RESUMO
Sublingual gland herniation into the submandibular space through a mylohyoid muscle defect is a common anatomical variation; however, salivary gland cancers that arise from a herniated sublingual gland have not been described yet. Here, we report three patients with salivary gland cancers originating from a herniated sublingual gland. All tumors were detected as palpable submandibular masses, located anterior to the submandibular gland, medial to the mandible, and lateral to the mylohyoid muscle, with contact with the sublingual gland through a mylohyoid muscle defect. Intraoperative findings confirmed that the masses were derived from herniated sublingual glands. Pathological examination showed one case of mucoepidermoid carcinoma and two cases of adenoid cystic carcinoma. Imaging findings of the tumor location, in addition to the continuity with the sublingual gland through the mylohyoid muscle defect, are crucial for accurately diagnosing the tumor origin, which is essential for determining the appropriate clinical management.

INTRODUCTION: Paraduodenal hernias (PDH) are rare congenital internal hernias with non- specific symptoms. Left-sided paraduodenal hernia is three times more common than right-sided paraduodenal hernia with similar clinical presentation but different embryological origins. MATERIALS AND METHODS: We report a series of eight cases of paraduodenal hernia who presented with varied clinical presentation ranging from vague abdominal pain to complete intestinal obstruction. Six cases had left-sided paraduodenal hernia, while two cases had right-sided paraduodenal hernia. RESULTS: Seven cases based on their presentation underwent surgery either electively or on emergent basis. Three cases underwent laparoscopic repair. One case had a recurrence and was re-operated four months later. There was no mortality among any of the cases. CONCLUSION: A pre-operative diagnosis of paraduodenal hernia is essential. Laparoscopic surgery is safe in select cases and is found to be beneficial.

A paraduodenal hernia is a rare type of hernia, however it is the most common type of internal hernias. It can develop after surgery, trauma, or be congenital. Paraduodenal hernias are rare in children. Clinical presentation is nonspecific. Patients range from being asymptomatic to presenting with clinical symptoms associated with small bowel obstructions. Diagnostic tools such as X-ray, plain abdominal radiography, and computed tomography may be used to diagnose paraduodenal hernias. Described is the case of a 5-year-old female who died suddenly of a bowel obstruction due to a paraduodenal hernia found at postmortem examination. In the hours prior to death, she reported stomach pain, vomiting, and later developed a fever. Postmortem CT study showed free fluid in the abdomen and bowel distention. Internal examination showed an obstructed bowel with ischemic sections extending from the distal portions of the small bowel up to the proximal portions of the transverse colon. The ischemic portions were entrapped within a clear membranous sac within the abdominal cavity. The sac was concluded to be a paraduodenal hernia. Paraduodenal hernias are rare and difficult to diagnose but they must be considered in the diagnostic process, as without surgical intervention the mortality rate can be high.

A 51 years old male had underwent aortic valve replacement (AVR) by minimally invasive cardiac surgery (MICS) for aortic regurgitation. About one year after the surgery, bulging of the wound and pain appeared. His chest computed tomography showed an image of the right upper lobe protruding from the thoracic cavity through the right second intercostal space, and the patient was diagnosed as having an intercostal lung hernia and the surgical treatment was performed using a unsintered hydroxyapatite and poly-L-lactide (u-HA/PLLA) mesh plate and monofilament polypropylene (PP) mesh. Postoperative course was uneventful without any evidence of recurrence.

BACKGROUND: Lung herniation is a rare condition, most often due to thoracic injury, but has also been described as a complication following cardiothoracic surgery. Here, we report two cases of post-surgical lung herniation following a neurosurgical mini-transthoracic (mini-TTA) for treatment of thoracic herniated discs. With this report we aim to make surgeons aware of this rare complication, review existing literature on surgical repairs and describe our novel correction technique using video assisted thoracic surgery (VATS) and a combination of mesh covering the muscle defect internally and nitinol rib plates for rib approximation on the outside of the thoracic cavity. CASE DESCRIPTION: Patient A was an 85-year-old man who presented with a subcutaneous swelling at the site of surgery following a left sided mini-TTA. Computed tomography (CT) revealed pulmonary tissue herniation. He underwent VATS guided reconstruction. Using two Ventralex meshes covering the defect on the inside and a NiTi-rib H-plate for rib approximation. Patient B was a 73-year-old woman who developed pulmonary complaints with a soft mass at the surgery site after a left sided mini-TTA. She also underwent VATS guided reconstruction. A large Sempramesh composite mesh and two NiTi-Rib H-plates were used. Recovery was uncomplicated and follow-up revealed no recurrence in both cases. CONCLUSION: These cases should make surgeons aware of the possibility of post-surgical development of lung herniation and describe successful correction using a combination of mesh material and NiTi-Rib H-plates through a VATS technique.

Intercostal pulmonary hernia is a rare condition that may present to the emergency department spontaneously, following blunt trauma or as a complication of thoracic surgery. With the evolution of minimally invasive thoracic surgery pulmonary hernia may become more common. In this case of postoperative chest pain, incisional swelling, and shortness of breath, we present the ultrasound characteristics of a postoperative intercostal pulmonary hernia and its resemblance to subcutaneous emphysema.

INTRODUCTION: Left paraduodenal hernia is an internal herniation that develops due to anomalous fetal development. If incarcerated, it becomes an unusual cause of acute abdomen. CASE REPORT: This case report presents an uncommon case of a 39-year-old man with acute abdominal pain with vomiting. The patients medical history included recurrent subileous events and Crohn´s disease in long-term remission. CT scan of abdominal cavity indicated a possible mechanical obstruction of small bowel loops in the upper left abdominal quadrant. Incarcerated left paraduodenal herniation was identified during surgery. Repositioned small bowel loops did not require resection and the entrance of Landzert´s fossa was sutured. CONCLUSION: Left paraduodenal hernia is the most common congenital internal herniation. Although rare, it should be considered in the differential diagnosis of acute abdomen.

Background: Herniation through foramen of Winslow is a relatively rare group of hernias characterized by protrusion of the abdominal contents into the lesser sac. To our knowledge, this is the youngest and the only reported case related to adolescents in the last five years. Case Presentation: A 15-year-old male patient presented to our emergency department after experiencing 4 hours of acute dull upper abdominal pain. We diagnosed the patient with herniation through foramen of Winslow by computed tomography (CT) and other complementary diagnostic methods. After a 3-trocar laparoscopic procedure, the hernia was successfully repositioned and no bowel resection was required. The patient was discharged on the fourth postoperative day without complications. He was no recurrence six months after operation. Conclusions: Through the review of the literature, it is clear that herniation through foramen of Winslow (HFW) is a more challenging condition to diagnose preoperatively, which can be achieved with the help of complementary diagnostics especially CT. As a category of diseases with a very low postoperative recurrence rate, clinical experience tells us that only three-trocar laparoscopic surgery can successfully return HFW.

Many eyes with macular pucker are characterized by a centripetal displacement of the inner foveal layers which may result in a disappearance of the foveal pit. In this retrospective case series of 90 eyes with macular pucker of 90 patients, we describe using spectral-domain optical coherence tomography different foveal configurations with ectopic inner foveal layers, document the relationship between posterior vitreous detachment (PVD) and idiopathic epiretinal membrane (ERM) formation and spontaneous and postoperative morphological alterations of the fovea, and propose an active role of Müller cells in the development of foveal herniation. We found that ERM were formed during or after partial perifoveal PVD, or after foveal deformations caused by tissue edema. The ERM-mediated centripetal displacement of the inner foveal layers and in various eyes anterior hyaloidal traction caused a disappearance of the foveal pit and an anterior stretching of the foveola with a thickening of the central outer nuclear layer (ONL). After the edges of the thickened inner layers of the foveal walls moved together, continuous centripetal displacement of the inner foveal layers generated a bulge of the fovea towards the vitreous (foveal herniation). Macular pseudoholes with a herniation of the inner foveal layers show that the outer layer of the protruding foveal walls is the outer plexiform layer (OPL). If the ERM covered the foveal walls and parafova, but not the foveola, the inner layers of the foveal walls were not fully centripetally displaced and the foveal pit was present. The visual acuity of eyes with ectopic inner foveal layers was inversely correlated with the thickness of the foveal center. Spontaneous morphological alterations after disappearance of the foveal pit may include the development of cystoid macular edema or additional thickening of the foveal tissue and foveal herniation. The foveal configuration with ectopic inner layers of the foveal walls and a thick central ONL persisted over longer postoperative time periods. The data show that the centripetal displacement of the inner foveal layers in eyes with macular pucker, which results in a disappearance of the foveal pit, may also generate foveal herniation which is suggested to be caused by contraction of Müller cell processes in the OPL. The centripetal displacement of the inner foveal layers and the formation of foveal herniation are suggested to reverse the foveal pit formation during development.

BACKGROUND: Precise visualization of meshes and their position would greatly aid in mesh shrinkage evaluation, hernia recurrence risk assessment, and the preoperative planning of salvage repair. Lightweight (LW) meshes are able to preserve abdominal wall compliance by generating less post-implantation fibrosis and rigidity. However, conventional 3D imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) cannot visualize the LW meshes. Patients sometimes have to undergo a second-look operation for visualizing the mesh implants. The goal of this work is to investigate the potential advantages of Automated 3D breast ultrasound (ABUS) pore texture analysis for implanted LW hernia mesh identification. METHODS: In vitro, the appearances of four different flat meshes in both ABUS and 2D hand-held ultrasound (HHUS) images were evaluated and compared. In vivo, pore texture patterns of 87 hernia regions were analyzed both in ABUS images and their corresponding HHUS images. RESULTS: In vitro studies, the imaging results of ABUS for implanted LW meshes are much more visualized and effective in comparison to HHUS. In vivo, the inter-class distance of 40 texture features was calculated. The texture features of 2D sectional plans (axial and sagittal plane) have no significant contribution to implanted LW mesh identification. Significant contribution was observed in coronal plane. However, since the mesh may have spatial variation such as shrinkage after implantation surgery, the inter-class distance of 3D coronal plane pore texture features are bigger than 2D coronal plane, so the contribution of 3D coronal plane pore texture features are more valuable than 2D coronal plane for implanted LW mesh identification. The use of 3D pore texture features significantly improved the robustness of the identification method in distinguishing between LW mesh and fascia. CONCLUSIONS: An innovative new ABUS provides additional pore texture visualization, by separating the LW mesh from the fascia tissues. Therefore, ABUS has the potential to provides more accurate features to characterize pore texture patterns, and ultimately provide more accurate measures for implanted LW mesh identification.

Spinal cord herniation (SCH) is a rare condition associated with tethering of the spinal cord at the ventral dural defect. Idiopathic dorsal spinal cord herniation (IDSCH) is an extremely rare clinical entity. Here, we report the first case of IDSCH perforating the lamina in a patient with a history of ossification of the ligamentum flavum and diffuse idiopathic skeletal hyperostosis. Untethering of the spinal cord was performed by removing the surrounded ossified dura. Although urological symptoms and impaired proprioception remained, progressive neurological deterioration was prevented. Because this disease condition is extremely rare, it should be differentiated from ventral SCH.

Enteroceles and rectoceles are often identified as the cause of a vaginal mass and pelvic discomfort. The combination of a rectocele and an enterocele as pelvic organ prolapses is not infrequent; however, there are few reports on possible simultaneous treatments of these two conditions. We report a new and simple procedure for repairing an enterocele during a transvaginal anterior levatorplasty with posterior colporrhaphy for a rectocele repair. This technique involves making an excision in the peritoneal sac, with high ligation, and attaching the uterine cervix and/or cardinal ligament to the upper most part of the approximation of the levator muscles, to reinforce and lift the deep peritoneal sac. This procedure allows for transvaginal repair of both an enterocele and a rectocele. The enterocele is visualized by applying barium to the posterior vaginal wall during defecography.

OBJECTIVE: Decompressive craniectomy (DC) improves functional outcomes in selected patients with malignant hemispheric infarction (MHI), but variability in the surgical technique and occasional complications may be limiting the effectiveness of this procedure. Our aim was to evaluate predefined perioperative CT measurements for association with post-DC midline brain shift in patients with MHI. METHODS: At two medical centers we identified 87 consecutive patients with MHI and DC between January 2007 and December 2019. We used our previously tested methods to measure the craniectomy surface area, extent of transcalvarial brain herniation, thickness of tissues overlying the craniectomy, diameter of the cerebral ventricle atrium contralateral to the stroke, extension of infarction beyond the craniectomy edges, and the pre and post-DC midline brain shifts. To avoid potential confounding from medical treatments and additional surgical procedures, we excluded patients with the first CT delayed >30 hours post-DC, resection of infarcted brain, or insertion of an external ventricular drain during DC. The primary outcome in multiple linear regression analysis was the postoperative midline brain shift. RESULTS: We analyzed 72 qualified patients. The average midline brain shift decreased from 8.7 mm pre-DC to 5.4 post-DC. The only factors significantly associated with post-DC midline brain shift at the p<0.01 level were preoperative midline shift (coefficient 0.32, standard error 0.10, p=0.002) and extent of transcalvarial brain herniation (coefficient -0.20, standard error 0.05, p <0.001). CONCLUSIONS: In patients with MHI and DC, smaller post-DC midline shift is associated with smaller pre-DC midline brain shift and greater transcalvarial brain herniation. This knowledge may prove helpful in assessing DC candidacy and surgical success. Additional studies to enhance the surgical success of DC are warranted.

The patient was a 69-year-old man with localized cT1cN0M0 prostate cancer, who underwent robotassisted laparoscopic prostatectomy (RALP). The operation time was 188 minutes, blood loss was 300 ml, including urine, and no intraoperative complications were noted. The fourth day after RALP, he suddenly complained of nausea and vomiting, and there was right lateral abdominal tenderness. Emergency abdominal computed tomographic scan revealed small intestinal hernia in the right lower abdomen, and we performed emergency laparoscopic surjery. At re-operation, we found lacerations of the peritoneum and transversus abdominis fascia at the insertion site of the 12 mm assistant port, and prolapse of the small intestine. Our diagnosis was lateral port site hernia following RALP. There was no necrosis in the small intestine. The transversus abdominis fascia was Z-sutured through the abdominal cavity with an absorbable thread, and the oblique abdominis muscle was Z-sutured extracorporeally to complete the operation. The patient was discharged on the eleventh day with good progress after re-operation. The possibility of lateral port-site hernia after RALP should be kept in mind, and more reliable port-site closure should be considered.

INTRODUCTION: Pulmonary hernias are rare conditions, most are the results of an injury or previous thoracic surgery. CASE REPORT: We present a case of a 48-year-old woman injured in a car accident. The examination in the trauma centre revealed a chest injury with herniation of the lung parenchyma into the chest wall and fractures of long bones of lower limbs. Initially, an osteosynthesis of the left femur and the right tibia fracture were performed. The patient underwent a subsequent surgery to repair the pulmonary hernia. CONCLUSION: A pulmonary hernia is diagnosed either directly during a clinical examination or by imaging. A sovereign diagnostic method is a computed tomography. The method of treatment is a surgical repair with primary suture of the chest wall defect or implantation of a mesh to repair the pulmonary hernia.

OBJECTIVES: To confirm that structured reporting of CT scans using ten signs in clinical practice leads to a better accuracy in diagnosing internal herniation (IH) after gastric bypass surgery, compared with free-text reporting. METHODS: In this prospective study, CT scans between June 1, 2017, and December 1, 2018, were included from a cohort of 2606 patients who had undergone laparoscopic gastric bypass surgery between January 1, 2011, and January 1, 2018. The CT scans were made for a suspicion of IH and structured reports were made using a standardised template with ten signs: (1) swirl sign, (2) small-bowel obstruction, (3) clustered loops, (4) mushroom sign, (5) hurricane eye sign, (6) small bowel behind the superior mesenteric artery, (7) right-sided anastomosis, (8) enlarged nodes, (9) venous congestion, and (10) mesenteric oedema. Furthermore, an overall impression of IH likelihood was given using a 5-point Likert scale. CT scans performed in 2011 until 2017, without structured reporting, were included for comparison. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated using two-way contingency tables; the chi-square test was used for calculating p value. Reoperation and 3-month follow-up were used as reference. RESULTS: A total of 174 CT scans with structured reporting and 289 CT scans without structured reporting were included. Sensitivity was 81.3% (95% CI, 67.7-94.8%) and 79.5% (95% CI, 67.6-91.5%), respectively (p = 0.854); specificity was 95.8% (95% CI, 92.5-99.1%) and 88.6% (95% CI, 84.6-92.6%), respectively (p = 0.016); PPV was 81.3% (95% CI, 67.7-94.8%) and 55.6% (95% CI, 43.3-67.8%), respectively (p = 0.014); NPV was 95.8% (95% CI, 92.5-99.1%) and 96.0% (95% CI, 93.5-98.6%), respectively (p = 0.909); and accuracy was 93.1% (95% CI, 88.0-96.2%) and 87.2% (95% CI, 82.7-90.7%), respectively (p = 0.045). CONCLUSION: Structured reporting for the diagnosis of internal herniation after gastric bypass surgery improves accuracy and can be implemented in clinical practice with good results. KEY POINTS: ⢠Ten signs are used to aid CT diagnosis of internal herniation after gastric bypass surgery. ⢠Structured reporting increases specificity and positive predictive value and thereby prevents unnecessary reoperations in patients without internal herniation. ⢠Structured reporting by means of a standardised template can help less experienced readers.

AIM: Data on the pathogenesis and symptoms of enterocele are limited. The objectives of this study were to determine the clinical phenotype of patients with enterocele, to highlight the main functional and/or anatomical associations and to improve the accuracy of the preoperative assessment of pelvic floor disorders. METHOD: A total of 588 patients who were referred to a tertiary unit for an anorectal complaint completed a self-administered questionnaire and underwent physical examination, anorectal manometry and defaecography. Using defaecography, enterocele was defined as a radiological hernia of the small bowel into an enlarged rectovaginal space. One hundred and thirty-five patients with enterocele were age- and gender-matched with 270 patients without enterocele. Factors associated with enterocele were assessed using univariate and multivariate analysis models. RESULTS: Patients with enterocele were less frequently obese than patients without enterocele (8/135 vs 36/270; P = 0.02) and more frequently had a past history of pelvic surgery (51/135 vs 75/270; P = 0.04). They complained more frequently of pelvic pain on bearing down (29/135 vs 24/270; P = 0.003), anal procidentia (37/135 vs 46/270; P = 0.01) and more frequently had irritable bowel syndrome (83/135 vs 131/270; P = 0.01) and severe constipation according to the Kess score (104/135 vs 182/270; P = 0.04). Anorectal function was comparable between the two groups. Patients with enterocele had more frequent rectoceles and overt rectal prolapses than patients without enterocele. CONCLUSIONS: Enterocele should be investigated in patients with chronic pelvic pain, overt rectal prolapse and/or a past history of pelvic surgery.

INTRODUCTION: BMI and hernia defect size are strongly associated with outcomes after open ventral hernia repair (OVHR). The impact of abdominal subcutaneous fat (SQV), intra-abdominal volume (IAV), hernia volume (HV), and ratio of HV to intra-abdominal volume (HV:IAV, representing visceral eventration) is less clearly elucidated. This study examines the interaction of multiple markers of adiposity and hernia size in OVHR. METHODS: OVHR with preoperative CT scans were identified. 3D volumetric software measured HV, SQV, IAV, and HV:IAV was calculated. A principal component analysis was performed to create new component variables for collinear variables. Hernia PC was composed primarily of hernia dimensions, EAV (extra-abdominal volume PC) included SQV and BMI, and IAV PC included IAV. RESULTS: A total of 1178 OVHR patients had a preoperative CT scan. Their demographics included a mean age of 58.5 ± 12.4 years, BMI of 34.2 ± 7.7 kg/m2, and 57.8% were female. The mean defect area was 150.8 ± 136.7 cm2, and 66.0% were recurrent, Patients had mean SQV of 6719.4 ± 3563.9 cm3, HV of 966.9 ± 1303.5 cm3, IAV of 4250.2 ± 2118.1 cm3, and a HV:IAV of 0.29 ± 0.46. In multivariate analysis, Hernia PC was associated with panniculectomy (OR 1.52, CI 1.37-1.69) and component separation (OR 1.34, CI 1.21-1.49) and was negatively associated with fascial closure (OR 0.78, CI 0.69-0.88). Hernia PC was also associated with reoperation, readmission, and development of wound complications (OR 1.18, CI 1.08-1.30; OR 1.15, CI 1.04-1.27; OR 1.28, CI 1.16-1.41, respectively). EAV PC was associated with performance of a panniculectomy (OR 1.33, CI 1.20-1.48), readmission (OR 1.18, CI 1.06-1.32), and wound complications (OR 1.41, CI 1.27-1.57). IAV PC was not associated with adverse outcomes. CONCLUSION: Values of hernia area, volume, IAV, HV:IAV, BMI, and SQV are collinear markers of patient obesity and hernia proportions. They are distinct enough to be represented by three principal component variables, indicating more nuanced discrete influences on variability of surgical outcomes other than BMI.
