Pyloric Obstruction Caused by an Inflammatory Fibroid Polyp.

This is a case report of a 57-year-old woman who presented with abdominal pain and vomiting over a period of two months. Upper gastrointestinal endoscopies and biopsies were inconclusive, while abdomen computed tomography (CT) scan revealed a large mass arising from the pyloric antrum measuring about 6 × 4.8 cm imitating gastrointestinal stromal tumor (GIST). The patient underwent a laparotomy, and the tumor was totally resected with well-defined borders. The histopathological analysis revealed the mass to be an inflammatory fibroid polyp (IFP).

Emergency pancreatoduodenectomy (whipple procedure) for massive upper gastrointestinal bleeding caused by a diffuse B-cell lymphoma of the duodenum: report of a case.

We herein report a rare case of a massive upper gastrointestinal (GI) bleeding, caused by high-grade diffuse B-cell lymphoma of the duodenum, secondary to immunoproliferative small intestinal disease (IPSID) and treated with an emergency partial pancreatoduodenectomy. A 42-year-old man was admitted to our hospital because of hematemesis. Upper GI endoscopy was unrevealing because of the copious bleeding. Initially, the patient underwent conservative treatment, thus resulting in the temporary cessation of the bleeding. Later, the hemorrhage massively relapsed. An urgent abdominal ultrasound raised the suspicion of a large, possibly bleeding, neoplasm of the duodenum, which was finally confirmed by abdominal computed tomography. The patient underwent an emergency laparotomy, during which a partial pancreatoduodenectomy was performed (Whipple procedure). Histologically, the tumor was a high-grade B-cell lymphoma of the duodenum. The nearby small intestinal mucosa was suggestive of IPSID. A massive upper GI hemorrhage from a high-grade B-cell non-Hodgkin lymphoma of the duodenum, which develops secondary to IPSID, is a very rare clinical demonstration of this disease. Our case is one of the few reports in the English literature, for which the Whipple procedure has been performed as a curative treatment.

Surgical management of mediastinal lesions.

Mediastinal tumors and cysts are relatively uncommon lesions requiring histologic confirmation. This retrospective study reports the experience of our department in the diagnosis and treatment of mediastinal lesions. Mediastinal lesions that were surgically treated in 200 patients aged 6-84 years, during a period of 28 years, were included in this series. Sixty patients had an apparently non-resectable lesion or lymphadenopathy of the anterior superior mediastinum. They had an anterior mediastinotomy and biopsy of the mediastinal lesion. No perioperative deaths were recorded in those patients. There were recorded 5 (8.3%) complications. Histological diagnosis was established in all patients: lymphoma (n = 21), metastatic carcinoma (n = 16), thymic lesions (n = 10), germ cell tumor (n = 3), other lesions (n = 10). The remainder 140 patients underwent a resection of the mediastinal lesion. One (0.7%) perioperative death and 21 (15%) complications were recorded. The histological diagnosis of the excised lesions was: thymic lesions (n = 60), neural tumors (n = 21), thyroid lesions (n = 14), bronchial cysts (n = 12), pericardial cysts (n = 10), germ cell tumors (n = 6), other lesions (n = 17). Our results are compared favorably with those reported in international literature. Surgery is the management of choice for patients with mediastinal lesions. It allows for establishing certain histological diagnosis and curative excision of the lesion, when it is necessary, with low operative risk.

Perforated carcinoma of the sigmoid colon in an incarcerated inguinal hernia: report of a case.

Perforation of the large bowel due to benign or malignant disease in an inguinal hernia is very rare, but should be considered as a potential cause of strangulated hernias. A 79-year-old man with a 2-day history of scrotal swelling and pain in the left side associated with fever and chills was brought to our Emergency Department, where he was classified as American Society of Anesthesiologists IVE. A large left incarcerated scrotal hernia was diagnosed and surgical exploration was performed using local infiltration anesthesia. A standard oblique inguinal incision was made, revealing perforation of the sigmoid colon due to cancer. A 40-cm segmental resection of the sigmoid colon was done, and a double-barrel colostomy was made through the inguinal incision. This surgical strategy involving construction of a double-barrel colostomy through the inguinal hernia incision could be an alternative method of managing such critically ill patients.

Metastatic melanoma in the gallbladder: report of a case.

Both primary and secondary gallbladder melanomas are rare and, when a solitary melanoma is found in the gallbladder, it is difficult to determine if it is primary or metastatic disease. We report the case of a young woman found to have a single metastatic gallbladder melanoma. Surgical removal of a solitary metastatic focus remains the treatment of choice for isolated metastasis of a malignant melanoma; however, the effectiveness of complementary chemotherapy and immunotherapy is still being examined.

Diagnosis and treatment of intracystic breast carcinomas.

Cystic breast masses are very common in female patients attending breast clinics. Most of them are benign and managed by simple aspiration. We reviewed histology records for the last 12 years to find patients with cystic breast carcinomas and to evaluate special clinical signs that may help to identify patients with this rare entity. Eighteen patients with cystic breast carcinomas were found among 1510 new breast cancer patients (1.19%) who were seen at our Breast Unit during this period. Ten had intracystic papillary carcinoma (0.66% of all breast cancers), seven had cystic degeneration of ductal carcinoma, and one had a mucinous carcinoma. The diagnosis of intracystic papillary carcinoma was based on cyst fluid cytology and breast imaging in most patients and on open breast biopsy in two cases only. The prognosis of our cystic breast carcinoma patients was excellent regardless of the specific histologic type of the tumor. We conclude that cysts in postmenopausal women should be viewed with suspicion. Bloodstained aspirated cyst fluid should be sent for cytology and breast imaging should be carried out in all these cases. Residual mass after cyst aspiration is also an indication for open biopsy.

Clinical implications of small bowel diverticula.

BACKGROUND: Small bowel diverticula are usually asymptomatic and rare. Their importance is based on the fact that they carry the risk of serious complications. OBJECTIVE: To study the implications and the therapeutic approach regarding small bowel diverticulosis. METHODS: The medical records of 54 patients with diverticular disease of the small bowel, including Meckel's and duodenum diverticula, were retrospectively reviewed. The mean age of the 32 male and 22 female patients was 53.2 years. RESULTS: Diverticula were found in the duodenum in 11 cases, in the jejunum and ileum in 21 cases, and with Meckel's diverticula in 22 cases. In 24% of the patients the diverticula were multiple. The most common clinical symptom was abdominal pain, in 44.4%. Most of the duodenum diverticula were asymptomatic; 47.6% of the patients with diverticular disease located in the jejunum and ileum presented with chronic symptoms. The overall diagnostic rate for symptomatic diverticula before surgery was 52.7%; in 33.3% diverticula were found incidentally during other diagnostic or therapeutic procedures. Forty-one patients were managed surgically. 15 patients were operated on urgently because of infection or rupture, 4 patients for bleeding, 5 patients for intestinal obstruction, and one patient for jaundice. CONCLUSIONS: The incidence of asymptomatic small bowel diverticula is difficult to ascertain. Patients with Meckel's and duodenal diverticula are usually asymptomatic, while the majority of jejunal and ileal diverticula patients present with chronic symptoms. The pre-operative diagnostic rate is higher for duodenal diverticula. Small bowel diverticula do not require surgical treatment unless refractory symptoms or complications occur.
