Abstract PDF Supplementary 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.

Purpose
The Korean Society of Coloproctology has been conducting Colorectal Cancer Awareness Campaign, also known as the Gold Ribbon Campaign, every September since 2007. The 2022 campaign was held through a metaverse platform targeting the younger age group under the slogan of raising awareness of early-onset colorectal cancer (CRC). This study aimed to analyze the impact of the 2022 campaign on a metaverse platform.
Methods
Anonymized survey data were collected from participants in the metaverse campaign from September 1 to 15, 2022. The satisfaction score of the participants was evaluated by sex, age group, and previous campaign participation status.
Results
During the campaign, 2,770 people visited the metaverse. Among them, 455 people participated in the survey (response rate, 16.4%). Approximately 95% of the participants reported being satisfied with the information provided by the campaign, understood the necessity of undergoing screening for and prevention of early-onset CRC, and were familiar with the structure of the metaverse. The satisfaction score for campaign information tended to decrease as the participants’ age increased. When the participants’ overall level of satisfaction with the metaverse platform was assessed, teenagers scored particularly lower than the other age groups. The satisfaction scores for CRC information provided in the metaverse, as well as the scores for recognizing the seriousness and necessity of screening for early-onset CRC, indicated a high positive tendency (P<0.001).
Conclusion
Most of the 2022 Gold Ribbon Campaign participants were satisfied with the metaverse platform. Medical society should pay attention to increasing participation in and satisfaction with future public campaigns.

Abstract PDF

Purpose
This study aimed to evaluate the safety and feasibility of single-port laparoscopic surgery (SLS) for appendiceal mucinous neoplasm (AMN) when compared with conventional laparoscopic surgery (CLS).
Methods
This retrospective study enrolled patients who underwent surgery for AMN between July 2014 and June 2020 at Seoul National University Bundang Hospital. Patient demographics, surgical data, pathology, hospital stay, postoperative morbidity, and follow-up data were extracted from electronic records for analysis.
Results
We enrolled 18 patients who underwent SLS and 22 who underwent CLS. The SLS group included patients who underwent partial cecectomy (14 patients), ileocecectomy (3 patients), and right hemicolectomy (1 patient). The CLS group included patients who underwent appendectomy (4 patients), partial cecectomy (11 patients), ileocecectomy (5 patients), and right hemicolectomy (2 patients). Operation type was not significantly different between groups (P = 0.213). No patient required open surgery in the SLS group in contrast to the CLS group (13.6%; P = 0.238). The operative time tended to be shorter in the SLS group than the CLS group (median [interquartile range]: 52.5 minutes [40–65.2 minutes] and 60 minutes [40–120 minutes], respectively; P = 0.251). Morbidity was 5.5% in the SLS group and 9.0% in the CLS group (P = 0.692). Surgical margins were clear in all cases. The median duration of postoperative hospital stay was 2.0 and 4.0 days in the SLS and CLS groups, respectively (P = 0.013). No recurrence occurred in either group during follow-up.
Conclusion
This study indicates that SLS is a safe and feasible surgical approach for AMN.

Abstract PDF

Purpose
This study aimed to evaluate real-world clinical outcomes from surgically treated patients for sigmoid volvulus.
Methods
Five tertiary centers participated in this retrospective study with data collected from October 2003 through September 2018, including demographic information, preoperative clinical data, and information on laparoscopic/open and elective/emergency procedures. Outcome measurements included operation time, postoperative hospitalization, and postoperative morbidity.
Results
Among 74 patients, sigmoidectomy was the most common procedure (n = 46), followed by Hartmann’s procedure (n = 23), and subtotal colectomy (n = 5). Emergency surgery was performed in 35 cases (47.3%). Of the 35 emergency patients, 34 cases (97.1%) underwent open surgery, and a stoma was established for 26 patients (74.3%). Elective surgery was performed in 39 cases (52.7%), including 21 open procedures (53.8%), and 18 laparoscopic surgeries (46.2%). Median laparoscopic operation time was 180 minutes, while median open surgery time was 130 minutes (P < 0.001). Median postoperative hospitalization was 11 days for laparoscopy and 12 days for open surgery. There were 20 postoperative complications (27.0%), and all were resolved with conservative management. Emergency surgery cases had a higher complication rate than elective surgery cases (40.0% vs. 15.4%, P = 0.034).
Conclusion
Relative to elective surgery, emergency surgery had a higher rate of postoperative complications, open surgery, and stoma formation. As such, elective laparoscopic surgery after successful sigmoidoscopic decompression may be the optimal clinical option.

Abstract PDF

Purpose
Single-port laparoscopic techniques can be optimized with confined incisions. This approach has an intraoperative advantage of excellent visualization of the correct intestinal segment for exteriorization, along with direct visual control of the extraction to avoid twisting. However, only a few studies have verified the efficacy of the technique. Thus, this study assessed the results of single-port laparoscopic stoma creation for fecal diversion, specifically focusing on feasibility, safety, and efficacy.
Methods
Patients who underwent single-incision enterostomy performed by a single surgeon were included. Data on demographics, indications for and chosen procedure, and operation results were retrospectively collected and analyzed.
Results
Between April 2015 and January 2018, a total of 13 patients (8 males, 5 females) with a mean age of 57.7 years (range, 41–83 years) underwent single-port ileostomy creation. The most common reason for diversion was palliative ileostomy for colon obstruction or fistula from peritoneal malignancy (n = 12), followed by colonic fistula with necrotizing pancreatitis (n = 1). There were no cases of conversion to open or multiport laparoscopic surgery. The mean operative time was 54 minutes (range, 37–118 minutes), and the median length of hospital stay was 8 days (range, 2–211 days). A postoperative complication, aspiration pneumonia, was documented in 1 patient and treated conservatively. The mean duration of bowel movement was 0.7 days (range, 0–4 days). All stomas had good function, and there was no 30-day mortality.
Conclusion
Single-port laparoscopic ileostomy in patients with a palliative setting could be a safe and feasible option for fecal diversion.

Purpose
We aimed to investigate the extent of heterogeneity in medical terminology between South and North Korea by comparing medical terms related to the colorectal system.
Methods
North Korean medical terms were collected from the sections on diseases of the small intestine and colon in a surgery textbook from North Korea, and those terms were compared with their corresponding terms in a South Korean medical terminology textbook. The terms were categorized as either identical, similar, showing disparity, or not used in South Korea. In a subsection analysis, the terms were allocated to pathophysiology, diagnosis, symptoms and examination, drugs, testing, treatment, or others according to the categorization used in the textbook.
Results
We found 705 terms in the North Korean textbook, most of which were pathophysiological terms (206, 29.2%), followed by diagnostic terms (165, 23.4%) and symptom and examination terms (122, 17.3%). Treatment-, drug-, and testing-related terms constituted 15.5%, 5.8%, and 4.1% of the 705 terms, respectively. There were 331 identical terms (47.0%) and 146 similar terms (20.7%); 126 terms (17.9%) showed disparity. Another 102 terms (14.5%) were not used in South Korea. The pathophysiological terms were the least heterogeneous, with 61.2% being identical terms used in both countries. However, 26.8% of the terms in the drug category were not used in South Korea.
Conclusion
The present study showed that less than 50% of the terms for the colorectal system used in South and North Korea were identical. As the division between South and North Korea persists, the heterogeneity of medical terminology is expected to increase.

Purpose

The Korean Society of Coloproctology holds its annual colorectal awareness month every September. This study analyzed the users and the contents of Korean tweets regarding colorectal cancer and estimated the transmissibility of the awareness campaign among Twitter users.

Methods

Prospective data collection was employed to accumulate Korean tweets containing the keywords "colorectal cancer," "colorectal cancer awareness campaign," "gold ribbon," and/or "love handle," from August 1 to September 30, 2014. Twitter users and contents were analyzed, and the credibility of information-sharing tweets throughout the study period was evaluated.

Results

In total, 10,387 tweets shared by 1,452 unique users were analyzed. As for users, 57.8% were individuals whereas 5.8% were organizations/communities; spambots accounted for a considerable percentage (36.4%). As for content, most tweets were spam (n = 8,736, 84.1%), repetitively advertising unverified commercial folk remedies, followed by tweets that shared information (n = 1,304, 12.6%) and non-information (n = 347, 3.3%). In the credibility assessment, only 80.6% of the information-sharing tweets were medically correct. After spam tweets had been excluded, a significant increase was seen in the percentage of information-sharing tweets (77.1% to 81.1%, P = 0.045) during the awareness campaign month.

Conclusion

Most Korean tweets regarding colorectal cancer during the study months were commercial spam tweets; informative public tweets accounted for an extremely small percentage. The transmissibility of the awareness campaign among Twitter users was questionable at best. To expand the reach of credible medical information on colorectal cancer, public health institutions and organizations must pay greater attention to social media.

This study was conducted to identify the effectiveness of a preoperative comprehensive geriatric assessment (CGA) for predicting postoperative morbidity in elderly patients who underwent surgery for colorectal cancer.

Methods

Elderly patients (≥70 years old) who underwent surgery for colorectal cancer at a tertiary hospital in Korea were identified, and their cases were analyzed using data from a prospectively collected database to establish an association between major postsurgical complications and 'high-risk' patient as defined by the CGA.

Results

A total of 240 patients, with a mean age of 76.7 ± 5.2 years, were enrolled. Ninety-five patients (39.6%) were classified as "high-risk" and 99 patients (41.3%) as having postoperative complications. The univariate analysis indicated that risk factors for postoperative complications were age, American Society of Anesthesiologists physical status classification, serum hemoglobin, carcinoembryonic antigen, cancer stage, and "high-risk" status. The multivariable analyses indicated that "high-risk" status (odds ratio, 2.107; 95% confidence interval, 1.168–3.804; P = 0.013) and elevated preoperative carcinoembryonic antigen (odds ratio, 2.561; 95% confidence interval, 1.346–4.871, P = 0.004) were independently associated with postoperative complications. A multivariable analysis of the individual CGA domains indicated that high comorbidities and low activities of daily living were significantly related with postoperative complications.

Conclusion

A preoperative CGA indicating "high-risk" was associated with major postoperative complications in elderly patients who underwent surgery for colorectal cancer. Thus, using the CGA to identify elderly colorectal-cancer patients who should be given more care during postoperative management may be clinically beneficial.

Purpose

Crohn disease is characterized by high rates of recurrence and reoperations. However, few studies have investigated long-term surgical outcomes in Asian populations. We investigated risk factors for reoperation, particularly those associated with anti-tumor necrosis factor-α (anti-TNF-α) antibody use, and long-term follow-up results.

Methods

We reviewed the records of 148 patients (100 males and 48 females) who underwent surgery for gastrointestinal Crohn disease and retrospectively analyzed long-term outcomes and risk factors.

Results

The mean age at diagnosis was 28.8 years. Thirty-eight patients (25.7%) received monoclonal antibody treatment before reoperation. A small bowel and colon resection was most commonly performed (83 patients, 56.1%). The median follow-up was 149 months, during which 47 patients underwent reoperation. The median interval between the primary and the secondary surgeries was 65 months, with accumulated reoperation rates of 16.5%, 31.8%, and 57.2% after 5, 10, and 15 years, respectively. Obstruction was the most common indication for reoperation (37 patients, 25.0%). In a multivariable analysis, age <17 years at diagnosis (A1) (odds ratio [OR], 2.20; P = 0.023), penetrating behavior (B3) (OR, 4.39; P < 0.001), and no azathioprine use (OR, 2.87; P = 0.003) were associated with reoperation. Anti-TNF-α antibody use did not affect the reoperation rate (P = 0.767).

Conclusion

We showed a high reoperation rate regardless of treatment with anti-TNF-α antibody, which indicates that recurrent surgery is still needed to cure patients with gastrointestinal Crohn diseases. Younger age at primary operation, penetrating behavior, and no azathioprine use were significant factors associated with reoperation for gastrointestinal Crohn disease.

Abstract PDF

Purpose

A rectourethral fistula (RUF) is an uncommon complication resulting from surgery, radiation or trauma. Although various surgical procedures for the treatment of an RUF have been described, none has gained acceptance as the procedure of choice. The aim of this study was to review our experience with surgical management of RUF.

Methods

The outcomes of 6 male patients (mean age, 51 years) with an RUF who were operated on by a single surgeon between May 2005 and July 2012 were assessed.

Results

The causes of the RUF were iatrogenic in four cases (two after radiation therapy for rectal cancer, one after brachytherapy for prostate cancer, and one after surgery for a bladder stone) and traumatic in two cases. Fecal diversion was the initial treatment in five patients. In one patient, fecal diversion was performed simultaneously with definitive repair. Four patients underwent staged repair after a mean of 12 months. Rectal advancement flaps were done for simple, small fistula (n = 2), and flap interpositions (gracilis muscle flap, n = 2; omental flap, n = 1) were done for complex or recurrent fistulae. Urinary strictures and incontinence were observed in patients after gracilis muscle flap interposition, but they were resolved with simple treatments. The mean follow-up period was 28 months, and closure of the fistula was achieved in all five patients (100%) who underwent definitive repairs. The fistula persisted in one patient who refused further definitive surgery after receiving only a fecal diversion.

Conclusion

Depending on the severity and the recurrence status of RUF, a relatively simple rectal advancement flap repair or a more complex gracilis muscle or omental flap interposition can be used to achieve closure of the fistula.

Abstract PDF

Inappropriate therapies for hemorrhoids can lead to various complications including anorectal stricture. We report a patient presenting with catastrophic rectal perforation due to severe anal stricture after inappropriate hemorrhoid treatment. A 67-years old man with perianal pain visited the emergency room. The hemorrhoids accompanied by constipation, had tortured him since his youth. Thus he had undergone injection sclerotherapy several times by an unlicensed therapist and hemorrhoidectomy twice at the clinics of private practitioners. His body temperature was as high as 38.5℃. The computed tomographic scan showed a focal perforation of posterior rectal wall. The emergency operation was performed. The fibrotic tissues of the anal canal were excised. And then a sigmoid loop colostomy was constructed. The patient was discharged four days following the operation. This report calls attention to the enormous risk of unlicensed injection sclerotherapy and overzealous hemorrhoidectomy resulting in scarring, progressive stricture, and eventual rectal perforation.

Abstract PDF

Purpose

An anal condyloma is a proliferative disease of the genital epithelium caused by the human papillomavirus. This condition is most commonly seen in male homosexuals and is frequently recurrent. Some reports have suggested that immunosuppression is a risk factor for recurrence of a condyloma. Thus, we investigated the risk factors for a recurrent anal condyloma in human immunodeficiency virus (HIV)-positive patients.

Methods

We retrospectively analyzed 85 consecutive patients who were diagnosed with and underwent surgery for an anal condyloma from January 2007 to December 2011. Outcomes were analyzed based clinical and immunologic data.

Results

Recurrent anal condylomata were found in 25 patients (29.4%). Ten cases (40.0%) were within postoperative 3 months. At postoperative 6 months, the CD4 lymphocyte count in the recurrent group was lower than it was in the nonrecurrent group (P = 0.023).

Conclusion

CD4-mediated immunosuppression is a risk factor for recurrent anal condylomata in HIV-positive patients.

Abstract PDF

Purpose

We analyzed the clinical data of T3 colorectal cancer patients to assess whether T3 subdivision correlates with node (N) or metastasis (M) staging and stage-independent factors.

Methods

Five hundred fifty-five patients who underwent surgery for primary colorectal cancer from January 2003 to December 2009 were analyzed for T3 subdivision. T3 subdivision was determined by the depth of invasion beyond the outer border of the proper muscle (T3a, <1 mm; T3b, 1 to 5 mm; T3c, >5 to 15 mm; T3d, >15 mm). We investigated the correlation between T3 subdivision and N, M staging and stage-independent prognostic factors including angiolymphatic invasion (ALI), venous invasion (VI) and perineural invasion (PNI).

Results

The tumors of the 555 patients were subclassified as T3a in 86 patients (15.5%), T3b in 209 patients (37.7%), T3c in 210 patients (37.8%) and T3d in 50 patients (9.0%). The nodal metastasis rates were 39.5% for T3a, 56.5% for T3b, 75.7% for T3c and 74.0% for T3d. The distant metastasis rates were 7.0% for T3a 9.1% for T3b, 27.1% for T3c and 40.0% for T3d. Both N and M staging correlated with T3 subdivision (Spearman's rho = 0.288, 0.276, respectively; P < 0.001). Other stage-independent prognostic factors correlated well with T3 subdivision (Spearman's rho = 0.250, P < 0.001 for ALI; rho = 0.146, P < 0.001 for VI; rho = 0.271, P < 0.001 for PNI).

Conclusion

Subdivision of T3 colorectal cancer correlates with nodal and metastasis staging. Moreover, it correlates with other prognostic factors for colorectal cancer.

Abstract PDF

An anorectal foreign body can cause serious complications such as incontinence, rectal perforation, peritonitis, or pelvic abscess, so it should be managed immediately. We experienced two cases of operative treatment for a self-inserted anorectal foreign body. In one, the foreign body could not be removed as it was completely impacted in the anal canal. We failed to remove it through the anus. A laparotomy and removal of the foreign body was performed by using an incision on the rectum. Primary colsure and a sigmoid loop colostomy were done. A colostomy take-down was done after three months. The other was a rectal perforation from anal masturbation with a plastic device. We performed primary repair of the perforated rectosigmoid colon, and we didea sigmoid loop colostom. A colostomy take-down was done three months later. Immediate and proper treatment for a self-inserted anorectal foreign body is important to prevent severe complications, and we report successful surgical treatments for problems caused by anorectal foreign bodies.

Abstract PDF

Purpose

Parastomal hernia is a major complication of an intestinal stoma. This study was performed to compare the results of various operative methods to treat parastomal hernias.

Methods

Results of surgical treatment for parastomal hernias (postoperative recurrence, complications and postoperative hospital stays) were surveyed in 39 patients over an 11-year period. The patients enrolled in this study underwent surgery by a single surgeon to exclude surgeon bias.

Results

Seventeen patients were male, and twenty-two patients were female. The mean age was 65.9 years (range, 36 to 86 years). The stomas were 35 sigmoid-end-colostomies (90%), 2 loop-colostomies (5%), and 2 double-barrel-colostomies. Over half of the hernias developed within two years after initial formation. Stoma relocation was performed in 8 patients, suture repair in 14 patients and mesh repair in 17 patients. Seven patients had recurrence of the hernia, and ten patients suffered from complications. Postoperative complications and recurrence were more frequent in stoma relocation than in suture repair and mesh repair. Emergency operations were performed in four patients (10.3%) with higher incidence of complications but not with increased risk of recurrence. Excluding emergency operations, complications of relocations were not higher than those of mesh repairs. Postoperative hospital stays were shortest in mesh repair patients.

Conclusion

In this study, mesh repair showed low recurrence and a low complication rate with shorter hospital stay than relocation methods, though these differences were not statistically significant. Further studies, including randomized trials, are necessary if more reliable data on the surgical treatment of parastomal hernias are to be obtained.

Purpose

Since 2004, the National Cancer Screening Program of Korea has included colorectal cancer screening based on primary screening with the fecal occult blood test (FOBT). We report on the clinical features of colorectal cancer detected by the National Cancer Screening Program.

Methods

We retrospectively analyzed 577 patients who underwent elective surgery for colorectal cancer at the Seoul National University Hospital between January 2008 and December 2009. We compared the clinical features of colorectal cancers detected by the National Cancer Screening Program (NCSP group) with those of the control group in terms of age, gender, preoperative symptom, location of the tumor, surgical technique and tumor-node-metastasis (TNM) stage.

Results

Age, gender, location of the tumor and operation types were not different between the two groups. The proportion of asymptomatic patients was significantly higher in the NCSP group than it was in the control group (86.5% vs. 20.0%; P < 0.001). The proportion of less invasive lesions (T1 or T2) was significantly higher in the NCSP group (46.3% vs. 27.7%; P = 0.002). The pathologic stages of the colorectal cancers in the NCSP group were I, 40.3%; II, 17.9%; III, 40.3% and IV, 1.5% whereas in the control group, they were I, 20.8%; II, 32.9%; III, 34.9% and IV, 11.4%. The proportion of stage I cancer was significantly higher in the NCSP group than in the control group (40.3% vs. 20.8%; P = 0.006).

Conclusion

Our study demonstrates the FOBT in the NCSP is effective in early detection of colorectal cancer.

Abstract PDF

Purpose

Management strategy in acute appendicitis patients initially presenting with abscess or mass is surrounded with controversy. This study was performed to identify the outcomes of management for this condition.

Methods

We retrospectively analyzed prospectively registered 76 patients (male:female = 39:37; mean age, 50.8 years) with appendicitis presenting with abscess or mass over a 9-year period at the Seoul National University Hospital. Patients were divided into three groups (emergency operation group, delayed operation group, and follow-up group), and clinical characteristics and outcomes of treatment were investigated.

Results

Twenty-eight patients (36.8%) underwent an emergency operation. Of the remaining 48 patients, 20 (41.7%) were initially treated with conservative management through the use of antibiotics only; the other 28 (58.3%) with and additional ultrasound-guided percutaneous drainage of the abscess. Twenty-six (54.2%) patients underwent planned operations after conservative management, and 22 (45.8%) were followed without surgery (median duration, 37.8 month), of which 3 (13%) underwent an appendectomy due to recurrent appendicitis (mean of 56.7 days after initial attack). There were no statistical differences in types of operation performed (appendectomy or ileocecectomy), postoperative complications, and postoperative hospital stay among the patients who underwent emergency operations, delayed operations and operations for recurrence during follow-up.

Conclusion

Although the recurrence rate was relatively low after conservative management for appendicitis patients presenting with abscess or mass, there was no difference in surgical outcome between the emergent, elective, or recurrent groups. Our results indicate that proper management of appendicitis with abscess or mass can be selected according to surgeon's preference.
