    Abstract Objective: To describe our technique of simultaneous hand-assisted laparoscopic bilateral native nephrectomy (BNN) and kidney transplantation (KT) in patients with autosomal dominant polycystic kidney disease and present our experience.
    Materials and methods: We retrospectively reviewed a cohort of adult ESRD patients with symptomatic autosomal dominant polycystic kidney disease who underwent a hand-assisted laparoscopic BNN at the time of KT. We reviewed patients' and donor characteristics, and perioperative and postoperative outcomes.
    Results: A total of 52 patients underwent hand-assisted laparoscopic BNN at the time of KT from January 2014 to October 2019. The median age of the recipients was 53.4 years, 57.7% were males, and the median body mass index was 29.0 kg/m
    Conclusion: Simultaneous hand-assisted laparoscopic bilateral nephrectomy with KT through a modified Gibson incision is feasible and safe in the hands of an experienced laparoscopic surgeon without compromising allograft function.

    Abstract Purpose: Bilateral nephrectomy is performed at times with renal transplantation. Though surgical indications and timing of these two procedures have been described, there are no large case series describing the anesthetic management of these cases. We sought to describe our experience.
    Methods: We performed a historical cohort study on 54 consecutive cases of simultaneous bilateral nephrectomy with renal transplantation at a single, tertiary-care medical centre. Descriptive statistics were used.
    Results: The most common etiology of kidney disease involved was autosomal dominant polycystic kidney disease at 52/54 (96%) cases. All patients received grafts from living donors. An arterial line was placed in 44 (81%) and a central venous catheter in 16 (30%) subjects. At least one vasopressor infusion was used in 44 (81%) cases and 37 (69%) patients required admission to the intensive care unit (ICU). Of this subset, 30 (81%) were admitted for ongoing vasopressor support and six (16%) for hemodynamic monitoring. All patients were extubated in the operating room upon completion of the procedure. Median [interquartile range (IQR)] ICU length of stay (LOS) was 0.9 [0.7-1.4] days and total hospital LOS was 4.4 [4.3-5.4] days. There were no cases of mortality at 30 days or of postoperative dialysis.
    Conclusions: Adult patients undergoing simultaneous bilateral nephrectomy with renal transplantation often developed perioperative hypotension requiring vasopressor infusions and postoperative transfer to the ICU. This is possibly due to a temporary loss of the renin-angiotensin system. Despite this, patients most commonly were transferred to the floor on postoperative day 1 and had successful outcomes with no mortality at 30 days.

    Abstract Objective: Kidney transplant recipients are at lifetime risk of requiring high acuity care. In the current study, we aimed to assess the reasons for delayed (> 30 days) intensive care unit (ICU) admissions post-transplant and causes of ICU-related mortality.
    Methods: This is a retrospective study of a cohort of adult kidney transplant patients from January 1, 2007, through December 31, 2016, who required ICU admission after 30 days of transplantation. The admissions were divided into 3 groups based on their timeline between transplantation and ICU admission: 1. group 1 from 30 days to 6 months, 2. group 2 between 6-24 months, and 3. group 3 after 2 years. All admissions were categorized according to the primary organ system involved.
    Results: A total of 285 (group 1: 50, group 2: 89, group 3: 146) patients required 404 ICU admissions (group 1: 57, group 2: 108, group 3: 239). Overall, cardiovascular system-related admissions (29.9%, 18.5%, 15.9%), infections (19.3%, 25.9%, 27.2%), and respiratory-related admissions (12.3%, 8.3%, 8.8%) were main causes in all 3 groups. A total of 24 (8.4%) patients died in the ICU. Most of the deaths occurred in men (79.2%), infection-related admissions (45.8%), and individuals with a functioning allograft (66.7%). Infections (45.8%) were the main causes of ICU-related mortality. Median time from transplantation to death was 2.3 years (interquartile range: 1.2-4.6).
    Conclusion: Kidney transplant patients continue to be at risk of requiring high acuity care long after transplantation. Most of these admissions are related to cardiopulmonary system involvement or infections. Overall, infections were the leading cause of ICU-related mortality.

    Abstract Purpose: The present study aims to assess the results obtained after surgical treatment of cholangiocarcinoma (CC) recurrences.
    Methods: We carried out a single-center retrospective study, including all patients with recurrence of CC. The primary outcome was patient survival after surgical treatment compared with chemotherapy or best supportive care. A multivariate analysis of variables affecting mortality after CC recurrence was performed.
    Results: Eighteen patients were indicated surgery to treat CC recurrence. Severe postoperative complication rate was 27.8% with a 30-day mortality rate of 16.7%. Median survival after surgery was 15 months (range 0-50) with 1- and 3-year patient survival rates of 55.6% and 16.6%, respectively. Patient survival after surgery or CHT alone, was significantly better than receiving supportive care (p< 0.001). We found no significant difference in survival when comparing CHT alone and surgical treatment (p=0.113). Time to recurrence of <1 year, adjuvant CHT after resection of the primary tumor and undergoing surgery or CHT alone versus best supportive care were independent factors affecting mortality after CC recurrence in the multivariate analysis.
    Conclusion: Surgery or CHT alone improved patient survival after CC recurrence compared to best supportive care. Surgical treatment did not improve patient survival compared to CHT alone.

    Abstract Patients with autosomal dominant polycystic disease (ADPKD) may require bilateral nephrectomy (BN) in addition to kidney transplantation (KT) for symptom control. This study aims to compare simultaneous BNKT to contemporaneous controls by reviewing our cohort of ADPKD patients who underwent KT from a living donor from January 2014 to October 2019. Symptomatic patients who underwent laparoscopic BNKT were compared to KT alone. Clinical differences related to undertaking bilateral nephrectomies showed increased total kidney volumes (P < .001). We assessed operative parameters, complications, and clinical outcomes. The complications were classified according to the Clavien-Dindo system. In 148 transplant recipients, 51 underwent BNKT, and 97 KT alone. There was no difference in baseline demographics. BNKT recipients had longer cold ischemia time, required more ICU care, increased blood transfusions and longer hospital stays. The kidney function was similar in the first year in both groups, with no difference in delayed graft function, readmissions or severe grade III and IV complications within 3 months after surgery. Laparoscopic BNKT is safe and feasible at the time of living donor KT. Although higher acuity care is needed with a longer initial hospital stay, there are comparable posttransplant patient and allograft outcomes.
