ABSTRACT
BACKGROUND: The technique of the laparoscopic treatment of varicocele in children is described, and its outcome is discussed. METHODS: A total of 180 patients from 6 to 14 years of age were studied. All of them had left-sided varicocele; 10 of them were recurrences after treatment by other methods. Varicocele was diagnosed on physical examination and confirmed by Doppler ultrasonography. The laparoscopic procedure included obligatory dissection and preservation of the spermatic artery and tinted lymphatic vessels, followed by double ligation of the spermatic veins. RESULTS: There were no intraoperative or postoperative complications and only one case of recurrence (0.6%). CONCLUSION: The suggested technique for laparoscopic varix ligation is a highly effective and reliable method for the treatment of pediatric varicocele. It provides the minimal invasiveness of the approach, effective microsurgical quality of visualization, and dissection with guaranteed preservation of the spermatic artery and lymphatic vessels, along with very low rates of complication and recurrence.

PURPOSE: The technique and outcome of minimally invasive laparoscopic treatment of various forms of intussusception in children after ineffective attempt at conservative treatment are described. METHODS: Ninety-eight patients from 2 months to 11 years of age were analyzed. RESULTS: Suggested scheme of surgical treatment using laparoscopic technique was successful in 64 patients (65.3%), and conversion to open procedure occurred in 34 (34.7%). There was no mortality or intraoperative complications in our series. CONCLUSION: Practically every form of intussusception without bowel necrosis, including the most complex forms, can be reduced now using modern videolaparoscopic equipment and atraumatic instruments.

BACKGROUND: Posttransplant lymphoproliferative disorder (PTLD) has been observed with increasing frequency consequent to the availability of more effective and potent immunosuppression. Prior work suggested that a peripheral blood monitoring strategy detecting peripheral B lymphoproliferation was effective in the early diagnosis of PTLD among 7 of 179 (3.9%) consecutive transplant recipients. Each of those seven patients received at least one course of antithymocyte globulin, Minnesota antilymphocyte globulin, or OKT3 before developing PTLD. METHODS: To determine whether antiviral prophylaxis might reduce the incidence of PTLD, a subsequent group of 198 consecutive recipients received either ganciclovir or acyclovir during antilymphocyte antibody administration. When the donor or recipient were cytomegalovirus-seropositive, ganciclovir was given; acyclovir was used when both were cytomegalovirus-seronegative. Baseline and protocol posttransplant cell surface profiles were obtained using immunofluorescence and flow cytometry to detect T cells, lymphocyte activation markers, and the CD19 B cell antigen. RESULTS: Demographic factors, including the incidence of recipients more than 50 years of age, non-Caucasians, previous transplantation, and diabetes mellitus, were similar in both groups. Additionally, the number of patients receiving antilymphocyte preparations was similar. However, only one patient (0.5%) from the latter group who received preemptive antiviral therapy developed PTLD. Although elevations in CD19+ B cells preceded clinical PTLD among each of the seven earlier patients, evidence of peripheral B cell proliferation was not demonstrated for the sole patient from the latter group, which suggests a possible effect of antiviral therapy. CONCLUSIONS: Prophylactic antiviral therapy may reduce the sensitivity of peripheral monitoring for B lymphoproliferation, but the dramatic reduction in PTLD incidence strongly supports its use among transplant recipients at risk.
