Iatrogenic vesicovaginal fistula repair-experience at Prince Hussein Urology and Organ Transplant Center

Background: Despite the advances in technology in urology practice, and the surgical approach in dealing with iatrogenic vesicovaginal fistula repair, the most important is to achieve continent rate with minimum morbidity.Methods: From January 2006 to December 2017, the medical records and operative notes of 52 female (mean age 37 year) who had undergone transabdominal transvesical operative repair of their vesicovaginal fistula (VVF) at this institution were reviewed retrospectively. CT urography and diagnostic cystourethroscopy were the modalities of diagnostic tools. Trans-abdominal, transvesical repair with omental flap interposition were performed within 4-6 months in all cases. Patients were evaluated at two to three weeks initially, then at three months interval and later annually.Results: In present study, the most common presentation of VVF was urine leakage through vagina. In two third of the patients the etiology was due to hysterectomy procedure, regarding the location of the fistula, 94.2% of the fistulas located high in the posterior wall of the urinary bladder (supratrigonal), with the mean size of 2.2cm (range 5-25mm). 49 patients had single fistula (94.2%). The mean operative time was 110 minutes (range 60-130 minutes) and the mean post-operative urethral catheterization was 21 days (range 17-24 days). Almost all patients were continent after a mean of five months.Conclusions: Iatrogenic VVF is one of the distressing complications of gynecological procedure; delayed transabdominal transvesical approach with omental flap interposition is associated with excellent and durable results with minor morbidity. Standardization of the technique is a key success in the outcome of the repair.

Open Repair without Esophagectomy for an Aortoesophageal Fistula after Thoracic Stent Grafting / 日本心臓血管外科学会雑誌

An aortoesophageal fistula is a critical condition with high operative mortality. A case of aortoesophageal fistula following thoracic endovascular aneurysm repair is reported. The patient was a 72-year-old man complaining of dysphagia who underwent stent grafting for a saccular aneurysm of the descending aorta that was compressing the esophagus four months earlier. Endoscopic examination showed perforation of the aneurysm into the esophagus with severe stenosis. The aneurysmal sac was filled with thrombus. Aortography demonstrated a type I endoleak from the lesser curvature of the aortic arch, draining into the aneurysmal sac. The patient was afebrile with moderate elevation of C-reactive protein, and the white blood cell count was normal. The patient underwent closure of the aneurysmal entry with healthy aortic wall and replacement of the descending aortic aneurysm with a prosthetic graft. The graft was isolated from the fistula by an omental flap. The patient's postoperative course was uneventful. Computed tomography performed 4 years after the surgery showed shrinkage of the aneurysmal sac. The patient has had a healthy life for 9 years since the operation.

Omental Free Shaped Flap Reinforcement on Anastomosis and Dissected Area (OFFROAD) Following Gastrectomy

The frequency of anastomotic leakage after gastrectomy is reported to be 0.9~8%. To reduce deleterious outcomes of anastomotic leakage, we devised the “Omental Free-shaped Flap Reinforcement On Anastomosis and Dissected area” procedure not only to prevent fatal complications following anastomotic leakage but also to promote vascularity of anastomoses and other expected oncological benefits. This video illustrates the surgical procedure following a totally laparoscopic distal gastrectomy. After completion of the anastomosis, the remaining omentum was mobilized upward and divided into two sections. We placed the left section of the omental flap under the anastomosis between the stomach and pancreas. Finally, we grasped and curved the tip of the section to cover the anastomosis from behind, and we placed the right section of the omental flap above the anastomosis. These two sections were approximated with clips to the anterior wall of the stomach. The patient was discharged without complications.

Pedicle omentum flap harvested by laparoscopy in breast oncoplastic sugery / 中国癌症杂志

Surgery is one of the most important treatments for breast cancer. A part of the early breast cancer patients demand further oncoplastic breast surgery to reconstruct or restore the breast cosmosis after conventional breast conserving surgery, by oncoplastic breast surgery, which is a modern conception and technique including volume dis-placement and volume replacement. Oncoplastic breast surgery using pedicled omental flap is a new approach among volume replacement techniques. It has made some progress in recently years. A systematic review was therefore con-ducted to analyze and illuminate the present status.

Surgical Results for Treating Postpneumonectomy Empyema with BPF by Using an Omental Pedicled Flap and Thoracoplasty / 대한흉부외과학회지

BACKGROUND: Postpneumonectomy empyema (PPE) due to bronchopleural fistula (BPF) can be a surgical challenge for surgeons. We analyzed the follow-up outcomes after performing omentopexy and thoracoplasty for the treatment of PPE with BPF after pneumonectomy. MATERIAL AND METHOD: Between December 1991 and January 2006, 9 patients underwent BPF closure using an omental pedicled flap for the treatment of PPE with BPF after pneumonectomy. There were 7 males and 2 females (mean age: 45.9+/-9 years). The patients were followed up for a mean of 58 months (median: 28 months, range: 6~169). When we performed omentopexy, the surgical procedures for empyema were thoracoplasy for 8 patients and the Clagett procedure for 1 patient. Thoracoplasty was performed for the latter patient due to recurrence of empyema. RESULT: For the 8 patients who were treated by omentopexy and thoracoplasty, there was 1 operation-related death due to sepsis. During follow up, 1 patient, who was treated by omentopexy and a Clagett procedure, died of acute hepatitis 40 months postoperatively. The early mortality was 11.1% (8/9). Of the 8 patients, including the 1 late death patient, successful closure of the BPF were achieved in all patients (8/9) and the empyema was cured in 7 patients (7/8). CONCLUSION: The BPF closure using an omental pedicled flap was an effective method for treating PPE with BPF due to TB-destroyed lung, and thoracoplasty with simultaneous omentopexy was effective and safe for removing dead space if the patient was young and in a good general condition.

Usefulness of Omental Flap for Various Soft Tissue Reconstruction

Extensive and complicated defects on the body call for an omnipotent tool for a perfect reconstruction. Flaps derived from the omentum has many advantages over the conventional flaps. From 1999 to 2004, Omental flaps were applied for various soft tissue reconstructions. Among total 20 total 7 cases were for immediate reconstruction, 2 cases for chronic infection, 3 cases for simultaneous reconstruction of two defects, 4 cases for functional joint reconstruction and 4 cases were for flow- through revascularization. Among these cases, 3 cases were operated with minimal incision harvest technique. There were no complete flap failures, partial necrosis of the distal parts were noted on three cases. The omental flap is indicated on a large contaminated defect reconstruction due to its large size, well-vascularized, and malleable properties. The omental flap provides several additional advantages over other flaps, which are; the availability of the one staged simultaneous reconstruction of two defects with one flap, providing gliding function for the joint motion, and a flow-through characteristics with long vascular pedicle. But there are some serious shortcomings, including a long abdominal scar and intraabdominal problems. However, these are rare and can be minimized with our minimal incision technique. Due to its unique characteristics. the omentum is one of the ideal tissues for the reconstruction of the complicated soft tissue defects due to its unique characteristics.

Ileal W-Neobladder in Women with Bladder Cancer: Early Experience / 대한비뇨기과학회지

PURPOSE: The anatomical and voiding functional outcomes of orthotopic neobladders in women with bladder cancer were investigated. MATERIALS AND METHODS: Since July, 1998, 5 women (median age 64.8) underwent an orthotopic bladder substitution following a radical cystectomy for bladder cancer. The median follow-up was 19.6 months (range 12 to 35). After urethral sparing cystectomy, an ileal W-neobladder was constructed and supported by an omental flap. Both the early and late complications were analyzed. A pressure flow study was performed to evaluate the voiding function, and a radiologic study including a MRI was performed to observe the anatomy. RESULTS: There were no perioperative deaths and no early and late complications related to the surgery except for acute pyelonephritis, which occurred in one patient 22 months after surgery. Four patients were continent day and night and one patient had nighttime incontinence. MRI showed that the urethra was connected to the dependent portion of the neobladder, which was supported by an omental flap in all patients. No recurrence of cancer in the native urethra was noted. All patients were satisfied postoperatively. CONCLUSIONS: Orthotopic bladder substitution after a standard radical cystectomy in women provides satisfactory anatomical and functional outcomes. An omental flap could improve the voiding function by supporting the neobladder and making a urethroneobladder junction located in the dependent portion of the neobladder.

Diaphragmatic Hernia as a Complication of Pedicled Omentoplasty / 대한흉부외과학회지

Pedicled omentoplasty is effective in thoracic surgery, but it is associated with several postoperative complications. A case of diaphragmatic hernia as a complication of pedicled omentoplasty in a 65-year-old male is reported. Because aortoesophageal fistula occurred three months after the patch aortoplasty for mycotic aneurysm of descending thoracic aorta, he underwent ascending thoracic aorta to abdominal aorta bypass surgery with resection of thoracic aortic aneurysm and esophagorrhaphy with wrapping of the esophageal suture line and the stumps of aorta with pedicled omental flap. Three years after the operation, herniation of the stomach developed. The pedicled omental flap was ligated and divided, and the diaphragm defect was repaired.
