    Abstract Background: The evidence supporting intensive blood glucose control to prevent surgical site infections (SSIs) among liver transplant recipients is insufficient. We aimed to assess the effects of postoperative intensive blood glucose control (IBGC) against standard blood glucose control (SBGC) on the incidence of SSIs among adult liver transplant recipients.
    Methods: We performed a randomized controlled trial (ClinicalTrials.gov identifier NCT03474666). The IBGC target was 80 to 130 mg/dL, and the SBGC target was below 180 mg/dL. Analyses were made on an intention-to-treat basis.
    Results: Of the 41 recipients enrolled onto the trial, 20 were randomly allocated to the IBGC group and 21 to the SBGC group. There were no significant differences in SSIs among recipients allocated to either group (relative risk [RR], 0.78; 95% confidence interval [CI], 0.21-2.88; P = .69). Mean (SD) blood glucose levels were significantly lower in the IBGC group in the 24-hour period after surgery (145.0 [20.7] mg/dL and 230.2 [51.6] mg/dL; P = .001). While there were fewer episodes of hypoglycemia in the IBGC group, this was not statistically significant. There were no episodes of severe hypoglycemia in either group. Hyperglycemia and severe hyperglycemia were significantly more frequent in the SBGC group (RR, 0.70; 95% CI, 0.52-0.93; P = .001 and RR, 0.07; 95% CI, 0.01-0.48; P = .001, respectively). Length of hospital stay was significantly shorter for recipients in the IBGC group (13.1 [5.5] days vs 19.3 [12.1] days; P = .04).
    Conclusions: Although this small trial did not find intensive control reduced SSI, it was associated with lower blood glucose levels, fewer episodes of hyperglycemia and severe hyperglycemia, and shorter length of hospital stay.

    Abstract Background: Surgical site infection is an important complication in the postoperative period among liver transplant recipients. However, little is known about the risk factors in this patient group. Therefore, the objective of this study was to analyze the incidence and risk factors for surgical site infections among adult liver transplant recipients.
    Methods: Medical records of adult liver transplant recipients from January 1, 2009, to December 31, 2015, were analyzed in this retrospective cohort study.
    Results: We enrolled 156 recipients' medical records. Forty-two (26.9%) cases of surgical site infections were identified. The main isolated microorganisms were methicillin-resistant Staphylococcus species, extended spectrum β-lactamase-producing Klebsiella species, carbapenem-resistant Pseudomonas aeruginosa, carbapenem-resistant Acinetobacter baumannii, and vancomycin-susceptible Enterococcus faecalis. We found that long operative times (≥487 minutes) and differences in body mass index between donor and recipient (≥1.3 kg/m
    Conclusions: There was a high incidence of surgical site infections among the studied population and that some risk factors identified differ from those reported in the scientific literature.

    Abstract Encapsulating Peritoneal Sclerosis (EPS) is a severe and rare condition frequently associated with peritoneal dialysis, characterized by bowel obstruction, with lethal consequences in 20% of the patients. The disease presents as a mass of fibrous tissue encapsulating visceral organs that may potentially compromise digestive tract function. This report describes the case of a patient under peritoneal dialysis (PD) due to chronic kidney disease secondary to focal segmental glomerulosclerosis diagnosed with EPS. The patient had undergone two living-donor kidney transplant procedures. Surgical techniques and clinical measures employed to unravel bowel obstruction are described, which have been shown to ameliorate EPS secondary complications. Parenteral nutrition has significantly contributed to afford adequate nutrition, improving tissue healing as well as serum protein levels, vitamins and electrolytes. Therapy with tamoxifen and sodium thiosulfate effectively delayed the development of EPS.

    Abstract Background: Infections by SARS-CoV-2 in liver transplant recipients (LT) patients are of particular concern, notably due to perceived added risks related to immunosuppression and comorbidity burden. Current literature on this topic often relies on small, non-standardized, and geographically limited studies. This manuscript describes COVID-19 presentations and causes for elevated mortality in a large cohort of LT recipients.
    Methods: This study was designed as a multicentric historical cohort, including LT recipient patients with COVID-19 in 25 study centers, with the primary endpoint being COVID-related death. We also collected demographic, clinical, and laboratory data regarding presentation and disease progression.
    Results: Two hundred and thirty-four cases were included. The study population was predominantly male and White and had a median age of 60 years. The median time from transplantation was 2.6 years (IQR 1-6). Most patients had at least one comorbidity (189, 80.8%). Patient age (P = .04), dyspnea (P < .001), intensive care unit admission (P < .001), and mechanical ventilation (P < .001) were associated with increased mortality. Modifications of immunosuppressive therapy (P < .001), specifically the suspension of tacrolimus, maintained significance in multivariable analysis.
    Conclusions: Attention to risk factors and the individualization of patient care, especially regarding immunosuppression management, is crucial for delivering more precise interventions to these individuals.

    Abstract Background: A crucial aspect of living-donor liver transplant is the risk imposed to the donor due to a procedure performed in a healthy individual that can lead to a high postoperative morbidity rate
    Aim: To correlate the pre- and intraoperative hepatic imaging findings of living adult donors.
    Methods: From 2003 to 2008 the medical charts of 66 donors were revised; in that, 42 were males (64%) and 24 females (36%), mean age of 30 ± 8 years. The preoperative anatomy was analyzed by magnetic resonance cholangiography to study the bile ducts and by computed tomography angiography to evaluate the hepatic artery and portal vein. Normalcy criteria were established according to previously published studies.
    Results: Anatomic variations of the bile ducts were found in 59.1% of donors, of the artery hepatic in 31.8% and of the portal vein in 30.3% of the cases during the preoperative period. The magnetic resonance cholangiography findings were in agreement in 44 (66.6%) of donors and in disagreement in 22 (33.3%). With regards to hepatic artery, in all donors the findings of the imaging examination were in agreement with those of the intraoperative period. As to the portal vein, the computed tomography findings were in agreement in 59 (89.4%) donors and in disagreement in seven (10.6%).
    Conclusions: The bile duct anatomic variations are frequent, and the magnetic resonance cholangiography showed moderate accuracy (70%) in reproducing the surgical findings; the computed tomography reproduced the intraoperative findings of the hepatic artery in 100% of donors, and of the portal vein in 89.4% of the cases, thus demonstrating high accuracy (89%).

    Abstract Background: In this study we retrospectively evaluated a group of symptomatic cirrhotic (n=30) and non-cirrhotic (n=60) patients submitted to laparoscopic cholecystectomy (LC) in a public hospital in Brazil.
    Methods: The groups were compared for surgical time, duration of hospitalization after surgery, period of permanence in the intensive care unit (ICU), use of blood derivatives, mortality rates, and transoperative and post-surgery complications. Other parameters, such as hepatic reserve capacity and presence of ascites, were also analyzed.
    Results: Twenty-three (76.7%) of the patients of the cirrhosis group (CG) were classified as Child-Pugh A, and seven (23.3%) were Child-Pugh B. Six of them (20%) had ascites. Differences between the two groups included surgery time (p=0.008), duration of hospitalization (p=0.014), and post-surgery (p=0.000) or ambulatory (p=0.008) complications. The worst results were observed among Child B patients and in those with ascites. Blood derivatives were used in only 3.3% of the CG patients. No cases of conversion to laparotomy were observed among the two groups of patients included in this study, nor were there any deaths.
    Conclusions: These results indicate that videolaparoscopic cholecystectomy may be safely performed in public hospitals in Brazil, with low levels of complications, no associated mortality, and no need for blood derivatives.

    Abstract Background: For living-related liver transplantation, harvesting a right hepatic graft that includes the middle hepatic vein (MHV) has been recommended to improve venous drainage of the graft. However, it may result in congestion of the donor's remaining segment IV, increasing the potential risk to the donor. This study aimed to compare safety levels for liver donors during procedures with or without removal of the MHV.
    Methods: A total of 68 living donor liver transplantations were performed from March 2001 to May 2007. In 39 procedures, the MHV was not included in the graft (group A), and in 29 the MHV was included in the graft (group B). The analyzed data included surgical time, use of blood derivatives, length of hospital stay, laboratory analyses, weight of the graft, and clinical complications.
    Results: No differences were observed regarding the need for blood derivatives or laboratory parameters. The frequency of postoperative complications was similar in the two groups, with 10 cases (25.6%) in group A and 7 cases (24.1%) in group B (P=0.887). No deaths were seen. The rate of observed complications was 25% among living donors, most of them being managed without surgical intervention.
    Conclusions: The inclusion of the MHV does not add morbidity in living donors in selected cases.

    Abstract New therapeutic options for obesity include restrictive bowel surgery and surgery that promotes malabsorption, such as the Fobi-Capella (gastric bypass) and Scopinaro (biliopancreatic diversion) techniques. Complications associated with these procedures, such as hepatocellular failure, have been observed with increasing frequency. Reported here are 3 patients who, 7 to 24 months after bariatric surgery, developed hepatocellular failure, for which liver transplantation was considered to be indicated. Liver transplantation was undertaken in 2 of the patients; the third patient died while waiting for this procedure. We discuss the possible causes of this uncommon and poorly understood complication of surgery for obesity. One possibility is that it might arise as a result of progression of steatohepatitis. An alternative concept is that this complication may be secondary to rapid, massive loss of body weight.
