Sphincter-preserving surgery for low rectal cancer improved the quality of life while maintaining the oncologic outcomes. A retrospective, descriptive study was conducted with 45 patients who underwent sphincter-preserving surgery for low rectal cancer at the National Cancer Hospital and Hanoi Medical University Hospital between January 2016 and April 2020. The mean age was 55.6 years old. Male: female ratio = 0.7:1. Nearly all patients presented with hematochezia (95.6%). 75.6% of the tumors are located within 4-6 cm from the anal verge. The anastomotic leak rate was 4.4%. All patients had a normal postoperative urinary function. The sexual dysfunction rate was low (15.8%) and reversible. None had erectile or ejaculation dysfunction. 97.8% satisfied with sphincter function after one year. Tumors located > 4 cm and the anastomosis sites located > 2 cm from the anal verge were good prognostic factors for the recovery of sphincter function (p < 0.05). The Parks procedure had optimistic postoperative outcomes with a low complication rate, minimal sexual dysfunction, and good sphincter function in long-term follow-up.

Very Low Rectal Cancer

In this work we intend to validate the long-term oncologic outcomes for very low rectal cancer over the past 20 years and to determine whether laparoscopic procedures are useful options for very low rectal cancer. A total of 327 patients, who electively underwent laparoscopic rectal cancer surgery for a lesion within 5 cm from the anal verge, were enrolled in this study and their long-term outcomes were reviewed retrospectively. Of 327 patients, 70 patients underwent laparoscopic low anterior resection (LAR), 164 underwent laparoscopic abdominal transanal proctosigmoidocolectomy with coloanal anastomosis (LATA), and 93 underwent laparoscopic abdominoperineal resection (APR). The conversion rate was 1.22% (4/327). The overall postoperative morbidity rate was 26.30% (86/327). The 5-year disease free survival (DFS), 5-year overall survival (OS), and 3-year local recurrence (LR) were 64.3%, 79.7%, and 9.2%, respectively. The CRM involvement was a significant independent factor for DFS (p = 0.018) and OS (p = 0.042) in multivariate analysis. Laparoscopic APR showed poorer 5-year DFS (47.8%), 5-year OS (64.0%), and 3-year LR (17.6%) than laparoscopic LAR (74.1%, 86.4%, 1.9%) and laparoscopic LATA (69.2%, 83.6%, 9.2%). Laparoscopic procedures for very low rectal cancer including LAR, LATA, and APR could be good surgical options in selective patients with very low rectal cancer.

Abstract Background Conformal sphincter preservation operation (CSPO) is a new surgical procedure for very low rectal cancers (within 4–5 cm from the anal verge). CSPO preserves more of the dentate line and distal rectal wall and also avoids injuring nerves in the intersphincteric space, resulting in satisfactory anal function after resection. The aim of this study was to analyze the short-term surgical results and long-term oncological and functional outcomes of CSPO. Methods Consecutive patients with very low rectal cancer, who had CSPO between January 2011 and October 2018 at Changhai Hospital, Shanghai were included. Patient demographics, clinicopathological features, oncological outcomes and anal function were analyzed. Results A total of 102 patients (67 men) with a mean age of 56.9 ± 10.8 years were included. The median distance of the tumor from the anal verge was 3 (IQR, 3–4) cm. Thirty-five patients received neoadjuvant chemoradiation (nCRT). The median distal resection margin (DRM) was 0.5 (IQR, 0.3–0.8) cm. One patient had a positive DRM. All circumferential margins were negative. There was no perioperative mortality. The postoperative complication rate was 19.6%. The median duration of follow-up was 28 (IQR, 12–45.5) months. The local recurrence rate was 2% and distant metastasis rate was 10.8%. The 3-year overall survival and disease-free survival rates were 100% and 83.9%, respectively. The mean Wexner incontinence and low anterior resection syndrome scores 12 months after ileostomy reversal were 5.9 ± 4.3, and 29.2 ± 6.9, respectively. Conclusions For patients with very low rectal cancers, fecal continence can be preserved with CSPO without compromising oncological results.

Purpose: To analyse changes in performing sphincter-saving resection procedures for low rectal cancer in HCMC Oncology Hospital in the last 15 years (2004-2019). Patients and Methods: Medical records of 17 cases of low rectal carcinoma operated on from January through Juin, 2019 in Surgery Department No 2, HCMC Oncology Hospital were studied retrospectively. Data were compared to that of cases of low rectal carcinoma also operated on in HCMC Oncology Hospital from January, 2000 through December, 2004 (2004 group). Results: Compared with 2004 group, the sphincter-saving resection rate significantly increased (53% vs 4%, p<0.001); although there were higher proportions of men (77% vs 36%, p=0.003) and of early stage patients (29% stage I vs 4%, p<0.001). Sphincter-saving resection procedures were performed for 53% low rectal cancer patients (95% CI: 28-77%). All patients with tumors more than 3cm from the anal verge were operated on with sphincter-saving resection procedures. Conclusion: There was a significant increment of sphincter-saving resection for low rectal cancer in HCMC Oncology Hospital in the last 15 years (2004-2019). It was not different from worldwide trends.

Anal Preservation

AbstractThe evolution over the past 20 years of anal preservation in rectal cancer surgery has been truly remarkable. Intersphincteric resection (ISR) reported by Schiessel in 1994 in Australia has been shown to enable anal preservation even for cancers quite close to the anus. In Japan, ISR via the detachment of the anal canal between the internal and external sphincters and excision of the internal sphincter first began to be practiced in the latter half of 1990. A multicenter Phase II trial of ISR in Japan suggested that 70% of the cases had relatively good function with less than 10 points of Wexner score but around 10% had severe incontinence that would not be improved for long term. The primary end point of the clinical study, 3-year local recurrence rate, was 13.2% across the overall cohort (T1, 0%; T2, 6.9%; and T3, 21.6%). When ISR is performed on T1/T2 rectal cancers, sufficient circumferential resection margin can be obtained even without preoperative chemoradiotherapy, and local recurrence rate was acceptably low. Based on these evidences, ISR is a currently important, standard treatment option among anal-preserving surgeries for T1/T2 low-lying rectal cancers. In Japan, a feasibility study (LapRC trial) of laparoscopic ISR on Stage 0 and Stage 1 low rectal cancer showed excellent outcomes. A prospective Phase II clinical trial targeting low rectal cancers within 5 cm from the anal verge (ultimate trial) is being performed and awaiting the results in near future.

e14181 Background: To evaluate the results of extended intersphincteric resection of T3 rectal cancer situated below 4cm from the anal verge, comparing the results of simple intersphincteric resection of T2 rectal cancer after mid-course chemoradiotherapy. Methods: Between 2000 Between 2000 and 2006, 67 patients with rectal cancer below 4cm from anal verge, underwent abdomino-intersphincteric resection reconstructed by inversion proctoplasty with a colonic J-pouch and diverting ileostomy. All patients received a total irradiation dose of 30 Gy with conventional fractions for 3 weeks. Capecitabine was administered 1000mg/m2 twice a day on 21 days during radiotherapy, followed curative surgery in a week without resting period. After preoperative radio-chemotherapy, patients with overt T2 lesion were 27 cases (40.3%) and received intersphincteric resection (Group I: simple intersphincteric resection), and patients with borderline cases or T3 lesion were 40 cases (59.7%) and received intersphincteric resection with quadrant resection of upper external sphincter and primary repair of the external sphincter as inversion proctoplasty (Group II: extended intersphincteric resection). Results: The mean patients age was 61.2 years. The mean location of cancer was at 3.2cm from anal verge (2-4cm). Anastomotic leakage was confirmed in 11 patients (16.4%). There was no postoperative mortality. The grade I, II of continence by Kirwan classification was 81.5%, 80.0% in Group I and II. Under 3 times stool frequency per day was 51.9%, 62.5% in Group I and II. Two patients (3.0%) experienced locoregional recurrence of pelvic cavity. 5-year overall survival rate was 83.6%. Conclusions: Simple and extended intersphincteric resection is seemed to be a safe and functionally acceptable procedure. And, neoadjuvant mid-course chemoradiotherapy using oral capecitabine 2,000 mg/m2/day on 21 days during 2 Gy radiation of each 15 weekdays is seemed to be a tolerable and effective modality, in patients with very low rectal cancer.
