RESUMO
BACKGROUND: Iatrogenic hepatic artery pseudoaneurysm is a rare complication following laparoscopic cholecystectomy. Trans-arterial embolization (TAE) is an effective way to control bleeding after a ruptured aneurysm. But uncommonly, rebleeding may occur which will require a second embolization or even laparotomy. CASE PRESENTATION: We report a case of a 45-year-old woman who underwent robotic-assisted cholecystectomy after the diagnosis of type II Mirizzi syndrome. During the operation, the anterior branch of the right hepatic artery was damaged and Hem-o-lok clips were applied to control the bleeding. The postoperative course was smooth, and the patient was discharged 6 days after the procedure. However, one week after hospital discharge, she presented to the emergency department with right upper abdominal tenderness, melena, and jaundice. After examination, the computed tomography angiography (CTA) revealed a 3 cm pseudoaneurysm at the distal stump of the right hepatic artery anterior branch. TAE with gelfoam material was performed. Three days later, the patient had an acute onset of abdominal pain. A recurrent pseudoaneurysm was found at the same location. She underwent TAE again but this time with a steel coil. No further complication was noted, and she was discharged one week later. CONCLUSIONS: Even with the assistance of modern technologies such as the robotic surgery system, one should still take extra caution while handling the vessels. Also, embolization of the pseudoaneurysm with steel coils may be suitable for preventing recurrence.

BACKGROUND: This study investigates differences in depression and anxiety between patients with chronic hepatitis C who are treated with peginterferon alpha-2a (PegIFN-α-2a) plus ribavirin and those who are treated with peginterferon alpha-2b (PegIFN-α-2b) plus ribavirin. METHODS: In this 24 week, non-randomized, observational, prospective study, 55 patients with chronic hepatitis C were treated with PegIFN-α-2a plus ribavirin (Group 1), and 26 patients were treated with PegIFN-α-2b plus ribavirin (Group 2). All patients underwent assessment using the Hospital Anxiety and Depression Scale (HADS) at the baseline and at weeks 4, 12 and 24. Patients with depression scores (HADS-D) ≥ 8 and anxiety scores (HADS-A) ≥ 8 were defined as having depression and anxiety, respectively. The factors that were associated with depression and anxiety during the 24 week antiviral treatment were determined. RESULTS: During the 24 week antiviral treatment, the proportion of patients with depression significantly increased over time in both groups (Group 1: p = 0.048; Group 2: p = 0.044). The proportion of patients with anxiety did not significantly change during the follow-up period in either group. Incidences of depression or anxiety did not differ significantly between Group 1 and Group 2. A history of alcohol use disorder was an independent predictor of depression at week 12 (p < 0.001) and week 24 (p < 0.001), and a poor virological response to treatment was associated with depression at week 24 (p = 0.029). Patients who had more physical comorbidities were more likely to suffer from anxiety at week 12 (p = 0.038). CONCLUSIONS: This study did not identify significant differences in depression or anxiety between in patients with chronic hepatitis C who underwent a 24 week antiviral treatment regimen with PegIFN-α-2a plus ribavirin and those who underwent a regiment with PegIFN-α-2b plus ribavirin. Future research with larger samples and a randomized, controlled design are required to verify the findings in this study. TRIAL REGISTRATION: This clinical study has been registered at ClinicalTrials.gov. (Trial registration: NCT02943330 ).

OBJECTIVES: The purpose of our study was to evaluate the relationship between spleen stiffness measured by transient elastography and the degree of thrombocytopenia in patients with liver cirrhosis. METHODS: A total of 67 patients with liver cirrhosis were prospectively enrolled in the study. All patients underwent single-day hematologic and biochemical tests, sonography, and transient elastography of the liver and spleen. Thrombocytopenia was categorized as mild (platelet count, 75,000-150,000/µL), moderate (50,000-75,000/µL), and severe (<50,000/µL). RESULTS: The degree of thrombocytopenia was significantly correlated with spleen stiffness (P = .001) and spleen size (P = .002) but not with liver stiffness (P = .086). In patients without splenomegaly, spleen stiffness values were significantly higher in patients with thrombocytopenia than in those without thrombocytopenia (P = .035). In patients with splenomegaly, spleen stiffness values were significantly higher in patients with moderate to severe thrombocytopenia than in those with a normal platelet count or mild thrombocytopenia (P = .007). Compared to liver stiffness, spleen stiffness showed a better and statistically significant correlation with platelet count and spleen size in patients with cirrhosis. CONCLUSIONS: The degree of thrombocytopenia was directly correlated with spleen stiffness, irrespective of the presence of splenomegaly. The clinical phenomenon of unexpected thrombocytopenia may be explained by a subtle or irreversible change in spleen stiffness.

BACKGROUND AND AIM: CO2 has been reported to be absorbed from the bowel more rapidly than air, resulting in a discomfort reduction after colonoscopy. Its role in deeply sedated patients is limited. This study was designed to investigate the efficacy and safety of CO2 insufflation during colonoscopy in patients deeply sedated with propofol. METHODS: A total of 125 continuous patients were randomly assigned to receive either CO2 (n = 63) or air (n = 62) insufflation during propofol-sedated colonoscopy. Postcolonoscopy abdominal pain, distention, and satisfaction were assessed at 1, 3, and 24 h after the procedure, and the proportions of pain-free and distention-free patients were compared. Residual bowel gas in the colon and small bowel was evaluated at 1 h after colonoscopy. End-tidal CO2 and O2 saturation was measured for safety analysis. RESULTS: There was a significant difference between the two groups regarding the postcolonoscopy abdominal pain, distention, and subjective satisfaction at 1 h (P < 0.001) and 3 h (P < 0.01) after the procedure. Patients' pain and distention at 1 and 3 h after the procedure were significantly lower in the CO2 group (P < 0.01). Residual bowel gas in the colon and small bowel was significantly less in the CO2 group (P < 0.001). There was no significant difference in end-tidal CO2 levels between two groups before, during, and after the procedure. CONCLUSIONS: Compared with air, CO2 insufflation during colonoscopy reduced postcolonoscopy abdominal discomfort and improved patients' satisfaction. It was safe to use CO2 insufflation in deeply sedated colonoscopy.

Peliosis hepatis (PH) is a vascular lesion of the liver that mimics a hepatic tumor. PH is often associated with underlying conditions, such as chronic infection and tumor malignancies, or with the use of anabolic steroids, immunosuppressive drugs, and oral contraceptives. Most patients with PH are asymptomatic, but some present with abdominal distension and pain. In some cases, PH may induce intraperitoneal hemorrhage and portal hypertension. This study analyzed a 46-year-old male who received a transplanted kidney nine years prior and had undergone long-term immunosuppressive therapy following the renal transplantation. The patient experienced progressive abdominal distention and pain in the six months prior to this study. Initially, imaging studies revealed multiple liver tumor-like abnormalities, which were determined to be PH by pathological analysis. Because the hepatic lesions were progressively enlarged, the patient suffered from complications related to portal hypertension, such as intense ascites and esophageal varices bleeding. Although the patient was scheduled to undergo liver transplantation, he suffered hepatic failure and died prior to availability of a donor organ.

OBJECTIVE: We wanted to report on our experience with modified radiology-guided percutaneous gastrostomy (MRPG) without endoscopic or nasogastric access for treating patients with complete obstruction of the upper digestive tract. MATERIALS AND METHODS: Fourteen oncology patients (13 had hypopharyngeal cancer and 1 had upper esophageal cancer) with complete obstruction of the upper digestive tract were recruited. Conventional percutaneous endoscopic gastrostomy (PEG) and radiologic (fluoroscopy-guided) percutaneous gastrostomy (RPG) were not feasible in all the patients. An MRPG technique (with a combination of ultrasound, an air enema and fluoroscopic guidance) was performed in these patients. RESULTS: We achieved successfully percutaneous gastrostomy using the modified technique in all patients without any major or minor complications after the procedure. CONCLUSION: A modified radiology-guided percutaneous gastrostomy technique can be safely performed in patients who failed to receive conventional PEG or RPG due to the absence of nasogastric access in the completely obstructed upper digestive tract.

BACKGROUND: Endoscopic ultrasonography (EUS) has often been used to evaluate gastric subepithelial masses (SEM) and their malignant potential. Information on the use of EUS to survey small gastric SEM is limited. METHODS: A total of 125 consecutive patients referred for evaluation of a suspected gastric SEM were evaluated by EUS from February 2002 to February 2008. Periodic surveillance using EUS or upper gastrointestinal endoscopy was routinely advised. Surgical treatment was considered if a malignant tumor was suspected or symptomatic. RESULTS: In the 125 patients, EUS found 23 (18.4%) cases of extraluminal compression, 70 (56%) gastrointestinal stromal tumors (GISTs), 9 (7.2%) cases of ectopic pancreas, 5 (4.0%) mucosal tumors, 3 (2.4%) cases of varices, 2 (1.6%) cysts, 2 (1.6%) lipomas, 1 (0.8%) mucosal polyp, 1 (0.8%) submucosal tumor, 6 (4.8%) patients with no abnormality, and 3 (2.4%) unidentified lesions. Surgery was performed in 15 patients, revealing GISTs in 10 patients, and gastrointestinal autonomic nervous tumors (GANTs) in 2 patients as well as other malignant lesions in 3 patients. The pathological findings confirmed that 11 (73.3%) of 15 larger tumors (> 30 mm) were accurately diagnosed. Only 1 of 9 suspected GIST (mean initial tumor size 13.4 +/- 8.3 mm, mean follow-up period 23 months), in the EUS surveillance group significantly increased in size, and surgical pathology disclosed a GIST with intermediate malignant potential. CONCLUSIONS: For evaluating gastric SEM, EUS is able to accurately differentiate intramural from extramural lesions and aid in narrowing the differential diagnosis. In this limited case study, most small gastric SEM (< 30 mm) did not exhibit size changes during follow-up. If the tumor size increases or the ultrasonographic features of a tumor suggest malignant possibility during EUS surveillance, surgical resection should be considered.

Hepatitis C virus (HCV) and hepatitis B virus (HBV) share similar transmission routes, but concurrent acute HCV and HBV infection was rarely reported. Little is known about viral interaction and hepatic biochemical features of acute HBV and HCV coinfection. We report an intravenous drug abuser with simultaneous acute HBV and HCV infections presenting as biphasic elevation of both alanine aminotransferase (ALT) and total bilirubin levels. HCV infection is the major cause of continuing hepatitis after termination of HBsAg antigenemia.

BACKGROUND/AIMS: Although H. pyloric eradication therapy is indicated for peptic ulcer patients, the prevalence of H. pylori infection may be different between patients with active or chronic (scarred) peptic ulcers. This study aimed to compare the prevalence of H. pylori infection in active and chronic peptic ulcer patients with or without previous H. pyloric eradication therapy. METHODOLOGY: Both non-invasive (13C or 14C urea breath test) and invasive methods (rapid urease test and histology) were used to detect H. pylori. From Dec. 2002 to Jan. 2003, 153 patients with 63% male were enrolled in this study. Fifty-six patients who previously received H. pyloric eradication therapy were enrolled as treated patients, and 97 patients who did not receive therapy were enrolled as untreated patients. RESULTS: H. pylori infection rate was still high in untreated patients even when duodenal ulcer had been scarred (96% in active duodenal ulcer and 63% in scarred duodenal ulcer). In treated patients, H. pyloric infected rates were very low when peptic ulcers were scarred (0% in scarred gastric ulcer, 4% in scarred duodenal ulcer and 0% in both scarred ulcers). CONCLUSIONS: H. pyloric eradication therapy is indicated for untreated patients even when endoscopic examination revealed chronic scarred duodenal ulcer.

AIM: To assess the efficacy of ribavirin monotherapy in patients with biochemical relapse after combination therapy. METHODS: Twenty-four weeks of ribavirin monotherapy was given to biochemical relapsers of end treatment biochemical responders within 6 mo after combination therapy, including non-responders with HCV-RNA level < or =0.2 Meq/mL and end treatment virologic responders (ETVRs) with or without reappearance of HCV-RNA. RESULTS: Sixty-two chronic HCV-infected patients completed 24 wk of interferon-alpha plus ribavirin combination therapy. Fifty patients (80%) achieved end treatment biochemical response including 16 non-responders and 34 of 36 ETVRs. Twenty-six patients (41.9%) were non-responders. Ribavirin monotherapy was given to 20 biochemical relapsers including 12 non-responders with HCV-RNA levels < or =0.2 Meq/mL, four of eight HCV-RNA reappearing ETVRs, and four HCV-RNA negative ETVRs. After 24 wk of ribavirin monotherapy, one of 12 non-responders, two of four HCV-RNA reappearing ETVRs and all four RNA-negative biochemical relapsers of ETVRs showed sustained virologic response. Two of 12 monotherapy treated non-responders showed persistent normalization of liver function test. In total, 50% (31/62) of patients achieved sustained virologic response. CONCLUSION: Resumption of ribavirin monotherapy in ETVRs at signs of viral rebound and recurrent biochemical abnormalities rather than continuation of monotherapy appears to be the key to success of ribavirin monotherapy after interferon-related combination therapy.

Outpatient percutaneous liver biopsy is a common practice in the differential diagnosis and treatment of chronic liver disease. The major complication and mortality rate were about 2-4% and 0.01-0.33% respectively. Arterio-portal fistula as a complication of percutaneous liver biopsy was infrequently seen and normally asymptomatic. Hemobilia, which accounted for about 3% of overall major percutaneous liver biopsy complications, resulted rarely from arterio-portal fistula We report a hemobilia case of 68 years old woman who was admitted for abdominal pain after liver biopsy. The initial ultrasonography revealed a gallbladder polypoid tumor and common bile duct (CBD) dilatation. Blood clot was extracted as endoscopic retrograde cholangiopancreatography (ERCP) showed hemobilia. The patient was shortly readmitted because of recurrence of symptoms. A celiac angiography showed an intrahepatic arterio-portal fistula. After superselective embolization of the feeding artery, the patient was discharged uneventfully. Most cases of hemobilia caused by percutaneous liver biopsy resolved spontaneously. Selective angiography embolization or surgical intervention is reserved for patients who failed to respond to conservative treatment.
