The role of complete pelvic and para-aortic lymphadenectomy in early endometrial cancer remains controversial in gynecologic oncology. Sentinel lymph node detection is an alternative to assess lymphatic spread in several solid tumors. The authors review the literature related to the detection of sentinel lymph node in endometrial cancer, the techniques employed, and its results and feasibility. The authors review reported case series of endometrial cancer in which the sentinel lymph node biopsy was performed. A systematic literature review was conducted using the PubMed database. Different techniques were used considering lymphatic imaging mapping (colorimetric, isotopic, and fluorescence procedures) and injection site (subserous, hysteroscopic, and cervical). Detection rates of sentinel lymph node were heterogeneous, varying between 44 and 100 % with false-negative rates between 0 and 33 %. Although technically demanding, hysteroscopy approach was associated with the highest detection rate. The largest trials showed a good detection rate with cervical injection, a more reproducible procedure. The laparoscopic route improved the results. Immunohistochemistry staining improved the micrometastasis detection in sentinel lymph node. Cost-effectiveness of systematic lymphadenectomy compared with sentinel lymph node procedure and its value on adjuvant therapies as well as a standardized reproducible and reliable technique must be assessed.

Gynecologic surgery complications are varied and their frequency depends of surgery type and the patient´s comorbidities. Abdominal wall hematomas are uncommon cause of abdominal pain and it´s misdiagnosed. Most of abdominal wall hematomas are localized in rectus sheath and an oblique hematoma is a very rare condition with a few publications in literature.
