IntroductionA vermiform appendix in an inguinal hernia, inflamed or not, is known as Amyand's hernia. Here we present a case series of four men with Amyand's hernia.Case presentationsWe retrospectively studied 963 Caucasian patients with inguinal hernia who were admitted to our surgical department over a 12-year period. Four patients presented with Amyand's hernia (0.4%). A 32-year-old Caucasian man had an inflamed vermiform appendix in his hernial sac (acute appendicitis), presenting as an incarcerated right groin hernia, and underwent simultaneous appendectomy and Bassini suture hernia repair. Two patients, Caucasian men aged 36 and 43 years old, had normal appendices in their sacs, which clinically appeared as non-incarcerated right groin hernias. Both underwent a plug-mesh hernia repair without appendectomy. The fourth patient, a 25-year-old Caucasian man with a large but not inflamed appendix in his sac, had a plug-mesh hernia repair with appendectomy.ConclusionA hernia surgeon may encounter unexpected intraoperative findings, such as Amyand's hernia. It is important to be prepared and apply the appropriate treatment.

IntroductionInjury of the gallbladder after blunt abdominal trauma is an unusual finding; the reported incidence is less than 2%. Three groups of injuries are described: simple contusion, laceration, and avulsion, the last of which can be partial, complete, or total traumatic cholecystectomy.Case presentationA case of isolated complete avulsion of the gallbladder (near traumatic cholecystectomy) from its hepatic bed in a 46-year-old Caucasian man without any other sign of injury is presented. The avulsion was due to blunt abdominal trauma after a car accident. The rarity of this injury and the stable condition of our patient at the initial presentation warrant a description. The diagnosis was made incidentally after a computed tomography scan, and our patient was treated successfully with ligation of the cystic duct and artery, removal of the gallbladder, coagulation of the bleeding points, and placement of a drain.ConclusionsEarly diagnosis of such injuries is quite difficult because abdominal signs are poor, non-specific, or even absent. Therefore, a computed tomography scan should be performed when the mechanism of injury is indicated.

Our results indicate that lumbar instrumentation using CBT is safe and effective with comparable results to those published for posterior lumbar interbody fusion (PLIF) even with the learning curve of new procedures. Patients who underwent a MIDLF® needed a shorter operative time, and they were mobilized and discharged quicker, with figures almost similar to those from non-instrumented surgery. While in this case series the preoperative ODI and back pain VAS significantly predicted the post-operative variable, the same could not be demonstrated for leg pain, preoperative walking distance, number of pain killers, or the patient BMI. Larger studies with longer follow-up are needed in order to better understand and assess the possible advantages of this technique.

Based on the best available evidence, it appears that cytoreductive resection in adults with supratentorial malignant glioma is associated with improved overall survival as compared with biopsy. However, well-designed prospective studies are needed for more solid conclusions to be drawn.
