The use of Ligasure vessel sealing system in axillary dissection; effect on seroma formation.

BACKGROUND: Seroma formation is the most frequent postoperative complication after axillary dissection for breast surgery with an incidence of 10 - 50 %. This prospective clinical randomized study was carried out to evaluate the Ligasure vessel sealing system and its effect on seromaformation and other complications for axillary dissection. METHODS: Between January 2006 and November 2007, the patients with histopathological diagnosis of breast cancer were analysed prospectively. The patients with positive sentinel lymph node biopsy or clinical axillary involvement were included in the study, and the patients who underwent neoadjuvant therapy or using anticoagulants have been excluded from the study. Patients were divided into two study groups.Axillary dissection was performed in the first group by LigaSure and in the second group by linking and electrocautery. RESULTS: There were a total of thirty three patients with a mean age of 51.4 +- 13.7. In group one, mean age of patients was 54.1 +- 13.2 and 48.68 +- 14.1 in group two. There was no significant statistical difference between the groups regarding age, body mass index, excised tissue weight,tumour size and number of excised lymph nodes. The use of Ligasure reduced drainage amount and duration of drain till removal, but increased operative time. CONCLUSION: There were no significant differences between study groups regarding the complications. LigaSure electrothermal bipolar vessel sealing system can be safely used in axillary dissection as an alternative to traditional methods.

Laparoscopic treatment of splenic lymphangiomas: report of three cases.

BACKGROUND AND AIM: Since 1991, laparoscopic splenectomy has been performed in many different pathologies of the spleen. Although it is a rare lesion, splenic lymphangiomas are cystic lesions of the spleen requiring splenectomy. Herein, we present three females who have undergone laparoscopic splenectomy with the diagnosis of cystic splenic lymphangioma. PATIENTS AND METHODS: In the last four years, in Istanbul Medical School, Department of General Surgery (Turkey) and in University of Catania Medical School, Department of Surgery (Italy), we performed laparoscopic splenectomy in three cases of splenic lymphangioma. RESULTS: These three female patients, with the age of 26, 30 and 40, had nonspecific abdominal pain requiring abdominal CT scan and magnetic resonance imaging, which showed incidental cystic lesions in the spleen, associated with cholelithiasis in one case. Preoperative laboratory tests and physical examinations were normal. Laparoscopic splenectomy was performed successfully with three 10 mm trocars in two patients in less than 1 hour, and with an Hasson trocar, two 5 mm trocars and one 10-12 mm trocar in the last case, who required simultaneous cholecystectomy. No peroperative and postoperative complications has occurred. Histopathological examinations confirmed the preoperative diagnosis. CONCLUSION: Laparoscopic splenectomy is the best treatment for patients with suspected cystic lymphangioma. It permits a total pathological examination of the spleen, and it should be preferred to partial splenectomy because of possible multiple lesions. In conclusion, minimal invasive treatment of this rare pathology is an effective and safe procedure.

'Use of electrothermal vessel sealing with LigaSure device during laparoscopic splenectomy'.

PURPOSE: Main causes of conversion to open surgery are uncontrolled bleeding from splenic hilum and capsular injury of spleen during laparoscopic splenectomy (LS). We present the use of LigaSure in laparoscopic splenectomy for hemostasis. MATERIAL & METHOD: Between January 2005 and May 2006, LS was performed in a total of 29 patients (6 male and 23 female) with a mean age of 35.44 +/- 13.63. Indications for splenectomy were idiopathic thrombocytopenic purpura (ITP) in 20 patients, thrombotic thrombocytopenic purpura (TTP) in 2, hereditary spherocytosis (HS) in 3, lymphangioma in 2, hodgkin lymphoma in 1 and splenic cyst in one patient. LS was performed in the right semilateral position with three 10 mm trocars. LigaSure was used in dissection and division of splenic ligaments and hilar vascular structures. RESULTS: Conversion to open surgery was necessary in one patient due to peroperative bleeding. The mean duration of the operation was 71.3 +/- 19.8 minutes and the estimated blood loss was 85 +/- 23 ml. The diameter and the weight of the spleen were 10.7 +/- 2.68 cm and 250 +/- 90 g, respectively. There was no mortality. Postoperative complications included pancreatic fistula, trocar site infection and deep venous thrombosis that were encountered in three patients. These were managed without morbidity. The overall complication rate was 10.3% (n = 3). The mean duration of postoperative hospital stay was 2.86 +/- 1.59 days. CONCLUSION: LigaSureTM use in LS had easy application, provided sufficient hemostasis, and shortened the operative time.

The comparison of laparoscopic and open ventral hernia repairs: a prospective randomized study.

BACKGROUND: The laparoscopic approach has emerged in the search for a surgical technique to decrease the morbidity associated with conventional repair of ventral hernias. In this study we aimed to compare the results of our open and laparoscopic ventral hernia repairs prospectively. METHODS: Between January 2001 and October 2005, a total of 46 patients diagnosed with ventral hernias (primary and incisional) who were admitted to our surgical unit and accepted to be included in this study group were examined. All patients were divided into laparoscopic repair (n = 23) and open repair (n = 23) subgroups in a randomized fashion. The patients' demographic characteristics, operation times, body mass indices, sizes of fascial defects, hernia locations, durations of hospital stay, presence and degrees of postoperative pain, and postoperative minor and major complications were analysed and compared. All the data were expressed as means +/- SDs. Chi-square and Wilcoxon tests were used for statistical analysis, and P < 0.05 was accepted as a significant statistical value (SPSS 11.0 for Windows). RESULTS: The demographic characteristics of both groups were similar. Women predominated, especially in the laparoscopy group (P < 0.05). The comparison of the results revealed that the major advantage of laparoscopy was the shortened postoperative hospital stay and the reduced incidence of mesh infection (P < 0.05, P < 0.05). On the other hand, operation time was significantly longer in the laparoscopy group (P < 0.05). The major complications encountered in the laparoscopy group were ileus and a missed enterotomy. The most frequent minor complication was seroma, which was significantly more frequent in the laparoscopy group (P < 0.05). Postoperative pain assessment revealed similar results in both groups (P > 0.05). CONCLUSIONS: The laparoscopic approach appears to be as effective as open repairs in the treatment of ventral hernias. Advanced surgical skill, laparoscopic experience and high technology are mandatory factors for successful ventral hernia repair.

[Negative laparotomies in gunshot and stab injuries of the abdomen]. / Negative Laparotomien bei Schuss- und Stichverletzungen des Bauches.

A selective approach is taken, as a matter of principle, to cases of abdominal injuries at the Traumatological Department of the Faculty of Medicine at Instanbul University. Surgical treatment was applied to 378 in 2,968 hospitalised patients for contused or penetrating abdominal injuries, in 1983 and 1984. The rate of negative laparotomy was as low as 7.3 per cent owing to routine peritoneal flushing. However, laparotomy has been preferred and resulted in a negative laparotomy rate of 21 per cent, since problems are quite often faced in the diagnosis of stab injuries.
