Risk factors and clinical impact of seroma formation following laparoscopic inguinal hernia repair: a retrospective study

BACKGROUND

Although laparoscopic inguinal hernia repair (LIHR) has advantages over open surgery, postoperative seroma formation remains an issue. This study aimed to investigate the risk factors and clinical outcomes of seroma formation in patients undergoing LIHR.

METHODS

From January 2016 to March 2023, clinical data of patients who underwent LIHR were retrospectively analyzed. Patients who developed seroma and those who did not were classified into the seroma and non-seroma groups, respectively. The demographic and clinical characteristics were compared between the two groups. Univariate and multivariate logistic regression analyses were performed for variables of interest. The receiver operating characteristic curve was used to evaluate the risk factors of the binary logistic model, and the cutoff value for each risk factor was obtained.

RESULTS

Data of 128 patients were evaluated. Compared with patients in the non-seroma group, those in the seroma group had a higher body mass index (BMI) (P < 0.001), more direct hernias (P < 0.001), larger hernial orifice size (P < 0.001), more laparoscopic total extraperitoneal hernioplasty (TEP) (P < 0.001), more frequent reduction of hernial sac (P = 0.011), and lower preoperative serum albumin level (PSAL) (P < 0.001). Multivariate logistic regression analyses performed on these variables showed that high BMI (P = 0.005), large hernial orifice (P = 0.001), TEP (P = 0.033), and low PSAL (P = 0.009) were risk factors for seroma formation. Compared with the non-seroma group, the seroma group exhibited a higher numerical rating scale score for postoperative pain (P < 0.001), and longer hospital stays (P = 0.032).

CONCLUSIONS

BMI (> 24.5 kg/m2), hernial orifice size (> 2.5 cm), TEP, and PSAL (< 32.5 g/L) were independent risk factors of postoperative seroma formation in patients who underwent LIHR. Although most seromas resolve spontaneously without surgical intervention, seroma formation results in increased patient pain and prolonged hospital stay.

HIV patient with prolonged infection after hemicolectomy and repair of complicated hernia. Mini-review of a rare successful surgical outcome

Introduction and importance

Surgical site infection (SSI) is an inevitable occurrence in bowel perforation with faecal soiled hernia wound(s) especially in retroviral patients. Unfortunately, the increased antibiotics and wound care demands do not prevent delayed healing, increased risk of hernia recurrence, or multiple surgeries to control the infection. The standard open or endo-laparoscopic Mesh repairs are either deferred or avoided with alternative tissue-based hernia repairs after bowel surgery. The reported success of open tissue-based repairs remains mixed. Nylon monofilament that have been used in infected wounds was chosen for the patient in anticipation of wound infection.

Case presentation

A 48-year-old man presented with a 7-days complicated hernia at the emergency unit, Margaret Marquart Catholic Hospital. Clinical examination revealed signs of shock, intestinal obstruction, and peritonism, laboratory investigation was remarkable of anaemia, septicaemia, deranged renal function, and positive retroviral test. He had concurrent right hemicolectomy and nylon darn after optimisation. The outcome we evaluated after surgery included postoperative pain, scrotal collection, anastomotic breakdown, postoperative analgesic use, wounds infection, prolonged hospital stays, recurrence, and the need for a second surgery. Though he developed prolonged deep SSI, he has intact hernia repair after 6-years.

Clinical discussion

The postoperative critical clinical events presented in this case were unexpected but might have been precipitated by his retroviral status. Thus, a weight loss of over 13 kg within 2 weeks was highly unusual. Furthermore, the positive retroviral status couple with the perforated caecum and soiled peritoneum was the cause of the surgical site infection.

Conclusion

Nylon darning in a retro-positive patient developing prolonged SSI appeared beneficial. It should be considered in patients with anticipated long period wound infection.

•

Surgical site infection is a challenge in hernias with perforated viscus after repair.

•

Current standard modalities of hernia repairs are used in such patient's infection are not anticipated.

•

Patient with retroviral infection and wound contamination requires a different approach to ensure the intact repair.

•

Nylon darn, one of the methods was used with success.

•

Our patient with a prolonged infection after surgery and a 5-year post-repair success are a first of the kind reported.

Amyand's hernia- outcome of nylon darn repairs after complicated appendix surgeries in a district hospital: case series

INTRODUCTION

Complicated appendix is a least expected sac content of inguinal hernias that always require appendix surgery and hernia repair. The current recommendations for posterior wall repairs however, continue to attract conflicting views as to which modality gives the best outcome in infected surgical wounds. New posterior wall repair methods with properties to withstand surgical site infections, minimise hernia recurrence, affordable and easy skill to acquire with a potential to be widely adopted are continuosly sort.

AIM

To determine the surgical outcomes of complicated Amyand Hernias repaired using the open tissue base Nylon Darn posterior wall re-enforcement method.

METHOD

A retrospective review of medical records of patients who had surgery for emergency inguinal hernia with intra-operative confirmation of complicated appendix in the hernia sac from January 2015 to December 2020 at the Margaret Marquart Catholic Hospital, Kpando were included. Data on age, sex, clinical presentation, surgical procedure, intra-operative findings, post operative complications were captured and presented as descriptive statistics.

RESULTS

Twelve out of 286(4.6%) repairs were complicated Amyand Hernias in patients aged 6weeks to 76-years{median age 54.5-years}. Most of them were adults, long-standing hernias. All diagnosis were made on-table. Surgical site infections was the most frequent complication in types III and IV AHs which resolved with antibiotic treatment.

CONCLUSION

The incidence of complicated AHs is higher and should be anticipated in surgeries for long-standing complicated inguinal hernias. Even though complications were significantly associated with longer hospital stay, no second procedure or mortality was recorded.
