What about performing this procedure on a patient with situs inversus totalis and what are the difficulties of this operation for a right-handed surgeon? We presented a 35-year-old man with unknown situs inversus totalis who was admitted with epigastric pain and digestive problems. Ultrasonography and computed tomography of the abdomen confirmed the diagnosis of a gallstone. Besides, the liver and gallbladder were on the left side and the spleen was on the right. All systems were left-right reversal as mirror image in all diagnostic studies. Laparoscopic cholecystectomy was safely performed, despite of difficulties of situs inversus. The patient was discharged on postoperative day 1. It should be considered that existence of other anomalies may easily cause uninvited injuries. In the patients with situs inversus, laparoscopic cholecystectomy can be safely managed by an experienced surgeon through laparoscopy, and also hepatobiliary surgery.展开更多

Occasionally,patients with this condition are diagnosed with malignant tumors. We report a case of a 60-yearold woman with gastric cancer and SIT. Laparoscopyassisted distal gastrectomy(LADG) with D2 lymph node dissection and Billroth Ⅱ anastomosis were performed successfully on the patient by careful consideration of the mirror-image anatomy. The operation required 230 min, and no intraoperative complications occurred. The final pathological report was p T4 a N0M0,according to the American Joint Committee on Cancer 7th edition staging guidelines. The postoperative course was favorable, and the patient was discharged on postoperative day 8. We believe that this is the first case of LADG with D2 lymphadenectomy reported in a SIT patient with advanced gastric cancer.展开更多

Situs Inversus Totalis (SIT) is a congenital anomaly characterized by complete transposition of abdominal and thoracic organs. Patients with this anomaly usually lead a normal life. We report a fourteen-year old Nigerian who was found to have dextrocardia with situs inversus totalis while presenting for treatment for a different problem. Conclusion: Situs inversus totalis is a rare finding. This report underscores the need for routine screening of children so that such congenital anomalies can be identified and complications that follow it averted timely.展开更多

文摘BACKGROUND Situs inversus totalis(SIT)is a rare condition in which the positions of abdominal and thoracic organs present a“mirror image”of the normal ones in the median sagittal plane.Although minimally invasive surgery has evolved to achieve laparoscopic gastrectomy for gastric cancer(GC)patients with SIT,it is difficult to perform lymphadenectomy(LND)in such a transposed anatomical condition.Herein,we report the cases of two patients with SIT who successfully underwent laparoscopy-assisted gastrectomy(LAG)with D2 LND.CASE SUMMARY Case 1:A 65-year-old man was admitted for intermittent abdominal pain and distension,occasional belching,and acid reflux for 4 mo.He was diagnosed with GC(cT3N1-2M0)with SIT.Before surgery,he had undergone four cycles of neoadjuvant chemotherapy and immunotherapy.Then,the patient was evaluated as having a partial response,and laparoscopy-assisted distal gastrectomy with D2 LND and Billroth II reconstruction were performed.The operation was performed successfully within 240 min with an estimated blood loss of 50 mL and no severe complications.The patient was discharged on postoperative day(POD)9.Case 2:A 55-year-old man was admitted for upper abdominal distension with pain and discomfort after eating for 3 mo.He was diagnosed with GC(cT3N1M0)with SIT.He had a history of hypertension for more than 10 years;however,his blood pressure was well-controlled via regular medication.We performed laparoscopy-assisted total gastrectomy with D2 LND and Roux-en-Y reconstruction.The operation was performed successfully within 168 min with an estimated blood loss of 50 mL and no severe complications.The patient was discharged on POD 10.CONCLUSION LAG with D2 LND could be considered an accessible,safe,and curative procedure for advanced GC patients with SIT.
文摘BACKGROUND Situs inversus totalis(SIT)is a rare congenital condition in which the structure of the abdominal and thoracic cavities is the mirror image of normal.This anatomic reversal makes laparoscopic surgery difficult when treating colorectal cancer.CASE SUMMARY We describe the successful laparoscopic hemicolectomy of a 68-year-old Chinese woman with SIT and ascending colon cancer.Based on preoperative imaging and careful consideration of the patient’s anatomy,the position of the surgeon was modified such that the surgeon stood between her legs,while the surgical assistant and endoscopist stood to the surgeon’s left.Trocar position was also adjusted appropriately.The surgery lasted 178 min,during which the patient lost 50 mL of blood.Pathology analysis of the resected tumor confirmed an adenocarcinoma in clinical stage pT3N0M0,without lymph node involvement.The patient experienced no postoperative complications and was discharged 10 d after surgery.CONCLUSION This case illustrates that careful positioning of the surgeon can facilitate laparoscopic surgery of SIT patients.
文摘SITUS inversus totalis （SIT） is a complete mirrorimage of the thoracic and abdominal viscera,occurring at an incidence of 1 in 5000-20 000live births.1, 2 It is supposed to originate from anabnormal rotation of the cardiac tube during embryogenesis.Although SIT is a congenital anomaly, most of patients aredetected accidentally at the time of radiological investigation.Hepatocellular carcinoma （HCC） is usually associated withliver cirrhosis and portal hypertension in Chinese. Presenceof hypersplenic thrombocytopenia is a common consequenceof long-term portal hypertension in cirrhoticpatients.
文摘Situs inversus totalis(SIT) is a rare anomaly in which the abdominal and thoracic cavity structures are located opposite to their usual positions. Occasionally,patients with this condition are diagnosed with malignant tumors. We report a case of a 60-yearold woman with gastric cancer and SIT. Laparoscopyassisted distal gastrectomy(LADG) with D2 lymph node dissection and Billroth Ⅱ anastomosis were performed successfully on the patient by careful consideration of the mirror-image anatomy. The operation required 230 min, and no intraoperative complications occurred. The final pathological report was p T4 a N0M0,according to the American Joint Committee on Cancer 7th edition staging guidelines. The postoperative course was favorable, and the patient was discharged on postoperative day 8. We believe that this is the first case of LADG with D2 lymphadenectomy reported in a SIT patient with advanced gastric cancer.
文摘Situs inversus totalis(SIT) is a rare anomaly in which the abdominal and thoracic cavity structures are opposite their usual positions.Occasionally,a few patients with a combination of this condition and malignant tumors have been encountered.Recently,several laparoscopic operations have been reported in patients with SIT.We report a case of an 83-year-old man with situs inversus totalis who developed colon cancer after open distal gastrectomy.Laparoscopic hemicolectomy with radical lymphadenectomy in such a patient was successfully performed by careful consideration of the mirror-image anatomy.Techniques themselves was not different from those in ordinary cases.Thus,curative laparoscopic surgery for colon cancer in the presence of situs inversus totalis is feasible and safe.

文摘BACKGROUND Situs inversus totalis(SIT)is a rare group of congenital developmental malformations in the clinical setting,with all organs in the chest and abdomen existing in a mirror image reversal of their normal positions.Few reports have described laparoscopic surgery for colorectal cancer in patients with SIT,and it is considered difficult even for an experienced surgeon because of the mirror positioning.We present a case report of laparoscopic radical resection of a colonic splenic flexure carcinoma in a patient with SIT.CASE SUMMARY A 72-year-old male was referred to our hospital with colonic splenic flexure carcinoma,and computed tomography showed that all the organs in the chest and abdomen were inverted.Laparoscopic hemicolectomy with complete mesocolic excision was safely performed.The operating surgeon stood on the patient’s left side,which is opposite of the normal location.CONCLUSION Abdominal computed tomography is an effective method for diagnosing SIT preoperatively in patients with colonic splenic flexure carcinomas.Laparoscopic radical resection is difficult,but it is well established and safe.The surgeon should stand in the opposite position and perform backhand operations.
文摘Hepatocellular carcinoma(HCC)is the most commonly diagnosed carcinoma and one of the leading causes of cancer-related deaths worldwide.Situs inversus totalis(SIT)is a congenital condition where in the internal organs of the abdomen and thorax lie in mirror images of their normal position.Thus far,there are very few reports on cases of SIT coexisting with HCC.Our case series is probably the largest series in world literature.The cohort of this retrospective study included a total of nine patients diagnosed with SIT-HCC and treated in our hospital between January 2013 and May 2018.Clinical characteristics,prognostic factors,and outcomes were summarized.Treatment strategies included surgery,transarterial chemoembolization,and microwave ablation.The diagnosis and treatment of patients with SIT are challenging because of organ reversion.The current treatment strategies for different stages of liver cancer are safe and feasible for patients with SIT-HCC.
文摘BACKGROUND Alopecia areata(AA)is an inflammatory disease with autoimmune,environmental,and inherited components directed at the hair follicle,either limited to patchy hair loss over the scalp(Focalis,AF),total loss of scalp hair(Totalis,AT),or total loss of both scalp and body hair(Universalis,AU).Despite multiple treatment modalities,no therapy exists.Vitamin D deficiency in patients with AA/AT/AF influences disease severity and duration,inversely correlating with inflammation histologically.CASE SUMMARY Three girls presented with AT(P1),AU(P2),and AF(P3)at the ages of 1,5,and 5 years,respectively.For P1-P2,all available treatments implemented for 2 years had failed.We started an initial 6-mo repletion with oral cholecalciferol 2000/4000 IU/d,with no apparent effect.Then we attempted immunomodulation using oral calcitriol and its analog paricalcitol.On calcitriol,0.5 mcg/d P1 regrew hair within 6 mo.After 4 years,a relapse with loss of eyebrow hair was resolved after doubling the calcitriol dose to 0.5 mcg×2/d;the results have been maintained for 6 years to date.On calcitriol,0.25 mcg×3/d P2 led to the development of asymptomatic hypercalcemia-hypercalciuria,which was immediately resolved by switching to paricalcitol 2 mcg×3/d;mild tolerable hypercalciuria was maintained.Hair regrowth was observed at 6 mo,stabilizing only as fur at 12 mo.AF in P3 was resolved completely within 3 mo on a daily high dose(8000 IU)of cholecalciferol.CONCLUSION Vitamin D may have immunomodulating therapeutic impact on AT/AU/AF,which needs to be explored with further pilot clinical trials.

文摘BACKGROUND Single atrium with single ventricle,or a two-chambered heart,is an extremely rare congenital malformation.Few cases with two-chambered heart surviving to adulthood have been reported.CASE SUMMARY We reported an adult female patient with a two-chambered heart and situs inversus totalis accompanied by multiple pregnancies and abortions.Magnetic resonance imaging detected a two-chambered heart.B-ultrasound-guided uterine aspiration was performed to absorb 8 g and 10 g of organized villus and decidual tissues,respectively,with a small amount of bleeding.Postoperatively,cyanosis and fatigue-induced shortness of breath were gradually relieved.The patient has currently outlived all similar cases reported so far.CONCLUSION Hemodynamic changes in pregnant women with two-chambered heart impaired cardiac function,responsible for hypoperfusion and miscarriage.
文摘This recipient with situs inversus totalis(SIT) was a 60-year-old female who had hepatitis B-related endstage liver disease.Preoperative donor evaluation showed that the right posterior section satisfied graft volume and was space-fitting in the recipient hepatic fossa when it was rotated 180 degrees.The operation and postoperative course progressed satisfactorily.Three weeks after living donor liver transplantation(LDLT),the graft function was disturbed by compression of bottom-placed right hepatic vein.This was treated with a vascular stent and subsequently the graft function was normalized.The present case shows that LDLT for patients with SIT using a right posterior section graft is feasible.
文摘SITUSinversus totalis is uncommon anatomic anomaly, with gallbladder on the left side} Since the first known laparoscopic cholecystectomy in a patient with situs inversus has been reported by Camposand Sipes in 1991,2 there have been only approximately 40 cases of laparoscopic cholecystectomy performed in patients with situs inversus reported in the published literatures.3＇ 4 These cases may cause difficulties in the diagnostic and therapeutic management due to the mirror-image anatomy during operation, which requires more technically procedures and needs reorientation of visuomotor skills to the left upper quadrant. We herein discuss technical and diagnostic difficulties and review the literatures.

文摘Background: Total situs inversus, (also called situs transversus or oppositus) known as mirror image dextrocardia, is characterized by a heart on the right side of the midline while the liver is on the left side. Situs Inversus Totalis (SIT) is a congenital anomaly characterized by complete transposition of abdominal and thoracic organs. Patients with this anomaly usually lead a normal life. We report a fourteen-year old Nigerian who was found to have dextrocardia with situs inversus totalis while presenting for treatment for a different problem. Conclusion: Situs inversus totalis is a rare finding. This report underscores the need for routine screening of children so that such congenital anomalies can be identified and complications that follow it averted timely.
