Abstract
INTRODUCTION Evaluating groin pain still evades many clinicians at times as they have difficulty determining the cause of pain when no true hernia exists. This study's aim was to evaluate a simple and novel scoring system which is reproducible, to help determine whether conservative measures or surgery is recommended for the management of groin pain attributable to inguinal disruption. MATERIAL & METHODS A retrospective analysis of all patients from 2018 to 2020 that underwent surgery or conservative management for inguinal disruption with at least a 1-year follow-up were evaluated. The scoring system is based on MRI and ultrasound imaging as well as clinical findings, with scores given from - 2 to + 2 based on the defined findings listed. A maximum total of four points scored for each assessment was used. Sensitivity and specificity analysis was conducted for each potential score cut off point. RESULTS A total of 172 patients were evaluated with 33 patients (19%) undergoing conservative management and 139 patients (81%) undergoing surgery. The median SPoRT score for the surgery group was 2.0 (1.0, 3.0), and - 1.0 (- 3.0, 0.0) in the physiotherapy group which was a significant difference (p < 0.001). An optimal cut off of ≤ 0 for physio and ≥ 1 for surgery was established, yielding a sensitivity of 90.9% (95% CI 75.7%-98.1%), a specificity of 89.2% (95% CI 82.8%-93.8%) and an area under the curve (AUC) of 0.936 (95% CI 0.874-0.997). DISCUSSION SPoRT score of ≤ 0 can recommend a patient should undergo conservative measures or physiotherapy as a mainstay of treatment with a score of ≥ 1 recommending surgery. Further validation of the score is necessary.

Abstract
OBJECTIVE To find out the mesh fixation technique that minimises chronic pain in Lichtenstein hernioplasty. Mesh fixation may affect chronic pain and recurrence after inguinal hernia surgery, but long-term results of comparative trials are lacking. METHODS Lichtenstein hernioplasty was performed under local anaesthesia on 625 patients in day care units. The patients were randomised to receive either a cyanoacrylate glue (n = 216), self-gripping mesh (n = 202) or non-absorbable 3-0 polypropylene sutures (n = 216) for the fixation of mesh. A standardised telephone interview or postal questionnaire was conducted 5 years after the index operation. The patients with complaints suggesting recurrence or chronic pain (visual analogue scale ≥ 3, 0-10) were examined clinically. The rate of occasional pain, chronic severe pain, recurrence, re-operations, daily use of analgesics, overall patient satisfaction and sensation of a foreign object were recorded. RESULTS A total of 82% of patients (n = 514) completed the 5-year audit including 177, 167 and 170 patients in the glue, self-fixation and suture groups, respectively. There were no significant differences in the incidence of pain (7-8%), operated recurrences (2-4%), overall re-operations (4-5%), need for analgesics (1-2%), patient's satisfaction (93-97%) or in the feeling of a foreign object (11-18%) between the study groups. CONCLUSION The choice of the mesh or fixation method had no effect on the overall long-term outcome, pain or recurrence of hernia. Less penetrating fixation (glue or self-gripping mesh) is a safe option for the fixation of mesh in Lichtenstein hernia repair.

Abstract
Abstract
Background
Sportsman's hernia/athletic pubalgia is a recognized cause of chronic groin pain in athletes. Both open and laparoscopic surgical repairs have been described for treatment, but there are no comparative studies. The hypothesis here was that relief of pain would be achieved earlier in patients treated with open minimal suture repair than totally extraperitoneal repair.
Methods
A randomized multicentre trial in four European countries was conducted to compare open minimal suture repair with totally extraperitoneal repair. The primary endpoint was complete relief of pain (visual analogue scale (VAS) score 20 or less on a scale from 0 to 100 mm) at 1 month. Secondary endpoints included complications, time to return to sporting activity, and number of patients returning to sport within 1 year.
Results
A total of 65 athletes (92 per cent men) with a median age of 29 years were enrolled (31 open repair, 34 totally extraperitoneal repair). By 4 weeks after surgery, median preoperative VAS scores had dropped from 70–80 to 10–20 in both groups (P < 0·001). Relief of pain (VAS score 20 or less) during sports activity 4 weeks after surgery was achieved in 14 of 31 patients after open repair and 24 of 34 after totally extraperitoneal repair (P = 0·047). Return to full sporting activity was achieved by 16 and 18 patients respectively after 1 month (P = 0·992), and by 25 versus 31 after 3 months (P = 0·408).
Conclusion
Totally extraperitoneal repair was less painful than open repair in the first month, but otherwise both procedures were similarly effective in treating chronic pain due to sportsman's hernia. Registration number: NCT02297711 ( http://www.clinical.trials.gov).

Optimising the antibiotic treatment of uncomplicated acute appendicitis: a protocol for a multicentre randomised clinical trial (APPAC II trial). BMC Surg 2018; 18:117. [PMID: 30558607 PMCID: PMC6296129 DOI: 10.1186/s12893-018-0451-y] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Accepted: 11/28/2018] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Based on epidemiological and clinical data acute appendicitis can present either as uncomplicated (70-80%) or complicated (20-30%) disease. Recent studies have shown that antibiotic therapy is both safe and cost-effective for a CT-scan confirmed uncomplicated acute appendicitis. However, based on the study protocols to ensure patient safety, these randomised studies used mainly broad-spectrum intravenous antibiotics requiring additional hospital resources and prolonged hospital stay. As we now know that antibiotic therapy for uncomplicated acute appendicitis is feasible and safe, further studies evaluating optimisation of the antibiotic treatment regarding both antibiotic spectrum and shorter hospital stay are needed to evaluate antibiotics as the first-line treatment for uncomplicated acute appendicitis. METHODS APPAC II trial is a multicentre, open-label, non-inferiority randomised controlled trial comparing per oral (p.o.) antibiotic monotherapy with intravenous (i.v.) antibiotic therapy followed by p.o. antibiotics in the treatment of CT-scan confirmed uncomplicated acute appendicitis. Adult patients with CT-scan diagnosed uncomplicated acute appendicitis will be enrolled in nine Finnish hospitals. The intended sample size is 552 patients. Primary endpoint is the success of the randomised treatment, defined as resolution of acute appendicitis resulting in discharge from the hospital without the need for surgical intervention and no recurrent appendicitis during one-year follow-up. Secondary endpoints include post-intervention complications, late recurrence of acute appendicitis after one year, duration of hospital stay, pain, quality of life, sick leave and treatment costs. Primary endpoint will be evaluated in two stages: point estimates with 95% confidence interval (CI) will be calculated for both groups and proportion difference between groups with 95% CI will be calculated and evaluated based on 6 percentage point non-inferiority margin. DISCUSSION To our knowledge, APPAC II trial is the first randomised controlled trial comparing per oral antibiotic monotherapy with intravenous antibiotic therapy continued by per oral antibiotics in the treatment of uncomplicated acute appendicitis. The APPAC II trial aims to add clinical evidence on the debated role of antibiotics as the first-line treatment for a CT-confirmed uncomplicated acute appendicitis as well as to optimise the non-operative treatment for uncomplicated acute appendicitis. TRIAL REGISTRATION Clinicaltrials.gov , NCT03236961, retrospectively registered on the 2nd of August 2017.

Abstract
OBJECTIVE Upper gastrointestinal bleeding (UGIB) is a common emergency, with in-hospital mortality between 3 and 14%. However, the long-term mortality and causes of death are unknown. We investigated the long-term mortality and causes of death in UGIB patients in a retrospective single-centre case-control study design. METHODS A total of 569 consecutive patients, aged ≥18 years, admitted to Kuopio University Hospital for their first endoscopically verified UGIB during the years 2009-2011 were identified from hospital records. For each UGIB patient, an age, sex and hospital district matched control patient was identified from the Statistics Finland database. Data on endoscopy procedures, laboratory values, comorbidities and medication were obtained from patient records. Data on deaths and causes of death were obtained from Statistics Finland. RESULTS In-hospital mortality of UGIB patients was low at 3.3%. The long-term (mean follow-up 32 months) mortality of UGIB patients was significantly higher than controls (34.1 versus 12.1%, p < .001). During the 6 months following UGIB, the risk of death compared to controls was highest (HR 19.2, 95% CI 7.0-52.4, p < .001) and remained higher up to 3 years after the bleeding. Beyond 3 years' follow-up, there was no difference in mortality between the groups (HR 0.7, 95% CI 0.4-1.6, p = .436). During the first 3 months after the UGIB episode, mortality was related to gastrointestinal diseases; after 3 months, the causes of death were related to comorbidities and did not differ from causes of death in controls. CONCLUSIONS UGIB patients have three times higher long-term mortality than population controls.

Abstract
Background and Aims: To assess the accuracy of computed tomography in diagnosing acute appendicitis with a special reference to radiologist experience. Material and Methods: Data were collected prospectively in our randomized controlled trial comparing surgery and antibiotic treatment for uncomplicated acute appendicitis (APPAC trial, NCT01022567). We evaluated 1065 patients who underwent computed tomography for suspected appendicitis. The on-call radiologist preoperatively analyzed these computed tomography images. In this study, the radiologists were divided into experienced (consultants) and inexperienced (residents) ones, and the comparison of interpretations was made between these two radiologist groups. Results: Out of the 1065 patients, 714 had acute appendicitis and 351 had other or no diagnosis on computed tomography. There were 700 true-positive, 327 true-negative, 14 false-positive, and 24 false-negative cases. The sensitivity and the specificity of computed tomography were 96.7% (95% confidence interval, 95.1–97.8) and 95.9% (95% confidence interval, 93.2–97.5), respectively. The rate of false computed tomography diagnosis was 4.2% for experienced consultant radiologists and 2.2% for inexperienced resident radiologists (p = 0.071). Thus, the experience of the radiologist had no effect on the accuracy of computed tomography diagnosis. Conclusion: The accuracy of computed tomography in diagnosing acute appendicitis was high. The experience of the radiologist did not improve the diagnostic accuracy. The results emphasize the role of computed tomography as an accurate modality in daily routine diagnostics for acute appendicitis in all clinical emergency settings.

Economic evaluation of antibiotic therapy versus appendicectomy for the treatment of uncomplicated acute appendicitis from the APPAC randomized clinical trial. Br J Surg 2017; 104:1355-1361. [PMID: 28677879 DOI: 10.1002/bjs.10575] [Citation(s) in RCA: 50] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2016] [Revised: 02/14/2017] [Accepted: 03/28/2017] [Indexed: 12/20/2022]
Abstract
BACKGROUND An increasing amount of evidence supports antibiotic therapy for treating uncomplicated acute appendicitis. The objective of this study was to compare the costs of antibiotics alone versus appendicectomy in treating uncomplicated acute appendicitis within the randomized controlled APPAC (APPendicitis ACuta) trial. METHODS The APPAC multicentre, non-inferiority RCT was conducted on patients with CT-confirmed uncomplicated acute appendicitis. Patients were assigned randomly to appendicectomy or antibiotic treatment. All costs were recorded, whether generated by the initial visit and subsequent treatment or possible recurrent appendicitis during the 1-year follow-up. The cost estimates were based on cost levels for the year 2012. RESULTS Some 273 patients were assigned to the appendicectomy group and 257 to antibiotic treatment. Most patients randomized to antibiotic treatment did not require appendicectomy during the 1-year follow-up. In the operative group, overall societal costs (€5989·2, 95 per cent c.i. 5787·3 to 6191·1) were 1·6 times higher (€2244·8, 1940·5 to 2549·1) than those in the antibiotic group (€3744·4, 3514·6 to 3974·2). In both groups, productivity losses represented a slightly higher proportion of overall societal costs than all treatment costs together, with diagnostics and medicines having a minor role. Those in the operative group were prescribed significantly more sick leave than those in the antibiotic group (mean(s.d.) 17·0(8·3) (95 per cent c.i. 16·0 to 18·0) versus 9·2(6·9) (8·3 to 10·0) days respectively; P < 0·001). When the age and sex of the patient as well as the hospital were controlled for simultaneously, the operative treatment generated significantly more costs in all models. CONCLUSION Patients receiving antibiotic therapy for uncomplicated appendicitis incurred lower costs than those who had surgery.

Abstract
Oulu University Hospital has a Web-based multimedia medical record in use. One key element in the creation of regional e-health networks is an electronic referral letter and discharge letter service. In Oulu an XML messaging system is used for an integral part of the medical record. The service has now been extended to primary care centres and hospitals in the Oulu region. Using a secure Web link, primary care physicians have direct remote access to the original hospital's electronic patient record, including medical images and laboratory results. According to the users, e-referral saves time and improves the quality of documentation. On the other hand, workflow development is still immature. Our experience suggests that the implementation of e-referrals is a process which requires careful handling, in relation to the technology as well as organizational changes and communication.

Abstract
Chemical inflammation was induced subcutaneously in 10 rats using carrageenan mucopolysaccharide. Dual spin echo (SE) imaging of inflammatory loci was performed employing a 0.35 tesla resistive magnet. In addition, gadolinium-DTPA was administrated intravenously into 5 rats to evaluate the potential benefits of paramagnetic contrast medium for the detection and characterization of inflammatory loci. T2 weighted SE images demonstrated the edematous lesions as zones of high intensity. This was attributed to the increased relaxation times of lesions when compared to the adjacent soft tissue. The inflammation was also delineated on T1 weighted SE images, but only after injection of paramagnetic Gd-DTPA. Carrageenan mucopolysaccharide-in-duced lesions provide a useful experimental model for in vivo evaluation of soft tissue inflammation using magnetic resonance imaging. No special benefit of paramagnetic contrast enhancement was demonstrated in this model of local edema.

Abstract
Two nitroxide spin labels (NSL) were compared for in vitro relaxivity and in normal rats for efficiency of urographic enhancement. One of the NSL, PCA, a pyrrolidinyl agent, was ionic and one, NAT, was a non-ionic pyrrolidinyl NSL with multiple hydroxyl substituents for water solubility. Using both NSLs the renal medulla and papilla were noted to show greater contrast enhancement than the cortex, with a maximum enhancing effect between 5 and 15 minutes. Using doses of 1.0 and 2.5 mmol/kg, more than 100 per cent increases in spin echo intensities above the baseline were observed. The lowest tested dose of 0.1 mmol/kg showed an easily detectable enhancing effect for NAT. The good contrast enhancing properties of NAT, considered together with its better acute tolerance, justifies further investigation of this non-ionic compound.

Abstract
Intramuscular hemorrhage was induced by injecting autologous blood into the paraspinal muscle of 8 rabbits. In order to evaluate the time-dependent changes of hemorrhage observed on MRI, the animals were imaged at different stages of blood resolution at 0.02 tesla (T), and control examined with ultrasound using a 7.5 MHz linear transducer. Six inversion recovery sequences (TR= 1000 ms. TE = 30 ms, and TI = 18, 48, 148, 201, 302, and 398 ms) were used for the invivo calculation of T1 relaxation times. IR 1000 (398)/30 imaging was performed before and after the Gd-DOTA administration. The hemorrhage was evident on MR images throughout the study, especially on the T2 weighted (SE 1000/100) images. MRI showed the healing lesion longer than ultrasound. The T1 relaxation time increased during the time of resolution. Lesions on days 4 to 7 enhanced in intensity after the injection of Gd-DOTA.

Abstract
Background and Aims: The purpose of this study was to evaluate the efficacy of high-resolution axillary ultrasound (AU) in detecting the rate of recurrence after anegative sentinel node (SN) biopsy in patients with breast cancer and without additional axillary dissection. Materials and Methods: The operating oncologic surgeon performed 196 consequent sentinel node biopsies during surgery of breast cancer. The sentinel nodes were identified by using preoperative lymphoscintigraphy, intraoperative gamma probe and Patent Blue® dye. A routine postoperative follow-up of the patients were performed every 3rd month including clinical examinations, blood chemistry and mammography. After 31 months (range 14–49 months), a high-resolution AU was performed for 107 patients with a negative sentinel node during surgery and without axillary dissection, to visualize any abnormal lymph nodes in the axilla. If necessary, large core biopsies were undertaken to obtain histology of abnormal axillary nodes. Results: The SNs were visualized during preoperative lymphoscintigraphy in 167/196 (85%) and found during the surgery in 163/167 (98%) of patients. The mean number of removed SN were 1.7 ±0.8. The SN metastasis were found in 29% (56/196) of patients. During the follow-up, abnormal nodes were identified during AU in only 4/107 patients. Core biopsies confirmed benign histology in three patients and one case of lymphoma was detected. Conclusions: There were no axillary recurrences of breast cancer after a negative SN biopsy during the 2.6 year follow-up. Axillary ultrasound is a useful tool in the quality control of patients with negative SN biopsy and without diagnostic axillary dissection.

Abstract
Background Major bleeding is rare but among the most serious complications of laparoscopic surgery. Still very little is known on bleeding complications and related blood component use in laparoscopic cholecystectomy (LC). The aim of this study is to compare bleeding complications, transfusion rates and related costs between LC and open cholecystectomy (OC). Methods Data concerning LCs and OCs and related blood component use between 2002 and 2007 were collected from existing computerized medical records (Finnish Red Cross Register) of ten Finnish hospital districts. Results Register data included 17175 LCs and 4942 OCs. In the LC group, 1.3 % of the patients received red blood cell (RBC) transfusion compared to 13 % of the patients in the OC group (p < 0.001). Similarly, the proportions of patients with platelet (0.1 % vs. 1.2 %, p < 0.001) and fresh frozen plasma (FFP) products (0.5 % vs. 5.8 %) transfusions were respectively higher in the OC group than in the LC group. The mean transfused dose of RBCs, PTLs and FFP product Octaplas® or the mean cost of the transfused blood components did not differ significantly between the LC and OC groups. Conclusions Laparoscopic cholecystectomy was associated with lower transfusion rates of blood components compared to open surgery. The severity of bleeding complications may not differ substantially between LC and OC.

Abstract
BACKGROUND AND AIMS Aging with comorbidities, obesity, and rapid recovery from operation may increase the need for laparoscopic cholecystectomy, but long-term use of statins may be associated with a decreased risk of gallstones. This population-based cohort study presents the changing rate and causative factors of laparoscopic cholecystectomy in Finland during the era of statin use. MATERIALS AND METHODS Age structure of the population, changes in body mass index and diabetes, and the number of all cholecystectomies in 1995-2009 were retrieved from the registers of National Institute for Health and Welfare. Additionally, these results were supplemented by a population-based retrospective cohort (1581 laparoscopic cholecystectomy) in one community-based hospital area. The risk factors for laparoscopic cholecystectomy, use of statins, and surgical outcome were analyzed. RESULTS During the 15 years, 123,794 cholecystectomies were performed in Finland, of which 94,740 (76.5%) were performed using laparoscopic technique. The median rate of laparoscopic cholecystectomy varied between 110 and 140 operations per 100,000 inhabitants. In 1995-2009, the annual number of cholecystectomies decreased from 8600 to 7500, the number of laparoscopic cholecystectomies increased by 10%, and the number of open cholecystectomies declined by 60%. In a cohort of 1581 laparoscopic cholecystectomies, the proportion of elderly (>65 years of age), obese (body mass index > 30 kg/m(2)), and diabetic patients increased from 17% to 28%, 9% to 34%, and 4% to 8%, respectively. Use of statins increased more than fourfold during the 15 years. CONCLUSIONS The rates of all cholecystectomies decreased despite marked increase in laparoscopic cholecystectomies performed. The increase in risk factors for gallstones in Finland implied more marked increase in laparoscopic cholecystectomies. The possible role of statins on gallstone disease is discussed.

Abstract
AIM Our aim was to evaluate the incidence and type of severe complications in adult primary and incisional ventral hernia surgery reported to the National Patient Insurance Centre in Finland during 2003-2010. MATERIAL AND METHODS The Finnish National Patient Insurance Centre covers the whole country and handles financial compensation for patients' injuries without proof of malpractice. All the claims concerning ventral hernioplasties in the Centre between the years 2003 and 2010 were retrospectively analyzed. The annual numbers of primary and incisional ventral hernioplasties in Finland were obtained from the National Hospital Discharge Register. RESULTS During the study years, 25,738 ventral hernia operations were performed and 127 claims from the whole country were reported to the Patient Insurance Centre. Overall rate of claims was 4.9/1000 hernia procedures. For primary hernias, 16,243 ventral hernioplasties (817 laparoscopic, 15,426 open) were performed and 41 complications were reported. The most common complication was infection (n = 28, 68%) followed by pain and hernia recurrence (n = 6, 15% in both), large hematoma (7%), bowel lesion (5%), urological injuries (2%), or severe bleeding (2%). In incisional hernioplasties, the rate of claims was 9.1/1000 operations (9495 operations, 86 claims). The most common complication reported was infection (n = 42, 49%) followed by hernia recurrence in 25 cases (29%) and bowel lesion in 24 cases (28%). Major complications (n = 15, 17%) consisted mainly of bowel lesions in laparoscopic operations. There was significantly more claims after laparoscopic than open hernioplasties (p = 0.001). CONCLUSIONS The claims for financial compensation for injuries related to primary and incisional hernioplasties are quite uncommon. Major complications, though comparatively rare, are significantly more common after laparoscopic operations.

Abstract
BACKGROUND Non-specific abdominal pain (NSAP) and acute appendicitis (AA) are the two most frequent diagnoses of acute abdomen in the emergency wards. The long-term morbidity, mortality and quality of life of the patients with NSAP compared to AA are unknown. METHODS The study group consisted of 186 patients with acute NSAP compared to 147 patients with AA initially treated during 1985-1986. Medical history, social background, quality of life and abdominal symptoms were assessed with standardized questionnaires in both groups during 2006-2009. The patients who continued to have abdominal symptoms were invited to a check-up visit. RESULTS During 1985-6, the NSAP group had more previous abdominal symptoms and operations than the AA group. Some 29% of patients with NSAP and 11% of patients with AA had still abdominal symptoms at long-term check-up (p < 0.0001). Chronic abdominal pain (38 vs 17) and peptic ulcer disease (18 vs 2) occurred more often in the NSAP group than in the controls, respectively (p = 0.001). After five years of follow-up, 11 patients in the NSAP group and 6 patients in the AA group had died (ns). During the twenty years of follow-up, mortality was higher (46/22, 25/15%) in the patients with NSAP than in controls (p = 0.013). Ischaemic heart disease was the leading cause of death in both groups (18 NSAP vs 5 AA, p = 0.017). The quality of life scores were comparable in both study groups. CONCLUSION Over 70% of NSAP- and almost 90% of AA-patients were free of symptoms after 20 years of follow-up. Mortality was higher and various alimentary track diseases were more frequent in patients with NSAP than in AA.

Abstract
Athletic pubalgia (sportsman's hernia) is often repaired by surgery. The presence of pubic bone marrow edema (BME) in magnetic resonance imaging (MRI) may effect on the outcome of surgery. Surgical treatment of 30 patients with athletic pubalgia was performed by placement of totally extraperitoneal endoscopic mesh behind the painful groin area. The presence of pre-operative BME was graded from 0 to 3 using MRI and correlated to post-operative pain scores and recovery to sports activity 2 years after operation. The operated athletes participated in our previous prospective randomized study. The athletes with (n = 21) or without (n = 9) pubic BME had similar patients' characteristics and pain scores before surgery. Periostic and intraosseous edema at symphysis pubis was related to increase of post-operative pain scores only at 3 months after surgery (P = 0.03) but not to long-term recovery. Two years after surgery, three athletes in the BME group and three in the normal MRI group needed occasionally pain medication for chronic groin pain, and 87% were playing at the same level as before surgery. This study indicates that the presence of pubic BME had no remarkable long-term effect on recovery from endoscopic surgical treatment of athletic pubalgia.

Abstract
Background
Chronic pain may be a long-term problem related to mesh fixation and operative trauma after Lichtenstein hernioplasty. The aim of this study was to compare the feasibility and safety of tissue cyanoacrylate glue versus absorbable sutures for mesh fixation in Lichtenstein hernioplasty.
Methods
Lichtenstein hernioplasty was performed under local anaesthesia as a day-case operation in one of three hospitals. The patients were randomized to receive either absorbable polyglycolic acid 3/0 sutures (Dexon®; 151 hernias) or 1 ml butyl-2-cyanoacrylate tissue glue (Glubran®; 151 hernias) for fixation of lightweight mesh (Optilene®). Wound complications, pain, discomfort and recurrence were identified at 1 and 7 days, 1 month and 1 year after surgery.
Results
A total of 302 patients were included in the study. The mean(s.d.) duration of operation was 34(12) min in the glue group and 36(13) min in the suture group (P = 0·113). The need for analgesics was similar during the first 24 h after surgery. Five wound infections (3·4 per cent) were detected in the glue group and two (1·4 per cent) in the suture group (P = 0·448). The recurrence rate at 1 year was 1·4 per cent in each group (P = 1·000). The rates of foreign body sensation, acute and chronic pain were similar in the two groups. Logistic regression analysis showed that the type of mesh fixation did not predict chronic pain 1 year after surgery.
Conclusion
Mesh fixation without sutures in Lichtenstein hernioplasty was feasible without compromising postoperative outcome. Registration number: NCT00659542 (http://www.clinicaltrials.gov).

Abstract
BACKGROUND Chronic pain may be a long-term problem related to operative trauma and mesh material in Lichtenstein hernioplasty. STUDY DESIGN Inguinal hernioplasty was performed under local anesthesia in 228 patients (232 hernias) in day-case surgery by the same surgeon and exactly by the same surgical technique. The patients were randomized to receive either a partly absorbable polypropylene-polyglactin mesh (Vypro II(R) 50 g/m(2), 79 hernias), a lightweight polypropylene mesh (Premilene Mesh LP(R) 55 g/m(2), 75 hernias) or a conventional densely woven polypropylene mesh (Premilene(R) 82 g/m(2), 78 hernias). Pain, patients discomfort and recurrences of hernias were carefully followed at days 1, 7, 1 month, 1 and 2 years after surgery. RESULTS The duration of operation (29-33 min) and the amount of local anesthetic (55-57 ml) were similar in the three groups. Two wound infections and four hematomas were detected with no difference between the meshes. Immediate pain reaction up to 1 month was statistically equal among the three meshes. After 2 years of follow-up, there were five recurrences (two in the Vypro group, one in the Premilene LP and two in the Premilene). A feeling of a foreign body, sensation of pain and patient's discomfort were similar with all meshes. CONCLUSION There was no difference of pain and quality of life among a conventional polypropylene mesh, lightweight mesh or partly absorbable mesh in 2 years of follow-up, when the same surgeon operated on all patients with exactly the same technique.

Abstract
BACKGROUND This study aimed to assess the efficacy of diagnostic laparoscopy and open exploration of trigger points (scar revision and neurectomy) in the treatment of intractable chronic abdominal wall pain. METHODS This prospective nonrandomized study enrolled 24 patients (21 women) with an average age of 59 +/- 11 years. Abdominal wall pain was diagnosed by excluding other causes of pain and using multiple injections of bupivacain. The patients' demographic data and long-term postoperative course (37 +/- 13 months) were carefully recorded. RESULTS Using laparoscopy, intraabdominal adhesions close to trigger points were found and lysed in 15 patients (63%). Next, a subcutaneous nerve resection was performed. After 1 month, 33% of the patients were completely pain free, and 42% reported alleviation of pain. After 3 years, chronic abdominal pain was totally healed in 25%, diminished in 50%, and unchanged or increased in 25% of the patients. A total of 23 patients (96%) reported that surgery was beneficial for their intractable pain. CONCLUSIONS Laparoscopy used in open exploration is beneficial for 75% of carefully selected patients with chronic abdominal wall pain.

Abstract
Osteitis pubis is characterized by pain, inflammation, and sclerosis in the pubic symphysis. It is often a self-limiting disease in athletes, but persistent pain may occasionally need surgery. Video-assisted placement of extraperitoneal retropubic synthetic mesh to support the damaged area may hasten the healing of this injury. During 1997 - 2002 five elite level male athletes with chronic groin pain associated with osteitis pubis were operated. The diagnosis was based on clinical findings, x-ray, magnetic resonance imaging (MRI), and isotope bone scanning. A 10 x 15 cm polypropylene mesh was placed into preperitoneal retropubic space using video-assisted technique. The pain and return to sport were asked at 1, 6, and 12 months after surgery. Preoperative technetium bone scan revealed an enhanced isotope uptake of pubic bone in each patient. T2-weighted MRI (n = 3) indicated bone marrow edema, which was decreased postoperatively on repeated MRI scans. Periosteal edema and irritation were also seen at operation. No complications were associated with the insertion of mesh. All 5 athletes returned to their sport activities between one to two months after surgery. After one year, no tenderness or pain was observed in the pubic bone. When conservative treatment fails, the placement of retropubic mesh is safe and a mini-invasive method to hasten the rehabilitation of osteitis pubis in selected cases. The postoperative recovery was uneventful, and the patients returned rapidly to their sporting activities.

Abstract
OBJECTS Surgical repair of very large ventral hernias has become feasible after the introduction of synthetic meshes and developments in intensive-care treatment. In addition to the operative challenges, postoperative disorders in the cardiovascular system, tissue oxygenation, increased intra-abdominal pressure, and pulmonary embolism expose the patient to severe risks. METHODS From 1997-2002 we operated on ten patients with giant ventral incisional or umbilical hernia (mean defect size 240 cm(2)) by using retromuscular polypropylene mesh. All patients were morbidly obese [mean Body Mass Index (BMI) 39+/-7.2 kg/m(2)]. Four of the operations were emergencies because of an acute intestinal occlusion, bowel gangrene, and skin complications. The patients were reinvestigated after the mean follow-up of 2.5 years to find out the frequency of recurrence and degree of disability. RESULTS AND CONCLUSION There was no intraoperative mortality, but one patient died at home after 5 weeks because of myocardial infarct and prolonged wound infection. She had mild stable coronary heart disease preoperatively. Although minor wound complications were observed in three patients, there was no need to remove the meshes. One small recurrent hernia was observed in the follow-up, but it was too small to be repaired. The quality of life after surgery was good for all patients, and they were satisfied with the operation. Retromuscular mesh hernioplasty associated with careful patient monitoring in intensive care is safe and feasible in the selected patients with massive ventral hernia.

Abstract
BACKGROUND Cytokines and leukocyte adhesion molecules are activated and found in increased concentrations in bacterial infection. The purpose of this study was to investigate whether some of these new serum markers could be feasible as a single on-admission test to predict acute appendicitis (AA). METHODS In an open prospective study the diagnostic potentials of two cytokine measurements (interleukin-6 and interleukin-8), soluble leukocyte adhesion molecule (CD44), C-reactive protein (CRP) and white blood cell (WBC) count were compared in 80 consecutive patients who had undergone surgery for suspected AA. The diagnostic performance of each parameter was tested by using receiver operating characteristic (ROC) curves. RESULTS Phlegmonous AA was found in 34%, gangrenous AA in 40% and perforated AA in 5% of the patients. The proportion of negative explorations was 21%. Preoperative serum concentrations of IL-6 and CRP were elevated only in gangrenous and perforated AA. The concentrations of IL-8 and CD44 remained unchanged in AA. The sensitivity (84%), specificity (79%) and diagnostic accuracy (82%) of IL-6 were higher than the values for CRP, WBC, IL-8 and CD44 in predicting AA. CONCLUSION ROC analysis confirmed that IL-6 showed the best trend in the diagnosis of AA. However, the diagnosis of AA was not greatly improved by any of the new serum markers as single on-admission tests.

Abstract
BACKGROUND In Scandinavian countries the use of local anaesthesia combined with fast patient's discharge is still uncommon in inguinal herniorraphy. AIMS To report the feasibility, safety, costs and long-term outcome in terms of pain and recurrence after 101 open inguinal herniorraphies operated under local anaesthesia as rapid outpatient procedure. METHODS All patients were selected and operated using Lichtenstein polypropylene mesh herniorraphy by the same senior surgeon and one nurse. The incidence of pain and recurrences were asked by questionnaire after the mean follow-up of 2 years. RESULTS The rate of clinically important wound hematomas (n = 3) and infections (n = 1) were low as well as the number of recurrences (n = 1). Although 23 % of the patients felt later some pain sensations in the inguinal region, only 2 patients needed occasionally pain-relieving drugs. Over 90 per cent of the patients were very satisfied with the operation. CONCLUSION Lichtenstein inguinal hernioplasty under local infiltration anaesthesia is rapid, well-tolerated, simple and inexpensive operation, which gives excellent results.

Abstract
A nationwide mammographic screening of women ages 50 to 59 years commenced in Finland in January 1987. We studied the demands of screening on surgical inpatient services by comparing the treatment strategy, volume of breast biopsies, and hospital stay before and after implementation of mass screening of women age 50 to 59. Approximately 20 patients per 100,000 inhabitants were referred annually from mass screening for surgical biopsies, in half of which cancer was detected. In 1985 through 1986 (before screening) we operated on 134 patients suspected of having breast cancer. After the first (in 1990) and the second (in 1995) round of mammographic screening we operated on 161 patients in 2 years suspected of having breast cancer. Concurrently 25 of 92 cancers (27%) were found only because of the screening. Before the screening period clinical symptoms and palpable tumors were cause for referral to surgery in 84 per cent of the cases and abnormal mammography in only 16 per cent. During screening these ratios were 34 and 61 per cent, respectively. The number of T(is)-1 cancers (<2 cm) increased from 44 per cent before screening to 70 per cent during screening. In contrast the number of T2 cancers (2-4 cm) decreased from 40 to 20 per cent. The mammographic screening did not increase the hospital stay of patients. We conclude that the mammographic screening program of all women age 50 to 59 years increased the number of surgical biopsies in our hospital by only 30 per cent. Breast cancer was found at an earlier stage during screening. More than one-fourth of breast cancers are currently found through the mass screening program in Finland.

Abstract
Pancreatic infection is the main indication for surgery and the principal determinant of prognosis in acute necrotizing pancreatitis. Previous studies on the effects of antibiotics have not, however, uniformly demonstrated any reduction in the need for surgery or any decrease in mortality among these patients, although the incidence of pancreatic infections was significantly reduced. This single-center randomized study was designed to compare early vs. delayed imipenem treatment for acute necrotizing pancreatitis. Ninety patients with acute necrotizing pancreatitis (C-reactive protein > 150 mg/L, necrosis on CT) were randomized within 48 hours either to a group receiving imipenem (1.0 g plus cilastatin intravenously 3 times a day) or a control group. Not included were those who had been started on antibiotics at the referring clinic, those who were taken directly to the intensive care unit for multiorgan failure, and those who refused antibiotics or might have had adverse reactions. Thirty-two patients were excluded because they were over 70 years of age (not potentionally operable) or for any study violation. There were 25 patients in the imipenem group and 33 patients in the control group. The main end point was the indication for necrosectomy due to infection (i.e., after the initial increase and decrease, there was a second continuous increase in temperature, white blood cell count [> 30%] and C-reactive protein [> 30%], with other infections ruled out, or bacteria were found on Gram stain of the pancreatic fine-needle aspirate). In the control group, imipenem was started when the operative indication was fulfilled. Conservative treatment was continued for at least 5 days before necrosectomy. The study groups did not differ from each other with regard to sex distribution, patient age, etiology, C-reactive protein concentration, and extent of pancreatic necrosis on CT. Two (8%) of 25 patients in the imipenem group compared to 14 (42%) of 33 in the control group fulfilled the operative indications (P = 0.003). Nine patients in the control group responded to delayed antibiotics but five had to undergo surgery. Of those receiving antibiotics, 2 (8%) of 25 in the early antibiotic (imipenem) group needed surgery compared to 5 (36%) of 14 in the delayed antibiotic (control) group (P = 0.04). Two (8%) of 25 patients in the imipenem group and 5 (15%) of 13 patients in the control group died (P = NS [no significant difference]). Seven (28%) of 25 in the imipenem group and 25 (76%) of 33 in the control group had major organ complications (P = 0.0003). Based on the preceding criteria, early imipenem-cilastatin therapy appears to significantly reduce the need for surgery and the overall number of major organ complications in acute necrotizing pancreatitis, and reduces by half the mortality rate; this is not, however, statistically significant in a series of this size.

Abstract
The sensitivity and specificity of ultrasonography in detection of free intraperitoneal fluid is over 90 %. The lowest detectable volume of free fluid in humans is unknown. The distribution of intraperitoneal fluid was studied in 86 patients by transabdominal US in group A (n = 21, 10 ml of fluid), in group B (n = 15, 50 ml of fluid) and group C (n = 50, splenic trauma). Ultrasound detected fluid in 15 of 21 patients in group A, and in all patients in groups B and C. In group A 10 ml of fluid was found in 71 % of cases behind the bladder, and in only 5-14 % of cases in the upper abdomen. In group B 50 ml of fluid was found in all patients in the lower pelvis, but in only 20 % in Morison's pouch and in 7 % around the spleen. In group C 200-4500 ml of fluid was detected by US in 72 % of patients in the perisplenic space, in 60 % in Morison's pouch and in 42 % in the retrovesical space. Small volumes of free intraperitoneal fluid (10-50 ml) can be detected with current US scanners, but only near the site of injury. These results support the role of US as a primary imaging modality in abdominal trauma.

Abstract
To investigate the regenerative potential of human disc tissue, the disc samples were obtained during surgery from 24 adult patients with first lumbar prolapses and from 14 patients with recurrent lumbar prolapses. Preoperative magnetic resonance imaging (MRI) confirmed prolapse and disc degeneration in all cases. The proliferation activity of the sampled connective tissue cells was studied with the immunohistochemical expression of Ki-67(MIB-1) antigen. The antigen was positive in 6 of 24 (25%) specimens from first prolapse and in none of the 14 specimens from the recurrent prolapse. The amount of proliferative cells did not correlate to the degree of disc degeneration in MRI. Our results indicate that connective tissue cells in adult degenerative disc may show proliferation activity after the first herniation and thus regenerative potential. The enhanced matrix proliferation may not be a significant reason for recurrent prolapses because none of the recurrent disc specimen showed proliferation activity.

Abstract
OBJECTIVE To compare the distribution of interstitial collagens (type I and III) and basement membrane collagen (type IV) in cancerous and normal colon. DESIGN Retrospective study. SETTING University hospital, Finland. SUBJECTS 13 patients with colorectal cancer of different stages and grades. MAIN OUTCOME MEASURES Indirect immunofluorescence labelling for type I, III, and IV collagens of fresh frozen tissue samples, both normal and cancerous, cut into serial sections 6 microm thick. RESULTS In normal mucosa, the epithelial basement membrane showed an intense immunoreaction for type IV collagen. Type I and III collagens were localised to the interstitial stroma underlying it. The membrane in cancer samples was characterised by discontinuities and thinning as estimated by immunolabelling for type IV collagen. Furthermore, immediately adjacent to the membrane type I and III collagen positivity was fragmented. The cancerous stroma showed a strong positive immunosignal for type I and III collagens. CONCLUSION Both the epithelial basement membrane and the collagenous matrix immediately beneath it are degraded in malignant tissue. This may suggest the simultaneous activation of several degradative enzymes (as type I and III collagens are at least in part degraded by different enzymes from type IV collagen) or alterations in the expression of collagen subtypes in normal compared with malignant tissue.

Abstract
BACKGROUND Postoperative hyperamylasemia and even acute pancreatitis are associated with coronary artery bypass grafting (CABG). The mechanism of hyperamylasemia and pancreatic acinar cell damage was studied in 20 patients undergoing CABG. METHODS Serial blood and urine samples at eight time points before, during, and 24 hours after the CABG were collected. Salivary and pancreatic isoamylases, the fractional clearance of isoamylases (i.e., relative to creatinine clearance), pancreatic phospholipase A2 (a specific serum marker of pancreatic acinar cell injury), and cystatin C (a sensitive marker of glomerular filtration rate) were measured. RESULTS Mild serum hyperamylasemia (300 to 1000 units/L) was found in 11 of 20 (55%) and severe (> 1000 units/L) in 6 of 20 (30%) patients with no signs of clinical acute pancreatitis. Hyperamylasemia occurred from 6 to 24 hours after the CABG and was mainly caused by pancreatic isoamylase. Serum pancreatic phospholipase A2 concentration remained unchanged, which excludes acinar cell damage. Although renal glomerular filtration was normal during CABG as measured by serum cystatin C and creatinine clearance, the fractional clearance of isoamylases decreased. CONCLUSIONS The decreased rate of excretion into urine, rather than pancreatic cellular damage, is the major source of hyperamylasemia after CABG.

Abstract
We report a case of infectious thrombosis of the superior mesenteric vein (pylephlebitis) that was suspected preoperatively with computed tomography and confirmed at intraoperative ultrasonography as confined to the extrahepatic portal vein and superior mesenteric vein. Intraoperative ultrasonography revealed intraluminal echogenic thrombus material in the dilated superior mesenteric and extrahepatic portal veins, slightly dilated open splenic vein, and numerous venous collaterals in the hepatoduodenal ligament. When preoperative imaging studies are inconclusive, intraoperative sonography can confirm the correct diagnosis of pylephlebitis and may give valuable information about the extent of the thrombosis.

Abstract
OBJECTIVE Audit of the protocol for surgical treatment of patients with acute severe and necrotising pancreatitis (ANP). DESIGN Prospective open study. SETTINGS University hospital, Finland. PATIENTS 33 patients treated for severe (Ranson score 3 or more) and necrotising (as judged on computed tomograms (CT)) pancreatitis between 1992-1993. PROTOCOL Indications for antibiotic treatment (n = 25 patients) were: fulminant multiorgan disease; recurrent continual parallel increase in temperature, white cell count (WCC) and C-reactive protein concentration; or the presence of bacteria on Gram stain of a percutaneous fine needle aspiration smear of necrosis. Three of the 25 responded to antibiotics. They and eight others with ANP but without these indications were treated conservatively. Twenty-two patients underwent repeated necrosectomy by laparostomy. MAIN OUTCOME MEASURES Diagnosis of pancreatic infection, morbidity and mortality RESULTS Of the 22 patients operated on 17 had contaminated necrosis at operation, and this had been predicted by the increasing inflammatory variable and the presence of bacteria in the Gram stain. Five patients operated on died (23%), four of the five having been operated on for fulminant multiorgan disease (80%). Recurrent sepsis developed in five patients, pancreatic fistulas in two, and there were no pseudocysts. Gastrointestinal fistulas developed in 12 patients, but not after we had changed the technique of wound packing. All 11 patients treated conservatively survived. CONCLUSION A third of patients with ANP can be selected for safe non-operative treatment. Infected ANP can be treated by repeated necrosectomy by laparostomy with low mortality (6%). Early fulminant multiorgan disease should not be treated with laparostomy.

Abstract
BACKGROUND Preoperative measurement of body inflammatory agents reduces unnecessary appendectomies by up to 30 percent. A decline in the formation of blood leukocytes and C-reactive protein with aging may hinder the correct diagnosis of appendicitis. STUDY DESIGN White cell count and C-reactive protein were determined before appendectomy in 600 patients aged 0 to 5 years, 6 to 19 years, 20 to 39 years, 40 to 59 years, 60 to 79 years, and older than 80 years. Their records were analyzed. The sensitivity, specificity, diagnostic accuracy, and receiver-operating characteristic curves for C-reactive protein and white cell count to predict appendicitis were calculated separately for each age group. RESULTS The rates of negative explorations and perforations were highest at both extremes of age. In uncomplicated appendicitis, the diagnostic potential of white cell count was better than C-reactive protein in all age groups except infants. The C-reactive protein was elevated similarly throughout human life, but only in those with perforated appendicitis. The receiver-operating characteristic curves confirmed that the performance of white cell count was better than C-reactive protein in the correct diagnosis in every age group except infants and octogenarians. CONCLUSIONS The leukocyte response declines in 0- to 5-year-old children with appendicitis, but the C-reactive protein response is well preserved in all other age groups.

Abstract
The prevalence of lumbar disc degeneration in subjects suffering from low-back pain (n = 207; age range 10-49 years) and in age-matched asymptomatic controls (n = 216) was investigated by magnetic resonance imaging. The percentage of subjects with degenerated discs increased with age; starting from the age of 15 years, this increase was more rapid in subjects with low-back pain. Concurrently, the number of degenerated discs was higher in the pain group than in controls. Lumbar disc degeneration manifests earlier and in a greater percentage of subjects with low-back pain than in asymptomatic controls.

Abstract
The mechanism of postoperative hyperamylasaemia was studied in 48 patients undergoing coronary artery bypass grafting (CABG). Mild hyperamylasaemia developed in 87% of the patients, and in 10% the serum amylase activity was > 1000 U/l. Serial measurements of serum salivary (S-) and pancreatic (P-) isoamylases indicated that hyperamylasaemia was highest 24 hours after CABG and consisted mainly of P-amylase component. Serum creatinine, creatinine clearance and urinary albumin concentration remained normal after CABG, excluding severe renal damage. The fractional clearance (i.e. relative to creatinine clearance) of P-amylase decreased more than of S-amylase (from 3.6 to 0.9% vs 1.3 to 0.8%). Decreased rate of excretion into urine, rather than pancreatic cellular damage, is the main source of hyperamylasaemia after CABG.

Abstract
Antioxidants may reduce pancreatic cellular injury after coronary artery bypass grafting (CABG) Twenty patients (Group A) received vitamin E (600 mg/ day) for 28 days and vitamin C (2 g/day) and allopurinol (600 mg/day) 2 days before and 1 day after CABG. Seventeen patients (Group C) received all drugs for 3 days, and 25 (Group B) and 19 (Group D) patients served as corresponding controls. The pre- and postoperative pancreatic isoamylase (P-amylase), creatinine, and antioxidant concentrations were measured. Serum hyperamylasemia was highest on the first postoperative day and occurred in 73% of the patients. After surgery serum P-amylase increased in all study groups and urine P-amylase decreased. Postoperative serum hyperamylasemia, whether primarily renal or pancreatic, cannot be decreased by pretreatment with allopurinol, vitamin C, and vitamin E.

Abstract
The symptoms of right-sided renal colic mimic sometimes acute appendicitis. A prospective comparative study of 188 patients with ureteral stone and 188 patients with acute appendicitis was performed to evaluate the features of differential diagnosis. Appendicitis caused more often nausea (81 vs 11%), fever and localized pain in the McBurney (97 vs 59%) than renal colic. The patients with ureteral stone had tenderness in 16% in the right lower quadrant. The mean values of C-reactive protein (41 mg/l) and blood leukocytes (14 x 10(9)/l) were elevated in appendicitis, but not in renal colic (14 mg/l and 10 x 10(9)/ l). Urinanalysis revealed red cells in 92% of ureteral stones compared with 26% in appendicitis. Only one of 188 patients with appendicitis was first misdiagnosed to have renal colic. A mistake of appendicitis for ureteral stone is clinically rare occurring only once or twice per year in the hospital where 700-800 emergency appendectomies are annually performed.

Acute pancreatitis in patients over 80 years. THE EUROPEAN JOURNAL OF SURGERY = ACTA CHIRURGICA 1996; 162:471-5. [PMID: 8817224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To evaluate the occurrence, aetiology and outcome of acute pancreatitis (AP) in patients over 80 years of age, compared with those between 61 and 79 years old. DESIGN Retrospective analysis. SETTING University hospital, Finland. SUBJECTS Subgroups of 22 patients 80 years old or over and 139 patients 61-79 years old out of 1058 episodes of AP between 1982 and 1990. MAIN OUTCOME MEASURES Mortality, morbidity, and hospital stay. RESULTS The percentage of patients aged 80 or more varied from 0 in 1982 to 3% in 1990; 13 (59%) were women compared with 47 (34%) in the 61-79 year old group (p = 0.03). AP in the older group was more likely to be necrotising 9/22 (41%) compared with 23/139 (17%), p = 0.02) and to have been caused by biliary disease 15/22 (68%) compared with 54/139 (39%), (p = 0.01). The overall mortality was 9/22 (41%) in the 80 years and over group and 24/139 (17%) in patients aged 61-79 years (p = 0.02). All 9 patients in their eighties with necrotising pancreatitis died. Neither the mode of treatment nor the Glasgow prognostic scoring had any relation to mortality in the older group. CONCLUSIONS AP in patients of 80 or more is a serious disease with a high mortality irrespective of standard treatment.

Abstract
We report on 90 pre-school children operated on for suspected acute appendicitis. The data analysis was retrospective. The outcome of exploration was negative in 54% (49/90) of cases; inflamed nonperforated appendix was removed 28% (25%/90) and a perforated appendix in 18% (16/90) of cases. In infants aged < 3 years (n = 26) the perforation rate was 60%, and in children age 4-5 years (n = 64) it was 27%. Tenderness in the iliac fossa, blood leukocytosis and urinanalysis had little diagnostic value. Preoperative signs of diffuse peritonitis and elevated values of serum C-reactive protein were found more frequently only in the children with a perforated appendix. There was no mortality and the postoperative morbidity varied between 10 and 20%. Thus, although appendectomy is currently a safe procedure in children, more specific non-invasive diagnostic acids are still needed to reduce the number of negative explorations and the rate of perforation.
