Closure of a tracheocutaneous fistula by two hinged turnover skin flaps and a muscle flap: A case report

INTRODUCTIONTracheocutaneous fistula is a complication of tracheostomy. Tracheocutaneous fistulectomy followed by primary closure carries a high possibility of complications.PRESENTATION OF CASEAn 11-year-old boy underwent surgery to repair a tracheocutaneous fistula, using skin and muscle flaps. A vertical incision was made around the fistula and 3 skin flaps were prepared: 2 hinge flaps, and 1 to cover the skin defect (advanced flap). The 2 hinged turnover flaps were invaginated by multiple layered sutures, and a strap muscle flap was placed over the resulting tracheal closure. An advanced skin flap was used to cover the area of the previous defect. The patient was extubated immediately after surgery. He was discharged on the sixth postoperative day without tracheal leakage or subcutaneous emphysema. The patient is currently doing well, with no respiratory symptoms and no recurrence at the postoperative 5 months.DISCUSSIONOur technique is minimally invasive and has a low risk of lumen stenosis, other complications, or recurrence.CONCLUSIONThis technique demonstrates the multiple-layered closure of a tracheocutaneous fistula, using skin flaps and a muscle flap.     

Surgical treatment of recurrent tracheo-esophageal fistula using a latissimus dorsi pedicled muscle flap —Report of a case—

We report herein, a case of a child in whom a prepared latissimus dorsi muscle flap was successfully utilized in the treatment of recurrent tracheo-esophageal fistula (TEF). A 12-month-old girl who had undergone a primary repair of Gross’s type C esophageal atresia at 6 days of age and a secondary repair of recurrent TEF at 4 months of age experienced, postoperatively, repeated episodes of aspiration pneumonia caused by recurrence of the fistula. Thus, we performed a reoperation in which the fistula was excised, and a latissimus dorsi muscle pedicled flap was interposed between the tracheal and esophageal suture lines. Viability of the muscle flap was adequately achieved by means of a three-stage delayed operation. Although a minor anastomotic leakage of the esophagus was found postoperatively, it healed spontaneously, and the patient was commenced on a normal diet orally without any problems at 26 months of age.     

Thoracoscopic treatment of a broncho-esophageal fistula: A case report

IntroductionBroncho-esophageal fistula is a rare clinical condition which can be manifested with non-specific signs and symptoms.Presentation of a caseHere, we report an adult case of a broncho-esophageal fistula in a 43-year-old man referred for chronic cough after fluid food intake and weight loss. Barium swallow, esophagogastroduodenoscopy, bronchoscopy and Computed Tomography of the chest demonstrated a broncho-esophageal fistula between the apical segmental bronchus of the lower right lobe and the middle section of the esophagus. The patient underwent video-assisted thoracoscopic surgery for resection of the fistula. No post-operative complications occurred.DiscussionBroncho-esophageal fistula in adults is rare and its diagnosis is often delayed due to the frequent lack of specific symptoms. Although there is no standard protocol, the most widely used treatment is thoracotomy with identification and dissection of the fistula tract followed by repair of bronchial and esophageal defects.ConclusionsVideo-assisted thoracoscopic surgery appears to be an effective and minimally invasive approach for the treatment of broncho-esophageal fistulas, especially in young, healthy subjects.     

Plastic surgical treatment of a chronic thoracic duct fistula using a sternocleidomastoid muscle flap — a case report

Thoracic duct fistula is a rare but potentially serious complication of head and neck surgery. Such fistulae may be difficult to treat, and several techniques, both operative and non-operative, have been advocated. A case of successful surgical treatment of a chronic thoracic duct fistula is presented. The fistula occurred in a 51-year-old female following treatment of a solitary supraclavicular breast metastasis by local excision and radiotherapy. The divided duct was ligated and the area was covered with the clavicular head of the sternocleidomastoid muscle.     

Aorto-oesophageal fistula after corrosive ingestion: A case report

BACKGROUNDAorto-oesophageal fistula (AOF) are uncommon and exceedingly rare after corrosive ingestion. The authors report a case of AOF after corrosive ingestion that survived. A comprehensive literature review was performed to identify all cases of AOF after corrosive ingestion to determine the incidence of this condition, how it is best managed and what the outcomes are. CASE SUMMARYA previously healthy 30-year-old male, presented with a corrosive oesophageal injury after drain cleaner ingestion. He did not require acute surgical resection, but developed long-segment oesophageal stricturing, which was initially managed with cautious dilatation and later stenting. An AOF was suspected at endoscopy performed two months after the ingestion, when the patient represented with massive upper gastrointestinal bleeding. The fistula was confirmed on computerised tomographic angiography. The initial bleeding at endoscopy was temporised by oesophageal stenting; a second stent was placed when bleeding recurred later the same day. The stenting successfully achieved temporary bleeding control, but resulted in sudden respiratory distress, which was found to be due to left main bronchus compression caused by the overlapping oesophageal stents. Definitive bleeding control was achieved by endovascular aortic stent-grafting. A retrosternal gastroplasty was subsequently performed to achieve gastrointestinal diversion to reduce the risk of stent-graft sepsis. He was subsequently successfully discharged and remains well one year post injury.CONCLUSIONAOF after corrosive ingestion is exceedingly rare, with a very high mortality. Most occur weeks to months after the initial corrosive ingestion. Conservative management is ill-advised.     

Perianal squamous cell carcinoma: A case report

Introduction and importancePerianal carcinomas, though rare, are usually squamous cell carcinoma. Current literature recommends surgical excision for tumors staged T1-T2, N0 without external anal sphincter involvement, however our case demonstrated that tumors with superficial involvement of external sphincter fibers can be resected completely.Case presentationA 45-year-old Caucasian male presented with a perianal mass found to be squamous cell carcinoma. Initial imaging suggested the anal sphincter was spared, however intraoperatively tumor cells were found involving superficial external sphincter fibers and a portion was excised to ensure complete removal.Clinical discussionPerianal squamous malignancies are often misdiagnosed as more benign conditions. Treatment aims to preserve sphincter function and depends on tumor stage along with anatomical involvement.ConclusionDespite superficial muscle infiltration, the T2N0 perianal lesion was curable with surgical resection alone without recurrence or functional deficits reported one year later. This suggests surgical management may be possible in some cases with sphincter involvement.     

Surgical stabilization of severe flail chest with Judet and Sanchez-Lloret plates. A case report

IntroductionFlail chest is now usually treated by conservative methods and surgical fixation remains indicated in selected cases. Different techniques can be used for fixation. The aim of this paper is to present a case in which Judet and Sanchez-Loret plates were employed and to discuss the usefulness of this traditional technique.Presentation of caseA 79-year-old woman was admitted for left thoracic trauma with severe antero-lateral flail chest. She was affected by COPD with chronic respiratory failure, ischemic heart disease, autoimmune thrombocytopenia treated on chronic steroid therapy and severe osteoporosis. CT-scan detected multiple rib fractures, left hemothorax and lung contusions. An initial conservative treatment of flail chest involved compressive bandage and then internal pneumatic stabilization in ICU, but it failed. The patient underwent successful surgical treatment of the flail chest by fixation of the anterior fractures from the second to the eight rib. Judet and Sanchez-Lloret plates were used. A bilateral pneumonia developed during the rehabilitation period and the patient died two months after operation.DiscussionJudet and Sanchez-Lloret plates represent a traditional technique for fixation of flail chest. This technique is less and less used and progressively replaced by newer materials, especially titanium plates with screws or intramedullary struts. Our patient had multiple comorbidities and a very fragile bones that advised against use of screws or intramedullary struts.ConclusionJudet and Sanchez-Lloret plates can be still considered a useful tool for the fixation of flail chest in cases of thin and fragile bones.     

Surgical treatment of locally advanced papillary thyroid carcinoma after response to lenvatinib: A case report

IntroductionDifferentiated thyroid carcinomas (DTC) have good prognoses after complete resection. Nevertheless, when DTC is associated with an aerodigestive invasion, curative surgery is difficult to perform. However, there is no established neoadjuvant therapy for advanced DTC.Presentation of caseA 73-year-old man with thyroid papillary carcinoma was referred to our hospital. A computed tomography examination revealed a tumor in the upper right lobe of the thyroid, and multiple bilateral enlarged lymph nodes in the neck, involving the surrounding structures. The enlarged lymph node at the right upper neck was suspected to have invaded the right internal jugular vein, and the left paratracheal lymph node was suspected to have invaded the cervical esophagus and trachea. The tumor was considered resectable; however, surgery would have been highly invasive. Therefore, we initiated neoadjuvant therapy with lenvatinib. After administration of lenvatinib, the tumor decreased in size by 84.3% and the cervical lymph nodes by 56.0%. The patient underwent a total thyroidectomy, modified neck dissection, a resection of the muscular layer of the esophagus, and a tracheal sleeve resection and reconstruction.DiscussionThe SELECT trial demonstrated that lenvatinib had high response rate with short response time, in patients with radioiodine-refractory DTC. The results suggested that lenvatinib could be effective as neoadjuvant therapy.ConclusionFor an advanced DTC that requires removal through invasive surgery, preoperative lenvatinib treatment might be one of the options for a less invasive surgery.     

Phalangectomy combination double-pedicled digital artery flap for second-toe macrodactyly reconstruction: A case report

IntroductionPedal macrodactyly is a rare form of congenital deformity in which the toes and underlying structures are enlarged. The goal of most macrodactyly reconstruction surgeries is to reconstruct the affected toes to resemble the normal size such that the patient is able to wear shoes of the same size.Case presentationWe report a three-year-old female patient presenting with an enlargement of the right foot index and middle toes. The anomaly was noticed at two months of age and grew progressively. X-ray imaging revealed enlarged bones and soft-tissue hypertrophy proximal to the distal phalanx of the second and third digits. There was no history of other systemic or syndromic diseases. The patient underwent phalangectomy surgery involving reduction of the fibrofatty tissue, double-pedicle medial and lateral digital artery flap. Satisfactory results were noted at evaluation two months of after surgery.ConclusionMacrodactyly reduction surgeries are generally composed of several kinds of surgical techniques to provide the best results. The management of macrodactyly depends on the surgeon’s experience while considering the most suitable surgical technique to be performed in each case. Therefore, it was deemed necessary to report this case and its surgical technique. We hope that this case report will enrich the existing literature and be useful for the management of macrodactyly cases.     

Cecocutaneous fistula diagnosed by computed tomography fistulography: A case report

BACKGROUNDEnterocutaneous fistula (ECF) is an abnormal communication between the skin and the gastrointestinal tract and is associated with considerable morbidity and mortality. To diagnose ECF, X-ray fistulography and abdominal computed tomography (CT) with intravenous or oral contrast are generally used. If the anatomic details obtained from CT are insufficient, CT fistulography may help diagnose and determine the extent of the abnormal channel. However, CT fistulography is seldom performed in patients with insufficient evidence of a fistula.CASE SUMMARYA 35-year-old man with a prior appendectomy presented with purulence over the abdominal wall without gastrointestinal tract symptoms or a visible opening on the abdominal surface. His history and physical examination were negative for nausea, diarrhea, muscle guarding, and bloating. Local abdominal tenderness and redness over a purulent area were noted, which led to the initial diagnosis of cellulitis. He was admitted to our hospital with a diagnosis of cellulitis. We performed a minimal incision on the carbuncle to collect the pus. The bacterial culture of the exudate resulted positive for Enterococcus sp. ECF was thus suspected, and we arranged a CT scan for further investigation. CT images before intravenous contrast administration showed that the colon was in close contact with the abdominal wall. Therefore, we conducted CT fistulography by injecting contrast dye into the carbuncle during the CT scan. The images showed an accumulation of the contrast agent within the subcutaneous tissues, suggesting the formation of an abscess. The contrast dye tracked down through the muscles and peritoneum into the colon, delineating a channel connecting the subcutaneous abscess with the colon. This evidence confirmed cecocutaneous fistula and avoided misdiagnosing ECF without gastrointestinal tract symptoms as cellulitis. The patient underwent laparoscopic right hemicolectomy with re-anastomosis of the ileum and transverse colon.CONCLUSIONCT fistulography can rule out ECF in cases presenting as cellulitis if examinations are suggestive.     

Cutaneous metastasis from esophageal basaloid squamous cell carcinoma: A case report

Introduction and importanceBasaloid squamous cell carcinoma (BSCC) of the esophagus is a relatively rare histologic variant of squamous cell carcinoma. Here, we reported a case of solitary cutaneous metastasis as the first symptom of esophageal BSCC and was successfully treated with multidisciplinary treatment.Case presentationA 67-year-old man visited a local hospital with symptoms of dysphagia and cutaneous nodules on his left shoulder. Fluorine-18 fluorodeoxyglucose positron emission tomography revealed hypermetabolic accumulations in the middle thoracic esophagus, right recurrent laryngeal nerve lymph node, and epidermis of the left shoulder. Esophagogastroscopy revealed an ulcerative and infiltrating type tumor in the middle thoracic esophagus. Based on histopathologic examination of the endoscopic biopsy and the resected cutaneous tumor, the patient was diagnosed as esophageal BSCC with cutaneous metastasis. The patient was treated with chemotherapy followed by chemoradiotherapy. The therapeutic effect was a complete response, which was sustained for 39 months.Clinical discussionReview of previous literature in the PubMed database revealed only been two case reports on cutaneous metastasis of BSCC. Advanced BSCC of the esophagus with distant metastasis has a poor prognosis. Therefore, in our case, future careful follow-up is required.ConclusionEsophageal BSCC with cutaneous metastasis can be successfully managed by multidisciplinary treatment, including local resection of the cutaneous metastasis, systemic chemotherapy, and chemoradiotherapy.     

Free disease long-term survival in primary thoracic spine leiomyosarcoma after total en bloc spondylectomy: A case report

IntroductionTo describe an unusual primary vertebral leiomyosarcoma in thoracic spine.Presentation of caseAn isolated lesion of the T11 vertebra in a 62-year-old woman with no neurologic deficit is reported. Imaging findings indicated a nonspecific high-grade malignant lesion. TC-guided biopsy failed thus open incisional biopsy was needed. A diagnosis of low-intermediate mesenchymal sarcoma was made. A total en bloc spondylectomy of T11 was performed with three-column reconstruction. The histology and immunostaining showed the appearance of leiomyosarcoma. After diagnosis, post-operative radiation therapy was performed. Metastatic lesion was ruled out by CT scans of the chest, abdomen and pelvis, in addition to total body radionuclide scanning and 18-F-FDG-PET. After five years of follow-up, no signs of local recurrence, metastasis or distant lesions suggesting a primary lesion were observed.DiscussionVertebral primary leiomyosarcoma is exceedingly rare. Primary vertebral leiomyosarcoma diagnosis must be performed when the metastatic origin is excluded. For the treatment of primary tumors, total en bloc spondylectomy (TES) is the technique of choice to achieve marginal or wide tumor resection, decrease the risk of local recurrence and remote lesions and increase survival.ConclusionsA well-planned pre-operative study and a wide surgical excision can result in local tumor control and long-term survival. This case presents the longest disease-free survival period of a primary leiomyosarcoma in spinal location after total en bloc spondylectomy.     

Colouterine fistula: A case report of a rare complication of diverticular disease managed during the pandemic

Introduction and importanceColouterine fistulas related to diverticulitis are very rare due to the thickness of the uterine myometrium. Other causes related to colouterine fistula formation particularly malignancy, have to be considered. Diagnosis by imaging or endoscopy may be inconclusive.Case presentationWe are presenting a case of a 70-year-old female who presented with malodorous vaginal discharge and painful labial lesions. No previous history of surgery, gynecologic malignancy or other possible causes of the fistula was elicited. CT scan imaging suggested a colouterine fistula. The patient was admitted and underwent Exploratory laparotomy, Hartmann’s procedure and total hysterectomy with bilateral salpingo oophorectomy. The patient was discharged without perioperative complications.Clinical discussionColouterine fistulas are extremely rare complications of diverticular disease. Diagnosis entails clinical astuteness and judicious use of imaging and endoscopic modalities. Accurate diagnosis is essential to select the appropriate surgical approach, along with intraoperative findings patient status and prevailing conditions.ConclusionThis case is being presented not only for the rarity of the case but also for the complexity of the management and decision making during the period of the pandemic.     

Acute paraplegia in patient with spinal dural arteriovenous fistula after lumbar puncture and steroid administration: A case report

Introduction and importanceSpinal dural arteriovenous fistula (SDAVF) is an uncommon cause of longitudinal extensive transverse myelitis (LETM). It usually presents with vague congestive myelopathy symptoms and diagnosis is usually difficult on initial presentation. Common daily neurological interventions can aggravate the underlying pathophysiology leading to undesirable acute neurological deterioration. Intravenous steroids administration and lumbar (LP) puncture as a diagnostic tool are amongst the most commonly reported aggravating interventions. This rare case presentation highlights this association with its negative impact on the patient outcome in misdiagnosed cases.Case presentationThe authors present a sixty-eight-year-old male with paraplegia following steroid administration and LP for presumed inflammatory/autoimmune LETM in the setting of misdiagnosed SDAVF. The absence of flow voids on the conventional T2-weighted magnetic resonance image (MRI) lead to misdiagnosis. He had satisfactory neurological recovery few hours after surgical disconnection.Clinical discussionSDAVF is known to cause congestive myelopathy symptoms. Spinal angiogram is the gold standard for diagnosis. Although the exact mechanism is not fully understood, misdiagnosed cases like our case can develop severe neurological deterioration with steroid administration and lumbar puncture.ConclusionAlthough SDAVF is an uncommon cause of LETM, Clinicians should carefully exclude it before proceeding to steroid administration or performing LP as they can lead to devastating neurological deterioration.     

Delayed diagnosis of single compartment muscle contusion after radical hysterectomy in the lithotomy position: A case report

IntroductionMuscle contusions usually occur as a result of blunt trauma, which damages the muscle fibers and connective tissue without breaking the skin. Rapid bleeding can cause an increase in pressure that requires surgical intervention, commonly referred to as compartment syndrome. Here, we report a case with delayed diagnosis of single compartment muscle contusion in which compartment syndrome did not develop.Presentation of caseA 50-year-old woman underwent radical hysterectomy. She complained of edema and tenderness in the lower left leg on postoperative day 6. The serum creatine phosphokinase level was slightly elevated at 177 IU/L (normal range: 6–142 IU/L). T2-weighted magnetic resonance imaging revealed swelling of the muscle in the deep posterior compartment of the lower left leg, edematous fascia, and subcutaneous adipose tissue. She recovered naturally without other complications.DiscussionIn the lithotomy position during surgery, muscle contusion might occur, without general symptoms.ConclusionMagnetic resonance imaging is useful for diagnosis. For patients who complain of edema and tenderness in the lower leg after surgery in the lithotomy position, muscle contusions should be considered.     

Successful percutaneous transgastric diversion of a chronic post-operative combined pancreaticocutaneous and gastrocutaneous fistula using a snare-target technique: A case report

IntroductionGastrocutaneous fistula complicating a post-operative or post-pancreatitis pancreatic fistula is uncommon, but has a high mortality rate and typically occurs 6–9 weeks after initial drainage. Conventional methods of treatment may be limited by the size of the fistula tract and visibility.Presentation of caseA 57-year-old man presented with a pancreatic duct leak, ten days after undergoing a distal pancreatectomy for renal cell carcinoma metastasis. Initial drainage attempts resulted in a chronic pancreaticocutaneous fistula (PCF)¹ complicated by a separate gastric fistula sharing the same cutaneous tract along the inserted drain as well as recurrent symptomatic pleural effusions requiring repeat hospitalizations for management. The chronic fistula tract was too small for conventional direct puncture under fluoroscopic or endoscopic ultrasound guidance; therefore, percutaneous transgastric diversion of the combined pancreatico-gastrocutaneous fistula using a snare-target approach was performed with complete resolution of clinical symptoms.DiscussionComplicated pancreatico-gastrocutaneous fistulae are rare and typically require drainage, either surgically or via percutaneous direct transgastric puncture or endoscopic-ultrasound guided stent insertion. This case report demonstrates that a minimally-invasive percutaneous snare-target approach can be effective in treating complex fistulae too small to be accessed through these conventional methods. This case also demonstrates that transgastric drainage along the tract, remote from either organ’s fistula origin, can successfully divert and resolve the complex fistula without requiring direct drainage of the pancreatic duct itself.ConclusionIncorporating the snare-target technique facilitates accurate transgastric drain placement within chronic fistula, particularly when the fistula caliber is too small for conventional drainage methods.
