RESUMO
BACKGROUND AND AIMS: In patients with noncirrhotic chronic extrahepatic portal vein obstruction (EHPVO), data on the morbimortality of abdominal surgery are scarce. APPROACH AND RESULTS: We retrospectively analyzed the charts of 76 patients (78 interventions) with EHPVO undergoing abdominal surgery within the Vascular Disease Interest Group network. Fourteen percent of the patients had ≥1 major bleeding (unrelated to portal hypertension) and 21% had ≥1 Dindo-Clavien grade ≥3 postoperative complications within 1 month after surgery. Fifteen percent had ≥1 portal hypertension-related complication within 3 months after surgery. Three patients died within 12 months after surgery. An unfavorable outcome (ie, ≥1 abovementioned complication or death) occurred in 37% of the patients and was associated with a history of ascites and with nonwall, noncholecystectomy surgical intervention: 17% of the patients with none of these features had an unfavorable outcome, versus 48% and 100% when one or both features were present, respectively. We then compared 63/76 patients with EHPVO with 126 matched (2:1) control patients without EHPVO but with similar surgical interventions. As compared with control patients, the incidence of major bleeding ( p <0.001) and portal hypertension-related complication ( p <0.001) was significantly higher in patients with EHPVO, but not that of grade ≥3 postoperative complications nor of death. The incidence of unfavorable postoperative outcomes was significantly higher in patients with EHPVO than in those without (33% vs. 18%, p =0.01). CONCLUSIONS: Patients with EHPVO are at high risk of major perioperative or postoperative bleeding and postoperative complications, especially in those with ascites or undergoing surgery other than wall surgery or cholecystectomy.
RESUMO
BACKGROUND & AIMS: Nonalcoholic fatty liver disease (NAFLD) may be a risk factor for hepatocellular carcinoma (HCC), but the extent of this association still needs to be addressed. Pooled incidence rates of HCC across the disease spectrum of NAFLD have never been estimated by meta-analysis. METHODS: In this systematic review, we searched Web of Science, Embase, PubMed, and the Cochrane Library from January 1, 1950 through July 30, 2020. We included studies reporting on HCC incidence in patients with NAFLD. The main outcomes were pooled HCC incidences in patients with NAFLD at distinct severity stages. Summary estimates were calculated with random-effects models. Sensitivity analyses and meta-regression analyses were carried out to address heterogeneity. RESULTS: We included 18 studies involving 470,404 patients. In patients with NAFLD at a stage earlier than cirrhosis, the incidence rate of HCC was 0.03 per 100 person-years (95% confidence interval [CI], 0.01-0.07; I2 = 98%). In patients with cirrhosis, the incidence rate was 3.78 per 100 person-years (95% CI, 2.47-5.78; I2 = 93%). Patients with cirrhosis undergoing regular screening for HCC had an incidence rate of 4.62 per 100 person-years (95% CI, 2.77-7.72; I2 = 77%). CONCLUSIONS: Patients with NAFLD-related cirrhosis have a risk of developing HCC similar to that reported for patients with cirrhosis from other etiologies. Evidence documenting the risk in patients with nonalcoholic steatohepatitis or simple steatosis is limited, but the incidence of HCC in these populations may lie below thresholds used to recommend a screening. Well-designed prospective studies in these subpopulations are needed. The protocol for this systematic review is registered in the Prospero database (registration number CRD42018092861).

OBJECTIVES: Preoperative consultation is usually not performed before insertion of a totally implantable venous access device (TIVAD). In our experience, an incomplete preoperative assessment, a predictable medical condition contraindicating surgery, or no-show patients the day of surgery led to several surgery cancellations. Therefore, we introduced a specific preoperative surgical consultation for TIVAD that took place shortly before surgery. The aim of the present study is to evaluate the patients' satisfaction and to establish the rate of cancellation after the adoption of this strategy. METHODS: Two-hundred and four patients who benefited from the preoperative consultation before TIVAD insertion from August 2014 to August 2016 were included. Satisfaction of patients and cancellation rate were documented. RESULTS: With that strategy, no TIVAD insertion was either delayed or cancelled. The overall level of satisfaction was high (91.8%); 184 patients (90.2%) judged the consultation useful in preparation for the surgery. The surgical procedure met their expectations in 92.2% of cases. Patients known for a psychiatric comorbidity were more likely to express dissatisfaction. CONCLUSIONS: The introduction of a specific preoperative surgical consultation for TIVAD insertion led to a high level of patients' satisfaction. After the preoperative consultation, no cancellation was recorded. Special approaches have to be considered for patients with a psychiatric comorbidity.

Abdominal pain and liver injury have been frequently reported during coronavirus disease-2019 (COVID-19). Our aim was to investigate characteristics of abdominal pain in COVID-19 patients and their association with disease severity and liver injury.Data of all COVID-19 patients hospitalized during the first wave in one hospital were retrieved. Patients admitted exclusively for other pathologies and/or recovered from COVID-19, as well as pregnant women were excluded. Patients whose abdominal pain was related to alternative diagnosis were also excluded.Among the 1026 included patients, 200 (19.5%) exhibited spontaneous abdominal pain and 165 (16.2%) after abdomen palpation. Spontaneous pain was most frequently localized in the epigastric (42.7%) and right upper quadrant (25.5%) regions. Tenderness in the right upper region was associated with severe COVID-19 (hospital mortality and/or admission to intensive/intermediate care unit) with an adjusted odds ratio of 2.81 (95% CI 1.27-6.21, p = 0.010). Patients with history of lower abdomen pain experimented less frequently dyspnea compared to patients with history of upper abdominal pain (25.8 versus 63.0%, p < 0.001). Baseline transaminases elevation was associated with history of pain in epigastric and right upper region and AST elevation was strongly associated with severe COVID-19 with an odds ratio of 16.03 (95% CI 1.95-131.63 p = 0.010).More than one fifth of patients admitted for COVID-19 presented abdominal pain. Those with pain located in the upper abdomen were more at risk of dyspnea, demonstrated more altered transaminases, and presented a higher risk of adverse outcomes.

Two years after a Hartmann's procedure, an 85-year-old woman was admitted at our emergency department with abdominal bloating and severe constipation for 5 days. Abdominal CT showed a large rectal stump mucocele associated with compression of surrounding structures, causing a mechanical ileus and a bilateral pyelocaliceal dilatation. Successful transanal drainage with a rectal catheter allowed rapid recovery.

BACKGROUND: Ehlers-Danlos syndrome (EDS) is a heterogeneous group of rare inherited diseases involving connective tissue. Vascular EDS (vEDS) is associated with abnormal type III collagen, which is an essential component of skin, hollow organs and arterial walls, and causes potentially fatal visceral and arterial complications. The surgical management of these patients is challenging and should be limited to life-saving procedures. CASE DESCRIPTION: We report a case of a 42-year-old male who presented a hemorrhagic shock due to spontaneous rupture of an ascending branch of the left colic artery. The coexisting presence of multiple abdominal vascular abnormalities suggested the diagnosis of vEDS, later confirmed by the discovery of a new missense mutation in the COL3A1 gene with pathogenic significance. The post-operative course was marked by a mechanical ileus caused by an ischemic stenosis of the descending colon. Failure of conservative management and the well-known risk of colonic perforation in these patients led to the decision to perform a diverting ileostomy. CONCLUSION: The management of these patients is difficult, and risk-benefit assessments must be made on a case-by-case basis. Less invasive procedures should be considered whenever possible.

BACKGROUND: Cryptococcosis is a frequent complication in immunosuppressed patients, causing mainly central nervous system and lung infection, and leading to increased mortality risk. CASE PRESENTATION: We present the first documented case in Switzerland of Cryptococcus gattii pneumonia in a kidney-pancreas transplant patient, with a concomitant Pneumocystis jirovecii infection mimicking an immune reconstitution syndrome. Diagnosis of cryptococcal pneumonia was based on a positive serum cryptococcal antigen and confirmed by Grocott’s methenamine silver and periodic acid-Schiff stains on bronchoalveolar lavage fliud. C. gattii was identified with mass spectrometry and antifungal susceptibility testing by microdilution was performed. After an initial successful treatment with liposomal amphotericin-B, flucytosine and tapering of immunosuppression, the patient clinically deteriorated, developing bilateral diffuse ground-glass opacities with consolidations on chest computed tomography. A diagnosis of probable P. jirovecii pneumonia versus an immune reconstitution syndrome was considered. Because of a high titre of Pneumocystis on polymerase chain-reaction testing of bronchoalveloar lavage fluid and high serum b-D-glucan, a diagnosis of probable P. jirovecii pneumonia was made. CONCLUSION: This case illustrates the potential complications of a cryptococcal infection in immunosuppressed hosts, despite timely diagnosis and appropriate antifungal therapy.

BACKGROUND: Transplantation of kidneys from deceased donors is still associated with a high rate of postoperative renal dysfunction. During implantation into the recipient, the kidney rewarms. This second warm ischaemia time, which is not monitored, is harmful especially if prolonged. We recently developed an intra-abdominal cooling device that efficiently prevents kidney rewarming during robotic transplantation, and prevents ischaemia-reperfusion injuries. We tested the benefits of this cooling device during open kidney transplantation in pigs. METHODS: Kidneys were procured from large pigs by open bilateral nephrectomy. Following procurement, kidneys were flushed with 4°C Institut Georges Lopez-1 preservation solution, and placed on ice. Animals then underwent double sequential autologous open renal transplantation with (n = 7) and without (n = 6) intra-abdominal cooling. RESULTS: Mean anastomosis time was similar between groups (43.9 ± 13 minutes). At reperfusion, the renal cortex temperature was lower in the group with cooling (4.3 ± 1.1°C vs 26.5 ± 5.5°C, p <0.001). The cooled kidneys tended to be protected from injury, including some histopathological ischaemia-reperfusion lesions. With the device, kidneys had a better immediate postoperative urine output (p = 0.05). CONCLUSION: Our results indicate that the intra-abdominal cooling device significantly reduced second warm ischaemic time during transplantation, is technically safe and does not prolong anastomotic time.

Kidney transplantation (KT), as a modality of renal replacement therapy (RRT), has been shown to be both economically and functionally superior to dialysis for the treatment of end-stage renal disease (ESRD). Progress in KT is limited by two major barriers: a) a chronic and burgeoning shortage of transplantable organs and b) the need for chronic immunosuppression following transplantation. Although ground-breaking advances in transplant immunology have improved patient survival and graft durability, a new pathway of innovation is needed in order to overcome current obstacles. Regenerative medicine (RM) holds the potential to shift the paradigm in RRT, through organ bioengineering. Manufactured organs represent a potentially inexhaustible source of transplantable grafts that would bypass the need for immunosuppressive drugs by using autologous cells to repopulate extracellular matrix (ECM) scaffolds. This overview discusses the current status of renal transplantation while reviewing the most promising innovations in RM therapy as applied to RRT.
