RESUMO
PURPOSE: Occult inguinal hernias (IH) predispose peritoneal dialysis (PD) patients to the symptomatic IH formation after starting PD, which may cause complications. We conducted a retrospective study to assess the benefit/risk profile of routine laparoscopic examination for occult IH (RLEOH) with a synchronous repair in patients receiving PD catheter placement. METHODS: 432 patients were enrolled in this study. Patients with an internal hernia sac at all sizes were deemed to have occult IH. We retrospectively reviewed data including demographic characteristics and operative details. We also measured incidence rates of symptomatic IH, metachronous IH repair, and catheter survival over a follow-up period after starting PD. RESULTS: These patients were classified into the RLEOH group (n = 365) and the non-RLEOH group (n = 67). The RLEOH group was subdivided into occult IH with a synchronous repair (n = 17; the subgroup A), no occult IH (n = 339; the subgroup B), and occult IH without a synchronous repair (n = 9; the subgroup C). The incidence rates of symptomatic IH developed after staring PD in subgroups A, B, and C were 0, 5.6, and 22.2%, respectively, whereas that in the non-RLEOH group was 13.4%. The RLEOH group had a reduced hazard ratio for metachronous IH repair compared with the non-RLEOH group (HR = 0.426; 95% CI 0.195-0.930, p = 0.032). None of our patients suffered from herniorrhaphy-related complications. CONCLUSION: RLEOH with a synchronous repair during PD catheter insertion confers clinical benefits in reducing the risk of developing IH after starting PD and the need for a metachronous repair. This is a safe and reasonable approach.

PURPOSE: Although many reports advocate computed tomography (CT) as the initial surveillance tool for occult cervical spine injury (CSI) at the emergency department (ED), the role of a lateral cervical spine radiograph (LCSX) has still not been replaced. We hypothesized that the increased width of the prevertebral soft tissue on an LCSX provides helpful information for selecting the high-risk patients who need to be evaluated with more accurate diagnostic tools. METHODS: This was a retrospective and consecutive series of injured patients requiring cervical spine evaluation who were first imaged with three-view plain films at the ED. The prevertebral soft tissue thickness (PVST) and ratio of prevertebral soft tissue thickness to the cervical vertebrae diameter (PVST ratio) were calculated on the LCSX. Suspicion of CSI was confirmed by either CT or magnetic resonance imaging (MRI) scans. RESULTS: A total of 826 adult trauma patients requiring cervical spine evaluation were enrolled. The C3 PVST and PVST ratio were significantly different between patients with or without upper cervical area injury (UCAI, 8.64 vs. 5.49 mm, and 0.394 vs. 0.276, respectively), and, likewise, the C6 PVST and PVST ratio for patients with or without lower cervical area injury (LCAI, 16.89 vs. 14.66 mm, and 0.784 vs. 0.749, respectively). The specificity was greater than 90 % in predicting UCAI and LCAI when combining these two parameters. CONCLUSIONS: This method maximizes the usefulness of LCSX during the initial assessment of a conscious patient with blunt head and neck injury, especially for the identification of high-risk patients requiring prompt CT or MRI; on the other hand, it prevents the overuse of these high-cost imaging studies as initial diagnostic tools.
RESUMO
Bile duct cells and hepatocytes differentiate from the same hepatic progenitor cells. To investigate the possible association of viral hepatitis B and C with intrahepatic cholangiocarcinoma (ICC), we conducted a retrospective case-control study using univariate and multivariate logistic analyses to identify risk factors for ICC. Besides hepatic lithiasis (25.6%; P<0.001), seropositivity for hepatitis B surface antigen (37.5% of all ICC patients; odds ratio (OR) =4.985, P<0.001) and seropositivity for hepatitis C antibodies (13.1%; OR=2.709; P=0.021) are the primary independent risk factors for ICC. Cirrhosis exerted synergic effects on the development of ICC. We compared the age distributions of viral-hepatitis associated ICC to that of viral hepatitis-associated hepatocellular carcinoma (HCC). The mean age of ICC patients with viral hepatitis B (56.4+/-11.1 years) were 9 years younger than that of ICC patients with viral hepatitis C (65.6+/-9.17 years), similar to that observed in HCC. The incidence ratio of HCC : ICC : CHC (combined hepatocellular cholangiocarcinoma) in our population was 233 : 17 : 1 consistent with the theoretic ratio of hepatocyte number to cholangiocyte number in the liver. Our findings indicated that both viral hepatitis-associated ICC and HCC shared common disease process for carcinogenesis and, possibly, both arose from the hepatic progenitor cells.

To evaluate the effective dose frequency (once daily vs. twice daily) of intrapleural urokinase treatment in children who required tube thoracostomy for drainage of a complicated parapneumonic effusion, we designed a randomised prospective study in a tertiary medical centre in Taiwan. From June 2002 to January 2005, 30 paediatric patients with complicated parapneumonic effusion who had received chest tube drainage were randomised 1 : 1 to the once-daily (urokinase 5000-6000 IU/kg/dose) or twice-daily (urokinase 2500-3000 IU/kg/dose) treatment. We compared clinical manifestations and outcomes in both groups. There were no differences in pleural effusion characteristics between the groups. Six patients had Streptococcus pneumoniae, one had Staphylococcus aureus, one had Group A Streptococcus, and 22 had unknown pathogens. There were no significant differences between the once- vs. twice-daily group in the amount of drained pleural fluid (564.9 +/- 422.1 ml vs. 560.5 +/- 198.6 ml, respectively), fever duration after chest tube insertion (4.3 +/- 3.2 days vs. 5.3 +/- 2.7 days), or total admission days (14.3 +/- 3.9 days vs. 14.6 +/- 3.0 days) (p > 0.05 for all). Only two patients (one in each group) required the surgery. Thus, we found that both once- and twice-daily administration of urokinase were similarly efficacious, and resulted in good clinical outcomes. Both obviated the need for surgery in most (93%) cases of pneumonia with complicated parapneumonic effusion in this series. A larger, multicentre study is necessary to verify our findings.

BACKGROUND: Since 1987, laparoscopic cholecystectomy (LC) has been widely used as the favored treatment for gallbladder lesions throughout the world. Because hemorrhage, infection, and delayed wound healing are the main causes of death after surgery for end-stage renal disease (ESRD), laparoscopic surgery is risky for ESRD patients. However, no information has been reported on such patients, so this study aimed to assess the safety of LC in ESRD patients. METHOD: From January 1994 to December 2003, the medical records of 58 ESRD patients under regular hemodialysis (HD) with gallbladder lesions undergoing LC were reviewed (ESRD-LC). The clinical features and outcomes of 6,182 patients with gallbladder lesions without ESRD undergoing LC were also summarized for comparison. RESULTS: Of 6,240 patients with gallbladder lesions undergoing LC, 58 (0.93%) had ESRD with regular HD. The ESRD-LC group clearly exhibited older age, higher frequency of associated disease, lower hemoglobin and platelet count, and elevated alkaline phosphatase, blood urea nitrogen, and creatinine values. However, only a higher frequency of high American Society of Anesthesiologists (ASA) grade and elevated creatinine value could differentiate ESRD-LC and LC patients by multivariate analysis. Similar blood loss, conversion rate, morbidity, mortality, and hospital stay were noted for the two groups. CONCLUSIONS: LC is safe for ESRD patients with gallbladder lesions. Only a higher frequency of high ASA grade and elevated creatinine value could differentiate ESRD-LC and LC patients. Similar blood loss, conversion rate, morbidity, mortality, and hospital stay were achieved by applying LC to treat ESRD patients. However, appropriate preoperative preparations and experienced operative techniques are still required to prevent mortality.

BACKGROUND: Mirizzi syndrome is an uncommon complication of longstanding gallstone disease resulting in obstructive jaundice and remains surgically challenging. Mirizzi syndrome is generally considered a contraindication to laparoscopic surgery. We present the surgical experience of 11 consecutive patients with Mirizzi syndrome who were diagnosed correctly preoperatively and treated laparoscopically. METHODS: From January 1991 to December 2001, 4,560 patients underwent laparoscopic cholecystectomy for gallbladder lesions, 11 (0.24%) of whom were diagnosed with Mirizzi syndrome. RESULTS: The 11 patients diagnosed with Mirizzi syndrome included four men and seven women, with ages ranging from 21 to 72 years (median, 54). There were 10 patients with Mirizzi syndrome type I (one was caused by gallbladder cancer in the neck), and 1 patient with type II, according to McSherry's classification. Right upper quadrant abdominal pain was the most common symptom, occurring in all 11 patients. All 11 patients were diagnosed correctly preoperatively by endoscopic retrograde cholangiography (ERCP) with 100% sensitivity. Four of the 11 patients (36.4%) were converted to open procedure. The postoperative course was uneventful, except for one patient complicated with a residual common bile duct stone. Hospital stay ranged from 4 to 33 days (median, 7). CONCLUSIONS: Mirizzi syndrome is an uncommon disorder. Preoperative suspicion is crucial for correct preoperative diagnosis. ERCP is the most useful tool for correct preoperative diagnosis and consequent prevention of common bile duct injury during operation. Should Mirizzi syndrome be diagnosed, laparoscopic treatment is a feasible and safe procedure, especially for type I Mirizzi syndrome.

AIMS: We examined the clinical features and outcome of 80 patients with hepatocellular carcinoma (HCC) who had undergone hepatic resection; 32 patients were under 30 years old (younger-HCC), and 48 patients were over 70 years (elderly-HCC). METHODS: Clinical features of 32 cases of younger-HCC (less than 30 years old) and 48 elderly-HCC (over 70 years old) were reviewed between 1986 and 1999. The clinical features, pathological findings and outcome of the younger and elderly HCC patients were summarized for comparison. RESULTS: Of 573 HCC patients who underwent hepatic resection, 32 were younger than 30 years old and 48 older than 70 years. Less hepatitis B infection, higher hepatitis C infection, more liver cirrhosis development, and a higher ICG 15min retention ratio than the younger group. The younger group tended to have a larger tumor size, more major hepatectomy, more operative blood loss during operation, more perioperative blood transfusion, and more recurrence when compared with the elderly-HCC group. The elderly-HCC group had a significantly better disease-free survival rate than the younger-HCC group. The younger-HCC group had a similar overall survival rate to the elderly-HCC group. CONCLUSIONS: These results seem to indicate a possible difference in the HCC carcinogenesis between younger and elderly patients. The overall survival of the younger HCC patients who undergone hepatic resection was as favorable as that of the elderly.

BACKGROUND: Hepatocellular carcinoma (HCC) is a common disease in Taiwan. Ruptured HCC is an uncommon and potentially fatal complication of the condition. Information on the impact of ruptured HCC on hepatic resection is, however, limited. METHODS: The clinical features of 60 patients with ruptured HCC who underwent hepatic resection from 1986 to 1998 were reviewed. Clinical features and factors influencing the outcome of 475 patients with non-ruptured HCC were used for comparison. RESULTS: Of 535 surgically resected HCCs, 60 (11.2 per cent) were ruptured. Univariate analysis showed that sudden onset of abdominal pain, physical signs of haemodynamic unstability, reduced haemoglobin level and a raised aspartate aminotransferase level were more frequently found in patients with ruptured HCC than in those with non-ruptured tumours. Multivariate stepwise logistic regression analysis revealed sudden-onset abdominal pain to be the only independently significant factor in patients in the ruptured HCC group. The 1-, 3- and 5-year survival rates of patients with non-ruptured HCC were 72.1, 47.3 and 33.9 per cent, and those of patients with ruptured HCC were 54.2, 35.0 and 21.2 per cent respectively. Similar overall survival rates were found in patients with ruptured and non-ruptured HCC, although patients in the non-ruptured HCC group had a significantly better disease-free survival rate (P = 0.023). CONCLUSION: The presence of sudden-onset abdominal pain is the only independent indicator of ruptured HCC. Hepatic resection, when feasible, is the treatment of choice and can result in an overall survival rate comparable to that of patients with non-ruptured HCC.

BACKGROUND: Since 1987, laparoscopic cholecystectomy (LC) has been widely used as the favored treatment for gallbladder lesions. However, cirrhosis and portal hypertension have been considered relative or absolute contraindications to LC. This study aimed to assess the safety of LC in cirrhotic patients. METHOD: The medical records of 226 cirrhotic patients with gallbladder lesions who had undergone LC from 1991 to 2000 were reviewed, including demographics, severity of cirrhosis, laboratory data, operative morbidity, operative mortality, and hospital stay. Furthermore, the clinical features and outcomes of 4030 patients with gallbladder lesions without cirrhosis that had undergone LC were also summarized for comparison. RESULTS: Of 4256 patients with gallbladder lesions that had undergone LC, 226 (5.6%) had cirrhotic livers. The cirrhotic group patients clearly exhibited the trends of older age, worse liver function, higher blood loss, and higher mortality compared to the noncirrhotic group patients. CONCLUSIONS: This study presents the clinical features and outcomes of 226 cirrhotic patients who underwent LC. LC, once considered contraindicated in patients with cirrhosis, is a feasible procedure for most Child's A and B patients with cholecystolithiasis. Minor morbidity, an acceptable conversion rate, and shorter hospital stay can be achieved by applying LC to treat cirrhotic patients. However, appropriate preoperative preparations and meticulous operative techniques are required to reduce blood loss during laparoscopy and even mortality.

BACKGROUND AND OBJECTIVES: Angiomyolipoma is a rare benign tumor that occurs in the liver and other organs. We provide data on eight cases of hepatic angiomyolipoma, regarding clinical presentations, diagnoses, management, and prognosis. METHODS: A retrospective review of medical records of the eight patients with hepatic angiomyolipoma treated at the Chang Gung Memorial Hospital-Taipei between October 1988 and October 1999. RESULTS: Eight female patients with hepatic angiomyolipoma were identified, with ages ranging from 30 to 66 years (mean, 45.3 years). Abdominal pain was the most common symptom, occurring in six of eight patients (75%). Hepatocellular carcinoma was the most common preoperative diagnosis, occurring in three of eight patients (37.5%). Laparotomy was performed in seven of eight patients (87.5%). Among these seven patients, three patients (43%) received hepatic resection with 100% cure rate to date. One of the eight patients (12.5%) was closely follow up after diagnosis made by echo-guided needle biopsy. CONCLUSIONS: Hepatic angiomyolipoma is a rare and benign entity. It has a wide variation and poses a diagnostic challenge clinically, radiologically, and pathologically. Its prognosis is good regardless of management, including hepatic resection or conservative treatment after tissue biopsy by echo-guided needle. To alleviate the mass effect, surgical resection may be needed for hepatic angiomyolipoma in selected cases.

The size and number of gallbladder polyps are used to differentiate between benign and malignant lesions before surgery and to determine whether surgery is necessary for the lesion. Since 1987, laparoscopic cholecystectomy has been widely used as the management method of choice for gallbladder lesions. The results of a clinicopathologic study of polypoid lesions of the gallbladder, based completely on laparoscopically resected gallbladder tissue, have not yet been evaluated fully. Data from 123 patients with polypoid lesions of the gallbladder treated by laparoscopic cholecystectomy were reviewed retrospectively. The gallbladders were classified into four histologic groups. Clinical features, maximal diameter, and the number of lesions were compared among the groups. The mean age of patients with adenoma and cancer was significantly greater than that of patients with cholesterol polyps and other lesions. More women than men had a neoplasm (adenoma and cancer). Patients in the neoplasm group tended to have a single lesion. The mean maximal diameter of neoplasms was significantly larger than that of lesions in the nonneoplasm group. All seven malignant lesions that were detected measured at least 1.5 cm. Univariate analysis showed that polypoid lesions of the gallbladder with neoplastic lesions correlated significantly with age, sex, size, and number of the lesions. Univariate analysis also showed that malignancy in polypoid lesions of the gallbladder correlated significantly with age, size, and number of the lesions. Multivariate logistic regression analysis showed that the age of the patient and the size of the lesion (> or = 1.0 cm) are two independent factors in predicting neoplastic lesions in polypoid lesions of the gallbladder. The size of the lesion (> or = 1.5 cm) is the only independent factor in predicting malignancy in the polypoid lesions of the gallbladder as shown by multivariate logistic regression analysis. Laparoscopic cholecystectomy is a safe and feasible method for gallbladder polypoid lesions. Neoplastic change in polypoid lesions of the gallbladder should be considered when a patient older than 50 years of age has a polypoid lesion larger than 1.0 cm. Cancer should be suspected when a polypoid lesion of the gallbladder is larger than 1.5 cm, and an aggressive surgical approach is warranted so that early gallbladder cancer can be detected and patients can have an increased chance of cure.

A 42-year-old man with dermatomyositis presented with right-upper-quadrant dull pain and normal blood pressure for 10 days. Abdominal ultrasonography, abdominal computed tomography, and angiography revealed a retroperitoneal tumor with direct invasion to the liver and the diaphragm. The diagnosis of nonfunctioning malignant pheochromocytoma was made on the basis of clinical evidence. The tumor was removed en bloc with part of the diaphragm, the right lobe of the liver, the right adrenal gland, and the right kidney. Pathologic examination with immunohistochemical staining revealed a malignant pheochromocytoma growing exophytically from the right adrenal gland and invading the right lobe of the liver and the diaphragm. The postoperative course has been uneventful and no recurrence has been noted over a 6-month follow-up period.

A 68-year-old woman presented with secretory watery diarrhea causing hypokalimia, hypoalbuminemia and dehydration for 5 years. Subsequent investigations including abdominal ultrasonography and computed tomography scanning revealed a mass measuring 7 x 6 cm in the pancreatic tail. The diagnosis of pancreatic VIPomas was suspected on the basis of clinical symptoms. The patient underwent distal pancreatectomy and splenectomy after resuscitation of electrolyte imbalance, dehydration and malnutrition. The pathological examination with histoimmunochemical stain confirmed the diagnosis. Postoperative course is uneventful and the patient does not have symptoms any longer during the follow-up period.

In this study we present a rare case of cholangiocarcinoma with metastasis to the thoracic spine. A 63-year-old female with peripheral cholangiocarcinoma associated with hepatolithiasis presented low back pain as a result of a thoracic spine (T12) compression fracture. Spine surgery and pathological examination revealed a metastatic mucinous adenocarcinoma of unknown origin. Two weeks after the spine surgery, a nontender palpable abdominal mass was found at the epigastric area. Abdominal sonography (US), abdominal computed tomography (CT), and magnetic resonance cholangiopancreaticogram (MRCP) revealed a hepatic tumor, hepatolithiasis, and gallbladder empyema. The patient underwent hepatic resection, cholecystectomy, and choledocholithotomy with T-tube stent. Pathological examination with immunohistochemical stain revealed hepatolithiasis concurrent with mucinous cholangiocarcinoma. Postoperative course was uneventful and no recurrence was noted during a 1-year follow-up period.
