完全性胸腹腔内脏反位合并十二指肠壶腹周围癌一例报告与文献复习

目的总结完全性胸腹腔内脏反位合并十二指肠壶腹周围癌的临床诊治方法。方法报道2006年3月收治的1例极为罕见的完全性胸腹腔内脏反位合并十二指肠壶腹周围癌行胰十二指肠切除术的病例,并复习国内外相关文献。结果本例患者病理诊断为十二指肠乳头及壶腹部腺癌Ⅰ-Ⅱ级。术后1周胆红素降至正常;但2周后出现胃-空肠吻合输出袢粘连性不完全性梗阻,经内镜下置管、鼻饲、营养支持、针灸等处理,40d后痊愈出院。经检索,全球自1936-2006年间报道的全胸腹腔内脏反位合并恶性肿瘤的患者仅15例;其中只有5例全胸腹腔内脏反位合并胰头与壶腹周围癌的报道。结论完全性胸腹腔内脏反位合并肿瘤时,若无明显禁忌证,应同样予以积极的外科治疗,术中操作应注意完全相反的解剖学结构。     

Laparoscopic cholecystectomy for left-sided gallbladder (sinistroposition).

Transposition of the gallbladder to the left side without situs inversus viscerum is rare. These gallbladders are situated under the left lobe of the liver between Segment III and IV or on Segment III to the left of the falciform ligament. Because routine preoperative studies may not detect the anomaly, it may provide the surgeons with an unusual surprise during laparoscopy. Awareness of the unpredictable confluence of the cystic duct into the common bile duct and selective use of intraoperative cholangiography aid in the safe laparoscopic management of this unusual problem.     

Azoospermia in two brothers with Kartagener syndrome:a family history and diagnosis

0This article describes 2 infertile brothers of asoospermia equally associated with co-existing sinusitis,bronchiectasis,and situs inversus and their family history.These two cases were diagnosed as Kartagener syndrome(KS).The patients were not offspring of kin marriages but their family members with scattered bronchi-pulmouary infections were discovered.No one manifests azoospermia,dextrocardia or situs inversus in the paternal family ex-cept two cases reported.No abnormalities were found in their mother-side family.KS should be differentiated from Young's syndrome,cystic fibrosis(CF),and other diseases such as Kallmann's syndrome in male infertility clinic.     

Optic pit syndrome

In a study of 15 eyes with optic pits fluorescein angiography revealed that only pits associated with serous detachment of the macular retina showed fluorescence in the late venous phase, while the pits uncomplicated by detachment remained hypofluorescent throughout the test. This finding strongly supports the hypothesis that the subretinal fluid producing the macular detachment originates from leakage of vessels located in the floor of the pit. In addition a high incidence of anomalies was found to be associated with optic pits. Therefore the author suggests to call the association between optic pit and large optic disc, parapapillary chorioretinal changes, cilioretinal vessels, situs inversus and eventual other vessel abnormalities, the optic pit syndrome.     

决明子降血脂有效部位及其量效关系的实验研究

目的研究决明子降血脂的有效部位及其量效关系。方法选用CO超临界、系统溶媒(石油2醚、乙酸乙酯、70%乙醇、水)和水提醇沉的方法分别对决明子进行提取,观察各提取物对腹腔注射蛋黄乳液致高血脂症模型小鼠血清总胆固醇及甘油三酯的影响,初步明确决明子降血脂的有效活性部位,并对该有效部位进行量效关系的评定。结果决明子乙酸乙酯提取物和水提取物均有显著的降低血清总胆固醇和甘油三酯的作用,其中乙酸乙酯提取物的降脂效果优于水提取物,其在0.75～1.00g·kg-1·d-1时降脂效果最佳;决明子70%乙醇提取物和水提醇沉物虽也有一定的降血脂作用,但与对照组相比差异无统计学意义。结论决明子乙酸乙酯提取物为决明子降血脂的有效活性部位,其有效剂量范围在0.50～1.25g·kg-1·d-1之间。     

Two Cases of Mayer-Rokitansky-Kuster-Hauser Syndrome with Situs Inversus Totalis: Coincidence or Co-Existence?

Congenital absence of uterus and vagina, the Mayer-Rokitansky-Küster-Hauser Syndrome (MRKHS), results from defective müllerian duct development during female embryogenesis; it is the second most common cause of primary amenorrhea. Atypical forms of MRKHS (type B) represent a heterogeneous group of disorders with associated anomalies of other organ systems which frequently includes the renal and skeletal systems and several individually occurring malformations.We report two cases with MRKHS in which we diagnosed situs inversus totalis incidentally during radiologic examinations. Abdominal situs inversus describes the mirror-image arrangement of the intra-abdominal organs in the abdominal cavity and it is characterized by the presence of multiple congenital anomalies.In this report we attempt to question whether the association between MRKHS and situs inversus is a rare feature of the müllerian dysgenetic spectrum or whether it is the result of random association.     

Laparoscopic total gastrectomy for advanced gastric cancer in a patient with situs inversus totalis

Situs inversus totalis (SIT) is a rare congenital anomaly. Generally, laparoscopic surgery is difficult to perform in patients with SIT because of both the potential challenges associated with unexpected vascular anomalies and the lack of standardized strategy for handling such cases. This is the first report of laparoscopic total gastrectomy with lymph node dissection for advanced gastric cancer in a patient with SIT. A 79‐year‐old man with SIT was diagnosed with advanced gastric cancer. We performed laparoscopic total gastrectomy with modified D2 lymph node dissection (D2 without splenectomy) and esophagojejunal anastomosis using an overlap method involving retrocolic Roux‐en‐Y reconstruction. The total operating time was 232 min, and blood loss was 110 mL. There were no postoperative complications. In summary, laparoscopic total gastrectomy for gastric cancer can be performed safely, even in a patient with SIT.     

Successful Catheter Ablation for Multiple Atrial Arrhythmias in a Patient with Situs Inversus Totalis

A 70-year-old woman with situs inversus totalis underwent catheter ablation for atrial fibrillation and atrial flutter. Although her morphologic left atrium (LA) was enlarged, we performed cryoballoon ablation and liner radiofrequency ablation of the cava-tricuspid isthmus without mapping atrial arrhythmias. However, a different form of atrial tachycardia (AT) recurred. We performed catheter ablation a second time using a three-dimensional electroanatomic mapping system. AT was not terminated by the liner ablation at the roof of morphologic LA and mitral isthmus but sustained by changing the atrial activation sequence and cycle length. Multipolar mapping catheter revealed that fractionated low-amplitude potentials were densely located in a limited area of the anterior morphologic LA, and an activation map demonstrated the presence of small-circuit reentry with an extremely slow conduction at the anterior morphologic LA. A single energy application targeting the fragmented potentials successfully terminated the AT. We successfully treated multiple ATs with a complex anatomy using a three-dimensional electroanatomic mapping system.     

Laparoscopic cholecystectomy for cholecystolithiasis in a case with situs inversus totalis

We report a case of cholecystolithiasis associated with situs inversus totalis (SIT) that had been successfully treated with a laparoscopic cholecystectomy. Although cholecystolithiasis associated with SIT is rare, trained surgeons who perform unusual surgical procedures, even if they have not experienced such a case, would perform laparoscopic cholecystectomy for cholecystolithiasis associated with SIT easily and safely.
