Abstract
BACKGROUND: Lymphatic interventions have recently been increasingly used for treating lymphatic leak of the abdomen and pelvis. This retrospective case study series and systematic review evaluated the efficacy and safety of lymphatic interventions for the treatment of postoperative lymphatic leak of the abdomen and pelvis. METHODS: A total of 15 consecutive patients with postoperative lymphatic leak of the abdomen and pelvis treated with lymphatic interventions (i.e., diagnostic intranodal or pedal lymphangiography [LAG], i.e., potentially therapeutic or diagnostic LAG with intention to treat through embolization) at our institution were reviewed. The data of 72 patients from 13 relevant articles identified through a literature search of the MEDLINE/PubMed, EMBASE, and Cochrane databases were extracted. RESULTS: The data of 87 patients (mean age, 59 [range, 24-84] years) were pooled. The technical success rate of LAG (intranodal approach, 78.2% [68/87]; pedal approach, 21.8% [19/87]) was 97.7% (85/87; 95% confidence interval [CI], 91.5-99.9%). Of the 85 patients in whom technical success of LAG was achieved, data on clinical success were available for 47 patients (55.3%). The clinical success rate of LAG was 68.1% (32/47; 95% CI, 53.8-79.7%). Of the 85 patients in whom technical success of LAG was achieved, 38 (44.7%) underwent embolization. The technical success rate of embolization was 97.4% (37/38; 95% CI, 85.3-99.9%). The clinical success rate of embolization was 70.3% (26/37; 95% CI, 54.1-82.6%). Major complications did not occur. The overall primary and secondary clinical success rates were 65.5% (57/87; 95% CI, 55.0-74.7%) and 78.2% (68/87; 95% CI, 68.3-85.6%), respectively. CONCLUSIONS: Lymphatic interventions are safe and relatively effective adjunct to conservative therapy, with the primary and secondary clinical success rate of 65.5% and 78.2%, for postoperative lymphatic leak of the abdomen and pelvis.
