Vasovasostomy--a 15-year experience.

OBJECTIVE: This study aimed to evaluate the results of vasovasostomies performed in the authors' clinic over 15 years. MATERIAL AND METHODS: Between 1983 and 1998 39 vasovasostomies were performed using a macroscopic technique. The medical charts were reviewed and a postal survey was sent to 36 of these patients. The patients were invited to visit the outpatient department and to give semen for analysis and a blood sample for determination of serum antisperm antibodies and serum follicle-stimulating hormone. Twenty-five patients filled in the questionnaire and 10 patients were obtained for further semen and serum analyses. RESULTS: The overall pregnancy rate was 56% (14/25 respondents). Three of these 14 men used an assisted reproduction method with their own ejaculated sperm. The postoperative patency was recorded in the medical charts only sporadically. The age and the interval between the vasectomy and vasectomy reversal averaged 42 years and 8.6 years, respectively. Those men who could father a child had a somewhat shorter mean obstructive interval than those who failed (8.0 vs 9.3 years), although the difference was not statistically significant in this small patient sample. The serum follicle-stimulating hormone concentrations were normal, with no association with the pregnancy rate. CONCLUSION: Macroscopic vasovasostomy is an effective means of re-establishing fertility in vasectomized men.

Accidental injuries of the hepatoduodenal ligament.

OBJECTIVE: To report our experience in the management of accidental injuries to the structures of the hepatoduodenal ligament. DESIGN: Retrospective study of medical records. SETTING: University department of surgery. SUBJECTS: 8 patients admitted after accidents (road traffic accidents, n = 4; falls, n = 2; and gunshot and stab wounds, n = 1 each) who were found at laparotomy to have injuries of the structures of the hepatoduodenal ligament. INTERVENTIONS: Laparotomy in all cases. MAIN OUTCOME MEASURES: Morbidity and mortality. RESULTS: One patient died (13%) of multiple organ failure after a gunshot wound of the portal vein, liver, inferior vena cava, right renal artery, and right kidney. All patients had associated injuries. There were 3 complete transsections of the common bile duct, two of which were treated by Roux-en-Y cholecystojejunostomy and one by choledochojejunostomy over a T tube. Two lacerations of the common hepatic duct were treated by T tube choledochostomy. All injuries to blood vessels were sutured. Only one patient survived without any complications, and two developed cholangitis after cholecystojejunostomy that required further operation 5 and 16 months after the initial operation. CONCLUSIONS: Blunt injuries to the hepatoduodenal ligament are easily overlooked, leading to delayed morbidity. Complete transsections of the bile duct are best managed by choledochojejunostomy with a Roux-en-Y loop; T tube choledochostomy is usually sufficient when treating small partial lesions of lobar bile ducts; and most non-circumferential vascular lesions are best treated by suture.
