Strangulated Richter's incisional hernia presenting as an abdominal mass with necrosis of the overlapping skin. A case report and review of the literature.

Although rare, clinicians must be alerted of Richter hernias in patients presenting with innocuous gastrointestinal obstruction symptoms, synchronous with an erythematous hernia. An incarcerated incisional hernia located in a previous laparoscopic insertion site further raises suspicion, while timely surgical management is essential to avoid bowel perforation or resection.

Surgical management of a giant parathyroid adenoma through minimal invasive parathyroidectomy. A case report.

INTRODUCTION: Primary hyperparathyroidism is a common endocrine disorder mostly associated to parathyroid adenomas. Although those tend to be small in size, rare cases of giant parathyroid adenomas may be present. CASE PRESENTATION: A 42year old female was admitted in our department due to weakness and vague abdominal pain for the past 8 months. Preoperative laboratory exams indicated primary hyperparathyroidism as a cause to her symptomatology, with elevated values of parathormone and normal values of serum calcium. Ultrasound scan and 99m Tc-MIBI of her cervical region uncovered a giant 3×2cm parathyroid adenoma, located in the lower left thyroid lobe. Despite its size, the gland was successfully removed through implementation of minimal invasive parathyroidectomy. She was uneventfully discharged on the 1st postoperative day. DISCUSSION: Although a common reason for developing hyperparathyroidism, parathyroid adenomas may rarely present with exaggerated dimensions and weight. Physical examination is usually unremarkable, while patients may present with symptomatology associated with elevated calcium levels. Treatment of this medical condition consists of surgical removal of the pathologic parathyroid gland either by bilateral neck exploration or through minimal invasive parathyroidectomy. Preoperative localization plays an important role in the second case, since the method focuses on resection of a pre-op marked hyperactive parathyroid gland, through a small incision. CONCLUSION: Clinicians must be alerted of hyperparathyroidism in patients presenting with calcium associated symptomatology. Diagnosis is straightforward through laboratory exams, while surgery offers the only permanent treatment option.

Intra-abdominal myositis ossificans in an asymptomatic patient during closure of a Hartmann's colostomy.

Intra-abdominal myositis ossificans, also known as heterotopic mesenteric ossification, defines the formation of bone-like lesions inside the abdominal cavity. It is a rare medical condition, usually following abdominal surgery or trauma. A 55-year-old male presented for closure of a Hartmann's colostomy, created 6 months ago because of sigmoid adenocarcinoma. Intraoperative findings consisted of an elongated bone-like lesion attached on the peritoneum and protruding inside the abdominal cavity, while two more stiff calcified nodules were found in the mesocolon. All lesions were excised. The presence of a hard consistency sigmoid stump led to cancelation of the operation. Heterotopous bone formation constitutes a challenging surgical condition, since its clinical presentation is innocuous and repetitive surgery acts a stimuli for additional bone creation. Computed tomography scan plays a major role in its diagnosis, while nonsteroidal anti-inflammatory drugs and cimetidine are helpful in preventing further recurrence of the disease.
