Motor function was investigated by constant perfusion manometry in the Roux limb of ten patients who had undergone total gastrectomy and Roux-en-Y anastomosis. Results showed that in the fasting state, the migrating motor complex (MMC) was comletely absent, retrograde in direction or bursts of nonphasic pressure activity. Reduced motor activity patterns occurred after the meal in some patients. Four patients failed to convert fasting state into the feeding state. Total gastrectomy with Roux-en-Y anastomoses provakes a relatively severe distubance in motor function, which could contribute to postoperative upper abdominal distress.
目的 总结原发性腹膜后脂肪肉瘤（primary retroperitoneal liposarcoma，PRL）的临床病理特征、诊断及治疗方法。 方法 回顾性分析经手术和活检证实的23例PRL患者的临床病理资料。结果 首发症状及体征表现为腹部肿块（91.3%，21/23），腹胀（56.5%，13/23）及腹痛（30.4%，7/23）。B超及CT的定位诊断准确率分别为66.7%（12/18）和85.7%（12/14）。首次手术肿瘤完整切除16例（69.6%），其中8例联合脏器切除； 部分切除3例（13.0%）； 仅行活检4例（17.4%）。PRL肿瘤完整切除术后复发率为75.0%（12/16）,该12例中再次手术8例（66.7%）可完全切除肿瘤。结论 CT是诊断PRL的重要手段，优于B超； 手术以完整切除肿瘤为主，对侵犯脏器者采用累及脏器一并切除； 术后复发者可再次手术。
