Anterior rectus sheath repair for inguinal hernia.

Fifty-four patients over the age of 40, with direct inguinal hernias were studied. Thirty-two of them underwent operation with the anterior rectus sheath flap, and 22 patients in whom the hernias were repaired by the method described by Bassini served as the control group. We could not demonstrate any significant difference between the two groups in regard to length of hospital stay, complications, and recurrence rate. There was only one recurrence in the rectus flap group. Anterior rectus sheath repair proved to be easy to perform and comfortable for the patient.

Diagnosis of varicocele and postoperative evaluation using inguinal ultrasonography.

Ultrasonographic real-time imaging and measurements of spermatic veins in the inguinal canal were evaluated in two groups of patients: 20 young men with varicocele and 18 controls. Examinations were performed with the patient in an upright relaxed position, and performing the Valsalva maneuver. The increase in diameter of the main vein during Valsalva maneuver was considered to quantitatively represent venous reflux. The data obtained were correlated with pre- and postoperative clinical findings. This method of evaluation proved to be a useful noninvasive diagnostic modality for detecting varicocele and for assessing treatment results. On the basis of venous diameters and reflux values, a classification of varicocele is proposed. Such an objective method of grading would eliminate the subjective impression and interpretation factors of the examiner.

The role of the spermatic cord layers in the development of varicoceles.

The theory that insufficiency of the spermatic cord layers could be the etiological factor in the development of varicocele is reviewed critically. A prospective study of 40 patients operated upon for a left indirect inguinal hernia was done. The spermatic cord layers were excised as a routine part of the operation but combined manual and Doppler examinations revealed no postoperative reflux into the pampiniform plexus. We conclude that the spermatic cord layers probably do not have a major role in the pathogenesis of varicocele.

Volvulus due to a tumor of Meckel's diverticulum.

Small-bowel obstruction in an old woman was the result of a twisted Meckel's diverticulum containing a large neoplasm. As neoplasms comprise only 1.2-1.4% of the complications of the diverticulum, and generally bleed or cause intussusception, we believe that the condition described is not common.

Varicocele and left renal vein compression.

Several current theories concerning the possible etiology of varicocele are critically reviewed. The possibility of arterial compression of the left renal vein, probably by the superior mesenteric artery is elaborated upon. Since direct experimentation is impossible because of the exclusively human character of this disease, a "triple indirect approach" is adopted. Three differently directed studies are conducted: intraoperative antegrade spermatic phlebography visualizing the left renal vein, anatomic dissection of the left renal vascular pedicle, and intraoperative marking of the superior mesenteric artery and the left renal vein for in vivo studies of their relationships. Because the outcomes of these three pathways converge and focus on the superior mesenteric artery compression of the left renal vein, it is concluded that this is a probable contributing mechanism in the etiology of varicocele.

Spermatic vein ligation in varicocele: prognosis and associated male and female infertility factors.

The fertility outcome of 129 spermatic vein ligations with good postoperative anatomic results is analyzed. For each couple, specific attention was also directed to other infertility factors. The study analyzes four groups: group I, 55 patients with varicocele only; group II, 16 patients with varicocele and prostatovesiculitis; group III, 16 patients with varicocele and a severe degree of testicular failure; and group IV, 42 patients with a varicocele only and associated female infertility factors. In each group, the pregnancy rate within 6 to 24 months after the operation was recorded. The control subjects were 36 patients with varicocele only who had declined or postponed intervention for 6 months. The best results were obtained in group I. Sperm motility improved following ligation and was associated with a greater percentage of pregnancies within a shorter period: 51% and 62% within 6 and 12 months, respectively, as compared with the control group (14% within 6 months). The prostatic disease required additional treatment for a longer period, but results similar to those of group I were eventually obtained (50% pregnancy rate). With testicular failure or female infertility factors, the prognosis worsened (31% overall pregnancy rate).
