This is a case report of a 46-year-old man who presented with a painful perineal lump four months after abdominoperineal excision of the rectum (APER) with pre-operative radiotherapy and adjuvant chemotherapy. Perineal hernia (suspected clinically) was confirmed by magnetic resonance imaging, and the patient underwent open Permacol mesh repair via a perineal approach. Symptomatic perineal herniation after surgical resection is a rare phenomenon, and the approach to management remains challenging. Several different surgical approaches and techniques of repair have been described. In this report, we review the literature surrounding the presentation, aetiology and repair of this unusual post-operative complication. Furthermore, our case confirms that closure of the hernial orifice with mesh via a perineal approach is a satisfactory technique.

BackgroundDuodenal webs usually give rise to symptoms of gastric outlet obstruction in infancy, but they occasionally present in adulthood. Case outlineWe report an 82-year-old woman with an unusual cause ofgastric outlet obstruction. Peptic ulcer stricture or carcinoma were suspected, but a CT scan and upper gastrointestinal endoscopy revealed that her symptoms were the result of duodenal webs.The webs were successfully dilated at endosocpy. DiscussionDuodenal webs may rarely account for gastric outlet obstruction in adults. Failure to visualise the second and third parts of the duodenum at endoscopy means that the diagnosis may be missed. Diclofenac and slow-release potassium tablets may have played an aetiological role in the formation of the webs in this patient.

The presence of a gluteal mass should always suggest the possibility of a sciatic hernia. However, in this case, the hernia consisted of an atypical lipoma spanning the greater sciatic foramen. Although lipoma-like well-differentiated liposarcomas have only a low potential for recurrence, the variable nature of fatty tumours demands that patients require regular clinical and radiological review.
