Cecal obstruction due to primary intestinal tuberculosis: a case series.

INTRODUCTION: Primary intestinal tuberculosis is a rare variant of tuberculosis. The preferred treatment is usually pharmaceutical, but surgery may be required for complicated cases. CASE PRESENTATION: We report two cases of primary intestinal tuberculosis where the initial diagnosis was wrong, with colonic cancer suggested in the first case and a Crohn's disease complication in the second. Both of our patients were Caucasians of Greek nationality. In the first case (a 60-year-old man), a right hemicolectomy was performed. In the second case (a 26-year-old man), excision was impossible due to the local conditions and peritoneal implantations. Histopathology revealed an inflammatory mass of tuberculous origin in the first case. In the second, cell culture and polymerase chain reaction tests revealed Mycobacterium tuberculosis. Both patients were given anti-tuberculosis therapy and their post-operative follow-up was uneventful. CONCLUSIONS: Gastrointestinal tuberculosis still appears sporadically and should be considered in the differential diagnosis along with other conditions of the bowel. The use of immunosuppressants and new pharmaceutical agents can change the prevalence of tuberculosis.

Massive variceal bleeding secondary to splenic vein thrombosis successfully treated with splenic artery embolization: a case report.

INTRODUCTION: Splenic vein thrombosis results in localized portal hypertension called sinistral portal hypertension, which may also lead to massive upper gastrointestinal bleeding. Symptomatic sinistral portal hypertension is usually best treated by splenectomy, but interventional radiological techniques are safe and effective alternatives in the management of a massive hemorrhage, particularly in cases that have a high surgical risk. CASE PRESENTATION: We describe a 23-year-old Greek man with acute massive gastric variceal bleeding caused by splenic vein thrombosis due to a missing von Leiden factor, which was successfully managed with splenic arterial embolization. CONCLUSIONS: Interventional radiological techniques are attractive alternatives for patients with a high surgical risk or in cases when the immediate surgical excision of the spleen is technically difficult. Additionally, surgery is not always successful because of the presence of numerous portal collaterals and adhesion. Splenic artery embolization is now emerging as a safe and effective alternative to surgery in the management of massive hemorrhage from gastric varices due to splenic vein thrombosis, which often occurs in patients with hypercoagulability.

Acute contact appendicitis due to a migrated pericardial drain: a case report.

INTRODUCTION: The literature is replete with articles of foreign-body appendicitis and periappendicitis, but to our knowledge there are only two reports of extraintestinal foreign bodies causing contact appendicitis. CASE PRESENTATION: A 47-year old woman presented to the emergency department with a 24-hour history of right iliac fossa pain, nausea and vomiting, high fever and palpable right iliac fossa mass. The patient had an anamnestic of systemic lupus erythematosus, that caused acute pericarditis with effusion, that was treated with pericardiotomy and a pericardial drain. The laboratory tests showed leukocytosis The plain abdomen film showed no radiologic signs corresponding to acute abdomen, while the computed tomography revealed a radio-opaque formation in the right iliac fossa, corresponding to the palpable mass. Exploratory laparotomy revealed a pericardial drain. The microbiologic analysis of the abscess revealed Salmonella. The postoperative course of the patient was uneventful. CONCLUSION: Acute appendicitis due to a foreign body, without an anamnestic of either surgery or injury may cause a severe diagnostic dilemma. The computed tomography images may lead to logic riddles that have to be solved by an explorative laparotomy. Foreign bodies rarely cause acute abdomen, nevertheless the probability has to be considered when an interventional technique has been applied even if the location of the intervention is far from the abdominal cavity.

Intra-abdominal pressure alterations after large pancreatic pseudocyst transcutaneous drainage.

BACKGROUND: Acute pancreatitis leads to abdominal hypertension and compartment syndrome. Weeks after the episodes pancreatic fluids sometimes organize to pseudocysts, fluid collections by or in the gland. Aims of the present study were to evaluate the intra-abdominal pressure (IAP) induced by large pancreatic pseudocysts and to examine the effect of their transcutaneous drainage on IAP. METHODS: Twenty seven patients with a pancreatic pseudocyst were included. Nine patients with pseudocysts greater than 1l (group A) had CT drainage and eighteen (volume less than 1l) were the control group. The measurements of group A were taken 6 hours before and every morning after the drainage, while for group B, two measurements were performed, one at the day of the initial CT and one 7 days after. Abdominal compliance (Cabd) was calculated. Data were analyzed using student's t-test. RESULTS: Baseline IAP for group A was 9.3 mmHg (S.D. 1.7 mmHg), while the first post-drainage day (PDD) IAP was 5.1 mmHg (S.D. 0.7 mmHg). The second PDD IAP was 5.6 mmHg (S.D. 0.8 mmHg), the third 6.4 mmH (S.D. 1.2 mmHg)g, the fourth 6.9 mmHg (S.D. 1.6 mmHg), the fifth 7.9 mmHg (S.D. 1.5 mmHg), the sixth 8.2 mmHg (S.D. 1.4 mmHg), and the seventh 8.2 mmHg (S.D. 1.5 mmHg). Group B had baseline IAP 8.0 mmHg (S.D. 1.2 mmHg) and final 8.2 mmHg (S.D. 1.4 mmHg). Cabd after drainage was 185.6 ml/mmHg (SD 47.5 ml/mmHg). IAP values were reduced between the baseline and all the post-drainage measurements in group A. IAPs seem to stabilize after the 5th post-drainage day. Baseline IAP was higher in group A than in group B, while the two values, at day 7, were equivalent. CONCLUSION: The drainage of large pancreatic pseudocyst reduces IAP. Moreover, the IAP seems to rise shortly after the drainage again, but in a way that it remains inferior to the initial value. More chronic changes to the IAP are related to abdominal cavity's properties and have to be further studied.

Inguinal endometriosis: three cases and literature review.

Three cases of endometriosis infiltrating the round ligament are presented. The initial diagnosis was irreducible hernia, since this rare nosologic entity often causes unusual preoperative symptoms and diagnostic problems. Diagnosis is frequently made by histologic examination. The rarity of inguinal endometriosis should not exclude it from a possible diagnosis in cases with a painful mass in the inguinal region in a fertile woman, especially if the groin mass is associated in size and tenderness with menstrual variability. Surgery is the treatment of choice and is curative; laparoscopy is suggested during the same operation to evaluate the intraperitoneal conditions.

Hematemesis, a very rare presentation of solid pseudo-papillary tumors of the pancreas: a case report.

INTRODUCTION: Solid pseudo-papillary tumors of the pancreas are rare and typically present in young female patients. They are slowly growing masses that may attain large size, and are of low malignant potential. Surgical resection is usually curative. CASE PRESENTATION: A 71-year-old woman presented to the emergency department with an episode of hematemesis but was otherwise hemodynamically stable. Emergency gastroscopy revealed a bleeding mass projecting to the duodenum. Fluid, blood and electrolyte resuscitation followed. Computed tomography revealed a small mass in the head of the pancreas. A Whipple operation was performed. Pathology revealed a solid pseudo-papillary tumor. The postoperative course of the patient was uneventful and no recurrence was present a year after the operation. CONCLUSION: In our case, the most noteworthy observations concern the small size of the tumor, the age of the patient and the presenting symptom. However, pancreaticoduodenectomy in a 71-year-old woman is a major effort and should only be undertaken by centers and surgeons experienced in complex hepatobiliary surgery. Furthermore, the unique nature of this case reminds every clinician that each patient has to be considered separately and with extreme caution.

Anterior chest wall tuberculous abscess: a case report.

The granulomatous inflammation of tuberculosis usually involves the lungs and the hilar lymph nodes. Musculoskeletal tuberculosis (TB) occurs in 1-3% of patients with TB, while TB of the chest wall constitutes 1% to 5% of all cases of musculoskeletal TB. Furthermore, nowadays it is rarer to find extrapulmonary TB in immunocompetent rather that non-immunocompetent patients. The present case reports a fifty-six-year-old immunocompetent man with an anterior chest wall tuberculous abscess. The rarity of the present case relates both to the localization of the tuberculous abscess, and to the fact that the patient was immunocompetent. The diagnosis of musculoskeletal tuberculous infection remains a challenge for clinicians and requires a high index of suspicion. The combination of indolent onset of symptoms, positive tuberculin skin test, and compatible radiographic findings, strongly suggests the diagnosis. TB, however, must be confirmed by positive culture or histologic proof. Prompt diagnosis and treatment are important to prevent serious bone and joint destruction.
