Hand-assisted laparoscopic and laparoscopic donor nephrectomy: A comparison of surgical outcomes from two centres.

OBJECTIVE: The aim of the study was to compare the different surgical approaches of two centers on outcomes of live donor laparoscopic nephrectomy. MATERIAL AND METHODS: The first 98 patients of each centre who underwent laparoscopic donor nephrectomy (LDN) or hand-assisted laparoscopic donor nephrectomy (HALDN) were included in the study. The following data were used for analyses: donor age, weight, height, body mass index (BMI), transfusion requirement, operative time, ischemia time and postoperative complications. RESULTS: Median age, BMI, operation time and estimated blood loss (EBL) was 47.29 years, 27.91 kg/m2, 110.73 minutes, and 78.95 mL, respectively. Operation time was significantly shorter in the HALDN group (t=-3.554, p<0.01). EBL was not significantly different between the two groups. The difference in hospitalization time and warm ischemia times (WIT) was not significant between the two surgical technique groups (t=-1.554, t=1.258; p>0.05). No statistically significant difference was detected in the intraoperative and postoperative complication rates between two groups (p>0.05). The postoperative complication rate was 7.14% (n=7) and 6.12% (n=6) in the LDN and HALDN groups, respectively. There were two patients with conversion to open surgery in the HALDN group because of lumbar vein injury. CONCLUSION: The operative and postoperative outcomes for the two techniques were found to be similar. The HALDN technique preserves the benefits of minimally invasive surgery. In experienced urologic laparoscopy centres both techniques promise similar success rates.

Laparoscopic repair of Morgagni hernia.

BACKGROUND: Morgagni hernia is a rare type of diaphragmatic hernia which represents less than 5% of all congenital diaphragmatic hernias. Patients are generally asymptomatic and are diagnosed incidentally. When symptomatic, it generates symptoms due to the compression of thoracic organs or compression of herniated intraabdominal organs. Once diagnosed, the condition requires prompt surgical correction. The defect is repaired either by primary suture or by the use of a prosthetic mesh. In adults, prosthetic mesh repair is preferred. Recently, laparoscopic repair of Morgagni hernia has been introduced and gained wide acceptance. MATERIALS AND METHODS: Between 2002 and 2004, 5 patients with Morgagni hernia were treated laparoscopically at our department. Female/male ratio was 3/2. Mean age was 56 years (range 41 to 69 y). Diagnosis were made by chest x-ray and CT scan. Herniation was on the left in 2 patients, and on the right in 3. The content of hernial sac was transverse colon and stomach. There were 2 separate defects in a patient with left-sided hernia. All cases were laparoscopically treated using prosthetic material. RESULTS: All operations were completed laparoscopically. The postoperative hospital stay was 3 to 5 days with a mean of 4 days. None of the patients developed any complication in the early postoperative period. The mean follow-up period is 7 months (range 3 to 24 mo). All patients are actually in good health and without recurrence. CONCLUSION: Laparoscopic repair of Morgagni hernia is a safe, simple, and reliable procedure which presents all the advantages of the minimally invasive surgery.

Effects of hyperbaric oxygen and Pgg-glucan on ischemic colon anastomosis.

AIM: In colorectal surgery, anastomotic failure is still a problem in ischemia. Here,we analyzed the effects of hyperbaric oxygen and beta-glucan on colon anastomoses in ischemic condition. METHODS: Colonic resection and anastomosis in rectosigmoid region were done in forty Wistar-Albino rats of four groups of equal number. Colon mesentery was ligated to induce ischemia. The first group was the control group. The subjects of second group were treated with hyperbaric oxygen;the third group with glucan and the forth group were treated with both. At the forth day, rats were sacrificed,anastomotic segment was resected and burst pressures and hydroxyproline levels of anastomotic line were measured. RESULTS: The burst pressure difference of second and third groups from the control group were meaningful (P<0.01); the forth group differed significantly from the control (P<0.001). There was no difference between the treated groups on burst pressure level (P>0.05). The hydroxyproline levels in all treated groups were different from the control group significantly (P<0.001). Hydroxyproline levels in the forth group were higher than those of the second and the third groups (P<0.001). There were no significant differences between the second and the fourth groups in burst pressure and hydroxyproline levels (P>0.05). CONCLUSION: Hyperbaric oxygen and glucan improve healing in ischemic colon anastomoses by anti-microbic,immune stimulating properties and seem to act synergistically when combined together.

Laparoscopic repair of ventral and incisional hernias: our experience in 150 patients.

BACKGROUND: Incisional hernias develop in 2 to 20% of laparotomy incisions. Approximately 100,000 ventral hernias are operated on each year in the United States. The reported recurrence rates for open repair are 25-52% for primary and 12.5-19% for mesh repair. Compared to the open technique, laparoscopic repair has low rates of complications and recurrence, greater patient acceptance, and shorter hospital stay. MATERIALS AND METHODS: Between April 1999 and April 2004, we treated 150 patients (111 female, 39 male) with ventral and incisional hernias laparoscopically. Data concerning the age and sex of patients, the location, number, and size of fascial defects, the type of hernias and their contents, the size and type of meshes used in repair, operative time, length of hospital stay, and postoperative complications were collected. RESULTS: Of the 150 patients, 92 had incisional hernias and 58 had umbilical hernias. Polypropylene was used in 85 cases, dual mesh in 40 cases, and composite mesh in 25 cases. The mean age of the patients was 56.0 years (range, 33-81 years). Mean operative time was 63 minutes (range, 30-125 minutes). Mean postoperative hospital stay was 2.5 days (range, 1-15 days). The postoperative complication rate was 8.6% (seroma, paralytic ileus, small bowel injury, and suture-site neuralgia). The mean follow-up period was 32 months (range, 4-60 months). There was a 3% recurrence rate. Three subileus cases were detected during follow-up. CONCLUSION: The laparoscopic approach to ventral and incisional hernias is safe, feasible, and a good alternative to the open approach. Our results are comparable with those of other reports in the literature.

Fournier's gangrene: a retrospective clinical study on forty-one patients.

BACKGROUND: Fournier's gangrene, first described by Dr Jean Alfred Fournier in 1883, still has a high mortality rate. The prognosis and outcome of such patients were analysed. METHODS: Forty-one patients with Fournier's gangrene were reviewed on the parameters of age, sex, aetiological agents, predisposing factors, treatment modalities and outcomes. RESULTS: Although early intervention and careful treatment was carried out, nine of 41 patients (21.9%) died as a result of complications of septicemia. Among the treatment modalities, there were extensive debridement, drainage, excisions of the skin and fascia, colostomy procedure, extensive antibiotic treatment and hyperbaric oxygen therapy. Although a combination of different treatment modalities were used, the mortality rate was 21.9%. CONCLUSIONS: Fournier's gangrene is still a severe disease. Today, hyperbaric oxygen treatment is very effective in the treatment of this disease.

Zinc and copper status in acute pancreatitis: an experimental study.

Metal ions are required as active components of several proteins, including pancreatic enzymes, and they can play important roles in the etiopathogenesis of acute pancreatitis. In the present study, we measured the concentrations of zinc (Zn) and copper (Cu) in both serum and pancreatic tissue, as markers of trace element status in an experimental acute pancreatitis model. Twenty-four male Wistar rats were divided into two groups: the experimental group (N=24) and the control group (N=10). Acute pancreatitis was induced by injection of 48% ethyl alcohol into the common biliary duct. The animals were sacrificed 24 h later to detect the concentrations of Zn and Cu. There was no significant difference in tissue Zn and Cu concentrations between control and experimental groups (p<0.05). However, in the acute pancreatitis group, serum Zn and Culevels were very significantly lower (p<0.001 and p<0.0001, respectively). In conclusuion, these findings suggested that altered mineral metabolism in serum and pancreatic tissue may have contributed to the pathophysiology of acute pancreatitis.
