Fabrication of a modified bacterial cellulose with different alkyl chains and its prevention of abdominal adhesion.

Abdominal hernia mesh is a common product which is used for prevention of abdominal adhesion and repairing abdominal wall defect. Currently, designing and preparing a novel bio-mesh material with prevention of adhesion, promoting repair and good biocompatibility simultaneously remain a great bottleneck. In this study, a novel siloxane-modified bacterial cellulose (BC) was designed and fabricated by chemical vapor deposition silylation, then the effects of different alkyl chains length of siloxane on surface properties and cell behaviors were explored. The effect of preventing of abdominal adhesion and repairing abdominal wall defect in rats with the siloxane-modified BC was evaluated. As the grafted alkyl chains become longer, the surface of the siloxane-modified BC can be transformed from super hydrophilic to hydrophobic. In vivo results showed that BC-C16 had good long-term anti-adhesion effect, good tissue adaptability and histocompatibility, which is expected to be used as a new anti-adhesion hernia repair material in clinic.

The authors present successful treatment of diffuse purulent peritonitis using a combination of 'open abdomen' technology and VAC therapy. This approach reduces abdominal inflammation and intra-abdominal pressure. Combination of 'open abdomen' technology and VAC therapy provides effective control of inflammation and stabilization of patients with purulent peritonitis.

Reconstrução mamária com TRAM: avaliação tomográfica abdominal / Breast reconstruction with TRAM: abdominal tomographic evaluation

Introdução: O retalho transverso do músculo reto abdominal (TRAM) é um método de reconstrução mamária com bons resultados estéticos e dispensa o uso de próteses de silicone para melhor contorno corporal. Foi originalmente descrito por Holmstrom em 1979, como uma elipse de pele e gordura com base em um músculo isolado no seu pedículo vascular. A reconstrução sistematizada do defeito da parede instalado após a transposição do retalho com o uso de tela de polipropileno foi descrita em estudo prévio por Cunha. O artigo tem como objetivo avaliar as alterações na parede abdominal, após a sistematização da colocação da tela de polipropileno durante a cirurgia de reconstrução com TRAM. Método: É um trabalho de coorte retrospectivo que avalia as possíveis alterações da parede abdominal de pacientes submetidos ao retalho TRAM com tomografia computadorizada de abdome pré e pós-operatórias. Resultados: Foi evidenciada uma redução do tamanho da cavidade abdominal de, em média, 14,5% e 14,2% na espessura da parede abdominal submetidas ao TRAM. A maior redução da espessura da parede abdominal foi de um paciente submetido ao retalho bipediculado, com 50,7%. As complicações apresentadas foram hérnia umbilical, seroma tardio, fibrose peritela e granuloma de fio. Conclusão: Nesse estudo, a tomografia após a cirurgia demonstrou a redução no volume da cavidade abdominal e espessura da parede abdominal, o que não influenciou estatisticamente no aparecimento de hérnia abdominal, abaulamentos, extrusão da malha ou outras deformidades.

Introduction: The transverse rectus abdominis muscle flap (TRAM) is a method of breast reconstruction with good aesthetic results and does not require the use of silicone implants for better body contouring. It was originally described by Holmstrom in 1979 as an ellipse of skin and fat based on an isolated muscle on its vascular pedicle. The systematic reconstruction of the wall defect installed after flap transposition using polypropylene mesh was described in a previous study by Cunha. The article aims to evaluate changes in the abdominal wall, after the systematization of polypropylene mesh placement during TRAM reconstruction surgery. Method: This is a retrospective cohort study that evaluates possible changes in the abdominal wall of patients undergoing the TRAM flap with preand postoperative abdominal computed tomography. Results: A reduction in the size of the abdominal cavity of, on average, 14.5% and 14.2% in the thickness of the abdominal wall subjected to TRAM was evidenced. The greatest reduction in abdominal wall thickness was in a patient who underwent a bipedicled flap, with 50.7%. The complications presented were umbilical hernia, late seroma, perithellal fibrosis, and thread granuloma. Conclusion: In this study, tomography after surgery demonstrated a reduction in the volume of the abdominal cavity and thickness of the abdominal wall, which did not statistically influence the appearance of abdominal hernia, bulging, mesh extrusion, or other deformities.

Morphofunctional Alteration of Mesenteric Lymph Nodes in the Inflammation of the Abdominal Cavity.

This paper provides data regarding the ratios of the functional structures of lymph nodes after inflammation in the abdominal organs. Lymph systems, including lymph nodes, function as filters of tissues and tissue fluids and are places of origin and lymphocyte production for normal physiological functions. They display specific morphological and functional responses in reaction to endogenous and exogenous substances. The morphological pattern of the mesenteric lymph node in experimental rat groups reflects a decrease in its immune function due to the processes of inflammation in the abdominal cavity. These processes work together with the associated organs and their involvement in the abdominal lymph nodes, in which there are discharges of the structure of the paracortical zone under conditions of reduced lymphogenic processes, according to the decrease in the size of the paracortex and the ratios of lymphoid nodes with and without germinal centers. Histological and morphometric analyses show changes in the mesenteric lymph node. These analyses are characterized by changes in the cortical and medullary substances, while the proportion of the cortical structure decreases. We also noted an increase in the number of macrophages in the lymphoid nodes and cerebral sinus, as well as a decrease in the number of mature plasmocytes, the paracortex, and the pulp strands. These changes indicate immunosuppressive effects on the lymph node. Under the conditions of inflammation, the formation of a mixed immune response occurs.

Clinicopathologic profile of intra-abdominal follicular dendritic cell sarcoma: A study of three cases with a literature review.

Follicular dendritic cell sarcoma (FDCS) is a rare tumor, which mainly originates from follicular dendritic cells (FDCs) in the lymph nodes. Sometimes FDCS can arise from outside the lymph nodes. FDCS is an extremely rare malignant tumor in intraperitoneal or retroperitoneal tissue. We gathered the detailed clinical data of three patients diagnosed with FDCS in the abdomen. The clinical observations and histopathologic and immunohistochemical features of FDCS were analyzed. The patients included two men and one woman aged 55 ~ 61 years old. The mesentery of the small intestine and colon was involved in case 1, spleen in case 2, and retroperitoneal tissues in case 3. Two patients presented with abdominal masses, and one presented with no obvious symptoms. Histology showed ovoid to spindle neoplastic cells arranged in fascicles and storiforms with inflammatory infiltrate as well as whorled patterns in some areas. Immunohistochemical staining was positive for CD21, CD23, CD35, and SSTR2. FDCS exhibits no characteristic clinical manifestations. Morphologically, FDCS can have overlapping features with many other entities, leading to misdiagnosis. The use of histopathology supplemented with FDC markers, such as CD21, CD23, and CD35, is useful for diagnosis and differential diagnosis.

Removal of a guide-wire sliding into abdominal cavity via transgastric natural orifice transluminal endoscopic surgery: A case report.

BACKGROUND: Guidewire slippage into the peritoneal cavity during clinical operations is extremely rare. Therefore, this paper aims to report a successful case of guidewire removal using transgastric natural orifice transluminal endoscopic surgery (NOTES). The goal is to enhance physicians' understanding of the management plan for this unique scenario and provide a valuable reference for clinical practice. CASE SUMMARY: A 64-year-old man presented with abdominal distension and was diagnosed with cirrhosis combined with massive ascites. To proceed with treatment, the patient underwent ultrasound-guided peritoneal puncture and underwent catheterization and drainage. Unfortunately, a 0.035-inch guidewire slipped into the abdominal cavity during the procedure. Following a comprehensive evaluation and consultation by a multidisciplinary team, the guidewire was successfully removed using NOTES. CONCLUSION: This case highlights the potential consideration of transgastric NOTES removal when encountering a foreign body, such as a guidewire, within the abdominal cavity.

Molecular identification of sparganum of Spirometra mansoni isolated from the abdominal cavity of a domestic cat in Vietnam.

Cats normally play a role of the definitive host in which the plerocercoid (sparganum), the second larval form of Spirometra spp., develops into an adult in the intestines. However, some cases of cats with visceral or subcutaneous sparganosis were sporadically reported worldwide. We herein documented the discovery of a sparganum in abdominal cavity of a domestic cat during a surgery of dystocia. The larva was molecularly identified as Spirometra mansoni, belonging to Type I, that was recently misidentified to be S. erinaceieuropaei in several Asian countries. This is the first report for sparganum of S. mansoni in the cat. The future study is necessary to provide further insights into the species of Spirometra causing sparganosis and spirometrosis in humans and other animals.

Textiloma intrabdominal incidental

Introducción: Los textilomas son cuerpos extraños originados a partir del material quirúrgico textil, olvidado durante una intervención quirúrgica. Son poco frecuentes. Su forma de presentación clínica puede ser aguda o crónica y se manifiestan meses o años después de la operación quirúrgica original. Objetivos: Presentar un caso poco frecuente de textiloma intrabdominal, sus manifestaciones clínicas, diagnóstico y tratamiento. Caso clínico: Paciente masculino de 39 años de edad, con antecedentes de haber sido operado hace 14 años de úlcera duodenal sangrante, asintomático hasta la fecha en que se estudió por síntomas digestivos. Como único elemento positivo al examen físico se constató dolor a la palpación profunda en epigastrio. Durante la endoscopía se diagnosticó una lesión subepitelial gástrica. En la tomografía con doble contraste de abdomen se corroboró una lesión de aspecto tumoral en la curvatura mayor del estómago, dependiente de su pared. Se realizó ultrasonido endoscópico mediante el cual se diagnosticó un tumor mesenquimal del mesenterio, sin poder descartar la posibilidad de un tumor del estroma gastrointestinal gástrico. Se realizó exéresis del tumor. El estudio anatomopatológico informó textiloma. Conclusiones: Los textilomas son accidentes quirúrgicos con consecuencias perjudiciales para la vida del paciente si no se procede rápidamente. Son el resultado de la iatrogenia durante una intervención quirúrgica y lo más importante es su prevención.

Introduction: Textilomas are foreign bodies originating from the textile surgical material, forgotten during a surgical intervention. They are rare. Its clinical presentation can be acute or chronic, manifesting months or years after the original surgical operation. Objectives: To present a rare case of intra-abdominal textiloma, its clinical manifestations, diagnosis and treatment. Clinical case: A 39-year-old male patient with a history of been operated on 14 years ago for a bleeding duodenal ulcer; asymptomatic until the date he was studied for digestive symptoms. The only positive element in the physical examination was pain on deep palpation of epigastrium. During endoscopy, a gastric subepithelial lesion was diagnosed. The double-contrast abdominal tomography confirmed a tumor-like lesion at the greater curvature of the stomach, depending on its wall. An endoscopic ultrasound was performed, through which a mesenchymal tumor of the mesentery was diagnosed, without being able to rule out the possibility of a gastric gastrointestinal stromal tumor. Excision of the tumor was performed. The anatomopathological study reported a textiloma. Conclusions: Textilomas are surgical accidents with detrimental consequences for the patient's life if not proceeded quickly. They are the result of iatrogenesis during a surgical intervention and the most important thing is their prevention.

Primary intra-abdominal paraganglioma: A case report.

BACKGROUND: Paragangliomas are rare neuroendocrine tumors. We hereby report a case of a localized paraganglioma found in the abdominal cavity, and review the relevant literature to improve the understanding of this disease. CASE SUMMARY: A 29-year-old Chinese female patient was referred to our hospital due to an abdominal mass found on physical examination. Imaging revealed a mass in the left upper abdomen, suggestive of either a benign stromal tumor or an ectopic accessory spleen. Laparoscopic radical resection was subsequently performed, and histopathological analysis confirmed the diagnosis of a paraganglioma. The patient was followed up 3 months post-operation, and reported good recovery with no metastasis. CONCLUSION: Radical resection can effectively treat intra-abdominal paragangliomas, with few side effects and low recurrence risk. In addition, early and accurate diagnosis and timely intervention are essential for the prognosis of this disease.

Non-traumatic spontaneous abdominal haemorrhage.

Spontaneous abdominal hemorrhage is defined as intra-abdominal hemorrhage from a non-traumatic cause. It is a challenging clinical situation and in most cases the diagnosis is made on the basis of imaging findings. CT is the technique of choice for the detection, localization and extension of bleeding. Objective is to review the main imaging findings expected in spontaneous abdominal hemorrhage as well as its main etiologies.

Complications after abdominal surgery.

Complications after abdominal surgery are often seen in emergency departments. Many postoperative complications (e.g., infections, abscesses, hematomas, and active bleeding) are common to all types of surgery; others are specific to different types of surgery. Computed tomography (CT) is the technique normally used to diagnose postoperative complications. This article reviews the changes that occur after some of the most common abdominal interventions that can be mistaken for pathological processes, the findings that can be considered normal after surgical intervention, and the most common early complications. It also describes the optimal protocols for CT studies depending on the different types of complications that are suspected.

Unusual mesentery metastasis of differentiated thyroid cancer: a case report.

Distant metastases of well-differentiated thyroid cancers (WDTCs) to bone and lungs are well known, while intra-abdominal, mesenteric metastases are very rare. Herein, we report a case of intra-abdominal, mesenteric metastasis of WDTC. A 62-year-old man underwent thyroid lobectomy for follicular thyroid cancer. One year later, lung metastasis was observed. The patient simultaneously underwent lung wedge resection and complete thyroidectomy. Eleven years later, serum thyroglobulin level was elevated. On the work-up study, a metastatic lesion in the lungs and a mass in the mesentery were identified. Two lesions of the lung and mesentery were surgically resected. The mass in the mesentery was pathologically diagnosed as metastatic WDTC.

Clinicopathological features of intraabdominal bronchogenic cyst: an analysis of 8 cases / 中华全科医师杂志

Objective:To analyze the clinicopathological features of intraabdominal bronchogenic cyst.Methods:The clinical data of 8 patients with intraabdominal bronchogenic cyst admitted in 3 Grade-A tertiary hospitals in Yunnan province between 2014 and 2023 were retrospectively analyzed. The clinical and pathological features, diagnosis, treatment and prognosis of intraabdominal bronchogenic cyst were reviewed.Results:There were 1 male and 7 females with an mean age of 45±12 years (21-65 years). Two patients presented with abdominal pain and 5 asymptomatic patients were found during physical examination. The cysts were located in retroperitoneum in 4 cases, located between the pancreas tail, spleen and the posterior wall of the stomach in 2 cases, located in the posterior wall of the stomach in 1 case, and located close to left adrenal gland in 1 case. Two patients had elevated tumor markers, while tumor markers in the remaining 6 cases were normal. Seven cases underwent laparoscopic complete cyst resection and 1 case had open surgical resection. The wall of most cysts were lined with respiratory epithelium and composed of goblet cells or pseudostratified ciliated columnar epithelium. The wall of cysts was composed of fibrous connective tissue or smooth muscle bundles, and the cavity contained serous mucous glands. Two cases showed cartilage tissue and one showed the infiltration of large number of inflammatory cells. The mean follow-up time was 31±32 months (range 5-107 months), and no recurrence or metastasis was found during the follow-up.Conclusions:Abdominal bronchogenic cyst is often found in adulthood, and most cases are symptomatic and found during physical examination. The diagnosis mainly depends on pathological examination, and tumor markers are not specific for its diagnosis. Surgery is the best way for treatment.

Abdominal bronchogenic cyst: A rare case report.

BACKGROUND: Bronchogenic cysts are cystic masses caused by congenital abnormal development of the respiratory system, and usually occur in the pulmonary parenchyma or mediastinum. CASE SUMMARY: A rare case of a bronchogenic cyst discovered in the abdominal cavity of a 35-year-old man is reported. Physical examination found a space-occupying lesion in the patient's abdomen for 4 d. Laparoscopic exploration found the cyst tightly adhered to the stomach and its peripheral blood vessels; therefore, intraoperative laparotomy was performed. The cystic mass was resected en bloc with an Endo-GIA stapler. The final postoperative pathological diagnosis confirmed an abdominal bronchogenic cyst. CONCLUSION: This is a rare case of a bronchogenic cyst that was discovered within the abdominal cavity of a male patient. The cyst is easily confused with or misdiagnosed as other lesions. Therefore, it is necessary to distinguish abdominal bronchogenic cyst from gastrointestinal stromal tumor, Meckel's diverticulum, enteric duplication cyst, or lymphangioma. Although computer tomography and magnetic resonance imaging were the primary diagnostic approaches, endoscopic ultrasound-guided fine-needle aspiration could assist with clarification of the cytological or histopathological diagnosis before surgery.

Diagnóstico, manejo y tratamiento de pacientes con peritonitis secundaria en una unidad de cirugía general / Diagnosis, management and treatment of patients with secondary peritonitis in a general surgery unit

La peritonitis es una inflamación aguda o crónica del peritoneo que generalmente tiene un origen infeccioso. Existen varios tipos, siendo la de tipo secundario la más frecuente. El término peritonitis secundaria se define como la inflamación localizada o generalizada de la membrana peritoneal causada por infección polimicrobiana posterior a la ruptura traumática o espontánea de una víscera o secundaria a la dehiscencia de anastomosis intestinales. Esta entidad se caracteriza por la presencia de pus en la cavidad peritoneal o de líquido; que, en el estudio microscópico directo, contiene leucocitos y bacterias. El tratamiento de esta patología constituye una urgencia y puede ser de tipo clínico y/o quirúrgico. El objetivo del manejo operatorio se basa en identificar y eliminar la causa de la infección, recoger muestras microbiológicas, realizar una limpieza peritoneal y prevenir la recidiva. El tratamiento clínico se ocupa de las consecuencias de la infección mediante la reanimación perioperatoria y el tratamiento antibiótico1. A pesar de los avances en diagnóstico, procedimientos quirúrgicos, terapia antimicrobiana y cuidados intensivos, la mortalidad asociada con la peritonitis secundaria grave es aún muy alta. El pronóstico y el manejo oportuno representan la clave para mejorar la sobrevida y reducir la mortalidad asociada a infecciones intraabdominales extensas2. Es importante establecer lineamientos en cuanto al diagnóstico, manejo antibiótico y pautas de tratamiento quirúrgico para disminuir la morbilidad y mortalidad asociada a esta enfermedad. Palabras clave: Peritonitis; Peritoneo; Cavidad Abdominal/cirugía; Cavidad Peritoneal; Líquido Ascítico/patología; Procedimientos Quirúrgicos Operativos.

Peritonitis is an acute or chronic inflammation of the peritoneum that generally has an infectious origin. There are several types, with secondary peritonitis being the most frequent. The term secondary peritonitis is defined as localized or generalized inflammation of the peritoneal membrane caused by polymicrobial infection following traumatic or spontaneous rupture of a viscus or secondary to dehiscence of intestinal anastomoses. This entity is characterized by the presence of pus in the peritoneal cavity or fluid which, on direct microscopic examination, contains leukocytes and bacteria. The treatment of this pathology constitutes an emergency and can be clinical and/or surgical. The aim of operative management is based on identifying and eliminating the cause of the infection, collecting microbiological samples, performing peritoneal cleansing and preventing recurrence. Clinical management deals with the consequences of the infection by perioperative resuscitation and antibiotic treatment1 . Despite advances in diagnosis, surgical procedures, antimicrobial therapy and intensive care, mortality associated with severe secondary peritonitis is still very high. Prognosis and timely management represent the key to improving survival and reducing mortality associated with extensive intra-abdominal infections2. It is important to establish guidelines for diagnosis, antibiotic management and surgical treatment guidelines to reduce the morbidity and mortality associated with this disease.

New record of Tylodelphys metacercariae (Diplostomidae) from Perccottus glenii (Odontobutidae) and their phylogenetic assessment.

Metacercariae of Tylodelphys sp. were found in the abdominal cavity of the Chinese sleeper (Perccottus glenii) collected in Liaoning Province and Inner Mongolia Autonomous Region of China. The sequences of the mitochondrial cox1 gene and ribosomal ITS1-5.8S rDNA-ITS2 region were obtained and used for molecular identification and phylogenetic assessment of this parasite species. Results of phylogenetic analyses based on ITS and cox1 markers showed that the metacercariae of Tylodelphys sp. ex P. glenii from China were conspecific with specimens of Tylodelphys sp. collected by Sokolov et al. (2013) from the same fish-host species captured earlier in West Siberia, Russia. The examined Tylodelphys sp. ex. P. glenii is the only member of the genus whose metacercariae parasitise the abdominal cavity of fish in northern Eurasia. Tylodelphys sp. ex P. glenii clustered with T. darbyi, T. immer, T. podicipina, and Tylodelphys sp. of Soldánová et al., 2017 based on mitochondrial DNA markers, and with T. darbyi, T. immer, T. kuerepus, and T. schreuringi using nuclear DNA markers.
