Sister Mary Joseph nodule.

Sister Mary Joseph nodule (SMJN) is a rare clinical finding in patients with metastatic adenocarcinoma. This is a case report of a 69-year-old man, who presented with a cutaneous element by his umbilicus at his GP. He was referred to a dermatologist, then a plastic surgeon. The element was a metastasis from adenocarcinoma originating from his caecum. It is important for doctors to know of SMJN as a rare presentation of metastatic cancer, and to clinically examine the patient for an abdominal starting point, when presented with a cutaneous tumour at the position of the umbilicus.

Atypical umbilical endometriosis: Microscopic and immunohistochemical characterization / Endometriosis atípica umbilical. Caracterización microscópica e inmunohistoquímica

Introduction: Atypical endometriosis is considered a precursor lesion to cancer associated with endometriosis. Two types of atypical endometriosis have been proposed: an architectural type with a higher risk of malignancy and a cytological type with a lower potential for malignancy. Main symptoms and/or clinical findings: A 37-year-old Caucasian woman presented with umbilical bleeding coinciding with menstruation. On physical examination, two small, bluish lesions were observed in the umbilical scar. Primary diagnosis: This clinical case is of interest because it describes a lesion of atypical architectural endometriosis located in the navel. Therapeutic interventions and results: The microscopic and immunohistochemical characteristics of the lesion were examined. The presence of nuclear stratification, hyperchromatism, and pleomorphism were observed as microscopic qualities. In terms of the immunohistochemical panel, the degree of cell proliferation was analyzed using Ki 67, BAF250a was used as the surrogate marker of ARID 1A, inflammation was assessed through COX, and estrogen and progesterone receptors were examined. The results showed increased cellular activity, the presence of inflammation, and no mutation of the ARID1a gene, with moderate cell proliferation. Conclusion: Umbilical endometriosis is rare, and while malignancy is infrequent, it is possible. For this reason, a complete anatomopathological study including an immunohistochemical panel should be performed to diagnose atypical endometriosis.(AU)

Introducción: La endometriosis atípica está considerada como una lesión precursora de cáncer asociado a endometriosis. Se han propuesto 2 tipos de endometriosis atípica, una arquitectural con mayor riesgo de malignización y otra citológica cuyo potencial de malignización es menor. Principales síntomas y/o hallazgos clínicos: Una mujer de 37 años caucásica consulta por sangrado catamenial umbilical. A la exploración física se observan 2 pequeñas lesiones umbilicales azuladas. Diagnóstico principal: Este caso clínico es interesante porque se describe una lesión de endometriosis atípica arquitectural localizada en el ombligo. Intervenciones terapéuticas y resultados: Se ha descrito sus características microscópicas e inmunohistoquímicas para caracterizarla. La presencia de estratificación nuclear, hipercromatismo y pleomorfismo como cualidades microscópicas y en cuanto al panel inmunohistoquímico se ha analizado el grado de proliferación celular mediante el Ki-67, BAF250a como el marcador subrogado del ARID1A, el grado de inflamación mediante COX y los receptores estrogénicos y gestagénicos. Los resultados demuestran que tiene una actividad celular aumentada, presencia de inflamación y no mutación del gen ARID1A con moderación proliferación celular. Conclusión: La endometriosis umbilical es poco frecuente y su malignización, aunque rara es posible. Por esta razón, se debería realizar un estudio anatomopatológico completo que incluya un panel inmunohistoquímico en aras de diagnosticar endometriosis atípica.(AU)

Ileal prolapse through patent omphalomesenteric duct in a two year-old boy: a case report.

BACKGROUND: Patent omphalomesenteric duct is one of the birth defects included in the spectrum of vitelline duct abnormalities. It is a rare anomaly with estimated prevalence of 0.13-0.2% in the general population. The most common presentation of patent vitelline duct is yellowish or mucoid type umbilical discharge which is usually noted in neonatal age or infancy. The main stay of diagnosis is clinical and outcome is favorable as long as timely surgical correction is offered. Here we present a 2 years old male child who presented with ileal prolapse through patent vitelline duct which is an exceptional mode of presentation of this pathology. CASE PRESENTATION: 2 years old Ethiopian male child who was noticed to have umbilical discharge since early infancy presented with protrusion of pinkish mass per the umbilicus of 4 h duration. He had no signs and symptoms of bowel obstruction. Abdominal examination revealed a prolapsed bowel which was viable via the umbilicus which was about 6 cm long. Otherwise, he had no abdominal tenderness or rigidity. He was explored with a smiley incision just above the umbilicus. The prolapsed bowel was reduced gently to the abdominal cavity. The tract of the Patent vitelline duct was identified and completely resected along with a wedge of ileum at its base. Primary repair of the ileal end where the tract was inserted was done in two layers and abdomen was closed in layers. The child had smooth post op course and was discharged on the 4th post-operative day. CONCLUSION: Prolapse of a bowel through the umbilicus is unusual presentation of a rare anomaly namely patent vitelline duct. This presentation warrants early surgical intervention before bowel ischemia issues. Hence, all clinicians dealing with children should be aware of this rare pathology so that urgent surgical management can be offered.

Is transumbilical laparoscopic-assisted appendectomy feasible for complicated appendicitis? A single-center experience.

PURPOSE: Transumbilical laparoscopic-assisted surgery (TULS) mixed benefits of laparoscopic and open surgeries. Transumbilical laparoscopic-assisted appendectomy (TULAA) is a well-known procedure, accepted and currently used by pediatric surgeons for treatment of uncomplicated appendicitis (UA). There is no current agreement in its use for the complicated appendiceal infections (CA). We reported our results using TULAA for both UA and CA. METHODS: We retrospectively collected TULAA performed between April 2017 and April 2022. Appendicitis were classified in UA and CA. We analyzed conversion rate, operative time, length of stay, surgical site infections (SSIs) rate, postoperative intra-abdominal abscess and costs. RESULTS: Over 5 years, 316 children underwent TULAA. Conversion rate was 3%. Mean age at surgery was 9.36 years (IQR 2-16). Forty-nine appendicitis were CA. Operative time and hospital stay was higher in CA than in UA group (38.33 vs. 60.73 min, p < 0.00001; 4 vs. 7 days, p < 0.00001). SSIs rate showed no statistically significant difference between two groups. Incidence of postoperative intra-abdominal collections was 11% in CA and 1% in UA. TULAA's cost was 192.07 €. CONCLUSION: In our series, TULAA seems to be safe, feasible and cost-effective for both uncomplicated and complicated appendicitis, with no disadvantage in terms of outcomes compared to what is reported in literature for CLS.

Patent vitellointestinal duct with ileal prolapse in a newborn: A case report and literature review.

RATIONALE: Patent vitellointestinal duct is the most common omphalomesenteric duct anomaly to present with symptoms. PATIENT CONCERNS: A 10-day-old child presented with increase in the size of a polypoidal lesion into a large, "Y"-shaped reddish, prolapsing lesion, discharging gaseous, and fecal matter at her umbilicus. A laparoscopic exploration was performed, followed by wedge resection and anastomosis. No complications occurred during postoperative follow-up. DIAGNOSES: A patent vitellointestinal duct with ileal prolapse. INTERVENTIONS: The resection of extended intraperitoneal intestinal tube was performed. OUTCOMES: During the follow-up 3 months after surgery, the umbilical cord of the child healed well after surgery. LESSONS: Timely surgical treatment can minimize the occurrence of complications, and the overall prognosis is good after surgery.

Reappraisal of the anatomical diversities of the pyramidalis muscle with their potential clinical applicability: cadaveric analysis.

INTRODUCTION: The present study examined the morphology and morphometric parameters of the pyramidalis muscle (PM) in detail with their potential applicability in making midline infra-umbilical incisions and biomechanics of the linea alba. METHODS: PM was examined in 51 formalin-fixed cadavers (36 males and 15 females), and based on the mode of insertion or the level of apex, the formation or shape of the muscle was classified into nine types (Mori's classification). RESULTS: Bilateral PM was more prevalent (39.21%) than unilateral (1.96%) (p = 0.001). All the cases showed side symmetry except one. Mori's type 7 (right PM is higher apex and the left PM with elongated origin) was the most common form. The mean length of PM in males and females was 4.51 ± 0.14 and 3.33 ± 0.12 cm on the right and 4.51 ± 0.11 and 3.26 ± 0.16 cm on the left side. The mean width of right-sided PMs in males and females was 1.90 ± 0.17 and 1.58 ± 0.13 cm and left-sided 1.88 ± 0.14 and 1.55 ± 0.38 cm. The mean of pyramidalis-pubo-umbilical index (PPI) in males and females was 32.82 ± 1.65 and 27.50 ± 1.08, respectively. The mean insertion angle was 24.56 ± 3.07 on right side and 23 ± 2.03 on the left side (p = 0.03). Male predominance existed on right- and left-sided PM length (p < 0.001 and p < 0.001), width (p = 0.001) and PPI (p = 0.001). The strong positive correlation (r = 0.83) between length and width indicates a symmetrical muscle augmentation in the two dimensions. CONCLUSION: PM is an inconsistent anatomical structure with persistent morphology. The level and angle of insertion into the linea are crucial in the biomechanics of linea alba. PPI, determining the termination level would be useful to surgeons making midline infra-umbilical incisions.

Prolonged cord separation in a newborn: a rare case of an unusual epithelialised umbilical cord.

A female full-term neonate, accompanied by her parents, was referred to the paediatric surgery department on the day of after birth. She presented with a 9 cm length pathological umbilical cord, of which the first 7 cm was red and wet, with ulceration, necrosis and healing areas. The patient never had a fever. Abdominal palpation showed no umbilical hernia and abdominal Doppler ultrasound was normal. After several days of disinfection, by biseptine antiseptic solution, and a monthly follow-up, most of the umbilical cord fell out. It only remained a 4 cm length navel consisting of 2 cm of excessive skin and 2 cm of mucous tissue. The lesion was surgically excised at 6 months old. The patient was discharged on postoperative day 1. The results of the histology confirmed the diagnosis of an epithelialised umbilical cord. The 1-month follow-up was uneventful.

Indications, outcomes, and complications of neoumbilical reconstruction: A systematic review.

BACKGROUND AND OBJECTIVES: Neoumbilicoplasty aims to reconstruct an aesthetically pleasing new umbilicus following agenesis, malignancy, anatomical distortion, or umbilicus loss. Despite the wide variety of surgical techniques described, literature is scarce when it comes to standardized categorization of these as well as the clear definition of patients' selections, specific indications, final outcomes, and possible complications. According to available literature, this work aims to evaluate different surgical approaches, and correlate them to specific surgical needs, to simplify the surgical choice and patient management. METHODS: A systematic review was performed in December 2020 in PubMed, Web of Science, and MedLine Ovid databases according to the PRISMA guidelines. RESULTS: A total of 41 studies and 588 patients were finally included. On the basis of the evidence of the literature collected, we divided the studies into four groups according to the neoumbilicoplasty techniques: single suture or purse-string suture, single flap, multiple flap, and skin graft. Patients' surgical comorbidities, neoumbilicoplasty indications, and aesthetic and surgical outcomes were investigated. Direct suture and single and multiple flap techniques assured overall, satisfactory cosmetic outcomes with a low rate of surgical complications. Whereas suture-only techniques were chosen mostly by general surgeons/urologists in laparoscopic surgery, the single flap was the preferred method to reconstruct the umbilicus in open abdominal surgery or combined abdominoplasty with herniorrhaphy. Multiple flap and skin grafts were adopted in abdominoplasty-related umbilicus reconstruction, although the latter option showed impactful aesthetic and surgical complications. CONCLUSIONS: Umbilicoplasty can assure generally pleasant aesthetic outcomes with relatively low complication rates. Indications for specific techniques correspond to different patient populations and surgical scenarios.

Quality of life amongst patients with diverting umbilical stomas in rectal surgery: a single centre prospective randomized controlled pilot study.

BACKGROUND: The umbilical stoma (umbistoma) has been proposed as a viable alternative site for a temporary defunctioning stoma. Suggested advantages of the umbistoma include decreased number of surgical incisions required, improved cosmesis and ease of reversal surgery. This study aimed to assess the patient experience of umbilical loop ileostomies in rectal surgery, with the primary outcome being patient reported quality of life (QoL). METHODS: A total of 20 patients undergoing laparoscopic rectal cancer surgery were randomly allocated to have a defunctioning ileostomy at a conventional site (right iliac fossa) or at the umbilicus. Patient-reported QoL was assessed at 6 weeks using the Stoma-QoL questionnaire. Secondary outcomes were number of stomas reversed, length of time awaiting stoma reversal surgery, duration of operative time for stoma reversal, length of hospital stay following stoma reversal and rate of parastomal or post reversal incisional hernias. RESULTS: Patients who had an umbilical stoma scored significantly lower on the Stoma-QoL questionnaire compared to the conventional group, particularly on questions regarding feelings of tiredness, body insecurity and anxiety. No significant differences were observed between the two groups in relation to secondary outcomes. CONCLUSION: There may be potential disadvantages to the umbilical stoma with negative impacts on body image and subsequent increased social anxiety. Patient selection and adequate counselling will be important when considering an umbilical stoma. Further larger scale prospective studies are required to further validate the feasibility and longer-term safety of umbilical stomas in both clinical outcomes as well as patient QoL.

Intraoperative and Postoperative Outcomes of Modified Bidirectional Intra-Umbilical Incision versus Infra-Umbilical Incision for Direct Trocar Insertion in Gynaecological Laparoscopy: A randomised controlled trial.

Objectives: This study aimed to describe a modified, curved, deep, bidirectional, intra-umbilical, vertical incision for primary trocar insertion and prospectively compare its intraoperative and postoperative outcomes with an infra-umbilical incision in gynaecologic laparoscopy. Methods: Between August 2019 and March 2021, 110 patients subjected to the direct trocar insertion technique for laparoscopic intervention were classified into two groups. Group A comprised 55 cases of infra-umbilical incision, whereas group B comprised 55 cases of a modified, curved, longitudinal, deep, bidirectional, intra-umbilical incision. Afterwards, intraoperative and postoperative assessments were performed. Results: The increase in the numbers of parity, gravidity and previous caesarean sections was found to be statistically significant; a smaller number of infertility complaints were observed in group B. Similarly, group B expressed a statistically significant less peri-trocar CO2 leakage (46 [83.6%] patients versus 28 [50.9%] patients) and more tightness of the primary portal entry (45 [81.8%] patients versus 30 [54.5%] patients) when compared to group A throughout the whole operation. After a one-month follow-up, a statistically significant (P = 0.029) decrease in the Observer Scar Assessment Scale and Patient Scar Assessment Scale scores in group B (10.4 ± 4.2 and 11.8 ± 4.3, respectively), demonstrating better cosmoses when compared to group A (13.3 ± 5.7 and 16.0 ± 6.8, respectively). Conclusion: Performing a modified, curved, deep, bidirectional, intra-umbilical, vertical incision for the insertion of a primary laparoscopic trocar (i.e. Darwish laparoscopic entry) is a simple and fast step that results in the elimination of intraoperative gas leakage and trocar slippage without the need for any additional sutures. Aesthetically, it results in a better scar with satisfactory cosmoses when compared to an infra-umbilical incision.

Timing umbilical therapy in treatment of neurogenic bladder after spinal cord injury based on midnight-noon and ebb-flow doctrine: a randomized controlled trial. / åŸºäºŽå­åˆæµæ³¨ç†è®ºæ‹©æ—¶è„ç–—æ²»ç–—è„Šé«“æŸä¼¤åŽç¥žç»æºæ€§è†€èƒ±ï¼šéšæœºå¯¹ç §è¯•éªŒ.

OBJECTIVES: To observe the clinical efficacy of timing umbilical therapy for neurogenic bladder after spinal cord injury based on the midnight-noon and ebb-flow doctrine. METHODS: Sixty patients with neurogenic bladder after spinal cord injury were randomly divided into a trial group and a control group, with 30 patients in each group. In the trial group, based on the midnight-noon and ebb-flow doctrine, umbilical therapy was given at the time zone, 15:00 to 17:00. In the control group, umbilical therapy was delivered at any time zones except the period 15:00 to 17:00. The herbal plaster was remained on the umbilicus for 4 h each time, once daily. One course of treatment was composed of 2 weeks and the treatment lasted 4 weeks. Before and after treatment, the urodynamic indexes (maximum urinary flow rate [Qmax], maximum detrusor pressure [Pdet-max], residual urine volume [RUV]), voiding diary (average daily number of voiding, average daily number of leakage, average daily voided volume), neurogenic bladder symptom score (NBSS), the score of urinary symptom distress scale (USDS) and the score of World Health Organization quality of life assessment-BREF (WHOQOL-BREF) were compared between the two groups; and the clinical efficacy of the two groups was assessed. RESULTS: After treatment, Qmax, Pdet-max, the average daily voided volume and the scores of WHOQOL-BREF were increased (P<0.05); and RUV, the average daily number of voiding, the average daily number of leakage, NBSS and the scores of USDS were all reduced (P<0.05) in comparison with those before treatment in the two groups. When compared with those in the control group, Qmax, Pdet-max, the average daily voided volume and the score of WHOQOL-BREF were all higher (P<0.05); and RUV, the average daily number of voiding, the average daily number of leakage, NBSS and the score of USDS were lower (P<0.05) in the trial group. The total effective rate was 96.7% (29/30) in the trial group, higher than that (76.7%, 23/30) in the control group (P<0.05). CONCLUSIONS: Timing umbilical therapy, based on the midnight-noon and ebb-flow doctrine, effectively relieves the symptoms of dysuria and improves the quality of life in patients with neurogenic bladder after spinal cord injury.

Vascular perforation of umbilical venous catheter and awaiting it to be shallow.

The patient was a boy born at 23 weeks and 0 days of gestation weighed 401 g at birth. For treatment, an umbilical venous catheter was placed but the catheter perforated a blood vessel. We thought that prompt removal of the catheter would lead to massive bleeding, so we kept the catheter in place at the umbilicus, waited for weight gain, and removed it after confirming that the catheter tip had spontaneously become shallow and was in the umbilical vein. This procedure allowed us to handle the patient without major problems.

[Umbilical pilonidal sinus - a rare disease?] / Pilonidalsinus i naveln ­ ovanlig diagnos eller stort mörkertal?

Umbilical pilonidal sinus is a rare diagnosis which is characterized by an inflammatory granulomatous reaction to hair shafts penetrating the epidermis. It is most often seen in adolescent male with a hairy abdomen. The patients often present with a history of pain and umbilical discharge. Conservative treatment with hair extraction and personal hygiene is prioritized and surgery is only recommended in recurrent cases. Here one such case is presented, which was resistant to conservative treatment and where surgical excision and primary repair was indicated. No recurrence was observed 6 months postoperatively.

[Villar's nodule]. / Nodule de Villar.

Umbilical endometriosis is a rare manifestation, most often isolated, of endometriosis, accounting for 0,5-1 % of all cases. It can be primary or secondary following surgery. It usually presents as a solid, skin-colored, red or purple-black nodule, frequently associated with pain and/or perimenstrual bleeding. Because it has a potential for malignant transformation, the gold standard of treatment is surgical removal.

L'endométriose ombilicale, ou nodule de Villar, est une manifestation rare et le plus souvent isolée d'endométriose, survenant dans 0,5 à 1 % des cas. Elle peut être primaire ou secondaire à une intervention chirurgicale. Elle se manifeste habituellement par un nodule ferme, de couleur chair, rouge ou violet-noir, fréquemment associé à des douleurs et/ou des saignements péri-menstruels. Il existe un risque potentiel de transformation maligne, raison pour laquelle le traitement de première intention est l'exérèse chirurgicale.
