Laparoscopic Appendectomy For Acute Appendicitis Research Articles

Appendiceal neoplasms derived from appendiceal tip remnants following appendectomy: a report of two cases

BackgroundNeoplasms derived from remnant appendix are rarely described, with most cases arising from the appendiceal “stump”. Here, we present two surgical cases of appendiceal neoplasms derived from appendiceal “tip” remnants.Case presentationThe first patient was a 71-year-old man who had undergone laparoscopic appendectomy for acute appendicitis 12 years prior. During appendectomy, the appendiceal root was ligated, but the appendix was not completely removed due to severe inflammation. At the most recent presentation, computed tomography (CT) was performed to examine choledocholithiasis, which incidentally revealed a cystic lesion of approximately 90 mm adjacent to the cecum. A retrospective review revealed that the cystic lesion had increased in size over time, and laparoscopic ileocecal resection was performed. Pathology revealed no continuity from the appendiceal orifice to the cyst, and a diagnosis of low-grade appendiceal mucinous neoplasm (LAMN) was made from the appendiceal tip remnant. The patient was discharged without complications. The second patient was a 65-year-old man who had undergone surgery for peritonitis due to severe appendicitis 21 years prior. During this operation, the appendix could not be clearly identified due to severe inflammation; consequently, cecal resection was performed. He was referred to our department with a chief complaint of general fatigue and loss of appetite and a cystic lesion of approximately 85 mm close to the cecum that had increased over time. CT showed irregular wall thickening, and malignancy could not be ruled out; therefore, laparoscopic ileocecal resection with D3 lymph node dissection was performed. The pathological diagnosis revealed mucinous adenocarcinoma (TXN0M0) arising from the remnant appendiceal tip. The patient is undergoing follow-up without postoperative adjuvant chemotherapy, with no evidence of pseudomyxoma peritonei or cancer recurrence for 32 months postoperatively.ConclusionsIf appendicitis-associated inflammation is sufficiently severe that accurate identification of the appendix is difficult, it may remain on the apical side of the appendix, even if the root of the appendix is ligated and removed. If the appendectomy is terminated incompletely, it is necessary to check for the presence of a residual appendix postoperatively and provide appropriate follow-up.

Using Wearable Devices to Profile Demographic-Specific Recovery After Pediatric Appendectomy

IntroductionCounseling patients and parents about the postoperative recovery expectations for physical activity after pediatric appendectomy varies significantly and is not specific to patients' demographic characteristics. Consumer wearable devices (CWD) can be used to objectively assess patients’ normative postoperative recovery of physical activity. This study aimed to develop demographic-specific normative physical activity recovery trajectories using CWD in pediatric patients undergoing appendectomy. MethodsChildren ages 3-18 y old undergoing laparoscopic appendectomy for acute appendicitis were recruited. Patients wore a Fitbit device for 21 d postoperatively and daily step counts were measured. Patients with postoperative complications were excluded. Segmented regression models were fitted and time-to-plateau was estimated for patients with simple and complicated appendicitis separately for each age group, sex, race/ethnicity, and body mass index category. ResultsAmong 147 eligible patients; 76 (51.7%) were female, 86 (58.5%) were in the younger group, and 79 (53.7%) had complicated appendicitis. Patients 3-11 y old demonstrated a faster trajectory to a physical activity plateau compared to those 12-18 in both simple (postoperative day [POD] 9 versus POD 17) and complicated appendicitis (POD 17 versus POD 21). Males and females had a similar postoperative recovery trajectory in simple and complicated appendicitis. There was no clear pattern differentiating trajectories based on race/ethnicity. Overweight/obese patients demonstrated a slower recovery trajectory in simple appendicitis. ConclusionsThis study demonstrates that factors other than the disease itself, such as age, may affect recovery, suggesting the need for more tailored discharge instructions. CWDs can improve our understanding of recovery and allow for better data-driven counseling perioperatively.

Multi-institutional assessment of the prevalence of neuroendocrine tumors in children undergoing laparoscopic appendectomy for acute appendicitis in the United States.

As non-operative management of acute appendicitis in children has become more common, missed incidental appendiceal pathology can be an unintended consequence. We assessed the prevalence of neuroendocrine tumors in appendectomy specimens from eight US children's hospitals from 2012 to 2021. The prevalence of neuroendocrine tumors (NET) was found to be 1:271, with a median age of 14years and 62% female. Most tumors were small (median 6mm; interquartile range [IQR]: 3-10), and no recurrence was noted during the follow-up period (median 22.5months; IQR: 3-53). The possibility of delayed diagnosis of these tumors should be part of the discussion for non-operative management of pediatric acute appendicitis.

Single-incision laparoscopic appendectomy versus traditional three-hole laparoscopic appendectomy for acute appendicitis in children by senior pediatric surgeons: a multicenter study from China.

The aim of this study was to evaluate the clinical efficacy of single-incision laparoscopy appendectomy (SILA) and traditional three-hole laparoscopy appendectomy (THLA) for the treatment of acute appendicitis in children. The clinical data of children (<14 years old) who underwent laparoscopic appendectomy at Yijishan Hospital of Wannan Medical College, Hubei Provincial Maternal Health Hospital and Qingdao Women and Children's Medical Center from January 2019 to June 2022 were retrospectively analyzed. According to the operation method, the patients were assigned to the SILA group or the THLA group. The clinical data, including the efficacy, and the surgical details, including the complications, of the two surgical methods were compared. The personal information of the children and the time of disease onset were recorded. In this study, the data of 588 patients, including 385 patients in the THLA group and 203 patients in the SILA group were collected. The baseline characteristics between the two groups of patients before surgery were comparable. There was no significant difference in the average operation time between the THLA group and the SILA group (56.31 ± 1.83 min vs. 57.48 ± 1.15 min, P > 0.05). There was also no significant difference in the average length of hospital stay between the THLA group and the SILA group (6.91 ± 0.24 days vs. 7.16 ± 0.36 days, P > 0.05). However, the FLACC scores of the SILA group (3.71 ± 0.78) were significantly lower than those of the THLA group (3.99 ± 0.56) on the second postoperative day, and the difference was significant (P < 0.05). The score of the questionnaire evaluating cosmetic appearance of the postoperative abdomen was significantly higher in the SILA group (15.81 ± 0.36) than in the THLA group (13.10 ± 0.24) (P < 0.05). There was no significant difference in the incidence of postoperative complications between the two groups (P > 0.05). SILA is more advantageous in terms of postoperative FLACC scores and cosmetic appearance in children than THLA. There was no significant difference in the incidence of complications or other aspects between the two surgical methods.

Risk Factors for Conversion from Laparoscopic to Open Appendectomy.

(1) Background: Since its introduction in the 1990s, laparoscopic appendectomy has become established over the years and is today considered the standard therapy for acute appendicitis. In some cases, however, a conversion to the open approach is still necessary. The primary aim of this study was to identify risk factors for the need to convert from the laparoscopic to an open approach during appendectomy for acute appendicitis. (2) Methods: A retrospective analysis of 1220 adult patients who underwent laparoscopic appendectomy for acute appendicitis from 2010 to 2020 at the University Hospital Erlangen was performed. Data, including patient demographics and pre-, intra-, and postoperative findings, were collected and compared between patients with and without conversion. (3) Results: The conversion rate in our cohort was 5.5%. A higher preoperative WBC count and CRP (OR 1.9, p = 0.042, and OR 2.3, p = 0.019, respectively), as well as the presence of intraoperative perforation, necrosis or gangrene, perityphlitic abscess and peritonitis (OR 3.2, p = 0.001; OR 2.3, p = 0.023; OR 2.6, p = 0.006 and OR 2.0, p = 0.025, respectively) were identified as independent risk factors for conversion from the laparoscopic to the open approach. Conversion was again independently associated with higher morbidity (OR 2.2, p = 0.043). (4) Conclusion: The laparoscopic approach is feasible and safe in the majority of patients with acute appendicitis. Only increased inflammatory blood markers could be detected as the preoperative risk factors potentially influencing the choice of surgical approach but only with low specificity and sensitivity. For the decision to convert, intraoperative findings are additionally crucial. However, patients with conversion should receive special attention in the postoperative course, as these have an increased risk of developing complications.

A prospective randomized controlled study comparing patient-reported scar evaluation of single-port versus multiport laparoscopic appendectomy for acute appendicitis.

This study aimed to compare the postoperative outcomes and patient-surveyed scar assessments of single-port laparoscopic appendectomy (SPLA) with the outcomes of multiport laparoscopic appendectomy (MPLA). Between August 2014 and November 2017, the prospective randomized study comprised 98 patients diagnosed with acute appendicitis and indicated for surgery. Fifty-one patients had MPLA and 47 patients received SPLA. The primary endpoint was the total score of Patient Scar Assessment Questionnaire (PSAQ) administered to patients 6 weeks after surgery. SPLA involved a shorter median operative time than MPLA (47.5 minutes vs. 60.0 minutes, p = 0.02). There were no apparent differences in the time before diet tolerance, length of hospital stay, and postoperative complication. SPLA patients had shorter total incision length (2.0 cm vs. 2.5 cm, p < 0.01) and required fewer analgesics on the day of surgery than MPLA patients (p = 0.011). The PSAQ favored the SPLA approach, revealing significant differences in total score (48 vs. 55, p = 0.026), appearance (15 vs. 18, p = 0.002), and consciousness (8 vs. 10, p = 0.005), while satisfaction with appearance and symptoms scale did not (p = 0.162 and p = 0.690, respectively). The postoperative scar evaluated by the patient was better with SPLA than with MPLA, and patient satisfaction with the scar was comparable between the two techniques.

Open versus laparoscopic appendectomy for acute appendicitis in pregnancy: a population-based study.

Laparoscopic appendectomy (LA) is the standard treatment for acute appendicitis (AA) in general population. However, the safety of LA during pregnancy has remained a matter of debate. The purpose of this study was to compare surgical and obstetrical outcomes in pregnant women who underwent LA vs. open appendectomy (OA) for AA. We hypothesized that LA results in improved surgical and obstetric outcomes during pregnancy. Using a nationwide claim-based database in Estonia, a retrospective review of all cases of pregnant women undergoing OA or LA for AA from 2010 to 2020 was performed. Patient characteristics, surgical and obstetrical outcomes were analyzed. Primary outcomes were preterm delivery, fetal loss and perinatal mortality. Secondary outcomes included operative time, hospital length of stay (HLOS) and 30-day postoperative complications. Overall, 102 patients were included of whom 68 (67%) underwent OA and 34 patients (33%) LA, respectively. Patients in LA cohort had a significantly shorter length of pregnancy in terms of gestational weeks when compared to OA cohort (12weeks versus 17weeks, p = 0.002). Most of the patients in their 3rd trimester pregnancy were subjected to OA. Operative time in LA cohort was shorter than in OA cohort (34min. versus 44min., p = 0.038). HLOS in LA cohort was shorter than in OA cohort (2.1days versus 2.9days, p = 0.016). There were no differences between OA and LA cohorts in terms of surgical complications or obstetrical outcomes. Laparoscopic appendectomy for acute appendicitis was associated with a significantly shorter operative time and a shorter hospital length of stay while open and laparoscopic appendectomy cohorts experienced comparable obstetrical outcomes. Our findings support the laparoscopic approach for acute appendicitis in pregnancy.

Clinical Outcomes of Daytime Versus Nighttime Laparoscopic Appendectomy in Children

Aim of the study: To evaluate the clinical outcomes and complication rate of laparoscopic appendectomy in children operated on during the daytime versus nighttime. Methods: A total of 303 children who underwent laparoscopic appendectomy for acute appendicitis between 1 January 2020 and 31 December 2022 were enrolled in this retrospective study. The patients were divided into two study groups. The first group consisted of the patients who underwent laparoscopic appendectomy during the day shift from 07:00-21:00 (n = 171), while the patients in the second group underwent laparoscopic appendectomy during the night shift from 21:00-07:00 (n = 132). The groups were compared for baseline clinical and laboratory data, treatment outcomes, and complications. The Mann-Whitney U test was used to compare continuous variables, while the Chi-square test was used to compare categorical variables. A two-sided Fisher's exact test was used when the frequency of events in a certain cell was low. All p values less than 0.05 were considered significant. Results: The proportion of complicated appendicitis was almost the same in both patient groups (n = 63, 36.8% vs. n = 49, 37.1%, p = 0.960). Out of the total number of patients presenting during the daytime and nighttime, 11 (6.4%) and 10 (7.6%) developed a postoperative complication, respectively (p = 0.697). Additionally, rates of readmission (n = 5 (2.9%) vs. n = 2 (1.5%); p = 0.703), redo-surgery (n = 3 (1.7%) vs. n = 0; p = 0.260), conversion to open surgery (n = 0 vs. n = 1 (0.8%); p = 0.435) and length of hospital stay (n = 3 (IQR 1, 5) vs. n = 3 (IQR 2, 5); p = 0.368) did not differ significantly between daytime and nighttime appendectomies. The duration of the surgery was significantly shorter in patients presenting during the day than in those presenting at night (26 min (IQR 22, 40) vs. 37 min (31, 46); p < 0.001). Conclusions: Different shift times did not affect the treatment outcomes or complication rates for children receiving laparoscopic appendectomy.

Use of Negative Pressure Wound Therapy to Successfully Treat Postoperative Pyoderma Gangrenosum Following Laparoscopic Surgery: A Case Report

Introduction. PG is a rare neutrophilic skin disorder with a variable clinical presentation, and diagnosis is often delayed. PPG typically presents as a necrotic ulcerative lesion with surrounding erythema and is often mistaken for a surgical site infection. Delayed diagnosis can lead to extensive morbidity and a prolonged healing time. Case Report. A 75-year-old male presented to the emergency department 2 weeks following laparoscopic appendectomy for acute appendicitis. He had fever and a suspected surgical site infection. Antibiotic treatment was initiated, and debridement was performed. Eventually, the diagnosis of PPG was made. Immunosuppressive therapy combined with NPWT was initiated. Complete wound healing was achieved 2 months after admission. Conclusions. Surgeons should have a high index of suspicion of underlying skin disorders when presumed postoperative wound infections do not respond to aggressive antibiotic and surgical treatment. Early multidisciplinary consultation should be considered. In the case of PPG, the authors of the present report advise early initiation of systemic immunosuppressive therapy combined with atraumatic wound care. NPWT should be considered as appropriate. Surgical debridement may be indicated in the setting of extensive necrosis or uncontrollable superinfection.

Impact of the COVID-19 pandemic on the outcomes of laparoscopic appendectomy for acute appendicitis.

This retrospective study aimed to evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on the time interval from symptom onset to surgery and on the operative outcomes of laparoscopic appendectomy for patients with acute appendicitis. Between October 2018 and July 2021, laparoscopic appendectomy was performed in 502 patients with acute appendicitis admitted to Hallym University Chuncheon Sacred Heart Hospital in Chuncheon, Korea. We compared demographic data, serum levels of inflammatory markers, time to event of appendicitis, and operative outcomes between the pre-COVID-19 and post-COVID-19 pandemic groups. Laparoscopic appendectomy was performed in 271 patients in the pre-COVID-19 group and in 231 patients in the post-COVID-19 group. There were no differences in baseline characteristics, serum inflammatory marker levels, or the proportions of complicated appendicitis between the groups (25.1%, pre-COVID-19 vs. 31.6%, post-COVID-19; P = 0.106). The time intervals between symptom onset and hospital arrival (24.42 hours vs. 23.59 hours, P = 0.743) and between hospital arrival and the start of surgery (10.12 hours vs. 9.04 hours, P = 0.246) did not increase post-COVID-19. The overall 30-day postoperative complication rate did not differ significantly between the groups (9.6% vs. 10.8%, P = 0.650), and the severity of 30-day postoperative complications was also similar in both groups (P = 0.447). This study demonstrates that hospitalization and surgeries were not delayed in patients with acute appendicitis and that the operative outcomes of laparoscopic appendectomy did not worsen despite the COVID-19 pandemic.

Synchronous gallbladder perforation and appendicitis in a pediatric patient

Acute appendicitis and acute cholecystitis are among the most common diagnoses operated by general surgeons. However, synchronous appendicitis and cholecystitis have rarely been reported and most cases have been described as acalculous cholecystitis and appendicitis in early stages that are not absolutely synchronous. We report a case of a fourteen-year-old male patient who presented acute acalculous cholecystitis with gallbladder perforation at the time of a laparoscopic appendectomy for acute appendicitis. Acute acalculous cholecystitis is an acute necroinflammation of the gallbladder in the absence of gallstones. In the pathophysiology the main factor is gallbladder wall ischemia with microcirculation failure and biliary stasis. There is discussion about the coexistence of acute appendicitis with acute cholecystitis with a presumed pathophysiological relationship; however, this is not well described. In this case it was found an acute acalculous cholecystitis in advanced stages with gallbladder perforation and a synchronous presentation of acute appendicitis. The synchronous presentation of acute appendicitis and cholecystitis with its complications, such as spontaneous perforation, is rare, but should be considered as a cause of acute abdomen with a pathophysiology still unknown.

Patient Outcomes in Laparoscopic Appendectomy With Acute Surgical Care Model Compared to Traditional Call

IntroductionShift-based models for acute surgical care (ACS), where surgical emergencies are treated by a dedicated team of surgeons working shifts, without a concurrent elective practice, are becoming more common nationwide. We compared the outcomes for appendectomy, one of the most common emergency surgical procedures, between the traditional (TRAD) call and ACS model at the same institution during the same time frame. MethodsA retrospective review of patients who underwent laparoscopic appendectomy for acute appendicitis during 2017-2018. ACS and TRAD-patient demographics, clinical presentation, operative details, and outcomes were compared using independent sample t-tests, Wilcoxon rank-sum tests and Fisher's exact or χ2 tests. Multiple exploratory regression models were constructed to examine the effects of confounding variables. ResultsDemographics, clinical presentation, and complication rates were similar between groups except for a longer duration of symptoms prior to arrival in the TRAD group (Δ = 0.5 d, P = 0.006). Time from admission to operating room (Δ = −1.85 h, P = 0.003), length of hospital stay (Δ = −2.0 d, P < 0.001), and total cost (Δ = $ −2477.02, P < 0.001) were significantly lower in the ACS group compared to the TRAD group. Furthermore, perforation rates were lower in ACS (8.3% versus 28.6%, P = 0.003). Differences for the outcomes remained significant even after controlling for duration of symptoms prior to arrival (P < 0.05). ConclusionsAcute appendicitis managed using the ACS shift-based model seems to be associated with reduced time to operation, hospital stay, and overall cost, with equivalent success rates, compared to TRAD.

TH6.2 Day Case Laparoscopic Appendicectomy for Acute Appendicitis In Adults: A Retrospective Case Series Study

Abstract Aims Laparoscopic appendectomy (LA) is nowadays considered the standard of care as it is associated with shorter hospital stay and fewer complications. The purpose of this study was to assess the safety of same-day discharge after laparoscopic appendectomy for acute appendicitis at a tertiary Care Center. Methods A retrospective chart review was performed for patients &amp;gt;18 years old who underwent LA for acute appendicitis in 2021. Patients were categorized into 2 groups: discharge in &amp;lt;24h or admission for &amp;gt;24-h. Demographic data, postoperative length of stay, histology report, complications and readmission rates were abstracted from patient medical records. Results A total of 303 laparoscopic appendicectomies were included. Of these, 71 patients had Length Of Stay (LOS) less than 24 hours. Pathology, comorbidities, and readmission were recorded. Average LOS for all patients was 7 hours with a minimum stay of 4 hours and a maximum stay of 23 hours. For patients discharged in less than 24 hours, there was no readmission and 58 (19.1%) of these patients had simple appendicitis on pathology. A total of 26 patients (8.58%) were discharged in less than 7 hours (from the recovery room). There was no significant difference in complications or readmission between patients discharged in less than 24 hours and those who stayed longer. Conclusion Day case LA is a safe and effective practice for treating selected patients with non-perforated appendicitis, as it decreases the length of stay and hospital charges.

Comparison of Single-Dermatome Laparoscopic Appendectomy With Standard Laparoscopic Appendectomy in Terms of Postoperative Pain and Patient Satisfaction: A Randomized Controlled Trial.

Laparoscopic appendectomy (LA), used since 1980, is a common surgical technique for acute appendicitis (AA) treatment. Laparoscopic surgical techniques can achieve higher patient satisfaction than conventional open surgery techniques. However, many patients complain of severe pain after laparoscopic abdominal surgeries. In this study, we compared single-dermatome laparoscopic appendectomy (SDLA), wherein all trocars were placed at the same dermatome field, with standard laparoscopic appendectomy (SLA), wherein trocars were placed at multiple dermatome sites, in terms of postoperative pain and patient satisfaction. The study was designed as a double-blind randomized controlled trial. Patients who underwent LA for AA between May 2019 and December 2019 were included in the study and randomized into 2 groups, wherein patients were included sequentially. The first group was operated with SLA surgery, whereas the second group was operated with SDLA surgery. All patients were assessed in terms of visual analog scale (VAS) scores, hemodynamic parameters, and patient satisfaction at postoperative 1, 2, 4, 6, 12, and 24 hours. In the SLA technique, VAS values at postoperative 1, 2, and 4 hours were significantly higher than in the SDLA ( P =0.009; P <0.05). No significant difference was observed between the surgical techniques in terms of VAS levels at postoperative 6, 12, and 24 hours ( P >0.05). In the SDLA group, patient satisfaction was significantly higher than in the SLA group ( P =0.024; P <0.05). In our study, SDLA caused less pain in AA cases during postoperative period than SLA. Further, the SDLA method achieved higher patient satisfaction during the postoperative period than the SLA method.

Meta-analysis of the clinical efficacy of laparoscopic appendectomy in the treatment of acute appendicitis

BackgroundThis paper compares the postoperative recovery of patients with acute appendicitis (AA) after laparoscopic appendectomy (LA) and open appendectomy (OA), aiming to determine the optimal diagnosis and treatment plan for appendectomy.MethodsRelated literature was retrieved from PubMed, Web of Science, Embase, CNKI and Wanfang databases. Articles on LA and OA for AA published between 2010 and 2021 were selected to extract data. Besides, Stata16.0 was used for meta-analysis.ResultsA total of 777 articles were retrieved, and 16 of them were finally selected. Totally, 1251 patients underwent LA, while 898 patients received OA. According to the results of meta-analysis, LA was associated with lower incidence of adverse reactions [OR = 0.257, 95% CI (0.162, 0.408), P < 0.001], shorter operation time (SMD = − 1.802, 95% CI − 2.435, − 1.169; P < 0.001) and hospitalization (SMD = − 1.184, 95% CI − 1.512, − 0.856; P < 0.001). In addition, compared with the OA group, LA was found with less intraoperative blood loss (SMD = − 3.650, 95% CI − 5.088, − 2.212; P < 0.001) and shorter recovery time of gastrointestinal function (SMD = − 3.010, 95% CI − 3.816, − 2.203; P < 0.001). Aside from all these, the counts of leukocyte (SMD = − 0.432, 95% CI: − 0.775, − 0.089; P = 0.013), neutrophil (SMD = − 1.346, 95% CI − 2.560, − 0.133; P = 0.030), and C-reactive protein (SMD = − 2.391, 95% CI − 3.901, − 0.882; P = 0.002) all decreased in a significant manner after LA.ConclusionCompared with OA, LA boasts the advantages of less adverse reactions, shorter operation time and hospitalization, fewer complications, and lower inflammatory response, evidencing its safety and feasibility of applying in the treatment of AA.

Hybrid Appendectomy in Pediatric Appendicitis: A Comparative Analysis of Single-Port and Multiport Laparoscopic Appendectomy.

Background: Hybrid appendectomy (HA) has the technical advantages of the excellent visual field provided by laparoscopic surgery and is fast and easy similar to open surgery. We aimed to compare the safety and effectiveness of HA with single- and multiport laparoscopic appendectomy (SPLA and MPLA) in pediatric patients with acute appendicitis. Materials and Methods: This retrospective study compared the short-term operative outcomes between HA, SPLA, and MPLA groups. From January, 2010 to December, 2019, 239 patients aged <12 years who underwent laparoscopic appendectomy for acute appendicitis were included. The primary outcome was the 30-day postoperative complication rate, stratified according to the modified Clavien-Dindo classification. Results: In 239 patients, HA was more frequently performed in patients with a low body mass index (17.42 versus 18.97 kg/m2 in the SPLA group versus 18.44 kg/m2 in the MPLA group, P = .029) and tended to be more frequently adopted in uncomplicated appendicitis. In uncomplicated appendicitis, the HA group had a significantly shorter operation time than the MPLA group (31.77 versus 40.09 min, P < .001), but had a comparable operation duration with the SPLA group. The rate of 30-day postoperative complications was not significantly different between the groups (HA 7.6% versus SPLA 7.8% versus MPLA 5.4%, P = .841). The postoperative time to resume water intake was significantly longer in the SPLA group than in the HA and MPLA groups (P = .008). Conclusions: HA showed a short operation time, fast functional recovery, and acceptable postoperative complication rate in patients with uncomplicated appendicitis and can be safely and effectively performed in these patients.

Pain management after laparoscopic appendectomy: Comparative effectiveness of innovative pre-emptive analgesia using liposomal bupivacaine

BackgroundLaparoscopic appendectomy is standard of care for appendicitis in the US. Pain control that limits opioids is an important area of research given the opioid epidemic. This study examined post-appendectomy inpatient opioid use and pain scores following intraoperative use of liposomal bupivacaine (LB) versus non-liposomal bupivacaine. MethodsThis was a retrospective cohort study of 155 adults who underwent laparoscopic appendectomy for acute appendicitis. Patients were divided into four cohorts based on the analgesia administered: (i) bupivacaine hydrochloride (BH)± epinephrine; (ii) undiluted LB; (iii) LB diluted with normal saline; and (iv) LB diluted with BH. ResultsBaseline demographic/clinical attributes, intra-operative findings, and post-operative pain scores were equivalent across cohorts. Post-operative pre-discharge opioid use was higher in the BH vs. LB cohorts (mean 60.4 vs. 46.0, 35.5, and 30.4 morphine milligram equivalents, respectively; p < 0.001). ConclusionsPre-emptive analgesia with LB during laparoscopic appendectomy can reduce inpatient opioid use without significantly increasing post-operative pain scores.
