Treatment-Based Three-Dimensional Classification and Management of Anorectal Infections.

This article provides a current overview on clinical anatomy, pathophysiology, workup and surgical management of anorectal abscesses. Based on the three-dimensional nature of anorectal abscesses, a novel treatment-based classification is proposed. It examines the basis of a philosophic shift from simple drainage to concomitant definitive treatment of abscesses and their underlying primary fistulous trajectories. Complications are discussed specifically in this context.

The standardized vascular clinic: an alternative to the traditional ambulatory setting.

PURPOSE: To investigate the effectiveness of a standardized vascular clinic (SVC) in teaching diagnostic and management skills for common vascular problems, as compared with that of the traditional ambulatory setting. METHODS: Third-year medical students participating in the required surgical clerkship participated in this study. Students were randomly assigned to attend either a 4-hour SVC experience (group 1, n = 64) or a 4-hour traditional ambulatory experience (group 2, n = 60). Students completed a satisfaction rating scale and a preencounter and postencounter self-efficacy rating scale at the end of the experience. Student t tests were used to compare the groups in the areas of knowledge acquisition, problem solving, clinical skills and satisfaction with the encounter. Analysis of covariance was used to compare the change between pre and post self-efficacy ratings. RESULTS: Students in group 1 performed significantly higher than students in group 2 in the areas of problem solving, clinical skills, and student satisfaction. They also demonstrated a higher level of confidence in their vascular skills than students assigned to the traditional setting. CONCLUSION: The SVC may be more effective in teaching problem-solving and clinical skills. It also may promote more student satisfaction with the experience and confidence in clinical skills than the traditional ambulatory setting.

Selective management of hepatic adenomas.

Hepatic adenomas are uncommon hepatic neoplasms that may be identified after life-threatening hemorrhage, or as an incidental radiologic finding. The incidence of malignant transformation is unknown, and the correct treatment strategy is unclear. We examined our 10-year experience in the management of 12 patients with hepatic adenomas. Eleven adults (mean age of 37.6 years) and one 3-month-old were identified. Nine of 10 adult females (90%) were taking a hormonal preparation at the time of diagnosis. Four patients with tumor sizes of 1.0 to 4.0 cm were observed after cessation of oral contraceptives. Four patients with lesions of 5.5 to 13 cm underwent surgical resection. Three had malignant transformation, and two of the three had increased Alpha-fetoprotein levels. Four patients presented with acute hemorrhage and were treated initially by hepatic arterial embolization. We conclude that management of adenomas should be individualized based on their size and mode of presentation. Patients with lesions less than 5 cm and normal alpha-fetoprotein can be safely observed off oral contraceptives and followed by radiologic imaging. Lesions >5 cm should be considered for surgical resection due to the risk of malignancy. Hepatic arterial embolization is a new approach for acute hemorrhage.
