Is testicular perfusion influenced during laparoscopic inguinal hernia surgery?

BACKGROUND: The influence of laparoscopic inguinal hernia surgery is still unclear. The aim of this study was to compare the possible early effects of laparoscopic and open inguinal hernia repair on testicular perfusion. METHODS: In this prospective trial, 44 patients underwent mesh repair of a primary inguinal hernia assigned to one of two procedures: open anterior mesh repair (n = 29) or a laparoscopic totally extraperitoneal approach (n = 15). Doppler ultrasound was used to determine the hemodynamic characteristics of the testicular blood flow. RESULTS: No statistically significant differences were found between the two groups in terms of Doppler flow parameters for the preoperative, very early (day 1), and early postoperative (day 7) periods. When Doppler flow parameters of the testicular artery were compared in the conventional group, statistically significant differences were found between preoperative and very early postoperative values (p < 0.05). Meanwhile, comparison among flow parameters of the testicular, capsular, and intratesticular arteries of the laparoscopic group showed statistically significant differences between preoperative and very early postoperative and between preoperative and early postoperative values (p < 0.05). There were no statistically differences in postoperative complications between the two groups. CONCLUSION: Testicular blood flow is influenced during laparoscopic inguinal hernia surgery. Whether changes in flow parameters remain in the late postoperative period, and whether they have an impact on complications will be evaluated in further studies.

Variations of hepatic veins: helical computerized tomography experience in 100 consecutive living liver donors with emphasis on right lobe.

Anatomical variations in the venous system of liver are not a rarity. A prospective helical computerized tomography (CT) study was undertaken to determine the prevalence of surgically significant hepatic venous anatomic variations among 100 consecutive living liver donors. The studies evaluated the ramification pattern of hepatic veins, the presence of accessory hepatic veins, and of segment 5 or 8 veins (or both) draining into middle hepatic vein. These data obtained by CT influenced surgical planning. Sixty-four donors donated their right lobes and 24 donors, left lateral segments. Only one donor candidate was refused due to combined hepatic and portal venous variations accompanied by multiple bile ducts. Eleven donors were also refused due to reasons other than anatomical variations. Seventeen segment 5 and 17 segment 8 veins draining into middle hepatic vein were anastomosed to inferior vena cava in 23 (36%) of the right lobe liver transplantations. The middle hepatic vein was harvested in only one of the donors. Among the 100 cases, 47 had accessory right inferior hepatic veins, 13 of which were multiple. Twenty-two of the right lobe grafts required surgical anastomoses of these accessory hepatic veins (34%). An isolated hepatic vein anomaly or the presence of accessory hepatic veins are not contraindications to be a living liver donor candidate. However, preoperative knowledge of vascular variations alters surgical management. Helical CT is a valuable tool to delineate the hepatic venous anatomy for surgical planning in living liver donors.

Roux-en-Y bleeding after living donor liver transplantation: a novel technique for surgical treatment.

Upper gastrointestinal bleeding (GIB) is one of the most common gastroenterologic complications following liver transplantation. The aim of this study is to define the prevalence of GIB due to Roux- en Y (R-Y) enteral anastomoses after living donor liver transplantation (LDLT) and recommend an anastomotic technique for easy surgical intervention. Ninety-five patients underwent 96 LDLT from June 1999 through January 2003. R-Y biliary reconstruction was employed in 43 patients. Anastomoses were end-to-side (ES) in the first 25 patients and side-to-side (SS) type in the last 18 patients. GIB occurred in 13 patients (30%). The R-Y anastomotic line was shown to be the bleeding site in 10 patients. Anastomoses were in ES fashion in 7 of 10 patients (70%). In other words 28% of ES and 17% of SS anastomoses displayed a bleeding episode after LDLT. Four patients required surgical intervention (Three ES, one SS), namely an operative rate of 9%. The type of the jejunojejunostomy, the UNOS or Child-Pugh scores, the presence of preexisting portal hypertension, the duration of portal vein clamping, the GRWR of patients, revealed no statistical significant difference between bleeding and non- bleeding patients. Although statistical analyses did not reveal any significant difference (P =.47), GIB was higher among patients with an ES type of anastomoses. As a result we recommend a jejunojejunostomy in SS fashion on the antimesenteric borders of the jejunal segments with a 3-4 cm blind intestinal segment. The surgical procedure for R-Y bleeding may then be performed without disrupting the jejunojejunostomy.

Completion thyroidectomy for thyroid cancer.

BACKGROUND: Whether thyroid re-operations are associated with an increased complication risk is controversial. The aim of this study was to perform a retrospective analysis of patients undergoing re-operative surgery of the thyroid. We analyzed the safety and the impact of delay on complications before undertaking radicalization thyroidectomy. MATERIAL AND METHODS: From January 1996 to July 2002, 150 consecutive patients with thyroid cancer were treated in our institution. A total of 62 patients underwent completion thyroidectomy. Twenty-seven had undergone their initial operation in our centre. Medical and pathologic data were obtained retropectively. RESULTS: Pathological examination of the specimen after completion surgery revealed malignancy in a total of 35% of 62 patients. The time interval between initial surgery and completion thyroidectomy ranged from 5 days to 24 months (mean 3.1 months). Complications after re-operation were transient recurrent nerve injury in 1.6%, transient hypoparathyroidism in 4.8%, permanent hypoparathyroidism in 1.6% and chylous discharge in 1.6% of the patients. There was no significant difference between complication rates in patients operated on within 90 days or those operated on after this period (p > 0.05). CONCLUSIONS: This study suggests that completion thyroidectomy is safe in the hands of experienced endocrine surgeons and the timing of re-operation has no impact on the development of complications.
