Abstract
Situs inversus, an uncommon disorder, causes the orientation of asymmetric organs to be opposite to that of normal anatomy. It can be either partial, affecting only the thoracic or abdominal cavities, or full, involving the transposition of both the thoracic and abdominal organs. A 31-year-old Ethiopian male patient presented with migratory abdominal pain in the left lower quadrant for 3 days. Associated with the pain, he experienced symptoms of nausea, vomiting of ingested matter, and loss of appetite. Investigations were consistent with left-sided appendicitis with situs inversus totalis. Therefore, the patient was operated on and discharged with no perioperative complications. Appendicitis is a rare cause of left lower quadrant pain. In order to reduce the delay in patient treatment and avoidable perioperative complications, emergency physicians, radiologists, and surgeons must become more knowledgeable about situs inversus and left side appendicitis.

Abstract
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.

Abstract
AA is a frequent surgical condition that demands urgent intervention. It accounts for approximately 6% of all emergency department visits. Situs inversus is a rare condition in which the orientation of asymmetric organs is a mirror image of normal anatomy. It can be partial (involving either the abdominal or thoracic cavities) or complete (situs inversus totalis: transposition of both abdominal and thoracic organs). SIT is very rare, with an incidence of 1 per 5000 to 10,000 live births. It is inherited in an autosomal recessive pattern with incomplete penetrance. LSAA is very rare and can happen in association with other congenital abnormalities such as situs inversus, midgut malrotation (MM), or a usually long right-sided appendix projecting into the left lower quadrant. SIT is responsible for greater than 67% of left-sided appendicitis cases. Due to atypical clinical presentation, the diagnosis of AA can be difficult and often delayed. Hence, a complete medical history, physical examination, laboratory tests, and imaging tools are necessary to reach a correct diagnosis in a timely manner and prevent complications like abscesses, perforations, and peritonitis. We report a case of a 50-year-old male with symptoms of left lower abdominal pain along with fever, nausea, vomiting, and loose stools that were later diagnosed as LSAA in the setting of SIT.

Abstract
BACKGROUND the barriers to implement emergency laparoscopy in public teaching hospitals involve issues such as resident learning curves and resource costs and availability. This study was designed to describe the issues facing the implementation of laparoscopic approach for acute appendicitis over 15 years in a single academic center in Brazil. MATERIALS AND METHODS retrospective study of patients undergoing emergency appendectomy from 2004 to 2018. Clinical data were compared to four major actions implemented in the emergency surgical service: minimally invasive surgery training for residents (2007), laparoscopic stump closure using metal clips (2008), 24/7 availability of laparoscopic instruments for emergency surgeries (2010), and third-party contract for maintenance of the laparoscopic instruments and implementation of polymeric clips for stump closure (2013). We evaluated the increase in laparoscopic appendectomy after the implementation of those major changes. RESULTS we identified 1168 appendectomies during the study period, of which 691 (59%), 465 (40%), and 12 (1%) were open, laparoscopic, and converted, respectively. The implementation of the major changes since 2004 resulted in an increase of laparoscopic appendectomies from 11% in 2007 to 80% in 2016. These actions were decisive in the widespread use of laparoscopy for acute appendicitis (p<0.001). The standardization of the hem-o-lok clip in the treatment of the appendiceal stump made the procedure more feasible, reducing the surgical time using laparoscopic access and increasing the team's adherence, so that this became the route of choice in about 85% of cases in the period from 2014 to 2018, 80% performed by 3rd year resident physicians. No intraoperative complications were noted related to laparoscopic access, even in more complicated appendicitis. There was no mortality reported, no reoperations or readmissions to hospital during a 30-day postoperative period. CONCLUSION the development of a feasible, reproducible, and safe technical standardization, associated with continuous cost optimization, are the cornerstones for a consistent and viable change in the current practice for appendectomies in middle and lower-income countries.

Acute appendicitis and situs viscerum inversus: radiological and surgical approach-a systematic review. Eur J Med Res 2023; 28:85. [PMID: 36805741 PMCID: PMC9940389 DOI: 10.1186/s40001-023-01059-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Accepted: 02/09/2023] [Indexed: 02/22/2023] Open
Abstract
INTRODUCTION Acute appendicitis is one of the most frequent intra-abdominal diseases requiring emergency surgical consult and treatment. The diagnosis of this condition is based on clinical features and radiologic findings. One-third of patients with acute appendicitis present unusual symptoms. There are several circumstances that may cause misdiagnosis and unclear prognostic prediction. Among these, situs viscerum inversus totalis and midgut malrotation can be challenging scenarios, leading to a delay in treatment, especially when these conditions are unknown. We decided to carry on a systematic review of published cases of acute appendicitis in the context of anatomical anomalies. METHODS We used the MESH terms "appendicitis" AND "situs inversus" AND/OR "gut malrotation" to search for titles and abstracts. Inclusion criteria were patients with clinical and/or radiological diagnosis of acute appendicitis, with conservative or surgical management and with preoperative/intraoperative findings of situs viscerum inversus or gut malrotation. Additionally, previous reviews were examined. Exclusion criteria of the studies were insufficient patient clinical and demographic data. RESULTS We included in this review 70 articles concerning 73 cases of acute appendicitis with anatomical anomaly. Patients were aged from 8 to 86 years (median: 27.0 years). 50 were male and 23 were female. 46 patients (63%) had situs viscerum inversus, 24 (33%) had midgut malrotation, 2 (2.7%) had Kartagener's syndrome, one of them (1.4%) had an undetermined anomaly In 61 patients the anatomical anomaly was unknown previously (83.6%), while 16,4% already were aware of their condition. CONCLUSION Acute appendicitis can occur in association of rare anatomical anomalies and in these cases diagnosis can be challenging. Situs viscerum inversus and midgut malrotation should always be considered in the differential diagnosis of a patient with left lower quadrant pain, especially in younger population. Besides clinical features, it is fundamental to implement the diagnostic progress with radiological examination. Laparoscopic approach is useful to identify and treat acute surgical emergency and it is also a diagnostic tool and can be tailored in order to offer the best exposition of the operatory field for each single case.

Abstract
Abdominal pain due to acute appendicitis in one of the most causes of access to Emergency Room requiring surgical consult and treatment. The occurrence of anatomical anomalies should be considered especially when clinical and imaging features are misleading. In these cases laparoscopic surgery can be a safe tool in order to confirm uncertain diagnosis. We report a case of acute appendicitis in a 23-year-old Caucasian men with situs viscerum inversus detected on radiological investigation. Laparoscopic approach was used to confirm the diagnosis and to perform appendectomy. Trocars placement was tailored for this peculiar case. Situs viscerum inversus and midgut malrotation should be taken into consideration in patients with findings of the physical examination suspicious for left-sided acute appendicitis.

[PMID: 32802324 PMCID: PMC7419254 DOI: 10.1016/j.amsu.2020.07.058] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Accepted: 07/27/2020] [Indexed: 12/15/2022] Open
Abstract
Background Closure of the appendiceal stump is a key step performed during laparoscopic appendicectomy. Inadequate management of the appendiceal stump has the potential to cause significant morbidity. Several methods of stump closure have been described, however high-level evidence is limited. We performed a systematic review evaluating clinical outcomes and quality of the evidence for the methods of appendiceal stump closure. Methods A systematic literature search was performed using Medline, Embase, Cochrane Database and Google Scholar to identify studies comparing appendiceal stump closure methods in laparoscopic appendectomy for acute appendicitis from inception to October 2019. Data regarding operative duration, peri-operative complications, length of stay and costs were collated from all included studies. Results From 160 identified studies, 19 met the inclusion criteria. Endoloops and endoclips provide equivalent clinical outcomes at lower cost, while operative duration was shortest with endoclip closure. Endostapler devices have the lowest rate of peri-operative complications (3.56%), however their cost limits their regular use in many healthcare environments. Post-operative complication rate and length of stay were similar for all stump closure methods. Conclusion: Although there are no significant differences in method of stump closure in laparoscopic appendectomy, closure with endoclips provides the shortest operative duration. There is a need for robust and standardized reporting of cost data when comparing stump closure methods, together with higher level evidence in the form of multi-centre randomized controlled trials before firm conclusions can be drawn regarding the optimal method of stump closure. Currently there is no robust higher order evidence which assesses clinical outcomes, cost and time efficiency of methods of stump closure in laparoscopic appendicectomy. This is the first systematic review to investigate clinical outcomes, cost and quality of current evidence for all methods of laparoscopic appendiceal stump closure in acute appendicitis. No difference was observed in methods of stump closure in complication rate, length of stay, cost, and time efficiency. Endostaplers appear to provide most robust closure, albeit at a higher economic cost. Endoloops appear to provide efficient and successful closure, and are currently the most frequently studied method of closure.

Abstract
Purpose This study was aimed at reporting our experience with single-incision laparoscopic appendectomies (SILA) performed by a surgical resident, and to evaluate the safety and feasibility of the procedure, together with a comparison of the outcomes of the same procedure performed by a staff surgeon. Methods We conducted a retrospective case series analysis of 60 consecutive patients who underwent SILA. Two surgeons, an attending staff surgeon and a second-year surgical resident, performed the SILA procedures. SILA procedures performed by the resident were intraoperatively guided and supervised by the staff surgeon. Results A total of 60 case-matched patients with acute appendicitis underwent a SILA performed by either the resident or attending staff. There was no difference in patient demographics between the two groups of patients. The mean operation time was longer in the resident group than in the staff group (43.2±6.0 minutes vs. 32.9±10.5 minutes, p<0.001). There was no significant difference in the operative data between the two groups. No conversion to an open procedure occurred in either group. Postoperative pain, time to onset of oral intake, and number of days of postoperative hospital stay were similar in both groups. Conclusion SILA procedures performed by a resident are safe and feasible despite longer operation times. Perioperative supervision and guidance by an attending staff surgeon may facilitate surgical outcomes.

Laparoscopic Lavage Versus Suction Only in Complicated Acute Appendicitis: A Prospective Randomized Control Trial. Int Surg 2018.

Abstract
Background:
Laparoscopic appendectomy for complicated appendicitis presents a challenge with concerns about pelvic collections. It is unclear whether lavage or if simple suctioning of pus influences complications.
Methods:
A prospective, single,-blinded, randomized control trial was conducted. Patients with suspected acute appendicitis were consented. Those found to have complicated appendicitis (perforation, localized pus, or four-quadrant pus) at laparoscopy were randomized to suction or lavage. Exclusions included conversions and drainage of abscess only. Lavage consisted of 3 liters of lavage. Intra-abdominal abscess that required reintervention (i.e., relook, percutaneous drainage) was the primary outcome. Hospital stay and return of bowel function were also recorded.
Results:
A total of 213 patients were assessed for eligibility. We excluded 157 patients, as they had simple appendicitis; 7 patients were converted to laparotomies; 5 had abscesses but the appendix was not removed. We analyzed 86 patients. The mean age was 26.6 years (14–74). We lavaged 42 (48.8%) patients and 44 (51.2%) were suctioned. Four-quadrant pus was present in 26 (30.2%) of the patients overall. Complications developed in 20 (47.5%) of the patients that were lavaged versus 12 patients (27.1%) with suction only. The difference did not reach significance due to sample size (P = 0.0739). Operative time was longer in the lavage group by 30 minutes (P = 0.086). If a complication developed, then the hospital stay was significantly prolonged 13.5 days versus 5 days (P < 0.001). The study was stopped by the internal review board due to the excess risk with lavage.
Conclusions:
This exploratory study into lavage versus suction only in complicated appendicitis revealed potential harm with lavage. The study was stopped prematurely by the internal review due to the excess risk experienced by the lavage group, thus the study did not reach statistical power. If a patient with complicated appendicitis developed any complication, hospital stay was longer.

Abstract
BACKGROUND Conventional three-incision laparoscopic appendectomy (CTLA) is considered the new golden standard for the treatment of acute appendicitis. However, single-incision laparoscopic appendectomy (SILA) can further reduce the number of abdominal incisions and visible scars. METHODS Major databases were researched for randomized clinical trials (RCTs) comparing SILA and CTLA for acute appendicitis from January 1983 and to March 2015. The technical feasibility, effectiveness, and safety between SILA and CTLA were compared. Pooled odds ratios (ORs) and weighted mean differences (WMDs) with 95% confidence intervals (CIs) were calculated using fixed- or random-effects models. RESULTS In total, 11 RCTs with 1489 patients were analyzed. The patients in the SILA group had a significantly shorter hospital duration (WMD: -0.63; 95% CI: -1.04, -0.21; P = 0.003) and return to activity (WMD: -2.91; 95% CI: -5.45, -0.37; P = 0.02) but experienced a longer operating time (WMD: 6.56; 95% CI: 3.55, 9.58; P < 0.0001) and higher rate of conversion (OR: 6.82; 95% CI: 3.14, 14.79; P < 0.00001). There were no differences between the two groups in visual analog pain scores, doses of analgesics, overall complication rates, wound infection, or cosmesis (all P > 0.05). CONCLUSIONS SILA is a safer and more effective than CTLA in both pediatric and adult patients.

Abstract
INTRODUCTION The objective of this study was to compare operative peritoneal irrigation versus suction alone during laparoscopic appendectomy in adult patients; our hypothesis was that the two methods are equivalent in terms of rate of post-operative intra-abdominal abscess. There has been only one prospective, randomized, superiority trial in children, that showed non-significant difference in the rate of intra-abdominal abscess comparing irrigation to suction alone during laparoscopic appendectomy for perforated appendicitis. Non-significant difference in a superiority trial does not imply equivalence. METHODS This was a single-institution, prospective, randomized controlled equivalence study based on a null-hypothesis of non-equivalence between irrigation and suction alone. Adult patients with intra-operative findings of an acutely inflamed appendix, with suppuration or perforation localized to the right iliac fossa, paracolic gutter or pelvis were randomized to irrigation or suction alone. The primary endpoint was the rate of intra-abdominal abscess. An unconditional exact test of equivalence was used to test the null-hypothesis. RESULTS Eighty-one patients were included for analysis. Two (5%) of 40 patients in the irrigation group and two (4.9%) of 41 in the suction-only group developed postoperative intra-abdominal abscess. The 95% confidence interval for the difference between the two groups was -0.1200 to 0.1244, captured within the pre-defined δ limits (-0.15, 0.15). With reference to the rate of intra-abdominal abscess, equivalence was demonstrated between irrigation and suction-only techniques. CONCLUSIONS In patients with suppurative or perforated appendicitis, the rate of intra-abdominal abscess is equivalent between groups treated with peritoneal irrigation and suction alone.

Abstract
BACKGROUND Appendicular stump closure is a crucial step during laparoscopic appendectomy. Recently, endoclips (ECs) have been described for ligation of the appendicular stump. The objective of this review was to compare outcomes with EC versus endoligature (EL) for appendiceal stump closure during laparoscopic appendectomy. MATERIALS AND METHODS A literature search of Medline, Embase, Cochrane Database, and Google Scholar was performed to identify studies comparing use of EL versus EC in laparoscopic appendectomy between January 1992 and September 2013. Reviews of each study were conducted, and data were extracted. The random-effects model was used to combine data, and between-study heterogeneity was assessed. RESULTS Seven of the 101 identified studies met the inclusion criteria: four randomized controlled trials and three case controlled series. For the primary outcome of perioperative and postoperative complications, there was no significant difference between the EC versus EL groups. No differences were noted in length of hospital stay. However, a significant reduction in operative time was observed with EC as opposed to EL (standardized mean difference=-0.90, 95% confidence interval=-1.26 to -0.54, P=.001). Moreover, EC procedures were less expensive than EL procedures. CONCLUSIONS EC application in the management of appendiceal stump during laparoscopic appendectomy appears to be simple, efficacious, safe, and a cost-effective alternative.

Abstract
BACKGROUND Single-port laparoscopic appendectomy (SPLA) has gained widespread acceptance and is increasingly performed. The evidence assessing the safety and efficacy of SPLA compared with conventional laparoscopic appendectomy (CLA) is growing; however, very few randomized trials exist and individual studies often have small patient numbers with varying results. We integrated the available data to enhance the current literature by comparing these techniques. METHODS A systematic review of the literature was performed to identify studies comparing SPLA and CLA. Operative parameters, postoperative outcomes, and postoperative complications were evaluated. Meta-analysis was performed using Review Manage Version 5.0 software. RESULTS Fifteen studies matched the selection criteria, including 1560 patients (46.1% SPLA, 53.9% CLA). SPLA was associated with longer operative time compared with CLA procedure (P=0.001). There were no significant statistical differences between the SPLA and CLA groups in terms of postoperative outcomes including postoperative visual analog scale pain scores (P=0.12), time to return to diet (P=0.45), time to flatus (P=0.89), leukocyte count (P=0.86) and C-reactive protein level (P=0.70) evaluation after operation, cosmetic satisfaction level (P=0.95), and length of hospital stay (P=0.16). The overall complication rates were not significantly different between the 2 groups (P=0.44). There was no evidence to suggest heterogeneity of trial results. CONCLUSIONS SPLA shows no benefit over CLA, including even parameters such as postoperative pain and cosmetic results, and, therefore, there is no indication to use this approach over standard laparoscopic appendectomy. SPLA does take longer to perform. Further studies are needed to confirm that the procedure is more costly.

Abstract
INTRODUCTION A transumbilical laparoscopic-assisted single-channel, single-port procedure was introduced during laparoscopic interval appendectomy for mass-forming appendicitis in children. The aim of this study was to evaluate the results of the original laparoscopic interval appendectomy. METHODS This study analyzed 31 children who underwent laparoscopic interval appendectomy using a single-channel, single-port procedure. The appendectomy was usually planned 8-12 weeks following initial conservative treatment. The procedure was a single-channel surgery using a 12-mm single port. Both a 5-mm telescope and grasper were inserted simultaneously into the single channel. The grasper held the appendix, and an extracorporeal appendectomy was performed. RESULTS Appendectomy was planned for 29 patients, as 2 patients deviated from the protocol. The procedure was successful in 21 patients (72.4%). An accessory port was necessary in eight patients, two of whom successfully underwent laparoscopic surgery; the remaining six were converted to open appendectomy. The average length of surgery was 43 min in the single-channel, single-port procedure. No postoperative complications occurred in any patient. CONCLUSION The single-channel, single-port procedure was successfully performed in over 70% of the patients. This preliminary retrospective analysis indicates that the procedure is safe and potentially beneficial in children with mass-forming appendicitis who require laparoscopic interval appendectomy.

Abstract
INTRODUCTION Laparoscopic appendectomy is probably the technique of choice in acute appendicitis. Single port laparoscopic surgery (SILS) has been proposed as an alternative technique. The objective of this study is to compare the safety and efficacy of SILS against conventional laparoscopic appendectomy (LA). MATERIAL AND METHODS From January 2011 to September 2012, 120 patients with acute appendicitis were prospectively randomized; 60 for SILS and 60 for LA. Patients between 15 to 65 years were selected, with onset of symptoms less than 48h. We compared BMI, surgery time, start of oral intake, hospital stay, postoperative pain, pathology and costs. RESULTS The median age, BMI, sex and time of onset of symptoms to diagnosis were similar. There were no statistically significant differences in the operative time, start of oral intake or hospital stay. There was a significant difference in postoperative pain being higher in SILS (4±1.3) than in LA (3.3±0.5) with a P=.004. Flemonous appendicitis predominated in both groups in a similar percentage. A total of 3 cases with intra-abdominal abscess (SILS 2, LA 1) required readmission and resolved spontaneously with intravenous antibiotic treatment. One case of SILS required assistance by a 5mm trocar in the RLC for drainage placement. The cost was higher in SILS due the single port device. CONCLUSION SILS appendectomy is safe, effective and has similar results to LA in selected patients, and although the cost is greater, the long term results will determine the future of this technique.

Abstract
PURPOSE Single-incision laparoscopic surgery has recently received more attention. We developed a novel simple technique of gasless transumbilical single-incisional laparoscopic-assisted appendectomy (TUSILAA) and retrospectively analyzed our initial experience. METHODS TUSILAA has been attempted in 50 consecutive patients with acute appendicitis. The vertical incision through the umbilicus was used for laparoscopic access and the abdominal wall was lifted by a Kent retractor set system. RESULTS Our technique was successful in 45 out of 50 (90 %) patients. The median operating time was 59 min (range 35-140). The median length of postoperative hospital stay was 4 days (range 2-12). None of the cases were converted to open appendectomy. There were no perioperative surgical complications. CONCLUSIONS Our novel technique, gasless TUSILAA, is safe and feasible with acceptable operative time and excellent cosmetic result. Furthermore, this procedure has the advantage of cost-effectiveness since any disposable instruments including trocars, staplers, or expensive devices are not required. Therefore, this could be used as the first-choice surgical procedure for selected patients with uncomplicated acute appendicitis.

Abstract
McBurney’s procedure represented the gold-standard for acute appendicitis until 1981, but nowadays the number of laparoscopic appendectomies has progressively increased since it has been demonstrated to be a safe procedure, with excellent cosmetic results and it also allows a shorter hospitalization, a quicker and less painful postoperative recovery. The aim of this editorial was to perform a review of the literature in order to address controversial issues in the treatment of acute appendicitis.

Abstract
Laparoscopic procedures for removal of the appendix by the three-port technique as an alternative to conventional appendicectomy have gained wide popularity, but they have been criticized for technical difficulty, more time consumption, and high cost. We have compared conventional three-port laparoscopic appendicectomy (LA) and laparoscope-assisted appendicectomy (LAA). In period from August 2010 to January 2012, 77 patients underwent appendicectomy by a minimally invasive procedure (39 LA and 38 LAA), at Medical College and Hospital, Kolkata. All the 39 cases of LA were completed successfully, but of the 38 cases, LAA could be completed only in 32 cases. Of the six cases where LAA could not be completed, five were converted to LA [three because of excessive body mass index (BMI) and two because of bleeding]. One case had to be converted to open appendicectomy because of excessive bleeding. In LA, the mean duration of surgery was less than that in LAA (18.18 versus 24.39 min). Wound infections were more common in LAA compared to LA (six versus two). Severe postoperative pain was present in eight cases in LAA compared to two in LA. On day 2, 79.487 % patients undergoing LA were discharged compared to 28.947 % in LAA. LA is better as a minimally invasive procedure. LAA can only be done in patients with lower BMI, is more time consuming, has more complications, more incidence of postoperative pain, wound infections, and longer hospital stay.

Abstract
BACKGROUND The objective of this study is to evaluate the incidence of intra-abdominal collections (IACs) in all patients undergoing laparoscopic (LA) and open appendicectomy (OA) from April 2009 to October 2011 in a district general hospital with expertise in minimally invasive surgery (MIS). METHODS A retrospective review of all patients undergoing appendicectomy in the specified time period was carried out. IACs were identified from various in-hospital data resources. Severity of appendicitis was assessed from histology reports. RESULTS 516 patients were identified, of whom 242 (47 %) underwent OA and 274 (53 %) LA. Twenty-six (5 %) patients were found to have IACs postoperatively. Fifteen (5.5 %) IACs were identified in the laparoscopic group and 11 (4.5 %) in the open group. There was no statistically significant difference in the risk of developing IACs in open versus laparoscopic groups [odds ratio (OR) 1.22, confidence interval (CI) 0.55-2.70, P = 0.63]. Patients were twelve times more likely to develop IACs with an appendix identified as being necrotic or perforated on histology (OR 12.24, CI 5.29-28.32, P < 0.0001). There was a trend towards shorter total hospital stay in the LA (3.58 days, CI 3.0-4.1 days) compared with OA (4.31 days, CI 3.7-4.9 days, P = 0.082) group, although this was not statistically significant. CONCLUSIONS Increased rates of IAC following LA have been identified in some studies. Our series shows that, in a centre with adequate MIS experience, the IAC rate following LA is comparable to that of the open approach and should not deter surgeons with adequate support and resources.

Abstract
INTRODUCTION Although appendectomies are frequently performed and new procedural techniques have emerged, no nationwide analysis exists after the cessation of the German quality control in 2004. METHODS One thousand eight hundred seventy surgical hospitals in Germany were asked to answer questions anonymously concerning the size of the department, applied procedural techniques, various technical details, as well as the approach to the intraoperative finding of an inconspicuous appendix. RESULTS We received 643 questionnaires (34.4 %) for evaluation. Almost all hospitals (95.5 %) offer laparoscopic appendectomy (LA), 15.4 % offer single-port (SPA), and 2.2 % (hybrid-) NOTES technique (NA). LA is the standard procedure in 85.2 % of male and in 89.1 % for female patients. In an open procedure (OA), the appendix and mesoappendix are mostly ligated (93.8 and 91.5 %). A Veress needle and open access are employed equally for LA. In 66.6 % of LA, the appendix is divided using an Endo-GIA, the mesoappendix in 45.5 % with bipolar coagulation. Almost half of the hospitals routinely flush the site in OA and LA. In open surgery with an inconspicuous appendix but a pathological finding elsewhere in the abdomen, it is resected "en principe" in 64.7 % and in the absence of any pathological finding in 91.2 %. For laparoscopic procedures, the numbers are 54.8 and 88.4 %. CONCLUSIONS Most German hospitals perform appendectomies laparoscopically regardless of patients' gender. Usage of an Endo-GIA is widely established. SPA has not gained much acceptance, nor is NA widely used yet. In the absence of any pathological findings in particular, the macroscopically inconspicuous appendix results in an appendectomy "en principe" in most German hospitals.

Abstract
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.
