First Report of Two-stage Living Donor Liver Transplantation to Avoid Futility and Ensure Double Equipoise in Acute Liver Failure Complicated by Toxic Liver Syndrome.

Acute hepatic failure may occasionally be complicated by toxic liver syndrome. Emergency hepatectomy for stabilization followed by delayed graft implantation is a recognized strategy in such cases in the setting of deceased donor liver transplantation. Living donor liver transplantation adds additional complexity to this scenario as the donor liver is a directed donation and failure to stabilize the patient after emergency hepatectomy can lead to a futile live donor hepatectomy, hepar-divisum, or an orphan graft. We report a case where the two-stage strategy was utilized to circumvent this situation. A patient with toxic liver syndrome underwent emergency hepatectomy and was closely monitored in the operating theater. A live donor hepatectomy was started after the recipient demonstrated cardiovascular and neurological stabilization. Graft implantation was completed after an anhepatic period of 9.45 h. To our knowledge, this is the first reported instance of using the two-stage strategy in living-donor-liver-transplantation for toxic liver syndrome to prevent futile donor surgery and achieve double equipoise.

Protocol to ensure continued pediatric liver transplantation service during the COVID pandemic and the encouraging outcomes.

Coronavirus disease 2019 is a global pandemic, and to deal with the unexpected, enormous burden on healthcare system, liver transplantation (LT) services have been suspended in many centers. Development of robust and successful protocols in preventing the disease among the recipients, donors and healthcare workers would help in re-starting the LT programs. We adapted a protocol at our center, which is predominantly a living donor liver transplant center based in north India, and continued the service as the pandemic unfolded and peaked in India with good results and shared the experience of the same. Between March 24 and June 7, 2020, during the government-enforced public curfew-"lockdown"-7 children received LT. The protocols of infection control were drafted in our team by local customization of published guidelines. The number of pediatric LT done during the lockdown period in 2020 was similar to that done in corresponding pre-COVID period in 2019. The outcomes were of 100% survival, and none of recipients developed COVID. One potential donor was asymptomatic positive for COVID, responded well to conservative treatment, and was later accepted as a donor. LT program during the COVID pandemic can successfully function after putting in place standard protocols for infection control. These can be implemented with minimal extra involvement of healthcare infrastructure, hence without diversion of resources from COVID management. In conclusion, pediatric liver transplantation services can be continued amid COVID-19 pandemic after establishing a properly observed protocol with minimum additional resources.

Living Donor Liver Transplant in patients with Hepatorenal Syndrome without the use of Intraoperative Renal Replacement Therapy, a single-center experience.

BACKGROUND: Continuous Renal Replacement Therapy (CRRT) is often used to support the intraoperative course during liver transplantation (LT) for patients with HRS. However, the use of intraoperative CRRT (IOCRRT) is not without its problems. Living donor liver transplantation (LDLT) is a planned operation and is possible without IOCRRT as the recipient can be optimized. AIM: To study the peritransplant outcomes of patients with CLD and HRS undergoing LT without IOCRRT. METHODS: Analysis of LT program database for perioperative outcomes in patients with HRS from Feb 2017 to Dec 2018. RESULTS: 87/363 (23.9%) adult LDLT patients had HRS, of whom 31 (35.6%) did not respond (NR) to standard medical therapy (SMT) prior to LT. Modified perioperative protocol enabled the NR patients (who were sicker and in persistent renal failure) to undergo LT without IOCRRT. Postoperative renal dysfunction was similar (2 in NR and 2 in R) at 1 year. Post-LT survival was also not different at one month (83.87% in NR and 87.5% in R [p = .640]) and at 1 year (77% in NR vs 80.4% in non-responders [p = .709]). CONCLUSION: IOCRRT can be avoided in HRS patients undergoing LDLT without compromising their outcomes (post-LT survival and RD), even in patients who have not responded to SMT, preoperatively.

Outcome of Pediatric Liver Transplants in Patients With Less Than 10 kg of Body Weight Is Not Worse.

OBJECTIVES: Liver transplant in pediatric patients with body weight < 10 kg poses a challenge to the entire liver transplant team. Many reports have considered 10 kg to be a cutoff pointfor body weightforfavorable posttransplant outcomes. With evolving surgical techniques and postoperative management, there is potential to improve outcomes in this subset of recipients. We compared the outcomes in pediatric patients with body weight < 10 kg with those > 10 kg; also, we studied the factors of influence. MATERIALS AND METHODS: We performed a retrospective analysis to evaluate the outcomes of liver transplants in pediatric patients with < 10 kg body weight. The cohort consisted of 90 children subdivided into the following 2 subgroups: group A (n = 35) with > 10 kg body weight at liver transplant and group B (n = 55) with < 10 kg body weight at liver transplant. We compared the following pretransplant characteristics between the groups: graft weight, graft-to-recipient weightratio, cold ischemia time, warm ischemia times, and liver transplant outcomes. RESULTS: Pediatric End-stage Liver Disease score was significantly higher in group B (score of 24) versus group A (score of 18). Group B had significantly higher graft-to-recipient weight ratio (2.8 in group B vs 1.7 in group A). Graft function showed no significant difference between the 2 groups. Portal vein thrombosis was seen only in group B, whereas biliary leaks were observed among 5 patients in group B and 1 patientin group A. Patient survivalrate was higherin group B (86%) than in group A (77%). CONCLUSIONS: Pediatric patients weighing < 10 kg have similarif not better survivalrates after liver transplant compared with patients > 10 kg. Advancements in surgical techniques and a careful monitoring for complications and timely intervention are important to facilitate these outcomes.

External validation and comparison of the original, alternative and updated-alternative fistula risk scores for the prediction of postoperative pancreatic fistula after pancreatoduodenectomy.

BACKGROUND: Many postoperative pancreatic fistula (POPF) predictions models were developed and validated in western populations. Direct use of these models in the large Indian/Asian population, however, requires proper validation. OBJECTIVE: To validate the original, alternative and updated alternative fistula risk score (FRS) models. METHODS: A validation study was performed in consecutive patients undergoing pancreatoduodenectomy (PD) from January 2011 to March 2018. The area under the receiver operating curve (ROC) and calibration plots were used to assess the performance of original-FRS (o-FRS), alternative FRS (a-FRS) and updated alternative FRS (ua-FRS) models. RESULTS: This cohort consisted of 825 patients of which 66% were males with a median age of 55 years and mean body mass index of 22.6. The majority of tumors (61.8%) were of periampullary origin. Clinically relevant POPF was observed in 16.8% patients. Area under curve (AUC) of ROC for the o-FRS was 0.65, 0.69 for a-FRS and 0.70 for ua-FRS, respectively (p = 0.006). CONCLUSIONS: In this large Indian cohort of predominantly periampullary tumors, the ua-FRS performed better than the a-FRS and o-FRS, although differences were small. Since the AUC value of the ua-FRS is at the accepted threshold there might be room for improvement for a FRS.

Hepatocellular carcinoma metastasis to the buccal mucosa masquerading as oral cavity malignancy: Case report of a rare entity.

Hepatocellular carcinoma, a disease of the developing world, is known to present with extrahepatic metastases. Most common site being the lungs, it is not uncommon for metastases to present at unusual sites like the rectum, spleen and the diaphragm, among others. Metastases to the oral cavity is rare, with the most common primaries being lung, breast and the kidney. Metastases of a hepatocellular carcinoma to the oral cavity is a rare entity with extremely limited data in literature. We present one such unique case of oral cavity metastases from a hepatocellular carcinoma who presented to the Division of Head and Neck Oncology services of our hospital with a large oral cavity lesion, on subsequent workup of which, a hepatocellular carcinoma was identified. Awareness of this possibility can aid in accurate diagnosis and early management of a condition associated with an advanced stage at presentation and poorer prognosis.

Pelvic Exenteration with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy (CRS + HIPEC) for Rectal Cancer-Case Series with Review of Literature.

Incidence of synchronous peritoneal metastases (PM) in colorectal cancer is approximately 5%, with another 5% of the patients develop metachronous PM. Colorectal PM has been hypothesized to be a loco-regional disease rather than a systemic spread, and cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has been considered as a viable treatment option. Pelvic exenteration is an established treatment option for locally advanced rectal cancer, but it is associated with significant morbidity. However, there are no studies evaluating the role of such procedure probably because the majority consider it as an exclusion criterion. Here, we present our experience with three cases of locally advanced rectal cancer with PM, treated successfully with pelvic exenteration and CRS-HIPEC.
