Most cases of Meckel’s diverticulum (MD) are asymptomatic and discovered by chance. Management of MD is controversial. The authors describe an exceptional case of intestinal obstruction caused by a giant MD in a patient who had previously undergone appendectomy. A review of the contradictory literature on this subject leads to the conclusion that careful consideration of clinical and morphological data (patient's age, ASA score, the surgical procedure to be performed, morphology and position of the MD, any fibrotic bands) is required before deciding whether or not to resect an asymptomatic MD.

Small bowel obstruction (SBO) is a very common condition, in the vast majority of cases caused by post-operative adhesions. It often requires surgical treatment. Traditionally, this consisted of a laparotomy, but nowadays a laparoscopic approach is also possible. This study discusses 24 cases of SBO and compares them with literature data. Successful complete laparoscopic treatment was feasible in 9 patients, while conversion to laparoscopically-assisted surgery or laparotomy was required for the others.

We present the case of a patient with a double adenocarcinoma of the right colon and sigma associated with a bilateral infiltrating ductal breast carcinoma. Sigma and caecum bowel cancers were diagnosed at colonoscopy, with computerized tomography staging, while breast cancer was found with screening mammography. Following right hemicolectomy , sigmoidectomy and bilateral mastectomy the histology confirmed the presence of colonic adenocarcinoma and infiltrating and in situ lobular cancer. This case report reviews the treatment of synchronous neoplasia.

Introduction. Endoscopic hernia repair methods have become increasingly popular over the past 15 years. Nonetheless, there is no consensus regarding an optimal fixation method. Transabdominal sutures and titanium tacks or staples are the most traditional ones. Case report. We present a case of mechanic small bowel obstruction due to mesh migration occurring one year and a half after incisional hernia repair with polytetrafluoroethylene mesh fixed by spiral tacks. Discussion. Titanium spiral tacks are dangerous because of their sharp components, which can damage organs such as the small intestine, by causing microperforations. The type of prosthesis used has also contributed to the intraluminal migration, since polytetrafluoroethylene mesh is very flexible and poorly integrates in the abdominal wall. Conclusion. A prosthesis of a different material combined with a different fixation system such as absorbable tacks, biological glue, or mechanical tacks without sharp components, would have obviated mesh migration. .

The authors describe a clinical case of a patient with neuroendocrine carcinoma of the lung diagnosed after the onset of an intestinal obstruction from an ileal metastasis. A review of literature reveals that the incidence of symptomatic gastro-intestinal metastases from lung cancer has been estimated to be about 2-3% and is exceedingly rare that the intestinal symptoms may be the initial presentation of cancer of the lung. The authors emphasize the difficulty of preoperative diagnosis of gastro-intestinal metastases which is made, almost always, too late because of the lack of specific symptoms. In our case, on account of the computed tomography, we leaned towards the diagnosis of lymphoma because of the double mediastinal and abdominal localization. Furthermore, this diagnosis was supported by the fact that the pulmonary lesion did not have clear radiological features of a lung cancer. The prognosis is poor because once intestinal metastases occur, other metastatic sites, which would make surgery only a palliative measure, are already present. The review of the literature shows that the average survival rate of these patients is 136 days. In our case the patient survived 277 days.

Background: Peripheral nerve sheath tumours are benign or malignant. Schwannoma is a benign peripheral nerve sheath tumour originating from Schwann cells that slowly grows eccentrically to the nerve axis. Malignant transformation of a schwannoma is rare. Case presentation: A 73-year-old woman who presented to our medical service with other medical problems was diagnosed with a tumour of the lower leg (a small mass neglected by the patient for about 10 years). The ultrasound features of the tumour suggested it was a schwannoma. The tumour was resected and histopathological assessment revealed a schwannoma with areas of malignant peripheral nerve sheath tumour transformation.

Objectives: We report a fatal case of neuroleptic malignant-like syndrome, which occurred as a consequence of paralytic bowel in a 72-year-old woman on treatment with antiparkinson medication. Case description: Contrast enhanced computerized tomography of the chest and abdomen demonstrated the presence of paralytic bowel. Results: The patient died. Conclusions: Physicians involved in the treatment of patients affected by Parkinson’s disease should take into consideration the possibility of dopaminergic drug malabsorption due to paralytic bowel as a possible cause of neuroleptic malignant-like syndrome.

Malignant otitis externa (MOE) is an aggressive but benign entity which evolves into skull base osteomyelitis. An 81-year-old female patient was admitted for left hemiparesis and homonymous hemianopia. She complained of headache radiating to the right cervical area. A recent history of recurrent otitis media was present. Head and neck imaging showed an ischemic infarction (right temporo-occipital) and a parapharyngeal soft tissue mass originating in an external and medial ear infection. Culture samples revealed Pseudomonas aeruginosa infection leading to the diagnosis of Malignant otitis externa (MOE). Parenteral antibacterial therapy and hyperbaric oxygen therapy resulted in improvement.
