Unusual Cause of Intestinal Obstruction: Left Paraduodenal Hernia
Internal intestinal hernia has been defined as bulging of the intestines through a normal or an abnormal peritoneal or mesenteric opening. Paraduodenal hernias comprise 30%–53% of all internal intestinal herniations and account for 0.2%–0.9% of all bowel obstructions. In this paper, we aimed to present a male patient of 42 years of age who developed intestinal obstruction due to left paraduodenal hernias. Left paraduodenal hernia should be taken into consideration in the differential diagnosis in patients of relatively younger ages with no prior abdominal surgery who frequently have bowel obstruction episodes
Hydatid Cyst of the Adrenal Gland: Is Radical Surgery Necessary for Recurrent Hydatid Disease?
Hydatid cyst disease caused by E. granulosus is a zoonotic disease that may involve many body tissues and organs, mainly liver. Adrenal glands are rarely involved even in regions where hydatid cyst disease is endemic. A limited number of studies have been reported on adrenal gland involvement by hydatid cyst disease. Herein, we aimed to report a recurrent case of adrenal hydatid cyst that was misdiagnosed as a hepatic hydatid cyst. A 16-year-old boy with a history of partial cyst excision and evacuation for perforated adrenal hydatid cyst disease three years ago presented to our outpatient clinic with nonspecific abdominal pain. Ultrasonography and computed tomography showed a lesion with an approximate size of 70 × 70 mm compatible with a hydatid cyst, which originated from the segment 5-6 of the liver and extended to the posterior-inferior direction. A surgical intervention was scheduled after a 2-week prophylactic albendazole treatment. During laparotomy using the old incision, it was noted that the cystic lesion that reportedly located in liver was actually a recurrent right adrenal cyst. As dense adhesions existed, the cystic lesion was excised en bloc with the right adrenal gland. As the lesion was totally removed without getting ruptured, albendazole was not administered at the postoperative period. No recurrence was observed at one-year follow-up
Actinomyces-induced inflammatory myofibroblastic tumor of the colon: A rare cause of an abdominal mass Akbulut et al. inflammatory myofibroblastictumor due to actinomyces spp
AbstractIntroductionInflammatory myofibroblastic tumors (IMFTs) are neoplastic lesions that are either benign or have low-grade malignancy potential. Although the etiopathogenesis is not entirely clear, many factors play a role in their development, including trauma, autoimmune disorders, and infectious and inflammatory processes. However, IMFTs caused by Actinomyces spp. infection are rare, with a limited number of cases reported in the literature.Presentation of caseA 30-year-old woman was admitted to our clinic with abdominal pain and a palpable abdominal mass. Contrast-enhanced computed tomography revealed a tumoral lesion (11×10×7cm) in the right colon. A right hemicolectomy and ileocolic anastomosis were performed, during which almost complete obstruction of the lumen by the 7.5×7.0×5.0cm tumor was observed. Histopathology and immunohistochemical findings revealed that the tumor was consistent with an IMFT that developed from an Actinomyces infection. The patient was then placed on amoxicillin and doxycycline therapy.ConclusionThis case demonstrates that the development of IMFT secondary to actinomycosis is difficult to predict in the preoperative period. Once an exact diagnosis is confirmed by histopathologic examination, affected patients should receive prolonged antibiotherapy
Transmural migration of a surgical compress into the stomach after splenectomy: a case report
A surgical compress retained in the abdominal cavity following surgery is a serious problem. Here, we describe a 33-year-old female who was admitted with abdominal pain, vomiting, no passage of gas or feces, and abdominal distension for 3 days. She had a splenectomy at another medical center 4 years previously. An upright plain abdominal film revealed small bowel obstruction with marked small bowel air-fluid levels. The physical examination revealed muscular guarding and rebound tenderness in the periumbilical region. Therefore, a laparotomy was performed. A surgical compress was removed at enterotomy and the final diagnosis was gossypiboma. Because a retained surgical compress may lead to medicolegal problems, it is important to count the material used before and after a surgical procedure to reduce the risk of this problem
Gastric outlet obstruction caused by focal nodular hyperplasia of the liver: A case report and literature review
AbstractINTRODUCTIONHere, we present a case of gastric outlet obstruction due to focal nodular hyperplasia of the liver.PRESENTATION OF CASEA 23-year-old female presented to our emergency clinic with nausea, vomiting, and abdominal pain. Endoscopy showed that the prepyloric region of the stomach was externally compressed by a lesion. Computed tomography and magnetic resonance imaging revealed a 70mm solid mass originating from the liver, extending caudally in an exophytic manner, and compressing the stomach. Laparotomy revealed an irregular and exophytic mass originating from the liver, which caused gastric outlet obstruction. The mass was resected with a 10mm safety margin. The histopathology report of the mass returned as focal nodular hyperplasia.DISCUSSIONGastric outlet obstruction is a clinical syndrome characterized by abdominal pain, nausea, and postprandial vomiting. This clinical condition frequently develops as a result of peptic ulcer disease, pyloric stenosis, and obstruction of pylorus by foreign bodies including phytobezoars, congenital duodenal webs, malignant disorders, and various lesions externally compressing the stomach. Gastric outlet obstruction due to hepatic lesions is extremely rare; few cases have been reported.CONCLUSIONThis is the first reported case of gastric outlet obstruction that developed due to focal nodular hyperplasia of the liver
Phytocontact dermatitis due to Ranunculus arvensis mimicking burn injury: report of three cases and literature review
Ranunculus arvensis (corn buttercup) is a plant species of the genus Ranunculus that is frequently used in the Far East to treat rheumatic diseases and several dermatological disorders. In Turkey, the plant is seen in the eastern and southeastern Anatolian highlands, which are underdeveloped areas of the country. Herein, we report three patients who used Ranunculus arvensis for the treatment of arthralgia and osteoarthritis. A distinctive phytodermatitis developed on the right thumb in one patient (48-year-old male), on the anterior aspect of both knees in another patient (70-year-old female) and all around both knees in a third (59-year-old female). The patients were treated with topical antibiotics and daily wound dressing, and none of them experienced any complications. Ranunculus arvensis was confirmed as the cause of the phytodermatitis in the three cases. Poultices of plants applied to the skin demonstrate beneficial effects on many dermatological and rheumatic diseases; however, they have several adverse effects that should not be ignored. In this study, we also present a review of 25 cases reported in the literature
The Effect of Antivascular Endothelial Growth Factor on the Development of Adhesion Formation in Laparotomized Rats: Experimental Study
Aims. This study determined the effects of a single dose of bevacizumab, an antiangiogenic recombinant monoclonal antibody that specifically targets vascular endothelial growth factor (VEGF), on adhesion formation in the rat cecal abrasion model.
Methodology. Thirty female Wistar albino rats (200–224 g) were divided into three groups. All rats underwent laparotomy at which time cecal wall abrasion and abdominal wall injuries were induced. Group I (control) underwent only the abrasion procedure; Groups II and III received saline or bevacizumab intraperitoneally, respectively, following the abrasion. The rats were killed on postoperative day 7, and the severity of adhesions was evaluated, together with histopathological fibrosis parameters and immunohistochemical staining to identify the VEGF receptor. Results. The mean adhesion severity score in Groups I–III was 2.5 ± 0.52, 2.4 ± 0.69, and 0.7 ± 0.82, respectively; the score in Group III was significantly lower than that in Groups I (P < 0.001) and II (P < 0.001). In the histopathological evaluation, the mean fibrosis score in Group III was significantly lower that the scores in Groups I (P < 0.001) and II (P < 0.001). VEGF staining of the adhesion areas in Group III was significantly lower than that in Groups I (P < 0.001) and II (P < 0.001). Conclusion. Bevacizumab decreases adhesion formation following laparotomy in rats by blocking VEGF receptor occupancy
Current Barriers to Clinical Liver Xenotransplantation
Preclinical trials of pig-to-nonhuman primate liver xenotransplantation have recently achieved longer survival times. However, life-threatening thrombocytopenia and coagulation dysregulation continue to limit preclinical liver xenograft survival times to less than one month despite various genetic modifications in pigs and intensive pharmacological support. Transfusion of human coagulation factors and complex immunosuppressive regimens have resulted in substantial improvements in recipient survival. The fundamental biological mechanisms of thrombocytopenia and coagulation dysregulation remain incompletely understood. Current studies demonstrate that porcine von Willebrand Factor binds more tightly to human platelet GPIb receptors due to increased O-linked glycosylation, resulting in increased human platelet activation. Porcine liver sinusoidal endothelial cells and Kupffer cells phagocytose human platelets in an asialoglycoprotein receptor 1-dependent and CD40/CD154-dependent manner, respectively. Porcine Kupffer cells phagocytose human platelets via a species-incompatible SIRPα/CD47 axis. Key drivers of coagulation dysregulation include constitutive activation of the extrinsic clotting cascade due to failure of porcine tissue factor pathway inhibitor to repress recipient tissue factor. Additionally, porcine thrombomodulin fails to activate human protein C when bound by human thrombin, leading to a hypercoagulable state. Combined genetic modification of these key genes may mitigate liver xenotransplantation-induced thrombocytopenia and coagulation dysregulation, leading to greater recipient survival in pig-to-nonhuman primate liver xenotransplantation and, potentially, the first pig-to-human clinical trial
