Die direkte perkutane radiologische Jejunostomie (PRJ) und Duodenostomie: eine retrospektive Auswertung
2005
Purpose: To present our experience with direct percutaneous radiologic duodenostomy and jejunostomy (PRJ) for alimentation. Materials and Methods: A retrospective study identified 24 patients who had undergone percutaneous jejunostomy or duodenostomy guided by CT and fluoroscopy over a period of 9 years. Whenever possible, the jejunum was inflated with a 5 French diagnostic catheter and jejunopexy was performed using Cope anchors (T-fasteners). A 12 to 14 French locking pigtail drain was inserted for alimentation. In 8 patients, percutaneous direct jejunostomy was performed using only fluoroscopy. In 9 patients, both CT and fluoroscopy were used to guide the jejunostomy. In all 7 patients w…
Is preoperative radiographic localization of islet cell tumors in patients with insulinoma necessary?
1993
Preoperative localization tests [sonography, computed tomography, angiography, percutaneous transhepatic portal venous sampling for insulin radioimmunoassay (PTP)] have a sensitivity of 60% to 90% in cases of organic hyperinsulinism. In all publications, however, the sensitivity of intraoperative localization, 75% to 100%, is distinctly higher. With the exception of PTP, all tumors that can be identified by preoperative localization can also be detected using palpation or intraoperative sonography. Preoperative localization diagnosis is therefore not absolutely necessary prior to primary operation in the case of organic hyperinsulinism. It is requested by many surgeons because: (1) only a f…
C-Reactive Protein Is Elevated Only in High Creatine Kinase Responders to Muscle Damaging Exercise.
2019
The purpose of this study was to investigate if exertional rhabdomyolysis induced by an acute bout of plyometric exercise in untrained individuals was associated with histological characteristics of skeletal muscle, creatine kinase (CK) polymorphism or secondary damage. Twenty-six healthy male untrained individuals completed a bout of plyometric exercise (10 sets of 10 maximal squat jumps, with each standardized to achieve at least 95% of individual maximal jump height). Blood samples were taken, and perceived pain was scored immediately before the exercise intervention and 6 h, 1, 2, and 3 days post-intervention. Muscle biopsies were collected 9 or 4 days before (baseline) and 3 days after…
Kinematics of shoulder abduction in the scapular plane
1995
In this paper the kinematics of arm abduction in the scapular plane of 38 healthy experimental subjects is reported. The ratio of the glenohumoral and the scapulothoracic components of the motion were determined and the influence of the abduction speed and of the external load on it were investigated. The investigation of the effect of abduction speed involved all 38 subjects. Each of them performed one slow and one fast abduction. Statistical analysis showed that there were large differences between individuals, but that for any one individual the abduction process is essentially reproducible. For the one individual there is a strong, linear relationship between glenohumeral and scapulotho…
Biomechanical and histological evaluation of abdominal wall compliance with intraperitoneal onlay mesh implants in rabbits: A comparison of six diffe…
2012
Abstract Background An ideal prosthetic mesh for incisional hernia repair should mimic the anisotropic compliance of the abdominal wall, and at lower loads should exhibit higher distensibility without impairment of safety at higher loads. This study evaluated the biomechanical properties of six meshes in a rabbit model. Methods New Zealand white rabbits were used for this study. Two meshes of the same brand (Ethicon Physiomesh™, Bard Composix ® L/P, Gore Dualmesh ® , Bard Sepramesh ® , Ethicon Proceed ® or Parietex™ Composite) were implanted into each animal for assessment of intra-abdominal hernia repair, with a total of ten meshes per group. Twelve weeks after implantation, the abdominal …
Non-invasive ventilation in postoperative patients: A systematic review
2010
Background: Postoperative pulmonary complications, generally defined as any pulmonary abnormality occurring in the postoperative period, are still a significant issue in clinical practice increasing hospital length of stay, morbidity and mortality. Non-invasive ventilation (NIV), primarily applied in cardiogenic pulmonary edema, decompensated COPD and hypoxemic pulmonary failure, is nowadays also used in perioperative settings. Objective: Investigate the application and results of preventive and therapeutic NIV in postsurgical patients. Design: A systematic review. Data sources: Medical literature databases were searched for articles about "clinical trials," "randomized controlled trials" a…
Treatment of congenital abdominal wall defects —a 25-year review of 132 patients
2013
The outcome data of 132 patients treated at the Department of Pediatric Surgery in Mainz during the last 25 years were reviewed. Prenatal diagnosis of abdominal wall defects (AWDs) and associated malformations led to increasing selection of the patient population. The aim of primary closure of the abdominal wall can be achieved more frequently in gastroschisis (GS) than omphalocele (OC), while the postoperative course is more complicated and of longer duration in GS. Delayed or secondary closure extended the hospitalization period but had no negative effects on the outcome. Reoperations or planned secondary operations were performed in 23 patients with GS and 14 with OC. Early mortality was…
Die Perforation bei Morbus Crohn als Komplikation in der Schwangerschaft
1991
The manifestation of Crohn's disease with perforation in pregnancy has been described in one case only. In our case, a 25-year-old woman in the 28th week of pregnancy was admitted to our hospital with signs of an acute abdomen. Due to deterioration of the maternal and foetal situation, the child was delivered by a Caesarean section. Subsequently, exploration of the abdomen showed an ileum perforation with diffuse fibrinous peritonitis. In this case, the definitive diagnosis could not be made prior to laparotomy. The aim of surgical therapy in such cases should be the limited resection with end to end anastomosis. In diffuse peritonitis, discontinuous resection and secondary reconstruction a…
Técnicas reconstructivas tras amputación abdominoperineal extraelevadora del recto o exenteración pélvica: mallas, plastias y colgajos
2014
Perineal wound complications after abdomino-perineal rectal resection are frequent and clinically relevant for their impact on the length of hospitalization, costs, patients' quality of life and oncologic results. With the diffusion of the preoperative radiotherapy and the gradual shift to the extra-elevator technique, the perineal morbidity rate has increased. Many series describing different techniques of primary closure of the perineal defect have been published, but high-quality clinical studies, indicating which is the best option, are missing. A biologic mesh, associated if possible to an omentoplasty, seems to be sufficient to close the perineal defect after extra-elevator abdomino-p…
Surgical treatment of chronic thromboembolic pulmonary hypertension
1999
Background: Chronic thromboembolic pulmonary artery obstruction from unresolved pulmonary emboli is characterized by persistent elevation of pulmonary vascular resistance and progressive right heart dysfunction and failure. The diagnosis of chronic thromboembolic pulmonary hypertension is difficult and often missed. Medical therapy is ineffective in these patients. The prognosis is poor and depends on the degree of pulmonary hypertension. Pulmonary thromboendarterectomy has proven to be an effective and potentially curative surgical therapy for this clinical entity although less than 1000 cases have been reported in the surgical literature. Methods: The current principles of diagnosis, pati…
