Persistent Ostomy Following Percutaneous Endoscopic Gastrostomy Removal: Treatment Strategies.

PURPOSE OF REVIEW: The purpose of this article is to review available literature on management of persistent ostomy following PEG tube removal. We will discuss the incidence of persistent gastrocutaneous fistula (GCF) following PEG tube removal, risk factors for their development, and management strategies that have been proposed and their efficacy. RECENT FINDINGS: The use of over the scope clips (OTSC) have evolved recently in the management of gastrointestinal bleeding, perforation, and fistula closures. OTSC has become more readily available and proven to be effective and safe. Suturing devices have shown promising results. Persistent gastrocutaneous fistula following PEG removal is a rare yet serious complication that can lead to continuous skin irritation and leakage of gastric contents and acid. There are several postulated risk factors but the most important of these is duration of placement. Management can include medical therapy which has recently been shown to be somewhat effective, endoscopic therapy and surgery as a last resort. Overall, the data on GCFs is limited and further study with larger sample size is needed.

Closure of Gastrocutaneous Fistula Following Bariatric Surgery: a Systematic Review.

Gastrocutaneous fistula (GCF) is a devastating complication that can arise after bariatric and metabolic surgery (BMS). This systematic review examines the success rate of closure techniques of GCF. A systematic search was conducted across MEDLINE, Embase and Cochrane databases to identify studies which reported on closure techniques of GCF after BMS in adults. Thirty-three studies (n = 108 patients) were included. Seventeen different techniques were used to close GCF across all studies. The most popular were stents (n = 17), tissue sealants (n = 12) and over-the-scope clips (n = 11). Twenty-one studies used multiple techniques to attempt closure, including endoscopic vacuum therapy and revisional surgery. This systematic review demonstrates current practice focusing on endoscopic methods such as stents and over-the-scope clips, with relative success in closing GCF.

Pyelonephritic end-stage kidney and ureterocutaneous fistula in a Shetland pony.

A 12-y-old Shetland Pony was presented with a mucus-secreting fistula in the right paralumbar fossa. Surgery was performed to unravel the origin of the fistula. The horse died under anesthesia and was forwarded to autopsy. The right kidney was markedly atrophic and fibrotic, consistent with unilateral end-stage kidney. The right ureter was markedly thickened, but with luminal continuity leading into the urinary bladder where a partial obstruction caused by nodular para-ureteral fat necrosis was evident. The lumen of the cutaneous fistula was continuous with the right ureter; therefore, we diagnosed the lesion as a ureterocutaneous fistula. Anomalies of the ureter are uncommon, and ureterocutaneous fistula formation in equids has not been reported previously to our knowledge.

Pharyngeal Reconstruction Methods to Reduce the Risk of Pharyngocutaneous Fistula After Primary Total Laryngectomy: A Scoping Review.

INTRODUCTION: The most common early postoperative complication after total laryngectomy (TL) is pharyngocutaneous fistula (PCF). Rates of PCF are higher in patients who undergo salvage TL compared with primary TL. Published meta-analyses include heterogeneous studies making the conclusions difficult to interpret. The objectives of this scoping review were to explore the reconstructive techniques potentially available for primary TL and to clarify which could be the best technique for each clinical scenario. METHODS: A list of available reconstructive techniques for primary TL was built and the potential comparisons between techniques were identified. A PubMed literature search was performed from inception to August 2022. Only case-control, comparative cohort, or randomized controlled trial (RCT) studies were included. RESULTS: A meta-analysis of seven original studies showed a PCF risk difference (RD) of 14% (95% CI 8-20%) favoring stapler closure over manual suture. In a meta-analysis of 12 studies, we could not find statistically significant differences in PCF risk between primary vertical suture and T-shaped suture. Evidence for other pharyngeal closure alternatives is scarce. CONCLUSION: We could not identify differences in the rate of PCF between continuous and T-shape suture configuration. Stapler closure seems to be followed by a lower rate of PCF than manual suture in those patients that are good candidates for this technique.

Snodgrass Hypospadias Repair At Ayub Teaching Hospital: An Audit Of Complications And Outcomes.

BACKGROUND: There are many reported techniques for the repair of hypospadias, and new ones are being reported, which suggests that none is perfect. This study reports the anatomical success rate when using Snodgrass Technique. METHODS: In this descriptive case series, 296 patients who fulfilled the inclusion criteria, by being treated by Snodgrass urethroplasty, were enrolled. The study was conducted at the Department of Surgery, Unit-C, MTI, Ayub Teaching Hospital Abbottabad between May 2008 and June 2021. RESULTS: Mean age of the patients was 2.4±.8 years, 79.7% (n=236) had anterior (glanular, coronal, sub coronal) meatal location and 20.3 % (n=60) had middle urethral meatus (distal & mid-shaft). The mean operative time was 52 min. 5.1% of patients developed neo-meatal stenosis (n=15), 7.1% (n=21) patients develop a urethral cutaneous fistula (compared to 5% in larger centers, 16% from smaller centers), 11.8% (n=35) developed wound infection, 2% (n=6) had complete disruption. The cosmetic appearance of the penis was "excellent"/good (shape of meatus was slit-like and vertically oriented) in 60.1% (n=178) patients, "acceptable" in 30.1% (n=89), and "not acceptable" in 9.8% (n=29). CONCLUSIONS: Snodgrass technique has a low complication rate, offers an acceptable cosmetic outcome and can be successfully applied to a wide range of defects from distal to mid-shaft hypospadias. Common complications include urethral-cutaneous fistula and meatal stenosis; both occur in a low and acceptable number of patients.

Effect of possible risk factors for pharyngocutaneous fistula after total laryngectomy of laryngeal carcinomas and surgical wound infection: A meta-analysis.

A meta-analysis study to assess the effect of possible risk factors for pharyngocutaneous fistula (PCF) after total laryngectomy of laryngeal carcinoma. A comprehensive literature examination till January 2023 was implemented and 1794 linked studies were appraised. The picked studies contained 3140 subjects with total laryngectomy of laryngeal carcinomas in the picked studies' baseline, 760 of them were PCF, and 2380 were no PCF. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to calculate the consequence of possible risk factors for PCF after total laryngectomy of laryngeal carcinomas and surgical wound infection after total laryngectomy of laryngeal carcinoma by the dichotomous and continuous styles and a fixed or random model. The PCF had a significantly higher surgical wound infection (OR, 6.34; 95% CI, 1.89-21.27, P = .003) compared with the no PCF in total laryngectomy of laryngeal carcinomas. The smoking (OR, 1.73; 95% CI, 1.15-2.61, P = .008), and preoperative radiation (OR, 1.90; 95% CI, 1.37-2.65, P < .001) had significantly higher PCF as a risk factor in total laryngectomy of laryngeal carcinomas. The preoperative radiation had a significantly lower spontaneous PCF closure (OR, 0.33; 95% CI, 0.14-0.79, P = .01) compared with the no preoperative radiation in total laryngectomy of laryngeal carcinomas. However, the neck dissection (OR, 1.34; 95% CI, 0.75-2.38, P = .32), and alcohol intake (OR, 1.95; 95% CI, 0.76-5.05, P = .17), had no significant effect on PCF in total laryngectomy of the PCF had a significantly higher surgical wound infection, and preoperative radiation had a significantly lower spontaneous PCF closure in total laryngectomy of laryngeal carcinomas. Smoking and preoperative radiation were shown to be risk factors for PCF, however, neck dissection and alcohol intake were not shown to be risk factors for PCF in total laryngectomy of laryngeal carcinomas. Although precautions should be taken when commerce with the consequences because some of the picked studies for this meta-analysis was with low sample sizes.

Surgical treatment of tracheocutaneous fistula and tracheostomy scars using a hinged flap and local myocutaneous flap.

Tracheocutaneous fistula and tracheostomy scar are complications associated with the prolonged use of tracheostomy tubes. They have functional and cosmetic problems owing to tracheal tugging during swallowing and easily visible scars. Although many procedures exist to correct this issue, there is no consensus on the optimal surgical technique. Therefore, an ideal surgical procedure was devised. The study was performed on 12 patients between September 2016 and May 2021. All patients had persistent tracheocutaneous fistulas or hypertrophic scars on the neck after tracheostomy. All procedures were performed using a hinged flap and two myocutaneous local flaps. All patients had no complications, and their aesthetics were excellent in postoperative photographs. The scar was better on the straight scar when the flap's skin is denuded than on the VY advancement flap. It should be noted, however, that this procedure can cause the flap to become congested in a short period after head and neck surgery. This procedure is safe, reliable and simple for surgical closure. This was found to produce excellent cosmetic results with no major complications.

Outcomes and complications of simple layered closure of persistent tracheocutaneous fistula after tracheostomy in childhood.

BACKGROUND: Up to half of all children who have a tracheostomy will develop a persistent tracheo-cutaneous fistula (TCF) after decannulation. Surgical closure of the TCF is technically easy but post-operative complications can be immediate and life-threatening. These include air leak from the tracheal repair leading to massive surgical emphysema or pneumothorax. We reviewed our experience of TCF closure to try to identify potential risk factors for complications. METHOD: Retrospective case record review of all children (0-16 years) who underwent surgical TCF closure between January 2010 and December 2021 following development of a persistent TCF after decannulation of a tracheostomy. RESULTS: We identified 67 children. They ranged in age from 14 months to 16 years (median 3 years 10 months) at the time of the TCF closure. Major medical comorbidities were present in 90%. Pre-operative pulse oximetry with the fistula occluded was used in 29 children (43%). An underwater leak test was performed in 28 (42%). A non-suction drain was used in 29 children (43%). Prophylactic antibiotics were prescribed for 30 children (45%). Post-operative complications occurred in 15 children (22%). Life-threatening air leak occurred in the immediate post-operative period in 2 children (3%). Respiratory distress occurred in 3 children (4%) in the recovery area immediately after surgery. None required re-tracheostomy. Three children suffered post-operative pneumonia (4%), and wound infections occurred in 8 children (12%). We were unable to show a significant association between patient or surgical factors and complications. DISCUSSION: Complications for TCF closure are unfortunately common and it is unclear from the available evidence how best to prevent them. Further research is required.

Endoscopic Kehr's T-Tube Placement to Treat Persistent Large Gastro-cutaneous Fistula After One Anastomosis Gastric Bypass: Video Demonstration.

BACKGROUND: We aim to show the endoscopic placement of a T-tube to treat a persistent large gastro-cutaneous fistula after OAGB. METHODS: We present the case of a 46-year-old woman with BMI of 48 kg/m2, who underwent OAGB and was re-operated on the 2nd postoperative day (POD) for leakage. Washing and drainage of the abdominal cavity was performed, and no fistulous orifice was identified. An upper gastrointestinal (GI) endoscopy was performed at POD 20 for the persistence of leakage of 150 ml/day by the drain and a gastric fistulous orifice of 2 cm was detected. RESULTS: At POD 22, under general anesthesia, upper GI endoscopy was performed and a T-tube was placed in the fistulous orifice with a "rendez-vous" technique (as demonstrated in the Video), placing the T branch in the digestive lumen pressed against the wall and the long part of the T exiting at the cutaneous orifice. The T-tube was clamped after 3 days and the patient could be gradually re-fed. The patient was discharged 8 days after the procedure, with perfect clinical tolerance and no complications. The ablation of the tube one was performed on POD 84. No relapse occurred during a follow-up of 48 months. CONCLUSION: Persistent large gastro-cutaneous fistulas with an orifice bigger than 1 cm in diameter are difficult to manage. The endoscopic placement of a T-tube seems a useful option, which may facilitate the healing of the fistula. Further studies are needed to better define the role of this procedure.

Role of Exosomes in Pharyngucutaneous Fistula After Total Laryngectomy.

Pharyngocutaneous fistula is the most common complication after total laryngectomy and is difficult to heal. Although conservative treatment and surgical repair are effective, they often take longer and additional trips to the operating room, which undoubtedly increases the financial burden on patients. Especially in combination with diseases such as diabetes and hypertension, which affect the efficacy of surgery. Adding growth factors into the repair material can promote fibroblast proliferation, angiogenesis, and accelerate wound healing. A substantial number of studies have shown that a type of nanoscale extracellular vesicle, called exosomes, facilitates organization repair by promoting blood vessel production, protein polysaccharides, and collagen deposition, thereby representing a new type of cellular therapy. At present, there is little research on the application of exosomes in pharyngocutaneous fistula regeneration after total laryngectomy. In this review, we summarize the biological characteristics of exosomes and their application in biomedical science, and highlight their application prospects in pharyngocutaneous fistula regeneration after total laryngectomy.

Evaluation of preoperative cutaneous fistula as a risk factor for recurrence of thyroglossal duct cyst in children.

The aim of this study is to investigate the risk factors for recurrence after thyroglossal duct cyst (TGDC) surgery, differentiating between infections with and without a cutaneous fistula. This is a retrospective analysis of all paediatric TGDC in a tertiary care centre with at least 2 years of postoperative follow-up. One hundred and thirty-one patients met the inclusion criteria of the study. A multivariate analysis was performed to analyse the main risk factors for recurrence (presence of a fistula, infection, age). 116/131 patients were managed primarily in our institution; 15 patients had previously been operated on in another centre. The recurrence rate was 4.3% (5/116) when the patient was operated on in our institution at the first operation, and overall, recurrence of TGDC occurred in 20/131 (15.3%) patients. Age was not a risk factor for recurrence (p = 0.596). Two or more episodes of preoperative TGDC infection were a statistically significant risk factor in univariate analysis (p = 0.021) but not in multivariate analysis adjusted for age and the presence of a cutaneous fistula (p = 0.385). In multivariate analysis, cutaneous fistula formation was an independent risk factor for recurrence when adjusted for age and preoperative TGDC infection (Hazard ratio = 5.35; p = 0.011). CONCLUSIONS: A preoperative cutaneous fistula was a critical and independent risk factor for recurrence of operated TGDC, whereas age and TGDC infection were not identified as risk factors for recurrence after surgery. This information should be given to patients and parents before surgery. WHAT IS KNOWN: • The risk factors for recurrence after thyroglossal duct cyst surgery described in the literature are preoperative infection and young age, but this is not supported by strong evidence. • The role of cutaneous fistula formation is unclear. WHAT IS NEW: • The main risk factor for recurrence of TGDC is the presence of a preoperative cutaneous fistula, with an estimated hazard ratio of 4.95 (p = 0.016) in multivariate analysis. • The presence of two preoperative infections was also associated with a greater risk of recurrence in univariate analysis; age and gender were not associated with an increased risk of recurrence.

Laparoscopic management of Crohn's disease-related complex enterovesical, enterocutaneous and enteroenteric fistula: A case report.

The management of Crohn's disease is medical, with surgery reserved for emergencies and complications. Fistulizing Crohn's disease can present with either an internal or external fistula. Internal fistulae are common in patients with ileocolonic disease. Enterovesical fistulae form a very small part of these internal fistulae. An ileovesical fistula with other concomitant internal or external fistulae is a complex fistula. A patient with an ileovesical fistula further compounded by an enteroenteric fistula and an enterocutaneous fistula is a difficult surgical patient to manage because of the resultant dense inflammation. Here we report a case of complex ileovesical fistula (concomitant enterocutaneous fistula and enteroenteric fistula) managed by a laparoscopic approach.

Application of the Supraclavicular Artery Island Flap for Fistulas in Patients With Laryngopharyngeal Cancer With Prior Radiotherapy.

OBJECTIVE: To evaluate the effect of the supraclavicular artery island flap (SAIF) in reconstructing pharyngocutaneous fistula in patients with laryngopharyngeal cancer with prior radiotherapy. METHODS: Six patients with laryngopharyngeal cancer with pharyngocutaneous fistula due to previous radiotherapy and surgery during 2016 to 2019 were retrospectively analyzed. Initially, the fistula was treated conservatively. The SAIF was applied with double folding technique to reconstruct fistula in the patients who failed to heal after conservative treatment. RESULTS: The fistulae closed in 4 patients after conservative treatment. After SAIF operation, fistula closure was achieved in the other 2 patients who received highest dose of radiation and had largest fistulae size. The flaps grew well and there were no donor-site complications in these 2 patients. All patients achieved oral feeding without any complications. CONCLUSION: The SAIF is an effective and safe approach to reconstruct the pharyngocutaneous fistula after laryngopharyngeal surgery in patients with laryngopharyngeal cancer with previous radiotherapy, especially for those who have received high-dose radiation and have large fistula.

Perineal burn injury with hidradenitis suppurativa: A case report.

RATIONALE: Hidradenitis suppurativa (HS) is a chronic, inflammatory skin disease which usually presents with painful, deep-seated, inflamed lesions in the apocrine gland-bearing areas. Severe HS has interconnecting sinus tracts and when it occurs in the perianal region, perianal fistulas can form. Obesity and smoking are 2 risk factors for the development of HS. PATIENT CONCERNS: We report a case of a 33-year-old male diagnosed with perianal HS and perianal fistula following a burn injury to the area that occurred during childhood. DIAGNOSIS: Through integration of the clinical signs and imaging results, the patient was diagnosed with HS, Hurley stage III with perianal fistulas. INTERVENTIONS: The patient accepted surgical therapy. Performed under the general anesthesia, the procedure comprised sinus tracts excision and drainage. OUTCOMES: The patient was discharged from the hospital 6 weeks after surgery. LESSONS: The pathogenesis of the HS in this case was the burn injury interfering with sweat gland formation around the anus. Moreover, the scar from the burn made surgical treatment difficult.

Dermal tunnels influence time to clinical response and family history influences time to loss of clinical response in patients with hidradenitis suppurativa treated with adalimumab.

BACKGROUND: Clinical response in hidradenitis suppurativa (HS) is most commonly assessed using the Hidradenitis Suppurativa Clinical Response (HiSCR) measure. Dermal tunnels, increased body mass index, smoking and antibiotic use significantly decrease the odds of achieving HiSCR. However, there are few data exploring if clinical features are also associated with length of time to achieve clinical response and/or time to lose clinical response. AIM: To explore whether variables associated with achievement of HiSCR are associated with time to achieve HiSCR and time to loss of HiSCR in patients with HS treated with adalimumab 40 mg weekly in the PIONEER open-label extension study. METHODS: Time-to-event analyses were performed to estimate time to achieve HiSCR and time to loss of HiSCR. The log rank test was used to compare cumulative incidence curves for a priori patient- and disease-associated factors. Cox regression analysis was performed to compare time-to-event outcomes in the presence of a priori variables. All statistical analyses were completed with R software (V3.5.3). RESULTS: Presence of dermal tunnels significantly increased the time to achieve HiSCR (median 32.6 vs. 14.3 weeks, P = 0.02) and the hazard ratio (HR) was significant after controlling for patient and disease factors (HR = 0.70, 95% CI 0.51-0.96, P = 0.03). A positive family history of HS significantly decreased the time to loss of HiSCR (median 11.4 vs. 18 weeks, P < 0.001) and remained significant in Cox regression analysis (HR = 2.01, 95% CI 1.40-2.88, P < 0.001). CONCLUSION: The presence of dermal tunnels significantly influences the odds of achieving HiSCR and the time to achieve HiSCR, while family history influences time to loss of HiSCR.

Tension Pneumoventricle Secondary to Cutaneous-Ventricular Fistula: Case Report and Literature Review.

BACKGROUND: Tension pneumoventricle (TPV) is a subtype of tension pneumocephalus in which the air is trapped inside the ventricles through a one-way osteodural defect, causing an increase in intracranial pressure. TPV secondary to cutaneous-ventricular fistula has been reported only twice in the literature. CASE DESCRIPTION: Herein, we report the third case in a 53-year-old woman who developed TPV with decreased level of consciousness after removal of a posterior fossa meningioma while she was on external ventricular drainage. There was no identifiable bony defect on neuroimaging. The drain was changed urgently, and the fistula located at the drain tunneling site was sealed. CONCLUSIONS: This case report highlights the importance of suspecting and treating cutaneous-ventricular fistulas in TPV urgently in patients without skull base defects or those who showed no improvements with external ventricular drainage.

Lift and VAAFT for high trans-sphincteric anal fistula: a single center retrospective analysis.

PURPOSE: The management of complex anal fistulas remains a challenge, mainly due to the considerable risk of incontinence. We compared LIFT and VAAFT in the treatment of complex anal fistulas in terms of healing time, recurrence, continence, morbidity, and postoperative pain, focusing also on patients with local abscess at the time of surgery. METHODS: We include all patients with high trans-sphincteric anal fistula even with abscess at the time of surgery. Anorectal manometry, endoanal ultrasound, Cleveland Clinic fecal incontinence score, VAS score, and number of previous fistula treatment were recorded. The clinical examination defined healing, insufficiency or recurrence of the fistula. RESULTS: Fifty-four consecutive patients are undergoing surgery: 26 patients underwent LIFT and 28 underwent VAAFT. During the 18 months of follow-up there were no differences in terms of AM, CCFIS and VAS scores. Days of healing, failure, and recurrence rate were comparable in both groups. The subgroup of patients with local abscess undergoing LIFT showed worse results in terms of failure and recurrence rate (p < 0.05). CONCLUSIONS: Both techniques are safe and effective and can offer long-term benefits. LIFT should not be used as a first treatment in high trans-sphincteric fistula with perianal abscess.

Third or fourth branchial pouch sinus lesions: a case series and management algorithm.

BACKGROUND: The purpose of this study was to develop an effective management algorithm for lesions of third or fourth branchial sinuses. STUDY DESIGN: Case series with chart review. METHODS: Data from patients who were identified as having third or fourth branchial pouch sinus lesions in a single institution between January 2014 and December 2018 were retrospectively collected. RESULTS: All 67 patients underwent fistulectomy. First, we classified the patients into five types based on their anatomic features. Then, we considered four optimized surgical methods and adopted the appropriate method with full consideration of the patient's clinical characteristics. The great majority of cases occurred on the left side of the neck (68.7%) and most commonly presented as either a recurrent low-neck abscess or cutaneous discharging fistula with neck infection. Effective preoperative examination included administering contrast agent prior to a computed tomography (CT) scan and in-office laryngoscopy during the quiescent period of inflammation. Ultrasound was also very helpful in determining the presence of thyroiditis. The mean follow-up duration after excision of the lesion was 25.8 months. To date, only 1 (1.5%) recurrence and no obvious complications have been observed. CONCLUSION: Refining fistula subtypes and adopting corresponding treatment measures can reduce the recurrence rate and improve curative effects. We propose and advocate this treatment algorithm for all third and fourth branchial pouch lesions.

Delayed complication of tracheocutaneous fistula closure with severe compromising subcutaneous emphysema.

We report a significant complication after tracheocutaneous fistula (TCF) excision with closure by secondary intention in a 4-year-old boy who had been tracheostomy dependent since infancy. He had a persistent 3 mm TCF one year after decannulation. On postoperative day 2 the patient developed profound subcutaneous emphysema and pneumomediastinum. He was extubated after 2 days and discharged from the hospital on postoperative day 7. At follow up he had complete resolution of subcutaneous emphysema and complete closure of the TCF. The main methods of TCF closure and management of subcutaneous emphysema are discussed along with the lessons learned from this case.
