A retrospective review of 409 patients with bile duct obstruction (373 undergoing definitive surgery and 36 undergoing laparotomy only) identified 27 patients who developed significant postoperative gastrointestinal bleeding necessitating transfusion. All 27 had undergone a definitive procedure to relieve obstruction. Nineteen patients required blood replacement of six or more units. The majority of patients bled in the first four postoperative days. The sites of hemorrhage were identified in 25 patients, gastric erosions being the most common lesions detected. Thirteen of the 27 patients died, seven due to overwhelming blood loss despite massive transfusion. Eight of the 27 required an operation because of bleeding. An analysis of the relationship between preoperative factors and gastrointestinal bleeding identified three factors that were independently associated with this complication. These were: 1) an initial hematocrit of 30% or less; 2) an initial leukocyte count in excess of 10 X 10(9)/l; and 3) a malignant obstructing lesion. Patients with two or all three of these factors were identified as being at very high risk of developing postoperative gastrointestinal hemorrhage. Bleeding into the upper gastrointestinal tract has been confirmed to be a major problem in the surgical management of patients with obstructive jaundice. Further studies of the etiology and prevention of this complication are indicated.
对409例胆管梗阻患者(373例行根治性手术,36例仅行剖腹手术)进行回顾性研究,发现27例患者术后发生严重胃肠道出血,需要输血。所有27例患者均接受了缓解梗阻的确定性手术。19例患者需要输注6个或更多单位的血液。大多数患者在术后头4天出血。25例患者确定了出血部位,胃糜烂是最常见的病变。27例患者中有13例死亡,7例因尽管大量输血仍失血过多死亡。27例患者中有8例因出血需要手术。对术前因素与胃肠道出血之间关系的分析确定了与该并发症独立相关的三个因素。这些因素是:1)初始血细胞比容为30%或更低;2)初始白细胞计数超过10×10⁹/L;3)恶性梗阻性病变。具有其中两个或全部三个因素的患者被确定为发生术后胃肠道出血的风险非常高。上消化道出血已被证实是梗阻性黄疸患者手术治疗中的一个主要问题。需要对该并发症的病因和预防进行进一步研究。
