[Endoscopic management of biliary fistula].

From January 1991 to July 1993 we diagnosed 16 patients with biliary fistulas. Nine patients showed a fistula of the stump after cholecystectomy (two laparoscopic and the rest in a conventional form). In none was there any evidence of residual stones. Three patients that showed biliary fistula who had residual stones which was no diagnosed during surgery. Four patients had biliary fistulas at different levels after abdominal traumas due to bullet wounds. All the patients were treated endoscopically by means of endoscopic sphincterotomy and in one of them it was necessary to place a biliary stent due to the fact that there was a stricture under the level of the fistula. One patient who, in addition to the fistula had an abscess was drained guided by ultrasound after the sphincterotomy. The evolution of the patients was satisfactory. There were no complications because of the procedure.

[Colitis due to radiation: endoscopic management with heat probe].

Rectal bleeding is a frequent symptom in radiation colitis, and is due to vascular lesions usually confined to the rectum. We present our preliminary experience with the use of the heater probe, in eight patients with radiation proctitis, whose main symptom was rectal bleeding. Six patients had radiation for carcinoma of the cervix and 2 had endometrial cancer. One to four sessions of coagulation were performed with an intensity of 200 to 400 Joules per session. In all patients a good response was obtained, bleeding diminished or stopped completely, with improvement of blood counts and the need for transfusions. We think that heater probe is a good therapeutic alternative, for the management of these difficult complication.

[Percutaneous endoscopic gastrostomy in patients with head and neck neoplasms. Evaluation of a new gastrostomy].

Since their aparition in 1980, percutaneus endoscopic gastrostomy (PEG), represented a dramatic impact in the enteral nutrition thecnics and their indication have expanded. The PEG have many advantages over the surgical gastrostomy. In this paper, we present our experience with the use of PEG in patients with head and neck cancer using a new home made gastrostome. Included were 61 patients 37 males (64.8%), 21 females (36.2%) with ages betwen 11 and 72 years. In 3 patients the PEG was not intended because tight esophageal stenoses. The PEG was completed in 56 cases (91.8%). In 5 patients (8.6%) there were minor complications (4 infections and 1 patient with pain). We have only one case of major complication which consisted in migration of gastrotome to the abdominal wall (Buried Bumper Syndrome). The gastrostome was patent between 15 and 312 days with a median of 125 days. The gastrostomies was made with siliconed 22Fr Foley catheter, crazy glue, and plastic tops. The Foley catheter is acid resistant and not deteriorate like other materials like latex. There was not adverse reaction at the ostomy site. The cost of the kit is about 11 US$ and the commercial kit is 125 US$, on the other hand the internal diameter is 15% wider than the commercial one.
