Background Lymphocele and lymphorrhea are frequent complications after lymph node excision. Recurrent lymphoceles and intractable lymphorrhea are particularly difficult to treat conservatively. We describe the outcomes of four patients with recurrent lymphocele and nine patients with persistent lymphorrhea that were treated by supermicrosurgery. Methods Four patients with recurrent lymphoceles with a size between 7 and 21 cm and located in the groin (n = 1) or upper leg (n = 3), were referred for surgical treatment between 2013 and 2017 after unsuccessful conservative therapy. Nine patients with lymphorrhea from the groin (n = 7), scrotum (n = 1), or axilla (n = 1) after lymph node or lipoma excision were referred for surgical treatment. Of these, five patients presented with a drainage system and two had a lymphocutaneous fistula. Indocyanine green (ICG) lymphography was used to visualize the lymphatic flow toward the lymphocele, to detect ruptured lymph vessels causing lymphorrhea and for preoperative lymphatic mapping. Results All 13 patients were successfully treated by one or more (mean: 3, range 1–4) lymphaticovenous anastomoses without perioperative complications. The lymphoceles resolved in all four patients, and no recurrence was recorded during follow‐up. The lymphorrhea was cured in all patients by means of lymphaticovenous anastomosis performed distal to the site of leakage. No recurrence was observed during follow‐up. The patency of the lymphaticovenous anastomosis was confirmed intraoperatively by means of ICG lymphography in all cases. Conclusion Lymphaticovenous anastomosis is a minimally invasive and effective procedure for the treatment of recurrent lymphocele and persistent lymphorrhea.

A newborn infant with patent omphalomesenteric duct (POMD), who presented faecal umbilical discharge, was treated with a semicircular periumbilical incision up to the abdominal cavity. The omphalomesenteric duct was followed up to the junction with the small intestine and there resected. The abdominal wall was closed without resection of the umbilicus.
