CONTEXT: Symptomatic lymphocele (sLC) occurs at a frequency of 2-10% after robot-assisted radical prostatectomy (RARP) with pelvic lymph node dissection (PLND). Construction of bilateral peritoneal interposition flaps (PIFs) subsequent to completion of RARP + PLND has been introduced to reduce the risk of lymphocele, and was initially evaluated on the basis of retrospective studies. OBJECTIVE: To conduct a systematic review and meta-analysis of only randomized controlled trials (RCTs) evaluating the impact of PIF on the rate of sLC (primary endpoint) and of overall lymphocele (oLC) and Clavien-Dindo grade ≥3 complications (secondary endpoints) to provide the best available evidence. EVIDENCE ACQUISITION: In accordance with the Preferred Reporting Items for Meta-Analyses statement for observational studies in epidemiology, a systematic literature search using the MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE databases up to February 3, 2023 was performed to identify RCTs. The risk of bias (RoB) was assessed using the revised Cochrane RoB tool for randomized trials. Meta-analysis used random-effect models to examine the impact of PIF on the primary and secondary endpoints. EVIDENCE SYNTHESIS: Four RCTs comparing outcomes for patients undergoing RARP + PLND with or without PIF were identified: PIANOFORTE, PerFix, ProLy, and PLUS. PIF was associated with odds ratios of 0.46 (95% confidence interval [CI] 0.23-0.93) for sLC, 0.51 (95% CI 0.38-0.68) for oLC, and 0.41 (95% CI 0.21-0.83) for Clavien-Dindo grade ≥3 complications. Functional impairment resulting from PIF construction was not observed. Heterogeneity was low to moderate, and RoB was low. CONCLUSIONS: PIF should be performed in patients undergoing RARP and simultaneous PLND to prevent or reduce postoperative sLC. PATIENT SUMMARY: A significant proportion of patients undergoing prostate cancer surgery have regional lymph nodes removed. This part of the surgery is associated with a risk of postoperative lymph collections (lymphocele). The risk of lymphocele can be halved via a complication-free surgical modification called a peritoneal interposition flap.

BACKGROUND: Symptomatic lymphoceles present the most common complication of robot-assisted radical prostatectomy (RARP) with extended pelvic lymph node dissection (ePLND). No surgical technique has so far shown success in reducing the incidence rate, but several retrospective studies have shown the beneficial effect of the fixation of the peritoneum. OBJECTIVE: To introduce a modification in the technique of fixing the peritoneum to the pubic bone and to confirm whether this intervention reduces the incidence of lymphoceles. DESIGN, SETTING, AND PARTICIPANTS: A prospective randomized (1:1) single-center one-sided blind study was conducted in patients with localized prostate cancer (cT1-2cN0M0) indicated for RARP with ePLND operated between December 2019 and June 2021. In the intervention group, the free flap of the peritoneum was fixed to the pubic bone. In the control group, the peritoneal flap was left free without fixation. SURGICAL PROCEDURE: In the intervention group, the free flap of the peritoneum was fixed to the pubic bone (PerFix) so that lateral holes were left, allowing drainage of lymph from the pelvis into the abdominal cavity, where it would be resorbed. The iliac vessels and obturator fossa remained uncovered by the peritoneum and the bladder. MEASUREMENTS: The primary objective was to evaluate the frequency of symptomatic lymphoceles during follow-up. The secondary endpoints were the radiological presence of lymphoceles on computed tomography of the pelvis carried out 6 wk after surgery, the volume of the lymphoceles, and the degree of severe (Clavien-Dindo ≥3) complications. RESULTS AND LIMITATIONS: Of the 260 randomized patients, 245 were evaluated in the final analysis-123 in the intervention and 122 in the control group. The median follow-up was 595 d. There were no differences between the groups regarding clinical and pathological variables. The median of 17 nodes removed was the same in both groups (p = 0.961). Symptomatic lymphoceles occurred in 17 patients (6.9%), while in the intervention group these were found in three (2.4%) versus 14 (11.5%) in the control group (p = 0.011). The number of radiologically detected asymptomatic lymphoceles did not differ (p = 0.095). There was no significant difference in lymphocele volume between the two groups (p = 0.118). The rate of serious complications (Clavien 3a and 3b) was 4.8% in the intervention group and 9.1% in the control group (p = 0.587). A multivariate logistic regression model of symptomatic lymphocele occurrence was created with significant factors: body mass index (odds ratio [OR] = 1.1, 95% confidence interval [CI] = [1.03, 1.26], p = 0.012) and intervention (OR = 4.6, 95% CI = [1.28, 16.82], p = 0.02). CONCLUSIONS: Fixation of the peritoneum (PerFix) reduced the incidence of symptomatic lymphoceles in RARP with ePLND. We found no difference in the frequency of asymptomatic lymphocele development. The volume of the detected lymphoceles was similar. PATIENT SUMMARY: In this study, we compared the rate of development of postoperative complications using the peritoneal fixation technique with that of a nonfixation control group for robot-assisted radical prostatectomy with extended pelvic lymphadenectomy. Fixation of the peritoneum should obviate the development of severe complications in the postoperative period.

BACKGROUND: An ocular adnexal apocrine adenocarcinoma (OAAA) is an extremely rare, but potentially aggressive and life-threatening tumor with ill-defined management based only on recommendations from a limited number of reported cases. The development of cervical lymphocele following neck dissection is a very rare complication, but one with well established methods for prevention and treatment. Here we describe a previously unreported case of salvage surgery including neck dissection for OAAA in addition to an emergence of cervical lymphocele. A literature review of current knowledge on both pathological conditions is included. METHODS AND RESULTS: A 58-year-old man suffering from OAAA, previously treated with multiple eye-sparing excisions and adjuvant proton therapy, underwent salvage surgery for locoregional recurrence of the tumor. A partial orbitectomy with orbital exenteration, primary reconstruction and left-sided neck dissection was performed. The procedure was complicated by a cervical lymphocele resolved after the surgical therapy. The patient remained disease-free during the one-year follow-up. CONCLUSION: OAAA is a locally aggressive tumor with potential to local or distant metastatic spread. Whole-body staging, regular clinico-radiological follow-up and stage-dependent therapy with surgery as the first-choice treatment is required. A cervical lymphocele as a complication of especially left-sided neck dissection is managed with a conservative or surgical therapy according to the level of lymph leakage, extent and localization of lesions, presence of local or systemic disorders and the period from primary surgery.

Radikální prostatektomie (RP) s rozšířenou pánevní lymfadenektomií (ePLND) představuje standardní terapii středně a vysoce rizikového lokalizovaného karcinomu prostaty (PCa). Využití ePLND v poslední době narůstá díky provádění většího množství RP u agresivnějších nádorů. Jednou z častých komplikací této operace je vznik symptomatických lymfokél, který se udává až u 10 % operovaných. Dosud, i přes rozsáhlý výzkum, nebyla nalezena vhodná strategie, jak předejít této komplikaci. Jednou z potenciálně úspěšných intervencí se zdá být fixace volného listu peritonea při provádění transperitoneální RP. Několik retrospektivních klinických studií prokázalo snížení výskytu symptomatických lymfokél při fixování peritonea k měchýři nebo stěně pánve, čímž je ponechána mezera v peritoneu, která vytvoří cestu pro volný pohyb lymfy z pánevní oblasti do peritoneální dutiny a její následnou resorpci. Jediná dosud publikovaná randomizovaná studie však tuto hypotézu nepotvrdila. Cílem tohoto článku je představit přehled dosud publikovaných klinických studií zabývajících se fixací peritonea.
Radical prostatectomy (RP) with extended pelvic lymph node dissection (ePLND) is currently a standard of care of intermediate and high-risk localized prostate cancer (PCa). The utilization of ePLND is increasing due to stage migration towards more aggressive cancer. Symptomatic lymphoceles, with incidence ranging up to 10 %, are one of the most frequent complications of ePLND. No successful strategy on how to prevent their occurrence has been found so far. One of the promising interventions could be peritoneal flap fixation during transperitoneal RP. Several retrospective studies have shown a reduction in the incidence of symptomatic lymphocele. The peritoneum can be fixed to the urinary bladder or to the pelvic wall leaving a window in the peritoneum that presents a pathway that directs the lymphatic fluid out of the pelvis into the peritoneal cavity where it can be absorbed. The only randomized trial published so far, however, did not show any benefit. This article aims to present an overview of published clinical studies on the fixation of the peritoneum.

The aim of the study was to evaluate the role of colloid osmotic pressure in post-transplant lymphocele pathogenesis. We have analyzed total plasmatic protein and albumin levels, and electrophoresis has been completed in blood samples before transplantation and in days 3 and 14 after transplantation in 50 patients with lymphocele (Lymphocele) and 198 patients without lymphocele (control), respectively. Colloid osmotic pressure (COP) was calculated according to the Hoefs formula. Statistically significant differences were confirmed in albumin levels (42.2 respectively 44.8 g/L) before transplantation (day 0); in total protein (52.5 resp. 55.5 g/L), in albumin (30.1 resp. 32.1 g/L), and COP (15.6 respectively 17.7 kPa) in day 3; and in total protein (52.8 resp. 58.9 g/L), in albumin (30.5 respectively 35.4 g/L), in COP (16.1 respectively 21.2 kPa) in day 14. A potentially critical albumin level was established in 44.1 g/L in the blood analyzed, but its sensitivity was only 62%. The main risk element for the lymphocele formation remains the surgeon's hand. We can proclaim the role of proteins and their COP in the post-transplant lymphocele formation as one of possible pathogenetic cofactors. It is responsible for the impaired mechanisms of the reabsorption the lymph back to the tissues. Better metabolic care could help to reduce incidence of this surgical complication.

OBJECTIVE: To evaluate the efficacy of a collagen-fibrin patch for the prevention of symptomatic lymphoceles after pelvic lymphadenectomy in women with gynecologic malignancies. METHODS: In a multicenter, randomized, clinical trial, 164 women with pelvic lymphadenectomy were allocated either to bilateral pelvic application of two collagen-fibrin patches or no intervention. Main outcome was efficacy, defined as reduction of symptomatic lymphocele rate diagnosed within four weeks after surgery. Secondary outcomes were asymptomatic lymphoceles and subsequent interventions. Sample size was based on the assumption that application of a collagen-fibrin patch reduces the prevalence of symptomatic lymphoceles by at least 66%. The study was single-blinded, i.e., patients and primary outcome assessors, but not surgeons, were blinded to the treatment allocation. RESULTS: A total of 75 women were randomized to the intervention and 89 to the control group. All women received the allocated intervention. In total, 42 (27.4%) lymphoceles and 8 (5.2%) symptomatic lymphoceles were observed. Symptomatic lymphoceles were observed in 5/68 (7.4%) women in the intervention group and 3/85 (3.5%) women in the control group (p = 0.47). Asymptomatic lymphoceles were observed in 16 (23.5%) women in the intervention group compared to 18 (21.2%) in the control group (p = 0.85). In a multivariate logistic regression model, no independent risk factor for the development of a symptomatic lymphocele was ascertained. DISCUSSION: Intraoperative application of collagen-fibrin patches to the pelvic side walls does not reduce the incidence of symptomatic lymphoceles in women with gynecologic malignancies undergoing pelvic lymphadenectomy.

A lymphocele is a cystic mass that may occur in the retroperitoneum following a systematic pelvic and/or para-aortic lymphadenectomy. Lymphoceles may be the cause of severe morbidity, or rarely mortality. Symptomatic lymphoceles manifest with pain, compression of adjacent structures, lymphoedema, deep vein thrombosis or inflammation. The morbidity associated with a symptomatic lymphocele may reduce the quality of life of a patient, as well as delay subsequent cancer treatment. The number and positivity of removed lymph nodes, surgical approach, type of tumor, radiotherapy and BMI rate are among the most discussed risk factors of lymphocele formation. The incidence of postoperative lymphocele is reported in the broad range of 1-58%; 5-18% of those who are symptomatic. Only symptomatic lymphoceles should be treated. Mini-invasive methods involving catheter drainage and sclerotization tend to prevail. Surgery either via laparoscopy or laparotomy remains an option in recurring, poorly accessible or inflammatory lymphoceles.

Autor retrospektivně vyhodnocuje časné urologické komplikace u 360 transplantací ledvin provedených v letech 1998–2008 na Urologické klinice Fakultní nemocnice Olomouc. U jednotlivých druhů komplikací nabízí obecné možnosti řešení, které pak specifikuje na metody užívané transplantačním centrem. Nejvýznamnějšími urologickými komplikacemi byla močová píštěl (6/360, 1,7 %), obstrukce ureterovezikální anastomózy (7/360, 1,9 %) a lymfokéla (6/360, 1,7 %). Bylo zaznamenáno celkem 19 urologických komplikací (19/360, 5,3 %). Operační tým Fakultní nemocnice Olomouc tvoří lékaři Urologické kliniky a cévní chirurgové II. chirurgické kliniky LF UP a FN. Stabilní účast urologů v operační skupině významně snižuje množství urologických komplikací.
The author retrospectively evaluates early urological complications in 360 kidney transplantations performed between the years 1998 and 2008 at the Department of Urology, Olomouc University Hospital. General management options are discussed for individual types of complications which are then specified by the methods used in the transplantation centre. The most significant urological complications included urinary fistula (6/360, 1.7 %), obstruction of the ureterovesical anastomosis (7/360, 1.9 %) and lymphocele (6/360, 1.7 %). A total of 19 urological complications were noted (19/360, 5.3 %). The Olomouc University Hospital operating team consists of physicians of the Department of Urology and vascular surgeons of the II. Dpt. of Surgery. The consistent participation of urologists in the operating team significantly reduces the rate of urological complications.
Přibližně 20 % lymfokél po transplantaci ledviny je symptomatických a vyžadují léčbu. Správná indikace k léčbě a vhodně zvolená technika dokáže ochránit transplantovanou ledvinu před komplikacemi lymfokély. Možností léčby je široká škála od neinvazivních až po operační. Z miniinvazivních technik je nejčastěji používaná sklerotizace. Metodou volby chirurgického řešení lymfokély je laparoskopická drenáž do peritoneální dutiny. Správně léčená lymfokéla neovlivňuje funkci transplantované ledviny dokonce ani z dlouhodobého hlediska.
About 20% of post-transplant lymphoceles are symptomatic and require treatment. Correct treatment indication and accurate treatment approach could ensure the transplanted kidney from lymphocele complications. There is wide scale of treatment modalities from noninvasive to surgical procedures. The most frequently used miniinvasive procedure is sclerotisation. The first choice surgical method is a laparoscopic drainage of the lymphocele into the peritoneal cavity. Correctly treated lymphocele does not impair graft function even in long-term follow-up.
