Original communicationInguinal node dissection for melanoma in the era of sentinel lymph node biopsy
Section snippets
Material and methods
Approval of the study was obtained from the University of Michigan Institutional Review Board. A retrospective review was performed of all patients who underwent an ILND between October 1997 and April 2006. Patients younger than 18 years of age were excluded, as were patients who underwent an ILND for histologies other than malignant melanoma. The clinical and pathologic data of the primary melanoma that were collected included age, sex, height, and body mass index (BMI). Breslow thickness
Results
Between October 1997 and April 2006, we identified 212 patients, 18 years of age and older, who underwent ILND for metastatic melanoma. The average age of the patients at the time of the ILND was 49.6 years (range, 17 to 92 years).
Of the 212 patients, 132 underwent ILND because of micrometastases detected on an SNL biopsy performed at the time of their local excision (Figure). A total of 80 patients underwent ILND because of clinically palpable disease. The majority of these patients, 49 (61%)
Conclusions
Inguinal groin dissection appears to carry an intrinsic risk of wound complication that is greater than that found in most other operations9, 10, 11, 12; reasons for this are multifactorial. Microorganisms in the groin area have been reported to be more numerous than the axilla and to harbor greater pathogenicity.13, 14 Thin flaps created in this area also are vulnerable to devascularization, leading to ischemia, wound edge necrosis, and creation of a portal of entry for infectious organisms.15

The present study found decreased risk of early complications in patients operated with CLND, which is in accordance with findings in a study of 212 patients,30 but in contrast to previous retrospective studies.30,31 The total number of removed lymph nodes was not significantly different for patients operated with CLND or TLND.
