Transgenic Res 2021; 30:663-674. [PMID: 34304368 DOI: 10.1007/s11248-021-00275-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Accepted: 07/19/2021] [Indexed: 11/30/2022]
Abstract
Herein, we investigate the high incidence of umbilical hernia and tippy-toe standing and their underlying changes in gene expression and proliferation in myostatin knockout (MSTN-/-) pigs. Thirty-six male MSTN-/- pigs were generated by somatic cell nuclear transfer (SCNT). These pigs presented a considerably high incidence of tippy-toe standing and umbilical hernia (69.4% and 61.1%, respectively). The tendon to body weight ratio was significantly lower than wild-type pigs (0.202 ± 0.017 vs 0.250 ± 0.004, respectively). The crimp length of the MSTN-/- tendon was significantly longer than that of wild-type pigs. The expression of MSTN and the activin type IIB (ACVR2B) was detected in the tendon and linea alba of MSTN-/- pigs. MSTN treatment significantly increased the phosphorylation of Smad2/3 in both tendon and linea alba fibroblasts. Type I collagen (Col1A) and Scleraxis (Scx) expression levels in the tendon and linea alba of MSTN-/- pigs were significantly lower than those in wild-type in vivo, whereas and cyclin-dependent kinase inhibitor 1 (p21) expression levels were higher. Treatment of tendon and linea alba fibroblasts with recombinant MSTN increased Col1A and Scx and decreased p21 expression in vivo. Moreover, there was a significant increase in fibroblast proliferation after treatment. The results indicated that MSTN regulates collagen expression and proliferation in tendon and linea alba fibroblasts; thus, MSTN deficiency causes collagen-related pathological features in MSTN-/- pigs. Hence, MSTN could be used as a therapeutic target for treating UH and tendon abnormalities.

Abstract
PURPOSE Midline abdominal wall hernia repair is among the most common surgical interventions performed worldwide. However, the optimal surgical technique remains controversial. To overcome the disadvantages of both open and transabdominal procedures, we developed a totally endoscopic preperitoneal approach (eTPA) with placement of a large mesh. METHODS From December 2019 to October 2020, 20 consecutive patients with small to medium-sized midline ventral hernias underwent repair using a completely preperitoneal subxiphoid top-down approach. The preperitoneal space was entered directly below the xiphoid, and careful endoscopic development of the plane between the peritoneum and posterior sheath of the rectus fascia was then performed behind the linea alba. The hernia sac and its contents were identified and reduced. The hernia defect was closed with sutures, and a mesh with an adequate high defect: mesh ratio was placed in the newly created preperitoneal space. RESULTS Twenty patients were enrolled in this study, including 14 with primary umbilical hernias, 4 with primary epigastric hernias, and 2 with recurrent umbilical hernias. 15 patients suffered from a mild concomitant diastasis recti. All operations were successfully completed without conversion to open repair. The mean operative time was 105.3 min (range, 60-220 min). Postoperative pain was mild, and the mean visual analog scale score for pain was 1.8 on the first postoperative day. The average postoperative hospital stay was 1.8 days (range, 1-4 days). One patient developed a minor postoperative seroma, but it had no adverse impact on the final outcome. No patients developed recurrence during the 3- to 10-month follow-up period. CONCLUSIONS The subxiphoid top-down totally endoscopic preperitoneal approach (eTPA) technique is feasible and effective. It may become a valuable alternative for the treatment of primary small- (defect size < 2 cm) and medium-sized (2-4 cm) midline ventral hernias, particularly in presence of a concomitant diastasis recti.

Management of epigastric, umbilical, spigelian and small incisional hernia as a day case procedure: results of long-term follow-up after open preperitoneal flat mesh technique. Hernia 2021; 25:1095-1101. [PMID: 34165648 DOI: 10.1007/s10029-021-02446-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Accepted: 06/09/2021] [Indexed: 01/19/2023]
Abstract
PURPOSE To investigate short and long-term outcome after the open preperitoneal flat mesh technique (OPFMT) for umbilical, epigastric, spigelian, small incisional and "port-site" hernia performed as a day case procedure. METHODS We retrospectively analyzed records of patients who underwent OPFMT for umbilical, epigastric, Spigelian, small incisional and "port-site" hernia in ambulatory settings between 2004 and 2020 at Clinical Center of Serbia. Demographic and clinical characteristics, operative data and postoperative complications were compared between the groups. Univariate and multivariate analyses were performed to identify predictive factors for mesh infection and recurrence. RESULTS Overall, 476 patients were divided according to the type of hernia. Early postoperative complications were similar in all study groups. Mesh infection, chronic pain and recurrence were different between groups (p = 0.013, p = 0.019 and p = 0.011, respectively). Overall recurrence rate after OPFMT was 2.5%. Hernia defect, hematoma and length of postoperative stay at the Day Surgery Unit were identified as potential predictors of mesh infection (Odds ratio 6.449, 22.143 and 1.546, respectively; p = 0.027, p = 0.011 and p = 0.038, respectively) while mesh infection was the only potential predictor of recurrence in univariate analysis. Hematoma was an independent predictor of recurrence (Odds ratio 27.068; 95% Confidence interval 2.355-311.073; p = 0.008). CONCLUSION The OPFMT performed under local anesthesia as a day case procedure is a safe technique associated with favorable long-term outcome. Hematoma is an independent predictor of mesh infection occurrence.

Abstract
Introduction and importance A Littre's hernia (LH) is defined by the presence of Meckel's diverticulum (MD) in any kind of hernia sac. Preoperative diagnosis of LH is a challenge because of its rarity and the absence of specific radiological findings and clinical presentation. Surgery is the appropriate treatment of complicated LH that is an extremely rare condition with approximately 50 cases reported in the literature over the past 300 years. Case presentation A 46-year-old Caucasian female was admitted to the Emergency Department with a two-day history of abdominal pain. Physical examination revealed an irreducible and painfull mass in umbilical region. Abdominal computed tomography scan showed the protrusion of greater omentum and small bowel loop through the umbilical ring. Laboratory tests were unremarkable. After diagnosis of strangulated umbilical hernia, the patient underwent exploratory laparotomy: the irreducible umbilical hernial sac was opened with presence of incarcerated and strangulated omentum and uncomplicated MD. Resection of incarcerated and ischemic greater omentum alone was performed. The postoperative course of patient was uneventful. Clinical discussion Meckel's diverticulum (MD) is a vestigial remnant of the omphalomesenteric duct, representing the most common congenital malformation of the gastrointestinal tract. Preoperative diagnosis of LH is very difficult and surgery represents the correct treatment of complicated LH. Conclusion LH represents an extremely rare complication of MD difficult to diagnose and suspect because of the lack of specific radiological findings and clinical presentation. Surgery represents the appropriate treatment of abdominal wall hernias and complicated MD. A Littre's hernia (LH) is defined by the presence of Meckel's diverticulum (MD) in any kind of hernia sac. LH is an extremely rare complication of MD and its preoperative diagnosis is very difficult. Surgery represents the appropriate treatment of abdominal wall hernias and complicated MD. Routine resection of uncomplicated MD is not advised and it should be based on identified MD’ s risk factors.

Abstract
Background: Both umbilical and epigastric hernias may be associated with rectus muscle divarication. In such cases, isolated repair of combined hernia defects can have high recurrence rates and poorer cosmetic outcomes, thus the repair of both pathologies ought to be favored. The goal of the study below is to provide detailed technical aspects of the endoscopic retro-rectus mesh repair. Methods: We chose a group of 16 patients who underwent the repair of ventral hernias associated with both primary and incisional rectus diastasis, using the extended-view of a totally extraperitoneal Rives-Stoppa repair (eRives) technique. All defects were < 6 cm in width. Our outcome measures perioperative complications and early recurrences. Results: The approach used in our study has led to zero cases of perioperative complications and only one early recurrence. Conclusions: We believe that the e-Rives repair is the optimal approach for ventral hernias associated with diastasis recti. This technique additionally produces favorable cosmetic outcomes that granted our results a well-deserved recognition in the medical literature.

Abstract
BACKGROUND The optimal anesthesia modality for umbilical hernia repair is unclear. We hypothesized that using local rather than general anesthesia would be associated with improved outcomes, especially for frail patients. METHODS We utilized the 1998-2018 Veterans Affairs Surgical Quality Improvement Program to identify patients who underwent elective, open umbilical hernia repair under general or local anesthesia. We used the Risk Analysis Index to measure frailty. Outcomes included complications and operative time. RESULTS There were 4958 Veterans (13%) whose hernias were repaired under local anesthesia. Compared to general anesthesia, local was associated with a 12%-24% faster operative time for all patients, and an 86% lower (OR 0.14, 95%CI 0.03-0.72) complication rate for frail patients. CONCLUSIONS Local anesthesia may reduce the operative time for all patients and complications for frail patients having umbilical hernia repair.

Abstract
PURPOSE We sought to estimate the prevalence, incidence, and timing of surgery for elective and non-elective hernia repairs. METHODS We performed a retrospective cohort study, abstracting data on children < 18 years from the 2005-2014 DoD Military Health System Data Repository, which includes > 3 million dependents of U.S. Armed Services members. Our primary outcome was initial hernia repair (inguinal, umbilical, ventral, or femoral), stratified by elective versus non-elective repair and by age. We calculated prevalence, incidence rate, and time from diagnosis to repair. RESULTS 19,398 children underwent hernia repair (12,220 inguinal, 5761 umbilical, 1373 ventral, 44 femoral). Prevalence of non-elective repairs ranged from 6% (umbilical) to 22% (ventral). Incidence rates of elective repairs ranged from 0.03 [95% CI: 0.02-0.04] (femoral) to 8.92 [95% CI: 8.76-9.09] (inguinal) per 10,000 person-years, while incidence rates of non-elective repairs ranged from 0.005 [95% CI: 0.002-0.01] (femoral) to 0.68 [95% CI: 0.64-0.73] (inguinal) per 10,000 person-years. Inguinal (median = 20, interquartile range [IQR] = 0-46 days), ventral (median = 23, IQR = 5-62 days), and femoral hernias (median = 0, IQR = 0-12 days) were repaired more promptly and with less variation than umbilical hernias (median = 66, IQR = 23-422 days). CONCLUSIONS These data describe the burden of hernia repair in the U.S. The large variation in time between diagnosis and repair by hernia type identifies an important area of research to understand mechanisms underlying such heterogeneity and determine the ideal timing for repair. LEVEL OF EVIDENCE Prognosis study II.

Abstract
Umbilical hernia and other conditions clinically evident as umbilical outpouchings (UOs) affect the welfare and economy in Danish pig production. The objectives of the current study were to characterize the associations between 1) time of detection of the UOs and the odds of dying before scheduled slaughter; 2) time of death, irrespective of the cause, and clinical signs of the UOs, i.e. general condition, size, reducibility, form and skin-color of the UOs; and 3) occurrence of wounds on the UOs and clinical signs: general condition, size, reducibility, form and skin-color. A cohort of Danish conventional pigs with UOs (n = 255) were followed from the detection of an UO until spontaneous death, euthanization or slaughter of the pig. The pigs were clinically examined once a month, and when pigs with an UO died spontaneously, were euthanized or slaughtered, the causes and date of death were recorded. The effects of the clinical manifestations on overall survival were assessed using a Cox proportional hazards model. In total 57 % of the pigs died spontaneously or were euthanized before slaughter. The median age of spontaneous death or euthanasia was 85 days. The UOs were detected at different ages, with half of the pigs (52 %) detected in the farrowing section. No significant association was found between death before scheduled slaughter and the time of detection. Three different clinical manifestations were found to have a prognostic value for overall survival until slaughter, i.e. skin-color of the UO, a general condition of the pig and the size of the UO. An interaction was present between the size and the skin-color of the UO. Wounds on the UO were the most frequent complication resulting in euthanasia (37 %). The odds for developing a wound on the UO were higher for pigs in a general bad condition compared to pigs in a good condition (OR, 5.4; 95 % CL 2.5-11.3), and for pigs with an UO large in size compared to pigs with a small UO (OR, 4.8; 95 % CL 3.0-7.5). The identification of prognostic clinical signs in pigs with an UO is useful in the assessment and decision-making in relation to the future prospects of pigs with UOs.

Abstract
Umbilical hernia, one of the most frequent pathologies in pediatric surgical practice, is usually corrected with a relatively simple intervention, except in cases where there is a major defect, also called proboscoid hernia. We present a case report of a 20-month male patient that underwent surgical intervention of a giant umbilical hernia with the "Lazy-M and Omega" flap novel surgical technique. This technique has to be taken into account in surgical planning, since it is simple and easily reproducible.

Abstract
Primary (umbilical, epigastric hernias) and secondary (incisional hernias) ventral hernias are among the most common surgical indications in general and visceral surgery. The defect width and defect localization have a considerable impact on treatment decision-making and outcomes. Therefore, preoperative computed tomography (CT) examination is increasingly recommended particularly for larger incisional hernias. Despite the good results reported in meta-analyses and registry analyses, in recent years there has been a marked trend away from the intraperitoneal onlay mesh (IPOM) technique as severe complications have repeatedly been reported. To continue to benefit from the advantages conferred by a minimally invasive access route with fewer wound complications, a myriad of new techniques with small incisions or endoscopic access have been developed. These involve mesh placement in the sublay/retromuscular/preperitoneal position. This provides a relatively differentiated tailored approach.

Abstract
PURPOSE The primary goal of this study was to determine the incidence of occult paraumbilical hernias during open primary umbilical hernia repair. The secondary objective was to further characterize the clinical features of these patients and hernias. METHODS This was a retrospective chart review of patients undergoing primary umbilical hernia repair at Shouldice Hospital, from 2007 to 2017. Inclusion criteria were utilized to elucidate patients, where a concomitant occult paraumbilical hernia was found. Descriptive statistics were used throughout. RESULTS 5850 patients underwent primary umbilical hernia repair, 459 (7.85%) patients had concomitant primary umbilical and paraumbilical hernias. There was a preoperative suspicion/diagnosis of a paraumbilical hernia in 166 (2.8%) of these patients. In 293 (5.01%) patients who had open primary umbilical hernia repair, at least one associated occult paraumbilical defect was found during surgery. Most of umbilical and concomitant occult paraumbilical hernias were small and medium size defects. The great majority of the reported occult paraumbilical hernias were found in the supraumbilical position at a distance of 3 cm or less from the top of the umbilical defect. CONCLUSION The incidence of concomitant occult paraumbilical hernias in patients mildly overweight undergoing primary umbilical hernia repair is 5.01%, relevant to surgical decision-making. Since the great majority of these paraumbilical defects are superior to the umbilical defect, an adequate incision and dissection for at least 3 cm above the umbilical hernia may reduce the number of missed concomitant hernias and result in less presumed recurrences.

Abstract
Purpose To establish optimal management of patients with an umbilical hernia complicated by liver cirrhosis and ascites. Methods Patients with an umbilical hernia and liver cirrhosis and ascites were randomly assigned to receive either elective repair or conservative treatment. The primary endpoint was overall morbidity related to the umbilical hernia or its treatment after 24 months of follow-up. Secondary endpoints included the severity of these hernia-related complications, quality of life, and cumulative hernia recurrence rate. Results Thirty-four patients were included in the study. Sixteen patients were randomly assigned to elective repair and 18 to conservative treatment. After 24 months, 8 patients (50%) assigned to elective repair compared to 14 patients (77.8%) assigned to conservative treatment had a complication related to the umbilical hernia or its repair. A recurrent hernia was reported in 16.7% of patients who underwent repair. For the secondary endpoint, quality of life through the physical (PCS) and mental component score (MCS) showed no significant differences between groups at 12 months of follow-up (mean difference PCS 11.95, 95% CI − 0.87 to 24.77; MCS 10.04, 95% CI − 2.78 to 22.86). Conclusion This trial could not show a relevant difference in overall morbidity after 24 months of follow-up in favor of elective umbilical hernia repair, because of the limited number of patients included. However, elective repair of umbilical hernia in patients with liver cirrhosis and ascites appears feasible, nudging its implementation into daily practice further, particularly for patients experiencing complaints.

Abstract
INTRODUCTION Based on meta-analyses and registry data, the European Hernia Society and the Americas Hernia Society have published guidelines for the treatment of umbilical hernias. These recommend that umbilical hernia should generally be treated by placing a non-absorbable (permanent) flat mesh into the preperitoneal space with an overlap of the hernia defect of 3 cm. Suture repair should only be considered for small hernia defects of less than 1 cm. Hence, the use of a mesh in general is subject to controversial debate particularly for small (< 2 cm) umbilical hernias. This analysis of data from the Herniamed Registry now presents data on the treatment of small (< 2 cm) umbilical hernias over the past 10 years. METHODS Herniamed is an Internet-based hernia registry in which hospitals and surgical centers in Germany, Austria and Switzerland can voluntarily enter data on their routine hernia operations. Between 2010 and 2019, data were entered into the Herniamed Registry by 737 hospitals/surgery centers on a total of 111,765 patients with primary elective umbilical hernia repair. The prospective data were analyzed retrospectively for each year and statistically compared. Due to a higher number of cases, the years 2013 and 2019 were compared for the perioperative outcome and the years 2013 and 2018 for 1-year follow-up. Fisher's exact test was applied for unadjusted analyses between the years, using a significance level of alpha = 5%. For post hoc tests of single categories, a Bonferroni adjustment for multiple testing was implemented. RESULTS A mesh technique was used to treat 45.4% of all umbilical hernias. The proportion of small (< 2 cm) umbilical hernias in the total collective of umbilical hernias was 55.6%. Suture repair was used consistently over the 10-year period to treat around 75% of all small (< 2 cm) umbilical hernias. Preperitoneal mesh placement as recommended in the guidelines was used only in 1.8% of cases. Between 2013 and 2019, stable values of 2 and 0.7% were observed for the postoperative complications and complication-related reoperations, respectively, with no relevant effect identified for the surgical technique. At 1-year follow-up, significantly higher rates of pain at rest (2.6 vs. 3.3), pain on exertion (5.7 vs. 6.6), and recurrences (1.3 vs. 1.8) (all p < 0.05) were identified for 2018 compared with 2013. CONCLUSIONS A suture technique is still used to treat 75% of patients with small (< 2 cm) umbilical hernias. The pain and recurrence rates are significantly less favorable for 2018 compared with 2013.

Abstract
The use of robot-assisted minimally invasive surgery in ventral/incisional hernia repair has increased exponentially in recent years. This increase is probably related to the advantages of robotic surgery, among which are better visualization, the implementation of articulated instruments and better ergonomics for the surgeon. The TARUP (Robotic Transabdominal Retromuscular Umbilical Prosthetic Hernia Repair) technique combines the benefits of minimally invasive surgery, in terms of less wound-related morbidity, also allowing the placement of a mesh in a retromuscular position facilitated by the use of the robotic platform.

Abstract
BACKGROUND Patients presenting for evaluation of umbilical and epigastric hernias are often found to have diastasis recti (DR). As isolated hernia repair in these patients may be associated with higher rates of recurrence, prior international publications have described a prefascial mesh repair in combination with anterior plication of DR. We present our initial United States (US) experience with a SubCutaneous OnLay endoscopic Approach (SCOLA) to address these concurrent pathologies in a single hybrid procedure. METHODS Between July 2018 and December 2019, a prospective cohort of 16 patients underwent the SCOLA procedure. Subcutaneous dissection was carried out from the suprapubic region superiorly to the xiphoid process and laterally to the linea semilunaris. Hernia contents were reduced and defects were incorporated into anterior DR plication, which was performed with running barbed suture. Onlay mesh was placed to cover the entire dissected space, and subcutaneous drains were placed. Three separate attendings performed cases with one supervising attending for standard technique. RESULTS Of 16 patients, 14 (87.5%) were female. The mean age was 45.7 (11.9) years; mean BMI was 29.0 (3.6) kg/m2. The mean hernia defect size was 1.9 (0.7) cm. Mean operative time was 146 (46.3) minutes; two (15%) cases were performed robotically. The mean follow-up time was approximately two months (63 days). Three (18.8%) patients developed seroma, one (6.3%) patient developed an infected seroma, and two (12.5%) patients developed hernia recurrence. CONCLUSIONS SCOLA technique is shown to be a safe and effective approach for patients presenting with small midline ventral hernias and concomitant DR. Our preliminary US data demonstrates higher rates of post-operative complication in patients with higher BMI, which suggests that patient selection and pre-operative counseling is essential to achieve better technical outcomes in our patient population.

Abstract
Highlighting the possibility of concurrent double pathology in acute care surgery. Conflicting clinical features can delay the diagnosis and alter the management. High index od suspicious is paramount in the interpretation of patient findings. In comorbid patients, we can expand the indication of radiology in small ventral hernia. One-stage colonic resection is still feasible in acute colonic obstruction even in.
Introduction Obstructed colon cancer is not an uncommon surgical emergency. Many other surgical diseases may overlap their presenting symptoms. This paper aims to report a colon cancer case with delayed diagnosis due to a long-standing para-umbilical hernia (PUH). Case report 60-year-old female patient presented to our emergency department (ED) with an obstructed PUH. The patient underwent watchful conservative management many times before due to associated comorbidities. This history of recurrent intestinal obstruction and incomplete regain of regular bowel habits after every hospital admission raises the possibility for concealed pathology. Further investigations, including computed tomography (CT), revealed a suspicion of an obstructed malignant mass at the colon's splenic flexure accompanied with complete bowel obstruction. The patient and their family consulted for exploratory laparotomy and the possibility of stoma formation. The intra-operative finding was constant with a small ventral defect, and a dilated bowel loops up to a left colon transition zone. We achieved left hemicolectomy with a primary anastomosis after intra-operative bowel lavage. The postoperative period was uneventfully, and the patient was discharged home after seven days of admission. Follow up in the outpatient surgical clinic for three months revealed no recordable complications. The patient had transferred to the oncology center for the completion of adjuvant therapy. Discussion This case had a small PUH with recurrent obstruction. The delay in its management was due to the patient's comorbidities. However, the incomplete resolution of patient symptoms during watchful oversight increases the likelihood of another hidden pathology that required further investigation. We expanded CT indication in such patients to find the exact cause of patient symptoms, especially chronic constipation and incomplete recovery after every admission. While concurrent pathology is the norm in elective surgery and can be dealt with safely, in non-elective surgery, a thorough search about the patient's exact complaints is mandatory to decrease morbidity and mortality rates. Conclusion In the same patient, both colon cancer and abdominal wall hernias can produce conflicting symptoms and delay diagnosis. However, with a high index of suspicion and correlation of patient symptoms, can be safely managed without morbidity.

Contemporary practice and perceptions surrounding the management of asymptomatic umbilical hernias in children: A survey of the American Pediatric Surgical Association. J Pediatr Surg 2020; 55:2052-2057. [PMID: 32122639 DOI: 10.1016/j.jpedsurg.2020.02.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Revised: 02/01/2020] [Accepted: 02/06/2020] [Indexed: 11/21/2022]
Abstract
PURPOSE To explore variation in perceptions regarding the natural history of asymptomatic umbilical hernias, and to characterize the influence of clinical and nonclinical factors on decision-making surrounding timing of repair. METHODS This was a survey of the American Pediatric Surgical Association. Branching logic and Likert scale questions were used to explore perceptions surrounding natural history (risk of complications and likelihood of spontaneous closure), preferred age for repair, and influence of anatomic, caregiver, sociodemographic, and biological factors on operative timing. RESULTS 44% of members completed the survey (371/846). The most common age respondents would consider elective repair was 3 years (37%), although the majority preferred to wait until 4 or 5 years (54%). Most respondents estimated a <1% risk of complications for unrepaired defects, and much greater variability was found in the perceived likelihood of spontaneous closure over time. Decision-making surrounding operative timing was most influenced by anatomic factors (larger defects, proboscoid changes, and interval growth) and parental anxiety surrounding need for emergency surgery, cosmesis, and stigma of parental neglect. CONCLUSION Practice and perceptions surrounding management of asymptomatic umbilical hernias vary widely. More robust epidemiological data are needed to define the likelihood of spontaneous closure in the context of age and physical exam findings. Collaborative efforts between surgeons and referring providers are also needed to optimize management of caregiver anxiety and expectations surrounding need for surgical referral and repair.

Abstract
Background Littre's hernia containing Meckel's diverticulum is an extremely rare disease. We report an adult case of two-stage laparoscopic surgery for incarceration of Meckel's diverticulum in an umbilical hernia. Case presentation The case involved a 23-year-old, severely obese man with BMI 36.5 kg/m2. After experiencing effusion from the umbilicus for 2 months, and was referred from a local dermatologist. We diagnosed an infected urachal remnant, and antibiotic therapy was performed first. Surgery was planned for after the infection disappeared. During follow-up, effusion from the umbilicus took on an intestinal fluid-like character, so we diagnosed small intestinal cutaneous fistula and performed surgery. Under laparoscopy, we found a Meckel's diverticulum incarcerated in an umbilical hernia. The diverticulum was resected first, and the incarceration was released. The umbilicus was infected, so we planned repair of the umbilical hernia in a second surgery. The postoperative course was uneventful and the patient was discharged on postoperative day 5. One month after the initial operation, we confirmed that there were no signs of infection, and performed umbilical hernia repair using the laparoscopic intraperitoneal onlay mesh (IPOM) repair. Postoperative progress was uneventful and he was discharged on postoperative day 4. No recurrence or infection was observed until 8 months postoperatively. Conclusions We performed dissection of the diverticulum and umbilical hernia repair for the incarcerated umbilical Littre's hernia under laparoscopy in a severely obese patient. The risk of mesh infection seems to be avoidable using a two-stage surgery, and the risk of recurrence can be reduced using the IPOM repair compared with simple suture closure.

Abstract
Background The European and American guidelines recommend that symptomatic umbilical hernias (UHs) are repaired using an open approach with a preperitoneal flat mesh. However, the standard treatment procedure for large UH in patients with extreme obesity is yet to be established. Here, we present the first case of a patient with morbid obesity undergoing laparoscopic UH repair using needlescopic instruments and an intraperitoneal onlay mesh plus repair (IPOM plus). Case presentation A 29-year-old man, who was classified as morbidly obese (body mass index, 36.7 kg/m2) noticed a reducible nontender mass in the umbilical region and was subsequently diagnosed with an UH, with a diameter of 4 cm. Laparoscopic IPOM plus repair was planned using a needlescopic method for a large UH in the patient with morbid obesity. A 3-mm rigid laparoscope was mainly used in the procedure. After a 12-mm trocar and two 3-mm trocars were inserted, fascial defect closure was performed using intracorporeal suturing with 0 monofilament polypropylene threads. Then, IPOM was performed laparoscopically using an 11.4-cm round mesh coated with collagen to prevent adhesions. The operative time and blood loss were 57 min and 1 g, respectively. The postoperative course was uneventful. Conclusions Reduced-port laparoscopic surgery using needlescopic instruments and an IPOM plus technique is a minimally invasive and convenient combination option for large UH in a patient with morbid obesity.

Abstract
PURPOSE Primary midline hernias arising in the linea alba are common. While mesh repair has been shown to reduce recurrence rates even in small hernias, many surgeons still use a suture repair for defects of less than 2 cm. The recent European and Americas Hernia Societies Guidelines recommended suture repair only for hernias smaller than 1 cm. A suture repair implies edge-to-edge or overlapping fascial margins, which necessarily involves tension on the repair. A darn is a tension-free repair where, in effect, a "mesh" is hand-woven across the defect in situ. METHODS The darn repair is a modification of the darn techniques for inguinal hernia repair. Eligible patients undergoing this repair at the Royal Infirmary of Edinburgh between 1 January 2008 and 31 December 2017 were identified from a prospective computer-based medical record system and their case notes reviewed. Inclusion criteria were adult patients with a primary midline abdominal wall defect smaller than 2 cm in the widest diameter of the hernia defect measured intra-operatively. Patients were followed up by telephone in 2019. Those who reported possible recurrence or other symptoms in the region of their hernia repair were reviewed in the outpatient clinic. RESULTS 47 suture-darn repairs were undertaken over the 10-year period. Fifteen of the darn repair operations (32%) were performed under local anaesthesia. Forty-one patients were followed up with a mean of 80 ± 35 and median of 87 months after surgery. Six patients (13%) were lost to follow-up. Recurrence was found in two cases (5%) and one patient has since been diagnosed with a new epigastric hernia some 5 cm cranial to the previous repair. CONCLUSIONS The darn repair for small primary midline hernias is quick and inexpensive with promising long-term results. It can be performed under local anaesthesia. It can serve as an alternative to mesh repair for defects less than 2 cm in maximum dimension.

Abstract
PURPOSE To examine hospital-level variation in the timing of asymptomatic umbilical hernia repair in children. METHODS Retrospective analysis of children undergoing umbilical hernia repair at 38 children's hospitals using the Pediatric Health Information System database (01/2013-12/2017). Early repair was defined as surgery performed at 3 years of age or younger. Repairs were categorized as emergent/urgent if associated with diagnostic or procedural codes indicating obstruction or strangulation, or if they occurred within 2 weeks of an emergency department encounter. Multivariable regression was used to calculate hospital-level observed-to-expected (O/E) ratios for early repair adjusting for emergent/urgent repair and patient characteristics. RESULTS 23,144 children were included, of which 30% underwent early repair (hospital range: 6.9%-54.3%, p ≪ 0.001). Overall, 3.8% of all repairs were emergent/urgent, and higher rates of early repair did not correlate with higher rates of emergent/urgent repair across hospitals (r = -0.10). Following adjustment, hospital-level O/E ratios for early repair varied 8.9-fold (0.19-1.70, p ≪ 0.001). CONCLUSION Timing of asymptomatic umbilical hernia repair varies widely across children's hospitals, and the magnitude of this variation cannot be explained by differences in patient characteristics or the acuity of repair. Many children may be undergoing repair of hernias that may spontaneously close with further observation. LEVEL OF EVIDENCE Level III (retrospective comparative study).

Abstract
PURPOSE The most common techniques used to repair umbilical hernias are open and laparoscopic. As the obesity epidemic in the United States is growing, it is essential to understand how this morbidity affects umbilical hernia repairs. This study compares laparoscopic versus open umbilical hernia repairs in obese patients. METHODS All patients with body mass index (BMI) ≥ 30 kg/m2 who underwent elective, open or laparoscopic repair of a primary umbilical hernia with mesh were identified from the Americas Hernia Society Quality Collaborative (AHSQC). A retrospective review of the prospectively collected data was conducted. Outcomes of interest included surgical site infections (SSI), surgical site occurrences requiring procedural intervention (SSOPI), hernia-related quality-of-life survey (HerQles), and long-term recurrence. A logistic regression model was used to generate propensity scores. RESULTS Of 1507 patients who met the inclusion criteria, 322 were laparoscopic, and 1185 were open cases. The laparoscopic group had higher mean BMI (37 ± 6 vs. 35 ± 5 kg/m2 , P < 0.001 ) and mean hernia width (3 cm ± 1 vs. 2 cm ± 2, P < 0.001). Using a propensity score model, we controlled for several clinically relevant covariates. Propensity score adjustment showed no differences in the 30-day HerQles score (OR 0.93, 95% CI 0.58-1.49), SSI (OR 1.57, 95% CI 0.52-4.77), SSOPI (OR 2.85, 95% CI 0.84-9.62) or hernia recurrence (hazard ratio 0.86, 95% CI 0.50-1.49). CONCLUSION In obese patients with primary umbilical hernias, there is likely no benefit to laparoscopy over open umbilical hernia repair with mesh with regard to wound morbidity. Although, the long-term recurrence also showed no difference between these two approaches, overall follow up was lacking.

Abstract
Robotic primary ventral hernia repair (PVHR) combines minimal access, closure of defect and pre-peritoneal mesh placement. The protocol designs a randomized single-blinded controlled trial comparing robotic PVHR to open PVHR. The primary outcome will be the incidence of wound-related complication within 1 month.
Background The objective of the present study is to compare the outcomes open PVHR and robotic PVHR. Methods/Design The present study will be a randomized single-blinded controlled trial with intention-to-treat analysis comparing robotic PVHR to open PVHR in adult patients undergoing elective PVHR with a defect ranging between 1–5 cm. Patient refusing to participate, not able to give informed consent, with history of intra-abdominal surgery contraindicating a robotic surgical approach will be excluded. The intervention will consist in laparoscopic robotically assisted trans-abdominal pre-peritoneal epigastric or umbilical PVHR with closure of fascial defect and non-adsorbable mesh reinforcement. The control will be open pre-peritoneal epigastric or umbilical hernia repair with closure of fascial defect and non-absorbable mesh reinforcement. The primary outcome will be the incidence of wound-related complication within 1 month. The secondary outcomes will be esthetic satisfaction, pain, pain-killers consumption, general complications, costs, operative time and early hernia recurrence. Discussion Open PVHR is potentially associated to more wound-related complications, but has the advantages of cost-effectiveness, short operative time and totally extra-peritoneal repair. Laparoscopic PVHR has lower wound-related complications but implies placing the mesh in intra-peritoneal position, requires advanced laparoscopic skills, usually does not allow the closure of the defect, and can lead to excessive pain and pain-killers consumption. Robotic PVHR uses the same laparoscopic access as laparoscopic PVHR, but thanks to the extended range of motion given by the robotic system, allows defect closure, pre-peritoneal placement of the mesh and requires less technical skills. In the present randomized controlled trial, we expect to show that robotic PVHR leads to better wound-related outcomes than open PVHR. Trial registration The present randomized controlled trial was registered into clinicaltrials.gov under registration number NCT04171921.

Abstract
Introduction: Umbilical hernia is a common pediatric disorder that pediatric surgeons are usually asked to manage. Most cases will be closed spontaneously during the first 4-5 years of life. Low number of studies regarding umbilical defects in children does not allow a definitive guideline to be drawn about their natural history, indications and optimal timing for repair. In this systematic review, we evaluated the existing literature where pediatric umbilical hernias are addressed in regards to watchful waiting versus recommendations on timing of operative repair and we compared our institutional results with current literature Aim: The aim of our study is to review and evaluate the current guidelines in management of umbilical hernias in children and to compare the results with our experience in management of umbilical hernia in our institution. Methods: Online literature search for studies that published about umbilical hernias in pediatric using literature’s search of ACP Journal Club, Clinical Evidence, Dynamed, Cochran Controlled Trial Register (1945-2015), UpToDate, and PubMed. We reviewed the recommendations of these studies regarding conservative treatment, rule and time of surgery, complications, and its natural history trend to close spontaneously. We compared the literature results and recommendations to our institutional results. We also conducted a retrospective medical charts review of 520 children aged between 1 month and 14 years presented to our institution for surgical consultation for asymptomatic umbilical hernia between 2007 and 2017. We only included children with umbilical hernia who are less than 14 years old and without other associated disorders. Results: A Total of 7 studies that met the inclusion criteria were reviewed. These studies examined the possibilities of spontaneous closure of hernia defect in pediatric, incidence of complications from watchful waiting and current recommendations for surgery timing. In general, spontaneous resolution were unlikely to be seen beyond the age of 5 years. Our institutional results found that of 442 cases treated conservatively between 2007 and 2017, 85% are closed spontaneously by 1-5 years of age. Conclusion: There is minimal top-notch clinical data guiding pediatric surgeons on management protocols in regards to umbilical hernias in children. Current published studies and our institutional retrospective study recommend that conservative management of asymptomatic, uncomplicated umbilical hernias until age 4-5 years is both safe and practical.
