BACKGROUND: Perihilar cholangiocarcinoma, intrahepatic cholangiocarcinoma (IHCC), and gall bladder cancer are difficult malignancies to treat and are characterized by a tendency for local recurrence and a generally unfavorable prognosis. Surgical resection offers the only potential cure, conventionally performed via the open approach. Although minimally invasive approaches show promise, data remain limited.
METHODS: With the institutional review board\'s approval, we prospectively followed 100 patients between 2013 and 2023 who underwent robotic surgical resection for perihilar, IHCC, and gallbladder cholangiocarcinoma. Data are presented as median (mean ± SD). Significance was accepted at P ≤ .05.
RESULTS: The median patient age was 70 years, and the median operative duration was 333 min, with an estimated blood loss of 200 mL. Importantly, no unplanned conversions occurred, and only 1 intraoperative complication occurred within the IHCC cohort. The median length of stay was 4 days. There were a total of 19 postoperative complications and 19 readmissions within 30 days. Additionally, there were 3 in-hospital mortalities and 5 90-day mortalities. R0 resection was achieved in 87% of patients and R1 resection in 13%. At a median follow-up of 36 months, 62% of patients demonstrated disease-free survival, whereas 6% continued to live with the disease, and 32% did not survive.
CONCLUSIONS: Our experience demonstrates the feasibility and safety of robotic resection for these complex malignancies, yielding promising short-term outcomes. Further investigation is required to ascertain the long-term oncologic outcomes.

Robotic resection is widely used to treat colorectal cancer. Although the novel natural orifice specimen extraction surgery (NOSES) results in less trauma, its safety and effectiveness are relatively unknown. In the present study, we used propensity score matching to compare the effectiveness and safety of NOSES and robotic resection for treating colorectal cancer. Present retrospective cohort study included patients who underwent robotic colon and rectal cancer surgery between January 2016 and December 2019 at the Department of Gastrointestinal Surgery, the Second Xiangya Hospital of Central South University. The intraoperative time, intraoperative bleeding, postoperative recovery, postoperative complications, and survival status of the conventional robotic colorectal cancer resection (CRR) (78 patients) and NOSES (89 patients) groups were compared. These results showed that no significant differences were observed between the two groups in terms of early postoperative complications, operation time, and the number of lymph nodes dissected. Compared with the CRR group, NOSES group had shorter postoperative exhaust time [3.06 (0.76) vs. 3.53 (0.92)], earlier eating time [4.12 (1.08) vs. 4.86 (1.73)], lesser intraoperative bleeding [51.23 (26.74) vs. 67.82 (43.44)], lesser degree of pain [80.8% vs. 55.1%], and shorter length of hospital stay [8.73 (2.02) vs. 9.50 (3.45)]. All these parameters were statistically significant (P < 0.05). However, no significant differences were observed in the 3-year overall survival rate and disease-free survival rate between both groups (P > 0.05). Collectively, robotic NOSES is a safe and effective approach for treating rectal and sigmoid colon cancers, could decrease intraoperative bleeding and postoperative complications, and accelerate the speed of intestinal function recovery.

Pulmonary sleeve resection is a technically challenging procedure entailing expertise to perform via a minimally invasive approach. Robotic thoracic surgery with its three-dimensional high-definition imaging and true depth perception enables clarity of anatomical structures and, in conjunction with its articulated instruments, provides greater dexterity compared with video-assisted thoracoscopic surgery, allowing complex manoeuvres in limited spaces. We present the case of a 22-year-old woman who presented with recurrent chest infections, dyspnoea on exertion, cough, loss of appetite and weight loss. On investigation, she was diagnosed with an endobronchial neuroendocrine tumour. She underwent a robotic-assisted left upper lobe sleeve lobectomy and mediastinal lymph node dissection. The patient made a good recovery with no perioperative or postoperative complications. This case serves as an educational tool and includes instructions for excellent results.

The current gold standard for the treatment of Pancoast tumours is considered to be neoadjuvant chemoradiation followed by radical resection of the affected upper lobe en bloc with resection of the chest wall. Shaw and Paulson first described the most commonly used approach in 1961 via an extended posterolateral thoracotomy. However, because this approach comes with significant soft tissue damage and occasionally provides only suboptimal exposure, especially for anterior superior sulcus tumours, other approaches have been published in recent years, including open anterior approaches (Dartevelle and Gruenenwald) in addition to rare case reports of minimally invasive assisted hybrid procedures. Because we routinely perform robotic anatomical lung resections as well as three-port robotic first rib resections for thoracic inlet/outlet syndrome in our department, combining both techniques with our accumulated experience seemed to be the next logical step. We describe step-by-step what is (to our knowledge) one of the first reported cases of a fully portal robotic-assisted Pancoast tumour resection consisting of a left upper lobe resection en bloc with the first rib after neoadjuvant chemoradiation therapy. This approach proved to be safe and allowed for excellent exposure, especially of the thoracic outlet.

A 43-year-old man presented with a several-month history of worsening left shoulder pain. On imaging, he was found to have an osseous mass arising from his left second rib and protruding into the soft tissues of his chest. The mass had radiographic characteristics consistent with those of an osteochondroma. He had point tenderness over the mass, and the area of point tenderness was consistent with his description of the location of his pain over the past several months. Based on his symptoms, he was taken to the operating room for robotic excision of this mass. He was placed in a right lateral decubitus position, and three robotic ports were inserted. The mass was identified based on landmarks and was dissected free. The bony attachment of the mass to the second rib was transected using a Kerrison rongeur. The mass was delivered into the chest and removed using an endobag. The patient was discharged the following day after removal of his Blake drain. His pain had completely resolved at the postoperative follow-up examination, and his final pathological report confirmed the benign diagnosis of osteochondroma.

Among the various segmentectomy procedures performed for lung diseases, the right S4 segmentectomy stands out as an exceptionally rare operation. Its infrequent occurrence can be attributed to several factors, including the relatively lower incidence of pathologies necessitating isolated resection of the S4 segment of the right lung. This video tutorial showcases the robotic approach to the rare right S4 segmentectomy, guiding surgeons through the step-by-step procedures for better understanding and proficiency.

BACKGROUND: Primary hyperparathyroidism is a disease caused by the secretion of excess parathyroid hormone (PTH) owing to the enlargement of the parathyroid gland. Ectopic parathyroid glands exist in the mediastinum in approximately 1-2% of cases, which is relatively rare. Intraoperative monitoring of serum PTH level is important to assess whether the source of hyperparathyroidism has been eliminated.
METHODS: A 53-year-old asymptomatic woman was diagnosed with ectopic mediastinal parathyroid adenoma. A three-port robotic partial resection of the thymus containing the tumor was attempted, but bleeding from a swollen pericardial diaphragmatic vein led to the addition of an assist port along the way. The PTH level was measured intraoperatively. After confirming that the 15-min PTH level after removal of the tumor was less than 50% of the baseline value, the operation was completed. The tumor was positive for PTH and was diagnosed as an ectopic mediastinal parathyroid adenoma. Some small ectopic parathyroid gland tissues were observed in other parts of the thymic tissue. Serum calcium and PTH levels decreased and normalized.
CONCLUSIONS: We report the usefulness of robotic resection for ectopic mediastinal parathyroid adenoma with PTH monitoring. However, histopathologically, small parathyroid gland tissues may remain in the surrounding thymus. Hence, we believe that a strict follow-up is required for parathyroid function in the future.

BACKGROUND: The primary goal of this study was to evaluate peroperative and early postoperative results of laparoscopic and robotic surgery for rectal cancer with total mesorectal excision (TME) and with primary anastomosis.
METHODS: 404 patients were enrolled in the study, divided in two cohorts and compared retrospectively: a laparoscopic group (n=236) versus a robotic (TME + primary coloanal anastomosis) group (n=168). The evaluated cohorts were comparable in sex, age, BMI, ASA score, distal tumor margin from anal verge and neoadjuvant chemoradiotherapy. More advanced tumor stages were observed in the robotic group (p=0.009).
RESULTS: The duration of robotic resection was significantly longer compared to laparoscopic resection (p.

BACKGROUND: Experience in minimally invasive surgery in the treatment of duodenal gastrointestinal stromal tumors (DGISTs) is accumulating, but there is no consensus on the choice of surgical method.
OBJECTIVE: To summarize the technique and feasibility of robotic resection of DGISTs.
METHODS: The perioperative and demographic outcomes of a consecutive series of patients who underwent robotic resection and open resection of DGISTs between May 1, 2010 and May 1, 2020 were retrospectively analyzed. The patients were divided into the open surgery group and the robotic surgery group. Pancreatoduodenectomy (PD) or limited resection was performed based on the location of the tumour and the distance between the tumour and duodenal papilla. Age, sex, tumour location, tumour size, operation time (OT), estimated blood loss (EBL), postoperative hospital stay (PHS), tumour mitosis, postoperative risk classification, postoperative recurrence and recurrence-free survival were compared between the two groups.
RESULTS: Of the 28 patients included, 19 were male and 9 were female aged 51.3 ± 13.1 years. Limited resection was performed in 17 patients, and PD was performed in 11 patients. Eleven patients underwent open surgery, and 17 patients underwent robotic surgery. Two patients in the robotic surgery group underwent conversion to open surgery. All the tumours were R0 resected, and there was no significant difference in age, sex, tumour size, operation mode, PHS, tumour mitosis, incidence of postoperative complications, risk classification, postoperative targeted drug therapy or postoperative recurrence between the two groups (P > 0.05). OT and EBL in the robotic group were significantly different to those in the open surgery group (P < 0.05). All the patients survived during the follow-up period, and 4 patients had recurrence and metastasis. No significant difference in recurrence-free survival was noted between the open surgery group and the robotic surgery group (P > 0.05).
CONCLUSIONS: Robotic resection is safe and feasible for patients with DGISTs, and its therapeutic effect is equivalent to open surgery.

Background  Pulmonary epithelial-myoepithelial carcinoma (P-EMC) is an extremely rare, well-differentiated, and malignant neoplasm originating from submucosal bronchial glands in the lung. EMCs arise mainly in the salivary glands. Case Description  This case represents an asymptomatic 78-year-old male with a remote 75-pack-year history of smoking who presents with a solitary endobronchial lesion, which is suggestive of a primary lung EMC, detected on annual screening chest computed tomography (CT) scan. Conclusion  A recent review of literature reveals less than 50 documented cases of the pulmonary subtype of this tumor worldwide. We are reporting a unique case of robot-assisted pulmonary lobectomy for a P-EMC.
