Effects of neurosurgical titanium mesh on radiation dose

The purpose of this study was to determine the dosimetric impact of a neurosurgical titanium mesh in patients treated with 6- and 18-MV photon beams. The effects of a 0.4-mm-thick titanium mesh on the dose profile at 3 regions within a solid water phantom were measured using extended dose range-2 (EDR2) film for 6- and 18-MV photon beams. All measurements were performed with the titanium mesh placed at a depth of 1.5 cm in the phantom. Films were exposed immediately above the mesh, immediately below the mesh, and at a depth of 5 cm from the surface of the phantom. The films were scanned using a scanning densitometer. In the region directly above the titanium mesh, there was an increase in dose of 7.1% for 6-MV photons and 4.9% for 18-MV photons. Directly below the titanium mesh, there was an average decrease in dose of 1.5% for 6-MV photons and an increase of 1.0% for 18-MV photons. At 5-cm depth, for 6- and 18-MV photons, there was a decrease in dose of 2.2% and 0.6%, respectively. We concluded that for cranial irradiation with high-energy photons, the dosimetric impact of a 0.4-mm titanium mesh is small and does not require modification in treatment parameters.     

A review of incisional hernia repairs: preoperative weight loss and selective use of the mesh repair

At the Shouldice Clinic pre-operative weight loss is used prior to incisional hernia repairs. Mesh repair is selectively used, based on specific hernia characteristics. A series of 236 patients were reviewed and followed up for 36 months. Data were available on 188 patients (80%). There were 15 recurrences (8%). The number of obese patients was reduced from 67 (35.6%) to 25 (13.3%) through the weight loss program. The hernia diameter, gastrointestinal complications, and surgical site infection were significantly related to recurrence but not the type of repair, obesity, location, or previous recurrences. The risk factors of incisional hernias include size, intestinal complications and infections. A selective use has a comparable result to the exclusive use of mesh repair. Weight reduction has yet to be shown to affect the rate of recurrence, and further prospective studies are required.

Hernia repair in elderly patients under unmonitored local anaesthesia is feasible

Background: There is a growing interest in the use of local anaesthesia for inguinal hernia repair. It certainly seems to be an acceptable alternative for the elderly. Supporting intravenous sedation, however, still requires monitoring, anaesthetic personnel and some preparations for the patient. Therefore we set up a feasibility study of hernia repair under local anaesthesia without intravenous sedation or monitoring in elderly patients. Method: A total of 62 patients (aged 65 years or more) with unilateral inguinal hernia received a Mesh Plug Repair. Prospectively collected data included procedure-related complications and information on pain and quality of life as measured by Short Form 36. Results: No procedure-related complications were noted. Comparing the preoperative scores, the SF-36 on day 14 (n=61) did not differ significantly. After a median follow-up of ten months (n=54), significantly higher scores were found for scales of physical and emotional role and pain (all p<0.05). Twenty-two patients reported some form of pain (40.7%). 94.4% of the patients would recommend the procedure when asked. Conclusion: The results of this study indicated that Mesh Plug Repair performed under unmonitored local anaesthesia with no intravenous sedation is a feasible alternative for elderly patients. It has advantages for the medical organization without disadvantages for the patient.     

Parapubic hernia: case report and review of the literature

Parapubic hernia is considered rare, with 18 hernias described in five articles published since 1971. The hernia results from iatrogenically or traumatically detached rectus abdominis muscles at the pubic bone and presents a therapeutic challenge because there is no strong aponeurotic anchoring structure in the defect's caudal aspect. We describe a patient with a large parapubic hernia repaired by a combined preperitoneal and onlay prosthetic method. This report adds another dimension to the prosthetic repair options in parapubic hernias and illustrates the effectiveness of the tension-free repair principle in their definitive management.

Laparoscopic mesh repair of incisional hernia: an alternative to the conventional open repair?

Background Tension-free incisional hernia repair using alloplastic material increasingly replaces conventional repair techniques. This change resulted in a decreased recurrence rate (50% vs. 10%, respectively). Recently, laparoscopic approaches for the intraperitoneal tension-free mesh application have been introduced. The decreased trauma at the incision site and the reduction in wound infections appear to be the main advantages. The aim of the present study was to evaluate the early and long-term complications as well as patients’ contentment. Methods Laparoscopic hernia repair with intraperitoneal polytetrafluroethylene (PTFE) mesh implantation was performed on 62 patients at the Klinikum Grosshadern between 2000 and 2005 (29 males, 33 females age 60.7). Intra- and postoperative complications were registered prospectively and retrospectively analyzed. In addition, 57 patients were evaluated for recurrence, postoperative pain and patient contentment (median follow-up 409 days). Results A low complication rate was observed in our patient collective. One trocar bleeding occurred. Three patients presented with wound hematoma. The recurrence rate was 8% (2/25). Sixty-two percent of the patients were free of complaints postoperatively. Eighty-five percent would once again choose the laparoscopic approach for incisional hernia repair. Conclusion The laparoscopic technique was associated with a low recurrence rate, a small rate of wound infections and high patient comfort. Thus, the laparoscopic approach for mesh implantation appears to be a safe and effective method for the treatment of incisional hernias. The efficiency for laparoscopic intraperitoneal mesh implantation, however, should be further evaluated within a prospectively randomized multicenter trial. M. Stickel and M. Rentsch contributed equally.
