Incarceration of a part of the gastric wall into the abdominal cavity in a patient with hiatal hernia and complete dislocation of the stomach (upside-down stomach).

An upside-down stomach is a rare type of hiatal hernia. An 83-year-old woman presented to the emergency room with abdominal pain and vomiting. Computed tomography revealed an upside-down stomach and the incarceration of a part of the gastric body into the abdominal cavity. Upper gastrointestinal endoscopy revealed a circular ulcer caused by gastric ischemia. Although she was discharged after 1 week of conservative therapy, she was readmitted to the hospital 1 day after discharge because of a recurrence of hiatal hernia incarceration. She underwent laparoscopic surgery 4 days after readmission and recovered successfully.

Incidence and risk factors for perineal hernia after robotic abdominoperineal resection: a single-center, retrospective cohort study.

BACKGROUND: Perineal hernia (PH) is a late complication of abdominoperineal resection (APR) that may compromise a patient's quality of life. The frequency and risk factors for PH after robotic APR adopting recent rectal cancer treatment strategies remain unclear. METHODS: Patients who underwent robotic APR for rectal cancer between December 2011 and June 2022 were retrospectively examined. From July 2020, pelvic reinforcement procedures, such as robotic closure of the pelvic peritoneum and levator ani muscles, were performed as prophylactic procedures for PH whenever feasible. PH was diagnosed in patients with or without symptoms using computed tomography 1 year after surgery. We examined the frequency of PH, compared characteristics between patients with PH (PH+) and without PH (PH-), and identified risk factors for PH. RESULTS: We evaluated 142 patients, including 53 PH+ (37.3%) and 89 PH- (62.6%). PH+ had a significantly higher rate of preoperative chemoradiotherapy (26.4% versus 10.1%, p = 0.017) and a significantly lower rate of undergoing pelvic reinforcement procedures (1.9% versus 14.0%, p = 0.017). PH+ had a lower rate of lateral lymph node dissection (47.2% versus 61.8%, p = 0.115) and a shorter operative time (340 min versus 394 min, p = 0.110). According to multivariate analysis, the independent risk factors for PH were preoperative chemoradiotherapy, not undergoing lateral lymph node dissection, and not undergoing a pelvic reinforcement procedure. CONCLUSIONS: PH after robotic APR for rectal cancer is not a rare complication under the recent treatment strategies for rectal cancer, and performing prophylactic procedures for PH should be considered.

A novel technique for the single-port laparoscopic percutaneous extraperitoneal closure (SLPEC) of paediatric isolated giant inguinal hernias using double-modified hernia needles.

The objective was to explore the efficacy of single-port laparoscopic percutaneous extraperitoneal closure using double-modified hernia needles with hydrodissection (SLPEC group) and two-port laparoscopic percutaneous extraperitoneal closure (TLPEC group) for the treatment of giant indirect inguinal hernias in children. We performed a retrospective review of all children with giant indirect inguinal hernias (inner ring orifice diameter ≥ 1.5 cm) who underwent laparoscopic high ligation of the hernia sac at FuJian Children's Hospital from January 2019 to December 2021. We collected data from the medical records of all the children and analysed their clinical characteristics and operation-related and follow-up information. Overall, this study included a cohort of 219 patients with isolated giant inguinal hernias who had complete clinical data and who had undergone laparoscopic high ligation of the hernia sac at our centre. All procedures were successfully performed for the 106 patients who underwent SLPEC and for the 113 patients who underwent TLPEC at our centre. There were no statistically significant differences in patient age, sex, body weight, follow-up time or the side of inguinal hernia between the SLPEC group and the TLPEC group (P = 0.123, 0.613, 0.121, 0.076 and 0.081, respectively). However, there were significant differences in the bleeding volume, visual analogue scale (VAS) score, and postoperative activity time between the two groups (P ≤ 0.001). The operation times in the TLPEC group were significantly longer than those in the SLPEC group (P = 0.048), but there were no significant differences in hospital length of stay or hospitalization costs between the two groups (P = 0.244 and 0.073, respectively). Incision scars were found in 2 patients in the SLPEC group and 9 patients in the TLPEC group, and there was a significant difference between the two groups (P = 0.04). However, the incidence of ipsilateral hernia recurrence, surgical site infection, suture-knot reactions and chronic inguinodynia did not significantly differ between the two groups (P = 0.332, 0.301, 0.332 and 0.599, respectively). Postoperative hydrocele occurred in only 1 male child in the SLPEC group and in no male children in the TLPEC group, and there was no difference between the two groups (P = 0.310). In this study, there were no cases of testicular atrophy or iatrogenic ascent of the testis. Compared with the TLPEC group, the SLPEC group had the advantages of a concealed incision, light scarring, minimal invasiveness, a reduced operation time, minimal bleeding, mild pain and rapid recovery. In conclusion, SLPEC using double-modified hernia needles with hydrodissection and high ligation of the hernia sac is a safe, effective and minimally invasive surgery. The cosmetic results are impressive, and the follow-up results are promising.

Amniotic fluid-derived small extracellular vesicles for predicting postnatal severe outcome of congenital diaphragmatic hernia.

Congenital diaphragmatic hernia (CDH) is a life-threatening condition with high morbidity and mortality rates. The survival rate of neonates with severe CDH is reportedly only 10%-15%. However, prenatal prediction of severe cases is difficult, and the discovery of new predictive markers is an urgent issue. In this study, we focused on microRNAs (miRNAs) in amniotic fluid-derived small EVs (AF-sEVs). We identified four miRNAs (hsa-miR-127-3p, hsa-miR-363-3p, hsa-miR-493-5p, and hsa-miR-615-3p) with AUC > 0.8 to classify good prognosis group and poor prognosis group in human study. The AUC for hsa-miR-127-3p and hsa-miR-615-3p, for predicting the poor prognosis, were 0.93 and 0.91, respectively. In addition, in the in vivo study, the miRNA profiles of the lung tissues of CDH rats were different from those of control rats. Additionally, two elevated miRNAs (rno-miR-215-5p and rno-miR-148a-3p) in the lung tissues of CDH rats were increased in the AF-sEVs of CDH rats. Our results suggest that severe CDH neonates can be predicted prenatally with high accuracy using miRNAs contained in AF-sEVs. Furthermore, miRNA profile changes in AF-sEVs reflected the lung status in CDH. Our findings may contribute to the development of advanced perinatal care for patients with CDH.

Incarcerated Bochdalek Hernia in Adults.

In this case report, the diagnostic challenge and emergency management of a Bochdalek hernia in adults in Mexico are outlined. This case report can help the medical community to consider the clinical presentation in adults and the importance of early diagnosis and management. We present a 57-year-old female patient with a history of arterial hypertension who, following a bout of abdominal pain, was diagnosed with a Bochdalek hernia. Following emergency surgery, there was an increase in intra-abdominal pressure, which was continuously monitored due to the possibility of compartment syndrome, potentially necessitating a second emergency surgery.

Amyand's Hernia: An Uncommon Encounter of an Appendiceal Presence in an Inguinal Hernia.

Amyand's hernia is a rare variant of inguinal hernia characterized by the presence of the vermiform appendix within the hernia sac. It represents a unique diagnostic and management challenge for surgeons due to its low incidence and varied clinical presentations. Here, we present a case of a 45-year-old man with a one-year history of right inguinoscrotal swelling, diagnosed as a right indirect inguinal hernia. Preoperative imaging revealed the presence of omentum within the hernia sac. Intraoperatively, both the omentum and the vermiform appendix were found within the sac without evidence of inflammation. The patient underwent successful Lichtenstein meshplasty without appendicectomy. This case highlights the importance of considering Amyand's hernia in the differential diagnosis of inguinal hernias and the significance of intraoperative findings in guiding surgical management. Further studies and case reports are needed to enhance our understanding of this rare clinical entity and optimize patient outcomes.

Major Complication Caused by Inguinal Hernia Recurrence After Percutaneous Internal Ring Suturing Procedure in a Patient With Loeys-Dietz Syndrome: A Case Report.

Inguinal hernia repair is one of the most frequently performed procedures in pediatric surgery. Treatment methods include classical open repair and laparoscopic approach. In this report we analyze a case of a 14-month-old boy with Loeys-Dietz syndrome treated for an inguinal hernia with laparoscopic percutaneous internal ring suturing (PIRS). Two weeks post-operatively the patient was diagnosed with a recurrence of the hernia complicated by an intestine strangulation. As a re-operation of the hernia, the Lichtenstein method was applied successfully. We analyzed the literature to determine the safety and possible contradictions of the PIRS procedure, with particular emphasis on patients with comorbidities such as connective tissue disorders. We conclude that in the PIRS procedure, despite its safety, feasibility and low complication rate in healthy patients, too few studies were made to draw similar conclusions for patients with comorbidities such as connective tissue disorders.

Case report: Diagnosis and surgical treatment of delayed traumatic diaphragmatic hernia with hepatothorax and enterothorax in a small dog.

An 8-year-old castrated male teddy bear dog presented to our clinic with a persistent cough. The sick dog suffered from vehicular trauma 6 months prior to the visit and had imaging and exploratory laparotomy. Imaging and exploratory laparotomy at the time showed no significant damage. We performed contrast radiography (barium gavage) on the sick dog. Based on the results of a complete contrast radiography (barium gavage), tubular shadows in the thoracic cavity were identified as the small intestine and cecum, and delayed traumatic diaphragmatic hernia with hepatothorax and enterothorax was confirmed with radiographs. Accordingly, the sick dog underwent general anesthesia, manual ventilation and diaphragmatic herniorrhaphy by standard ventral midline abdominal approach. Postoperatively, the dog was given analgesia and antibacterial treatment, and the liver biochemical indexes were monitored to prevent endotoxin. Postoperative radiographs revealed clear contours of thoracic and abdominal organs. The dog moved, ate, and urinated normally within 10 days of the surgery. This case provides a reference for a complete barium meal imaging procedure that clearly shows the position of the organs in the thoracoabdominal cavity after the occurrence of a delayed traumatic diaphragmatic hernia. This paper provides a practical reference for the diagnosis of delayed traumatic diaphragmatic hernia with hepatothorax and enterothorax.

Surgical Technique and Chronic Postoperative Inguinal Pain in Patients Undergoing Open Inguinal Hernioplasty in Portugal: A Prospective Multicentric Cohort Study.

INTRODUCTION: Evidence about the advantage of Lichtenstein's repair, the guidelines' recommended technique, is scarce regarding postoperative chronic inguinal pain (CPIP). The primary aim of this study was to compare CPIP in patients undergoing Lichtenstein versus other techniques. METHODS: Prospective multicentric cohort study including consecutive adults undergoing elective inguinal hernia repair in Portuguese hospitals (October - December 2019). Laparoscopic and mesh-free hernia repairs were excluded. The primary outcome was postoperative pain at three months, defined as a score of ≥ 3/10 in the European Hernia Society Quality of Life score pain domain. The secondary outcome was 30-day postoperative complications. RESULTS: Eight hundred and sixty-nine patients from 33 hospitals were included. Most were men (90.4%) and had unilateral hernias (88.6%). Overall, 53.6% (466/869) underwent Lichtenstein's repair, and 46.4% (403/869) were treated with other techniques, of which 83.9% (338/403) were plug and patch. The overall rate of CPIP was 16.6% and 12.2% of patients had surgical complications. The unadjusted risk was similar for CPIP (OR 0.76, p = 0.166, CI 0.51 - 1.12) and postoperative complications (OR 1.06, p = 0.801, CI 0.69 - 1.60) between Lichtenstein and other techniques. After adjustment, the risk was also similar for CPIP (OR 0.83, p = 0.455, CI 0.51 - 1.34) and postoperative complications (OR 1.14, p = 0.584, CI 0.71 - 1.84). CONCLUSION: The Lichtenstein technique was not associated with lower CPIP and showed comparable surgical complications. Further investigation as- sessing long term outcomes is necessary to fully assess the benefits of the Lichtenstein technique regarding CPIP.

Long-term patient-reported outcome measures (PROMs) after primary ventral or small midline incisional hernia repair.

BACKGROUND: Ventral hernia repair is a common elective surgical procedure lacking strong evidence for specific operative approaches. This study aimed to evaluate the outcomes of primary suture repair or polypropylene sandwich mesh repair for ventral hernias. The main outcome measures were the rate of hernia recurrence, and evaluation of long-term complications and patient-reported outcomes. METHODS: This retrospective cohort study evaluated patient perceived recurrence and pain in patients who had undergone a primary ventral hernia (epigastric, supraumbilical, or umbilical) repair or small (≤20 mm) midline incisional hernia repair 10 years after the procedure. Short-term follow-up occurred up to 6 weeks after the initial operation, while long-term follow-up included patients who were reviewed clinically or interviewed via telephone at or beyond 3 years after the procedure. RESULTS: Most (75/100, 75.0%) patients had an extra-peritoneal sandwich mesh repair. Short-term follow-up showed minimal pain and normal activities for all patients (97/97, 100%). Long-term follow-up (median 12 years [IQR 11-13]) was achieved in 95.9% (93/97) of patients with only a small number reporting a slight bulge (5/93, 5.4%) and intermittent mild discomfort (8/93, 8.6%). Nine patients (9/97, 9.3%) experienced hernia recurrence, diagnosed at a median of 26 months [interquartile range, IQR, 7-58] post-operatively. CONCLUSIONS: These findings suggest that an open sandwich mesh technique is a safe and effective method for repairing primary ventral hernias and small midline incisional hernias and is associated with favourable long-term patient-reported outcomes.

Misdiagnosis of a Drain-site Hernia Containing Fallopian Tube Fimbria on 18F-FDG PET/CT.

In a 55-year-old woman with sigmoid colon cancer, a subcutaneous mass in the left lower abdomen was incidentally found and gradually enlarged. For further diagnosis and staging, an 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography scan was performed, which revealed a subcutaneous mass in the left lower abdomen with mild uptake of 18F-FDG, suggesting the possibility of metastasis. However, post-surgery and pathological confirmation, this mass was diagnosed as a drain-site hernia containing fallopian tube fimbria, which is extremely rare but should be considered in the differential diagnosis of subcutaneous mass in the lower abdomen.

An Unusual Postoperative Complication Following Bilateral Inguinal Hernioplasty: A Pocket Hernia Case Report.

Inguinal hernias are the most common type of hernias in the groin, affecting 27% of the population, with a nine to 12 times higher incidence in men. The primary treatment for this condition typically involves a surgical procedure, with most surgeons opting for mesh placement through a laparoscopic approach. While this procedure is generally associated with low complication rates (primarily hematomas, seromas, and scrotal edema), there are some highly infrequent complications reported such as postoperative small bowel obstruction (SBO), estimated to occur in approximately 0.1%-0.5% of cases, most commonly during transabdominal preperitoneal (TAPP) repair. It is crucial to emphasize the importance of using skilled surgical techniques and adhering to established guidelines in postoperative patient care to minimize the risk of these complications. We describe a case of a 47-year-old male patient who underwent bilateral TAPP repair for inguinal hernias and subsequently experienced postoperative complications, including the development of a hematoma and SBO, requiring a re-intervention that evidenced a peritoneal pocket hernia.

A novel technique for NO.253 lymph node dissection and left colic artery preservation to avoid potential postoperative internal hernia in laparoscopic radical resection for rectal cancer.

BACKGROUND: The preservation of the left colic artery (LCA) has emerged as a preferred approach in laparoscopic radical resection for rectal cancer. However, preserving the LCA while simultaneously dissecting the NO.253 lymph node can create a mesenteric defect between the inferior mesenteric artery (IMA), the LCA, and the inferior mesenteric vein (IMV). This defect could act as a potential "hernia ring," increasing the risk of developing an internal hernia after surgery. The objective of this study was to introduce a novel technique designed to mitigate the risk of internal hernia by filling mesenteric defects with autologous tissue. METHODS: This new technique was performed on eighteen patients with rectal cancer between January 2022 and June 2022. First of all, dissected the lymphatic fatty tissue on the main trunk of IMA from its origin until the LCA and sigmoid artery (SA) or superior rectal artery (SRA) were exposed and then NO.253 lymph node was dissected between the IMA, LCA and IMV. Next, the SRA or SRA and IMV were sequentially ligated and cut off at an appropriate location away from the "hernia ring" to preserve the connective tissue between the "hernia ring" and retroperitoneum. Finally, after mobilization of distal sigmoid, on the lateral side of IMV, the descending colon was mobilized cephalad. Patients'preoperative baseline characteristics and intraoperative, postoperative complications were examined. RESULTS: All patients' potential "hernia rings" were closed successfully with our new technique. The median operative time was 195 min, and the median intraoperative blood loss was 55 ml (interquartile range 30-90). The total harvested lymph nodes was 13.0(range12-19). The median times to first flatus and liquid diet intake were both 3.0 days. The median number of postoperative hospital days was 8.0 days. One patient had an injury to marginal arterial arch, and after mobolization of splenic region, tension-free anastomosis was achieved. No other severe postoperative complications such as abdominal infection, anastomotic leakage, or bleeding were observed. CONCLUSIONS: This technique is both safe and effective for filling the mesenteric defect, potentially reducing the risk of internal hernia following laparoscopic NO.253 lymph node dissection and preservation of the left colic artery in rectal cancer surgeries.

Diaphragmatic Hernia With Secondary Pneumothorax Due to Intestinal Perforation After Thoracoabdominal Aortic Aneurysm Operation: A Case Report.

A male in his 70s with a history of artificial vessel replacement for a thoracoabdominal aneurysm had been treated non-operatively for adhesive bowel obstruction during the past two months. The initial symptom was nausea and the patient was transferred to our hospital because of diffuse abdominal pain. Computed tomography revealed pneumothorax, diaphragmatic hernia, and bowel perforation. A left thoracic drain was inserted and air and clear yellow fluid were drained. Secondary pneumothorax was presumably caused by intestinal perforation associated with diaphragmatic hernia. Although reported cases with secondary pneumothorax associated with diaphragmatic hernia and intestinal perforation are caused by trauma, this complication can occur postoperatively.

Quain Hernia Masquerading as Mesenteric Ischemia.

The case describes a rare instance of Quain hernia, a specific type of internal hernia where the bowel protrudes through a defect in the broad ligament. Broad ligament defects can either be congenital or acquired. Quain hernias are uncommon and difficult to diagnose due to nonspecific symptoms. We report a case of a Quain hernia initially diagnosed as mesenteric ischemia with small bowel gangrene. If a Quain hernia is suspected, immediate diagnostic laparoscopy is recommended, as it is an effective diagnostic tool and definitive management method, regardless of the specific type. During the laparoscopic procedure, it is crucial to thoroughly assess the contralateral broad ligament to identify any defects, which should be repaired prophylactically if found. Understanding their rare presentation and distinctive radiological features is vital for prompt diagnosis and appropriate management, highlighting the need to consider uncommon etiologies in acute abdominal cases to optimize patient outcomes.

Robotic-Assisted Laparoscopic Repair of Petit's Hernia With Preperitoneal Mesh.

Lumbar hernias are rare abdominal wall hernias that occur in the posterolateral abdominal wall. Intra-peritoneal or extra-peritoneal contents typically protrude through defects in one of two anatomical triangles. The superior lumbar triangle (Grynfeltt-Lesshaft triangle) is an inverted triangle bordered by the 12th rib superiorly, the internal oblique muscle laterally, and the erector spinae muscle medially. The inferior lumbar triangle (Petit's triangle) is an upright triangle bordered by the iliac crest inferiorly, the external oblique muscle laterally, and the latissimus dorsi muscle medially. Surgical repair has been described via open or laparoscopic approach. A 69-year-old male patient presented with right flank pain and swelling. He was involved in a motorcycle accident 10 months prior, which likely resulted in the development of a traumatic lumbar hernia which was demonstrated on the CT scan. The hernia was clinically incarcerated, and the defect contained the cecum and ileocecal valve. The defect was noted just superior to the iliac crest, by definition, making this an inferior lumbar hernia or a Petit's hernia. The hernia was repaired via robotic-assisted laparoscopic transabdominal approach. A peritoneal flap was created exposing the fascial defect. The fascia was primarily repaired with suture. The defect was reinforced with an 11.4 cm round Ventralight ST mesh in the preperitoneal space. The patient tolerated the procedure well with no acute complications. He was discharged the same day as an outpatient with appropriate pain control. Short-term follow-up demonstrated no recurrent hernia present and symptoms resolved. Lumbar hernias are a rare occurrence with no gold standard technique for repair. The benefits of the laparoscopic approach have been described over the open approach. This case report describes utilizing a minimally invasive approach to primarily repair a lumbar hernia defect while also reinforcing the hernia with mesh in the preperitoneal space.

Outcomes of Robotic Transabdominal Retromuscular Repair: 3-Year Follow-up.

Background: Our study addresses the gap in ventral hernia repair literature, regarding the long-term effectiveness of robotic transabdominal retrorectus umbilical prosthetic repair (r-TARUP) for primary and incisional ventral hernias. This study aimed to report the 3-year recurrence rates and overall patient outcomes including quality of life. Method: A retrospective review of prospective collected data analyzed 101 elective r-TARUP patients from August 2018 to January 2022. Data collected included demographics, hernia sizes, mesh types, postoperative outcomes and the European Hernia Society Quality of Life questionnaire (EuraHS-QoL) before and after surgery. Results: The average age of the group of patients was 53, having a mean body mass index (BMI) of 32 kg/m, with 54% incisional and 46% primary hernias, with mean length and width of 4.4 cm and 6.1 cm, utilizing synthetic 58% and bioabsorbable 42% mesh types. The majority were classified as Centers of Disease Control and Prevention (CDC) class I wounds. Postoperative complications included seroma (2%), hematoma (3%), which required surgical intervention, with no significant correlation to mesh type. A strong positive correlation was found between Transversus Abdominis Release (TAR) and increased length of hospital stay (correlation coefficient: 0.731, p < 0.001). Preoperative quality of life assessments demonstrated statistically significant improvements when compared to postoperative assessments at 3 years, with a mean (±SD) of 61.61 ± 5.29 vs. 13.84 ± 2.6 (p < 0.001). Mean follow up of 34.4 months with no hernia recurrence at 1 year and 3 recurrence at the 2-3 years follow up (3.2%). Conclusion: The r-TARUP technique has proven to be safe and effective for repairing primary and incisional ventral hernias, with a low recurrence rate during this follow up period with a noticeable improvement in quality of life (QoL).

Transmesenteric internal hernia: an unexpected adverse event induced by colonoscopy.

Transmesenteric internal hernia is an uncommon cause of small bowel obstruction that occurs when small bowel loops protrude through a mesenteric defect into the abdominal cavity. Herein, we present an unexpected case of colonoscopy-induced transmesenteric internal hernia. An 81-year-old male patient presenting with intermittent hematochezia and constipation had undergone a laparoscopic left nephrectomy for ureteral cancer. A colonoscopy was performed to identify the etiology of his symptoms. He complained of severe abdominal pain 2 h after the examination despite uneventful endoscopic procedures, including cold snare polypectomy. Contrast-enhanced computed tomography revealed a strangulated small bowel obstruction with a closed-loop formation outside the descending colon. The small bowel loop was incarcerated into the left retroperitoneal space. Emergency laparotomy detected small bowel loops that prolapsed into the nephrectomy pedicle via a descending mesenteric defect, developed during the laparoscopic left nephrectomy. The incarcerated small bowel was detached from the hernia and returned to its normal position, and the mesenteric defect was closed. He demonstrated an uneventful postoperative course, with no internal hernia recurrence after discharge. This case indicates the risk of transmesenteric internal hernia through inadvertently created mesenteric defects should be borne in mind, especially when performing colonoscopies in patients who underwent laparoscopic nephrectomies.

Small Bowel Obstruction Associated With Ureterocutaneous Fistula After a Radical Cystectomy: A Case Report.

This is a case report of a man in his 60s who was diagnosed with a small bowel obstruction due to an internal hernia caused by a ureterocutaneous fistula. Internal hernia caused by the ureter following urinary diversion is rare, posing challenges in preoperative diagnosis and carrying the risk of intraoperative injury due to the resemblance of a ureterocutaneous fistula to an adhesive band. The presentation and surgical management are discussed in this case report.

Diet and risk for hernia: a Mendelian randomization analysis.

Background: The relationship between dietary factors and hernias is currently unclear. Methods: The UK Biobank was used to extract dietary factors that were used as exposures, including intake of alcohol, non-oily fish, beef, fresh fruit, oily fish, salad/raw vegetables, dried fruit, coffee, cereal, salt, tea, water, cooked vegetables, cheese, Lamb/mutton, pork, poultry, processed meat, and bread. The FinnGen biobank was used to obtain GWAS data on hernias as outcomes. The main analysis of this study was performed using the weighted median, MR-Egger, and IVW methods. Cochran's Q test was utilized to assess heterogeneity. To find potential outliers, the MR-PRESSO method was used. Leave-one-out analysis was employed to assess the IVW method's robustness. Results: Alcoholic consumption per week (OR: 0.614; p = 0.00614) reduced the risk of inguinal hernia. Alcohol intake frequency (OR: 1.309; p = 0.0477) increased the risk of ventral hernia (mainly including incisional hernia and parastomal hernia). The intake of non-oily fish (OR: 2.945; p = 0.0214) increased the risk of inguinal hernia. Salt added to food (OR: 1.841; p = 0.00267) increased the risk of umbilical hernia. Cheese intake (OR: 0.434; p = 0.000536) and dried fruit intake (OR: 0.322; p = 0.00716) decreased the risk of ventral hernia, while cooked vegetable intake (OR: 4.475; p = 0.0380) increased the risk of ventral hernia. No causal relationships were found with hernias from other dietary factors. Conclusion: Inguinal, umbilical, and ventral hernias are all related to dietary factors.
