A case report and literature review of rectal lipoma.

RATIONALE: Colonic lipomas are uncommon benign submucosal adipose tumors that are usually asymptomatic. In principle, large lipomas can cause symptoms that require further treatment. Here, we report a case of prolapsed giant rectal lipoma and transanal mass resection. PATIENT CONCERNS: A 65-year-old male developed rectal mass prolapse with bloody stool for 1 day. DIAGNOSES: The pathological findings were rectal lipoma. INTERVENTION: After resection of the anal tumor, the patient postoperative symptoms quickly disappeared. OUTCOMES: No recurrence of the condition was observed after 6 months of follow-up after surgery. LESSONS: It is safe and feasible for us to perform transanal mass resection for giant rectal lipomas that protrude outside the anus.

Network meta-analysis of 8 types of traditional Chinese medicine injection combined with chemotherapy in colorectal cancer treatment.

OBJECTIVE: This study conducted a network meta-analysis to comprehensively compare the efficacy and safety of 8 types of traditional Chinese medicine injection combined with chemotherapy in colorectal cancer treatment. METHODS: We searched relevant previous studies from databases including Pubmed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Service System (SinMed), VIP, and Wanfang Database. The searched studies spanned from the inception of databases to December 2022. The included randomized controlled trials were screened; data were extracted; and bias risk was assessed. The network meta-analysis was performed using Revman 5.4 software, R software, and STATA software. RESULTS: Fifty randomized controlled studies were included, including 8 types of traditional Chinese medicine injection. The results showed that Aidi injection [OR 1.65,95%CI (1.33,2.05)], compound Kushenshen injection [OR 2.72,95%CI (2.12,3.51)], Kangai injection [OR 2.16,95%CI (1.56,3.02)], and Shenqi Fuzheng injection [OR 1.97,95%CI (1.24,3.15)] combined with chemotherapy in colorectal cancer treatment had a significantly higher objective response rate (p < 0.05) than single chemotherapy, and compound Kushen injection + chemotherapy [OR 2.72,95%CI (2.12,3.51)] regimen ranked the highest. The disease control rate of Aidi injection, Brucea javanica oil emulsion injection [OR 4.1,95%CI (1.74,10.43)], compound Kushen injection [OR 2.43,95%CI (1.73,3.44), Kangai injection[OR 2.31,95%CI (1.51,3.58)], Kanglaite injection[OR 3.18,95%CI (1.52,6.9)], and Shenqi Fuzheng injection[OR 2.6,95%CI (1.22,5.92)] combined with chemotherapy in the treatment of colorectal cancer was significantly improved (p < 0.05), and Brucea javanica oil emulsion injection + chemotherapy[OR 4.1,95%CI (1.74,10.43)] regimen ranked the highest. The incidence of leukopenia reduction in the treatment of colorectal cancer was significantly reduced by Aidi injection[OR 0.32,95%CI (0.24,0.43)], Brucea javanica oil emulsion injection [OR 0.34,95%CI (0.17,0.68)] compound Kushen injection [OR 0.27,95%CI (0.17,0.40)], Kangai injection [OR 0.23,95%CI (0.14,0.37)], and Kanglaite injection [OR 0.20,95%CI (0.09,0.45)] combined with chemotherapy (p < 0.05), and Kanglaite injection + chemotherapy [OR 0.20,95%CI (0.09,0.45)] regimen ranked the highest. Aidi injection [OR 0.48,95%CI (0.3,0.74)], Brucea javanica oil emulsion injection [OR 0.09,95%CI (0.01,0.43)], and Kangai injection [OR 0.47,95%CI (0.22,0.96)] combined with chemotherapy in the treatment of colorectal cancer significantly reduced the incidence of thrombocytopenia reduction (p < 0.05), and Brucea javanica oil emulsion injection + chemotherapy [OR 0.09,95%CI (0.01,0.43)] regimen ranked the highest. Aidi injection [OR 0.49,95%CI (0.32, 0.74)], Kangai injection [OR 0.26,95%CI (0.09,0.71)] combined with chemotherapy in the treatment of colorectal cancer significantly reduced the incidence of hemoglobin reduction (p < 0.05), and Kangai injection + chemotherapy [OR 0.26,95%CI (0.09,0.71)] regimen ranked the highest. Aidi injection [OR 0.38,95%CI (0.28,0.52)], compound Kushen injection [OR 0.23,95%CI (0.15,0.36)] and Kangai injection [OR 0.19,95%CI (0.12,0.30)] combined with chemotherapy in the treatment of colorectal cancer significantly reduced the incidence of nausea and vomiting (p < 0.05), and Kangai injection + chemotherapy[OR 0.19,95%CI (0.12,0.30)] regimen ranked the highest. Aidi injection [OR 0.51,95%CI (0.35,0.74)], compound Kushenshen injection [OR 0.27,95%CI (0.15,0.47)], and Kanglaite injection [OR 0.31,95%CI (0.13,0.69)] combined with chemotherapy in the treatment of colorectal cancer significantly reduced the incidence of abdominal pain and diarrhea (p < 0.05), and compound Kushen injection + chemotherapy [OR 0.27,95%CI (0.15,0.47)] regimen ranked the highest. CONCLUSION: Aidi injection, Brucea javanica oil emulsion injection, compound Kushen injection, Kangai injection, Shenqi Fuzheng injection, Kanglaite injection, Shenfu injection, and Xiaoaiping injection combined with chemotherapy functioned more effectively than single chemotherapy did in colorectal cancer treatment. Nevertheless, limited by the treatment quality and methodology of different intervention measures included in the study, this conclusion is expected to be scrutinized in higher-quality and rigorously designed randomized controlled trials.
