Laparoscopic salpingectomy in tubal pregnancy: prospective randomized trial using endoloop versus electrocautery.

AIM Ectopic pregnancy is conventionally managed by laparoscopic salpingectomy. Electrocautery has been used widely to secure hemostasis during salpingectomy. However, this method is associated with a risk of thermal injury to the visceral organs. Endoloop, a pre-tied suture used in laparoscopic surgery may be an alternative treatment tool and its potential use in the management of ectopic pregnancy is explored here. Our study aims to compare the effectiveness of the endoloop technique to electrocautery during laparoscopic salpingectomy for tubal pregnancy. METHODS A prospective randomized controlled study was conducted over 24 months at the Hospital Universiti Kebangsaan Malaysia. One hundred and two patients with tubal pregnancy were randomized into two treatment groups: those treated with endoloop and those treated with electrocautery during laparoscopic salpingectomy. RESULTS The use of an endoloop was associated with a shorter operating time (48.85 min +/- 21.019 vs 61.14 min +/- 22.603, 95% CI -20.864 to -3.724), lower visual analog scores for postoperative pain at day 1 (2.02 +/- 0.960 vs 2.74 +/- 0.828, 95% CI -1.074 to -0.368) and day 7 (0.85 +/- 0.802 vs 1.44 +/- 0.837, 95% CI -0.916 to -0.272), and lesser total analgesia required by patients at day 7 after the operation (7.65 +/- 6.119 vs 15.32 +/- 8.326, 95% CI -10.529 to -4.804). There was no significant difference in the ability to secure hemostasis when both techniques were compared. Duration of hospitalization (2.37 days +/- 0.817 vs 2.34 days +/- 0.519, 95% CI -0.245 to -0.296) and interval from operation to discharge were similar. CONCLUSION The endoloop appeared to be as effective as electrocautery and is a safe alternative to electrocautery for laparoscopic salpingectomy in tubal pregnancy.
