First-time-use-of-integra-dermal-graft-as-an-alternative-for-buccal-mucosal-graft-urethroplasty-a-rare-case-report

The use of buccal mucosa grafts in urethral reconstruction for complex anterior urethral strictures has gained popularity over the years with very good outcomes reported in literature. Simultaneously newly launched integra dermal graft is been used as Onlay flap for postoperative hypospadias urethro-cutaneous fistula closure as reported in world wide literature. The aim of this case report is to compare pros and cons of use of Integra Dermal Graft as an alternative to staged Buccal mucosal graft urethroplasty in case of 13 years old boy with multiple postoperative hypospadias fistulae.

Two Cases of Minimally Invasive Right Thoracotomy Approach and Microscope-Assisted Surgery for Mitral Re-Operation; Mechanical Valve Dysfunction in the Late Operative Period / 日本心臓血管外科学会雑誌

Case 1 of stuck valve was an 84 year old man, 25 years after mitral valve replacement (MVR) using a mechanical valve. Case 2 was a 67 year old woman, 18 years after the previous operation. These patients underwent re-do replacement of the prosthesis with a minimally invasive right thoracotomy approach using a microscope. Re-do cardiac surgery is commonly regarded high risk on account of difficulty in peeling the adhension, risk of injury to the heart, lung or large vessels, longer operation time, greater amount of transfusion, higher invasion and longer admission. In both cases however, because of microscope-assist and right thoracotomy MICS technique, we safely and successfully completed the operation without any unplanned troubles. We finally had a good course with a short admission, no perioperative transfusion or no perioperative complication.

Re-do Laparoscopic Hepaticojejunostomy: Technique and Outcomes

Background & Aim: Roux-en-Y hepaticojejunostomy (RYHJ) is the most common treatment done for benign biliary strictures and as a part of for post CDC excision biliary drainage. In the long term follow up, RYHJ stenosis is a dreaded complication, both for the patients and the attending surgeon, in view of the complexity and difficulty in its management. This is traditionally managedby a combination of medical, radiological and open surgical techniques. There are only a few reports describing the management of strictured biliary anastomosis by a laparoscopic technique. The aim of the present study is to describe our experience of laparoscopic re- establishment of biliary continuity(Re-do hepatico-jejunostomy) Methods: Retrospective analysis of prospectively collected data of RYHJ stenosis post benign biliary stricture (BBS) repair and choledochal cyst (CDC) excision, treated by laparoscopic re-do RYHJ, between January 2018 to December 2018 in the department of GI Surgery, GB Pant Institute & Maulana Azad Medical College. Results: 6 patients underwent laparoscopic Re-do RYHJ during the study period. 4 patients developed RYHJ stenosis post open BBS repair and 2 after open CDC excision. The presenting complaints was repeated episodes of fever with jaundice, refractory to medical management. Three patients also had hepatolithiasis.

Advance in re-do pyeloplasty for the management of recurrent ureteropelvic junction obstruction after surgery / 北京大学学报(医学版)

Ureteropelvic junction obstruction (UPJO) is characterized by decreased flow of urine down the ureter and increased fluid pressure inside the kidney. Open pyeloplasty had been regarded as the standard management of UPJO for a long time. Laparoscopic pyeloplasty reports high success rates, for both retroperitoneal and transperitoneal approaches, which are comparable to those of open pyeloplasty. However, open and laparoscopic pyeloplasty have yielded disappointing failure rates of 2.5%-10%. The main causes for recurrent UPJO are severe peripelvic and periureteric fibrosis due to urinary extravasation, ureteral ischemia, and inadequate hemostasis. In addition, failing to diagnose lower pole crossing vessels before or during the primary procedure is also responsible for recurrent UPJO. In addition, poor preoperative split renal function, hydronephrosis, presence of renal stones, patient age, diabetes, prior endopyelotomy history, and retrograde pyelography history were considered as predictors of pyeloplasty failure. The failure is usually defined by persistent pain, persistent radiographic obstruction (infection or stones), continued decline in split renal function, or a combination of the above. And the failure of pye-loplasty often occurs in the first 2 years after the surgery. The available options for managing recurrent UPJO with a salvageable renal unit include endopyelotomy, re-do pyeloplasty, stent implantation, percutaneous nephrostomy, ureterocalicostomy, and nephrectomy. Re-do pyeloplasty has such merits as high successful rates and rare complications, compared with endopyelotomy or ureterocalicostomy. And some investigators think that re-do pyeloplasty should be regarded as the gold standard for secondary therapy if feasible. Open pyeloplasty can enlarge the operating field, facilitate the exposure of the ureteropelvic junction, reduce the difficulty of operation, and thus reduce the occurrence of complications. There are no significant differences among the success rates of re-do pyeloplasty under open approach, traditional laparoscopy and robot-assisted laparoscopy, according to previous reports. However, traditional laparoscopic and robot-assisted pyeloplasty give advantages of cosmetology, small trauma, less postoperative pain, speedy recovery and shorter hospitalization, fewer complications and lower recurrent rates. If the primary pyeloplasty is an open operation in retroperitoneal approach, the traditional laparoscopic and robotic operation with retroperitoneal approach should be considered for secondary repair. The cause of recurrent UPJO should be evaluated before surgery and identified intraoperatively to minimize the possibility of recurrence.

Prospective Comparison of Redo Microvascular Decompression and Percutaneous Balloon Compression as Primary Surgery for Recurrent Trigeminal Neuralgia

OBJECTIVE: To prospectively compare facial pain outcomes for patients having either a repeat microvascular decompression (MVD) or percutaneous balloon compression (PBC) as their surgery for trigeminal neuralgia (TN) recurrence. METHODS: Prospective cohort study of 110 patients with TN recurrence who had either redo MVD (n=68) or PBC (n=42) from July 2010 until September 2016. The mean follow-up was 45.6 months. RESULTS: After redo MVD, 65 patients (95.6%) experienced immediate relief of pain. After PBC, 34 patients (81%) were immediately relieved of their neuralgia. After 1 month, the clinical effect of redo MVD was better than PBC (p 0.05). Patients after PBC who occurred developed herpes simplex (35.7%), facial numbness (76.2%), and annoying dysesthesia (21.4%) more frequently compared with patients after redo MVD who occurred developed herpes simplex (14.7%), facial numbness (8.8%), and hypoesthesia (5.9%) (p < 0.05). The symptoms recurred respectively in 15 patients (22.1%) and 19 patients (45.2%) after redo MVD and PBC within the entire 6-year follow-up period. CONCLUSION: For the patients with TN recurrence, redo MVD was a more effective procedure than PBC. The cure rate and immediate relief of pain were better, and the incidence of complications was lower.

A Surgical Approach for Aortic Valve Replacement in a Patient with a Functional Right Internal Thoracic Artery Graft Located Close to the Posterior of the Sternum / 日本心臓血管外科学会雑誌

A 78-year-old woman who had undergone triple coronary bypass grafting with the right internal thoracic artery (RITA) to the left anterior descending artery 8 years previously was referred to our hospital because of heart failure due to progressive aortic valve stenosis. Coronary angiography showed that all of the coronary grafts were patent, and multidetector-row computed tomography demonstrated the functional RITA graft located close to the posterior of the sternum at the level of the second costal cartilage. To prevent injury of the RITA graft, we initially performed an inverted-L-shaped partial sternotomy extended to the right second intercostal space. After institution of peripheral cardiopulmonary bypass, we performed careful removal of adhesions along the posterior of the sternum under decompressed conditions and accomplished resternotomy safely. The patent internal thoracic artery grafts were never dissected and the patient was cooled to a rectal temperature of 22°C. After aortic crossclamping, myocardial arrest was obtained with systemic hyperkalemia by instilling 40 mEq of potassium chloride into the cardiopulmonary bypass circuit and we successfully performed aortic valve replacement. This method is an alternative approach for re-do cardiac surgery after previous bypass grafting in patients with a functional RITA graft located close to the posterior of the sternum.
