Laparoscopic treatment of retroperitoneal cystic mesothelioma. Two cases reported

Retroperitoneal cystic mesothelioma is a very rare lesion. The pathogeny is unclear and establishing a preoperative diagnosis versus others retroperitoneal cystic lesions is difficult.Thus, with increasing experience in laparoscopic retroperitoneal surgery, the use of this approach for exploration of a retroperitoneal mass of unknown origin may provide an alternative to classic open surgery and all the benefits of laparoscopy. We present two cases treated laparoscopycally and review the literature.     

Indications for body MRI Part II: retroperitoneum, intestines and pelvis

In this article an overview is given of the present knowledge of whole body MRI, MRI of the retroperitoneum, intestines and pelvis. Recommendations are based on current literature and clinical applications in daily routine focusing on efficacy rather than cost considerations. The contribution and complementary role of MRI relative to those of its competing modalities was the most important endpoint assessed. Perfusion and functional information, as well as specific contrast agents in the area of the pelvis are still considered research indications.     

腹膜后神经节细胞瘤的CT诊断与文献复习

目的分析腹膜后神经节细胞瘤的CT表现。方法回顾分析8例经手术证实的腹膜后神经节细胞瘤CT表现。结果8例病灶呈类圆形或卵圆形,平扫呈低密度肿块,密度均匀,边界均较清晰,增强后动脉期8例病灶均无明显强化,静脉期轻度强化3例,无明显强化5例。结论明确腹膜后神经节细胞瘤的CT特征有助于对腹膜后肿瘤的准确诊断和鉴别。     

NOTES new frontier: Natural orifice approach to retroperitoneal disease

AIM: To develop a pure transvaginal access to the retroperitoneum, that is simple, reproducible and uses endoscopic material available on the market.METHODS: From February 2008 to April 2009, 31 pigs were operated on, with 17 as an acute experiment and 14 with a survival protocol. The animals were placed in a supine position and a 12-mm double-channel endoscope (Karl Storz™, Tuttlingen) was used for vision and dissection. During the same time period, the access experiment was reproduced on 3 human cadavers using material similar to that used in the animal model.RESULTS: In the animal model, 37 interventions were done on the kidney, adrenal gland and pancreas. The mean time to fashion the access was 10 min (range 5 to 20 min). No intraoperative death was observed. Two major (5%) intraoperative complications occurred: one hemorrhage on the aorta and one tearing of the right renal vein. Peritoneal laceration was encountered in 5 cases without impairing the planned task. In the survival group, good clinical outcome was observed at a mean follow-up of 3 wk (range 2 to 6 wk). In the 3 cadavers, access was performed correctly. The mean time to fashion the access was 52 min (range 40 to 60 min). All the anatomical landmarks described in the pig model were clearly identified in the same sequence.CONCLUSION: A retroperitoneal natural orifice translumenal surgical transvaginal approach is feasible in both animal and human models and allows performance of a large panel of interventions.     

经后腹腔途径腹腔镜下肾癌根治术的临床效果

目的观察和评价临床上经后腹腔途径腹腔镜下肾癌根治术的效果以及安全性。方法以该院收治的50例肾癌患者为研究对象,患者均上经后腹腔途径腹腔镜下肾癌根治术治疗,回顾性分析患者的临床资料。结果 50例手术均成功,手术时间80~150 min;出血量50~150 mL;术后患者肠功能恢复时间为2~3 d,患者住院时间为7~14 d;对患者进行为期3个月~1年的随访,在此期间未出现复发以及转移。结论经后腹腔途径腹腔镜下肾癌根治术是着一种微创手术,安全有效。     

Portosystemic shunt on CT during arterial portography: prevalence in patients with and without liver cirrhosis

Background To review various portosystemic shunts (PS) and to evaluate their prevalence by CT during arterial portography (CTAP) using a multidetector-row CT (MDCT). Methods CTAP of 116 patients (liver cirrhosis 70 patients, non-liver cirrhosis 46 patients) was retrospectively reviewed. CTAP was performed with the catheter placed in the superior mesenteric artery using MDCT. Axial CT images of 0.625- and 3.75- or 2.5-mm thickness were obtained. Multiplanar reformation images and maximum intensity projection images were subjected to review. Results A part of the veins in the ileocecal region drained into the right renal vein or the inferior vena cava (IVC) via the right gonadal vein in 57 patients (81%). A part of the veins of the ascending colon drained via the right renal capsular vein into the IVC in 37 patients (53%). In 46 patients without liver cirrhosis, the right gonadal and right renal capsular veins were opacified on CTAP in 22 patients (48%) and 20 patients (43%), respectively. Conclusions Portosystemic shunts in retroperitoneum were frequently recognized on CTAP images in patients with liver cirrhosis. The right gonadal vein and the right renal capsular vein were the most frequent routes of the portosystemic shunts. They may exist in physiological condition.     

25例经腹膜后间隙腹腔镜下肾囊肿去顶术手术配合

目的探讨腹膜后间隙腹腔镜下肾囊肿去顶术的手术配合。方法对2008年11月至2009年8月完成的25例经腹膜后间隙腹腔镜下肾囊肿去顶术患者手术配合进行总结。结果全部手术均顺利完成。结论微创手术的广泛开展给手术室护士提出了新的挑战,必须不断学习新知识新技能,同时必须配备专职护士,确保手术配合成功。
