The Utilization of Laparoscopic Ventral Hernia Repair (LVHR) in Incarcerated and Strangulated Cases: A National Trend in Outcomes

INTRODUCTION

Early after its adoption, minimally invasive surgery had limited usefulness in emergent cases. However, with improvements in equipment, techniques, and skills, laparoscopy in complex and emergency operations expanded substantially. This study aimed to examine the trend of laparoscopy in incarcerated or strangulated ventral hernia repair (VHR) over time.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for laparoscopic repair of incarcerated and strangulated hernias (LIS-VHR) and compared over 2 time periods, 2014-2016 and 2017-2019.

RESULTS

The utilization of laparoscopy in all incarcerated or strangulated VHR increased over time (2014-2016: 39.9% (n = 14 075) vs 2017-2019: 46.3% (n = 18 369), P < .001). Though likely not clinically significant, demographics and comorbidities statistically differed between groups (female: 51.7% vs 50.0%, P = .003; age 54.5 ± 13.7 vs 55.4 ± 13.8 years, P < .001; BMI 34.9 ± 8.0 vs 34.6 ± 7.8 kg/m2, P < .001). Patients from 2017 to 2019 were less comorbid (18.9% vs 16.8% smokers, P < .001; 18.2% vs 17.3% diabetic, P = .036; 4.6% vs 4.1% COPD, P = .021) but had higher ASA classification (III: 43.3% vs 45.7%; IV: 2.5% vs 2.7%, P < .001). Hernia types (primary, incisional, recurrent) were similar in each group. Operative time (89.7 ± 59.3 vs 97.4 ± 63.4 min, P < .001) became longer but length-of-stay (1.4 ± 3.3 vs 1.1 ± 2.6 days, P < .001) decreased. There was no statistical difference in surgical complications, medical complications, reoperation, or readmission rates between periods.

CONCLUSION

Laparoscopic VHR has become a routine method for treating incarcerated and strangulated hernias, and its utilization continues to increase over time. Clinical outcomes have remained the same while hospital stays have decreased.

Investigation of the clinical efficacy of thiol-disulfide homeostasis, delta neutrophil index, and ischemia-modified albumin in cases of incarcerated and strangulated hernia

BACKGROUND

The treatment of patients presenting with the diagnosis of incarcerated and/or strangulated inguinal hernia is mostly surgery. If strangulation and necrosis are present, the need for laparotomy arises, which may increase the risk of morbidity. Currently, it is not possible to clearly determine whether there is bowel ischemia and necrosis before surgery. In this study, we aimed to investigate the clinical efficacy of the thiol-disulfide homeostasis, delta neutrophil index (DNI), and ischemia-modified albumin (IMA) parameters in incarcerated and strangulated hernia cases.

METHODS

Patients that presented to the general surgery outpatient clinic due to inguinal hernia or to the emergency department of the hospital with a preliminary diagnosis of incarcerated and/or strangulated hernia in April 2021-November 2021 were included in the study. The patients were divided into the following four groups: patients that underwent elective repair for inguinal hernia (Group 1), those who were followed up without surgery due to incarcerated hernia (Group 2), those who underwent hernia repair without bowel resection due to incarceration (Group 3), and those who underwent bowel resection due to strangulation (Group 4). Group 1 was defined as the control group, while Groups 2, 3, and Group 4 were evaluated as the incarcerated/strangulated hernia group. The demographic data of the patients, length of hospital stay, body mass index, comorbidities, medical history and physical examina-tion findings, radiological examinations, treatments applied, white blood cell (WBC) count, lactate, and DNI, thiol-disulfide and IMA parameters were evaluated.

RESULTS

The WBC count, disulfide/native thiol, disulfide/total thiol, and IMA values were significantly higher in the incarcerated/strangulated hernia group than in the control group, while the native thiol and total thiol values were higher in the latter than in the former (P<0.05). There was no statistically significant difference between the groups in terms of lactate (P>0.05), but the mean WBC count was higher in Group 4 compared to Group 1, and the mean DNI was significantly higher among the patients who underwent bowel resection and anastomosis than in those that were followed up and discharged (P<0.05).

CONCLUSION

We consider that the preoperative evaluation of the thiol-disulfide homeostasis, IMA, and DNI parameters in incarcerated/strangulated hernia cases can be an effective and easily applicable method in predicting difficulties that may be encountered intraoperatively and the surgical procedure to be applied to the patient.

Obturator Hernia in a 71-Year-Old Patient: A Diagnostic Challenge

An obturator hernia is a relatively rare form of pelvic hernia, wherein abdominal organs protrude through an opening in the pelvis known as the obturator foramen. The majority of patients with this condition present to the emergency room with symptoms of bowel obstruction. Due to the non-specific nature of these symptoms, making a preoperative diagnosis of obturator hernia can be challenging. Any delay in the diagnosis and treatment of this condition can lead to a significant risk of mortality. In this report, we present the case of a 71-year-old patient who presented to the emergency department complaining of lower abdominal pain and nausea. An abdominal X-ray revealed bowel dilation, and based on the patient's symptoms, a diagnosis of bowel obstruction was suspected. A CT scan of the abdomen and pelvis was performed to investigate the reason for bowel dilation, and the existence of an obturator hernia was confirmed.

Abdominal wall necrotizing fasciitis as a complication of strangulated hernia - an ominous consequence of a preventable scenario

The incidence rate of abdominal wall necrotizing fasciitis (NF) is low; however, it carries a high mortality rate. It can arise as a complication of a strangulated hernia, where a part of the intestine becomes trapped and deprived of its blood supply. Rarely, this can result in abdominal wall fasciitis, which carries a grim prognosis. Timely debridement, however, has been shown to yield improved outcomes. Here, we report our experience with a 53-y-old morbidly obese patient who presented with colicky abdominal pain lasting for 1 week, progressively worsening and becoming constant. She also exhibited symptoms of fever, constipation, vomiting and anorexia. Furthermore, there was an infected wound measuring 20 cm × 13 cm along the midline of the abdomen. Imaging studies revealed indications of small bowel obstruction. This case describes a unique presentation of strangulated incisional hernia complicated by NF of the anterior abdominal wall, successfully managed with surgery.

Emergency hernia repair: a retrospective cross-sectional study on the treatment modalities and adherence to guidelines in a tertiary public hospital

BACKGROUND

Emergency presentations of hernias can pose significant morbidity. In addition, providing optimal surgical intervention can be challenging due to patient and disease factors with multiple treatment modalities available. Recently there have been several guidelines written to help standardize practices in hernia management. The aim of our study was to review emergency hernia operations at our tertiary level teaching hospital, the method of repair and how this matched to international guidelines.

METHODS

We performed a retrospective chart review of all the patients who underwent emergency hernia surgery for strangulated/incarcerated hernias in our department over a 3-year period. Adherence to guidelines was assessed looking at appropriateness of mesh utilization, as well as the appropriateness of antibiotic usage.

RESULTS

A total of 184 cases from April 1st 2018 to March 31st 2021 were included. Of these hernias 12% contained necrotic or perforated bowel, 42% contained viable incarcerated bowel, and 45% contained just incarcerated fat. The compliance to the appropriate use of mesh overall was 85%, with a variation by hernia type. The global compliance to appropriate antibiotic therapy was high, at 89.7%. With antibiotic use compliance being very high in clean wounds (95.6%), and dirty wounds (100%). But lower in clean/contaminated or contaminated wounds (36.8%).

CONCLUSION

Compliance at our hospital was globally good. Areas of decreased compliance seem to be mostly regarding mesh use and antibiotic use in potentially contaminated fields and the concept of risk of bacterial translocation versus actual contamination, as well as in mesh use in smaller umbilical hernias.

Trends in Incisional and Ventral Hernia Repair: A Population Analysis From 2001 to 2021

Background Incisional and ventral hernias are highly prevalent, with primary ventral hernias occurring in approximately 20% of adults and incisional hernias developing in up to 30% of midline abdominal incisions. Recent data from the United States have shown an increasing incidence of elective incisional and ventral hernia repair (IVHR) and emergency repair of complicated hernias. This study examines Australian population trends in IVHR over a two-decade study period. Methods This retrospective study was performed using procedure data from the Australian Institute of Health and Welfare and population data from the Australian Bureau of Statistics captured between 2000 and 2021 to calculate incidence rates per 100,000 population by age and sex for selected subcategories of IVHR operations. Trends over time were evaluated using simple linear regression. Results There were 809,308 IVHR operations performed in Australia during the study period. The cumulative incidence adjusted for population was 182 per 100,000; this increased by 9.578 per year during the study period (95%CI = 8.431-10.726, p<.001). IVHR for primary umbilical hernias experienced the most significant increase in population-adjusted incidence, 1.177 per year (95%CI = 0.654-1.701, p<.001). Emergency IVHR for incarcerated, obstructed, and strangulated hernias increased by 0.576 per year (95%CI = 0.510-0.642, p<.001). Only 20.2% of IVHR procedures were performed as day surgery. Conclusions Australia has seen a significant increase in IVHR operations performed in the last 20 years, particularly those for primary ventral hernias. IVHR for hernias complicated by incarceration, obstruction, and strangulation also increased significantly. The proportion of IVHR operations performed as day surgery is well below the target set by the Royal Australasian College of Surgeons. With the increasing incidence of IVHR operations and an increasing proportion of these being emergent, elective IVHR should be performed as day surgery when it is safe.

Cecal Volvulus Through an Internal Hernia Created by an Elongated Fallopian Tube

Internal hernias result from abdominal viscera protruding through a congenital or acquired defect in the peritoneum or the mesentery of the abdominal cavity. They are less common than external hernias, and the overall incidence is rare. Internal hernias carry a high mortality rate if there is no immediate surgical intervention and can lead to complications such as bowel perforation, ischemia, and necrosis. There are multiple classifications, and a rare subtype identified in only a select few cases involves the fallopian tube. This case documents the development of a cecal volvulus due to the cecum herniating through an aperture created by a normal-appearing fallopian tube attaching to the retroperitoneum.  A 78-year-old female with multiple comorbidities was admitted for abdominal pain lasting 3-4 days, nausea, emesis, and poor oral tolerance. Computerized tomography imaging revealed a complete large bowel obstruction secondary to a cecal volvulus, and she was taken emergently for an exploratory laparotomy. Intra-operatively, a distended cecum was noted, herniated through a loop created by the right fallopian tube tethering its free end to the left pelvis. Upon decompression of the bowel, the fallopian tube released itself from the retroperitoneum. The cecum and right fallopian tube were noted to be ischemic and resected with an ileo-transverse anastomosis. Internal hernias that involve the fallopian tubes are a rare variation of an already uncommon condition. However, they should be included in the differential diagnosis when evaluating a female patient for intestinal obstruction since it can develop into a life-threatening condition that requires prompt surgical attention.

[Strangulation of the appendix in an inguinal hernia sac in children]

OBJECTIVE

To study the features of the clinic and treatment of children with infringement of the appendix in inguinal hernias in children.

MATERIAL AND METHODS

We observed 12 children with the localization of the appendix in the right inguinal hernia. Four of them had an infringement of the appendix: two with inguinal hernia, two with sliding inguinal and femoral hernias. To verify the diagnosis, we used clinical and laboratory examinations of children with restrained inguinal hernia, ultrasound and Doppler examination of the groin and scrotum, X-ray, morphological examination of surgical materials. 4 clinical observations are presented.

RESULTS AND DISCUSSION

Difficulties in diagnosing acute appendicitis in case of infringement of the appendix in inguinal hernias in children are associated with an atypical clinical picture, which proceeds under the mask of OZO. Testicular infarction was found in 2 children with strangulated inguinal hernia and necrosis of the appendix. Combined surgery with abdominal and herniatomical access for sliding restrained hernias in 2 children made it possible to perform a radical operation and avoid severe postoperative complications.

CONCLUSIONS

1. Infringement of the appendix in inguinal hernias in children is rare. 2. The clinical picture of the restrained appendix in the hernial sac proceeds under the mask of OZJ. 3. Operative access in the groin area when the appendix is infringed in the hernial sac is the operation of choice. 4. In case of infringement of the appendix with sliding hernias (inguinal and femoral), the operation of choice can be abdominal and herniatomical approaches.

Caecal Volvulus Presenting as the Obstructed Right Inguinal Hernia

Caecal volvulus is an uncommon cause of intestinal obstruction with varied clinical presentation. Surgical intervention without delay is considered the gold standard in its management. Strangulated inguinal hernia with caecal volvulus is a rarity. We report a case of a 55-year-old male with a history of long-standing right inguinal hernia, presented with the irreducibility of the hernia along with pain for one day. Clinically patient was diagnosed to have an obstructed inguinal hernia. On exploration, we found that there was a caecal volvulus in the hernia sac along with gangrene of the distal ileum, redundant sigmoid, and ascending colon. Resection and anastomosis of the gangrenous segment of the bowel were done along with herniorrhaphy and sigmoidopexy. Postoperatively patient improved without any complication.

Strangulated Falciform Hernia

Internal hernias are rare, and a delayed diagnosis can lead to dangerous complications. A 75-year-old male with no previous surgical history presented with right upper abdominal pain and vomiting. On examination, he had guarding in the right hypochondrium with a positive Murphy's sign. However, ultrasonography of the gall bladder was normal with dilated bowel loops. Contrast-enhanced CT (CECT) revealed a falciform hernia with evidence of obstruction. Segmental resection of the gangrenous ileum was done with a double-barrel stoma. Later on, stoma reversal was also done with no complications.

Anesthetic Management of a Patient with Dilated Cardiomyopathy and End-stage Renal Disease for Emergency Strangulated Hernia Repair Surgery

Dilated cardiomyopathy (DCMP) is a myocardial disease associated with dilatation of one or both the ventricles, impaired myocardial contractility, decreased cardiac output, and increased ventricular filling pressures. Patients with end-stage renal disease are dependent on renal replacement therapy to survive and often manifest with a variety of pathological organ dysfunction. We present a case of DCMP and chronic kidney disease posted for emergency reduction of strangulated umbilical hernia under general plus epidural anesthesia.

Strangulated Richter's incisional hernia presenting as an abdominal mass with necrosis of the overlapping skin. A case report and review of the literature

Although rare, clinicians must be alerted of Richter hernias in patients presenting with innocuous gastrointestinal obstruction symptoms, synchronous with an erythematous hernia. An incarcerated incisional hernia located in a previous laparoscopic insertion site further raises suspicion, while timely surgical management is essential to avoid bowel perforation or resection.
