Redo partial aortic root remodelling in type A dissection with an aorto-left atrial fistula.

A 72-year-old male with a history of a triple-vessel coronary artery bypass graft years ago presented with a DeBakey type 2 aortic dissection and an aorto-left atrial fistula with patent bypass grafts (left internal mammary artery and saphenous vein grafts). He developed pulmonary oedema and required intubation. The right axillary artery was cannulated. After the ascending aorta and left internal mammary artery were clamped, the aorta was transected, leaving aortic tissue around two saphenous vein grafts as two separate patches. An entry tear was found adjacent to the proximal anastomosis of the saphenous vein graft to the posterior descending artery. A fistula, which was located between a false lumen in the non-coronary sinus and the dome of the left atrium, was primarily closed. Because the adventitia was thinned out in the non-coronary sinus due to aortic dissection, partial aortic root remodelling was performed with resuspension of the commissures. Hemiarch repair was performed under moderate hypothermia and unilateral antegrade cerebral perfusion. After systemic perfusion was resumed, the locations of the saphenous vein graft buttons were determined. The ascending graft was cross-clamped again; the saphenous vein graft to the obtuse marginal branch graft was reimplanted using the Carrel patch technique while a saphenous vein graft to the posterior descending artery required interposition of a 10-mm Dacron graft to accommodate the length.

Stereotactic ablative brachytherapy versus percutaneous microwave ablation as salvage treatments for lung oligometastasis from colorectal cancer.

BACKGROUND: The treatment for lung oligometastasis from colorectal cancer (CRC) remains challenging. This retrospective study aimed to compare the local tumor control, survival and procedure-related complications in CRC patients undergoing low-dose rate stereotactic ablative brachytherapy (L-SABT) versus percutaneous microwave ablation (MWA) for lung oligometastasis. METHODS: Patients between November 2017 and December 2020 were retrospectively analyzed. Local tumor progression-free survival (LTPFS) and overall survival (OS) were analyzed in the entire cohort as well as by stratified analysis based on the minimal ablation margin (MAM) around the tumor. RESULTS: The final analysis included 122 patients: 74 and 48 in the brachytherapy and MWA groups, respectively, with a median follow-up of 30.5 and 35.3 months. The 1- and 3-year LTPFS rate was 54.1% and 40.5% in the brachytherapy group versus 58.3% and 41.7% in the MWA group (P = 0.524 and 0.889, respectively). The 1- and 3-year OS rate was 75.7% and 48.6% versus 75.0% and 50.0% (P = 0.775 and 0.918, respectively). Neither LTPFS nor OS differed significantly between the patients with MAM of 5-10 mm versus > 10 mm. Pulmonary complication rate did not differ in the overall analysis, but was significantly higher in the MWA group in the subgroup analysis that only included patients with lesion within 10 mm from the key structures (P = 0.005). The increased complications was primarily bronchopleural fistula. CONCLUSIONS: Considering the caveats associated with radioisotope use in L-SABT, MWA is generally preferable. In patients with lesion within 10 mm from the key pulmonary structures, however, L-SABT could be considered as an alternative due to lower risk of bronchopleural fistula.

The use of superficial circumflex iliac perforator (SCIP) pedicle vein for lymphovenous anastomosis to treat inguinal lymphatic fistula: A case report.

The management of lymphatic fistulas following surgical procedures, in particular after inguinal lymphadenectomy, represents a significant clinical challenge. The current case report shows the novel use of the superficial circumflex iliac perforator (SCIP) pedicle vein for lymphovenous anastomosis (LVA) to treat a chronic inguinal lymphatic fistula in a 58-year-old male patient. This patient had developed a persistent lymphorrhea and wound dehiscence after a right inguinal lymph node biopsy performed for oncological reasons 1.5 months before. Pre-operative assessment with indocyanine green (ICG) lymphography confirmed a substantial lymphatic contribution to the wound discharge, thus guiding the surgical strategy. During the procedure, a pedicled tissue segment containing the SCIV was dissected and utilized to fill the wound's dead space and facilitate LVA with the leaking lymphatic vessel. Notably, a coupler device was employed for the anastomosis due to the large caliber of the lymphatic vessel involved, a technique not commonly reported in lymphatic surgeries. The result of the procedure was successful, with intra-operative ICG imaging confirming the patency of the anastomosis. After surgery the wound healed without complications. This case illustrates the potential of SCIV employment in lymphatic fistula repair in the inguinal region. While further research is needed to validate these findings, this report provides an unconventional approach to a relatively common problem in clinical practice.

Congenital midline upper lip sinus in an infant.

Congenital lip sinus is a rare entity with upper lip sinus being rarer than the lower lip sinus. It can be an isolated entity or associated with cleft lip, palate or Van der Woude syndrome. Syndromic association requires proper evaluation and aggressive surgical treatment. Preoperative delineation of the sinus tract with ultrasound sonography or MRI is mandatory. Simple excision is sufficient in cases of isolated sinuses. In this article, we report an infant with upper lip sinus managed successfully with simple excision and reviewed the literature.

Distal pancreatectomy.

NTRODUCTION: Distal pancreatectomy is a standard surgical procedure for selected benign, premalignant, and malignant lesions localized in the pancreatic body or tail. Surgical resection remains the only curative option for patients diagnosed with adenocarcinoma of the pancreas. PATIENTS AND METHODS: Perioperative and postoperative clinical courses were retrospectively assessed in patients, who underwent distal pancreatectomy during the 2011‒2021 period. RESULTS: During the 2011‒2021 period, a total of 112 distal pancreatectomies were performed. 67 patients (59.8%) underwent laparoscopic distal pancreatectomy, and 45 patients (40.2%) open laparotomy. The conversion was necessary for 13 patients (11.6%). Distal pancreatectomies performed laparoscopically were associated more often with biochemical leak and the development of grade B fistula, on the other hand grade C fistula developed only in patients operated by open laparotomy (LPT). The mean operating time was slightly longer in the laparoscopic group (227.1 min vs 214.6 min). The mean estimated blood loss was significantly higher in the LPT group (540.4 ml vs 191.9 ml). The mean hospitalization time was slightly longer in the LPT group (11.8 days vs 9.3 days). The rates of early reoperations were comparable between both groups (6 vs 5). CONCLUSION: Laparoscopic techniques are preferred in centers around the world to bring patients benefits by using a minimally invasive approach. These techniques are also preferred in our center, in nearly 60% of all distal pancreatectomies performed during 10 years, but on the other hand, there is a much more careful approach chosen in cases of malignant disease to achieve adequate radicality (Tab.4, Ref. 20).

Successful treatment of gastrosplenic fistula after sleeve gastrectomy.

INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) is one of the most performed bariatric procedures. But it is also associated with serious and potentially life-threatening staple line-related complications, such as stomach leak and bleeding. CASE REPORT: The article describes a case of surgical treatment of an early fistula between the stomach and the spleen 3 weeks after LSG. We have focused our attention on the diagnosis and possible treatment options for this potentially life-threatening complication. CONCLUSION: Efforts to reduce the frequency of leakage after LSG include a number of different measures. It is advisable to have expert knowledge not only in primary bariatric surgery, but also in the management of problems and reoperations in gastrointestinal surgery. An individualized approach and multidisciplinary teamwork are essential for successful therapy.

Ventriculo-gallbladder shunt: case series and literature review.

BACKGROUND: The ventriculoperitoneal shunt (VPS) is the gold-standard surgical technique to treat hypertensive hydrocephalus; however, it may fail in 20 to 70% of cases. The present study shows an alternative for patients with contraindications to VPS. METHODS: A case series of nine patients. The medical records of all patients under 17 years of age who underwent ventriculo-gallbladder (VGB) shunt at a pediatric hospital from January 2014 to October 2022 were reviewed. RESULTS: There were 6 (66.7%) males and 3 (33.3%) females. The average age of 73.6 months or 6.1 years at the time of surgery. They had undergone, on average, 5.1 VPS reviews before the VGB shunt. Five (55.5%) had complications of VGB shunt: infection (11.1%), atony (11.1%), hypodrainage (11.1%), and ventriculoenteric fistula (22.2%); all these patients got better at surgical reapproach, and in two of them, the VGB shunt was re-implanted. CONCLUSION: This case series shows a lower risk of death and a similar risk of complications compared to other alternative shunts. This article spotlighted VGB as a viable alternative when VPS fails or has contraindications.

Uterovesical fistula and its treatment in Sub-Saharan Africa.

AIM:  Aim of the study to summarize the current information on diagnostic and treatment options for uterovesical fistula as a consequence of iatrogenic complication. Methods: Literature review of available information on surgical treatment options for uterovesical fistula resulting from previous caesarean section and comparison with our own experience in the developing world. Conclusion: Uterovesical fistula is an abnormal communication between the bladder and uterus. The cause of this pathology in most cases is an iatrogenic complication, most commonly arising after a caesarean section. The incidence of this pathology varies significantly geographically. In developed countries, these fistulas are rather rare. On the other hand, in developing countries, uterovesical fistulas are more common with a significant impact on the subsequent life of the patient due to generally inaccessible health care.

Two-flap technique with interpositional dermofat graft for anterior oronasal fistula closure in patients with cleft: A case series.

BACKGROUND: Oronasal fistula at the anterior hard palate is one of the common sequelae after cleft surgery, and the leakage negatively affects the patient's quality of life. Although several surgical techniques have been proposed for reconstruction, it remains challenging because of the scarred regional tissue with a high rate of fistula recurrence. In this study, we present the anterior oronasal fistula repair using a two-flap technique with an interpositional dermofat graft (DFG). METHODS: A retrospective review of anterior oronasal fistula repair performed by the senior author between April 2018 and August 2022 at the Craniofacial Center was conducted. Patients who underwent a fistula repair using the technique were further identified and investigated. RESULTS: Thirty-four operations were performed using the technique, and 31 fistulas were completely closed, with a success rate of 91.2%. The fistula symptom improved but persisted postoperatively in 3 patients, of whom 2 patients underwent a second fistula repair using the same procedure, resulting in successful closure. Fistula recurrence was significantly correlated with fistula size (p = 0.04). The DFG was simultaneously utilized for nasal dorsum and/or vermillion reconstruction in 28 cases. CONCLUSION: The two-flap technique enabled tension-free approximation, and the interpositional DFG facilitated watertight closure of the fistula, resulting in a high success rate of anterior oronasal fistula repair. The fistula closure could be combined with other revisional procedures for cleft-related deformities, where the DFG was simultaneously utilized.

Long-term outcomes of the pentaspline pulsed-field ablation catheter for the treatment of paroxysmal atrial fibrillation: results of the prospective, multicentre FARA-Freedom Study.

AIMS: Pulmonary vein isolation (PVI) is a well-established strategy for the treatment of paroxysmal atrial fibrillation (PAF). Despite randomized controlled trials and real-world data showing the promise of pulsed-field ablation (PFA) for this treatment, long-term efficacy and safety data demonstrating single-procedure outcomes off antiarrhythmic drugs remain limited. The aim of the FARA-Freedom Study was to evaluate the long-term efficacy and safety of PFA using the pentaspline catheter for PAF. METHODS AND RESULTS: FARA-Freedom, a prospective, non-randomized, multicentre study, enrolled patients with PAF undergoing de novo PVI with PFA, who were followed for 12 months with weekly transtelephonic monitoring and a 72-h Holter ECG at 6 and 12 months. The primary safety endpoint was a composite of device- or procedure-related serious adverse events out to 7 days post-ablation and PV stenosis or atrioesophageal (AE) fistula out to 12 months. Treatment success is a composite of acute PVI and chronic success, which includes freedom from any documented atrial tachyarrhythmia longer than 30 s, use of antiarrhythmic drugs or cardioversion after a 3-month blanking period, or use of amiodarone or repeat ablation at any time. The study enrolled 179 PAF patients (62 ± 10 years, 39% female) at 13 centres. At the index procedure, all PVs were successfully isolated with the pentaspline PFA catheter. Procedure and left atrial dwell times, with a 20-min waiting period, were 71.9 ± 17.6 and 41.0 ± 13.3 min, respectively. Fluoroscopy time was 11.5 ± 7.4 min. Notably, monitoring compliance was high, with 88.4 and 90.3% with weekly events and 72-h Holter monitors, respectively. Freedom from the composite primary effectiveness endpoint was 66.6%, and 41 patients had atrial tachyarrhythmia recurrence, mostly recurrent atrial fibrillation (31 patients). The composite safety endpoint occurred in two patients (1.1%), one tamponade and one transient ischaemic attack. There was no coronary spasm, PV stenosis, or AE fistula. There were four cases of transient phrenic nerve palsy, but all resolved during the index procedure. CONCLUSION: In this prospective, non-randomized, multicentre study, PVI using a pentaspline PFA catheter was effective in treating PAF patients despite rigourous endpoint definitions and high monitoring compliance and demonstrated favourable safety.

[Study on the management of granulation during surgery for congenital preauricular fistula infection stage].

Objective:To investigate the management of granulation tissue during surgery for infected congenital preauricular fistula and to assess the surgical outcomes. Methods:To summarize the surgical methods and the treatment of granulation methods in 140 cases of congenital preauricular fistula during the period of infection treated in our department from January 2018 to September 2022. The study divided patients into an observation group （79 patients） undergoing fistulectomy without granulation treatment, and a control group （61 patients） where fistulectomy and granulation resection were performed concurrently.. After six months of follow-up, the wound healing, recurrence rates, and the aesthetic assessment of granulation healing were evaluated using the Stony Brook Scar Evaluation Scale（SBSES）. Results:The two surgical approaches were applied to a total of 140 patients with infected congenital preauricular fistula. There was no statistical difference in wound healing and recurrence rates between the observation group and the control group. However, the observation group exhibited smaller scars. Conclusion:In cases of infected congenital preauricular fistula, surgical removal without excising granulation tissue is feasible, leading to effective healing and lesser scar formation.

Treating a Bypass with Bypass Surgery: Repair of a Duodeno-sigmoid Fistula Complicating Acute Diverticulitis.

Diverticular disease is common in Western countries; one-third of patients with diverticular disease develop diverticulitis during their lifetime of whom 5% may experience serious complications. We describe a rare complication of diverticulitis: a duodeno-colic fistula in a patient with an elongated sigmoid colon (dolicosigma). The patient complained of abdominal pain, diarrhea, weight loss, and feculent vomiting. Radiological studies and gastroscopy demonstrated a fistula between the second portion of the duodenum and the sigmoid colon. Curative surgery cured the fistula and completely resolved its associated signs and symptoms.

Successful Percutaneous Closure of an Aorto-right Ventricular Fistula After Sutureless Aortic Valve Replacement: A Case Report.

Rupture of a sinus of valsalva aneurysm (SVA) and the development of an aorto-right ventricular fistula (ARVF) is a rare condition, associated with high morbidity and mortality rates if left untreated. Opening of the SVA rupture into the right heart chambers may result in various morbidities, such as pulmonary hypertension. We present a case of a patient who developed ARVF following sutureless aortic valve replacement, and was subsequently treated successfully via a percutaneous approach.

Aesthetic Considerations of Simultaneous Reconstruction With Free Flap for Local Advanced Hypopharyngeal Combined With Cervical Esophageal Cancer.

BACKGROUND AND OBJECTIVE: Patients with local advanced hypopharyngeal combined with esophageal cancer often require total laryngectomy and cervical esophagectomy, which result in big-sized upper aerodigestive tract defects and neck deformities. Although free flap is widely used to reconstruct aerodigestive defects, the aesthetic results especially that of neck contour have not brought to the forefront or discussed extensively. This article aims to report the preliminary aesthetic results of free flap reconstruction for local advanced hypopharyngeal cancer combined with cervical esophageal cancer defects, highlighting the thickness of subcutaneous fat of the flap. METHODS: A retrospective study of 21 patients with local advanced hypopharyngeal combined with cervical esophageal cancer from July 2010 to August 2022 was conducted. After completing total laryngectomy, bilateral neck dissection, and removal of the tumor with safe margin, a free thigh flap of subcutaneous fat greater than 1 cm in thickness was used to reconstruct the hypopharyngeal and cervical esophageal defects. In addition to general demographic, oncological, and reconstructive data, preoperative and postoperative neck circumferences were recorded and compared. A subjective questionnaire survey was conducted on patients' satisfaction with postoperative neck contour. The patients were followed up from 3 to 10 years, with an average of 3 years. RESULTS: There were 2 cases (2/21) of free flap loss because of flap necrosis and secondary repair with a pedicled pectoralis major flap. Nineteen flaps (19/21) survived. Three cases (3/21) developed a pharyngeal fistula and one case (1/21) experienced salivary fistula, all of the fistulae healed after drainage and dressing change. There was a relatively high satisfaction rate among patients (16/21) with the postoperative neck contour. A paired sample t test showed no statistically significant difference between the preoperative and postoperative values ( t = 2.002, P > 0.05). Patients with a thicker subcutaneous fat flap (≥1.5 cm) had a more symmetrical and fuller neck contour during long-term postoperative follow-up. CONCLUSIONS: The application of a fat-rich subcutaneous free thigh flap to reconstruct the defect of local advanced hypopharyngeal combined with cervical esophageal cancer can achieve better neck aesthetic contour.
