Abstract
IMPORTANCE While oncological outcomes of early salvage total mesorectal excision (sTME) after local excision (LE) have been well studied, the impact of LE before TME on postoperative outcomes remains unclear. We aimed to compare early sTME with a primary TME for rectal cancer. METHODS Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines with the random-effects model were adopted using Review Manager Version 5.3 for pooled estimates. RESULTS We retrieved eleven relevant articles including 1728 patients (350 patients in the sTME group and 1438 patients in the TME group). There was no significant difference between the two groups in terms of mortality (OR = 0.90, 95%CI [0.21 to 3.77], p = 0.88), morbidity (OR = 1.19, 95%CI [0.59 to 2.38], p = 0.63), conversion to open surgery (OR = 1.34, 95%CI [0.61 to 2.94], p = 0.47), anastomotic leak (OR = 1.38, 95%CI [0.50 to 3.83], p = 0.53), hospital stay (MD = 0.23 day, 95%CI [- 1.63 to 2.10], p < 0.81), diverting stoma rate (OR = 0.69, 95%CI [0.44 to 1.09], p = 0.11), abdominoperineal resection rate (OR = 1.47, 95%CI [0.91 to 2.37], p = 0.11), local recurrence (OR = 0.94, 95%CI [0.44 to 2.04], p = 0.88), and distant recurrence (OR = 0.88, 95%CI [0.52 to 1.48], p = 0.62). sTME was associated with significantly longer operative time (MD = 25.62 min, 95%CI[11.92 to 39.32], p < 0.001) lower number of harvested lymph nodes (MD = - 2.25 lymph node, 95%CI [- 3.86 to - 0.65], p = 0.006), and higher proportion of incomplete TME (OR = 0.25, 95%CI [0.11 to 0.61], p = 0.002). CONCLUSIONS sTME is not associated with increased postoperative morbidity, mortality, or local recurrence. However, the operative times are longer and yield a poor specimen quality.

Abstract
Transanal excision (TAE) is considered a safe, alternative approach for patients with early stage of rectal cancer. Complications associated with TAE are rare, such as bleeding, perforation, incontinence, and rectal stricture. Subcutaneous emphysema is early complication of laparoscopic surgery, common during upper gastrointestinal and gynecological surgery. We report a case of retroperitoneal and subcutaneous emphysema emerging after TAE of rectal tumor. The patient presented with changed bowel habits. Colonoscopy with pathology reports, ultrasound, and magnetic resonance imaging showed an adenocarcinoma in the rectum at a 5 cm from the anus and did not reveal signs of invasive growth, pathologic lymph nodes, or systemic metastases. After surgery patient complained about abdominal pain and severe subcutaneous emphysema. Computed tomography showed retroperitoneal emphysema with no signs of rectal wall defect. He received antibiotics and was kept hospitalized with a solid diet and the retroperitoneal air disappeared on the thoracic X-ray. Patients who remain clinically stable or steadily improving without signs if peritonitis can be managed conservatively. Only in case of ineffectiveness of conservative therapy, undergo surgery.

Abstract
BACKGROUND Transanal excision (TAE) is increasingly used in the treatment of early rectal cancer because of lower rate of both postoperative complications and postsurgical functional disorders as compared with total mesorectal excision (TME) OBJECTIVE: To compare in a meta-analysis surgical outcomes and pathologic findings between patients who underwent TAE followed by completion proctectomy with TME (TAE group) for early rectal cancer with unfavorable histology or incomplete resection, and those who underwent primary TME (TME group). METHODS The Medline and Cochrane Trials Register databases were searched for studies comparing short-term outcomes between patients who underwent TAE followed by completion TME versus primary TME. Studies published until December 2016 were included. The meta-analysis was performed using Review Manager 5.0 (Cochrane Collaboration, Oxford, UK). RESULTS Meta-analysis showed that completion TME after TAE was significantly associated with increased reintervention rate (OR=4.28; 95% CI, 1.10-16.76; P≤0.04) and incomplete mesorectal excision rate (OR=5.74; 95% CI, 2.24-14.75; P≤0.0003), as compared with primary TME. However there both abdominoperineal amputation and circumferential margin invasion rates were comparable between TAE and TME groups. CONCLUSIONS This meta-analysis suggests that previous TAE impaired significantly surgical outcomes and pathologic findings of completion TME as compared with primary TME. First transanal approach during completion TME might be evaluated in order to decrease technical difficulties.

Abstract
The treatment for rectal cancer and benign rectal lesions continues to progress in the arena of minimally invasive surgery. While surgical excision of the primary mass remains essential for eradication of disease, there has been a paradigm shift towards less invasive resection methods. Local excision is increasing in popularity for its low morbidity and excellent functional results in select patients. Transanal minimally invasive surgery (TAMIS) is a new technology developed to elevate the practice of local excision to state-of-the-art resection. The goal of this article is to evaluate the history, short-term outcomes, and evolution of the TAMIS technique for excision of benign and malignant rectal neoplasia.

Abstract
BACKGROUND Laparoscopic surgery for rectal TME achieves better patient recovery, lower morbidity, and shorter hospital stay than open surgery. However, in laparoscopic rectal surgery, the overall conversion rate is nearly 20%. Transanal TME combined with laparoscopy, known as Hybrid NOTES, is a less invasive procedure that provides adequate solutions to some of the limitations of rectal laparoscopy. Transanal TME via TEO with technical variants (intracorporeal resection and anastomosis, TEO review of the anastomosis) attempts to standardize and simplify the procedure. METHOD Prospective observational study was used describe and assess the technique in terms of conversion to open surgery, overall morbidity, surgical site infection and hospital stay. The sample comprised consecutive patients diagnosed with rectal tumor less than 10 cm from the anal verge who were candidates for low anterior resection using TME (except T4). Demographic, surgical, postoperative, and pathological variables were analyzed, as well as morbidity rates. RESULTS From September 2012 to August 2014, 32 patients were included. The conversion rate was 0%. Overall morbidity was 31.3%, SSI rate was 9.4%, and mean hospital stay was 8 days. Oncological radical criteria were achieved with pathological parameters of 94% of complete TME and a median circumferential margin of 13 mm. CONCLUSION The introduction of technical variants of TEO for transanal resection can facilitate a procedure that requires extensive experience in transanal and laparoscopic surgery. Studies of sphincter function, quality of life, and long-term oncological outcome are now necessary.

Abstract
The optimal treatment of early (T1 and T2) rectal adenocarcinomas remains controversial. Local excision and radical resection with total mesorectal excision are the two surgical techniques for excising early rectal cancer. Each has their respective benefits, with local excision allowing for decreased operative morbidity and mortality while radical resection provides an oncologically complete treatment through lymphadenectomy. Local excision can be accomplished via transanal endoscopic microsurgery or transanal excision. There is no significant difference in the recurrence rates (21% vs. 33%) or overall survival (80% vs. 66%) between the two local excision modalities; however, transanal endoscopic microsurgery does allow for a higher rate of R0 resection. Current selection criteria for local excision include well to moderately differentiated tumors without high-risk features such as lymphovascular invasion, perineural invasion, or mucinous components. In addition, tumors should ideally be <3 cm in size, excised with a clear margin, occupy less than 1/3 of the circumference of the bowel and be mobile/nonfixed. Despite these stringent inclusion criteria, local excision continues to be plagued with a high recurrence rate in both T1 and T2 tumors due to a significant rate of occult locoregional metastases (20% to 33%). For both tumor groups, the recurrence rate in the local excision group is more than double compared to radical resection. However, the overall survival is not significantly different between those with and without metastases. With intense postoperative surveillance, these recurrences can be identified early while they are confined to the pelvis allowing for salvage surgical options. Recently, neoadjuvant therapy followed by local excision has shown favorable short and long-term oncological outcomes to radical resection in the treatment of T2 rectal cancer. Ultimately, the management of early rectal cancer must be individualized to each patient's expectations of quality and quantity of life. With informed consent, patients may be willing to accept a higher failure rate and an increased post-operative surveillance regimen to preserve a perceived increased quality of life.

Abstract
AIM: To compare the outcomes of endoscopic resection with transanal excision in patients with early rectal cancer.
METHODS: Thirty-two patients with early rectal cancer were treated by transanal excision or endoscopic resection between May 1999 and December 2007. The patients were regularly re-examined by means of colonoscopy and abdominal computed tomography after resection of the early rectal cancer. Complications, length of hospital-stay, disease recurrence and follow up outcomes were assessed.
RESULTS: Sixteen patients were treated by endoscopic resection and 16 patients were treated by transanal excision. No significant differences were present in the baseline characteristics. The rate of complete resection in the endoscopic resection group was 93.8%, compared to 87.5% in the transanal excision group (P = 0.544). The mean length of hospital-stay in the endoscopic resection group was 2.7 ± 1.1 d, compared to 8.9 ± 2.7 d in the transanal excision group (P = 0.001). The median follow up was 15.0 mo (range 6-99). During the follow up period, there was no case of recurrent disease in either group.
CONCLUSION: Endoscopic resection was a safe and effective method for the treatment of early rectal cancers and its outcomes were comparable to those of transanal excision procedures.
