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 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.
LAG with D2 LND could be considered an accessible, safe, and curative procedure for advanced GC patients with SIT.
Core Tip: Laparoscopic surgery in situs inversus totalis (SIT) patients with gastric cancer (GC) is exceedingly rare and challenging. We report the cases of two advanced GC patients with SIT who successfully underwent laparoscopy-assisted gastrectomy with D2 lymphadenectomy. In this report, we share our experience and review the literature in the previous 11 years to summarize the general consensus on laparoscopic radical gastrectomy in patients with SIT.
