Abstract
Hepatocellular carcinoma (HCC) is the sixth most common cancer and the third most common cause of cancer-related deaths worldwide. The Barcelona Clinic Liver Cancer (BCLC) classification has been endorsed as the optimal staging system and treatment algorithm for HCC by the European Association for the Study of Liver Disease and the American Association for the Study of Liver Disease. However, in real life, the majority of patients who are not considered ideal candidates based on the BCLC guideline still were performed hepatic resection nowadays, which means many hepatic surgeons all around the world do not follow the BCLC guidelines. The accuracy and application of the BCLC classification has constantly been challenged by many clinicians. From the surgeons’ perspectives, we herein put forward some comments on the BCLC classification concerning subjectivity of the assessment criteria, comprehensiveness of the staging definition and accuracy of the therapeutic recommendations. We hope to further discuss with peers and colleagues with the aim to make the BCLC classification more applicable to clinical practice in the future.

Abstract
OBJECTIVE The aim of this study was to investigate the prognostic value of tumor size alone on long-term survival and recurrence after curative resection for solitary hepatocellular carcinoma (HCC) without macroscopic vascular invasion. METHODS A single-center cohort of 615 patients with solitary HCC (a single tumor, without macroscopic vascular invasion or distant metastasis) undergoing curative hepatic resection from 2002 to 2010 was retrospectively studied. Using 2.0, 3.0, 4.0, 5.0, 8.0, and 10.0 cm as cut-off values of tumor size, the overall survival (OS) and recurrence-free survival (RFS) rates were compared between the groups of patients with tumor size up to a certain cut-off value and the groups of patients with tumor size above that cut-off value. Thus, multiple comparisons were done. The prognostic factors of OS and RFS were evaluated using univariate and multivariate analyses. RESULTS The median tumor size of all HCCs was 4.0 cm (range 0.9-22.0 cm). The in-hospital mortality rate was 1.0 %, and the overall morbidity rate was 22.3 %. The 1-, 3-, and 5-year OS rates were 96.0, 79.8, and 69.9 %, and the corresponding RFS rates were 83.6, 72.7, and 57.2 %, respectively. On univariate analyses, the 1-, 3-, and 5-year OS and RFS rates were significantly different between the individual two groups of patients as divided by the aforementioned different cut-off values of tumor sizes (all p < 0.05). However, when tumor size was put as a continuous variable into multivariate analysis, it was no longer an independent prognostic factor of OS or RFS after curative resection. CONCLUSIONS Tumor size did not independently affect long-term survival and recurrence after curative resection of solitary HCC without macroscopic vascular invasion. Therefore, there is no size limit that precludes hepatic resection for solitary HCC, provided the tumor is resectable.

Abstract
To investigate the appropriate cutoff point of CA19-9 for prognosis and other potential prognostic factors that may affect survival of patients with hilar cholangiocarcinoma (HC) after radical surgery. 168 patients who had undergone radical surgery for hilar cholangiocarcinoma and resultant macroscopic curative resection (R0 and R1) were discreetly selected for analyses. Categorized versions were used in univariate model to determine the appropriate cutoff point of CA19-9. CA19-9 and other clinicopathologic factors were analyzed for influence on survival by univariate and multivariate methods. The strongest univariate predictor among the categorized preoperative CA19-9 measures was CA19-9 less than 150 IU/L (P = 0.000). In univariate analysis, tumor size, Bismuth-Corlette classification, portal vein invasion, Lymph node metastasis, resection margin and preoperative CA19-9 levels were identified as significant prognostic factors. In multivariable analysis, lymph node metastasis, resection margin and preoperative CA19-9 levels were independent prognostic factors. our results demonstrated that preoperative CA19-9 levels was also an independent prognostic factor for hilar cholangiocarcinoma, and the most discriminative cutoff point of CA19-9 for prognosis proved to be at 150 U/ml.

Abstract
INTRODUCTION Hepatocellular carcinoma (HCC) occurring in pregnancy is quite rare. The prognosis is usually poor because of a delay in diagnosis. Reported cases of HCC in pregnancy are largely isolated with no large experience. Thus the effect of pregnancy on the prognosis of patients with HCC and the risk factors of developing HCC in pregnancy are not well documented. Our aim was to review our experience with management of four young pregnant women with HCC. PRESENTATION OF CASE Laboratory tests were performed before surgery. We analyzed the effects of age, hepatitis B surface antigens status, cirrhosis at presentation, gestational age of fetus, and maternal outcome. DISCUSSION Increase in alpha-fetoprotein (AFP) level was somewhat useful for diagnosis. Three patients died in 5 months, 6 months, and 24 months from HCC recurrence, and another patient is alive without disease 12 months postoperatively. CONCLUSION Surgery for HCC during pregnancy should be similar to that for non-pregnant women. Complete excision of tumor without termination of pregnancy provides the greatest chance of survival for women with HCC during pregnancy but depends on gestational age of the fetus. Adjuvant treatments are required to improve the long-term results of this type of surgery. The 28-week gestational week is a critical point of fetal maturation which is very important in deciding whether pregnancy should be terminated or not. The pregnancy was terminated in two of our patients when spontaneous rupture of HCC was diagnosed to save the mother's life.

Abstract
The present study focuses on the neuroprotective effect of glycyrrhizic acid (GA, a major compound separated from Glycyrrhiza Radix, which is a crude Chinese traditional drug) against glutamate-induced cytotoxicity in differentiated PC12 (DPC12) cells. The results showed that GA treatment improved cell viability and ameliorated abnormal glutamate-induced alterations in mitochondria in DPC12 cells. GA reversed glutamate-suppressed B-cell lymphoma 2 levels, inhibited glutamate-enhanced expressions of Bax and cleaved caspase 3, and reduced cytochrome C (Cyto C) release. Exposure to glutamate strongly inhibited phosphorylation of AKT (protein kinase B) and extracellular signal-regulated kinases (ERKs); however, GA pretreatment enhanced activation of ERKs but not AKT. The presence of PD98059 (a mitogen-activated protein/extracellular signal-regulated kinase kinase [MEK] inhibitor) but not LY294002 (a phosphoinositide 3-kinase [PI3K] inhibitor) diminished the potency of GA for improving viability of glutamate-exposed DPC12 cells. These results indicated that ERKs and mitochondria-related pathways are essential for the neuroprotective effect of GA against glutamate-induced toxicity in DPC12 cells. The present study provides experimental evidence supporting GA as a potential therapeutic agent for use in the treatment of neurodegenerative diseases.

Abstract
Amyloid deposits consist of protein fibrils and amorphous material, and this deposition is related to oxidative stress. Previously, we demonstrated the presence of high-density lipoproteins and/or lipids in amyloid deposits of familial amyloid polyneuropathy patients. In this study, the presence of myeloperoxidase (MPO) in amyloid deposits was demonstrated using immunohistochemical staining. In contrast, normal surrounding tissues were consistently negative for MPO. Nitrotyrosine was present in amyloid deposits after being exposed to the MPO/H2O2/NO(-) system by immunohistochemical staining, and the oxide mediated modification of serum transthyretin (TTR) was observed upon exposure to the MPO/H2O2 system using two-dimensional gel electrophoresis and TTR Western blotting. This observation revealed that the TTR amyloid deposits and serum TTR were oxidized by the MPO/H2O2/NO(-) system. Nitric oxide-mediated modification of TTR may play a role in amyloidogenesis in vivo.

Abstract
Pancreaticobiliary maljunction (PBM) is a type of congenital anomaly present in pancreatic duct development. Surgery is a reliable treatment for acute pancreatitis and biliary calculi induced by PBM, and can reduce the risk of carcinoma from congenital biliary dilatation. However, there have been few reports on postoperative complications. Here we report a case of recurrent gallstones in residual bile ducts after surgery for PBM. A review of the literature was also performed.

Abstract
A study of 7,388 consecutive patients after hepatic resection between 2011 and 2012 identified hepatolithiasis, cirrhosis, and intraoperative blood transfusion as the only independent risk factors of both incisional and organ/space surgical site infection (SSI). Patients with these conditions should be cared for with caution to lower SSI rates.

Abstract
BACKGROUND Improvements in surgical technique and perioperative care have made partial hepatectomy a safe and effective treatment for hepatocellular carcinoma (HCC), even in the event of spontaneous HCC rupture. METHODS A consecutive cohort of patients who underwent partial hepatectomy for HCC between 2000 and 2009 was divided into a ruptured group and a non-ruptured group. Patients with ruptured HCC were further divided into emergency and staged hepatectomy subgroups. Mortality and morbidity, overall survival and recurrence-free survival (RFS) were compared. Prognostic factors for overall survival and RFS were identified by univariable and multivariable analyses. RESULTS A total of 1233 patients underwent partial hepatectomy for HCC, of whom 143 had a ruptured tumour. The morbidity and mortality rates were similar in the ruptured and non-ruptured groups, as well as in the emergency and staged subgroups. In univariable analyses, overall survival and RFS were lower in the ruptured group than in the non-ruptured group (both P < 0·001), and also in the emergency subgroup compared with the staged subgroup (P = 0·016 and P = 0·025 respectively). In multivariable analysis, spontaneous rupture independently predicted poor overall survival after hepatectomy (hazard ratio 1·54, 95 per cent confidence interval 1·24 to 1·93) and RFS (HR 1·75, 1·39 to 2·22). Overall survival and RFS after hepatectomy for ruptured HCC in the emergency and staged subgroups were not significantly different in multivariable analyses. CONCLUSION Spontaneous rupture predicted poor long-term survival after hepatectomy for HCC, but surgical treatment seems possible, safe and appropriate in selected patients.

Abstract
Conjunctival inclusion cysts are the most common cystic lesions of the conjunctiva and are either congenital or acquired; the latter are more prevalent. Some of the major factors that provoke the development of an acquired cyst are surgery, trauma, and chronic inflammation. Here, we report on a conjunctival inclusion cyst that developed following a case of untreated chronic conjunctivitis. To temporarily relieve the patient's symptoms a needle aspiration of the cyst was performed, and the patient was referred to an ophthalmologist for surgical excision of the cyst.

Abstract
PURPOSE The BCLC staging classification has been widely endorsed to predict the prognosis of patients with HCC. However, its validity as a means of therapeutic instructions needs to be challenged. This study aimed to evaluate perioperative and long-term outcomes of surgical resection in patients with advanced hepatocellular carcinoma (HCC) according to the Barcelona Clinic Liver Cancer (BCLC) staging. METHODS This study used a prospectively maintained database consisting of a consecutive series of 511 Chinese patients with advanced HCC who underwent surgical resection in a hepatobiliary surgical center from 2001 to 2007. Mortality, morbidity, long-term overall survival (OS) and disease-free survival (DFS) were evaluated. RESULTS Hospital mortality was 2.3%, and overall morbidity was 31.3%. After a median follow-up period of 27.8 months (range, 0-112 months), the 1-, 3- and 5-year OS rate was 69.9, 41.2 and 30.5%, and the 1-, 3- and 5-year DFS rate was 48.2, 30.3 and 24.0%, respectively. The 1-, 3- and 5-year OS and DFS rates were significantly poorer in patients with vascular invasion and/or extrahepatic spread than those in patients without (both P < 0.001), and also poorer in patients with biliary invasion than those in patients without (both P < 0.05). CONCLUSIONS Surgical resection could be considered in part of patients with advanced HCC (BCLC stage C), with low mortality, acceptable morbidity and favorable survival benefits. These results imply that BCLC recommendations for treatment schedules of advanced HCC need to be re-evaluated.

Abstract
Krüppel-like factor 8 (KLF8) plays important role in cell cycle and oncogenic transformation. Here we report the mechanisms by which KLF8 crosstalks with Wnt/β-catenin signaling pathway and regulates hepatocellular carcinoma (HCC) cells proliferation. We show that overexpression of KLF8 and nucleus accumulation of β-catenin in the human HCC samples are positively correlated. More importantly, KLF8 protein levels plus nucleus accumulation of β-catenin levels were significantly elevated in high-grade HCC compared to low-grade HCC. Using HCC HepG2 cells we find that, on the one hand both protein and mRNA of KLF8 are up-regulated under Wnt3a stimulation, on the other hand overexpression of KLF8 increases the cytoplasm and nucleus accumulation of β-catenin, recruits p300 to β-catenin/T-cell factor 4 (TCF4) transcription complex, enhances TOP flash report gene transcription, and induces Wnt/β-catenin signaling target genes c-Myc, cyclin D1 and Axin1 expression. Knockdown of KLF8 using shRNA inhibits Wnt3a induced transcription of TOP flash report gene and expression of c-Myc, cyclin D1 and Axin1. Knockdown of β-catenin by shRNA rescues the enhanced HepG2 and Hep3B cells proliferation ability induced by overexpression of KLF8.

Abstract
Arsenic is highly toxic to living cells, especially skin, and skin cancer is induced by drinking water containing arsenic. The molecular mechanisms of arsenic-induced cancer, however, are not well understood. To examine the initial processes in the development of arsenic-induced cancer, we analyzed calcium signaling at an early stage of arsenic treatment of human primary cells and compared the effects with those observed with arsenic treatment in carcinoma-derived cells. We found that arsenic inhibited inositol trisphosphate receptor (IP3R) function in the endoplasmic reticulum by inducing phosphorylation, which led to decreased intracellular calcium levels. Blockade of IP3R phosphorylation by the serine/threonine protein kinase Akt inhibitor wortmannin rescued calcium signaling. In contrast, arsenic treatment of cells derived from a carcinoma (human squamous carcinoma; HSC-1) for 1h had no obvious effect. Taken together, these results suggest that arsenic-induced reduction in calcium signaling is one of the initial mechanisms underlying the malignant transformation in the development of skin cancer.

Abstract
AIM: To investigate the clinical features and prognostic factors of advanced hepatocellular carcinoma (HCC) patients presenting with lung metastasis at initial diagnosis.
METHODS: Between 2001 and 2010, we recruited 76 consecutive HCC patients initially presenting with lung metastasis, without co-existing metastasis from other sites. These patients were divided into three groups: untreated group (n = 22), single treatment group (n = 19), and combined treatment group (n = 35).
RESULTS: Metastasis of bilateral lung lobes was common and noted in 35 patients (46.1%), and most of patients (59/76, 77.6%) presented with multiple lung metastatic nodules. Nineteen patients (25.0%) received single-method treatment, including hepatectomy in 4, transcatheter arterial chemoembolization in 6, radiotherapy in 5, and oral sorafenib in 4. Thirty-five patients (46.1%) received combined treatment modalities. The overall median survival of the all patients was 8.7 ± 0.6 mo; 4.1 ± 0.3, 6.3 ± 2.5 and 18.6 ± 3.9 mo, respectively in the untreated group, single treatment group and combined treatment group, respectively, with a significant difference (log-rank test, P < 0.001). Multivariate analysis revealed that Child-Pugh score, the absence or presence of portal vein tumor thrombus, and treatment modality were three independent prognostic factors affecting survival of patients with advanced HCC and concomitant lung metastasis.
CONCLUSION: Combined treatment modalities tend to result in a better survival as compared with the conservative treatment or single treatment modality for HCC patients initially presenting with lung metastasis.

Abstract
Background & Aims: The aim of this prospective cohort study was to investigate the impact of preoperative hepatitis B viral load, as well as postoperative antiviral therapy, on the risk of long-term survival after curative resection of hepatitis B virus-related hepatocellular carcinoma (HCC). Methods A prospective cohort of hepatitis B virus-related HCC patients undergoing curative resection from 2001 to 2007 was studied. According to preoperative viral load (using 10,000 copies/mL of hepatitis B virus DNA level as cut-off value), two groups were compared. Prognostic factors for overall survival and recurrence-free survival were evaluated. Additionally, subgroup analysis was conducted in patients with high viral load to investigate prediction of postoperative antiviral therapy on the long-term prognosis. Results With a median follow-up of 49.1 months, patients with high viral load had lower median overall survival (78.3 months vs. 111.4 months, P < 0.001) and RFS (44.6 months vs. 94.8 months, P < 0.001) compared with those with low viral load. Multivariate analysis revealed that preoperative high viral load was an independent risk factor affecting both overall survival and recurrence-free survival (both P < 0.001). The subgroup analysis revealed that postoperative antiviral therapy independently improved recurrence-free survival for patients with high viral load (P = 0.001). Conclusions Hepatitis B virus-related HCC patients with preoperative high viral load led to poorer overall and recurrence-free survival than those with low viral load after curative resection. To prevent postoperative recurrence, antiviral therapy should be initiated in those patients with hepatitis B virus DNA ≤ 10,000 copies/ml.

Abstract
AIM Minimally invasive video-assisted thyroidectomy (MIVAT) and endoscopic thyroidectomy through areola (ETA) access are among the endoscopic approaches for thyroidectomy that have been perfected, but reports comparing the two are lacking. This study evaluated the safety, postoperative recovery, and patient satisfaction of MIVAT compared with ETA. METHODS This study included 119 patients undergoing MIVAT and 42 patients undergoing ETA from January 2006 to October 2009. Operative time, complications, postoperative recovery, cosmetic result, and patient satisfaction were analyzed. RESULTS The ETA group had a higher percentage of women (100% vs. 78.2%, P<0.05) and was younger (33.5 vs. 39 years, P<0.05). Thyroid volume (24.5 vs. 14.5 mL, P<0.001) and nodular diameter (26 vs. 22 mm, P<0.05) were larger in ETA group. The MIVAT group had a shorter operative time (28.2 vs. 112.8 minutes) and a lower rate of intraoperative (7.2 vs. 21.2 mL) and postoperative (0 vs. 80 mL, P<0.0001) blood loss. Rates of conversion and complications were similar. Postoperative pain at 12 hours was 1.9 in MIVAT vs. 3.1 in ETA (P<0.0001). Hospitalization was 1 day in the MIVAT group vs. 3.5 days in ETA (P<0.0001). Patient satisfaction was similar. CONCLUSION MIVAT and ETA showed similar results for safety, although ETA might be considered more invasive than MIVAT. Patients of both groups were equally satisfied with the cosmetic result. Differently from ETA, MIVAT allows total thyroidectomy to be performed also for malignant diseases. Although different, the two approaches were safe and reliable and both are valid options. Choice might depend on the surgeon's preference, thyroid size, type of disease, and the patient's expectation about cosmesis.

Abstract
BACKGROUND Major hepatic resection of more than three segments in patients with hepatocellular carcinoma (HCC) is a high-risk operation, especially in patients with co-existing underlying liver diseases. The present study evaluated risk factors for postoperative morbidity and mortality after major hepatic resection in HCC patients with underlying liver diseases. METHODS Perioperative data of 305 HCC patients with underlying liver diseases who underwent major hepatic resection were evaluated by univariate and multivariate analyses to identify risk factors for postoperative morbidity and mortality. RESULTS The overall morbidity rate was 37.0% (n = 113), caused by pleural effusion (n = 56), ascites (n = 43), subphrenic effusion/infection (n = 23), hepatic dysfunction (n = 22), bile leakage (n = 10), respiratory infection (n = 7), incision infection (n = 7), intra-abdominal hemorrhage (n = 5), and others. The hospital mortality rate was 2.6% (n = 8), primarily caused by liver failure (4/8). Multivariate logistic regression analysis showed that preoperative platelet count <100 × 10(9)/l (P = 0.006), and increased intraoperative blood loss (≥ 800 ml) (P = 0.008) were independent risk factors of postoperative morbidity, and that preoperative prothrombin time >14 s (P = 0.015) and preoperative platelet count <100 × 10(9)/l (P = 0.007) were independent risk factors for significant hospital mortality. CONCLUSIONS Careful preoperative selection of patients in terms of the Child-Pugh classification and decrease of intraoperative blood loss are important measures to reduce postoperative morbidity after major hepatic resection in HCC patients with underlying liver diseases. Moreover, we should be aware that preoperative platelet count is independently associated with postoperative morbidity and mortality for those patients following major hepatic resection.

Abstract
The Qidong cancer registry was established in 1972, and registration of cases is done by active and passive methods. The registry contributed data on 33 cancer sites or types registered during 1992-2000 for this survival study. Data on 22 cancers registered during 1972-2000 were utilized to elicit the survival trend by period and cohort approaches. Follow-up was done by a mixture of active and passive methods, with median follow-up ranging from 2-25 months. The proportion of cases with histologically verified cancer diagnosis ranged from 9-100%, and 87-100% of total registered cases were included for survival analysis. The top-ranking cancers on 5-year age-standardized relative survival (%) were thyroid (78%), breast (58%), corpus uteri (54%), larynx (51%) and urinary bladder (42%). The corresponding survival rates for common cancers were liver (6%), lung (7%) and stomach (18%). The 5-year relative survival by age group fluctuated and showed no distinct pattern or trend. The comparison of 5-year relative survival trend by cohort and period approaches revealed that period survival closely predicted the survival experience of cancer cases diagnosed in that period for most cancers.

Abstract
PURPOSE Surgical resection remains the gold standard for hepatocellular carcinoma (HCC). Although various staging systems have been developed in recent years, the best tool for staging of HCC remains controversial. The aims of this study were to establish a new staging for patients with HCC undergoing surgical resection and to identify whether this staging is superior to other staging systems in predicting survival of resectable HCC. METHODS The subjects of this retrospective study were 958 consecutive HCC patients who underwent surgical resection between 2000 and 2006. Predictors of survival were identified using the Kaplan-Meier method and the Cox model. The disease state was staged by our proposed Eastern staging system by integrating independent risk predictors, as well as six existing staging systems. The accuracy of prediction of 1-, 3-, and 5-year mortality for each system was evaluated by the area under the receiver operating characteristic curve (AUC). RESULTS Macroscopic vascular invasion, multiple tumors, performance status 1-2, microscopic vascular invasion, extrahepatic spread, tumor size > 5 cm, albumin < 35 g/L, aspartate aminotransferase > 40 U/L, total bilirubin > 17 μmol/L, and presence of cirrhosis were identified as independent risk factors of survival after resection by multivariate analysis. The comparison of the results of the different staging systems showed that our Eastern staging had the best homogeneity (likelihood ratio χ(2) test 543.51, P < 0.001), monotonicity of gradients (linear trend χ(2) test 414.97, P < 0.001), and discriminatory ability (the highest AUCs for 1-, 3-, and 5-year mortality). CONCLUSIONS Compared with other existing staging systems, our proposed Eastern staging system shows a superior predictive ability in a Chinese cohort of patients with resectable HCC, and it can give important prognostic information after surgery.

Abstract
OBJECTIVE This study aimed to evaluate the perioperative and long-term results of partial hepatectomy for patients with complicated bilateral primary hepatolithiasis. SUMMARY BACKGROUND DATA Hepatolithiasis is best managed by a multidisciplinary approach. Definitive treatment can be offered using endoscopic, percutaneous, laparoscopic, or open surgical approaches. Partial hepatectomy is only indicated for recurrent, troublesome, localized, and severe disease affecting the liver. METHODS From January 2000 to December 2006, 136 consecutive patients who underwent bilateral (n = 54) or unilateral (n = 82) hepatectomy for biliary strictures and bilateral primary hepatolithiasis in our center were included in this study. All patients had concomitant bile duct exploration. Their perioperative and long-term outcomes were analyzed. RESULTS The immediate stone clearance rates after bilateral and unilateral hepatectomy were 81.5% and 65.9%, respectively. Additional postoperative choledochoscopic lithotripsy raised the clearance rates to 85.2% and 81.7%, respectively. The hospital mortality rates were 5.6% and 0%, respectively, and the complication rates were 46.3% and 46.3%, respectively. The 5-year overall survival rates were 98% and 91.5%, respectively. CONCLUSION In selected patients with biliary strictures and bilateral hepatolithiasis, partial hepatectomy associated with choledochoscopic lithotripsy is a safe and efficacious treatment, with a high immediate stone clearance rate, a low long-term stone recurrence rate and good long-term survival.

Abstract
AIM: To evaluate outcomes in patients with autosomal dominant polycyst liver disease (APLD) treated by combined hepatic resection and fenestration. A new classification was recommended to presume postoperative complications and long outcome of patients.
METHODS: Twenty-one patients with APLD were treated by a combined hepatic resection and fenestration technique. All patients were reviewed retrospectively, and clinical symptoms, performance status and morbidity were recorded. A new classification of APLD is recommended here.
RESULTS: All patients were discharged when free of symptoms. The mean follow-up time was 55.7 mo and three patients had a recurrence of symptoms at 81, 68 and 43 mo after operation, respectively. The overall morbidity rate was 76.2%. Two patients with Type B-IIand Type B-I developed biliary leakage. Four patients had severe ascites, including three with Type B-III and one with Type B-II. Nine patients had pleural effusion, including one with Type A-I; one with Type B-I; five with Type B-II; one with Type A-III and one with Type B-III. Three patients with Type B had recurrence of symptoms, while none with Type A had severe complications.
CONCLUSION: Combined hepatic resection and fenestration is an acceptable procedure for treatment of APLD. According to our classification, postoperative complications and long outcome can be predicted before surgery.
