RESUMEN
BACKGROUND: Balloon sinuplasty (BSP) is a catheter-based technique to dilate sinus ostia and drainage pathways to create ventilation and drainage. The aim of this study was to evaluate the feasibility of BSP in routine treatment of patients suffering from chronic rhinosinusitis (CRS). METHODOLOGY: Patients with CRS refractory to medical therapy who had been scheduled for endoscopic sinus surgery between 2009 and 2011 were included in this study. RESULTS: Forty-five consecutive patients were included in this study, in whom 112 sinuses were approached by BSP. Of the 112 sinuses, 68 (60%) were planned as a "Balloon-Only" procedure and 44 (40%) were planned as a "Hybrid" procedure. Of the 68 sinuses in the "Balloon-Only" group, in 44 sinuses BSP failed, equating to a failure rate of 65%. Forty-four sinuses were planned for "Hybrid" procedures. In 29 of these sinuses BSP failed, giving a failure rate of 66%. CONCLUSION: According to literature, BSP can be a useful adjunct technique to standard FESS. In our experience, however, a failure rate of 65% for "Balloon-Only" and of 66% for "Hybrid" procedures occurred, which was regarded as unacceptable by the study group. Therefore, the study initially scheduled for 200 consecutive patients, was abandoned.

BACKGROUND: Risk factors for postoperative haemorrhage after tonsillectomy are discussed controversy. In the past years surgical techniques were considered a determining factor for post-tonsillectomy bleedings in several studies. MATERIAL AND METHODS: In a prospective, multicentre study 9,405 patients--of whom 4,437 underwent tonsillectomy and were focused in this article--were evaluated during study -period of 9 months (1st October 2009 till 30th June 2010). Postoperative haemorrhage was defined as any bleeding episode after extubation and classified according to a 7 grade scheme. RESULTS: Postoperative haemorrhage occurred in 14.4% (637/4,437) patients with 4.6% (204/4,437) requiring a return to theatre and 9.8% (433/4,437) experiencing minor bleedings. Bipolar techniques (with or without cold steel dissection) showed a haemorrhage risk of 16.8% (62/370). Severe bleedings occurred significantly more often with the use of bipolar techniques (8% compared to 4.6% severe bleedings for all operation techniques, p=0.003). In addition, Coblation® technique had a higher postoperative haemorrhage rate (23.5%, 12/51). However, minor bleedings occurred in the majority of patients operated with Coblation® technique (20% compared to 9.8% minor bleedings for all operation techniques, p<0.017). CONCLUSION: Following the strict definition of postoperative haemorrhage, we found higher postoperative haemorrhage rates for bipolar techniques and Coblation® technique. The proportion of severe bleedings is higher for bipolar methods, whereas the proportion of minor bleedings is higher for Coblation® technique.

BACKGROUND: Postoperative haemorrhage is the most common and serious complication of tonsil and adenoid surgery. Definitions, frequency and risk factors of postoperative bleedings are however, controversially discussed in the literature. PATIENTS AND METHODS: In a prospective multicenter cohort study all tonsillectomies (TE), adenotonsillectomies (TE + AE), tonsillotomies (TO), adenotonsillotomies (TO + AE) and adenoidectomies (AE) performed within 9 months from October 1st, 2009 - June 30th, 2010 were collected and evaluated. Postoperative haemorrhage was defined as any bleeding after extubation and was classified into 7 grades A1, A2, B1, B2, C, D and E depending on the therapy needed and the postoperative day. RESULTS: Data from 9 405 patients of 32 ENT-departments in Austria were analysed. Overall postoperative haemorrhage rate for TE was 16.0%, for TE + AE 11.8%, for TO±AE 2.3% and for AE 0.8%. Surgical revision was necessary in almost one third of patients with a postoperative bleeding event (TE 5.3%, TE + AE 4.1%, TO 0.8% und AE 0.3%). Multiple haemorrhage occurred in every 5th patient, who experienced postoperative bleeding (1.7% of all patients). The frequency of haemorrhage depended on the type of surgery and the age of the individual. Severe bleedings requiring surgical revision were more frequent in children between 6 and 15 years and AE. 9 patients (1.2% of all patients with haemorrhage) experienced a dramatic haemorrhage (grade D), with the need of blood transfusions and difficult surgical control. No deaths occurred during the study period. CONCLUSIONS: Due to a new classification postoperative bleeding episodes could be precisely defined and postoperative risk factors were quantified. Considering all postoperative bleedings, including minor and anamnestic ones, the haemorrhage rate over all types of surgeries was 7.9% (2.7% of all patients required a surgical revision). Tonsillectomy (with or without adenoidectomy) carries the highest statistical risk of postoperative bleeding, with 4.9% of all patients requiring surgical intervention. Patients who experience one - albeit minimal - postoperative haemorrhage, have a 5 times higher risk for further bleeding requiring surgical control, and should therefore be carefully monitored.

BACKGROUND: Tonsillectomy (TE), tonsillotomy (TO) and adenoidectomy (AE) are surgeries performed routinely by otorhinolaryngologists. There were 5 cases of fatal postoperative bleeding in Austria during the years 2006 and 2007, all in children under 6 years of age. The intensive discussion following these sad events resulted in a Consensus Paper of the Austrian Society of ORL, H&NS with the Austrian Society of Pediatrics with modified recommendations towards indications and surgical techniques in different age groups; in addition, the prospective study presented here was initiated. In Austria for the first time a full census could be performed assessing all TE, TO and AE with standardized definitions. MATERIAL AND METHODS: Within the study period of 9 months' from October 1, 2009, to June 30, 2010, data on patients' characteristics, indication for surgery, surgical technique and postoperative haemorrhage were prospectively collected. Postoperative haemorrhage was defined as any bleeding after extubation regardless of whether or not a surgical intervention was required. Postoperative bleeding events were categorised into 7 grades depending on severity. RESULTS: More than one million data of 9,405 patients from 32 ENT-departments in Austria were collected and analysed. One third were children younger than 6 years (n=3,474; 37%) and one third were adults (n=3,507, 37%). A TE ±AE was performed in 48.8% (n=4,594), an AE in 37.1% (n=3,492) and a TO in 14.0% (n=1, 319). For the indication "recurrent tonsillitis and tonsilar hypertrophy" 70% of children had a TO but 95% of adults had a TE (p<0.001). Adults with OSAS had a TE whereas in children aged younger than 6 with the same indication a TO was preferably performed in 90% (p<0.001). For TO the Colorado-needle and the Coblation technique were most commonly used. The Adenotome by La Force and the Adenoid curette by Beckmann, with or without endoscopic control, were most frequently used for AE. CONCLUSIONS: For the first time a prospective full survey could be performed in one country assessing all tonsil and adenoid surgeries along standardized criteria. The study gives an overview about the types of surgery, the indications, the operation techniques and the frequency of postoperative haemorrhage. The latter, because of its clinical importance, is dealt with and described in detail in the second part of this publication.

INTRODUCTION: Arnold Chiari Malformation Type II can be associated with basilar invagination through an elongated retroflexed odontoid process (dens axis). Traditionally, decompression surgery has been performed transorally under microscopic vision or via transcutaneous latero-cervical/posterior approaches. Endoscopic approaches were introduced a few years ago. CASE REPORT: We report of an eleven-year-old girl with Arnold Chiari Malformation Type II who had undergone surgery eight years ago for posterior cranial fossa decompression at the department of neurosurgery. At that time, an external transcutaneous median approach was performed to resect the posterior arch of the atlas. The patient now presented with the initial symptoms of brainstem compression as a result of an elongated retroflexed odontoid process and craniocervical instability. SURGICAL TECHNIQUE: An endoscopic transoral/transnasal approach was chosen for the resection of the dens. CONCLUSION: Endoscopic surgery was successful and the complete resection of the dens was achieved without any complications. In a second intervention, orthopaedic surgeons performed cranio-cervical arthrodesis.

The biodiversity of fungi isolated from the nasal mucus of patients suffering from chronic rhinosinusitis and from healthy persons was monitored over 28 months. Mucus samples were obtained by flushing the noses of patients with saline or by endoscopic sinus surgery. Fungi from mucus were cultivated on agar plates. Identification was performed microscopically and by polymerase chain reaction with subsequent sequencing of the ribosomal internal transcribed spacer region. Altogether, 619 strains of fungi were cultivated from 233 subjects. Eighty-one species were identified, with a maximum of nine different species per person. The most prevalent isolates belonged to the genera Penicillium, Aspergillus, Cladosporium, Alternaria and Aureobasidium. Whereas Aspergillus and Penicillium spp. occurred in more or less the same numbers throughout the year, Cladosporium spp., Alternaria spp. and Aureobasidium pullulans showed a significantly higher occurrence during late summer and early autumn.

BACKGROUND: The optimal management of patients with reflux-associated laryngitis is unclear. We performed a placebo-controlled crossover trial in patients with proven reflux disease and associated laryngitis to determine the effect of pantoprazole and to gain information on the natural course of the disease. METHODS: Sixty-two consecutive non-smoking patients with hoarseness and proven laryngitis were examined. Scores with respect to the larynx and for subjective complaints were determined and 24-h pH-metry to assess acid reflux in the lower oesophagus and pharynx was performed. Patients with pathologic reflux were given the chance to enter a double-blinded randomized crossover trial with pantoprazole 40 mg b.i.d. and placebo for a duration of 3 months each, separated by a 2-week washout period. RESULTS: Twenty-four of 62 patients showed pathological reflux; 21 patients were included in the study and 14 concluded all parts of the study. Both pantoprazole and placebo resulted in a marked improvement in laryngitis scores (decrease of 8.0 +/- 1.4 versus 5.6 +/- 2.6; no significant difference between the 2 treatments) and symptoms after the first 3 months (decrease of oesophageal symptom score of 2.2 +/- 1.4 versus 5.4 +/- 2.8; decrease of laryngeal scores of 8.3 +/- 3.6 versus 10.3 +/- 3.9; also no significant difference between the 2 treatments). A second pH-metry 2 weeks thereafter proved the persistence of reflux in most of these patients. Switching to pantoprazole led to a further improvement of scores. In the group switched to placebo there was recurrence only in a minority of patients. CONCLUSIONS: The self-limited nature of reflux-associated laryngitis in non-smokers is largely underestimated. Laryngitis improves despite the persistence of reflux. Pantoprazole may be helpful especially in relieving acute symptoms, but the advantage of long-term treatment over placebo has been greatly overestimated.

UNLABELLED: The purpose of this study was to investigate whether patients operated for skull base-infiltrating malignant tumors of the nasal cavity and/or the paranasal sinuses benefit from an additional Gamma knife radiosurgery. CASE SERIES: eight consecutive patients, (male: female ratio = 1:1, mean age = 52 years, range 34 to 79 years) presented with 2 cyclindric cell carcinomas, 2 adenocarcinomas, 2 malignant neuroblastomas, 1 squamous cell carcinoma, 1 amelanotic melanoma. Tumor stages (UICC) were: 1 T1, 3 T2, 3 T3, 1 T4, all N0, all M0. All patients were primarily treated surgically and 4 weeks later received additional stereotactic radiosurgery. Follow-up was based on computerized tomography (CT), magnetic resonance imaging (MRI), endoscopy, and biopsy. The course of disease was compared to tumor courses with surgery but without radiosurgery reported in literature. Four times endoscopic endonasal surgery (EES), once EES in combination with fluorescein technique, once EES plus external approach of frontal sinus, once lateral rhinotomy was performed. All 8 cases underwent radiosurgery (Leksell gamma knife) 4 weeks after surgery. Thirty six months after radiosurgery 6 patients were alive (4 patients without evidence of disease, 1 patient with pulmonary metastasis but without local recurrence, 1 patient with regional metastasis but no local recurrence), 1 patient died 11 months after treatment due to disease, 1 patient died due to a second malignancy. No negative or adverse effects due to radiosurgery were observed. The combination of microsurgery with Leksell Gamma knife radiosurgery appears to be an encouraging therapeutic option. To date no adverse effects have been observed in the presented cases.

PURPOSE: Gap junctions composed of connexin proteins have an essential role in intercellular communication and differentiation. Dysregulation of connexin expression is believed to have a role in carcinogenesis. The human prostate has been reported to express connexin 32 and 43. However, the expression pattern in prostate cancer is controversial, while to our knowledge connexin expression has not been reported in benign prostatic hyperplasia (BPH). To understand the potential involvement in prostate disease connexin 32 and 43 expression was evaluated in a series of normal prostate, BPH and prostate cancer specimens that were surgically removed due to bladder outlet obstruction. MATERIALS AND METHODS: Frozen sections of 23 normal, 43 BPH and 40 cancer involved prostates were evaluated for the presence, staining intensity and pattern of connexin 32 and 43 by immunocytochemical testing. RESULTS: In all specimens examined connexin 43 stain was punctate along the borders of the basal epithelial cells, whereas connexin 32 immunolocalized to luminal epithelial cells. In normal prostate connexin 43 and 32 were present in 87% and 65% of specimens, respectively, at low to moderate stain intensity. Importantly none of the normal samples were negative foreach connexin. In BPH specimens there was a marked increase in the incidence and intensity of connexin 43 and 32 immunostaining within epithelial cells. In addition, 23% of BPH samples showed strong connexin 43 expression in stromal cells. In contrast, connexin was decreased in prostate cancer specimens, of which 65% and 38% were negative for connexin 43 and 32, respectively, and 28% were negative for each type. In poorly differentiated tumors connexin 43 and 32 were present in only 10% and 40% of tumors, respectively, at low immunostaining intensity. CONCLUSIONS: In normal human prostate basal cells communicate via connexin 43 gap junctions, whereas luminal cells communicate via connexin 32 gap junctions. In BPH gap junctional intercellular communication is increased in epithelial and stromal cells, which may have a role in BPH pathogenesis. In prostate cancer gap junctional intercellular communication is decreased, is as indicated by decreased expression of connexin 43 and 32 with severe loss in poorly differentiated prostate cancer. These alterations in connexin expression may have a role in dedifferentiation and tumor progression.

A subglottic tophaceous deposition of urate crystals is a rare finding. We report on a case of a male Caucasian who had a moderate dysphonia without any further laryngeal symptoms. The laryngoscopy revealed a hemispheric lesion on the left subglottic region. An excision biopsy was performed, and the histopathological examination of the dissected specimen showed a tophus. Diagnostic and therapeutic strategies are discussed.

OBJECTIVES: In tumors of the upper aerodigestive tract a dose-response relationship between tumor stage and its prognosis raises the chance of a reduction in the diagnostic delay. The interval between the first symptom and the start of tumor-specific therapy and the influencing factors is not well known. The goals of this study were to investigate the diagnostic delay and the influencing factors and to predict the factors that prolong the diagnostic process. STUDY DESIGN: Prospective, nonrandomized study. METHODS: The intervals between first symptom and first consultation of a physician (patient delay) and between first consultation and first tumor-specific therapy (doctor delay) were investigated. Predictors for increased patient or doctor delay were evaluated, and a multiple logistic regression model for increased doctor delay was developed. RESULTS: The total diagnostic delay (sum of patient and doctor delays) was 3 to 4 months. A multifactorial model for the ratio of odds revealed that for women and glottic cancers (1.73) the chance was twice as high for a doctor delay greater than 30 days, whereas subjects with an increased patient delay (>30 d) had reduced odds of being delayed by the physician. CONCLUSIONS: The higher chance of extended doctor delay for glottic tumors compared with supraglottic tumors should be reflected in differential therapeutic strategies. Even unspecific lesions of the vocal folds should be followed up at the end of the therapy, at least. Therapies of glottic lesions without final control have the chance of resulting in delays in treatment. Women, especially, should be included in a follow-up examination. On the other hand, patients with increased patient delay have lower odds of longer doctor delay, which may be the result of tumor growth and, consequently, easier diagnosis.

OBJECTIVE: We evaluated the impact of delayed scans on the conspicuity of squamous cell carcinoma in helical CT of the head and neck. SUBJECTS AND METHODS: Twenty-seven patients with biopsy-proven squamous cell carcinoma of the head and neck underwent dual-phase helical CT examinations using 100 mL of nonionic contrast material. In all patients, the early phase started 30 sec after the commencement of injection. The patients were assigned to one of two groups in which the delayed phase started either 180 sec (group A, n = 13) or 300 sec (group B, n = 14) after the start of injection. The overall image quality, including vascular opacification and the quality of lesion conspicuity, was determined according to a three-point scoring system. RESULTS: Overall image quality scored better on the early scans (score, 1.4 +/- 0.5) than on the late scans with a 180-sec (score, 1.6 +/- 0.6; p = 0.03) or a 300-sec delay (score, 2.4 +/- 0.5; p = 0.002). Tumor conspicuity scored better on scans with a 180-sec delay (score, 1.4 +/- 0.5) than on the scans with a 30-sec delay (score, 2.3 +/- 0.7; p = 0.02) or the scans with a 300-sec delay (score, 2.3 +/- 0.7; p = 0.03). In eight (62%) of 13 patients in group A and in six (43%) of 14 patients in group B, the tumor was better delineated on the late scans than on the early scans. CONCLUSION: Although early scans provide optimal vascular enhancement and are therefore necessary for helical CT studies of the head and neck, additional delayed scans may improve lesion detection in patients with squamous cell carcinoma of the head and neck.

The following double-blind, placebo-controlled, multicenter study investigated the influence of a bacterial immunostimulant (Symbioflor 1, cells and autolysate of human Enterococcus faecalis) on the occurrence of relapses in patients with chronic recurrent bronchitis (n = 136; placebo n = 66, verum n = 70) in a 6 months treatment period and a follow-up period of 8 months, compared to placebo. Under verum 39 incidents of relapses were recorded, which was about 60% the number observed among the patients treated with placebo (66 incidents). The verum preparation exhibited superior clinical efficacy compared to placebo (p = 0.001) in the Kaplan-Meier test. This better clinical efficiency of the test preparation was particularly observed during the treatment period, with 12 vs. 27 relapses (p = 0.013), but less during the follow-up observation period, with 27 vs. 39 relapses (p = 0.127). In addition, the time span until occurrence of the first relapse was clearly longer under verum (699 days) than under placebo (334 days) and after the end of the observation period 91% of patients under verum experienced only one relapse compared to 62% in the placebo group (p = 0.01). Severity of relapses under verum was also reduced significantly (chi 2; p = 0.001. Only 4 patients under verum required antibiotic therapy compared to 13 patients under placebo. Verum was equally well tolerated as placebo, with no serious side effects in either group. No changes in laboratory tests--haematology and clinical chemistry--were observed. It can be concluded, that previously demonstrated immunomodifying effects of the test preparation have clinical relevance for the treatment of chronic recurrent bronchitis because not only the number but also the severity of acute relapses could be clearly reduced. This is discussed in view of the current literature.

Photoglottography (PGG) is an established technique for depicting the vibratory patterns of the vocal folds. The present study investigates the correlation between the glottal area and the corresponding PGG signal. Six normal (five male, one female) subjects who did not use their voices professionally were investigated during constantly sustained phonation at spontaneous pitches. Laryngostroboscopy was performed in combination with PGG. The simultaneously recorded laryngostroboscopic images and PGG signals were directly digitized and stored on a computer. The correlation between the glottal area and the corresponding PGG amplitudes across each vibratory cycle of the vocal folds was calculated and they were found to be highly and positively correlated (r = 0.973, p < 0.001). The PGG signal reflects changes in the glottal area during the vibration cycle of the vocal folds. The proposed simultaneous laryngostroboscopic and PGG technique has proved to be useful for facilitating the interpretation of changes in glottal area.

Nasality is a disorder due to nasal resonance, which may be induced by a variety of etiologies. Transitional hypernasality is frequently seen in children after adenoidectomy. The alleged post-surgical hypernasality in the case presented was shown to be related to the late detection of an astrocytoma of the cerebellum and the brain stem in a 6-year-old boy. This case was characterized by increased hypernasality which failed speech therapy. A developing one-sided vocal fold palsy in combination with an ipsilateral soft-palate palsy indicated further investigation. Computerized tomography (CT) and magnetic resonance imaging (MRI) revealed a brain stem-tumor with a maximum size of 6 cm involving parts of the cerebellum. These findings demonstrated the need for a strict follow-up, even after adenoidectomy, in the presence of hypernasality for identifying concurrent etiologies as well as cases suitable for speech therapy.

A significant decrease in %IgG1 accompanied by an increase in %IgG2 in total serum IgG has been previously reported as a highly sensitive marker for detecting early stages of carcinomas of various localizations. Here we investigated the question as to whether this phenomenon is also observed in sera of patients with squamous cell carcinoma of the head-neck region (SCC-HN), and to evaluate its diagnostic performance in the post-operative monitoring. Using quantitative affinity chromatography, serum concentrations of IgG1, IgG2 and total IgG were determined in 81 patients with different stages of primary and untreated SCC-HN, in 51 SCC-HN patients in post-therapeutical follow up, and in 33 patients with organ matched benign diseases. The data were compared with a total of 174 healthy controls. It was found that (i) 105 SCC-HN patients exhibited a mean value of 56.0 +/- 0.7% IgG1, which likewise differed from healthy controls (63.2 +/- 0.5) and benign diseases (61.5 +/- 1.0) with P < 0.0005, (ii) sensitivities and specificities for discriminating primary malignancies from healthy controls were 70 and 74% respectively, and from benign diseases 65 and 76%, (iii) highest sensitivities and specificities were observed with post-therapeutic cases suffering from tumour recurrence (88% and 75%) or patients with distant metastases (87% and 86%), (iv) apparently tumour-free post-therapeutic patients showed a mean %IgG1 not different from the normal value. The decrease in %IgG1 accompanied by increased %IgG2 is an efficient, sensitive and early marker of SCC-HN, which appears particularly useful for the post-therapeutic monitoring.

The aim of this study was to investigate whether patients with chronic posterior laryngitis and symptoms of gastro-pharyngeal reflux benefit from a six-week therapy with pantoprozole. Twenty-nine out-patients with voice disorders (case history of at least two months) and simultaneous symptoms of gastro-pharyngeal reflux were recruited for this study. At the entry to the study a symptom questionnaire and a video-laryngo/stroboscopy were completed. The symptom questionnaire and the video-laryngo/stroboscopy were repeated after the six weeks of therapy with pantoprazole 40 mg once a day and again six weeks and three months after this follow-up, during which time the patient was without therapy. Hoarseness, globus pharyngeus, sore throat, heartburn, and coughing were the symptoms which showed a significant (p < 0.05) recovery at the follow-ups (mean of hoarseness index: 7.28 to 0.92; mean of globus pharyngeus index: 3.14 to 0.58; mean of heartburn index: 2.86 to 0.5; mean of cough index: 1.72 to 0.25; mean of throat soreness index: 1.72 to 0.15). Laryngoscopy scores of the posterior laryngeal region, the glottic and the supraglottic region showed statistically significant improvement (p < 0.05) after the treatment with pantoprazole. The therapeutic effect exceeded the drug administration until the last follow-up (after three months). The medication was tolerated without side-effects in all patients. A primary (ex juvantibus) therapy with proton pump inhibitors seems to be a therapeutic option for patients with long-lasting chronic inflammation of the larynx not responding to common therapy. In this case a six-week course of treatment has been shown to be sufficient.

BACKGROUND: In the early 1970s, progress in chemical analysis allowed the assessment of low concentration substances in blood and other body fluids. These techniques led to development of hitherto unknown diagnostic facilities which were tested with respect to malignant tumors. In those days SCC-A was considered a promising substance for aiding in diagnosis and observation in patients with SCC. METHODS: This retrospective study investigates the correlation between tumor size and tumor progress and the SCC-A level in a group of 322 patients (male: n = 291, age 24-87 yrs, mean 56 yrs: female: n = 31, age 38-82 yrs, mean 70 yrs). RESULTS: The diagnostic value of SCC-A turned out to be poor. In 78%, SCC-A levels were low and neither correlated with tumor size nor the presence of metastases. In follow-up the situation was even worse: A reliable correlation between SCC-A and the course of disease was found in 5.8% of patients only. CONCLUSION: The SCC-A could neither reliably contribute to diagnosis nor to follow-up of patients with squamous cell carcinomas of the head and neck.

Non-Hodgkin's lymphoma (NHL) is a frequent head and neck malignancy. Squamous cell carcinoma of the tonsil is the second most common head and neck carcinoma. We report a case of a tonsillar carcinoma metastasis in an angioimmunoblastic-transformedlymph node. To our knowledge this is the first description and histopathological documentation of such a case in the literature.

Both methods of reconstruction after gastrectomy lead more or less to an insufficiency of pancreas. Therefore investigations on rats should further clarify which defects are obvious after both operation methods. Wistar rats were divided into 3 groups. In 2 groups a gastrectomy was performed while one was reconstructed according to the method of Roux-Y, the other was treated according to the method of Longmire-Gütgemann. The first group was a sham operated control group. 3 months after this operation pancreatic juice was collected over the time of 6 hours. Volume and protein content were determined as well as a differentiation of the proteins by means of the 2D electrophoresis which separates the molecules according to isoelectric focus and the molecular weight. The results show a significant increase of the volume of pancreatic juice after both operations. Whereas the protein content is also altered the number of proteins is significantly decreased. Especially proteins with an alkaline isoelectric focus are significantly diminished. The molecular weight of the proteins is also changed. Low molecular protein fragments which were not observed in the sham operated group are increased especially in the Roux-Y group. This means that the production of enzymes is changed after both operations. The pH optimum as well as the viability of the protein enzymes is shifted. Since the changes are more pronounced after Roux-Y operation signs of pancreatic insufficiency should be expected more frequently after this operation.
