Para-aortic staging is sometimes a standard feature in the management of pelvic cancers. Minimal invasive approach is recommended. Several routes are possible: extra-peritoneal or intraperitoneal depending on the expertise of the surgeon. We performed several extraperitoneal para-aortic lymphadenectomy using the Da Vinci Xi robotic system through single-site incision. We have developed a step-by-step guide from patient installation, installation of the Gelpoint V monotrocar, docking of the robot arms, to surgery, with the aim of performing the most efficient and safest procedure. The surgery does not differ from standard laparoscopic extraperitoneal lymphadenectomy. The advantages of minimally invasive robotic surgery in this indication are comparable to those of the standard laparoscopy approach. But through single-site incision, the Da Vinci Xi robot improves video quality, plus its wristed tools facilitates movements compared to conventional laparoscopy.

Aims: To determine the optimal extent of lymph node dissection for non-metastatic colon cancer by tumor location based on the therapeutic value index (TVI) for each lymph node station.
Methods: Consecutive patients with surgical stage I-III colon or rectosigmoid cancer in the Japanese Society for Cancer of the Colon and Rectum database who underwent curative resection between January 2003 and December 2014 were analyzed. The TVI was defined as the incidence of lymph node metastasis multiplied by 5-year overall survival and calculated for each nodal station stratified by tumor location.

Objective: To evaluate the feasibility, safety, and quality of a standardized technique for single-port laparoscopic paraaortic lymphadenectomy guided by a novel anatomical concept.
Methods: This single-center prospective study enrolled patients with gynecological cancers requiring paraaortic lymphadenectomy from February 2022 to May 2025. All patients underwent single-port laparoscopic paraaortic lymphadenectomy using a standardized technique grounded in a novel "renal vein angle" anatomical concept.

Rationale: Struma ovarii is a rare form of mature cystic teratoma, with malignant transformation reported in approximately 5% to 10% of cases. Transformation into follicular thyroid carcinoma (FTC) is extremely uncommon; as a result, no standardized guidelines exist for treatment or prognosis for such cases.
Patient Concerns: A 54-year-old woman with cholelithiasis presented with upper abdominal discomfort.

Objective: Chylous ascites (CA) is a rare yet clinically significant complication following gynecologic cancer surgery, with incidence rates of 0.17 % to 9%. We aimed to describe a case of CA with a delayed clinical presentation nearly 100 days postoperatively in a patient with advanced endometrial cancer and to review the management strategies.
