Background
The study aims to assess the functional outcome of anal sphincter sparing procedures (SSP) with TME for anorectal adenocarcinoma.
Methods
In a multicentric, prospective, single-group study in the period between December 2012 and November 2017, 93 patients presented with anorectal adenocarcinoma were included in the study. Sixty-nine patients underwent SSP with TME. SSP included the combined approach of transabdominal TME with intersphincteric resection (ISR) or transanal transabdominal TME (TATA). Using the Per Anal Examination Scoring System (PASS), postoperative anal function was assessed after one year.
Results
Bowel motility time was 50 (±19) hours. The time needed for narcotic analgesia was 54 (±18.8) hours. Mean hospital stay was 15.4 (±10.25) days. Incidence of evident fecal incontinence after ISR is 10.6% (7/67 cases). The Per Anal Examination Scoring System (PASS) findings of 69 cases are as follows: extremely hypotonic 8.6% (6 cases), slightly hypotonic 26.1% (18 cases), normal tone 58% (40 cases), slightly stenotic 3 cases (4.3%), or occluded 2.9% (2 cases). Urinary dysfunction occurred in one case (1.4%). Temporary diversion was performed in 61 patients (87.1%).
Conclusion
Sphincter preservation with TME for anorectal adenocarcinoma helps avoid permanent stoma and provides a reasonable functional outcome. PASS is a new application for postoperative assessment of anal function

Abstract PDF: The main goals in the surgical treatment of rectal cancer are to remove the cancer completely and to preserve the anorectal function. Rectal cancer is one of the leading health issues in Korea because of its increasing incidence with changing lifestyles and diets. The optimal treatment of rectal cancer is based on a multimodality approach. Among the modalities, proper surgery is the key for a curative treatment. In the early 20th century, local recurrence was reported to be as high as 30~40%. However, after the introduction of total mesorectal excision (TME), local recurrence decreased dramatically (to less than 10%). TME includes on sharp pelvic mesorectal dissection and complete clearing of the rectal cancer and the mesorectum along the rectal proper fascia. TME is now considered as a standard procedure for surgical treatment of rectal cancer. These days, sphincter-saving surgical techniques, such as transanal excision, ultralow anterior resection with coloanal anastomosis, and intersphincteric resection, have become popular for the treatment of low rectal cancer. Many researchers reported that oncologic outcomes were not compromised by the increased sphincter preservation rate. In clinical settings, the quality of life should be considered important because of the improved oncologic results in recent years. Surgeon should be aware of changes in the anorectal function after surgery. Reservoir and fecal continence, as well as sexual and voiding functions, should be closely evaluated during follow-up period. Impaired anorectal function may have multiple contributing factors: for example, a reduced reservoir volume, an unnoticed complex injury of the anal sphincter, or a traction injury (anal dilation). In terms of poor sexual and voiding functions, identification of the autonomic nerve plexus in the operative field is not enough for preserving the sexual and voiding functions. During pelvic dissection, traction injury caused by blunt dissection and electrothermal or vasa nervosum injury during sharp perimesorectal dissection should be avoided for better functional results. Preoperative or postoperative radiation may also be a reason for sexual and voiding dysfunction. If the ultimate goal of rectal cancer surgery is to be achieved, precise surgical technique and proper patient selection are mandatory. This issue contains recent advances in sphincter-saving surgery and nerve preservation for rectal cancer, which will be a useful reference for colorectal surgeons.

Abstract PDF

PURPOSE
Preoperative chemoradiation is the recommended standard therapy for locally advanced rectal cancer and is associated with sphincter preservation and improved survival. Our study was performed to determine the surgical outcomes and the prognostic factors for rectal cancer with preoperative chemoradiotherapy (PCRT) followed by a relative curative resection.
METHODS
We retrospectively reviewed the cases of 251 advanced rectal cancer patients who underwent a PCRT, between Jan 1995 and Dec 2002. All patients a received 25 days RTX (total dose: 4,500~5,040 cGy) and intravenous 5-FU (425 mg/m2/ day) plus leucovorin (20 mg/day) for 24 hrs. Surgery was performed about 4~6 weeks after completion of RTX. The median follow up was 79 months (range 1-142).
RESULTS
All patients were comfortable with PCRT. Postoperative mortality was 1.1%. After PCRT, 92.2% of the patients and, especially, 82.2% of the low rectal cancer patients had sphincter preserving surgery. Complete remission of the tumor was stenin 15.1% of the cases, but was not significantly associated with recurrence. The overall recurrence and the local recurrence rates were 15.1% and 4.4%, respectively. Cell differentiation, circumferential margin, and lymphovascular invasion were independent risk factors for local recurrence in the multivariate analysis. Prognostic factors for overall and disease-free survival were cell differentiation, circumferential margin, lymphovascular invasion, and lymph node metastasis in the multivariate analysis. The 5-year disease-free survival rates for stages I, II, and III, and for no-residual tumor were 96.1%, 83.4%, 69.0%, and 89.1%, respectively (P<0.05).
CONCLUSIONS
Advanced rectal cancer treated using preoperative chemoradiation resulted in excellent sphincter preservation. Our long-term follow-up results showed good local control and improved survival for rectal cancer.
