Safety and Feasibility of Laparoscopic Anatomical Liver Resection for Hepatocellular Carcinoma: A Propensity Score-matched Study.

BACKGROUND/AIM: Laparoscopic anatomical liver resection (LAR) for hepatocellular carcinoma (HCC) is technically demanding. Therefore, this study aimed to compare the perioperative and long-term oncological outcomes of LAR and open anatomical liver resection (OAR) for HCC. PATIENTS AND METHODS: We retrospectively analyzed 460 consecutive patients who underwent anatomical liver resection as the initial treatment for primary HCC between January 2010 and February 2024. Patients were categorized into the LAR and OAR groups, and surgical outcomes between the groups were compared using 1:1 propensity score matching (PSM). RESULTS: After PSM, the LAR and OAR groups included 100 patients each. The LAR group exhibited significantly less blood loss (80 vs. 436 ml; p<0.0001), lower transfusion rates (0% vs. 12%; p=0.0002), shorter operative time (345 vs. 398 min; p=0.0009), lower postoperative morbidity rates (6% vs. 34%; p<0.0001), and shorter postoperative hospital stay (8 vs. 15 days; p<0.0001) than the OAR group. The 1-, 3-, and 5-year overall survival rates were 97.7%, 96.2%, and 89.7%, respectively, in the LAR group and 98.0%, 92.7%, and 88.4%, respectively, in the OAR group (p=0.5874). The 1-, 3-, and 5-year recurrence-free survival rates were 93.2%, 75.7%, and 60.7%, respectively, in the LAR group and 86.0%, 64.5%, and 59.1%, respectively, in the OAR group (p=0.2314). CONCLUSION: LAR showed improvements in perioperative complications, reduced postoperative hospital stay, and comparable recurrence-free and overall survival rates with those of OAR. Therefore, LAR for HCC is considered safe, feasible, and oncologically acceptable in selected patients.

Hand-assisted laparoscopic surgery for Bochdalek hernia in an adult patient with a history of laparotomy: A case report.

INTRODUCTION: Bochdalek hernia (BH) is a congenital diaphragmatic hernia that generally occurs in infants and is rarely seen in adults. Surgical repair of BH is recommended, but the approach for repairing BH should be selected carefully in individual cases. It is well known that hand-assisted laparoscopic surgery (HALS) has the advantage of preserving tactile sensation compared with standard laparoscopic surgery. We describe an adult patient with a history of abdominal incisional hernia who developed BH that was treated safely by HALS. PRESENTATION OF CASE: An 87-year-old woman was admitted to our hospital with nausea. She had a history of right hemicolectomy and repair of an abdominal incisional hernia using mesh at 5 years after hemicolectomy. Chest and abdominal computed tomography revealed herniation of the gastric corpus through the left posterior diaphragm. BH was diagnosed and hernia repair by HALS was selected as the approach because dense adhesions were expected in the abdominal cavity. The operation was performed safely and her postoperative course was uneventful. CONCLUSION: HALS was useful, especially when removing adhesions around the hernial orifice. HALS is a feasible approach for BH and should be considered as one of the options in patients with a history of previous abdominal surgery.

A foot ulcer caused by the use of an angio-seal arterial closure device after percutaneous transluminal angioplasty: a case report.

Although the Angio-Seal arterial closure device is widely used for preventing bleeding and facilitating early ambulation after arterial puncture, it is also associated with unique complications, such as stenosis, occlusion, or peripheral embolism. We report the first case of a foot ulcer that developed 70 days after an Angio-Seal application. The collagen sponge component accidently positioned itself in the arterial lumen and was not absorbed. A foreign body reaction was observed microscopically. In patients with arteriosclerosis, the Angio-Seal device should be used carefully; post procedural monitoring is necessary after implantation.
