The contralateral based Cervico-pectoral rotation flap for large neck defects

Purpose We here describe our technique of contralateral based cervico-pectoral (CCP) flap for the reconstruction of large neck defect following resection of primary tumour or recurrence particularly due to the lymph node mass. Methods The study included the patients who underwent major head and neck surgical ablative procedures followed by CCP flap reconstruction between July 2020 and November 2020. Patients were kept on rigorous regular follow-up to evaluate for flap related complications like flap necrosis, flap dehiscence and oro-cutaneous fistula. Among the 5 patients included and presented in the series, 2 patients were salvage cases post adjuvant treatment. Results Five patients who have undergone head and neck reconstruction using CCP flap were included. No major flap related complications occurred in post-operative period. Conclusion The CCP flap is simple to perform and reproducible and can be added to the armamentarium for the reconstruction of large upper neck defect following resection of primary tumour or recurrence involving the cervical skin in resource limited setting and in contraindication for microvascular reconstruction. Proper planning, meticulous dissection and adequate release or rotation and tension free closure would provide best outcomes.

Video-assisted thoracoscopic parenchymal sparing “rotational” bronchoplasty for managing bronchial carcinoid tumor

We present a modified bronchoplasty technique involving rotation of the bronchial structures. Our goal was to reconstruct the bronchus without using any foreign material while fully preserving the parenchyma. We used a biportal VATS approach. The centrally located bronchial tumor at the juncture between the right main bronchus, the right upper lobe bronchus, and the bronchus intermedius was first resected. The right upper lobe bronchus was rotated caudally, toward the bronchus intermedius, together with a slight clockwise rotation posteriorly to facilitate the approximation and tension-free closure of the bronchial defect. This video tutorial demonstrates the operative steps and explains how the rotational aspect is achieved.

OV11 GIANT SPIEGEL HERNIA: 3D PLANNING AND MINIMALLY INVASIVE TREATMENT

Aim Demonstrate the advantages of 3D technology planning in complex cases of hernia surgery and technical tricks for giant Spiegel hernia repair. Material and Methods 71 year old patient, BMI 38, asthma, hypertensive; long history of symptomatic left flank mass. Giant Spiegel hernia was diagnosed, with significant omentum and colon migration to hernial cavity. It was decided to perform minimally invasive surgery. 3D model of the abdominal scan was performed, assessing hernia size, volume and its relationship with the abdominal cavity. We were able to rule out the possibility of compartment syndrome, and foresee that we could probably close the defect. Results preperitoneal transabdominal repair (TAPP) is performed, beginning with herniated content reduction, a delicate step where injuries should be avoided, with careful traction of the colon and omentum. Hernial defect is assessed, coinciding with the 3D model, the peritoneum sac is reduced, taking as much as possible to facilitate its posterior closure. The entire peritoneum of the Spiegel and inguinal region are dissected en bloc. Defect tension-free closure is performed with 2 continuous V-LOOK 2.0, subsequent placement of 15x15cm polypropylene mesh and posterior peritoneum closure. The patient is discharged the same day without incidents. Conclusions The 3D model allows us to assess the actual abdominal and hernia volume to simulate surgery findings. Its benefits are yet to be developed. Laparoscopic preperitoneal repair is an excellent approach for Spiegel's hernia. Complex cases are also candidates for outpatient surgery.

P028 COMBINING SEVEN ITEMS OF THE TOOLBOX TO TREAT A LARGE INCISIONAL HERNIA WITH HETEROTOPIC OSSIFICATION: A CASE REPORT

Aim We present our approach of treating a W3 (EHS-Classification) incisional hernia with heterotopic ossification in the abdominal wall. Material and Methods a 62-years-old female patient presented with a hernia in her inverted-T incision (midline and transverse) after undergoing multiple laparotomies. The CT-scan showed calcified structures within the abdominal wall. We planned the extensive reconstruction after preoperative Botox injections. Results The 20x25 cm hernial sack contained parts of the stomach and colon. The dissection of the midline and transverse scars was challenging with the needed removal of scattered pieces of heterotopic bone tissues. After dissecting the retro-muscular space, the fascial edges were 25 cm apart. With bilateral transversus abdominis release (TAR), It was reduced to 20 cm. The posterior fascia was approximated, leaving a central 12 cm defect, and a smaller lateral defect, which we covered using open-IPOM and underlay techniques respectively. A 30x40 cm mesh in sublay position was placed and fascial traction was applied on the anterior fascia. With the resulting defect of 16 cm, a tension-free closure was still not possible, and we bridged the gap with a mesh in inlay position. Conclusions Despite combining pre-operative Botox injection and fascial traction with TAR, complete closure of the fascia was not possible. IPOM, sublay, underlay and inlay bridging were needed. Specialized hernia surgeons should be familiar with a wide range of different techniques to deal with such cases.

Preoperative Progressive Pneumoperitoneum Revisited

Incisional hernia represents a common and potentially serious complication of open abdominal surgery, with up to 20% of all patients undergoing laparotomy subsequently developing an incisional hernia. This incidence increases to as much as 35% for laparotomies performed in high-risk patients and emergency procedures. A rarely used technique for enabling closure of large ventral hernias with loss of domain is preoperative progressive pneumoperitoneum (PPP), which uses intermittent insufflation to gradually stretch the contracted abdominal wall muscles, increasing the capacity of the abdominal cavity and allowing viscera to re-establish right of domain. This assists in tension-free closure of giant hernias which may otherwise be considered inoperable. This technique may be used on its own, or in conjunction with preoperative Botulinum Toxin A to confer paralysis to the lateral oblique muscles. These two complementary techniques, are changing the way complex hernias are managed.

High Abdominal Perfusion Pressure Using Umbilical Cord Flap in the Management of Gastroschisis

Background: Gastroschisis management remains a controversy. Most surgeons prefer reduction and fascial closure. Others advise staged reduction to avoid a sudden rise in intra-abdominal pressure (IAP). This study aims to evaluate the feasibility of using the umbilical cord as a flap (without skin on the top) for tension-free repair of gastroschisis.Methods: In a prospective study of neonates with gastroschisis repaired between January 2018 to October 2020 in Tanta University Hospital, we used the umbilical cord as a flap after the evacuation of all its blood vessels and suturing the edges of the cord with the skin edges of the defect. They were guided by monitoring abdominal perfusion pressure (APP), peak inspiratory pressure (PIP), central venous pressure (CVP), and urine output during 24 and 48 h postoperatively. The umbilical cord flap is used for tension-free closure of gastroschisis if PIP > 24 mmHg, IAP > 20 cmH2O (15 mmHg), APP <50 mmHg, and CVP > 15cmH2O.Results: In 20 cases that had gastroschisis with a median age of 24 h, we applied the umbilical cord flap in all cases and then purse string (Prolene Zero) with daily tightening till complete closure in seven cases, secondary suturing after 10 days in four cases, and leaving skin creeping until complete closure in nine cases. During the trials of closure, the range of APP was 49–52 mmHg. The range of IAP (IVP) was 15–20 cmH2O (11–15 mmHg), the range of PIP was 22–25 cmH2O, the range of CVP was 13–15 cmH2O, and the range of urine output was 1–1.5 ml/kg/h.Conclusion: The umbilical cord flap is an easy, feasible, and cheap method for tension-free closure of gastroschisis with limiting the PIP ≤ 24 mmHg, IAP ≤ 20 cmH2O (15 mmHg), APP > 50 mmHg, and CVP ≤ 15cmH2O.

Ureteric Injury in Gynecology Surgery

It is the most serious and trouble-some complication of pelvic surgery and common reason for medico-legal action by the patient. It can be unilateral or bilateral. Lowest 3 cm of ureter is usually injured. 75% of injuries result from gynecological operations - 3/4th during abdominal and 1/4th during vaginal operations. As most injuries can be diagnosed intraoperatively, systematic assessment of urinary tract integrity should be part of the surgical plan. Intraoperative cystoscopy using either flexible or rigid instruments can aid in the diagnosis or exclusion of urinary tract injury. Identification of the mechanism of injury and its location guides immediate or delayed repair. Mobilization should be sufficient to allow a tension-free closure. Tissue interposition is typically recommended. Common sites for ureteral injury are found beneath the uterine vessels near the cardinal ligament and beneath the infundibulopelvic ligament and the tunnel of Wertheim. Successful ureteral repair relies on careful mobilization, wide spatulation, use of fine absorbable suture (4-0, 5-0), and temporary stenting. Postoperative signs and symptoms of ureteral injury may include unilateral flank pain, fever, prolonged ileus, and abdominal or pelvic fluid collection (urinoma).

Use of a buccinator myomucosal flap and bilateral pedicled buccal fat pad transfer in wide palatal fistula repair: a case report

Primary palatoplasty for cleft palate places patients at high risk for scarring, altered vascularity, and persistent tension. Palatal fistulas are a challenging complication of primary palatoplasty that typically form around the hard palate–soft palate junction. Repairing palatal fistulas, particularly wide fistulas, is extremely difficult because there are not many choices for closure. However, a few techniques are commonly used to close the remaining fistula after primary palatoplasty. Herein, we report the revision of a palatal fistula using a pedicled buccal fat pad and palatal lengthening with a buccinator myomucosal flap and sphincter pharyngoplasty to treat a patient with a wide palatal fistula. Tension-free closure of the palatal fistula was achieved, as well as velopharyngeal insufficiency (VPI) correction. This surgical method enhanced healing, minimized palatal contracture and shortening, and reduced the risk of infection. The palate healed with mucosalization at 2 weeks, and no complications were noted after 4 years of follow-up. Therefore, these flaps should be considered as an option for closure of large oronasal fistulas and VPI correction in young patients with wide palatal defects and VPI.

Mechanisms of Soft Tissue Injury

Soft tissue trauma to the face is challenging to manage due to functional and aesthetic concerns. Management requires careful regional considerations to maintain function such as visual fields and oral competence in periorbital and perioral injuries, respectively. Basic wound management principles apply to facial soft tissue injuries including copious irrigation and tension-free closure. There is no consensus and high-level evidence for antibiotic prophylaxis especially in various bite injuries. Ballistic injuries and other mechanisms are briefly reviewed. Scar revision for soft tissue injuries can require multiple procedures and interventions. Surgery as well as office procedures such as resurfacing with lasers can be employed and will be reviewed.

Repair Exposure of the Postauricular Tissue Expander Using the Modified Brent Method: A 7-Year Experience

Objectives: Ear reconstruction is a challenging surgery for the complicated conditions in patients with microtia. The tissue expansion techniques were necessary and relatively safe for patients with insufficient soft tissue. However, complications such as necrosis of expanded flap and exposure of tissue expander limited the popularization of this method. This study described the use of modified Brent method to handle the exposure of the postauricular tissue expander. Methods: From January 2013 to December 2019, 27 ear reconstruction patients with trauma or necrosis on an expanded skin flap and subsequent exposure of tissue expander were treated with modified Brent method, which consisted of 3 stages: removal of the expander, tension-free closure of wound, and framework fabrication; elevation of reconstructed ear; lobule rotation; and minor modification. Results: Fifty-six percent of exposures occurred in the lower pole of the tissue expander. Exposure usually occurred 54.5 days after implantation. The majority of reconstructed ears had a satisfactory appearance and showed relatively stable outcomes. Only one case of cartilage exposure required revision surgery and was repaired by the temporoparietal fascia. Conclusion: With reasonable distribution of expanded flap, prolonged interval, and sutures under tension-free conditions, complications like the occurrence of trauma or necrosis-induced exposure of tissue expander can be repaired efficiently by a staging modified Brent method.
