Single-Incision Pediatric Laparoscopic Surgery: Surgical Outcomes, Feasibility Indication, and the Systematic Review

Background: Single-incision laparoscopic surgery (SILs) has reported the evidence in basic and advanced pediatric laparoscopy. The objective was to review the feasibility and outcomes between basic and advanced procedures of the conventional laparoscopic surgery (CLs) and the SILs at our institute, and to compare the results with the published studies in a systematic review and meta-analysis. Patients and Methods: A retrospective study was conducted from January 2017 to March 2020. Demographic data, operations, conversion rate, and complications were collected and analyzed. The MEDLINE and PubMed were searched in relation to the pediatric SILs and the pediatric CLs in the published series from 1985 to 2021. We combined our retrospective study with a systematic review for meta-analysis. Results: Two hundred twenty-seven patients underwent pediatric laparoscopic surgery during the study period. The procedures included 199 (87.7%) for basic laparoscopy (appendectomy, cholecystectomy, testicular vessel ligation, closure of indirect inguinal hernia, and hydrocele) and 28 (13.3%) for advanced laparoscopy (Meckel diverticulectomy, pull-through operation for Hirschsprung's disease, choledochal cyst excision, and Nissen fundoplication). There was no statistical significance in operative time, length of stay (LOS), conversion rate, recurrence, and complication. The systematic review demonstrated 19 studies and, combined with our present study, produced 2865 patients for analysis. The meta-analysis reported increased LOS in the SILs group in cholecystectomy (mean difference [MD] 0.23 day, 95% confidence intervals [CI] 0.02-0.43 day, P = .03 and I² = 0%) and choledochal cyst excision (MD 0.18 day, 95% CI 0.02-0.33 day, P = .03 and I² = 0%). There was no statistical difference in operative time, LOS, conversion, and complication in other procedures. Conclusion: The SILs is a feasible indication and safe for surgical pediatric laparoscopy including basic to advanced procedure laparoscopy. It is demonstrated that there were no statistical differences in the operative time, LOS, and the complication. However, LOS in some procedures seems to be different due to the complexity and guideline.

Stepwise approach to laparoscopic appendicectomy in children

Traditionally, three ports are used in laparoscopic appendicectomy. However to reduce surgical incision and cost, it is feasible to remove the appendix using fewer ports. In this study, we compared the efficacy of stepwise and standard approach in laparoscopic appendicectomies in children. Between August 2008 and September 2010, 378 children with appendicitis were allotted to either the stepwise or standard laparoscopy group depending on the operating surgeon's preference. In the former group, an operating telescope was inserted first. The number of ports used was based on the pathology (stepwise approach). In the latter group, three ports were inserted in all patients (standard approach). The two groups were similar. In the stepwise group, we performed 95 single port (utilising a scope with an instrument channel), 37 two ports and 13 three ports appendicectomies. In the stepwise group, operating time was shorter (not yet statistically significant) and it reduced the port numbers by more than 50 %. The stepwise approach provides an evidence-based management of appendicitis with comparable outcomes. This procedure further reduces incision trauma, operating times and the cost of operation. However, the reduction of post-operative analgesic requirement needs further study.

Transumbilical laparoscopically assisted appendectomy in children: the results of a single-port, single-channel procedure

BACKGROUND

Even for pediatric patients, the use of laparoscopic appendectomy has been widely accepted, and three trocars usually are necessary to perform a laparoscopic appendectomy. However, single-port appendectomy for children represents an attractive alternative. To reduce the number of incisions and trocars, the authors have adopted a transumbilical laparoscopically assisted single-port appendectomy (TULAA) approach. This study aimed to evaluate the results of their single-channel, single-port appendectomy.

METHODS

A retrospective study of TULAA was performed during 12 years with 500 children ages 2-16 years (median, 10.2 years). The TULAA approach is a single-channel surgery using a 12 mm conventional single-port. The vertical incision through the umbilicus is used for laparoscopic access. Two laparoscopic instruments, a 5 mm telescope and a 5 mm grasper, are inserted simultaneously into the single-channel. The grasper holds the base of the appendix, and the appendix is exteriorized through the umbilical incision. Thereafter, a conventional appendectomy is performed extracorporeally.

RESULTS

The TULAA procedure was successful for 416 patients (83.2%). These successful TULAA procedures required a mean surgery time of 44.5 min. The pathologic diagnosis of the appendix was acute for 59 patients, phlegmonous for 203 patients, gangrenous for 152 patients, and not detected for two patients. Complications occurred for 47 of these patients (11.3%). Most of the complications were associated with severe intraabdominal inflammation. Two patients needed reoperation under general anesthesia. Conversion to multitrocar surgery or open appendectomy was performed for 84 of the patients (16.8%).

CONCLUSIONS

The TULAA procedure is a preferable operation for acute appendicitis in children because it is simple and provides good cosmetic results.

Single-incision laparoscopic surgery in children: initial single-center experience

BACKGROUND

In continued efforts to further improve the advantages of minimally invasive surgery to patients, surgeons have developed single-incision laparoscopic techniques. We report our initial experience in children with a variety of single-site procedures.

METHOD

A retrospective chart review was performed on patients who underwent a single-site procedure from April 2009 to April 2010.

RESULTS

There were 142 consecutive procedures: 24 cholecystectomies, 103 appendectomies for nonperforated appendicitis, 2 splenectomies, 1 combined splenectomy/cholecystectomy, 8 ileocecectomies, 2 Meckel diverticulectomies, 1 small bowel duplication resection, and 1 jejunal stricture resection. There were 12 conversions to conventional laparoscopy: 10 during appendectomy and 2 during cholecystectomy. Mean operative time was 34 minutes for appendectomy, 73 minutes for cholecystectomy, 90 minutes for splenectomy, 116 minutes for combined splenectomy/cholecystectomy, 86 minutes for ileocecectomy, and 43 minutes for the small bowel procedures. The only complications were umbilical surgical site infections after appendectomy in 6 patients.

CONCLUSION

This institution's preliminary experience suggests that single-incision laparoscopic surgery in children has at least comparable outcomes to conventional laparoscopic surgery. However, prospective data are needed to prove that single-incision laparoscopic surgery is superior to conventional laparoscopy.

A review of single site minimally invasive surgery in infants and children

Videoscopic surgery has become the standard approach for most thoracic, abdominal, and pelvic procedures in adults and children. These procedures have widely recognized benefits including decreased postoperative pain, improved cosmesis, and decreased convalescence. In a recent attempt to further improve the cosmetic result of these operations, surgeons have begun to employ a single incision through which all the operating instruments are placed. This article seeks to review the current and future application of innovative minimally invasive surgery to pediatric surgery.
