BACKGROUND: Extrathoracic lung sequestration is a rare variant of a developmental malformation that can be diagnosed prenatally and should be included in the differential diagnosis of abdominal tumor-like formations. CASES REPORT: From 1996 to 2020, 70 children with confirmed lung sequestration were treated at the Children's City Hospital No. 1 in St. Petersburg. Of these, 29 had intralobar sequestration, and 41 had extralobar sequestration. Four of these patients were diagnosed with a rare extrathoracic (intraabdominal) form. All four were born full-term without clinical manifestations of the defect. Ultrasound examination of all children revealed a solid formation up to 3 cm in diameter, located in the upper left quadrant of the abdominal cavity or retroperitoneal space in the projection of the left adrenal gland. Due to the location of the formation and the inability to visualize the aberrant arterial vessel during ultrasound examination, the first two patients were differentially diagnosed with an adrenal tumor (neuroblastoma). The cancer markers were negative, and adrenal cortex hormones were normal. The children underwent multispiral computed tomography-angiography to clarify the diagnosis. In both cases, the diagnosis of intraabdominal extrapulmonary sequestration with a feeding arterial vessel extending from the thoracic aorta was confirmed. Two children, previously treated in the last two years, were diagnosed by the ultrasound examination results that enabled the visualization of an aberrant arterial vessel feeding the sequester. Indications for surgical treatment have been set. The parents of one child refused treatment. Three children underwent sequestration removal (two by laparoscopic access, one had a laparotomy). Histologically, extrathoracic sequestration in combination with cystoadenomatosis was confirmed. The postoperative period proceeded without complications. RESULTS: Long-term treatment results were observed in all operated patients for a period of four to 10 years. The assessment was performed based on complaints and ultrasound data. All patients matured and developed according to their ages. CONCLUSIONS: Extrathoracic lung sequestration is a rare type of defect that is subject to surgical treatment. This pathology should be included on the spectrum of differential diagnosis of tumorous formations of the abdominal cavity and retroperitoneal space in newborns. The main methods for postnatal diagnosis of the defect are ultrasound and multispiral computed tomography-angiography.

Aim. To evaluate the results of Doppler ultrasound and multislice computed tomography angiography in patients with gastric cancer and the sensitivity of these diagnostic methods for the detection of the abdomen great vessels lesions.Methods. The study included 32 patients aged 37 to 82 years who had histologically confirmed gastric adenocarcinoma diagnosis. The control group consisted of 30 apparently healthy people of the same age. Transabdominal ultrasonography of the abdominal cavity organs and stomach in gray-scale mode (B-mode before and after the stomach filling with degassed liquid), Doppler ultrasound of the abdomen and the stomach wall vessels, multislice spiral computed tomography angiography were performed in all patients at the preoperative stage. The analysis of the study results and their comparison with intraoperative data were conducted.Results. In patients with gastric cancer a statistically significant increase in peak systolic velocity in the celiac trunk, superior mesenteric artery, left gastric artery and resistive index decrease in these blood vessels (p <0.05) with the presence of atypical vascularization in the affected stomach walls were registered. The data obtained during the multislice spiral computed tomography angiography were analyzed. The sensitivity of Doppler ultrasound in the preoperative detection of abdominal cavity great vessels affection in patients with gastric cancer was 77.8%, multislice spiral computed tomography angiography - 88.9%, the combination of these two methods - 96.3%.Conclusion. The analysis of used diagnostic methods of examination of patients with stomach cancer showed that Doppler ultrasound should be included in the patients examination standard to assess the abdominal cavity great vessels condition, what is important in deciding on the possibility of operative intervention; the sensitivity of the combination of dopplerography and multislice spiral computed tomography angiography in the diagnosis of great vessels affection is 96.3%.

Oesophageal Duplication Cyst

A 7-year-old intact male Rottweiler dog was evaluated for recurrent dysphagia and regurgitation. Physical examination was unremarkable and routine blood works were within normal limits. Computed tomography revealed a defined lesion in the caudal mediastinum arising from the oesophagus. The lesion was excised using intercostal thoracotomy and the histological diagnosis was oesophageal duplication cyst. The dog recovered uneventfully and at a 3-year follow-up no clinical signs were reported. Although extremely rare, oesophageal duplication cysts should be considered in the differential diagnosis in cases of chronic regurgitation and dysphagia associated with evidence of an oesophageal lesion.

Abstract Background Pleuroperitoneal communication (PPC) is an uncommon, but potentially life-threatening complication of peritoneal dialysis (PD). If a fistula does not close with conservative treatment, surgical repair is required. However, approximately half of these patients are forced to shift from PD to hemodialysis. Although it is important to confirm the site of the fistula to achieve a successful surgical treatment, this identification is more difficult in pediatric patients than in adults. Case presentation We report two infantile cases of severe PPC associated with PD. In both cases, the age at onset was less than 2 years, and right-sided pleural effusion with dyspnea was observed. PPC was diagnosed by the change in color of the pleural fluid after the injection of a dye into the peritoneal cavity. Peritoneal scintigraphy and single-photon emission computed tomography and computed tomography (SPECT/CT) were performed, and these were effective in locating the fistula site. Endoscopic surgery (video-assisted thoracic surgery (VATS) and laparoscopic surgery) was performed. Indocyanine green (ICG), which was injected into the abdominal cavity, showed the exact site of the fistula. The fistula was successfully closed by attaching an absorbable sheet to it from the thoracic side and an autograft (the falciform ligament) to it from the abdominal side in one patient. In the other patient, the fistula site was resected and sutured, and reinforced with an absorbable sheet. In both cases, PD was resumed without any complication. Conclusion We successfully treated two infants of PPC by endoscopic surgery. To identify the fistula site, the ICG navigation method was useful. Even in small infants, PPC can be treated successfully by endoscopic surgical repair if the site of the fistula is identified.

Relevance. Pulmonary sequestrations are rare pathology and make from 0.15 to 6.4 % of all congenital abnormality. Thus intra-abdominal localization of this malformation is described only in 2.5 % of all pulmonary sequestrations. Objective. Reflect the difficulty of differential diagnosis of rare lung malformation in newborns. Materials and methods. 2 cases of the extralobar sequestration located under the diaphragm diagnosed for newborns in a children's hospital for the last 20 years are in details described. Results. The diagnosis of an intra-abdominal extralobular pulmonary sequestration was finalized only after surgical treatment, confirmed histologically. Questions of differential diagnostics of rare congenital pulmonary malformations are discussed with tumors of suprarenal localization at newborns, comparison of own results to data of literature. Conclusions. In the differential diagnosis of suprarenal lesions at newborns it is necessary to consider the possibility of intra-abdominal extralobar pulmonary sequestration, especially in the localization of pathological changes at the left side.

Computed tomography (CT) of the abdominal cavity is a promising diagnostic method in cases where conventional radiography does not provide the necessary information, especially when the internal organs of the abdominal cavity and retroperitoneal space are affected. Thanks to the technical improvements made in the latest generations of computed tomographs, the scanning time has been significantly reduced, the image quality has been improved due to the elimination of artifacts by the optimal choice of the level and width of the window, as well as reducing the thickness of the sections and an appropriate approach to the study area. CT allows for targeted biopsy.

Torsion Of The Gallbladder

Abstract Torsion of the gallbladder is a rare entity that is difficult to diagnose preoperatively, the principal differential diagnosis being cholecystitis. The condition occurs most often in the elderly. Although its etiology is unknown, the presence of a redundant mesentery is a prerequisite for torsion. Computed tomography, ultrasound, and magnetic resonance cholangiopancreatography can provide important diagnostic clues. Torsion of the gallbladder occurs when it twists axially, with subsequent occlusion of bile or blood flow. Therefore, prompt surgical treatment is necessary in order to prevent necrosis and perforation. In the present study, we report a case of torsion of the gallbladder diagnosed by magnetic resonance cholangiopancreatography. This condition was successfully treated by laparoscopic cholecystectomy.

Summary. Objective — increasing the efficiency of diagnosis and treatment in patients with destructive forms of pancreatitis. Materials and methods. 89 patients with acute destructive pancreatitis were examined. There were 37 men (41,5 %), 52 women (58,4 %). The average age of patients ranged from 28 to 64 years. In order to objectively assess the severity of the inflammatory process in the pancreas and surrounding tissues, organs of the abdominal cavity, clinical and biochemical studies were used, as well as high-tech methods such as ultrasound examination with dopplerometry, computed tomography. Results. According to ultrasound, the edematous form of acute pancreatitis was diagnosed in 22 (27,4 %) patients during the examination, fatty pancreatic necrosis was diagnosed in 19 (21,3 %) patients. Hemorrhagic pancreatic necrosis was found in 31 (34,8 %) patients, mixed in 17 (19,1 %) patients. The study revealed the main etiological factors of the disease, while in 63 (70,8 %) patients the cause of acute pancreatitis was biliary pathology, alcohol etiology occurred in 17 (19,1 %) patients, and 9 (10,1 %)) - she had a post-traumatic character. Computed tomography was performed in cases of doubt in the data of ultrasound examination, especially in patients with overweight, and for the purpose of differential diagnosis in 23 (25,8 %) patients. Conclusions. Acute destructive forms of pancreatitis have a polymorphic echography picture. Ultrasound diagnostics and computed tomography should be mandatory elements of the diagnostic algorithm for various forms of acute destructive pancreatitis. The diagnostic accuracy of these non-invasive methods in verification of acute destructive pancreatitis and its complications as a whole was 92,8 %. A decrease in the level of postoperative complications and mortality associated with a decrease in the progression of pancreatic necrosis because of suppression of pancreatic secretion.

Aim - to evaluate the effectiveness of minilaparotomic access under intraoperative ultrasound navigation in the surgical treatment of liquid formations in the abdominal cavity and retroperitoneal space in comparison with the puncture-draining interventions under ultrasound guidance. Material and methods. The analysis covered the treatment of 77 patients with interventions for liquid formations of the abdominal cavity and retroperitoneal space using minimally invasive ultrasound-controlled technologies. Among them, 33 patients underwent puncture-draining interventions under ultrasound navigation (I group). Group II consisted of 44 patients with minilaparotomic surgery under intraoperative ultrasound guidance. Results. It is shown that minilaparotomic access under intraoperative ultrasound navigation allows performing one-step sanitation and drainage of abdominal structures of the abdominal cavity and retroperitoneal space, containing in the lumen not only liquid, but also dense necrotic tissues. Conclusion. The process is technically feasible in any surgical hospital, economically relevant, since it does not require the purchase of additional equipment. Application of this method can significantly reduce postoperative mortality.
