Cosmesis, patient satisfaction, and quality of life after da Vinci Single-Site cholecystectomy and multiport laparoscopic cholecystectomy: short-term results from a prospective, multicenter, randomized, controlled trial.

BACKGROUND: Single-incision laparoscopic cholecystectomy evolved from the traditional multiport laparoscopic technique. Prior trials have demonstrated improved cosmesis with the single-incision technique. Robotic single-site surgery minimizes the technical difficulties associated with laparoscopic single-incision approach. This is the first prospective, randomized, controlled study comparing robotic single-site cholecystectomy (RSSC) and multiport laparoscopic cholecystectomy (MPLC) in terms of cosmesis and patient satisfaction. METHODS: Patients with symptomatic benign gallbladder disease were randomized to RSSC or MPLC. Data included perioperative variables such as operative time, conversion and complications and cosmesis satisfaction, body image perception, quality of life using validated questionnaires, at postoperative visits of 2, 6 weeks and 3 months. RESULTS: One hundred thirty-six patients were randomized to RSSC (N = 83) and MPLC (N = 53) at 8 institutions. Both cohorts were dominated by higher enrollment of females (RSSC = 78%, MPLC = 92%). The RSSC and MPLC cohorts were otherwise statistically matched. Operative time was longer for RSSC (61 min vs. 44 min, P < 0.0001). There were no differences in complication rates. RSSC demonstrated a significant superiority in cosmesis satisfaction and body image perception (P value < 0.05 at every follow-up). There was no statistically significant difference in patient-reported quality of life. Multivariate analysis of female patients demonstrated significantly higher preference for RSSC over MPLC in cosmesis satisfaction and body image perception with no difference seen in overall quality of life. CONCLUSIONS: Results from this trial show that RSSC is associated with improved cosmesis satisfaction and body image perception without a difference in observed complication rate. The uncompromised safety and the improved cosmesis satisfaction and body image perception provided by RSSC for female patients support consideration of the robotic single-site approach.

R-LESS right colectomy with the single-site® robotic platform.

BACKGROUND: Use of robotics has exemplified single-site procedures by restoring the correct hand-instrument alignment and providing stable, stereoscopic visual field. Technique was initially introduced by the manufacturers for cholecystectomy, but experienced teams quickly extended the indications to more complex procedures. We hereby present a case of a patient that underwent robotic right colectomy and omentectomy through the single-site(®) platform. METHODS: A single-site procedure was offered to our 58-year-old male patient with carcinoma of the ascending colon and he gave written consent for it. The VESPA(®) single-site platform was used according to the standards of the manufacturing company. The single-site port(®) was placed at the umbilicus. Rest of setup and procedure steps were based on the multiport technique. An extended omentectomy accompanying the right colectomy has not previously reported to our knowledge. After sufficient mobilization specimen was exteriorized through the umbilicus, excised and the anastomosis was performed using linear staplers. RESULTS: Console time was 164 min and total operation time was 221 min. Intraoperatively, there was no need for conversion, additional ports or blood transfusions. Total console time was 164 min. Lacking of wristed instruments and bipolar energy were regarded as serious limitations. No drains were used. Patient did not require ICU stay and had no postoperative complaints. He was given liquid diet on PO day #2 and he was discharged on PO day #4. CONCLUSIONS: Robotic single-site right colectomy is safe and feasible in selected cases. Experience from single-site robotic cholecystectomy is a useful basis to expand the indications to more complex procedures. Further development of the instruments and large number of cases may justify the indications for using this technique in the future.

Cholecystectomy using a novel Single-Site(®) robotic platform: early experience from 45 consecutive cases.

BACKGROUND: The aim of this work was to study the feasibility, safety, and efficacy of single-incision robotic cholecystectomy using a novel platform from Intuitive Surgical. METHODS: All operations were performed by the same surgeon. Parameters assessed included patient history, indication for surgery, operation time, complication rate, conversion rate, robot-related issues, length of hospital stay, postoperative pain, and time to return to work. All patients were followed for a 2-month period postoperatively. RESULTS: Forty-five patients (22 women, 23 men) underwent single-incision robotic cholecystectomy from March 1 to July 15, 2011. There were no conversions to either conventional laparoscopy or laparotomy, although in three cases a second trocar was used. There were no major complications apart from a single case of postoperative hemorrhage. Average patient age was 47 ± 12 years (range = 27-80 years) and average BMI was 30 kg/m(2) (mean = 28.8 ± 4 kg/m(2), range = 18.4-46.7 kg/m(2)). The primary indication for surgery was gallstones. The mean operation time (skin-to-skin) was 84.5 ± 25.5 min (range = 51-175 min), docking time was 5.8 ± 1.5 min (range = 4-11 min), and console time (net surgical time) was 43 ± 21.9 min (range = 21-121 min). Intraoperative blood loss was negligible. There were no collisions between the robotic arms and no other robot-related problems. Average postoperative length of stay was less than 24 h. The mean Visual Analog Pain Scale Score 6 h after the operation was 2.2 ± 1.51 (range = 0-6) and patients returned to normal activities in 4.48 ± 2.3 days (range = 1-9 days). CONCLUSIONS: Single-Site(®) is a new platform offering a potentially more stable and reliable environment to perform single-port cholecystectomy. Both simple and complicated cholecystectomies can be performed with safety. The technique is possible in patients with a high BMI. The induction of pneumoperitoneum using the new port and the docking process require additional training.

Laparoscopic excision of malignant struma ovarii and 1 year follow-up without further treatment.

OBJECTIVE: To report the case of a patient with malignant struma ovarii, which was excised endoscopically. DESIGN: Case study and literature review. SETTING: Hospital outpatient clinic with subsequent hospitalization. PATIENT(S): A 40-year-old gravida 5, para 3 with an incidental ultrasonographic finding of a solid right adnexal mass. INTERVENTION(S): Endoscopic resection and 1-year follow-up. MAIN OUTCOME MEASURE(S): Treatment options and differential diagnosis. RESULT(S): The tumor was excised endoscopically. CONCLUSION(S): Malignant struma ovarii is a very rare, highly specialized form of mature ovarian teratoma, in which thyroid tissue is the predominant element. Because of the nonspecific symptoms and a lack of specific features in imaging studies, preoperative diagnosis is very difficult, and there is no standard treatment. Struma ovarii, which is potentially malignant, should be included in the differential diagnosis of an ovarian mass with cystic, solid, or mixed cystic and solid structure. Standardized treatment of malignant struma ovarii still remains undefined; currently the laparoscopic removal of the tumor may be a treatment option, and thyroidectomy and radiotherapy with 131I should be offered.
