RESUMO
BACKGROUND: Incisional hernia (IH) is common after major abdominal surgery; however, the incidence after hepatectomy for cancer has not been described. We analyzed incidence of and risk factors for IH after hepatectomy for colorectal liver metastases (CLM). METHODS: Patients who underwent open hepatectomy with midline or reverse-L incision for CLM at a single institution between 2010 and 2018 were retrospectively analyzed. Postoperative CT scans were reviewed to identify IH and the time from hepatectomy to hernia. Cumulative IH incidence was calculated using competing risk analysis. Risk factors were assessed using Cox proportional hazards model analysis. The relationship between IH incidence and preoperative body mass index (BMI) was estimated using a generalized additive model. RESULTS: Among 470 patients (median follow-up: 16.9 months), IH rates at 12, 24, and 60 months were 41.5%, 51.0%, and 59.2%, respectively. Factors independently associated with IH were surgical site infection (HR: 1.54, 95% CI 1.16-2.06, P = 0.003) and BMI > 25 kg/m2 (HR: 1.94, 95% CI 1.45-2.61, P < 0.001). IH incidence was similar in patients undergoing midline and reverse-L incisions and patients who received and did not receive a bevacizumab-containing regimen. The 1-year IH rate increased with increasing number of risk factors (zero: 22.2%; one: 46.8%; two: 60.3%; P < 0.001). Estimated IH incidence was 10% for BMI of 15 kg/m2 and 80% for BMI of 40 kg/m2. CONCLUSION: IH is common after open hepatectomy for CLM, particularly in obese patients and patients with surgical site infection. Surgeons should consider risk-mitigation strategies, including alternative fascial closure techniques.

BACKGROUND: Ampullary adenocarcinoma (AAC) is a rare neoplasm that accounts for only 0.2% of all gastrointestinal cancers. Its incidence rate is lower than 6 cases per million people. Different prognostic factors have been described for AAC and are associated with a wide range of survival rates. However, these studies have been exclusively conducted in patients originating from Asian, European, and North American countries. AIM: To evaluate the histopathologic predictors of overall survival (OS) in South American patients with AAC treated with curative pancreaticoduodenectomy (PD). METHODS: We analyzed retrospective data from 83 AAC patients who underwent curative (R0) PD at the National Cancer Institute of Peru between January 2010 and October 2020 to identify histopathologic predictors of OS. RESULTS: Sixty-nine percent of patients had developed intestinal-type AAC (69%), 23% had pancreatobiliary-type AAC, and 8% had other subtypes. Forty-one percent of patients were classified as Stage I, according to the AJCC 8th Edition. Recurrence occurred primarily in the liver (n = 8), peritoneum (n = 4), and lung (n = 4). Statistical analyses indicated that T3 tumour stage [hazard ratio (HR) of 6.4, 95% confidence interval (CI) of 2.5-16.3, P < 0.001], lymph node metastasis (HR: 4.5, 95%CI: 1.8-11.3, P = 0.001), and pancreatobiliary type (HR: 2.7, 95%CI: 1.2-6.2, P = 0.025) were independent predictors of OS. CONCLUSION: Extended tumour stage (T3), pancreatobiliary type, and positive lymph node metastasis represent independent predictors of a lower OS rate in South American AAC patients who underwent curative PD.
RESUMO
Since the inception of the associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure, many centres have used this technique for patients who would otherwise be considered unresectable due to insufficient future liver remnant. In this report, we presented the case of a paediatric patient with recurrent hepatocellular carcinoma who underwent monosegment ALPPS (M-ALPPS) hepatectomy preserving segment 1 as the sole liver remnant using indocyanine green (ICG) as a fluorescence guide.
RESUMO
BACKGROUND: The standard treatment for ampullary adenocarcinoma is pancreaticoduodenectomy. Identification of preoperative risk factors might help the clinician to select patients fit for resection and potentially decrease morbidity and mortality after PD. We conducted a cohort study to determine the preoperative factors related to 90-day severe morbidity and mortality after PD. METHODS: We conducted a retrospective cohort study in patients with a diagnosis of ampullary adenocarcinoma who underwent an open PD between January 2010 and December 2019 at our tertiary centre. RESULTS: Independent preoperative predictors of mortality were the albumin-bilirubin (ALBI) grade 3 (OR: 21.7; CI 95: 2.1-226.9; p=0.01) and the estimated glomerular filtration rate (eGFR) <90 mL/min/1.73 m2 (OR: 17.7; CI 95: 1.8-172.6; p=0.013). The eGFR <90 mL/min/1.73 m2 (OR = 6.6; CI 95: 1.9-23.4; p=0.003) and prothrombin time (OR = 1.5; CI 95; 1.1-2.1; p=0.005) were independent predictors for severe morbidity. CONCLUSION: These findings suggest that baseline renal function measured by the eGFR and liver function categorized with the ALBI grading are predictors of severe morbidity and mortality. Thus, they should be considered when selecting patients for PD or the use of neoadjuvant treatments. Further research is warranted.
RESUMO
BACKGROUND: Posthepatectomy decompensation remains a frequent and poor outcome after hepatectomy, but its prediction is still inaccurate. Liver stiffness measurement can predict posthepatectomy decompensation, but there is a so-called "gray zone" that requires another predictor. Because splenomegaly is an objective sign of portal hypertension, we hypothesized that spleen volumetry could improve the identification of patients at risk. METHODS: Patients with hepatocellular carcinoma who underwent hepatectomy in our tertiary center between August 2014 and December 2017 were reviewed. The primary endpoint was to determine if the spleen volumetry and liver stiffness measurement were independent predictors of posthepatectomy decompensation, and secondarily, to determine if they were synergistic through a theoretic predictive model. RESULTS: One hundred and seven patients were included. The median follow-up time was 3 months (3-5). Postoperative 90-day mortality was 4.7%. By multivariate analysis, liver stiffness measurement and spleen volumetry predicted posthepatectomy decompensation. The liver stiffness measurement had a cutoff point of 11.6 kPa (area under receiver operating curve = 0.71 confidence interval 95% 0.71-0.88, sensitivity: 89%, specificity: 47%). The spleen volumetry cutoff point was 381.1 cm3 (area under receiver operating curve = 0.78, 95% confidence interval 0.77-0.93, sensitivity: 55%, specificity: 91%). The spleen volumetry improved prediction of posthepatectomy decompensation, because use of the spleen volumetry increased sensitivity (from 62% to 97%) and the negative predictive value (from 96% to 100%) along with a negligible decrease in specificity (from 96.7 to 93.4) and positive predictive value (from 64% to 59%) (P = .003). CONCLUSION: Spleen volumetry (>380 cm3) and liver stiffness measurement (>12 kPa) are non-invasive, independent, and synergistic tools that appear to be able to predict posthepatectomy decompensation. The importance of this finding is that these measurements may help to anticipate posthepatectomy decompensation and may possibly be used to direct alternative treatments to resection.

A 3-year-old female was treated with neoadjuvant chemotherapy (NACT) for a PRETEXT IV hepatoblastoma. POST-TEXT IV findings merited a liver transplant (LT), but multiple limitations precluded it. The initial future liver remnant (FLR) was small (21.3%). Monosegment 6 ALPPS was a rational approach given that the inferior right hepatic vein (IRHV) provided adequate outflow. Therefore, the procedure was performed after parental informed consent. On PO15 of the first stage, FLR had reached 32.6% and then the second-stage was carried out. The patient was discharged on POD 31, and she is about to reach the 5-year disease-free survival milestone.
