Randomized clinical trial of pancreaticogastrostomy versus pancreaticojejunostomy on the rate and severity of pancreatic fistula after pancreaticoduodenectomy.

BACKGROUND: Anastomotic leakage of pancreaticojejunostomy (PJ) remains the single most important source of morbidity after pancreaticoduodenectomy (PD). The primary aim of this randomized clinical trial comparing PG with PJ after PD was to test the hypothesis that invaginated PG would result in a lower rate and severity of pancreatic fistula. METHODS: Patients undergoing PD were randomized to receive either a duct-to-duct PJ or a double-layer invaginated PG. The primary endpoint was the rate of pancreatic fistula, using the definition of the International Study Group on Pancreatic Fistula. Secondary endpoints were the evaluation of severe abdominal complications (Clavien-Dindo grade IIIa or above), endocrine and exocrine function. RESULTS: Of 123 patients randomized, 58 underwent PJ and 65 had PG. The incidence of pancreatic fistula was significantly higher following PJ than for PG (20 of 58 versus 10 of 65 respectively; P = 0.014), as was the severity of pancreatic fistula (grade A: 2 versus 5 per cent; grade B-C: 33 versus 11 per cent; P = 0.006). The hospital readmission rate for complications was significantly lower after PG (6 versus 24 per cent; P = 0.005), weight loss was lower (P = 0.025) and exocrine function better (P = 0.022). CONCLUSION: The rate and severity of pancreatic fistula was significantly lower with this PG technique compared with that following PJ.

Corticosteroids and tocilizumab reduce in-hospital mortality in severe COVID-19 pneumonia: a retrospective study in a Spanish hospital.

BACKGROUND: There is an urgent need to reduce mortality of COVID-19. We examined if corticosteroids and tocilizumab reduce risk for death in patients with severe pneumonia caused by SARS-CoV-2. METHODS: A retrospective cohort study was performed in a single university hospital. All adult patients admitted with confirmed severe COVID-19 pneumonia from 9 March to 9 April 2020 were included. Severe pneumonia was defined as multi-lobar or bilateral pneumonia and a ratio of oxygen saturation by pulse oximetry to the fraction of inspired oxygen (SpFi)<315. All patients received antiviral and antibiotic treatment. From March 26, patients also received immunomodulatory treatment with corticosteroids (methylprednisolone 250 mg/day for 3 days), or tocilizumab or both. In-hospital mortality in the entire cohort and in a 1:1 matched cohort sub-analysis was evaluated. RESULTS: 255 patients were included, 118 received only antiviral and antibiotic treatment while 137, admitted after March 26, also received immunomodulators. In-hospital mortality of patients on immunomodulatory treatment was significantly lower than in those without [47/137(34.3%) vs. 69/118(58.5%), (p < .001)]. The risk of death was 0.44 (CI, 0.26-0.76) in patients receiving corticosteroids alone and 0.292 (CI, 0.18-0.47) in those treated with corticosteroids and tocilizumab. In the sub-analysis with 202 matched patients, the risk of death was 0.356 (CI 0.179-0.707) in patients receiving corticosteroids alone and 0.233 (0.124-0.436) in those treated with the combination. CONCLUSIONS: Combined treatment with corticosteroids and tocilizumab reduced mortality with about 25% in patients with severe COVID-19 pneumonia. Corticosteroids alone also resulted in lower in-hospital mortality rate compared to patients receiving only antiviral and antibiotic treatment. Corticosteroids alone or combined with tocilizumab may be considered in patients with severe COVID-19 pneumonia.

Extreme liver surgery as treatment of liver tumors involving the hepatocaval confluence.

OBJECTIVE: Analyze the characteristics, surgical technique, morbidity and survival of patients treated with extreme liver surgery. MATERIALS AND METHODS: We present a series of consecutive patients with malignant liver tumors in hepatocaval confluence treated in a single center with extreme liver surgery (April 2008-March 2015). Data were collected prospectively and analyzed with SPSS 21.0. RESULTS: 12 patients were included. 50 % were male and 50 % were female with a mean age of 59 ± 10 years old. The median of comorbidities was 7 according to the Charlson Age Comorbidity Index. The 75 % of the tumors were metastases, most of them from colorectal cancer. Most of the patients received neoadjuvant chemotherapy and in 58 % preoperative portal embolization was performed. Major hepatectomies were performed (66.7 % extended right hepatectomy, 33.3 % left extended hepatectomy). The 83.3 % of the patients needed vascular reconstruction. Postoperative morbidity was more than grade II in 50 % of the patients according to Dindo-Clavien classification. There was no intraoperative mortality. The postoperative mortality rate at 90 days was 33 % due to hepatic failure and biliary fistula. In December 2015, 33 % of the patients are still alive with a mean survival of 19 months (13-23) with an ECOG Performance Status of 0. CONCLUSION: Extreme liver surgery carries a high rate of morbidity and mortality that seem to increase with age and with higher tumor volumes, according to the literature. It is a therapeutic option to consider in patients with low comorbidity suffering from malignant neoplasms that involve the hepatocaval confluence, when no other treatment with curative intention can be performed.

[The characteristics of arterial hypertension in the population of a preventive medicine service]. / Características de la hipertensión arterial en la población de un servicio de medicina preventiva.

Of 2,115 persons who were submitted to a voluntary check-up, we found 10.6% suffering from hypertension and 16.2% with borderline hypertension, the latter group having been followed and the condition subsequently confirmed in 45.9% of the case. The prevalence increases with age. There were no prevailing differences found between rural and city populations. The prevalence is greater in self-employed persons that in salary workers and we would bring to the fore the higher prevalence in housewives (p less than 0.0005). 74.8% of the hypertensive patients knew of their situation but only 15.6% of them showed normal blood pressure at the following-up. Rarely 0.85% had severe hypertension and 3% had moderate hypertension.

Early prosthetic joint infection: outcomes with debridement and implant retention followed by antibiotic therapy.

Recent expert reviews recommend a conservative surgical strategy - debridement and irrigation, antibiotics and implant retention (DAIR) - for most early post-surgical prosthetic joint infections (PJI). However, differences exist in published series regarding success rates with DAIR, and the size of most series is small. In this prospective multicenter cohort study of early PJI managed by DAIR, factors associated with failure of the DAIR were analyzed. Out of 139 early PJI, 117 cases managed with DAIR were studied For 67 patients (57.3%), infection was cured and the implant was salvaged with definite antimicrobial therapy. In 35 (29.9%) DAIR failed and removal of the prosthesis was necessary during follow-up. Finally, 15 patients (12.8%) needed chronic suppressive antimicrobial therapy due to suspected or confirmed persistent infection. Infections due to methicillin-resistant S. aureus (72.7% failed; p 0.05) and those treated at one of the hospitals (80.0% failed; p <0.05) had worse outcomes, but only this last variable was associated with treatment failure following multivariate analysis. Seventy-four per cent of patients who were successfully treated by DAIR and only 32.7% of the failures were able to walk without help or with one stick at the last follow-up visit (p <0.05). In conclusion, a substantial proportion of patients with an early PJI may be successfully treated with DAIR and definite antimicrobial therapy. In more than half of these, the infection can be cured. Since identification of factors associated with failure of DAIR is not simple, we recommend offering DAIR to most patients with early PJI.
