Modem therapeutical protocols for treatment of T3 and T 4 malignomas of the larynx are not adjusted, because there are attempts to treat these diseases with non-operative methods (such as chemo- and radiotherapy) in order to preserve the organ. The aim of the study was to establish today's results of the surgical treatment of patients with T3 and T4 laryngeal malignoma. We studied the group of patients with laryngeal carcinoma, who had undergone total laryngectomy, during the period of eight years (1990-1997). The patients' data was submitted from medical documentation, it was filled in specially designed questionnaires and was statistically reviewed. During this eight-year-period. 1054 total laryngectomies were done. The five-years survival rate, established in the group of patients who had undergone total laryngectomiy is 308/794 (39%). In the patient group where total laryngectomy was salvage surgery after radiotherapy, the five-years survival rate is 47/172 (27%). In the patient group where total laryngectomy was salvage surgery after conservative or reconstructive surgery, the five-years survival rate is 28/84 (33%). Despite diagnostical and therapeutical achievements, prognosis for T3 and T4 malygnoma of the larynx was not significantly approved in the last few decades.

AbstractIn the period from 1976 to 1988, 417 patients with supraglottic carcinoma of the larynx were treated by primary surgery.Infiltration of the pre-epiglottic space was found in 11.99 per cent (50/417) of the patients. Carcinomas of the infrahyoid epiglottis spread to this space more frequently—14.24 per cent (44/309), than those of suprahyoid localization—5.55 per cent (6/108). Tumour invasion of the pre-epiglottic space is a relative contraindication for reconstructive surgery. Partial conservation operations were performed on 32 per cent (16/50) of patients with invasion of the pre-epiglottic space. The remaining patients had a total laryngectomy.Infiltration of the paraglottic space intra-operatively was found in 2.4 per cent (10/417) of patients and all of these tumours were from the infrahyoid localization. Spread of tumours to this site is an indication for radical surgery and laryngectomy was performed on 80 per cent (8/10) of patients.

AbstractDuring the period 1976–1988, 988 patients were treated surgically for laryngeal cancer of whom 61 were below the age of 40 years.In 29 patients the tumour was localized in the supraglottis, and in 32 in the glottis. T1 tumour was present in 32 (52.46 per cent), and T2 tumour in six (9.84 percent) patients. Advanced T3 and T4 tumours were present in 13 (21.31 per cent), and (16.39 per cent) patients respectively. The majority had clinically negative findings in the neck (N0). Conservative or reconstructive surgery was applied in 39 (63.93 per cent), and radical in 22 (36.07 per cent) patients. Planned post-operative radiotherapy was carried out in 28 (45. 90 per cent) patients.The five-year survival rate of the studied patients was 83.61 per cent (51/61). The five-year survival rate of the patients with laryngeal carcinomas within the same period was 68.32 per cent (675/988). There was no significant difference in survival rate: X2 = 0.018, DF = 1, p>0.05.

Objective: To investigate which is the best surgical treatment for the gallbladder cancer patient. Summary Background Data: Up to now, the aggressive surgery for advanced gallbladder cancer is controversial. In this study, we analyzed gallbladder cancer patients' data retrospectively and want to find out which is the best surgical treatment for the patient. Methods: From 2009 to 2013, 315 cases of gallbladder carcinoma were identified. Data were analyzed retrospectively. The review included analysis of survival rate, postoperative complications, operative mortality rate, and correlation between local extent of the primary tumor and frequency of nodal metastases. Results: Postoperative complications occurred in 15 (6.2%) patients. 3% of patients who underwent a radical surgery procedure had complications, but in extended radical surgery group, it was 9.8%. Operative mortality rate is 4.94%. No lymph node metastases were found in patients with T1 tumors. Nodal involvement in patients with T3 (55.22%) and T4 (82.50%) tumors was significantly higher than that in patients with T2 (44.12%) tumors. In stage I and II patients, radical resection group had a better survival rate than simple cholecystectomy. In stage III patients, extend radical surgery group and radical surgery group showed a better survival rates than others. In stage IV patients, extend radical surgery group showed 4% survival rate at 2 year, but other group was 0. Conclusions: Simple cholecystectomy may decrease the long survival rates in stage I and II patients. In more advanced stages, extended radical resection should be performed if the R0 resections could be achieved.

The case report of Askin?s tumor in a 16-year-old girl is focused on the still debatable surgical controversy in the treatment of PNET tumor, i.e. whether disarticulation of involved rib at the costovertabral joint should be accepted as the mandatory surgical procedure. It was concluded that the procedure, if feasible, may offer better prognosis of PNET because progression-free survival rate of patients without costovertebral junction involvement reported in multicenter studies was statistically significantly better than in patients in whom PNET has involved the costovertebral junction or bone metastases were present at the diagnosis. The cartilage is a natural barrier for tumor spread and this property should be augmented by radical surgery. Disarticulation of involved rib or ribs and pleurectomy should be routinely performed if the surgery is contemplated with proper timing between the cycles of induction chemotherapy.

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.

Abstract Background Thyroid lobectomy is recommended with total laryngectomy for laryngeal cancer in the National Comprehensive Cancer Network (‘NCCN’) guidelines. However, it is associated with a 32–89 per cent risk of hypothyroidism, with or without adjuvant radiotherapy. Objective The study aimed to determine whether preserving the whole thyroid, compared to a single lobe, does indeed significantly lower the incidence of hypothyroidism in the setting of total laryngectomy. Method A retrospective study was conducted at Groote Schuur Hospital in Cape Town, South Africa. Results Eighty-four patients met the inclusion criteria. The overall incidence of hypothyroidism was 45.2 per cent. The incidence of hypothyroidism was significantly reduced in patients who underwent thyroid-sparing total laryngectomy compared to hemithyroidectomy (p = 0.037). Adjuvant radiotherapy was associated with a higher incidence of hypothyroidism (p = 0.001). Conclusion Thyroid-preserving laryngectomy should be advocated in carefully selected patients with advanced laryngeal carcinoma, as it reduces the incidence of hypothyroidism.
