Endoscopic ultrasound-rendezvous versus percutaneous-endoscopic rendezvous endoscopic retrograde cholangiopancreatography for bile duct access: Systematic review and meta-analysis.
OBJECTIVES
Endoscopic ultrasound (EUS) or percutaneous-assisted antegrade guidewire insertion can be used to achieve biliary access when standard endoscopic retrograde cholangiopancreatography (ERCP) fails. We conducted a systematic review and meta-analysis to evaluate and compare the effectiveness and safety of EUS-assisted rendezvous (EUS-RV) and percutaneous rendezvous (PERC-RV) ERCP.
METHODS
We searched multiple databases from inception to September 2022 to identify studies reporting on EUS-RV and PERC-RV in failed ERCP. A random-effects model was used to summarize the pooled rates of technical success and adverse events with 95% confidence interval (CI).
RESULTS
In total, 524 patients (19 studies) and 591 patients (12 studies) were managed by EUS-RV and PERC-RV, respectively. The pooled technical successes were 88.7% (95% CI 84.6-92.8%, I = 70.5%) for EUS-RV and 94.1% (95% CI 91.1-97.1%, I = 59.2%) for PERC-RV (P = 0.088). The technical success rates of EUS-RV and PERC-RV were comparable in subgroups of benign diseases (89.2% vs. 95.8%, P = 0.068), malignant diseases (90.3% vs. 95.5%, P = 0.193), and normal anatomy (90.7% vs. 95.9%, P = 0.240). However, patients with surgically altered anatomy had poorer technical success after EUS-RV than after PERC-RV (58.7% vs. 93.1%, P = 0.036). The pooled rates of overall adverse events were 9.8% for EUS-RV and 13.4% for PERC-RV (P = 0.686).
CONCLUSIONS
Both EUS-RV and PERC-RV have exhibited high technical success rates. When standard ERCP fails, EUS-RV and PERC-RV are comparably effective rescue techniques if adequate expertise and facilities are feasible. However, in patients with surgically altered anatomy, PERC-RV might be the preferred choice over EUS-RV because of its higher technical success rate.

Thyroglossal duct (TGD) remnants in the form of cysts or fistulas usually present as midline neck masses and they are removed along with the central body of the hyoid bone (Sistrunk's procedure). For other pathologies associated with the TGD tract, the latter operation might be not necessary. In the present report, a case of a TGD lipoma is presented and a systematic review of the pertinent literature was performed. We present the case of a 57-year-old woman with a pathologically confirmed TGD lipoma who underwent transcervical excision without resecting the hyoid bone. Recurrence was not observed after six months of follow-up. The literature search revealed only one other case of TGD lipoma and controversies are addressed. TGD lipoma is an exceedingly rare entity whose management might avoid hyoid bone excision.

Review
Most surgeons have traditionally been reluctant toward minimally-invasive surgery for bile duct tumors. This study aimed to perform a systematic literature review on perioperative and oncologic results of pure laparoscopic and robotic curative-intent surgery for hilar cholangiocarcinoma. According to the PRISMA statement, a systematic review was conducted into Pubmed, EMBASE and Cochrane. A critical appraisal of study was performed according to the Joanna Briggs Institute tools. Nineteen studies (12 on pure laparoscopy and 7 on robotics) were included: 7 case reports, 9 case series, 3 case-control (193 patients). The pooled conversion, morbidity, biliary leak and mortality rates were 5.5%, 43%, 16.4% and 4%. The weighted mean of operative time, blood loss and postoperative stay were 388 min, 446 mL and 14 days. For pure laparoscopy, the pooled R0 rate was 86%; overall survival and disease-free survival rates ranged from 85 to 100% and from 80 to 100% (median observation time 6-18 months). For robotic surgeries, the pooled R0 rate was 69% and overall survival rates ranged from 90 to 100% (median observation time 5-15 months). Case reports were overall of high quality, case series of moderate / high-quality, case-control studies ranged from low to high quality. In selected patients, minimally-invasive surgery for Klatskin tumors appears feasible, safe, satisfactory for perioperative outcomes and adequate for oncologic results. However, the results are based on few studies, limited in patient numbers and with allocation criteria more restrictive than open, reporting short follow-up and mainly with non-comparative design: evidence of higher quality is recommended.

Meta-Analysis Review
OBJECTIVE
Sphincter of Oddi dysfunction (SOD) has been used to describe patients with RUQ abdominal pain without an etiology. We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of ES (endoscopic sphincterotomy) for SOD.
METHODS
The study methodology follows the PRISMA guidelines. A comprehensive search was conducted using MEDLINE and EMBASE databases for RCTs with ES in patients with SOD. The primary outcome assessed was the improvement of abdominal pain after ES/sham. A random effects model was used to calculate pooled estimates for each outcome of interest.
RESULTS
Of the initial 55 studies, 23 were screened and thoroughly reviewed. The final analysis included 3 studies. 340 patients (89.7% women) with SOD were included. All patients had a cholecystectomy. Most included patients had SOD type II and III. The pooled rate of technical success of ERCP was 100%. The average clinical success rate was 50%. The pooled cumulative rate of overall AEs related to all ERCP procedures was 14.6%. In the sensitivity analysis, only one study significantly affected the outcome or the heterogeneity.
CONCLUSION
ES appears no better than placebo in patients with SOD type III. Sphincterotomy could be considered in patients with SOD type II and elevated SO basal pressure.

Review
OBJECTIVES
To assess through literature case analysis how advances in lymphatic imaging, interventional radiology, and lymphatic vascular microsurgery illuminate and improve the lymphatic-flow status in select patients with Noonan syndrome (NS) who have undergone surgical intervention as a part of their comprehensive and individualized treatment plan. Also, we sought to illustrate the spectrum of lymphatic complications that can occur in this patient population when lymphatic flow through abnormal vasculature is surgically disrupted.
METHODS
A literature review was performed by searching "Noonan AND Lymphatic AND Imaging" in the PubMed database. Inclusion criteria for this study were (1) diagnosis and clinical description of at least one original patient with NS, (2) imaging figures depicting lymphatic structure and function or a description of lymphatic imaging findings when a figure is not present, and (3) documentation of either lymphatic surgical intervention or lymphatic complications resulting from other procedures. Patient cases were first grouped by documented surgical intervention type, then clinical outcomes and lymphatic imaging results were compared.
RESULTS
A total of 18 patient cases from 10 eligible publications were included in our review. Lymphatic imaging findings across all patients included lymphatic vessel dysplasia along with flow disruption (n = 16), thoracic duct malformations (n = 12), dermal lymphatic reflux (n = 7), and dilated lymphatic vessels (n = 4). Lymphovenous anastomosis (n = 4) resulted in rapid improvement of patient symptoms and signs. New-onset lymphatic manifestations noted over 10 to 20 years for two of these patients were chylothorax (n = 1), erysipelas (n = 1), and gradual-onset nonchylous scrotal lymphorrhea (n = 1). Targeted endovascular lymphatic disruption via sclerosis, embolization, or ablation (n = 8) results were mixed depending on the degree of central lymphatic involvement and included resolution of symptoms (n = 1), postoperative abdominal hemorrhage (n = 1), stable condition or minor improvement (n = 5), and death (n = 2). Large lymphatic vessel ligation or accidental incision (n = 6) occurred during thoracotomy (n = 4), scrotoplasty (n = 1), or inguinal lymph node biopsy (n = 1). These resulted in postoperative onset of new-onset regional lymphatic reflux (n = 5), chylothorax (n = 4), death (n = 3), or persistent or unchanged symptoms (n = 1).
CONCLUSIONS
Imaging of the central lymphatics enabled characterization of lymphatic developmental features and guided operative management of lymphatic vascular defects in patients with NS. This review of the literature suggests that the surgical preservation or enhancement of central lymphatic return in patients with NS may improve interventional outcomes, whereas the disruption of central lymph flow has significant potential to cause severe postoperative complications and worsening of the patient's clinical condition.

Meta-Analysis Review
BACKGROUND
Pancreatic duct occlusion (PDO) without anastomosis is a technique proposed to mitigate the clinical consequences of postoperative pancreatic fistulas (POPF) after pancreaticoduodenectomy. The aim of this study was to appraise the morbidity following PDO through a systematic review and meta-analysis.
METHODS
A systematic search of MEDLINE, Embase, and Web Of Science identified studies reporting outcomes of PDO following pancreaticoduodenectomy. Pooled prevalence rates of postoperative complications and mortality were computed using random-effect modeling. Meta-regression analyses were performed to examine the impact of moderators on the overall estimates.
RESULTS
Sixteen studies involving 1000 patients were included. Pooled postoperative mortality was 2.7%. A POPF was reported in 29.7% of the patients. Clinically relevant POPFs occurred in 13.5% of the patients, while intra-abdominal abscess and haemorrhages occurred in 6.7% and 5.5% of the patients, respectively. Re-operation was necessary in 7.6% of the patients. Postoperatively new onset diabetes occurred in 15.8% of patients, more frequently after the use of chemical substances for PDO (p = 0.003).
CONCLUSIONS
PDO is associated with significant morbidity including new onset of post-operative diabetes. The risk of new onset post-operative diabetes is associated with the use of chemical substance for PDO. Further evidence is needed to evaluate the potential benefits of PDO in patients at high risk of POPF.

BACKGROUND
The occurrence of a cluster of occupational cholangiocarcinoma(CCA) cases among Japanese workers at a small offset printing plant led to the hypotheses that occupational exposure was the root cause of this cancer. Numerous workplace carcinogens can be found at various jobs sites and are integral to various industrial processes. Therefore, a systematic evaluation of potential occupationally-related CCA and likely exposure types is needed.
OBJECTIVE
To conduct a systematic review on the cause of CCA in relation to occupation.
METHODS
The systematic review included papers published between 1980 and 2020. Databases included PubMed, Science Direct, CINAHL, ProQuest Medical Library, Springer, Wiley online library, and the Cochrane library. The review focused on CCA, intrahepatic CCA(as distinct from other types of liver cancer), and extrahepatic CCA(not including the gallbladder). While some occupations involve an expected risk of exposure to carcinogens, this study sought both primary reports on specific carcinogens or surrogates by occupation or industry title. Of the 65 English version abstracts, 18 studies were selected for in-depth review according to the eligibility criteria. Two occupational physicians independently assessed the relevance to the study objectives, data extractability, and data quality as per the Newcastle-Ottawa Scale.
RESULTS
The review revealed that ten observational studies met the eligibility criteria. There was heterogeneity of occupational exposure assessment and the reported results. The possible carcinogens statistical significantly related to the incidence or mortality of CCA risk included 1,2-dichloropropane (the highest RR = 32.40, 95%CI=6.40-163.90), asbestos (the highest OR=4.81, 95 % CI =1.73-13.33), endocrine-disrupting compounds (the highest OR =2.00, 95% CI=1.10-3.70), and rotating shift work (the highest HR =1.97, 95%CI=1.02-3.79). These carcinogens are classified as IARC class 1 and 2A.
CONCLUSIONS
Despite the limited number of studies reviewed, the hypothesis of occupational risk for CCA was supported. Occupational health and safety measures may decrease exposure to these carcinogens, and surveillance in high-risk occupations or industries is urgently needed to prevent and control CCA.

Meta-Analysis Review
Postoperative morbidity and mortality after pancreatoduodenectomy with pancreatic duct occlusion compared to pancreatic anastomosis: a systematic review and meta-analysis.
BACKGROUND
Pancreatoduodenectomy is burdened by elevated postoperative morbidity. Pancreatic duct ligation or occlusion have been experimented as an alternative to reduce the insurgence of postoperative pancreatic fistula. The aim of this systematic review and meta-analysis was to compare postoperative mortality and morbidity (pancreatic fistula, postoperative hemorrhage, delayed gastric emptying, pancreatic exocrine insufficiency and diabetes mellitus) between patients undergoing pancreatic anastomosis or pancreatic duct ligation/occlusion after pancreatoduodenectomy.
METHODS
A systematic review and meta-analysis of 13 studies was conducted following the PRISMA guidelines and the Cochrane protocol (PROSPERO ID: CRD42021249232).
RESULTS
No difference in postoperative mortality was highlighted. Pancreatic anastomosis was found to be protective considering all-grades pancreatic fistula (RR: 2.38, p = 0.0005), but pancreatic duct occlusion presented a 3-folded reduced risk to develop "grade C" pancreatic fistula (RR: 0.36, p = 0.1186), although not significant. Diabetes mellitus was more often diagnosed after duct occlusion (RR: 1.61, p < 0.0001); no difference was found in terms of pancreatic exocrine insufficiency (RR: 1.19, p = 0.151).
CONCLUSION
Postoperative mortality is not influenced by the pancreatic reconstruction technique. Pancreatic anastomosis is associated with a reduction in all-grades pancreatic fistula. More high-quality studies are needed to clarify if duct sealing could reduce the prevalence of "grade C" fistula.

INTRODUCTION
Sialorrhea or drooling can result in physical and psychosocial complications, such as aspiration and social isolation. Treatment options include botulinum toxin into the salivary glands and 4-duct ligation (i.e., simultaneous ligation of the bilateral parotid and submandibular ducts). This systematic review aimed to compare the efficacy and complication rates of botulinum toxin and 4-duct ligation for the treatment of drooling in children.
METHODS
Following PRISMA guidelines, PubMed, Embase, Web of Science, and Cochrane Library were searched from inception through June 17, 2021 for studies examining the efficacy of botulinum toxin or 4-duct ligation for drooling in children. Data were summarized by pooled counts, percentages, and means. Complication rates were compared by a chi-squared test.
RESULTS
A total of 22 studies (n = 606) examining botulinum toxin and 5 studies (n = 124) examining 4-duct ligation were included. From 12 botulinum toxin studies (n = 211), mean drooling frequency and severity scores was 7.5 at baseline. Mean difference from baseline was -2.6 (n = 92) at 4 weeks follow-up, -2.1 at 8 weeks (n = 41), -2.1 at 12 weeks (n = 56), and - 2.1 at 16 weeks (n = 58). From 4 4-duct ligation studies (n = 103), mean baseline drooling frequency and severity score was 8.4. Mean difference was -3.7 at mean follow-up of 35.6 months (n = 103). Eighteen botulinum studies (n = 343) recorded 53 (15.5 %) complications, including thickened saliva (n = 9), dysphagia (n = 4), and cheek abscesses (n = 4). Four 4-duct ligation studies (n = 108) recorded 25 (23.1 %) complications, including parotid gland swelling (n = 4), aspiration pneumonia (n = 3), and oxygen desaturation (n = 3). There was no statistically significant difference in complication rates between botulinum toxin and four-duct ligation (p = 0.065).
CONCLUSION
Botulinum toxin injection and 4-duct ligation are both effective in improving sialorrhea in children and have comparable complication rates.

Meta-Analysis Review
OBJECTIVES
Salivary duct carcinoma (SDC) is a rare, aggressive malignancy with a poor prognosis. These tumors frequently stain positive for HER2/ErbB2, but data on the prognostic significance of HER2 status in SDC are mixed. We sought to determine whether HER2 status affects survival outcomes in SDC.
METHODS
PubMed, Embase, and Web of Science databases were searched from inception to October 2020. Eligibility was restricted to studies reporting HER2/ErbB2 overexpression in histologically confirmed de novo SDC or SDC ex pleomorphic adenoma, with corresponding overall (OS) and disease-free (DFS) survival measures. Separate multivariable and univariable meta-analyses were performed using random-effects models. Statistical heterogeneity was estimated by Cochran's Q and I tests. Funnel plots were generated and Egger's test was used to assess for publication bias. The risk of bias was assessed with the Newcastle-Ottawa Scale.
RESULTS
Of 183 unique citations, 14 studies of 663 patients were included. Most included studies determined HER2 status according to ASCO/CAP guidelines. The univariable meta-analysis did not reveal an effect between HER2 status and OS (HR 1.09, 95% CI 0.84-1.42). In the multivariable analysis, HER2 positivity was associated with a HR of 1.49 for OS (95% CI 0.96-2.30). Fewer studies reported data for DFS than OS, with no relationship between HER2 status and DFS found on multivariable or univariable meta-analyses.
CONCLUSION
In patients with salivary duct carcinoma, HER2 positivity was not found to be associated with worse overall survival. This information may be useful when counseling patients and considering treatment options. Laryngoscope, 133:476-484, 2023.
