RESUMEN

A woman in her 30s presented to emergency with complaints of acute lower abdominal pain for 3 days, not associated with any menstrual, bowel or urinary symptoms. Examination revealed an abdominopelvic mass corresponding to an 18-week gravid uterus with diffuse tenderness and guarding over her lower abdomen. The patient was a follow-up case of subserosal fibroid uterus, chronic kidney disease stage 4 and rheumatic heart disease on anticoagulants. Fibroid degeneration or torsion was suspected. Ultrasound revealed a large posterior wall subserosal fibroid with free fluid in the pelvis. As findings did not suggest degeneration or pedunculated fibroid, noncontrast CT was done, which showed a similar mass with a pedicle arising from the uterine fundus with free fluid with no other evident cause of acute abdomen. The patient was taken up for emergency laparotomy. Intraoperatively, it was found to be a case of subserosal fibroid with greater omentum adhered to it and twisted around its axis about eight times. This case is being reported to highlight a rare cause of acute abdomen.

RESUMEN

BACKGROUND: Abnormal angular and torsional alignment of the lower extremities during growth are a common reason for consultation of a paediatrician or orthopaedist. There is often uncertainty about the pathological value of these abnormalities and the need for treatment, even among specialists. In the course of physiological growth and development processes, the axial and torsional alignment of the legs sometimes change considerably and in characteristic patterns. DIAGNOSTICS: The ability to assess whether abnormal angular or torsional alignments of the lower limb in the course of growth should still be regarded as normal or already as pathological, depending on age and gender, is essential for the treating physician and requires precise knowledge of the physiological development processes and the tolerable limits in all three spatial dimensions. TREATMENT: After careful explanation to the frequently concerned parents, a restrictive approach with observation of the spontaneous course of correction on the basis of regular clinical check-ups makes sense in the majority of cases. Pathological deviations from the physiological conditions are rare overall, can be idiopathic or of secondary origin and should be further clarified diagnostically using imaging procedures. As conservative measures are ineffective, pronounced angular and/or torsional deformities of the legs requiring treatment can only be corrected by surgical intervention, even in children and adolescents. The surgical treatment modalities available are varied and differ in terms of their invasiveness and complication profile, depending on the localization, type and severity of the deformity, as well as the age and possible concomitant diseases of the affected child or adolescent.

RESUMEN

BACKGROUND: Tubal mesosalpinx cysts are paratubal cysts, that account for approximately 10% of adnexal masses, and the presence of these cysts combined with adnexal torsion is a rare acute abdominal condition, with few cases reported in the literature. We reported two cases of adolescent tubal mesosalpinx cysts combined with adnexal torsion and reviewed the literature to help improve the diagnosis of the disease. CASE REPORTS: The first patient was an 11-year-old girl with left lower abdominal pain for 5 days and fever with nausea and vomiting for 3 days, who was found to have a cystic pelvic mass on preoperative imaging and was diagnosed intraoperatively and postoperatively on pathology as having a left tubal mesosalpinx cyst combined with adnexal torsion. The second patient was a 13-year-old girl with right lower abdominal pain for 16 h and a palpable mass in the lower and middle abdomen on examination, which was hard and tender to palpate. Preoperative imaging revealed a large cystic mass in the right adnexal region, and intraoperative and postoperative pathology revealed a right tubal mesosalpinx cyst combined with adnexal torsion. CONCLUSIONS: Tubal mesosalpinx cysts combined with adnexal torsion are rare causes of acute lower abdominal pain. Early diagnosis and timely surgery are necessary to ensure ovarian and tubal function. Accurate preoperative imaging diagnosis is challenging, and MRI is a beneficial supplement to ultrasound and CT examinations, providing more objective imaging information and reducing the incidence of adverse outcomes.

RESUMEN

In this case report, we present an unusual clockwise torsion of left colon around mesenteric root in a 10-month-old Arab filly, highlighting the clinical presentation, diagnostic approach and successful surgical intervention. A 10-month-old Arab filly weighing approximately 250 kg was referred with signs of acute abdominal pain. The history revealed anorexia, restlessness and severe abdominal pain that had begun the previous day. The local practitioner had previously administered flunixin meglumine, an analgesic, but it proved ineffective in relieving the pain. Upon physical examination, the filly exhibited sweating, a body temperature of 38.5°C, tachycardia (65 beats per minute) and tachypnea (25 breaths per minute). Due to the severity of the colic and the lack of response to the conservative treatments, surgical intervention was deemed necessary. An exploratory midline celiotomy was performed to evaluate the abdominal organs. During the examination, no obvious primary lesions were identified in the evaluated organs. However, a restriction in exteriorizing the left colon's length was observed. Further examination revealed an unusual clockwise torsion of the left colon that displaced in left to the right side around the mesenteric root; thereby, pelvic flexure was located in the normal anatomical position with a short length. To the best of our knowledge, this is the first reported case of clockwise torsion and an atypical displacement of the left colon in horses. The surgical correction of the displacement was successfully performed. The filly showed improvement post-surgery and did not exhibit any complications during the recovery period.

RESUMEN

We aim to explore the alterations of objective ocular torsion after unilateral lateral rectus recession-medial rectus resection (R&R) for intermittent exotropia (IXT). Seventy-two IXT patients undergoing R&R between March and June 2023 were enrolled. Ophthalmological examinations were performed before surgery and at 1 week and 1 month after surgery, mainly including prism and alternate cover test and optical coherence tomography. The mean disc-foveal angle of eyes showing intorsion significantly increased from - 1.5 ± 0.9° preoperatively to 2.0 ± 2.0° at 1 week (P = 0.0227) and 2.2 ± 1.6° at 1 month postoperatively (P = 0.0054). The mean disc-foveal angle of eyes exhibiting extorsion significantly reduced from 12.8 ± 1.9° preoperatively to 9.8 ± 3.1° at 1 week (P < 0.0001) and 9.7 ± 2.7° at 1 month postoperatively (P < 0.0001). The improvement of ocular extorsion at postoperative 1 month was more pronounced in patients with extorsion in operative eye compared to those with extorsion in inoperative eye (P = 0.0101). The improvement of ocular torsion was observed following R&R for IXT, with a greater effect noted in cases where the surgery was performed on the eye exhibiting extorsion.

RESUMEN

This case report discusses a diagnosis of uterine torsion in an 84-year-old woman who presented with five days of right lower quadrant abdominal pain, nausea, vomiting, constipation, and poor intake. Computed tomography (CT) imaging demonstrated a whorled configuration at the junction of the cervix and lower uterine segment, with the left gonadal vein crossing midline, and two previously known right leiomyomas now appearing on the left. These findings were consistent with the diagnosis of uterine torsion. She then underwent an urgent exploratory laparotomy, and the uterus was found to be dextroverted 270 degrees, with dark mottled purple tissue and engorged vessels. A supracervical hysterectomy and bilateral salpingo-oopherectomy were performed. Final pathology demonstrated extensive necrosis. This case reviews the classic presentation and imaging findings for the rare diagnosis of uterine torsion and options for management of both non-gravid and gravid patients.

RESUMEN

ABSTRACT: Gallbladder torsion is a rare cause of acute surgical abdomen. Early recognition and surgical intervention are important for reducing complications and improving postoperative patient outcomes, but standard imaging and laboratory evaluation typically are indistinguishable from those of acute cholecystitis. This article describes a patient with gangrenous cholecystitis secondary to torsion and summarizes recommendations for evaluation and management.

RESUMEN

BACKGROUND Persistent truncus arteriosus is a rare congenital cyanotic heart defect characterized by a single ventricular outflow tract. Without surgical intervention, it has a poor prognosis in infancy. Here, we report an adult female patient with uncorrected truncus arteriosus type I, who presented with acute-onset abdominal pain due to torsion of a small bowel gastrointestinal stromal tumor (GIST). CASE REPORT A 41-year-old woman came to our Emergency Department with acute-onset lower abdominal pain for 2 days. Congenital heart disease, truncus arteriosus, had been diagnosed at birth, and there had been no surgical intervention. Abdominal computed tomography revealed a 10×9×12-cm mixed-density mass in the pelvic capacity. Transthoracic echocardiography revealed a 33-mm ventricular septal defect. The ascending aorta originated mainly from the right ventricle, and the pulmonary artery originated from the beginning of the aorta (type I truncus arteriosus, according to Collett and Edwards classification). After a quick and detailed preoperative workup, the patient underwent tumor resection by open surgery with general anesthesia. CONCLUSIONS This is the first case to report emergency surgery for a patient with uncorrected persistent truncus arteriosus due to torsion of a small bowel GIST. A multidisciplinary team with deep understanding of the disease entity was crucial. By considering the fixed hemodynamic and respiratory physiology, overtreatment and unrealistic goals were avoided. Eventually, the patient was discharged after being hospitalized for 2 weeks.

RESUMEN

We report four cases of isolated fallopian tube torsion (IFTT) successfully treated with laparoscopic surgery over the past 10 years. Two young women (each 19 years old) were IFTT with paraovarian cyst (POC) and tubal preservation was possible with detorsion and cystectomy. The other two patients (a 41-year-old woman with hydrosalpinx and a 50-year-old woman with hematosalpinx) underwent salpingectomy and adnexectomy, respectively, because there was no desire for tubal preservation. One patient had emergency surgery due to severe abdominal pain, one had semi-emergency surgery due to mild abdominal pain, and the other two were diagnosed during scheduled surgery without symptoms.Although IFTT was considered a very rare disease, our case series and recent reports suggest that it may have been underestimated, as it accounts for approximately 10% of adnexal torsion cases. Preoperative diagnosis of IFTT may be more difficult than for adnexal torsion because of its infrequency and nonspecific, vague clinical symptoms.　Since the prevalent age for this disease is young, as in our first 2 patients, early surgical intervention to preserve the fallopian tubes should be chosen when necessary, and it seems to be important for gynecologists to be aware of this disease for earlier diagnosis and appropriate surgical intervention.

RESUMEN

PURPOSE: The purpose of this study was to investigate whether double-level (femur + tibia) derotational osteotomy is superior to single-level femoral derotational osteotomy for recurrent patellar dislocation with severe femoral and tibial rotational deformities (femoral anteversion >30° and external tibial torsion >30°). METHODS: Between January 2015 and June 2020, a total of 115 knees with recurrent patellar dislocation treated with combined medial patellofemoral ligament reconstruction (MPFL-R) and derotational osteotomies were evaluated after a minimum follow-up of 2 years. Among these cases, 15 knees that underwent double-level derotational osteotomy were included in the double-level group, which was propensity-matched in a 1:2 ratio to a single-level group of patients who underwent single-level femoral derotational osteotomy (30 knees). The clinical and radiological outcomes were evaluated and compared between the groups. Furthermore, the foot progression angle was measured preoperatively and 2 years after surgery. RESULTS: The patient-specific variables did not differ significantly between the double- and the single-level groups after propensity score matching. The postoperative mean foot progression angle was significantly lower in the double-level group than in the single-level group (9° ± 8° vs. 15° ± 11°; p = 0.014); however, there were no statistically significant differences between the groups in terms of any other clinical and radiological assessments. CONCLUSION: For patients with severe femoral and tibial torsional deformities (femoral anteversion >30° and external tibial torsion >30°), the double-level derotational osteotomy is superior to single-level osteotomy in maintaining normal foot progression angle, but it does not show an advantage in terms of patient-reported outcomes, radiological results and redislocation rate at minimum 2 years of follow-up. Furthermore, concomitant excessive external tibial torsion (>30°) did not have an adverse effect on clinical outcomes in patients who underwent derotational distal femoral osteotomy with MPFL-R due to excessive femoral anteversion. LEVEL OF EVIDENCE: Level III.

RESUMEN

Primary segmental omental torsion (PSOT) is a very rare cause of acute abdominal pain, and it may often imitate the clinical picture of acute appendicitis. In instances of acute abdominal pain without anorexia, nausea, and vomiting, omental torsion should be included in the differential diagnosis. Any misdiagnosis may lead to major complications such as intraabdominal abscesses and adhesions. A 63-year-old overweight man with a body mass index (BMI) of 41 Kg/m2 presented to the emergency department on a remote island with acute abdominal pain. His medical history included type 2 diabetes mellitus managed with insulin, essential hypertension, osteoarthritis, and no previous abdominal operations. He reported a sharp pain originating in the epigastrium and the right hypochondrium that started five days prior. Physical examination revealed rebound tenderness and guarding across the abdomen with a positive McBurney sign. However, the patient did not report vomiting and was not nauseous. Vital signs were as follows: blood pressure 116/56 mmHg, heart rate 98 beats/min, respiratory rate 19 breaths/min, and a temperature of 38.2 0C. Laboratory results showed a white blood cell count of 10.6, neutrophils of 8.11, C-reactive protein (CRP) 74 mg/l, haemoglobin11.6 g/dl, and hematocrit 36.9%. Due to the absence of a radiographer at the hospital during that period, no imaging investigations were conducted. Diagnostic laparoscopy demonstrated diffused hemoperitoneum and necrotic mass at the site of the hepatic flexure. Initially suspected to be an advanced colon cancer, the decision was made to proceed with open surgery. The necrotic segment of the omentum was found at the right superior point of attachment of the omentum to the hepatic flexure. Consequently, the necrotic segment of the omentum was resected. A thorough investigation of the abdominal cavity did not detect any other abnormalities or pathologies. The patient recovered uneventfully and was transferred to the surgical ward. Torsion of the omentum is a very rare cause of acute abdominal pain. This case highlights the necessity of considering PSOT in the differential diagnosis of acute abdominal pain, especially in cases where symptoms are suggestive of appendicitis but diagnostic findings are negative.

RESUMEN

PURPOSE: Isolated fallopian tube torsion (IFTT) is defined by rotation of the fallopian tube around itself without involving the ipsilateral ovary. It is a rare cause of acute lower abdominal pain in (adolescent) girls, but is commonly overlooked. Due to its rarity, literature is still scarce. Currently there is no generally accepted management and treatment. METHODS: A retrospective analysis of all IFTT cases treated in our institution was performed. In addition, a systematic literature research on pediatric IFTT was carried out on Medline/ PubMed database according to PRISMA principles using predefined search terms and inclusion criteria. Patient characteristics regarding age, clinical symptoms, diagnostic methods, treatment, and follow-up were analyzed. RESULTS: Three of our patients and fifty-nine reports totaling one hundred seventy girls were included in the analysis. Mean age was 13.0 years. Left tube was slightly more often affected (52.9%). Abdominal pain was present in 99.4% of cases accompanied with nausea in 57.1%. In only 16.4%, correct preoperative diagnosis was made. Salpingectomy was the most common treatment in 111 (66.9%) cases, 55 (33.1%) patients were treated with detorsion of the tube (organ-sparing management). Girls with symptoms longer than 1 day had a significant higher rate of salpingectomy (95% CI, P = 0.0323). CONCLUSION: When IFTT is suspected, emergency laparoscopy should be performed to possibly preserve future reproductive potential. In case of detorsion and reinstated blood supply, organ-preserving management should be performed with simultaneous addressment of concomitant pathology if possible. Sufficient long-term follow-up must be assured to get significant results to introduce guidelines for children and adolescents.

RESUMEN

Objective: The preliminary results was reported regarding the treatment of mesenteric torsion by mesenteric fixation in the last decade, especially preventing recurrence of mesenteric torsion by mesenteric fan-shaped fixation. Methods: We selected 12 patients who received emergency operation in Chongqing Hospital of the First Affiliated Hospital of Guangzhou University of Chinese Medicine from December 2010 to March 2022. All of them were made a definite diagnose of mesenteric torsion by the preoperative CT scan or exploratory laparotomy. The recurrence of mesenteric torsion will be prevented by taking the operation of mesenteric fan-shaped fixation. This technique is suitable for the patient who is suffering total mesenteric torsion, but enteric necrosis is excluded affirmatively. The operation is consists of the following progress: (1) Exploratory laparotomy to check for necrosis of the bowel and for lesions other than torsion. (2) Mesenteric torsion derotation.(3) Mesenteric linear fixation; the right posterior lower border of the small mesentery (terminal ileal mesentery) is intermittently sutured to the posterior peritoneum of the right lower quadrant to increase the width of the base of the small mesentery. (4) Mesenteric fan-shaped fixation, which is fan-shaped to the lower left and fixed in the posterior peritoneum, shortening the length of the mesentery and further increasing the width of the mesentery and posterior peritoneal fixation. Results: A total of 12 patients with mesenteric torsion were treated by operation for 15 times in all. Among them, 3 cases received resection of most small bowel were performed without recurrence; 3 patients received only derotation for a total of 4 times, 2 cases recurred, 1 of them recurred twice; 4 cases underwent derotation and mesenteric linear fixation,and 1 case recurred. Four patients with derotation and mesenteric fan-shaped fixation recovered well without recurrence. Conclusion: Mesenteric fan-shaped fixation may be an effective operative type to reduce or avoid postoperative recurrence of mesenteric torsion.

RESUMEN

BACKGROUND: Isolated fallopian tube torsion (IFTT) is very rare gynecological emergency in pediatric population. Our objective is to assess treatment options and discuss outcome of a cohort of IFTT with a focus on the association between IFTT and hydrosalpinx (HSX). METHODS: A retrospective review was conducted. Pediatric patients with IFTT operated in the same center were included. RESULTS: Seventeen girls (aged: 11-16 years) were managed for acute abdominal pain between 2008 and 2018, with intraoperative diagnosis of IFTT. All patients underwent laparoscopic exploration, with laparoscopically fallopian tube detorsion in all patients. Based on the association of IFTT with HSX after fallopian tube detorsion, patients were divided into 2 groups: group 1 (IFTT without HSX; 12 girls) and group 2 (IFTT with HSX; 5 girls). During the same surgery, complementary surgical procedures were done. In group 1: salpingectomies (4), partial salpingectomies (2) and cystectomies (6) were done. In group 2: salpingectomy (1), salpingotomy (1), and cyst ablation (1). The treatment was called conservative when the tube was preserved.Follow-up was uneventful in group 1. In group 2, for all patients with initial fallopian tube preservation, further surgical procedures were necessary (1-4 surgeries/patient), and, finally, another 3 patients required salpingectomy. CONCLUSIONS: Conservative treatment with tube preservation of IFTT without HSX appeared to be beneficial compared to those with HSX, with no recurrence of torsion or symptoms during the follow-up. However, the same conservative treatment was not sufficiently effective for IFTT with HSX and required further procedures due to recurrence of torsion. LEVEL OF EVIDENCE: IV.

RESUMEN

A pregnant female domestic longhair cat ~8 mo of age was referred to the Western College of Veterinary Medicine (Saskatoon, Saskatchewan) for a diagnostic evaluation of severe anemia (PCV: 10.8%) after a 2-day period of lethargy. A CBC, serum biochemistry profile, FeLV/FIV testing, and abdominal radiographs were completed and did not determine a cause for the anemia. Abdominal ultrasonography identified 1 viable and 6 nonviable and fetuses, anechoic fluid in the uterus, and a mild volume of peritoneal effusion. A whole-blood transfusion and C-section with ovariohysterectomy were performed even though a definitive presurgical diagnosis for the anemia had not yet been established. Exploratory surgery revealed a left uterine horn torsion with a necrotic base, severe congestion, and 7 nonviable fetuses. Following surgery, the queen made a full clinical recovery. Key clinical message: Uterine torsion can be easily overlooked as a cause of severe anemia due to the relative infrequency of this condition in cats and the low sensitivity of ultrasonography to provide a definitive presurgical diagnosis. Client communication must emphasize the need for a prompt surgical intervention to establish the diagnosis and to save the cat, despite poor rates of neonatal survival. Once the animal is stabilized after surgery, further diagnostic tests and procedures are indicated if the cause of anemia has not yet been identified.

Reconnaître la torsion utérine comme un diagnostic différentiel chez les chattes gestantes souffrant d'anémie sévère afin de fournir des soins appropriés et opportuns en l'absence d'un diagnostic pré-chirurgical définitif. Une chatte domestique à poils longs, âgée d'environ 8 mois, a été référée au Western College of Veterinary Medicine (Saskatoon, Saskatchewan) pour une évaluation diagnostique d'anémie sévère (hématocrite : 10,8 %) après une période de léthargie de 2 jours. Une formule sanguine complète, un profil biochimique sérique, des tests FeLV/FIV et des radiographies abdominales ont été réalisés et n'ont pas permis de déterminer la cause de l'anémie. L'échographie abdominale a identifié 1 foetus viable et 6 non viables, du liquide anéchoïque dans l'utérus et un léger volume d'épanchement péritonéal. Une transfusion de sang total et une césarienne avec ovariohystérectomie ont été réalisées même si le diagnostic pré-chirurgical définitif de l'anémie n'avait pas encore été établi. La chirurgie exploratoire a révélé une torsion de la corne utérine gauche avec une base nécrotique, une congestion sévère et 7 foetus non viables. Après l'opération, la chatte s'est complètement rétablie cliniquement.Message clinique clé:La torsion utérine peut facilement être négligée comme cause d'anémie sévère en raison de la rareté relative de cette affection chez le chat et de la faible sensibilité de l'échographie pour fournir un diagnostic pré-chirurgical définitif. La communication avec le client doit souligner la nécessité d'une intervention chirurgicale rapide pour établir le diagnostic et sauver le chat, malgré de faibles taux de survie néonatale. Une fois l'animal stabilisé après la chirurgie, d'autres tests et procédures de diagnostic sont indiqués si la cause de l'anémie n'a pas encore été identifiée.(Traduit par Dr Serge Messier).

RESUMEN

To describe the clinical presentation, diagnosis, perioperative management and the short- and long-term outcomes of a dog diagnosed with pancreatic torsion. A 3-month-old female intact Bernese Mountain dog presented for an acute onset of vomiting, anorexia and abdominal pain. Abdominal ultrasonography showed a hypoechoic mass effect cranial to the stomach. A pancreatic torsion was diagnosed during exploratory laparotomy and treated with partial pancreatectomy. Histopathology confirmed pancreatic torsion. The patient recovered uneventfully and pancreatic function and inflammation testing that was performed 14 months postoperatively showed no evidence of ongoing dysfunction. This is the first report that demonstrates long-term follow-up with pancreatic function testing in a patient who had a partial pancreatectomy due to pancreatic torsion. There was no evidence of long-term pancreatic dysfunction due to partial pancreatectomy secondary to pancreatic torsion. Additionally, this is the youngest patient with pancreatic torsion to be described in the veterinary literature.

RESUMEN

PURPOSE: The aim of this systematic review was to identify the surgical indications of tibial derotational osteotomy (TDO) in patients with idiopathic external tibial torsion (ETT) and identify common measurement thresholds for surgical correction. METHODS: A systematic search of MEDLINE and Embase via Ovid, Cochrane Library via Wiley, Web of Science, Scopus, SPORTDiscus via EBSCOhost, ClinicalTrials.gov, WHO ICTRP and Global Index Medicus databases was performed with search terms reflecting the concepts of idiopathic tibial torsion, TDOs, and surgical indications. Studies reporting surgical indications and measurement methods of idiopathic tibial torsion in patients who underwent TDO were included. Two authors independently screened articles and extracted data that was characterized with descriptive statistics. RESULTS: Seventeen studies were identified for inclusion, with 460 tibias and 351 patients. Nearly all patients who underwent surgery had either anterior knee pain or patellar instability, even if other indications were present. Of all included patients, the most common surgical indications for TDO were anterior knee pain (88%), patellar instability (59%), gait dysfunction (41%) and cosmetic deformity (12%). Twelve studies (71%) cited multiple of these indications as reasons for surgery. On physical exam, tibial torsion was measured most commonly by thigh-foot angle (59%) (TFA) and transmalleolar axis (24%) (TMA). In terms of TFA, the most frequently reported cut-off for ETT was >30° (35%). Computerized tomography (CT) was used by nine studies (53%). The most common CT axes used to measure ETT were the TMA with respect to the posterior tibia condylar axis or the bicondylar tibia axis. CONCLUSION: Anterior knee pain and/or patellar instability are common indications for TDO in patients with idiopathic tibial torsion. Standardized TFA thresholds (>30°) and CT measurement methods (TMA and posterior tibia condylar or bicondylar tibial axis) may help further establish objective surgical indications. LEVEL OF EVIDENCE: IV.

RESUMEN

BACKGROUND/AIM: Primary omental torsion is uncommon, mimicking appendicitis and other acute abdominal pathologies. It often escapes diagnosis on imaging investigation or conventional open laparotomy. This study aimed to evaluate the effect of laparoscopy on the various parameters of this entity, including incidence, diagnosis, and treatment. MATERIALS AND METHODS: A systematic review was performed, including PubMed and Scopus databases, without a time limit, following the PRISMA principles. A total of 16 articles from January 2000 to December 2023, corresponding to 56 children with primary omental torsion, complied with the research criteria. RESULTS: Primary omental torsion was associated with obesity. Symptoms were right abdomen oriented, often compared to those of acute appendicitis. Preoperative ultrasound displayed low diagnostic accuracy, whereas computerized tomography diagnosed only two thirds of cases. In all patients, the vermiform appendix was normal. CONCLUSION: Laparoscopy affected both diagnosis and treatment of primary omental torsion in children. Easy peritoneal cavity access rendered possible the diagnosis of cases previously discharged as abdominal pain of unknown etiology. Combined with the increased pediatric obesity, it also affected primary omental torsion incidence. The recent pathogenetic theories may be better supported today, as laparoscopy provides a detailed view in situ, and facilitates harvesting of fat tissue from the omentum for molecular investigation. The diagnostic efficiency of laparoscopy is superior to ultrasonography and computerized tomography. Finally, the removal of the ischemic omentum is technically easier compared to the open laparotomy alternative with all the technical difficulties of traction of a vulnerable hemorrhagic tissue through a small incision.
