Feasibility of Single-Port Laparoscopic Lymph Node Biopsy for Intra-Abdominal Lymphoma: A Case Series

Description

Background: Laparoscopic lymph node biopsy through a multi-port access (MPLB) is a well-established technique for intra-abdominal lymphoma diagnosis. The aim of the current study is to assess the feasibility and the diagnostic accuracy of the single-port laparoscopic lymph node biopsy (SPLB) in intra-abdominal lymphoma. Materials and Methods: Between October 2016 and February 2019, 15 patients underwent SPLB to rule out or to follow the progression of a lymphoma. The clinical outcome and the pathology reports were analyzed retrospectively. Results: SPLB was completed laparoscopically in all cases. The total number of biopsies performed for each procedure was sometimes multiple (median: 2; range: 1-3). Duration of surgery was 85 ± 32 minutes (range: 75-105 minutes). Length of hospitalization was 1.8 ± 0.7 days (range: 1-3 days). No major postoperative complications occurred. A cutaneous infection managed conservatively was observed in a patient. In 10 patients, SPLB was used to establish a diagnosis whereas in 5 patients it was performed to follow a progression of a lymphoproliferative disease. In 93.3% of the cases, SPLB achieved the correct diagnosis and subsequent therapeutic decisions. Conclusion: SPLB has shown good procedure and postoperative outcomes as well as a high diagnostic yield, comparable to literature data on traditional MPLB. Therefore, our results show that this approach is safe and effective and can be an equally valid option to MPLB to obtain a diagnosis or to follow the progression of a lymphoproliferative disease. Further studies are necessary to support these results before its widespread adoption.
