Abstract：
We report the case details of a 65-year-old Japanese man with an omental abscess that was discovered 43 days after he underwent a laparoscopic proximal gastrectomy for gastric cancer. His chief complaint was mild abdominal pain that had persisted for several days. The abscess was diagnosed as a rare postoperative complication. We hesitated to perform a reoperation given the invasiveness of general anesthesia and surgery, plus the possibility of postoperative adhesions and because the patient\'s general condition was stable and he had only mild abdominal pain. Percutaneous drainage using a 10.2-F catheter was performed with the patient under conscious sedation and computed tomography-fluoroscopy guidance, with no complications. After the procedure, the size of the abscess cavity was remarkably reduced, and 23 days later the catheter was withdrawn.
摘要：
我们报告了一名65岁的日本男子患有网膜脓肿的病例细节，该病例是在接受腹腔镜近端胃癌切除术43天后发现的。他的主诉是轻度腹痛，持续了几天。脓肿被诊断为罕见的术后并发症。考虑到全身麻醉和手术的侵入性，我们犹豫是否进行再次手术，再加上术后粘连的可能性，因为患者的一般情况稳定，他只有轻微的腹痛。患者在清醒镇静和计算机断层扫描透视指导下使用10.2-F导管进行经皮引流。没有并发症。手术后,脓肿腔的大小明显缩小，23天后，导管被撤回。
