Background: Situs inversus totalis is a rare congenital anomaly defined by a mirror-image of thoracic and abdominal viscera. Discrete cases of situs inversus totalis and its association with gastrointestinal tumors have been reported. Here we report the first case of pancreatic-head serous cystadenoma in patient with situs inversus totalis.
Case Presentation: A 68-year-old woman presented with an abdominal mass that appeared four months ago. She was otherwise asymptomatic and her physical examination was unremarkable. Chest X-ray revealed dextrocardia. CT scan confirmed situs inversus totalis with an irregular, clear border, heterogenous pancreatic-head mass measuring 11 cm. Laboratory studies were within the reference range and pancreatic tumor markers were normal. We performed an elective open pancreaticoduodenectomy followed by an end-to-side pancreaticojejunostomy, an end-to-side choledochojenunostomy, and a side-to-side gastrojejunostomy. The immediate postoperative course was uneventful, and she was discharged four days later without any complications. Four-month of follow-ups revealed no recurrent or relapsed disease.
Discussion: Although the steps of the Whipple procedure are almost the same in SIT patients. The main differences during the operation in SIT patients are the anatomical variations and how the surgeon will cope with them to avoid any mistakes.
Conclusion: The surgeons should improve their skills and gain control in both hands to easily adjust with the anatomic variations of situs inversus totalis and reduce the operation time and the associated risk of long operation time.

Inositol polyphosphate-5-phosphatase E (INPP5E) is a 5-phosphatase critically involved in diverse physiological processes, including embryonic development, neurological function, immune regulation, hemopoietic cell dynamics, and macrophage proliferation, differentiation, and phagocytosis. Mutations in cause Joubert and Meckel-Gruber syndromes in humans; these are characterized by brain malformations, microphthalmia, situs inversus, skeletal abnormalities, and polydactyly. Recent studies have demonstrated the key role of INPP5E in governing intracellular processes like endocytosis, exocytosis, vesicular trafficking, and membrane dynamics.

The biliary system exhibits significant anatomical variations, which pose challenges for most surgeons during cholecystectomy. Among these variations, a true left-sided gallbladder (LSG) is an uncommon finding. In such cases, the gallbladder is located to the left of the round ligament.

Situs anomalies, including situs inversus and situs ambiguous (SAMB), are rare congenital conditions typically noted in pediatric populations, with SAMB being particularly uncommon in adults. This case study addresses the incidental discovery of situs ambiguous with polysplenia in a 65-year-old man evaluated for suspected adrenal adenoma. The patient's medical history included benign prostatic hyperplasia and tuberculous pleurisy.

Background: Primary ciliary dyskinesia (PCD) is a rare autosomal recessive disorder characterized by dysfunction of motile cilia. While approximately 50 genes have been identified, around 25% of PCD patients remain genetically unexplained; elucidating the pathogenicity of specific variants remains a challenge.
Methods: Whole exome sequencing (WES) and Sanger sequencing were conducted to identify potential pathogenic variants of PCD.

Introduction And Importance: Situs inversus is an anatomical rare condition in which visceral organs are not located in its normal position, with a reversal anatomical orientation.
Case Presentation: We present a case of an 27-year-old male with a Body Mass Index (BMI) of 36.02 Kg/m2, who was programed for a Endoscopic Sleeve Gastroplasty (ESG), in which Situs inversus was documented.
