This comparative clinical study suggests that LC results in less adhesion formation, either on the operative or at the trocar entry sites, than open cholecystectomy.
In 55 patients with benign or malignant neoplasias of the large bowel, serum carcinoembryonic antigen (CEA), C-reactive protein (CRP), a,-antitrypsin (AAT), alacid glycoprotein (AAG) levels, and the percentage of serum protein electrophoretic components were measured. Statistical analysis showed significant correlations between serum CEA, CRP, AAG, and AAT levels and the percentage of serum 8-globulins with the stage of the disease. Multivariate discriminant analysis gave a final prognostic model that included serum CEA, CRP, and AAT levels and the percentage of the serum &globulins with a significance of P < 0.000001. The authors conclude that the serum acute-phase protein levels, in combination with serum CEA concentrations, have a definite role in the preoperative staging of large bowel cancer.
Imiquimod has been demonstrated to be rather effective in patients with anal as well as perianal high-grade squamous intraepithelial lesions (HSILs). Nevertheless, until now the intra-anal use of imiquimod has been considered off-label. The aim of this study is to review the clinical evidence related to the intra-anal use of imiquimod in the treatment of human papillomavirus-related anal lesions. A systematic search in PubMed and Scopus was performed. In total, 422 patients were included. The most common referred comorbidity was HIV infection (281 patients, 66.6%). The principal clinical entities, which were treated with intra-anal imiquimod, were HSILs. The most frequent formulation was self-applied imiquimod cream. In the HSIL group, there was complete healing in 74 patients (35%) and partial in 44 patients (20.9%), while in the wart group, there was complete healing in 128 patients (67%). Recurrence of HSIL was present in 19 patients (15%), while in cases with warts recurrence was present in 38 patients (19.8%). The most common adverse events were pain, itching, and burning sensation. In conclusion, the adverse effects associated with the intra-anal use of imiquimod seem to be minor. The present clinical evidence suggests that imiquimod may be proposed as effective, safe, and relatively well tolerated treatment.
Sphincter trauma after anorectal surgery is usually asymptomatic. Frequency of trauma cannot be established with the clinical examination only. The frequency of operative sphincter defects and their correlation with disorders of continence was evaluated with the endoanal ultrasound. This study includes 123 subjects who had undergone anorectal surgery in the past and were examined with endoanal ultrasound for various indications such as continence disorders, recurrent fistula, idiopathic perineal pain, or simple postoperative follow-up. No subjects had isolated external anal sphincter defects. Nineteen of 123 patients (15%) had minor or major continence disorders, 55 patients (45%) had no sphincter defects, 42 (34%) had only internal anal sphincter (IAS) defects, and 26 (21%) had simultaneously external and internal anal sphincter (EAS) defects. The incidence of IAS and EAS trauma after Milligan-Morgan hemorrhoidectomy was 1/18 (5.5%) and 0/18 respectively; after fistula repair, 24/42 (57%) and 12/42 (29%); and after anal dilatation, 13/17 (76%) and 4/17 (24%). Sixteen of 26 patients (62%) with EAS trauma and 51/68 patients (75%) with IAS trauma did not report any disorders of continence. In patients with two or more operations, the frequency of IAS trauma was 74%, 30% for EAS trauma, and 26% for continence disorders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
