Personalized evaluation of D3-lymph node dissection complexity for right colorectal cancer considering anatomy of superior mesenteric vessels.

Objective: To provide a personalized approach to D3 lymph node dissection (LND) in right colon cancer using a proper analysis and interpretation of CT angiography of superior mesenteric vessels.

Material And Methods: An observational cross-sectional study included 34 patients who underwent surgery for right colon cancer with D3 LND along superior mesenteric artery (SMA) and vein (SMV). Characteristics of surgically relevant vascular anatomy were evaluated as 0 or 1 depending on complexity of anatomical characteristic.

Vascular-oriented D3 lymph node dissection with left colic artery preservation for distal sigmoid colon cancer: a variety of techniques.

Background: One of the approaches to distal sigmoid colon cancer surgical treatment is segmental colonic resection with vascular preservation of left colic artery (LCA). D3 lymph node dissection may technically vary according to different vascular anatomy. This study aims to show the approaches to D3 lymph node dissection with LCA preservation for distal sigmoid colon cancer according to different patterns of inferior mesenteric artery (IMA) branching.

Advancing mid-rectal cancer surgery: Unveiling the potential of natural orifice specimen extraction surgery in comparison to conventional laparoscopic-assisted resection.

Background: Mid-rectal cancer treatment traditionally involves conventional laparoscopic-assisted resection (CLAR). This study aimed to assess the clinical and therapeutic advantages of Natural Orifice Specimen Extraction Surgery (NOSES) over CLAR.

Aims: To compare the clinical outcomes, intraoperative metrics, postoperative recovery, complications, and long-term prognosis between NOSES and CLAR groups.

Primary retroperitoneal approach for vessel-sparing D3-lymph node dissection in left colonic and rectal cancer resections - the first Russian experience.

Objective: To develop and describe a technique of primary retroperitoneal approach for vessel-sparing D3-lymph node dissection in the left colon and rectal cancer surgery; to evaluate the short-term results of the first series of patients treated with a new minimally invasive method.

Material And Methods: The first 10 patients with adenocarcinoma of the left colon and rectum, who underwent surgical treatment using the retroperitoneal approach with vessel-sparing D3 lymph node dissection, were included in the study. The primary retroperitoneal approach involved mobilization of the left side of the colon, D3 lymph node dissection with skeletonization of inferior mesenteric artery (IMA) and selective ligation of afferent vessels from retroperitoneal space using SILS access system at the first steps of surgery.

Selective approach to arterial ligation in radical sigmoid colon cancer surgery with D3 lymph node dissection: A multicenter comparative study.

Objectives: Radical surgery for sigmoid colon cancer is commonly performed with complete mesocolic excision (CME) and apical lymph node dissection, reached by central vascular ligation (CVL) of the inferior mesenteric artery (IMA) and associated extended left colon resection. However, IMA branches can be ligated selectively according to tumor location with D3 lymph node dissection (LND), economic segmental colon resection and tumorspecific mesocolon excision (TSME) if IMA is skeletonized. This study aimed to compare left hemicolectomy with CME and CVL and segmental colon resection with selective vascular ligation (SVL) and D3 LND.

Surgeon's role in CT-based preoperative determination of inferior mesenteric artery anatomy in colorectal cancer treatment.

Background: The inferior mesenteric artery (IMA) is a blood vessel of great importance in left colon and rectal cancer surgery. We aimed to determine the role of surgeons in computed tomography (CT) based vascular anatomy interpretation.

Method: Patients with left colon and rectal cancer treated surgically with D3 lymph node dissection and selective vascular ligation were included in this study.

Machine Learning-Based Risk Prediction of Critical Care Unit Admission for Advanced Stage High Grade Serous Ovarian Cancer Patients Undergoing Cytoreductive Surgery: The Leeds-Natal Score.

Achieving complete surgical cytoreduction in advanced stage high grade serous ovarian cancer (HGSOC) patients warrants an availability of Critical Care Unit (CCU) beds. Machine Learning (ML) could be helpful in monitoring CCU admissions to improve standards of care. We aimed to improve the accuracy of predicting CCU admission in HGSOC patients by ML algorithms and developed an ML-based predictive score.

Extended Colectomy Followed by Cecorectal Anastomosis as a Surgical Treatment Modality in Synchronous Colorectal Cancer.

Subtotal and extended left colectomies with ileocecal junction preservation represent preferable alternatives in cases of massive involvement of the colon in the pathological process. However, these approaches might be challenging in terms of reconstructive steps. Antiperistaltic cecorectal anastomosis is one of the possible techniques.
