Laparoscopic surgery in great adrenal malignant masses. / Cirugía laparoscópica en grandes masas suprarrenales malignas.

OBJECTIVE: The aim of this article is to describe the surgical technique of laparoscopic resection in malignant tumors greater than 10 cm. METHODS: We present two cases, a 63 year old woman with a left adrenal heterogeneous mass of 11 cm in maximum diameter and an 80 year old man with a left adrenal heterogeneous mass 13 cm in maximum diameter. In both cases excision was performed laparoscopically using 4 trocars and the Alexis® wound retractor for specimen extraction. RESULTS: For the 63 year old woman, the histological result was malignant epithelioid angiomyolipoma, while in the case of the 80 year old man was large cell neuroendocrine carcinoma with possible pulmonary origin. CONCLUSIONS: We believe that laparoscopic surgery of large masses of malignant behavior depends on the capsular integrity and their relationship to adjacent structures rather than tumor size or the internal characteristics of tumor on imaging tests.

Two staged minimally invasive treatment for acute cholecystitis in high risk patients.

BACKGROUND/AIMS: The most optimal treatment for acute cholecystitis in high risk patients and severe acute cholecystitis remains still controversial. We review the outcomes of a two step treatment with percutaneous cholecystostomy and delayed laparoscopic cholecystectomy (DLC). METHODOLOGY: We collected data prospectively from January 2004 to April 2010 from 26 patients that underwent percutaneous transhepatic CT-guided cholecystostomy and DLC. RESULTS: Percutaneous transhepatic CT-guided cholecystostomy was achieved in all cases with no complications. There was just one catheter dislodgement. Most of patients, 92%, improved after drainage. There was one case of mortality. Laparoscopic cholecystectomy was achieved in 88% of patients with no mortality, and a low rate of morbidity (7.6%) and of conversion to open surgery. Pre-operative percutaneous cholangiogram showed additional and useful information in 55.5% of patients. CONCLUSIONS: Two-step minimally invasive treatment combining percutaneous transhepatic CT-guided cholecystostomy and DLC is safe and feasible and report low morbi-mortality rates.

Laparoscopic splenectomy in the management of benign and malignant hematologic diseases.

OBJECTIVES: The use of laparoscopy to treat malignant hematological diseases is not completely accepted. Our aim was to analyze operative and postoperative results of laparoscopic splenectomy performed for benign versus malignant hematological disorders. METHODS: Between 1994 and 2003, 76 consecutive patients underwent laparoscopic splenectomy. The first 38 cases were performed by using an anterior approach, whereas in the remaining 38 cases a semilateral position was used. RESULTS: Baseline characteristics showed that patients with malignant diseases were significantly older (56.9 vs 32.6 years, P < 0.001). Seventy-two (94.7%) procedures were completed laparoscopically. Conversion was required in 4 cases (5.2%). Mean operative time was 138.5 minutes for benign and 151.0 minutes for malignant diseases, (P > 0.05, ns). The hand-assisted technique was used in 3 patients with massive splenomegaly. Pathologic features showed that spleen volume was higher in patients with malignant diseases (mean interpole diameter 18.1 cm vs 13.7 cm, P < 0.001). Massive splenomegaly (interpole diameter over 20 cm, weight over 1000 g) was present in 13 patients (17.1%); 9 had malignant diseases. Overall perioperative mortality was 1.3% and major postoperative complications occurred in 6 patients (7.8%). Postoperative splenoportal partial thrombosis was identified in 9.7% of patients. CONCLUSIONS: Laparoscopic splenectomy is a well-accepted, less-invasive procedure for hematological disorders. Neoplastic diseases or splenomegaly, or both, do not seem to limit the indications for a minimally invasive approach after the learning curve.

Laparoscopic splenectomy: multi-detector row CT for preoperative evaluation.

PURPOSE: To prospectively evaluate multi-detector row spiral computed tomography (CT) for determination of splenic volume, splenic vascular anatomy, and presence of accessory spleens and parenchymal lesions in patients who were undergoing laparoscopic splenectomy. MATERIALS AND METHODS: Twenty-two patients who were candidates for laparoscopic splenectomy underwent multiphasic multi-detector row CT. Two observers evaluated splenic volume with two hand-tracing editing modalities. Variability between the two observers was calculated with a reliability coefficient (Cronbach alpha). A linear regression equation for each modality was generated to identify the correlation between the two observers. Multi-detector row CT angiography was evaluated for assessment of splenic vascular anatomy. Presence and number of both accessory spleens and parenchymal lesions were recorded. RESULTS: Mean splenic volume was 1,050 and 1,046 mL, respectively, for observers A and B by using each-section editing (technique 1) and 1,067 and 1,068 mL for observers A and B by using distanced editing (technique 2). For each editing modality, alpha reliability coefficient was higher than 0.99. Both techniques 1 and 2 were very highly predictive of specimen weight and had R2 values of greater than 0.99 (P <.001). CT angiograms correctly showed polar arteries in all cases and the presence of the arteria pancreatica magna in one case. Multi-detector row CT demonstrated the presence, number, and size of all accessory spleens and of focal parenchymal lesions. CONCLUSION: Multi-detector row CT volumetric and anatomic evaluation provided accurate and reproducible information.

Accuracy of laparoscopy in the diagnosis and staging of lymphoproliferative diseases.

Laparoscopy seems to be playing an emerging role in the management of lymphoproliferative diseases. The aim of this study was to prospectively analyze personal experience evaluating the role and limits of laparoscopy in the management of lymphomas. From July 1993 to December 2000, 131 consecutive patients were referred to our institution for primary diagnosis (group A, n = 70), suspected relapse (reassessment) (group B, n = 54), or staging/restaging of lymphoproliferative diseases (group C, n = 7). Diagnostic and/or operative laparoscopy was performed in all patients. To assess the accuracy of laparoscopy, the results were analyzed according to the indications for surgery. In all, 128 procedures were completed laparoscopically (95.5%). Conversion was required in 7 cases (5.1%). Causes of the conversions were severe obesity (body mass index 62.5), uncontrolled intraoperative bleeding (HIV+), nondiagnostic tissue sampling (2 cases), perisplenic inflammation and perisplenic abscesses (3 cases). The results of this study highlight the safety of diagnostic and staging laparoscopy and laparoscopic splenectomy in patients with lymphoproliferative diseases (major complications 2.9%, perioperative mortality 0%). In all, 96.4% of patients from group A and 100% of patients from group B were treated on the basis of laparoscopic findings. No false negative diagnosis occurred. Laparoscopy may become the "gold standard" in the management of lymphoproliferative disease in the following settings: for the differential diagnosis of hepatic and/or splenic focal lesions; when percutaneous needle biopsy fails and/or genetic analysis is needed for therapeutic decision; for the primary diagnosis and abdominal staging of patients with diffuse retroperitoneal lymphadenopathy in the absence of peripheral lymphadenopathy; for cases of abdominal restaging after concurrent chemoradiotherapy and in cases of suspected relapse when percutaneous biopsy is not technically possible; and for patients with lymphoproliferative disease when splenectomy is required. Marked splenomegaly with perisplenic inflammatory reaction and lymphadenopathy in HIV+ patients should be considered possible causes of failure of the laparoscopic approach.

[Laparoscopic splenectomy: analysis of 60 consecutive cases]. / La splenectomia laparoscopica: analisi di 60 casi consecutivi.

The purpose of the study was to analyze the results of 60 patients who were candidates for laparoscopic splenectomy. Over the period from May 1994 to May 2001, 60 patients were candidates for splenectomy. Laparoscopy was contraindicated in 3 cases because of ASA III and marked splenomegaly (2 cases) and previous gastric resection (1 case). The procedure was indicated for benign disease in 38 cases and for malignant disease in the remainder. Fifty-three procedures were completed laparoscopically (92.9%). Conversion proved necessary in 4 patients (6.7%) due to large incisional hernia, perisplenic abscess, bleeding of major splenic vessels at the hilum and marked splenomegaly (2 cases of lymphoma). The mean operative time was 200 min for the malignancies and 110 min for the benign conditions (P < 0.05). Major morbidity occurred in 5 cases (8.7%). No deaths were registered. The mean postoperative hospital stay was 7.5 days for patients with malignancies and 5.2 days for patients with benign disease (P < 0.05). Laparoscopic splenectomy was safe and effective in patients with benign disease, even in cases of marked splenomegaly. The morbidity rate was significantly higher in lymphoma patients than in patients with benign haematological disorders.
