RESUMO

OBJECTIVE: To analyze the efficacy of intraductal radiofrequency ablation (RFA) for neoplasms of the major duodenal papilla with intraductal spread. MATERIAL AND METHODS: Eleven patients with adenomas of the major duodenal papilla and intraductal spread underwent intraductal RFA between 2022 and 2023. Spread to the common bile duct ranged from 10 to 30 mm, to the main pancreatic duct - from 5 to 11 mm. RESULTS: Technical success was achieved in all cases. Complications after intraductal RFA occurred in 4 cases (post-manipulation pancreatitis - 2 cases, repeated intraductal RFA for residual adenomatous growths - 2 cases). Technical success of stenting of the main pancreatic and common bile ducts was achieved in all cases. CONCLUSION: Intraductal radiofrequency ablation for neoplasms of the major duodenal papilla with intraductal spread ensured complete destruction of intraductal tumor with adequate clinical effect and no need for highly traumatic surgery.

RESUMO

High quality bowel preparation is a necessary part of preoperative preparation for colorectal surgery and one of the keys to the success of surgery, which directly affects the quality of intraoperative procedures and postoperative recovery of patients. Conventional intestinal preparation mainly includes three aspects: preoperative dietary control, intestinal cleansing and prophylactic use of antibiotics. With the development of evidence-based medicine, the concepts and methods of bowel preparation have also changed. Long fasting is no longer advocated before surgery, and the traditional mechanical bowel preparation are also challenged. This article summarizes the application and research progress of different intestinal preparation methods before colorectal surgery, aiming to provide reference for clinical work of colorectal surgeons.

RESUMO

All adenomas of the major duodenal papilla (MDP) require resection regardless of morphological structure due to high risk of malignancy. Currently, intraluminal endoscopic interventions are preferable for these adenomas. MDP neoplasms with intraductal spread (type III and IV) are of particular difficulty for endoscopic techniques. Intraductal radiofrequency ablation provides new opportunities for minimally invasive treatment of patients with MDP adenomas and intraductal component. A 72-year-old patient after previous endoscopic papillectomy for MDP adenoma admitted to the Vishnevsky National Research Medical Center of Surgery due to residual adenomatous growths within the papillectomy zone extending to the common bile duct throughout 13 mm. The patient underwent intraductal RFA under endosonography and cholangioscopy. Despite difficult localization of residual growths extending to the common bile duct, endosonography-guided intraductal RFA provided total destruction of residual tumor that was confirmed by cholangioscopy. Length of treatment was 4 months, relapse-free period - 10 months. Minimally invasive endoscopic technology for residual MDP adenoma provided good clinical results.

RESUMO

Objective: To report the long-term outcomes of Chinese rectal cancer patients after adopting a Watch and Wait (W&W) strategy following neoadjuvant therapy (NAT). Methods: This multicenter, cross-sectional study was based on real-world data. The study cohort comprised rectal cancer patients who had achieved complete or near complete clinical responses (cCRs, near-cCRs) after NAT and were thereafter managed by a W&W approach, as well as a few patients who had achieved good responses after NAT and had then undergone local excision for confirmation of pathological complete response. All participants had been followed up for ≥2 years. Patients with distant metastases at baseline or who opted for observation while living with the tumor were excluded. Data of eligible patients were retrospectively collected from the Chinese Wait-and-Watch Data Collaboration Group database. These included baseline characteristics, type of NAT, pre-treatment imaging results, evaluation of post-NAT efficacy, salvage measures, and treatment outcomes. We herein report the long-term outcomes of Chinese rectal cancer patients after NAT and W&W and the differences between the cCR and near-cCR groups. Results: Clinical data of 318 rectal cancer patients who had undergone W&W for over 2 years and been followed up were collected from eight medical centers (Peking University Cancer Hospital, Fudan University Shanghai Cancer Center, Sun Yat-sen University Cancer Center, Shanghai Changhai Hospital, Peking Union Medical College Hospital, Liaoning Cancer Hospital, the First Hospital of Jilin University, and Yunnan Cancer Hospital.) The participants comprised 221 men (69.4%) and 107 women (30.6%) of median age 60 (26-86) years. The median distance between tumor and anal verge was 3.4 (0-10.4) cm. Of these patients, 291 and 27 had achieved cCR or near-cCR, respectively, after NAT. The median duration of follow-up was 48.4 (10.2-110.3) months. The 5-year cumulative overall survival rate was 92.4% (95%CI: 86.8%-95.7%), 5-year cumulative disease-specific survival (CSS) rate 96.6% (95%CI: 92.2%-98.5%), 5-year cumulative organ-preserving disease-free survival rate 86.6% (95%CI: 81.0%-90.7%), and 5-year organ preservation rate 85.3% (95%CI: 80.3%-89.1%). The overall 5-year local recurrence and distant metastasis rates were 18.5% (95%CI: 14.9%-20.8%) and 8.2% (95%CI: 5.4%-12.5%), respectively. Most local recurrences (82.1%, 46/56) occurred within 2 years, and 91.0% (51/56) occurred within 3 years, the median time to recurrence being 11.7 (2.5-66.6) months. Most (91.1%, 51/56) local recurrences occurred within the intestinal lumen. Distant metastases developed in 23 patients; 60.9% (14/23) occurred within 2 years and 73.9% (17/23) within 3 years, the median time to distant metastasis being 21.9 (2.6-90.3) months. Common sites included lung (15/23, 65.2%), liver (6/23, 26.1%), and bone (7/23, 30.4%) The metastases involved single organs in 17 patients and multiple organs in six. There were no significant differences in overall, cumulative disease-specific, or organ-preserving disease-free survival or rate of metastases between the two groups (all P>0.05). The 5-year local recurrence rate was higher in the near-cCR than in the cCR group (41.6% vs. 16.4%, P<0.01), with a lower organ preservation rate (69.2% vs. 88.0%, P<0.001). The success rates of salvage after local recurrence and distant metastasis were 82.1% (46/56) and 13.0% (3/23), respectively. Conclusion: Rectal cancer patients who achieve cCR or near-cCR after NAT and undergo W&W have favorable oncological outcomes and a high rate of organ preservation. Local recurrence and distant metastasis during W&W follow certain patterns, with a relatively high salvage rate for local recurrence. Our findings highlight the importance of close follow-up and timely intervention during the W&W process.

RESUMO

We studied the expression of insulin-like growth factor 1 (IGF-1), androgen receptor (AR) and luteinizing hormone receptor (LHR) in the ovaries under the conditions of the modeling and subsequent treatment of functional ovarian cysts with gonadotropin-releasing hormone antagonist (ant-GnRH). The intensity of IGF-1, LHR, and AR expression in the generative elements of rat ovaries changed under conditions of functional ovarian cysts simulation, as well as during treatment with ant-GnRH. In both experimental groups, the expression levels of the studied markers in preantral follicles and epithelial lining of cysts were found to be related to the number of growing follicles and cysts. A divergence of LHR and AR expression indices and a more pronounced decrease in the number of cystic cavities were observed in the group receiving ant-GnRH. These changes demonstrate a positive effect of ant-GnRH on intra-ovarian regulatory factors and a therapeutic effect in functional ovarian cysts.

RESUMO

The morphofunctional features of the ovaries were evaluated in rats with functional ovarian cysts model treated with gonadotropin-releasing hormone antagonist. Administration of the antagonist significantly (p=0.009) reduced the number of cysts and the growth of follicles in the ovaries. The obtained results attest to a possibility of successful treatment of functional ovarian cysts with gonadotropin-releasing hormone antagonist.

RESUMO

Objective: To analyze the treatment outcomes and prognoses of children with head and neck non-parameningeal rhabdomyosarcoma (HNnPM RMS). Methods: A retrospective analysis was performed on the clinical data of children with HNnPM RMS admitted to Beijing Children's Hospital from September 2012 to September 2022. The clinical features, comprehensive treatment modes and prognoses of the patients were analyzed. The overall survival rate (OS) and event free survival rate (EFS) were calculated using the Kaplan-Meier method, and univariate analysis was performed using the Log-rank test. Results: A total of 70 children were included in this study, 38 males and 32 females, with a median age of 47 months (2-210 months). Pathological subtypes including the embryonal in 27 cases, the alveolar in 36 cases and the spindle cell and sclerosing in 7 cases. Thirty children (83.3%) with alveolar type were positive for FOXO1 gene fusion. All 70 children underwent chemotherapy, including 38 with neoadjuvant chemotherapy and 32 with adjuvant chemotherapy. Sixty of 70 children underwent surgery, of whom, 10 underwent two or more surgeries. There were 63 children underwent radiotherapy, including 54 with intensity-modulated radiation therapy, 4 with particle implantation and 5 with proton therapy. The median follow-up was 45 (5-113) months, the 5-year OS was 73.2%, and the 5-year EFS was 57.7%. Univariate analysis showed lymph node metastasis (χ2=5.022, P=0.025), distant metastasis (χ2=8.258, P=0.004), and high Intergroup Rhabdomyosarcoma Study (IRS) group (χ2=9.859, P=0.029) as risk factors for poor prognosis. Before June 2016, the 5-year OS based on BCH-RMS-2006 scheme was 63.6%, and after 2016, the 5-year OS based on CCCG-RMS-2016 scheme was 79.6%. Conclusion: Multidisciplinary combined standardized treatment can offer good treatment outcome and prognosis for children with HNnPM RMS. Local control is a key to the efficacy of comprehensive treatment.

RESUMO

OBJECTIVE: This review examined the literature for evidence on the prognostic ability of systemic immune-inflammation index (SII) and pan-immune inflammation value (PIV) for predicting overall survival (OS) and disease-free survival (DFS) in breast cancer patients. MATERIALS AND METHODS: PubMed, Embase, Scopus, and Web of Science were searched with Google Scholar for gray literature. All types of studies reporting the association between SII or PIV and OS or DFS of breast cancer were eligible. RESULTS: 13 studies on SII and 4 studies on PIV were included. Meta-analysis showed that a high SII was a significant predictor of OS (HR: 1.97 95% CI: 1.54, 2.52 I2=76%) and DFS (HR: 2.07 95% CI: 1.50, 2.86 I2=79%) in breast cancer patients. These results did not change on sensitivity analysis and were more or less stable on multiple subgroup analyses. Pooled analysis showed that high PIV was also a significant predictor of poor OS (HR: 2.63 95% CI: 1.46, 4.74 I2=71%) and DFS (HR: 1.64 95% CI: 1.23, 2.17 I2=0%) in breast cancer patients. CONCLUSIONS: High SII and PIV can predict poor OS and DFS in breast cancer patients. High heterogeneity and the observational nature of data are important limitations of the review. Further studies are needed specifically on PIV to increase the strength of the evidence.

RESUMO

The aim of this study was to propose a treatment strategy for intraglandular submandibular calculi based on calculus site. Seventy-three consecutive patients with impalpable intraglandular submandibular calculi were enrolled retrospectively. The calculi were classified as either post-hilar type, central type, or superficial type. Treatment approaches included transoral duct slitting (TDS), interventional basket retrieval (IBR), intraductal laser lithotripsy (ILL), and transcervical lithotomy (TCL). Complete calculus removal with gland preservation was achieved in 64 patients (87.7%). The success rate for post-hilar, central, and superficial calculi was 86.4% (51/59), 90.9% (10/11), and 100% (3/3), respectively. The treatment approach applied in patients with treatment success was TDS in 32 cases, IBR in 20, ILL in nine, and TCL in three. During follow-up (median 17.3 months), one patient experienced gland atrophy and three had ductal stenosis; the remaining 60 patients (93.8%, 60/64) had good clinical outcomes. In the eight failure cases operated by TDS, the deeply situated calculi could not be detached despite the parenchymal incision in five cases, while the procedure was ceased due to the patient's inability to cooperate in the other three cases. In the remaining failure case, the submandibular gland was sacrificed after calculus extraction via TCL. Application of the proposed treatment algorithm might help preserve gland function in patients with intraglandular submandibular calculi.

RESUMO

BACKGROUND: Treatment of acromegaly is still an unresolved problem. Overall postoperative remission rate ranges from 34 to 85%. These values are better for microadenomas (75-90%) and worse for macroadenomas (45-70%). Identification of predictors of acromegaly remission after surgical treatment is an urgent objective to improve the quality of medical care for these patients. OBJECTIVE: To analyze postoperative freedom from acromegaly and predictors of remission. MATERIAL AND METHODS: A retrospective single-center study included 227 patients with acromegaly who underwent resection of pituitary adenoma between August 2018 and August 2021. RESULTS: Remission (normalization of serum IGF-1) was achieved in 65 (55%) patients. Growth hormone and IGF-1 index decreased after surgery in all patients. Mean preoperative serum growth hormone was 12.45 [6.88, 29.85] ng/ml, early postoperative concentration - 1.54 [0.80, 3.38] ng/ml, in delayed period - 1.15 [0.57, 3.80] ng/ml. Mean IGF-1 index was 2.18 [1.69, 2.71], 1.47 [0.99, 1.90] and 0.99 [0.74, 1.43], respectively. CONCLUSION: Significant predictors of acromegaly remission after neurosurgical treatment were age, preoperative level of growth hormone, tumor size and location, growth hormone and IGF-1 index in early postoperative period and residual tumor after surgery. Multivariate analysis revealed a significant association of acromegaly remission with small tumor size, low postoperative level of growth hormone and no residual tumor within 3-6 month after surgery.

RESUMO

BACKGROUND: Chordoid glioma is a rare slow-growing tumor of the central nervous system. Available world experience includes no more than 200 cases (lesion of the third ventricle in absolute majority of cases). Recognition and treatment of chordoid glioma are currently difficult problems due to small incidence of this disease. OBJECTIVE: To describe clinical manifestations and surgical treatment of chordoid glioma of the third ventricle considering literature data and own experience. MATERIAL AND METHODS: There were 12 patients (6 men and 6 women) with chordoid glioma between 2004 and 2023 (10 patients with lesion of the third ventricle, 1 - lateral ventricle, 1 - pineal region). Only patients with tumors of the third ventricle were analyzed. RESULTS: Total and subtotal resection was performed in 1 and 3 cases, respectively. Five patients underwent partial resection, 1 patient underwent biopsy. The follow-up data were available in 7 out of 10 patients (mean 25 months). Radiotherapy was performed in 4 patients (continued tumor growth in 2 cases). One patient died. CONCLUSION: Chordoid glioma is a benign tumor predominantly localized in the third ventricle. Preoperative MRI and CT in some cases make it possible to suspect chordoid glioma and differentiate this tumor from craniopharyngioma, meningioma and pituitary adenoma by such signs as isointense signal in T1WI, hyper- or isointense signal in T2WI, homogeneous contrast enhancement and edema of basal ganglia in T2 FLAIR images. The only effective treatment for chordoid glioma is surgery. Total resection is often impossible or extremely dangerous due to location of tumor, large size and invasion of the third ventricle. Postoperative mental disorders and diabetes insipidus, including severe hypernatremia, are common that requires mandatory monitoring of water and electrolyte balance.

RESUMO

Fibrovascular polyp is a rare non-epithelial esophageal tumor arising from submucosal layer and consisting of connective and adipose tissue, as well large number of vessels. Large tumors can cause dysphagia, vomiting, chest pain, shortness of breath and/or asthma, while giant neoplasms are potentially life threatening. Despite active introduction of minimally invasive treatment of patients with non-epithelial gastrointestinal tumors, there are still difficulties in surgical treatment of fibrovascular polyps. The patient with a giant fibrovascular esophageal polyp presented with cough, discomfort in the throat, impaired swallowing and episode of tumor migration into oropharynx. Examination confirmed giant highly vascularized esophageal fibrovascular polyp. A novel hybrid surgical technique (endoscopic submucosal dissection with laparoscopic removal of tumor) was applied. Eight-month follow-up revealed no complications. Favorable clinical result was achieved. A hybrid laparo-endoscopic approach in the treatment of patients with large fibrovascular polyps minimizes perioperative risks and improves postoperative outcomes.

RESUMO

Reset osmostat syndrome (ROS) is characterized by a change of normal plasma osmolality threshold (decrease or increase), which leads to chronic dysnatremia (hypo- or hypernatremia). We have described a clinical case of ROS and chronic hyponatremia in a patient with chordoid glioma of the III ventricle. It is known that the patient had previously been diagnosed with hyponatremia (131-134 mmol/l). She has not hypothyroidism and hypocorticism. There is normal filtration function of the kidneys was (CKD-EPI 91.7 ml/mi/1,73m2). Urine osmolality and sodium level were studied to exclude of concentration kidney function disorder. During first three days after removal of the tumor of the third ventricle (chordoid glioma, WHO Grade II), the sodium level decreased to 119 mmol/l. Repeated infusions of 200-300 ml hypertonic 3% sodium chloride solution, gluco- and mineralocorticoid therapy was ineffective, increasing plasma sodium levels by 2-3 mmol/l with the return to the initial level during 6-8 hours. Hypopituitary disorders did not develop after surgery. With further observation, the sodium level remained within 126-129 mmol/l for 6 months after surgery. The water load test make exclude the classic syndrome of inappropriate secretion of antidiuretic hormone, and confirmed the diagnosis of RSO. Because of absence of clinical symptoms associated with hyponatremia, no medical correction was required, patient was recommended to clinical follow-up.

RESUMO

Castleman disease (CD) is a benign lymphoproliferative disease. Small prevalence and diverse clinical course of disease makes it difficult to standardize diagnostics and treatment. Currently, the number of CD patients has increased with improvement in the quality of examination. Therefore, differential diagnosis of this disease is important. We present a young patient with CD and retroperitoneal non-organ neoplasm. Despite a thorough preoperative examination, the final diagnosis was established only after histological examination of surgical specimen. We discuss the diagnosis and surgical treatment of a patient with unicentric type of CD.

RESUMO

Phenotypic characteristics of alveolar macrophages in the bronchoalveolar lavage fluid as well as their ability to acquire the M1 and M2 phenotypes during in vitro culturing with reprogramming factors were studied in rats with modeled diet-induced metabolic syndrome. A decrease in the number of alveolar macrophages with the M1 phenotype was found in animals with metabolic syndrome. The factors of metabolic syndrome do not affect phenotypic plasticity of cells in culture, but under the action of M2 reprogramming factors, the cells demonstrate a wide range of phenotypic plasticity by the CD80 and CD206 markers. The consistently high level of production of IL-6 and IL-10 by macrophages during culturing under different conditions indicates functional rigidity of the cells, which is probably a consequence of in vivo predetermined functional phenotype of these cells against the background of metabolic disorders.

RESUMO

AIM: To evaluate the possibilities of textural analysis of 3D models in differentiating the degree of nuclear dysplasia of the clear cell renal cell carcinoma (ccRCC). MATERIALS AND METHODS: The specimens after surgical treatment of 190 patients with ccRCC were analyzed. In all cases, nephron-sparing surgery (NSS) was performed through laparoscopic access. The clinical characteristics were evaluated, including age, gender, tumor localization (side, surface and segments), absolute tumor volume, Charlson comorbidity index, body mass index, nephrometry scores (RENAL, PADOVA, C-index). Patients were divided into 2 groups. In group 1, there were 119 patients with the ccRCC of Grade 1 or 2, while group 2 consisted of 71 patients with ccRCC of Grade 3 and 4. All patients underwent 3D virtual planning of procedure using the 3D modeling program "Amira". At the first stage, two experienced radiologists performed manual segmentation of 3D models of kidney parenchyma tumors. At the second stage, the tumor shape was analyzed with a mathematical calculation of three indicators and more than 300 textural features of statistics of types 1-2 were extracted. Further, an intellectual analysis was carried out. For the evaluation of tumor grade according to Furman system, the classification problem was solved using the machine learning algorithm Stochastic Gradient Descent and cross-validation k=5. RESULTS: The accuracy of classification for the two groups of Grade 1 or 2 and Grade 3 or 4 on the F1 metric was 72.2. To build the model, the following parameters were selected: the absolute tumor volume, the Charlson comorbidity index, "Energy", the first quartile and the second decile of the pixel intensity distribution. CONCLUSION: The texture analysis of 3D models for the prediction of Fuhrman grade in ccRCC demonstrated satisfactory quality for two groups of Grade 1 or 2 and Grade 3 or 4 nuclear dysplasia.

RESUMO

We present diagnosis and complex minimally invasive surgical treatment of a patient with long-standing neuroendocrine tumor of the upper gastrointestinal tract. We followed-up a 50-year-old female patient after endoscopic resection of polypoid neoplasm of the stomach for 2 non-organ retroperitoneal neoplasms in the area of hepatogastric ligament. After a comprehensive examination and minimally invasive surgery including laparoscopic resection of retroperitoneal neoplasms, immunohistochemical examination, PET-CT and targeted endoscopic ultrasound of the stomach, we diagnosed a highly differentiated gastric neuroendocrine tumor with metastases into lymph nodes of hepatogastric ligament.

RESUMO

Objective: To explore the causes and summarize the treatment experience for clinically relevant delayed gastric emptying(DGE) after laparoscopic pancreaticoduodenectomy(LPD). Methods: The clinical data of 1 000 patients who underwent LPD in the Department of Liver Transplantation and Hepatobiliary Surgery,Shandong Provincial Hospital Affiliated to Shandong First Medical University between March 2017 and September 2022 was retrospectively collected. There were 640 males and 360 females,with an age of (60.1±11.4)years(range: 13 to 93 years),and 590 patients were older than 60 years. Depending on the severity of DGE,patients were divided into a clinically relevant DGE group and a 0/A grade DGE group. The comparison between the two groups was performed by the χ2 test,Fisher's exact probability method,t test or the rank sum test,and the effects of various treatment strategies for clinically relevant DGE were evaluated. Results: LPD was conducted successfully in all 1 000 patients,with a surgical time of (344.8±103.6)minutes(range:160 to 450 minutes) and intraoperative blood loss (M(IQR)) of 100 (150) ml(range:50 to 1 000 ml). A total of 74 patients(7.4%) developed clinically relevant DGE. Compared to those in the 0/A grade DGE group,patients in the clinically relevant DGE group had a higher preoperative body mass index of ((24.9±3.5)kg/m2 vs. (23.9±3.3)kg/m2,t=-2.419,P=0.016),more postoperative bile leakage(51.4%(38/74) vs. 10.8%(100/926)),pancreatic fistula(59.5%(44/74) vs. 22.9%(212/926)),abdominal infection(74.3%(55/74) vs.14.6%(135/926)),and abdominal bleeding(43.2%(32/74) vs. 11.3%(105/926))(all P<0.05). Among these patients,10 cases(13.5%) received enteral nutrition treatment,22 cases(29.7%) received parenteral nutrition treatment,and 42 cases(56.8%) received a combination of enteral and parenteral nutrition treatment. The time for patients to return to a normal diet was 21(14)days (range: 8 to 85 days). Compared to those who received only enteral(23.5(27.0)days) or parenteral nutrition treatment(15.5(11.0)days),patients who received a combination of enteral and parenteral nutrition treatment(25.5(31.0)days) had a longer time to return to a normal diet (Z=20.019,P<0.01). Among the 60 patients who developed secondary DGE,48 cases(80.0%) received ultrasound-guided puncture and drainage treatment,while 12 cases(20.0%) only received anti-infection treatment. The patients in the non-puncture drainage group had a longer time to return to a normal diet than those in the puncture drainage group (26.5(12.5)days vs. 20.0(11.0)days, Z=-2.369,P=0.018). Conclusions: Patients with clinically relevant DGE after LPD had a higher proportion of postoperative complications such as pancreatic fistula,biliary fistula and abdominal infection. A combination of enteral and parenteral nutrition treatment is needed for patients with a long-term course of DGE."Smooth" drainage and ani-infectious therapy could contribute to the recovery of DGE.

RESUMO

Incidence of adenomas of the major duodenal papilla has increased in recent years due to widespread endoscopic screening. These adenomas require resection due to high risk of malignant transformation. Currently, minimally invasive endoscopic interventions are often considered as an alternative to surgical treatment. Combination of major duodenal papilla neoplasms with choledocholithiasis and bile duct strictures are particularly difficult for endoscopic treatment. A 56-year-old patient underwent complex endoscopic treatment for a large adenoma of the major duodenal papilla spreading to duodenal walls and distal segment of the common bile duct combined with choledocholithiasis and stricture of the common bile duct. The patient underwent complex minimally invasive treatment with endoscopic lithoextraction, fragment-by-fragment removal of the neoplasm with intra-ductal ablation of residual adenomatous tissue and subsequent staged biliary stenting for the stricture of the common bile duct, as well as stenting of the main pancreatic duct for prevention of pancreatitis. An integrated approach to the treatment of a patient with a large adenoma of the major duodenal papilla, choledocholithiasis and stricture of the common bile duct provided clinical success without complications and the need for long-term rehabilitation.
