Acute Cholecystitis in a Patient With Situs Inversus Totalis: An Unexpected Finding

Acute Cholecystitis in a Patient With Situs Inversus

A rare disorder called situs inversus partialis (SIP) is characterized by the transposition of organs in the abdomen or thoracic cavity from one side of the body to the other (the mirror image of normal). Autosomal dominant, autosomal recessive, rare genetic mutations, and X-linked recessive inheritance patterns have been identified to be involved in this condition. Laparoscopic cholecystectomies have been successfully performed on patients with SIT. Due to challenges in spatial orientation and the identification of anatomical variations brought on by the abdominal organs' mirror image, surgery is more complicated and takes longer. We describe a 40-year-old female case who had acute cholecystitis. Laparoscopic cholecystectomy was used to treat this patient, a highly effective procedure for both the treatment and care of these patients. Post-surgical examination and follow-up revealed improvement in the patient's condition without subsequent complications.

A Case of Left-Sided Acute Appendicitis in a 45-Year-Old Man with Situs Inversus Totalis Managed by Emergent Laparoscopic Appendectomy

BACKGROUND Situs inversus totalis (SIT) is a rare congenital abnormality that includes mirror-image transposition of both the abdominal and the thoracic organs. It may remain undetected into adulthood until an acute medical emergency results in diagnostic imaging. This report presents a challenging case of left-sided acute appendicitis in a 45-year-old man with SIT. CASE REPORT A 45-year-old man with a medical history of gastroesophageal reflux disease, class 2 obesity, prediabetes, and elevated low-density lipoprotein cholesterol presented with severe acute abdominal pain localized in the left lower quadrant with localized tenderness, nausea, and 2 episodes of non-bloody and non-bilious emesis that started a day before the clinical encounter. Computed tomography of the abdomen and pelvis revealed previously undiagnosed congenital SIT. In addition, physical, laboratory, and radiological findings suggested early acute appendicitis with no evidence of complications. Hence, the patient was managed with an emergent laparoscopic appendectomy. Acute appendicitis was confirmed in the post-surgery histopathological examination. The post-surgery recovery was uneventful, and the patient was discharged home on the second postoperative day. CONCLUSIONS This report highlights that SIT may remain undiagnosed into adulthood and poses a challenge in the diagnosis of left-side appendicitis due to atypical symptom presentation, supporting the findings of previous case reports. Therefore, the inclusion of left-sided acute appendicitis in the differential diagnosis of abdominal pain in the left lower quadrant is warranted.

Situs inversus totalis in an asymptomatic adolescent - importance of patient education: A case report

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 previously-diagnosed 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.

Laparoscopic common bile duct exploration to treat choledocholithiasis in situs inversus patients: A technical review

Situs inversus (SI) is a rare congenital condition characterized by a mirror-image transposition of the major visceral organs. Since the 1990s, more than one hundred SI patients have been reported to have successfully undergone laparoscopic cholecystectomy. In these cases, the major problem is to overcome is the left-right condition for right-handed surgeons. Laparoscopic common bile duct exploration (LCBDE), an alternative to treat patients with bile duct stones, has shown equivalent efficacy and is less likely to cause pancreatitis than endoscopic retrograde cholangiopancreatography. Recent updated meta-analyses revealed that a shorter postoperative hospital stay, fewer procedural interventions, cost-effectiveness, a higher stone clearance rate, and fewer perioperative complications are additional advantages of LCBDE. However, the technique is technically demanding, even for skilled laparoscopic surgeons. Conducting LCBDE in patients with difficult situations, such as SI, is more complex than usual. We herein review published SI patients with choledocholithiasis treated by LCBDE, including our own experience, and this paper focuses on the technical aspects.
