| 1 | Biliary cystadenoma with mesenchymal stroma:Report of a case and review of the literature显示文摘Biliary cystadenomas are rare, cystic neoplasms of the biliary ductal system that usually occur in middle- aged women. They cannot be safely differentiated from cystadenocarcinomas before operation and should always be considered for resection. Cystadenomas have a strong tendency to recur, particularly following incomplete excision, and a potential of malignant transformation. Therefore, complete resection is the therapy of choice and thorough histopathologic evaluation is imperative. A case of benign biliary cystadenoma with mesenchymal stroma is presented along with a review of the relative literature addressing the clinical presentation, histology, histogenesis, differential diagnosis, imaging features, treatment and prognosis of this interesting and rare entity. | Andreas Manouras Haridimos Markogiannakis Emmanuel Lagoudianakis Vangelogiannis Katergiannakis | 2006 | World Journal of Gastroenterology2006,12,37: | 13 |
| 2 | Acute mechanical bowel obstruction: Clinical presentation, etiology, management and outcome显示文摘AIM: To identify and analyze the clinical presentation, management and outcome of patients with acute mechanical bowel obstruction along with the etiology of obstruction and the incidence and causes of bowel ischemia, necrosis, and perforation. METHODS: This is a prospective observational study of all adult patients admitted with acute mechanical bowel obstruction between 2001 and 2002. RESULTS: Of the 150 consecutive patients included in the study, 114 (76%) presented with small bowel and 36 (24%) with large bowel obstruction. Absence of passage of flatus (90%) and/or feces (80.6%) and abdominal distension (65.3%) were the most common symptoms and physical finding, respectively. Adhesions (64.8%), incarcerated hernias (14.8%), and large bowel cancer (13.4%) were the most frequent causes of obstruction. Eighty-eight patients (58.7%) were treated conservatively and 62 (41.3%) were operated (29 on the first day). Bowel ischemia was found in 21 cases (14%), necrosis in 14 (9.3%), and perforation in 8 (5.3%). Hernias, large bowel cancer, and adhesions were the most frequent causes of bowel ischemia (57.2%, 19.1%, 14.3%), necrosis (42.8%, 21.4%, 21.4%), and perforation (50%, 25%, 25%). A significantly higher risk of strangulation was noticed in incarcerated hernias than all the other obstruction causes. CONCLUSION: Absence of passage of flatus and/or feces and abdominal distension are the most common symptoms and physical finding of patients with acute mechanical bowel obstruction, respectively. Adhesions, hernias, and large bowel cancer are the most commoncauses of obstruction, as well as of bowel ischemia, necrosis, and perforation. Although an important proportion of these patients can be nonoperatively treated, a substantial portion requires immediate operation. Great caution should be taken for the treatment of these patients since the incidence of bowel ischemia, necrosis, and perforation is significantly high. | Haridimos Markogiannakis Evangelos Messaris Dimitrios Dardamanis Nikolaos Pararas Dimitrios Tzertzemelis Panagiotis Giannopoulos Andreas Larentzakis Emmanuel Lagoudianakis Andreas Manouras Ioannis Bramis | 2007 | World Journal of Gastroenterology2007,13,3: | 7 |
| 3 | Transanal polypectomy using single incision laparoscopic instruments显示文摘Transanal excision of rectal polyps with laparoscopic instrumentation and a single incision laparoscopic port is a novel technique that uses technology originally developed for abdominal procedures from the natural orifice of the rectum. Transanal endoscopic microsurgery (TEM) is a well established surgical approach for certain benign or early malignant lesions of the rectum, under specific indications. Our technique is a hybrid technique of transanal surgery, a reasonable method for polyp resection without the need of the sophisticated and expensive instrumentation of TEM which can be applied whenever endoscopic or conventional transanal surgical removal is not feasible. | Dimitrios Dardamanis Dimitrios Theodorou George Theodoropoulos Andreas Larentzakis Maria Natoudi Georgia Doulami Christina Zoumpouli Haridimos Markogiannakis Stylianos Katsaragakis George C Zografos | 2011 | World Journal of Gastrointestinal Surgery2011,3,4: | 6 |
| 4 | Lipoma induced jejunojejunal intussusception显示文摘Intussusception in adults is rare. The clinical picture of intussusception in adults is subtle and the diagnosis is,therefore,elusive. The presence of a structural abnor- mality in the great majority of the adult cases mandates high clinical suspicion. Gastrointestinal lipomas are rare benign tumors and intussusception due to a gastrointes- tinal lipoma constitutes an infrequent clinical entity. The present report describes a case of jejunojejunal intus- susception in an adult with a history of severe episodes of hematochezia and colicky upper abdominal pain. The diagnosis was suspected preoperatively but computed tomography scan could not rule out malignancy. Explor- atory laparotomy revealed jejunojejunal intussusception secondary to a lipoma which was successfully treated with segmental intestinal resection. | Andreas Manouras Emmanuel E Lagoudianakis Dimitrios Dardamanis Dimitrios K Tsekouras Haridimos Markogiannakis Michael Genetzakis Nikolaos Pararas Artemisia Papadima Christos Triantafillou Vagelogiannis Katergiannakis | 2007 | World Journal of Gastroenterology2007,13,26: | 4 |

| 15 | A symptomatic cyst of the ligamentum teres of the liver: A case report显示文摘Cysts of the liver ligaments are extremely rare and cysts of the ligamentum teres of the liver have been sporadically reported in the literature during the last century. The present report describes a case of a symptomatic patient with a cyst of the ligamentum teres of the liver. The patient presented with right upper quadrant pain and indigestion during the last 2 years. Ultrasound and computed tomography scans revealed a water-density mass attached to the anterior abdominal wall, but definite diagnosis could not be reached. The cyst was completely excised during laparotomy. Cysts of the ligamentum teres of the liver, although infrequent, may produce clinical symptoms and require excision. Ultrasound and computed tomography scan preoperatively cannot rule out malignancy, thus exploratory laparotomy and total resection of these lesions are necessary. | Emmanuel E Lagoudianakis Nikolaos Michalopoulos Haridimos Markogiannakis Artemisia Papadima Konstantinos Filis Panagiotis Kekis Vaggelogiannis Katergiannakis Andreas Manouras | 2008 | World Journal of Gastroenterology2008,14,20: | 0 |
| 16 | Subclinical peritonitis due to perforated sigmoid diverticulitis 14 years after heart-lung transplantation显示文摘Acute complicated diverticulitis, particularly with colon perforation, is a rare but serious condition in transplant recipients with high morbidity and mortality. Neither acute diverticulitis nor colon perforation has been reported in young heart-lung grafted patients. A case of subclinical peritonitis due to perforated acute sigmoid diverticulitis 14 years after heart-lung transplantation is reported. A 26-year-old woman, who received heart-lung transplantation 14 years ago, presented with vague abdominal pain. Physical examination was normal. Blood tests revealed leukocytosis. Abdominal X-ray showed air-fluid levels while CT demonstrated peritonitis due to perforated sigmoid diverticulitis. Sigmoidectomy and end-colostomy (Hartmann's procedure) were performed. Histopathology confirmed perforated acute sigmoid diverticulitis. The patient was discharged on the 8th postoperative day after an uneventful postoperative course. This is the first report of acute diverticulitis resulting in colon perforation in a young heart-lung transplanted patient. Clinical presentation, even in peritonitis, may be atypical due to the masking effects of immunosuppression. A high index of suspicion, urgent aggressive diagnostic investigationof even vague abdominal symptoms, adjustment of immunosuppression, broad-spectrum antibiotics, and immediate surgical treatment are critical. Moreover, strategies to reduce the risk of this complication should be implemented. Pretransplantation colon screening, prophylactic pretransplantation sigmoid resection in patients with diverticulosis, and elective surgical intervention in patients with nonoperatively treated acute diverticulitis after transplantation deserve consideration and further studies. | Haridimos Markogiannakis Manousos Konstadoulakis Dimitrios Tzertzemelis Pantelis Antonakis Ilias Gomatos Constantinos Bramis Andreas Manouras | 2008 | World Journal of Gastroenterology2008,14,22: | 0 |
