CT guided percutaneous transhepatic microwave ablation for primary liver cancer in segment 9 / 中华肝胆外科杂志

Objective:To study the efficacy and safety of CT guided percutaneous transhepatic microwave ablation (PTPMWA) for primary liver cancer (PLC) in liver segment 9.Methods:A retrospective study was conducted on PLC patients between October 2013 and March 2019 at Dongguan People’s Hospital, Southern Medical University. Of 41 patients who entered into the study, there were 36 males and 5 females, with an average age of 59.1 years. These patients were diagnosed to have PLC in segment 9. The surgical related data and follow-up results were collected and analyzed.Results:All patients enrolled in the study completed the treatment procedure. CT scan was performed immediately after ablation which showed that the tumor areas to be completely covered by ablation. The duration of operation ranged from 45 to 260 (mean 91) min. The amount of bleeding during treatment was 1.0 to 5.0 (mean 1.4) ml. The complete response rate was 97.6% (40 patients) and the partial response rate was 2.4% (1 patient). The cumulative survival rates at 1, 2, 3, 4 and 5 years were 95.1%, 85.4%, 75.3%, 45.2% and 45.2%, respectively. Only 4 patients (9.8%) developed recurrence after treatment. The timings of recurrence were 1, 6, 13 and 67 months after treatment, respectively. The recurrent lesions were ablated again and complete response was obtained in all patients. There were no serious problems related to complications from ablation. The rate of postoperative complication was 7.3% (3 patients).Conclusion:PTPMWA is a novel treatment for patients with PLC in liver segment 9, the advantages of this treatment include good safety, high efficacy, low complications and local recurrence. The treatment is worthy of further future studies.

Experience of pancreaticoduodenectomy and the diagnosis of carcinoma of the papilla of Vater / 中华肝胆外科杂志

Objective To summarize our experience in the diagnosis and treatment of carcinoma of the papilla of Vater (CPV).Methods From April 2005 to May 2012,21 consecutive patients were enrolled in Dongguan Affiliated Hospital of Southern Medical University.The clinical characteristics,diagnosis,surgical data and follow-up results of these patients were retrospectively analyzed.Results Painless jaundice was the primary symptom in 18 patients.An elevated CEA level was observed in 3 patients preoperatively,while CA19-9 was increased in 10 patients.17 patients with periampullary tumors were detected by MRCP or CT,and in 12 patients,they were detected by ultrasound examination.Gastroscopy was performed in 16 patients,among whom 8 patients were diagnosed with neoplasm of the duodenal papilla initially,and 5 patients were ultimately diagnosed with CPV by pathological examination after biopsy.All the 21 patients were successfully treated with pancreaticoduodenectomy.8 patients developed postoperative complications.No death occurred in the perioperative period.The complications included pancreatic fistula (2 patients),gastroparesis (2 patients),incisional infection (2 patients),gastrointestinal hemorrhage (1 patient) and concurrent gastrointestinal and intraperitoneal haemorrhage (1 patient).A reoperation consisting of pancreaticoduodenal repair and drainage was performed in 1 patient.3 patients underwent adjuvant chemotherapy.Long-term follow up was obtained in 18 patients.The 1-year,3-year and 5-year survival rates were 80.9％,66.7％ and 47.6％,respectively.The longest overall survival was 152 months.Conclusions Early diagnosis of CPV was feasible.Pancreaticoduodenectomy as a treatment strategy for this cancer was safe and effective.

Surgical therapy for hepatocellular carcinoma with right diaphragmatic invasion / 中华肝胆外科杂志

Objective To review the indications,surgical methods,and matters which need attention in partial right diaphragmatic resection,and to summarize our experience of surgical therapy for hepatocellular carcinoma with right diaphragmatic invasion.Methods The clinical data of 27 patients with hepatocellular carcinoma which had invaded the diaphragm and had received partial right diaphragmatic resection and partial hepatectomy in our hospital from September 2008 to September 2012 were retrospectively analyzed.Results The operations were all performed successfully.The tumor diameter ranged from 5.0 to 15.0 cm (average 8.5 cm).The area of right diaphragm which was resected ranged from 9.0 to 50.0 cm2 (average 28.5 cm2).The operation time was 110～250 min (average 165 min),and blood loss was 450～2600 ml (average 870 ml).Diaphragmatic invasion was confirmed by postoperative histopathology in 9 patients (33.3％).A small quantity of right thoracic effusion was detected in all the cases postoperatively.Other complications included hepatic insufficiency in 4 patients and early postoperative bleeding,upper gastrointestinal bleeding,biliary fistula,and infection under the diaphragm in 1 case each.All patients recovered after conservative treatment.There was no perioperative death.19 patients received other postoperative adjuvant treatment while 6 patients refused further treatment and 2 patients were lost to follow-up.The 0.5-,1-,2,and 3 year survival rates after operation were 92.6％,81.5％,51.9％ and 33.3％ respectively.Conclusions Right diaphragmatic invasion is not a contraindication to surgery.Right diaphragmatic resection was safe and feasible,and postoperative long-term survival was satisfactory.

Management of main hepatic vein injury in hepatectomy for hepatic neoplasm of segment Ⅷ / 中华肝胆外科杂志

Objective To summarize the experience in management of main hepatic vein injury due to hepatectomy for hepatic neoplasm of segment Ⅷ. Methods Clinical data of 64 patients suffering from main hepatic vein injury due to hepatectomy of hepatic neoplasm of segment Ⅷ in our hospital from October 1996 to October 2008 were retrospectively analyzed. Results Both the main trunks of the middle and right hepatic vein were injured in 34 patients, single right hepatic vein in 13 and middle hepatic vein in 17. In these patients with hepatic vein injury, the main trunk of the hepatic vein was repaired in 39, vessels ligated in 12 and direct liver wound surfaces sutured in 12. The hepatectomy and hemostasis were successfully performed during operation in all patients. After operation, 3 patients had active bleeding and 2 patients were reoperated on to sew up the bleeding points by wadding with the gelatin sponge and discharged after rehabilitation. One patient gave up treatment and was discharged automatically. Conclusion Main hepatic vein injury in hepatectomy of hepatic neoplasm of segment Ⅷ can be managed effectively by hepatic vein repair, hepatic vein ligation and suture of the liver section that can be chosen to control the bleeding of hepatic vein injury according to the actual conditions.
