Laparoscopic splenectomy for hematological diseases

BackgroundWe reviewed retrospectively the records of all patients who underwent laparoscopic splenectomy (LS) at our institution for a wide range of hematological disorders. We compared our experience to those reported in the literature and analyzed various aspects of the treatment that are still under discussion and in need of confirmation, such as the treatment of malignant blood diseases, the indication in case of splenomegaly, and the adequacy of the detection of accessory spleens.MethodsBetween June 1997 and June 2001, we performed 43 LS. The patients were classified into three groups according to clinical diagnosis: idiopathic thrombocytopenic purpura (ITP) (n=23), hemolytic anemia (HA) (n=5) and hematological malignancy (HM) (n=15). Statistical analyses were done to compare the three groups.ResultsLS was completed in 41 patients, with a conversion rate of 5%. Splenomegaly was present in 37% of all patients (73% of HM). Mean operative time was 128 min. The incidence of accessory spleens was 20%. A concomitant laparoscopic procedure was done in three cases (cholecystectomy). Postoperative complications occurred in eight patients (18%). Duration of surgery, length of hospital stay, transfusions rate, and some demographics features, such as age and spleen weight and length, were significantly different in each group. No deaths were attributed to the procedure.ConclusionsThe statistical analysis of our series shows that, the laparoscopic approach reliable even in the management of malignant and nonmalignant blood diseases.

Sister Joseph's nodule in a liver transplant recipient: Case report and mini-review of literature

BackgroundUmbilical metastasis is one of the main characteristic signs of extensive neoplastic disease and is universally referred to as Sister Mary Josephs nodule.Case presentationA 59-years-old Caucasian female underwent liver transplant for end stage liver disease due to hepatitis C with whole graft from cadaveric donor in 2003. After transplantation the patient developed multiple subcutaneous nodules in the umbilical region and bilateral inguinal lymphadenopathy. The excision biopsy of the umbilical mass showed the features of a poorly differentiated papillary serous cystadenocarcinoma. Computed tomographic scan and transvaginal ultrasonography were unable to demonstrate any primary lesion. Chemotherapy was start and the dosage of the immunosuppressive drugs was reduced. To date the patient is doing well and liver function is normal.ConclusionsThe umbilical metastasis can arise from many sites. In some cases, primary tumor may be not identified; nonetheless chemotherapy must be administrated based on patients history, anatomical and histological findings.

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.

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.
