Journal of Minimally Invasive Gynecology Feb 2020To conduct a systematic review of the literature on patients with extrapelvic deep endometriosis.
OBJECTIVE
To conduct a systematic review of the literature on patients with extrapelvic deep endometriosis.
DATA SOURCES
A thorough search of the PubMed/Medline, Embase, and Cochrane databases was performed.
METHODS OF STUDY SELECTION
Studies in the last 20 years that reported on primary extrapelvic endometriosis were included (PROSPERO registration number CRD42019125370).
TABULATION, INTEGRATION, AND RESULTS
The initial search identified 5465 articles, and 179 articles, mostly case reports and series, were included. A total of 230 parietal (PE), 43 visceral (VE), 628 thoracic (TE), 6 central nerve system, 12 extrapelvic muscle or nerve, and 1 nasal endometriosis articles were identified. Abdominal endometriosis was divided into PE and VE. PE lesions involved primary lesions of the abdominal wall, groin, and perineum. When present, symptoms included a palpable mass (99%), cyclic pain (71%) and cyclic bleeding (48%). Preoperative clinical suspicion was low, the use of tissue diagnosis was indeterminate (25%), and a few (8%) malignancies were suspected. Surgical treatment for PE included wide local excision (97%), with 5% recurrence and no complications. Patients with VE involving abdominal organs - kidneys, liver, pancreas, and biliary tract - were treated surgically (86%) with both conservative (51%) and radical resection (49%), with 15% recurrence and 2 major complications reported. In patients with TE involving the diaphragm, pleura, and lung, isolated and concomitant lesions occurred and favored the right side (80%). Patients with TE presented with the triad of catamenial pain, pneumothorax, and hemoptysis. Thoracoscopy with resection followed by pleurodesis was the most common procedure performed, with 29% recurrence. Adjuvant medical therapy with gonadotropin-releasing hormone was administered in 15% of cases. Preoperative magnetic resonance imaging was performed in all cases of nonthoracic and nonabdominal endometriosis. Common symptoms were paresthesia and cyclic pain with radiation. Surgical resection was reported in 84%, with improvement of symptoms.
CONCLUSION
Extrapelvic endometriosis, traditionally thought to be rare, has been reported in a considerable number of cases. Heightened awareness and clinical suspicion of the disease and a multidisciplinary approach are recommended to achieve a prompt diagnosis and optimize patient outcomes. Currently, there are no comparative studies to provide recommendations regarding optimal diagnostic methods, treatment options, and outcomes for endometriosis involving extrapelvic sites.

Meta-Analysis Review
OBJECTIVE
Leukaemia is the most common cancer of childhood, accounting for a third of cases. In order to assist clinicians in its early detection, we systematically reviewed all existing data on its clinical presentation and estimated the frequency of signs and symptoms presenting at or prior to diagnosis.
DESIGN
We searched MEDLINE and EMBASE for all studies describing presenting features of leukaemia in children (0-18 years) without date or language restriction, and, when appropriate, meta-analysed data from the included studies.
RESULTS
We screened 12 303 abstracts for eligibility and included 33 studies (n=3084) in the analysis. All were cohort studies without control groups. 95 presenting signs and symptoms were identified and ranked according to frequency. Five features were present in >50% of children: hepatomegaly (64%), splenomegaly (61%), pallor (54%), fever (53%) and bruising (52%). An additional eight features were present in a third to a half of children: recurrent infections (49%), fatigue (46%), limb pain (43%), hepatosplenomegaly (42%), bruising/petechiae (42%), lymphadenopathy (41%), bleeding tendency (38%) and rash (35%). 6% of children were asymptomatic on diagnosis.
CONCLUSIONS
Over 50% of children with leukaemia have palpable livers, palpable spleens, pallor, fever or bruising on diagnosis. Abdominal symptoms such as anorexia, weight loss, abdominal pain and abdominal distension are common. Musculoskeletal symptoms such as limp and joint pain also feature prominently. Children with unexplained illness require a thorough history and focused clinical examination, which should include abdominal palpation, palpation for lymphadenopathy and careful scrutiny of the skin. Occurrence of multiple symptoms and signs should alert clinicians to possible leukaemia.

BACKGROUND
The term "difficult intravenous access" (DIVA) is commonly used but not clearly defined. Repeated attempts at peripheral intravenous catheter (PIVC) insertion can be a traumatic experience for patients, leading to sub-optimal clinical and economic outcomes. We conducted a systematic literature review (SLR) to collate literature definitions of DIVA, with the aim of arriving at an evidence-driven definition.
METHODS
The SLR was designed to identify clinical, cost, and quality of life publications in patients requiring the insertion of a PIVC in any setting, including studies on US-guidance and/or guidewire, and studies with no specific intervention. The search was restricted to English language studies published between 1st January 2010 and 30th July 2020, and the Ovid platform was used to search several electronic databases, in addition to hand searching of clinical trial registries.
RESULTS
About 121 studies were included in the SLR, of which 64 reported on the objectives relevant to this manuscript. Prevalence estimates varied widely from 6% to 87.7% across 19 publications, reflecting differences in definitions used. Of 43 publications which provided a definition of DIVA, six key themes emerged. Of these, themes 1-3 (failed attempts at PIV access using traditional technique; based on physical examination findings for example no visible or palpable veins; and personal history of DIVA) were covered by all but one publication. Following a failed insertion attempt, the most common number of subsequent attempts was 3, and it was frequently reported that a more experienced clinician would attempt to gain access after multiple failed attempts.
CONCLUSIONS
Considering the themes identified, an evidence-driven definition of DIVA is proposed: "when a clinician has two or more failed attempts at PIV access using traditional techniques, physical examination findings are suggestive of DIVA (e.g. no visible or palpable veins) or the patient has a stated or documented history of DIVA."

Review
Review article: Peripheral intravenous catheter insertion in adult patients with difficult intravenous access: A systematic review of assessment instruments, clinical practice guidelines and escalation pathways.
The optimal approach for peripheral intravenous catheter (PIVC) insertion in adult hospitalised patients with difficult intravenous access (DIVA) is unknown. The present study aimed to critically appraise the quality of (i) assessment instruments and (ii) clinical practice guidelines (CPGs) or escalation pathways for identifying and managing patients with DIVA. Cochrane Central Register of Controlled Trials, EBSCO MEDLINE, EMBASE (OVID) and EBSCO CINAHL databases were searched on 22 March 2021. Studies describing a DIVA assessment measure, CPG or escalation pathway for PIVC insertion in adults (≥18 years of age) were included. Data were extracted using a standardised data extraction form including study design, type of resource and reported clinical outcomes. Quality of DIVA assessment instruments were reviewed using the COnsensus-based Standards for the selection of health Measurement Instruments checklist. Methodological quality of CPGs and escalation pathways was assessed using the Appraisal of Guidelines for Research and Evaluation-II (AGREE-II) instrument. Overall, 24 DIVA resources comprising 16 DIVA assessment instruments and nine CPGs or escalation pathways (including one combined assessment instrument and escalation pathway) were identified. Instruments commonly focused on vein visibility and palpability as indicators of DIVA. CPGs and escalation pathways unanimously recommended use of vessel visualisation technology for patients with or suspected of DIVA. Methodological quality of the resources was mixed. Consensus and standardisation of resources to identify DIVA and recommendations for managing patients with DIVA is limited. Adopting consistent, evidence-based CPGs, escalation pathways or DIVA assessment instruments may significantly improve clinical outcomes.

Review
INTRODUCTION
Composite phaeochromocytoma is a tumour containing a separate tumour of neuronal origin in addition to a chromaffin cell tumour. This study reports on two cases from a single centre's records and presents a systematic literature review of composite phaeochromocytomas.
METHODS
In addition to describing 2 case reports, a systematic search of the Medline database from inception up to April 2020 was done for human case reports on composite phaeochromocytomas. Relevant titles and/or abstracts were screened, and full texts were reviewed to identify appropriate studies. Data was extracted and a descriptive analysis of presentation, clinical features, management strategies and outcomes was performed. The quality of included studies was assessed using a critical appraisal checklist.
RESULTS
There were 62 studies included, with a total of 94 patients. Of 91 patients where data was available, the median (range) age of patients was 48 (4-86) years. Of 90 patients where information was provided, 57% were female. In at least 28% of patients, a genetic cause was identified. Common presenting features include abdominal pain, palpable mass, cardiovascular and gastrointestinal symptoms. The most common tumour component with phaeochromocytoma is ganglioneuroma; other components include ganglioneuroblastoma, neuroblastoma and malignant peripheral nerve sheath tumours. In patients with follow-up data (n=48), 85% of patients were alive and well at a median (range) follow-up time of 18 (0.5-168) months.
CONCLUSION
Composite phaeochromocytoma is a rare tumour, with a significant genetic predisposition. This review summarises available epidemiological data, which will be useful for clinicians managing this rare condition.

Meta-Analysis Review
BACKGROUND/PURPOSE
Laparoscopic orchiopexy (LO) was recently described as superior to open orchiopexy (OO) for palpable undescended testes (UDT). We aimed to investigate the outcomes of LO of palpable UDT in relation to high retroperitoneal dissection, Prentiss maneuver and intrascrotal testis fixation; also, to identify evidence for the safety, efficacy and cost of LO compared with OO in palpable UDT.
METHODS
Systematic search was performed for all studies on LO for palpable UDT, and for all comparative studies between LO and OO in palpable UDT. Fisher's test was used to assess associations between success/complications rates and different LO approaches and meta-analysis to compare LO and OO.
RESULTS
In LO, success rates were not affected by regular high dissection (p = 1.0), Prentiss maneuver (p = 1.0) or intrascrotal fixation (p = 1.0); in fact, higher complications rates were noticed with regular high dissection (p = 0.002) and Prentiss maneuver (p = 0.01). Meta-analysis showed no significant differences between LO and OO in success (p = 0.17) and complications (p = 0.14) rates, while LO cost was higher in all comparative studies.
CONCLUSIONS
Evidence shows higher benefit-cost ratio for OO and, therefore, the latter should remain the procedure of choice. LO can be alternatively used, as it shows comparable safety/efficacy, but it should not include high dissection, Prentiss maneuver and testis fixation, when unnecessary.

Review
BACKGROUND
Fat necrosis is a well-known complication of free tissue transfer and fat grafting that is becoming increasingly reported in the literature. However, there is no clear consensus on how fat necrosis is defined and classified in the plastic surgery literature.
METHODS
A systematic review of the literature was performed using the PubMed database of the National Library of Medicine and National Institutes of Health and Google Scholar from January 1, 2003, to November 1, 2013. The keywords used in the search included "fat necrosis" and "plastic surgery."
RESULTS
Sixty-nine articles were chosen that met the authors' criteria and were included in this review. There was wide variation on the size requirements and postoperative timing when defining fat necrosis. In addition, the workup sought after clinical examination to confirm a diagnosis of fat necrosis varied, including radiographic studies, histopathologic examination, or a series of studies.
CONCLUSIONS
Based on the articles reviewed in this article, a more uniform definition needs to exist that is clearly defined in all articles that report on fat necrosis. The authors suggest defining fat necrosis as a palpable, discrete, and persistent subcutaneous firmness found postoperatively that measures at least 1 cm during physical examination. Fat necrosis can be identified and confirmed by imaging and histopathology or through intraoperative findings. The authors provide a classification system for fat necrosis that can be used by clinicians to describe fat necrosis into varying grades of severity to ultimately help guide clinical decision-making.

BACKGROUND
Primary liver tumours and liver metastases from colorectal carcinoma are two of the most common malignant tumours to affect the liver. The liver is second only to the lymph nodes as the most common site for metastatic disease. More than half of the people with metastatic liver disease will die from metastatic complications. Electrocoagulation by diathermy is a method used to destroy tumour tissue, using a high-frequency electric current generating high temperatures, applied locally with an electrode (needle, blade, or ball). The objective of this method is to destroy the tumour completely, if possible, in a single session. With the time, electrocoagulation by diathermy has been replaced by other techniques, but the evidence is unclear.
OBJECTIVES
To assess the beneficial and harmful effects of electrocoagulation by diathermy, administered alone or with another intervention, versus no intervention, other ablation methods, or systemic treatments in people with liver metastases.
SEARCH METHODS
We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE Ovid, Embase Ovid, LILACS, Science Citation Index Expanded, Conference Proceedings Citation Index - Science, CINAHL, ClinicalTrials.gov, ICTRP, and FDA to October 2020.
SELECTION CRITERIA
We considered all randomised trials that assessed beneficial and harmful effects of electrocoagulation by diathermy, administered alone or with another intervention, versus comparators, in people with liver metastases, regardless of the location of the primary tumour.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. We assessed risk of bias of the included trial using predefined risk of bias domains, and presented the review results incorporating the certainty of the evidence using GRADE.
MAIN RESULTS
We included one randomised clinical trial with 306 participants (175 males; 131 females) who had undergone resection of the sigmoid colon, and who had five or more visible and palpable hepatic metastases. The diagnosis was confirmed by histological assessment (biopsy) and by carcinoembryonic antigen (CEA) level. The trial was conducted in Iraq. The age of participants ranged between 38 and 79 years. The participants were randomised to four different study groups. The liver metastases were biopsied and treated (only once) in three of the groups: 75 received electrocoagulation by diathermy alone, 76 received electrocoagulation plus allopurinol, 78 received electrocoagulation plus dimethyl sulphoxide. In the fourth intervention group, 77 participants functioning as controls received a vehicle solution of allopurinol 5 mL 4 x a day by mouth; the metastases were left untouched. The status of the liver and lungs was followed by ultrasound investigations, without the use of a contrast agent. Participants were followed for five years. The analyses are based on per-protocol data only analysing 223 participants. We judged the trial to be at high risk of bias. After excluding 'nonevaluable patients', the groups seemed comparable for baseline characteristics. Mortality due to disease spread at five-year follow-up was 98% in the electrocoagulation group (57/58 evaluable people); 87% in the electrocoagulation plus allopurinol group (46/53 evaluable people); 86% in the electrocoagulation plus dimethyl sulphoxide group (49/57 evaluable people); and 100% in the control group (55/55 evaluable people). We observed no difference in mortality between the electrocoagulation alone group versus the control group (risk ratio (RR) 0.98, 95% confidence interval (CI) 0.94 to 1.03; 113 participants; very low-certainty evidence). We observed lower mortality in the electrocoagulation combined with allopurinol or dimethyl sulphoxide group versus the control group (RR 0.87, 95% CI 0.80 to 0.95; 165 participants; low-certainty evidence). We are very uncertain regarding post-operative deaths between the electrocoagulation alone group versus the control group (RR 1.03, 95% CI 0.07 to 16.12; 152 participants; very low-certainty evidence) and between the electrocoagulation combined with allopurinol or dimethyl sulphoxide groups versus the control group (RR 1.00, 95% CI 0.09 to 10.86; 231 participants; very low-certainty evidence). The trial authors did not report data on number of participants with other adverse events and complications, recurrence of liver metastases, time to progression of liver metastases, tumour response measures, and health-related quality of life. Data on failure to clear liver metastases were not provided for the control group. There was no information on funding or conflict of interest. We identified no ongoing trials.
AUTHORS' CONCLUSIONS
The evidence on the beneficial and harmful effects of electrocoagulation alone or in combination with allopurinol or dimethyl sulphoxide in people with liver metastases is insufficient, as it is based on one randomised clinical trial at low to very low certainty. It is very uncertain if there is a difference in all-cause mortality and post-operative mortality between electrocoagulation alone versus control. It is also uncertain if electrocoagulation in combination with allopurinol or dimethyl sulphoxide may result in a slight reduction of all-cause mortality in comparison with a vehicle solution of allopurinol (control). It is very uncertain if there is a difference in post-operative mortality between the electrocoagulation combined with allopurinol or dimethyl sulphoxide group versus control. Data on other adverse events and complications, failure to clear liver metastases or recurrence of liver metastases, time to progression of liver metastases, tumour response measures, and health-related quality of life were most lacking or insufficiently reported for analysis. Electrocoagulation by diathermy is no longer used in the described way, and this may explain the lack of further trials.

Meta-Analysis
Wire-guided localization (WGL) is the most frequently used localization technique in non-palpable breast cancer (BC). However, low negative margin rates, patient discomfort, and the possibility of wire dislocation have been discussed as potential disadvantages, and re-operation due to positive margins may increase relapse risk. Intraoperative ultrasound (IOUS)-guided excision allows direct visualization of the lesion and the resection volume and reduces positive margins in palpable and non-palpable tumors. We performed a systematic review on IOUS in breast cancer and 2 meta-analyses of randomized clinical trials (RCTs). In non-palpable BC, 3 RCTs have shown higher negative margin rates in the IOUS arm compared to WGL. Meta-analysis confirmed a significant difference between IOUS and WGL in terms of positive margins favoring IOUS (risk ratio 4.34, p < 0.0001, I2 = 0%). 41 cohort studies including 3291 patients were identified, of which most reported higher negative margin and lower re-operation rates if IOUS was used. In palpable BC, IOUS was compared to palpation-guided excision in 3 RCTs. Meta-analysis showed significantly higher rates of positive margins in the palpation arm (risk ratio 2.84, p = 0.0047, I2 = 0%). In 13 cohort studies including 942 patients with palpable BC, negative margin rates were higher if IOUS was used, and tissue volumes were higher in palpation-guided cohorts in most studies. IOUS is a safe noninvasive technique for the localization of sonographically visible tumors that significantly improves margin rates in palpable and non-palpable BC. Surgeons should be encouraged to acquire ultrasound skills and participate in breast ultrasound training.

Review
BACKGROUND
Traditional open orchiopexy is still a standard of treatment for palpable undescended testicles. Recently several authors reported successful results using a laparoscopic approach in the treatment of palpable cryptorchidism. The present systematic review and meta-analysis investigated the utility of laparoscopic orchiopexy for palpable cryptorchidism.
METHODS
Scientific databases (PubMed, Scopus, Web of Science, and EMBASE) were systematically searched for relevant articles using the following terms: (palpable cryptorchidism or palpable undescended testes) AND (laparoscopic orchiopexy or laparoscopic orchiopexy). The inclusion criteria were all children with unilateral or bilateral palpable undescended testes who underwent laparoscopic orchiopexy (LO) compared to children who underwent conventional open orchiopexy (CO). The main outcomes were the proportion of children requiring redo-orchiopexy and the incidence of postoperative complications. Secondary outcomes were duration and the cost of surgery.
RESULTS
The final meta-analysis included five studies involving 705 children; LO, = 369 (52.3%) and CO, = 336 (47.7%). The majority of the included patients had unilateral palpable cryptorchidism. No significant differences were found in regard to average age at the time of surgery and follow-up periods between the investigated groups. No statistically significant differences were found in regard to redo-orchiopexy rates (RR = 0.22, 95% CI 0.03-1.88, = 0.17), early complications (RR = 0.66, 95% CI 0.21-2.08, = 0.48) and incidence of testicular atrophy (RR = 0.36, 95% CI 0.03-3.88, = 0.40). No significant differences in the operative duration were observed among the groups. Laparoscopy was associated with higher costs in most of the studies.
CONCLUSION
LO is safe and effective in children with palpable cryptorchidism. The rates of redo-orchiopexy as well as an incidence of early complications and testicular atrophy rates are comparable to CO.
