Effect of endoscopic retrograde cholangiopancreatography combined with laparoscopy and choledochoscopy on the treatment of Mirizzi syndrome / 中华医学杂志(英文版)

ABSTRACT

<p><b>BACKGROUND</b>Mirizzi syndrome is often difficult to diagnose before surgery, and is often accompanied by extensive adhesions in the cystohepatic (Calot's) triangle and the difficulty of separating tissue can lead to bile duct injury and other intraoperative and postoperative complications. The aim of this study is to investigate minimally invasive means of treating different types of Mirizzi syndrome.</p><p><b>METHODS</b>Fifty-four patients diagnosed with Mirizzi syndrome were enrolled between July 2004 and May 2012. The diagnosis was further refined according to the Csendes classification. Twenty-seven patients were treated with a combination of endoscopic retrograde cholangiopancreatography (ERCP), laparoscopy, and choledochoscopy (tripartite approach group); type I in 16 cases, type II five cases, and type III in six cases. Twenty-seven patients were treated with laparotomy (routine approach group); type I in 19 cases, type II in six cases, and type III in two cases. The operation time, blood loss during operation, initiation of intake time of food, postoperative complications, and hospital stays were compared between two groups.</p><p><b>RESULTS</b>All patients were successfully cured in surgical operation. The operation time was (49.7 ± 27.5) minutes, blood loss during operation was (21.1 ± 15.9) ml, initiation of intake time of food was (6.3 ± 2.7) hours, postoperative complications were with two cases (7%, 2/27), and hospital stay was (6.7 ± 1.8) days in the tripartite approach group. In the routine approach group, the operation time was (85.1 ± 20.3) minutes, blood loss during operation was (150.3 ± 20.5) ml, initiation of intake time of food was (36.6 ± 10.3) hours, postoperative complications were with three cases (11%, 3/27), and hospital stay was (10.9 ± 3.4) days. Except for postoperative complications, there were significant differences in the operation time, blood loss during operation, initiation of intake time of food, and hospital stays between two groups (P < 0.05).</p><p><b>CONCLUSIONS</b>ERCP combined with laparoscopy and choledochoscopy is a safe and effective means of treating Mirizzi syndrome. The approach is minimally invasive and patients recover quickly requiring only brief hospitalization.</p>
