Aim: The aim of the study was to present the incidence of early and late surgical complications in a group of patients treated with anterior approach for spine lesions. The study was also focused on technical aspects for lesions of D1-D2 and L5-S1 segments and results on a group of patients underwent adjunctive surgical procedures at the same time of spinal surgery., Methods: This was a retrospective study based on our database from April 1998 to December 2008. The study enrolled 120 consecutive patients (M/F 73/47; mean age 43.1 years; range 15-70 years) who underwent spinal surgery for trauma (92 patients), primitive or metastatic cancer (12 patients), benign lesion (2 patients), degenerative disc disease (6 patients) and infection disease (8 patients). This work describes the anterior approach to the spine., Results: No death was recorded. Thirty-two patients (26.6%) presented postoperative complications: persistent urinary tract infections in 19 (15.9%), pneumonia in 6 (5%), pleural effusion in 3 (2.5%), wound infection in 2 (1.6%), retro-peritoneal abscess in 1 (0.8%) and haemorrhage in 1 (0.8%). During the follow-up (mean 3.8 years; range 2 months-10 years) 1 patient (0.8%) required two further surgical procedures for tuberculosis abscess recurrences., Conclusion: Anterior approach to the spine is effective and safe. Surgical complications do not negatively affect patient survival and spine stabilization included patients with D1-D2 and L5-S1 lesion and patients who receive adjunctive surgery at the same time of spine procedure.

Background: Combined heart-kidney transplantation (HKTx) is an accepted therapeutic option for patients with end-stage heart disease associated with severely impaired renal function. We report our long-term follow-up with this combined procedure., Patients and Methods: Between April 1989 to November 2009, nine patients underwent combined simultaneous (HKTx) at our center. Seven patients were males (mean age 45.2 +/- 10.12 years); seven patients were on dialysis at the time of transplantation., Results: Surgical procedures were uneventful in all patients. One patient died in the intensive care unit 41 days after transplantation. During long-term follow-up, three patients died: one due to infection and multiorgan failure 148 months after HKTx, one due to a lung neoplasm after 6 years, and one, a cerebral stroke at 34 months after transplantation. Only one patient experience renal allograft failure secondary to hypertension and cyclosporine nephrotoxicity at 10 years after HKTx with the need for renal replacement therapy. Last estimated glomerular filtration rates of all other patients was 61.3 +/- 17.4 mL/min., Conclusions: In selected patients, with coexisting end-stage cardiac and renal failure, combined HKTx with an allograft from the same donor proved to give satisfactory short- and long-term results, with a low incidence of both cardiac and renal allograft complications., (Copyright (c) 2010 Elsevier Inc.

To satisfy the increasing requests for renal grafts, elderly donors are increasingly accepted for kidney transplant at many centers. The main unresolved question is the long-term effect on graft survival of potential histological lesions due to donor age. We present a prospective histological study performed from January 1997 to December 2001 on 184 consecutively transplanted renal grafts in which the only criterion for graft acceptance was a normal value of serum creatinine upon admission to the intensive care unit independent of donor age. At the end of the study, 57 recipients (31%) of mean age 55 years (range 39 to 67 years) received a renal graft from donors aged more than 60 years (mean age 66 years; range 60 to 75 years), this cohort denoted as older donor kidney transplant group (ODKTG) and 127 recipients (69%) with a mean age of 49 years (range 21 to 63 years) received a renal graft from donors whose age was lower than 60 years (mean age 49 years; range 16 to 59 years), a cohort denoted as the younger donor kidney transplant group (YDKTG). The two groups were comparable for time of dialysis, cold ischemia time, immunosuppression therapy, grading of histological damage. At the end of the study with a mean follow-up of 5.6 years (range 3.5 to 7.5 years), primary graft nonfunction and delayed graft function were significantly more represented in the ODKTG than the YDKTG. Cumulative patient and graft survival was 84.3% and 79.4% in the ODKTG, respectively, and 93.8% and 85.9% in the YDKTG, respectively (P = NS). Cumulative serum creatinine values were 1.98 mg/100 mL in ODKTG and 1.65 mg/100 mL in YDKTG (P = NS). In conclusion, renal grafts from older donors presented histological damage comparable to that seen among renal grafts from younger donors.

Maxillofacial fractures are uncommon in the pediatric population, and their treatment is unique due to the psychological, physiological, developmental and anatomical characteristics of children. We present the case of a boy who was treated in an outpatient dental clinic using a lingual splint for the reduction, stabilization and fixation of a mandibular body fracture. This technique is a reliable, noninvasive procedure that dentists may consider in selected cases by referral to an oral and maxillofacial surgeon. It also limits the discomfort and morbidity that can be associated with maxillomandibular fixation or open reduction and internal fixation in pediatric patients.

Living donation in the field of renal transplantation has increased over time as well as the use of laparoscopic nephrectomy. We present a 15-year experience on 162 living donors (105 women, 57 men; mean age, 46.7 years; range, 31-74 years) who underwent nephrectomy using different surgical approaches as open lombotomic nephrectomy (OLN), open transperitoneal nephrectomy (OTN), and laparoscopic hand-assisted nephrectomy (LHAN). We collected data on residual donor and recipient renal function, as well as early versus late medical and surgical complications. With a mean follow-up of about 8 years, we observed normal residual renal function in all donors and similar results of early and late graft function independent of the surgical procedure. Long-term incidence of hypertension and noninsulin-dependent diabetes in living donors was similar to the general population. OLN and OTN donors showed higher incidences of early and late complications, readmissions, and reoperations than LHAN donors. Our results confirmed that living donor nephrectomy is a safe procedure without serious side effects in terms of renal function and long-term quality of life. LHAN should be the preferred technique because of a lower incidence of early and late complications.

Surgical complications are the leading cause of pancreatic graft loss among diabetic patients who undergo pancreas transplantation alone (PTA), or combined with kidney transplantations (PK) or after kidney transplantations (PAK). Therapeutic effects on secondary complications of diabetes justify pancreas retransplantation (re-PT) when the first graft is lost. However, the appropriate timing for retransplant and related problems is not known. We present our initial experience on re-PT performed on seven diabetic patients who lost their first pancreas grafts (PK) due to surgical complications (venous thrombosis in five and enteric fistula in two). Five re-PT were performed a few days after the first PT without a second course of induction therapy, while two patients received re-PT some months later with reinduction therapy. In the early re-PT group, one patient died some hours after the second surgical procedure due to pulmonary embolism, while four patients lost their second grafts due to accelerated rejection within 2 years from re-PT. In the late re-PT group, both patients have good graft function without signs of rejection. Our initial experience showed discouraging results in the group of early re-PT, due to accelerated rejection episodes leading to a high incidence of graft loss. Late re-PT accompanied by reinduction therapy seemed to have better results.

We examined surgical complications among a group of diabetic type 1 patients (IDDM) with end-stage renal disease (ESRD) who had undergone pancreas-kidney transplantations (PK). Between October 1993 and August 2004, 70 SPK were performed using bladder (n = 14) or enteric (n = 56) drainage. Donors were selected according to standard criteria (mean age, 27.6 years; range, 17-49). All patients received cyclosporine-based immunosuppression. All pancreata functioned immediately, whereas 2 patients needed postoperative dialysis. Four patients (5.7%) lost their pancreatic graft due to vascular thrombosis; both patients underwent urgent allograft pancreaectomy and pancreas retransplantation (re-PT). One of them (1.4%) experienced a venous thrombosis and died due to a pulmonary embolism at 12 hours after re-PT. The other 3 patients had uneventful postoperative courses and were discharged with good pancreatic and renal function. Three patients in the bladder group (21.4%) had an anastomotic leak, which resolved with a bladder catheter. Four patients in the enteric group (7.1%) who experienced an anastomotic leak needed a second surgical procedure but in 3 of them allograft pancreatectomy was necessary. Relaparotomy was required in the other 3 patients due to hemorrhage (1 patient) or occlusion (2 patients). Acute rejection episodes, which occurred in 16 patients (22.8%), were treated with steroid boluses. With a mean follow-up of 72 months (range, 3-129), 2 patients have died at 8 and at 36 months, respectively, after SPK due to acute myocardial infarction (2.9%). Chronic rejection was the leading cause of pancreatic failure in 5 patients (7.1%) and of renal failure in 2 patients (2.8%). Patient, kidney, and pancreas survival rates were 95.8%, 92.9%, and 81.5%, respectively. Surgical complications were the leading cause of pancreatic allograft loss in IDDM and ESRD patients submitted to SPK.

Perioperative donor morbidity, a barrier to living organ donation, may be mitigated by the laparoscopic approach. From September 2002 to September 2004, 15 living donors, of ages ranging from 36 to 59 years, underwent laparoscopic nephrectomy. We used a hand-assisted device to increase the safety of the procedure. The average operating time was 200 minutes. The average blood loss was about 100 mL. The patients resumed oral intake and started walking within 1 day. The average postoperative hospital stay was 6 days. Although laparoscopic operating times were longer than those for traditional surgery, we showed benefits to the laparoscopic donor to be less postoperative pain, better cosmesis, shorter recovery time, and faster return to normal activities. We therefore consider laparoscopic nephrectomy a good alternative to traditional surgery for selected patients. Despite a lack of strong evidence, such as large prospective randomized studies, laparoscopic donor nephrectomy is likely to become the gold standard for donor nephrectomy in the near future.

We retrospectively studied the incidence of urological complications in a consecutive series of 590 patients (group B) who received a kidney transplant (KT) with a ureteral stent from January 1994 to December 2002. The ureteral stent was sewn to the bladder catheter during the surgical procedure and left in situ for a mean time of 10 days (range 8 to 12 days). The results were compared to a consecutive series of 414 patients who received a KT from March 1986 to December 1993 without a ureteral stent (group A). The two groups were comparable in terms of donor and recipient gender, ischemia time, delayed graft function, and chronic rejection incidence, but differed in mean donor age (44.1 vs 36.0 years), mean recipient age (45.4 vs 39.1 years), living/cadaveric donor rate (19.8% vs 11.9%), arterial lesions and bench reconstruction rate (11.1 vs 3.5%), as well as acute rejection episodes (11.7% vs 29.2%). Complications were seen in nine patients in group B (1.5%) and 17 patients in group A (4.1%) (P < .0001). Urinary leaks presented in two patients in group B (0.3%) and 11 patients in Group A (2.6%; P < .0001), while stenosis was present in six patients in group B (1.5%) and 7 in group A (1.2%) (P = NS). Urological complications such as urinary tract infection and macroscopic hematuria were similar in both groups. Time to presentation of a leak was within 2 weeks from KT in 10 patients (92.3%), while stenosis presented early in four patients (one in group B and four in group A). Of the stenoses, 69.3% presented late (beyond 12 weeks) in five patients in group B and three in Group A. In conclusion, our data suggest that routine use of double pigtail ureteral stent significantly decreased the incidence of leaks and early stenoses, but it did not modify late stenosis incidence. In the last decade, risk factors for urological complications have been increasing over time, namely, older donors and older recipients, living donation, length of dialysis, and the use of grafts with arterial lesions. Therefore we believe that a ureteral stent should be routinely considered to afford the advantage to protect the urinary anastomosis in the early postoperative period when the incidence of complications is highest, without the need of cystoscopy for its removal.

Background: This study evaluated the impact of surgery in the incidence of lymphocele after kidney transplantation (KTx)., Methods: A prospective randomized study was conducted during a 6-year period on a group of patients undergoing KTx and operated on by the same surgeon (CVS). A total of 280 patients undergoing KTx were randomly allocated into two groups: (1) group C (control group) was 140 patients who were submitted to KTx with standard technique: implantation of the kidney in the controlateral iliac fossa with vascular anastomoses on the external iliac vessels; and (2) group M (modified technique group) was 140 patients who underwent a modified technique with a cephalad implantation of the graft in the ipsilateral iliac fossa and vascular anastomoses in the common iliac vessels. Both groups were comparable for age, cold ischemia time, incidence of rejection episodes, presence of adult polycystic kidney disease, and source of donor graft., Results: Group M showed an incidence of lymphocele production (3 patients, 2.1%) significantly lower than group C (12 patients, 8.5%). Eight patients (1 in group M and 7 in group C) required surgical treatment by peritoneal fenestration. No allograft or recipient was lost as a result of fluid collection but the hospitalization was shorter in group M than in group C., Conclusions: A cephalad implantation of the renal graft in the ipsilateral iliac fossa has been associated with a lower incidence of lymphocele, probably because vascular anastomoses on the common iliac vessels cause less lymphatic derangement than those performed on the external iliac vessels.

Background: The surgical treatment of cancer of the cardia is controversial and results are often disappointing. Concern exists not only with regards to the surgical approach but also to the extent of the resection. The authors analyze their experience over a 20-year period adopting almost exclusively a "limited" esophagogastrectomy with a wide regional lymphadenectomy through a left thoracotomy. The aim of the study is to determine if this approach actually plays a role in the treatment of this tumor., Methods: 148 patients were evaluated for cardial cancer. Of these 22 (14.8%) were not resectable and 6 (4%) received other types of resections for technical reasons. 120 patients are the basis of the present analysis. More than 75% of patients were in stage III or IV. Follow-up was completed in 92.5% of cases; all surviving patients had at least 5 years of follow-up., Results: Four (3.3%) patients died in the postoperative period. In 6 cases (5%) an anastomotic leakage occurred and this caused the death of 2 patients. Nine (7.5%) patients had severe pulmonary complications. Dysphagia was relieved in all non complicated patients. 13 (10.8%) patients had anastomotic recurrence. Overall survival rate after 5 years was 25.62 +/- 6.1%. A significant difference in survival was noted in patients at stages II and III after 5 years (61.3% vs 18.6, p < 0.02)., Conclusions: This operation has proved to be a good option providing satisfying long-term results and a lower incidence of complications if compared with more extended procedures. It can be performed in the majority of patients with carcinoma of the cardia with a low mortality and morbidity and with excellent palliation of dysphagia. In our opinion it remains an optimum treatment for cardial cancer.

A discrepancy exists worldwide between the number of suitable liver donors and the increasing demand for transplantation. Thus many centers have considered widening their liver donor acceptance criteria and this may increase the incidence of primary dysfunction (PD) with negative effect on the results of transplantation. In order to reduce the incidence of PD and improve patient and graft survival it becomes important to identify those risk factors associated with its occurrence. In a retrospective univariate and multivariate analysis we evaluated several donor, preservation and recipient parameters and their correlation with PD. In our Department 282 orthotopic liver transplantations (OLT) were performed on 256 adult patients over a 10-year period. Excluded were 15 cases with early vascular problems and 4 intraoperative deaths. A complete series of donor, recipient and procedure-related data were analyzed. About 30% of donors showed abnormal values. In 70 cases of PD (26%) there was a 61.4% graft failure rate compared with 15% in the group with immediate function (P < 0.05). Univariate analysis showed donor age, steatosis, ischemia time, amines, oliguria, hypotension and ICU stay to be significantly associated with PD. Multivariate analysis showed steatosis, ischemia time and amine dosage to be independent risk factors for the development of primary non function. In conclusion, the acceptance of marginal donors worsened the results of transplantation, but the rejection of these donors would reduce by about 30% our transplant activity resulting in increased mortality in the waiting list. Combinations of risk factors when possible should be avoided, and ischemia time, as the only variable that can be controlled, should be kept as short as possible.

Although steroid withdrawal has been successfully performed in heart and kidney transplant recipients, no controlled studies of SW have been carried out in liver transplant patients. To evaluate this possibility a prospective controlled study was carried out in 46 liver transplant recipients operated on after may 1991. They all received a sequential quadruple immunosuppression consisting of 3 mg/kg antithymocyte globulins (RATG) for the first 5 postoperative days, cyclosporin A (starting from day 3-5 and maintaining parenteral whole-blood trough levels at 200-300 ng/ml during the first month and at 150-250 thereafter), azathioprine (1 mg/kg per day for the first month) and steroids. Prednisone was started at a dose of 200 mg per day 1 and then tapered to 20 mg/day over the first posteroperative week; this dose was maintained until day 90 when the patients were randomly allocated either to long-term steroid therapy (0.1 mg/kg per day) or to steroid withdrawal. Minimum follow-up after randomization was 6 months (6-27 months). Liver biochemistry was checked at regular intervals throughout the follow-up period. Liver biopsies were performed whenever clinically indicated and also in the first 19 patients during readmission for annual review. The incidence ot acute and chronic rejection 90 days from liver transplantation was 2.5% in patients maintained on long-term therapy. No patient in the steroid-withdrawal group had experienced either an acute or a chronic rejection episode so far. Steroid-related complications did not differ significantly between the two groups. The most recent interim analysis showed that steroid withdrawal is a safe undertaking in liver transplant recipients and may be successfully accomplished in almost all patients.

Spontaneous portosystemic shunts are commonly found in cirrhotic patients. Not yet established is their role after orthotopic liver transplantation (OLTx), especially when an increase in portal pressure develops, as during early acute rejection. In this study, 34 cirrhotic patients in a series of 70 OLTx are considered. Each patient had preoperative angiographic assessment, and, in 21 (62%), large spontaneous portosystemic shunts were evident. In 12 cases the shunts were not affected by the surgical procedure and were present during the postoperative period; in 9 the hepatectomy itself involved interruption of the shunts. The patient population was divided into two groups: patients with postoperative shunts (n = 12) and those without (n = 22). The two groups were similar in age, sex, Child's stage, transplantation variables, and number and grade of rejection episodes. However, mean transaminases (AST) values in the first 2 weeks were significantly higher levels in shunt versus nonshunt patients (421 +/- 335 vs 183 +/- 126; P less than 0.025), and this was even more evident when rejection occurred (626 +/- 375 vs 195 +/- 129; P less than 0.001). Furthermore, during an acute rejection reaction, three cases showed a true "steal phenomenon" through the large reopened shunts with ischemic damage to the grafts. The data indicate a possible detrimental effect of the spontaneous shunts on graft perfusion and suggest the prophylactic surgical interruption of the residual shunts during the transplantation.

The development of thrombotic obstruction in the portal bed of cirrhotic patients presents special problems in diagnosis and treatment. In the cirrhotic population treated for portal hypertension at our Surgical Department during the period 1967-1983 (512 patients), the incidence of thrombosis in the portal bed was 16.6% (85 patients). Bleeding was the main presenting symptom (70/85), with a mean of four episodes prior to treatment. Careful angiographic studies and intraoperative evaluation are fundamental steps to determine the exact anatomical involvement, the presence of recanalized veins or fresh occluding clots, and the applicability of shunt procedures. A massive portosplenomesenteric involvement often associated with poor surgical possibilities was found in 19 patients (22.3%). The presence of partially recanalized veins and fresh occluding clot suitable for disobliterative techniques prior to shunt was found in 16 patients, and out of 73 operated patients a total of 55 shunt procedures could be performed. Fifty-three patients who bled from varices could be followed up to 5 years: 39 underwent a shunt procedure with a 51.2% 5-year survival rate, while only one of 14 nonshunted or nonoperated survived up to 3 years, and a lethal bleeding was the cause of death in all but one. Disobliterative techniques (Fogarty thrombectomy and endovenectomy of intimal fibrotic thickenings) prior to shunting provided a good long-term patency rate with a 50% protection from lethal bleeding recurrences. Nonshunt procedures and the extensive involvement of the portal bed are associated with bad prognosis. Also, endoscopic sclerotherapy, attempted in patients with massive thrombosis, could not prevent recurrences and death from bleeding. Despite a 30% failure rate in our study, shunting surgery should be considered the only therapeutical possibility of preventing further thrombotic recurrences and consequent life threatening bleeding episodes.
