Comparison between liquid skin adhesive and wound closure strip for skin closure after subcuticular suturing in single-port laparoscopic appendectomy: a single-center retrospective study in Korea.

This study was performed to evaluate the safety and feasibility of skin adhesives and to compare postoperative and cosmetic outcomes after wound closure in single-port laparoscopic appendectomy (SPLA) between skin adhesives and steri-strips. This was a single-center retrospective study. We included 22 and 47 patients in whom skin adhesive and steri-strips were used respectively, for skin closure after subcuticular suturing in SPLA between August 2014 and 2020. The patient scar assessment questionnaire (PSAQ) was completed postoperatively to assess postoperative cosmetic outcomes. On the postoperative day, patients in whom skin adhesive was used had significantly lower numeric rating scores than in whom steri-strips were used (2.8 ± 0.8 vs. 3.9 ± 0.8, p < 0.001). The frequency of analgesic administration within 24 hours and between 24 and 48 hours after surgery was significantly lower in the skin adhesive group compared to the wound closure strip group (1.4 ± 0.8 vs. 2.7 ± 1.2, p = 0.013 and 0.2 ± 0.4 vs. 0.7 ± 0.9, p = 0.002, respectively). In the PSAQ, "satisfaction with appearance" and "satisfaction with symptoms" subitem scores were significantly lower in patients in whom skin adhesive was used (11.3 ± 3.0 vs. 15.1 ± 4.5, p = 0.006 and 6.5 ± 1.8 vs. 9.5 ± 3.3, p = 0.003), whereas, "appearance" and "consciousness" subitems revealed no statistically significant differences between the groups. Liquid skin adhesive closures seem to be safe and feasible and cause less postoperative pain, resulting in greater patient satisfaction with postoperative scars than wound closure strip closure after subcuticular suturing in SPLA.

Single-port laparoscopic appendectomy using new surgical procedure versus conventional three-port laparoscopic appendectomy.

The aim of this study was to compare the clinic outcomes between new single-port laparoscopic appendectomy (NSLA) and conventional three-port laparoscopic appendectomy (CTLA) for patients with acute appendicitis. Patients who were diagnosed with acute appendicitis and underwent appendectomy were retrospectively collected from a single clinical center from September 2021 to June 2023. Baseline characteristics, surgical information, and postoperative information were compared between the NSLA group and the CTLA group. Univariate and multivariate logistic regression analyses were used to find out the predictors of overall complications. A total of 296 patients were enrolled from a single clinical medical center. There were 146 (49.3%) males and 150 (50.7%) females. There were 54 (18.2%) patients in the NSLA group and 242 (81.8%) patients in the CTLA group. After data analysis, we found the patients in the NSLA group had a shorter postoperative hospital stay (P < 0.01) than the CTLA group. The other outcomes including intraoperative blood loss (P = 0.167), operation time (P = 0.282), nature of the appendix (P = 0.971), and overall complications (P = 0.543) were not statistically different. After univariate and multivariate logistic regression analysis, we found that age (P = 0.018, OR = 1.039, 95% CI = 1.007-1.072), neutrophil percentage (P = 0.018, OR = 1.070, 95% CI = 1.011-1.132), and fever (P = 0.019, OR = 6.112, 95% CI = 1.340-27.886) were the predictors of overall complications. However, the surgical procedure (NSLA versus CTLA) was not a predictor of overall complications (P = 0.376, OR = 1.964, 95% CI = 0.440-8.768). Compared with CTLA, there was no significant increase in postoperative overall complications with NSLA, making it a safe and feasible new surgical procedure. More studies are needed to evaluate the long-term results.

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.

Single-port laparoscopic appendectomy for perforated appendicitis using ArtiSential® wristed articulated instrument.

Single-port laparoscopic appendectomy (SPLA) was firstly introduced in 1998 and has been suggested potential advantages including better cosmetic outcome, less post-operative pain and avoidance of possible haemorrhagic complications from injuring epigastric vessels. However, single-port laparoscopic approach using conventional straight instruments may lead to internal and external conflicts and ergonomic discomfort, and new laparoscopic articulating instruments were developed to overcome these limitations of straight instruments. The ArtiSential® (LIVSMED Inc., Republic of Korea) is an 8-mm diameter pistol-handle instrument that has complete articulating function like human wrist and intuitive controllability. We present a technical report of SPLA for perforated appendicitis using ArtiSential® wristed articulated instrument. A 78-year-old female with a body mass index of 23.5 was referred to our emergency room with right lower quadrant abdominal pain. Abdominal computed tomography scan showed a distended tubular structure in the right lower quadrant (1.2 cm in diameter) with periappendiceal fluid collection. The patient's clinical presentation was highly indicative of perforated acute appendicitis. We performed SPLA with ArtiSential® grasper with the left hand, and this instrument helped us to allow greater manoeuvrability and dexterity with double triangulation technique. The total operation time was 40 min, and the patient was discharged without complications on the 1st day after surgery.

Single-port laparoscopic appendectomy using a needle-type grasping forceps compared with conventional three-port laparoscopic appendectomy for patients with acute uncomplicated appendicitis: a single-center retrospective study.

ObjectiveTo compare the clinical outcomes between single-port laparoscopic appendectomy using a needle-type grasping forceps (SLAN) and conventional three-port laparoscopic appendectomy (CLA) for patients with uncomplicated appendicitis.MethodsWe retrospectively collected clinical data of patients with uncomplicated appendicitis who underwent SLAN or CLA from May 2019 to May 2021 in our center. The patients’ baseline characteristics, perioperative outcomes, and follow-up data were compared between the two groups. Additionally, baseline characteristics were compared with postoperative outcomes in the SLAN group.ResultsNinety-six patients were enrolled (SLAN group, n = 32; CLA group, n = 64). The SLAN group had a shorter hospital stay, lower 24-hour postoperative visual analogue scale scores, shorter postoperative fasting time, lower frequency of antibiotic administration, and longer operative time than the CLA group. In the SLAN group, younger patients had a longer appendix and male patients had a thicker appendix; additionally, patients with an appendiceal diameter of 0.6 to 1.0 cm had a longer postoperative hospital stay and higher frequency of antibiotic administration.ConclusionsCompared with CLA, SLAN may be less invasive, provide faster postoperative recovery, and result in better cosmesis for patients with uncomplicated appendicitis. Further research should be performed to evaluate the long-term outcomes.

Clinical Analysis of the Efficacy of Single-port Laparoscopic Appendectomy and Three-port Laparoscopic Appendectomy

Inappropriate manipulation and drainage exacerbate post-operative pain and prolong the hospital stay after laparoscopic appendectomy for pediatric complicated appendicitis

BackgroundThis study examined whether drain placement or not is associated with the postoperative outcomes of pediatric patients following trans-umbilical single-port laparoscopic appendectomy (TUSPLA) for complicated appendicitis.Methods The medical records of pediatric patients undergoing TUSPLA for acute complicated appendicitis from January 2012 to September 2018 in Kaohsiung Chang Gung Memorial Hospital were reviewed retrospectively. They were classified according to whether they received passive drainage with a Penrose drain (Penrose group) (19), active drainage with a Jackson-Pratt drain with a vacuum bulb (JP group) (16), or no drain (non-drain group) (86). The postoperative outcomes of the three groups were compared.ResultsPostoperative visual analog scale pain score was significantly higher in the non-drain group than in either the JP group or Penrose group. Patients in the Penrose group had a significantly longer postoperative hospital stay than those in the non-drain group and a higher rate of intra-abdominal abscess, while patients in the JP group had a significantly shorter postoperative hospital stay; moreover, no patient in JP group developed a postoperative intra-abdominal abscess.ConclusionsCompared to passive drainage with a Penrose drain or no drain, active drainage with a JP drain shorter the postoperative hospital stay and decreased the risk of postoperative intra-abdominal abscess.

Single-Port Laparoscopic Appendectomy Performing by Emergency Operation: An Intervention Study in Vietnam

Background: Appendectomy is one of the most commonly performed surgical procedures of the abdominal area. One of the recent innovations is single-port laparoscopic surgery (SPLS), which can insert multiple ports through a proprietary device with multiple channels. An incision is sited in the umbilicus to result in no visible scar. Objectives: The study aimed to evaluate the results of the treatment of acute appendicitis by applying single-port laparoscopic surgery. Methods: A clinical single-port laparoscopic appendectomy intervention of 122 patients, with the absence of a control group, was carried out by a sole surgeon at the Hue University of Medicine and Pharmacy Hospital, Hue, Vietnam, from August 2013 to December 2017. Research parameters included clinical history, physical examination, laboratory test, ultrasound imaging, intraoperative characteristics, and surgical outcomes. Results: We included 122 patients (64 males and 58 females) who met the inclusion criteria. The mean age was 31.28 ± 13.51 years (range, 16 - 73 years). The average BMI was 20.4 ± 1.39 kg/m2. All patients had abdominal pain, and the average duration of symptoms was 17.39 ± 5.41 hours (range, 6 - 31 hours). Five patients had a history of abdominal surgery. The mean diameter of appendicitis in ultrasound was 8.8 mm (range, 6 - 15 mm). Moreover, 89.3% of patients had an increase in white blood cells. The difficult location of appendicitis was 1.6% under the liver and 20.5% in the retrocecal region. In addition, 18.0% of retroperitoneal appendicitis and 6.6% of appendicitis were under cecalserosa. The mean operative time was 40.19 ± 14.67 mins (range, 23 - 150 min). Two cases (1.6%) required additional trocar insertion. Three cases (2.5%) had wound infection and no other complications. The median hospital stay was 3.64 ± 1.72 days (range, 2 - 13 days). Conclusions: Single-port laparoscopic surgery is the safe and effective treatment of acute appendicitis. This technique may be feasible for acute appendicitis with a difficult location.

SP3.1.13 Does Single-port laparoscopic appendicectomy provide better outcomes compared to conventional (three-ports) laparoscopic appendicectomy?

Abstract Aims To evaluate comparative outcomes of single port laparoscopic appendicectomy (SPLA) and conventional three-port laparoscopic appendicectomy (CLA) in the management of acute appendicitis. Methods A comprehensive systematic review of randomised controlled trials (RCTs) with subsequent meta-analysis of outcomes were conducted following PRISMA standards. Post-operative pain, cosmesis, need for an additional port(s), operative time, Post-operative complications, length of hospital stay(LOS), readmission, and reoperation were the evaluated outcome parameters. Results Sixteen RCTs reporting a total number of 2017 patients who underwent SPLA(n = 1009) or CLA(n = 1008) were included. SPLA showed higher cosmetic score (Mean Difference (MD) 1.11,P= 0.03) but significantly longer operative time (MD 7.08, P = 0.00001) compared to CLA. However, there was no significant difference between SPLA and CLA group in the postoperative pain score at 12 hours (MD -0.13,P=0.69), need for additional port(s) (Risk Ratio (RR)0.03, P = 0.07), postoperative ileus (RR 0.74,P=0.51), SSI ( RR 1.38, P = 0.28), Post-operative intra-abdominal collection (RR 0.00,P=0.62), LOS ( MD -2.41, P = 0.16), readmission to the hospital ( RR 0.45,P=0.22), and return to theatre (RR -0.00, P = 0.49). Subgroup analysis showed that operative time was comparable in adults only subgroup (P = 0.18) while it was significantly loner in paediatrics only subgroup(P = 0.00001). Moreover, LOS was shorter in adults only subgroup (P = 0.003) and no difference observed in paediatrics only subgroup (P = 0.93). Conclusion SPLA is associated with a slightly longer operative time; however, its efficacy and safety are comparable to CLA. Subgroup analysis showed that SPLA has better outcome in adults than paediatrics. Additionally, SPLA offers better post-operative cosmesis.

Modified glove single-port laparoscopic appendectomy versus conventional laparoscopic appendectomy in adolescent age under spinal anesthesia

The glove single-port laparoscopic appendectomy is a novel single incision laparoscopic technique (SILT) which is extremely cheaper than the other commercial devices. This study aimed to compare conventional laparoscopic appendectomy (CLA) and glove single port laparoscopic appendectomy (GSPLAP) in adolescents performed under spinal anaesthesia (SA). Forty-eight adolescents with uncomplicated appendicitis were included in the current study. All patients were randomized into 2 groups. Group A was operated upon by GSPLAP and group B, was operated upon using CLA. All cases were done under SA. Forty-eight adolescents were treated either by GSPLAP or LAP during the period from September 2017 to August 2018. They were 30 males and 18 females with a mean age 14.8 ± 2.2 years (range = 12–18 years). All procedures were completed laparoscopically without conversion. Only 2 cases of group A were converted to CLA. The mean operative time was 35.14 ± 12.14 min (range = 26–80 min) for CLA and 50.3 ± 11.2 min (range = 40–88 min) for GSPLAP. SA was successful in 44 cases [91.7%], while 4 patients [8.3%] were converted to general anaesthesia [GA]. Post SA headache was reported in 3 cases. Post-operative umbilical cellulitis occurred in two cases. Our modification of Glove Single Port is technically feasible. The GSPLAP is a new SILT which is cheaper than other single incision laparoscopic devices in the market. This study proved that SA for laparoscopic appendectomy (LAp) is a good substitute of GA in adolescents.

Single-port laparoscopic appendectomy for acute appendicitis during pregnancy.

Aim of Study:Acute appendicitis is the most common non-obstetric surgical problem in pregnant patients. As minimally invasive surgery has developed, minimising surgical trauma and improving cosmetic outcomes have led to the development of single-port laparoscopic surgery (SPLS). The aim of this study was to assess the feasibility and safety of SPLS for acute appendicitis during pregnancy.Patients and Methods:Between September 2014 and May 2016, 12 pregnant patients diagnosed with acute appendicitis and having single-port laparoscopic appendectomy were included in the study.Results:The median gestational age at surgery was 16 weeks (6–30 weeks). All operations were completed safely and without vascular or visceral injury. Four patients (33.3%) required conversion to a reduced-port laparoscopic surgery with 3 patients (25%) having a 5 mm port inserted because of perforated appendicitis with drain placement, and 1 patient (8.3%) having a 2-mm needle instrument insertion. Median operation time was 60 min (32–100 min), and a drainage tube was placed in 5 patients (41.7%). Median total length of incision was 2 cm (1.2–2.5 cm). The median time to soft diet initiation and length of stay in the hospital were 1 day (0–9 days) and 5 days (2–11 days), respectively. Two patients (8.0%) developed post-operative complications: One wound site bleeding and two surgical site infections. One case of abortion (8.3%) was noted on the post-operative day 1 and one case of imperforate hymen was noted after delivery.Conclusions:SPLS appendectomy is feasible and safe for treating patients with acute appendicitis during pregnancy.

Single-port laparoscopic appendectomy using a needle-type grasping forceps for acute uncomplicated appendicitis in children: Case series

IntroductionSingle-port laparoscopy has been used in any areas of surgery, including appendectomy, to reduce the operative stress and enhance postoperative recovery procedure. This paper introduces our attempt to perform single-port laparoscopic appendectomy using conventional laparoscoopic instruments and a needle-type grasping forceps (SLAN), which has dominant advantage in cosmetic appearance. MethodsWe report six pediatric patients who underwent SLAN for uncomplicated appendicitis from April to November 2019. SLAN was performed transumbilically, while conventional laparoscopic instruments and needle-type grasping forceps were both used. After routine intracorporeal appendectomy was completed, the pathological appendix was extracted through the single-port site, while a 10 mm trocar was used to avoid incision infectious. Clinical data and postoperative follow-up data were collected and analyzed to evaluate the feasibility, safety, and clinical outcomes of this novel technique. ResultsSLAN was successfully performed in all six pediatric patients. The median operative time, first exhaust time after surgery, pain score of postoperative day 1, and postoperative hospital stay were 69 (range, 50−85) min, 1.33 (range, 1–2) d, 0.83 (range, 0–3) score, 1.5 (range, 1–2) d, respectively. Neither intraoperative nor postoperative complications were noted, while no incision infectious, adhesive intestinal obstruction, and abdominal abscess were observed with 2–9 months follow up. DiscussionThough there are many methods to perform single-port laparoscopic appendectomy, the use of needle grasping forceps in laparoscopic appendectomy has been confirmed a new choice for uncomplicated appendicitis in children. ConclusionSLAN is a feasible and safe technique to treat acute uncomplicated appendicitis in children. To be emphasized, surgeons must strictly grasp the indications for this surgery.

Safety and feasibility of single-port laparoscopic appendectomy as a training procedure for surgical residents.

Background:Single-port laparoscopic appendectomy (SPLA) is one of the most commonly performed single-port surgeries worldwide. This study aimed to determine whether the performance of SPLA by residents without sufficient experience as operators of conventional LA (CLA) is safe and feasible.Patients and Methods:Records of patients who underwent LA between March 2017 and February 2018 at a hospital in Korea were retrospectively analysed. Patients aged <18 years or >80 years were excluded from the study. SPLA and CLA were performed by two 2nd-year residents (junior group) and three 3rd-year residents (senior group). Demographic data, perioperative variables and surgical outcomes were compared.Results:During the study period, 154 patients underwent LA (104 SPLA and 50 CLA) performed by surgical residents. No differences were found between the SPLA and CLA groups in demographic data or perioperative variables, except for the drain insertion rate. The SPLA group had significantly shorter mean operation times than did the CLA group. No significant difference was observed between the junior and senior groups in the mean operation time for LA. Perioperative outcomes were not significantly different between groups. Fewer women underwent SPLA performed by 2nd-year residents compared with SPLA performed by 3rd-year residents. However, there were no differences in other general characteristics or perioperative outcomes.Conclusions:SPLA was safe and feasible when performed by junior residents. Surgical residents with sufficient experience as assistants during laparoscopic appendectomies could perform SPLA safely. Furthermore, SPLA could serve as a teaching procedure for surgical residents.

Conventional Laparoscopic Appendectomy Versus Single-Port Laparoscopic Appendectomy, a Multicenter Randomized Control Trial: A Feasible and Safe Alternative to Standard Laparoscopy.

Background: Acute appendicitis represents one of the main causes of surgical emergencies. It can be approached as open appendectomy or laparoscopic appendectomy (LA). LA uses different modalities, such as conventional laparoscopic appendectomy (CLA) or single-port laparoscopic appendectomy (SPLA). The aim of this work is to compare the results of CLA versus SPLA in patients diagnosed with Acute Appendicitis. Materials and Methods: A comparative multicenter prospective study of patients undergoing LA with a clinical diagnosis of acute appendicitis was presented. They were divided into two groups (CLA group and SPLA group). Results: A total of n = 147 patients were included (72 CLA and 75 SPLA). Preoperative and intraoperative times were shorter for patients undergoing CLA (P = .002; P = .068). Postoperative and reinsertion time was lower for SPLA (P = .000; P = .0004). There were no differences in postoperative complications. The type of approach showed statistically significant differences with respect to pain within the first 12 hours of the postoperative period, as well as at discharge, while no differences were observed in relation to cosmetic satisfaction when the two approaches were compared. Conclusion: SPLA technique presented less intraoperative time, shorter time of labor reinsertion, and less postoperative pain. There were no statistically significant differences in postoperative complications.

Transumbilical Single-Incision Laparoscopic-Assisted Appendectomy (TULAA) Is Useful in Adults and Young Adolescents: Comparison with Multi-Port Laparoscopic Appendectomy.

Background and objectives: Single-port laparoscopic appendectomy (SLA) in most previous studies has used intracorporeal excision of the appendix and needed a longer operative time than multi-port laparoscopic appendectomy (MLA), although SLA does have the potential benefit of an almost invisible scar within the umbilicus. Some studies have reported that extracorporeal transumbilical single-incision laparoscopic-assisted appendectomy (TULAA) in children took a considerably reduced operative time compared to MLA. We adopted TULAA in adults, adding routine dissection of the peritoneal attachment of the appendix. The aim was to compare the operative outcomes between TULAA and MLA. Materials and Methods: Between March 2013 and January 2016, 770 patients with acute uncomplicated and complicated appendicitis from 15 to 75 years of age were enrolled retrospectively. The operation was performed as early (EA) and interval appendectomy (IA). Results: Operative time was shorter in the TULAA group than in the MLA group, except for IA. No open conversion occurred in the TULAA group, except one case of ileocecal resection for IA. No intra-abdominal fluid collection was found in the TULAA group. Extended resection (especially partial cecectomy) was performed less frequently in the TULAA group than in the MLA group for IA. Mean postoperative hospital stay was shorter in the TULAA group for uncomplicated appendicitis. When the data of the EA group and the IA group were compared, operative time was significantly shorter in the IA group for both MLA and TULAA. The open conversion rate and the complication rate tended to be lower in the IA group. Confined to IA, the TULAA group tended to have shorter mean initial, postoperative, and total hospital stays. Conclusions: TULAA can be a useful surgical alternative to MLA in adults and young adolescents, because it lacks open conversion and provides both a shorter operative time and a shorter postoperative hospital stay. TULAA is feasible for IA in that it showed a lower rate of extended resection and complications.

Development of a Two Port Laparoscopic Appendectomy Technique at a Rural Hospital.

Background Laparoscopic appendectomy (LA) is most commonly performed using two 5-mm and one 10/12-mm ports. Various attempts to reduce the number and size of ports have been made and new technologies such as single port LA have been introduced. Appendix and mesoappendix are usually divided with a stapler or energy device with electrocautery, clips, and endoloop being cheaper options. Patients and Methods This study includes 51 consecutive LAs performed at a rural hospital. Patients were divided into 4 groups: group 1 was the standard technique group (n=12), group 2 served as a “try-out” (n=12), group 3 served as feasibility group (n=12), and group 4 was the final patient cohort in which the optimized technique was preferably used (n=15). Results Median age of the study cohort was 35.4 (range: 6.2-80.6) years, and 55% of patients were male. Whereas in G1 all patients had standard port placement (10/12-mm, 2x5-mm), in an increasing number of patients in G2-4 only two 5-mm ports and the 2.3-mm Teleflex minigrasper were inserted. Usage of staplers and/or energy devices was reduced from 100% in G1 to 20% in G4, and in the majority of cases both the appendix and the vascular pedicle were secured with an endoloop. The new technique did not add time to the procedure or total OR time. No stump-leaks or surgical site infections were encountered in this series, and there were no conversions to open surgery. Cost savings when not using a stapler or energy device are approximately 400$ per case; the minigrasper added approximately 200$ to the case. Discussion LA with use of two ports and a portless needle grasper is feasible in the majority of cases and was associated with high patient satisfaction and excellent cosmetic results. Avoiding energy devices and staplers is cost saving; the endoloop securely controls appendix and mesoappendix.

A Prospective Randomized Controlled Trial of Single-Port and Three-Port Laparoscopic Appendectomy in Children.

Background: This study aimed to evaluate single-port laparoscopic appendectomy (SPLA) in comparison with three-port laparoscopic appendectomy (3PLA) in children about the extent of surgical trauma after SPLA and 3PLA measured by serum interleukin-6 (IL-6) and C-reactive protein (CRP) concentrations. Materials and Methods: A total of 50 patients with a median age of 11.5 were randomized to two groups. Experts in both methods performed the surgeries. The decision on the type of planned surgery was randomly determined. Serum IL-6 and CRP levels were measured using an enzyme-linked immunosorbent assay before, and at 12 and 36 hours after surgery. Furthermore, we compared operating time, hospital stay, postoperative pain, and complication rates. Results: The operative time in the 3PLA group was shorter than that in the SPLA group (P < .05). Preoperative IL-6 levels were not different between the two groups, but the rise (pre- versus postoperative) of IL-6 in the SPLA group was remarkably higher when compared with the 3PLA group (P < .05). Similar results were obtained for CRP; basal serum CRP levels were not different between the two groups, but the rise of CRP in the 3PLA group was significantly lower compared with that in the SPLA group. During the first 12 hours postoperative, the SPLA patients reported more severe postoperative pain and longer inpatient opiate usage was noted that after 3-PLA. Only one SPLA case was converted to 3PLA. There were no conversions to open surgery. The length of hospital stay and complication rate were not different between the two groups. Conclusions: SPLA in children is associated with longer operative times, increased pain level, and more severe surgical trauma as measured by postoperative CRP and IL-6 levels in comparison with a 3PLA. The two approaches were comparable regarding the length of hospital stay and complication rate.

Single-Incision, Two-Port Laparoscopic Appendectomy as an Alternative to Transumbilical Single-Port Laparoscopic Appendectomy.

PurposeWe designed a modified technique to perform an advanced procedure using conventional instruments and did not employ specialized single-incision laparoscopic surgery (SILS) port equipment. We compared postoperative results for transumbilical, single-port laparoscopic appendectomy (TUSPLA) and single-incision, 2-port laparoscopic appendectomy (SITPLA).MethodsThis retrospective study enrolled 77 patients who underwent TUSPLA or SITPLA to provide more minimally invasive surgery between May 2017 and April 2018. TUSPLA was performed in 39 patients and 38 underwent SITPLA. In the SITPLA group, two 5-mm trocars were inserted through the umbilicus and an extra puncture site was used for a left-handed instrument. Demographic characteristics, operative data, and postoperative outcomes were collected and compared between the groups.ResultsThe mean total operative time in the SITPLA group was shorter than in the TUSPLA group (p=0.003). The mean laparoscopic instrumental time was also shorter (p<0.001) in the SITPLA. The number of postoperative analgesics in the SITPLA group was less than in the TUSPLA group (p=0.002). The length of hospital day after surgery was shorter in the SITPLA group than in the TUSPLA group (p=0.008). There were no other significant differences between the groups.ConclusionSITPLA had a shorter operative time, required less pain management, and had a similar cosmetic outcome when compared with TUSPLA.

Laparoscopic Appendectomy versus Glove Single Port Laparoscopic Appendectomy in Pediatrics under Spinal versus General Anesthesia. A controlled Randomized Study

Background: The glove single-port laparoscopic appendectomy it is a novel SILS technique which is extremely cheaper than the other commercial devices. Objective: this study aimed to compare between conventional laparoscopic appendectomy (CLAP) and glove single port laparoscopic appendectomy (GSPLAP) under tow different anesthetic technique. Patients and Methods: this study of laparoscopic appendectomy was conducted over thirty six children (n=36). All patients were randomized into 4 groups by a random-number table sequence after giving informed parental consent. The allocations will be contained in opaque sequentially numbered closed envelopes and every patient drew an envelope. Results: Two cases of GSPLAP were converted to multi-port due to difficult accessibility of the appendix and adhesions (suppurative appendicitis). The Mean operative time for CLAP was significantly lower than GSPLAP procedure. For CLAP was 38.39±10.12 min (ranged from 26 to 75 min) and was 49.11±11.98 min (ranged from 38 to 86 min) for GSPLAP. We observed that GSPLA was less painful significantly than CLAP for the first postoperative hours (≤3hrs) the time of postoperative needs of analgesia in pt. underwent LA under SA is delayed. Conclusion: Using a combination of 0.5% hyperbaric bupivacaine and a fentanyl provided effective anesthesia for laparoscopic appendectomy with low-pressure Co2 Pneumoperitoneum. It offers better pain management for the patients, earlier recovery and less operating room costs. We recommend an increasing use of spinal anesthesia for laparoscopic appendectomy especially in patients with risks for general anesthesia.
