[Preperitoneal Umbilical Hernia Mesh Plasty (PUMP): Indications, Technique and Results]. / Präperitoneale umbilikale Netzplastik (PUMP): Indikationen, Technik und Resultate.

BACKGROUND: The principle of the preperitoneal umbilical mesh plasty (PUMP) technique is placement of the prosthesis in the extraperitoneal space, posterior to the rectus muscles, followed by ventral fascia closure. Difficulties can arise from preperitoneal dissection, mesh insertion, deployment, and positioning. METHODS: 81 elective patients underwent preperitoneal repair of primary umbilical or epigastric hernias sized from 2 - 4 cm between January 2015 and March 2018 and were prospectively collected in the Herniamed database and retrospectively analysed. The same general technique was applied, but over time three different types of mesh devices were used. The experience from these cases and the gradual change between the implants during the observation period is described in this study. RESULTS: No intraoperative complications were recorded. Postoperative complications occurred in 6 of 81 patients (7.4%) with the need for unplanned re-operation in 3 cases. Seventy-six of 81 patients (93.8%) attended the one year follow-up evaluation. Three of 76 patients (3.9%) suffered recurrence and five patients (6.6%) requires treatment for chronic pain. CONCLUSION: Surgeons must work with the implant that best suits their patients' needs and that also provides good results and adequate working comfort. The PUMP technique performs well for ventral hernias sized between 2 and 4 cm without the need of midline reconstruction due to diastasis of the rectus muscles. It enables a local extraperitoneal mesh augmentation without the risk of intraperitoneal complications. PUMP repair lowers the risk of recurrence in comparison with suture repair without increasing the risk of complications.

Role of Pepsin and Oropharyngeal pH-Monitoring to Assess the Postoperative Outcome of Patients with Laryngopharyngeal Reflux: Results of a Pilot Trial.

BACKGROUND: The aim of this study was to evaluate the value of salivary pepsin and oropharyngeal pH-monitoring to assess the surgical outcome of patients with laryngopharyngeal reflux (LPR). MATERIALS AND METHODS: Twenty consecutive patients with LPR despite proton pump inhibitor treatment received laparoscopic antireflux surgery. Twenty-four hour esophageal pH-monitoring (multichannel intraluminal impedance monitoring [MII]-pH) and esophageal manometry (high-resolution manometry) data were documented preoperatively and at 3-month follow-up. An ears, nose and throat (ENT) examination was performed, including assessment of Belafsky Reflux Finding Score (RFS). Clinical symptoms were evaluated with the Belafsky Reflux Symptom Index (RSI) and the Gastrointestinal Quality of Life Index (GIQLI). Simultaneous to the MII-pH and collection of saliva samples, detection of oropharyngeal reflux events was performed. Treatment failure was defined as postoperative pathologic RFS or RSI score and improvement of GIQLI of <10 points, despite showing a normal DeMeester score. RESULTS: At baseline, all patients had a pathological ENT examination, RSI score, and MII-pH data. All patients showed postoperatively a normal DeMeester score (mean 6.39 ± 4.87). Five patients were defined as treatment failures with a change of pepsin concentration from median 157.0 (95% confidence interval [CI]: 0-422) to 180.7 (95% CI: 0-500). In patients defined as treatment success, median pepsin value decreased from 206.3 (95% CI: 89-278) to 76.0 (95% CI: 55-205); (P = .093). Oropharyngeal pH-monitoring data showed no significant change in both groups. CONCLUSION: Salivary pepsin could be a marker for treatment success, while oropharyngeal pH-monitoring seems to be inadequate in these terms. However, larger studies are required to reach firm conclusions.
