Bipolar vessel sealing system versus silk ligation of lymphatic vessels in renal transplant recipient lymphatic complications: a randomized controlled trial.

PURPOSE: This study was aimed to compare lymphatic complications of bipolar vessel sealing system with silk ligation of lymphatic vessels among renal transplant recipients. METHODS: This was a prospective randomized controlled trial done among 68 patients undergoing renal transplantation in Tribhuvan University Teaching Hospital. They were randomly assigned to either silk ligation or Enseal bipolar vessel sealing lymphatic dissection. Postoperative drain volume and duration of drain placement were measured in all patients. Ultrasound was used to find lymphocele formation in six and 12 weeks. RESULTS: Total of 30 patients in silk ligation group and 28 patients in bipolar vessel sealing group were analyzed. The baseline characteristics of the patients in each group were similar. Overall, lymphatic complications (either lymphorrhea or lymphocele formation) were in 16 cases (27.58%), 7 (25%) in the bipolar group, and 9 (30%) in the silk ligation group (p = 0.67). A total of 13 patients (22.41%) had lymphorrhea, 6 (21.4%) patients in the bipolar group, and 7 (23.3%) patients in the silk ligation group. Median drain volume was 415 ml (Q1 275 ml, Q3 675 ml) in the bipolar group and 542 ml (Q1 290, Q3 775) in silk group (p = 0.72). Median drain removal day was 5 in each bipolar and silk group with Q1 and Q3 being 5 days in each arm (p = 0.95). A total of five patients (8.62%) developed symptomatic lymphocele, two (7.1%) in the bipolar group, and three (10%) in the silk ligation group, but the difference was not statistically significant. In univariate analysis, double renal arteries in the donor's kidney (p = 0.03) and graft rejection (p = 0.04) were risk factors for the development of lymphatic complications. However, in multivariable analysis, these factors were not statistically significant. CONCLUSIONS: This study did not find any significant differences in lymphatic complications between bipolar vessel sealing system and silk ligation. However, large sample multi-centric studies should be done to add evidences on lymphatic complications differences between these two techniques.

Persistent Mullerian duct syndrome with transverse testicular ectopia: A case report.

Persistent Mullerian duct syndrome (PMDS) is a rare entity of internal male pseudohermaphroditism. Transverse testicular ectopia (TTE) is the condition in which one testis moves to the other side and both testes pass the same inguinal canal. The combination of PMDS with TTE is rarer. Here, we present a case a phenotype male with left inguinal hernia and right undescended testis. On exploration of left inguinal region, uterus like tissue with its tubal structures were found. Both testes were in same side, one in left inguinal region and the other in the left scrotum.
