Comparison of short-term efficacy of transanal total mesorectal excision and laparoscopic total mesorectal excision in low rectal cancer

Background/objectiveThe transanal total mesorectal excision(TaTME) of rectal malignancies is largely referred to as treatment of mid to low, especially low rectal cancer. This study was to compare the short-term efficacy of TaTME and laparoscopic total mesorectal excision (LaTME) for low rectal cancer.MethodsA prospective study of patients with low rectal cancer who underwent laparoscopic radical surgery at the General Surgery of Guangzhou Red Cross Hospital from January 2017 to December 2019 was performed. The general information, perioperative results and pathological results of the two groups were compared.ResultsA total of 64 patients were included in the study, 32 in the TaTME group and 32 in the LaTME group. The clinical characteristics of the two groups was comparable (P > 0.05). The operation time in the TaTME group was longer than that in the LaTME group (212.59 ± 28.71min vs 187.66 ± 27.15min, P = 0.001), no significant differences were seen in the conversion rate, intraoperative complications, morbidity, serious morbidity, anastomotic leak, unplanned reoperation and hospital stay(P > 0.05). The circumferential resection margin (CRM) distance in the TaTME group was longer than that in the LaTME group (6.81 ± 2.99 mm vs 5.21 ± 3.06 mm, P = 0.039). The inter-group difference in terms of harvested lymph nodes, mesorectum integrity, CRM involvement, DRM distance, R1 resection, complete remission, pathological T stage, pathological N stage and pathological TNM stage was not significant (P > 0.05).ConclusionsTaTME is a promising surgical technique and maybe offers a safe and feasible alternative to LaTME in managing low rectal cancer.     

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.
