1–5) and 6.4 days (range, 3–28) , respectively. Patients were followed for a mean period of 57 months. No port site metastases were observed during follow-up. The recurrence rate was 6.8 %. Overall survival rate was 67% after 5 years and 53.5% after 10 years. Conclusion Laparoscopic anterior resection and TME with anal sphincter preservation for rectal cancer is feasible and safe. The short- and long-term outcomes reported in this series are comparable with those of conventional surgery.

Laparoscopic versus open total mesorectal excision with anal sphincter preservation for low rectal cancer

Background The Laparoscopic approach has been applied to colorectal surgery for many years; however, there are only a few reports on laparoscopic low and ultralow anterior resection with construction of coloanal anastomosis. This study compares open versus laparoscopic low and ultralow anterior resections, assesses the feasibility and efficacy of the laparoscopic approach of total mesorectal excision (TME) with anal sphincter preservation (ASP), and analyzes the short-term results of patients with low rectal cancer.Methods We analyzed our experience via a prospective, randomized control trail. From June 2001 to September 2002, 171 patients with low rectal cancer underwent TME with ASP, 82 by the laparoscopic procedure and 89 by the open technique. The lowest margin of tumors was below peritoneal reflection and 1.5–8 cm above the dentate line (1.5–4.9 cm in 104 cases and 5–8 cm in 67 cases). The grouping was randomized.Results Results of operation, postoperative recovery, and short-term oncological follow-up were compared between 82 laparoscopic procedures and 89 controls who underwent open surgery during the same period. In the laparoscopic group, 30 patients in whom low anterior resection was performed had the anastomosis below peritoneal reflection and more than 2 cm above the dentate line, 27 patients in whom ultralow anterior resection was performed had anastomotic height within 2 cm of the dentate line, and 25 patients in whom coloanal anastomosis was performed had the anastomosis at or below the dentate line. In the open group, the numbers were 35, 27, and 27, respectively. There was no statistical difference in operation time, administration of parenteral analgesics, start of food intake, and mortality rate between the two groups. However, blood loss was less, bowel function recovered earlier, and hospitalization time was shorter in the laparoscopic group.Conclusion Totally laparoscopic TME with ASP is feasible, and it is a minimally invasive technique with the benefits of much less blood loss during operation, earlier return of bowel function, and shorter hospitalization.
