Diagnostic and therapeutic laparoscopy for nonpalpable testis.

BACKGROUND: We evaluated the use of laparoscopy in the management of impalpable testis to determine what advantages it might offer over the open approach. METHODS: Over a 5.5-year period, a total of 46 patients with 53 nonpalpable testes underwent a laparoscopic procedure at our hospital. There were 28 cases of intraabdominal testis (52.83%), 18 cases of the vas and vessels entering the internal ring (33.96%), and seven cases of intraabdominally absent testis (13.20%). We performed a laparoscopic orchiopexy for 24 testes (scrotal in 21 cases and partial to the inguinal canal in three cases) and an orchiectomy for three testes. We encountered inguinal hernia in 14 cases (26.41%). RESULTS: At follow-up, all testes were the same size as at the time of operation and were well positioned in the scrotum, except for four testes that required reoperation due to partial migration at the superficial inguinal ring. The operating time was <1 h in unilateral cases and <2 h for the bilateral cases. All procedures were completed successfully without conversion or complications. CONCLUSIONS: Laparoscopy is the only exploratory procedure that is accurate enough to enable the diagnosis of nonpalpable testis and also allow the surgical treatment to be done in the same setting.

[Indications of transduodenal papillotomy for choledochal cyst].

UNLABELLED: The Choledochal Cyst is a dilatation of the biliary tract whose etiology is still under debate. OBJECTIVE: This paper analyzes the cases of our group an contributes on the indications of transduodenal papilotomy in the surgical treatment of this process. MATERIAL AND METHODS: Seven cases diagnosed as choledochal cysts are presented with mean age between 3 and 10 years (5 females and 2 males). Six cases were presented with abdominal pain, four with jaundice, three presented with biliary stones and one cases was a casual discovery during an US examination. In all cases US and magnetic resonance cholangiopancreatography (MRCP) were performed as preoperative work-up. In one case an endoscopic retrograde cholangiopancreatography (ERCP) was made. In all cases intraoperative cholangiography was carried out. The surgical treatment was quistectomy and hepatico yeyunostomy Roux-Y in four cases; in one of them a transduodenal papilotomy was added. Cholecystectomy and transduodenal papilotomy was made in three cases, two of them presented choledocholithiasys. RESULTS: All patients are symptoms free after a mean follow up period of 2 years and 3 months (range: 1 year and 6 months to 4 years and 10 months). In one case persists dilated choledochal distal stump on MRCP.

[Epidermoid cyst of the mouth floor].

The epidermoid cysts are frequent during childhood, however mouth floor location are very unusual, because of their more difficult diagnosis and therapeutic approach. We present a 5 years old male, symptoms free until a week before, when his parents noticed a well defined mass in the mouth floor. A physical examination leaded to the diagnosis of possible epidermoid cyst. The tumor was excised through an introral approach. A review of different diagnostic means and surgical management are undertaken.

Hepatic artery aneurysm in a child.

The present report refers to a child hospitalized because of nonspecific symptomatology, who was found to have aneurysms of both hepatic arteries. A year after simple proximal ligature of both hepatic arteries, the child remains symptom-free and developing normally. Proximal ligation appears to be a simple and effective technique for treating hepatic artery aneurysm in children in preference to direct approach of the vascular pathology.

[Endoscopy-assisted renovascular surgery].

OBJECTIVES: Laparoscopic surgery still has many impediments which render it impracticable or very difficult in many cases. In this article we describe in the laboratory the possibilities of performing it helped with a hand that has previously been introduced in the abdomen through a minilaparotomy. METHODS: Once the animal is in the lateral decubitus position, a longitudinal suprapubic incision of some 5 cm is done, through which the surgeons left hand is introduced. Then, together with the instruments, the kidney, its vessels, the aorta and vena cava are dissected. In one case the left renal artery was temporally clamped, divided and then sutured. RESULTS: This minimally invasive technique allowed in all the cases to accurately perform the operation in a very short time and with minimal risk. CONCLUSIONS: The main indication of this technique are the cases in which a large incision is required, as in large renal tumors or testicular cancer surgery. It is particularly useful in previously operated patients, or if a complication arises during a laparoscopy, or if a minilaparotomy is required as, in ileal conduits. This procedure also opens the door to a new approach to renovascular surgery.
