Transanal versus laparoscopic total mesorectal excision for mid and low rectal cancer: a meta-analysis of short-term outcomes.
Conclusions: Transanal total mesorectal excision offers a safe and feasible alternative to LaTME although the clinicopathological features were not superior to LaTME in this study. Currently, with the lack of evidence on benefits of TaTME, further evaluation of TaTME requires large randomized control trials to be conducted. PMID: 31534564 [PubMed]
ConclusionsMRI pelvimetry can identify patients at risk for a poor-quality resection after laparoscopic proctectomy for mid- and low rectal cancer. These patients may benefit from the selective use of more advanced access methods to improve surgical resection quality.
ConclusionsMore extended resections seem not to confer an increase of the overall survival rate.
ConclusionThis meta-analysis based on nonrandomized studies suggests that TaTME seems better than LaTME in terms of overall and major morbidities, anastomotic leak, readmission rate, CRM involvement, and length of stay. These results need to be confirmed by randomized controlled trial.
AbstractBackgroundThe evidence regarding the impact of anastomotic leak (AL) after anterior resection (AR) for rectal cancer on oncologic outcomes is controversial, and there are no data about the prognostic relevance of the International Study Group of Rectal Cancer (ISREC) AL classification. The aim was to evaluate the oncologic outcomes in patients with AL after AR for rectal cancer. The prognostic value of the ISREC AL grading system was also investigated.MethodsIt is a retrospective analysis of a prospectively collected database including all patients undergoing curative elective AR for rectal cancer (April 1998 &ndas...
ConclusionMale sex and anterior wall tumor location were the risk factors for urinary dysfunction after laparoscopic rectal surgery.

ConclusionIndications for taTME at experienced centers have expanded to include complex reoperative cases, local recurrences, metastatic cancer, and tumors with threatened CRM or IAS with evidence of post-treatment tumor regression. In the latter cases, taTME achieves good short-term outcomes and may facilitate R0 resection.
ConclusionThe pathological outcomes between transanal and laparoscopic total mesorectal excision are similar. The rate of positive resection margin could not be significant decreased, nonetheless the decrease trend could be shown.
This study was designed to evaluate the impact of a standardized laparoscopic total mesorectal excision (TME) on the long-term oncologic outcome. Unselected consecutive patients with rectal cancer underwent a standardized laparoscopic TME with medial to lateral approach encompassing 9 sequential steps. From 2005 to June 2012, laparoscopic sphincter-preserving TME was attempted in 217 patients. Mean follow-up of all patients was a median of 91 months (range, 3 to 164 mo). The local recurrence rate was 6.5%, and the distant recurrence rate was 19.8%. The 10-year disease-free survival (DFS) rates were 76.4% and overall...
AbstractBackgroundGuidelines for rectal cancer treatment differ in Japan, Europe, and the United States. Neoadjuvant chemoradiotherapy (CRT) has been used to control lateral lymph nodes (LLNs) in the West. The usefulness of LLN dissection (LLND) has been discussed in Japan, and a randomized study stated the possible advantage of local control. However, it is still unclear whether adding LLND to CRT is beneficial.MethodsTo investigate the effectiveness of LLND on rectal cancer patients who underwent neoadjuvant CRT, we retrospectively collected magnetic resonance images (MRIs) in a cohort of 1500 patients with cStage II/III...
