Mucinous Epithelium in Endometrial Curetting Leading to Diagnostic Conundrum: A Case Report.

Mucinous differentiation of the endometrium can occur in a spectrum of changes ranging from benign (metaplasia) to malignant (adenocarcinomas with mucinous differentiation). A rarer differential which is usually not considered is a teratoma. We present a case of a 55-yr-old woman with history of irregular perimenopausal bleeding. Endometrial curetting revealed proliferative mucinous epithelium on histology raising a possibility of low-grade epithelial mucinous malignancy. Hysterectomy was performed and histologic examination revealed a diagnosis of uterine mature teratoma. Mature cystic teratoma of the lower uterine segment is very rare and presence of just one element such as mucinous epithelium can lead to a misdiagnosis of carcinoma on biopsy or curetting.

A safe, effective, and cheap method of achieving pancreatic rest in patients with chronic pancreatitis with refractory symptoms and malnutrition.

OBJECTIVES: Chronic pancreatitis (CP) is common. It is associated with a substantial morbidity, including malnutrition, malabsorption, pseudocysts, metabolic disturbances, and intractable abdominal pain. Approximately 5% of patients with CP are refractory to nutritional support and opiate analgesia, making management challenging.Pancreatic rest can provide symptomatic relief. However, achieving simultaneous pancreatic rest and adequate nutritional support in these patients is difficult. We describe a technique for providing nutritional support and pancreatic rest in patients with intractable symptomatic CP. METHODS: Three patients with symptomatic CP refractory to standard treatment were included in the study. All 3 patients had masses associated with the pancreas. Symptom relief and adequate nutritional support were achieved by inserting a long-term nasojejunal (NJ) tube (Flocare Bengmark, Nutricia Clinical Care, United Kingdom) under ambulatory endoscopic guidance. Data were recorded prospectively. RESULTS: Long-term NJ tube feeding achieved pancreatic rest and significant symptomatic relief while delivering adequate nutritional support. Pseudocyst size decreased substantially in 2 patients. The third patient was found to have pancreatic carcinoma after pancreaticoduodenectomy. CONCLUSIONS: In patients with symptomatic CP refractory to standard nutritional support and opiate analgesia, long-term NJ tube feeding can be a cheap, well-tolerated, safe, and effective method of providing adequate nutritional support and substantially relieving intractable symptoms.

Pelvic vein embolisation in the management of varicose veins.

Pelvic vein incompetence is common in patients with atypical varicose veins, contributing to their recurrence after surgery. Therefore, refluxing pelvic veins should be identified and treated. We present our experience with pelvic vein embolisation in patients presenting with varicose veins. Patients presenting with varicose veins with a duplex-proven contribution from perivulval veins undergo transvaginal duplex sonography (TVUS) to identify refluxing pelvic veins. Those with positive scans undergo embolisation before surgical treatment of their lower limb varicose veins. A total of 218 women (mean age of 46.3 years) were treated. Parity was documented in the first 60 patients, of whom 47 (78.3%) were multiparous, 11 (18.3%) had had one previous pregnancy, and 2 (3.3%) were nulliparous. The left ovarian vein was embolised in 78%, the right internal iliac in 64.7%, the left internal iliac in 56.4%, and the right ovarian vein in 42.2% of patients. At follow-up TVUS, mild reflux only was seen in 16, marked persistent reflux in 6, and new reflux in 3 patients. These 9 women underwent successful repeat embolisation. Two patients experienced pulmonary embolisation of the coils, of whom 1 was asymptomatic and 1 was successfully retrieved; 1 patient had a misplaced coil protruding into the common femoral vein; and 1 patient had perineal thrombophlebitis. The results of our study showed that pelvic venous embolisation by way of a transjugular approach is a safe and effective technique in the treatment of pelvic vein reflux.

Percutaneous nephrostomy of nondilated renal collecting systems with fluoroscopic guidance: technique and results.

PURPOSE: To retrospectively review experience with a double-puncture technique for percutaneous nephrostomy of nondilated renal collecting systems. MATERIALS AND METHODS: Over a 5-year period, 15 patients (26 kidneys) without calyceal dilatation at ultrasonography (US) who required nephrostomy drainage were studied. Eleven patients (21 kidneys) had ureteral leaks or fistulas, one patient (one kidney) had a renal pelvic stone, one patient (one kidney) was suspected of having a ureteral tumor, and the final two patients (three kidneys) had acute nondilated renal failure. Mean age was 62 years (range, 20-78 years); 13 patients were men and two were women. A double-puncture technique was used with fluoroscopic guidance (supplemented with US in some patients who had renal failure). After intravenous administration of iodinated contrast material, a 22-gauge needle was inserted into the opacified renal pelvis, and double-contrast pyelography was performed by using air or carbon dioxide to allow visualization and distention of the nondependent calyces for definitive renal access with an 18-gauge 5-F sheath-needle set and a hydrophilic wire. After serial dilation, a nephrostomy or nephroureteral catheter was inserted. Success and major complication rates were studied by reviewing radiologic and clinical case notes. RESULTS: Catheter placement was successful in 25 (96%) of 26 kidneys after one, two, or three passes with the sheath-needle set. In all successful cases, the calyx was accurately punctured. There were two major complications. One patient developed hematuria that required transfusion but no further intervention; another sustained a renal pelvic injury, but this was believed to be due to excessive dilation of the pelviureteral junction, not faulty renal puncture. There were no cases of septicemia. CONCLUSION: With a double-puncture technique and air or carbon dioxide distention, nephrostomy was achieved in 25 (96%) of all nondilated renal collecting systems. There were two major complications (two [8%] of 25 kidneys, two [13%] of 15 patients), but only one was secondary to the renal puncture.

Peritoneovenous shunt insertion for intractable ascites: a district general hospital experience.

Ascites often contributes to patient morbidity and discomfort. When refractory to medical management, it has been managed with repeated paracentesis, implantable ports for drainage, or diversion to the urinary bladder. Peritoneovenous shunt insertion has been a technique that was traditionally performed only by surgeons but is now within the realm of interventional radiologists. Its advantage is that protein-rich ascitic fluid is returned to the intravascular compartment. This retrospective study elaborates on the successes and problems encountered during shunt insertion in our first 13 patients. Two patients are well with a functioning shunt at 14 and 32 weeks. In 6 the shunt functioned until the patients' death from the underlying malignancy. Two required revision with variable success and in 2, shunt function could not be salvaged. There was one procedure-related mortality. Radiological insertion of these shunts is feasible and should be considered for selected patients. Options are available for assessment and salvaging of dysfunctional shunts.
