The Implication of Center Volumes in Donation After Circulatory Death for Liver Transplantation: Donor-Recipient Selection and Outcomes.

Background: The use of donation after circulatory death liver transplant (DCD LT) has increased and the outcomes have improved. There are little data concerning the details of centers' practice.

Methods: Using the United Network for Organ Sharing Standard Transplant Analysis and Research data, the centers were stratified into 4 quartiles: lowest-, low-, high-, and highest-volume quartiles.

Limited upper midline incision for major hepatectomy in adults: safety and feasibility.

Objectives: Optimal incision for major hepatectomy remains controversial. In this study, we described our experience with a limited upper midline incision (UMI) for major hepatectomy. The objective was to analyze the feasibility and safety of UMI in major hepatectomy.

Systematic review of squamous cell carcinoma of the gallbladder.

Background: Although gallbladder cancer is the most common biliary tract malignancy, squamous cell carcinoma of the gallbladder (GBSCC) is extremely uncommon, comprising approximately 1-4% of all malignant gallbladder tumors. Given its rare incidence, there are currently no established treatment guidelines for GBSCC.

Methods: We reviewed the current data available through a comprehensive search of PubMed/MEDLINE and Embase.

Two hundred and fifty-one right hepatectomies for living donation: Association between preoperative risk factors, hepatic dysfunction, and complications.

Background: Donor safety is essential in living donor liver transplantation. In this study we assessed the association among perioperative factors, liver dysfunction, and complications in 251 consecutives right hepatectomies for living donation.

Methods: Retrospectively collected data from a prospectively assembled cohort of 251 consecutive living donors who underwent right hepatectomy between 1999 and 2020 were evaluated.

Kidney transplantation using lymphocyte depleting induction and standard maintenance immunosuppression at the height of the SARS-CoV-2 pandemic in New York City: A single-center experience.

Background: Concerns have been raised regarding proceeding with kidney transplantation using standard immunosuppression in COVID-19 endemic areas.

Methods: We performed a single-center review of all adult kidney transplants performed during the COVID-19 pandemic in New York City. Patients were managed with standard immunosuppression protocols, including lymphocyte depleting induction and trough-guided tacrolimus.

Influence of patient characteristics and immunosuppressant management on mortality in kidney transplant recipients hospitalized with coronavirus disease 2019 (COVID-19).

The influence of patient characteristics and immunosuppression management on COVID-19 outcomes in kidney transplant recipients (KTRs) remains uncertain. We performed a single-center, retrospective review of all adult KTRs admitted to the hospital with confirmed COVID-19 between 03/15/2020 and 05/15/2020. Patients were followed from the date of admission up to 1 month following hospital discharge or study conclusion (06/15/2020).

Coronavirus Disease 2019 Pandemic: Early Observations in Abdominal Organ Transplantation.

The recent COVID-19 outbreak has quickly become a worldwide pandemic emergency. The course of this pandemic is still unknown, with more than 6 million cases identified and over 370 000 deaths globally as of June 1, 2020. The uncertainty and anxiety during this period will have a detrimental effect on the global health system.

Simultaneous local excision of synchronous rectal polyps by transanal endoscopic microsurgery.

Background: The approach to surgical resection of multiple rectal lesions when endoscopic polypectomy is unsuccessful has historically been radical rectal resection with total mesorectal excision. This approach is fraught with high morbidity and mortality. We explored the possibility of performing one transanal endoscopic microsurgery procedure to resect multiple synchronous rectal lesions.

Outcomes of Low-Grade Appendiceal Mucinous Neoplasms with Remote Acellular Mucinous Peritoneal Deposits.

Background: Occasionally, low-grade appendiceal mucinous neoplasms (LAMN) present with mucinous peritoneal deposits (MPD) localized to periappendiceal tissue or diffused throughout the peritoneum.

Objective: This study was aimed at evaluating the relevance of mucin cellularity for predicting outcomes of LAMN with remote MPD.

Methods: The records of patients with LAMN and remote MPD who underwent initial assessment at a comprehensive cancer center from 1990 to 2015 were reviewed, and diagnostic procedures, treatments, and outcomes were analyzed.

Laparoscopic Total Mesorectal Excision Following Transanal Endoscopic Microsurgery for Rectal Cancer.

Background: Patients' selection for transanal endoscopic microsurgery (TEM) depends on diagnostic modalities; however, there are still some limitations in the preoperative diagnosis of rectal lesions, and in some reports, up to third of the adenomas resected by TEM were found to be adenocarcinoma; therefore, salvage radical resection (RR) remains necessary for achieving oncological resection. Salvage RR may encounter some technical problems as the violation of the mesorectum and the scar formation. In this study, we aimed to report the outcome in patients undergoing salvage RR in terms of morbidity and oncological results.

The outcome of transanal endoscopic microsurgery in obese patients.

Background: The prevalence of obesity is as high as one-third of the adult population in the ultrasound. Obese patients operated for rectal cancer are less likely to undergo sphincter-preserving surgery, and have an increased morbidity and mortality. We aim to report the outcomes of transanal-endoscopic-microsurgery (TEM) in obese patients with benign and malignant neoplasms.

Five Years, Two Surgeons, and over 500 Bariatric Procedures: What Have We Learned?

Background: Bariatric surgery has become an increasingly popular method for weight loss and mitigation of co-morbidities in the obese population. Like any field, there is a desire to standardize and accelerate the postoperative period while maintaining safe outcomes.

Methods: All laparoscopic sleeve gastrectomies (LSG) and gastric bypasses (LGB) were performed over a 5-year period were logged along with several aspects of postoperative care.

Transanal Endoscopic Microsurgery Combined with Laparoscopic Colectomy for Synchronous Colorectal Tumors: A Word of Caution.

Background: The incidence of malignant synchronous colorectal tumors (SCRT) is between 2% and 5%, and the association of synchronous adenomatous polyps in colon cancer has been reported to be 15%-50%. Surgical resection is the primary treatment option for SCRT not amendable to endoscopic resection. Lesions in adjacent segments are usually treated with more extensive resection; however, there is still some controversy on how to best treat synchronous lesions in separate segments, especially when the rectum is involved.
