The barcelona clinic liver cancer (BCLC) staging system has been approved as guidance for hepatocellular carcinoma (HCC) treatment guidelines by the main Western clinical liver associations. According to the BCLC classification, only patients with a small single HCC nodule without signs of portal hypertension or hyperbilirubinemia should undergo liver resection. In contrast, patients with intermediate-advanced HCC should be scheduled for palliative therapies, even if the lesion is resectable. Recent studies report good short-term and long-term outcomes in patients with intermediate-advanced HCC treated by liver resection. Therefore, this classification has been criticised because it excludes many patients who could benefit from curative resection. The aim of this review was to evaluate the role of surgery beyond the BCLC recommendations. Safe liver resection can be performed in patients with portal hypertension and well-compensated liver function with a 5-year survival rate of 50%. Surgery also offers good long-term result in selected patients with multiple or large HCCs with a reported 5-year survival rate of over 50% and 40%, respectively. Although macrovascular invasion is associated with a poor prognosis, liver resection provides better long-term results than palliative therapies or best supportive care. Recently, researchers have identified several genes whose altered expression influences the prognosis of patients with HCC. These genes may be useful for classifying the biological behaviour of different tumours. A revision of the BCLC classification should be introduced to provide the best treatment strategy and to ensure the best prognosis in patients with HCC.
Cytospin preparations were made from 102 serous effusions for immunocytochemical staining using a panel of monoclonal antibodies including a new monoclonal antibody Ber-EP4. On cytological examination, 32 fluids were reported to contain tumour cells consistent with metastatic adenocarcinoma; 66 contained benign cells only and three were reported to contain cells suspicious of malignancy. One effusion contained tumour cells consistent with malignant mesothelioma. Positive staining of the tumour cells with Ber-EP4 was observed in the 32 effusions (100%) which contained adenocarcinoma cells. No staining of the mesothelial cells in these 32 specimens was observed. Carcinoembryonic antigen, epithelial membrane antigen Ca2 and CD15 staining of tumour cells was noted in 53%, 50%, 50% and 9% of these cases, respectively. None of the mesothelial cells in the benign effusions stained with Ber-EP4. Nor did the malignant mesothelial cells in the only case of malignant mesothelioma. These findings suggest that Ber-EP4 is a valuable addition to antibodies available for the differential diagnosis of mesothelial cells and adenocarcinoma cells in serous effusions.
In patients undergoing surgery for colorectal liver metastases after chemotherapy, contrast-enhanced intraoperative ultrasonography improved both the sensitivity of intraoperative ultrasonography to detect liver metastases and the R0 hepatic resection rate.
Background Inguinoscrotal herniation of the bladder is a rare clinical entity, with a frequency between 0.5% and 4% of all inguinal hernias. The bladder can partially or entirely herniate into the inguinal canal; when the whole bladder and ureters migrate into the scrotum, it may cause urinary disorders. Case Presentation A 62-year-old male patient presented with urinary disorders and right-sided inguinoscrotal hernia. Under clinical suspicion of bladder involvement in the inguinal canal, abdominal and pelvic computed tomography (CT) scan with endovenous contrast was performed, revealing a right inguinoscrotal hernia, containing the whole urinary bladder and the right pelvic ureter. Without violating the urinary bladder wall integrity, the content of the hernial sac was reduced into the abdominal cavity. Hernioplasty was performed by means of Lichtenstein's method. Conclusions Ureteral involvement should be suspected when a clinical inguinal hernia is diagnosed concurrently with unexplained hydronephrosis, renal failure, or urinary tract infection, as in the case described. When suspected, the preoperative diagnosis, particularly with CT scan, is essential to avoid complications and to reduce risk of bladder and ureter injuries during hernia repair.
Background
Ileus is common after elective colorectal surgery, and is associated with increased adverse events and prolonged hospital stay. The aim was to assess the role of non‐steroidal anti‐inflammatory drugs (NSAIDs) for reducing ileus after surgery.
Methods
A prospective multicentre cohort study was delivered by an international, student‐ and trainee‐led collaborative group. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The primary outcome was time to gastrointestinal recovery, measured using a composite measure of bowel function and tolerance to oral intake. The impact of NSAIDs was explored using Cox regression analyses, including the results of a centre‐specific survey of compliance to enhanced recovery principles. Secondary safety outcomes included anastomotic leak rate and acute kidney injury.
Results
A total of 4164 patients were included, with a median age of 68 (i.q.r. 57–75) years (54·9 per cent men). Some 1153 (27·7 per cent) received NSAIDs on postoperative days 1–3, of whom 1061 (92·0 per cent) received non‐selective cyclo‐oxygenase inhibitors. After adjustment for baseline differences, the mean time to gastrointestinal recovery did not differ significantly between patients who received NSAIDs and those who did not (4·6 versus 4·8 days; hazard ratio 1·04, 95 per cent c.i. 0·96 to 1·12; P = 0·360). There were no significant differences in anastomotic leak rate (5·4 versus 4·6 per cent; P = 0·349) or acute kidney injury (14·3 versus 13·8 per cent; P = 0·666) between the groups. Significantly fewer patients receiving NSAIDs required strong opioid analgesia (35·3 versus 56·7 per cent; P < 0·001).
Conclusion
NSAIDs did not reduce the time for gastrointestinal recovery after colorectal surgery, but they were safe and associated with reduced postoperative opioid requirement.
