RESUMEN

BACKGROUND: This study aimed to evaluate the effect of fibrin glue in laparoscopic spleen-preserving procedures for traumatic rupture. METHODS: From January 2002 to December 2005, six laparoscopic spleen-preserving procedures were performed for traumatic rupture using fibrin glue. Two of the cases had previous middle and lower abdominal surgery. Survey of the abdominal cavity was performed by inserting two 5- to 12-mm trocars, one 5-mm trocar, and a 30 degree scope. A complete survey of all the patients was performed. RESULTS: None of the patients required laparotomy, and no postoperative bleeding occurred. The fibrin sealant achieved immediate hemostasis, and all the patients recovered without further splenic bleeding. The mean postoperative stay was 4.3 days (range, 4-5 days). All the patients were followed up for 3 to 12 months. Postoperative immunoglobulin scanning, ultrasonography, and computed tomography (CT) results were normal. CONCLUSIONS: Laparoscopic management of spleen trauma can be used once a positive diagnosis has been made. It is useful for assessing the degree of splenic injury. A laparoscopic spleen-preserving procedure can be used safely for patients with stable vital data. It is an effective procedure for the evaluation and treatment of hemodynamically stable patients with splenic injuries for whom nonoperative treatment is controversial. The topical application of a fibrin sealant in splenic trauma achieves definitive hemostasis safely, rapidly, and reliably. It also is simple to use in either laparoscopic or open procedures.

RESUMEN

BACKGROUND: Incisional hernia is a common complication of abdominal surgery, and it is often a source of morbidity and high costs for health care. This is a case-control study to compare laparoscopic versus anterior-open incisional hernia repair. METHODS: 170 patients with incisional hernia were enrolled in this study between September 2001 and December 2004. Of these, 85 underwent anterior-open repair (open group: OG), and 85 underwent laparoscopic repair (laparoscopic group: LG). The clinical outcome was determined by a median follow-up of 24.0 months for LG and OG. RESULTS: No difference was noticed between the two groups in age, American Society of Anesthesiologists (ASA) score, body mass index (BMI), and incisional hernia diameter. Mean operative time was 61.0 min for LG patients and 150.9 min for OG patients (p < .05). Mean hospitalization was 2.7 days for LG patients and 9.9 days for OG patients (p < .05). Mean return to work was 13 days (range, 6-15 days) in LG patients and 25 days (range, 16-30 days) in OG patients. Complications occurred in 16.4 % of LG patients and 29.4 % of OG patients, with a relapse rate of 2.3% in LG and 1.1% in OG patients. CONCLUSIONS: Short-term results indicate that laparoscopic incisional hernia repair is associated with a shorter operative time and hospitalization, a faster return to work, and a lower incidence of wound infections and major complications compared to the anterior-open procedure. Further studies and longer follow-up are required to confirm these findings.

RESUMEN

INTRODUCTION: The aim of this study was to establish the efficacy and tolerability of human fibrin glue (Tissucol) for the nontraumatic fixation of a composite prosthesis (Parietex) in the laparoscopic repair of small to medium-sized incisional hernias and primary defects of the abdominal wall. MATERIALS AND METHODS: From October 2003 to October 2005, 40 patients underwent laparoscopic repair at the hands of one surgeon with expertise in laparoscopic surgery; all meshes were implanted in an intraperitoneal position. Follow-up visits were scheduled for 7 days and 1, 6, and 12 months. These included assessments for pain and postoperative complications. RESULTS: Forty patients (24 females, 16 males) with a mean age of 50 years (range, 26-65 years) and a mean Body Mass Index (BMI) of 27 (range 25 to 30) were included in the study. Sixteen patients had incisional hernias, and 24 had primary defects. The size of the defects varied from 2 to 7 cm. Adhesiolysis was necessary in 92.5% of cases (25/40). There were no intraoperative complications or conversions. After a mean follow-up of 16 months (range, 3-24 months), no postoperative complications were observed. The mean surgical intervention time was 36 min (range, 12-40 min), with an average hospitalization time of 1 day. CONCLUSIONS: The use of fibrin glue in the present study provided stable and uniform fixation of the prosthesis and minimized intraoperative and postoperative complications. Consequently, laparoscopic treatment of small to medium-sized abdominal defects using this approach is our therapeutic option of choice.

RESUMEN

BACKGROUND: The efficacy and safety of prosthesis fixation were studied by means of fibrin glue (Tissucol, Baxter Healthcare) during laparoscopic transabdominal preperitoneal (TAPP) treatment of inguinal and femoral hernias. METHODS: Between September 2001 and December 2004, fibrin glue was used for mesh fixation during TAPP. RESULTS: In this study, 320 hernias were treated for 230 patients (225 men and 5 women) with an average age of 45 years (range, 20-75 years). No perioperative complications were observed. After an average follow-up period of 26 months (range, 1-40 months), the only postoperative complications observed were six seromas (1.8%) and one trocar-site hematoma (0.3%). The mean operating time was 30 min for unilateral hernias and 50 min for bilateral hernias, whether primary or recurrent. Patients usually were discharged the day after surgery and returned to work after 5 days. CONCLUSIONS: The authors' experience demonstrates that fibrin glue (Tissucol) is an effective method for mesh fixation during TAPP.

RESUMEN

Cell-mediated immunodeficiency, with Total and T lymphocytes count decrease, is well established in cancer patients and it predicts a poor prognosis and poor survival rates. Furthermore, major surgery induces a transient immunodeficiency, too. Nevertheless, cell-mediated immunity in pancreatic cancer, which has a very poor prognosis, has not been completely outlined. Aim of this study is to evaluate the cell-mediated IL-2 dependent immune status in operable pancreatic cancer patients and to compare it with other gastrointestinal tumors. One hundred and twenty-one cancer patients (22 pancreatic, 48 gastric and 51 colorectal), with a median age of 66 years (range 42-83), 55 males and 66 females, were enrolled. Total lymphocyte count and lymphocytes subset (T helper count - CD4+) were assessed preoperatively and on the 14th and 50th postoperative day. Results obtained were compared between the groups and related to nodal involvement (N0 versus N+). Colorectal and gastric cancer patients showed quantitative lymphocyte deficiency at baseline in 29% and 41% of cases, respectively. Fourteen days after surgery values below normal range were found in 44% and 54% (Total) and 53% and 67% (T helper), respectively. Recovery of postoperative surgery-related lymphocytopenia occurred late only in patients with normal count at baseline. According to regional nodal involvement (pN0/N+) T helper deficiency was significantly more frequent in patients with nodal involvement than in patients without. In pancreatic cancer, percentage of immunodepressed patients at baseline was higher compared to the other two groups (71%). Lymphocyte count was significantly different between pancreatic and gastric/colorectal cancer, reaching a statistical significance at baseline and on the 14th and 50th postoperative day. No differences of T helper deficiency were noted according to nodal involvement (N0 versus N+) neither at baseline nor in the postoperative period. In conclusion, the degree of immunosuppression varies among different tumor types: since initial stages of disease, immunodepression was significantly greater in pancreatic cancer which should be considered always a systemic disease even in early stages and indipendently from the nodal involvement and from tumor load.

RESUMEN

BACKGROUND: Gastrointestinal carcinoid tumors are rare and little is known about factors related to prognosis in patients with carcinoid disease. Aim of this study is to determine the impact of clinical presentation variables on the management and survival. METHODS: We have evaluated 31 consecutive patients with gastrointestinal carcinoid tu-mours who underwent surgical intervention at the I Department of Surgery of Milano-Bicocca University over 15 years (1985-1999). Tumor distribution, hormone production, prognostic factors and survival were analysed. RESULTS: Carcinoid syndrome was the only clinical pattern diagnostic of carcinoid tumour. Most common symptoms were abdominal pain (64%), nausea and vomiting (48%). High levels of urinary 5-hydroxyindolacetic acid were significantly associated with carcinoid syndrome and metastatic disease. Tumor size, depth and gender were significant predictors of metastases. Age, gender, tumor size, metastatic spread and location were statistically significant predictors of death. CONCLUSIONS: Clinical presentation was non specific except for those patients affected by carcinoid syndrome. Ten years overall survival was 43%, with 52% metastatic spread incidence. The extent of surgical resection should be modulated on patient related risk factors. Poor prognostic factors affecting survival were: age, gender, metastatic disease, depth of invasion and tumour size.

RESUMEN

We have shown that actively phagocytosing human polymorphonuclear leukocytes (PMN) float on top of the incubation medium when Oil Red O containing paraffin oil particles (density 0.8740) are used as the phagocytosable material. This implies that the quantitation of phagocytosis based on the recovery of Oil Red O in phagocytosing cells pelleted after centrifugation would be underestimated. We therefore prepared particles of progressively increasing density by mixing paraffin oil (density 0.8740) with silicon oil (density 1.0802). Cell flotation also occurred with paraffin oil-silicon oil particles and could be avoided only when the density of the particles used had reached 0.9952 g/cm3. Paraffin oil-silicon oil particles of a density sufficient to dissolve the dye Oil Red O were therefore used to quantitate both the initial rate of phagocytosis and the phagocytic capacity of human PMN. With this assay the initial rate of phagocytosis was found to be 400 micrograms paraffin oil-silicon oil/min/5 X 10(6) PMN, which is about 20 times higher than that reported for the same cell type using paraffin oil particles. The calculated maximum phagocytic capacity was 2.5 mg paraffin oil-silicon oil/5 X 10(6) PMN. The uptake of paraffin oil-silicon oil particles was sensitive to inhibitors of phagocytosis, such as N-ethylmaleimide, papaverine and cytochalasin B, in a dose dependent manner. The assay also permitted the detection of increased phagocytosis such as occurs in myeloperoxidase deficient PMN.
