RESUMO
BACKGROUND: Multiquadrant procedures are technically more demanding than sequential operations. The new single port (SP) system allows to work in every abdominal quadrant maintaining an adequate triangulation without the need for changes in the port positioning. METHODS: In February 2020, two patients underwent a robotic SP partial nephrectomy for malignancy combined with a cholecystectomy and a left inguinal hernia repair respectively. RESULTS: Both procedures were successfully completed with one robotic docking and without the need for conversion. The operative time was 213 minutes for the right partial nephrectomy (126 min) with cholecystectomy (18 min), and 257 minutes for the left partial nephrectomy (161 min) with inguinal hernia repair (35 min). Estimated blood loss was 200 (150-250) mL, while the total warm ischemia time was 15 minutes for the right partial nephrectomy and 53 minutes for the left partial nephrectomy. There were no intraoperative complications or perioperative transfusions. The postoperative course was uneventful, and the postoperative hospital stay was 1 and 2 days. Both resections had free margins and the median tumor size was 2.5 (1.5-3.5) cm. Histopathology analysis revealed chronic cholecystitis and renal cell carcinomas with free margins and a median tumor size of 2.5 (1.5-3.5) cm. After a mean follow-up of 24 months, no surgical-related complications or recurrence were detected. CONCLUSIONS: The robotic SP approach facilitates the completion of combined surgical procedures in multiple abdominal quadrants through a single 25mm incision.

Splenomegaly represents a challenge during splenectomy. Despite the laparoscopic approach becoming the gold standard for spleen removal, it remains controversial in this condition since the limited working space and increased risk of bleeding portray the leading causes of conversion, preventing patients from experiencing the benefits of minimally invasive surgery. The robotic platform was used to perform a splenectomy on a 55-year-old female with severe thrombocytopenia due to a relapsed large B cell lymphoma with splenomegaly. The advantages of this approach, favoring less blood loss and precise movements in a small surgical field, may allow MIS to become the first choice in this unfavorable setting, even in hematologic malignancies, which are associated with higher complication rates.
RESUMO
Pancreatic adenocarcinoma (PDAC) is one of the most common and lethal human cancers worldwide. Surgery followed by adjuvant chemotherapy offers the best chance of a long-term survival for patients with PDAC, although only approximately 20% of the patients have resectable tumors when diagnosed. Neoadjuvant chemotherapy (NACT) is recommended for borderline resectable pancreatic cancer. Several studies have investigated the role of NACT in treating resectable tumors based on the recent advances in PDAC biology, as NACT provides the potential benefit of selecting patients with favorable tumor biology and controls potential micro-metastases in high-risk patients with resectable PDAC. In such challenging cases, new potential tools, such as ct-DNA and molecular targeted therapy, are emerging as novel therapeutic options that may improve old paradigms. This review aims to summarize the current evidence regarding the role of NACT in treating non-metastatic pancreatic cancer while focusing on future perspectives in light of recent evidence.
RESUMO
Major bile duct injuries (BDIs) may require complex surgical repairs that are usually performed with a conventional open approach. This study aims to analyze current evidence concerning the safety and the outcomes of the minimally invasive (MI) approach for biliary anastomosis in post-cholecystectomy BDIs. A systematic search of MEDLINE, Embase, and Web-Of-Science indexed studies involving MI (laparoscopic or robotic) biliary anastomosis in patients with iatrogenic BDIs was performed. The quality of the studies was assessed using the MINORS criteria. A total of 13 studies involving 198 patients were included. One hundred and twenty-five patients (63.1%) underwent a laparoscopic biliary anastomosis, while 73 (36.1%) received an analogue robotic procedure. All the included BDIs were types D and E (E1-E5). The mean OT varied between 190 and 330 (mean = 227) minutes. Ten studies reported the mean intraoperative blood loss that ranged between 50 and 252 (mean = 135.9) mL. No conversions occurred in the robotic series, while four patients required conversion to open surgery among the laparoscopic ones. The mean length of postoperative hospital stay was 6.3 days. The reported overall morbidity was similar among the robotic and laparoscopic series. During the follow-up period, no surgery-related mortality occurred. A growing number of referral centers are showing the safety and feasibility of the MI approach for biliary anastomosis in patients with major BDIs. Further prospective comparative studies are needed to draw more definitive conclusions.

Length of stay after bariatric surgery has progressively shortened. Same-day discharge (SDD) has been reported for the 2 most common bariatric procedures, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). The aim of this study is to evaluate the safety and success of SDD following SG and RYGB. Systematic literature search on SDD after bariatric surgery was conducted in Medline, Cochrane library, Google Scholar, and Embase. SDD was defined as discharging the patient during the day of the bariatric operation, without an overnight stay. The primary outcomes of interest were successful SDD, readmission, and morbidity rates. The secondary endpoints included reoperation and mortality rates. A proportion meta-analysis was performed to assess the outcomes of interest. A total of 14 studies with 33,403 patients who underwent SDD SG (32,165) or RYGB (1238) were included in the qualitative synthesis. Seven studies with 5000 patients who underwent SDD SG were included in the quantitative analysis, and pooled proportions (PPs) were calculated for the outcomes of interest. The SDD success rate was 63%-100% (PP: 99%) after SG and 88%-98.1% after RYGB. The readmission rate ranged from .6% to 20.8% (PP: 4%) after SDD SG and 2.4%-4% after SDD RYGB. Overall morbidity, reoperation, and mortality were 1.1%-10% (PP:4%), .3%-2.1% (PP: 1%), and 0%-.1% (PP: 0%), respectively, for SDD SG, and 2.5%-4%,1.9%-2.5%, and 0%-.9%, respectively, for SDD RYGB. SDD after SG seems feasible and safe. The outcomes of SDDRYGB seem promising, but the evidenceis stilllimitedto draw definitive conclusions. Selection criteria and perioperative protocolsmust be standardized to adequately introduce this practice.

BACKGROUND: The utilization of the robot for inguinal hernia repairs has increased in the past years. The new Da Vinci Single Port (SP) system provides the benefits of single-incision procedures and might overcome the technical difficulties of previous single-incision techniques. The aim of this study was to evaluate the safety and feasibility of the SP transabdominal preperitoneal inguinal hernia repair (SP-TAPP) and compare its outcomes to the robotic multiport technique (MP-TAPP). METHODS: A prospective cohort of patients who underwent a robotic SP-TAPP and MP-TAPP between 2012 and 2022 was analyzed. Primary endpoints were same-day discharge, morbidity, and inguinal recurrence rates. Secondary endpoints included conversion, operative time, port-site incisional hernia, and chronic pain. RESULTS: MP-TAPP and SP-TAPP were performed in 378 (81.3%) and 87 (18.7%) patients, respectively. Demographics were similar between groups. There were no conversions or intraoperative complications. Mean operative (MP-TAPP: 93.2 vs. SP-TAPP: 78.1 min, p = 0.003) and recovery time (MP-TAPP: 160.8 vs SP-TAPP: 112.6 min, p < 0.001) were significantly shorter in the SP group. Same-day discharge rate was higher (MP-TAPP: 86.5% vs. SP-TAPP: 97.7%, p = 0.001) after SP-TAPP; 30-day morbidity, readmissions, and chronic pain rates were similar between groups. After a mean follow-up of 30.6 months for MP-TAPP and 13.3 months for SP-TAPP, inguinal hernia recurrence and port-site incisional rates were similar between groups. CONCLUSION: Robotic SP-TAPP is safe and feasible. When compared to MP-TAPP, it showed similar postoperative morbidity, higher same-day discharge rates, and a quicker postoperative recovery. Further studies are needed to confirm the benefits of the SP platform.

PURPOSE: Same-day discharge (SDD) after bariatric surgery is gaining popularity. We aimed to analyze the safety of SDD after Roux-en-Y gastric bypass (RYGB) and compare its outcomes to inpatients discharged on postoperative days 1-2. MATERIALS AND METHODS: We performed a retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database for the period 2015-2020. Patients who underwent primary laparoscopic RYGB and were discharged the same day of the operation (SDD-RYGB) and inpatients discharged on postoperative days 1-2 (In-RYGB) were compared. Primary outcomes of interest were overall morbidity, serious morbidity, readmission, reoperation, intervention, and mortality rates. RESULTS: A total of 167,188 patients were included; 2156 (1.3%) SDD-RYGB and 165,032 (98.7%) In-RYGB. Mean age (SDD-RYGB: 44.5 vs. In-RYGB: 44.6 years), proportion of females (SDD-RYGB: 81.4% vs. In-RYGB: 80.6%), and mean body mass index (SDD-RYGB: 45.8 vs. In-RYGB: 45.9 kg/m2) were similar between groups. Overall morbidity (SDD-RYGB: 11.3% vs. In-RYGB: 10.2%; OR: 1.2, p = 0.08), serious morbidity (SDD-RYGB: 3.1% vs. In-RYGB: 3%; OR: 1.03, p = 0.81), reoperation (SDD-RYGB: 1.4% vs. In-RYGB: 1.2%; OR: 1.16, p = 0.42), readmission (SDD-RYGB: 4.8% vs. In-RYGB: 4.8%; OR: 1.01, p = 0.89), and mortality (SDD-RYGB: 0.04% vs. In-RYGB: 0.09%; OR: 0.53, p = 0.53) were comparable between groups. SDD-RYGB had lower risk of 30-day interventions (SDD-RYGB: 1.1% vs. In-RYGB: 1.6%; OR: 0.64, p = 0.04) compared to In-RYGB. CONCLUSION: Same-day discharge after RYGB seems to be safe and has comparable outcomes to admitted patients. Standardized patient selection criteria and perioperative management protocols are needed to further increase the safety of this practice.

Pancreatic neuroendocrine tumors (pNETs) represent the leading cause of disease-specific mortality in patients with Multiple Neuroendocrine Neoplasia type 1 (MEN1). Although surgery is the recommended treatment for non-functional pNETs >2 cm, the management of recurrent lesions between 1 and 2 cm is controversial. Robotic surgery was used on a 29-year-old female with MEN1 and previous distal splenopancreatectomy that presented with a 1 cm recurrent pNET. The advantages offered by this approach facilitating a precise resection of the tumor and minimizing the postoperative morbidity may favor the decision towards redo surgery for local recurrences <2 cm, expanding current indications.
RESUMO
BACKGROUND: We aim to analyse the safety and feasibility of the DaVinci Single Port (SP) platform in general surgery. METHODS: A prospective series of robotic SP transabdominal pre-peritoneal inguinal hernia repairs (SP-TAPP) and cholecystectomies (SP-C) (off-label) were analysed. Primary endpoints were safety and feasibility defined by the need for conversion and incidence of perioperative complications. RESULTS: A total of 225 SP procedures were performed; 84 (37.3%) SP-TAPP (70 unilateral, 7 bilateral), and 141 (62.7%) SP-C. There were no conversions or additional ports placed. Mean console time was 17.6, 31.9, and 54 min for SP-C, unilateral, and bilateral SP-TAPP, respectively. There was no mortality, intraoperative or major postoperative complications. Mean LOS was 2.7 h for elective SP-TAPP and 2.3 h for SP-C. CONCLUSION: Robotic SP surgery is safe and feasible for two of the most performed general surgery operations. Further experience might allow expanding the applications of robotic single-incision surgery for other procedures.

Chronic pancreatitis is a benign inflammatory disorder, which can lead to severe and persistent symptoms. Patients with recurrent episodes of abdominal pain often require endoscopic treatments, which are frequently associated with inadequate symptom relief. In selected patients, surgical treatment allows for a greater long-term pain reduction.As one of the first teams reporting this approach, we present a didactical video with a stepwise technique to perform a robotic Puestow procedure.This technical report details a robotic approach to complete a latero-lateral pancreatojejunostomy in patients with symptomatic chronic pancreatitis with dilated main pancreatic duct.The robotic approach has shown to be an effective treatment with postoperative relief of ductal hypertension and successful long-term outcomes in patients with symptomatic chronic pancreatitis. A properly executed operation following precise surgical steps is critical for the success of the procedure.

INTRODUCTION: To date, no anti-reflux operations have been reported with the new da Vinci Single-Port (single port (SP)) robotic platform. We aimed to describe this novel surgical approach and evaluate its safety and feasibility. METHODS: All robotic SP operations were performed under an Institutional Review Board approved protocol. RESULTS: Two patients underwent robotic SP anti-reflux surgery through a single incision of 2.7 cm (one Nissen-fundoplication and one re-Redo Nissen-fundoplication). The mean docking-time was 2.5 (2-3) minutes and mean console-time was 147 (119-155) minutes. No additional ports were needed, and no intraoperative complications occurred. Patients tolerated a soft diet on postoperative day 1 and were discharged on POD-2 and 3. CONCLUSION: Robotic SP anti-reflux surgery appears to be safe and feasible. This platform offers similar advantages to the multiport robotic surgery, while adding lower invasiveness and an improved cosmesis. Further studies are needed to confirm our results and evaluate long-term outcomes of this surgical approach.

BACKGROUND: Despite the high success rate associated with Heller myotomy in the treatment of primary achalasia, symptom persistence or relapse occurs in approximately 10-20% of patients. Unfortunately, the ideal treatment after failed myotomy is not well established yet. We present a didactical video with a stepwise technique to perform a robotic revisional procedure after failed Heller myotomy. METHODS: In this report, each surgical step is thoroughly described and visually represented with useful technical tips that might help in improving surgical results of revisional Heller myotomy. RESULTS: In patients with previous surgical myotomy, the robotic platform with its high-definition magnified view and EndoWrist instruments allow for a safe and precise redo surgical myotomy. CONCLUSIONS: Despite its improved surgical capabilities, the role of robotic redo Heller myotomy in the treatment algorithm of patients with recurrent symptoms after failed surgical myotomy should be further explored.

Bariatric surgery has been demonstrated to be effective in achieving significant weight loss and remission of obesity-related comorbidities. However, a percentage of patients fail to lose enough weight, regain weight, or experience postoperative complications, requiring additional interventions. Revisional bariatric surgeries (RBS) involve the wide spectrum of procedures that aim to treat complications of the index operation or achieve further weight loss. These are technically challenging procedures due to adhesions of the internal organs, reduced working space, and a distorted anatomy. Indications, timing, and type of operation for RBS are not standardized, and there is no consensus on the best surgical approach. Some authors claim a robotic platform could be advantageous in these types of procedures that are performed in reduced, deep operating fields, or those requiring precision and accuracy. This review examines the most current and representative literature on the outcomes of robot-assisted RBS. Included studies demonstrate the safety and feasibility of the robotic approach for RBS. However, long operative times and high costs remain major drawbacks of the device. Finally, if we consider that many centers have not yet completed the learning curve for robot-assisted RBS, the potential for improved outcomes seems promising.
RESUMO
Background: With the rising number of bariatric surgeries performed annually, there has also been an increase in revisional bariatric surgeries (RBS). The aim of this study is to evaluate the safety and postoperative outcomes of RBS performed with a minimally invasive approach. Methods: Retrospective analysis on a prospectively collected database of patients who underwent minimally invasive RBS between 2012 and 2019. Primary endpoints were conversion rate, major morbidity, mortality, and 30-day reoperation rate. Comparative analysis of laparoscopic adjustable gastric banding (LAGB) conversion to sleeve gastrectomy (SG) vs. conversion to Roux-en-Y gastric bypass (RYGB) was performed. Results: A total of 221 patients underwent minimally invasive RBS, 137 (62%) laparoscopically and 84 (38%) robotically. The most common RBS were LAGB to SG (59.3%) and LAGB to RYGB conversions (16.7%). The main indication was weight loss failure (88.7%). Conversion rate, major morbidity, and mortality were 0.9, 3.2, and 0.4%, respectively. Urgent reoperation was required in 3.2% of cases. Total weight loss at 1 and 2-years follow- were 14.3 and 17.3%, respectively. Comparative analysis of LAGB conversion to SG vs. RYGB showed similar major morbidity (SG: 2.3% vs. RYGB 0%, p = 1). Greater total weight loss was achieved in LAGB to RYGB conversions at 1-year (SG: 14.8% vs. RYGB 25.3%, p < 0.001). Conclusions: Minimally invasive RBS can be performed safely in a broad patient population with low conversion and complication rates, and improved weight loss outcomes. LAGB to RYGB conversions are associated with greater weight loss. Further randomized trials are needed to draw more conclusive recommendations.
RESUMO
BACKGROUND: Centrally located pancreatic lesions are often treated with extended pancreaticoduodenectomy or distal pancreatectomy resulting in loss of healthy parenchyma and a high risk of diabetes and exocrine insufficiency. Robotic central pancreatectomy (RCP) is a parenchyma sparring alternative that has been shown safe and feasible [1,2]. METHODS: In this article, we describe our operative technique and the perioperative outcomes of a series of RCP for low-grade or benign pancreatic tumors. RESULTS: Six patients (5 female and 1 man) with a median age of 51.5 (44-68) years underwent a RCP for 2 serous cystadenomas, 2 mucinous cystic tumors, 1 neuroendocrine tumor, and 1 autoimmune pancreatitis. There were no conversions, intraoperative complications, or perioperative transfusions. Median operative time and was 240 (230-291) minutes and median blood loss was 100 (100-400) ml. The median hospital stay was 8 (5-27) days. There were no mortalities, reoperations, or readmissions. One patient developed a grade B pancreatic fistula which was successfully managed conservatively. All resections had free margins and the median tumor size was 2.5 (1.5-3.5) cm. After a mean follow-up of 46 months, no patients presented new-onset diabetes or exocrine insufficiency. CONCLUSIONS: RCP represents the least invasive option for both the patient and the pancreatic parenchyma. With a standardized technique, RCP results in low postoperative morbidity and excellent long-term pancreatic function. Although our results are excellent, POPF still represents the main complication of central pancreatectomy with an incidence ranging from 0 to 80% depending on multiple factors such as the surgeon, technique, and pancreatic texture.

BACKGROUND: Minimally invasive resection of gastrointestinal stromal tumors (GIST) results in faster recovery and similar oncological safety when compared to conventional approach [1-3]. The new robotic Single Port platform (Da Vinci SP) could help decreasing invasiveness while overcoming technical limitations of previous single incision surgical approaches [4]. METHODS: A 69-year-old male was treated for a 3 cm non-ulcerated GIST in the anterior wall of the proximal gastric body. RESULTS: A robotic partial gastric resection was performed. The Da Vinci SP platform, which hosts three multi jointed, wristed instruments and a 3D HD articulating scope was used. The camera and instruments were introduced in the abdominal cavity through a 25 mm multichannel port. The lesion was identified in the lesser curvature at the level of the body, approximately 3 cm above the incisura. The gastric wall was resected en-bloc with the tumor using a combination of monopolar hook and bipolar forceps. The lesion was lifted using the third robotic arm and was not manipulated during the dissection. The gastric defect was closed with two running sutures of polydioxanone 3/0. Operative time was 82 minutes. Postoperative course was uneventful, and the patient was discharged home on postoperative day 2 with adequate pain control. Histopathology analysis found a 2.3 × 2 cm low grade GIST. CONCLUSIONS: Robotic SP partial gastrectomy is safe and feasible in patients with gastric GIST. The robotic SP approach might help expanding the indications of previous single incision techniques.

BACKGROUND: Same-day discharge after sleeve gastrectomy (SG) is gaining popularity. We aimed to determine risk factors associated with readmission in patients who underwent same-day discharge SG. METHODS: We performed a retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database for the period 2015-2018. Patients who underwent SG and were discharged the same day of the operation were included in the analysis. Multivariable logistic regression analysis was performed to determine risk factors for readmission. RESULTS: A total of 466,270 SG were performed during the study period; 14,624 (3.1%) patients were discharged the same day and were included in the analysis. Mean age was 43.4 (14.7-80) years and 11,718 (80.1%) were female. Mean preoperative BMI was 43.7 ± 7.4 kg/m2. Mean operative time was 58.3 ± 32.4 min. Thirty-day reoperation, reintervention, and mortality rates were 0.7%, 0.7%, and 0.1%, respectively. Readmission rates were similar in same-day discharge and inpatient SG (2.9% vs. 3%, p = 0.5). Female sex (OR 1.52, 95% CI 1.15-2.00), preoperative gastroesophageal reflux disease (OR 1.33, 95% CI 1.08-1.64), renal insufficiency (OR 3.06, 95% CI 1.01-9.32), and intraoperative drain placement (OR 1.78, 95% CI 1.37-2.31) were independent risk factors for readmission following same-day discharge SG. CONCLUSIONS: Same-day discharge SG appears to be safe and is associated with low readmission rates. However, the identification of preoperative and intraoperative variables associated with higher risk of readmission might help defining safer and more effective same-day discharge protocols.
