Splenic vessels thread ligature in laparoscopic splenectomy / 中华普通外科杂志

ABSTRACT

Objective To study the anatomy of splenic hilum blood vessels in order to thread ligature(endoligature)instead of using stapler during the process of laparoscopic splenectomy and to evaluate the prelimnary clinical results.Methods 41 children patients underwent laparoscopic splenectomy with this technique(endoligature)for various hematologic and autoimmune disorders,including 25 cases of hereditary spherocytosis,13 idiopathic thrombocytopenia purpura,and 3 hypersplenic granulocytopenia.The anatomy of splenic pedicle,the adjacent relation between splenic vessel and pancreas were detected by color Doppler ultrasonography preoperatively.The above-mentioned parameters were compared with that found intraoperatively.Results The relationships of splenic vessel and pancreas was of type Ⅰ in 24 cases and type Ⅱ in 17.In 31 cases,the major splenic blood vessels were ramified into branches 2 cm away from the hilum and in 10 it was within 2 cm as detected by preoperative ultrasonography.These characters were largerly identified by laparoscopic laparotomy,and in all the 41 cases laparoscopic splenectomy was successfully accomplished using this endoligature instead of vasculature stapler.There was no serious complication.The mean operating time was(114 ±31)min,the estimated blood loss was(51 ±23)ml.Conclusions Ultrasonography could identify the anatomic type of splenic vessel,and its relation with the pancreas.Endoligature in the management of splenic pedicles during laparoscopic splenectomy is safe and reliable.
