Robotic-assisted ventral hernia repair: a multicenter evaluation of clinical outcomes.

Background: The open approach continues to be widely performed for ventral hernia repair, while the minimally invasive laparoscopic approach has grown adoption over the last decade. Recently, robotic operation was described as a new modality due to the ease for performing intracorporeal closure of the hernia defect. This study is one of the first multi-institutional case series evaluating robotic-assisted laparoscopic ventral hernia repairs, with the goal of describing robotic-assisted surgical techniques for ventral and incisional hernia repair and the outcomes in teaching and community hospital settings.

A multicenter study of initial experience with single-incision robotic cholecystectomies (SIRC) demonstrating a high success rate in 465 cases.

Background: Recently, the robotic single-site platform has been used to ameliorate the difficulties seen in single-incision laparoscopic surgery (SILC) while preserving the benefits of standard laparoscopic cholecystectomy. The purpose of this study is to describe the clinical outcomes of a large series of single-incision robotic cholecystectomy (SIRC).

Methods: Medical records of consecutive patients who underwent SIRC were retrospectively reviewed.

Gastropleural fistula after bariatric surgery: a report of two cases.

Introduction: Gastropleural fistulas (GPF) were first described by Markowitz and Herter in 1960. These are uncommon entities and can occur as a consequence of pulmonary surgery, trauma, malignancy, hiatal hernia, infections, Nissen fundoplication and most recently, bariatric surgery. Many treatments have been used for GPF, such as conservative management with antibiotics, parenteral nutrition, percutaneous drainage of collections and endoscopic therapies, but these usually fail and may lead to complex surgical procedures.

Intravenous acetaminophen in bariatric surgery: effects on opioid requirements.

Background: Opioids are commonly used after bariatric surgery for pain control because of their potent analgesic effects. Nevertheless, the morbidly obese patient has increased risk for developing adverse effects produced by opioids (such as sedation, apnea, hypoxemia, ileus, and vomiting). Intravenous acetaminophen (IVA) has been evaluated in some specialties showing a reduction in opioid consumption.

A comparative retrospective study of robotic sleeve gastrectomy vs robotic gastric bypass.

Background: The introduction of the robotic platform to bariatric surgery has brought forth a novel approach, with modifications to the standard laparoscopic sleeve gastrectomy (LSG) and laparoscopic gastric bypass (LGB). The purpose of this study was to match robotic gastric bypass (RGB) vs robotic sleeve gastrectomy (RSG) and compare them to those observed with the laparoscopic platform.

Methods: A retrospective data collection of RSGs and RGBs from a single institution was performed.

Laparoscopic ventral hernia repair with primary closure versus no primary closure of the defect: potential benefits of the robotic technology.

Background: Some authors recommend primary closure of the defect before placement of the mesh. The purpose of this study is to compare laparoscopic ventral hernia repair (LVHR) without primary closure of the defect (NPCD) versus LVHR with primary closure of the defect (PCD).

Methods: A retrospective review of 134 LVHR was performed.

Rare use of robotic surgery for removal of large urachal carcinoma.

Minimally invasive surgery has been used traditionally for removal of colorectal, gastric and gallbladder disease pathologies with great success. Many advantages have been demonstrated with the addition of robotic surgery, such as 3-D visualization, articulation of instruments and improved surgeon ergonomics while operating. These benefits have allowed the implementation of robotic surgery into new areas.

Impact of fellowship during single-incision laparoscopic cholecystectomy.

Background And Objectives: Minimally invasive surgery fellowship programs have been created in response to advancements in technology and patient's demands. Single-incision laparoscopic cholecystectomy (SILC) is a technique that has been shown to be safe and feasible, but this appears to be the case only for experienced surgeons. The purpose of this study is to evaluate the impact of minimally invasive surgery fellow participation during SILC.

Robotic repair of giant paraesophageal hernias.

Background And Objectives: Giant paraesophageal hernia accounts for 5% of all hiatal hernias, and it is commonly seen in elderly patients with comorbidities. Some series report complication rates up to 28%, recurrence rates between 10% and 25%, and a mortality rate close to 2%. Recently, the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) has shown equivocal benefits when used for elective surgeries, whereas for complex procedures, the benefits appear to be clearer.

Single-incision cholecystectomy: a comparative study of standard laparoscopic, robotic, and SPIDER platforms.

Background: Many series have shown the feasibility and safety of single-incision laparoscopic cholecystectomy (SILC), but this technique still has limitations such as instrument collisions and lack of triangulation. Recently, two single-incision platforms, robotic and SPIDER, have attempted to ameliorate such problems. This study aimed to compare three different techniques of single-incision cholecystectomy: standard laparoscopic, robotic, and SPIDER approaches.
