Chronic ileitis with transmural migration of ingested foreign body treated by laparoscopy.

BACKGROUND: Ingestion of foreign bodies such as fish bone or chicken bone is relatively common in adults; however, resultant transmural migration is extremely rare. METHODS: We present a case of a 79-year-old woman with chronic low-grade abdominal pain, worsening over the last 4 days. Computed tomography revealed segmental small bowel wall thickening with chronic inflammation suggestive of Crohn's ileitis and oral steroids were commenced; only later, ingestion of a foreign body was suspected. RESULTS AND CONCLUSION: At diagnostic laparoscopy, a linear foreign body resembling a wooden splinter was identified. It had partly migrated through the chronically inflamed bowel wall without causing perforation or abdominal contamination. It was removed laparoscopically without an enterotomy or bowel resection. Microscopy revealed non-viable bone, likely fish or chicken bone. The patient made an uneventful recovery and was discharged 3 days later. Herein we emphasise on the differential diagnosis and presentation of chronically ingested foreign bodies, as well as the feature of chronic ileitis with uncomplicated transmural migration of the ingested foreign body that was treated laparoscopically without an enterotomy.

Benign ancient schwannoma of the abdominal wall: an unwanted birthday present.

BACKGROUND: There has been a recent growth in the use of whole body Computerised Tomography (CT) scans in the private sector as a screening test for asymptomatic disease. This is despite scant evidence to show any positive effect on morbidity or mortality. There has been concern raised over the possible harms of the test in terms of radiation exposure as well as the risk and anxiety of further investigation and treatment for the large numbers of benign lesions identified. CASE PRESENTATION: A healthy 64 year old lady received a privately funded whole body CT scan for her birthday which revealed an incidental mass in the right iliac fossa. This was investigated with further imaging and colonoscopy and as confident diagnosis could not be made, eventually excised. Histology demonstrated this to be a benign ancient schwannoma and we believe this to be the first reported case of an abdominal wall schwannoma in the English literature CONCLUSIONS: Ancient schwannomas are rare tumours of the peripheral nerve sheaths more usually found in the head, neck and flexor surfaces of extremities. They are a subtype of classical schwannomas with a predominance of degenerative changes. Our case highlights the pitfalls of such screening tests in demonstrating benign disease and subjecting patients to what turns out to be unnecessary invasive investigation and treatment. It provides evidence as to the consequences of the large number of false positive results that are created by blind CT scanning of asymptomatic patients i.e. its tendency to detect pseudodiesease rather than affect survival rates. Should the number of scans increase there may be an unnecessary burden on NHS resources due to the large numbers of benign lesions picked up, that are then referred for further investigation.

Minimally Invasive Circumferential Hiatal Dissection for the Treatment of Adenocarcinoma of the Distal Esophagus and Esophago-gastric Junction: Technical Considerations Combined With Histopathological Outcomes.

BACKGROUND/AIM: Circumferential resection margin involvement is an independent prognostic factor in patients with adenocarcinoma of the distal esophagus and esophago-gastric junction. However, there is currently no consensus on the extent and the technique of hiatal dissection. We describe a minimally invasive technique of circumferential hiatal dissection for adenocarcinoma of the distal esophagus and esophago-gastric junction with its related histopathological results. PATIENTS AND METHODS: A prospective study of 40 consecutive patients undergoing hybrid (laparoscopic/thoracotomic) or totally minimally invasive Ivor-Lewis esophagogastrectomy over a period of 21 months was conducted. Dissection of the hiatus included peri-esophageal surrounding tissues in a cylindrical fashion maximizing the distance from the oesophageal wall. Crural muscle fibers and pleura bilaterally, pericardial fat anteriorly and pre-aortic tissue posteriorly were excised en bloc. Histopathological results particularly focused on involvement of the circumferential resection margin. Neoadjuvant chemotherapy was given to 24 (60%) patients. RESULTS: Complete histological clearance (R0) was achieved in 92.5% (n=37) according to the criteria of the College of American Pathologists and in 87.5% (n=35) according to those of the Royal College of Pathologists. In pT3 tumors (n=22), the circumferential resection margin was negative in 20 patients (91%) according to the College of American Pathologists, and in 17 (77%) according to the Royal College of Pathologists. CONCLUSION: Adoption of this safe and reproducible technique might reduce the incidence of circumferential resection margin involvement and improve pathological outcomes. In addition, there may be positive implications for training and quality control.

Endometrial intraepithelial carcinoma: a case report and brief review.

This case report describes the precursor lesion of uterine papillary serous carcinoma (UPSC). A 65-year-old post-menopausal female presented with prolapse and vaginal discharge and underwent a hysterectomy revealing an atrophic endometrium, highly atypical endometrial glands, the lining cells of which showed pseudostratification, hobnailing, a high nuclear to cytoplasmic ratio, and prominent nucleoli. A p53 immunoreactivity score of 8 and a MIB-1 index of 80% was obtained leading to a diagnosis of endometrial intraepithelial carcinoma (EIC). Since serous EIC is commonly associated with extra-uterine serous carcinoma, it is a uniquely aggressive precursor lesion. Molecular studies support the hypothesis that EIC is a precursor of both uterine and extra-uterine invasive serous carcinomas. This is why the treatment protocol for EIC cases is total abdominal hysterectomy (TAH), accompanied by a staging procedure. In our patient, EIC was limited to the endometrium; associated with an excellent clinical outcome.

Latent Progression Pediatric Scrotal Schwannoma. A Case Report.

We report the case of a 24 year old patient being diagnosed with scrotal schwannoma initially presenting at age 9. To our knowledge, this is the first case with such an early onset. The patient underwent an uncomplicated surgical excision. We are also reviewing the literature on scrotal schwannoma.

Urinary Bladder Paraganglioma and Concomitant Metastatic Lung Cancer. A Case Report.

We present a case of an organ confined urinary bladder paraganglioma and concomitant metastatic lung cancer to the liver diagnosed on a 66 year old man initially though to be metastatic bladder cancer. The patient was referred to our hospital for frank hematuria and a single solid bladder tumor was identified at flexible cystoscopy. We are also reviewing the literature on the diagnostic and therapeutic approach of extra-adrenal phaeochromocytoma.

Fibro-osteochondroma of the uterus.

A case of a uterine fibro-osteochondroma in a 61-year-old woman with postmenopausal bleeding was presented. Ultrasound revealed a calcified lesion in the posterior wall of the uterus and a hysterectomy was performed. Histopathologic examination showed a well-circumscribed triphasic tumor composed of peripheral lobules of mature hyaline cartilage and foci of trabecular bone with a core of loosely arranged fibroblast-like, spindle cells. This is the second reported case of fibro-osteochondroma, which has been described only in the uterus. Diagnosis requires thorough histopathologic examination to exclude metaplasia within a leiomyoma or uterine sarcoma. It is histologically benign and complete excision should be curative.
