Anterior sacroiliac fusion: a new video-assisted endoscopic technique.

We present a case of sacroiliac fusion performed for an intraarticular osteochondroma of the sacroiliac joint, which was the cause of severe pain and disability. Excision of the lesion and sacroiliac fusion were successfully performed by utilizing minimally invasive surgical techniques. Although the application of this technique requires a dedicated and highly experienced team, the encouraging result of our first case, with minimal morbidity and disability due to the operation, induces us to recommend this technique in sacroiliac fusion, especially when fusion is combined with additional procedures such as drainage, biopsy, or excision.

Mirizzi syndrome: choice of surgical procedure in the laparoscopic era.

Impaction of a calculus in gallbladder neck or cystic duct or even in its remnant may produce common hepatic duct stricture by direct mechanical impression or associated inflammation. This clinical entity is referred to as Mirizzi syndrome. Four patients were operated on for Mirizzi syndrome. This represents 0.9% of the 444 patients who underwent laparoscopic cholecystectomy in our clinic. Two cases with Mirizzi syndrome type I, one of which had a stone in a gallbladder remnant, were successfully treated by laparoscopic cholecystectomy without any complications. One patient developed a bile leakage; fistulography via a sump drain revealed bile leakage from the laceration site of the stone, and the patient was reoperated on to perform a Roux-en-Y hepaticojejunostomy. The patient was lost due to cardiopulmonary arrest originating from septic shock. In another case diagnosed as Mirizzi type II, the operation was converted to an open procedure due to intense inflammation and fibrosis around the area of the Calot's triangle. Subtotal cholecystectomy was done and the defect on the common hepatic duct repaired by means of a gallbladder flap over the T tube.

Laser-welded ureteral anastomoses: experimental studies with three techniques.

Tissue welding with laser energy is a new technique for reconstructive surgery. The potential advantages of laser welding are (a) lack of foreign body reaction, (b) decreased operative time, (c) less tissue manipulation, and (d) effective union of tissues equivalent to sutured anastomoses. We have performed ureteral anastomoses in adult mongrel dogs using a KTP 532 nm laser at an intensity of 1.4 W. Multiple "spot welds" of 1-s duration were utilized in a single layer anastomosis. Laser-welded anastomoses were performed with and without protein solder (33% and 50% human albumin) and were compared to sutured anastomoses. The laser-welded anastomoses required less operative time and provided bursting pressure levels similar to those of traditional sutured anastomoses. There was no advantage or disadvantage to the addition of human albumin as a solder in these experimental studies.

Persistent peripheral nerve pathologies in patients with electric burns.

Clinical and electrodiagnostic evaluations were performed in 25 patients with electric burns who were injured 2 to 13 years before the study. Abnormal motor nerve conduct findings were detected in 12 of the patients. In nine patients, abnormalities were observed in more than one nerve. There was a positive relation noted between age and nerve lesions. Weakness was the most prominent clinical finding.

Laparoscopic removal of a gallbladder remnant.

We describe a patient who had an incomplete open cholecystectomy 32 years previously and was hospitalized with jaundice due to a stone in the gallbladder remnant encroaching on the common bile duct. Despite extensive adhesions the gallbladder remnant was removed with laparoscopic techniques and the patient had an uneventful recovery. We conclude that previous surgery, even on the gallbladder, does not preclude the successful completion of a laparoscopic cholecystectomy.
