Abstract
BACKGROUND Minimally invasive surgery for intrahepatic cholangiocarcinoma (ICC) remains challenging, especially in advanced patients. PATIENT AND METHOD A 66-year-old male was diagnosed with stage II ICC after a comprehensive evaluation and was scheduled for laparoscopic exploration and left hepatectomy. RESULTS The pure laparoscopic left hepatectomy was completed in 240 min, employing a no-touch en bloc technique and lymphadenectomy skeletonization. The patient was discharged 6 days after the operation without any complications and received gemcitabine and cisplatin treatment postoperatively. There was no recurrence during 14 months of follow-up. CONCLUSIONS Our experience demonstrates that when utilizing the no-touch en bloc technique, standardized lymphadenectomy through skeletonization, and effective control of bleeding, surgeons with extensive expertise in laparoscopic hepatectomy can achieve results comparable to open surgery.

Abstract
PURPOSES Closure of the appendix stump is necessary for laparoscopic appendectomy. Problems that occur during the appendix stump closure can cause severe morbidity. Several methods of stump closure have been described. This study aimed to investigate the adequacy of LigaSure alone in closing the appendix stump. METHODS Patients who were operated on with the diagnosis of acute appendicitis between October 2021 and January 2022 were evaluated retrospectively. The patients were divided into two groups according to the closure technique of the appendix stump hemoclip(group I) and LigaSure only(group II). In addition, demographic data (age, gender), body mass index (BMI), presence of comorbid disease, perioperative appendicitis classification, operation time, postoperative hospital stay, radiological and pathological appendix size of the patients included in the study were recorded. Clavien Dindo was used for postoperative complication assessment. RESULT The study included 77 patients. 48(62.3%) of the patients were in group I, and 29(37.7%) were in group II. There was no statistical difference between the groups regarding age, gender distribution, BMI, presence of comorbid disease (P > .05). The operation time of group I was longer than group II (P < .001). There was no difference between the groups in terms of both radiological and pathological appendix size. There was no statistical difference between the groups regarding postoperative complications and severity of complications (P = .76, P = .99, respectively). CONCLUSION Appendiceal stump closure can be performed with Ligasure, but it should be noted that this procedure can be performed on selected patients, as in the study group, not on all patients.

An umbrella review of the surgical performance of Harmonic ultrasonic devices and impact on patient outcomes. BMC Surg 2023; 23:180. [PMID: 37386399 PMCID: PMC10308659 DOI: 10.1186/s12893-023-02057-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 05/25/2023] [Indexed: 07/01/2023] Open
Abstract
BACKGROUND For thirty years, the Harmonic scalpel has been used for precise dissection, sealing and transection. There are numerous meta-analyses on individual surgical procedures with Harmonic, but no overarching review covering all the areas. This umbrella review seeks to summarize the clinical results from the use of Harmonic across surgical fields and broadly quantify its effects on patient outcomes. METHODS MEDLINE, EMBASE, and Cochrane Databases were searched for meta-analyses (MAs) of randomized controlled trials (RCTs) comparing Harmonic devices to conventional techniques or advanced bipolar (ABP) devices. For each procedure type, the most comprehensive MAs were evaluated. RCTs not already analysed in a MA were also included. Operating time, length of stay, intraoperative blood loss, drainage volume, pain, and overall complications were evaluated, and the methodological quality and certainty of evidence were assessed. RESULTS Twenty-four systematic literature reviews were identified on colectomy, hemorrhoidectomy, gastrectomy, mastectomy, flap harvesting, cholecystectomy, thyroidectomy, tonsillectomy, and neck dissection. There were also 83 RCTs included. In every MA evaluated, Harmonic devices were associated with either statistically significant or numerical improvements in every outcome compared with conventional techniques; most MAs reported a reduction in operating time of ≥ 25 min. Harmonic versus ABP device MAs in colectomy and thyroidectomy showed no significant differences in outcomes. CONCLUSION Across surgical procedures, Harmonic devices demonstrated improved patient outcomes for operating time, length of stay, intraoperative bleeding, drainage volume, pain, and overall complications compared to conventional techniques. Additional studies are required to assess differences between Harmonic and ABP devices.

Abstract
Background: Laparoscopic appendectomy has long been in the process of replacing open appendectomy owing to a better wound healing, better cosmetic appearance, less pain, and less postoperative adhesion. Although there are many methods for ligating the appendix stump, studies on energy-based coagulation methods have attracted great interest in recent years. In our study, we aimed to compare the use of LigaSure™ appendiceal sealing and ligation of appendiceal stump by endoloop with regard to duration of surgery, length of hospital stay, and complications in laparoscopic appendectomies. Materials and Methods: A total of 174 consecutive patients under the age of 18 who underwent laparoscopic appendectomy in our clinic between September 2016 and February 2021 were retrospectively analyzed. Patients with perforated appendicitis were excluded from the study. The patients were divided into two groups as the appendix stump was ligated with endoloop (Group 1) and sealed with LigaSure (Group 2). Demographic characteristics of the patients, duration of surgery, length of hospital stay, and complications were recorded. Results: Of the 132 patients who were included in the study, Group 1 consisted of patients using endoloop (n = 39) and Group 2 comprised patients that LigaSure was employed (n = 93). There was no significant difference between Groups 1 and 2 in terms of age and length of hospital stay (P = .126 and P = .784, respectively); however, the operation time was found to be significantly shorter in Group 2 (P < .001). Conclusion: The use of LigaSure is a safe and fast method to seal the mesoappendix and appendix stump in pediatric laparoscopic appendectomy. We think that infection complications due to stump leakage and intra-abdominal spillage will less be encountered.

Abstract
Intestinal aganglionosis in children is a common cause of neonatal and infantile obstruction or ileus. Diagnosis is based on a histologically proven absence of enteric ganglion cells in deep biopsies of the gut wall. Therapeutic goal is a one-stage repair with a resection of the affected segment. The endorectal pull-through (ERP) can be performed entirely transanally in a lot of the cases. In patients with difficult preparation or a high aganglionosis ERP often needs to be assisted by laparoscopy or laparotomy. We present two cases with a technical modification performing a totally transanal pull-through colectomy without any trocars other than an umbilical camera trocar. The procedure starts with a classical endorectal technique. Usually, the transanal preparation is limited by reaching the colon descendens. A camera trocar is inserted and under laparoscopic vision the preparation is completed placing the instruments directly via the opened anus. After reaching the healthy colon segment, the pull-through is completed transanally. One of the main advantages of ERP is the sparing dissection. Our modification combines advantages of laparoscopy and ERP. The umbilical camera allows an excellent view while the instruments for dissection are used like with ERP without any further trocar or traction of the anal sphincter. The dispensation of any transanal trocar allows a higher grade of freedom in preparation and possibly a smaller trauma on the distal anal channel.

Abstract
In recent decades, the use of energy-based devices has substantially increased the incidence of iatrogenic thermal injury to nerves (cauterization, etc.). While recovery of the nerve after thermal injury is important, the changes in neural structure, function, and peripheral inflammatory reactions postinjury remain unclear. This study is aimed at demonstrating the changes mentioned above during the acute, subacute, and chronic stages of nerve reinnervation after thermal injury. Spontaneous reinnervation was evaluated, including the neural structures, nerve conduction abilities, and muscle regeneration. These effects vary depending on the severity of thermal injury (slight, moderate, and severe). Peripheral inflammatory reactions, as impediments to reinnervation, were found in significant numbers 3 days after thermal injury, exhibiting high expression of IL-1β and TNF-α, but low expression of IL-10. Our findings reveal the pathogenesis of peripheral nerve reinnervation after thermal injury, which will assist in selecting appropriate treatments in further research.

[PMID: 36105859 PMCID: PMC9464866 DOI: 10.3389/fped.2022.998106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Accepted: 08/05/2022] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND AND OBJECTIVE In spite of being one of the most common surgical procedures performed in adults, laparoscopic cholecystectomy (LC) is relatively uncommon in the pediatric age group. Most surgeons prefer to dissect the cystic duct using a monopolar electrosurgical hook and occlude it with simple metal clips. Although the safety of using the ultrasonically-activated shears, e.g., harmonic scalpel for dissection of the gallbladder is confirmed in many studies, its efficacy in the closure of the cystic artery and duct in adults is still debatable. Furthermore, very few reports studied its safety in children during LC. The aim of our work is to study the safety and efficacy of ultrasonic shears in controlling the cystic duct and artery during LC in children. MATERIALS AND METHODS A prospective study was conducted from May 2017 to April 2020, where all children having symptomatic gallbladder stone disease were included in the study. HS was used as a sole instrument in gallbladder dissection as well as in controlling cystic duct and artery. No metal clips or sutures were used throughout the procedure. RESULTS A total of forty-two children having symptomatic gallstone disease were included in the study. The main indication for LC was hemolytic anemia. Their age ranged from 3 to 13 years with a mean of 8.4 ± 3.25 years. All operations were completed laparoscopically, i.e., no conversion to open surgery was needed. The mean operative time was 40 ± 10.42 min. There were no intraoperative complications apart from gall bladder perforation in two cases during dissection from the liver bed while the postoperative recovery was smooth in all patients. Patients started oral feeding after 11.30 ± 3.01 h. The mean time for discharge was 25.47 ± 7.49 h, ranging from 14 to 48 h. Postoperative ultrasound for all cases showed no evidence of minor or major bile leaks or CBD injuries. CONCLUSION This is the first report to evaluate the use of HS as a sole instrument during LC in the pediatric age group. HS is a safe and efficient instrument that can be used alone in gallbladder dissection as well as in controlling cystic duct and artery during LC in children.

A new approach to laparoscopic appendectomy in children-clipless/sutureless Harmonic scalpel laparoscopic appendectomy. Langenbecks Arch Surg 2021; 407:779-787. [PMID: 34841456 DOI: 10.1007/s00423-021-02389-1] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Accepted: 11/25/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND The aim of this study was to investigate Harmonic scalpel performance in laparoscopic appendectomy for sealing the base of the appendix in children. METHODS During the study period, a total of 312 patients who underwent laparoscopic appendectomy were included in prospective bicenter clinical trial. The patients were divided in two study groups in regard to technique used for appendiceal base closure. In the first group (n = 197) the appendiceal base was secured using a polymeric clip while in the second group (n = 115) the Harmonic scalpel was used for sealing the base in a stepwise manner, without placing any clip or suture. Outcomes of treatment, including complication rates, duration of surgery and length of hospital stay were compared between the groups. RESULTS A total of 312 patients with a median age of 11 years (IQR 8, 15) were included in study. Of these, 191 were males (61.2%). Both groups were symmetric in regard to baseline characteristics of the patients. A total of 10 (5.1%) postoperative complications (postoperative abscess n = 7 and ileus n = 3) were recorded in the polymeric clip group while none of the patients from the clipless group had postoperative complications (P = 0.015). In the group who received a polymeric clip appendectomy, fever lasting 0-72 h and > 72 h was recorded in 16 (8.1%) and 12 (6.1%) children, respectively, while in the clipless group, it was observed in 2 (1.7%) and 5 (4.3%) children, respectively (P = 0.048). Significantly shorter surgical times were found in the clipless group compared to the polymeric clip group (21 min (IQR 18, 25) vs. 30 min (IQR 22, 40), P < 0.0001). Also, length of hospital stay was significantly shorter in the clipless group of the patients (2 days (IQR 2, 3) vs. 3 days (IQR 2, 4), P < 0.0001). CONCLUSION Clipless harmonic scalpel laparoscopic appendectomy is a safe and effective method in children for treatment of acute appendicitis with lesser number of complications and shorter duration of surgery compared to laparoscopic appendectomy in which the appendiceal base is secured with clip.

Abstract
BACKGROUND The aim of this study was to investigate hyponatremia as a new biochemical marker associated with complicated appendicitis in the pediatric population. METHODS Pediatric patients (n = 184) with acute appendicitis confirmed by histopathology were enrolled in a prospective cohort study from January 2019 to May 2020. Medical history, demographic and clinical data were recorded in the study protocol. Blood samples for biochemical analysis, electrolytes and acute inflammatory markers were taken before surgery. Patients were further divided in two groups, those with non-perforated (n = 148; 79%) and perforated appendicitis (n = 38; 21%). RESULTS The mean serum sodium level in patients with complicated appendicitis was significantly lower compared to patients with non-complicated appendicitis (132.2 mmol/L vs. 139.2 mmol/L, p < 0.001). The receiver operating characteristic curve of plasma sodium concentration in patients who were diagnosed with perforated acute appendicitis showed an area under the curve of 0.983 (95% CI, 0.963-1.00). A cut-off-value of plasma sodium concentration of ≤135 mmol/L was shown to give the best possible sensitivity and specificity, 94.7% (95% CI: 82.2-99.3) and 88.5% (95% CI: 88.2-93.2) respectively (p < 0.001). Patients with complicated appendicitis were more likely to be younger than five years of age (10.5% vs. 1.4%, p = 0.005), have a duration of symptoms for >24 h (97.4% vs. 59.6%, p < 0.001), sodium serum concentration ≤135 mmol/L (89.5% vs. 5.5%, p < 0.001), body temperature >38.5 °C (47.4% vs. 11.0%, p < 0.001) and CRP serum concentration >62 mg/L (26% vs. 2%, p < 0.001). CONCLUSION Hyponatremia is a novel and very discriminative marker of complicated appendicitis in the pediatric population, and is therefore recommended in appendicitis diagnostic and treatment planning. TYPE OF STUDY Prospective comparative study LEVEL OF EVIDENCE: II.

The Safety and Effectiveness of Laparoscopic Pyloromyotomy Using 3-mm Electrocautery Hook versus Open Surgery for Treatment of Hypertrophic Pyloric Stenosis in Infants. CHILDREN-BASEL 2021; 8:children8080701. [PMID: 34438592 PMCID: PMC8392573 DOI: 10.3390/children8080701] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 08/12/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND The standard of treatment for infants with hypertrophic pyloric stenosis is still pyloromyotomy. Recently, in most of the pediatric surgery centers laparoscopic pyloromyotomy has become popular. The aim of the present study is to compare the outcomes of treatment in infants with hypertrophic pyloric stenosis between traditional open approach and laparoscopic pyloromyotomy using 3-mm electrocautery hook. METHODS A total of 125 infants, 104 (83.2%) males, with median age 33 (interquartile range, IQR 24, 40) days, who underwent pyloromyotomy because of hypertrophic pyloric stenosis, between 2005 and 2021, were included in the retrospective study. Of that number 61 (48.8%) infants were allocated to the open group and 64 (51.2%) to the laparoscopic group. The groups were compared in regards to time to oral intake, duration of surgery, the type and rate of complications, rate of reoperations, frequency of vomiting after surgery, and the length of hospital stay. RESULTS No differences were found with regards to baseline characteristics between two investigated groups. Laparoscopic approach was associated with significantly better outcomes compared to open approach: shorter duration of surgery (35 min (IQR 30, 45) vs. 45 min (40, 57.5); p = 0.00008), shorter time to oral intake (6 h (IQR 4, 8) vs. 22 h (13.5, 24); p < 0.00001), lower frequency of postoperative vomiting (n = 10 (15.6%) vs. n = 19 (31.1%)), and shorter length of postoperative hospital stay (3 days (IQR 2, 3) vs. 6 days (4.5, 8); p < 0.00001). In regards to complications and reoperation rates, both were lower in the laparoscopic pyloromyotomy group but the differences were not statistically significant (p = 0.157 and p = 0.113, respectively). The most common complication in both groups was mucosal perforation (open group, n = 3 (4.9%); laparoscopic group, n = 2 (3.1%)) followed by wound infection in open group, n = 3 (4.9%). No cases of wound infection were recorded in the laparoscopic group. CONCLUSION Open and laparoscopic pyloromyotomy are equally safe and effective in treatment of hypertrophic pyloric stenosis. Laparoscopic technique is associated with faster recovery, shorter duration of surgery and shorter duration of hospital stay.

Abstract
Background: This prospective cohort study aimed to investigate the association of hyperbilirubinemia with perforated appendicitis in the pediatric population. Patients and Methods: A total of 284 children in whom the diagnosis of acute appendicitis was established were included in this study. The patients were allocated in study groups in regard to operative findings. The first study group included patients who had perforated appendicitis (n = 64; 22.5%) whereas the patients in the second group had simple appendicitis (n = 220; 77.5%). Blood samples for serum bilirubin levels and acute inflammatory markers were taken before the patients underwent surgery. The primary outcome of the study was to investigate whether the level of serum bilirubin should be used to distinguish between simple and perforated appendicitis. Results: The median level of serum bilirubin in children with perforated appendicitis was 27 mcmol/L whereas the patients with simple appendicitis had lower median levels of serum bilirubin (10 μmol/L; p < 0.001). An area under the receiver operating characteristic (ROC) curve for total serum bilirubin was 0.876 (95% confidence interval [CI], 0.820-0.929) in the patients who had a perforated appendicitis. An ROC analysis showed the best sensitivity (92%) and specificity (77.3%) for a cutoff value of 15.5 mcmol/L for total serum bilirubin (p < 0.001). Hyperbilirubinemia at admission was found in 35 patients (54.7%) with complicated appendicitis and in 14 patients (6.4%) with non-perforated appendicitis (p < 0.001). The modeling of collected data by multivariable logistic regression identified serum bilirubin concentration (odss ratio [OR] = 1.12; 95% CI, 1.07-1.18; p < 0.001), serum sodium concentration (OR = 0.64; 95% CI, 0.51-0.81; p < 0.001), body temperature (OR = 2.48; 95% CI, 1.05-0.84; p < 0.001), and duration of symptoms (OR = 1.06; 95% CI, 1.02-1.09; p < 0.001) as risk factors for perforated appendicitis. Conclusion: Elevateds level of total serum bilirubin may be useful as an indicator of perforated appendicitis in children. Levels of bilirubin in serum is an inexpensive, simple, and available laboratory marker and should therefore be recommended in the initial evaluation for acute appendicitis in pediatric patients.

Abstract
Introducción. La apendicectomía por laparoscopia se considera el patrón de oro en el tratamiento de la apendicitis aguda. Sin embargo, su disponibilidad es limitada en nuestro sistema de salud, principalmente por los costos asociados. El objetivo de este estudio fue evaluar la relación entre el uso de los diferentes tipos de energía y los métodos de ligadura de la base apendicular, con las complicaciones postoperatorias, al igual que describir los costos asociados.
Métodos. Estudio observacional analítico de una cohorte retrospectiva de pacientes mayores de 15 años a quienes se les realizó apendicectomía por laparoscopia, en un hospital universitario entre los años 2014 y 2018. Se utilizaron modelos de regresión logística y lineal para evaluar la relación entre métodos de ligadura del meso y base apendicular, desenlaces operatorios y costos.
Resultados. Se realizaron 2074 apendicectomías por laparoscopia, 58,2 % (n=1207) en mujeres, la edad mediana fue de 32 años. En el 71,5 % (n=1483) la apendicitis aguda no fue complicada. La energía monopolar para la ligadura del meso apendicular fue la utilizada más frecuentemente en 57,2 % (n=1187) y el Hem-o-lok® el más utilizado para la ligadura de la base apendicular en el 84,8 % (n=1759) de los pacientes. No se observaron diferencias estadísticamente significativas en la tasa de infección del sitio operatorio, reintervención o íleo. El uso de energía simple redujo los costos del procedimiento de manera significativa durante el período evaluado.
Discusión. El uso de energía monopolar demostró ser una técnica segura, reproducible y de menor costo en comparación con el uso de energía bipolar, independientemente de la fase de la apendicitis aguda. Lo anterior ha permitido que se realicen más apendicectomías por laparoscopia y que los médicos residentes de cirugía general puedan realizar procedimientos laparoscópicos de forma más temprana.

Validity of Appendicitis Inflammatory Response Score in Distinguishing Perforated from Non-Perforated Appendicitis in Children. CHILDREN-BASEL 2021; 8:children8040309. [PMID: 33921577 PMCID: PMC8073718 DOI: 10.3390/children8040309] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 03/28/2021] [Accepted: 04/13/2021] [Indexed: 12/29/2022]
Abstract
Background: This prospective observational study aimed to evaluate the validity of appendicitis inflammatory response (AIR) score in differentiating advanced (perforated) from simple (non-perforated) appendicitis in pediatric patients. Methods: A single-center prospective cross-sectional study was conducted between 1 January 2019 until 1 May 2020 including 184 pediatric patients who underwent appendectomy. Based on the intraoperative finding of advanced (n = 38) or simple (n = 146) appendicitis the patients were divided into two groups. Recipient-operator curve (ROC), with calculation of sensitivity and specificity of best cutoff and the area under the curve (AUC), were used to measure the diagnostic value and the potential for risk stratification of the AIR score, among the patients with simple or advanced acute appendicitis. Results: The median value of the AIR score in the perforated and non-perforated groups was 10 (interquartile range, IQR 9, 11), and was 7 (IQR 6, 9), respectively (p < 0.001). Based on the calculated value of AIR score, the patients were classified with a high precision into low, indeterminate and high risk groups for acute appendicitis (p < 0.001). A cutoff value of ≥9 was demonstrated to serve as a reliable indicator of perforated appendicitis with a sensitivity and a specificity of 89.5% and 71.9%, respectively (AUC = 0.80; 95% CI: 0.719–0.871; p < 0.001). Conclusions: Acute appendicitis can be detected with a high level of sensitivity and specificity using the AIR score. Also, the AIR score may differentiate perforated from non-perforated appendicitis in pediatric patients with a high level of accuracy.

Abstract
Objective To compare the use of ultrasonic dissector and suture ligation for mesoappendix in laparoscopic appendectomy in terms of mean operative time and per-operative bleed. Methodology This was a randomized controlled trial conducted at Surgical Unit II, Holy Family Hospital over a period of six months. All patients with the diagnosis of acute appendicitis who presented in the emergency department of Holy Family Hospital on the call days of Surgical Unit II undergoing laparoscopic appendectomy were included in the study. After taking informed consent about the respective procedure, patients were allocated to two groups using computer-generated random numbers. Group A was operated using harmonic scalpel and in Group B suture ligation was done. Total time required to ligate the mesoappendix or to cauterize it using the harmonic scalpel was measured in minutes. Data was entered and analyzed in SPSS version 21.0 (IBM Corp., Armonk, NY). Results A total of 110 patients were enrolled in the study according to the inclusion criteria of the study. Patients were randomly divided into two equal groups. Patients in Group A were operated using harmonic scalpel whereas patients in Group B were operated by suture ligation for dealing the mesoappendix in laparoscopic appendectomy. Mean operative time to ligate the mesoappendix for Group A patients was 1.56 (SD = 0.68) minutes while that of Group B was 21.07 (SD = 2.84) minutes. There was no per-operative bleeding in case of Group A while its incidence was 24% of patients in Group B. Results were statistically significant. Conclusion The conclusion of the study is that the use of harmonic scalpel was better than suture ligation for ligating the mesoappendix in laparoscopic appendectomy in terms of mean operative time and per operative bleed, hence it's preferable over the later in laparoscopic appendectomy.

Abstract
BACKGROUND The aim of this study was to compare lateral thermal damage of the appendix and clinical outcomes after laparoscopic appendectomy using new versus reused Harmonic scalpels. METHODS A total of 100 consecutive patients with acute appendicitis who underwent laparoscopic appendectomy were enrolled in the two-center, randomized clinical trial. Using a computer random number generator, patients were allocated to new or reused group. Histopathological measurement of lateral thermal damage of the appendiceal base and mesoappendix, speed of transection of the appendiceal base, duration of surgery, subjective rating of device functionality, length of hospital stay, and complications were compared within groups. RESULTS The median lateral thermal damage on the appendiceal base in the new group (N = 49) was 0.2 mm (IQR 0.1-0.2) and 0.1 mm (IQR 0.1-0.3) in the reused group (N = 51) (P = 0.644), while on the mesoappendix for both groups, thermal damage was 0.1 mm (IQR 0.1-0.2) (P = 0.418). The median time required for base transection in both groups was 8 s (IQR 7-9) (P = 0.776). The median duration of surgery was also comparable between the groups (22 min, IQR 20-30 vs 25 min, IQR 21-35; P = 0.233). Two postoperative complications in the new group and one in the reused group were recorded (4% vs 2%; P = 0.536). Surgeons' subjective assessment of the instrument did not reveal significant difference between the groups in all of the investigated categories. CONCLUSIONS The results of our study support the reuse of Harmonic scalpels especially in the settings where economic constraints might hamper access to minimally invasive surgery to a larger number of patients. The results obtained on laparoscopic appendectomy might not be reproducible to other more demanding surgical procedures. TRIAL REGISTRATION ClinicalTrials.gov registry under identifier NCT04226482.

Abstract
INTRODUCTION Healthcare expenditure is on the rise placing greater emphasis on operational excellence, cost containment, and high quality of care. Significant variation is seen in operating room (OR) costs with common surgical procedures such as laparoscopic appendectomy. Surgeons can influence cost through the selection of instrumentation for common surgical procedures such as laparoscopic appendectomy. We aimed to quantify the cost of laparoscopic appendectomy in our healthcare system and compare cost variations to operative times and outcomes. METHODS AND PROCEDURES We performed a retrospective review of laparoscopic appendectomies in a large regional healthcare system during one-year period (2018). Operating room supply costs and procedure durations were obtained for each hospital. The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) outcomes and demographics were compared to the costs for each hospital. RESULTS A total of 4757 laparoscopic appendectomies were performed at 20 hospitals (27 to 522 per hospital) by 233 surgeons. The average supply cost per case ranged from $650 to $1067. Individual surgeon cost ranged from $197 to $1181. The average operative time was 41 min (range 33 to 60 min). There was no association between lower cost and longer operative time. The patient demographics and comorbidities were similar between sites. There were no significant differences in postoperative complications between high- and low-cost centers. The items with the greatest increase in cost were single-use energy devices (SUD) and endoscopic stapler. We estimate that a saving of over $417 per case is possible by avoiding the use of energy devices and may be as high as $ 984 by adding selective use of staplers. These modifications would result in an annual savings of $1 million for our health system and more than $ 125 million nationwide. CONCLUSION Performing laparoscopic appendectomy with reusable instruments and finding alternatives to expensive energy devices and staplers can significantly decrease costs and does not increase operative time or postoperative complications.

Abstract
OBJECTIVE To analyze the role of mesoappendixectomy in the development of intra-abdominal surgical site infection (IAB SSI) after LAE. MATERIAL AND METHODS A prospective randomized non-blind multiple-center registered (ClinicalTrials.gov NCT03754777) study has been performed for the period from 2016 to 2018. The study was devoted to effectiveness and safety of the modified enhanced recovery protocol in LAE. In the main group, this protocol (n=56) included routine mesoappendixectomy, restrictive strategy for abdominal drainage and postoperative antibiotic prevention. In the control group (n=71), mesoappendixectomy was performed only in case of necrotic changes. Both groups were comparable by demographic parameters and severity of comorbidities. RESULTS In the main group, significant decrease in the incidence of IAB SSI was found (0% versus 9.8%). Moreover, the main group was characterized by reduced length of hospital-stay (1.43±1.34 d versus 2.94±2, 43 days). CONCLUSION Mesoappendixectomy should be evaluated in further research as a potential factor in prevention of IAB SSI.

Abstract
OBJECTIVE To improve treatment outcomes in patients with acute appendicitis (AA). MATERIAL AND METHODS An internet survey was performed. Questionnaire consisted of 15 questions concerning diagnosis and treatment of AA: application of prognostic scales, incidence and technical aspects of laparoscopic appendectomy (LA), antibiotic prophylaxis, postoperative management, compliance with international and national clinical guidelines. A total of 690 questionnaires were received and analyzed (3.67% of all surgeons in the Russian Federation). RESULTS Eighteen percent of respondents use at least one prognostic scale. The vast majority of surgeons (92%) use antibiotic prophylaxis. Almost half of respondents place trocars in the triangulation position (44%), one third of surgeons ligate the mesentery of the appendix (35%), most respondents perform mesoappendectomy (60%) with monopolar and bipolar cautery. Forty-five percent of all respondents do not invert the appendix stump. Significant number of respondents use abdominal drainage routinely. Only 3.5% of surgeons use multimodal postoperative analgesia. Less than 22% of patients are operated under low-pressure pneumoperitoneum. Standardization of surgical technique and perioperative approaches including those specified in the guidelines is absent. We also found insufficient awareness of surgeons about international and national clinical guidelines. CONCLUSION This study may be useful for standardizing treatment approaches, choosing the best practice, popularizing and improving of current clinical guidelines.

Abstract
Background Monopolar energy (ME) is routinely used in appendectomy. This study aimed to investigate the degree of lateral thermal spread generated by ME and to evaluate the thermal injury sustained by the close-lying tissues. Methods Appendectomy with a monopolar Maryland dissector was performed in 8 rabbits (at 30 and 60 W power settings). A high-resolution infrared camera was used to record tissue heating during the intervention. After autopsy macroscopic changes were evaluated and tissue samples were subjected to myeloperoxidase (MPO) assay and histological examination. Results No significant differences in the extent of thermal spread, MPO activity and histological signs of inflammation were observed between groups. Regardless of the power settings, the heat spread exceeded 2 cm laterally along the mesoappendix when application time exceeded 3 s. The spread of heat through tubular structures in both groups caused a significant temperature rise in the nearby intestinal loop, resulting in perforation (n = 3) and necrosis (n = 1). Conclusions Application time is critical in thermal spread during appendectomy aided by ME. Tubular anatomic structures can enhance thermal injury on distant tissues. The observed effects of ME bear clinical relevance that need further investigation.

Abstract
BACKGROUND AND AIMS Acute appendicitis (AA) is among the most common causes of acute abdominal pain. Diagnosis of AA is still challenging and some controversies on its management are still present among different settings and practice patterns worldwide. In July 2015, the World Society of Emergency Surgery (WSES) organized in Jerusalem the first consensus conference on the diagnosis and treatment of AA in adult patients with the intention of producing evidence-based guidelines. An updated consensus conference took place in Nijemegen in June 2019 and the guidelines have now been updated in order to provide evidence-based statements and recommendations in keeping with varying clinical practice: use of clinical scores and imaging in diagnosing AA, indications and timing for surgery, use of non-operative management and antibiotics, laparoscopy and surgical techniques, intra-operative scoring, and peri-operative antibiotic therapy. METHODS This executive manuscript summarizes the WSES guidelines for the diagnosis and treatment of AA. Literature search has been updated up to 2019 and statements and recommendations have been developed according to the GRADE methodology. The statements were voted, eventually modified, and finally approved by the participants to the consensus conference and by the board of co-authors, using a Delphi methodology for voting whenever there was controversy on a statement or a recommendation. Several tables highlighting the research topics and questions, search syntaxes, and the statements and the WSES evidence-based recommendations are provided. Finally, two different practical clinical algorithms are provided in the form of a flow chart for both adults and pediatric (< 16 years old) patients. CONCLUSIONS The 2020 WSES guidelines on AA aim to provide updated evidence-based statements and recommendations on each of the following topics: (1) diagnosis, (2) non-operative management for uncomplicated AA, (3) timing of appendectomy and in-hospital delay, (4) surgical treatment, (5) intra-operative grading of AA, (6) ,management of perforated AA with phlegmon or abscess, and (7) peri-operative antibiotic therapy.

Vet Surg 2020; 49:1024-1034. [PMID: 32255208 DOI: 10.1111/vsu.13408] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2019] [Revised: 04/08/2019] [Accepted: 05/19/2019] [Indexed: 11/27/2022]
Abstract
OBJECTIVE To determine the ability of functional side-to-side small intestinal anastomoses (FSS-SIA) created with an electrothermal bipolar vessel sealing (EBVS) device to resist leakage. STUDY DESIGN Experimental, ex vivo. SAMPLE POPULATION Jejunal segments (n = 130) from 10 healthy canine cadavers. METHODS Four types of anastomoses were created (two segments/construct and 15 constructs/group): EBVS (group A), EBVS + transverse stapling (group B), stapled (group C), and EBVS + suture augmentation (group D). Initial leakage pressure (ILP), initial leakage location (ILL), and maximal intraluminal pressure were compared between groups, and five group A constructs were analyzed histologically. RESULTS Initial leakage pressure was greater in group D than in groups A, B, and C (P < .011). There was a difference in ILL among groups (P = .003). Leakage occurred at the side-to-side intestinal anastomosis fusion line in 13 of 15 (87%) constructs for groups A and B and in nine of 15 (60%) constructs for group D. Maximal intraluminal pressure was greater in group C than in groups A, B, and D (P < .004). Histological examination was consistent with collagenous fusion without cavitation defects. CONCLUSION Functional side-to-side small intestinal anastomosis was consistently achieved with an EBVS device. Augmentation of EBVS anastomoses with simple interrupted sutures along the anastomotic fusion line increased ILP compared with stapled anastomoses. CLINICAL SIGNIFICANCE Despite the success and feasibility of creating an FSS-SIA with an EBVS device, additional in vivo studies are required to determine the effectiveness of intestinal fusion prior to clinical implementation.

Abstract
Ultrasonic devices disperse less energy in the tissues. The new Harmonic Focus+ (HF+) seems to be more efficient but thermal damages have been reported. This study examined the temperature and the emissivity profile of the active and passive blades of the HF+, on a pig tissue model at different power settings. The FLIR System B series thermal imaging camera has been used on various biological pig tissues to evaluate the emissivity of the ultrasonic device. The active blade heats up faster than the passive one and the increase in power increases the speed of the temperature raising only on the active blade. Increasing the power setting reduces the dissection time and the temperature of both blades. Active blade temperatures of <60°C are obtained with cutting times close to 5 seconds; with these cutting times, the inactive blade does not exceed 30°C. The HF+ emissivity profiles demonstrate that the behavior of the inactive blade is significantly different from the active one. To prevent thermal damages, keep the active blade toward the operator, do not exceed 5 seconds of activation, use the maximum power, and avoid the use of the instrument as a dissector immediately after its activation.

Abstract
Introduction: Laparoscopic appendectomy is a commonly performed procedure. The base of appendix is secured by various techniques (suture, LigaSure, endoloop, or hamlock clip). Harmonic scalpel (HS) may be used to seal the base of the appendix. The study was conducted to assess the efficacy of HS in laparoscopic appendectomy for sealing the base of the appendix. Materials and Methods: The patients were divided into two groups: group 1 in which base was secured by endoloop and group 2 in which base of the appendix was sealed by HS in a stepwise manner. We made a record of patients' age and gender, and operative time. The patients were followed for a period of 3 months from the time of discharge. Results: During the study period of 4.5 years, 102 patients were in group 1 and 108 patients in group 2. Both groups were age and gender matched. Mean operating time for group 1 was 43.34 ± 6.7 minutes and that for group 2 was 28.46 ± 7.19 minutes (P < .0001). Complications included postoperative ileus (group 1 = 8, group 2 = 10) and surgical site infection (group 1 = 4, group 2 = 4, P > .05). Conclusion: It appears that use of HS for laparoscopic appendectomy is feasible and safe. Its results appear to be comparable with other methods of laparoscopic appendectomy. Complications are minimal. Further studies at other centers may substantiate our efforts.

Abstract
Background Acute appendicitis (AA) is the most common surgical condition in children. Although a higher incidence of AA in summer has been reported, the reason for this observation remains unclear. The purpose of this study was to compare the clinical findings of AA patients who underwent appendectomies during the summer months with those who underwent the procedure during the non-summer months. Methods The clinical data of 171 patients who underwent appendectomy from January 2013 to December 2016 were reviewed. The patients were divided into a summer group (from May to October) and a non-summer group (from November to April) based on the month when appendectomy was performed. All patients were under 18 years of age at the time of surgery. The medical records including laboratory data, computed tomography scans, pathology reports and operative notes were reviewed. Results The number of patients with AA was higher in the summer group than in the non-summer group (101 vs. 70 patients). No significant differences in the laboratory results between the two groups of patients were observed. The percentage of AA patients who presented with a fecalith was significantly lower in the summer group (33.6%) than in the non-summer group (55.7%). No significant differences in the incidence of appendiceal perforations and abscesses, as well as postoperative complications were observed between the two groups. Conclusions The percentage of AA patients with fecaliths in summer was lower than that in the non-summer months. The increase in the number of AA patients in summer may be due to the increased occurrence of lymphoid hyperplasia, which may be correlated with the yearly outbreak of enterovirus infection during this period.

Abstract
Background: The aim of this study is the evaluation of clinical signs and outcomes of treatment in children under five years of age who underwent appendectomy because of acute appendicitis. Patients and Methods: From January 2009 until December 2018, 90 patients (54 boys and 36 girls) younger than five years of age, treated with appendectomy because of acute appendicitis, were included in this study. Patients were divided into two groups, depending on the intra-operative finding of non-perforated (Group I; n = 32) or perforated (Group II; n = 58) appendicitis. The groups were compared regarding demographic, clinical, and laboratory data and outcomes of treatment. Results: Of 1687 appendectomies in this period, 90 (5.3%) of them were performed in patients aged five years or younger. There were 58 (64.4%) patients with perforated appendix. Positive correlation between the rate of perforation and the age of patients was found. Perforation rates were significantly higher in younger patients (100%, <1 year; 100%, 1-2 y; 83.3%, 2-3 y; 71.4%, 3-4 y; 78.6%, 4-5 y, and 47.3%, 5 y) (p = 0.037). Vomiting and diarrhea were found more commonly in the group of perforated appendix (p < 0.002, p < 0.001), while constipation was found more often in the patients whose appendix was not perforated (p < 0.001). The median duration of symptoms (48 h vs. 16 h; p < 0.001) and median duration of hospitalization (7.5 d vs. 5 d; p < 0.001) were notably longer for the group of patients with perforated than the group of patients with non-perforated appendix. All complications occurred in the group of perforated appendix with total incidence of 4.4%. Conclusion: The clinical presentation of acute appendicitis for children aged five years or younger is often unusual, and establishing the proper diagnosis is often delayed. Patient age is tied closely to the stage of acute appendicitis, so the youngest patients present with more advanced stages of disease and are at greater risk of perforation. Acute appendicitis should be considered in all cases where a child is having abdominal pain, fever, and diarrhea, which has been shown to be present significantly more often in children with perforated appendix.

Abstract
This study examined the safety and usefulness of minimally invasive surgery (MIS) for malignant abdominal tumors in pediatric patients and analyzed the factors affecting the resection margin, operative time, and hospital stay of neuroblastoma (NBL) patients.We retrospectively reviewed data of pediatric patients who underwent MIS for malignant abdominal tumors from January 2011 to June 2017 at the Seoul National University Children's Hospital. Sex; age at operation; diagnosis; tumor location; operation-related data, such as operation time and transfusion; and follow-up data were reviewed. We divided patients into an excision group and a biopsy group. Detailed pathologic data were reviewed to analyze factors affecting the resection margin of NBL. Median value and range were calculated for all continuous variables. Mann-Whitney test and χ test were used as appropriate. P values of <.05 were considered significant.Thirty-four pediatric patients were included; 21 were boys. The median age was 4 (0.2-18) years. The most common diagnosis was NBL (17 patients; 50.0%). Three patients each were diagnosed with lymphoma, solid pseudopapillary tumor of the pancreas, and teratoma. The median tumor size was 3.4 (0.5-10.2) cm. The median operation time was 108 (55-290) minutes, and the median hospital stay was 5 (2-11) days. The number of conversions to open surgery was 4. There were no postoperative complications or mortality. There were 18 patients in the excision group and 16 in the biopsy group. Diagnosis and the number of patients receiving preoperative chemotherapy differed between the 2 groups. R0 resection of NBL was significantly higher in patients with stage 1 disease and those aged >2 years. There were no clinical factors influencing operative time or hospital stay.MIS was feasible and safe in pediatric patients with malignant abdominal tumors. R0 resection of NBL was related to age and stage.

Abstract
Background We performed an umbrella review of systematic reviews summarizing the evidence on the Harmonic scalpel (HS) compared with conventional techniques in surgical oncology (including lymph node dissection). Methods We searched MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews from inception to end of March of 2017 for meta-analyses or systematic reviews of randomized trials comparing HS to conventional techniques in surgical oncology. We assessed the quality of included systematic reviews with AMSTAR (A MeaSurement Tool to Assess systematic Reviews) and assessed the certainty in evidence for each pooled outcome using GRADE (Grading of Recommendations Assessment, Development, and Evaluation). Results We identified ten systematic reviews on breast cancer (n = 3), gastric cancers (n = 3), oral, head, and neck cancers (n = 1), and colon cancers (n = 3). Most reviews received a higher rating using AMSTAR. For operative time, systematic reviews reported a reduction of 25 to 29 min for HS compared with conventional methods across oncology types, with the exception of breast cancer where little differences were observed (very low to moderate quality of evidence (GRADE)). For blood loss and drainage volume, the majority of reviews reported statistically significant reductions with HS, and reductions ranged from 42 to 141 mL, and from 42 to 292 mL, respectively (very low to moderate quality of evidence). Hospitalization days were reported to decrease with use of HS by 0.2 to 3.2 days; however, reductions were only statistically significant for half of the included reviews (low to moderate quality of evidence). Regarding perioperative complications, two of six reviews reported a significantly reduced risk with HS use (breast cancer surgery) (moderate to high quality evidence)). Conclusion Across surgical oncology types, the majority of included systematic reviews showed a statistically significant or numerical improvement in surgical outcomes with use of the HS compared with conventional methods. Well-designed randomized studies with large sample sizes will help to provide more precise estimates and reduce the risk of heterogeneity.
