Parameters of Doppler ultrasound at five days posttransplantation as predictors of histology and renal function at one year.

Introduction: In our center, a Doppler ultrasound (DU) is performed at 5 days after transplantation. The normal upper limit of flow velocity (FV) in the renal artery is 200-250 cm/s. The resistance index (RI) is considered elevated when >0.

Pancreatic insulinoma: a surgical experience.

Background: Small size, high benignity rate, and sporadic nature make insulinomas suitable for laparoscopic resection. On the other hand, occult location or multicentricity mandate open surgery. This study was designed to analyze a series of patients who had pancreatic insulinomas and underwent initial treatment at our institution.

Malignant insulinoma arising from intrasplenic heterotopic pancreas.

Context: Heterotopic pancreas is defined as ectopic pancreatic tissue without vascular or anatomic continuity with the normal pancreas. The spleen is a rare site of origin. This case report describes a patient with a malignant insulinoma which originated from an intrasplenic heterotopic pancreas.

Laparoscopic drainage of pancreatic pseudocysts.

Background: Laparoscopic drainage of pancreatic pseudocysts (PPs) has been used in selected cases. The aim of this study is to analyze our results with the laparoscopic technique and to compare them with those of a cohort of patients treated by open surgery during the same time period.

Patients And Methods: Ten patients underwent laparoscopic drainage of PPs during a 7-year period [laparoscopic group (LG)].

Correlation between radiologic and pathologic dimensions of adrenal masses.

The size of adrenal tumors has been shown to be a good predictor of malignancy. There is still some controversy about the concordance between radiologic and real pathologic measurements. The aim of this study is to determine the correlation between direct and corrected radiologic computed tomography scan dimensions and the measurements of the resected specimen.

[Renal artery stenosis after transplantation: treatment using percutaneous transluminal angioplasty and placement of an expandable metal luminal prosthesis].

Unlabelled: Transplant renal artery stenosis (TRAS) is a cause of severe post transplant hypertension with a widely variable reported incidence from 1 to 25%. We herein report 3 cases of endoluminal stent placement after percutaneous transluminal angioplasty for treatment of TRAS. Clinical and laboratory findings during their follow-up, suggestive of TRAS included: elevated mean blood pressure, bruit over the graft area(2/3), and increase in serum creatinine (2/3).

Asymptomatic gallstones and duration of cyclosporine use in kidney transplant recipients.

Background: Cyclosporine (CsA) use has been associated to the development of cholelithiasis in transplant recipients. We herein explored the role of time under CsA on this association in asymptomatic adult kidney transplant recipients (KTR).

Methods: A cross-sectional study was conducted in 140 KTR with variable post-transplant follow-up (PTFU), and without history of symptomatic biliary disease.

[Retrorectal tumors].

Objectives: To analyze the clinical presentation, and diagnostic and therapeutic implications in patients with retro-rectal tumors.

Methods: This paper reports two patients. Both patients had constipation and change in bowel habits, and the physical examination revealed the retro-rectal neoplasia.

[Four cases of parathyroid cancer].

Parathyroid carcinoma is a rare cause of primary hyperparathyroidism with a prevalence ranging between 0.5 and 4%. Because of their aggressiveness, prompt diagnosis and treatment are mandatory.

[Laparoscopic splenectomy in autoimmune thrombocytopenic purpura].

Objective: To describe the perioperative characteristics, complications and outcome of the first 22 patients who underwent laparoscopic splenectomy for refractary/recurrent ITP in our institution.

Material And Methods: Clinical and biochemical characteristics, spleen size, indication for surgery, operative time, blood requirements, complications and outcome of 22 patients who underwent laparoscopic splenectomy between 1994 and 1997 were prospectively recorded. Their mean age was 40 +/- 15 (+/- SD), 15 females and 7 males.

Case report of primary squamous carcinoma of the rectum.

Purpose: To report a patient with primary squamous carcinoma of the rectum.

Case Report: A 40-year-old woman with hematochezia and change in bowel habits was studied. The main laboratory finding was a mild anemia.

[Mucocele of the vermiform appendix].

Background: Mucocele is a cystic dilatation of the vermiform appendix that contains mucous material. It may be caused by benign or malignant diseases.

Aim: To report and discuss four cases with mucocele.
