An alternative management of a Littré hernia case: food for thought.

AIM: We present a novel approach to a Littré hernia case. CASE REPORT: A 62-year old male presented at our department with a painless mass in the inguinal area and was successfully treated for an inguinal Littré hernia. A Lichtenstein tension-free mesh repair was used without performing simultaneous diverticulectomy. DISCUSSION: Resection of an asymptomatic Meckel's diverticulum remains a controversial issue. In adult population, leaving an accidentally found silent Meckel's diverticula in situ could reduce the risk of postoperative complications without increasing late complications. Mesh-based techniques provide lower recurrence rates compared to non-mesh techniques. CONCLUSIONS: Management of asymptomatic Littré hernias presents a challenge for the operating surgeon. Treatment guidelines should be developed for the optimal management of these patients.

Diverticulitis of the transverse colon manifesting as colocutaneous fistula.

The transverse colon is a particularly rare site for a diverticulum to develop, with only few reports of solitary diverticula described in the literature. Among the reported complications, colocutaneous fistulas appear relatively infrequently. We describe the case of an 80-year-old woman with a solitary diverticulum of the transverse colon presenting as acute diverticulitis with abscess formation in the epigastric region. A fistulous tract was found between the inflamed colon and the skin. A wedge resection of the inflamed colon together with the fistula and the solitary diverticulum was performed followed by primary suturing of the healthy colonic tissue. Despite the sufficient treatment and thorough clearance of the area, the patient died ten days later from ventilator associated pneumonia. Although rare, in patients presenting with a subcutaneous abscess in the abdominal region, there should be a high level of suspicion for active intraperitoneal inflammation derived from complicated diverticular disease given the continuously elevated prevalence of the condition in Western societies. The decision regarding proper management of this clinical state should be based on thorough clinical examination and imaging.

Evasion of No-Hair Theorems and Novel Black-Hole Solutions in Gauss-Bonnet Theories.

We consider a general Einstein-scalar-Gauss-Bonnet theory with a coupling function f(ϕ). We demonstrate that black-hole solutions appear as a generic feature of this theory since a regular horizon and an asymptotically flat solution may be easily constructed under mild assumptions for f(ϕ). We show that the existing no-hair theorems are easily evaded, and a large number of regular black-hole solutions with scalar hair are then presented for a plethora of coupling functions f(ϕ).
