Simultaneous laryngopharyngeal pH monitoring (Restech) and conventional esophageal pH monitoring-correlation using a large patient cohort of more than 100 patients with suspected gastroesophageal reflux disease

24-hour esophageal pH-metry is not designed to detect laryngopharyngeal reflux (LPR). The new laryngopharyngeal pH-monitoring system (Restech) may detect LPR better. There is no established correlation between these two techniques as only small case series exist. The aim of this study is to examine the correlation between the two techniques with a large patient cohort. All patients received a complete diagnostic workup for gastroesophageal reflux including symptom evaluation, endoscopy, 24-hour pH-metry, high resolution manometry, and Restech. Consecutive patients with suspected gastroesophageal reflux and disease-related extra-esophageal symptoms were evaluated using 24-hour laryngopharyngeal and concomitant esophageal pH-monitoring. Subsequently, the relationship between the two techniques was evaluated subdividing the different reflux scenarios into four groups. A total of 101 patients from December 2013 to February 2017 were included. All patients presented extra-esophageal symptoms such as cough, hoarseness, asthma symptoms, and globus sensation. Classical reflux symptoms such as heartburn (71%), regurgitation (60%), retrosternal pain (54%), and dysphagia (32%) were also present. Esophageal 24-hour pH-metry was positive in 66 patients (65%) with a mean DeMeester Score of 66.7 [15-292]. Four different reflux scenarios were detected (group A-D): in 39% of patients with abnormal esophageal pH-metry, Restech evaluation was normal (group A, n = 26, mean DeMeester-score = 57.9 [15-255], mean Ryan score = 2.6 [2-8]). In 23% of patients with normal pH-metry (n = 8, group B), Restech evaluation was abnormal (mean DeMeester-score 10.5 [5-13], mean Ryan score 63.5 [27-84]). The remaining groups C and D showed corresponding results. Restech evaluation was positive in 48% of cases in this highly selective patient cohort. As demonstrated by four reflux scenarios, esophageal pH-metry and Restech do not necessarily need to correspond. Especially in patients with borderline abnormal 24-hour pH-metry, Restech may help to support the decision for or against laparoscopic anti-reflux surgery.

Spontaneous omental bleeding in a 20-year old patient with hemophilia A

Spontaneous intraabdominal hemorrhage is a very rare event even in patients with bleeding disorders like hemophilia. Nevertheless this rare case must be considered in patients with coagulopathies presenting with abdominal pain. Prompt radiologic imaging and surgical consultation are of highest priority. Here we report on a 20-year-old patient with moderate hemophilia A, who underwent emergency laparotomy for a spontaneous idiopathic bleeding of the omentum majus. There are few cases in the literature on this sort of event in patients with hemophilia, who mostly suffer from spontaneous joint bleedings. These patients require an intensive, interdisciplinary perioperative care, involving haematologists, surgeons, radiologists and anesthesists. Finally we discuss, whether an optimized, individually adapted treatment with coagulation factors might possibly have prevented this bleeding event in this patient.

[Papillary tumors - therapeutic concepts]

Papillary tumors originate from the various structures of the ampulla of Vater; therefore, these rare tumors represent a heterogeneous group of tumor entities. Intestinal differentiated adenomas are the most common benign lesions, whereas intestinal differentiated papillary carcinomas are the most common malignant tumors. Carcinomas with pancreaticobiliary differentiation have a poorer prognosis. Mesenchymal and neuroendocrine tumors are among the least frequent papillary tumors. Diagnosis is performed by side-view upper endoscopy and biopsy. In cases of suspected malignancy a complete staging with computed tomography (CT) and endoscopic ultrasound scanning is indicated to determine local tumor spread.Adenomas are removed by endoscopic snare papillectomy whereas the therapy of choice for papillary carcinomas is pancreatic head resection with systematic lymphadenectomy. Patients with papillary carcinomas are most likely to benefit from adjuvant therapy, which should be determined in an interdisciplinary consensus conference considering the histological differentiation of the tumor.

[Teamwork in the operating theatre: the German Observational Teamwork Assessment for Surgery (OTAS-D) and its first application in Germany]

BACKGROUND

The quality of surgical teamwork contributes to performance of the operating theatre team, service quality and patient safety in surgery. Observational tools are a feasible and reliable way to capture and evaluate teamwork in the operating theatre (OT). We introduce the German version of the Observational Teamwork Assessment for Surgery (OTAS-D) and present the first observational results from German OTs.

METHODS

Quality of surgical teamwork was assessed with observational teamwork assessment for surgery (OTAS-D). It evaluates five dimensions of OT teamwork: communication, coordination, cooperation/backup behaviour, leadership, and team monitoring/situation awareness. Each dimension is evaluated for each profession (surgical, nursing, and anaesthesia team) as well for each phase of the procedure (pre-, intra-, and post-operative). We observed n = 63 procedures, mainly in abdominal/general and orthopaedic surgery. Additionally, all OT team members scored their individual evaluation of the intra-operative teamwork (standardised 1-item questions).

RESULTS

The OTAS-D evaluations showed meaningful results and differences for the OT professions as well as across the different phases of the procedures. Overall, a medium to good level of the OT teamwork was observed. There were no differences in regard to type of surgery (minimally invasive vs. open) or surgical specialties. With an increased coordination of the surgical team we observed a significantly increased cooperation of the nursing team (r = 0.36, p = 0.004). Concerning the OT staffs self-reports, the surgical and nursing teams reported higher scores for quality of surgical teamwork during the procedure than their anaesthesia team members. No significant relationships between observed quality of OT teamwork and self-reports were found.

CONCLUSIONS

The German version of OTAS-D is a psychometrically robust method to capture the quality of teamwork in operating theatres. It enables the analyses of teamwork between the surgical, nursing and anaesthesia professions in acute surgical care. Limitations of the first application results are considered. Finally, potential applications for surgical teaching, research and quality management are discussed.
