Background: Isolated pancreatic metastasis from melanoma is extremely uncommon and accounts for approximately only 2% of visceral disseminations of melanoma. 1-3 Interestingly, pancreatic localizations disproportionately derive from primary ocular melanoma. 1,2 Despite the currently available evidence on this argument being scarce, the survival outcomes of patients receiving resection for visceral melanoma metastases are reported to be superior than those managed by non-surgical modalities. 4,5 CASE PRESENTATION: A 59-year-old female with a history of uveal melanoma presented with surveillance-detected metastatic disease confined to the pancreas. Computed tomography demonstrated one lesion located in the body of the pancreas and one further lesion in the head. The presented video illustrates the details of an extended, ultrasound-guided, robotic distal pancreatectomy., Discussion: Metastatic ocular melanoma has a highly variable natural history, which ranges from a fulminant course to prolonged stable disease. 6 In contrast to cutaneous melanoma derivation, metastases mostly occur via hematogenous spread, in the absence of lymphatic drainage of the eye. 6,7 Liver is the most common site of secondary localization and is not involved by metastatic disease in <10% of cases. Interestingly, patients with extrahepatic metastases tend to have significantly better survival rates than those with hepatic disease. 6,7 Fewer than 100 cases of pancreatic metastasis from malignant melanoma are reported in the medical literature, including a relatively high percentage of primary ocular malignancies. 1,5 Furthermore, the prognosis of these patients is essentially unknown, although metastatic melanoma of both cutaneous and ocular origin generally indicates poor survival. 1,5,6 Although no robust evidence is available, a number of reports suggest that pancreatic resection may improve survival in these patients. 1-4 A large retrospective review investigating the association between treatment modalities and survival of patients with abdominal visceral melanoma metastases showed that patients receiving resection had a superior median survival compared with patients treated medically. Although patients with metastases of the gastrointestinal tract showed the best outcomes following surgery, patients with pancreas metastasis (of both cutaneous and ocular origin) undergoing resection also exhibited a significant survival advantage compared with those treated non-surgically. 5 Minimally invasive pancreatectomy is gaining momentum. 8 In fact, in selected patients there are distinct advantages compared with conventional surgery owing to reduced postoperative morbidity and earlier return to daily activities, while maintaining the oncological tenets of resection. 8-10 Recent reports suggest that the application of robots may provide some advantages over conventional laparoscopy, especially for patients necessitating technically challenging surgeries. 8,11 Such benefits are mainly in relation to the rate of conversion, length of postoperative hospital stay, and number of cases necessary to surmount the learning curve and reach optimal performance; however, no definitive conclusions can be drawn due to the lack of high-level evidence. 8,10 ., (© 2021.

Purpose: The objective of this study was to investigate the risk of conversion associated with conventional laparoscopic surgery (LAP) versus robot-assisted surgery (ROB) in patients undergoing abdominal oncological surgery. Possible differences between ROB and LAP on postoperative overall and major morbidity, operative time, and length of hospitalization were also assessed., Methods: We included randomized controlled trials of LAP versus ROB surgery in patients with abdominal malignancy. We searched PubMed, EMBASE, and the Central registries through September 2020. Risk of bias was estimated concerning randomization, allocation sequence concealment, blinding, incomplete outcome data, selective outcome reporting, and other biases., Results: A total of 1867 patients from 12 trials were included in this review. The rate of conversion was significantly higher for LAP than for ROB patients (10 trials, 1447 participants, p = 0.03, OR = 0.56 [0.33, 0.95]). There was a nonsignificant advantage of ROB over LAP on the rate of overall postoperative morbidity (12 trials, 1867 participants, p = 0.32, OR = 0.83) and major morbidity (7 trials, 792 participants, p = 0.87, OR= 0.93). ROB was also associated with prolonged operative time and abbreviated postoperative hospitalization as compared to LAP (p = 0.002, MD = 27.87, and p = 0.04, MD = -0.57, respectively)., Conclusions: According to the available highest level of evidence, the application of ROB decreases the incidence of unplanned conversion into an open procedure as compared to standard LAP in the setting of oncological minimally invasive surgery.

Minimally invasive surgery has gained worldwide acceptance in the treatment of colonic cancer in the last decades, thanks to its well-known advantages in short-term outcomes. Nevertheless, the penetrance of minimally invasive colorectal surgery still remains low. Few studies and metanalysis, to date, have analyzed the results of robotic versus laparoscopic colorectal surgery, often with conflicting conclusions. The robotic platform, thanks to its technological features, may potentially overcome the limitation of standard laparoscopy, especially when performing a complete mesocolic excision resection and an intracorporeal anastomosis. Robotic surgery could also shorten the learning curve of young novice surgeons, provided that strict protocols of structured training are applied. This paper is an update on the current available outcomes of robotic vs laparoscopic surgery in right colectomy.

Background: The adoption of robotic surgery for esophageal cancer has been expanding rapidly over the recent years. In the setting of two-field esophagectomy, different techniques exist for intrathoracic esophagogastric anastomosis, although the superiority of one over another has not been clearly demonstrated. Potential benefits in terms of anastomotic leakage and stenosis have been reported in association with a linear-stapled anastomosis as compared to the more widespread techniques of circular mechanical and hand-sewn reconstructions, however, there is still limited reported evidence on its application to robotic surgery. We here report our fully robotic technique of side-to-side, semi-mechanical anastomosis. Methods: All consecutive patients undergoing fully robotic esophagectomy featuring intrathoracic side-to-side stapled anastomosis by a single surgical team were included in this analysis. Operative technique is detailed, and perioperative data are assessed. Results: A total of 49 patients were included. There were no intraoperative complications and no conversion occurred. The rate of overall postoperative morbidity was 25, 14% being the relative rate of major complications. With anastomotic-related morbidity in particular, one patient developed minor anastomotic leakage. Conclusions: Our experience demonstrates that a linear, side-to-side fully robotic stapled anastomosis can be created with a high technical success and minimal incidence of anastomosis-related morbidity.

Purpose: Minimally invasive surgery has been universally accepted as a valid option for the treatment of diverticular disease, provided specific expertise is available. Over the last decade, there has been a growing interest in the application of robotic approaches for diverticular disease. We aimed at evaluating whether robotic colectomy may offer some advantages over the laparoscopic approach for surgical treatment of diverticular disease by meta-analyzing the available data from the medical literature. Methods: The PubMed/Medline, EMBASE, and Web Of Sciences electronic databases were searched for literature up to December 2020. Inclusion criteria considered all comparative studies evaluating robotic versus laparoscopic colectomy for diverticulitis eligible. The conversion rate to the open approach was evaluated as the primary outcome. Results: The data of 4177 patients from nine studies were included in the analysis. There were no significant differences in the baseline characteristics. Patients undergoing laparoscopic colectomy compared to those who underwent surgery with a robotic approach had a significantly higher risk of conversion into an open procedure (12.5% vs. 7.4%, p < 0.00001) and abbreviated hospital stay (p < 0.0001) at the price of a longer operating time (p < 0.00001). Conclusion: Compared with conventional laparoscopic surgery, the robotic approach offers significant advantages in terms of conversion rate and shortened hospital stay for the treatment of diverticular disease. However, because of the lack of available evidence, it is impossible to draw definitive conclusions. [ABSTRACT FROM AUTHOR]

Background. Minimally invasive gastrectomy is currently considered a valid option to treat gastric cancer and is gaining increasing acceptance. Recent reports have suggested that the application of robots may confer some advantages over conventional laparoscopy, but the role of robotic surgery in clinical practice is still uncertain. We aimed to critically review the relevant evidence comparing robotic to standard laparoscopic surgery in performing radical gastrectomy. Methods. The Pubmed/Medline electronic databases were searched through February 2021. Paper conference and the English language was the only restriction applied to our search strategy. Results. According to the existing data, robotic gastrectomy seems to provide some benefits in terms of blood loss, rate of conversion, procedure-specific postoperative morbidity, and length of hospital stay. Robotic gastrectomy is also associated with a longer duration of surgery and a higher economic burden as compared to its laparoscopic counterpart. No significant differences have been disclosed in terms of long-term survivals, while the number of lymph nodes retrieved with robotic gastrectomy is generally higher than that of laparoscopy. Conclusions. The current literature suggests that robotic radical gastrectomy appears as competent as the conventional laparoscopic procedure and may provide some clinical advantages. However, due to the relative paucity of high-level evidence, it is not possible to draw definitive conclusions. [ABSTRACT FROM AUTHOR]
