    ABSTRACT: We present a case of a combination of primary and secondary diaphragmatic hernia in a 63-year male patient. For progressive dyspnea and palpitations caused by a large and symptomatic Morgagni hernia resulting in a right-sided enterothorax, an open tension-free mesh repair was performed. The postoperative course was complicated by a secondary hepatothorax through a spontaneous rupture of the right diaphragm. Primary mesh repair of the Morgagni hernia, however, proved to be sufficient. This recurrent herniation might be a consequence of (1) preexisting atrophy of the right diaphragm caused by disposition and/or long-term diaphragmatic dysfunction due to the large hernia, combined with (2) further thinning out of the diaphragm by intraoperative hernia sac resection, and (3) postoperative increase of intra-abdominal pressure.

    ABSTRACT: Background: Physical examination of patients with undifferentiated abdominal pain (UAP) in the emergency room traditionally calls for digital rectal examination (DRE). Without a DRE, many textbooks deem a clinical examination incomplete. On the other hand, patients as well as physicians often feel uncomfortable with this breach of privacy involving a DRE. Especially emergency rooms do not offer an atmosphere where a relationship with the necessary mutual trust can be built up. In this light, the objective of this analysis is to assess the evidence for DRE via a systematic search of the relevant literature. Methods and Results: A systematic search in Pubmed, Medline coupled with manual research laid the basis for the evaluation of relevant publications from January 1990 to March 2010. Keywords for the search were: "digital rectal examination" in combination with "acute abdominal pain", "acute abdomen" or "appendicitis". From the raw data of relevant publications, we extracted results into contingency tables and completed missing data. Above all parameters, we determined the likelihood ratios (LR) with corresponding 95 % confidence intervals to assess test quality. Opinions in the evaluated literature and many national and international textbooks diverge significantly on the necessity of DRE. Six studies question the significance of DRE when evaluating patients with undifferentiated abdominal pain and appendicitis, respectively. Out of these studies, five are prospective and one is retrospective. Overall, the diagnostic test quality of DRE was low in all studies with LR + in the range from 0.78 to 1.61 and LR -  from 0.91 to 1.29, respectively. No diagnostic relevance for DRE in combination with acute abdominal pain was found in these studies. Furthermore, in none of the reviewed cases did DRE have a relevant impact on management. Conclusion: The recommendation of generally applying DRE in the emergency room needs to be questioned critically. No evidence for the necessity and significance was found in the reviewed literature. Independently, these findings do not touch on the unequivocal indication of the DRE as a tool for assessing other specific conditions as well as screening for prostate or rectal cancer.

    ABSTRACT: Tumours of the female genital tract are often diagnosed at an advanced stage or re-lapse after initial curative therapy. Ovarian cancer is in particular associated with peritoneal carcinomatosis or local tumour progression entailing different intestinal complications. Based on our own results and a systemic PubMed search, different intestinal complications in non-curable tumours of the female genital tract were defined and different surgical and non-surgical therapeutic options were analysed. Stenosis of the small bowel is often caused by direct infiltration of the tumour. Peritoneal carcinomatosis or postoperative abdominal adhesions may lead to an acute or even more often chronic recurrent obstruction. The rectum or sigmoid colon is in particular affected by stenosis caused by tumour masses within the pelvis, occurring fistulas or direct tumour infiltration which may lead to bleeding complications or a large bowel obstruction. Radiation-induced abdominal adhesions or stenosis of the small bowel as well as radiation-induced chronic proctocolitis are further common abdominal complications. Special attention with regard to a well balanced indication towards surgical, oncological or conservative management must be given in the palliative setting of the genital tract. In particular the dictum of "primum nihil nocere" has to be followed in consideration of the patient's declared intention, the patient's prognosis, general condition, psychological strain as well as the expected complications.

    ABSTRACT: To evaluate a model used to impart advanced wound closure skills because available models do not meet the necessary requirements to a substantial degree. Seventy-one residents were asked to evaluate a 75-minute-long skills course using cadaveric cattle digits to learn Z-plasty, V-Y-plasty, and oval-shaped rotational flaps. A short film and the course instructor demonstrated each technique first. A Likert rating scale ranging from 1 to 6 was used for questions in the survey given to the residents. There was strong agreement among residents (1.65 ± 1.17 years of experience) that advanced wound closure training courses are necessary (5.73 ± 0.73), which corresponded to the residents' low level of knowledge and self-assessment of practical skills and present experience (2.84 ± 1.01). The course was evaluated with high acceptance, even though it was found to be demanding for the trainees (5.84 ± 0.40). This might also be related to the high rating of the model itself, which was found to be a suitable method for teaching advanced wound closure techniques (5.50 ± 0.71) that was easily comprehensible (5.73 ± 0.53). Skills training courses for young trainees are warranted to impart advanced wound closure techniques. The curriculum using cattle digits presented here is recommended. The authors have indicated no significant interest with commercial supporters.

    ABSTRACT: Pulmonary sclerosing hemangioma (SH) is a rare tumor of the lung predominantly affecting Asian women in their fifth decade of life. SH is thought to evolve from primitive respiratory epithelium and mostly shows benign biological behavior; however, cases of lymph node metastases, local recurrence and multiple lesions have been described. We report the case of a 21-year-old Caucasian male with a history of locally advanced and metastatic rectal carcinoma (UICC IV; pT4, pN1, M1(hep)) that was eventually identified as having hereditary non-polyposis colorectal cancer (HNPCC, Lynch syndrome). After neoadjuvant chemotherapy followed by low anterior resection, adjuvant chemotherapy and metachronous partial hepatectomy, he was admitted for treatment of newly diagnosed bilateral pulmonary metastases. Thoracic computed tomography showed a homogenous, sharply marked nodule in the left lower lobe. We decided in favor of atypical resection followed by systematic lymphadenectomy. Histopathological analysis revealed the diagnosis of SH. Cases have been published with familial adenomatous polyposis (FAP) and simultaneous SH. FAP, Gardner syndrome and Li-Fraumeni syndrome, however, had been ruled out in the present case. To the best of our knowledge, this is the first report describing SH associated with Lynch syndrome.

    ABSTRACT: Bladder drainage (BD) of pancreatic transplants is associated with a unique set of complications. We intended to analyze the incidence, indications, complications and long-term results of enteric conversion procedures (EC). Using a prospective database, 32 EC patients out of 433 simultaneous pancreas-kidney-transplant (SPK) recipients were identified. Graft and patient survival rates were compared with those after primary enteric drainage (ED). The mean SPK-EC interval was 5.0 yr, and the mean patient follow-up was 13.8 yr. Indications for EC were genitourinary symptoms (62.5%), duodenal complications (15.6%), graft pancreatitis (12.5%), pyelonephritis (6.3%), and metabolic acidosis (3.1%). All patients reported significant long-term resolution of symptoms. Surgical complications, reoperations, early graft loss, and 30-d mortality occurred in 31.3%, 25.0%, 6.3%, and 3.1% of cases, respectively. Pancreatic graft and patient survival rates at 1, 5, and 10 yr after SPK were comparable between EC patients and ED patients at the same institution. For the treatment of symptoms associated with BD, EC results in excellent long-term graft function and significant resolution of symptoms even years after SPK. Postoperative morbidity after EC including early reoperation and graft loss, however, has to be considered.

    ABSTRACT: Clinical algorithms contribute to the problem- and priority-orientated management of patients and their disease in healthcare. Algorithms are of particular importance in all aspects of emergency medicine where the fast completion of a complex problem according to a hierarchy is required. The advantages and success of this priority- and problem-orientated concept led to its expansion to other subspecialties in medicine in recent years. However, in spite of algorithms being created based on defined norms, they are frequently violated in the literature, which renders the algorithm useless in a particular case. The present debate addresses these issues and provides the formal criteria and their necessary modification for creating sufficient clinical algorithms. In this context, we also clarify the misunderstandings between step-by-step schemes, decision trees, and algorithms, which are often used synonymously, and discuss their implications in clinical medicine and quality management. A clinical algorithm can easily be created with the present derivation of the algorithm by its formal mathematical function using the corresponding norms describing specific symbols for a single criterion. Some symbol modifications as well as the usage of checklists to focus on the major criteria led to a rigorous reduction of the algorithm length and results in a clearer arrangement for routine clinical use. In clinical medicine, algorithms cannot only provide a fast access for solving complex problems but must also assure a transparent protocol and democratic treatment such that every patient receives the same quality of treatment. Thus, a treatment by chance can be excluded by standardization, which might impact the overall work needed to guide patients though diagnostics and therapy and may ultimately reduce cost. Algorithms are useful not only for quality in healthcare but also for undergraduate and continuous medical education. From a more philosophical point of view, we can raise the question of whether medical pathways and thereby the medical art should be disclosed to the general public by algorithms. Hippocrates form Kos held the view in the so-called Hippocratic Oath that medical art should only be revealed to medical scholars. The present derivation and nomination of the formal requirements may lead to a better understanding of algorithms themselves as well as their development and generation.

    ABSTRACT: Numerous models, of variable quality, exist to impart the complex skills required to perform vascular anastomosis. These models differ with regard to the kinds of materials used, as well as their sizes, the time needed for their preparation, their availability, and the associated costs. The present study describes a bench model that uses formalin-fixed porcine aorta, and its evaluation by young surgical residents during a recent skills course. The aortic segments used were a by-product of slaughtering. They were fixed and stored after harvesting for eventual use. Ten young surgical residents participated, and each performed one end-to-side vascular anastomosis. The evaluation was a questionnaire maintaining anonymity of the participant containing questions addressing particular aspects of the model and the experiences of the trainee, along with their ratings concerning the need for a training course to learn vascular anastomosis techniques. The scoring on the survey was done using a global 6-point rating scale (Likert Scale). In addition, we ranked the present model by reviewing the current literature for models that address vascular anastomosis skills.The trainees who participated were within their first two years of training (1.25 +/- 0.46). A strong agreement in terms of the necessity of training for vascular anastomosis techniques was evident among the participating trainees (5.90 +/- 0.32), who had only few prior manual experiences (total number 1.50 +/- 0.53). The query revealed a strong agreement that porcine aorta is a suitable model that fits the needs for training vascular anastomosis skills (5.70 +/- 0.48). Only a few bench models designed to teach surgical residents vascular anastomosis techniques were available in the literature. The preparatory and financial resources needed to perform anastomosis skills training using porcine aorta are few. The presented bench model appears to be appropriate for learning vascular anastomosis skills, as rated by the surgical trainees themselves.
