Introducción: El angioma de células litorales es un nuevo subtipo de tumor vascular, el cual ha sido reportado con poca frecuencia en todo el mundo. Se asocia con neoplasias malignas viscerales y otras condiciones inmunitarias. Caso clínico: Varón caucásico de 70 años con antecedentes de síndrome mielodisplásico de 6 años de evolución, que fue investigado por esplenomegalia y pancitopenia. Los exámenes radiológicos e histopatológicos revelaron un angioma de células litorales y se realizó una esplenectomía abierta. El paciente tuvo una recuperación posoperatoria sin incidentes. Conclusión: El angioma de células litorales es un tumor raro, con presentación atípica y frecuentemente asociado con otras neoplasias malignas o condiciones inmunitarias. El diagnóstico es un desafío y, hasta ahora, la esplenectomía es el tratamiento estándar.

We present a case of a 44-year-old male with chronic hepatitis B that visited the Emergency Department due to epigastric pain after a liver biopsy. The ultrasonography revealed signs of bleeding in the bile ducts. and angiography visualized an arterioportal fistula. Selective right hepatic artery branch embolization was performed, and the bleeding was controlled. Although, the clinical picture was initially improved, the patient presented later with acute abdomen, obstructive jaundice and fever. The patient underwent cholecystectomy with bile duct exploration and placement of a Kehr's T tube in the common bile duct. The postoperative course was uneventful. We also review the relevant literature concerning arterioportal fistula manifested as hemobilia as well as acute cholecystitis occurring after hemobilia. [ABSTRACT FROM AUTHOR]

Background/Aims: Hepatic injury caused by ischemia/reperfusion (I/R) is a clinical problem associated with major liver surgery. Among other flavonoids, apigenin has shown a promising effect on I/R cases. In this study, we have investigated the effects of apigenin after liver I/R injury in rats. Materials and Methods: Forty eight rats were randomized into the following eight groups: (1) Control-sham group: rats subjected to the surgical procedure, except for liver I/R; (2) DMSO group: rats subjected to surgery, except for liver I/R given the apigenin solvent dimethyl-sulfoxide intraperitoneally; (3) C60 group; (4) C120 group; (5) C240 group: rats underwent liver ischemia for 45 min followed by reperfusion for 60 min, 120 min, and 240 min; (6) AP60 group; (7) AP120 group; (8) AP240 group: rats underwent liver ischemia for 45 min, and then given apigenin (5 mg) intraperitoneally followed by reperfusion for 60 min, 120 min, and 240 min. Reverse transcription polymerase chain reaction was performed on liver tissues to measure BCL-2/BAX expression, enzyme-linked immunosorbent assay to measure M30/M65 and ICAM-1. Immunohistochemistry was used to identify M30 biomarker in liver tissues. Statistical Analysis: Quantitative variables were tested by Kolmogorov--Smirnov test, repeated measures analysis of variance/Friedman test. Gene levels were assessed by Student's t-test/Mann--Whitney U-test. Results: BCL-2 levels were significantly higher in I/R apigenin groups than in I/R control groups. BAX levels were lower in the AP240 group than in C240 group. Prolongation of reperfusion resulted in increased activation of M30. ICAM-1 levels were lower in the AP240 group than in C240 group. Conclusions: Apigenin seems to inhibit the process of apoptosis and ameliorate the hepatic I/R injury. [ABSTRACT FROM AUTHOR]

Objectives: Complex abdominal wall reconstruction cases constitute a challenging issue, with high morbidity and mortality rates. Materials and methods: A young trauma patient presented abdominal dehiscence after multiple laparotomies. The fascial defect was managed with the use of a biological mesh, while initially primary wound closure was attempted. Due to cutaneous dehiscence, the use of negative pressure wound therapy was decided. Results: Granulation tissue formation was noticed on the eighth day while complete wound closure was achieved after 57 days. Conclusions: In conclusion, the combined use of biological mesh and negative pressure wound therapy is feasible in the management of complicated abdominal defects. [ABSTRACT FROM AUTHOR]

Objective: The aim of the present study was to evaluate the changes caused by intravenous administration of regulatory peptides, bombesin (BBS) and neurotensin (NT), on gastric secretion, serum gastrin, and plasma levels of bombesin-1ike immunoreactivity (BLI) and neurotensin. Materials and methods: Fourteen dogs underwent an upper gastrointestinal tract operation and a Pavlov pouch for the concentration of gastric fluids was formed. The experimental animals were divided into two groups. Peptides were given one month after the second operation and after fasting for 12 hours. In group A, the effects of BBS were studied after a rapid 1 µg/kg body weight dose and a slow 30΄ 0.5 μg/kg body weight dose administration intravenously. Correspondingly to group B the effects of NT were studied in the same way. Results: The rapid intravenous infusion of BBS caused a very significant increase in gastrin levels, BLI in plasma, volume and HCl of the gastric fluids. The same results, plus a significant decrease in gastric pH, were observed following slow intravenous infusion of BBS. Concerning the NT, rapid administration caused a significant decrease in the volume of gastric fluids. Slow NT administration of caused a significant reduction in gastric fluid volume and in HCl. On the contrary, pH was significantly increased. Conclusion: Bombesin increases plasma gastrin levels and HCl secretion. Neurotensin administration causes a decrease in HCl secretion without affecting gastrin levels in plasma. [ABSTRACT FROM AUTHOR]

Testicular cancer is the solid tumor with the greatest incidence in men between 15 and 44 years old. Its main histological type is germ cell tumor, that is divided into seminomatous and non-seminomatous tumors. Seminoma, consisting 55% of testicular cancer, manifests in the fourth decade of men's life and a rare type of it is the anaplastic seminoma (5% to 15% of testicular seminoma). Diagnosis is based on clinical examination, testicular ultrasound, magnetic resonance imaging, tumor markers measurement and pathological examination, while treatment of choice is radical orchiectomy, with or without retroperitoneal lymphadenectomy, potentially followed by radiotherapy or chemotherapy. We present the case of a 36-year-old male patient, whose father suffered from anaplastic seminoma and visited the hospital due to a painless hydrocele. The testicle was swollen and hard on palpation, while cytological examination of the drained fluid detected neoplasm, potentially seminoma. Tumor markers measurement, as well as abdominal and pelvic computerized tomography scans, were evaluated and the patient was staged as IIA, according to the American Joint Commission on Cancer. Radical orchiectomy with high ligation of the seminal vesicle was performed and the pathological examination showed anaplastic testicular seminoma. Postoperatively, four cycles of chemotherapy with bleomycin, etoposide and platinum (BEP) were performed and no signs of recurrence were present after 1 year. In conclusion, anaplastic seminoma has a good prognosis and is suggested to be treated with radical orchiectomy, with or without retroperitoneal lymphadenectomy, potentially followed by radiotherapy or chemotherapy., Competing Interests: Conflict of interests: The authors declare no competing interests., (Copyright © 2022, Ioannidis O et al., Applied Systems and Discoveries Journals.)

Transdiaphragmatic intercostal hernia, in which the abdominal contents of the hernia protrude through the diaphragm and the thoracic wall defect. is a very rare type of hernia with only a few cases having been reported in the literature. That type of hernia is usually manifested in male patients after trauma, penetrating or blunt. It is frequently presented with a palpable thoracic mass and pain. The indicated treatment is surgery. We present the case of a 60-year-old female admitted to the hospital after a car accident and suffered multiple rib fractures (6th, 7th, 8th right ribs / 7th, 8th, 9th left ribs), as well as flail thorax, hemothorax bilaterally, left subcutaneous emphysema and swelling of soft tissues of the right lateral thoracoabdominal wall. CT scan revealed herniation of hepatic parenchyma and intestinal loops into the thorax. The patient was treated surgically, and his postoperative course was uneventful. We also review the relevant literature concerning this transdiaphragmatic, intercostal hernia and identify 42 cases. Transdiaphragmatic intercostal hernia is a rare condition, usually manifested in male patients after trauma, penetrating or blunt. It is frequently presented with a palpable thoracic mass and pain. The indicated treatment is surgery., Competing Interests: Conflict of interests: The authors declare no competing financial interests or conflicts of interest., (Copyright © 2021, Ioannidis O. et al., Applied Systems and Discoveries Journals.)

Aim: Growth hormone is known to affect healing on the postoperative patient. The aim of the present experimental study was to evaluate the effect of systematic infusion of growth hormone on the healing of colonic anastomoses in rats., Methods: Fourty Albino-Wistar male rats were randomly divided into two groups, a control group (CONTROL) and a growth hormone (GH) group. In both groups, an end-to-end colonic anastomosis was performed after segmental resection. In the CONTROL group, 1 cc saline was administered subcutaneously in the experimental animals' necks in two equal doses daily until the sixth postoperative day. In the GH group, rats were administered a growth hormone solution (2 mg/kg b.w.) in an amount of 1 cc subcutaneously in their necks in two equal doses daily until the sixth postoperative day. Rats were sacrificed on the seventh postoperative day. Anastomoses were resected and macroscopically examined. Bursting pressures were calculated and histological features were graded and hydroxyproline was evaluated., Results: No deaths or wound infections were observed until the sacrifice. Bodyweight was significantly increased in the GH group until the seventh postoperative day (p = 0.005). Bursting pressures (p = 0.0025), adhesion formation (p=0.0019), hydroxyproline concentrations (p = 0.007) were significantly higher in the GH group than in the control group. Also GH lead to decreased inflammation (p < 0.001), but increased neoangiogenesis (p < 0.001), fibroblast activity (p = 0.001) and collagen deposition (p < 0.001)., Conclusion: Growth hormone, when applied systematically in rats with colonic anastomoses, promotes their healing in rats. Therefore, the application of growth hormone in colonic anastomoses leads to better outcomes., Key Words: Adhesion, Bursting pressure, Collagen, Hydroxyproline, Inflammation, Neoangiogenesis.

Objective: Pancreaticoduodenectomy has been established as the treatment of choice for the management of benign and malignant lesions of the pancreatic head, and pancreaticojejunal or pancreaticogastric anastomosis seems to be the safer choice for the management of the pancreatic duct. However, in certain seldom, but still existing circumstances, pancreatic duct ligation or occlusion with a chemical substance is a valuable and viable alternative. The aim of the current study is to compare these two methods of occlusion of the pancreatic duct regarding the endocrine and exocrine function of the pancreas and its histopathology., Materials and Methods: 18 health mixed breed dog of both sexes were randomized in two groups: group A, in which the pancreatic duct was ligated and group B, in which the pancreatic duct was occluded with prolamine., Results: None of the animals presented postoperatively steatorrhea and significant body weight changes. Peripancreatic inflammation at sacrifice, inflammatory cell infiltration and edema of the pancreas on the 15th postoperative day and 30th postoperative day were milder after occlusion with prolamine than after ligation. Ligation of pancreatic duct lead to significantly greater hyperamylasemia than prolamine occlusion every day until the 15th. Mild hyperglycemia presented from the first to the fourth day in both groups, which was associated with a significant drop in insulin. Glucagon remained within the normal values at all times during the experiment. None of glucose, insulin and glucagon differed between groups., Conclusion: Prolamine occlusion of the pancreatic duct causes milder hyperamylasemia and less extensive inflammation both macroscopically and microscopically than ligation., Key Words: Pancreas, Pancreaticoduodenectomy, Hyperamylasemia.

Purpose: Chemotherapeutic factors are known to affect healing on the postoperative patient. The aim of the present experimental study was to evaluate the effect of intraperitoneal infusion of 5-fluorouracil, bleomycin and cisplatin on the healing of colonic anastomoses in rats., Methods: Forty Albino-Wistar male rats were randomly divided into two groups, a control and a chemotherapy (CT) group. In both, an end-to-end colonic anastomosis was performed. collagen, In the control group, 2cc saline was administered intraperitoneally during the operation and daily postoperatively until the sacrifice. In the CT group, rats were administered a solution of 5-fluorouracil (20mg/kg b.w.), bleomycin (4mg/kg b.w.) and cisplatin (0.7 mg/kg b.w.) in an amount of 2cc intraperitoneal intraoperatively and afterwards daily postoperatively until the seventh postoperative day when they were sacrificed. At sacrifice, adhesion presence was calculated and the anastomoses were resected and macroscopically examined. Bursting pressures were calculated and histological features were graded. Hydroxyproline concentrations were evaluated., Results: No deaths or wound infections were observed until sacrifice. Bodyweight was significantly decreased in the CT group (p=0.005). Bursting pressures (p=0.001) were significantly lower in the chemotherapy group, whereas adhesions were significantly increased (p=0.001). Hydroxyproline concentrations were not significantly different (p=0.401). All histological parameters appeared significantly decreased in the CT group: inflammation (p<0.008), neoangiogenesis (p<0.001), and fibroblast activity (p=0.001) and collagen deposition (p<0.001)., Conclusion: The use of chemotherapeutic agents had negative effects on the healing process of colonic anastomosis in rats. The decreased inflammatory response depicts in more frequent anastomotic dehiscence, ruptures and bodyweight loss postoperatively., Key Words: Adhesion, Bursting pressure, Collagen, Hydroxyproline, Inflammation, Neoangiogenesis.
