RESUMO
BACKGROUND: Right hepatectomy (RH) instead of right posterior sectionectomy (RPS) is commonly performed for hepatocellular carcinoma (HCC) in cirrhotic livers located lateral to the right hepatic vein in order to ensure adequate resection margin. This potentially increased the risk of postoperative liver failure. This study aims to compare survival outcomes and surgical morbidities between RH and RPS. METHODS: All patients between 2003 and 2013 with resection for solitary HCC in cirrhotic livers at segment 6/7 were reviewed. Baseline demographics, liver function, perioperative outcomes, and overall (OS) and disease-free survival (DFS) were compared between RH and RPS. RESULTS: Eighty-one patients were included in this study. Thirty-two patients had RH and forty-nine with RPS were selected as controls. Majority of the HCC patients (91.4 %) suffered from chronic hepatitis B. There was no significant difference in age, gender and Child-Pugh grade between the two groups. The median tumour size of RH group was 6 vs. 4 cm in the RPS group (p < 0.0001). Both groups had no statistical difference in resection margin and their associated morbidities. The 5-year OS for RH and RPS was 76 and 83.8 %, respectively (p = 0.766), whereas their corresponding DFS was 52.6 and 52.2 % (p = 0.859). Despite the discrepancy of tumour size among the two groups, there was no statistical difference in subgroup analysis based on their corresponding stage of disease. CONCLUSION: RPS can achieve similar OS and DFS as RH for HCC, and should be considered as the treatment of choice in order to optimise the postoperative remnant parenchymal liver functions.

Acute ischemic proctitis is a rare pathological condition. We report here a patient presented with massive rectal haemorrhage from a bleeding vessel superimposed on an underlying pathology of ischemic proctitis. This case report illustrates the difficulties in making the clinical distinction between ischemic proctitis and other pathological entities. We also discussed the beneficial role of arteriogram with embolotherapy as an effective therapeutic measure in the management of lower gastrointestinal bleeding. The literature on the subject is reviewed.

BACKGROUND: Little is known about whether hepatitis B surface antigen (HBsAg) seroconversion (SC) contributes to any survival benefits for patients with hepatocellular carcinoma (HCC). METHODS: All patients with hepatitis B-related HCC and HBsAg seroclearance between 1989 and 2013 were identified. Case- and control-groups were matched according to their stage of disease and mode of treatment. Baseline demographics, liver function, and overall survivals (OS) were compared between these two groups. RESULTS: Thirty-nine HCC cases with HBsAg SC were identified, and 312 non-seroconversion (NSC) HCC cases were matched. Forty-eight percent of patients had curative resections, 14% were treated with ablation and 38% were for palliation. Age of patients in SC group was older than those in NSC group (P=0.026). Although there was significantly better liver function in SC vs. NSC groups in terms of bilirubin (P=0.027), albumin (P=0.003), AST (P=0.001) and ALT (P<0.001), there was no overall difference in Child-Pugh grade among the two groups. In regarding tumour pathology, SC commonly presented with solitary tumour nodule as compared to multiple nodules in NSC (P=0.027), and was also frequently associated with a normal background liver parenchyma (P<0.001). Although no survival benefit was confirmed in log-rank analysis between SC and NSC, the absolute 5-year survival of SC group was better in resection (72.2% vs. 55.3%), ablation (83.3% vs. 57.4%) and palliation (24.4% vs. 14.4%). CONCLUSIONS: HCC patients with HBsAg SC are associated with a better background liver parenchyma and function, and might contribute to an improved long-term survival.
RESUMO
INTRODUCTION: The aim of this population-based study was to assess the incidence, mechanisms, management and outcome of patients who sustained pancreatic trauma in Scotland over the period 1992-2002. METHODS: The Scottish Trauma Audit Group database was searched for details of any patient with pancreatic trauma. RESULTS: About 111 of 52,676 patients (0.21%) were identified as having sustained pancreatic trauma. The male-to-female ratio was 3:1, with a median age of 32 years. Blunt trauma accounted for 66% of injuries. Road traffic accidents were the most common mechanism of injury (44%), followed by assaults (35%). Thirty-four patients (31%) were haemodynamically unstable on arrival at hospital. Pancreatic trauma was associated with injuries to the chest (56%), head (30%) and extremities (30%); 73% of patients had other intra-abdominal injuries. Of those who left the emergency department alive, at least 77% required a laparotomy. The mortality rate (46%) was directly proportional to the number of injuries sustained (P < 0.05) and was higher in patients with increasing age (P < 0.05), haemodynamic instability (P < 0.05) and blunt trauma (P < 0.05). CONCLUSIONS: Pancreatic trauma is rare in Scotland but is associated with significant mortality. Outcome was worse in patients with advanced age, haemodynamic instability, blunt trauma and multiple injuries.

BACKGROUND: Below knee amputation (BKA) is often required in patients with critical limb ischemia. When such a procedure fails, an above knee revision (AKA) is required. This can cause further complications in this group of patients, who already have a high incidence of medical co-morbidities. METHODS: Case records of 47 patients (51 procedures performed) with BKA for peripheral vascular diseases during a 4-year period were reviewed. Clinical factors were analyzed using bi- and multi-variate analysis against the procedure outcome. Degree of social deprivation was evaluated with DEPCAT score in relation to amputation failure. Each arterial segment of the pre-operative arteriograms was scored based on a 3-point scoring system (0=normal, 1=stenosis, and 2=cclusion). With the assignment of an arbitrary weight for each segment, a total arterial score (TAS) was derived for each patient. RESULTS: Eighteen percent of BKA (n=9) failed. Absence of popliteal pulse (failure vs. success: 100% vs. 63%, P=0.04), calf rest pain (67% vs. 20%, P=0.01), combination of calf rest pain and feet tissue loss (CRPFTL; 67% vs. 3%, P=0.00), postoperative stump trauma (44% vs. 10%, P=0.03), and wound infection (WI; 89% vs. 26%, P=0.00) were factors associated with the failure of a BKA in bivariate analysis. Using multiple logistic regression, WI (OR=14) and CRPFTL (OR=47) were found to be independent predictors for the outcome of BKA. No statistical significance was found between the DEPCAT score and the failure rate. TAS was significantly higher in the failure group (median=17 vs. 9; P=0.00). CONCLUSIONS: This study suggests that CRPFTL and postoperative WI are predictor variables for the failure of a BKA. In addition, there is the potential role of arteriogram scoring in predicting the outcome of a BKA.
