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

Therapeutic effectiveness and influencing factors of laparoscopic appendectomy with mesoappendix dissection in the treatment of acute appendicitis

BACKGROUND

Acute appendicitis (AP) is a frequently encountered surgical emergency, and appendectomy is conventionally regarded as the predominant treatment modality. Nevertheless, the therapeutic efficacy of this surgical approach remains to be improved. Thus, the exploration and implementation of surgical refinements are necessary.

AIM

To elucidate the therapeutic effectiveness and influencing factors of laparoscopic appendectomy (LA) with mesoappendix dissection in the treatment of AP.

METHODS

First, 150 patients with AP who visited Shangrao Municipal Hospital between January 2022 and June 2024 were enrolled in this study. Among them, 72 patients were assigned to the control group to receive conventional LA, whereas 78 cases were included in the observation group for LA with mesoappendix dissection. Subsequently, indicators such as therapeutic effectiveness, surgical indices (operation time, intraoperative blood loss, and hospital stay), postoperative recovery indices (time to ambulation, gastrointestinal function recovery time, and time to food intake), incidence of adverse events (postoperative bleeding, pelvic infection, puncture site infection, and ileus), and serum inflammatory factors [tumor necrosis factor (TNF)-α, interleukin (IL)-6, and C-reactive protein (CRP)] were collected and comparatively analyzed, and the influencing factors of therapeutic effectiveness in patients with AP were analyzed.

RESULTS

Compared with the control group, the observation group had higher clinical therapeutic effectiveness, less operation time, intraoperative blood loss, and hospital stay; shorter time to ambulation, gastrointestinal function recovery, and food intake; and a lower total incidence of adverse events, and this difference is statistically significant. In addition, the expression levels of various serum inflammatory factors in the observation group were significantly reduced postoperatively, which were markedly lower than those in the control group. Moreover, sex, age, body mass index, time from acute onset to admission, family medical history, preoperative TNF-α, preoperative IL-6, preoperative CRP, and treatment modality were identified to be not independent factors affecting the therapeutic effectiveness of LA with mesoappendix dissection in patients with AP.

CONCLUSION

Overall, LA with mesoappendix dissection has a remarkable curative effect in treating patients with AP, which is worthy of clinical promotion.

Single Incision Laparoscopic Surgery for Malone Antegrade Continent Enema: Optimizing Outcomes in Pediatric Bowel Management

BACKGROUND

Malone antegrade continence enemas (MACE) are increasingly being used to manage severe constipation and fecal incontinence in children. Despite advances in minimally invasive pediatric colorectal surgery, single-incision laparoscopic surgery (SILS) for MACE creation remains relatively unexplored. This study, featuring the largest cohort to date, evaluates the feasibility, safety, and clinical outcomes of SILS MACE creation in children.

METHODS

A single-institution, retrospective review of pediatric patients who underwent SILS MACE creation for severe constipation and/or fecal incontinence between March 2022 and July 2024. Patient demographics, operative data, postoperative complications, and stooling patterns were assessed. Quantitative variables were analyzed using descriptive statistical methods.

RESULTS

Eighteen patients (10 males, 56 %) underwent SILS MACE creation at a mean age of 10 years (range 4-18) and a median BMI of 17.6 kg/m2 (IQR 16.8-19.6). Preoperative diagnoses included anorectal malformation (n = 9, 50 %), functional constipation (n = 4, 22 %), neurogenic bowel (n = 3, 17 %), and Hirschsprung Disease (n = 2, 11 %). Median operative time was 51 min (IQR 38-67), Postoperative complications included channel prolapse (n = 3, 17 %) and wound infection (n = 2, 11 %). Two patients (11 %) required interventional radiology owing to Mini-ACE® button dislodgment and one patient (5 %) required operative revision for skin-level stenosis. At a median follow-up of 13 months (IQR 7-18), 16 patients (89 %) were clean for stool with successful management through antegrade flushes.

CONCLUSION

SILS MACE creation is a safe, feasible, and effective minimally invasive approach for managing severe constipation and fecal incontinence in children. The technique demonstrates potential advantages in cosmetic results and comparable surgical outcomes, offering a viable alternative to the traditional multiport laparoscopic approach.

Factors prolonging the operative time for transumbilical laparoscopic-assisted appendectomy in pediatric patients: a retrospective single-center study

PURPOSE

Transumbilical laparoscopic-assisted appendectomy (TULAA) is one of the first endoscopic surgeries performed by trainee pediatric surgeons. While the operative time is generally shorter than for conventional laparoscopic appendectomy, the indications for this procedure are unclear and many unknown factors can prolong the operative time. We conducted this study to identify the factors that may prolong the operative time for TULAA.

METHODS

This retrospective, single-center study was conducted between 2015 and 2023. We performed multivariate analysis to identify the factors associated with prolonged operative time by analyzing TULAA procedures performed by trainees.

RESULTS

The study included 243 patients. The median operative time was 84 min (interquartile range, 69-114 min). Multivariate analysis revealed that an increased body mass index, elevated C-reactive protein level, a history of conservative treatment for acute appendicitis, and appendix perforation, for the patient; < 6 years' experience since graduation for the operating surgeon; and lack of board certification as a supervisor from the Japanese Society of Pediatric Surgeons for the attending surgeon were independent risk factors for prolonging the operative time.

CONCLUSION

Having an attending surgeon with board certification as a supervisor by the Japanese Society of Pediatric Surgeons contributes to reducing the operative time required for TULAA.

Application of transumbilical single-incision laparoscopy in the treatment of complicated appendicitis in overweight/obese adolescents

OBJECTIVE

To investigate the clinical efficacy of transumbilical single-incision laparoscopic surgery in the treatment of complicated appendicitis in overweight/obese adolescents.

METHODS

A retrospective analysis was conducted on the clinical data of 226 adolescent patients with complicated appendicitis who were admitted to our hospital from January 2014 to June 2022. Among them, 102 cases underwent transumbilical single-incision laparoscopic appendectomy as the observation group, and another 124 cases underwent conventional three-port laparoscopic appendectomy as the control group. The surgical time, intraoperative blood loss, duration of incisional pain, postoperative flatus time, length of hospital stay, surgical site infection (SSI), satisfaction with cosmetic result, and occurrence of postoperative complications were compared between the two groups.

RESULTS

Both groups completed the surgery smoothly, and there were no statistically significant differences in gender, age, BMI, duration of illness, white blood cell count, and preoperative CRP value between the two groups (P > 0.05). There were no statistically significant differences in surgical time and intraoperative blood loss between the two groups (P > 0.05). However, the observation group had shorter hospital stays, shorter duration of incisional pain, shorter postoperative time to flatus, and lower overall postoperative complication rates compared to the control group, with statistically significant differences (P < 0.05). The observation group had higher satisfaction with cosmetic result compared to the control group, with statistically significant differences (P < 0.05). Both groups were followed up for one year postoperatively, and there were no occurrences of residual appendicitis or severe adhesive intestinal obstruction.

CONCLUSION

When proficiently mastered, the application of transumbilical single-incision laparoscopy in the treatment of complicated appendicitis in overweight/obese adolescents offers advantages such as minimal trauma, rapid recovery, fewer complications, and improved aesthetic outcomes.

A trans-umbilical single-site plus one robotic-assisted surgery for choledochal cyst resection in children

Objective

The purpose of this study is to compare the intraoperative and postoperative outcomes of a trans-umbilical single-site plus one robot-assisted surgery and a trans-umbilical single-site laparoscopic surgery in the treatment of choledochal cysts.

Methods

We retrospectively analyzed clinical data from 49 children diagnosed with choledochal cysts who were admitted to our hospital between June 2020 and December 2023. Among these patients, 24 underwent a trans-umbilical single-site plus one Da Vinci robot-assisted surgery (the robot group) and 25 underwent a trans-umbilical single-site laparoscopic-assisted surgery (the laparoscopic group). We compared differences in intraoperative and postoperative outcomes between the two groups.

Results

There was no significant difference between the two groups of patients in terms of gender, age, weight, clinical symptoms, maximum cyst diameter, type, postoperative complications, and facial expression, leg movement, activity, crying, and comfortability (FLACC) scoring (p > 0.05). Compared with the patients in the laparoscopic group, those in the robot group had less intraoperative bleeding [10 (8-12) vs. 15 (11.5-18) ml, p < 0.001] and required less postoperative drainage tube indwelling time [5 (4-6) vs. 7 (5.5-8) day, p < 0.001], less postoperative fasting time [4 (3-4) vs. 6 (5-7) days, p < 0.001], and less postoperative hospitalization time [6 (6-7) vs. 8 (6-10) days, p < 0.001], but they required more operative time [385.5 (317.0-413.3) vs. 346.0 (287.0-376.5) min, p = 0.050] and consumed more hospitalization expenses (79,323 ± 3,124 vs. 31,121 ± 2,918 yuan, p < 0.001).

Conclusion

The results of this study showed a shorter hospitalization time, quicker postoperative recovery, and less tissue damage but a higher cost and a longer operation time in patients who chose robotic surgery rather than laparoscopic surgery. With the continuous expansion of the scale of installed robot-assisted surgical systems and the gradual accumulation of the technical experience of surgeons, robot-assisted surgery may slowly surpass, and shows a trend to replace, laparoscopy because of its advantages.

Laparoscopic appendectomy with single port vs conventional access: systematic review and meta-analysis of randomized clinical trials

BACKGROUND

Conventional three-access laparoscopic appendectomy (CLA) is currently the gold standard treatment, however, Single-Port Laparoscopic Appendectomy (SILA) has been proposed as an alternative. The aim of this systematic review/meta-analysis was to evaluate safety and efficacy of SILA compared with conventional approach.

METHODS

Per PRISMA guidelines, we systematically reviewed randomised controlled trials (RCTs) comparing CLA vs SILA for acute appendicitis. The randomised Mantel-Haenszel method was used for the meta-analysis. Statistical data analysis was performed with the Review Manager software and the risk of bias was assessed with the Cochrane "Risk of Bias" assessment tool.

RESULTS

Twenty-one studies (RCTs) were selected (2646 patients). The operative time was significantly longer in the SILA group (MD = 7,32), confirmed in both paediatric (MD = 9,80), (Q = 1,47) and adult subgroups (MD = 5,92), (Q = 55,85). Overall postoperative morbidity was higher in patients who underwent SILA, but the result was not statistically significant. In SILA group were assessed shorter hospital stays, fewer wound infections and higher conversion rate, but the results were not statistically significant. Meta-analysis was not performed about cosmetics of skin scars and postoperative pain because different scales were used in each study.

CONCLUSIONS

This analysis show that SILA, although associated with fewer postoperative wound infection, has a significantly longer operative time. Furthermore, the risk of postoperative general complications is still present. Further studies will be required to analyse outcomes related to postoperative pain and the cosmetics of the surgical scar.
