Falciform Ligament Torsion Caused by Omental Hernia Through the Foramen of Morgagni.

INTRODUCTION: Torsion of the falciform ligament, one of the rarest causes of acute abdominal pain, often presents with pain in the right upper quadrant and epigastrium. CASE PRESENTATION: In this case, we present the Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) findings of torsion of the falciform ligament that occurred in the presence of omental fat herniation through the foramen of Morgagni in an 88-year-old female patient who presented to the emergency department with acute epigastric pain. CONCLUSION: Torsion of the falciform ligament may develop secondary to omental hernia in the setting of Morgagni hernia and should be taken into consideration as one of the rarest causes of acute abdominal pain, even in elderly patients.

Multilayer fibroin/chitosan oligosaccharide lactate and pullulan immunomodulatory patch for treatment of hernia and prevention of intraperitoneal adhesion.

This study aims to develop a novel intraperitoneal two- or three-layered patch with immunomodulatory property for treatment of hernia, regeneration of abdominal wall and prevention of intraperitoneal adhesions. Polypropylene (PP) mesh, middle layer, was intended to provide mechanical support whereas pullulan (PUL) hydrogel coating layer was designed to prevent intraperitoneal adhesions. Fibroin/chitosan oligosaccharide lactate (F/COS) layer electrospun on one side of pullulan was chosen for immunomodulation and abdominal wall regeneration. Physical and mechanical properties and regenerative capacity of intraperitoneal patches were determined. Immunomodulatory property of electrospun layer and whole patch was studied by determining nitric oxide amount produced by RAW 264.7 macrophages. 25 % (w/v) PUL hydrogel and F/COS with 90:10 (w/w) ratio yielded optimal results. Here, we report that fabricated intraperitoneal patches successfully prevented cell adhesion on one side and increased cell viability and proliferation on other side, along with immunomodulation, in vitro.

Engineering multifunctional bactericidal nanofibers for abdominal hernia repair.

The engineering of multifunctional surgical bactericidal nanofibers with inherent suitable mechanical and biological properties, through facile and cheap fabrication technology, is a great challenge. Moreover, hernia, which is when organ is pushed through an opening in the muscle or adjacent tissue due to damage of tissue structure or function, is a dire clinical challenge that currently needs surgery for recovery. Nevertheless, post-surgical hernia complications, like infection, fibrosis, tissue adhesions, scaffold rejection, inflammation, and recurrence still remain important clinical problems. Herein, through an integrated electrospinning, plasma treatment and direct surface modification strategy, multifunctional bactericidal nanofibers were engineered showing optimal properties for hernia repair. The nanofibers displayed good bactericidal activity, low inflammatory response, good biodegradation, as well as optimal collagen-, stress fiber- and blood vessel formation and associated tissue ingrowth in vivo. The disclosed engineering strategy serves as a prominent platform for the design of other multifunctional materials for various biomedical challenges.

Investigation of a connection between abdominal wall defects and severity of the herniation in fetuses with gastroschisis and omphalocele.

Analyze the biometric parameters and the size (area) of abdominal wall defect (AWD) in fetuses with gastroschisis and omphaloceles and correlate them with the herniated internal organs. We studied 22 fetuses (11 with AWDs and 11 without anomalies). In all fetuses we evaluated the xiphopubic distance (XPD) and iliac crest distance (ICD). In fetuses with AWDs we dissected the abdominal wall and measured the width and length of the defect for calculating its area and studying the correlation between the size of the defect with the organs that were herniated. For statistical analysis, the Anova and Tukey post-test were used (p < 0.05). The XPD in the control group had mean of 4.2 mm (2.3-5.9; SD ± 1.11), while in the AWDs it was 4.2 mm (2.9-5.5; SD ± 0.98) (p = 0.4366). The ICD had mean values of 2.5 mm (1.6-3.4; SD ± 0.58) in the control group, and 2.3 mm (1.2-3.0; SD ± 0.56) in AWDs fetuses (p = 0.6963). The number of herniate organs do not have significant correlation with the area of the defect (r2 = 0.2504, p = 0.5068). There is no correlation between the size (area) of abdominal wall defects and the number of the internal organs that herniated. Therefore, the hole size is not a predictor of the severity of the gastroschisis or omphalocele.

Systemic biomarkers currently implicated in the formation of abdominal wall hernia: A systematic review of the literature.

BACKGROUND: Surgery to the abdominal wall is ubiquitous worldwide and hernia treatment is challenging and expensive, posing a critical need to tailor treatment to individual patient risk-factors. In this systematic review, we consider specific systemic factors with potential as biomarkers of hernia formation. METHODS: A healthcare database-assisted search, following PRISMA guidelines, identified journal articles for inclusion and analysis. RESULTS: 14 biomarker studies were selected, comparing hernia patients and hernia-free controls, focusing on markers of extracellular matrix (ECM) remodelling and collagen turnover. Matrix metalloproteinase-2 was increased in patients with inguinal hernia. Markers of type IV collagen synthesis were increased in patients with abdominal wall hernia; while markers of fibrillar collagen synthesis were reduced. Additional other ECM signalling proteins differ significantly within published studies. CONCLUSION: We identify a lack of high-quality evidence of systemic biomarkers in tailoring treatment strategies relative to patient-specific risks, but recognise the potential held within biomarker-based diagnostic studies to improve management of hernia pathogeneses.

Is Histopathological Evaluation of Hernia Sacs Necessary?

BACKGROUND: Our aim was to investigate the pathologies in the hernia sac in adults, and the frequency of malignancy as well as to confirm the necessity of maintaining the current applications in histological examination of the hernia sac. METHODS: Patients who were operated for hernia in our clinic from 2013 to 2019 were included in the study. Patient data were evaluated retrospectively. We divided the patients into four groups, according to the type of hernia. We evaluated the demographic characteristics of the patients, the pathologies within the hernia sac, histopathological examination outcomes of the hernia sac and clinical features of malignancy in patients with malignancy. RESULTS: A total number of 556 adult patients underwent inguinal, femoral, umbilical or incisional hernia repair in our hospital. Nine patients (0.61%) had malignancy in the hernia sac. Three out of nine patients (33%) had no preoperative diagnosis of malignancy. Six patients (67%) had a known history of malignancy. Two tumors were located in the inguinal (22.0%), six tumors in the incisional (67%), and one in the umbilical (11%) hernia sacs. Among these, 56% were of gastrointestinal, 22% of gynecological, 11% of breast and 11% of epididymis origin. Most of the other pathologies found in the hernia sac were herniated bowel segments, lipomas and omentum. CONCLUSION: Since the hernia sac might be the first clue for an underlying cancer, if abnormal pathological findings are detected during surgery, histopathological examination should be performed to exclude malignancy. The purpose of histological examination is to detect a hidden malignancy.

Laparoscopic preperitoneal repair for primary falciform ligament herniation.

Epigastric hernia involving the falciform ligament is exceptionally rare. Most reported cases are incisional hernia secondary to prior abdominal surgery. We report a case of primary falciform ligament herniation into the epigastric region repaired by the laparoscopic preperitoneal approach. In this case, an accompanying vessel along the herniated falciform ligament was identified. This finding provides a basis for the hypothesis of a perforating vessel piercing the linea alba and thereby creating a weak point for hernia protrusion (Moschowitz theory). The patient had an uneventful recovery and was discharged home on the postoperative day two. A laparoscopic preperitoneal approach is feasible for the repair of primary falciform ligament herniation. The magnified endoscopic view enables surgeons to achieve definite repair without missing occult defects.

An internal hernia caused by Meckel's diverticulum: a case report.

BACKGROUND: Meckel's diverticulum is a remnant of the omphalomesenteric duct. It can lead to intestinal perforation, obstruction and gastrointestinal bleeding. While the internal hernia caused by Meckel's diverticulum is rarely reported. CASE PRESENTATION: We report a case of a 45-year old female patient who presented with intestinal obstruction and on laparotomy was found to have Meckel's diverticulum with internal hernia causing intestinal gangrene. Segmental bowel resection was performed and the patient had uneventful recovery. CONCLUSIONS: In patients with acute intestinal obstruction without previous abdominal surgery, Meckel's diverticulum and its complications should be suspected.

Failure of abdominal wall closure after intestinal transplantation: Identifying high-risk recipients.

Open abdomen and fascial dehiscence after intestinal transplantation increase morbidity. This study aims to identify recipient and donor factors associated with failure to achieve sustained primary closure (failed-SPC) of the abdomen after intestinal transplant. We conducted a single-center retrospective study of 96 intestinal transplants between 2013 and 2018. Thirty-eight (40%) were adult patients, and 58 were pediatric patients. Median age at transplantation was 36.0 and 5.8 years, respectively. Failed-SPC occurred in 31 (32%) patients. Identified risk factors of failed-SPC included preexisting enterocutaneous fistula (OR: 6.8, CI: 2.4-19.6, P = .0003), isolated intestinal graft (OR: 3.4, CI: 1.24-9.47, P = .02), male sex in adults (OR: 3.93, CI: 1.43-10.8, P = .009), and age over four years (OR: 6.22, CI: 1.7-22.7, P = .004). There was no association with primary diagnosis and prior transplant with failed-SPC. Donor-to-recipient size ratios did not predict failed-SPC. There was an association between failed-SPC and extended median hospital stay (100 vs 57 days, P = .007) and increased time to enteral autonomy in pediatric patients. There is a relationship between failed-SPC and a higher rate of laparotomy (OR: 21.4, CI: 2.78-178.2, P = .0003) and fistula formation posttransplant (OR: 11.4, CI: 2.83-45.84, P = .0005) in pediatric patients. Given inferior outcomes with failed-SPC, high-risk recipients require careful evaluation.

Multifunctional prosthetic polyester-based hybrid mesh for repairing of abdominal wall hernias and defects.

This study involves the design, development and evaluation of a new multifunctional prosthetic mesh for treatment of abdominal wall defects without complications. The developed prosthetic mesh is a hybrid platform of both synthetic and natural materials with its backbone consisting of a synthetic commercial polyester fabric (CPF) to provide the required mechanical integrity. The CPF mesh was coated by a natural biodegradable, biocompatible and antimicrobial layer of chitosan (CS) incorporating phenytoin (PH)-loaded pluronic nanomicelles for healing promotion, and ciprofloxacin (CPX)-alginate polyelectrolyte complex-based microparticles as antibacterial agent. The prosthetic mesh was optimized and evaluated in-vitro and in-vivo. The optimum PH-loaded micelles had particle size of 95.42 nm, polydispersity index of 0.41, zeta potential of -18 and entrapment efficiency of 89.4%, while the optimum CPX microcomplexes had particle size of 1292.0 nm, polydispersity index of 0.8, zeta potential of -20.1, complexation efficiency of 81.1%, and minimum inhibitory concentration of 0.25 µg/ml and 0.125 µg/ml against Staphylococcus aureus and Pseudomonas aeruginosa, respectively. In-vivo study on abdominal wall defect dog model was conducted, followed by implantation of the proposed prosthetic meshes. The developed mesh depicted an efficient healing with excellent biocompatibility, and could be an ideal and feasible alternative prosthesis with many advantages such as low cost, inertness, mechanical stability, pliability, low infection rate, limited modification by body tissues, sterilizability, non-carcinogenicity, limited inflammatory reaction, hypoallergenic as well as minimal complications.

Herniation of the hepatic flexure through the foramen of Winslow, and a review of literature describing the minimally invasive technique.

Foramen of Winslow hernias is a rare and challenging diagnosis as signs and symptoms are usually non-specific. CT imaging has become the method of choice in diagnosing such conditions preoperatively. Traditionally managed via laparotomy, there has been an increase in the use of the minimally invasive technique in recent times, though experience remains sparse. This is a case of a 73-year-old woman with hepatic flexure herniation through the foramen of Winslow who was managed by the traditional laparotomy approach. A review of the literature was performed to learn key techniques in the use of laparoscopy to manage future cases.

Transjejunal Laparoscopic-Assisted ERCP: a Technique to Deal with Choledocholithiasis After Roux-En-Y Reconstruction.

INTRODUCTION: In Roux-en-Y reconstructions, choledocholithiasis could represent a really challenging condition to treat which can be treated by a surgical-assisted ERCP. Only six cases of transjejunal laparoscopic-assisted ERCP (LAERCP) can be found in literature to date and no large series are present. METHODS: A young woman who had undergone a laparoscopic Roux-en-Y gastric bypass 2 years earlier came complaining recurrent abdominal pain. Radiologic exams found stones in the common bile duct and no signs of internal hernia. We therefore decided to perform a transjejunal LAERCP finding a concomitant internal hernia in the Petersen's space which was repaired at the same time. RESULTS: The post-operative course was uneventful. CONCLUSION: Transjejunal LAERCP is a feasible technique to deal with choledocholithiasis, and it allows at the same time to identify and treat concomitant conditions like internal hernias.

An infant autopsy case of bowel obstruction due to internal abdominal hernia.

Internal abdominal hernia, defined as protrusion of viscera through a defect of the mesentery, has been considered a rare clinical entity. Recent clinical reviews reported a wide range of onset age (from newborns to the elderly) and symptoms (from minimal abdominal symptoms to severe acute abdomen). Sudden and unexpected death due to internal abdominal hernia is rare in infants or toddlers, and only 4 autopsy cases had been reported previously. We report the case of a 3-month-old Japanese boy who unexpectedly died 4 h after first vomiting. Autopsy showed a wide bowel obstruction with necrosis through a congenital mesenteric defect. The larynx was filled with gastric content (milky white viscous muddy material). In the cross section of both lungs, the same material was found to be expressed from the bronchioles. We diagnosed the cause of death as asphyxiation by viscous milk/vomitus aspiration caused by bowel obstruction due to an internal abdominal hernia. In case of sudden and unexpected death of an infant, autopsy is crucial to determine the cause of death. During autopsy, it is helpful to determine the character and distribution of gastric and airway contents to confirm milk or vomitus aspiration.
