Abstract PDF

Purpose
Current acceptance of the watch-and-wait (W&W) approach by surgeons in Asia-Pacific countries is unknown. An international survey was performed to determine status of the W&W approach on behalf of the Asia-Pacific Federation of Coloproctology (APFCP).
Methods
Surgeons in the APFCP completed an Institutional Review Board-approved anonymous e-survey and/or printed letters (for China) containing 19 questions regarding nonsurgical close observation in patients who achieved clinical complete response (cCR) to neoadjuvant chemoradiotherapy (nCRT).
Results
Of the 417 responses, 80.8% (n = 337) supported the W&W approach and 65.5% (n = 273) treated patients who achieved cCR after nCRT. Importantly, 78% of participants (n = 326) preferred a selective W&W approach in patients with old age and medical comorbidities who achieved cCR. In regard to restaging methods after nCRT, the majority of respondents based their decision to use W&W on a combination of magnetic resonance imaging results (94.5%, n = 394) with other test results. For interval between nCRT completion and tumor response assessment, most participants used 8 weeks (n = 154, 36.9%), followed by 6 weeks (n = 127, 30.5%) and 4 weeks (n = 102, 24.5%). In response to the question of how often responders followed-up after W&W, the predominant period was every 3 months (209 participants, 50.1%) followed by every 2 months (75 participants, 18.0%). If local regrowth was found during follow-up, most participants (79.9%, n = 333) recommended radical surgery as an initial management.
Conclusion
The W&W approach is supported by 80% of Asia-Pacific surgeons and is practiced at 65%, although heterogeneous hospital or society protocols are also observed. These results inform oncologists of future clinical study participation.

Abstract PDF

This article aimed to summarize the current status of colorectal cancer (CRC) in Thailand. In brief, CRC is the third most common cancer and accounts for 11% of the cancer burden in Thailand. It is the only malignancy with an increased incidence in both sexes in Thailand. Over 10,000 new CRC cases occur annually, and about 40% are rectal cancer. Due to the lack of CRC screening and public awareness, nonmetastatic cancer accounts only for 60%–70% of overall cases. The demand for general or colorectal surgeons outmatches the supply at a ratio of 1 general surgeon to 35,000 individuals. There are about 70 board-certified colorectal surgeons serving Thailand’s population of nearly 70 million. As a result, >25% of cancer patients wait more than 1 month before surgery. Regarding training for colorectal surgery, there are 3 major institutes in Bangkok providing a 2-year fellowship program. Cadaveric workshops are an important part of training – especially in laparoscopy for CRC. Recently, a population-based CRC screening program was launched using a fecal immunochemical test. The Ministry of Public Health of Thailand has established additional platforms for laparoscopy to support the potential detection of early CRC following implementation of this nationwide screening program.

Abstract PDF

Purpose
Patients who undergo radical surgery for rectal cancer often experience low anterior resection syndrome (LARS). Symptoms of this syndrome include frequent bowel movements, gas incontinence, fecal incontinence, fragmentation, and urgency. The aim of this study was to investigate the convergent validity, discriminative validity, and reliability of the Korean version of the LARS score questionnaire.
Methods
The English LARS score questionnaire was translated into Korean using the forward-and-back translation method. A total of 146 patients who underwent radical surgery for rectal cancer answered the Korean version of the LARS score questionnaire including an anchor question assessing the impact of bowel function. Participants answered the questionnaire once more after 2 weeks.
Results
The Korean LARS score questionnaire showed high convergent validity in terms of high correlation between the LARS score and quality of life (perfect fit 55.5% vs. moderate fit 37.6% vs. no fit 6.8%, respectively; P < 0.001). The LARS score also showed good discriminative validity between groups of patients differing by sex (29 for males vs. 25 for females; P = 0.014), tumor level (29 for ≤8 cm vs. 24 for >8 cm; P = 0.021), and radiotherapy (32 for yes vs. 24 for no; P = 0.001). The LARS score also demonstrated high reliability at test-retest with no difference between scores at the first and second tests (intraclass correlation coefficient: Q1 = 0.932; Q2 = 0.909, Q3 = 0.944, Q4 = 0.931, and Q5 = 0.942; P < 0.001, respectively).
Conclusion
The Korean version of the LARS score questionnaire has proven to be a valid and reliable tool for measuring LARS in Korean patients with rectal cancer.

Abstract PDF

Purpose
Propiverine hydrochloride (PH) is widely used for the treatment of urinary incontinence (UI) due to bladder overactivity. Moreover, the comorbidity of UI with fecal incontinence (FI) is known to be due to the relationship of both to nervous system disorders and dysfunction or weakening of the pelvic floor muscles. The aim of this single-arm prospective study was to evaluate the therapeutic value of PH for FI.Methods: Patients (n = 24) who were diagnosed as having both FI and UI from April 2015 to November 2016 were included in the study and administered a dosage of 10–20 mg PH every day for 1 month. The primary endpoint was to create a reduction in the frequency of FI per week. An evaluation criterion of ≥50% reduction in frequency was determined as effective. The percentage of the patients who achieved the ≥50% endpoint (responders) was also calculated.Results: The frequency of FI per week was 6.0 ± 8.2 (0.25–30) at baseline and reduced to 1.6 ± 2.1 (0–7) at the posttherapeutic state (P = 0.005). A reduction of ≥50% was seen in 14 of the patients (58.3%).Conclusion: PH reduced the frequency of FI in patients with both FI and UI. This study introduces a possible therapeutic option for the pharmacological treatment of FI.

Abstract PDF

Purpose
The purpose of this study was to demonstrate the feasibility and safety of laparoscopic-assisted anterior resection (LAAR) for colorectal cancer in a local Asian population.
Methods
This is a retrospective review of all patients with colorectal cancer operated from November 2017 to October 2018. Main variables of interest were demography, type and surgery, length of stay (LOS), and the involvement of proximal and distal doughnut. Postoperative complications were analysed using chi-square or Fisher exact and Mann-Whitney tests.
Results
There were 23 patients with a mean age of 62.5 ± 12.2 years. The mean time from diagnosis to surgery was 97.1 ± 154.84 days. There were 12 patients in the LAAR group and 11 in the open anterior resection (OAR) group. Duration of surgery was shorter in OAR (129.58 ± 51.38 minutes) compared to LAAR (147.91 ± 39.37 minutes). Mean LOS was shorter in the LAAR group with 5±1.5 days compared to the OAR group of 7.42 ± 4.25 days. However, there was no significant P-value for both duration of surgery (P = 0.322) or LOS (P = 0.87). A total of 3 complications were recorded after OAR and 2 after LAAR. Both groups had clear proximal and distal margins with 16 (12–18.5) harvested lymph nodes in LAAR and 18 (16–22) in OAR, which were equal (P = 0.155).
Conclusion
This study reports a shorter LOS in the minimally invasive group of 2 days with similar oncologic resection outcomes. This shows that LAAR is feasible in Malaysia and has potential outcome benefits.

Purpose
Pertaining to the Colorectal Surgery Society of Australia and New Zealand (CSSANZ) Executive and Research Support Committee, this study aimed to assess the usefulness and outcomes of surveys sent out by the society to its members.
Methods
From 2009 to 2017, CSSANZ members received 38 surveys, most of which were distributed from within the society, and a few of which originated from other affiliated groups. Surveys were categorised by type, topics, times required for completion, delivery method, response rates, and advancement to publication.
Results
Of 38 surveys, 20 (53%) were published and 18 remain unpublished. Four surveys were distributed annually on average, with 2.2 published annually on average, with a mean impact factor of 2.41 ± 1.55. Mean time to publication was 31 ± 17 months. Surveys contributed to 13 publications (34%). The most common survey topics were rectal cancer decisionmaking, in 6 publications (16%), preoperative assessment of colorectal patients, in 5 publications (13%), and anal physiology: continence and defaecation, in 4 publications (11%). Publication of surveys was not related to the number of surveys distributed per year, the number of questions per survey, or the time required by respondents to complete the surveys.
Conclusion
Most of the CSSANZ-distributed surveys resulted in publications, and one third of the surveys contributed to higher degrees obtained by investigators. These surveys aid research into areas that are otherwise difficult to assess, often indicating areas for future research.

Abstract PDF

Purpose
We determined the outcomes of patients undergoing video-assisted anal fistula treatment (VAAFT) for fistulain-ano at the Philippine General Hospital.
Methods
Twenty consecutive adult patients who underwent the VAAFT procedure from 2016–2018 were included in this investigation. Information detailing baseline demographic and clinical data, fistula type and classification, and previous surgeries were retrieved from in-hospital and operative records. Operative time, identification of the internal opening, method of internal opening closure, and occurrence of immediate postoperative complications were determined. The status of the fistula was assessed at one month, 3 months, and 6 months postoperatively based on outpatient follow-up records. The primary outcomes were healing rate and recurrence rate. Secondary outcomes were 30-day morbidity, postoperative complications, and incontinence using the Wexner score.
Results
Eighteen patients (90%) had a preoperative diagnosis of complex fistula, and 13 patients (65%) had undergone a previous fistula surgery. Primary healing rate was 55% at 1 month, 63.16% at 3 months, and 78.95% at 6 months postoperatively. Eighteen patients (94.74%) maintained continence (Wexner score = 0) at 6 months.
Conclusion
Our study results suggest that VAAFT is a safe, minimally invasive technique for treatment of anal fistula and can preserve anal sphincter function. The technique has an acceptable healing rate with minimal complications.

Abstract PDF

Nasal metastases from colorectal cancer is rare. The presentation of nasal metastases is often very similar to primary nasal sinus adenocarcinoma. A high index of suspicion is required, especially in patients who have had a previous history of colorectal carcinoma. Histology is ultimately required for diagnosis. We describe 2 cases of nasal metastases from colorectal carcinoma, and discuss the presentation, diagnosis and management of the case. Such metastatic disease ultimately represents end-stage malignancy, and patients should be palliated.

Abstract PDF

The ideal intervention in the treatment of perianal fistula prevents the onset of infection to speed healing and prevent fistula recurrence while maintaining the function of the anal sphincter. Currently, there is no consensus on the best recommended surgical technique for perianal fistula management. Several studies have shown that fistulotomy was an easy and safe procedure for treatment of perianal fistula. Lateral internal sphincterotomy is the usual procedure performed on an anal fissure to decrease the anal sphincter tone. This study reports a combination of fistulotomy and contralateral internal sphincterotomy procedures for recurrent and complex perianal fistula to prevent recurrence. Here, we report 5 cases of recurrent and complex perianal fistula. The combination of fistulotomy and contralateral internal sphincterotomy is a relatively easy and safe procedure for complex perianal fistulae. In our cases, we found neither recurrence nor postoperative anal incontinence.
