Abstract PDF

Even in patients undergoing an optimal surgical technique (e.g., total mesorectal excision), radiotherapy provides a significant benefit in the local control of rectal cancer. Compared with postoperative treatment, chemoradiotherapy given preoperatively has been shown to decrease local recurrence rates and toxicity. Additionally, preoperative chemoradiotherapy permits the early identification of tumor responses to this cytotoxic treatment by surgical pathology. Pathological parameters reflecting the tumor response to chemoradiotherapy have been shown to be surrogate markers for long-term clinical outcomes. Post-chemoradiotherapy downstaging from cStage II-III to ypStage 0-I indicates a favorable prognosis, with no difference between ypStage 0 and ypStage I. Research is ongoing to develop useful tools (clinical, molecular, and radiological) for clinical determination of the pathologic chemoradiotherapeutic response before surgery, and possibly even before preoperative treatment. In the future, risk-adapted strategies, including intensification of preoperative therapy, conservative surgery, or the selective administration of postoperative chemotherapy, will be realized for locally-advanced rectal cancer patients based on their response to preoperative chemoradiotherapy.

Abstract PDF

Purpose

The purpose of this study was to assess the risk factors for repeated abdominal surgery in Crohn's disease (CD) patients after the first abdominal surgery. Prior studies have tried to identify the risk factors for postoperative recurrence in CD patients, but the results of the studies have been inconsistent. Furthermore, few data on the risk factors for repeated abdominal surgery are available.

Methods

Clinical data on CD patients who underwent abdominal surgery from January 2000 to December 2009 were collected from seventeen university hospitals and one colorectal clinic. Data from a total of 708 patients were analyzed to find the risk factors for repeated abdominal surgery in CD patients. The mean follow-up period was 72 months.

Results

The risk of repeated abdominal surgery was 3 times higher in young patients (below 16 years old) than in older patients (odds ratio [OR], 3.056; 95% confidence interval [CI], 1.021 to 9.150); P = 0.046). Stricturing behavior at diagnosis was also a risk factor for repeated abdominal surgery (OR, 2.438; 95% CI, 1.144 to 5.196; P = 0.021). Among operative indications, only intra-abdominal abscess was associated with repeated abdominal surgery (OR, 2.393; 95% CI, 1.098 to 5.216; P = 0.028). Concerning type of operation, an ileostomy might be a risk factor for repeated abdominal surgery (OR, 11.437; 95% CI, 1.451 to 90.124; P = 0.021). Emergency surgery (OR, 4.994; 95% CI, 2.123 to 11.745; P < 0.001) and delayed diagnosis after surgery (OR, 2.339; 95% CI, 1.147 to 4.771; P = 0.019) also increased the risk of repeated abdominal surgery.

Conclusion

Young age (below 16 years), stricturing behavior, intra-abdominal abscess, emergency surgery, and delayed diagnosis after surgery were identified as possible risk factors for repeated abdominal surgery in CD patients.

Purpose

Treatment of descending perineal syndrome is focused on personal etiology and on improving symptoms. However, the etiology of increased perineal descent (PD) is unclear. Therefore, the aim of the present study was to evaluate factors associated with increased resting and dynamic PD in women.

Methods

From January 2004 to August 2010, defecographic findings in 201 female patients were reviewed retrospectively. Patient's age, surgical history, manometric results and defecographic findings were compared with resting and dynamic PD.

Results

Age (P < 0.01), number of vaginal deliveries (P < 0.01) and resting anorectal angle (P < 0.01) were correlated with increased resting PD. Also, findings of rectoceles (P < 0.05) and intussusceptions (P < 0.05) were significantly correlated with increased resting PD. On the other hand, increased dynamic PD was correlated with age (P < 0.05), resting anal pressure (P < 0.01) and sigmoidoceles (P < 0.05). No significant correlation existed between non-relaxing puborectalis, history of pelvic surgery and increased PD. Also, no significant differences in PD according to the symptoms were observed.

Conclusion

Increased number of vaginal deliveries and increased resting rectoanal angle are associated with increased resting PD whereas increased resting anal pressure is correlated with increased dynamic PD. Older age correlates with both resting and dynamic PD. Defecographic findings, such as rectoceles and intussusceptions, are associated with resting PD, and sigmoidoceles correlated with dynamic PD. These results can serve as foundational research for understanding the pathophysiology and causes of increasing PD in women better and for finding a fundamental method of treatment.

Abstract PDF

Purpose

Recently, an increase in well-differentiated rectal neuroendocrine tumors (WRNETs) has been noted. We aimed to evaluate transanal endoscopic microsurgery (TEM) for the treatment of WRNETs.

Methods

Between December 1995 and August 2009, 109 patients with WRNETs underwent TEM. TEM was performed for patients with tumors sizes of up to 20 mm and without a lymphadenopathy. These patients had been referred from other clinics after having been diagnosed with WRNETs by using a colonoscopic biopsy; they had undergone a failed endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) and exhibited an involved resection margin and remaining tumor after ESD or EMR, regardless of the distance from the anal verge. This study included 38 patients that had more than three years of follow-up.

Results

The mean age of the patients was 51.3 ± 11.9 years, the mean tumor size was 8.0 ± 3.9 mm, and no morbidity occurred. Thirty-five patients were asymptomatic. TEM was performed after a colonoscopic resection in 13 cases because of a positive resection margin, a residual tumor or a non-lifting lesion. Complete resections were performed in 37 patients; one patient with a positive margin was considered surgically complete. In one patient, liver metastasis and a recurrent mesorectal node occurred after five and 10 years, respectively.

Conclusion

TEM might provide an accessible and effective treatment either as an initial or as an adjunct after a colonoscopic resection for a WRNET.

Abstract PDF

Purpose

Preoperative chemoradiotherapy is now widely accepted to treat rectal cancer; however, the prognosis for rectal cancer patients during and after chemoradiotherapy must be determined. The aim of this study was to evaluate the serial serum carcinoembryonic antigen (s-CEA) samples in patients with rectal cancer who underwent radical surgery after concurrent chemoradiotherapy (CRT).

Methods

This study evaluated 236 patients with rectal cancer who received preoperative CRT followed by curative surgery between June 2005 and June 2010. We measured the patient's s-CEA levels pre-CRT, post-CRT and post-surgery. Patients were classified into four groups according to their s-CEA concentrations (group 1, high, high, high; group 2, high, high, normal; group 3, high, normal, normal; group 4, normal, normal, normal). We analyzed the clinicopathologic factors and the outcomes among these groups.

Results

Of the 236 patients, 12 were in group 1, 31 were in group 2, 67 were in group 3, and 126 were in group 4. The 3-year disease-free survival rate in group 1 was poorer than those in group 3 (P = 0.007) and group 4 (P < 0.001). In a univariate analysis, type of surgery, clinical N stage, pathologic T or N stage, lymphovascular invasion, perineural invasion, and CEA group were prognostic factors. A multivariate analysis revealed that type of surgery, pathologic T stage, and lymphovascular invasion were independent prognostic factors; however, no statistical significance was associated with the CEA group.

Conclusion

High pre-CRT, post-CRT, and post-surgery s-CEA levels in patients with rectal cancer were associated with high rates of systemic recurrence and poor survival. Therefore, patients with sustained high s-CEA levels during CRT require careful monitoring after surgery.

Abstract PDF

Purpose

In recent years, the incidence of early-stage colorectal cancer (CRC) has markedly increased in the population within the Republic of Korea. The aim of this study was to evaluate the clinicopathologic features of adenomatous polyps in TNM stage I CRC patients and in the general population.

Methods

Between March 2003 and September 2009, 168 patients with stage I CRC were enrolled in this study. In addition, the records of 4,315 members of the general population without CRC, as determined by colonoscopy during a health check-up, were reviewed.

Results

Of the 168 patients with stage I CRC, 68 (40.5%) had coexisting colorectal adenomatous polyps and of the 4,315 members of the general population, 1,112 (26.0%) had coexisting adenomatous polyps (P = 0.006). The prevalences of adenomatous polyp multiplicity in early CRC and in the general population were 32% and 15%, respectively (P = 0.023). Patients with coexisting adenomatous polyps had a higher frequency of tubulovillous or villous adenomas than members of the general population with polyps (7.5% vs. 2.0%, P = 0.037). Furthermore, a subgroup analysis showed that the occurrence (44% vs. 34%, P = 0.006) and the multiplicity (32% vs. 15%, P = 0.023) of adenomatous polyps were greater for T2 than T1 cancer.

Conclusion

The prevalence and the multiplicity of adenomatous polyps in TNM stage I CRC is higher than it is in the general population. The findings of this study suggest that depth of invasion of early stage CRC affects the prevalence and the number of adenomatous polyps in the remaining colon and rectum.

Abstract PDF

A myolipoma is an extremely rare benign neoplasm, occurring most frequently in adults in the deep soft tissue of the abdomen or retroperitoneum. We experienced a case of an anal myolipoma occurring in a 30-year-old woman, and it was surgically resected. To our knowledge, this is the first reported case of a myolipoma arising from the anus, so such a possibility needs to be considered in the differential diagnosis.
