Curative surgery for multiple hepatocellular carcinomas after lenvatinib plus transarterial chemoembolization: a case report.

Surgical therapy following lenvatinib (LEN) plus transarterial chemoembolization (TACE) is a useful therapeutic option for intermediate-stage hepatocellular carcinoma (HCC). A 66-year-old man with a history of hepatitis C was detected four masses in the caudate lobe and segment 6/7 of the liver, with a maximum lesion diameter of 14 cm by computed tomography. The patient was diagnosed with intermediate-stage HCC and received LEN plus TACE. After resuming LEN for 8 weeks, computed tomography showed weakened stained areas of the tumors, and no new lesions. Thus, the patient was evaluated as having a partial response in the modified Response Evaluation Criteria in Solid Tumors. The patient underwent hepatic caudate lobectomy, partial hepatectomy of S6/7, and S6 microwave coagulation therapy for radical resection. The patient is currently alive and recurrence-free at 12 months postoperatively. In patients with multiple HCC lesions, hepatic resection combined with local therapy might be an effective treatment option.

Surgical treatment of hepatocellular carcinoma after Fontan operation: three case reports and review of the literature.

We herein describe three patients with Fontan-associated liver disease who developed hepatocellular carcinoma (HCC). The first patient was a 28-year-old woman who had undergone the Fontan operation (FO) at the age of 4 years. She was diagnosed with HCC (cT4aN0M0, Stage IVA, UICC 8th edition), for which she underwent extended posterior right sectionectomy and partial hepatectomy of S2. She developed recurrence of peritoneal dissemination after 12 months, and she was alive 18 months after surgery. The second patient was a 43-year-old man who had undergone the FO at the age of 3 years. He was diagnosed with HCC (cT2N0M0, Stage II), for which he underwent laparoscopic-assisted partial hepatectomy of S3. He remained free from recurrent HCC for 17 months. The third patient was a 21-year-old woman who had undergone the FO at the age of 3 years. She was diagnosed with HCC (cT3N0M0, Stage III), for which she underwent laparoscopic-assisted partial hepatectomy of S2 and S4. She remained free from recurrent HCC for 30 months. We reviewed 18 surgical cases of HCC arising from Fontan-associated liver disease, including our 3 cases, and found that a high preoperative alpha-fetoprotein concentration might be a predictor of HCC recurrence.

Pancreatic-pleural fistula from tail pseudocyst in a patient with pancreatic head cancer: a case report.

A 76-year-old man was diagnosed with resectable pancreatic ductal adenocarcinoma (PDAC) of the pancreatic head. Concurrently, the patient had an approximately 2-cm cystic mass originating from the pancreatic tail. After preoperative chemotherapy for the resectable PDAC, the patient is presented with dyspnea and lower left thoracic pain. Chest X-ray revealed massive left pleural effusion, and laboratory analysis of the pleural fluid showed a very high amylase level. Computed tomography confirmed a fistula directly connecting the pancreatic tail pseudocyst to the left diaphragm. These findings suggested pancreatic-pleural fistula (PPF) from the pancreatic tail to the left pleura. Medical treatments of thoracic drainage, endoscopic pancreatic ductal drainage, and antibiotics were unsuccessful; therefore, a distal pancreatectomy, fistula closure, and thoracoscopic pleural decortication were performed before the pancreaticoduodenectomy for the PDAC. After surgery, the pleural effusion resolved and the symptoms were improved immediately. PPF is an uncommon complication in which pancreatic enzymes drain directly into the pleural cavity. Herein, we present a rare case of PPF after preoperative chemotherapy for PDAC with a review of the literature.

Impact of aspartate aminotransferase-to-platelet ratio index based score to assess posthepatectomy liver failure in patients with hepatocellular carcninoma.

BACKGROUND: Posthepatectomy liver failure (PHLF) is a life-threatening complication following hepatic resection. The aspartate aminotransferase-to-platelet ratio index (APRI) is a non-invasive model for assessing the liver functional reserve in patients with hepatocellular carcinoma (HCC). This study aimed to establish a scoring model to stratify patients with HCC at risk for PHLF. METHODS: This single-center retrospective study included 451 patients who underwent hepatic resection for HCC between 2004 and 2017. Preoperative factors, including non-invasive liver fibrosis markers and intraoperative factors, were evaluated. The predictive impact for PHLF was evaluated using receiver operating characteristic (ROC) curves of these factors. RESULTS: Of 451 patients, 30 (6.7%) developed severe PHLF (grade B/C). Multivariate logistic analysis indicated that APRI, model for end-stage liver disease (MELD) score, operating time, and intraoperative blood loss were significantly associated with severe PHLF. A scoring model (over 0-4 points) was calculated using these optimal cutoff values. The area under the ROC curve of the established score for severe PHLF was 0.88, which greatly improved the predictive accuracy compared with these factors alone (p < 0.05 for all). CONCLUSIONS: The scoring model-based APRI, MELD score, operating time, and intraoperative blood loss can predict severe PHLF in patients with HCC.

Unexpected Histopathological Diagnosis of Placental Transmogrification of the Lung after Bullectomy for Recurrent Spontaneous Pneumothorax: A Case Report and Literature Review.

We report a 33-year-old man who presented with recurrent right pneumothorax. Computed tomography (CT) showed the presence of a large bulla with a maximum diameter of 8 cm in the right middle lobe; he subsequently underwent bullectomy. Histopathology revealed that pulmonary parenchyma adjacent to the bulla represented nodular proliferation of clear cells characterized by a papillary structure resembling placental chorionic villi. Immunohistochemically, clear cells were positive for CD10, suggesting placental transmogrification of the lung (PTL). We reviewed 36 surgical cases of PTL, and only 2 cases (5.6%), including our case, were operated for spontaneous pneumothorax. Bullous lesions secondary to PTL tend to appear as unilateral large cystic masses in non-upper lobes, which is atypical for primary spontaneous pneumothorax (PSP). Although PTL is considered a very rare cause of secondary pneumothorax, we must carefully differentiate this condition.

Laparoscopic delayed and interval appendectomy in the workstyle reform era.

PURPOSE: Excessive working hours have been reported to contribute to burnout among surgeons. In Japan, work-style reform is a problem that needs immediate attention. Acute appendectomy, which often occurs at nighttime, is one of the most common emergency surgeries. The feasibility of delayed and interval appendectomy remains to be investigated. METHODS: Two hundred forty-five consecutive patients who underwent laparoscopic appendectomy in our hospital were enrolled. They were divided into three groups: emergency appendectomy (immediate surgery, soon after the diagnosis [EA group], n = 153), delayed appendectomy (surgery during daytime the following day [DA group], n = 38) and interval appendectomy (antibiotics treatment followed by selective surgery three to four months later [IA group], n = 54). The clinical background and surgical outcomes were compared. Next, the residents' excess working time per month was calculated. RESULTS: The surgical outcomes (operation time, blood loss, length of hospital stay, postoperative complications) were similar between the EA and DA groups. However, no DA was performed during nighttime hours whereas 15.7% of EA was performed during nighttime hours (p = 0.0007). The surgical outcomes of the IA group were also comparable. The residents' excess working time declined following the introduction of DA and workstyle reform. CONCLUSION: Delayed and interval laparoscopic appendectomy are feasible, and can be performed to promote workstyle reform without impairing patient safety.
