Laparoscopic repair of paraumbilical ventral hernia with increasing size in an obese patient.

We report a case of paraumbilical ventral hernia with increasing size over 1 year which was successfully repaired using laparoscopic techniques. The repair was made using a 1-mm-thick expanded polytetrafluoroethylene patch inserted intraperitoneally and then stapled to the anterior abdominal wall over the defect. This laparoscopic repair is easily accessible, is considered to reduce morbidity and is thus recommended as the first choice of treatment for ventral hernia.

Eradication of large gastric varices by sclerotherapy combined with percutaneous transhepatic obliteration.

BACKGROUND/AIMS: The long-term results of a combination therapy of sclerotherapy with percutaneous transhepatic obliteration (PTO) was reviewed in 37 patients with large gastric varices. The study suggests that sclerotherapy combined with PTO can safely and effectively eradicate large gastric varices as an alternative approach to surgery. Complete eradication has also been shown to prevent the recurrence of gastric varices. MATERIAL AND METHODS: The long-term results of a combination therapy of sclerotherapy with PTO was reviewed in 37 patients with large gastric varices. RESULTS: Complete eradication of the gastric varices was obtained in 26 patients (70.3%). There was no recurrence of the varices in whom complete eradication had been obtained, but in 11 patients with incomplete eradication gastric varices recurred during the mean follow-up period of 37.5 months. Bleeding occurred in 4 after the treatment and one patient died of massive bleeding from the recurrent gastric varices. There were no major complications with the procedure except for one who had a peripheral pulmonary arterial embolization as a result of a steel coil used for the PTO. CONCLUSION: This study suggests that sclerotherapy combined with PTO can effectively and safely eradicate large gastric varices and is an alternative approach to surgery for treating patients with gastric varices. It is also shown that complete eradication leads to a prevention of recurrence of gastric varices.

Laparoscopic splenectomy with the newly devised morcellator.

BACKGROUND/AIMS: One of the major hurdles to overcome in the development of laparoscopic surgery has been finding effective extraction techniques for the removal of large tissue masses. The electromechanical morcellator makes it easy to remove relatively large sections of tissue from the abdomen through the existing incisions. To determine the safety and efficacy of the new morcellator in laparoscopic splenectomy, our preliminary experiences using the morcellator were reviewed and retrospectively compared with the results in patients who previously underwent conventional extraction techniques. METHODOLOGY: From February 1992 to March 1996, 31 patients underwent laparoscopic splenectomy. In the last eight patients, the new morcellator was used to remove the spleen, while in the remaining 23 patients, a laparoscopic splenectomy was performed using the conventional extraction techniques. RESULTS: In the last eight patients who underwent laparoscopic splenectomy, the newly devised morcellator was successfully used without any complications. The spleen could be removed from the abdominal cavity in an average of 15.9 +/- 10.4 minutes using the morcellator, while the average was 45.7 +/- 15.4 minutes using conventional techniques. It was not necessary to extend the skin incision in patients with the morcellator, while, on the other hand, a 2-cm extension of the existing skin incision was always required to remove the spleen in the latter method. CONCLUSION: The morcellator was found to be an effective device which can safely, efficiently and rapidly remove tissue masses. This procedure is therefore considered to be one feasible way to solve the age-old problem of intracorporeal morcellation.

Giant gastric varices after a left gastric venous caval shunt operation for esophageal varices: a case report.

A Japanese woman, who had undergone a left gastric venous caval shunt operation for esophageal varices 17 years earlier, was admitted to our hospital because of bleeding from giant gastric varices. An angiographic examination revealed a stealing of the portal blood flow to the inferior vena cava through both a dilated right gastroepiploic vein and a right gastric vein via the left gastric venous caval shunt. The gastric varices disappeared after obliterating both the feeding and drainage vessels by means of intervention radiology. We thus, consider the occlusion of both the afferent and efferent vessels to be an effective treatment for gastric varices.
