Оперативное лечение различных заболеваний кишечника сопровождается осложнениями в виде нарушений микроциркуляции в области анастомоза кишки. Ранее нами показана способность лимфостимуляторов пептидной природы восстанавливать нарушенную микроциркуляцию, что послужило основой для настоящего исследования. Цель работы - оценка влияния стимуляции лимфотока в стенке кишки на процессы восстановления микроциркуляции, структуры и функции тонкой кишки в области оперативного вмешательства. Методика. В экспериментах на наркотизированных крысах (хлоралгидрат в дозе 0,6 г/кг в 0,9% растворе NaCl) моделировали различные поражения тонкой кишки (наложение лигатуры, перевязка 1-3 брыжеечных артерий, перекрут петли кишки вокруг оси брыжейки, сочетание нескольких видов повреждений). Резекция поврежденного участка через 1 сут. с последующим созданием тонкокишечного анастомоза завершалась орошением операционного поля раствором пептида-стимулятора лимфотока (40 мкг/кг массы животного в 1 мл 0,9% раствора NaCl). На 7-е сут. после операции проводили гистологическое исследование фрагмента кишки в области анастомоза. Результаты. На 7-е сут. после резекции у выживших животных (летальность вследствие кишечной непроходимости составляла 30%) имеют место морфологические признаки острых сосудистых нарушений стенки кишки, изменений кровеносных и лимфатических микрососудов, интерстициальный отек всех слоев стенки кишки, дилатация просвета кишки, повреждение всасывающего эпителия ворсин с истончением щеточной каемки клеток, морфологические признаки гиперфункции бокаловидных клеток. Использование лимфостимулятора пептидной природы после операции увеличивало выживаемость животных на 24%. У части животных отмечалось уменьшение расширения просвета кишки, у других практически полная его нормализация. Восстанавливалась форма кишечных ворсин и распределение бокаловидных клеток. Отсутствовали признаки внутриклеточного и межмышечного отека. Отмечено умеренное полнокровие венул. Заключение. Использование лимфостимулятора при хирургическом лечении кишечной непроходимости увеличивает выживаемость животных на 24% по сравнению с контролем, способствует более раннему восстановлению структуры и функции тонкой кишки. Полученные результаты свидетельствуют о перспективности использования стимуляции лимфотока при операциях на кишечнике. Surgical treatment of bowel diseases is associated with complications that cause microcirculatory disturbances in the anastomosis area and may lead to a fatal outcome. This study was based on our previous finding that peptide-type lymphatic stimulators are able to restore impaired microcirculation. The aim of this work was stimulating the lymph flow in the intestinal wall to facilitate recovery of microcirculation, structure and function of the small intestine in the area of surgical intervention. Methods. In experiments on anesthetized rats (0.6 g/kg chloral hydrate in 0.9% NaCl), various small bowel lesions were modeled (bowel ligation, ligation of 1-3 mesenteric arteries, gut torsion, combination of several lesion types). In 24 h, the damaged area was resected, and a small intestine anastomosis was creased. The surgery was completed with irrigation of the operative field with a solution of lymph flow stimulating peptide (40 мg/kg body weight in 1 ml of 0.9% NaCl). A gut fragment from the anastomosis area was examined histologically on day 7 after the surgery. Results. On the 7th day after removing the intestinal obstruction, the surviving animals (lethality 30%) had morphological signs of acute vascular disorders in the intestinal wall; changes in blood and lymphatic microvessels; interstitial edema of all intestinal wall layers; dilatation of the intestinal lumen; damage to the absorptive epithelium of villi with thinning of the brush border, and hyperfunction of mucous (goblet) cells. The use of the peptide after surgery increased the survival rate of animals by 24% and provided a smaller dilatation of the intestinal lumen in some animals. In other animals, the lumen recovered. The shape of intestinal villi and distribution of goblet cells were restored. Signs of intracellular and intermuscular edema were absent. Moderate venular congestion was noticed. Conclusion. Using the lymphatic stimulator in surgical treatment of intestinal obstruction increases the survival rate of animals by 24% compared to the control, facilitates earlier restoration of the small intestine structure and function. The obtained results indicated the effectiveness of lymphatic stimulation in intestinal surgery.

Duodenal Resection

Although malignancies involving the small bowel are rare, one-third of these are located in the duodenum. The majority of duodenal tumors are adenocarcinoma but also may include gastrointestinal stromal tumors (GIST), carcinoid or neuroendocrine tumors, sarcomas, and lymphoma. These commonly present with nonspecific symptoms, but obstructive patterns predominate when symptoms are present. Preoperative diagnosis is made via endoscopy and/or cross-sectional imaging. This section focuses on treatment and surgical management for adenocarcinoma, carcinoid tumors, and GISTs of the duodenum. Surgical resection is the primary treatment of for all three of these, but all have significant nuances in surgical planning and decision-making as well as variability in the role of adjunctive treatment in their management. Functional carcinoid tumors can have hormone-driven symptoms and are associated with an increase in risk of carcinoid crisis, which may be prophylactically treated with intravenous octreotide. Resection of these tumors relies heavily on tumor relationship to the ampulla. Key anatomic distinctions and clinical tips to identify the ampulla to ensure an appropriate duodenal resection are discussed in this review. This review contains 12 figures, 5 tables, and 54 references. Key Words: carcinoid, duodenal carcinoma, duodenal adenocarcinoma, duodenal resection, duodenal tumors, neuroendocrine tumor, gastrointestinal stromal tumor, small bowel tumors

CONTEXT: Colonic carcinoids, excluding those arising in the appendix, have proved to be extremely rare. Due to their rarity, the characteristics and behavior of this unusual malignancy remain unclear. OBJECTIVE: To review the clinicopathologic features of patients operated on carcinoid tumors of the colon. METHODS: Twenty-three patients (12 males and 11 females) were operated on colonic carcinoids. The mean age of the patients was 63.0 ± 12.9 years (42 to 85 years). The clinical and histopathological data of patients who were pathologically diagnosed as having carcinoid tumors and submitted to surgical treatment over a 30-year period (1977-2007) were gathered. Actuarial patient survival was estimated using the Kaplan-Meier method, with carcinoid-specific death as the outcome. RESULTS: The mean time elapsed between onset of symptoms and surgical treatment was 8.3 months (1.5 to 20 months). The most frequent symptoms or signs encountered were abdominal pain followed by anorexia or weight loss, diarrhea, abdominal tenderness, palpable abdominal mass, and rectal bleeding. No carcinoid syndrome was noted. The lesion was located in the cecum in 16 (69.6%) patients, in the sigmoid in 3 patients (13.0%), in the ascending colon in 3 patients (13.0%), and in the transverse colon in one patient (4.3%). Twenty-one (91.3%) patients were operated on curative intent. Spreading of the disease to the liver and peritoneum was found in two (8.7%) patients who submitted to intestinal bypass. The mean size of the largest mass was 3.7 ± 1.2 cm (1.5 to 6.2 cm). There were multiple (two or more) lesions in three cases (13.0%). In the resected cases, the lymph nodes were compromised in 10 patients (47.6%) and disease-free in 11 (52.4%). Venous invasion and neural infiltration were both present in five (23.8%) patients. The tumors had penetrated the muscularis propria in all resected cases. Four (17.4%) patients had a second non-carcinoid primary tumor. Three (13.0%) patients died due to postoperative complications and five (21.7%) patients died from metachronous metastases or local recurrence. Fifteen patients (65.2%) remain alive without evidence of active disease. The mean follow-up period was 12 years (1.2 to 18 years), whereas the mean global survival was 50.7 ± 34.2 months and the crude survival rate at 5 years was 62.7%. CONCLUSIONS: Carcinoid tumors of the colon are frequently right-sided and may be clinically occult until an advanced stage is reached. Based on the relatively poor survival rates reported, it is recommended that, in addition to standard surgical resection, vigorous surveillance for metastatic disease must be performed, particularly during the first 2 years after surgery. In addition, these patients require evaluation of the entire gastrointestinal tract for evidence of coexisting malignancy, along with an extended period of follow-up, because tumor recurrences after 5 years are not uncommon.

INTRODUCTION: Hilar/mediastinal lymph node sampling with lobectomy are the most common surgical methods used for the surgical treatment of carcinoid tumors. Bronchoplastic approaches together with lobectomy enable sparing of normal lung tissue and provide an alternative surgical approach to avoid pneumonectomy by enabling sleeve resection for centrally located tumors. The aim of this study was to present our parenchyma-sparing open surgical treatment experiences with the carcinoid tumor cases operated in our clinic in light of the new developments in the literature METHODS: The 11 tumor cases that had been diagnosed with carcinoid tumor and undergone surgical resection at our clinic between 2006 and 2012 were retrospectively revealed for tumor epidemiology, diagnostic methods, tumor localization, surgical treatment method, type and stage and postoperative complications. RESULTS: There were 7 males and 4 females with a mean age of 54.81±13.75 years (31-72 years). Cough was the most common presentation symptom with 8 cases (72.7%). A bronchoscopic biopsy was used for the definite diagnosis in 8 cases (72.7%). There were 11 (84.6%) typical and 2 (15.4%) atypical carcinoid tumors in the 11 cases. The most common surgical methods were lobectomy in 7 cases (53.8%) (3 sleeve, 1 bronchoplastic) and wedge resection in 4 cases. We found bilateral synchronous and 3 years later metachronous carcinoid tumor in a single case. The postoperative pathology diagnosis was T2N0M0 in 6 cases (54.5%) and T1N0M0 in 3 cases (27.2%). There was 1 atelectasis and 1 prolonged air leak in the postoperative stage. DISCUSSION AND CONCLUSION: Although we still use thoracotomy and lobectomy for the surgical treatment of carcinoid tumors in our clinic, we currently prefer minimal invasive surgery with the VATS and robotic surgery techniques that are gradually becoming more popular.

Objective. To estimate the efficacy of early enteral nutrition (EEN) in patients with an acute complicated pancreatitis, after determining of its content  and improving the realization methods. Маterials and methods. There were studied the results of EEN in 82 patients, suffering an acute complicated pancreatitis. Two groups of patients were delineated - the main (n=58), in which EEN was included into the complex of treatment in preoperative and postoperative periods, and a comparative one (n=24). For conduction of EEN the probe was put during fibrogastroscopy into jejunum (in 25 patients), while suboperative nasogastrointestinal intubation was performed (in 12), and a jejunostomy in accordance to Witzel procedure was formatted (in 21), what have appeared the most effective procedure and served for realization of the Fast track surgery principles. Results. Nutritious food blends were applied in combination with probiotics and the metabolism correctors. Application of EEN in the patients іn an acute complicated pancreatitis have promoted more rapid restoration of a motor-evacuation function of a small bowel, normalization of levels of the blood leukocytes and proteins, weakening of microstructural changes in mucosa and «clearance» of purulent-necrotic focus. Conclusion. EEN in the patients, suffering an acute complicated pancreatitis constitutes an effective component of surgical treatment in preoperative and postoperative periods.

Surgical Interventions

Despite the ongoing preventive measures aimed at reducing the formation of adhesions in the abdominal cavity with an increase in the number of surgical interventions on the abdominal organs, the number of patients admitted to surgical hospitals with adhesions of the small intestine is also increasing. It should be noted that annually about 12% of previously operated patients undergo treatment in surgical departments while the exceptional fact is that 5070% are patients with acute adhesive ileus of the small intestine and the mortality rate in this group ranges from 13 to 55%. In recent years the literature has been actively discussing the advantages of minimally invasive technologies in the treatment of adhesive small bowel obstruction since the use of traditional methods often leads to the development of complications with repeated (in 60% of cases) surgical interventions. The purpose of this study was the development and implementation of an improved therapeutic and diagnostic algorithm in patients with adhesive small bowel obstruction which made it possible to improve the results of treatment. A comparative analysis of 338 patients with adhesive small bowel obstruction who were treated in the surgical departments of the St. Elizabeth Hospital in St. Petersburg in the period from 2016-2019 was carried out. All the patients were divided into 2 groups: the main (I) group (2018-2019), which consisted of 198 patients who received the improved diagnostic and treatment algorithm as well as the comparison group (II) (2016-2017) which included 140 cases these are patients examined according to the standard protocol and operated on in the traditional way. Moreover, in 98 cases, it was possible to resolve acute adhesive small intestinal obstruction in a conservative way, and 240 patients underwent surgical treatment. The developed diagnostic algorithm is based on the consistent application of the most informative diagnostic methods. At the same time the indications and the sequence of their application were established which ultimately made it possible to shorten the preoperative time interval as well as to determine the optimal treatment strategy with the choice of the type of surgical treatment (laparotomy or laparoscopy). The proposed treatment and diagnostic algorithm allowed to reduce the complication rate from 46.5% (53) to 22.2% (28) (р 0,001), and the mortality rate from 14.9% (17) to 3.9% (5) (p 0,01).
