Robotic living donor hepatectomy is associated with superior outcomes for both the donor and the recipient compared with laparoscopic or open - A single-center prospective registry study of 3448 cases.

Minimally invasive donor hepatectomy is an emerging surgical technique in living donor liver transplantation (LDLT). We examined outcomes across open, laparoscopic, and robotic LDLT using a prospective registry. We analyzed 3448 cases (1724 donor-recipient pairs) from January 2011 to March 2023 (NCT06062706). Among donors, 520 (30%) were female. Adult-to-adult LDLT comprised 1061 (62%) cases. A total of 646 (37%) of the donors underwent open, 165 (10%) laparoscopic, and 913 (53%) robotic hepatectomies. Primary outcomes: donor overall morbidity was 4% (35/903) for robotic, 8% (13/165) laparoscopic, and 16% (106/646) open (P < .001) procedures. Pediatric and adult recipient mortality was similar among the 3 donor hepatectomy approaches: robotic 1.5% and 7.0%, compared with 2.3% and 8.3% laparoscopic, and 1.6% and 5.5% for open donor surgery, respectively (P = .802, P = .564). Secondary outcomes: pediatric and adult recipients major morbidity after robotic hepatectomy was 15% and 23%, compared with 25% and 44% for laparoscopic surgery and 19% and 31% for open surgery, respectively (P = .033, P < .001). Graft and recipient 5-year survival were 90% and 93% for pediatrics and 79% and 80% for adults, respectively. In conclusion, robotic LDLT was associated with superior outcomes when compared with the laparoscopic and open approaches. Both donors and, for the first time reported, recipients benefitted from lower morbidity rates in robotic surgery, emphasizing its potential for further advancing this field.

Robotic surgery and liver transplantation: A single-center experience of 501 robotic donor hepatectomies.

BACKGROUND: Over the past two decades robotic surgery has been introduced to many areas including liver surgery. Laparoscopic liver surgery is an alternative minimally invasive approach. However, moving on to the complexity of living donor hepatectomies, the advantages of robotic versus laparoscopic approach have convinced us to establish the robotic platform as a standard for living donor hepatectomy. METHODS: From November 2018 to January 2022, 501 fully robotic donor hepatectomies, including 177 left lateral donor lobes, 112 full left lobes and 212 full right lobes were performed. Grafts were donated to 296 adult recipients and 205 pediatric recipients. Donor age, sex, body weight, body mass index (BMI), graft weight, graft to body weight ratio (GBWR), operative time, blood loss, first warm ischemic time, pain score, length of intensive care unit (ICU) stay and hospital stay, and complications were retrospectively analyzed based on a prospectively kept database. Recipients were evaluated for graft and patient survival, age, sex, BMI, body weight, model of end-stage liver disease score, blood loss, transfusions, operative time, cold ischemic time, length of hospital stay and complications. RESULTS: There was no donor mortality. Two cases needed to be converted to open surgery. The median blood loss was 60 mL (range 20-800), median donor operative time was 6.77 h (range 2.93-11.53), median length of hospital stay was 4 days (range 2-22). Complication rate in donors classified following Clavien-Dindo was 6.4% (n = 32) with one grade III complication. Three-year actual recipient overall survival was 91.4%; 87.5% for adult recipients and 97.1% for pediatric recipients. Three-year actual graft overall survival was 90.6%; 87.5% for adult recipients and 95.1% for pediatric recipients. In-hospital mortality was 6%, 9.1% (27/296) for adult recipients and 1.4% (3/205) for pediatric recipients. The recipients' morbidity was 19.8% (n = 99). Twenty-eight recipients (5.6%) had biliary and 22 (4.4%) vascular complications. Six (12.0%) recipients needed to be re-transplanted. CONCLUSIONS: With growing experience it is nowadays possible to perform any donor hepatectomy by robotic approach regardless of anatomical variations and graft size. Donor morbidity and quality for life results are encouraging and should motivate other transplant centers with interest in minimally invasive donor surgery to adopt this robotic technique.

Living donor liver transplantation in septuagenarians: Better late than never.

BACKGROUND: The coupling of increased life expectancy and improvements in both quality and access to chronic liver disease care, is culminating in an expanding population of septuagenarians (≥70 years) in need of liver transplantation (LT). The objective of this study is to partially alleviate this knowledge deficit and to add clarity to the current status and role of LDLT in this recipient population. METHODS: Of 295 adult patients underwent LDLT between January 1, 2011 and December 31, 2016. Twelve (4%) of these patients were septuagenarians and this group was compared to younger cohort (n = 283). RESULTS: Comorbidity profiles between the two groups were similar and no statistically significant differences were noted in warm/cold ischemia times, operative duration, or blood product utilization. ICU and total hospital stays were comparable. Septuagenarian 1-and 5-year graft and patient survivals were identical at 91.7%. Their younger counterparts had 1-and 5-year patient survivals of 91.1% and 84.0 % accompanied by 1-and 5-year graft survivals of 89.8% and 82.7%, respectively. CONCLUSION: Our study highlights a recognition that LDLT can afford highly-selected elderly patients to access to transplant with equivalent outcomes to those realized by younger recipients.

Changing trends in liver transplantation indications in Saudi Arabia: from hepatitis C virus infection to nonalcoholic fatty liver disease.

BACKGROUND: Several trend analyses on liver transplantation (LT) indications have been published in the U.S. and in other countries, but there are limited data on LT indication trends in Saudi Arabia (SA), especially since the availability of direct-acting antivirals (DAAs) treatment for hepatitis C virus (HCV). This study aimed to analyze trends in the frequency of LT indications among LT recipients in SA over a 19-year period and examine associations between etiologic-specific trends and clinicodemographic characteristics. METHODS: This retrospective study analyzed clinical and surgical data of adult patients (n = 1009) who underwent LT at the King Faisal Specialist Hospital & Research Center (Riyadh, SA) between 2001 and 2019. Spearman's rank correlation, Poisson regression, and Joinpoint regression analysis were employed to assess changes in LT etiologic trends. RESULTS: In the first period (2001-2010), the main LT indications were HCV (41.9%) and hepatitis B virus (HBV) (21.1%), but nonalcoholic steatohepatitis (NASH) (29.7%) surpassed HCV (23.7%) as the leading LT indication in the second period (2011-2019); and the trends were significant in correlation analyses [incidence rate ratio (IRR) = 1.09 (1.06-1.13) for NASH; IRR = 0.93 (0.91-0.95) for HCV]. In the Joinpoint regression analysis, increases in NASH from 2006 to 2012 (+ 32.1%) were statistically significant, as were the decreases in HCV from 2004 to 2007 (- 19.6%) and from 2010 to 2019 (- 12.1%). Similar patterns were observed in LT etiological comparisons before and after the availability of DAAs and within hepatocellular carcinoma stratifications. CONCLUSIONS: Trends in the epidemiology of LT indications among LT recipients in SA have changed over a 19-year period. Most notably, NASH has eclipsed HCV in the country due to the effective treatment strategies for HCV. These trends in NASH now need an aggressive public health response to minimize and avert future onset of additional clinical and economic strains on health care systems and LT centers in SA.

Large for size in pediatrics liver transplant using left lateral segment grafts: A single center experience.

BACKGROUND: There are still controversies in using the large left lateral segment in pediatrics LT, with the possibility of the problem of LFS grafts, and the use of monosegmental or reduced liver grafts in small infants. This study aimed to evaluate our experience with LFSG in pediatrics LT. METHODS: A cohort retrospective analysis was conducted including pediatric recipients who underwent LT between January 2011 and October 2019. We compared recipients with GRWR ≥ 4% (LFS) vs GRWR < 4% as an average for size grafts. RESULTS: There were 331 pediatric LT, 74 patients with GRWR ≥ 4%, and 257 patients with GRWR < 4%. In the group of LFS grafts, temporary abdominal closure by silicon patch was done in 39 patients (52.7%), 2 patients (2.7%) had postoperative HAT, 3 patients (4.1%) early PVT, 1 patient (1.3%) bile leak, and 3 patients (4.1%) had wound infection, with no significant difference in these complications between the 2 groups. In patients with LFS- grafts, the 1-, 3-, 5-, and 7-year patients survival rates were 94.6%, 91.7%, 91.7%, and 91.7%, respectively, while the survival rates in patients of the other group were 96.1%, 92.6%, 91.9%, and 91.9%, respectively, with no significant difference (p = .85). CONCLUSION: Using LFS graft by left lateral segment in pediatric LT with potential delayed abdominal closure is a safe and feasible option with good outcomes and unnecessary need for graft reduction if performed by an experienced multidisciplinary team.

Robotic Versus Open Right Lobe Donor Hepatectomy for Adult Living Donor Liver Transplantation: A Propensity Score-Matched Analysis.

Robotic right lobe donor hepatectomy (RRLDH) is rarely performed, and data concerning its safety and efficacy are lacking. Here we compare our series of RRLDHs with a similar cohort undergoing open right lobe donor hepatectomy (ORLDH) with a propensity score-matched (PSM) analysis. Among 263 consecutive adult patients undergoing right lobe living donor hepatectomy from January 2015 until July 2019, 35 RRLDHs were matched to 70 ORLDHs. A 1:2 PSM analysis was performed to make the groups comparable for donor sex, age, and body mass index (BMI) and for recipient sex, age, BMI, Model for End-Stage Liver Disease score, and indication for transplant. Operative time was longer in RRLDHs compared with ORLDHs (504 ± 73.5 versus 331 ± 65.1 minutes; P < 0.001) but significantly decreased with the number of patients (P < 0.001). No conversions occurred. First warm ischemia time was longer and blood loss significantly less in RRLDHs (P = 0.001 and 0.003, respectively). Overall donor complications were similar: 2 (6%) in RRLDHs versus 12 (17%) in ORLDHs (P = 0.13). Biliary leak occurred in 1 (3%) patient receiving a robotic procedure and 2 (3%) patients receiving the conventional approach. Donors undergoing robotic surgery required less patient-controlled analgesia and had a shorter hospital stay compared with the open surgery group (P < 0.001 and P = 0.001, respectively). No significant differences in graft anatomical data and recipient outcomes were recorded. RRLDH is feasible, safe, and reproducible, with significantly decreased blood loss and a shorter hospital stay compared with the open procedure. The first 35 patients receiving the robotic procedure showed a substantial reduction in operative time, reflecting a rapid shortening of the learning curve.

Outcomes of Fully Robotic Recipient Living Donor Liver Transplant in Relation to the Open Approach.

BACKGROUND: Over the past 20 y, robotic surgery has entered nearly all surgical disciplines, aiming to improve patient outcomes. Liver transplantation has evolved with these advancements, and fully robotic liver transplants represent the latest innovation in this field. This study reports on the world's first series of fully robotic recipient liver transplants from robotic living donors, comparing them with matched cases from the standard open transplant approach. METHODS: A case-control study was conducted at our center from August to December 2023. Patient selection criteria for robotic recipient liver transplantation included a Model for End-stage Liver Disease score of ≤25, specific anatomical characteristics, and logistics. A propensity score analysis with a 1:4 matching ratio was used. RESULTS: The study analyzed 10 fully robotic living donor and robotic recipient liver transplant pairs with a median donor age of 29 y and a recipient age of 61 y. The main indication for transplantation was nonalcoholic steatohepatitis (6/10). There was 1 robotic to open conversion, and the median operation time was 10 h, with a median hospital stay of 13 d, shorter than the 18 d in the open group. Three recipients experienced a complication, and there was no mortality. CONCLUSIONS: The first-ever series of fully robotic living donor recipient liver transplants showed encouraging initial results with a markedly reduced hospital stay. The ultimate goal is to refine the technique to offer robotic liver transplants to the majority of recipients, overcoming the current selection criteria. Further research and a planned randomized controlled trial will aim to confirm these results.

Current status of indocyanine green fluorescent angiography in assessing perfusion of gastric conduit and oesophago-gastric anastomosis.

Anastomotic leak (AL) remains a significant complication after esophagectomy. Indocyanine green fluorescent angiography (ICG-FA) is a promising and safe technique for assessing gastric conduit (GC) perfusion intraoperatively. It provides detailed visualization of tissue perfusion and has demonstrated usefulness in oesophageal surgery. GC perfusion analysis by ICG-FA is crucial in constructing the conduit and selecting the anastomotic site and enables surgeons to make necessary adjustments during surgery to potentially reduce ALs. However, anastomotic integrity involves multiple factors, and ICG-FA must be combined with optimization of patient and procedural factors to decrease AL rates. This review summarizes ICG-FA's current applications in assessing esophago-gastric anastomosis perfusion, including qualitative and quantitative analysis and different imaging systems. It also explores how fluorescent imaging could decrease ALs and aid clinicians in utilizing ICG-FA to improve esophagectomy outcomes.

Diabetes mellitus is not associated with worse short term outcome in patients older than 65 years old post-liver transplantation.

BACKGROUND: Non-alcoholic fatty liver disease is a global health care challenge and a leading indication of liver transplantation (LT). Hence, more patients with diabetes mellitus (DM) are undergoing LT, especially, above the age of 65. AIM: To evaluate the impact of DM on short-term outcomes post-LT in patients over the age of 65. METHODS: We collected data of patients who underwent LT from January 2001 until December 2019 using our electronic medical record. We assessed the impact of DM on short-term outcomes, one-year, post-LT based on the following variables: Survival at one year; acute cellular rejection (ACR) rates; intensive care unit (ICU) and hospital length of stay; and readmissions. RESULTS: Total of 148 patients who are 65 year or older underwent LT during the study period. The mean age is 68.5 ± 3.3 years and 67.6% were male. The median Model for End-stage Liver Disease score at time of transplantation was 22 (6-39), 39% of patients had hepatocellular carcinoma and 77.7% underwent living donor LT. The one-year survival was similar between DM patients and others, 91%. ACR occurred in 13.5% of patients (P = 0.902). The median ICU stay is 4.5-day P = 0.023. The rates of ICU and 90-d readmission were similar (P = 0.821) and (P = 0.194), respectively. CONCLUSION: The short-term outcome of elderly diabetic patients undergoing LT is similar to others. The presence of DM in elderly LT candidates should not discourage physicians from transplant consideration in this cohort of patients.

Awareness, Attitudes, and Willingness: A Cross-Sectional Study of Organ Donation in Saudi Arabia.

BACKGROUND: Organ transplantation is inherently dependent on the availability of organ donors. There is a noticeable paucity of literature addressing the rates of organ donation registration and the awareness of Islamic regulations (Fatwa) regarding organ donation within Saudi Arabia. Our study aimed to evaluate the level of organ donation registration, awareness of Islamic regulations, and knowledge of the Saudi Center for Organ Transplantation (SCOT) within the Saudi society. METHODS: We conducted a cross-sectional survey from 30 March to 9 April 2023. This survey aimed to assess the awareness of Islamic (Fatwa) guidance on organ donation, the role of SCOT, and the rate of organ donation registration facilitated through the Tawakkalna app, the official health passport application in Saudi Arabia. RESULTS: Out of 2329 respondents, 21% had registered as potential deceased organ donors, despite 87% acknowledging the importance of organ donation. Awareness of the Islamic Fatwa regarding organ donation was reported by 54.7% of respondents, and 37% recognized the Fatwa's acceptance of brain death criteria. The likelihood of registration as organ donors was higher among Saudi citizens under 45 years of age, females, healthcare workers (HCWs), individuals with higher education, relatives of patients awaiting organ donations, those informed about the Islamic Fatwas, and those willing to donate organs to friends. Conversely, being over the age of 25, Saudi nationality, employment as an HCW, awareness of SCOT, and prior organ donation registration were predictive of a heightened awareness of Islamic Fatwas. However, perceiving the importance of organ donation correlated with a lower awareness of the Fatwas. Significant positive correlations were found between awareness of SCOT, awareness of Fatwas, and registration for organ donation. CONCLUSIONS: While the Saudi population exhibits a high regard for the importance of organ donation, this recognition is not adequately translated into registration rates. The discrepancy may be attributable to limited awareness of SCOT and the relevant Islamic Fatwas. It is imperative to initiate organ donation awareness campaigns that focus on religious authorization to boost organ donation rates and rectify prevalent misconceptions.

Efficacy and safety of once daily tacrolimus compared to twice daily tacrolimus after liver transplantation.

BACKGROUND: Once daily tacrolimus regimen was found to exhibits similar bioavailability, safety and efficacy properties compared to twice-daily tacrolimus in kidney transplantation patients. AIM: To compare the efficacy and safety of once-daily prolonged release tacrolimus compared to twice-daily tacrolimus in liver transplantation patients. METHODS: MEDLINE, EMBASE, CENTRAL databases were searched for clinical trials until December 2020. Efficacy outcome measured as the rate of treatment failure indicated by biopsy-proven acute rejection, Serum creatinine, graft loss, or death. Two reviewers independently selected studies, collected data and assessed risk of bias. The results are reported as risk ratio with 95% confidence interval (CI) for dichotomous data. RESULTS: Seven studies included with 965 patients. All the included studies were of moderate quality according to the risk of bias assessment using Cochrane Risk of Bias tool. Biopsy-proven acute rejection was reported in four studies, and pooled analysis of those studies indicated similar rejections in both twice daily and once daily tacrolimus groups (risk ratio: 1.06, 95%CI: 0.84-1.34, n = 758, I2 = 0%) and also we found no significant difference between both groups for renal outcome (serum creatinine; mean difference, 0.001 mg/dL, 95%CI: -0.042 to 0.043, n = 846, I2 = 18.6%). Similarly, there was similar number of adverse events such as hypertension, headache, back pain, blood related disorders, infections and nausea observed in both groups. CONCLUSION: The analysis findings confirm that both once daily and twice daily tacrolimus formulations are comparable in terms of efficacy and safety outcomes.

Safety and Feasibility Report of Robotic-assisted Left Lateral Sectionectomy for Pediatric Living Donor Liver Transplantation: A Comparative Analysis of Learning Curves and Mastery Achieved With the Laparoscopic Approach.

BACKGROUND: There is a growing interest in left lateral sectionectomy for donor hepatectomy. No data are available concerning the safety of the robotic (ROB) approach. METHODS: A retrospective comparative study was conducted on 75 consecutive minimally invasive donor hepatectomies. The first 25 ROB procedures performed from November 2018 to July 2019 were compared with our first (LAP1) and last 25 (LAP2) laparoscopic cases performed between May 2013 and October 2018. Short-term donors and recipients' outcomes were analyzed. RESULTS: No conversions were noticed in ROB whereas 2 conversions (8%) were recorded in LAP1 and none in LAP2. Blood loss was significantly less in ROB compared with LAP1 (P ≤ 0.001) but not in LAP2. Warm ischemia time was longer in ROB (P ≤ 0.001) with respect to the other groups. Operative time was similar in the 3 groups (P = 0.080); however, the hospital stay was shorter in ROB (P = 0.048). The trend in operative time in ROB was significantly shorter compared to LAP1 and LAP2: linear R2 0.478, P≤0.001; R2 0.012, P = 0.596; R3 0.004, P = 0.772, respectively. Donor morbidity was nihil in ROB, similar in LAP1 and LAP2 (n=3%-12%; P = 0.196). ROB procedures required less postoperative analgesia (P = 0.002). Recipient complications were similar for all groups (P = 0.274), and no early retransplantations were recorded. CONCLUSIONS: Robotic left lateral sectionectomy for donor hepatectomy is a safe procedure with results comparable to the laparoscopy in terms of donor morbidity and overall recipients' outcome when the procedure is performed by experts. Certainly, its use is currently very limited.

Validating controlled attenuation parameter in the assessment of hepatic steatosis in living liver donors.

INTRODUCTION: Hepatic steatosis (HS) negatively impacts transplant outcomes in living liver donors. To date, liver biopsy is preferred for HS evaluation. This study aims to evaluate the measurement of controlled attenuation parameter (CAP) as a diagnostic tool of HS in living liver donors. METHODS: Candidates recruited to this study, conducted from April 2016 to February 2020, were potential donors who had undergone transient elastography using Fibroscan® and CAP measurements at liver segments VI and VII, followed by liver biopsy. The HS grades from liver biopsy were classified as S0 (<5%), S1 (5-33%), S2 (33-66%), and S3 (>66%). For CAP, they were S0 (≤218dB/m), S1 (218-249dB/m)), S2 (250-305dB/m)), and S3 (>305dB/m)). The CAP measurements were compared with the liver biopsy results. RESULTS: Of the 150 potential donors [male, 73.3%; mean age, 30.0±7.0 years; body mass index (BMI), 24.7±3.5kg/m2], 92 (61.3%) had no or mild HS, while 58 (38.7%) and 10% had moderate to severe HS based on CAP and liver biopsy, respectively. Subjects with moderate to severe HS per CAP were mostly males (0.014), and had higher BMI (p = .006), alanine aminotransferase (ALT) (.001), gamma-glutamyl transferase (.026), and high-density lipoprotein (.008). On multivariate analysis, high ALT (OR, 1.051; 95% CI, 1.016-1.087; p = .004) was a predictor of significant HS. The sensitivity, specificity, positive and negative predictive values of CAP to detect significant HS were 93.3%, 67.4, 24.1%, and 98.9%, respectively. CONCLUSION: The high sensitivity and negative predictive values of CAP make it a good screening test to exclude significant HS in potential living liver donors which, in turn, can help avoid unnecessary liver biopsies.

Clinical Practice Guidelines for Liver Transplantation in Saudi Arabia.

The demand for liver transplantation in the Kingdom of Saudi Arabia (KSA) is associated with the country's high burden of liver disease. Trends in the epidemiology of liver transplantation indications among recipients in KSA have changed over 20 years. Non-alcoholic steatohepatitis has eclipsed the hepatitis C virus in the country due to the effective treatment strategies for HCV. Risk factors for NASH, like type 2 diabetes mellitus, obesity, and hyperlipidemia, are becoming a major concern and a leading indication for liver transplantation in the KSA. There is also a significantly increased prevalence and incidence of genetic adult familial liver diseases in KSA. New immunosuppressive agents and preservation solutions, improved surgical capabilities, and early disease recognition and management have increased the success rate of liver transplant outcome but concerns about the side effects of immunosuppressive therapy can jeopardise long-term survival outcomes. Despite this, indications for liver transplantation continue to increase, resulting in ongoing challenges to maximize the number of potential donors and reduce patient mortality rate while expecting to get transplanted. The Saudi Center of Organ Transplant is the recognized National Organ Donation Agency for transplantation, which renders important support for procurement and allocation of organs. This guidance document aims to help healthcare providers in managing patients in the liver transplant setting.

Is It Justified to Use Liver Grafts From Living Donors for Retransplant? A Single-Center Experience.

OBJECTIVES: Liver retransplant is considered the only hope for patients with irreversible graft failure after primary transplant. In most Western centers, retransplantis done mainly from deceased donors; so far, only few published studies have reported on outcomes of liver retransplant with living donors. In this study, our aim was to analyze the outcomes of living-donor liver retransplant. MATERIALS AND METHODS: Patients who underwent liver retransplant between February 2011 and February 2019 were included in the study. Preoperative, operative, and postoperative data were analyzed. Results from 2 patient groups were compared: liver retransplant with living donors and liver retransplant with deceased donors. RESULTS: Thirty-two patients underwent liver retransplant (21 adult and 11 pediatric patients). The most common indications for liver retransplant were hepatic artery thrombosis (28.5%) and primary graft nonfunction (23.8%) in adults and hepatic artery thrombosis (45.5%) and chronic rejection (36.4%) in pediatric patients. Seventeen retransplant patients (53.1%) required early retransplant (within 1 mo), mainly due to hepatic artery thrombosis (52.9%) and primary graft nonfunction (35.3%). Late retransplant was mainly due to chronic rejection (40%) and recurrence of primary disease (26.7%). Seventeen patients (53.1%) underwent living-donor retransplant, and 5 donors underwent robotic right hepatectomy. Graft and patient survival rates at 1, 3, and 5 years were 81.3% for living-donor and 51.4% for deceased-donor liver retransplant recipients (P = .08). On multivariate analyses, we observed significant differences between both groups in pretransplant Model for End-Stage Liver Disease and Pediatric End-Stage Liver Disease scores (P = .05), preoperative international normalized ratio (P = .012), and cold ischemia time (P = .046). CONCLUSIONS: The use of living donors for liver retransplant, despite its technical demand, was shown to be a safe and feasible option, especially when there is scarcity of deceased donors.

The pitfalls of endotracheal intubation beyond the fistula in babies with type C esophageal atresia.

The intraoperative management of a neonate with esophageal atresia (EA) and distal tracheoesophageal fistula (TEF) is a true anesthetic challenge. Pediatric anesthesia textbooks recommend a distal tracheal intubation beyond the fistula and spontaneous ventilation, if possible, until surgical control of the fistula is achieved to minimize gastric distention. A full-term neonate with Trisomy 21 presented with an EATEF and was transferred to the operating theater for repair after appropriate evaluation. After induction of anesthesia, a size 3.0 endotracheal tube was inserted orally with confirmation of its position by good air entry and chest movement bilaterally. After positioning for thoracotomy, the patient desaturated and became bradycardic with abdominal distention. Despite reintubation, gastric needle decompression, and bilateral pleural aspiration to exclude pneumothorax, cardiopulmonary resuscitation was unsuccessful and the child died. Autopsy revealed the endotracheal tube in the trachea with its distal end passing through a large distal TEF. Preoperative bronchoscopy may help the team to assess the size and location of the distal TEF and plan for the best anesthetic strategy. It may also be useful to confirm tube location after endotracheal intubation and intraoperatively in the event of cardiorespiratory instability.

Carotid artery angioplasty and stenting: introduction of a new technique into an established vascular surgery center.

BACKGROUND: The aim of this study was to review our initial experience with the introduction of carotid artery angioplasty and stenting as a treatment for carotid stenosis in high-risk patients and compare clinical outcomes to carotid endarterectomy patients treated over the same time period at our center. METHODS: A total of 265 carotid revascularization procedures (45 carotid artery angioplasty and stenting and 220 carotid endarterectomy) were performed over 3 years period. In the carotid artery angioplasty and stenting group, 93% were at high risk according to the current reporting standards. Death, neurological events, and restenosis rates were compared at 30 days and at most recent follow-up. RESULTS: Mean follow-up for all patients was 18 months (range 0-48 months). Carotid artery angioplasty and stenting group had higher cardiac risk than carotid endarterectomy group (13% vs 2%, P < .05). High-risk carotid lesions were present in 67% of carotid artery angioplasty and stenting patients. There was a tendency toward higher restenosis rate in carotid artery angioplasty and stenting than in carotid endarterectomy patients (35% vs 15%, P = .06). Combined stroke and death was higher in the carotid stenting group (4% and 9%) compared to the carotid endarterectomy group (0.5% and 0.5%) at 30 days and at late follow-up, respectively (P = .04 and .00). CONCLUSION: Restenosis and stroke were observed more frequently in our initial experience in patients undergoing carotid artery angioplasty and stenting compared with carotid endarterectomy patients during the same time period. These differences disappeared in high-risk patients. Further studies, to evaluate the effect of the learning curve on early results as well as follow-up for intermediate and long-term durability of carotid artery angioplasty and stenting in high-risk patients, are required.

The first two cases of living donor liver transplantation using dual grafts in Saudi Arabia.

The concept of dual-graft liver transplantation was introduced to overcome the discrepancy between liver transplantation demand and liver donation. Dual-graft transplantation also mitigates cumulative family risk by decreasing individual donor risk through minimization of the resected liver volume from each donor. Here, we describe the first two cases performed in Saudi Arabia wherein a dual-graft living donor liver transplantation was facilitated by the use of one left lobe graft and one left lateral segment in both cases. These are the first two cases of dual-graft liver transplantation reported from Saudi Arabia and the Middle East. SIMILAR CASES PUBLISHED: Nine on the same subject in other parts of the world (Korea, Japan, Germany, China, and Brazil).

Atypical Presentation of a Rare Disease: Eosinophilic Cholangitis Posing as a Cancer.

BACKGROUND A variety of benign etiologies of biliary stricture may initially be mistaken for hilar cholangiocarcinoma. Consequently, many patients undergo surgery for a benign disease that could have been treated medically. Eosinophilic cholangitis (EC) is an uncommon, benign, self-limiting disease that should be considered when approaching a case of obstructive jaundice since it causes biliary stricture formation. Transmural eosinophilic infiltration of the biliary tree is characteristic of EC. It may initially be indistinguishable from hilar cholangiocarcinoma. CASE REPORT We present a rare case of an 84-year-old male who was referred to our hospital for abdominal mass investigation with the provisional diagnosis of cholangiocarcinoma. During the workup, the index of suspicion for malignancy remained high as the typical laboratory and radiological findings for benign causes of biliary stricture were not present. Hence, the patient underwent left hepatectomy with caudate lobe resection and received a retrograde diagnosis of EC. CONCLUSIONS This case demonstrates that EC could present in the elderly with cardinal signs of cancer and absence of the typical findings of EC which was not previously reported. Since only 70% of patients present with peripheral eosinophilia, we stress on the importance of implementing diagnostic criteria for EC in the setting where peripheral eosinophilia is absent. Furthermore, this disorder has been reported to respond well to steroid therapy, hence, diagnostic criteria for EC would provide another treatment option for elderly and/or those who are not fit for surgery.

Effect of Downstaging and Bridging of Hepatocellular Carcinoma on Survival Following Liver Transplant: A Single Center Experience.

OBJECTIVES: Hepatocellular carcinoma is among the leading causes of cancer death. The Milan criteria are the first and most widely used criteria for selecting patients with hepatocellular carcinoma for a good transplant outcome. Studies have shown that patients with hepatocellular carcinoma outside the Milan criteria have good outcomes if they are successfully downstaged before transplant. We report our experience with locoregional therapy for hepatocellular carcinoma, either for bridging or for downstaging prior to transplant. MATERIALS AND METHODS: We retrospectively reviewed the electronic charts and our institutional database for adult patients diagnosed with hepatocellular carcinoma between 2001 and 2016. We recorded patient demographics, the type of transplant (living donor or deceased donor), radiologic findings, the type of locoregional intervention, and overall survival. RESULTS: A total of 642 adult liver transplants were performed during the study period (290 living donor and 352 deceased donor), of which 158 (24.6%) were conducted in patients with hepatocellular carcinoma (104 men and 54 women). Hepatocellular carcinoma was associated with hepatitis C in 80 patients (51%), hepatitis B in 44 (28%), and was cryptogenic in 13 (8%). Patients were grouped based on their radiologic staging (within Milan, within and beyond University of California, San Francisco), and subsequently described by whether they received locoregional therapy. Median survival and mortality were noted. Kaplan-Meier survival curves showed no statistically significant difference for patients within the Milan criteria, with or without locoregional therapy (P = .5). When patients within the Milan criteria were combined with patients within the University of California, San Francisco criteria, those who were downstaged from outside the latter criteria had similar survival. CONCLUSIONS: We demonstrate that carefully selected patients beyond the Milan criteria and even beyond the University of California, San Francisco criteria can be bridged and downstaged successfully for liver transplant.
