Outcomes from laparoscopic versus robotic mesh removal after inguinal hernia repair

Inguinal hernia recurrence after laparoscopic mesh removal for chronic pain: a single-center experience with 11 years of practice

INTRODUCTION

Up to 12% of patients undergoing minimally invasive inguinal hernia repair may develop chronic postoperative inguinal pain (CPIP), possibly explained by the presence of mesh. Recent studies reported that laparoscopic mesh removal is feasible and safe. However, the risk of a hernia recurrence is unknown. This observational study describes the rate of hernia recurrence and evolution in pain score following laparoscopic mesh removal for CPIP after preperitoneal inguinal hernia repair.

METHODS

Prospectively collected questionnaires and operative notes of consecutive patients undergoing a laparoscopic mesh removal for CPIP in our center of expertise between November 2011 and July 2022 were studied. Pain scores were quantified using the Numeric Pain Rating Scale (NRS, 0-10). The presence of a hernia recurrence was based on patient history and clinical findings.

RESULTS

A total of 89 patients underwent laparoscopic mesh removal, and data of 83 patients (93% response rate) were available for analysis. Median decrease in pain score (NRS) after mesh removal was 4 (range + 2 to - 9). After a median 4.3 years follow up period, a hernia recurrence was present in 18 patients (21.7%). Of these, eight were symptomatic requiring correction using a Lichtenstein repair with a favorable outcome whereas a wait-and-see approach was successfully followed in the remaining 10 patients.

CONCLUSION

Laparoscopic mesh removal for CPIP following preperitoneal inguinal hernia repair resulted in an inguinal hernia recurrence in one of five patients requiring remedial surgery in one in ten patients. This knowledge may inform the preoperative counseling process.

Initial experience of minimally invasive mesh explantation for inguinodynia

BACKGROUND

Chronic pain after minimally invasive inguinal hernia repair with mesh can have debilitating effects on quality of life (QOL), limiting daily activities and ability to work. Many medical and surgical options for treatment have been proposed, however there is no consensus on the role of mesh explantation in the management of these patients.

METHODS

We performed a retrospective review of all patients who underwent groin mesh removal by robotic or laparoscopic approach from July 2012 to July 2023 at our institution. Patients were interviewed post-operatively to determine their overall pain scores and QOL was assessed using the Carolinas Comfort Scale (CCS) Questionnaire. Patient characteristics, operative times, pre-operative imaging techniques and analgesia use was also recorded.

RESULTS

Twenty-two patients underwent groin mesh removal for chronic pain, including 12 robotic and 10 laparoscopic operations. The mean pre-operative pain score in all patients was 7.6/10 compared to 4.0/10 post-operatively. The mean post-operative CCS score was 24, indicating moderate discomfort. Four patients demonstrated CCS scores <11 indicating no discomfort and no patients demonstrated CCS scores >90, indicating severe debilitating discomfort. The majority of patients had a reduction or total cessation of analgesia intake post-operatively.

CONCLUSION

Both laparoscopic and robotic mesh explantation for treatment of chronic pain post-inguinal hernia repair is safe and effective in achieving a reduction in pain and reducing the need for long-term analgesia.

Directed cutaneous neurectomy for cutaneous neuralgia

BACKGROUND

Cutaneous neuralgia (CN) is a common challenge for surgical consultation. This report describes directed cutaneous neurectomy (DCN) for persistent CN.

METHODS

From 2010 through 2022, DCN was performed 112 times in 100 patients. All had complete temporary relief of CN by outpatient percutaneous proximal blockade. DCN involved a successful proximal blockade with blue dye added to the injectate, and all blue stained tissue was excised. The site of DCN included groin (49 patients), abdomen (38 patients), chest (7 patients), extremity (4 patients), or skull (2 patients). Relief was judged continuous (C), none (N), or temporary (T).

RESULTS

Pain relief was C in 82 patients (27 ​± ​20 ​mo), N in 6 patients, and T in 12 patients (22 ​± ​2 ​mo). The presence of microscopic nerve fibers (46 patients) or mesh (42 patients) did not affect outcome. A second DCN was done in two N patients, followed by C relief. A second DCN was done in seven T patients, and a third DCN was done in three T patients after recurrent CN.

CONCLUSIONS

Refractory CN can usually be successfully treated by DCN.

Patients With Systemic Reaction to Their Hernia Mesh: An Introduction to Mesh Implant Illness

In our practice, we have noticed an increased number of patients requiring mesh removal due to a systemic reaction to their implant. We present our experience in diagnosing and treating a subpopulation of patients who require mesh removal due to a possible mesh implant illness (MII). All patients who underwent mesh removal for indication of mesh reaction were captured from a hernia database. Data extraction focused on the patients' predisposing medical conditions, presenting symptoms suggestive of mesh implant illness, types of implants to which reaction occurred, and postoperative outcome after mesh removal. Over almost 7 years, 165 patients had mesh removed. Indication for mesh removal was probable MII in 28 (17%). Most were in females (60%), average age was 46 years, with average pre-operative pain score 5.4/10. All patients underwent complete mesh removal. Sixteen (57%) required tissue repair of their hernia; 4 (14%) had hybrid mesh implanted. Nineteen (68%) had improvement and/or resolution of their MII symptoms within the first month after removal. We present insight into a unique but rising incidence of patients who suffer from systemic reaction following mesh implantation. Predisposing factors include female sex, history of autoimmune disorder, and multiple medical and environmental allergies and sensitivities. Presenting symptoms included spontaneous rashes, erythema and edema over the area of implant, arthralgia, headaches, and chronic fatigue. Long-term follow up after mesh removal confirmed resolution of symptoms after mesh removal. We hope this provides greater attention to patients who present with vague, non-specific but debilitating symptoms after mesh implantation.
