The inguinal region: anatomic differences in men and women with reference to hernia formation.

Fifty inguinal regions were dissected in anatomic human adult specimens, of which 26 were males and 24 females. The comparison of anatomic variations in both sexes showed that the distance between the public tubercle and the internal ring was larger, and the rectus muscle significantly wider in females. The diameter of the internal ring was larger in males, however, with significant variability. No differences were found regarding the presence or absence of the conjoint tendon. The anatomic variations may explain the sex differences in hernia formation.

Cytodiagnosis of soft tissue tumors.

The only acceptable definitive diagnosis of a soft tissue mass is histologic or cytologic examination. In recent years, fine-needle aspiration cytology is used in more and more centers for diagnosis of soft tissue masses. We studied 196 aspiration cytologies performed on soft tissue lesions. Out of these, in 48 cases a definitive surgical procedure or open biopsy for histology and further evaluation were performed. There were 25 sarcomas and 23 benign tumors. There was one false negative cytologic result in this group; no false positive cytologies were detected. It seems that cytodiagnosis of soft tissue masses performed by an experienced pathologist is the method of choice, permitting a good diagnostic evaluation, with almost none of the traumatic and oncologic disadvantages of the other methods of biopsy.

Fine needle aspiration cytology of the pancreas.

Fine needle aspiration cytology has been increasingly used in recent years to diagnose pancreatic lesions. During a 6 year period, we performed 33 aspiration cytologies of the pancreas. Twenty-one were performed during exploratory laparotomy, seven under the guidance of computed tomography and five guided by ultrasonography. In seven cases inflammatory lesions were found, while 26 cases were of malignant tumors. Out of these patients, 10 underwent additional tissue biopsy. The correlation between cytology and histology was 100%. We suggest that fine needle cytology of pancreatic and other intraabdominal lesions can be considered an accurate diagnostic procedure.

Varicocele in youth. A therapeutic dilemma.

The need for treatment of asymptomatic varicocele in youth is controversial. In the current study testicular volume and seminal variables were evaluated in three groups: young varicocele patients with undetermined fertility potential, infertile varicocele patients, and a control group of young males. The testicular volume was determined by ultrasonographic measurements. The results revealed a significant loss of "testicular mass" in both varicocele groups compared with the control group. The seminal findings disclosed a severe disturbance of spermatogenesis in the older varicocele group, whereas in the younger varicocele patients only the total spermatic count was significantly depressed. This difference in severity of functional impairment between the younger and older varicocele groups possibly points towards progressiveness of damage to the testicles. A more decisive therapeutic approach to the young male with asymptomatic varicocele and unknown fertility status could be justified.

Anatomical and computed tomographic studies of the pancreatic tail.

The location of the pancreatic tail in the lienorenal ligament and its relationship to the splenic hilus were studied in 32 computed tomography (CT) scannings and in 37 autopsy specimens. We found several anatomical variations in both study groups: the pancreatic tail did not penetrate the lienorenal ligament in 24% of the autopsy specimens and in 37.5% of the CT group. The tail was adjacent to the splenic hilus in 29.7% of the autopsies and in 25% of the CT group. We classified the anatomical variations into 4 categories, three of which could be well demonstrated on CT with satisfactory correlation to the anatomical findings of the autopsy specimens.

Frozen saphenous vein allografts for constructing vascular access for hemodialysis.

Frozen saphenous vein allografts were used in seven patients to construct vascular access for hemodialysis. In five patients the allografts connected the brachial artery to the axillary vein, and in two, the radial artery to the basilic vein. Five allografts functioned for periods varying from 6 to 20 months, one is still functioning after 3 years, and one graft occluded immediately following surgery. The availability of this biological material, the ease of its preparation, the very low cost, and the satisfactory graft survival, call for further evaluation of this method for complex vascular access problems in patients on chronic hemodialysis.

Emergency subtotal colectomy for obstructing carcinoma of the left colon.

Eight patients with obstructing carcinoma of the left colon underwent emergency subtotal colectomy and ileosigmoidostomy or ileoproctostomy. Based on the results obtained by us and those reported in the literature, it is our opinion that emergency subtotal colectomy with primary ileocolonic anastomosis should be considered as the procedure of choice for patients with obstructing carcinoma of the left colon.

Primary adenocarcinoma of the appendix: report of five cases and review of the literature.

Five patients with primary adenocarcinoma of the appendix are reported. All patients presented with symptoms resembling those of acute appendicitis or periappendicular abscess. In none of them was malignancy suspected prior to operation. It is advisable that every patient above 50 years of age presenting with symptoms of appendicitis undergo laparotomy, thus enabling a better exploration of the cecal region. If an appendiceal mass is present and frozen section shows malignancy, a right hemicolectomy should be performed. The prognosis of adenocarcinoma of the appendix is dismal as most patients present with an advanced stage of the disease.

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.

Sigmoid volvulus in adolescence.

Sigmoid volvulus in young adults is rare. It usually presents as chronic recurrent attacks of abdominal pain. The diagnosis is usually delayed because of a low level of suspicion. We present the case of a 17-year-old girl with recurrent episodes of sigmoid volvulus, to illustrate the problem.

Diagnosis of carcinoma of the breast by fine needle aspiration cytology.

During a six year period, 1,953 fine needle aspiration cytologies (FNAC) were performed for lumps of the breast. Of these, 355 were diagnosed as carcinoma of the breast. The FNAC was performed on an outpatient basis and the pathologic interpretation was available within 30 to 60 minutes. The treatment strategy was always guided by the clinical impression of the physician. If the results of a suspected mass were negative on FNAC, biopsy was performed and histologic study gave the final diagnosis. There were no false-positive results and only 6 per cent were false-negative findings diagnosed later by open biopsy. The over-all accuracy rate was 90 per cent plus 4 per cent diagnosed on cytologic examination as "suspicious" and which proved to be malignant. Based upon our accumulated results, simplicity of performing the test, its low cost, the extremely low morbidity, the immediate response and, above all, an over-all high accuracy rate, we conclude that FNAC is a highly recommended method for the diagnosis of carcinoma of the breast.
