OBJECTIVE
The study investigates the mechanical properties of a nickel-titanium shape memory alloy anal fistula clip (NiTi-AFC), studies the surgical method of treating anal fistula, and evaluates its clinical efficacy.
METHODS
The anal fistula clip was formed in nickel-titanium alloy with a titanium content of 50.0%-51.8%. The mechanical properties and chemical properties were tested. A total of 31 patients with anal fistula were enrolled between 1 January 2020 and 1 January 2023. All patients underwent internal orifice closure surgery using NiTi-AFC, and anorectal magnetic resonance or ultrasound was performed before surgery and 6 months after surgery for diagnosis and evaluation. Fistula cure rates, length of stay, perianal pain, and Wexner incontinence scores were retrospectively compared between patients treated with NiTi-AFC and patients treated with other surgical methods.
RESULT
NiTi-AFC has a density of 6.44-6.50 g·cm, with a shape-restoring force of 63.8 N. The corrosion rate of NiTi-AFC in 0.05% hydrochloric acid solution at atmospheric pressure and 20°C is approximately 6.8 × 10 g·(m·h). A total of 31 patients (male/female: 19/12, age: 43.7 ± 17.8 years) were included. Among them, 22.6% (7) had multiple anal fistula, 16.1% (5) had high anal fistula, and 48.3% (15) had perianal fistula Crohn's disease. In total, 12.9% (4/31) did not achieve primary healing, underwent fistula resection, and eventually recovered. A retrospective analysis showed that the fistula healing rate, length of stay, and anal pain of NiTi-AFC treatment were similar to those of other traditional surgeries, but the Wexner incontinence score was significantly lower.
CONCLUSION
NiTi-AFC has shape memory properties, corrosion resistance, superelastic effect, and surface cell adhesion. It is applied to internal orifice closure surgery of anal fistula, with good therapeutic effect, and can protect the anal function.

BACKGROUND
Anal fissure (AF) is the second most common anorectal complaint in healthcare settings. The presentation might be acute or chronic, characterised by severe pain with defaecation that persists for one to two hours. Non-surgical and surgical interventions are available based on the severity and persistence of the fissure.
OBJECTIVE
The aim of this article is to review the pathophysiology, clinical presentation and management of AF under current guidelines.
DISCUSSION
The aetiology of AF is unclear, although it is commonly associated with local trauma or associated chronic conditions. Acute AF is first treated with conservative therapy, including dietary fibre and sitz baths. Addition of topical nitrates, topical calcium channel blockers or botulinum toxin injection is indicated with failure of conservative treatment or at medical discretion. Surgical options are considered if AF persists despite treatment. Most present as hypertonic, but special consideration is needed for hypotonic or secondary presentations.

Milligan-Morgan hemorrhoidectomy combined with non-doppler hemorrhoidal artery ligation for the treatment of grade III/IV hemorrhoids: a single centre retrospective study.
BACKGROUND
Milligan-Morgan hemorrhoidectomy (MMH) is the most widely used surgical procedure because of its precise curative effect, but it has the disadvantages such as obvious postoperative pain and bleeding. To retrospectively evaluate the efficacy and safety of MMH combined with non-Doppler hemorrhoidal artery ligation (MMH + ND-HAL) for the treatment of grade III/IV hemorrhoids.
METHODS
We conducted a retrospective analysis of 115 patients with grade III/IV hemorrhoids, 53 patients had received MMH + ND-HAL, and the remaining 62 patients received MMH. We collected and compared demographic and clinical characteristics of both groups, including intraoperative blood loss, postoperative visual analog scale (VAS) for pain, analgesic consumption, postoperative bleeding, perianal incision edema, urinary retention, anal stenosis, anal incontinence incidence, recurrence rate (prolapse or bleeding), and patient satisfaction.
RESULTS
The VAS pain score of the first postoperative defecation and at the postoperative 12 h, 1 day, 2 days, 3 days, and 7 days, as well as the total analgesic consumption within 7 days, for the MMH + ND-HAL group were lower than those for the MMH group (P < 0.05). The intraoperative blood loss, the incidence of postoperative bleeding, perianal incision edema, and urinary retention in the MMH + ND-HAL group was lower than that in the MMH group (P < 0.05). No anal stenosis or anal incontinence occurred in either group. At follow-up by telephone or outpatient 12 months after surgery, the recurrence rate (prolapse or bleeding) was lower in the MMH + ND-HAL group than in the MMH group (P < 0.05), and satisfaction was higher in the MMH + ND-HAL group than in the MMH group (P < 0.05).
CONCLUSIONS
MMH + ND-HAL was a satisfactory surgical modality for treating III/IV hemorrhoids.

Comparative Study
BACKGROUND Chronic anal fissure is a common condition that causes pain and discomfort and has a significant impact on quality of life. When conservative management fails, surgical sphincterotomy can be successful. This retrospective study from a single center in Turkey included 188 patients with chronic anal fissures and aimed to compare outcomes from open and closed sphincterotomy. MATERIAL AND METHODS This retrospective study included 188 patients treated with lateral internal sphincterotomy (LIS) for chronic anal fissure between January 2015 and December 2021 in our hospital. Open LIS procedure was performed in 91 patients and closed LIS was performed in 97 patients. Demographic characteristics, postoperative complications, and recurrence were compared for these 2 methods. RESULTS Of the 188 patients included in the study, 47.9% were women and 52.1% were men. The mean age was 42.9 (20-84) years. In the open LIS group, recurrence occurred in 2 patients (2.19%), and no incontinence was observed. In the closed LIS group, recurrence occurred in 3 patients (3%; P=0.703), and incontinence developed in 5 patients (5.15%; P=0.035). CONCLUSIONS Comparing the 2 methods used in chronic anal fissure surgery, and considering the recurrence and risk of incontinence, the most feared outcome by the patient and surgeon, open LIS stands out as a superior technique, especially in young male patients.

Review
Perianal Paget's disease (PPD) is a rare malignant cutaneous tumor. This paper reported a case of PPD complicated by lung adenocarcinoma and anal canal cancer. The patient, a 76-year-old female, had been experiencing recurrent lower abdominal pain and perianal pruritus for the past 5 years. Upon physical examination, a cauliflower-like neoplasm in size of 5 cm×6 cm was observed on the right perianal skin, with local skin ulceration and a small amount of fluid discharge. The left perianal skin was also involved. In thoracoknee position, a hard mass was palpable in the rectal submucosa at 5-6 points 2 cm from the anal verge. Chest CT revealed multiple lesions in both lungs, indication of metastatic tumors. Further evaluation with fluorodeoxyglucose positron emission tomography and computed tomography (FDG-PET/CT) indicated multiple hypermetabolic nodules in the lungs, hypermetabolic lymph nodes throughout the body, early FDG uptake in a small patch of skin on the left hip, and increased FDG uptake in the anorectal region. Histopathological examination confirmed the diagnosis of lung adenocarcinoma. This resulted in the patient being diagnosed with PPD, lung adenocarcinoma, anal canal cancer, and systemic multiple lymph node metastasis. The combination of PPD with gastrointestinal tumors and other metachronous malignant tumors is highly prevalent. Colonoscopy, FDG-PET/CT, histopathology, and immunohistochemistry play crucial roles in early identification of local lymph node and distant involvement, facilitating the evaluation of potential malignant tumors and differential diagnosis. Treating methods for PPD are currently diverse, including postoperative combined or single chemotherapy, radiotherapy, targeted therapy, and photodynamic therapy. As trerapeutical options continue to develop, the extent and efficacy of surgery need to be reassessed.

The aim of this study was to investigate the clinical characteristics, psychological status, sleep quality, and quality of life of patients with functional anorectal pain (FAP). The study also assessed the treatment efficacy of paroxetine in alleviating FAP symptoms. A retrospective comparative study of forty-three patients with FAP who were first treated with an anal plug compound glycolate suppository versus paroxetine combined with anal plug compound glycolate suppository between November 2021 and August 2022. Pain, quality of life, depression, anxiety and sleep quality were assessed before and after treatment by the Chinese version of the Short-Form McGill Pain Questionnaire-2 (SF-MPQ-2), Health-related quality of life scale (The 12-Item Short-Form Health Survey, SF-12), 17-item Hamilton Depression Rating Scale (HDRS), 14-item Hamilton Anxiety Scale (HAMA), and Pittsburgh Sleep Quality Index (PSQI). A total of 46.5% of patients with FAP were found to have anxiety symptoms (HAMA ≥ 7), 37.2% of patients with FAP were found to have depressive symptoms (HDRS ≥ 8). A total of 32.6% of patients with FAP had sleep disorders (PSQI > 10). Within 1 week after drug withdrawal, the short-term efficacy rate of oral paroxetine was 95.5%. After treatment, the symptom pain score (VAS) and sleep score were lower than those before treatment (P < 0.01). In the areas of vitality (VT), Social Functioning (SF), and Mental Health (MH), the difference between the pre-treatment and 8 weeks posttreatment scores of the study group and the control group was statistically significant (P < 0.05). FAP patients have obvious symptoms of anxiety and depression, and the incidence of sleep disturbance is prevalent. Paroxetine, a typical serotonin reuptake inhibitor (SSRI), was able to alleviate depression, anxiety, and pain symptoms in FAP, which might have clinical application prospects.

Effects of epidurally administered dexmedetomidine and dexamethasone on postoperative pain, analgesic requirements, inflammation, and oxidative stress in thoracic surgery.
The aim of this study was to compare the effects of dexmedetomidine and dexamethasone as adjuvants to preoperative epidural administration of local anesthetic (ropivacaine) in thoracic surgery on the postoperative level of pain, use of analgesics, inflammation, and oxidative stress. The study enrolled 42 patients who underwent elective thoracic surgery in a one-year period at the University Hospital Dubrava (Zagreb, Croatia). Based on a computer-generated randomization list the patients were assigned to the dexmedetomidine ( = 18) or dexamethasone ( = 24) group. Postoperatively, patients of dexmedetomidine group reported lower pain (VAS value 1 h post surgery, 3.4 ± 2.7 5.4 ± 1.8, dexmedetomidine dexamethasone, < 0.01) and had lower anal-gesic requirements in comparison with dexamethasone group. Thus, dexmedetomidine in comparison with dexamethasone was more efficient in lowering pain and analgesia requirements 24 h after the surgery. On the contrary, dexamethasone had better anti-inflammatory properties (CRP level 24 h post surgery, 131.9 ± 90.7 26.0 ± 55.2 mg L, dexmedetomidine dexamethasone, < 0.01). Both dexmedetomidine and dexamethasone exhibited antioxidant effects, however, their antioxidant properties should be further explored. The results of this study improve current knowledge of pain control in thoracic surgery.

BACKGROUND
A long-standing (over 10 years) anal fistula is considered a fundamental cause of fistula-associated mucinous adenocarcinoma (FAMC). Perianal abscesses and anal fistulas are two sequential phases of the same anorectal infectious process. We experienced a case of FAMC which developed 3 years after the treatment of a perianal abscess.
CASE PRESENTATION
A 68-year-old woman was admitted to our hospital because of progressive anal pain and a palpable tumor. She had a history of undergoing a drainage operation for a perianal abscess 3 years previously. A 15 × 15-mm tumor at the former drainage site was identified; transanal ultrasonography showed an intersphincteric fistula connecting to the tumor. A biopsy taken from the tumor demonstrated mucinous adenocarcinoma; the tumor was diagnosed as FAMC. Laparoscopic abdominoperineal resection was performed. Histopathology showed highly dysplastic cells lining the lumen of the anal fistula and poorly differentiated mucinous adenocarcinoma proliferating in the dermis and epidermis in the distal aspect of the fistula.
CONCLUSIONS
FAMC can develop within fewer than 3 years after the development of a perianal abscess and anal fistula.

BACKGROUND
Robotic resection using the natural orifice specimen extraction surgery I-type F method (R-NOSES I-F) is a novel minimally invasive surgical strategy for the treatment of lower rectal cancer. However, the current literature on this method is limited to case reports, and further investigation into its safety and feasibility is warranted.
AIM
To evaluate the safety and feasibility of R-NOSES I-F for the treatment of low rectal cancer.
METHODS
From September 2018 to February 2022, 206 patients diagnosed with low rectal cancer at First Affiliated Hospital of Nanchang University were included in this retrospective analysis. Of these patients, 22 underwent R-NOSES I-F surgery (R-NOSES I-F group) and 76 underwent conventional robotic-assisted low rectal cancer resection (RLRC group). Clinicopathological data of all patients were collected and analyzed. Postoperative outcomes and prognoses were compared between the two groups. Statistical analysis was performed using SPSS software.
RESULTS
Patients in the R-NOSES I-F group had a significantly lower visual analog score for pain on postoperative day 1 (1.7 ± 0.7 2.2 ± 0.6, = 0.003) and shorter postoperative anal venting time (2.7 ± 0.6 3.5 ± 0.7, < 0.001) than those in the RLRC group. There were no significant differences between the two groups in terms of sex, age, body mass index, tumor size, TNM stage, operative time, intraoperative bleeding, postoperative complications, or inflammatory response ( > 0.05). Postoperative anal and urinary functions, as assessed by Wexner, low anterior resection syndrome, and International Prostate Symptom Scale scores, were similar in both groups ( > 0.05). Long-term follow-up revealed no significant differences in the rates of local recurrence and distant metastasis between the two groups ( > 0.05).
CONCLUSION
R-NOSES I-F is a safe and effective minimally invasive procedure for the treatment of lower rectal cancer. It improves pain relief, promotes gastrointestinal function recovery, and helps avoid incision-related complications.

Review
PURPOSE
Pudendal neuropathy is an uncommon condition that exhibits several symptoms depending on the site of nerve entrapment. This study aims to evaluate the efficacy of pudendal nerve neurolysis (PNN) in improving lower urinary tract symptoms, anal and/or urinary incontinence, and sexual dysfunctions.
MATERIALS AND METHODS
A systematic literature search was performed on 20 May 2023 using Scopus, PubMed, and Embase. Only English and adult papers were included. Meeting abstracts and preclinical studies were excluded.
RESULTS
Twenty-one papers were accepted, revealing significant findings in the field. The study identified four primary sites of pudendal nerve entrapment (PNE), with the most prevalent location likely being at the level of the Alcock canal. Voiding symptoms are commonly exhibited in patients with PNE. PNN improved both urgency and voiding symptoms, and urinary and anal incontinence but is less effective in cases of long-standing entrapment. Regarding sexual function, the recovery of the somatic afferent pathway results in an improvement in erectile function early after neurolysis. Complete relief of persistent genital arousal disorder occurs in women, although bilateral PNN is necessary to achieve the efficacy. PNN is associated with low-grade complications.
CONCLUSIONS
PNN emerges as a viable option for addressing urinary symptoms, fecal incontinence, erectile dysfunction, and female sexual arousal in patients suffering from PNE with minimal postoperative morbidity.
