Additionally, while there were some differences in the level of internal dietary variability among the ayllus, once time was fully considered, none of the ayllus stood out for having a more (or less) clearly internally differentiated cuisine. Finally, sex does not appear to have been a particularly salient driver of observed dietary differences here. While we do not see any de facto evidence for complete dietary differentiation (as there is always overlap in consumption among individuals, ayllus, and time periods, and as isotopic analysis is not capable of pinpointing different foods items or preparations), there are broad aspects of dietary composition changing over time that are potentially linked to status, and foreignness. Ultimately, these stand as the clearest example of what has been termed “gastro-politics,” potentially tied to the emergence of social inequality in the San Pedro oases.The authors characterize a rare variant of Langerhans cell histiocytosis in a child of early age. see more Multiple-system form including liver damage is characterized by a particularly severe course, especially in early childhood. The authors report clinical, morphological and immunohistochemical data of the patient aged 1 year and 11 months. It is shown that timely diagnosis of this disease should be carried out in close cooperation of surgeons and morphologists.Metastases of the right colon cancer to extra-regional lymph nodes are rarely observed. Available literature data cannot be a reliable guide to choose the optimal treatment strategy. Indeed, excision of extra-regional lymph nodes is a rare experience and its results are poorly represented. According to our clinical experience, surgical intervention following comprehensive examination may be radical in patients with right colon cancer if distant metastases are absent. Resection of extra-regional lymph nodes can be safely performed in these cases. We report a patient with the right colon cancer and lesion of extra-regional lymph nodes behind the pancreatic head, paracaval and paraaortic space, hepatoduodenal ligament. Standard laparoscopic right-sided hemicolectomy with D-3 lymph node dissection was accompanied by resection of a conglomerate of nodal metastases behind the pancreatic head and superficial resection of the pancreas. Extra-regional lymph node excision is a reasonable option for colon mucinous adenocarcinoma stage I-III. However, comprehensive preoperative examination is required. Technical difficulty of extra-regional lymph node excision it is not the reason for limitation of surgical intervention. However, safe and total resection requires an adequate surgical approach.Chronic liver disease is a serious worldwide problem because its progression is accompanied by liver fibrosis and cirrhosis at the terminal stages. Primary diagnosis and dynamic assessment of liver fibrosis are essential to determine the prognosis of disease and optimal treatment strategy. Long-term world experience in the use of gadoxetic acid (primovist, eovist) for diagnosis of liver diseases confirms its hepatotropic properties. Thus, magnetic resonance imaging (MRI) in hepatobiliary phase of contrast enhancement is valuable for differential diagnosis of focal liver lesions and assessment of liver structure and fibrotic changes. This review is devoted to the most common methods of contrast-enhanced MRI for assessment of liver function and correlation between severity of diffuse structural liver changes and gadoxetic acid accumulation in liver parenchyma. There is no a single method for MRI-based analysis of liver function that is confirmed by active researches in this direction. It was found that liver biopsy can by unnecessary in some cases if contrast-enhanced MRI with gadoxetic acid is available. The advantage of gadoxetic acid is also elimination properties. Indeed, biliary excretion ensures T1-weighted MR-cholangiography for additional assessment of patency, function and anatomy of the bile ducts. However, there are still several questions in this area that necessitates further research.The problem of chronic postoperative pain has been actualized for the last 20 years all over the world. At least 10-40% of patients suffer from chronic pain after surgery. This review is devoted to the current state of the problem of chronic postoperative pain, risk factors and prediction of chronic pain. The authors emphasize the need for interdisciplinary approach to prevention and treatment of this adverse event.

To evaluate an efficiency and safety of perioperative fast track management in reconstructive esophageal surgery.

Perioperative fast track management protocol in reconstructive esophageal surgery has been applied since 2014 at the Department of Thoracoabdominal Surgery and Oncology of the Petrovsky Russian Scientific Center of Surgery. These patients (2017-2020) were included in the main group (

=75). Patients who underwent traditional perioperative care (2010-2013) were enrolled in the control group (

=63). The primary outcome was postoperative hospital-stay. We also evaluated ICU stay, incidence of complications according to Clavien-Dindo grading system with particular registration of respiratory complications, mortality, enteral and oral feeding onset.

There were no significant between-group differences in sex, age, ASA grade, body mass index. Fast track management reduced hospital-stay from 14 (12; 17) days in the control group to 11 (8; 22) days in the main group (

=0.008). Mean ICU-stay decreased up to 1 (0.8; 2) day in the main group compared to the control group (4.1 (3.5; 5.6) days,

<0.0001). Pneumonia was noted in 5 patients after fast track recovery and 15 patients in the control group (

=0.004). No patients died in the main group, 3 (4.8%) patients – in the control group (

=1).

Modern perioperative fast track management protocol is safe and effective for extensive reconstructive esophageal interventions. This approach reduces hospital-stay and ICU stay, as well as the incidence of respiratory complications.
