Crohn's disease is an incurable inflammatory disorder that can affect the entire gastrointestinal tract. While medical management is considered first-line treatment, approximately 70-90% of patients with Crohn's disease will require at least one surgical intervention during the course of their lifetimes. Traditionally, abdominal surgery for Crohn's disease has been performed via an open approach with an increasing adoption of minimally invasive techniques. The aim of this study was to evaluate and compare postoperative outcomes from an initial national experience with robotic-assisted ileocolic resection for Crohn's disease...

Minimally invasive technique has been adopted as the standard of care in many surgical fields within general surgery. Hepatobiliary surgery, however, is lacking behind due to the complex nature of the operation and concerns of major bleeding. Several centers suggested that inherent limitations of conventional laparoscopy precludes its wide adoption. Robotic technique provides solutions to these limitations. In this study, we report our standardized technique of robotic left hepatectomy. We discuss aspects of robotic hepatectomy and describe our standardized approach for robotic left hepatectomy...

Duodenal stenosis is one of the leading causes of duodenal obstruction in the pediatric population, usually diagnosed in newborns and in Down syndrome patients. It has historically been treated with duodeno-duodenostomy, an operation that is now commonly performed laparoscopically. We present a case of a 10-year-old child with a rare chromosomal abnormality who was diagnosed with a duodenal stricture after presenting with failure to thrive and inability to tolerate tube feeds. Duodeno-duodenostomy was performed using the da Vinci® robot, allowing for improved intra-operative range of motion and control during anastomosis creation, with the same cosmetic benefits of laparoscopic surgery, and subsequent improvement in symptoms postoperatively...

Minimally invasive radical prostatectomy has rapidly been adopted as the primary means of surgical intervention for prostate cancer. Intraoperative tissue retraction relies on either gravity (via positioning) or use of additional ports and instrumentation. We report the use of a novel trocar-less magnetic retractor system to aid with tissue retraction. Three patients underwent robotic-assisted radical prostatectomy in the treatment of prostatic adenocarcinoma at a single tertiary care institution. All surgeries utilized the Levita™ Magnetic Surgical System (San Mateo, CA) without the use of a fourth robotic arm...

Widespread spinal metastases can obscure bone landmarks and severely hinder surgical safety during pedicle screw insertion. Robot-assisted spinal surgery has demonstrated an excellent safety profile for pedicle screw insertion. Moreover, spinal surgery robotic systems can facilitate pedicle screw insertion with high-accuracy. We present a patient who had breast cancer with widespread spinal metastases, pathological vertebral fracture, and spinal cord compression with a challenge of intraoperative image recognition...

A 33-year-old female presented to the emergency department of our hospital with urosepsis and hematuria with clot retention secondary to a complicated pyelolithotomy for left-sided pelvic calculus. A percutaneous nephrostomy was placed for drainage as a DJ stent could not be traversed into the left renal pelvis with retrograde pyelography demonstrating complete cut-off at L4-L5 level. After stabilization, she was found to have uretero-pelvic junction obstruction (UPJO) in left solitary functioning kidney with long-segment upper ureteric stricture and nadir serum creatinine 1...

Vasovasostomy success rates improved with the application of the operative microscope in 1975. The robotic platform offers potential advantages including: a stable, ergonomic, scalable control system with three-dimensional visualization and magnification, the elimination of physiological tremor, and simultaneous control of three instruments and a camera. A previous publication revealed a fellowship-trained microsurgeon (PKK) could transition to robot-assisted microsurgical vasovasostomy (RAVV) with comparable outcomes...

To evaluate peri- and post-operative outcomes after robotic partial nephrectomy (RPN) in patients with a solitary kidney. A multi-institutional database of 1868 patients was used to identify 35 patients with a solitary kidney who underwent RPN at six different centers from 2007 to 2016. Peri-operative outcomes were summarized with descriptive statistics. We assessed the change in eGFR over time with a linear mixed-effects model. Median operative time, ischemia time, and estimated blood loss were 172 min, 16 min, and 113 mL, respectively...

Despite advantages of minimally invasive surgery, many hepatobiliary surgeons are hesitant to offer this approach for major hepatic resection due to concerns of difficulty in liver manipulation, bleeding control, and suboptimal oncologic outcomes. The robotic surgical system has revolutionized the way traditional laparoscopic liver resection is undertaken. Limitations of traditional laparoscopy are being resolved by robotic technology. We aimed to describe aspects of minimally invasive liver surgery and our standardized technical approach...

A 51-year-old man who was a hepatitis B carrier presented with ruptured hepatocellular carcinoma (HCC). Hepatic arterial embolization was performed for control of bleeding which was followed by staged open left lateral sectionectomy for tumor removal. Pathology confirmed a 3.5 cm ruptured subcapsular HCC in a cirrhotic liver with clear resection margin. However, the alpha-fetoprotein (AFP) increased from 14 to 72 µg/L after 7 months. A 1.7 × 0.8 cm nodule at left subdiaphragmatic region abutting on the spleen but no intrahepatic lesion was seen on computed tomography (CT)...

Complete R0 resection of gastrointestinal stromal tumors (GIST) of the stomach without signs of metastasis is highly reported, and the techniques for tumor resection have been evolving. Previously, laparoscopy was suggested to be safe only for GIST tumors < 2 cm. More recent reports demonstrate safety of resecting gastric GIST tumors laparoscopically > 5 cm even in unfavorable locations defined as GE junction, lesser curvature of gastric body, posterior wall of gastric body, and antrum. The most common resection method for gastric GIST resection is wedge resection, regardless if the surgery is completed open, laparoscopic, or robotically...

Robot-assisted surgery is limited by the lack of haptic feedback and increased operating times. Force scaling adjusts feedback transmitted to the operator through the use of scaling factors. Herein, we investigate how force scaling affects forces exerted in robotic surgery during simple and complex tasks, using a pneumatic surgical robot, IBIS VI. Secondary objectives were to test the effects of force scaling on operating time, depth of needle insertion and user satisfaction. Two novice males performed simple (modified block transfer) and complex (needle insertion) tasks under four scaling factors: 0...

OBJECTIVE: To present our technique of robotic retrorectus parastomal hernia repair. BACKGROUND: Parastomal hernias represent a significant problem with high recurrence and long-term complications. An estimated of 120,000 new stomas are created per year with a prevalence of up to 800,000 patients in the U.S. 40-60% of these ostomies will never be reversed. Parastomal hernias cause skin breakdown and make adherence of ostomy appliances difficult, creating the need for frequent bag exchanges...

Laparoscopic esophageal myotomy is the standard surgical intervention for achalasia. Compared to standard laparoscopic techniques, use of the robot has theoretical advantages of improved visualization and dexterity. We evaluated the University of Arizona's experience with the two alternatives to compare outcomes. Patients who underwent either laparoscopic or robot-assisted myotomy were identified from a retrospective database from 1/1/2006 to 12/31/2015. Patient demographics, prior treatment, intra-operative complications, operative time, post-operative length of stay and complications, and long-term results were compared between the two groups...
