Lung cancer mimicking aortic dissecting aneurysm in a patient with situs inversus totalis.

ABSTRACT: Lung cancer and situs inversus totalis are two completely irrelevant conditions. The likelihood of both conditions occurring simultaneously in one person is very rare. We report here a case of a 50-year-old man who presented with intermittent chest pain. Enhanced computed tomography of the chest showed situs inversus totalis and a round mediastinal mass embracing the thoracic aorta. The primary diagnosis was suggested as pseudo aortic dissecting aneurysm. However, a tumor in the right lower lung was discovered during surgery, which enclosed and invaded the thoracic aorta. Finally, the patient successfully underwent right lower lobectomy accompanied by lymph node excision and partial replacement of the thoracic aorta with an artificial vascular graft under cardio-pulmonary bypass.

Biliary stone in patient with situs inversus totalis.

Project description:Introduction and significanceSitus inversus totalis is characterized by the complete transposition of thoracic and abdominal viscera. Individuals can live asymptomatically with this condition; however, it may be associated with certain abnormalities of the organs involved.Case presentationHerein, we present a case of a situs inversus totalis woman presented with choledocholithiasis. Elective laparoscopic cholecystectomy was performed on the patient with intraoperative modifications. The patient was discharged in a healthy condition.Clinical discussionSeveral case reports have documented the typical presentation of cholelithiasis, which is characterized by pain in the left upper quadrant and epigastric region. Our patient exhibited similar symptoms and was diagnosed with choledocholithiasis.ConclusionsDiagnostic and therapeutic management of morbidities in SIT individuals can be performed with recommended modifications that can lead to favorable outcomes.

Laparoscopic biliopancreatic diversion for a morbidly obese patient with situs inversus totalis: Case report.

Project description:INTRODUCTION:Situs inversus is a rare congenital anomlay in which the thoracic and abdominal organs are sited on the opposite side to that of normal anatomy. Its etiology is still unknown. It is classified into situs inversus partialis and situs inversus totalis. It is discovered incidentally in most cases. Any surgical intervention for such patients may encounter intra-operative technical difficulties due to anatomical differences, particularly if a laparoscopic approach is adopted, as in bariatric surgeries where the obesity itself opposes an added surgical challenge. CASE PRESENTATION:A female patient with a BMI of 52.1?Kg/m2 was being prepared for biliopancreatic diversion. She was diagnosed incidentally as having situs inversus totalis during the preoperative evaluation. She underwent an uneventful laparoscopic biliopancreatic diversion. She was followed up regularly in the bariatric surgery clinic for 9 years. Her last BMI was 29?Kg /m2 with no signs or symptoms of metabolic complications. CONCLUSION:This case report demonstrates that biliopancreatic diversion can be done safely in morbidly obese patients with situs inversus by an experienced bariatric surgeon in a specialized well-equipped center.

Just flip it!-CRT implantation in a patient with dextrocardia and situs inversus totalis.

Project description:Implantation of a cardiac resynchronization therapy (CRT) device in patients with congenital heart disease may be challenging because of the particular underlying anatomy. We present the case of a right-sided transvenous implantation of a dual-chamber CRT-D device in a patient with situs inversus totalis and mirror image dextrocardia. To facilitate our anatomic orientation and to overcome unusual hand-eye coordination problems, we decided to flip the fluoroscopic image projection by 180° (right-left), creating the optical impression of a "normalized" heart position (levocardia). This simple approach allowed us to successfully implant the device using a conventional left-sided CRT delivery system.

Left-sided perforated appendicitis in a patient with situs inversus totalis, a case report.

Project description:Situs inversus, an uncommon disorder, causes the orientation of asymmetric organs to be opposite to that of normal anatomy. It can be either partial, affecting only the thoracic or abdominal cavities, or full, involving the transposition of both the thoracic and abdominal organs. A 31-year-old Ethiopian male patient presented with migratory abdominal pain in the left lower quadrant for 3 days. Associated with the pain, he experienced symptoms of nausea, vomiting of ingested matter, and loss of appetite. Investigations were consistent with left-sided appendicitis with situs inversus totalis. Therefore, the patient was operated on and discharged with no perioperative complications. Appendicitis is a rare cause of left lower quadrant pain. In order to reduce the delay in patient treatment and avoidable perioperative complications, emergency physicians, radiologists, and surgeons must become more knowledgeable about situs inversus and left side appendicitis.

A Homozygous Nme7 Mutation Is Associated with Situs Inversus Totalis.

Project description:We investigated the cause of situs inversus totalis (SIT) in two siblings from a consanguineous family. Genotyping and whole-exome analysis revealed a homozygous change in NME7, resulting in deletion of an exon causing an in-frame deletion of 34 amino acids located in the second NDK domain of the protein and segregated with the defective lateralization in the family. NME7 is an important developmental gene, and NME7 protein is a component of the ?-tubulin ring complex. This mutation is predicted to affect the interaction of NME7 protein with this complex as it deletes the amino acids crucial for the binding. SIT associated with homozygous deletion in our patients is in line with Nme7(-/-) mutant mice phenotypes consisting of congenital hydrocephalus and SIT, indicating a novel human laterality patterning role for NME7. Further cases are required to elaborate the full human phenotype associated with NME7 mutations.

Mens inversus in corpore inverso? Language lateralization in a boy with situs inversus totalis.

Project description:Situs inversus totalis is a rare condition where the visceral organs are organized as a mirror image of default organ position. In this study we picture the co-development between brain and visceral organs in a case of situs inversus totalis from a fetal stage to adolescence and compare our findings to an age-, gender-, and education-matched control with normal position of thoracic and abdominal organs. We show that in this case of situs inversus, functional and structural brain lateralization do not coincide with visceral organ situs. Furthermore, cognitive development in situs inversus is normal. To our knowledge, this is the first report of antenatal cerebral origins of structural and functional brain asymmetry in a case of situs inversus totalis.

Comprehensive Molecular Profiling of Colorectal Cancer With Situs Inversus Totalis by Next-Generation Sequencing.

Project description:BackgroundColorectal cancer (CRC) is one of the most prevalent malignances worldwide. However, CRC with situs inversus totalis (SCRC) is extremely rare, and molecular characterization of this disease has never been investigated.MethodsTumor tissue samples from 8 patients with SCRC and 33 CRC patients without situs inversus totalis (NSCRC) were subjected to multigene next-generation sequencing.ResultsThe most frequently mutated genes in SCRC were APC, TP53, CHEK2, MDC1, GNAQ, KRAS, and SMAD4. A high frequency of SCRC tumors had mutations in DNA damage repair genes. Single amino acid substitutions in the DNA damage repair genes caused by continuous double base substitution was identified in the majority of this population. Furthermore, mutational profiles showed notable differences between the SCRC and NSCRC groups. In particular, CHEK2, MDC1, GNAQ, SMAD4, BRCA1, HLA-B, LATS2, and NLRC5 mutations were more frequently observed in SCRC patients. The mutation loci distributions of KRAS in the SCRC cohort differed from that of the NSCRC cohort. Additionally, differences in the targeted genomic profiles and base substitution patterns were observed between the two groups.ConclusionsThese findings comprehensively revealed a molecular characterization of SCRC, which will contribute to the development of personalized therapy and improved clinical management of SCRC patients.

Laparoscopic cholecystectomy for left-sided gall bladder in situs inversus totalis patient, a technically demanding procedure.

Project description:Situs inversus is a condition in which the anatomical viscera are placed in a reverse anatomical location, it may be partial affecting the thoracic organs or the abdominal organs, or total affecting both. A 28-year-old man who was a known case of situs inversus totalis presented with epigastric pain and left hypochondrial pain. ultrasound revealed multiple gall stones in a left-sided gall bladder, laparoscopic cholecystectomy was done successfully for him with no complications. Patient position during surgery and the sites of the laparoscopic ports greatly affect the performance during surgery. Identification of the anatomical structures which are arranged in a mirror image pattern is the key for successful surgery. The critical view of safety should be identified before any structure is clipped or divided. A right-handed surgeon will feel more impairment during surgery for a left-sided gall bladder, while a left-handed surgeon will do it with better comfort. Surgeries for such cases are better to be performed by a surgeon with massive experience in laparoscopy or by a hepatobiliary surgeon, it may not be suitable for surgeons in training. MRCP will show the biliary anatomy prior to surgery and CT-scan with dual phase contrast will help to show any associated vascular abnormalities.

Laparoscopic sleeve gastrectomy in a patient with Situs Inversus Totalis: A case report and literature review.

Project description:Introduction& Importance: Laparoscopic sleeve gastrectomy (LSG) is a widely accepted and effective bariatric surgery for achieving weight loss in patients with extreme obesity. Performing this surgical procedure in patients with congenital anatomical changes including situs inversus (SI) is a challenge for the surgical team. In this condition, the orientation of intra-abdominal organs is the mirror image of those in normal populations.Case presentationHerein, we present a 29-year-old female with situs inversus totalis who successfully underwent an LSG surgery with proper weight loss post-operatively and no early and late complications.Clinical discussionBy reviewing the literature for patients with SI undergoing the same procedure, all patients achieved significant weight loss. Three out of nineteen cases experienced complications which were controlled without significant morbidity or mortality.Conclusion: we concluded that LSG will be a safe and effective surgery for the treatment of extreme obesity in SI patients, if the condition is diagnosed preoperatively.
