“…Currently, the surgical anatomy of the gastrointestinal tract is an advanced area of abdominal surgery, which considers the embryological data on the rotation of the primary gut and fusion fascia [31,32]. Moreover, many studies on laparoscopic oesophageal surgery geometrically based on key anatomical landmarks appeared recently, particularly applying the hypothesis of a "concentric-structured model" [33].…”

“…Although located within one layer, these structures can be derivatives of different embryonic primordia, which signi cantly in uence the likelihood of regional metastases along these structures. In addition, the separation of tissues in avascular layers increases oncological radicality because, without damage to the mesoesophageal layer, it prevents the malignant in ltration of fat planes, thus avoiding the occurrence of implantation metastases [32].…”

Video-assisted thoracoscopic esophagectomy for oesophageal cancer involving the thoracic region has certain advantages. However, thoracoscopic instrument manipulations performed in the narrow confines of the posterior mediastinum carry the risk of intraoperative injury to other vital structures.Purpose of the studyTo improve surgical treatment outcomes of thoracic oesophageal cancer patients using topographic anatomical navigation.Materials and methodsThe study included 23 patients with stages II-III middle and lower thoracic oesophageal cancer (TOC), according to TNM-8. All of them underwent thoracoscopic oesophagectomy in the semi-prone position. While the 1st group of patients (n=15) underwent conventional surgery, in the 2nd group of patients (n= 8), our algorithm of sequential visual navigation based on topographic and anatomical landmarks was employed.ResultsIn the 1st group,4 patients (26.7%) developed intraoperative complications. Out of these four, in 3 patients, injury of the thoracic lymphatic duct complicated with chylothorax development was diagnosed, requiring reoperations; in one patient, the surgery caused damage to the thoracic aorta. Unfortunately, two patients out of these four died.In contrast, there were no intraoperative complications or deaths in the 2nd group. In addition, the algorithm allowed the removal of 18% more lymph nodes, reduction in the incidence of postoperative pneumonia by 25%, the operation time by 25±15 minutes, and the length of stays by 3±2 days, compared with the 1st group of patients. ConclusionTopographic anatomical navigation can reduce the incidence of intra- and postoperative complications, effectively guide lymph node dissection, and shorten hospital stay.

Objective: to evaluate five-year overall and relapse-free survival in patients with complicated rightand left-sided colon cancer that underwent emergency resection.Materials and methods. The study included 501 patients with urgent complications of rightand left-sided colon cancer that underwent emergency resection. The data was obtained from an electronic register containing the information on patients with urgent complications of colorectal cancer treated in general and specialized surgical hospitals in Smolensk between 2001 and 2013 (13 years). We assessed fiveyear overall and relapse-free survival in these patients.Results. A total of 501 resections were performed during the study period. We observed significant differences in resection statuses of patients after emergency resection: the R1 resection status was more frequent in individuals with right-sided colon cancer compared to those with left-sided colon cancer (20.8 % vs. 6.9 %, p = 0.0002). Mean number of lymph nodes examined was 4.6 ± 2.0 in patients with right-sided cancer and 5.3 ± 3.0 in patients with left-sided cancer (p = 0.18). There were no differences in the number of patients receiving adjuvant treatment between the groups (p = 0.11). Patients with left-sided stage II/IIIB/IIIСcomplicated colon cancer demonstrated better overall and relapse-free survival than those with right-sided tumors of the same stages (overall survival: p = 0.007, p = 0.0002, p = 0.0001 for stages II, IIIB, IIIСrespectively; relapse-free survival: p = 0.005, p = 0.0003, p = 0.0002 for stages II, IIIB, IIIСrespectively).Conclusion. The observed differences in the outcomes of treatment for rightand left-sided complicated colon cancer can be explained by the fact that the majority of emergency resections for right-sided tumors were one-stage and were performed in general surgery hospitals. Patients with left-sided cancer underwent tumor removal on the second stage more often than those with right-sided cancer (32 % vs. 13 %). Treatment of patients with complicated colon cancer should be consistent, stepwise, and pathogenetically reasonable.
