Abstract PDF

Purpose
Local excision (LE) is an alternative initial treatment for clinical T1 rectal cancer, and has avoided potential morbidity. This study aimed to evaluate the clinical outcomes of LE compared with total mesorectal excision (TME) for clinical T1 rectal cancer.
Methods
Between January 2000 and December 2011, we retrospectively reviewed from multicenter data in patients with clinically suspected T1 rectal cancer treated with either LE or TME. Of 1,071 patients, 106 were treated with LE and 965 were treated with TME. The data were analyzed using propensity score matching, with each group comprising 91 patients.
Results
After propensity score matching, the median follow-up time was 60.8 months (range, 0.6–150.6 months). After adjustment for the necessary variables, patients who underwent LE showed a significantly higher local recurrence rate than did those who underwent TME; however, there were no differences in disease-free survival and overall survival. In the multivariate analysis, age (hazard ratio [HR], 9.620; 95% confidence interval [CI], 3.415–27.098; P<0.001) and angiolymphatic invasion (HR, 3.63; 95% confidence interval, 1.33–9.89; P=0.012) were independently associated with overall survival. However, LE was neither associated with overall survival nor disease-free survival.
Conclusion
LE for clinical T1 rectal cancer yielded a higher local recurrence rate than did TME. Nevertheless, LE provided comparable overall survival rate and can be proposed as an optional treatment in terms of organ-preserving strategies.

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
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
This study evaluated the oncologic outcomes of locally advanced rectal cancer patients who underwent preoperative neoadjuvant chemoradiotherapy (CRT) followed by surgery and determined the prognostic significance of pathologic complete response (pCR).
Methods
Between January 2002 and December 2015, 580 patients with rectal cancer who underwent surgery after neoadjuvant CRT were identified. Survival according to tumor response to CRT and pathologic stage was analyzed using the Kaplan-Meier method, and the Cox proportional hazard model was used to identify factors associated with survival outcomes.
Results
A total of 111 patients (23.7%) achieved pCR while the other 469 patients showed residual disease. Patients with pCR had a lower pretreatment carcinoembryonic antigen level and earlier cT classification than those with residual disease. With a median follow-up of 78 months, disease-free survival (DFS) and overall survival (OS) were significantly better in the pCR group than in the residual disease group. The 5-year DFS and 5-year OS for patients with ypStage 0, I, II, or III were 92.5%, 85.1%, 72.2%, 54.3% (P < 0.001) and 94.5%, 91.0%, 83.1%, 69.3%, respectively (P < 0.001). Pathologic AJCC stage after CRT was the most statistically significant independent predictor of OS (HR, 6.97 [95% confidence interval, 3.16–15.39] for stage III vs. stage 0) and DFS (HR, 7.30 [95% confidence interval, 3.63–14.67] for stage III vs. stage 0).
Conclusion
Rectal cancer patients who achieved pCR showed improved survival compared to those with residual disease after preoperative CRT. Moreover, pCR was an independent indicator of OS and DFS, and pathologic AJCC stage was correlated with survival after preoperative CRT.

Abstract PDF: An inflammatory myofibroblastic tumor (IMT) is a solid tumor of unknown etiology frequently affecting children and young adults and commonly affecting the lung or orbital region. We present a case involving a 41-year-old man who had an IMT combined with Mycobacterium tuberculosis infection in the retroperitoneum. He presented with only pain in the right lower abdomen without accompanying symptoms; a retroperitoneal mass was found on computed tomography. The tumor had invaded the end of the ileum and was attached to the omentum, so mass excision could not be performed. The tumor was completely excised surgically and had histological features diagnostic of an IMT. Histologic findings of the omentum were positive for Ziehl-Nielsen staining for acid-fast bacilli and for a positive polymerase chain reaction for M. tuberculosis. The patient had no apparent immune disorder. These findings made this case exceptional because IMTs, which are mostly due to atypical mycobacteria, have been found mainly in immunocompromised patients.

Purpose
Stage-IIIC colon cancer is an advanced disease; however, its oncologic outcomes and prognostic factors remain unclear. In this study, we aimed to determine the predictors of disease-free survival (DFS) in patients with stage-IIIC colon cancer.
Methods
From a multicenter database, we retrospectively enrolled 611 patients (355 men and 256 women) who had undergone a potentially curative resection for a stage-IIIC colon adenocarcinoma between 2003 and 2011. The primary end-point was the 5-year DFS.
Results
The median age was 62 years; 213 and 398 patients had right-sided colon cancer (RCC) and left-sided colon cancer (LCC), respectively. The 5-year DFS in all patients was 52.0%; median follow-up time was 35 months (range, 1–134 months). A multivariate Cox regression revealed that female sex (hazard ratio [HR], 1.50; 95% confidence interval [CI], 1.19–1.90; P < 0.01), right-sided tumor location (HR, 1.65; 95% CI, 1.29–2.11; P < 0.01), lymphatic invasion (HR, 1.52; 95% CI, 1.08–2.15; P < 0.01) and a high (≥0.4) metastatic lymph node ratio (HR, 3.72; 95% CI, 2.63–5.24; P < 0.01) were independent predictors of worse 5-year DFS. Female patients with RCC were 1.79 fold more likely to experience recurrence than male patients with LCC.
Conclusion
Female sex and right-sided tumor location are associated with higher tumor recurrence rates in patients with stage-IIIC colon cancers. Aggressive treatment and close surveillance should be planned for patients in these groups.

Purpose

Perianal lesions are common in Crohn disease, but their clinical course is unpredictable. Nevertheless, predicting the clinical course after surgery for perianal Crohn disease (PCD) is important because repeated operations may decrease patient's quality of life. The aim of this study was to predict the risk of reoperation in patients with PCD.

Methods

From September 1994 to February 2010, 377 patients with PCD were recruited in twelve major tertiary university-affiliated hospitals and two specialized colorectal hospitals in Korea. Data on the patient's demographics, clinical features, and surgical outcomes were analyzed.

Results

Among 377 patients, 227 patients were ultimately included in the study. Among the 227 patients, 64 patients underwent at least one reoperation. The median period of reoperation following the first perianal surgery was 94 months. Overall 3-year, 5-year, and 10-year cumulative rates of reoperation-free individuals were 68.8%, 61.2%, and 50.5%, respectively. In multivariate analysis (Cox-regression hazard model), reoperation was significantly correlated with an age of onset less than 20 years (hazard ratio [HR], 1.93; 95% confidence interval [CI], 1.07-3.48; P = 0.03), history of abdominal surgery (HR, 1.99; 95% CI, 1.08-3.64; P = 0.03), and the type of surgery. Among types of surgery, fistulotomy or fistulectomy was associated with a decreased incidence of reoperation in comparison with incision and drainage (HR, 0.19; 95% CI, 0.09-0.42; P < 0.001).

Conclusion

Young age of onset and a history of abdominal surgery were associated with a high risk of reoperation for PCD, and the risk of reoperation were relatively low in fistulotomy or fistulectomy procedures.

Abstract PDF

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.

Purpose

This study prospectively investigated the effects of biofeedback therapy on objective anorectal function and subjective bowel function in patients after sphincter-saving surgery for rectal cancer.

Methods

Sixteen patients who underwent an ileostomy were randomized into two groups, one receiving conservative management with the Kegel maneuver and the other receiving active biofeedback before ileostomy closure. Among them, 12 patients (mean age, 57.5 years; range, 38 to 69 years; 6 patients in each group) completed the study. Conservative management included lifestyle modifications, Kegel exercises, and medication. Patients were evaluated at baseline and at 1, 3, 6, and 12 months after ileostomy closure by using anal manometry, modified Wexner Incontinence Scores (WISs), and fecal incontinence quality of life (FI-QoL) scores.

Results

Before the ileostomy closure, the groups did not differ in baseline clinical characteristics or resting manometric parameters. After 12 months of follow-up, the biofeedback group demonstrated a statistically significant improvement in the mean maximum squeezing pressure (from 146.3 to 178.9, P = 0.002). However, no beneficial effect on the WIS was noted for biofeedback compared to conservative management alone. Overall, the FI-QoL scores were increased significantly in both groups after ileostomy closure (P = 0.006), but did not differ significantly between the two groups.

Conclusion

Although the biofeedback therapy group demonstrated a statistically significant improvement in the maximum squeezing pressure, significant improvements in the WISs and the FI-QoL scores over time were noted in both groups. The study was terminated early because no therapeutic benefit of biofeedback had been demonstrated.

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.

Purpose

Obtaining a detailed family history through detailed pedigree is essential in recognizing hereditary colorectal cancer (CRC) syndromes. This study was performed to assess the current knowledge and practice patterns of surgery residents regarding familial risk of CRC.

Methods

A questionnaire survey was performed to evaluate the knowledge and the level of recognition for analyses of family histories and hereditary CRC syndromes in 62 residents of the Department of Surgery, Seoul National University Hospital. The questionnaire consisted of 22 questions regarding practice patterns for, knowledge of, and resident education about hereditary CRC syndromes.

Results

Two-thirds of the residents answered that family history should be investigated at the first interview, but only 37% of them actually obtained pedigree detailed family history at the very beginning in actual clinical practice. Three-quarters of the residents answered that the quality of family history they obtained was poor. Most of them could diagnose hereditary nonpolyposis colorectal cancer and recommend an appropriate colonoscopy surveillance schedule; however, only 19% knew that cancer surveillance guidelines differed according to the family history. Most of our residents lacked knowledge of cancer genetics, such as causative genes, and diagnostic methods, including microsatellite instability test, and indicated a desire and need for more education regarding hereditary cancer and genetic testing during residency.

Conclusion

This study demonstrated that surgical residents' knowledge of hereditary cancer was not sufficient and that the quality of the family histories obtained in current practice has to be improved. More information regarding hereditary cancer should be considered in education programs for surgery residents.

Purpose

Early diagnostic work-up in patients with clinical symptoms of colorectal cancer (CRC) is important to achieve good treatment results. In this study, we investigated clinical symptoms when a diagnosis of CRC was made in patients who had a surgical resection, especially focusing on the relevance of constipation to CRC.

Methods

The clinical symptoms of 17,415 CRC patients who had curative surgery from January 2010 to December 2012 were collected from 24 training hospitals of surgery.

Results

The number of symptomatic patients before the diagnosis of CRC was 11,085 (63.7%). Hematochezia or melena, abdominal pain, anemia, and constipation were more often found in female than male patients while bowel habit change was more common in male patients. Considering age, bowel habit change and hematochezia or melena were more common in patients younger than 60. Anemia and constipation, however, were more common in patients older than 60. According to the group classification based on age, patients older than 60 had experienced more constipation (P = 0.049). Moreover, patients with constipation tended to have a more advanced disease status (P < 0.001).

Conclusion

In patients who had surgery due to CRC, bleeding, abdominal pain, bowel habit change and constipation were the most frequent symptoms before diagnosis. Although whether or not constipation is a cause of CRC is unclear, it is one of the important clinical symptoms that presents in patients with CRC, and patients with a symptom of constipation tend to present with a more advanced CRC stage.

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.
