Robotic Versus Laparoscopic Adrenalectomy: Pluriannual Experience in a High-Volume Center Evaluating Indications and Results.

Background: Robotic adrenalectomy offers several clinical benefits if compared with laparoscopic adrenalectomy; however, its superiority is still under debate. The aim of this study was the investigation of differences between the two techniques, and a comparison when approaching right or left side adrenal lesions was further conducted. Materials and Methods: All patients undergoing laparoscopic and robotic unilateral adrenalectomy at our institution from January 2006 to December 2019 were collected and retrospectively analyzed. Statistical analysis was conducted; differences between the two cohorts were reported. Results: A total of 160 cases were included (84 patients in laparoscopic adrenalectomy-group [LA-g] 76 cases in robotic adrenalectomy-group [RA-g]). The groups were homogeneous for demographic data. No intraoperative complications were reported; mean amount of intraoperative blood loss was comparable. No cases of conversion to open surgery were required. RA-g presented a longer operative time than LA-g for right adrenalectomy (P = .05), no differences were noted for left side (P = .187). Overall morbidity was 21% for LA-g and 10.5% for RA-g (P = .087), with an inferior rate of surgical complications for RA-g (P = .024), and for robotic left adrenalectomy than robotic right procedure (P = .03). Length of hospital stay was shorter for RA-g (P = .005). Conclusions: Robotic adrenalectomy presents similar outcomes as laparoscopic approach with some benefits for selected cases. Left adrenal lesions seem to receive greater advantages from robotic technique. Large randomized controlled trials are required to determine the role of robotic adrenal surgery and if the indication can be standardized based on the laterality of adrenal procedure.

Full robotic multivisceral resections: the Modena experience and literature review.

The robotic platform is becoming a multidisciplinary tool, versatile, and suitable for multiple procedures. Combined multivisceral resections may represent an alternative to sequential procedures with a potential favorable impact on postoperative morbidity, and on the timing of administration of adjuvant chemotherapy. We herein present our initial experience with full robotic multivisceral resections, and a review of the literature available. Between January 2018 and April 2020, 11 patients underwent multivisceral full robotic abdominal surgery: 4 patients presented with two synchronous tumors, 4 with primary cancer associated with a benign condition and 3 cases involved deep infiltrating endometriosis. Surgical teams enrolled were: General Surgery, Urology and Gynecology. A systematic bibliographic research up to April 2020 was conducted in PubMed. 4 colorectal resections combined with partial or radical nephrectomy were performed, as well as 2 right colectomies in combination with right adrenalectomy and gastric banding removal, 2 radical prostatectomies with Nissen Fundoplication and abdominal wall hernia repair, and 3 resections of deep pelvic endometriosis with colorectal involvement. Mean total operative time was 367 min. No intraoperative complication or conversion to open was registered. Overall postoperative complication rate was 18.2%. 26 papers were included in the review (10 case series and 16 case reports) with a total of 156 combined multivisceral robotic procedures recorded. Robotic combined multivisceral resections proved to be safe and feasible when performed in high volume centers by expert surgeons. The heterogeneity of reports does not allow for a standardization of the procedure. Further studies and accumulation of experience are needed.

An unexpected finding after robotic subtotal gastrectomy: Vomiting of Taenia Saginata.

INTRODUCTION: Most Human taeniasis are asymptomatic or associated with vague clinical manifestations, but cases of unusual migration of these parasites have been described. PRESENTATION OF A CASE: A case of challenging diagnosis of human Taenia Saginata infection is here presented: during COVID-19 pandemic we performed a mininvasive robotic subtotal gastrectomy for gastric angulus adenocarcinoma. 10 h after the end of the operation the patient presented an episode of vomiting with expulsion of a 5-meter-long adult form of Taenia Saginata. DISCUSSION: Parasitic infections are more frequent in the developing countries; in our case the transposition of small intestinal loop surely promoted the migration of Taenia Saginata through the gastro-jejunal anastomosis into the gastric stump.Preoperative evaluation (history, physical examination and imaging features) led to gastric cancer diagnosis and hindered the recognition of the taeniasis because of similar clinical presentations and the need to start quickly a therapeutic oncological strategy. CONCLUSION: Even if these cases are exceptional especially in Western Europe, it is important to obtain a detail clinical history and exclude parasitic infection as a cause of loss of weight and gastrointesinal abnormalities.

First cases of combined full robotic partial nephrectomy and colorectal resections: Results and new perspectives.

BACKGROUND: Nowadays the robotic platform is widespread in general surgery, urology, and gynecology. Combined surgery may represent an alternative to sequential procedures and it allows the treatment, at the same time, of coexisting lesions; in this perspective, full-robotic multiorgan surgery is starting to gain interest from surgeons worldwide. METHODS: Between April and June 2019, two patients presenting with synchronous colorectal and kidney cancers underwent, respectively, full-robotic right colectomy with right partial nephrectomy and anterior rectal resection with left partial nephrectomy. Surgeries were performed by both the general surgery and urology team. RESULTS: No intraoperative complications were registered and the postoperative course was uneventful in both cases. CONCLUSIONS: Combined multiple organ surgery with full robotic technique is safe and offers oncological adequate results. A multi-team surgical pre-planning is mandatory to reduce invasiveness and operative time. To the best of our knowledge, these are the first reports of full robotic partial nephrectomy combined with colorectal procedures.

Evolution Strategies in Transaxillary Robotic Thyroidectomy: Considerations on the First 449 Cases Performed.

BACKGROUND: In the past 20 years, the fast spread of new surgical technologies has reached an important peak with the advent of the robotic surgery. Many studies have been run about a cosmetic desire to avoid neck scars after thyroid surgery and this has led to the development of remote access robotic thyroidectomy (RT). Among the various RT approaches, unilateral transaxillary access is one of the most widely used, reporting excellent results in terms of feasibility and patient's compliance. The mini-invasive technique demonstrated many potential shortcoming overcomes with the robotic approach. At our institution a team of 3 skilled endocrine surgeons with experience in laparoscopic and robotic procedures performed RT. Our aim is to report our 8-year single-centre robot-assisted thyroidectomy experience, by applying a gasless unilateral transaxillary approach with the so-called hybrid technique, and to demonstrate its safety and feasibility. METHODS: In the period between September 2010 and June 2018 at our institution, a total of 472 patients underwent thyroid and parathyroid transaxillary surgery. The hybrid technique was applied for all the robotic procedures. A total of 412 procedures were performed with the use of external "Modena Retractor" (CEATEC® Medizintechnik) and with 3 surgeons. According to international guidelines, our indications for robotic surgery were benign lesions with a diameter <5 cm, Graves' disease, well-differentiated thyroid cancers, and parathyroid adenomas. RESULTS: In this series, a total of 449 cases were registered. General data of patients were analyzed: gender, age, body mass index, tumor size, preoperative fine-needle aspiration examination, definitive histological examination, operative time, and postoperative complications. CONCLUSIONS: This study confirms the application of robotic approach in thyroid surgery as a feasible technique in terms of safety and complications risk. The hybrid technique, together with a dedicated surgical team, can lead to obtaining the same outcomes of traditional anterior cervicotomic surgery, adding a scarless thyroidectomy.

Advances in Robotic Transaxillary Thyroidectomy in Europe.

PURPOSE OF REVIEW: The robotic surgical approach for minimally invasive thyroid surgery has been well described from the Korean surgeons and shows a wide spread diffusion in Asian area. This paper gives a systematic review aiming to pointed out the interest and the way of behaving of the European surgeons about the role of the robotic thyroidectomy (RT). RECENT FINDINGS: A literature search was performed using Pubmed, MEDLINE, Cochrane and ClinicalTrials.gov databases, including only papers wrote from european surgeons enrolling patients operated in Europe. Outcomes of interest included patients characteristics, patients position, surgical devices, surgical technique, surgical outcomes, and complications. Eighteen studies have been included in the analysis, published from 2011 to 2017. An overall number of 1108 patients were treated in studies included. In the 44.4% of studies (eight trials), the Kuppersmith position was chosen, whereas in the 22.2% (four trials), the Chung position was selected, with a mean length on axilla skin incision of 5.8 ± 1.5 cm. Considering the characteristics of the surgical technique, the mean total surgical time was 166.8 ± 36.6 min (including total thyroidectomy and loboisthmectomy together), divided three consecutive phases, such as mean working space was 50.7 ± 21.8 min, mean docking time 16.0 ± 11.9 min and mean console time 102.87 ± 38.8 min. Considering the complications, only 50% of studies included reported data about acute complications. In particular, the most frequent was hypocalcemia, occurring in 32 cases (2.9%). RLN palsy occurred in 29 patients (2.6%), definitive in 13.8% of these cases and transient in 86.2%. Only nine studies reported the discharge time, with a mean of 2.4 ± 1.2 days after surgery. SUMMARY: Despite the papers included in the study show a different way of collecting data, the transaxillary approach for robotic thyroidectomy for European patients is both feasible and safe. This procedure has to be carried out by surgeons expert in thyroid surgery with knowledge in robotic procedure. In the future, the incoming of dedicated instruments could improve and developed this technique.

Zenker diverticulectomy: first report of robot-assisted transaxillary approach.

Standard surgical treatment of Zenker's diverticulum consists of open cricopharyngeal myotomy with diverticulectomy. A rigid or flexible endoscopic approach allowing a cricopharyngeal myotomy without diverticulectomy is currently considered as a less invasive alternative to open surgery with reportedly comparable symptom relief at short term follow-up. In recent years, high safety and efficacy of a transaxillary gasless robotic access to the thyroid gland has been shown. The present study describes the feasibility and preliminary results of robot-assisted transaxillary approach for cricopharyngeal myotomy and excision of Zenker's diverticulum. Patients with troublesome dysphagia and radiological evidence of Zenker's diverticulum underwent a robot-assisted cricopharyngeal myotomy and diverticulum excision using left transaxillary access with the support of endoscopic assistance. One month after intervention, symptoms were reevaluated and a barium swallow study was performed. Four patients with symptomatic Zenker's diverticulum were successfully operated. No adverse event was recorded. One month after intervention, total dysphagia remission was declared by all four patients and there was no evidence of diverticulum recurrence at radiology. According to our preliminary data, left transaxillary robot-assisted approach for the surgical management of Zenker's diverticulum is feasible, safe and effective. Whether our encouraging results will be confirmed in larger patient cohorts with prolonged follow-up, the robot-assisted transaxillary Zenker's diverticulectomy may represent an alternative to traditional open diverticulectomy when endoscopic interventions cannot be performed or have failed.
