LigaSure hemorrhoidectomy with submucosal dissection is a safe, effective procedure for grade III and IV hemorrhoids. Patients derive greater short-term benefits: reduced intraoperative blood loss, operating time, and postoperative pain as well as earlier resumption of work or normal activity. Long-term follow-up with a larger number of patients is required to confirm the long-term results of this procedure.

The promising results of this study suggest that persistent presence of postoperative CTCs may be a crucial prognostic factor adjuvant to conventional tumor markers in CRC patients who have undergone curative resection. Identification of these high-risk patients of persistent CTCs positivity is important and thus could help to define patients for adjuvant therapy with this tumor entity.

Background: Low-molecular-weight fucoidan (LMF) is widely used as a food supplement for cancer patients. However, all of the studies are in vitro or were conducted using mice. Therefore, powerful clinical evidence for LMF use is relatively weak. This study aimed to evaluate the efficacy of LMF as a supplemental therapy to chemo-target agents in metastatic colorectal cancer (mCRC) patients. Methods: We conducted a prospective, randomized, double-blind, controlled trial to evaluate the efficacy of LMF as a supplemental therapy to chemotarget agents in patients with metastatic colorectal cancer (mCRC). Sixty eligible patients with mCRC were included. Finally, 54 patients were enrolled, of whom 28 were included in the study group and 26 in the control group. The primary endpoint was the disease control rate (DCR), and secondary endpoints included the overall response rate (ORR), progression-free survival (PFS), overall survival (OS), adverse effects (AEs), and quality of life (QOL). Results: The DCRs were 92.8% and 69.2% in the study and control groups, respectively (p = 0.026), in a median follow-up period of 11.5 months. The OS, PFS, ORR, AEs, and QOL did not significantly differ between the two groups. Conclusion: This is the first clinical trial evaluating the efficacy of LMF as a supplemental therapy in the management of patients with mCRC. The results indicate that LMF combined with chemotarget agents significantly improved the DCR.

Background: To evaluate the prognostic significance of pre- and postoperative serum carcinoembryonic antigen(CEA) levels in colorectal cancer (CRC) patients. Methods: 425 CRC patients underwent curative resection at our institution. Their pre- and postoperative serum CEA level was classified into two groups according to concentration: normal CEA (<5.0 ng/ml) and abnormal CEA (≧5.0 ng/ml). Results: Of all patients, abnormal pre- and postoperative serum CEA levels were observed in 181 (42.6%) and 48 (11.3%) patients, respectively. Abnormal preoperative serum CEA level was significantly correlated with the tumor located in the colon, the depth of tumor invasion, the status of lymph node metastasis, UICC stage, and the presence of postoperative relapse (p < 0.05). Concurrently, an abnormal postoperative serum CEA level was also prominently related to the above corresponding parameters (p < 0.05), except for the tumor location. Patients with a failed conversion of abnormal preoperative value to normal postoperative concentration were found to have the worst overall survival rate. Abnormal pre- and postoperative serum CEA levels were single independent predictors for survival and postoperative relapse, respectively. Conclusions: The identification of abnormal pre- and postoperative serum CEA levels may be useful in the auxiliary cancer prognosis or postoperative surveillance of CRC patients.

It is difficult to make an accurate diagnosis of abscess formation as the first evidence of colonic carcinoma pre-operatively. The one-stage resection of the lesion seems to be an acceptable treatment. For patients with intra-abdominal abscess, clinicians should be aware of this differential because it is easily ignored pre-operatively.

composite IVFE was comparable with conventional LCT/MCT IVFE in efficacy, safety, tolerance, and clinical outcomes in surgical GI tumor patients.

This study has revealed that the depth of invasion, the presence of vascular invasion, and number of examined lymph nodes, may prominently affect the prognosis of stage II CRC patients after radical resection. The increasing risk of postoperative relapse is proportionate to numbers of these three parameters.

BackgroundWe evaluated the clinicopathologic features and outcomes of Taiwanese patients with right-sided versus left-sided colon cancer according to various cancer stages.MethodsA total of 1095 patients with primary colorectal cancer (CRC) undergoing surgery at a single-institution were enrolled. We analyzed patient differences in terms of clinicopathologic features, overall survival (OS) and cancer-specific survival (CSS) of right- versus left-sided colon cancer.ResultsRight-sided colon cancers were noted in 249 (22.7 %) patients, and left-sided colon cancers were noted in 846 (77.3 %) patients. Right-sided colon cancers were found to be significantly larger (P = 0.003) and poorly differentiated (P < 0.001), while also exhibiting advanced depth of tumor invasion (P = 0.002) and advanced UICC/AJCC stage (P = 0.016). Patients with right-sided colon cancers had both poorer OS and CSS than those with left-sided colon cancers (P = 0.021 and 0.023, respectively). However, analysis by various stages revealed significant OS and CSS differences (P = 0.002 and 0.002, respectively) between right-sided and left-sided colon cancers only in stage III patients.ConclusionsThis study demonstrated poorer OS and CSS in patients with right-sided versus those with left-sided colon cancers, but significant differences were noted only in stage III patients.
