Purpose
Robot-assisted surgery is readily applied to every type of colorectal surgeries. However, studies showing the safety and feasibility of robotic surgery (RS) have dealt with rectal cancer more than colon cancer. This study aimed to investigate how technical advantages of RS can translate into actual clinical outcomes that represent postoperative systemic response.
Methods
This study retrospectively reviewed consecutive cases in a single tertiary medical center in Korea. Patients with primary colon cancer who underwent curative resection between 2006 and 2012 were included. Propensity score matching was done to adjust baseline patient characteristics (age, sex, body mass index, American Society of Anesthesiologists physical status, tumor profile, pathologic stage, operating surgeon, surgery extent) between open surgery (OS), laparoscopic surgery (LS), and RS groups.
Results
After propensity score matching, there were 66 patients in each group for analysis, and there was no significant differences in baseline patient characteristics. Maximal postoperative leukocyte count was lowest in the RS group and highest in the OS group (P=0.021). Similar results were observed for postoperative neutrophil count (P=0.024). Postoperative prognostic nutritional index was highest in the RS group and lowest in the OS group (P<0.001). The time taken to first flatus and soft diet resumption was longest in the OS group and shortest in the RS group (P=0.001 and P<0.001, respectively). Among all groups, other short-term postoperative outcomes such as hospital stay and complications did not show significant difference, and oncological survival results were similar.
Conclusion
Better postoperative inflammatory indices in the RS group may correlate with their faster recovery of bowel motility and diet resumption compared to LS and OS groups.

Purpose
Despite advances in neoadjuvant chemoradiotherapy and anal sphincter-preserving surgery for rectal cancer, bowel dysfunction is still unavoidable and negatively affects patients’ quality of life. In this longitudinal study, we aimed to investigate the changes in bowel function with follow-up time and the effect of neoadjuvant chemoradiotherapy on bowel function following low anterior resection for rectal cancer.
Methods
In this study, 171 patients with upper or middle rectal cancer who underwent low anterior resection between 2012 and 2018 were included. Bowel function was assessed longitudinally with Memorial Sloan Kettering Cancer Center Bowel Function Instrument and Wexner scores every 6 months after restoration of bowel continuity. Patients with at least 2 follow-up visits were included.
Results
Overall, 100 patients received neoadjuvant chemoradiotherapy. Urgency, soilage, and fecal incontinence were noted within 24 months in the patients treated with neoadjuvant chemoradiotherapy. After 2 years of follow-up, significant bowel dysfunction and fecal incontinence were observed in the neoadjuvant chemoradiotherapy group. Low tumor level and neoadjuvant chemoradiotherapy were associated with delayed bowel dysfunction.
Conclusion
Neoadjuvant chemoradiotherapy in combination with low tumor level was significantly associated with delayed bowel dysfunction even after 2 years of follow-up. Therefore, careful selection and discussion with patients are paramount.

Purpose
The use of an ostomy for urination and defecation leads to reduced quality of life. Although many ostomy management strategies are needed, such strategies are often implemented by patients. Thus, there is a need for a home health care service platform that can be used in ostomy patient management.
Methods
We developed an ostomy patient management platform by identifying the needs of patients and medical staff through the Chronic Care Ostomy Self-Management Training Program in the United States and from studies conducted in Korea.
Results
The platform encompassed physical management, psychological management, maintenance of social function, spiritual stability, and home medical care. These components were implemented through monitoring, self-care guidance, and a community platform. For the monitoring function, patients entered their health status in a mobile application (app); the medical staff at the affiliated hospital then monitored the stoma status through a web interface.
Conclusion
Our platform allows medical staff to monitor ostomy patients through a web interface and help such patients to fully manage their ostomy at home using an app. We expect that the continued development of patient-oriented functions in our app will allow ostomy patients to experience quality-of-life improvements.

Purpose
Anal cancer is a rare disease in Korea, and thus survival analyses are limited by small sample sizes. This study used the Korea Central Cancer Registry (KCCR) for a survival analysis and for assessing characteristics of anal cancer in a large sample of Koreans.
Methods
From the KCCR, data on 3,615 patients who were diagnosed and treated for anal cancer from 1993 to 2015 were retrieved. Clinicopathologic variables including age, sex, histological type, and Surveillance Epidemiology and End Results (SEER) stage were reviewed, and a survival analysis was performed according to these variables.
Results
The 5-year relative survival rate improved from 39.7% in 1993–1995 to 66.5% in 2011–2015. Squamous cell carcinoma was the most common and showed the highest survival rate. Males and older patients (≥40 years and ≥70 years) showed poor prognoses.
Conclusion
The survival rate for anal cancer in Korea has improved steadily over time. The characteristics related to survival were the histological type, sex, and age. These statistics will be fundamental for future Korean anal cancer research.

Abstract PDF

Purpose
Upfront systemic chemotherapy with target agents has been recommended for patients with stage IV colon cancer. Some with partial response are considered for curative resection. There is high risk of developing postoperative complications following upfront systemic chemotherapy. We aimed to evaluate short-term perioperative outcomes of curative surgery after upfront chemotherapy in comparison with upfront surgery in patients with metastatic colon cancer.
Methods
Between January 2010 and October 2015, 146 patients (80 in the surgery first group, 66 in the upfront chemotherapy group) who underwent surgical resection before or after systemic chemotherapy for metastatic colon cancer were included in the present study. All decisions for treatment were made through a multidisciplinary team. Postoperative clinical outcomes and complications were analyzed to compare the groups.
Results
There was no difference between the 2 groups in terms of postoperative clinical outcomes. Overall complication rates were not different between the groups (surgery first group: 46.3% vs. upfront chemotherapy group: 60.6%; P = 0.084). When classified according to the Clavien-Dindo method, there was no difference between the 2 groups in terms of major complications (grade 3 or more) (surgery first group: 18.9% vs. upfront chemotherapy group: 27.5%; P = 0.374).
Conclusion
There was no significant increase in major postoperative complications in metastatic colon cancer patients who received upfront chemotherapy followed by curative surgery. Careful patient selection and treatment planning are important.

Abstract PDF

Purpose
Tailgut cysts are rare congenital or developmental lesions that arise from vestiges of the embryological hindgut. They are usually present in the presacral space. We report our single-center experience with managing tailgut cysts.
Methods
We conducted a retrospective analysis of 24 patients with tailgut cyst treated surgically at the Colorectal Surgery Department of Severance Hospital, Yonsei University, Seoul, South Korea, between 2007–2018.
Results
This study included 24 patients (18 females) with a median age of 51.5 years (range, 21–68 years). Ten cases were symptomatic and 14 were asymptomatic. Cysts were retrorectal in 21 patients. Cysts were below the coccyx level in 16 patients, opposite the coccyx in 6, and above the coccyx in 2. Cysts were supralevator in 5 patients, had a supra- and infralevator extension in 18 patients, and were infralevator in 1. Ten patients were managed using an anterior laparoscopic approach, 11 using a posterior approach, and 3 using a combined approach. Mean cyst size was 5.5 ± 2.7 cm. Postoperative complications were Clavien-Dindo (CD) classification grade II in 9 patients (37.5%) and CD grade III in 1 (4.2%). The posterior approach group showed the highest rate of complications (P = 0.021). Patients managed using a combined approach showed a larger cyst size (P < 0.001), longer operation times (P < 0.001), and a greater likelihood of tumor level above the coccyx (P = 0.002) compared to other approaches. The tumors of 2 male patients were malignant: 1 was a neuroendocrine tumor treated with radiotherapy, while the other was a closely followed adenocarcinoma. Median follow-up was 12 months (range, 1–66 months) with no recurrence.
Conclusion
Tailgut cysts are uncommon but can cause perineal or pelvic pain. Complete surgical excision via an appropriate approach according to tumor size, location, and correlation with adjacent pelvic floor muscles is the key treatment.

Purpose
The incidence of colorectal cancer (CRC) in Korea has increased remarkably during the past few decades. The present study investigated the characteristics and survival of patients with CRC in Korea as a function of time, tumor distribution, stage, sex, and age.
Methods
We retrieved clinical data on 326,712 CRC patients diagnosed between 1996 and 2015 from the Korea Central Cancer Registry. The incidence and the 5-year relative survival rates were compared across time period, tumor distribution, stage, sex, and age group.
Results
The percentage of patients with colon cancer increased from 49.5% in 1996–2000 to 66.4% in 2011–2015 while the percentage of patients with rectal cancer decreased from 50.5% to 33.6%. The 5-year relative survival rates for all CRCs improved from 58.7% in 1996–2000 to 75.0% in 2011–2015. For 1996–2000, survival rates were highest for patients with left-sided colon cancers, followed by those with right-sided, transverse, rectal, rectosigmoid cancers. For 2011–2015, the survival rates for patients with left-sided cancers were highest, followed by those with rectosigmoid, rectal, transverse, and right-sided colon cancers. Patients with local and regional, but not distant, SEER (Surveillance, Epidemiology, and End Results) stage tumors experienced significantly increased survival rates for 2006–2010 and 2011–2015. The proportion of CRC patients by age decreased in the order ≥70, 60–69, 50–59, 40–49, ≤39 years whereas survival rates decreased in the order 50–59, 60–69, 40–49, ≤39, ≥70 years.
Conclusion
Korean CRC has some distinct characteristics and survival patterns in terms of tumor distribution, stage, sex, and age. With time, survival outcomes have improved for both local and regional, but not distant, stage tumors.

Abstract PDF

Purpose

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been proposed for controlling peritoneal seeding metastasis in some kinds of cancers, including those of colorectal origin, but their safety and oncological benefits are subjects of debate. We present our early experience with those procedures.

Methods

Data were retrospectively collected from all patients with peritoneal carcinomatosis (PC) and pseudomyxoma peritonei (PMP) treated using CRS and HIPEC at Yonsei Cancer Center between July 2014 and July 2015. Short-term outcomes and risk factors for postoperative complications were analyzed.

Results

Twenty-three patients with PC (n = 18) and PMP (n = 5) underwent CRS and HIPEC. Median follow-up and age were 2 months and 54 years, respectively. The median peritoneal carcinomatosis index score was 15, and CC0-1 was achieved in 78.3% of all patients. The median operation time and bleeding loss were 590 minutes and 570 mL, respectively. Grade-IIIa/grade-IIIb complications occurred in 4.3% (n = 1)/26.1% (n = 6) of the patients within 30 days postoperatively, and no 30-day mortalities were reported. Factors related to postoperative complications with CRS and HIPEC were number of organ resection (P = 0.013), longer operation time (P < 0.001), and amount of blood loss (P = 0.003). All patients treated with cetuximab for recurred colorectal cancer had grade-III postoperative complication.

Conclusion

Our initial experience with CRS and HIPEC presented about 30% grade-III postoperative complications. Therefore, expert surgeons need to perform those procedures with great caution in selected patients who might benefit from it.

Abstract PDF

Purpose

Previous studies have demonstrated the prognostic impact of the prognostic nutritional index (PNI), a proposed indicator of immunonutritional statuses of surgical patients, on patients with various gastrointestinal cancers. Although the prognostic impact of the PNI on patients with colorectal cancer has been well established, its value has not been studied in patients treated with preoperative chemoradiation (pCRT). This study aimed to evaluate the prognostic impact of PNI on patients receiving pCRT for locally advanced rectal cancer (LARC).

Methods

Patients with LARC who underwent curative pCRT followed by surgical resection were enrolled. The PNI was measured in all patients before and after pCRT, and the difference in values was calculated as the PNI difference (dPNI). Patients were classified according to dPNI (<5, 5–10, and >10). Clinicopathologic parameters and long-term oncologic outcomes were assessed according to dPNI classification.

Results

No significant intergroup differences were observed in clinicopathologic parameters such as age, histologic grade, tumor location, tumor-node-metastasis stage, and postoperative complications. Approximately 53% of the patients had a mild dPNI (<5); only 15% had a high dPNI (>10). Univariate and multivariate analyses identified the dPNI as an independent prognostic factor for disease-free status (P < 0.01; hazard ratio [HR], 2.792; 95% confidence interval [CI], 1.577–4.942) and for cancer-specific survival (P = 0.012; HR, 2.469; 95%CI, 1.225–4.978).

Conclusion

The dPNI is predictive of long-term outcomes in pCRT-treated patients with LARC. Further prospective studies should investigate whether immune-nutritional status correction during pCRT would improve oncologic outcomes.

Abstract PDF

A rectal carcinoma, including primary an adenosquamous and a squamous cell carcinoma (SCC), is a very rare disease, accounting for 0.025% to 0.20% of all large-bowel malignant tumors. Because SCCs have a higher mortality than adenosquamous carcinomas, determining whether the primary rectal cancer exhibits an adenomatous component or a squamous component is important. While differentiating between these 2 components, especially in poorly differentiated rectal cancer, is difficult, specific immunohistochemical stains enable accurate diagnoses. Here, we report the use of immunohistochemical stains to distinguish between the adenomatous and the squamous components in 2 patients with low rectal cancer, a 58-year-old man and a 73-year-old woman, who were initially diagnosed using the histopathologic results for a poorly differentiated carcinoma. These data suggest that using these immunohistochemical stains will help to accurately diagnose the type of rectal cancer, especially for poorly differentiated carcinomas, and will provide important information to determine the proper treatment for the patient.

Abstract PDF

Purpose

This study compared the perioperative and pathologic outcomes between an extralevator abdominoperineal resection (APR) in the prone position and a conventional APR.

Methods

Between September 2011 and March 2014, an extralevator APR in the prone position was performed on 13 patients with rectal cancer and a conventional APR on 26 such patients. Patients' demographics and perioperative and pathologic outcomes were obtained from the colorectal cancer database and electronic medical charts.

Results

Age and preoperative carcinoembryonic antigen (CEA) level were significantly different between the conventional and the extralevator APR in the prone position (median age, 65 years vs. 55 years [P = 0.001]; median preoperative CEA level, 4.94 ng/mL vs. 1.81 ng/mL [P = 0.011]). For perioperative outcomes, 1 (3.8%) intraoperative bowel perforation occurred in the conventional APR group and 2 (15.3%) in the extralevator APR group. In the conventional and extralevator APR groups, 12 (46.2%) and 6 patients (46.2%) had postoperative complications, and 8 (66.7%) and 2 patients (33.4%) had major complications (Clavien-Dindo III/IV), respectively. The circumferential resection margin involvement rate was higher in the extralevator APR group compared with the conventional APR group (3 of 13 [23.1%] vs. 3 of 26 [11.5%]).

Conclusion

The extralevator APR in the prone position for patients with advanced low rectal cancer has no advantages in perioperative and pathologic outcomes over a conventional APR for such patients. However, through early experience with a new surgical technique, we identified various reasons for the lack of favorable outcomes and expect sufficient experience to produce better peri- or postoperative outcomes.

Abstract PDF

Four consecutive cases of a colonic stricture following a da Vinci robot-assisted ultra-low anterior resection (LAR) with coloanal anastomosis and diverting ileostomy for the treatment of rectal cancer are reported. The colonic strictures developed after early proximal colonic ischemia without anastomotic site leakage or disruption. All patients were treated with preoperative chemoradiation therapy. During the postoperative recovery period, patients developed colonic ischemia, presenting with a high, spiking fever, but without any symptoms of peritonitis. Patients were treated with conservative management (antibiotic therapy) and discharged after two weeks when in good condition. Several months after discharge, all four patients developed a long-segment colonic stricture from the anastomosis site to the distal colon. Management of the colon strictures, including the anastomotic site, involved colonic dilation with a Hegar dilator in an outpatient clinic for several months. The ileostomies in three patients could not be closed.

Purpose

Single-port plus one-port, reduced-port laparoscopic surgery (RPLS) may decrease collisions between laparoscopic instruments and the camera in a narrow, bony, pelvic cavity while maintaining the cosmetic advantages of single-incision laparoscopic surgery. The aim of this study is to describe our initial experience with and to assess the feasibility and safety of RPLS for tumor-specific mesorectal excisions (TSMEs) in patients with colorectal cancer.

Methods

Between May 2010 and August 2012, RPLS for TSME was performed in 20 patients with colorectal cancer. A single port with four channels through an umbilical incision and an additional port in the right lower quadrant were used for RPLS.

Results

The median operation time was 231 minutes (range, 160-347 minutes), and the estimated blood loss was 100 mL (range, 50-500 mL). We transected the rectum with one laparoscopic stapler in 17 cases (85%). The median time to soft diet was 4 days (range, 3-6 days), and the length of hospital stay was 7 days (range, 5-45 days). The median total number of lymph nodes harvested was 16 (range, 7-36), and circumferential resection margin involvement was found in 1 case (5%). Seven patients (35%) developed postoperative complications, and no mortalities occurred within 30 days. During the median follow-up period of 20 months (range, 12-40 months), liver metastasis occurred in 1 patient 10 months after surgery, and local recurrence was nonexistent.

Conclusion

RPLS for TSME in patients with colorectal cancer is technically feasible and safe without compromising oncologic safety. However, further studies comparing RPLS with a conventional, laparoscopic low-anterior resection are needed to prove the advantages of the RPLS procedure.

Abstract PDF

Purpose

The aim of this study is to assess the effects of age on the short-term outcomes of a laparoscopic resection of colorectal cancer in elderly (≥75 years old), as compared with younger (<75 years old), patients.

Methods

A retrospective analysis of patients who underwent laparoscopic surgery for colorectal cancer between January 2007 and December 2009 was performed. There were two groups: age <75 years old (group A) and age ≥75 years old (group B). The perioperative outcomes between group A and group B were compared.

Results

The study included 824 patients in group A and 92 patients in group B. The body mass index (BMI) and the American Society of Anesthesiologists (ASA) score were significantly different between group B and group A (BMI: 22.5 vs. 23.5, P = 0.002; ASA score: 1.88 vs. 1.48, P = 0.001). Mean operating times were similar between the groups (325.4 minutes vs. 351.6 minutes, P = 0.07). We observed a higher overall complication rate in group B than in group A (12.0% vs. 6.2%, P = 0.047), but the number of severe complications of Accordion Severity Classification ≥3 (those that required an invasive procedure) was not significantly different between the two groups (6.5% vs. 3.4%, P = 0.142). There was no significant difference in the length of hospital stay (13.0 days vs. 12.0 days, P = 0.053).

Conclusion

Although the elderly patients had a significantly higher overall postoperative complication rate, no significant difference was seen in either the number of severe complications of Accordion Severity Classification ≥3 or in the length of hospital stay. A laparoscopic colorectal cancer resection in elderly patients, especially those aged 75 years or older, is safe and feasible.
