Incidence and risk factors of chylous ascites after colorectal cancer surgery

Background

The aim of this study was to identify possible risk factors associated with chylous ascites after colorectal cancer surgery.

Methods

Patients who underwent colorectal cancer resection were enrolled in this study. Data were compared between patients who developed chylous ascites and those who did not.

Results

Chylous ascites was detected in 48 (6.6%) patients. There were significant differences between the groups with and without chylous ascites in terms of age (65.6 vs 61.6 years, P = .017), operator (5.0% vs 15.5%, P < .001), operative procedure based on tumor location (P = .041), operative time (206.0 vs 229.8 minutes, P = .045), and blood loss (78.1 vs 219.7 mL, P = .036). After subgroup analysis for right-sided colectomy and low anterior resection to compensate for the effects of the operative procedure, the differences in the operative time and blood loss were not significant. In most patients, chylous ascites was resolved with conservative management.

Conclusions

Chylous ascites developed significantly more frequently in patients who underwent right-sided colectomy and in elderly patients. In addition, the incidence was also dependent on the operator. Conservative treatment was effective in most patients.     

‘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, lymphan-gioma 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: LigaSure? use in LS had easy application, provided sufficient hemostasis, and shortened the operative time.     

Laparoscopic Decortication of Hilar Renal Cysts Using LigaSure

Background and Objectives:

In this study, we evaluated the safety and efficacy of using the LigaSure sealing system (Valleylab, Boulder, Colorado) for laparoscopic decortication of symptomatic hilar renal cysts.

Methods:

Seventeen patients underwent laparoscopic decortication of hilar renal cysts with the LigaSure system. Our study included only symptomatic, Bosniak type 1, simple and symptomatic renal cysts. The operative route, transperitoneal or retroperitoneal, was planned according to the location confirmed by computed tomography. The patients'' symptoms were preoperatively and postoperatively evaluated by the Wong-Baker visual pain scale. Operative measures and radiologic outcomes were prospectively evaluated.

Results:

The mean age of the patients was 56.4 years, and the mean follow-up period was 12.5 months. Preoperative computed tomography showed only a single cyst in 15 patients (88.2%) and showed two separate cysts in 2 cases (11.8%). The cysts were located in the perihilar region close to the vascular structure in all patients. A transperitoneal approach was used in 9 patients, and a retroperitoneal approach was used in 8 patients. The mean operative time and hospitalization time were 56.4 minutes and 1.2 days, respectively. Minor complications were observed in 3 patients. Symptomatic and radiologic success rates of 94.2% and 100%, respectively, were achieved.

Conclusion:

Laparoscopic decortication of symptomatic hilar renal cysts—first reported in the literature in this study—using the LigaSure sealing system is feasible, effective, and safe, even if the cyst is located in the perihilar area.
