AbstractAbstract PDF
Purpose
Prehabilitation (PH) is purported to improve patients’ preoperative functional status. This systematic review and meta-analysis sought to compare short-term postoperative outcomes between patients who underwent a protocolized PH program and the existing standard of care among colorectal cancer patients awaiting surgery.
Methods
A search in MEDLINE/PubMed, the Cochrane Library, Embase, Scopus, and CINAHL was conducted to identify relevant articles. Repetitive and exhaustive combinations of MeSH search terms (“prehabilitation,” “colorectal cancer,” “colon cancer,” and “rectal cancer”) were used to identify randomized and nonrandomized studies comparing PH versus standard of care for colorectal cancer patients awaiting surgery. The primary outcomes included postoperative morbidity, length of hospital stay, and readmission rates.
Results
Seven studies including 1,042 colorectal cancer patients (PH, 382) were included. No significant differences were found in intraoperative outcomes. The postoperative complication rates were comparable between groups (Clavien-Dindo grades I and II: risk ratio, 0.82; 95% confidence interval, 0.62–1.07; P=0.15; Clavien-Dindo grades ≥III: risk ratio, 1.02; 95% confidence interval, 0.72–1.44; P=0.92). There were also no significant differences in length of hospital stay (P=0.21) or the risk of 30-day readmission (P=0.68).
Conclusion
Although PH does not appear to improve short-term postoperative outcomes following colorectal cancer surgery, the quality of evidence is impaired by the limited trials and heterogeneity. Thus, further large-scale trials are warranted to draw definitive conclusions and establish the long-term effects of PH.

AbstractAbstract PDF
Purpose
We compared the incidence of venous thromboembolism (VTE) among Asian populations with localized colorectal cancer undergoing curative resection with and without the use of pharmacological thromboprophylaxis (PTP).
Methods
A comprehensive literature search was undertaken to identify relevant studies published from January 1, 1980 to February 28, 2022. The inclusion criteria were patients who underwent primary tumor resection for localized nonmetastatic colorectal cancer; an Asian population or studies conducted in an Asian country; randomized controlled trials, case-control studies, or cohort studies; and the incidence of symptomatic VTE, deep vein thrombosis, and/or pulmonary embolism as the primary study outcomes. Data were pooled using a random-effects model. This study was registered in PROSPERO on October 11, 2020 (No. CRD42020206793).
Results
Seven studies (2 randomized controlled trials and 5 observational cohort studies) were included, encompassing 5,302 patients. The overall incidence of VTE was 1.4%. The use of PTP did not significantly reduce overall VTE incidence: 1.1% (95% confidence interval [CI], 0%–3.1%) versus 1.9% (95% CI, 0.3%–4.4%; P = 0.55). Similarly, PTP was not associated with significantly lower rates of symptomatic VTE, proximal deep vein thrombosis, or pulmonary embolism.
Conclusion
The benefit of PTP in reducing VTE incidence among Asian patients undergoing curative resection for localized colorectal cancer has not been clearly established. The decision to administer PTP should be evaluated on a case-bycase basis and with consideration of associated bleeding risks.

Purpose
As introduced, multimodal pain management bundle for ileostomy reversal may be considered to reduce postoperative pain and hospital stay. The aim of this study was to evaluate clinical efficacy of perioperative multimodal pain bundle for ileostomy.
Methods
Medical records of patients who underwent ileostomy reversal after rectal cancer surgery from April 2017 to March 2020 were analyzed. Sixty-seven patients received multimodal pain bundle protocol with ileostomy reversal (group A) and 41 patients underwent closure of ileostomy with conventional pain management (group B).
Results
Baseline characteristics, including age, sex, body mass index, American Society of Anesthesiologists classification, diabetes mellitus, and smoking history, were not significantly different between the groups. The pain score on postoperative day 1 was significant lower in group A (visual analog scale, 2.6 ± 1.3 vs. 3.2 ± 1.2; P = 0.013). Overall consumption of opioid in group A was significant less than group B (9.7 ± 9.5 vs. 21.2 ± 8.8, P < 0.001). Hospital stay was significantly shorter in group A (2.3 ± 1.5 days vs. 4.1 ± 1.5 days, P < 0.001). There were no significant differences between the groups in postoperative complication rate.
Conclusion
Multimodal pain protocol for ileostomy reversal could reduce postoperative pain, usage of opioid and hospital stay compared to conventional pain management.

AbstractAbstract PDF
Purpose
Fistulotomy is considered the most effective treatment for anal fistula; however, it carries a risk of incontinence. Sphincteroplasty in the setting of fistulotomy is not standard practice due to concerns regarding healing and potential infectious complications. We aimed to compare the outcomes of patients who underwent fistulotomy with primary sphincteroplasty to those who did not undergo repair.
Methods
This was a retrospective review of consecutive patients who underwent fistulotomy for cryptoglandular anal fistula. All operations were performed by one colorectal surgeon. Sphincteroplasty was performed for patients perceived to be at higher risk for continence disturbance. The main outcome measures were the healing rate and postoperative septic complications.
Results
In total, 152 patients were analyzed. Group A (fistulotomy with sphincteroplasty) consisted of 45 patients and group B (fistulotomy alone) included 107 patients. Both groups were similar in age (P=0.16) and sex (P=0.20). Group A had higher proportions of multiple fistulas (26.7% vs. 6.5%, P<0.01) and complex fistulas (mid to high transsphincteric, 37.8% vs. 10.3%; P<0.01) than group B. The median follow-up time was 8 weeks. The overall healing rate was similar in both groups (93.3% vs. 90.6%, P=0.76). No significant difference between the 2 groups was noted in septic complications (6.7% vs. 3.7%, P=0.42).
Conclusion
Fistulotomy with primary sphincter repair demonstrated a comparable healing rate to fistulotomy alone, without an increased risk of postoperative septic complications. Further prospective randomized studies are needed to confirm these findings and to explore the functional outcomes of patients who undergo sphincteroplasty.

Graphical AbstractGraphical Abstract AbstractAbstract PDF
Purpose
Preoperative colonoscopic (POC) localization is recommended for patients scheduled for elective laparoscopic colectomy for early colon cancer. Among the various localization method, POC tattooing localization has been widely used. Several dyes have been used for tattooing, but dye has disadvantages, including foreign body reactions. For this reason, we have used autologous blood tattooing for POC localization. This study aimed to evaluate the safety and efficacy of the autologous blood tattooing method.
Methods
This study included patients who required POC localization of the colonic neoplasm among the patients who were scheduled for elective colon resection. The indication for localization was early colon cancer (clinically T1 or T2) or colonic neoplasms that could not be resected endoscopically. POC autologous blood tattooing was performed after saline injection, and 2 hemoclips were applied.
Results
A total of 45 patients who underwent autologous blood tattooing and laparoscopic colectomy were included in this study. All POC localization sites were visible in the laparoscopic view. POC localization sites showed almost perfect agreement with intraoperative surgical findings. There were no complications like bowel perforation, peritonitis, hemoperitoneum, and mesenteric hematoma.
Conclusion
Autologous blood is a safe and effective agent for localizing materials that can replace previous dyes. However, a large prospective case-control study is required for the routine application of this procedure in early colon cancer or colonic neoplasms.

AbstractAbstract PDF
Purpose
This study assessed the long-term outcomes and quality of life in patients who underwent sacral neuromodulation (SNM) due to low anterior resection syndrome (LARS).
Methods
This single-center retrospective study, conducted from 2005 to 2021, included 30 patients (21 men; median age, 70 years) who had undergone total mesorectal excision with stoma closure and had no recurrence at inclusion. All patients were diagnosed with LARS refractory to conservative treatment. We evaluated clinical and quality-of-life outcomes after SNM through a stool diary, Wexner score, LARS score, the Fecal Incontinence Quality of Life (FIQL) questionnaire, and EuroQol-5D (EQ-5D) questionnaire.
Results
Peripheral nerve stimulation was successful in all but one patient. Of the 29 patients who underwent percutaneous nerve evaluation, 17 (58.62%) responded well to SNM and received permanent implants. The median follow-up period was 48 months (range, 18–153 months). The number of days per week with fecal incontinence episodes decreased from a median of 7 (range, 2–7) to 0.38 (range, 0–1). The median number of bowel movements recorded in patient diaries fell from 5 (range, 4–12) to 2 (range, 1–6). The median Wexner score decreased from 18 (range, 13–20) to 6 (range, 0–16), while the LARS score declined from 38.5 (range, 37–42) to 19 (range, 4–28). The FIQL and EQ-5D questionnaires demonstrated enhanced quality of life.
Conclusion
SNM may benefit patients diagnosed with LARS following rectal cancer surgery when conservative options have failed, and the treatment outcomes may possess long-term sustainability.

AbstractAbstract PDF
Purpose
This study aimed to investigate preoperative predictors of lymphovascular invasion (LVI), which is a poor prognostic factor usually detected postoperatively in patients with colorectal cancer.
Methods
Results for all patients operated on for colorectal cancer between January 1, 2006, and December 31, 2021, were retrospectively analyzed. Potential preoperative factors and postoperative pathology results were recorded. The patients were categorized as those with LVI and those without LVI. Potential factors that may be associated with LVI were compared between the 2 groups.
Results
The study included 335 patients. The incidence of LVI was 3.11 times higher in patients with ascending colon tumors (odds ratio [OR], 3.11; 95% confidence interval [CI], 1.34–7.23; P=0.008) and 4.28 times higher in those with metastatic tumors (OR, 4.28; 95% CI, 2.18–8.39; P<0.001). Diabetes mellitus was inversely related to LVI in colorectal cancer patients; specifically, LVI was 56% less common in colorectal cancer patients with diabetes mellitus, irrespective of its duration (OR, 0.44; 95% CI, 0.25–0.76; P<0.001).
Conclusion
The presence of preoperative LVI in colorectal cancer patients is difficult to predict. In particular, the effect of the effect of factors such as chronic disease accompanied by microvascular pathologies on LVI is still unclear. Advances in the neoadjuvant treatment of colorectal cancer patients, who are becoming more widespread every day, will encourage the investigation of different methods of preoperatively predicting LVI as a poor prognostic factor in these patients.

AbstractAbstract PDF
Purpose
Although partial mesorectal excision (PME) and total mesorectal excision (TME) is primarily indicated for the upper and lower rectal cancer, respectively, few studies have evaluated whether PME or TME is more optimal for middle rectal cancer.
Methods
This study included 671 patients with middle and upper rectal cancer who underwent robot-assisted PME or TME. The 2 groups were optimized by propensity score matching of sex, age, clinical stage, tumor location, and neoadjuvant treatment.
Results
Complete mesorectal excision was achieved in 617 of 671 patients (92.0%), without showing a difference between the PME and TME groups. Local recurrence rate (5.3% vs. 4.3%, P>0.999) and systemic recurrence rate (8.5% vs. 16.0%, P=0.181) also did not differ between the 2 groups, in patients with middle and upper rectal cancer. The 5-year disease-free survival (81.4% vs. 74.0%, P=0.537) and overall survival (88.0% vs. 81.1%, P=0.847) also did not differ between the PME and TME groups, confined to middle rectal cancer. Moreover, 5-year recurrence and survival rates were not affected by distal resection margins of 2 cm (P=0.112) to 4 cm (P>0.999), regardless of pathological stages. Postoperative complication rate was higher in the TME than in the PME group (21.4% vs. 14.5%, P=0.027). Incontinence was independently associated with TME (odds ratio [OR], 2.009; 95% confidence interval, 1.015–3.975; P=0.045), along with older age (OR, 4.366, P<0.001) and prolonged operation time (OR, 2.196; P=0.500).
Conclusion
PME can be primarily recommended for patients with middle rectal cancer with lower margin of >5 cm from the anal verge.

AbstractAbstract PDF
Purpose
Stenting is a useful treatment option for malignant colonic obstruction, but its role remains unclear. This study was designed to establish how stents have been used in Queensland, Australia, and to review outcomes.
Methods
Patients diagnosed with colorectal cancer in Queensland from January 1, 2008, to December 31, 2014, who underwent colonic stent insertion were reviewed. Primary outcomes of 5-year survival, 30-day mortality, and overall length of survival were calculated. The secondary outcomes included patient and tumor factors, and stoma rates.
Results
In total, 319 patients were included, and distant metastases were identified in 183 patients (57.4%). The 30-day mortality rate was 6.6% (n=21), and the 5-year survival was 11.9% (n=38). Median survival was 11 months (interquartile range, 4–27 months). A further operation (hazard ratio [HR], 0.19; P<0.001) and chemotherapy and/or radiotherapy (HR, 0.718; P=0.046) reduced the risk of 5-year mortality. The presence of distant metastases (HR, 2.052; P<0.001) and a comorbidity score of 3 or more (HR, 1.572; P=0.20) increased mortality. Surgery was associated with a reduced risk of mortality even in patients with metastatic disease (HR, 0.14; P<0.001). Twenty-two patients (6.9%) ended the study period with a stoma.
Conclusion
Colorectal stenting was used in Queensland in several diverse scenarios, in both localized and metastatic disease. Surgery had a survival advantage, even in patients with metastatic disease. There was no survival difference according to whether patients were socioeconomically disadvantaged, diagnosed in a major city or not, or treated at private or public hospitals. Stenting proved a valid treatment option with low stoma rates.

AbstractAbstract PDFSupplementary Material
Complete mesocolic excision and central vascular ligation with D3 lymphadenectomy are important surgical principles for improving oncological outcomes in colon cancer. The cranial-first approach is a colonic mobilization–first approach to radical right hemicolectomy, which has several advantages, including early feasibility assessment, safe dissection from surrounding organs, preestablished inferior margin of lymph node dissection, and revelation of the tangible anatomy of the tributaries of the gastrocolic trunk. This video demonstrates the cranial-first approach to radical right hemicolectomy in a 66-year-old man with locally advanced cecal cancer.
