Background. While laparoscopy is currently adopted for hepatic resections, robotic approaches to the liver have not gained wide acceptance. We decided to analyze the learning curve in the field of robotic liver surgery comparing short-term outcomes between the first and the second half of our series. Methods. We retrospectively reviewed demographics and clinical data of patients who underwent robotic liver resection at our institution from July 2014 through September 2017. 60 patients diagnosed with primary or secondary liver neoplasms or hydatid disease were included in this study. ASA PS >3, heart failure, respiratory insufficiency, and general contraindication to pneumoperitoneum were exclusion criteria. Results. 60 patients were included. We observed a statistically significant decrease in operative time (p<0.001), intraoperative blood loss (p=0.01), and postoperative complications (p<0.001) after 30 cases. From the interpretation of the CUSUM curve, the time of operation appears to be significantly reduced after the first 30 operations. Discussion. This is the first European analysis of the learning curve for robotic liver resection in an HPB and liver transplant referral center. However, more studies are needed to confirm such results outside a HPB referral center. This is crucial to develop formal credentialing protocols for both junior and senior surgeons.

Abstract Background Laparoscopic liver resection (LLR) has been progressively developed along the past two decades. Liver surgery was one of the last frontiers reached by minimally invasive surgery. Surgical technique and equipment evolved to overcome technical limitations, making laparoscopic liver resections (LLR) safe and feasible. Surgeons developed skills in a stepwise approach, beginning with low complexity operations for benign diseases and reaching high-complexity surgeries for malignant cases and living donor organ harvesting. Objective s: The aim of the study is to compare short term results of laparoscopic versus open hepatectomy regarding to intra operative details and post-operative management and complications for achieving a safe hepatic resection for treatment of HCC in cirrhotic patients. Patients and Methods In this prospective study, a comparison between laparoscopic resection and open resection was done to compare short-term results between laparoscopic and open liver resection. This study was conducted on 30 patients with hepatocellular carcinoma. 15 patients (50%) were treated by laparoscopic liver resection (Group A) while the other 15 patients (50%) were treated by open liver resection (Group B). Results Regarding the demographic data, the presence of past history of medical condition and the preoperative laboratory results, no statistical significance was found. The mean operative time has statistically significant difference between the 2 groups, with decreased operative time in the laparoscopic group (P &lt; 0.001). The mean blood loss has no statistically significant difference relations between the 2 groups, (P = 0.866) with conversion rate of (13.3%) happened in two cases. Conclusion Laparoscopic liver resection is a safe and feasible treatment option for HCC in cirrhotic patient needing minor resection at laparoscopic segments (II, III, IVa,V,VI). Laparoscopic liver resection for HCC has superior short- term and comparable oncological outcomes to open liver resection. LLR should be performed for carefully selected patients and by an expert surgical team.

Robotic liver resection is being introduced with its potential to overcome limitations of conventional laparoscopy. This study was undertaken to document early experience and learning curve of robotic liver resection in our institution. All patients undergoing liver resection between 2013 and 2017 were prospectively followed. Patients were divided into three consecutive tertiles (cohort I–III). Thirty-three patients underwent robotic liver resection within the study period. Twenty-four per cent of patients underwent formal right or left hemihepatectomy, 21 per cent underwent sectionectomy, 6 per cent underwent central hepatectomy, and the remainder underwent non-anatomical liver resection. Formal hemihepatectomy and right posterosuperior segment resection were undertaken in two patients in cohort I, four patients in cohort II, and four patients in cohort III. Two cases were converted to “open” operation. Operative time was 172 (194.5 ± 65.1) minutes in cohort I, 222 (247.8 ± 109.8) minutes in cohort II, and 280 (302.5 ± 84.9) minutes in cohort III, reflecting increasing degree of technical complexity. Estimated blood loss decreased significantly throughout the cohorts, being 400 mL, 200 mL, and 100 mL in cohorts I to III, respectively. Major intraoperative complications were not seen. Three patients experienced postoperative complications, resulting in a single mortality. Length of hospital stay was three days, with two patients being readmitted within 30 days. Robotic technique for liver resection is feasible and safe. It offers good short-term clinical outcomes, including for patients who require major liver resection. As the proficiency developed, a notable improvement in technically ability to undertake more complex resections with decreasing blood loss and minimal morbidity was seen.

AbstractTo evaluate whether the learning curve for sleeve gastrectomy could be completed after 50 cases. First 100 patients undergoing LSG under a newly trained laparoscopic surgeon were included in this study and divided into two groups of 50 consecutive patients each. Perioperative outcomes were compared to recently introduced global benchmarks. Short-term weight loss was calculated as Total Weight Loss Percent (%TWL) and complications were classified in accordance with the Clavien–Dindo classification. CUSUM analysis was performed for operative time and hospital stay. Mean preoperative age and BMI were 41.8 ± 10.3 years and 42.9 ± 5.4 kg/m2, respectively. Demographics and rate of patients with previous surgery were comparable preoperatively in the two groups. Mean operative time was 92.1 ± 19.3 min and hospital stay was 3.4 ± 0.6 days as per our standard protocol of discharge. Uneventful postoperative course was recorded in 93% of patients and only one case of staple line leak was registered in the first 50 cases (group 1). No statistical difference in BMI and %TWL was found between the two groups at any time of follow-up. Comparison between two groups showed a significant reduction in hospital stay and operative time after the first 50 LSGs (p < 0.05). LSG can be performed by newly trained surgeons proctored by senior tutors. At least 50 cases are needed to meet global benchmark cut-offs and few more cases may be required to reach the plateau of the learning curve.

Minimally invasive surgery techniques are expanding in utilization in liver resections and now include robotic approaches. Robotic liver resection has been demonstrated to have several benefits, including surgeon ergonomics, wrist articulation, and 3D visualization. Similarly, for multivisceral liver resections, the use of minimally invasive techniques has evolved and expanded from laparoscopy to robotics. The aim of this article is to review the literature and describe multivisceral resections, including hepatectomy, using a robotic technique. We describe over 50 published cases of simultaneous robotic liver resection with colon or rectal resection. In addition, we describe several pancreatectomies performed with liver resection and one extra-abdominal pulmonary resection with liver resection. In total, these select reported cases at experienced centers demonstrate the safety of robotic multivisceral resection in liver surgery with acceptable morbidity and rare conversion to open surgery. As robotic technology advances and experience with robotic techniques grows, robotic multivisceral resection in liver surgery should continue to be investigated in future studies.

Background Remote-access thyroid and parathyroid surgery has gained popularity recently due to its benefit of avoiding visible neck scars. Most of these techniques were described and performed in Asia, on patients with different body habitus compared to American patients. We aim to analyze the learning curve in performing these operations in North America.  Methods This is a retrospective cohort study of a 10-year experience by a single surgeon at a North American institute. Patients who underwent thyroid or parathyroid procedures by a transaxillary, retroauricular, or transoral endoscopic thyroidectomy vestibular approach (TOETVA) were included. Cumulative sum (CUSUM) was used to analyze learning curves based on intraoperative blood loss and total operative times and learning phases were divided accordingly. Results Three hundred seventy-two remote-access thyroid and parathyroid procedures were performed during the study period. Total operative time for transaxillary procedures was initially reduced after the 69th procedure and then again after the 134th case. For retroauricular procedures, marked reduction in the operative time was observed after 21 procedures. Most patients (57.02%) were discharged home on the same day during the mastering phase. In the transaxillary procedures, only 1 case of brachial plexus injury occurred prior to the routine use of somatosensory evoked potential (SSEP) monitoring. Discussion Remote-access thyroid and parathyroid surgeries can be performed safely with minimal complications in a select group of patients. Analysis of the learning curve in performing these operations aids in structuring a safe and effective learning period for endocrine surgeons seeking to venture into this modality of treatment.
