Background: The effectiveness of endoscopic clipping in the hemostasis of bleeding esophageal varices and the eventual variceal eradication was compared with that of band ligation. Methods: Forty patients were enrolled in the study in a prospective manner, 19 of whom received endoscopic clipping (group I) and the remaining (n = 21 patients) received endoscopic band ligation (group II). All patients in this study presented with bleeding from esophageal varices. The patient characteristics (age, sex, Child–Pugh score, variceal grade) were comparable in the two groups. After initial hemostasis, the patients were assigned one of the two forms of endoscopic therapy which was continued in the follow-up sessions until varices were eradicated. Early and late results were compared. Results: Initial hemostasis was achieved in all patients in group I but two patients in group II required clip ligation for initial hemostasis because of the failure in band ligation. Those two were treated with band ligation in the follow-up sessions. A total of 224 clips in 53 treatment sessions and 296 bands in 82 treatment sessions were placed in group I and group II, respectively. The rates of complete variceal eradication were 89% and 76% in group I and group II, respectively (p > 0.05). The median number of required treatment sessions for complete eradication of the varices was significantly lower in group I than group II (3 versus 4, p = 0.013). Three patients from group I (15%) and seven patients from group II (33%) were readmitted for variceal bleeding during the follow-up period (p > 0.05). Conclusions: With the advantages of high initial hemostasis rate, decreased risk of rebleeding, and fewer treatment sessions needed for variceal eradication, endoscopic clipping is as effective as band ligation, or perhaps more effective in the treatment of bleeding esophageal varices.

Although tension-free techniques of hernia repair using synthetic meshes have yielded encouraging results, the best method of inguinal hernia repair is still unclear. The aim of this study was to compare the responses of inflammatory mediators and postoperative pain relief following laparoscopic total extraperitoneal (TEP) hernioplasty, open tension-free mesh hernioplasty (Lichtenstein), posterior preperitoneal mesh hernioplasty (Nyhus procedure), and Bassini procedure. Patients with primary inguinal hernia were randomized in the operating room to undergo one of these repair techniques. Group I comprised 24 patients treated by Lichtenstein procedure; Group II comprised 21 patients treated by Nyhus procedure; Group III comprised 19 patients treated by Bassini procedure; and Group IV comprised 20 patients treated by laparoscopic TEP mesh hernioplasty. Postoperative pain levels following hernia repair were compared by measuring the use of patient-controlled analgesia (PCA) during the 24 hours after surgery. Serum samples withdrawn before surgery and 48 hours after surgery were assayed for C-reactive protein (CRP) content. Patient characteristics, operating time, and operative and early complications were noted. Serum CRP levels rose markedly following Nyhus (184.5 ± 41.6 mg/L), Lichtenstein (138.4 ± 72.5 mg/L), and Bassini repair (137.2 ± 55.9 mg/L) compared with that of patients who underwent TEP mesh hernioplasty (55.5 ± 41.2 mg/L). There were also significant differences in the postoperative need for analgesics via PCA among patients undergoing Nyhus (382.9 ± 189.1 mg), Bassini (303.2 ± 173.7 mg), and Lichtenstein (253.9 ± 129.3) procedures compared with 196.6 ± 148.8 mg for the TEP mesh hernioplasty group. Patients in the Lichtenstein group also had significantly less need of analgesics than those in the Nyhus and Bassini groups. In conclusion, TEP mesh hernioplasty is less traumatic and yields less postoperative pain than the Nyhus, Lichtenstein, and Bassini procedures.

OBJECTIVE The purpose of this study is to investigate the effects of diphenhydramine-HCl and Na-hyaluronate derivatives on the development of postoperative peritoneal adhesion and tubal obstruction. STUDY DESIGN Forty female rats of Sprague-Dawley type were used in the study. The rats were divided into four groups, each comprising 10 subjects. After all the rats were anaesthetized with 50mg/kg ketamine HCl, their abdomens were opened with a lower midline incision. Injury was induced on the right pelvic peritoneum and on the peritoneal surface of left uterine tube. No additional procedure was applied to the first group. 10 mg/kg diphenhydramine-HCl was given to the second group intravenously. In the third group, 0.25 mg/kg Orthovisc, a Na-hyaluronate derivative was diluted with 2 ml physiological saline and poured into the abdomen. For the fourth group, Seprafilm, a Na-hyaluronate derivative was covered in a layer of 0.7 cm x 3 cm over the left uterine tube. After 14 days, the rats were anaesthetized with ketamine HCl again, and 5 cm(3) blood sample was taken with cardiac puncture. The abdomen was opened with an incision transverse to the upper end of the midline incision, and the presence of adhesions was investigated. Detected adhesions were staged according to the Mazuji classification. Tubal patencies were inspected by injecting methylene blue from the uterine corpus into the lumen using an injector. A piece of abdominal wall of 4 cm x 4 cm was removed by extending the incision in the reverse U shape. The tensile strength and bursting pressure of the suture line were determined using the Peacock method. One gram of tissue was taken from the incision line, and hydroxyproline levels were determined by the Bergman-Loxley method. Aspartate aminotransferase (AST) levels were measured. RESULTS All of the rats completed the study. AST levels, tissue hydroxyproline levels and tensile strength and bursting pressure test results were found to be similar in all groups. While adhesion rates in the groups were 100, 40, 40 and 30%, respectively, adhesion stages were found to be, respectively as 2.1+/-1.7, 0.6+/-0.67, 0.6+/-0.67 and 0.5+/-0.85. Adhesion stages in the study groups were significantly lower (P<0.05). Tubal obstruction rates were found to be 70, 30, 30 and 20%, respectively. CONCLUSION Diphenhydramine, Orthovisc and Seprafilm significantly reduce postoperative peritoneal adhesion development, and they allow the uterine tubes to remain open.

Serdar Yol; Sakir Tavli; Lema Tavli; Metin Belviranli; Alper Yosunkaya

The case of a 63 year-old man with a giant scrotal and retroperitoneal tumor is herein reported. The initial symptoms began in the scrotum and subsequent abdominal distention resulted in discomfort 2 years later. The intraabdominal organs were under pressure because of the bulky mass, and the patient had dyspnea. Ultrasonograpy, computed tomography, and fine needle aspiration biopsy investigations all revealed a retroperitoneal tumor suspected to be liposarcoma. At operation, a tumor weighing 42 kg was excised. Respiratory support was provided in the early postoperative period. The histopathological diagnosis was myxoid liposarcoma. The patient was discharged from the hospital 14 days after the operation and was scheduled to undergo radiotherapy.

PurposeThe aim of this study was to present the long-term follow-up results of liver hydatid cysts treated with unroofing, together with a review of the related literature data.MethodsOf 700 liver hydatid cyst patients examined and treated at Selcuk University Meram Medical Faculty, General Surgery Department, between 1985 and 2007, 650 had accessible data and the unroofing method had been applied in 189 of them. The clinical and laboratory findings, stages, operations, and complications of patients treated with unroofing were reviewed. In particular, the resolution of residual cyst cavities over time after the application of this method was evaluated using computed tomography.ResultsFour hundred and thirty-six (67.07%) of the cases were female [mean age: 35 (range: 10–73) years] and 214 (32.9%) were male [mean age: 46 (range: 12–76) years]. Of the 189 cases treated with unroofing and followed by tomography, the data of 144 were documented. Cavities were classified into five groups (A-E) according to their postoperative appearance.ConclusionsUnroofing is an easy approach and it does not require extensive experience. This technique is recommended for peripherally localized cysts but may also be applied to those more deeply situated. Unroofing should be applied as deeply as possible and the residual cavity should also be as shallow as possible.

Octreotide (Sandostatin 201-995) has aninhibitory effect on gastric, intestinal, and pancreaticsecretions and hepatic and splachnic blood flow. Weexamined the effects of octreotide on bile flow and bile components in 10 patients with T-tubecholedochostomy. A Fogarty balloon catheter was inserteddistal to the T-tube of these patients for measurementof bile flow and bile components. Bile samples were obtained to analyze bile acid, phospholipid,lipoprotein, and cholesterol, and bile flow measurementswere performed every 15 min for a period of 90 minbefore study and after normal saline and octreotide administrations. While octreotide had aninhibitory effect on bile flow, the concentrations ofbile acid, phospholipid, and lipoprotein in bile wereincreased with octreotide.

Objectives: To evaluate internal herniation as a rare cause of intestinal obstruction.Materials and Methods: Files of 18 cases, operated due to internal herniation between 2000 and 2006 at Selcuk University, Meram School of Medicine, General Surgery Department, were reviewed retrospectively. Sixteen patients (88.8%) were male (mean age: 58.2 years; range: 42–67) and 2 were female (mean age: 56.5 years; range: 52–61).Cases were grouped according to the location of internal herniation, and the clinical findings and applied treatment strategies were evaluated. Results: All patients were taken into surgical operation after preoperative preparations were completed. Findings were as follows: 6 cases of paraduodenal internal herniation, 4 of internal herniation through a defect in the terminal mesoileum, 2 of herniation through a defect in the falciform ligament, 2 of herniation through a defect in the omentum majus, 1 of herniation to the recessus over the bladder, 2 of herniation through a defect in the transverse mesocolon and 1 iatrogenically caused internal herniation through a defect in the mesojejunum. Conclusion: In an adult patient with findings of intestinal obstruction, diagnosis is difficult. Most cases presented to date are incidental findings during laparotomy, and surgical treatment is necessary.

BACKGROUND The aim of the present study was to compare the hemodynamic and metabolic effects of extraperitoneal carbon dioxide (CO(2)) and nitrous oxide (N(2)O) insufflation. MATERIAL AND METHODS Fourteen dogs were used in the experiment. All the animals were intubated under general anesthesia. A catheter was placed into the right jugular vein for central venous pressure (CVP), pulmonary artery pressure (PAP), pulmonary wedge pressure (PWP), and heart rate (HR) monitorization. End-tidal CO(2) pressure was measured by a capnometer connected to the endotracheal tube. Another catheter was inserted into the left femoral artery for arterial blood gas analysis and blood pressure monitorization. The preperitoneal dissection was made from a 1.5 cm subumbilical incision by using a preperitoneal dissection balloon. A laparoscope was placed in the preperitoneal space and the gas insufflation was kept at a constant pressure of 12 mm Hg throughout the experiment. All the study parameters were measured at the beginning of the insufflation and at every 15 minutes for 1 hour. RESULTS Mean artery pressure increased with time in both groups, but the increase was only significant in the CO(2) group. PWP, CVP, PAP, and HR increased slightly in both groups, but there was no significant difference between the groups. The end-tidal CO(2) increased in the CO(2) group but decreased from the baseline in the N(2)O group. A significant acidosis was observed in only the CO(2) group. PaCO(2) significantly increased in the CO(2) group; hence, PaCO(2) slightly decreased in N(2)O group. The difference between the groups was significant. CONCLUSIONS N(2)O insufflation of the extraperitoneal space in dogs avoided the unwanted metabolic and hemodynamic side effects of CO(2) insufflation. Thus, N(2)O insufflation in the extraperitoneal space is a safer alternative to CO(2) insufflation experimentally, and can be preferred especially in patients with cardiac and pulmonary diseases.

INTRODUCTION The purpose of this study is to investigate the effectiveness of Collagenase clastridiopeptidase an enzyme preparation used in enzymatic debridement in preventing adhesions brought about by peritoneal damage. METHODS The study covers a total of 40 rats in 4 groups each having 10 rats. Group 1: The control group. Group 2: Normal saline group. Group 3: Sterile Novuxol group. Group 4: The group where the intraperitoneal and systemic effects of sterile Novuxol were investigated. Adhesion frequency and grades were scored on the post-op 11th day according to Granat. Blood work including hemoglobin, aspartate aminotransferase, alanine aminotransferase, urea, creatinine, and albumin level measurements were performed. Toxicity was investigated histopathologically through samples taken from the liver and the peritoneum from Group 4. RESULTS Adhesion frequency was found to be 80% on the right and 90% on the left for Group 1, while it was 50% on both left and right for Group 2, and 30% on the right and 10% on the left for Group 3. Adhesion stages were found to be 1: 2.35 ± 1.42 for Group 1, 0.31 ± 1.15 for Group 2, and 0.20 ± 0.41 for Group 3. Adhesion stage of the Sterile Novuxol Group was lower than all the other groups (p < 0.05). Biochemical and hematological parameters were similar in all groups (p > 0.05). Histopathological analysis revealed no hepatotoxicity. CONCLUSIONS According to the results of our study, we believe that Sterile Novuxol can be a good anti-adhesive agent considering its ease of use, non-toxicity, and effectiveness.
