Liver metastases from prostate cancer at 11C-Choline PET/CT: a multicenter, retrospective analysis.

AIM: During our daily clinical practice using 11C-Choline PET/CT for restaging patients affected by relapsing prostate cancer (rPCa) we noticed an unusual but significant occurrence of hypodense hepatic lesions with a different tracer uptake. Thus, we decided to evaluate the possible correlation between rPCa and these lesions as possible hepatic metastases. MATERIALS AND METHODS: We retrospectively enrolled 542 patients diagnosed with rPCa in biochemical relapse after a radical treatment (surgery and/or radiotherapy). Among these, patients with a second tumor or other benign hepatic diseases were excluded. All patients underwent 11C-Choline PET/CT during the standard restaging workup of their disease. We analyzed CT images to evaluate the presence of hypodense lesions and PET images to identify the relative tracer uptake. In accordance to the subsequent oncological history, five clinical scenarios were recognized [Table 1]: normal low dose CT (ldCT) and normal tracer distribution (Group A); evidence of previously unknown hepatic round hypodense areas at ldCT with normal rim uptake (Group B); evidence of previously known hepatic round hypodense areas at ldCT stable over time and with normal rim uptake (Group C); evidence of previously known hepatic round hypodense areas at ldCT, in a previous PET/CT scan, with or without rim uptake and significantly changing over time in terms of size and/or uptake (Group D); evidence of hepatic round hypodense areas at ldCT with or without rim uptake confirmed as prostate liver metastases by histopathology, triple phase ceCT, ce-ultra sound (CEUS) and clinical/biochemical evaluation (Group E). We evaluated the correlation with PSA level at time of scan, rim SUVmax and association with local relapse or non-hepatic metastases (lymph nodes, bone, other parenchyma). RESULTS: Five hundred and forty-two consecutive patients were retrospectively enrolled. In 140 of the 542 patients more than one 11C-choline PET/CT had been performed. A total of 742 11C-Choline PET/CT scans were analyzed. Of the 542 patients enrolled, 456 (84.1%) had a normal appearance of the liver both at ldCT and PET (Group A). 19/542 (3,5%) belonged to Group B, 13/542 (2.4%) to Group C, 37/542 (6.8%) to Group D and 18/542 (3.3%) to Group E. Mean SUVmax of the rim was: 4.5 for Group B; 4.2 for Group C; 4.8 for Group D; 5.9 for Group E. Mean PSA level was 5.27 for Group A, 7.9 for Group B, 10.04 for Group C, 10.01 for Group D, 9.36 for Group E. Presence of positive findings at 11C-Choline PET/CT in any further anatomical area (local relapse, lymph node, bone, other extra hepatic sites) correlated with an higher PSA (p = 0.0285). In both the univariate and multivariate binary logistic regression analyses. PSA, SUVmax of the rim, local relapse, positive nodes were not associated to liver mets (Groups D-E) (p > 0.05). On the contrary, a significant correlation was found between the presence of liver metG (group D-E) and bone lesions (p= 0.00193). CONCLUSION: Our results indicate that liver metastases in relapsing prostate cancer may occur frequently. The real incidence evaluation needs more investigations. In this case and despite technical limitations, Choline PET/CT shows alterations of tracer distribution within the liver that could eventually be mistaken for simple cysts but can be suspected when associated to high trigger PSA, concomitant bone lesions or modification over time. In this clinical setting an accurate analysis of liver tracer distribution (increased or decreased uptake) by the nuclear medicine physician is, therefore, mandatory.

Effects of dark chocolate on endothelial function in patients with non-alcoholic steatohepatitis.

BACKGROUND AND AIM: Oxidative stress plays a pivotal role in inducing endothelial dysfunction and progression from simple fatty liver steatosis (FLD) to non-alcoholic steatohepatitis (NASH). Polyphenols could reduce oxidative stress and restore endothelial function by inhibiting the nicotinamide-adenine-dinucleotide-phosphate (NADPH) oxidase isoform Nox2. The aim of this study was to assess endothelial function and oxidative stress in a population affected by simple FLD and NASH. Furthermore, we analysed the effect of high vs low content of cocoa polyphenols on endothelial function and oxidative stress in patients with NASH. METHODS: In a cross-sectional study we analysed endothelial function, as assessed by flow-mediated dilation (FMD), and oxidative stress, as assessed by Nox2 activation, serum isoprostanes and nitric oxide bioavailability (NOx), in patients with NASH (n = 19), FLD (n = 19) and controls (n = 19). Then, we performed a randomized, cross-over study in 19 subjects with NASH comparing the effect of 14-days administration of 40 g of chocolate at high (dark chocolate, cocoa >85%) versus low content (milk chocolate, cocoa <35%) of polyphenols on FMD and oxidative stress. Compared to controls, NASH and FLD patients had higher Nox2 activity and isoprostanes levels and lower FMD and NOx, with a significant gradient between FLD and NASH. The interventional study showed that, compared to baseline, FMD and NOx increased (from 2.9 ± 2.4 to 7.2 ± 3.0% p < 0.001 and from 15.9 ± 3.6 to 20.6 ± 4.9 µM, p < 0.001, respectively) in subjects given dark but not in those given milk chocolate. A simple linear regression analysis showed that Δ (expressed by difference of values between before and after 14 days of chocolate assumption) of FMD was associated with Δ of Nox2 activity (Rs = -0.323; p = 0.04), serum isoprostanes (Rs: -0.553; p < 0.001) and NOx (Rs: 0.557; p < 0.001). CONCLUSIONS: Cocoa polyphenols improve endothelial function via Nox2 down-regulation in NASH patients.

Small bowel intussussception due to metastatic melanoma of unknown primary site. Case report.

Malignant melanoma is characterized by metastases also to the gastrointestinal tract, especially in the small bowel. The diagnosis is often delayed because unspecific clinical presentation (frequently as chronic iron deficiency anemia, rectal bleeding or intestinal obstruction). We present a case of melanoma of unknown primary site, with clinical presentation of intestinal obstruction. A segmental resection of the ileum was performed including mesentery with lymph nodes. Histology revealed metastatic melanoma from unknown primary. PET and MRI confirmed disseminated disease without brain metastasis.

Biliodigestive fistulae and gallstone ileus: diagnostic and therapeutic considerations. Our experience.

The biliodigestive fistula is not a rare affection in the context of acute pathology of the gastrointestinal tract. It often affects patients between 63 and 85 years old , particularly the female sex, and the most common cause is acute or chronic cholecystolithiasis. Open issues are the delayed in the pre-operative diagnosis, and controversies exist regarding the best surgical approach. The choice of treatment options is influenced by the age of the patients and their clinical conditions and also by the presence of comorbidities and of a delayed right diagnosis. In the 1 to 3% of cases, the biliodigestive fistula presents a gallstone ileus as complication, whose diagnosis is particularly difficult for the lack of specific signs and symptoms. The contrast-enhanced CT is considered the gold standard for a specific pre-operative diagnosis, as it directly shows the fistula. Surgical treatments include one-stage procedure or two-stage procedure. Many studies seem to favor a deferred definitive procedure. The Authors describe 4 cases: in 3 cases, women between 70 and 80 years old presenting an history of recurrent cholecystitis, in 2 cases, and in 1 case presenting a bowel obstruction; in 1 case a 50-years-old man, with no significant past medical history, presenting a bowel obstruction. The Authors have performed in the 2 cases of gallstone ileus an enterolithotomy with cholecysto-duodenal fistula repair and cholecystectomy, in one-stage, and this has been possible because of the good clinical conditions of the patients and their low operative risk. In the case of fistula without the complication of gallstone ileus, the treatment approach has been cholecysto-gastric fistula closure with a gastroplastic using separate stitches and cholecystectomy, in one-stage. We are in agreement with data in the literature regarding the delay into the diagnosis of biliodigestive fistula and with the importance to suspect it or gallstone ileus presence, although the clinical presentation is extremely non-specific. In our experience, cholangiopancreatography-CT and CECT have made easier the pre-operative diagnosis and so reducing the delay of the treatment.

Technique and outcomes about a new laparoscopic procedure: the Pelvic Organ Prolapse Suspension (POPS).

Pelvic organ prolapse suspension (POPS) is a recent surgical procedure for one-stage treatment of multiorgan female pelvic prolapse. This study evaluates the preliminary results of laparoscopic POPS in 54 women with a mean age of 55.2 and a BMI of 28.3. Patients underwent at the same time stapled transanal rectal resection (STARR) to correct the residual rectal prolapse. We had no relapses and the preliminary results were excellent. We evaluated the patients after 1 year follow-up and we confirmed the validity of our treatment. The technique is simpler than traditional treatments with an important reduction or completely disappearance of the pre-operative symptomatology.

Risk management in surgery.

Malpractice is the responsible for the greatest number of legal claims. At the present time, legal actions against physicians in Italy are 15,000 per year, and a stunning increase about costs to refund patients injured by therapeutic and diagnostic errors is expected. The method for the medical prevention is "Risk Management", that is the setting-up of organizational instruments, methods and actions that enable the measurement or estimation of medical risk; it allows to develop strategies to govern and reduce medical error. In the present work, the reconstruction about the history of risk management in Italy was carried out. After then the latest initiatives undertaken by Italy about the issue of risk management were examined.

Single-incision laparoscopic appendectomy is comparable to conventional laparoscopic and laparotomic appendectomy: our single center single surgeon experience.

Several studies have demonstrated the clinical and technical benefits of the laparoscopic surgery for complicated and uncomplicated appendicitis. Our retrospective study included 12 patient who underwent SILS appendectomy (SILS-A), 14 who received conventional laparoscopic surgery (VL-A), and 12 who received laparotomic appendectomy (OA); performed in all cases by the same surgeon (C.F.). The aim of this study was the comparison between this three different surgical techniques on same features: post operative leukocytosis, post operative pain, need abdominal drainage, esthetic viewpoint, incidence of complication, hospital stay. The results showed no significant differences between SILS-A and VLS-A, while an evident improvement shows versus O-A, even though not statistically significative. SILS was more effective in decreasing the risk of postoperative wound infection.

Cholecystectomy by single incision laparoscopic surgery (SILS): early experience and technique standardization.

Single Incision Laparoscopic Surgery (SILS) is a recent surgical technique, first described in the 1990s. Its aim is to optimize the esthetic result offered by laparoscopy by minimizing the number of abdominal incisions. Various preliminary studies have been carried out on the application of SILS, especially in cholecystectomy and appendectomy. This study evaluates the preliminary results of cholecystectomy by SILS (SILS™ Port) conducted between October 2009 and February 2011 on 21 patients (4 men and 17 women) with a mean age of 49.9 years and a mean Body Mass Index (BMI) of 22.8. All patients were treated by the same team, which had previously undergone six months' simulator training. There were two main selection criteria, both evaluated intraoperatively: absence of adhesions and of significant inflammatory sequelae from previous cholecystitis; and suitable distance between gallbladder and SILS access port. Conversion to traditional laparoscopy was necessary in just two cases, while an accessory trocar was introduced in another two cases. Conversion to open surgery was not necessary in any case. One case of SILS cholecystectomy was complicated by postoperative bile leakage, which was treated conservatively, as the fistula had a low output. The mean duration of hospitalization was 3.6 days. This preliminary experience led us to conclude that SILS is safe and highly satisfactory in the postoperative phase, thanks to the reduced need for painkillers and the improved esthetic result.

Liver resection for hemoperitoneum caused by spontaneous rupture of unrecognized hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is an increasingly common form of cancer. Although its spontaneous rupture is rare in Western countries, it constitutes a surgical emergency and is associated with high mortality. There is a lack of consensus as to the best approach and what parameters to use in choosing it. The three main approaches are conservative, endovascular and resection - the treatment of choice for acute abdominal bleeding. We report a case of hemoperitoneum following the spontaneous rupture of an unrecognized HCV-related HCC in a patient with no history of liver disease. The patient was successfully treated by emergency surgery, with resection of two segments of the left liver.

Posterior interosseous nerve palsy by synovial cyst of proximal radioulnar joint: our experience after 5 years.

AIM: The posterior interosseous nerve palsy is a neuropathy of radial nerve interesting its deep motor branch. The neuropathy can appear with a hollow in the proximal half of the forearm without significant swelling, a complete loss of extension of the fingers with radial deviation of the wrist during extension. In some cases, PIN compression may simulate tendon rupture in rheumatologic diseases, because the pain and the paralysis occur suddenly, so often can be difficult to make a diagnosis. The palsy is caused by compression of the posterior interosseous nerve from soft tissue tumours or tumour-like masses: ganglions, lipomas, rheumatoid synovitis, synovial chondromatosis, fibromas, neurofibromas, bursitis, synovial cysts of the elbow and radioulnar proximal joints. The aim of our research was to individuate the better treatment for the posterior interosseous nerve palsy. METHODS: From 2002 to 2007 we examined 8 patients: 2 female and 6 male. Median age was 43 years. The diagnosis was made by clinical examination, ultrasound, nerve conduction studies and magnetic resonance imaging (MRI). Patients underwent to decompressing posterior interosseous nerve surgery. RESULTS: After the surgical exploration in 8 cases a globular mass of around 2.5 cm to 4.5 cm diameter was discovered. At the histological examination, a synovial cyst of the elbow joint was found in 7 out of 8 patients and an hemangioma tumor in the one remaining patient. 12 months was the median time for a complete recovery after the operation, confirmed by EMG. CONCLUSION: The surgical treatment offers a complete resolution in all cases.

[Mesh infection in inguinal hernioplasty by Streptococcus dysgalactiae subspecies equisimilis. Case report and review of the literature]. / Infezione da Streptococcus dysgalactiae subspecies equisimilis in ernioplastica inguinale. Caso clinico e revisione della letteratura.

INTRODUCTION: Mesh infection in inguinal herniography is usually caused by Staphilococcus aureus and Staphilcoccus epidermidis. Generally it obliges to prosthesis removal with hernia relapse and increase of social costs for the prolongation of hospitalization. CASE REPORT: A 60-year-old woman, obese, undergone 4 months before to left inguinal prosthetic herniorrhaphy complicated by infection of the surgical site which didn't require the explantation of the mesh, although determining an early hernia relapse. She is submitted by the authors to a surgical intervention for left groin hernia relapse with placement of a polypropylene monofilament fixed with prolene. Six hours after the operation she shows systemic symptoms and local signs of prosthesis infection. Cultural examination of the surgical wound secretion allows the identification of Streptococcus dysgalactiae subspecies equisimilis (SDSE). A therapy with Amoxicillin-Clavulanic Acid and Levofloxacine leads to resolution, in 10 weeks, of the infection. DISCUSSION: In our case the infection of the new mesh, appearing prematurely, has been probably favoured by obesity and operative time longer than 3 hours. Conservative treatment has been fulfilled by success for the elevated sensitivity of the SDSE bacterium to penicillin and fluoroquinolones. CONCLUSIONS: Recent epidemiologic studies have demonstrated an increase of infections caused by SDSE, which will probably gain clinical relevance in the next future relatively to surgical prosthetic hernioplasty. In all cases of infection the authors suggest cultural isolation of the casual germ and the execution of the antibiogram because the conservative medical treatment can avoid mesh removal with consequent elevated risk of hernia relapse.

Re-do surgery after prosthetic abdominal wall repair: intraoperative findings of mesh-related complications.

INTRODUCTION: Mesh repair is one of the most popular technique for the treatment of abdominal wall hernias, resulting in lower recurrence rates. However, it is associated with a high risk of mesh-related complications. The aim of the present study is to assess the impact of biomaterials on the intra-abdominal organs, in terms of adhesions and visceral complications, in a series of patients undergoing re-do surgery at our abdominal wall unit. MATERIALS AND METHODS: We reviewed the clinical records of 301 patients who undergone laparotomy between June 2008 and May 2018, selecting 67 patients with one or more previous prosthetic abdominal wall repair (AWR). RESULTS: The average number of previous repairs was 1.6 with a mean time interval of 66 months from the last repair. Clinical presentation included hernia recurrence (69%), mesh infection (26%), infection and recurrence (10%), and fistula (1%). Adhesions were intraoperatively observed in all patients, except for eight cases. Mesh was completely removed in 43 patients, partially in four. Postoperative complications were observed in 39% of cases, including wound dehiscence, hematoma, seroma, and mesh infection. CONCLUSIONS: Long-term implant results in abdominal wall repair and are not completely known, and literature is still lacking on this topic. Re-do surgery for subsequent pathological events may represent a way to increase our knowledge.

Cannabis use disorder and dissociation: A report from a prospective first-episode psychosis study.

BACKGROUND: Cannabis is the most used recreational drug worldwide. Its use can increase the risk of developing psychotic disorders and exacerbate their course. However, the relationship between cannabis use and dissociative symptoms has been scarcely investigated. AIMS: To examine differences in psychotic and dissociative symptoms, and in functioning in first-episode psychotic patients (FEPp) using cannabis compared with those not using cannabis. METHODS: Between January 2014 and December 2019, seventy FEPp with cannabis use disorder (N = 35) and without it (N = 35) were recruited in psychiatric inpatient facilities in the Italian regions of Lazio and Piemonte. All subjects were assessed at FEP, after 4 and 8 months, using the Positive and Negative Syndrome Scale (PANSS), the Global Assessment of Functioning (GAF) scale and the Dissociative Experiences Scale - II (DES-II). Detailed information on the pattern of cannabis and other substance use were collected. RESULTS: FEP using cannabis showed higher levels of positive symptomatology, dissociative experiences and worse functioning than their non-user counterpart, despite a comparable antipsychotic treatment. At an eight-month prospective evaluation, FEP using cannabis still showed higher levels of positive symptomatology and dissociation. Moreover, global functioning worsened over time in FEPp using cannabis, whereas it improved those not using it. DISCUSSION: Our findings suggest that a greater degree of dissociation and positive symptoms at FEPp and their persistence over time may characterise cannabis-associated psychosis. Both these factors might explain the overall functioning worsening over time that we observed in the cannabis-user group compared to the functioning improvement in the non-user group.

[Gallbladder polypoid lesions. Three clinical cases with difficult diagnosis and literature review]. / Lesioni polipoidi della colecisti. Presentazione di tre casi clinici di "difficile" diagnosi e revisione della letteratura.

INTRODUCTION: Gallbladder polypoid lesions occur in 1.3%-6.9% of cases. The preoperative diagnosis between benign, malignant and potentially malignant lesions is difficult. Therefore it is not possible any. PATIENTS AND METHODS: The Authors describe three cases. The case 1 was a gallbladder diffuse adenomyomatosis; the ultrasound and the CT were of little help in defining preoperatively the nature and the gravity of the thickening. Case 2 was an adenomyomatosis of the fundus: the ultrasound examinations were not able to establish preoperatively lesion's nature, site and dimensions. In the case 3, ultrasounds showed polypoid lesions and calculi concrections not found in colecistectomy. DISCUSSION: The ultrasound is the most widely used diagnostic tool in the evaluation of gallbladder polypoid lesions; its accuracy is only 66%. CT, which has an accuracy level of 75%, must be carried out there is any possibility of malignant degeneration of the polyp. If doubts persist, a MR, 93% accuracy, is indicated. In selected cases, PET can be of further help. CONCLUSIONS: The preoperative diagnosis of the nature of gallbladder polypoid lesions is "difficult" and this justifies the lack of consensus on treatment. However, the adenoma-carcinoma sequence, widely discussed in literature, can justifies to the use of CT, MR, PET and surgical treatment after an ultrasound examination.

[A rare cause of acute abdomen: splenic infarction. Case report and review of the literature]. / Rara causa di addome acuto: l'infarto splenico. Caso clinico e revisione della letteratura.

INTRODUCTION: Splenic infarction is a rare cause of acute abdomen. It must be suspected in patient with hematologic diseases or thromboembolic conditions. The most common onset symptom is left-upper quadrant abdominal pain. Additional symptoms include fever and anemia. Laboratory may show elevated white blood cell and platelet counts. CASE REPORT: A 97-year-old female with a past history of atrial fibrillation presented with left-upper quadrant abdominal pain and fever since 20 days. Laboratory showed elevated white blood cell and platelet counts, increased C-reactive protein and lactate dehydrogenase. Both ultrasonographic and tomographic scans showed a large hypodense area of the spleen. The patient received intravenous antibiotic therapy, which led to significant clinical improvement with discharge 16 days after admission. DISCUSSION: The diagnosis of splenic infarction is based both on clinical presentation and imaging studies. Angio-computed tomography is the diagnostic procedure of choice. Ultrasonography and conventional radiology are useful in the differential diagnosis with other abdominal and thoracic diseases mimicking splenic infarction. In our case the management was conservative, because the patient was hemodynamically stable and antibiotic therapy could control the sepsis. Moreover, advanced age and poor cardiac and respiratory conditions contraindicated surgery. CONCLUSIONS: In our case splenic infarction was probably due to a thromboembolic event secondary to atrial fibrillation. In accordance with the literature, we suggest initial conservative therapy. Surgery is indicated only in the presence of complications.

Endoscopic sphincterotomy of the major duodenal papilla in acute relapsing pancreatitis associated with pancreas divisum: a case report.

We report a case of acute relapsing pancreatitis associated with pancreas divisum, who underwent major papilla sphincterotomy after failed minor papilla cannulation. Long-term results were satisfactory. The possible explanations of the efficacy of major papilla endoscopic resection in this particular case are discussed.

[Unusual cause of acute abdomen in adult patient: gallstone ileus]. / Insolita causa di addome acuto in paziente adulto: l'ileo biliare.

INTRODUCTION: Gallstone ileus is a rare complication of cholecystolithiasis. It causes 1-3% of the mechanical obstructions of the small bowel. It often affects patients between 63 and 85 years old. Pre-operative diagnosis is usually delayed 1-10 days because there is not a specific symptomatology. CASE REPORT: The authors report the case of a 50 year-old man with diagnosis of mechanical obstruction of the small bowel caused by a voluminous gallstone. Ileal occlusion was showed by CT. The patient underwent to one-stage emergency surgery with enterolithotomy, cholecystectomy and duodenal fistula repair. Patient's recovery was regular and he was discharged fourteen days after surgery. DISCUSSION: In our case gallstone ileus was diagnosed with a delay of 5 days. Ultrasonography was not able to show the gallbladder. Diagnosis was made by CT, which is the diagnostic gold standard. CONCLUSION: Patient's performance status influences surgical strategy. In our experience, the patient underwent one-stage surgery because he was considered at low risk. Instead staged procedure with enterolithotomy and delayed cholecystectomy and fistula repair, is performed only in patients at high risk.

Effects of either tibolone or continuous combined transdermal estradiol with medroxyprogesterone acetate on coagulatory factors and lipoprotein(a) in menopause.

BACKGROUND/AIM: The aim of this prospective controlled study was to compare the effects of two therapies for menopause on factor VII (FVII) and hemostatic variables. METHODS: Postmenopausal women were assigned to receive one of the following treatments: transdermal estradiol (TTS E2; 50 microg) combined in a continuous sequential regimen with oral medroxyprogesterone acetate (MPA; 10 mg/day for 12 days) (group A; n = 20), tibolone (2.5 mg/day) (group B; n = 21) or placebo (group C; n = 19). Sixty women completed the 1-year treatment and underwent follow-up examinations after 3, 6 and 12 months. RESULTS: TTS E2/MPA induced various changes in procoagulatory factors. At 12 months, fibrinogen, activated FVII (FVIIa) and coagulative FVII (FVIIc) had increased by 10.7, 12.9 and 3.7%, respectively. Among the fibrinolytic factors, plasminogen and alpha2-antiplasmin increased by 11.3 and 7.2%, respectively. Lipoprotein(a) [Lp(a)] and antithrombin III (ATIII) did not show any significant variation. Tibolone induced some changes toward a more homogeneous antithrombotic profile. Fibrinogen, FVIIa and FVIIc decreased significantly by 7.5, 8.1 and 21.3%, respectively. Plasminogen increased (by 11.8%) and Lp(a) decreased (by 28.4%). ATIII was unchanged with tibolone therapy. CONCLUSION: Our results show that tibolone induces a significant reduction in FVIIc and Lp(a) and a greater enhancement of factors promoting fibrinolysis than the TTS E2/MPA regimen.

Spontaneous umbilical endometriosis: a case report with one-year follow-up.

Umbilical endometriosis is a very rare disease. We report a case of spontaneous umbilical endometriosis in a 36-year old female. Endometriosis was suspected because of the presence of the typical cyclic bleeding and swelling. Abdominal CT excluded the presence of other endometriotic localizations. The umbilical mass was widely excised together with the umbilicus, fascia and peritoneum. The ensuing defect was primarily closed without using prosthetic mesh. Postoperative recovery was uneventful. Histological examination of the specimen showed the presence of endometrial glands with a stromal component, compatible with the diagnosis of endometriosis. At one-year follow-up the results of surgery were satisfactory with no sign of endometriosis recurrence and or parietal defect occurrence. We suggest that surgical excision should be wide in order to prevent local recurrence, and prosthetic materials should not be used to repair the ensuing umbilical defect.
