Abstract
BACKGROUND Hepatic artery infusion pump (HAIP) with floxuridine/dexamethasone and systemic chemotherapy is an established treatment regimen, which had been reported about converting 47% of patients with stage 4 colorectal liver metastasis from unresectable to resectable.1,2 To this effect, HAIP chemotherapy contributes to prolonged survival of many patients, which otherwise may not have other treatment options. Biliary sclerosis, however, is a known complication of the HAIP treatment, which occurs in approximately 5.5% of patients receiving this modality as an adjuvant therapy after hepatectomy and in 2% of patients receiving HAIP treatment for unresectable disease.3 While biliary sclerosis diffusely affects the perihilar and intrahepatic biliary tree, a dominant stricture maybe found in select cases, which gives an opportunity for a local surgical treatment after failure of endoscopic stenting/dilations. While the use of minimally invasive approach to biliary surgery is gradually increasing,4 there have been no descriptions of its application in this scenario. In this video, we demonstrate the use of minimally invasive robotic technique for biliary stricturoplasty and Roux-en-Y (RY) hepaticojejunostomy to treat persistent right hepatic duct stricture after HAIP chemotherapy. PATIENT A 68-year-old woman with history of multifocal bilobar stage 4 colorectal liver metastasis presented to our office with obstructive jaundice and recurrent cholangitis that required nine endoscopic retrograde cholangiopancreatographies (ERCPs) and a placement of internal-external percutaneous transhepatic biliary drain (PTBD) by interventional radiology within the past 2 years. Her past surgical history was consistent with laparoscopic right hemicolectomy 3 years prior, followed by a left lateral sectorectomy with placement of an HAIP for adjuvant treatment. The patient had more than ten metastatic liver lesions within the right and left lobe, ranging from 2 to 3 cm in size at the time of HAIP placement. The patient had a histologically normal background liver parenchyma before the HAIP chemotherapy treatment. The patient did not have any history of alcohol use, diabetes mellitus, metabolic syndrome, nonalcoholic steatohepatitis, or other underlying intrinsic liver disorders, which are known to contribute to the development of hepatic fibrosis. Despite a radiologically disease-free status, the patient started to have episodes of acute cholangitis 1 year after the placement of HAIP that required multiple admissions to a local hospital. The HAIP was subsequently removed once the diagnosis of biliary sclerosis was made despite dose reductions and treatment with intrahepatic dexamethasone for almost 1 year. In addition to this finding, the known liver metastases have shown complete radiological resolution. Therefore further treatment with HAIP was deemed unnecessary, and pump removal was undertaken. Magnetic resonance imaging showed a dominant stricture at the junction of the right anterior and right posterior sectoral hepatic duct. The location of the dominant stricture was confirmed by an ERCP and cholangioscopy. Absence of neoplasia was confirmed with multiple cholangioscopic biopsies. Multiple endoscopic and percutaneous attempts with stent placement failed to dilate the area of stricture. Postprocedural cholangiographies showed a persistent significant narrowing, which led to multiple recurrent obstructive jaundice and severe cholangitis. While the use of surgical approach is rarely needed in the treatment of biliary sclerosis, a decision was made after extensive multidisciplinary discussions to perform a robotic stricturoplasty and RY hepaticojejunostomy with preservation of the native common bile duct. TECHNIQUE The operation began with a laparoscopic adhesiolysis to allow for identification of HAIP tubing (which was later removed) and placement of robotic ports. A peripheral liver biopsy was obtained to evaluate the degree of hepatic parenchymal fibrosis. Porta hepatic area was carefully exposed without causing an inadvertent injury to the surrounding hollow organs. Biopsy of perihepatic soft tissues was taken as appropriate to rule out any extrahepatic disease. The common bile duct and common hepatic duct with ERCP stents within it were identified with the use of ultrasonography. Anterior wall of the common hepatic duct was then opened, exposing the two plastic stents. Cephalad extension of the choledochotomy was made toward the biliary bifurcation and the right hepatic duct. The distal common bile duct was preserved for future endoscopic access to the biliary tree. After lowering the right-sided hilar plate, dense fibrosis around the right hepatic duct was divided sharply with robotic scissors, achieving a mechanical release of the dominant stricture. An intraoperative cholangioscopy was performed to confirm adequate openings of the right hepatic duct secondary and tertiary radicles, as well as patency of the left hepatic duct. A 4-Fr Fogarty catheter was used to sweep the potential biliary debris from within the right and left hepatic lobe. Finally, a confirmatory choledochoscopy was performed to ensure patency and clearance of the right-sided intrahepatic biliary ducts and the left hepatic duct before fashioning the hepaticojejunostomy. A 40-cm antecolic roux limb was next prepared for the RY hepaticojejunostomy. A side-to-side double staple technique was utilized to create the jejunojejunostomy. The common enterotomy was closed in a running watertight fashion. Once the roux limb was transposed to the porta hepatic in a tension-free manner, a side-to-side hepaticojejunostomy was constructed in a running fashion by using absorbable barbed sutures. The index suture was placed at 9 o'clock location, and the posterior wall of the anastomosis was run toward 3 o'clock location. This stabilized the roux limb to the bile duct. The anterior wall of the anastomosis was next fashioned by using a running technique from both corners of the anastomosis toward the middle (12 o'clock), where both sutures were tied together. This completed a wide side-to-side hepaticojejunostomy anastomosis encompassing the upper common hepatic duct, biliary bifurcation, and the right hepatic duct. A closed suction drain was placed before closing.5 RESULTS: The operative time was approximately 4 hr with 60 ml of blood loss. The postoperative course was uneventful. The patient was discharged home on postoperative Day 5 after removal of the closed suction drain, confirming the absence of bile leak. The patient had developed periportal/periductal fibrosis, cholestasis, and moderate-severe parenchymal fibrosis (F3-F4) based on liver biopsy, often seen in patients treated with a long course of floxuridine HAIP chemotherapy. The patient is clinically doing well at 1 year outpatient follow-up without any evidence of recurrent cholangitis at the time of this manuscript preparation. CONCLUSIONS Robotic biliary stricturoplasty with RY hepaticojejunostomy for treatment of biliary sclerosis after HAIP chemotherapy is safe and feasible. Appropriate experience in minimally invasive hepatobiliary surgery is necessary to achieve this goal.

Abstract
The distal bile duct was isolated and transected with a frozen section examination confirming the absence of malignancy. Attention was then shifted to constructing a 60 cm Roux limb by first identifying and transecting the proximal jejunum 40 cm from the ligamentum of Treitz. A side-to-side stapled jejunojejunostomy anastomosis was completed. The Roux limb was transposed toward the porta hepatis through an antecolic approach.

Abstract
INTRODUCTION Despite numerous benefits offered, robotic procedures take longer than "open" procedures. With the intent to reduce operative duration, we examined the degree each operative step contributes to operative duration in robotic pancreaticoduodenectomy. MATERIALS AND METHODS With IRB approval, we prospectively followed 88 patients to determine the duration of robotic pancreaticoduodenectomy, and the duration of 12 key steps. Each operative step was regressed against the operation date, from most distant to most recent operation date. Data are presented as median (mean ± SD) for illustrative purposes. RESULTS Patients were 73 (71 ± 10.2) years old; 53% were men. Total time patient spent in the operating room was 471 (488 ± 93.3) minutes. Total operative time was 399 (421 ± 90.7) minutes. Total console time was 293 (297 ± 68.0) minutes. The 3 longest portions of the operation were (1) mobilization of the specimen and specimen extraction; (2) construction of the duodenojejunostomy; and (3) closure. CONCLUSION A third of the operative time is spent off the console. Over half of the steps required more than 20 minutes each to complete. Since robotic operations are associated with shorter LOS and without increased complication rates relative to "open" operations, salutary benefit can be gained by decreasing operative times of robotic procedures. Operative duration is an important metric that needs to be addressed. We need to target the most time-consuming steps, and break them into smaller pieces, to reach optimal efficiency and provide the benefits of decreased operative duration to the patients, hospitals, and providers.

Abstract
BACKGROUND As the first comprehensive investigation into hospital readmissions following robotic hepatectomy for neoplastic disease, this study aims to fill a critical knowledge gap by evaluating risk factors associated with readmission and their impact on survival and the financial burden. METHODS The study analyzed a database of robotic hepatectomy patients, comparing readmitted and non-readmitted individuals post-operatively using 1:1 propensity score matching. Statistical methods included Chi-square, Mann-Whitney U, T-test, binomial logistic regression, and Kaplan-Meier analysis. RESULTS Among 244 patients, 44 were readmitted within 90 days. Risk factors included hypertension (p = 0.01), increased Child-Pugh score (p < 0.01), and R1 margin status (p = 0.05). Neoadjuvant chemotherapy correlated with lower readmission risk (p = 0.045). Readmissions didn't significantly impact five-year survival (p = 0.42) but increased fixed indirect hospital costs (p < 0.01). CONCLUSIONS Readmission post-robotic hepatectomy correlates with hypertension, higher Child-Pugh scores, and R1 margins. The use of neoadjuvant chemotherapy was associated with a lower admission rate due to less diffuse liver disease in these patients. While not affecting survival, readmissions elevate healthcare costs.

Abstract
Esophageal resection for the treatment of esophageal cancer generally entails high rates of morbidity and mortality. Patients with a smoking history have increased post-operative complications following esophagectomy. This study was undertaken to determine how smoking or a history of smoking can affect perioperative outcomes and morbidity following robotic transhiatal esophagectomy. 75 patients were prospectively followed and divided; 44 patients actively smoking or with a history of significant smoking were classified as 'smokers', while the other 31 patients were classified as 'non-smokers'. Significance was determined at a p-value of ≤ 0.05 and data are presented as median (mean ± SD). 'Smokers' averaged 70(70 ± 7.8) years, 89% male, with 82% undergoing neoadjuvant therapy. 'Nonsmokers' averaged 68(69 ± 7.8) years, 74% male, and 74% receiving neoadjuvant therapy. BMI and ASA class showed no significant difference between the cohorts. 'Smokers' had an operative time of 341(343 ± 91.0) minutes and a blood loss of 150(191 ± 140.0) mL; 'nonsmokers' had 291(298 ± 65.9) minutes and 100(140 ± 120.9) mL, respectively (p = 0.02 for operative time). Tumor size and AJCC staging were similar for both cohorts. No significant differences were noted in postoperative complications, Clavien-Dindo score ≥ III, in-hospital mortality, length of stay, or 30-day readmissions. Survival rates were comparable. Hospital costs for 'smokers' were $33,131(41,091 ± 23,465.17) and $34,896 (62,154 ± 65,839.53) for 'nonsmokers' (p = 0.05). Profit/loss was $-23,155 (- 15,137 ± 35,819.29) for smokers and $-23,720 (- 16,716 ± 50,864.64) for nonsmokers. Current or past 'smokers' had longer operative times and lower costs following robotic transhiatal esophagectomy, with no significant difference in postoperative complications or survival compared to 'non-smokers'.

Abstract
This study was undertaken to observe the effect of body mass index (BMI) on perioperative outcomes and survival when comparing robotic vs 'open' pancreaticoduodenectomy. With IRB approval, we prospectively followed 505 consecutive patients who underwent either robotic or 'open' pancreaticoduodenectomy from 2012 to 2021. For illustrative purposes, patients were separated based on the Center for Disease Control and Prevention BMI table but regression analysis was utilized to identify significant relationships involving BMI. Data are presented as median (mean ± SD). Significance was determined at p ≤ 0.05. 205 and 300 patients underwent 'open' and robotic pancreaticoduodenectomy, respectively. Neither sex nor age correlated with BMI in patients undergoing 'open' nor robotic operation. Operative duration correlated with increasing BMI in each operational approach, which was statistically significant for those receiving the 'open' operation (p = 0.02). There were statistically significantly fewer lymph nodes harvested with rising BMI in patients that had an 'open' operation (p = 0.01), but no such difference was found in patients undergoing the robotic approach. Length of stay (LOS) and in-hospital mortality were statistically significantly associated with rising BMI when an 'open' operation was undertaken (p = 0.02 and p = 0.0002, respectively) but not when the robotic platform was utilized. Patients with higher BMI had significantly longer operative duration, smaller lymph node harvest, greater LOS, and increased in-hospital mortality rate when undergoing 'open' pancreaticoduodenectomy, but not robotic pancreaticoduodenectomy. Thus, the robotic platform may attenuate the increased technical and oncologic difficulties associated with a greater BMI in patients undergoing pancreaticoduodenectomy.

Abstract
Bile duct injury is a rare complication in the modern era of minimally invasive laparoscopic and robotic surgery; however, it can lead to serious short- and long-term consequences. Repair of bile duct injury with Roux-en-Y hepaticojejunostomy is a technically complex operation, especially when undertaken laparoscopically. Newer robotic technology improves surgeon's dexterity for fine suturing tasks such as in creating a delicate hepaticojejunostomy, which overcomes technical limitations of conventional laparoscopic approach. As surgeons accumulate more experience in minimally invasive bile duct surgery for benign and malignant diseases, the accepted surgical approaches gradually transition from open to robotic technique. In this video, we describe our robotic technique for delayed repair of an E2 bile duct injury.

Abstract
Cholecystitis is a common diagnosis which requires management by general surgeons. Morbidity from cholecystitis is often life-threatening, especially in patients with underlying liver cirrhosis or other medical comorbidities. Diagnosis and management of this disease can vary among providers and hospitals. The decision to utilize a radiological or endoscopic temporizing maneuver in severe acute cholecystitis and the timing of later definitive cholecystectomy are relevant points of discussion within general surgery societies. In the last 5 years, the use of intraoperative ductal imaging by conventional vs fluorescence cholangiography had gained significant interest due to the widespread availability of indocyanine green. Finally, the operative strategies and how to manage intra-/postoperative complications are very important to optimizing patient outcomes. In this review paper, we discuss all treatment aspects of cholecystitis and provide updates in its management.

Abstract
INTRODUCTION Minimally invasive resection for perihilar cholangiocarcinoma is an emerging technique that requires both mastery in minimally invasive liver resection and biliary reconstruction. Due to technical difficulties in biliovascular dissection, radical portal lymphadenectomy and the need for fine suturing during bilioenteric anastomosis, this type of resection is generally not performed laparoscopically, even at high-volume, liver-surgery centers.1-3 In modern literature, a detailed, operative description of robotic technique for this operation with outcome data is lacking. This video article demonstrates a pure robotic Klatskin Type 3A resection with clinical outcomes of our initial series. VIDEO A 77-year-old man presented with jaundice and findings of bilateral, intrahepatic, ductal dilation (Right > Left). Radiological imaging showed a type 3A Klatskin tumor with associated thrombosis of the right, anterior portal vein. A further endoscopic evaluation with cholangioscopy confirmed a high-grade Bismuth 3A biliary malignant stricture. Endoscopic drainage was achieved with placement of two, 7-French, 15-cm, plastic, endobiliary stents. A 3-D anatomical liver reconstruction showed a 2-cm mass located in the area of right, anterior, sectoral, Glissonean pedicle with standardized, future, liver-remnant (left hepatic lobe) volume of 50%. The patient was placed supine on the operating table. General endotracheal anesthesia was administered. After exclusion of metastatic peritoneal disease with diagnostic laparoscopy, cholecystectomy and systematic radical portal lymphadenectomy were first completed with a goal to obtain more than six lymph nodes. After appropriate portal lymphadenectomy, the common bile duct was isolated and transected at the level of pancreatic head. The plastic, endobiliary stents were removed, and a distal common bile duct margin was sent for a frozen-section examination to rule out distal extension of the cholangiocarcinoma. A small, accessory, right, hepatic artery lateral to the main portal vein was ligated with locking clips and removed together with the adjacent nodes and lymphatic bearing tissues. The intrapancreatic portion of the distal common bile duct was suture closed once the distal common bile duct margin was confirmed to be negative for neoplasia by the frozen-section examination. The proximal bile-duct dissection commenced cephalad toward the hilar bifurcation. Once the biliary bifurcation has been adequately dissected and detached from the hilar plate, the distal, left, hepatic duct was then transected near the base of the umbilical fissure to gain an R-0 resection margin. A second frozen-section specimen was obtained from the left, hepatic duct cut edge to ensure an absence of infiltrating tumor cells on the future, bile-duct remnant side. Division of short, hepatic veins off the inferior vena cava (IVC) were next completed. Once the line of hepatic-parenchymal transection was confirmed by using indocyanine green administration, the right hepatic artery and portal vein were ligated and clipped. The liver, parenchymal transection began with a crush-clamp technique utilizing robotic, fenestrated bipolar forceps and a vessel-sealing device. Preservation of the middle hepatic vein is always the preferred technique to avoid congestion of the left medial sector of the liver. The entire right hepatic lobe and the caudate lobe were removed en bloc. A large, Makuuchi ligament was isolated and divided by using a robotic, vascular-load stapler once the liver is open-booked. Finally, the root of the right hepatic vein was exposed and transected flush to the IVC by using another load of robotic vascular stapler. The biliary reconstruction then began by creating a 60-cm, roux limb for a hepaticojejunostomy bilioenteric anastomosis. A side-to-side, stapled jejunojejunostomy was created by using two applications for robotic 45-mm, blue load staplers. The common enterotomy was closed with running barbed sutures. The roux limb was then transposed retrocolically toward the porta hepatis. A single end-to-side hepaticojejunostomy anastomosis was created with running absorbable 4-0 barbed sutures. Finally, a closed suction abdominal drain was placed before closing. RESULTS The operative time was approximately 8 hours with 150 ml of blood loss. The postoperative course was unremarkable. The final pathology report confirmed a moderately differentiated perihilar cholangiocarcinoma with negative resection margins. Ten lymph nodes were harvested. No nodal metastasis or lymphovascular invasion was found. Since 2021, we have undertaken robotic resection of Klatskin 3A tumor in four patients with a median age of 70 years. All patients presented with jaundice, and they mainly underwent preoperative biliary drainage using ERCP. The median operative duration was 508 minutes with estimated blood loss of 150 ml. R-0 resection margins were obtained in all patients. One patient suffered from postoperative complications requiring treatment of line sepsis using intravenous antibiotics. We did not find a 90-day mortality in this series. At a median follow-up period of 15 months, all of the patients were alive without any evidence of disease recurrence. CONCLUSIONS Robotic resection of Type 3A Klatskin tumor is safe and feasible with appropriate experience in robotic hepatobiliary surgery, as demonstrated in this video article.

Abstract
BACKGROUND Application of robotic platform for perihilar cholangiocarcinoma is an emerging technique requiring expertise in both minimally invasive hepatic resection and biliary reconstruction. Due to oncological principles of trying to achieve tumor-free margins during cholangiocarcinoma operation, surgeons often find multiple sectoral bile ducts above the hilar plate that need to be reconstructed. Creating multiple oligomilimeter hepaticojejunostomy anastomoses is not only technically very challenging but also associated with an increased risk for postoperative bile leak and subsequent anastomotic stricture mandating reinterventions. METHODS Technical maneuvers to reduce the number of biliary anastomosis had been previously described in open surgical literature. Minimally invasive technique such as simple unification ductoplasty, however, has not been described laparoscopically or robotically. RESULTS We demonstrated a successful unification ductoplasty during a robotic type 3B Klatskin tumor resection according to Bismuth-Corlette classification. Creation of multiple anastomoses in this type of operation was able to be avoided. CONCLUSION Robotic platform facilitates ductoplasty for biliary reconstruction during Klatskin tumor resection.

Abstract
Hepatocellular adenomas are benign liver tumors, more frequently seen in young women with a history of long-standing use of estrogenic hormonal contraception. An acute rupture of these adenomas can be the first sign of symptoms; however, they can be life-threatening. The definitive management of hepatic adenoma is liver resection for those larger than 4 cm as this cutoff size is known to be associated with an exponential risk of harboring malignancy and an increased risk for intratumor bleeding. Once intratumor hemorrhage occurs however, the management of hepatic adenoma becomes much more timely critical. In this study, we describe the use of robotic liver resection for the management of hemorrhagic hepatocellular adenoma in a semi-acute setting. We also include a series of robotic hepatic adenoma resection completed in our hepatobiliary program since 2016, which demonstrated the safety, feasibility, and reproducibility of robotic technique in treating hepatic adenoma.

Abstract
In the past decade, precision hepatectomy which requires the understanding of segmental and subsegmental liver anatomy has gained popularity due to its parenchymal-sparing benefits. The importance of this concept has led liver surgeons to a consensus conference and its guideline in regards to precision anatomy in minimally invasive liver resection, held in Tokyo in 2020. A precise control of the sectoral hepatic artery and portal vein allows for a bloodless liver resection, without the use of Pringle maneuver. In the literature, technical description of the right anterior portal pedicle dissection during minimally invasive robotic liver surgery is limited. In this study, we therefore demonstrate such a technique using fluorescence guidance during robotic segment 8 superior liver resection.

Abstract
BACKGROUND Identification of resections with high risk of intraoperative complications is critical in guiding case selection for minimally invasive liver surgery. Several Japanese and European difficulty scoring systems have been proposed for laparoscopic liver surgery. However, the applicability of these systems for robotic liver resections has not been fully investigated. This study considers the Southampton system and examines its validity when applied to robotic hepatectomies. METHODS We undertook a retrospective review of 372 patients who underwent robotic hepatectomies for various indications between 2013 and 2022. Of these patients, 63 operations were classified as low risk, 91 as moderate risk, 198 as high risk and 20 as extremely high risk based on Southampton criteria. Patient outcomes were compared by utilizing an ANOVA of repeated measures. Data are presented as median (mean ± SD). RESULTS The Southampton difficulty scoring system was a strong predictor of intraoperative variables including tumor size, operative duration, estimated blood loss (EBL), and incidence of major vs minor resection (all P < .0001). In contrast, the Southampton system was a weaker predictor of postoperative outcomes including 30-day mortality (P = .15), length of stay (P = .13), and readmissions within 30 days (P = .38). CONCLUSION The Southampton difficulty scoring system is a valid system for classifying robotic liver resections and is a strong predictor of intraoperative outcomes. However, the system was found to be a weaker predictor of postoperative outcomes. This finding may suggest the need for proposal of a new difficulty scoring system for robotic hepatectomies.

Abstract
BACKGROUND The Institut Mutualiste Montsouris (IMM) classification system is one of several widely accepted difficulty scoring systems for laparoscopic liver resections. Nothing is yet known about the applicability of this system for robotic liver resections. METHODS We conducted a retrospective review of 359 patients undergoing robotic hepatectomies between 2016 and 2022. Resections were classified into low, intermediate, and high difficulty level. Data were analyzed utilizing ANOVA of repeated measures, 3 x 2 contingency tables, and area under the receiving operating characteristic (AUROC) curves. Data are presented as median (mean ± SD). RESULTS Of the 359 patients, 117 were classified as low-difficulty level, 92 as intermediate, and 150 as high. The IMM system correlates well with tumor size (p = 0.002). The IMM system was a strong predictor of intraoperative outcomes including operative duration (p<0.001) and estimated blood loss (EBL) (p<0.001). The IMM system also showed a strong calibration for predicting an open conversion (AUC=0.705) and intraoperative complications (AUC=0.79). In contrast, the IMM system was a poor predictor of postoperative complications, mortality, and readmission. CONCLUSION The IMM system provides a strong correlation with intraoperative, but not postoperative outcomes. A dedicated difficulty scoring system should be developed for robotic hepatectomy.

Abstract
INTRODUCTION The detrimental effects that smoking has on patient health and postoperative morbidity are well documented. However, literature on the impact that smoking history has on robotic surgery, specifically robotic hepatectomy, is scarce. This study was undertaken to determine whether smoking history impacts the postoperative course of patients undergoing robotic hepatectomy. METHODS We prospectively followed 353 patients that underwent robotic hepatectomy. 125 patients had an apposite history of smoking (ie, smokers) and 228 patients were classified as non-smokers. Data were presented as median (mean ± SD). Patients were then propensity-score matched based on patient and tumor characteristics. RESULTS Prior to the matching, the MELD score and cirrhosis status in patients who smoke were found to be significantly higher when compared to those who do not (mean MELD score 9 vs 8 and cirrhosis in 25% vs 13% of patients, respectively). Both smokers and non-smokers have similar BMIs, number of previous abdominal operations, ASA physical status classifications, and Child-Pugh scores. Six percent smokers vs one percent non-smokers experienced pulmonary complications (pneumonia, pneumothorax, and COPD exacerbation) (P = .02). No differences were found for postoperative complications of Clavien-Dindo score ≥ III, 30-day mortality, or 30-day readmissions. After the matching, no differences were found between the smokers and the non-smokers. CONCLUSION After a propensity-score match analysis, smoking did not appear to negatively affect the intra- and postoperative outcomes after robotic liver resections. We believe that the robotic approach as the most modern minimally invasive technique in liver resection may have the potential to mitigate the known adverse effects of smoking.

Abstract
Precise regulation of transcription in gene expression is critical for all aspects of normal organism form, fitness, and function and even minor alterations in the level, location, and timing of gene expression can result in phenotypic variation within and between species including evolutionary innovations and human disease states. Eukaryotic transcription is regulated by a complex interplay of multiple factors working both at a physical and molecular levels influencing this process. In Saccharomyces cerevisiae, the TF with the greatest number of putative regulatory targets is the essential gene Repressor Activator Protein 1 (RAP1). While much is known about the roles of Rap1 in gene regulation and numerous cellular processes, the response of Rap1 target genes to systematic titration of RAP1 expression level remains unknown. To fill this knowledge gap, we used a strain with a tetracycline-titratable promoter replacing wild-type regulatory sequences of RAP1 to systematically reduce the expression level of RAP1 and followed this with RNA sequencing (RNA-seq) to measure genome-wide gene expression responses. Previous research indicated that Rap1 plays a significant regulatory role in particular groups of genes including telomere-proximal genes, homothallic mating (HM) loci, glycolytic genes, DNA repair genes, and ribosomal protein genes; therefore, we focused our analyses on these groups and downstream targets to determine how they respond to reductions in RAP1 expression level. Overall, despite being known as both an activator and as a repressor of its target genes, we found that Rap1 acts as an activator for more target genes than as a repressor. Additionally, we found that Rap1 functions as an activator of ribosomal protein genes and a repressor of the silent mating locus genes consistent with predictions from the literature. Unexpectedly, we found that Rap1 functions as a repressor of glycolytic enzyme genes contrary to prior reports of it having the opposite effect. We also compared the expression of RAP1 to five different genes related to DNA repair pathway and found that decreasing RAP1 downregulated four of those five genes. Finally, we found no effect of RAP1 depletion on telomere-proximal genes despite its functioning to silence telomeric repeat-containing RNAs. Together our results enrich our understanding of this important transcriptional regulator. The graphical abstract is provided as a supplementary fig. (S-Fig 1).

Abstract
BACKGROUND Metabolic syndrome is a known risk factor for postoperative complications after general surgical procedures. Literature analyzing perioperative outcomes of patients with metabolic syndrome undergoing a minimally invasive hepatectomy is limited. We sought to investigate if metabolic syndrome significantly impacts the perioperative course and outcomes of patients undergoing robotic hepatectomy. METHODS With IRB, we prospectively followed patients who underwent robotic hepatectomy from 2016 through 2020. A 1:1 propensity score-matched (PSM) analysis was applied to patients with and without metabolic syndrome. Demographic and clinical data were analyzed for those cohorts before and after PSM. Metabolic syndrome was defined as BMI ≥ 28.8 kg/m2, diabetes, and hypertension. RESULTS A total of 272 patients underwent robotic hepatectomy, 39 (14%) of whom had metabolic syndrome. After performing PSM, we ended up with 74 patients, 37 in each cohort, 28% of them had liver cirrhosis. Patients with metabolic syndrome had higher BMI (34 ± 5.6 vs. 28 ± 5.9 kg/m2, p < 0.001) and MELD scores (10 ± 4.5 vs. 8 ± 3.2, p < 0.001) compared to patients without metabolic syndrome. Additionally, patients with metabolic syndrome had an increased incidence of liver cirrhosis (33% vs. 9%, p = 0.0002). Following PSM, BMI (34 ± 5.7 vs. 26 ± 4.4 kg/m2, p < 0.001) was the only preoperative variables associated with metabolic syndrome. There were no statistical differences before and after PSM between patients with and without metabolic syndrome in terms of intraoperative metrics including operative time, blood loss, conversion to 'open,' and intraoperative complications. All postoperative outcomes metrics before and after PSM did not correlate with the presence or absence of metabolic syndrome. CONCLUSIONS Metabolic syndrome had no impact on intra- or postoperative metrics, complications, or outcomes after robotic hepatectomy. We believe that the robotic approach may mitigate the adverse effects of metabolic syndrome for patients undergoing robotic hepatectomy.

Abstract
Background and Objectives Obesity has increased over the past decade, yet the correlation among body mass index (BMI), surgical outcomes, and the robotic platform are not well established. This study was undertaken to measure the impact of elevated BMI on outcomes after robotic distal pancreatectomy and splenectomy. Methods We prospectively followed patients who underwent robotic distal pancreatectomy and splenectomy. Regression analysis was utilized to identify significant relationships with BMI. For illustrative purposes, the data are presented as median (mean ± SD). Significance was determined at p ≤ 0.05. Results A total of 122 patients underwent robotic distal pancreatectomy and splenectomy. Median age was 68 (64 ± 13.3), 52% were women, and BMI was 28 (29 ± 6.1) kg/m2. One patient was underweight (< 18.5 kg/m2), 31 had normal weight (18.5-24.9 kg/m2), 43 were overweight (25-29.9 kg/m2), and 47 were obese (≥ 30 kg/m2). BMI was inversely correlated with age (p = 0.05) but there was no correlation with sex (p = 0.72). There were no statistically significant relationships between BMI and operative duration (p = 0.36), estimated blood loss (p = 0.42), intraoperative complications (p = 0.64), and conversion to open approach (p = 0.74). Major morbidity (p = 0.47), clinically relevant postoperative pancreatic fistula (p = 0.45), length of stay (p = 0.71), lymph nodes harvested (p = 0.79), tumor size (p = 0.26), and 30-day mortality (p = 0.31) were related to BMI. Conclusion BMI has no significant effect on patients undergoing robotic distal pancreatectomy and splenectomy. BMI greater than 30 kg/m2 should not defer proceeding with robotic distal pancreatectomy with splenectomy. Limited empirical evidence exists in the literature regarding patients with a BMI greater than 30 kg/m2, and thus any proposed operative intervention should invoke sufficient planning and preparation.

Abstract
Minimally Invasive bile duct repair is an emerging modern technique in hepatobiliary surgery. Conventional laparoscopic technique had been sporadically reported by high volume surgeons as an alternative to open operation, however, the majority of those repairs were undertaken for biliary injury below the biliary bifurcation. Roux-en-Y Hepaticojejunostomy below the biliary bifurcation is technically much simpler to complete when compared to that above the hilar plate (high bile duct injury). The risk of long-term anastomotic stricture is also higher as bile duct caliber decreases. This is anatomically inherent as we travel further cranial beyond the hilar plate. In this multimedia article, we describe our minimally invasive technique for high bile duct injury repair using robotic technology.

Abstract
Liver resection for stage 4 colorectal cancer with liver metastasis is the standard of care, in combination with systemic chemotherapy. R-0 complete resection for colorectal liver metastasis is a curative-intent operation, which is considered the only chance for cure in this disease. The location and proximity of the tumor to major intrahepatic vessels such as hepatic and portal vein determine technical difficulty. Tumors located in the posterosuperior segments of the liver (segments 7 and 8) are technically challenging to resect using a minimally invasive fashion; therefore, conventional open resection is still the technique of choice today. In this video, we demonstrated our approach of an open parenchymal-sparing posterosuperior liver resection for a colorectal liver metastasis.

Abstract
Portal lymphadenectomy is an integral part of gallbladder, intrahepatic cholangiocarcinoma, and perihilar cholangiocarcinoma resection to improve staging and prognostication. This is also believed by many oncologists to potentially serve as therapy to remove cancer containing nodes. While the current guideline requires removal of at least 6 portal lymphnodes, many surgeons face technical difficulty in performing the systematic portal lymphadenectomy especially in minimally invasive fashion. The anatomical complexity of biliovascular structures within the porta hepatis contributes to this technical challenge. In this video, we demonstrate our robotic technique of systematic portal lymphadenectomy for the treatment of gallbladder cancer.

Abstract
This study was undertaken to determine surgical outcomes of patients undergoing robotic hepatectomy for hepatocellular carcinoma (HCC) and to investigate the correlation between tumor distance to margin and perioperative outcomes, as well as overall survival (OS). To our knowledge, this study represents the largest series of robotic liver resection for HCC in North America. We retrospectively analyzed 58 consecutive patients who underwent robotic liver resection for HCC. Patients were further stratified by tumor distance to margin (≤ 1 mm, 1.1-9.9 mm, ≥ 10 mm) and their clinical outcomes including OS were compared. A majority of patients attained a greater than 1 mm tumor distance to margin (81%). There were no differences in tumor size between patient cohorts who attained ≤ 1 mm, 1.1-9.9 mm, and ≥ 10 mm margins. There were no differences in pre-, intra-, and postoperative outcomes among the three cohorts. Cost variables of interest were also similar. OS was highest in the > 10 mm margin cohort, and this was statistically significant at 3 and 5 years. Robotic HCC resection was associated with adequate tumor distance to margin. Wide margins ≥ 10 mm are associated with the best OS.

Abstract
The genera Paramoeba and Neoparamoeba (Amoebozoa, Dactylopodida, Paramoebidae) include well-known opportunistic pathogens associated with fish (N. peruans; amoebic gill disease), lobsters, molluscs and sea urchins, but only rarely with crabs (grey crab disease of blue crabs). Following reports of elevated post-capture mortality in edible crabs Cancer pagurus captured from a site within the English Channel fishery in the UK, a novel disease (amoebic crab disease, ACD) was detected in significant proportions of the catch. We present histopathological, transmission electron microscopy and molecular phylogenetic data, showing that this disease is defined by colonization of haemolymph, connective tissues and fixed phagocytes by amoeboid cells, leading to tissue destruction and presumably death in severely diseased hosts. The pathology was strongly associated with a novel amoeba with a phylogenetic position on 18S rRNA gene trees robustly sister to Janickina pigmentifera (which groups within the current circumscription of Paramoeba/Neoparamoeba), herein described as Janickina feisti n. sp. We provide evidence that J. feisti is associated with ACD in 50% of C. pagurus sampled from the mortality event. A diversity of other paramoebid sequence types, clustering with known radiations of N. pemaquidensis and N. aestuarina and a novel N. aestuarina sequence type, was detected by PCR in most of the crabs investigated, but their detection was much less strongly associated with clinical signs of disease. The discovery of ACD in edible crabs from the UK is discussed relative to published historical health surveys for this species.

Abstract
BackgroundIxekizumab (IXE), an IL-17A inhibitor, has demonstrated efficacy in clinical trials1-3 but real-world effectiveness (RWE) data are limited.4ObjectivesTo describe changes in disease activity and patient-reported outcomes (PROs) at 6 and 12 months follow-up among psoriatic arthritis (PsA) patients initiating IXE in a routine clinical setting.MethodsThis retrospective cohort study included patients from the OM1 PsA Registry (OM1, Boston, MA), a linked electronic medical record and administrative claims dataset with over 50,000 patients. Eligible patients had ≥1 prescription for IXE (first = index), were ≥18 years old at index, had ≥1 diagnosis code for PsA in the 12 months before or on index, and had ≥12 months of baseline and ≥6 months of follow-up data as of June 2021. For patients with baseline and follow-up measures available, changes in Clinical Disease Activity Index (CDAI), PROs, and other clinical outcomes from baseline to 6 and 12 months were described. For patients on IXE monotherapy, change in CDAI score from baseline to 6 and 12 months was assessed using mixed effects linear models adjusted for age, sex, and baseline CDAI score.ResultsThe study population included 1,812 patients with a mean age of 53.7 years (Table 1). Psoriasis was present in 82% and enthesitis in 28%. Over 60% of patients were obese, and the mean Charlson Comorbidity Index was 1.3. Most patients (84%) had prior treatment with a biologic disease-modifying antirheumatic drug (bDMARD) and 40% with a targeted synthetic DMARD (tsDMARD). The mean number of bDMARDs and tsDMARDs used during all available prior history was 2.3 and 1.1, respectively. The most common prior bDMARDs were secukinumab (n=428, 24%) and adalimumab (n=245, 14%).Table 1.Demographic and Clinical Characteristics by Therapy StatusAll Patients(N=1,812)Monotherapy(N=1,485)Combination Therapy(N=327)Age (years)Mean (s.d.)53.7 (12.2)53.9 (12.3)52.9 (11.7)Median (Q1-Q3)55 (46-62)55 (46-62)54 (45-61)SexFemale1,108 (61.1%)909 (61.2%)199 (60.9%)Male704 (38.9%)576 (38.8%)128 (39.1%)Charlson Comorbidity IndexMean (s.d.)1.3 (1.6)1.3 (1.6)1.5 (1.7)Median (Q1-Q3)1 (0-2)1 (0-2)1 (0-2)BMIUnderweight: <18.510 (0.6%)10 (0.7%)0 (0.0%)Normal weight: 18.5-24.9210 (12.2%)172 (12.2%)38 (12.1%)Overweight: 25-29.9455 (26.5%)379 (27.0%)76 (24.2%)Obese: >= 301,045 (60.8%)845 (60.1%)200 (63.7%)Missing927913Domains of PsA: PsoriasisYes1,490 (82.2%)1,222 (82.3%)268 (82.0%)No322 (17.8%)263 (17.7%)59 (18.0%)Domains of PsA: EnthesitisYes510 (28.1%)409 (27.5%)101 (30.9%)No1,302 (71.9%)1,076 (72.5%)226 (69.1%)Of patients with a baseline CDAI score, 61% had moderate or severe disease activity. For all patients, CDAI scores improved (decreased) by an average of 3.4 and 3.7 points at 6 and 12 months, respectively, from a baseline mean of 15.4. All disease activity measures and PROs improved from baseline to 6 and 12 months (Figure 1). In patients persistent with IXE, 35.3% and 33.7% were in CDAI remission or low disease activity at 6 and 12 months after initiation, respectively. For IXE monotherapy users (82% of patients), at baseline, patients had a mean CDAI of 14.3 (n=131) and 15.1 (n=105) for the 6 and 12 month analyses, respectively. Adjusted mean changes in CDAI from baseline to 6 months (-3.6 points, p < 0.0001) and 12 months (-4.9 points, p < 0.0001) were statistically significant.ConclusionIn this cohort of PsA patients with multiple prior b/tsDMARD failures, improvements in disease activity and PROs were observed at 6 and 12 months after initiating treatment with IXE.

Abstract
BACKGROUND Concerns regarding minimally invasive liver resection of intrahepatic cholangiocarcinoma (IHCC) include inadequate resection margins and inferior long-term overall survival (OS) when compared to an "open" approach. Limited data exists to address these issues. We aimed to compare perioperative variables, tumor distance to margin, and long-term outcomes after IHCC resection based on surgical approach (robotic vs open) in our hepatobiliary center to address these concerns. METHODS With IRB approval, 34 patients who underwent robotic or open hepatectomy for IHCC were prospectively followed. Patients were stratified by tumor distance to resection margin (≤1 mm, 1.1-9.9 mm, ≥10 mm) for illustrative purposes and by approach (robotic vs open). Where appropriate, regression analysis and cox model of proportional hazards were utilized. Survival was stratified by margin distance and approach utilizing Kaplan-Meier curves. Data are presented as median (mean ± SD). RESULTS Patients undergoing robotic vs open hepatectomy had similar demographics. Patients undergoing the robotic approach had significantly lower estimated blood loss (EBL). Tumor distance to margin between the two approaches were similar (P = .428). Median OS between the two approaches was similar in patients of any margin distance.In the subgroup analysis by margin distance, the robotic approach yielded less EBL for patients in the 1.1-9.9 mm and ≥10 mm margin groups, and a shorter ICU length of stay for patients with ≥10 mm margin. DISCUSSION Similar margins were attained via either approach, translating into oncological non-inferiority of robotic IHCC resection. Robotic approach for the treatment of IHCC should be considered an alternative to an open approach.

Abstract
INTRODUCTION Thrombocytopenia is a known surrogate marker for cirrhosis and portal hypertension and has been associated with increased risk of poor perioperative outcomes when studied in "open" operations. This study was undertaken to assess thrombocytopenia as an independent risk factor for undesirable perioperative outcomes after robotic hepatectomy. METHODS We retrospectively reviewed 279 patients who underwent robotic hepatectomy at our institution. Patients were stratified into two cohorts based on preoperative platelet counts. Thrombocytopenia was classified as having a platelet count less than 150 /μL. Patients were 2:1 ratio propensity-score matched based on IWATE score and age. Data are presented as median (mean ± SD). RESULTS Thirty-six patients with thrombocytopenia were matched to 72 patients without thrombocytopenia. Patients with thrombocytopenia had higher MELD scores [p = 0.02] and higher Child-Pugh Scores [p <0.001]. Intraoperatively, patients with thrombocytopenia had shorter operative duration [p = 0.03] but similar estimated blood loss (EBL) [p = 0.78]. Postoperatively, there were more fresh frozen plasma transfusions in patients with thrombocytopenia [p = 0.04]. There were no differences in IWATE scores, tumor size, conversions to "open" operations, intraoperative complications, patient length of stay (LOS), Clavien-Dindo score ≥ III complications, perioperative RBC transfusion, in-hospital mortality, or 30-day readmissions. CONCLUSIONS In our propensity-score matched study, patients with thrombocytopenia had more severe liver disease; however, there were no differences in their EBL, LOS, or perioperative complications. Preoperative thrombocytopenia, while being an indicator of severity of liver disease potentially promoting perioperative bleeding, does not negatively affect the perioperative course of patients undergoing robotic hepatectomy.

Abstract
The majority of retroperitoneal mass excision is performed via conventional "open" laparotomy due to concerns of technical difficulty and adequate oncological margins in cases of a malignant sarcoma. A very few cases of minimally invasive resection by laparoscopy had been reported in the literature. Despite the rapid adoption of robotic technology in general surgery and surgical oncology, the robotic technique has not been applied for this pathology. We discussed a complete resection of a large perinephric tumor using a robotic platform. To our knowledge, this is the first study to report the robotic technique of retroperitoneal tumor excision, highlighting the application and usefulness of intraurethral indocyanine green (ICG) injection.
