Abstract
BACKGROUND Transanal endoscopic intersphincteric resection (ISR) surgery currently lacks sufficient clinical research and reporting. AIM To investigate the clinical effectiveness of transanal endoscopic ISR, in order to promote the clinical application and development of this technique. METHODS This study utilized a retrospective case series design. Clinical and pathological data of patients with lower rectal cancer who underwent transanal endoscopic ISR at the First Affiliated Hospital of Xiamen University between May 2018 and May 2023 were included. All patients underwent transanal endoscopic ISR as the surgical approach. We conducted this study to determine the perioperative recovery status, postoperative complications, and pathological specimen characteristics of this group of patients. RESULTS This study included 45 eligible patients, with no perioperative mortalities. The overall incidence of early complications was 22.22%, with a rate of 4.44% for Clavien-Dindo grade ≥ III events. Two patients (4.4%) developed anastomotic leakage after surgery, including one case of grade A and one case of grade B. Postoperative pathological examination confirmed negative circumferential resection margins and distal resection margins in all patients. The mean distance between the tumor lower margin and distal resection margin was found to be 2.30 ± 0.62 cm. The transanal endoscopic ISR procedure consistently yielded high quality pathological specimens. CONCLUSION Transanal endoscopic ISR is safe, feasible, and provides a clear anatomical view. It is associated with a low incidence of postoperative complications and favorable pathological outcomes, making it worth further research and application.

Abstract
PURPOSE Conformal sphincter preservation operation (CSPO) is a sphincter preservation operation for very low rectal cancers. Compared to intersphincteric resection (ISR), CSPO retains more dentate line and distal rectal wall, and also avoids damaging the nerves in the intersphincteric space. This study aimed to compare the postoperative anal function and quality of life between the CSPO and ISR. METHOD Patients with low rectal cancer undergoing CSPO (n = 117) and ISR (n = 66) were included from Changhai and Huashan Hospital, respectively, between 2011 and 2020. A visual analog scale (range 0-10) was utilized to evaluate satisfaction with anal function and quality of life. The anal function was evaluated with Wexner scores and low anterior resection syndrome (LARS) score. Quality of life was evaluated with the EORTC QLQ-C30 and QLQ-CR38. RESULTS The CSPO group had more male patients (65.8% vs. 50%, p = 0.042), more preoperative chemoradiotherapy (33.3% vs. 10.6%, p < 0.001), lower tumor position (3.45 ± 1.13 vs. 4.24 ± 0.86 cm, p < 0.001), and more postoperative chemotherapy (65% vs. 13.6%, p < 0.001) compared to the ISR group. In addition, CSPO patients had shorter postoperative stay (6.63 ± 2.53 vs. 7.85 ± 4.73 days, p = 0.003) and comparable stoma reversal rates within 1 year after surgery (92.16% vs. 96.97%, p = 0.318). Multivariable analysis showed that CSPO significantly contributed to higher satisfaction with anal function (beta = 1.752, 95% CI 0.776-2.728) and with quality of life (beta = 1.219, 95% CI 0.374-2.064), but not to Wexner, LARS score, or EORTC QLQ-C30 and QLQ-CR38. CONCLUSION CSPO improved the satisfaction with anal function and quality of life but utilized more preoperative chemoradiotherapy. CSPO may be an alternative choice for patients with very low rectal cancers in better physical health and with higher requirements for anal function and quality of life.

Abstract
OBJECTIVES This study aimed to compare the efficacy of local excision (LE) and intersphincteric resection (ISR) in patients with locally advanced rectal cancer who achieved a significant or complete pathological response following neoadjuvant chemoradiotherapy. METHODS We performed a retrospective analysis of data from patients with stage ypT0-1ycN0 low rectal cancer after neoadjuvant chemoradiotherapy who underwent LE or ISR between June 2016 and June 2021. Baseline characteristics, short-term outcomes, long-term oncological outcomes, and functional outcomes, were compared between the two groups. To reduce the selection bias, inverse probability of treatment weighting (IPTW) was performed. RESULTS This study included 106 patients (LE group: n = 51, ISR group: n = 55). There were significant differences in baseline characteristics between the two groups (P < 0.05). After IPTW, there were almost no significant differences in baseline data between the two groups. The LE group showed less postoperative complications and better function outcomes compared to the ISR group. The LE group had significantly lower rates of complications (13.7% vs. 36.4%, P = 0.014). There were no significant differences between the two groups in terms of long-term oncological outcomes. CONCLUSIONS For patients with locally advanced low rectal cancer achieving significant or complete pathological response after neoadjuvant therapy, both LE and ISR present comparable oncological outcomes. Yet, LE seems to show more advantages in terms of postoperative complications and functional outcomes. These findings offer important insights for surgical decision-making, emphasizing the necessity to consider both oncological and functional outcomes in selecting the optimal surgical approach.

Abstract
PURPOSE Our aim was to perform a propensity score-matched study to compare the long-term functional outcomes and quality of life following intersphincteric resection vs. low anterior resection (LAR) with very low anastomosis. METHODS Patients who underwent intersphincteric resection or low anterior resection with low anastomosis (≤ 4 cm from the anal verge) for rectal cancer between January 2017 and June 2020 were retrospectively included. A propensity score-matching process was performed. Functional outcomes and quality of life were assessed using the European Quality of Life 5 Dimensions 3 Level Version (EQ-5D-3L), EORC-QLQ C30, EORC-QLQ CR29, Low Anterior Resection Syndrome (LARS), Wexner, and International Prostate Symptom Score (IPSS) questionnaires. The primary outcome was the presence of LARS at least 12 months after surgery. The second outcome was the postoperative quality of life of included patients. RESULTS After propensity matching, 128 patients were included, including 58 males and 70 females with a median age of 59.5. Patients in the intersphincteric resection group showed a higher incidence of incontinence to flatus (32.8% versus 14.0%, p = 0.043) and stools (42.2% versus 21.9%, p = 0.046), pain/discomfort (25.0% versus 7.8%, p = 0.001), and bowel dysfunction, while the LARS scores (15.0 versus 13.2, p = 0.461) and major LARS rates (26.6% versus 14.1%, p = 0.078) were comparable in both groups. CONCLUSION ISR leads to increased bowel incontinence rate and increased anal pain, without affecting the grade of low anterior resection syndrome, fecal urgency, and clustering. LAR might be the preferred sphincteric-preserving approach when negative resection margins and a safe anastomosis are guaranteed. Patients should be fully informed about potential functional impairment after sphincter-preservation procedures.

Abstract
PURPOSE This study aimed to compare the oncological and functional outcomes following intersphincteric resection (ISR) with transverse coloplasty pouch (TCP) or straight coloanal anastomosis (SCAA) for low rectal cancer. METHODS A single-center retrospective analysis was performed on patients with low rectal cancer who received ISR between January 2016 and June 2021. The primary endpoint was to compare the outcomes of bowel function within 1 year, 1 to 2 years, and 2 years after ileostomy closure in patients undergoing two different bowel reconstruction procedures (TCP or SCAA). The postoperative complications and oncological results were also compared between the two groups. RESULTS A total of 235 patients were enrolled in this study (SCAA group: 166; TCP group: 69). There was no significant difference in complications, including grades A-C anastomotic leakage (9.6% vs 15.9%), 3-year local recurrence rates (6.1% vs 3.9%), disease-free survival (82.4%vs 83.8%), or overall survival (94.1% vs 94.7%) between the two groups. Two years after ileostomy closure, 52.7% of patients in the SCAA group were assessed as having major low anterior resection syndrome (LARS), which was significantly higher than the 25.9% of patients in the TCP group (P = 0.014), but no difference was found prior to 2 years. Similar differences were seen in Wexner scores 2 years after surgery (P = 0.032). Additionally, TCP was an independent protective factor for postoperative bowel function as measured by both the LARS (OR, 0.28; 95% CI, 0.10-0.82; p = 0.020) and Wexner scoring (OR, 0.28; 95% CI, 0.09-0.84; p = 0.023). CONCLUSION This study suggests that TCP is a safe technique that may decrease bowel dysfunction after ISR for low rectal cancer compared with SCAA 2 years after ileostomy closure.

Abstract
PURPOSE To determine whether anastomotic leakage (AL) following intersphincteric resection (ISR) for ultralow rectal cancer (uLRC) is associated with long-term negative outcomes. METHODS Between June 2011 and January 2022, 236 consecutive patients who underwent ISR with diverting ileostomy for uLRC were included. The primary outcome was long-term clinical consequences of AL, including chronic stricture, stoma reversal, and oncological and functional results. RESULTS Forty-one (17.4%) patients developed symptomatic AL, whereas only two (0.8%) required re-laparotomy due to severe leakage. Patients with leaks had a significantly increased incidence of chronic stricture (29.3% vs. 8.7%, P = 0.001) and stoma non-reversal (34.1% vs. 4.6%, P < 0.0001) than controls. The severe consequences were particularly common in patients with anastomotic separation, resulting in 60% of those presenting with chronic stricture and 50% ending up with stoma non-reversal. After a median follow-up of 59 (range, 7-139) months, AL did not compromise long-term oncological outcomes, including tumor recurrence (9.8% vs. 5.6%, P = 0.3), 5-year disease-free, and overall survival (73.4% vs. 74.8% and 85.1% vs. 85.4%, P = 0.56 and P = 0.55). A total of 149 patients with bowel continuity who completed self-assessment questionnaires were enrolled for functional evaluation. The median follow-up was 24 (range, 12-94) months after ileostomy reversal, and functional results were comparable between patients with and without leaks. CONCLUSION AL is an unfortunate reality for patients who underwent ISR for uLRC, but the rate of severe leakage is limited. Leaks contribute to possible adverse impacts on chronic stricture and stoma non-reversal, especially for patients with anastomotic separation. However, long-term oncological and functional results may not be compromised. TRIAL REGISTRATION Chictr.org.cn identifier: ChiCTR-ONC-15007506 and ChiCTR2100051614.

Abstract
Neorectal prolapse following proctectomy for cancer has seldom been reported and treatment has mostly consisted in the resection of the prolapse via a perineal approach. Management of a patient with neorectal J-pouch prolapse using mesh sacral pexy via an abdominal approach is reported. By analogy with native rectal prolapse due to pelvic static disorders, laparoscopic mesh sacral pexy is likely to afford the same advantages of low morbidity and durability when applied to neorectal prolapse following rectal cancer surgery.

Abstract
BACKGROUND Anus-preserving surgery for low rectal cancer has always been a serious difficulty for surgeons. Transanal total mesorectal excision (TaTME) and laparoscopic intersphincteric resection (ISR) are commonly used Anus-preserving surgeries for low rectal cancer. The aim of this study was to compare the clinical use of two surgical methods. METHODS A total of 152 patients with low rectal cancer were treated with taTME in 75 cases and ISR in 77 cases. After propensity score matching, 46 patients in each group were included in the study. Perioperative outcomes, anal function scores (Wexner incontinence score) and quality of life scores (EORTC QLQ C30, EORTC QLQ CR38) at least 1 year after surgery were compared between the two groups. RESULTS There were no significant differences between the two groups in terms of surgical outcomes, pathological examination of surgical specimens, postoperative recovery, and postoperative complications, except for patients in the taTME group who had their indwelling catheters removed later. Anal Wexner incontinence score was lower in taTME group than ISR group (P < 0.05). On the EORTC QLQ-C30 scale, the physical function and role function scores in the ISR group were lower than those in the taTME group (P < 0.05), while the fatigue, pain symptoms, and constipation scores in the ISR group were higher than those in the taTME group (P < 0.05). On the EORTC QLQ-CR38 scale, the scores of gastrointestinal symptoms and defecation problems in the ISR group were higher than those in the taTME group (P < 0.05). CONCLUSION Compared with ISR surgery, taTME surgery is comparable in terms of surgical safety and short-term efficacy, and has better long-term anal function and quality of life. From the perspective of long-term anal function and quality of life, taTME surgery is a better surgical method for the treatment of low rectal cancer.

Abstract
BACKGROUND Intersphincteric resection (ISR), the ultimate anus-preserving technique for ultralow rectal cancers, is an alternative to abdominoperineal resection (APR). The failure patterns and risk factors for local recurrence and distant metastasis remain controversial and require further investigation.
AIM To investigate the long-term outcomes and failure patterns after laparoscopic ISR in ultralow rectal cancers.
METHODS Patients who underwent laparoscopic ISR (LsISR) at Peking University First Hospital between January 2012 and December 2020 were retrospectively reviewed. Correlation analysis was performed using the Chi-square or Pearson's correlation test. Prognostic factors for overall survival (OS), local recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) were analyzed using Cox regression.
RESULTS We enrolled 368 patients with a median follow-up of 42 mo. Local recurrence and distant metastasis occurred in 13 (3.5%) and 42 (11.4%) cases, respectively. The 3-year OS, LRFS, and DMFS rates were 91.3%, 97.1%, and 90.1%, respectively. Multivariate analyses revealed that LRFS was associated with positive lymph node status [hazard ratio (HR) = 5.411, 95% confidence interval (CI) = 1.413-20.722, P = 0.014] and poor differentiation (HR = 3.739, 95%CI: 1.171-11.937, P = 0.026), whereas the independent prognostic factors for DMFS were positive lymph node status (HR = 2.445, 95%CI: 1.272-4.698, P = 0.007) and (y)pT3 stage (HR = 2.741, 95%CI: 1.225-6.137, P = 0.014).
CONCLUSION This study confirmed the oncological safety of LsISR for ultralow rectal cancer. Poor differentiation, (y)pT3 stage, and lymph node metastasis are independent risk factors for treatment failure after LsISR, and thus patients with these factors should be carefully managed with optimal neoadjuvant therapy, and for patients with a high risk of local recurrence (N + or poor differentiation), extended radical resection (such as APR instead of ISR) may be more effective.

Abstract
Aim of this study was to compare operative, long-term oncological and functional outcomes of laparoscopic (LISR) and robotic (RISR) intersphincteric resection in low-lying rectal cancer. Retrospective analysis of prospectively maintained database was performed. 115 cases (LISR, n = 55; RISR, n = 60) were performed by a single surgeon (January 2011-January 2020). Clinical characteristics did not differ between the groups. Operating time was longer in RISR (160.0 ± 45.7 vs. 205.0 ± 36.5 min, p = 0.035). There was no conversion in RISR, whereas in LISR, two patients (3.6%) converted to open surgery. Complete mesorectum was 61.8% and 83.3% for LISR and RISR (p = 0.046), respectively. Circumferential radial margin involvement was 10.9% and 8.3% in LISR and RISR (p = 0.365), respectively. Median follow-up was 82.8 (30-138) months for LISR and 83.6 (30-138) months for RISR. Three-, five-, and seven-year overall survival rates (OS) for LISR and RISR were: 88.6%, 80.4%, 73.4% and 90.4%, 86.3%, 76.9%, respectively. Three-, five-, and seven-year disease-free survival (DFS) rates for LISR and RISR were 80.5%, 75.2%, 70.4% and 84.4%, 81.4%, 79.8% (p = 0.328), respectively. Three-, five-, and seven-year local recurrence-free survival rates in LISR and RISR were: 96.1%, 92.6%, 88.4% and 96.7%, 94.2%, 90.4% (p = 0.573), respectively. Mean Wexner score for LISR (n = 32) and RISR (n = 40) was: 10.5 ± 4.7 and 9.8 ± 4.2 (p = 0.782), respectively. Colostomy-free survival in LISR and RISR was: 3 years 94.5%/95.2%, 5 years 89.1%/91.7%, and 7 years 83.6%/85.0%. RISR is associated with better mesorectal integrity, no conversion, and lower postoperative complication rate. RISR has longer operation time. Oncological and anorectal functional outcomes are similar in both groups.

Abstract
Intersphincteric resection (ISR), as an ultra-low sphincter-preserving operation, is widely used in clinical practice at present. ISR can allow some patients with very low rectal cancer to avoid the pain of anal resection while ensuring oncological efficacy. However, the procedure of ISR requires wider intersphincteric dissection which may cause nerve damage, and the removal of partial or total internal anal sphincter as an "inherent defect" of ISR can result in poor anal function postoperatively. Based on the in-depth understanding of regional anatomy and physiological function, the author proposed a new functional sphincter preservation operation for very low rectal cancer-conformal sphincter preservation operation (CSPO) which has achieved good outcome in clinical practice. This article will revisit the brief history of rectal cancer surgery and discuss the main mechanisms underlining the poor anal function after ISR. Based on the anatomical study of the pelvic floor and anal canal, CSPO can improve the postoperative anal function of very low rectal cancer patients by reducing the damage of the autonomic nerves, receptor corpuscles and muscle fibers in the intersphincteric space, retaining more dentate line and internal sphincter with the design of resection line of tumor lower border under direct vision, and elevating the anastomosis height. At the same time, the future treatment prospect of low rectal cancer is envisioned.

Abstract
Background The operative results of different approaches for the laparoscopic intersphincteric resection (LAISR) of low rectal cancer vary, and the patient characteristics associated with the best outcomes for each procedure have not been reported. We compared the efficacy of different approaches for LAISR of low rectal cancer and discussed the surgical indications for each approach. Methods We retrospectively reviewed data from 235 patients with low rectal cancer treated via LAISR from October 2010 to September 2016. Patients underwent either the transabdominal approach for ISR (TAISR, n = 142), the transabdominal perineal approach for ISR (TPAISR, n = 57), or the transanal pull-through approach for ISR (PAISR, n = 36). Results The PAISR and TAISR groups exhibited shorter operation times and less intraoperative blood loss than the TPAISR group. The anastomotic distance was shorter in the PAISR and TPAISR groups than in the TAISR group. No differences in the ability to perform radical resection, overall complications, postoperative recovery, Wexner score recorded 12 months after ostomy closure, 3-year disease-free survival, local recurrence-free survival, distant metastasis-free survival, or overall survival (OS) were observed among the three groups. Conclusions TAISR, TPAISR, and PAISR have unique advantages and do not differ in terms of operation safety, patient outcomes, or anal function. TPAISR requires a longer time to complete and is associated with more bleeding and a slower recovery of anal function. PAISR should be considered when TAISR cannot ensure a negative distal margin and the tumor and BMI are relatively small; otherwise, TPAISR is required.

Abstract
BACKGROUND Da Vinci® Single Port (dvSP) was recently developed. Its application in colorectal surgery is under investigation. The aim of this study was to explore the safety and feasibility of dvSP for intersphincteric (dvSP-ISR), right colectomy (dvSP-RC), and transverse colectomy (dvSP-TC). Surgical indication and short-term results were analyzed. METHODS All consecutive patients from a prospective database of patients who underwent dvSP-ISR, dvSP-RC, and dvSP-TC at Korea University Anam Hospital from November 2020 to December 2021, were analyzed. Perioperative, pathological, and oncological short-term outcomes were analyzed. RESULTS A total of 7 dvSP-ISR, 5 dvSP-RC, and 1 dvSP-TC were performed. Median age was 56.0 (55.0-61.0) years for the dvSP-ISR and 54.0 (44.7-63.5) years for the dvSP-RC/TC. Median body mass index was 22.8 (17.1-24.8) kg/m2 for the dvSP-ISR and 23.6 (20.8-26.9) kg/m2 for the dvSP-RC/TC. All dvSP-ISR patients received neoadjuvant long-course chemoradiotherapy, including one patient with squamocellular carcinoma who was treated with 5-fluorouracil (5-FU)/mitomycin. All other patients, excluding one dvSP-RC patient with Crohn's disease, had an adenocarcinoma. Median operation time was 280 (240-370) minutes for the dvSP-ISR and 220 (201-270) minutes for the dvSP-RC/TC. Estimated blood loss was insignificant. No intraoperative complications or conversions to multiport/open surgery was reported. Median post-operative stay was 7.0 (6.0-10.0) days for the dvSP-ISR and 5.0 (4.0-6.7) days for the dvSP-RC/TC. Quality of mesorectum was complete for six patients, and nearly complete for one. Median number of retrieved lymph nodes were 21 (17-25) for the dvSP-ISR and 28 (24-49) for the dvSP-RC/TC. Proximal and distal resection margins were tumor free. Four patients experienced post-operative complications not related to the platform which were: ileus, voiding dysfunction, infected pelvic hematoma, and wound infection. Median follow-up was 9 (6-11) months and 11 (7-17) months for the dvSP-ISR and dvSP-RC/TC, respectively. Two patients had systemic recurrence; all others were tumor free. CONCLUSIONS The dvSP platform is safe and feasible for intersphincteric resection with right lower quadrant access, and right/transverse colectomy with suprapubic access. Further studies are needed to evaluate benefit differences compared to multiport robotic platform.

Abstract
Objective: To evaluate the safety and efficacy of distal rectal transection by using transanterior obturator nerve gateway (TANG) in laparoscopic radical resection for lower rectal cancers. Methods: A descriptive case series study was performed. Inclusion criteria: (1) patients with primary rectal adenocarcinoma, with the distance of 3-5 cm from tumor to anal verge, with normal anal function before surgery and a desire to preserve anus; (2) laparoscopic radical resection of rectal cancer was performed and the distal rectum was transected using TANG approach. Exclusion criteria: (1) patients with distant metastasis or receiving palliative surgery; (2) the distal rectum was transected using non-TANG approach; (3) patients receiving combined multiple organs resection; (4) patients complicated with other tumors requiring additional treatment during the study. Clinicopathological data of 50 patients with low rectal cancer undergoing laparoscopic resection using TANG approach between January 2019 and December 2020 in Peking University First Hospital were retrospectively collected. Perioperative conditions, length of specific pelvic lines, additional angle and postoperative short-term outcomes were observed and described. Additional angle was defined as the angle between the simulated stapling line with the traditional approach and the real stapling line with the TANG approach. Data following normal distribution were presented as Mean±SD, or M [quartile range (Q(R))] otherwise. Results: All the patients successfully completed laparoscopic surgery without transferring to open or transanal surgery. The median operative time was 193 (80) min and blood loss was 50 (58) ml. All tumors received R0 resection with the distance from the tumor to distal resection margin of 1.7 (0.4) cm and the anastomotic height of 2.0 (0.1) cm. Rectal transection was completed by one cartridge in 52.0% of the cases (26/50) and two cartridges in 48.0% (24/50). Length of the stapling line was 6.6 (1.5) cm. The time to construct the gateway was 8.0 (6.0) min. The vessel damage occurred in 4.0% of the cases (2/50) and none of the cases encountered obturator nerve damage. Inlets of the pelvis in TANG and traditional approach were (9.9±1.3) cm vs. (7.2±1.1) cm (t=24.781, P<0.001). Additional angle of TANG was (15±2) °. The transecting positions on the midline and right edge of the rectum specimen by TANG were 0.6 (0.2) cm and 1.0 (0.2) cm lower than those by the traditional approach. One case (2.0%) died of pulmonary infection on the 17th day after surgery, 2 cases (4.0%) received re-operation and 14 cases (28.0%) had postoperative complications, including anastomotic leakage (7/50, 14.0%), urinary retention (6/50, 12.0%), pelvic infection (2/50, 4.0%) and ileus (2/50, 4.0%). The median postoperative hospital stay was 12 (6) days. Conclusions: Laparoscopic distal rectal transection by using TANG approach is safe and effective in the treatment of low rectal cancer. As an alternative rectal transecting method, TANG has advantages especially for the obese and those with a contracted pelvis and ultralow rectal cancers.

Abstract
BACKGROUND Intersphincteric resection (ISR) has been proposed to offer sphincter-sparing solution for patients with ultra-low rectal cancer. However, complete and accurate concepts about the intersphincteric space (ISS) related anatomy are not demonstrated clearly. This study aimed to provide a comprehensive description about the anatomic structure of ISS related to ISR. METHODS This was a descriptive morphological study. 28 pelvic specimens were obtained from body donors. Macroscopic and microscopic observation of ISS was performed via gross anatomy, plastinated sections and histologic staining. The anatomical parameters of the anal canal were measured. Images of laparoscopic ISS dissection procedures were real-timely captured during ISR. RESULTS The hiatal ligament, microvessels on supra fascia of LAM and rectal longitudinal muscle at the level of anorectal ring, especially at 1, 5, 7, and 11o'clock, could be the preferred entrance of ISS. The conjoint longitudinal muscle (CLM), the major component of ISS, was the continuum of the rectal longitudinal muscle and got reinforcement from the elastic fibers from LAM and EAS. Microvessels and neuro tissues were also found in ISS. The ISS was split into two spaces by the CLM in the middle and might subjectively be divided into three segments according to its different compositions. The length and width of ISS varied from different segments and directions. CONCLUSIONS We provided a systemic description of boundaries, contents and topographic structure of ISS, which may help proper determination of surgical approaches and dissection planes during ISR.

Abstract
Introduction Dysfunctions such as mucosal prolapse occur after intersphincteric resection (ISR) to treat lower rectal cancer, even when it is possible to preserve the anus. Method We analyzed the data of 12 patients with rectal or colonic prolapse who underwent the Gant-Miwa-Thiersch procedure between March 2017 and May 2021. Result There were no severe postoperative complications or recurrences. Case presentation A 75-year-old Japanese man initially underwent ISR and had mucosal prolapse nine months after his initial operation. We performed the Gant-Miwa-Thiersch procedure for colonic mucosal prolapse after ISR. Surgical procedure Our procedure is a perineal plication method of prolapsed colonic mucosa with nylon wiring (The Gant-Miwa procedure), using a 1-nylon wire encircled three times to straighten the anal canal, with a cord inserted above the internal sphincter muscle (Thiersch procedure). Discussion Mucosal plication is performed via the Gant-Mowa or Delorme procedure to reduce the risk of recurrence. However, mucosal plication can be performed many times. Our Thiersch procedure involves encircling and straightening the anal canal with a 1-nylon wire to fix the new internal anal sphincter. In conclusion, the Gant-Miwa-Thiersch procedure for rectal and colonic mucosal prolapse, especially after ISR, is a viable treatment option. Our procedure is The Gant-Miwa procedure, using a 1-nylon wire encircled three times (Thiersch procedure). Mucosal plication is performed via the Gant-Mowa or Delorme procedure to reduce the risk of recurrence. The Gant-Miwa-Thiersch procedure for rectal and colonic mucosal prolapse, especially after ISR, is a viable treatment option.

Abstract
Intersphincteric resection (ISR) is the ultimate anus-sparing technique for low rectal cancer and is considered an oncologically safe alternative to abdominoperineal resection. The application of the robotic approach to ISR (RISR) has been described by few specialized surgical teams with several differences regarding approach and technique. This review aims to discuss the technical aspects of RISR by evaluating point by point each surgical controversy. Moreover, a systematic review was performed to report the perioperative, oncological, and functional outcomes of RISR. Postoperative morbidities after RISR are acceptable. RISR allows adequate surgical margins and adequate oncological outcomes. RISR may result in severe bowel and genitourinary dysfunction affecting the quality of life in a portion of patients.

Abstract
Intersphincteric resection (ISR) involves the anatomy of hiatal ligament, internal and external sphincter and conjoined longitudinal muscle. The hiatal ligament is actually a branch of the longitudinal muscle of rectum, shown as an uneven ring attached to the levator ani muscle. The internal sphincter is the end of the circular muscle of rectum which begins at the level of hiatal ligament formation. The distance from the upper boundary of internal sphincter to dentate line is significantly different among individuals. Although there is adipose tissue in the space between the internal and external sphincters, no evidence of mesentery structure in the anal canal is found as in the rectum. The conjoined longitudinal muscle is the remaining branch of the longitudinal muscle, whose return passes through the external sphincter and ends at the anococcygeal ligament/coccyx after reaching the anal margin. The synergistic action of conjoined longitudinal muscle and the hiatal ligament participates in the defecation process. The individualized difference of ISR-related anatomy affects the operation, especially the anastomosis.

Abstract
Radical resection for low rectal cancer is the mainstay among the treatment modalities. Intersphincteric resection (ISR) is considered a relatively new but effective surgical treatment for low-lying rectal tumor. As the sphincter preserving techniques get popularized, we notice uncommon complication associated with it in the form of rectal mucosal prolapse. We presented 2 rare cases that developed neorectal mucosa prolapse after ISR a complication following low rectal cancer surgery. Although ISR is a safe and effective surgical technique for low rectal cancer, it should be considered to correct modifiable possible risk factors. Also, Delorme procedure is good option for management of neorectal mucosal prolapse.

Abstract
INTRODUCTION Intersphincteric resection (ISR) is the ultimate anal-sparing technique as an alternative to abdominoperineal resection in selected patients. Oncological safety is still debated. This study analyses long-term oncological results and evaluates risk factors for local recurrence (LR) and overall survival (OS) after minimally-invasive ISR. MATERIALS AND METHODS Retrospective single-center data were collected from a prospectively maintained colorectal database. A total of 161 patients underwent ISR between 2008 and 2018. OS and local recurrence-free survival (LRFS) were assessed using Kaplan-Meier analysis (log-rank test). Risk factors for OS and LRFS were assessed with Cox-regression analysis. RESULTS Median follow-up was 55 months. LR occurred in 18 patients. OS and LRFS rates at 1, 3, and 5 years were 96%, 91%, and 80% and 96%, 89%, and 87%, respectively. Tumor size (p = 0.035) and clinical T-stage (p = 0.029) were risk factors for LRFS on univariate analysis. On multivariate analysis, tumor size (HR 2.546 (95% CI: 0.976-6.637); p = 0.056) and clinical T-stage (HR 3.296 (95% CI: 0.941-11.549); p = 0.062) were not significant. Preoperative CEA (p < 0.001), pathological T-stage (p = 0.033), pathological N-stage (p = 0.016) and adjuvant treatment (p = 0.008) were prognostic factors for OS on univariate analysis. Preoperative CEA (HR 4.453 (95% CI: 2.015-9.838); p < 0.001) was a prognostic factor on multivariate analysis. CONCLUSIONS This study confirms the oncological safety of minimally-invasive ISR for locally advanced low-lying rectal tumors when performed in experienced centers. Despite not a risk factor for LR, tumor size and, locally advanced T-stage with anterior involvement should be carefully evaluated for optimal surgical strategy. Preoperative CEA is a prognostic factor for OS.

Abstract
BACKGROUND Intracorporeal rectal transection at the anorectal junction for ultralow rectal cancer is technically difficult due to pelvic width and limited roticulation, which might require a transanal transection or an oblique transection with multiple firings. These procedures were reported to be associated with the increased risk of morbidity. To address these problems, we presented a novel technique Transanterior Obturator Nerve Gateway (TANG) to transect rectum for ultralow rectal cancer and evaluated its safety and feasibility in this study. METHODS A total of 210 consecutive patients who underwent laparoscopic coloanal anastomosis with or without partial intersphincteric resection (CAA/pISR) for rectal cancers between January 2017 and January 2020 were included. Eighty of these patients were analyzed using propensity score matching (PSM). The perioperative characteristics, TANG-related variables, and genitourinary and anal function outcomes were analyzed. RESULTS Among these enrolled patients, 170 patients underwent traditional transection, and 40 underwent TANG transection; the patients were matched to include 40 patients in each group by PSM. After PSM, there were no significant differences in the operating time (p = 0.351) or bleeding volume (p = 0.474) between the two groups. However, the TANG group had fewer cases of conversion to transanal transection (0 vs. 13, p < 0.001). Moreover, the patients in TANG group had a more desirable transection with longer distal resection margin (1.7 vs. 1.1 cm, p < 0.001), shorter stapling line (6.6 vs. 10.3 cm, p < 0.001) and fewer stapler firings (p < 0.001). The overall postoperative complication rates and genitourinary and anal function outcomes were not significantly different between the two groups. CONCLUSIONS The TANG approach appears to be a safe, feasible and effective approach for intracorporeal ultralow rectal transection with more distal resection, more vertical transection and fewer stapler firings.

Abstract
PURPOSE Severe defecation disorder occurs frequently in coloanal anastomosis for low rectal cancer, and may affect quality of life. Sacral neuromodulation (SNM) has been reported to be successful after rectal resection, but there are no results for patients treated with intersphincteric resection (ISR). METHODS A retrospective single-center study of SNM was performed for patient with defecation disorder following ISR. Pre- and post-treatment bowel frequencies, fecal incontinence episodes, and Wexner, LARS and FIQL scores were assessed to evaluate the efficacy. A good response was defined as ≥ 50% reduction of bowel frequency per day or fecal incontinence episodes per week. RESULTS 10 patients (7 males, mean age 67.5 years) underwent SNM. All patients had severe fecal incontinence with a median Wexner score of 15 (13-20) and a median LARS score of 41 (36-41). The Wexner score improved after SNM, but not significantly (p = 0.06). LARS and FIQL scores significantly improved after SNM (p = 0.02, p = 0.01). At the end of follow-up, the good response rate was 40%. Three cases without a good response required creation of a permanent stoma. CONCLUSION Seven out of 10 patients did not require a permanent colostomy after SNM. SNM should be considered before performing a permanent colostomy.

Abstract
BACKGROUND Although total mesorectal excision (TME) is regarded as a standard procedure for rectal cancer, technical definition and evaluation method have not yet been investigated for intersphincteric resection (ISR). This study was performed to introduce a complete ISR procedure, and to assess whether total intersphincteric longitudinal muscle excision (TILME) facilitated the completeness of ISR and reduced recurrence. METHODS A total of 1080 patients with rectal adenocarcinoma who underwent robot-assisted low anterior resection (LAR) over 10 years were consecutively enrolled. Propensity-score matching of the two LAR groups (ISR vs LAR group, 1:1) and three ISR subgroups (partial vs subtotal vs total ISR subgroup, 2:2:1) was performed by strict adjustment of baseline characteristics. Archived specimens and video-/photo-records were reevaluated to examine completeness of TILME. RESULTS Complete-TILME was performed in 84.5% of patients who underwent ISR. Multivariate analysis showed that incomplete-TILME was the only parameter independently associated with increased 5-year cumulative local recurrence (odds ratio = 23.385; 95% confidence interval = 1.492-366.421; p = 0.03), and that incomplete-TILME was independently associated with adipose tissue surrounding the intersphincteric longitudinal muscle, coloanal anastomosis, and total ISR (p < 0.001-0.05). Although mean incontinence scores and anorectal manometry deteriorated to some degree 12-24 months after surgery in all patients, they remained acceptable. The 5-year cumulative DFS (74.1% vs 60%, p = 0.18) and OS (85.9% vs 70%, p = 0.10) rates tended to be higher in patients with complete than incomplete-TILME. CONCLUSIONS The completeness of TILME appears to be an independent indicator of complete ISR, reducing local recurrence following lower rectal cancer surgery.

Abstract
PURPOSE Laparoscopic surgery allows minimally invasive treatment of rectal cancer, and needlescopic surgery (NS) offers even more minimally invasive operations beyond the scope of conventional laparoscopic surgery (CS). The aim of this study was to compare short-term outcomes of NS for intersphincteric resection (ISR) or abdominoperineal resection (APR) to treat anal or rectal cancer without an abdominal incision for specimen extraction and to measure abdominal wound pain compared to CS. METHODS Between September 2014 and December 2016, a total of 134 patients underwent laparoscopic ISR or APR. Of these, 26 patients underwent NS, and 108 patients underwent CS. Postoperative abdominal wound pain was estimated using the numerical rating scale. Short-term outcomes were compared between NS and CS. RESULTS No conversion to CS or open surgery was required. Median operation time was significantly shorter with NS (295 min) than with CS (331.5 min; p = 0.020). Median estimated blood loss was significantly lower with NS (30 ml) than with CS (50 ml; p = 0.011). Postoperative pain score on postoperative day (POD)5 was significantly lower with NS than with CS (p = 0.025), and frequencies of analgesic use were significantly lower with NS than with CS on POD0, POD2, and POD3 (p = 0.032, p = 0.017, p = 0.045, respectively). The postoperative complications occurred at similar frequencies between groups (p = 0.655). CONCLUSION NS for ISR or APR offers comparable short-term outcomes to CS, with better pain outcomes.

Abstract
BACKGROUND Intersphincteric resection (ISR) has been increasingly used as the ultimate sphincter-preserving procedure in extremely low rectal cancer. The most critical complication of this technique is anastomotic leakage. The incidence rate of anastomotic leakage after ISR has been reported to range from 5.1% to 20%.
AIM To investigate risk factors for anastomotic leakage after ISR based on clinicopathological variables and pelvimetry.
METHODS This study was conducted at Department of Colorectal Surgery, Japanese Red Cross Medical Center, Tokyo, Japan, with a total of 117 patients. We enrolled 117 patients with extremely low rectal cancer who underwent laparotomic and laparoscopic ISRs at our hospital. We conducted retrospective univariate and multivariate regression analyses on 33 items to elucidate the risk factors for anastomotic leakage after ISR. Pelvic dimensions were measured using three-dimensional reconstruction of computed tomography images. The optimal cutoff value of the pelvic inlet plane area that predicts anastomotic leakage was determined using a receiver operating characteristic (ROC) curve.
RESULTS We observed anastomotic leakage in 10 (8.5%) of the 117 patients. In the multivariate analysis, we identified high body mass index (odds ratio 1.674; 95% confidence interval: 1.087-2.58; P = 0.019) and smaller pelvic inlet plane area (odds ratio 0.998; 95% confidence interval: 0.997-0.999; P = 0.012) as statistically significant risk factors for anastomotic leakage. According to the receiver operating characteristic curves, the optimal cutoff value of the pelvic inlet plane area was 10074 mm2. Narrow pelvic inlet plane area (≤ 10074 mm2) predicted anastomotic leakage with a sensitivity of 90%, a specificity of 85.9%, and an accuracy of 86.3%.
CONCLUSION Narrow pelvic inlet and obesity were independent risk factors for anastomotic leakage after ISR. Anastomotic leakage after ISR may be predicted from a narrow pelvic inlet plane area (≤ 10074 mm2).

Abstract
PURPOSE Mucosal prolapse at the site of anastomosis is a long-term complication unique to ISR. It reduces the QOL of patients due to a worsened anal function and local symptoms around the anus. We herein sought to assess the surgical outcomes after Delorme surgery for these patients. METHODS ISR was performed in 720 patients with low rectal cancer between January 2001 and March 2019 at the National Cancer Center Hospital East. Among these patients, the 33 (4.5%) who underwent initial Delorme surgery for postoperative colonic mucosal prolapse were identified from the medical records and then were analyzed retrospectively. We estimated the anal function using Wexner's incontinence score and assessed whether local anal symptoms due to the prolapse improved postoperatively. RESULTS Stoma closure was performed before Delorme surgery in 15 (45.5%) patients, and we compared the preoperative and postoperative anal function in these patients. The average Wexner's incontinence score changed from 15.1 before to 12.9 after Delorme surgery. Local symptoms around the anus improved in all 33 (100%) patients. Recurrence of colonic mucosal prolapse occurred in 5 patients (15%), and Delorme surgery was reperformed in these cases. CONCLUSION Delorme surgery for colonic mucosal prolapse following ISR has clinical benefits for both improving anal local symptoms and slightly improving the anal function.

Abstract
Locally advanced rectal cancer often requires an extended resection beyond the total mesorectal excision plane (bTME) to obtain clear resection margins. We classified three types of bTME rectal cancer following local disease diffusion: radial (adjacent pelvic organs), lateral (pelvic lateral lymph nodes) and longitudinal (below 3.5 cm from the anal verge, submitted to intersphincteric resection). The primary aim of this study was to evaluate the application of robotic surgery to the three types of bTME regarding the short and long-term oncological outcomes. Secondary aim was to identify survival prognostic factors for bTME rectal cancers. A total of 137 patients who underwent robotic-assisted bTME procedures between 2008 and 2018 were extracted from a prospectively collected database. Patient-related, operative and pathological factors were assessed. Morbidity was moderately high with 66% of patients reporting postoperative complications. Median follow up was 47 months (IQR, 31.5-66.5). Local recurrence rate was 15.3% with a statistical difference between the three types of bTME (p = 0.041). Disease progression/distant metastasis rate was 33.6%. Overall survival was significantly different (p = 0.023) with 1- and 3-years rates of: 77.8% and 55.0% (radial; n = 19); 96.6% and 84.8% (lateral; n = 30); 97.7% and 86.9% (longitudinal; n = 88). No statistical difference was observed for disease-free survival (p = 0.897). Local recurrence-free survival was significantly different between the groups (p = 0.031). Multivariate analysis showed that (y)pT (p = 0.028; HR (95% CI) 5.133 (1.192-22.097)), (y)pN (p = 0.014; HR (95% CI) 2.835 (1.240-6.482)) and type of bTME were associated to OS whilst (y)pT (p = 0.072) and type of bTME were not associated to LRFS.

Abstract
PURPOSE To investigate the frequency of exfoliated cancer cells and the efficacy of rectal washout during intersphincteric resection (ISR) in patients not receiving chemoradiotherapy (CRT) for very low rectal cancer. METHOD The subjects of this prospective study were 16 consecutive patients who underwent ISR without CRT for very low rectal cancer. Brushing cytology of the posterior anorectal wall was performed twice in each step of the ISR procedure and the samples were sent for blind cytological examination to identify exfoliated cancer cells. RESULTS Exfoliated cancer cells were identified in 9 of 13 patients (69%) preoperatively. The number of cancer cells identified after abdominal total mesorectal dissection decreased significantly from 94% (15/16) to 25% (4/16) after transanal irrigation with 2000 mL saline (p < 0.001). No cancer cells were identified after swabbing the anal wall following transanal dissection with purse-string closure of the distal stump. No suture-line recurrence was found during a median follow-up duration of 6 years. CONCLUSION Exfoliated cancer cells, confirmed in 94% of patients after total mesorectal excision, could be eliminated by performing rectal irrigation after clamping the rectum proximal to the tumor and swabbing the anorectal wall during ISR.

Abstract
Objective: To explore the technical characteristics and short-term clinical efficacy of robotic-assisted intersphincteric resection (ISR) for patients with low rectal cancer. Methods: A retrospective cohort study was used. Inclusion criteria: (1) rigid colonoscopy showed lower margin of the tumor ≤5 cm from the anal verge; (2) preoperative rectal MRI or endorectal ultrasound revealed staging T1-2, or T3 patients receiving concurrent chemoradiotherapy; (3) patients less than 70 years old with good function of anal sphincter before surgery; (4) no synchronous multiple primary carcinoma, and no distant metastasis; (5) the method of operation was agreed by the patient. Exclusion criteria: (1) T4 stage tumors; (2) sphincter dysfunction before operation; (3) recurrent tumors; (4) lower edge of tumors beyond the dentate line; (5) death due to non-rectal cancer during follow-up and unsatisfactory follow-up data. The clinical data of 21 patients with low rectal cancer meeting inclusion criteria undergoing robotic-assisted ISR at our department from January 2015 to June 2018 were collected. Parameters during and after operation were observed. Anorectal manometry was performed at 3, 6, and 12 months after the operation, and anal function was evaluated at 3, 6, and 12 months after the closure of the stoma by Kirwan classification and Wexner fecal incontinence score. The key steps of the operation are as follows: according to the principle of total mesorectal excision, the robot continued to enter into the levator ani hiatusdistally, and dissectin the sphincter space; according to the scope of sphincter resection, ISRwas divided into partial ISR, subtotal ISR, and total ISR; subtotal and total ISR usually needed to be combined with transanal pathway. The reconstruction of digestive tract was performed by double stapler anastomosis under laparoscope orhand-sewnanastomosis under direct vision, and preventive ileostomy was completed in the right lower abdomen. Results: Of 21 patients, 13 were male and 8 were female with mean age of (57.5±16.3) years. All the patients successfully completed the operation without conversion to laparotomy. Fourteen cases (66.7%) adopted partial ISR through complete transabdominal approach, 6 cases (28.6%) adopted the subtotal ISR through combined transabdominal and transanal approachs, and 1 case (4.8%) adopted the total ISR through the combined transabdominal and transanal approachs. The total operation time was (213.1±56.3) minutes, including (27.3±5.4) minutes for mechanical arm installation and (175.7±51.6) minutes for robotic operation. The amount of intraoperative hemorrhage was (62.8±23.2) ml, and no blood transfusion was performed in any patient. All patients underwent prophylactic ileostomy, and the stoma was closed 3-6 months after the operation. Except one case of anastomotic leakage, all other stomas were closed successfully. The postoperative hospitalization time was (7.6±2.2) days, and time to fluid intake was (3.3±0.9) days. One case of anastomotic leakage, one case of anastomotic stenosis, one case of inflammatory external hemorrhoids and one case of urinary retention occurred after surgery,and all of them were cured by conservative treatment. The mean diameter of tumors was (2.9±1.2) cm, and the number of harvested lymph node was 12.8 ± 3.3. In the whole group, the circumcision margin was negative, the proximal margin was (12.2 ± 2.1) cm, the distal margin was (1.1 ± 0.4) with all negative, and the R0 resection rate was 100%. The results of anorectal manometry showed that the preoperative rest pressure, rectal maximum squeeze pressure, initial sensory volume and maximum tolerated volume were (45.19±8.46) mmHg, (128.18±18.80) mmHg, (44.33±10.11) ml and (119.00±19.28) ml, respectively;these parameters reduced significantly 3 months after operation and they were (23.44±5.54) mmHg, (93.72±12.15) mmHg, (17.72±5.32) ml and (70.44±10.9) ml, respectively. The differences were statistically significant (all P<0.001). The resting pressure and the rectal maximum squeeze pressure returned to preoperative levels 12 months after operation, which were (39.33±6.64) mmHg and (120.58±16.47) mmHg, respectively (both P>0.05), while the initial sensory volume and the maximum tolerated volume failed to reach the preoperative state, which were (30.67±7.45) ml and (92.25±10.32) ml, respectively (both P<0.05). The patients were followed up for (22.1±10.6) months without local recurrence and distant metastasis. Eighteen patients were evaluated for anal function: Kirwan classification was grade I for 6 cases, grade II for 7 cases, grade III for 4 cases, and grade IV for 1 case; Wexner incontinence score was 8.6±0.8; 14 cases had good defecation control. Conclusion: The clinical efficacy of ISR with Da Vinci robot in the treatment of low rectal cancer is satisfactory.

Abstract
Anorectal malignant melanoma is a very rare but aggressive cancer which carries poor prognosis. Surgical intervention is the main management but whether wide local excision or abdominoperineal resection has better survival benefit remains controversial. However, robotic-assisted restorative proctectomy with coloanal anastomosis with intersphincteric resection (ISR) has not been reported yet. Hence, we presented a case with anorectal malignant melanoma treated with robotic-assisted ISR with coloanal anastomosis. The patient has satisfied post-operative life quality, and no local recurrence was noted after 3-year follow-up.

Abstract
The anorectum is a complex region, whose anatomic structure is the basis and premise of intersphincteric resection (ISR) for low rectal cancer. With the development of pelvic surgery and minimally invasive surgery, the anatomic approaches, surgical planes, extent of excision and reconstruction strategies of ISR have been better understood. Surgeons can furthest preserve anal function as well as adhere to the principles of radical resection. However, the anatomy of the anorectum has not been fully understood. We hope further exploration of the anal canal anatomy, including the perirectal fascia, rectourethral muscle, anococcygeal ligament, hiatal ligament, levator ani muscle, internal and externals phincter, intersphincteric nerves, conjointed longitudinal muscle, intersphincteric spaces and the surgical approaches, by reviewing relevant literatures combined with the experiences of our clinical practice and applied anatomy, will help to improve the accuracy of the surgeries and increase the oncologic and functional outcomes of ISR.

Abstract
Background Simultaneous occurrence of colorectal malignancy with pelvic kidney has been considered a rare phenomenon. A review of the related literature revealed three previous reports of rectal cancer and pelvice kidney. Case presentation This case report describe the case of 40-year-old Asian man with complaints of bleeding and a feeling of discomfort in his anus. A colonoscopy revealed a raised large multilobulated mass in his rectum. Multiple biopsies of the lesion were done after detecting a tumor in his rectum 4 cm above the dentate line; a diagnosis of rectal adenocarcinoma was made by pathological examinations. Subsequent investigations, carried out by computed tomography (CT) scans, incidentally showed an ectopic pelvic kidney. Because of the progress of the rectal cancer, our patient was a candidate for neoadjuvant radiotherapy. Six weeks after radiotherapy, he underwent total mesorectal excision (TME) surgery maintaining the ectopic kidney after using a coloanal anastomosis for additional curative surgery. A very low anterior resection surgery was performed to maintain the ectopic kidney. Thereafter, adjuvant chemotherapy was performed. Conclusions Due to the proximity of the tumor to the pelvic viscera, especially the ectopic kidney, the probability of inadequate abscission of the lesion in surgery and radiotherapy, as well as complications and localized relapse were increased so that the kidney could be maintained. Carrying out careful pre-treatment examinations can result in maintaining an ectopic kidney and its daily conditioned function dependent on the status of the patient, including the proximity of the ectopic kidney to the tumor, anatomical position, and prior damage. The lesson learned from the present case is that radiotherapy and surgery are possible treatments in the presence of pelvic kidney and rectal cancer without incurring renal damage.

Abstract
Intersphincteric resection (ISR) is the ultimate sphincter-preserving procedure for low rectal cancer. A questionnaire about the standardization of ISR was given to 2125 patients who underwent curative ISR for low rectal cancer between 2005 and 2012 at 127 affiliated institutions of the Japanese Society for Cancer of the Colon and Rectum (JSCCR), and the results were compared with the results of a systematic review. The findings revealed that although mortality and morbidity were relatively low and the survival rate after ISR was good, the rates of local recurrence and postoperative fecal incontinence were relatively high. The radicality of ISR was compared with that of abdominoperineal resection and low anterior resection using the propensity score matching prognosis analysis of patients in the JSCCR nationwide registry. The local recurrence rate was significantly higher after ISR, and especially high in patients with T3 (invasion into the external anal sphincter) and T4 disease. These results provide evidence about the factors related to fecal incontinence after ISR. As measures for the standardization of ISR, it is important to reconfirm that ISR is not indicated for patients with cT3 and cT4 disease and those with poor preoperative defecatory function, based on the ISR indication criteria.

Abstract
PURPOSE Few studies have compared robotic and laparoscopic intersphincteric resection (ISR) in rectal cancer. Therefore, we performed a meta-analysis of recently published studies to compare perioperative outcomes of ISR for the treatment of low rectal cancer. METHODS We performed a systematic literature search of the Ovid-Medline, Ovid-EMBASE, and Cochrane Central Register of Controlled Trials databases for studies comparing robotic and laparoscopic ISR in patients with low rectal cancer. Demographic and clinical data were extracted from articles that met the inclusion and exclusion criteria. Perioperative outcomes of interest included the rate of diverting stoma, open conversion rate, operation time, estimated blood loss, length of hospital stay, time to first flatus, and time to initiate the postoperative diet. Oncological outcomes included the number of retrieved lymph nodes, distal resection margin, proximal resection margin, circumferential resection margin, 3-year overall survival, 3-year disease-free survival, and local recurrence. Postoperative complications included overall complications, a Dindo-Clavien classification ≥ III, and anastomotic leakage. All outcomes were compared between the two groups. RESULTS We included 5 retrospective cohort studies with a total of 510 patients undergoing 273 (53.5%) robotic ISR procedures and 237 (46.5%) laparoscopic ISR procedures. The robotic ISR group lower conversion rate, lower blood loss, and longer operation times than the laparoscopic group. We also noted that fewer lymph nodes were harvested in the robotic ISR group; however, this difference was not statistically significant. Other outcomes were similar between the two groups. CONCLUSIONS Robotic and laparoscopic ISR showed comparable perioperative outcomes, functional outcomes, and 3-year oncologic outcomes; however, robotic ISR was associated with a lower conversion rate and less blood loss despite longer operation times compared to laparoscopic ISR. These findings suggest that robotic ISR maybe a safe and effective technique for treating low rectal cancer in selected patients. The potential oncologic and functional benefits of robotic ISR should be evaluated in larger randomized controlled trials.

Abstract
Objective: To explore clinical features and prognosis factors of surgical complications after intersphincteric resection (ISR) for low rectal cancer following neoadjuvant chemoradiotherapy. Methods: The clinical data of 132 patients with low rectal cancer who underwent ISR following neoadjuvant chemoradiotherapy from September 2010 to June 2017 at Department of Colorectal Surgery, Sixth Affiliated Hospital, Sun Yat-sen University were retrospectively reviewed. There were 100 males and 32 females, with the age of (52.9±11.4) years and distance to anal verge of 3.9 cm. Records of perioperative complication (POC) within 30 days after surgery, anastomotic leakage (AL), and anastomotic stenosis (AS) were analyzed. POC was recorded according to the Clavien-Dindo classification. AL was graded by ISREC system and classified into the early AL within 30 days after surgery and delayed AL beyond 30 days. AS was defined as narrowing of the bowel lumen at the anastomosis that prevented passage through a colonoscope with a 12 mm diameter. According to the shape of narrowing, AS was recorded as the stenosis in situ or stenosis with long-segment bowel above. Univariate and multivariate analysis were used to identify risk factors of anastomotic complications. Results: Among the 132 patients, full-dose radiotherapy and diverting stoma were performed in 128 (97.0%) patients, respectively. In entire cohort, AL was found in 41 (31.1%) patients, including 32 patients with clinical leakage (24.2%). The median time for diagnosis of AL was 37 days (2 to 214 days) after surgery. There were 25 patients (18.9%) who were diagnosed with delayed AL beyond 30 days. Chronic presacral sinus formation was detected in 22 of 129 (17.1%) patients at 12 months from surgery. Among the 128 eligible patients, 36 (28.1%) were diagnosed as AS, including 24 (18.8%) patients with stenosis in situ and 12 (9.4%) patients with bowel stenosis above. After a median follow-up of 26 months, 7(5.3%) patients received permanent colostomy and the other 20(15.2%) patients retained a persistent ileostomy, owing to anastomotic complications. Results of multivariate analysis showed that radiation colitis was an independent prognosis factor of AL after ISR (OR=5.04, 95% CI: 2.05 to 12.43, P=0.000); male gender (OR=5.19, 95% CI: 1.24 to 21.75, P=0.024) and AL (OR=8.49, 95% CI: 3.32 to 21.70, P=0.000) were independent prognosis factors of AS after ISR. Conclusions: Surgical complications are common after ISR for low rectal cancer patients with neoadjuvant chemoradiotherapy. A high rate of AL is observed after long-term follow-up, which is associated with AS. Increasing awareness of anastomotic complications after ISR should be raised, especially for male patients with radiation colitis.

Abstract
AIM We have developed an imaging functional assessment of defecation after partial intersphincteric resection (ISR) by fecoflowgram obtained by defecography. PATIENTS AND METHODS Between January 2012 and December 2014, 6 patients with temporary ileostomy who underwent partial ISR for lower rectal cancer at our hospital were enrolled in this study. Defecography was performed 2 weeks after closure of the ileostomy. The defecation of all patients was evaluated by defecography and a fecoflowgram calculated from defecography. During the same period, the control group was comprised of 2 male and 2 female healthy volunteers. RESULTS The descent of the perineum and linearization of the anorectal angle was observed relative to normal defecation in the healthy volunteers. All barium was discharged by a single abdominal pressure within 5 s in the controls. In patients after partial ISR, all barium could not be discharged by a single abdominal pressure. The time course of pressure distribution after ISR was lower than that of healthy volunteers, which could not be evaluated by defecography. Defecation time in patients following ISR was longer than that of healthy volunteers. CONCLUSION Fecoflowgrams calculated from defecography seem to be useful for functional assessment of defecation after rectal resection.

Abstract
INTRODUCTION Despite the progress in the treatment of colorectal cancer, there is still no optimal strategy for tumours located adjacent to the anal sphincter. This study aims to evaluate oncological and functional results of surgery for rectal cancer in unfavourable locations in proximity to anal sphincters. MATERIALS AND METHODS Patients with rectal cancer, which was either initially infiltrating the anal sphincter or located in the close proximity of the sphincter, were included in the study. Patients were submitted to extralevator abdominoperineal resection (APR), intersphincteric resection, or transanal total mesorectal excision (TaTME). Primary outcomes were perioperative data: operative time, blood loss, complications, length of stay (LOS), and 30-day mortality. Secondary outcomes were pathological quality of the specimens and functional outcome 6 months after defunctioning ileostomy closure. RESULTS Among patients with cancer adjacent to the anal sphincter, 13 (25%) underwent APR, 14 (27%) patients were submitted to intersphincteric resection, and 25 (48%) patients were treated with the TaTME approach. Operative time was 240 (210-270 IQR) for APR, 212.5 (170-260 IQR) for intersphincteric resection, and 270 (240-330 IQR) for TaTME (p = 0.018). Perioperative morbidity was 31% for APR, 36% for intersphincteric resections, and 12% for the TaTME group (p = 0.181). Complete mesorectal excision was achieved in 92% of specimens in the TaTME group, 93% in intersphincteric resections, and 78% in the APR group (p = 0.72). Median circumferential resection margin in APR was 6 mm (4-7 IQR), in intersphincteric resections 7.5 mm (2.5-10 IQR), and in the TaTME group 4 mm (2.8-8 IQR). All patients after intersphincteric resections developed major low anterior resection syndrome (LARS). Four patients in the TaTME group developed minor LARS, and 21 had major LARS. CONCLUSION Sphincter-saving rectal resections are a feasible alternative to APR with good clinical, pathological, and oncological outcomes. Intersphincteric resections and TaTME seem to be equal in terms of clinicopathological results. The functional outcome is yet to be investigated. TRIAL REGISTRATION The study was retrospectively registered in Thai Clinical Trials Registry (23-07-2018, ID TCTR20180724001 ).

Abstract
The aim of this review is to evaluate the outcomes after an intersphincteric resection (ISR) for patients with low-lying rectal cancer. Reports published in the literature regarding surgical, oncological, and functional outcomes of an ISR were reviewed. The morbidity after an ISR was 7.7%–32%, and anastomotic leakage was the most common adverse event. Local recurrence rates ranged from 0% to 12%, 5-year overall survival rates ranged from 62% to 92%, and rates of major incontinence ranged from 0% to 25.8% after an ISR. An ISR is a safe procedure for sphincter-saving rectal surgery in patients with very low rectal cancer; it does not compromise the oncological outcomes of the resection and is a valuable alternative to an abdominoperineal resection. While the functional outcomes after an ISR were found to be acceptable, the long-term functional outcome and quality of life still require careful investigation. ISRs have been performed with surgical and oncologic safety on patients with low-lying rectal cancer. However, patients must be selected very carefully for an ISR, considering the associated functional derangement and the limited extent of the resection.

Abstract
PURPOSE To compare the time-course change in the postoperative anorectal function between laparoscopic intersphincteric resection (ISR) and low anterior resection (LAR). METHODS This is a single-institution observational study. We evaluated the time-course change in the anorectal function using functional questionnaires before and at 6, 12, and 24 months after laparoscopic ISR or LAR. RESULTS Sixty-two patients answered the functional questionnaires (28 in the ISR group and 34 in the LAR group). In the ISR group, the Wexner scores at 6, 12, and 24 months postoperatively were significantly higher than preoperatively. Importantly, the Wexner score at 24 months postoperatively was significantly lower than that at 6 months postoperatively. The low GIFO scores at 6 and 12 months postoperatively tended to be recovered to some extent at 24 months postoperatively. In the LAR group, Wexner score at 6 months postoperatively was significantly higher than that preoperatively. Notably, the Wexner score at 12 months postoperatively was recovered to almost the same as that preoperatively. The GIFO scores at 12 months postoperatively were mostly recovered to the same levels as those preoperatively. CONCLUSIONS Laparoscopic ISR exhibits different time-course changes in the anorectal function from laparoscopic LAR.

Abstract
Objective This study was performed to evaluate the 1-year survival rate and functional outcomes of 20 patients who underwent intersphincteric resection (ISR) for low rectal cancer. Methods Twenty patients who underwent ISR for low rectal cancer were followed up for 1 year. Complications, functional outcomes objectified by the Wexner score, and oncological outcomes were assessed. Results The short-term survival rate was 100%. The median Wexner score was ≤10 in all patients at 12 months after surgery. Signs of local recurrence were absent, and antigen levels remained within the reference ranges 1 year postoperatively. Conclusions ISR is a feasible alternative in highly selected patients who primarily refuse a colostomy bag and present with type II or III tumors. In the present study, patient-reported continence was satisfactory, and the absence of a colostomy bag increased patients’ quality of life. The oncological outcomes were satisfactory at 1 year postoperatively.

Abstract
Adequate oncological outcomes have been demonstrated with rectal resection and handsewn coloanal anastomosis (CAA) in tumours in close proximity to the internal anal sphincter. Our aim was to assess functional differences between handsewn CAA and ultralow stapled anastomosis. Participants were identified from a single-surgeon series. Included participants underwent anorectal physiology testing of anal sphincter function, in addition to completion of several questionnaires: Wexner Incontinence Score (WIS); Birmingham Bowel, Bladder and Urinary Symptom Questionnaire (BBUSQ); Low Anterior Resection Syndrome (LARS) Score; SF36. Non-parametric data compared using the Mann–Whitney U test. 20 participants were included; 11 stapled and 9 handsewn. Mean follow-up was 2.95 ± 1.97 years. The mean LARS score was 21.9 ± 1.97 years in the stapled group versus 29.4 ± 9.57 in the handsewn group (p = 0.133). The Wexner incontinence score was significantly higher in the handsewn group (p = 0.0076), with a mean score of 4.6 ± 3.69 versus 10.9 ± 4.76. The incontinence domain of the BBUSQ was also significantly worse in patients with a handsewn anastomosis (p = 0.001). With the exception of general health (p = 0.035) and social functioning (p = 0.035), which were worse in the handsewn groups, the other six domains of the SF-36 showed no statistical difference between groups. Anorectal physiology scores were not significantly different. Handsewn CAA anastomosis is known to be safe and oncologically feasible. Patient selection should be vigorous, with preoperative counseling regarding the likelihood of incontinence to manage patients’ expectations and promote comparable quality of life in the long-term.

Abstract
AIM The aim of this study was to compare the short-term and mid-term effects of laparoscopic intersphincteric resection with the conventional open approach for patients with low rectal cancer through a meta-analysis. METHODS The PubMed, EMBASE, Cochrane, and Ovid databases were searched for eligible studies until March 2017. Operation time, blood loss, circumferential resection margin-positive rate, distal margin length, number of resected lymph nodes, diverting stoma rate, postoperative overall morbidity, anastomotic leakage, and hospital stay were the main short-term effect endpoints. We also examined disease-free survival, overall survival, local recurrence, and post-operational anal function as secondary outcomes to evaluate the mid-term effects of laparoscopic surgery. RESULTS Five studies involving 620 patients were included in the analyses. Compared with the open approach, the laparoscopic ISR had less blood loss (weighted mean difference [WMD] = - 214.65 ml, 95% CI [- 370.44, - 196.13], p < 0.01), less postoperative overall morbidity (OR = 0.58, 95% CI [0.40, 0.86], p < 0.01), and shorter duration of hospital stay (WMD = - 5.87 days, 95% CI [- 11.35, - 0.40], p < 0.05); however, the operation time was significantly longer in the laparoscopic group (WMD = 47.34 min, 95% CI [4.10, 90.58], p < 0.05). No other significant differences were observed. CONCLUSION Laparoscopic ISR for low rectal cancer offers fewer complications and faster recovery, with similar operation quality and mid-term oncological results than the conventional approach. Although this technique is comparatively more complex than the conventional approach and requires practice, laparoscopic ISR shows great potential as a surgical option and deserves further clinical study.

Abstract
Surgery for low rectal cancer often involves a permanent stoma. Intersphincteric resection (ISR) with colo-anal anastomosis is a valuable sphincter sparing surgical procedure that avoids the need for permanent stoma in patients with low rectal cancer. The aim of this study was to analyze the long-term functional and oncological outcomes following ISR. This was a retrospective analysis of patients with low rectal cancer who underwent ISR with colo-anal anastomosis in our institution between 2007 and 2015. All patients had a diversion stoma. Bowel function outcomes were assessed prospectively using Wexner incontinence score, low anterior resection syndrome score (LARS), and the Cancer Institute Quality of Life (QoL) questionnaire. The histological reports were reviewed to assess the oncological adequacy of the surgery. Patterns of recurrence and survival were analyzed in this group of patients. Thirty-three patients who underwent an ISR were eligible for this study. Laparoscopic resection was performed in five patients. All the patients received neoadjuvant chemoradiation except the two who received short course radiation and one who did not receive any neoadjuvant treatment. The median distance from the anal verge to the distal edge of the tumor was 3 cm (range 1.5-5 cm). Distal resection margins and circumferential resection margins were negative in all the patients. The 30-day post-operative mortality rate was 3.03%. In 20 patients with a median follow-up of 48 months, the 3-year overall survival was 95%. One patient had recurrence in the para-aortic nodes. No patient had a local recurrence. Bowel function was assessed in 18 patients who had a minimum stoma free period of 1 year. After a median of 43 months following stoma closure, the median Wexner score was 3.56 (range 0-19), median LARS score was 4.78 (range 0-33), and the mean Cancer Institute QoL score was 151.56 ± 15.741. The QoL was average to very high with an overall acceptable quality of life. In this study, ISR was associated with acceptable long-term functional and oncological outcomes. It can be considered as a safe alternative to a permanent stoma in selected patients with low rectal cancer.

Abstract
Anal function is one of the most important parameters for evaluating the efficacy of intersphincteric resection (ISR) for the treatment of ultralow rectal cancer (< 1 cm from the anal sphincter). Although there have been no results hitherto from randomized controlled trials to verify the clinical benefits of the ultimate sphincter-sparing technique, increasing evidence demonstrates that ISR significantly decreases the rate of permanent stoma and patients could acquire satisfied functional results after surgery. This review discusses the short-term and long-term functional outcomes, risk factors for anal incontinence, and surgical method and approach of ISR.

Abstract
AIM To assess the efficacy of a modified approach with transanal total mesorectal excision (taTME) using simple customized instruments in male patients with low rectal cancer.
METHODS A total of 115 male patients with low rectal cancer from December 2006 to August 2015 were retrospectively studied. All patients had a bulky tumor (tumor diameter ≥ 40 mm). Forty-one patients (group A) underwent a classical approach of transabdominal total mesorectal excision (TME) and transanal intersphincteric resection (ISR), and the other 74 patients (group B) underwent a modified approach with transabdominal TME, transanal ISR, and taTME. Some simple instruments including modified retractors and an anal dilator with a papilionaceous fixture were used to perform taTME. The operative time, quality of mesorectal excision, circumferential resection margin, local recurrence, and postoperative survival were evaluated.
RESULTS All 115 patients had successful sphincter preservation. The operative time in group B (240 min, range: 160-330 min) was significantly shorter than that in group A (280 min, range: 200-360 min; P = 0.000). Compared with group A, more complete distal mesorectum and total mesorectum were achieved in group B (100% vs 75.6%, P = 0.000; 90.5% vs 70.7%, P = 0.008, respectively). After 46.1 ± 25.6 mo follow-up, group B had a lower local recurrence rate and higher disease-free survival rate compared with group A, but these differences were not statistically significant (5.4% vs 14.6%, P = 0.093; 79.5% vs 65.1%, P = 0.130).
CONCLUSION Retrograde taTME with simple customized instruments can achieve high-quality TME, and it might be an effective and economical alternative for male patients with bulky tumors.

Abstract
Background Anastomotic leakage (AL) is one of the most dreadful postoperative complications because it can result in increased morbidity and mortality as well as poorer long-term prognosis. Although most studies of AL limited their investigation time to a period of 30 days postoperatively, only a few studies have shown that AL can occur after that period. Here, we report four patients of rectal cancer with delayed AL following laparoscopic intersphincteric resection (ISR) and conduct a literature review on delayed AL. Case presentation Case 1 was a 67-year-old male who underwent laparoscopic partial ISR in July 2009. Although the patient was asymptomatic, an anastomotic-urethral fistula was observed 57 months after ISR. Case 2 was a 44-year-old female who underwent laparoscopic partial ISR in July 2008. She presented with discharge of gas and feces from her vagina, and an anastomotic-vaginal fistula was observed 14 months after ISR. Case 3 was a 74-year-old man who underwent laparoscopic partial ISR in August 2007. He presented with pneumaturia and fecaluria, and an anastomotic-urethral fistula was observed 4 months after ISR. Case 4 was a 68-year-old woman who underwent laparoscopic subtotal ISR for rectal cancer in February 2013 and partial hepatic resection for liver metastases in March 2013. She presented with anal pain and purulent perineal discharge, and an anastomotic-perineal fistula was observed 9 months after ISR. All four cases presented with fistula formation and required reoperation (establishment of a diverting ileostomy). Conclusions Since delayed AL is not a rare postoperative complication, surgeons need to provide long-term follow-up and remain alert to the possible development of delayed AL.

Abstract
PURPOSE Few investigations of robot-assisted intersphincteric resection (ISR) are presently available to support this procedure as a safe and efficient procedure. We aimed to evaluate the utility of robot-assisted ISR by comparison between ISR and abdominoperineal resection (APR) using both robot-assisted and open approaches. METHODS The 558 patients with lower rectal cancer (LRC) who underwent curative operation was enrolled between July 2010 and June 2015 to perform either by robot-assisted (ISR vs. APR = 310 vs. 34) or open approaches (144 vs. 70). Perioperative and functional outcomes including urogenital and anorectal dysfunctions were measured. Recurrence and survival were examined in 216 patients in which >3 years had elapsed after the operation. RESULTS The robot-assisted approach was the most significant parameter to determine ISR achievement among potent parameters (OR = 3.467, 95% CI = 2.095-5.738, p < 0.001). Early surgical complications occurred more frequently in the open ISR group (16 vs. 7.7%, p = 0.01). The voiding and male sexual dysfunctions were significantly more frequent in the open ISR (p < 0.05). The fecal incontinence and lifestyle alteration score was greater in the open ISR than in the robot-assisted ISR at 12 and 24 months, respectively (p < 0.05). However, the 3-year cumulative rates of local recurrence and survival did not differ between the two groups. CONCLUSIONS The current procedure of robot-assisted ISR replaced a significant portion of APR to achieve successful SSO via mostly transabdominal approach and double-stapled anastomosis. The robot-assisted ISR with minimal invasiveness might be a help to reduce anorectal and urogenital dysfunctions.

Abstract
The study aims to compare open intersphincteric resection (OISR) with laparoscopic intersphincteric resection (LISR) in terms of short-term oncological and clinical outcomes. This is a retrospective review of a prospectively maintained database including all the patients of rectal cancer who underwent intersphincteric resection (ISR) at Tata Memorial Centre between 1st July 2013 and 30th November 2015. Short-term oncological parameters evaluated included circumferential resection margin involvement (CRM), distal resection margin involvement, and number of nodes harvested. Perioperative outcomes included blood loss, length of hospital stay and 30-day postoperative morbidity and mortality. Chi-square test was used to compare the results between the two groups. Thirty nine cases of OISR and 34 cases of LISR were included in the study. Median BMI was higher in LISR group; otherwise, the two groups were comparable in all aspects. There were no conversions in LISR group. CRM involvement was seen in four patients (10%) in the conventional group compared to none in the LISR group. Median hospital stay was comparable between the two groups. Laparoscopic ISR is safe and can be performed with low conversion rate in selected group of patients.

Abstract
AIM One of the most troublesome complications of anal preserving surgery is anal sphincter dysfunction. The aim of this study was to evaluate functional recovery after implantation of adipose-derived stem cell (ADSC) sheets, novel biotechnology, for an anal sphincter resection animal model. METHODS Eighteen female Sprague-Dawley rats underwent removal of the nearest half of the internal and external anal sphincter muscle. Nine rats received transplantation with ADSC sheets to the resected area while the remaining rats received no transplantation. The rats were evaluated for the anal function by measuring their resting pressure before surgery and on postoperative days 1, 7, 14, 28, and 56. In addition, the rats were examined for the presence of smooth muscle and also to determine its origin. RESULTS The improvement of the anal pressure was significantly greater in the ADSC sheet transplantation group compared with the control group. Histologically, at the vicinity of the remaining smooth muscle, reproduction of smooth muscle was detected. Using in fluorescence in situ hybridization, the cells were shown to be from the recipient. CONCLUSION Regenerative therapy using ADSC sheet has the potential to recover anal sphincter dysfunction due to anorectal surgery.

Abstract
PURPOSE Intersphincteric resection (ISR) is an alternative to abdominoperineal resection (APR) for a selected subset of patients with low rectal cancer, combining equivalent oncological outcome and sphincter preservation. However, functional results are heterogeneous and often imperfect. The aim of the present investigation was to determine the long-term functional results and quality of life after ISR. METHODS One hundred forty-three consecutive patients who underwent surgery for low rectal cancer were analysed. Sixty patients received ISR and 83 patients APR, respectively. Kaplan-Meier estimate was used to analyse patients' survival. The EORTC QLQ-C30, -C29 and the Wexner score were used to determine functional outcome and quality of life. RESULTS ISR and APR were both associated with comparable morbidity and no mortality. Patients' disease- and recurrence-free survival after ISR and APR were similar (p = 0.2872 and p = 0.4635). Closure of ileostomy was performed in 73% of all patients after ISR. Long-term outcome showed a rate of incontinence (Wexner score ≥10) in 66% of the patients. Despite this, patients' quality of life was significantly better after ISR compared to APR in terms of abdominal complaints and psycho-emotional functioning. CONCLUSIONS ISR is technically feasible with acceptable postoperative morbidity rates. Functional results following ISR are compromised by incontinence as the most important complication. However, long-term quality of life is superior to APR, which should be considered when selecting patients for ISR.
