The impact of electrocautery method on post-operative bleeding complications after non-newborn circumcision and revision circumcision

Sutureless circumcision using monopolar diathermy and 2-octyl cyanoacrylate is safe and effective in a cohort of 634 post-neonatal prepubescent boys

BACKGROUND

Circumcision is the most commonly performed surgical procedure in the world, with one-third of males circumcised globally. Post-neonatal, prepubescent sutured circumcision demonstrates complication rates ranging from 1.7% to 9.1%. We have previously reported that 2-octyl cyanoacrylate (2-OCA, Dermabond, Ethicon) primary circumcision (PC) and circumcision revision (CR) in prepubescent children demonstrated superior cosmesis, shorter operating room (OR) times and cost savings.

OBJECTIVE

The aim of our study is to evaluate complication and reoperation rates with a scalpel-free and suture-less technique for primary circumcision (PC) and circumcision revision (CR) using 2-OCA.

METHODS

Following IRB approval, we conducted a retrospective review of all boys at our institution who underwent PC or CR using 2-OCA and monopolar diathermy between January 2014 and January 2021. All procedures were performed by a single surgeon. The technique is outlined in the figure below. No aligning sutures or instruments were used in this process. Patients that required sutures or compressive dressings based on age or associated anomalies were excluded from analysis. We obtained all returns to our system within 30 days of the procedure and returns to the OR during the study period using the REDCap database.

RESULTS

Of 1107 procedures performed during the study period, 634 procedures (479 PC and 155 CR) met inclusion criteria. Median age was 12 months (range 3 months-10.4 years) with minimum follow up of 1 year. There were 3 patients (0.47%) that returned to system within 30 days for surgical site bleeding, and one patient (0.15%) required surgical intervention within 30 days. Nine patients required reoperation after 30 days, five (0.8%) for iatrogenic phimosis, 3 (0.5%) for redundant prepuce and 1 for keloid formation. We observed an overall complication rate of 1.3% (6/634) and reoperation rate of 1.6% (10/634).

DISCUSSION

Since FDA approval in 1998, 2-OCA has been widely adopted as a replacement for sutures in tension-free wounds. However, it has yet to gain widespread use for circumcision given concerns for wound dehiscence and surgical site bleeding. This study demonstrates that a scalpel-free and suture-less technique demonstrates complication and reoperation rates are lower than reported circumcision using scalpel and sutures. Limitations include retrospective design, single surgeon experience, and REDCAP database only identifying patients with complications that required a return to system.

CONCLUSION

Our technique for suture-less circumcision using 2-OCA offers superior cosmesis, shorter OR times, cost savings, and a lower complication rate (1.3%) compared to sutured circumcision (>1.7%) reported in post-neonatal prepubescent boys.

Comparing the effects of current circumcision techniques on dorsal root ganglia: an experimental study

Background

Circumcision is a surgical removal process of the preputium. Surgical excision and electric current cause neurodegeneration in the excised tissue-related neural network. This study investigates if circumcision and current surgical methods would cause histopathological changes in the penile tissue innervating pudendal nerve dorsal root ganglia.

Results

Vascular congestion occluded the microvessels, and degenerative changes were detected in postexcised penile tissue. Neuronal angulation, cytoplasmic condensation, nuclear shrinkage, and condensed nuclei were observed in the pudendal nerve ganglia. Moreover, the degenerated neuron (DN) densities of the pudendal nerve ganglia were 5 ± 2, 98 ± 22, 1093 ± 185, 236 ± 43 and 151 ± 19 in the control, the surgical circumcision, the monopolar cautery, the bipolar cautery and the thermocautery groups, respectively.

Conclusions

Although only the pudendal nerve endings are affected secondary to prepusium excision another pudendal axons can be damaged during bleeding control with cautery, the destruction of the neuron that sends this axon initiates a general inflammation in that ganglion. As a result, there may be a somatosensitive innervation defect in extrapenile tissues innervated by this ganglion. High-voltage electric devices should not be used unless obligatory.

Management of post-circumcision necrosis of the penis: the medicolegal aspect

PURPOSE

To perform a medical evaluation of penile necrosis causes and treatment approaches by examining patients who had penile necrosis after circumcision surgery.

METHODS

A total of 24 patients with penile necrosis after circumcision surgery, who presented at various hospitals in Turkey between September 2003 and April 2013 and whose cases were being reviewed at the Institution of Forensic Medicine with regard to malpractice, were evaluated retrospectively.

RESULTS

The mean age of the patients was 5 ± 3.7 years, and the mean time of the necrosis diagnosis after circumcision was 5.2 ± 6.3 days. In etiologic terms, the predictive factors were monopolar cautery use in ten (41.6%) patients, post-circumcision infection in eight (33.3%), compartment syndrome due to post-circumcision dressing in three (12.5%), local anesthetic agent used for dorsal nerve blockage in two (8.3%), and methemoglobinemia in one (4.1%) patient. The first approaches to necrosis treatment were surgical intervention in 15 (62.5%) patients, hyperbaric oxygen treatment (HBOT) in 6 (25%), the conservative approach in 2 (8.3%), and HBOT plus surgical intervention in 1 (4.1%) patient.

CONCLUSION

Penile necrosis is a preventable complication that requires early intervention. The current study will be helpful in preventing penile necrosis and in guiding surgeons in approaches following its occurrence.

Oxidative and histopathological effects of the application of electrosurgical devices to the penile tissue of rats

INTRODUCTION

This study was performed to evaluate the oxidative and histopathological changes that occur following the application of electrosurgical devices (monopolar or bipolar cautery) to penile tissue.

MATERIAL AND METHODS

Eighteen Wistar albino male rats were randomly distributed into three groups. In the control group (CG, n = 6), all penile tissues were sampled without any additional process following the administration of anesthesia. In the monopolar cautery group (MPG, n = 6), a 15-W cauterization process lasting 5 s was performed on an approximately 2 mm² area of the ventral side of the penile shaft, 0.5 cm proximal to the edge of the glans in the midline. Bipolar cautery was practiced in the third group (BPG, n = 6) using the same techniques outlined in the previous statement. Penile tissues consisted of the cautery application area, the edge of the glans, and dorsal side of the penis and were sampled after 90 min; then, histopathological evaluation and biochemical examination involving malondialdehyde (MDA), nitric oxide (NO), and superoxide dismutase (SOD) measurements were performed.

RESULTS AND DISCUSSION

Histopathologically, the MPG and BPG demonstrated increased inflammation, fibrosis, and epithelial loss in the urethra in the areas to which cautery was applied as compared to the CG (P < 0.05). The vascular structures of the corpus cavernosa were significantly decreased in the cautery application area of both the MPG and the BPG as compared to the CG (P < 0.05). In the Masson's trichrome stained samples, significant collagen deposition was observed in the cautery application area both in the MPG and the BPG as compared to the CG (P < 0.05). However, S-100 staining was decreased in these groups as compared to the CG (P < 0.05). S-100 staining was also decreased in the MPG as compared to the BPG on the edge of the glans (P < 0.05). Biochemically, MDA values were significantly increased in the MPG as compared to the CG and the BPG (P < 0.05).

CONCLUSION

Monopolar and bipolar cautery both did cause oxidative changes and triggered inflammatory, vascular, and peripheral nerve alterations in the cautery application area while bipolar cautery did not cause any distant effects.
