RESUMEN
A 66-year-old Japanese woman was admitted to our hospital for jaundice. Abdominal computed tomography(CT) showed dilatation of the intra- and extra-hepatic bile duct, and a hypovascular lesion measuring 30mm in diameter in the head of the pancreas. This tumor was in contact with the(superior mesenteric vein: SMV)and(inferior vena cava: IVC), but there were no obvious signs of invasion. Upper gastrointestinal endoscopy showed obstruction of the duodenum. We chose to perform an upfront surgery, considering the patient's general condition being stable and the difficulties associated with endoscopic biliary drainage. During surgery, stiff attachment between the tumor and IVC was identified and wedge resection of the IVC wall was performed. SMV resection and end-to-end reconstruction were also carried out. Pathological studies of the surgical specimen revealed direct invasion by the pancreatic adenocarcinoma into the adventitia of the IVC. The postoperative course was uneventful, and the patient was discharged from the hospital on the 27th postoperative day; she underwent adjuvant chemotherapy(S-1 100mg/day)and is still alive without tumor recurrence, 21 months after surgery. Cases of resected pancreatic adenocarcinoma directly invading the IVC are rare. In this case, pancreaticoduodenectomy along with wedge resection of the IVC wall could safely be performed, and no complications were observed. There is a need for further accumulation of similar cases.

INTRODUCTION: Postoperative chronic pain is an important outcome of hernia surgery. In laparoscopic hernia surgery, either fixation outside the trapezoid of disaster or no fixation is recommended to avoid postoperative pain. To avoid recurrence are transabdominal preperitoneal (TAPP) hernia repair, the myopectineal orifice must be covered with mesh during TAPP, but lifting or shrinking of the mesh can lead to recurrence. The aim of this study was to evaluate the feasibility of a novel technique for mesh fixation to prevent the mesh from lifting off. METHODS: After the preperitoneal space was created during TAPP, the anatomy of the lateral cutaneous nerve of the thigh or the femoral branch of the genitofemoral nerve within the trapezoid of disaster was checked. The mesh was tacked at the trapezoid of disaster without nerve injury, and the mesh was fixed with circumferential tacking. We call this procedure secure tacking against recurrence (STAR). We treated 391 adult patients (478 hernias) with TAPP repair; novel tacking was used in some patients (STAR group, 236 hernias). The results of the STAR group were retrospectively compared with those of patients in whom we did not use this novel tacking (conventional group, 242 hernias). RESULTS: There was no postoperative chronic pain in either group. There were no cases of hernia recurrence in the STAR group, but there were four cases of hernia recurrence in the conventional group (0% vs 1.7%, P = 0.047). These four recurrences consisted of indirect hernia and mesh lifting on the lateral side. CONCLUSION: The STAR procedure is feasible and safety as a standard procedure for securing the mesh during TAPP.
