[Laparoscopic partial resection of spleen in a 15-year-old girl]. / Laparoskopicheskaya partsial'naya rezektsiya selezenki u devochki 15 let.

Non-parasitic splenic cysts account for 0.5-10% of diseases of this organ. Incidence of splenic cysts has increased in recent years that may be associated with widespread use of abdominal imaging. Symptoms are absent in most cases. Splenic cysts > 5 cm are prone to complications such as bleeding, rupture or infection. These patients require surgical treatment. The authors present multilocular splenic cyst in a 15-year-old patient. The girl was followed-up for 2 previous years due to asymptomatic small cyst. However, cyst enlargement required surgical treatment. Examination revealed multilocular cyst 7×10 cm in the upper pole of the spleen. Enzyme immunoassay did not reveal antibodies to echinococcus. Laparoscopic partial resection of spleen was performed. This case is an example of modern surgical approach for nonparasitic splenic cysts characterized by minimally invasive organ-sparing technologies.

['Conservative' organ-sparing approach for ovarian torsion in children]. / Organosokhraniaiushchee 'konservativnoe' lechenie perekruta pridatkov matki u detei.

AIM: To improve the outcomes in children with ovarian torsion. MATERIAL AND METHODS: Three clinical observations of patients with ovarian torsion are presented. Duration of the disease was 3-4 days. All children underwent organ-sparing surgery including untwisting followed by ovariopexy. RESULTS: All children were examined in early and late postoperative period (up to 5 years) after organ-sparing procedures. Ultrasonic picture of the ovaries including structure and dimensions corresponded to age, the follicles were determined. CONCLUSION: 'Conservative' approach allows to preserve anatomical structure and potential for reproductive function.

[Complications and long-term results of delayed esophagoezophagostomy for esophageal atresia]. / Oslozhneniia i otdalennye rezul'taty otsrochennogo ézofago-ézofagoanastomoza pri atrezii pishchevoda u detei.

AIM: To evaluate complications and long-term results of delayed esophagoesophagostomy in children with esophageal atresia (EA). MATERIAL AND METHODS: 165 EA children were operated at the Filatov Municipal Children's Hospital #13 for the period 2006-2016. Primary esophageal anastomosis was performed in 136 (82.4%) children with tracheoesophageal fistula. In 5 (3%) neonates with non-fistulous EA esophago- and gastrostomy were made for further coloesophagoplasty. Other 24 (14.5%) children underwent gastrostomy for delayed esophagoesophagostomy. 6 (25%) of them died within 12 days after admission. 18 survivors with gastrostomy subsequently underwent delayed esophagoesophagostomy. RESULTS: Postoperative complications occurred in 16 (88.9%) children. Esophageal anastomosis failure occurred in 4 (22.2%) patients, stenosis of anastomosis in 11 (61.1%) children, gastroesophageal reflux in 14 (77.8%) children. Early postoperative mortality was 16.7% (3 children). In remote period 92.3% of children were not adapted to normal diet and only in 7.7% of patients eating behavior corresponds to the age. 11 children underwent prolonged esophageal bougienage. 9 children underwent re-operation after delayed anastomosis. Esophageal extirpation was made in 4 children. CONCLUSION: Esophago- and gastrostomy provides 100% survival if primary esophageal anastomosis is impossible. Herewith, in children without esophagostomy mortality rate was 25%. We still can not confirm that delayed esophageal anastomosis is a good alternative for children with esophageal atresia. In view of our results the number of candidates for delayed esophageal anastomosis should be reduced.

[Differentiated approach to the treatment of large hernial defects of the anterior abdominal wall in children (clinical observations)]. / Lechenie obshirnykh gryzhevykh defektov perednei briushnoi stenki u detei.

AIM: To present an experience of treatment of children with large hernial defects of the anterior abdominal wall. MATERIAL AND METHODS: This article describes management of 43 children with large (n=31) and giant (n=12) ventral hernia who were at N.F. Filatov Children´s City Hospital #13 for the period 2005-2015. All patients underwent surgical correction using local tissues in 'edge to edge' fashion (n=23), aponeurosis dublication of 'coat floors' type (n=14) and biological implant 'Permacol' (n=6). Etiological causes of ventral hernias in children were comprehensively analyzed. Optimal time for surgical treatment and features of viscero-abdominal disproportion were discussed. CONCLUSION: Early restoration of anatomical and functional structures of the anterior abdominal wall is necessary for good cosmetic result and prevention of recurrent ventral hernia. We presented three clinical examples of commonly used surgical procedures in children including anterior abdominal wall repair using biological material 'Permacol'.

[Video-assisted surgery of Hirschsprung's disease in children].

Results of the laparoscopic treatment of 36 patients with Hirschsprung's disease were analyzed. The majority of patients were the newborns or before 12 months old. The use of laparoscopy permitted a full-fledged topical diagnostics, aganglionosis zone identification, gut mobilization and voiding. Laparoscopic method also allowed to decrease the ICU stay in 3,1 times and start breastfeeding earlier, lessen the pelvic floor intraoperative traumatization and decrease the level of commissural and inflammatory complications. Good and excellent functional results were achieved in 93,7% of children, stenosis of the anastomotic area was registered postoperatively in 2 patients.

[Laparoscopic surgery and postoperative adhesions in children].

Data of 568 patients, aged from 3 weeks to 14 years, with acute adhesive bowel obstruction, treated during 1981--2007 yy. are analyzed. Most often previous laparotomy was performed on account of appendicitis, predominately complicated with peritonitis--in 52,2% of patients. Obstruction, caused by intestinal invagination was observed in 19,4%, malformation--9,3%, tumor--2,3%, other--1,7%. The treatment results of appendicular peritonitis and intestinal invagination are studied. Two comparative groups of patients with appendicular peritonitis, 100 children each, were treated laparoscopically and traditionally. The laparoscopic method allows to stop pain and endotoxicosis earlier, faster gastrointestinal function recovery, decrease of complication in the laparoscopical group rates and hospital-stay period on 30,8%. 100 children with intestinal invagination were operated laparoscopically and 50 patients were experienced a traditional <> operation. There were no complications, but 2 cases of postoperative adhesive obstruction in the <> group. The average hospital stay was 2,5 times shortened in the laparoscopical group.

[Laparoscopic surgery in children--current possibilities and perspectives]. / Laparoskopicheskaia khirurgiia u detei--sovremennye vozmozhnosti i perspektivy.

Experience in use of different laparoscopic methods in 6046 children who needed urgent and elective surgeries are analyzed. Urgent surgeries were performed in 3292 children for acute appendicitis and it complications, acute adhesive intestinal obstruction, invagination, trauma of abdominal organs, pathological changes of Meckel diverticulum, urgent inflammatory and non-inflammatory gynecological diseases. In this group endosurgery was successful in 3120 (94.8%) patients, conversion to open surgery was necessary in 5.2% cases (172 patients). Laparoscopic cholecystectomy, splenectomy, nephrectomy, surgeries for cysts of parenchymatous organs, benign cysts and tumors of abdominal cavity and retroperitoneal space, varicocele, syndrome of unpalpable testes and abdominal cryptorchism were performed as elective surgeries in 2754 patients. Endosurgical methods to minimized number of complications (1.1% or 29 patients in the whole group), conversion to open surgery was necessary in 10 (0.4%) cases. Laparoscopic methods in many cases are the "gold standard" in elective and urgent surgery in children.

[Laparoscopic splenectomy in congenital hemolytic anemia in children]. / Laparoskopicheskaia splenéktomiia pri vrozhdennoi gemoliticheskoi anemii u detei.

Experience of 48 laparoscopic splenectomies in children aged from 3 to 14 years with congenital hemolytic anemia is analyzed. The main stages of laparoscopic splenectomy were the following: isolation of the inferior pole of the spleen, transection of the gastro-splenic ligament, transection of the splenic vascular trunk (with endostapler or intracorporeal ligature), dissection of the splenic ligaments, removal of the organ (with endoscopic sac or morcellator). One-stage cholecystectomy for cholelithiasis was performed in 11 patients. Time of surgery was 110-115 minutes, on the average. One-stage cholecystectomy prolonged surgery by 30-40 minutes. There were no intraoperative and postoperative complications. Conversion to open surgery was necessary in 2 cases because of endostapler failure. Patients were discharged on the 5-8th day after surgery. Physical activity restored completely 10-14 days after surgery. There were no lethal outcomes. Excellent cosmetic results were achieved in all the patients. Laparoscopic splenectomy in congenital hemolytic anemia is safe, sparing and effective endoscopic surgery in childhood.
