Improved outcomes for laparoscopic appendectomy compared with open appendectomy in the pediatric population

Postoperative Pain Management in Children Undergoing Laparoscopic Appendectomy: A Scoping Review

Laparoscopic appendectomy (LA) is one of the most commonly performed surgical procedures in children and is associated with extreme postoperative discomfort due to peritoneal inflammation and infection. The main objective of this study was to investigate the effects of postoperative pain (POP) in children after laparoscopic appendectomy. Articles describing or evaluating the control of POP in children with LA were considered eligible. All available literature such as randomized controls, prospective controls, retrospective as well as clinical studies were considered. A comprehensive search was performed in PubMed, Medline, Embase, Cochrane Library, Clinical trials.gov, and Google scholar. The initial search took place on 23 April 2021, and was updated on 24 August 2021. There were no language or date restrictions. Each of the included articles was evaluated separately by two independent reviewers. Additional papers were found by searching the reference lists of eligible studies. Eighteen papers were considered. All papers, and many of them used different methods to treat POP in children undergoing LA, such as lidocaine infusion, different analgesic approaches, ultrasound-guided transverse abdominis blockade (UGTAP), ultrasound-guided quadratus lumborum blockade (UGQLB), and comparison of open appendectomy (OA) with local anesthetics in relation to POP management in children. Laparoscopic appendectomy is the surgical procedure preferred by clinicians compared with open appendectomy in children. A multimodal analgesic approach is optimal and efficient surgical techniques such as UGBRSB, UGQLB, and UGTAP block might significantly impact POP in children except that there are contraindications. Dexmedetomidine proved to be an effective adjuvant that can enhance the effect of local anesthetics. The lack of a sufficient number of studies may be a factor affecting our confidence in the results of this study. Therefore, further evidence-based randomized control trials with a large sample size are needed to provide clarity.

The analgesic effect of the intravenous administration of acetaminophen for pediatric laparoscopic appendectomy: A comparison of scheduled and on-demand procedures

PURPOSE

The intravenous administration of acetaminophen (IAA) has become standard postoperative analgesic management for pediatric surgery. However, the most effective methods of IAA for postoperative acute appendicitis are unclear. We evaluated the analgesic efficacy of scheduled IAA vs on-demand IAA for postoperative acute appendicitis.

METHODS

Ninety-four patients who underwent laparoscopic appendectomy in our institution between January 2017 and December 2020 were enrolled. The patients were divided into two groups based on the postoperative pain control protocols. The scheduled IAA group (SA group, n = 42) was managed by scheduled IAA and additional on-demand use of pentazocine as rescue therapy. The on-demand IAA group (ODA group, n = 52) was managed by on-demand IAA as the first choice, with pentazocine as the second choice for pain control. The patients' background characteristics, operative results and postoperative outcomes were reviewed.

RESULTS

The number of times pain complaints were made per patient per day (NPPD) on postoperative days (POD) 1 and 2 was significantly lower in the SA group than in the ODA group (POD 1; 1.12 ± 1.21 vs 2.62 ± 1.89, p < 0.01; POD 2; 0.45 ± 0.86 vs. 1.31 ± 1.69, p < 0.01). According to pathological findings, NPPD was lower in the SA group than in the ODA group for both phlegmonous appendicitis (0.71 ± 1.01 vs. 2.10 ± 2.13, P < .05) and gangrenous appendicitis (1.33 ± 1.50 vs 2.94 ± 1.68, P < .01). On POD 2, the incidence of gangrenous appendicitis was significantly lower in the SA group than in the ODA group (0.57 ± 0.93 vs 1.78 ± 1.86, P < .01).

CONCLUSIONS

Scheduled IAA may have favorable efficacy for postoperative pain control after emergency surgery for acute appendicitis in pediatric patients.

Laparoscopic versus Open Pediatric Surgery: Three Decades of Comparative Studies

INTRODUCTION

 Despite its wide acceptance, the superiority of laparoscopic versus open pediatric surgery has remained controversial. There is still a call for well-founded evidence. We reviewed the literature on studies published in the last three decades and dealing with advantages and disadvantages of laparoscopy compared to open surgery.

MATERIALS AND METHODS

 Studies comparing laparoscopic versus open abdominal procedures in children were searched in PubMed/MEDLINE. Reports on upper and lower gastrointestinal as hepatobiliary surgery and on surgery of pancreas and spleen were included. Advantages and disadvantages of laparoscopic surgery were analyzed for different types of procedures. Complications were categorized using the Clavien-Dindo classification.

RESULTS

 A total of 239 studies dealing with 19 types of procedures and outcomes in 929,157 patients were analyzed. We identified 26 randomized controlled trials (10.8%) and 213 comparative studies (89.2%). The most frequently reported advantage of laparoscopy was shorter hospital stay in 60.4% of studies. Longer operative time was the most frequently reported disadvantage of laparoscopy in 52.7% of studies. Clavien-Dindo grade I to III complications (mild-moderate) were less frequently identified in laparoscopic compared to open procedures (80.3% of studies). Grade-IV complications (severe) were less frequently reported after laparoscopic versus open appendectomy for perforated appendicitis and more frequently after laparoscopic Kasai's portoenterostomy. We identified a decreased frequency of reporting on advantages after laparoscopy and increased reporting on disadvantages for all surgery types over the decades.

CONCLUSION

 Laparoscopic compared with open pediatric surgery seems to be beneficial in most types of procedures. The number of randomized controlled trials (RCTs) remains limited. However, the number of reports on disadvantages increased during the past decades.

Children's Opioid Use at Home After Laparoscopic Appendectomy

BACKGROUND

To combat the opioid epidemic, prescribers need accurate information about pediatric home opioid requirements to manage acute pain after surgery. Current opioid use estimates come from retrospective surveys; this study used medication adherence technology (eCAP) to track home opioid use.

PURPOSE

To describe children's pain treatment at home after laparoscopic appendectomy, and to compare self-reported opioid analgesic use to eCAP data and counts of returned pills.

DESIGN

Prospective exploratory and descriptive study METHODS: A convenience sample of 96 patients, 10-17 years of age, from a single urban nonprofit children's hospital consented to self-report pain treatment in 14-day diaries and use eCAP to monitor prescribed opioid use at home after laparoscopic appendectomy.

RESULTS

Patients were prescribed 5-45 opioid-containing pills (mean ± standard deviation 15 ± 7.2). Of 749 opioid-containing pills prescribed to 49 patients who returned data, 689 pills were dispensed, 167.5 were used for the reason prescribed, 488 were returned to families for disposal, and 53.5 were missing. The majority of the 49 patients were opioid naïve (72%), Caucasian (64%), and male (56%), with a mean age of 14 years. Patients used 6.6 ± 6.3 opioid-containing pills by pill count and 5.6 ± 5.1 by self-report, a significant difference (p = .004). Unreported eCAP-enabled pill bottle openings typically occurred on weekends.

CONCLUSION

Medication adherence technology (eCAP) is a more rigorous method than self-report to estimate opioid needs and detect early opioid misuse. Additional rigorously designed studies of postoperative opioid use are needed to guide opioid prescribing.

Laparoscopic Appendectomy in Children With Perforated Appendicitis: A Meta-Analysis

BACKGROUND

The purpose of this meta-analysis was to compare the influence of different surgical procedures on perforated appendicitis in pediatric population.

MATERIALS AND METHODS

Studies were identified through a computerized literature search of Pubmed, Embase, Ovid, the Cochrane Colorectal Cancer Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials, the Cochrane Library database, and Web of Science. Two reviewers independently assessed the quality of each study and abstracted outcome data. Data were extracted comparing laparoscopic appendectomy (LA) and open appendectomy (OA) in pediatric population with regard to several postoperative variables. We synthesized published data using fixed-effect models, expressing results as relative risk (RR).

RESULTS

Nine eligible studies were included which came from various medical centers all over the world. Statistically significant differences between "LA" and "OA" groups were found for wound infection (RR=0.88), intra-abdominal abscess (RR=1.38), and bowel obstruction (RR=0.79).

CONCLUSIONS

Our meta-analysis found that LA is associated with lower incidence of wound infections and bowel obstruction, but the rate of intra-abdominal abscess was higher than OA.

Efficacy of Analgesic Treatments to Manage Children's Postoperative Pain After Laparoscopic Appendectomy: Retrospective Medical Record Review

Knowledge of the effectiveness of multimodal analgesic treatments to manage children's postoperative pain during hospital stays is limited. Our retrospective chart review of a convenience sample of 200 pediatric surgical patients' pain experiences during the first 24 hours after laparoscopic appendectomy demonstrates the benefits of a multimodal analgesic approach. We found that pediatric patients who received perioperative IV ketorolac in addition to opioids reported statistically significantly lower mean pain intensity (n = 134, mean [M] = 2.9, standard deviation [SD] = 1.7) during the first 24 hours after surgery when compared with the pain intensity of patients who did not receive perioperative IV ketorolac (n = 66, M = 3.7, SD = 1.7, t = 3.14, P = .002). Patients who received perioperative IV ketorolac (M = 0.94, SD = 0.71) also received significantly fewer morphine equivalents of postoperative opioids during the first 24 hours after surgery than those who did not (M = 1.21, SD = 0.78, t = 2.41, P = .02). We will use data from these patients to introduce the potential for a personalized medicine approach to postoperative pain.

Predicting Postoperative Complications After Pediatric Perforated Appendicitis

PURPOSE

Assessment of risk factors for postoperative complications following surgical treatment of pediatric perforated appendicitis (PA) is necessary to identify those patients in need of closer monitoring. In this study, we have investigated the impact of different risk factors on the occurrence of complications after an appendectomy in children with PA.

MATERIAL AND METHODS

The study was a retrospective, single-centre analysis of all pediatric PA conducted over a 10-year period. Preoperative clinical and laboratory results, intraoperative findings, and postoperative complications were analyzed. Risk factors were defined and a risk score was determined for postoperative complications and reinterventions.

RESULTS

Surgical treatment for appendicitis was performed in 840 pediatric patients during the observation period. 163 of the included patients were diagnosed with PA (mean age 8.9 ± 3.6 years). 19 (11.7%) patients developed postoperative complications, 17 (10.4%) of which required complication-related intervention. We identified five predictors of postoperative complications: the C-related protein value at admission, purulent peritonitis, open appendectomy (primary, secondary, or converted), placement of an abdominal drain, and administration of antibiotics not compliant to results from the subsequent antibiogram. The determined risk score was significantly higher in the complication group (p < .0001) and reintervention group (p < .001).

CONCLUSIONS

Postoperative complications following pediatric PA can be predicted using specific preoperative, intraoperative, and postoperative risk factors. In the high-risk group, an active prevention, detection, and intervention of any occurring complication is necessary and we present a new specific pediatric risk score to define patients at risk for complications.

National trends in therapeutic approaches and outcomes for pediatric appendicitis: a Taiwanese nationwide cohort study

PURPOSE

To define the pattern of therapeutic approaches for pediatric appendicitis and compare their benefits in Taiwan, we analyzed a research-oriented dataset released by the Bureau of National Health Insurance in Taiwan through the Collaboration Center for Health Information Application (CCHIA) to document the impact of the rise of laparoscopic treatment on outcomes.

METHODS

We identified 22,161 patients under 18 years who had been hospitalized with a diagnosis of acute appendicitis between 2007 and 2012 in the CCHIA. Statistical comparisons between the Laparoscopic appendectomy (LA) and open appendectomy (OA, control) groups were computed using a Chi squared test. The odds ratios (ORs) and 95% confidence intervals (CIs) of risk factors for intra-abdominal abscess (IAA) and postoperative bowel obstruction (PBO) were derived from multivariate logistic regression models.

RESULTS

In each respective year, the incidence of LA increased from 29.17% in 2007 to 57.4% in 2012, while that of OA decreased from 70.83% in 2007 to 42.60% in 2012; incidences of non-perforated appendicitis and perforated appendicitis with LA or OA seemed similar. The length of hospitalization between an LA and OA for non-perforated appendicitis was the same, but that with an LA was shorter for perforated appendicitis. The adjusted ORs for IAA and PBO for those patients with perforated and non-perforated appendicitis were 6.30 (95% CI = 5.09-7.78; p < 0.001) and 6.49 (95% CI = 4.45-9.48; p < 0.001); while for those cases undergoing an LA and OA, they were 0.50 (95 % CI = 0.40-0.62; p < 0.001) and 2.07 (95% CI = 1.45-2.95; p < 0.001), respectively. The ORs of IAA and PBO for those patients ≤6 and 7-12 years of age were 1.67 (95% CI = 1.23-2.25; p = 0.001) and 1.20 (95% CI = 0.97-1.49; p = 0.095), and 1.88 (95% CI = 1.08-3.24; p = 0.025) and 1.47 (95% CI = 1.01-2.14; p = 0.043), respectively, compared to those aged 13-18 years.

CONCLUSIONS

Our study demonstrated that young age and perforated appendicitis can affect postoperative IAA and PBO. LA appeared beneficial in reducing the length of hospitalization and postoperative IAA, but had an increasing risk of PBO. Although laparoscopic approach for pediatric appendectomy is increasing in our country, the different hospital levels and pediatric surgeon's laparoscopic experience must be evaluated in further study.

Laparoscopic treatment of perforated appendicitis

The use of laparoscopy has been established in improving perioperative and postoperative outcomes for patients with simple appendicitis. Laparoscopic appendectomy is associated with less wound pain, less wound infection, a shorter hospital stay, and faster overall recovery when compared to the open appendectomy for uncomplicated cases. In the past two decades, the use of laparoscopy for the treatment of perforated appendicitis to take the advantages of minimally invasiveness has increased. This article reviewed the prevalence, approaches, safety disclaimers, perioperative and postoperative outcomes of the laparoscopic appendectomy in the treatment of patients with perforated appendicitis. Special issues including the conversion, interval appendectomy, laparoscopic approach for elderly or obese patient are also discussed to define the role of laparoscopic treatment for patients with perforated appendicitis.

Laparoscopic appendectomy in children: experience in a single centre in chittagong, bangladesh

Background. Since the latter half of 1980s laparoscopy has become a well accepted modality in children in many surgical procedures including appendectomy. We present here the experience of laparoscopic appendectomy in children in a tertiary care hospital in Bangladesh.  Subjects & Methods. From October 7, 2005 to July 31, 2012, 1809 laparoscopic appendectomies were performed. Laparoscopy was performed in all the cases using 3 ports. For difficult and adherent cases submucosal appendectomy was performed. Feeding was allowed 6 h after surgery and the majority was discharged on the first postoperative day. The age, sex, operative techniques, operative findings, operative time, hospital stay, outcome, and complications were evaluated in this retrospective study. Results. Mean age was 8.17 ± 3.28 years and 69% were males. Fifteen percent were complicated appendicitis, 8 cases needed conversion, and 27 cases were done by submucosal technique. Mean operating time was 39.8 ± 14.2 minutes and mean postoperative hospital stay was 1.91 days. About 5% cases had postoperative complications including 4 intra-abdominal abscesses. Conclusions. Laparoscopic appendectomy is a safe procedure in children even in complicated cases.

Comparison of clinical outcomes of open, laparoscopic and single port appendicectomies

INTRODUCTION

Appendicectomy is the most common surgical procedure performed in general surgery. This study aimed to compare the outcomes of open appendicectomy (OA), laparoscopic appendicectomy (LA) and single port laparoscopic appendicectomy (SPLA).

METHODS

Fifty consecutive patients with suspected acute appendicitis were studied (OA: n=20, LA: n=20, SPLA: n=10). Clinical outcomes were compared between the three groups in terms of operative time, blood loss, postoperative complications, length of hospital stay and cost.

RESULTS

Patient demographics were similar among groups (p>0.05). SPLA was characterised by longer operative time (88.1 minutes vs 35.6 minutes in OA and 33.4 minutes in LA) and higher costs (12.84 thousand Chinese yuan [RMB] vs 8.41 thousand RMB in LA and 4.99 thousand RMB in OA). OA was characterised by more blood loss (9.8ml vs 7.5ml in SPLA and 6.8ml in LA), longer hospital stay (7.5 days vs 3.5 days in LA and 3.4 days in SPLA) and lower costs. The total number of complications was higher for OA (n=2) than for LA and SPLA (n=0) although this was not statistically significant.

CONCLUSIONS

Where feasible, LA should be undertaken as the initial treatment of choice for most cases of suspected appendicitis.

A retrospective study of multimodal analgesic treatment after laparoscopic appendectomy in children

BACKGROUND

Laparoscopic appendectomy is a common emergency pediatric surgery procedure accompanied by substantial pain (pain scores >4 for >60% of the time) in 33% of these patients. We introduced a bundle of pain management interventions including local anesthetic infiltration at the incision site, intravenous (IV) opioids by patient-controlled analgesia (PCA), and scheduled doses of IV ketorolac and oral acetaminophen/hydrocodone.

OBJECTIVES

To evaluate the effect of these pain management interventions on pain control after laparoscopic appendectomy.

METHODS

We retrospectively studied pain in 206 children above 7 years of age undergoing laparoscopic appendectomy from December 2011 to February 2012 at our institution. We extracted data on patient demographics, duration of anesthesia and surgery, intraoperative opioids, local anesthetic infiltration, surgical procedure reports, along with pain scores, postoperative PCA use, and opioid-related complications and hospital stays. Patients were divided into two groups - simple appendicitis without peritonitis and appendicitis with generalized peritonitis.

RESULTS

The incidence of substantial pain when the multimodal regimen was used was 12%, which is significantly lower than earlier reports (Fisher's exact test P < 0.001). Patients with generalized peritonitis experienced more pain, consumed more opioids, had more unmet PCA demands, and a higher incidence of respiratory depression compared with those with simple appendicitis.

CONCLUSION

The multimodal regimen of local anesthetic infiltration, opioid by PCA, NSAIDs, and oral acetaminophen/hydrocodone reduced the incidence of substantial pain. Additional studies are required to identify subgroups of patients with minimal opioid requirements who can benefit from modifications of this regimen.

Laparoscopic appendectomy: quality care and cost-effectiveness for today's economy

BACKGROUND

Open appendectomy (OA) has traditionally been the treatment for acute appendicitis (AA). Beneficial effects of laparoscopic appendectomy (LA) for the treatment of AA are still controversial.

AIM

To present our technique for LA and to determine whether LA should be the technique of choice of any case of AA instead of OA.

MATERIAL AND METHODS

All cases operated for AA (February 2011 through February 2012) by means of LA or OA were prospectively evaluated. Data regarding length of stay, complications, emergency department consultation after discharge or readmission were collected. Patients were classified into four groups depending on the severity of the appendicitis. Economic data were obtained based on the cost of the disposable material. Cost of hospital stay was calculated based on the Ley de Tasas of the Generalitat Valenciana according to the DRG and the length of stay.

RESULTS

One hundred and forty-two cases were included. Ninety-nine patients underwent OA and 43 LA. Average length of stay for LA group was 2,6 days and 3,8 for OA. Average cost of the stay for OA was 1.799 euros and 1.081 euros for LA. Global morbidity rate was 16%, 5% for LA and 20% for OA.

CONCLUSIONS

LA is nowadays the technique of choice for the treatment of AA.

Laparoscopic appendectomy for perforated appendicitis in children has complication rates comparable with those of open appendectomy

PURPOSE

To evaluate the outcome of laparoscopic (LA) vs. open appendectomy (OA) in children with perforated appendicitis (PA).

METHODS

We reviewed the medical files of 221 children who underwent LA (n=75), OA (n=122), and conversion (CO) (n=24), comparing duration of operation, re-admissions, re-operations, intra-abdominal abscesses (IAA), and wound infections.

RESULTS

Compared to OA, LA resulted in fewer re-admissions (1.3% vs. 12.3%; P=.006), fewer re-operations (4% vs. 17.2%; P=.006), and fewer wound infections (0% vs. 11.5%; P=.001). No differences in the duration of operation (72.9 ± 23.0 min vs. 77.7 ± 48.0 min; P=.392) or IAA (4% vs. 11.5%; P=.114) were observed. Compared to LA, CO had more complications.

CONCLUSIONS

We report that LA is superior to OA with regard to incidence of re-admission, re-operation, and wound infection.

National trends in approach and outcomes with appendicitis in children

BACKGROUND/PURPOSE

Appendicitis is one of the most common surgical conditions in children. Laparoscopy has become the standard approach to appendectomy over the past decade. Some critics cite a lack of evidence documenting clear advantages to laparoscopy. To define the pattern of approach compared to outcomes in the United States, we analyzed the Pediatric Health Information System (PHIS) database to document the impact on outcomes with the rise in laparoscopy.

METHODS

After IRB approval, we queried the PHIS database for all patients over 12 years. The percentages of cases performed open (OA) and laparoscopically (LA) were established for each year. Annual complication percentages were identified for wound infection, intra-abdominal abscess, subsequent laparotomy, and obstruction. For each complication, trend comparisons between LA and OA were made with generalized linear models.

RESULTS

There were 111,194 appendectomies with a positive trend in percentage of laparoscopy from 1999 (22.2%) to 2010 (90.8%), P<0.0001. Over 12 years, there were significant differential trends between LA and OA in rates of wound infection, abscesses, bowel obstructions, and laparotomies within 30 days (P<0.0001 for each). There was no trend in wound infection rates within OA over time (P=0.31), while there was a decrease in infection rates within LA over time (P<0.0001).

CONCLUSIONS

On the basis of a national database analysis, laparoscopy has increased for appendectomy in children over the past 12 years and is associated with a significant decrease in post-operative complications.

Laparoscopic versus open appendectomy in the management of all stages of acute appendicitis in children: a retrospective study

BACKGROUND

We conducted this study in order to evaluate whether laparoscopic appendectomy was an alternative therapeutic tool to open appendectomy for all stages of pediatric appendicitis.

MATERIALS AND METHODS

Between January 2000 and November 2004, the charts of 177 children who underwent appendectomy by a single surgeon were reviewed. The patients were divided into open and laparoscopic appendectomy groups. Each group was subdivided into three stages: simple appendicitis, perforated appendicitis, and appendicitis with abscess. The age, gender, white blood cell count, absolute neutrophil count, C-reactive protein, operating time, duration of postoperative hospital stay, minor and major complications, and use of intravenous analgesia were recorded. Fisher's exact and Student's t-test were used for statistical analysis.

RESULTS

There were fewer minor complications (9/32 vs. 0/20, p = 0.009) in perforated appendicitis stage and fewer major complications (9/26 vs. 1/24, p = 0.011) in appendicitis with abscess stage between open and laparoscopic appendectomy group. But surgery for each laparoscopic appendectomy group took longer to perform than for the corresponding open appendectomy group in each stage (p < 0.05). There was no significant difference in other data between corresponding groups in each stage.

CONCLUSION

Laparoscopic appendectomy may be considered a better alternative to open appendectomy for children with perforated appendicitis and appendicitis with abscess.

Substantial postoperative pain is common among children undergoing laparoscopic appendectomy

BACKGROUND

Laparoscopic appendectomy is one of the most common surgical procedures performed in children. However, to our knowledge, the postoperative pain experience of children undergoing laparoscopic appendectomy has never been described. In this study, we assessed the postoperative pain experience of children undergoing laparoscopic appendectomy.

METHODS

A retrospective chart review of children aged 9-17 years undergoing laparoscopic appendectomy at a large academic medical center from 2004 to 2010 was performed. Demographic and clinical characteristics and self-reported pain scores (0-10 numeric rating scale) during hospitalization were abstracted from the medical record. Pain scores ≥4 were classified as moderate or severe. If ≥60% of pain ratings were moderate or severe during a specified time period (e.g., particular postoperative day), then the child was defined as experiencing substantial pain during that time. Pain outcomes were summarized using descriptive statistics. Secondary analyses assessed the predictors of substantial postoperative pain.

RESULTS

Hundred and eighty-six children underwent laparoscopic appendectomy during the study period. One in three children experienced substantial postoperative pain on the day of surgery, and one in five children continued to have substantial pain the next day. Commonly available clinical and demographic characteristics were poor predictors of substantial postoperative pain.

CONCLUSION

These preliminary data suggest that substantial postoperative pain is common in children undergoing laparoscopic appendectomy. More studies of postoperative pain outcomes among children undergoing laparoscopic appendectomy and other common pediatric surgical procedures are needed.

The evolution of the appendectomy: from open to laparoscopic to single incision

Beginning with its initial description by Fitz in the 19th century, acute appendicitis has been a significant long-standing medical challenge; today it remains the most common gastrointestinal emergency in adults. Already in 1894, McBurney advocated for the surgical removal of the inflamed appendix and is credited with the initial description of an Open Appendectomy (OA). With the introduction of minimally invasive surgery, this classic approach evolved into a procedure with multiple, smaller incisions; a technique termed Laparoscopic Appendectomy (LA). There is much literature describing the advantages of this newer approach. To name a few, patients have significantly less wound infections, reduced pain, and a reduction in ileus compared with the OA. In the past few years, Single Incision Laparoscopic Appendectomy (SILA) has gained popularity as the next major evolutionary advancement in the removal of the appendix. Described as a pioneer in the era of "scarless surgery," it involves only one transumbilical incision. Patients are postulated to have reduced post-operative complications such as infection, hernias, and hematomas, as well as a quicker recovery time and less post-operative pain scores, in comparison to its predecessors. In this review, we explore the advancement of the appendectomy from open to laparoscopic to single incision.

Laparoscopic appendectomy: new concepts

Over the last three decades more surgeons have used laparoscopic appendectomy as their surgical approach of choice in the management of patients with appendicitis. This includes special groups of patients, namely, pediatric, pregnant, and obese patients. Laparoscopy has the benefit of lower morbidity, decreased rate of wound complications, faster recovery, shorter length of hospital stay, and faster return to work over open appendectomy.

Single-incision laparoscopic appendectomy vs multiport laparoscopic appendectomy in children: a retrospective comparison

BACKGROUND

Minimally invasive surgery is commonly used to treat appendicitis. Single-incision laparoscopic surgery is an attractive modality to treat a commonly occurring problem with the advantage of minimal or possibly no scarring. We sought to compare our results of single-incision laparoscopic appendectomy (SILA) with those of patients undergoing traditional multiport laparoscopic appendectomy (MPLA).

PATIENTS AND METHODS

A retrospective review of all patients who underwent a minimally invasive appendectomy from September 2009 to February 2010 was performed. The patients were divided into 2 groups based on if they had a SILA or a traditional MPLA. Outcomes including demographics, diagnosis, operative time, length of stay, narcotic usage, and complications were evaluated.

RESULTS

A total of 110 patients underwent appendectomy. There were 50 patients who underwent SILA and 46 patients who underwent MPLA. Fourteen patients with perforated appendicitis were excluded. Mean age (11.1 vs 11.7 years, P = .43), weight (43.3 vs 50.9 kg, P = .27), and length of stay (1.1 vs 1.2 days, P = .56) were comparable between both groups. Operative time for SILA was slightly longer (33.8 vs 26.8 minutes, P = .01). Overall intravenous narcotic use was lower in the SILA group (0.9 vs 1.4 doses, P = .01), but there was no difference in the patients who also received ketorolac (0.8 vs 1.0 doses, P = .6). Four patients in the SILA group developed superficial wound infections and 1 patient in the SILA group was admitted for postoperative abscess.

CONCLUSIONS

Single-incision laparoscopic appendectomy is safe and effective in the pediatric population. Further studies should be performed to determine the impact on operative time and postoperative narcotic requirements.

[The pediatric surgeon and acute appendicitis]

The management of acute appendicitis in the pediatric patient has undergone radical rethinking in recent years. It has been shown that simple uncomplicated acute appendicitis can be successfully managed with antibiotic therapy and may not even require interval appendectomy. Appendicitis complicated by perforation, abscess, or inflammatory phlegmon can be successfully treated by initial antibiotic therapy (with or without percutaneous drainage) and delayed interval appendectomy. While the laparoscopic approach has proved to be well-adapted to many other pediatric surgical procedures, its utility in the treatment of uncomplicated acute appendicitis remains open to debate; compared to standard open appendectomy, it offers only minimal advantages with regard to post-operative care, length of hospital stay, and complications. Children can be managed either by general surgeons or pediatric surgeons depending on the organization of the emergency service; there may be a higher incidence of removal of a normal appendix in non-specialized services.

Recent advances and controversies in pediatric laparoscopic surgery

Children represent a unique group of patients who are likely to greatly benefit from minimally invasive surgery (MIS). The promise of less postoperative pain, smaller scars, shorter hospital stays, and a faster return to school continues to drive growth in this area. The development of pediatric-specific techniques and documentation of improved outcomes form a critical gateway to widespread application of pediatric MIS. A brief perspective on current approaches to MIS for pediatric congenital and acquired disease is provided in this report. Technical departures from standardized adult MIS and the rationale for their modification are highlighted.

The effectiveness of aerosolized intraperitoneal bupivacaine in reducing postoperative pain in children undergoing robotic-assisted laparoscopic pyeloplasty

OBJECTIVE

To assess the effectiveness of aerosolized intraperitoneal bupivacaine in reducing postoperative pain in children. Laparoscopic surgery has decreased the severity of postoperative pain in children. However, children often experience abdominal and shoulder pain requiring significant amounts of opioids, potentially prolonging their hospitalization.

METHODS

Forty-one consecutive patients undergoing unilateral robotic-assisted pyeloplasty between December 2005 and December 2007 were retrospectively reviewed to assess perioperative opioid requirements and length of hospitalization.

RESULTS

In addition to standard-of-care perioperative analgesia, five patients received intraperitoneal aerosolized bupivacaine just prior to trocar removal, 17 patients received aerosolized bupivacaine just prior to incising the perirenal fascia, and 19 patients received no intervention. There was a significant reduction in postoperative opioid utilization when bupivacaine was administered at the beginning of the surgery (0.1mg/kg vs 0.4mg/kg, P=0.04), but not at the end (0.3mg/kg, P=0.25), as compared to controls. All patients receiving aerosolized bupivacaine had a significantly shorter time in hospital (2.4 vs 1.4 days, P=<0.01).

CONCLUSIONS

The administration of intraperitoneal aerosolized bupivacaine just prior to incising the perirenal fascia appears to be a simple, effective and low-cost method to reduce postoperative pain in children undergoing laparoscopic pyeloplasty.

Assessment of pain by face scales after gastrectomy: comparison of laparoscopically assisted gastrectomy and open gastrectomy

BACKGROUND

Laparoscopic gastrectomy is reported to cause little pain. However, only the total number of analgesics used has been studied to date. Because pain is a subjective experience, its evaluation requires indicators for the subjective assessment.

METHODS

Pain was evaluation for patients after open distal gastrectomy (ODG, 52 cases), laparoscopically assisted distal gastrectomy (LADG, 112 cases), open total gastrectomy (OTG, 18 cases), and laparoscopically assisted total gastrectomy (LATG, 33 cases). The patients were administered continuous epidural anesthesia for 2 days after the surgery. The Wong-Baker FACES pain rating scale was used to evaluate the differences in pain. Each patient was evaluated from postoperative day (POD) 1 to POD 7, and temporal changes in pain were studied comparatively between ODG and LADG and between OTG and LATG.

RESULTS

Peak pain scores were recorded on POD 3 for both distal and total gastrectomy. The scores decreased over time after POD 3. There was no significant difference in scores between open and laparoscopic gastrectomy up to POD 2, but lower scores were shown on PODs 3, 4, and 5 for LADG and on days 3 and 4 for LATG.

CONCLUSIONS

The pain score for laparoscopic gastrectomy was low. There was no significant difference in pain between procedures while epidural anesthesia was in effect. Pain subsided earlier with laparoscopic than with open gastrectomy. The same characteristics were observed with both LADG and LATG.
