Putative predictive parameters for the outcome of laparoscopic splenectomy: a multicenter analysis performed on the Italian Registry of Laparoscopic Surgery of the Spleen.

OBJECTIVE: To identify predictive risk factors for conversion to open splenectomy and postoperative complications in patients undergoing elective laparoscopic splenectomy. BACKGROUND: The laparoscopic approach represents the "gold standard" for splenectomy, but its use in the treatment of splenomegaly and malignant disease is controversial. Factors that influence immediate outcome are clinical, anatomic, and pathologic. METHODS: Univariate and multivariate analyses of data from the Italian Registry of Laparoscopic Surgery of the Spleen, a multicenter database supported by 25 referral centers. Analysis of data (1993-2007) was performed on a series of patients (n = 676) undergoing elective laparoscopic splenectomy. Demographic data, the operative indications, the surgical technique applied, and any intra- and/or postoperative complications with respect to the patients were assessed. Records were analyzed retrospectively using the Student t test, the chi test, and logistic regression. RESULTS: Conversion to open splenectomy was necessary in 39 cases (5.8%). Perioperative deaths occurred in 3 cases (0.4%). There were no complications in 560 patients (82.8%), with a mean hospital stay of 5 days (range, 2-54). Overall, morbidity occurred in 116 patients (17.2%). Multivariate analysis found that the body mass index (P = 0.01) and the presence of hematologic malignancy (P < 0.001) were independent predictors for intraoperative complications and surgical conversion. Spleen longitudinal diameter (P = 0.001) and surgical conversion (P = 0.001) were independent predictors for the occurrence of postoperative complications. CONCLUSIONS: This large multicenter study provides evidence for the significance of predictive risk factors for intra- and postoperative complications in laparoscopic splenic surgery. Besides splenic dimensions, other factors like the patient's habitus and the specific underlying hematologic pathology should be recognized by the surgeon to reduce complications and initiate adequate treatment.

Laparoscopic lymph node biopsy in intra-abdominal lymphoma: high diagnostic accuracy achieved with a minimally invasive procedure.

Ultrasound or computed tomography-guided percutaneous lymph nodes biopsy often do not supply sufficient tissue for the histopathologic diagnosis of a lymphoma. Laparoscopic lymph node biopsy (LLB) has the advantage of obtaining the entire lymph node and avoiding the invasivity and all the possible complications of a laparotomy. The aim of the present study is to assess the safety and diagnostic accuracy of the LLB in intra-abdominal lymphoma. Between April 1999 and October 2005, 36 LLB were performed in 35 patients to rule out or to follow the progression of a lymphoma. The clinical outcome and the pathology reports were analyzed retrospectively. A conversion to laparotomy was necessary in 2 cases due to intraoperative difficulties (5.8%). No major postoperative complications or mortality occurred. Mean hospital stay was 2.1 days. In 9 patients, LLB was performed to follow a possible progression of the lymphoma, whereas in 26 patients it was used to establish a diagnosis. Two repeated LLB were necessary to achieve a correct diagnosis in 1 patient. Fourteen patients had non-Hodgkin lymphoma, 6 patients had Hodgkin lymphoma, 9 patients presented an infiltration by primitive or metastatic tumors, and 7 patients had benign lymphadenopathy. In 97% of the cases, LLB supplied the necessary information for the correct diagnosis, classification, and subsequent therapeutic decisions. In conclusion, LLB is a safe and effective procedure. Its diagnostic accuracy is superior to percutaneous techniques. LLB can be proposed as the procedure of choice to sample deep lymphatic tissues in patients with intra-abdominal lymphadenopathy at a very low morbidity rate and as an outpatient procedure in selected cases.

The Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS) A retrospective review of 379 patients undergoing laparoscopic splenectomy.

In December 2000, the Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS) was formally launched under the auspices of the Italian Society for Endoscopic Surgery and New Technologies (SICE). The aim of this multicentre study was to analyse various aspects of the treatment that are still under discussion, such as the extension of the laparoscopic indications in cases of malignancy, independently of the associated splenomegaly, patient selection and operative techniques. A retrospective review of 379 patients undergoing laparoscopic splenectomy for haematological diseases from February 1, 1993, to September 15, 2005, was conducted. Data were collected from the 18 italian centres participating in the IRLSS. The mean length of surgery was 140 minutes (range: 25-420). Conversion was necessary in 25 cases (6.6%), and at least one accessory spleen was found in 30 patients (8%). The mean spleen weight was 1200 g (range: 85-4500). Perioperative death occurred in two cases (0.5%). There were no complications in 312 patients (82.3%), with a mean hospital stay of 5.5 days (range: 2-30). Morbidity occurred in 67 patients (17.8%), mainly consisting in transient fever (n = 22), pleural effusions (n = 16), and actual or suspected haemorrhage (n = 14), requiring re-intervention in 7 patients. This first study carried out on the IRLSS data shows that laparoscopic splenectomy may constitute the gold standard for haematological diseases with a normal-sized spleen. The low morbidity and mortality rates suggest that laparoscopic splenectomy can be successfully proposed also for splenomegaly in haematological malignancies.

Composite mesh repair of a large paraesophageal hiatal hernia.

We describe the first experience in Italy with a new pre-cut composite polytetrafluoroethylene (PTFE)/expanded PTFE (ePTFE) prosthesis designed for the hiatal region. A 78-year-old female patient with a large paraesophageal hiatal hernia with migration of the left transverse colon inside the hiatal defect (type IV hernia) received laparoscopic repair by means of the composite V-shaped mesh. The procedure was completed laparoscopically and a partial fundoplication was performed. A favorable outcome was assessed by barium swallow radiograms performed on postoperative day 7. A complete resolution of the symptoms was noted at follow-up 1 month postoperatively. This report confirms the feasibility, effectiveness, and added advantages of the composite V-shaped mesh in tension-free repair of a large hiatal hernia.

Minimal-access splenectomy: a viable alternative to laparoscopic splenectomy in massive splenomegaly.

BACKGROUND: Laparoscopic splenectomy of normal-sized spleens or in moderate splenomegaly is performed with increasing frequency. By using a modification of the open laparotomy, minimal-access splenectomy is an attractive alternative in severe splenomegaly. METHODS: Between September 2002 and October 2003, 9 patients (mean age, 58.8 years; range, 41 to 72) with severe splenomegaly (mean length, 27.9 cm; range, 23 to 32) underwent minimal-access splenectomy. Indications for splenectomy were non-Hodgkin's lymphoma in 5 cases and idiopathic myelofibrosis in 4. RESULTS: Minimal-access splenectomy was successfully completed in all patients. Mean operative time was 124 minutes (range, 75 to 165). Postoperative complications occurred in 2 cases; one perioperative death occurred in a patient with idiopathic myelofibrosis as a consequence of a secondary blast crisis. Median postoperative hospital stay was 9.1 days (range, 6 to 15). CONCLUSIONS: Minimal-access splenectomy seems to be a viable alternative to laparoscopic splenectomy in cases of severe splenomegaly. It combines the advantages of hand assistance like shorter operative times and increased safety of the procedure to the classical benefits of minimally invasive surgery.

Laparoscopic tension-free repair of large paraesophageal hiatal hernias with a composite A-shaped mesh: two-year follow-up.

BACKGROUND: Surgical repair of large hiatal hernias is associated with a high recurrence rate when the repair is made by simple cruroplasty. The use of a mesh goes from a reinforcement of a simple cruroplasty to a tension-free repair. We discuss the evolution of this approach and evaluate the outcomes of 27 patients with type II (n = 9), type III (n = 16), and type IV (n = 2) hiatal hernias treated laparoscopically. METHODS: Between November 1999 and October 2003, 27 patients (18 women and 9 men) received laparoscopic repair of large hiatal hernias by means of an A-shaped polypropylene-polytetrafluoroethylene mesh. A total or a partial fundoplication was associated in all cases. The mean age was 60.1 years (range, 36-76 years). The patients presented with symptoms of 2 months to 10 years in duration. Preoperative assessment included an upper gastrointestinal endoscopy, esophageal manometry, 24 hour pH monitoring, and barium swallow. Concomitant esophagitis was found in 16 patients and impaired esophageal peristalsis in 2 patients. Four patients had concomitant gallbladder disease treated at the same time. RESULTS: No conversions occurred in our series. There was no perioperative mortality, and morbidity was low. Follow-up averaged 27 months (range, 6-46 months). There has been 1 recurrence (3.7%), prolonged dysphagia in 4 cases, and no mesh erosion. CONCLUSION: Early results confirm the feasibility of the tension-free repair of large hiatal hernias and the effectiveness of the composite A-shaped mesh. Long-term follow-up for all patients is necessary to determine the real incidence of recurrence.

Outcome of laparoscopic splenectomy for malignant hematologic diseases.

AIM: The role of laparoscopic splenectomy in the treatment of hematological diseases is still controversial. The aim of this study was to assess whether the benign or malignant nature of hematological diseases may influence the outcome of laparoscopic splenectomy. PATIENTS AND METHODS: Between August 1997 and March 2002, 63 unselected patients with hematologic diseases underwent a laparoscopic splenectomy. Patients were divided into two groups according to the benign (Group A, 38 patients) or malignant (Group B, 25 patients) nature of the hematological diseases. RESULTS: Patients in group B were significantly (a) older, (b) had larger spleens that more frequently needed accessory incisions for specimen retrieval, (c) had greater transfusion requirements, and (d) were fed later than patients in group A. There were no statistically significant differences among the two groups in terms of (a) body-mass index, (b) operative time, (c) conversion rate, (d) blood loss, (e) pain medication requirements, and (f) hospital stay. Two postoperative deaths occurred among patients in group B, but none of them was related to surgery. CONCLUSIONS: The results of the study showed that: a) the nature of the disease does not influence the outcome of laparoscopic splenectomy, b) the size of the spleen might increase the risk of conversion, but it is no longer a contraindication to laparoscopic splenectomy, and c) laparoscopic splenectomy can be effectively performed in the treatment of malignant hematologic diseases.

[Role of laparoscopic biopsy in the management of intra-abdominal lymphadenopathy]. / Ruolo della biopsia laparoscopica nella gestione delle linfadenomegalie intraddominali.

Intra- or retroperitoneal lymphadenopathy is often a diagnostic challenge Surgical radiology techniques, such as fine needle aspiration and core needle biopsy, are useful but frequently inadequate and sometimes difficult and dangerous to perform. Deep abdominal lymph node sampling can be done laparoscopically, avoiding the risks of a large laparotomy. The objective of this study was to assess the safety, efficacy and diagnostic accuracy of laparoscopic biopsy, when compared with historic needle biopsy studies reported in the literature. From January 1999 to June 2001, 19 laparoscopic biopsies were performed for 18 patients with intra- or retroperitoneal lymphadenopathy. Clinical and technical characteristics and histopathological findings for each laparoscopic biopsy performed were analysed retrospectively. In 15 patients the biopsy was performed in order to achieve the diagnosis. In the other 4 cases laparoscopic biopsy was required to confirm a relapse or the evolution of a lymphoma during treatment or follow-up. The conversion rate was nil. There were no major complications. None of the patients died postoperatively. The average hospital stay was 2.4 days (range: 1-6 days). In 94% of the cases, the laparoscopic biopsy supplied the necessary information for the correct diagnosis and consequent therapeutic decisions. These results confirm that laparoscopic biopsy is safe and effective. This procedure has a higher diagnostic yield than the percutaneous techniques and should be proposed as the gold standard biopsy approach in all cases of deep abdominal lymphadenopathy.

Laparoscopic bilateral hand-assisted nephrectomy: end-stage renal disease from tuberculosis, an unusual indication for nephrectomy before transplantation.

The purpose of the study was to sterilize renal tuberculous foci in a pretransplantation patient with a laparoscopic hand-assisted approach and to verify the feasibility of bilateral nephrectomy for this indication. This case report is the first description of hand-assisted laparoscopic bilateral nephrectomy for this pathologic condition. The 33-year-old patient had end-stage renal disease from renal tuberculosis. A commercially available hand-assistance device was used through a midline 8-cm supraumbilical incision and with four ports. The procedure was successfully completed. The total operative time was 3 hours and 40 minutes. Estimated blood loss was 250 mL. The postoperative course was uneventful, and clinical follow-up at 3 weeks revealed a successful outcome. Hand-assisted bilateral laparoscopic nephrectomy in patients with chronic renal failure from tuberculosis represents a viable option because it is feasible and effective. The hand-assisted approach increases the safety of the procedure while retaining all the advantages of minimally invasive surgery.
