Single-Port vs. Conventional Multi-Port Laparoscopic Lymph Node Biopsy (original) (raw)

2020, JSLS : Journal of the Society of Laparoscopic & Robotic Surgeons

Background and Objectives:The purpose of the investigation was to compare clinical results and diagnostic accuracy for conventional multiport laparoscopic lymph node biopsy (MPLB) and single-port laparoscopic lymph node biopsy (SPLB) operations at a single institution.Methods:A set of 20 SPLB patients operated on from October 2016 to May 2019 were compared to an historical series of 35 MPLB patients. Primary endpoints were the time of surgery, estimated blood loss, surgical conversion, length of stay and morbidity. The secondary endpoint was the diagnostic accuracy of the technique.Results:SPLB was completed laparoscopically in all cases. Two MPLB patients (5.7%) experienced a surgical conversion due to intraoperative difficulties. Duration of surgery was similar in SPLB and MPLB groups respectively (84 ± 31.7 min vs. 81.1 ± 22.2; P = .455). A shorter duration of hospital stay was shown for patients operated on by SPLB compared to the MPLB group (1.7 ± 0.9 days vs. 2.1 ± 1.2 days; P = .133). The postoperative course was uneventful in both groups. In 95% of the SPLB and 97.1% of the MPLB cases respectively, LLB achieved the necessary information for the diagnosis.Conclusion:SPLB has shown good procedural and postoperative outcomes as well as a high diagnostic yield, comparable to traditional MPLB. Therefore, our results show that this approach is safe and effective and can be an equally valid option to MPLB to obtain a diagnosis or to follow the progression of a lymphoproliferative disease. Further studies are necessary to support these results before its widespread adoption.

An audit to study the diagnostic yield of lymph node biopsies under local anaesthesia

International Surgery Journal

Background: Surgical referrals for lymph node biopsies are common, majority for diagnostic purposes. The indications and the diagnostic yield vary for different sites. We conducted an audit of the lymph node biopsies done over a period of seven months.Methods: The audit included 547 patients who underwent lymph node biopsies under local anesthesia in the department of general surgery over a seven-month period. Parameters such as overall diagnostic yield of lymph node biopsies, disease specific yield of lymph node biopsies with a primary focus on tuberculosis; site specific yield of lymph node biopsies and referral pattern for the request for lymph node biopsies were analysed.Results: 324 samples (59.2%) yielded a definite diagnosis, which included haematological malignancy 102 (31.5%), infectious diseases 131 (40.5%), and 59 (18.5%) malignancy. The diagnostic yield of supraclavicular lymph nodes was found to be highest (72.45%) and the axillary group the lowest (39.8%). The referra...

Histopathological Evaluation of Lymph Node Biopsies: A Hospital Based Study

Journal of Enam Medical College, 2012

Background: Lymphadenopathy is a common manifestation of a large variety of disorders,both benign and malignant. It is essential to define the pattern of disorders presenting primarily as lymph node enlargement in a particular environment. Histopathological examination of the lymph node biopsies is a gold standard test in the distinction between reactive and malignant lymphoid proliferations as well as for detailed subtyping oflymphomas. We designed this study in our population for histopathological evaluation of lymph nodes that might be helpful for clinical management of these lesions. Objective: Histopathological evaluation of lymphadenopathy from excised specimen, in relation to ageand sex of the patients, and distribution of the lymph nodes. Materials and Methods: It was a retrospective cross sectional study conducted in the department of Pathology, Enam MedicalCollege & Hospital, Savar, Dhaka during the period from January 2006 to December 2010. Lymph node biopsies of all pati...

Rapid access clinic for unexplained lymphadenopathy and suspected malignancy: prospective analysis of 1000 patients

BMC hematology, 2018

In patients presenting with peripheral lymphadenopathy, it is critical to effectively identify those with underlying cancer who require urgent specialist care. We analyzed a large dataset of 1000 consecutive patients with unexplained lymphadenopathy referred between 2001 and 2009 to the Royal Marsden Hospital (RMH) rapid access lymph node diagnostic clinic (LNDC). Cancer was diagnosed in 14% of patients. Factors predictive for malignant disease were male sex, age, supraclavicular and multiple site involvement. Cancer-associated symptoms were present for a median of 8 weeks. The median time from referral to start of cancer therapy was 53 days. Fine needle aspiration (FNA) was performed in 83% of patients with malignancies. Sensitivity and specificity of FNA were limited (50 and 87%, respectively for any malignancy; 30 and 79%, respectively for lymphoma). The vast majority of cancer patients received diagnostic biopsies on the basis of suspicious clinical and ultrasound findings; the ...
