Methods:Data on 11 robot-assisted laparoscopic partial nephrectomies performed by using our technique from February 2015 through June 2015 were retrospectively analyzed. The robotic platform used was DaVinci Xi (Intuitive Surgical, Inc., Sunnyvale, California, USA) with a 3-arm setup. The AirSeal system (SurgiQuest, Milford, Connecticut, USA) was used as a port allowing simultaneous introduction of 2 instruments for the bedside surgeon, obviating the need for an additional (fourth) robotic arm. A long suction-and-irrigation device and atraumatic grasping forceps were used. Both instruments were introduced through the trocar of the AirSeal system, making simultaneous introduction and use possible. We preferred the long suction-and-irrigation device, because it minimizes collision of the instruments.Results:Mean age and BMI of the patients were 55 ±14.6 y and 29.18 ± 6.85, respectively. Seven tumors were on the right side and 4 were on the left. The mean size of the tumors was 32.45 mm (± 11.31). Surgical time was 132.2 minutes (±37.17), with an estimated blood loss and ischemia time of 103.63 mL (±65.92) and 16.72 minutes (±9.52), respectively. One patient had postoperative bleeding that was resolved without transfusion. The median hospitalization period was 3.9 d (±0.53). Loss of intra-abdominal pressure was not observed, and pressure was stable at 10 mm Hg.Conclusion:The AirSeal System and its valveless trocar eliminated the need for an additional port placement in our series. The technique is feasible, safe, and reproducible; therefore, it may be implemented in selected cases of robot-assisted partial nephrectomies. 相似文献

Background: Although the risk and related factors of hyperkalemia developed in the hospital are known in elderly, risk and related factors of community-acquired hyperkalemia (CAH) in this population are not well known. This study was performed to investigate the risk of CAH in elderly and evaluate the related factors and clinical outcomes.Study design, setting and participants, intervention: Patients (aged ≥65 years) with hyperkalemia were screened. Group 1 (young-old); 65–74 years/old, Group 2 (middle-old); 75–84 years/old, Group 3 (oldest-old); ≥85 years/old, and Group 4 (control group); ≥65 years/old (normal serum potassium levels). The relation between CAH and hospital expenses (HE), the number of comorbid diseases (NCD), and all-cause of mortality rates (MR) were evaluated. We also investigated whether drugs, sex, and NCD are risk factors for the development of CAH.Results: There was a positive correlation between serum potassium levels and length of hospital stay, MR, HE, and NCD (p?<?0.001). Risk factors for CAH were the use of non-steroidal-anti inflammatory drugs (NSAIDs) (Odds Ratio [OR]: 2.679), spironolactone (OR: 2.530), and angiotensin converting enzyme inhibitors (ACEI) (OR: 2.242), angiotensin receptor blockers (ARB) (OR: 2.679), ≥2 comorbid diseases (OR: 2.221), female gender (OR: 2.112), and renal injury (OR: 5.55). CAH risk was found to be increased 30.03 times when any of ACEI, ARB, NSAIDs, or spironolactone is given to a patient with a renal injury.Conclusion: Use of NSAIDs, ACEI, ARB, spironolactone and increased NCD are all independent risk factors for CAH in the elderly, especially in patients with kidney diseases. 相似文献

ObjectivePancreatic renin-angiotensin system has been implied to play a role in the regulation of pancreatic functions and could be a new therapeutic target in acute pancreatitis. The aim of this study was to evaluate the therapeutic potential of angiotensin-converting-enzyme inhibition by captopril and angiotensin II type1 receptor inhibition by L-158809 and losartan experimentally in acute pancreatitis.DesignRats were randomly divided into 15 groups. Acute edematous pancreatitis was induced by injection of cerulein 20 μg/kg SC four times at hourly intervals. Severe necrotizing pancreatitis was induced by retrograde injection of 3% taurocholate into the biliary-pancreatic duct.InterventionsCaptopril, L-158809 and losartan were given intraperitoneally. Main outcome features: pancreatic pathology, pancreatic myeloperoxidase activity and serum amylase activity were assessed.ResultsCaptopril decreased serum amylase (10,809±1867 vs. 4085±1028 U/L, p<0.01), myeloperoxidase activity (3.5±0.5 vs. 1.5±0.1, p<0.05) and histopathological score (5.0±0.4 vs. 1.1±0.5, p<0.01) in acute edematous pancreatitis. In taurocholate induced severe necrotizing pancreatitis captopril ameliorated histopathological score (10.1±1.2 vs. 3.4±0.5, p<0.01), pancreatic parenchymal necrosis (4.5±0.6 vs. 0.0±0.0, p<0.001), fatty necrosis (2.8±0.9 vs. 0.1±0.1, p<0.01) and edema (2.1±0.3 vs. 1.4±0.3, p<0.05). However, L-158809 did not have similar beneficial effects on acute pancreatitis in rats while losartan decreased pancreatic parenchymal necrosis and neutrophil infiltration.ConclusionsThis study not only demonstrated the differential effects of captopril, losartan and L-158809 in acute pancreatitis but also showed that there is still much to investigate about pancreatic renin-angiotensin system. Inhibition of angiotensin-converting enzyme should be evaluated carefully as a potential new therapeutic target in acute pancreatitis. 相似文献

The only beneficial agent for the treatment of chronic delta hepatitis (CDH) is interferon (IFN). However, there is no consensus on the best dosage or duration of IFN therapy. As ribavirin (RBV) increases the sustained response when added to IFN in chronic hepatitis C, probably because of its immunomodulatory effect, we aimed to investigate the efficacy of 2-year IFN treatment and whether RBV had any additive effect to IFN in CDH. METHODS: Patients (n = 31) with CDH were randomized with a 1:2 ratio as 10 patients (3 females/7 males, age 39 +/- 9) receiving IFN monotherapy (9 MU IFN-alpha2a three times weekly) and 21 patients (8 females/13 males, age 38 +/- 11) receiving IFN plus RBV for 2 years (IFN at the same dosage and RBV at 1000-1200 mg/day). Alanine transferase normalization and hepatitis delta virus (HDV) RNA negativity at the end of treatment and at the end of the follow-up period (at least 6 months following 2-year treatment) were primary endpoints of the study. In addition, virological response and biochemical response were determined separately. RESULTS: Eight of 31 patients (25%) had cirrhosis in liver biopsies. Six patients from the IFN monotherapy group and 12 patients from the combination group had biochemical response. Five patients from the IFN monotherapy group and 11 patients from the combination group had virological response at the end of therapy. Two patients from the IFN group and five patients from the combination group had sustained biochemical response at the end of the follow-up period. Hepatitis B virus (HBV) activations with HBV DNA positivity were observed in two patients (one from the IFN monotherapy group, one from the combination group). Two patients (20%) in the IFN group and five patients (23.5%) in IFN plus RBV group remained as virological responders at the end of the follow-up period (P > 0.05). None of the patients with liver cirrhosis were responsive at the end of the follow-up period. CONCLUSION: Almost 20% of the patients with CDH were responsive to 2-year IFN treatment at the end of the follow-up period and no additional effect of RBV was observed. Patients with advanced liver disease failed to respond to treatment. 相似文献

Xanthogranulomatous salpingitis (XGS) is a rare form of chronic inflammation of the fallopian tubes. A 41-year old woman with a history of secondary infertility for 2 years is presented. The patient underwent bilateral salpingooopherectomy with presumptive diagnosis of adnexal mass with cystic component. Intraoperative pathology consultation was done. The diagnosis of bilateral XGS associated with chronic active follicular salpingitis was made. XGS is reported to be caused by an unsuccesfully treated pelvic inflammatory disease. Its association with chronic active follicular salpingitis has not been previously reported. Chronic active follicular salpingitis with xanthogranulomatous inflammation might give the impression of a cystic adnexal mass with septations on preoperative pelvic computed tomography. Frozen sections are necessary to rule out malignancy as done in our case. 相似文献

BACKGROUND: The objectives of this prospective study were: (i) to compare the efficacy of 1-week with 2-week pantoprazole-based triple therapy and (ii) to evaluate the impact of clarithromycin resistance on Helicobacter pylori (H. pylori) eradication rates. METHODS: Eighty dyspeptic patients were randomly allocated to two groups. The first group (PAC-1, n=40) received pantoprazole 40 mg, amoxicillin 1000 mg, and clarithromycin 500 mg twice a day for one week, and the second group (PAC-2, n=40) received the same regimen for two weeks. Endoscopy was repeated one month after the end of the treatment. RESULTS: DNA extraction for clarithromycin resistance could not be performed in seven cases. Five cases were lost to follow-up. Clarithromycin resistance was found to be 44.1% (15/34) in the PAC-1 group and 58.8% (20/34) in the PAC-2 group (p>0.05). Eradication was achieved in 16 (PP: 47.1%, ITT: 44.4%) and 25 (PP:73.5%, ITT: 67.6%) patients in the PAC-1 and PAC-2 groups, respectively (p>0.05). H. pylori was eradicated in 4 of 15 (PP: 26.7%, ITT: 26.7%) clarithromycin-resistant patients in the PAC-1 group and in 12 of 20 (PP: 60%, ITT: 60%) clarithromycin-resistant patients in the PAC-2 group (p>0.05). Among the clarithromycin-sensitive ones, eradication was achieved in 12 of 19 (PP: 63.2%, ITT: 57.1%) patients in the PAC-1 group and in 13 of 14 (PP: 92.8%, ITT: 76.5%) patients in the PAC-2 group (p>0.05). CONCLUSION: Although the 2-week regimen of pantoprazole-based triple therapy was effective for H. pylori eradication in clarithromycin-sensitive cases, highly effective H. pylori eradication protocols are needed for clarithromycin-resistant ones. 相似文献
