Abdominal ultrasonography and CT scan confirmed the diagnosis of a gallstone, as well as, situs inversus; the liver and gallbladder on the left side and the spleen on the right. The biliary system was thought to be left-right reversal, mirror image in the view of drip infusion cholangiogram and MRI. Laparoscopic cholecy stectomy was safely performed, despite of unexpected aberrant cystic artery running inferior to cystic duct of situs inversus. Laparoscopic surgeon should be careful for view of reversed relationships and also existence of other anomalies.展开更多

Recently, several laparoscopic operations have been reported in patients with situs inversus. We describe laparoscopic hemicolectomy with radical lymphadenectomy in such a patient. Careful consideration of the mirror-image anatomy permitted safe operation using techniques not otherwise differing from those in ordinary cases. Thus, curative laparoscopic surgery for colon cancer in the presence of situs inversus is feasible and safe.展开更多

We report the first patient with PC and SIT who underwent robot-assisted pancreaticoduodenectomy. A 57-year-old male patient presented to our hospital with epigastric pain, nausea, and weight loss over 1 month. Preoperative diagnostic modalities revealed a resectable pancreatic ductal adenocarcinoma at the head and neck junction of the pancreas. The patient also had a rare condition called SIT. Then, the patient underwent Da Vinci robot-assisted pancreaticoduodenectomy (RPD) in our center. After the operation, the patient recovered well without complications. Until now, the patient was followed up 5 months, and the quality of life was well without tumor recurrence or metastasis. To the authors’ knowledge, this is the first RPD for PC in SIT patients.展开更多

It is a rare congenital malformation often discovered in childhood. In adults, it can lead to misdiagnosis. Clinical case: A 35-year-old female patient, seen in a hepatogastroenterology consultation for acute spontaneous pain in the right hypochondrium. She had no particular clinical history. A diagnosis of hepatopathy was suspected. Abdominal and pelvic CT scans showed the left liver, stomach and spleen in the right hypochondrium, but with the heart in place, suggesting incomplete situs inversus. The evolution in our patient was spontaneously resolved with analgesics and antispasmodics, which leads us to believe that the volvulus was probably partial and without other complications. Conclusion: In developing countries, antenatal diagnosis of situs inversus is rare and is usually made during a pathology that leads the patient to a medical consultation. CT is one of the key paraclinical examinations for its diagnosis as genetic tests are not widely available.展开更多

The estimated incidence of SI is 1/15 000 to 1/10 000 live births. The disease is often complicated with biliary atresia, polysplenia, intestinal nonrotation, preduodenal portal vein, aberrant hepatic artery, or absence of the suprarenal inferior vena cava. In 2004, we performed a liver transplantation on a patient with SI complicated with hepatolithiasis, end-stage liver cirrhosis and liver failure, because of the unavailability of donor organs, the operation became more complicated and difficult.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

It is generally classified into three: situs inversus totalis, situs abdominis (with levocardia), and situs ambiguous. Although many patients with situs inversus do go on to live normal uneventful lives, several cardiovascular, gastrointestinal as well multisystemic comorbidities have been shown to be associated with the condition. The aim of the study is to analyse and give an overview of the proportion of the different types of situs inversus and the common major comorbidities at presentation (both acquired and congenital) including the age and sex predilection, as well as the proportion of the different diagnostic methods for situs inversus. Method: Published cases from English medical journals were evaluated and analysed. Results: 191 published cases on situs inversus were reviewed. Situs inversus totalis had the highest proportion (82.7%) compared to situs ambiguous (13.6%) and situs inversus abdominis (with levocardia) (3.7%). There was no sex predilection, with a male to female ratio of 0.96 (P = 0.83). According to our study, the commonest comorbidity patients with situs inversus presented with were cholelithiasis (13.6%) and Kartagener syndrome (9.4%). Presenting comorbidities with digestive system affectation had the highest proportion (57.1%). Conclusion: The study established a significant association between acquired digestive system comorbidities like cholelithiasis, compared to other comorbidities.展开更多

We present a case of presumed lung cancer in a 58 years old lady with SIT successfully treated by VATS lobectomy via an anterior approach. She presented with an incidental solitary pulmonary nodule in her right lower lobe, which had moderate FDG uptake on the PET scan. The nodule was too deep to permit safe wedge biopsy, due to proximity of a large pulmonary arterial branch. 3D-CT images were invaluable in pre-operative assessment of the anatomy and were the key to safe completion of right VATS lower lobectomy. Sectioning the lung after retrieval of the specimen suggested a chondroid hamartoma;therefore, systemic nodal dissection (SND) was not contemplated. The final histology confirmed the diagnosis of chondroid hamartoma. In an unusual anatomy such as SIT, 3D-CT allows construction of virtual reality models that can be viewed and manipulated before and during the operation to understand the anatomy better, highlight caveats around target structures and enable localisation of lesions unlikely to be palpated intra-operatively.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 that is characterized by a complete mirror image of the typical arrangement of the thoracic and abdominal viscera.Performing thoracoscopic segmentectomy for a patient with lung cancer and SIT is an extremely skilled and challenging surgical procedure.CASE SUMMARY A 41-year old woman with a medical history of dextrocardia since childhood was admitted to our hospital with a mixed ground-glass opacity(mGGO)in her left lung field,discovered by computed tomography during her health checkup.In order to facilitate surgical orientation,three-dimensional computed tomography bronchography and angiography(3D-CTBA)was preoperatively carried out.The result of 3D-CTBA was consistent with the diagnosis of SIT and an mGGO in the posterior segment of the left upper lobe(LS2).Surgery was conducted in accordance with preoperative 3D-CTBA and designed surgical procedure,combined with intraoperative navigation.Final pathological examination revealed in situ adenocarcinoma.The patient’s postoperative condition was uneventful and no complications were observed.CONCLUSION We present the first case of lung cancer in a patient with SIT who successfully underwent thoracoscopic segmentectomy assisted by 3D-CTBA.This is a new technique that covers precise confirmation and dissection of targeted structures and intersegmental demarcation,and can help achieve a meticulous anatomical segmentectomy.
文摘BACKGROUND Situs inversus totalis(SIT)may be an incidental finding in asymptomatic children.Patients may not understand the implications of this condition and the importance of relaying the diagnosis to their healthcare providers.CASE SUMMARY We report an asymptomatic seventeen-year-old adolescent with previouslydiagnosed SIT who presented for a routine well-child visit.During history taking,he denied any past medical conditions,including cardiovascular conditions.Only when physical exam revealed point of maximal impulse and heart sounds on the right side,did he convey that he had been diagnosed with SIT incidentally at age of 12 years.He was not aware of associated conditions or the potential implications of his diagnosis,nor did he realize it is pertinent medical history to be relayed to healthcare providers.Chest X-ray confirmed dextrocardia and abdominal X-ray showed right-sided stomach.Abdomen sonogram showed left-sided liver and right-sided spleen.Echocardiogram showed normal valvular structure and function.A comprehensive discussion was provided to address the patient’s lack of understanding that SIT is a medical diagnosis with potential implications.CONCLUSION While SIT is rare and mostly asymptomatic,affected patients may not comprehend the importance of the diagnosis and its potential ramifications.Recognition of the patient’s lack of awareness allows the healthcare provider to educate the patient and hopefully can prevent potential medical and surgical complications.
文摘Situs inversus is a rare congenital anomaly referring to the mirror image of the abdominal and thoracic viscera. It can be discovered routinely or on the occasion of a complication related or not to situs inversus. We report a case of Situs inversus discovered incidentally during surgery for acute intestinal obstruction caused by an iatrogenic uterine perforation.
文摘Situs inversus is an abnormal placement of the thoracic and/or abdominal organs that are inverted right/left from normal. It is a rare congenital malformation often discovered in childhood. In adults, it can lead to misdiagnosis. Clinical case: A 35-year-old female patient, seen in a hepatogastroenterology consultation for acute spontaneous pain in the right hypochondrium. She had no particular clinical history. A diagnosis of hepatopathy was suspected. Abdominal and pelvic CT scans showed the left liver, stomach and spleen in the right hypochondrium, but with the heart in place, suggesting incomplete situs inversus. The evolution in our patient was spontaneously resolved with analgesics and antispasmodics, which leads us to believe that the volvulus was probably partial and without other complications. Conclusion: In developing countries, antenatal diagnosis of situs inversus is rare and is usually made during a pathology that leads the patient to a medical consultation. CT is one of the key paraclinical examinations for its diagnosis as genetic tests are not widely available.
文摘Situs inversus （SI） is a congenital anomaly characterized by the mirror-image orientation of the inner organs. The estimated incidence of SI is 1/15 000 to 1/10 000 live births. The disease is often complicated with biliary atresia, polysplenia, intestinal nonrotation, preduodenal portal vein, aberrant hepatic artery, or absence of the suprarenal inferior vena cava. In 2004, we performed a liver transplantation on a patient with SI complicated with hepatolithiasis, end-stage liver cirrhosis and liver failure, because of the unavailability of donor organs, the operation became more complicated and difficult.
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Background: Situs inversus is a rare congenital disorder that causes a reversal in the anatomical arrangement of chest and abdominal organs, such that the organs are mirror images of the normal anatomy. It is generally classified into three: situs inversus totalis, situs abdominis (with levocardia), and situs ambiguous. Although many patients with situs inversus do go on to live normal uneventful lives, several cardiovascular, gastrointestinal as well multisystemic comorbidities have been shown to be associated with the condition. The aim of the study is to analyse and give an overview of the proportion of the different types of situs inversus and the common major comorbidities at presentation (both acquired and congenital) including the age and sex predilection, as well as the proportion of the different diagnostic methods for situs inversus. Method: Published cases from English medical journals were evaluated and analysed. Results: 191 published cases on situs inversus were reviewed. Situs inversus totalis had the highest proportion (82.7%) compared to situs ambiguous (13.6%) and situs inversus abdominis (with levocardia) (3.7%). There was no sex predilection, with a male to female ratio of 0.96 (P = 0.83). According to our study, the commonest comorbidity patients with situs inversus presented with were cholelithiasis (13.6%) and Kartagener syndrome (9.4%). Presenting comorbidities with digestive system affectation had the highest proportion (57.1%). Conclusion: The study established a significant association between acquired digestive system comorbidities like cholelithiasis, compared to other comorbidities.
文摘The aim of this case report is to raise awareness about the use of 3-Dimentional Computed Tomography (3D-CT) virtual reality imaging as a routine pre-operative tool for evaluation of unusual anatomy such as Situs Inversus Totalis (SIT). We present a case of presumed lung cancer in a 58 years old lady with SIT successfully treated by VATS lobectomy via an anterior approach. She presented with an incidental solitary pulmonary nodule in her right lower lobe, which had moderate FDG uptake on the PET scan. The nodule was too deep to permit safe wedge biopsy, due to proximity of a large pulmonary arterial branch. 3D-CT images were invaluable in pre-operative assessment of the anatomy and were the key to safe completion of right VATS lower lobectomy. Sectioning the lung after retrieval of the specimen suggested a chondroid hamartoma;therefore, systemic nodal dissection (SND) was not contemplated. The final histology confirmed the diagnosis of chondroid hamartoma. In an unusual anatomy such as SIT, 3D-CT allows construction of virtual reality models that can be viewed and manipulated before and during the operation to understand the anatomy better, highlight caveats around target structures and enable localisation of lesions unlikely to be palpated intra-operatively.
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.
