Laparoscopic splenectomy has become an important therapeutic option in the management of diverse hematologic disorders. However, the incidence of important complications, such as portal vein thrombosis, remains poorly understood. We set out to study the incidence of this complication over a 14-month period.
All adult patients who underwent laparoscopic splenectomy between July 2001 and April 2002 at McMaster University Medical Centre in Hamilton, Ont., were approached postoperatively and offered duplex ultrasonography of the portal vein to look for thrombosis.
During the study period 17 patients underwent laparoscopic splenectomy. Two patients declined to participate, and in 1 patient the ultrasonography was technically inadequate. Of the 14 remaining patients, 2 (14%) were found to have portal vein thrombosis. In 1 other patient, the investigation was suggestive, but not conclusive, of a clot in the portal system.
Portal vein thrombosis in this series was a relatively common complication of laparoscopic splenectomy. Further research is needed to confirm our findings.
腹腔镜脾切除术已成为治疗多种血液系统疾病的重要治疗选择。然而,诸如门静脉血栓形成等重要并发症的发生率仍了解甚少。我们着手研究这一并发症在14个月期间的发生率。
2001年7月至2002年4月期间在安大略省汉密尔顿市麦克马斯特大学医学中心接受腹腔镜脾切除术的所有成年患者在术后均接受随访,并接受门静脉双功超声检查以查找血栓形成。
在研究期间,17例患者接受了腹腔镜脾切除术。2例患者拒绝参与,1例患者的超声检查在技术上不充分。在其余14例患者中,2例(14%)被发现存在门静脉血栓形成。在另1例患者中,检查提示门静脉系统有血栓,但不能确诊。
本系列研究中,门静脉血栓形成是腹腔镜脾切除术相对常见的并发症。需要进一步研究以证实我们的发现。
