Graphical Abstract Abstract PDF Supplementary Material: Purpose
Blood transfusion is one of the most common procedures used to treat anemia in colorectal surgery. Despite controversy regarding the adverse effects of blood products, surgeons have maintained standards for administering blood transfusions. However, this trend was restrictive during the COVID-19 pandemic because of a shortage of blood products. In this study, we conducted an analysis to investigate whether the restriction of blood transfusions affected postoperative surgical outcomes.
Methods
Medical records of 318 patients who underwent surgery for colon and rectal cancer at Ewha Womans University Mokdong Hospital between June 2018 and March 2022 were reviewed retrospectively. The surgical outcomes between the liberal and restrictive transfusion strategies in pre– and post–COVID-19 groups were analyzed.
Results
In univariate analysis, postoperative transfusion was associated with infectious complications (odds ratio [OR], 1.705; 95% confidence interval [CI], 1.015–2.865; P=0.044). However, postoperative transfusion was not an independent risk factor for the development of infectious complications in multivariate analysis (OR, 1.305; 95% CI, 0.749–2.274; P=0.348). In subgroup analysis, there was no significant association between infectious complications and the hemoglobin threshold level for the administration of a transfusion (OR, 1.249; 95% CI, 0.928–1.682; P=0.142).
Conclusion
During colorectal surgery, the decision to perform a blood transfusion is an important step in ensuring favorable surgical outcomes. According to the results of this study, restrictive transfusion is sufficient for favorable surgical outcomes compared with liberal transfusion. Therefore, modification of guidelines is suggested to minimize unnecessary transfusion-related side effects and prevent the overuse of blood products.

Purpose
Obesity has been known to contribute to technical difficulties in surgery. Until now, body mass index (BMI) has been used to measure obesity. However, there are reports that BMI does not always correspond to the visceral fat. Recently, bioelectrical impedance analysis (BIA) has been used for body composition analysis. This study aimed to evaluate the usefulness of the body composition index obtained using a BIA device in predicting short-term postoperative outcomes.
Methods
Data of patients who underwent elective major colorectal surgery using minimally invasive techniques were reviewed retrospectively. Body composition status was recorded using a commercial BIA device the day before surgery. The relationship between BMI, body composition index, and short-term postoperative outcomes, including operative time, was analyzed.
Results
Sixty-six patients were enrolled in this study. In the correlation analysis, positive correlation was observed between BMI and body composition index. BMI and body composition index were not associated with short-term postoperative outcomes. Percent body fat (odds ratio, 4.226; 95% confidence interval [CI], 1.064–16.780; P=0.041) was found to be a statistically significant factor of prolonged operative time in the multivariate analysis. Correlation analysis showed that body fat mass was related to prolonged operative time (correlation coefficients, 0.245; P=0.048). In the area under curve analysis, body fat mass showed a statistically significant predictive probability for prolonged operative time (body fat mass: area, 0.662; 95% CI, 0.531–0.764; P=0.024).
Conclusion
The body composition index can be used as a predictive marker for prolonged operative time. Further studies are needed to determine its usefulness.

Abstract PDF

Purpose

Lymph-node metastasis is considered as critical prognostic factor in colorectal cancer. A preoperative evaluation of lymph-node metastasis can also help to determine the range of distant lymph node dissection. However, the reliability of ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in the detection of lymph-node metastasis is not fully known.

Methods

The medical records of 433 patients diagnosed with colorectal cancer were reviewed retrospectively. FDG-PET/CT and CT were performed on all patients. Lymph nodes were classified into regional and distant lymph nodes according to the American Joint Committee on Cancer (AJCC) Cancer Staging Manual, 7th edition.

Results

The patients included 231 males (53.3%) and 202 females (46.7%), with a mean age of 64.7 ± 19.0 years. For regional lymph nodes, the sensitivity of FDG-PET/CT was lower than that of CT (57.1% vs. 73.5%, P < 0.001). For distant lymph nodes, the sensitivity of FDG-PET/CT was higher than that of CT (64.7% vs. 52.9%, P = 0.012). The sensitivity of FDG-PET/CT for regional lymph nodes was higher in patients with larger primary tumors. The positivity of lymph-node metastasis for FDG-PET/CT was affected by carcinoembryonic antigen levels, tumor location, and cancer stage for regional lymph nodes and by age and cancer stage for distant lymph nodes (P < 0.05).

Conclusion

The sensitivity of FDG-PET/CT for regional lymph-node metastasis was not superior to that of CT. However, FDG-PET/CT provides helpful information for determining surgical plan especially in high risk patients group.

Abstract PDF

Purpose

In the metastatic process, interactions between circulating tumor cells (CTCs) and the extracellular matrix or surrounding cells are required. β₁-Integrin may mediate these interactions. The aim of this study was to investigate whether β₁-integrin is associated with the detection of CTCs in colorectal cancer.

Methods

We enrolled 30 patients with colorectal cancer (experimental group) and 30 patients with benign diseases (control group). Blood samples were obtained from each group, carcinoembryonic antigen (CEA) mRNA for CTCs marker and β₁-integrin mRNA levels were estimated by using reverse transcription-polymerase chain reaction, and the results were compared between the two groups. In the experimental group, preoperative results were compared with postoperative results for each marker. In addition, we analyzed the correlation between the expressions of β₁-integrin and CEA.

Results

CEA mRNA was detected more frequently in colorectal cancer patients than in control patients (P = 0.008). CEA mRNA was significantly reduced after surgery in the colorectal cancer patients (P = 0.032). β₁-Integrin mRNA was detected more in colorectal cancer patients than in the patients with benign diseases (P < 0.001). In colorectal cancer patients, expression of β₁-integrin mRNA was detected more for advanced-stage cancer than for early-stage cancer (P = 0.033) and was significantly decreased after surgery (P < 0.001). In addition, expression of β₁-integrin mRNA was significantly associated with that of CEA mRNA in colorectal cancer patients (P = 0.001).

Conclusion

In conclusion, β₁-integrin is a potential factor for forming a prognosis following surgical resection in colorectal cancer patients. β₁-Integrin may be a candidate for use as a marker for early detection of micrometastatic tumor cells and for monitoring the therapeutic response in colorectal cancer patients.

Abstract PDF

Diverticula are frequently seen in the sigmoid, descending, ascending and transverse colons whereas rectal diverticula are extremely rare. The stapled rectal mucosectomy for the treatment of a prolapsed hemorrhoid is less painful and has lower morbidity; therefore, it has been commonly used despite possible complications. This paper reports a case of a rectal diverticulum that developed after a procedure for prolapsed hemorrhoids (PPH). A 42-year-old man with a history of hemorrhoidectomies came to the hospital because of constipation. On sigmoidoscopy, a 2-cm-sized, feces-filled pocket was located just above the anorectal junction. After removal of the fecal material, a huge rectal diverticulum (-4 cm in diameter) was seen. Pelvic magnetic resonance imaging (MRI) confirmed the diagnosis of rectal diverticulum outpouching through the muscular layer of the intestine in a left posterolateral direction. The patient was discharged without complication after a transanal diverticulectomy had been performed, and the direct rectal wall had been repaired.

Abstract PDF

Purpose

Adjuvant chemotherapy is routinely recommended for locally advanced colorectal cancer (CRC). There are very few data for the optimal starting date of adjuvant chemotherapy after the surgery. This study aimed to evaluate the effectiveness of earlier adoption of adjuvant chemotherapy after curative surgery for stage III CRC.

Methods

In this study, 159 patients with stage III CRC, who had undergone a curative resection, were enrolled retrospectively. Patients were categorized into 3 groups representing different timings to initiate the chemotherapy; less than 2 weeks (group 1), 3 to 4 weeks (group 2), and more than 5 weeks (group 3). The overall survival rate (OS) and the relapse-free survival rate (RFS) were analyzed to evaluate the effectiveness of adjuvant chemotherapy.

Results

The 5-year OSs of the patients were 73.7% in group 1, 67.0% in group 2, and 55.2% in group 3. The 5-year RFSs of the patients were 48.8% in group 1, 64.7% in group 2, and 57.1% in group 3. There were no significant differences in either the OS or the RFS (P = 0.200, P = 0.405).

Conclusion

Starting chemotherapy earlier than 6 weeks after surgery does not show any significant difference. Thus, although adjuvant chemotherapy should preferably begin within 6 weeks, the starting date should not necessarily be hastened, and the patient's general condition should be taken into consideration.

Abstract PDF

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

Doppler-guided hemorrhoidal artery ligation and recto-anal repair (DG-HAL & RAR) is known for low recurrence, high patient satisfaction, and less postoperative pain. The purpose of this study is to analyze the 1-year follow-up results in patients who underwent a DG-HAL & RAR and to establish the benefits of the procedure.

Methods

Among the hemorrhoid patients who were admitted to our hospital from March 2008 to May 2010 and who underwent a DG-HAL & RAR, 97 patients who were followed up for a year were investigated. Recurrence, complications, admission period, difference in preoperative and postoperative pain, operation time, and time to return to daily activities were investigated.

Results

The average admission period was 1.6 ± 1.1 days. Pain at postoperative day 7 showed no significant difference from preoperative pain (P > 0.05). The operation time was 34.0 ± 7.3 minutes on average, and return to daily activities was timed at 2.3 ± 2.0 days postoperatively. At the one year follow-up, no serious complications were noted, and preoperative symptoms recurred only in 14 patients (14.4%).

Conclusion

In most patients with hemorrhoids, excluding those with severe prolapsed hemorrhoids, less pain, no serious complications, and good long-term outcome can be expected from a DG-HAL & RAR.

Purpose

The aim of this study is to evaluate long-term survival and prognostic factors for radio-frequency ablation (RFA) in colorectal liver metastases.

Methods

We retrospectively reviewed 35 colorectal liver metastases patients who underwent RFA between 2004 and 2008. We analyzed survival after RFA and prognostic factors for survival.

Results

Of the 35 patients, 23 patients were male and 12 were female. Their mean age was 62.40 ± 12.52 years. Mean overall survival was 38.8 ± 4.6 months, and mean progression free survival was 19.9 ± 3.4 months. Three- and 5-year overall survival rates were 42.7 ± 0.1% and 26.0 ± 0.1%, respectively. Three- and 5-year progression-free survival rates were 19.6 ± 0.1% and 4.9 ± 0.04%, respectively. Overall survival and progression-free survival were significantly improved in male and in patients with carcinoembryonic antigen (CEA) ≤ 100 ng/mL, carbohydrate antigen (CA) 19-9 ≤ 100 ng/mL, absence of extrahepatic disease, and a unilobar hepatic lesion. In addition, progression-free survival was improved in patients with a solitary hepatic lesion. On the multivariate analysis, significant survival factors were the absence of extrahepatic disease and the presence of a unilobar hepatic lesion.

Conclusion

RFA for colorectal liver metastases is an effective treatment option in male patients and in patients with CEA or CA19-9 ≤ 100, absence of extrahepatic disease, a solitary hepatic lesion, and a unilobar hepatic lesion.

Abstract PDF

Purpose

The epidermal growth factor receptor (EGFR) plays an important role in tumorigenesis and tumor progression of colorectal cancer and leads to the activation of intracellular signaling pathways. The use of anti-EGFR-targeted therapy has increased for patients with colorectal cancer, but patients with EGFR mutations will be resistant to anti-EGFR-targeted therapy. The identification of gene mutations is critical in cancer treatment; therefore, the aim of this study is to investigate the incidences of EGFR mutations in colorectal cancer patients in Korea.

Methods

We retrospectively reviewed 58 colorectal cancer patients who underwent surgery between 2003 and 2006. We analyzed their EGFR mutations in four loci by DNA sequencing. In addition, we analyzed the correlation between the presence of EGFR mutation and patients' clinicopathologic features.

Results

Of the 58 patients, 35 patients were male and 23 were female. Their mean age was 63.28 ± 11.18 years. Two patients (3.45%) were diagnosed as stage Tis, 7 patients (12.07%) as stage I, 24 patients (41.38%) as stage II, 20 patients (34.48%) as stage III, and 5 patients (8.62%) as stage IV. As a result of mutational analysis, EGFR mutations on exon 20 were detected in 13 patients (22.41%, G→A transitions). No EGFR mutations were detected on exons 18, 19, and 21. EGFR mutation was increased in the earlier stage and in the absence of lymph node metastasis (P = 0.028).

Conclusion

The incidence of EGFR mutation in Korean colorectal cancer patients is 22.41%. In addition, EGFR mutation was significantly increased in the earlier stage and in the absence of lymph node metastasis.
