Background: In general, the outcomes of arthroscopic repair for superior labrum anterior to posterior lesions (SLAP) are favorable, however, persistent pain and limitation of motion are not rare complications. One of the possible cause is a "knot-ache". This study evaluated the results of reoperation of symptomatic recurrent SLAP lesions and asked whether the knot is associated with postoperative complications. Methods: Between 2005 and 2015, a total of 11 patients who had undergone arthroscopic SLAP repair were reoperated for recurrent symptomatic SLAP lesion. By retrospective chart review, operative findings, the visual analogue scale for pain (pVAS), the range of motion (ROM), and functional scores were analyzed. Results: The mean age of the study participants was 38.3 years, and the mean follow-up period was 42.5 months. In the primary operation, there were nine cases of repairs with conventional knot-tying anchors and three cases with knotless anchors. Impingement of the knots during abduction and external rotation of the shoulder was observed in the all cases with knot-tying anchors. The mean pVAS, ROM, and functional scores significantly improved with reoperation. At the final follow-up, the mean satisfaction VAS was 8.3. Conclusions: The knots of suture anchor maybe a possible etiology of the pain, which we termed a "knot-ache". Considering that reoperation is performed due to pain after primary repair, the use of knotless suture anchor may have benefits of eliminating one of possible cause, "knot-ache". Therefore, authors suggest the use of knotless anchors during reoperation for recurrent or recalcitrant pain after primary SLAP repair.

Purpose: Determining appropriate ways to assess health care quality within the National Health Insurance System is of interest to both the Korean government and the medical community. However, in the trauma field, the number of indicators used to evaluate surgical quality is limited. Using data collected over 5 years at Wonju Severance Christian Hospital Trauma Center in Korea, this study aimed to determine whether the unplanned reoperation rate in the field of trauma surgery could be used to assess the quality of an institution's surgical care. Methods: In total, 665 general surgical procedures were performed at the Trauma Center in 453 patients with abdominopelvic injuries from January 2015 to December 2019. Data were collected from the Trauma Center's data registry and medical records, and included information regarding patients' demographic characteristics, the type of index operation, and the reason for unplanned reoperations. Results: A total of 453 index operations were evaluated. The proportion of patients with an Injury Severity Score (ISS) >15 was 48-70% over the 5-year period, with an unplanned reoperation rate of 2.1-9.3%. Patients had an average ISS score of 17.5, while the average Abbreviated Injury Scale Score was 2.87. Unplanned reoperations were required in about 7% of patients. The most common complications requiring reoperation were recurrent bleeding (26.9%), wound problems (26.9%), intestinal infarction (15.4%), and anastomosis site leakage (7.7%). The procedures most frequently requiring unplanned reoperations were bowel surgery (segmental resection, primary repair, enterostomy, etc.) (24.5%) and preperitoneal pelvic packing (10.6%). Conclusions: The proportion of reoperations was confirmed to be affected by injury severity.

Between January 1981 and January 1991, 554 patients underwent prosthetic valve replacement. A bioprosthetic valve was replaced in 238 cases and mechanical valve 316 cases. Thirty-eight patients underwent 40 reoperations for repair or replacement, an average of 53.6 months after initial implantation. There were 21 women and 19 men, aged 12 to 60 years[mean 35.3]. A bioprosthetic valve was implanted in 31 cases and a mechanical valve in 9 cases for initial operation. Indications for reoperation were primary tissue failure in 23 cases[57.5%], endocarditis in 9[22.5%], periprosthetic leak in 4[10%]. and valve thrombosis in 4[10%]. Operations performed included 5 aortic valve replacements, 26 mitral valve replacement, 8 double valve replacements, and 1 thrombectomy. A mechanical valve was replaced in 33 cases[84.6%] and a bioprosthesis in 6[15.4Zo] for reoperation. A second reoperation was required in 2 patients. Surgical mortality was 10% . Among the 34 early survivors followed-up for an average of 19.8 months. there was 1 late death and 3 were lost to follow-up. Among the 30 late survivors being followed up, 28[93.3%] remained in New York Heart Association Class I or II and two in Class III [6.7%].

We performed a reoperation of failed tricuspid mechanical valve in a 63-year-old female patient because the overgrown endothelial pannus had entrapped the prosthetic leaflets. Four years ago, the patient underwent mitral and tricuspid valve replacements with 31 and 33 mm Carbomedics, respectively. The patient showed symptoms of neck vein distention, abdominal distention and peripheral edema. The chest film, echocardiography and cineangiography confirmed the diagnosis of tricuspid valve. During the operation, we found the entrapped leaflets of the tricuspid valve in a partially closed state and the endothelial pannus had overgrown into the leaflets. Carpentier-Edward bovine pericardial valve was inserted and the patient was discharged with no significant events.

Despite the multivariate improvements in tissue treatment, material, and design of prosthetic heart valves in recent years, numerous complications that may lead to valve dysfunction remain a constant threat after valve replacement. Most common indications for prosthetic valve failure are primary valve failure, infective endocarditis, paravalvular leakage, and thromboembolism. From 1977 to 1986, 15 patients underwent reoperation for prosthetic valve failure in 278 cases of valve surgery. The etiology of prosthetic valve failure were primary valve failure in 12 patients [80 %], infective endocarditis in 2 patients [13.3 %], and a paravalvular leakage [6.7 %]. The average durations of implantation were 45.5 months; 53.9 months in primary valve failure, 16 months in infective endocarditis, and 4 months in paravalvular leakage. The rate of valve failure was high under age of 30 [11/15]. Calcifications and collagen disruption of prosthesis were main cause of primary valve failure in macro- & micropathology. Prosthesis used in reoperation were 5 tissue valves and 10 mechanical valves. Operative mortality were 13.3 % [2/15], due to intractable endocarditis and ventricular arrhythmia.

Tracheoinnominate artery fistula is a rare but a catastrophic complication after tracheostomy or tracheal reconstruction. We experienced two cases of tracheoinnominate artery fistula after tracheal reconstruction and tracheostomy. The first patient was a 11 year old girl with cerebral arteriovenous malformation who maintained tracheostomy for 6 months before undergoing tracheal reconstruction. Three days after tracheal reconstruction, massive bleeding occurred through the intubation tube. She underwent emergency reoperation of repair the innominate artery with 5-0 Prolene and reconstruction of trachea. She died of bleeding 3 days after the reoperation. The second patient was a 68 year old man who underwent right upper lobectomy due to lung cancer. After operarion MRSA Pneumonia was developed and tracheostomy was performed 10 days after intubation. Twelve days after tracheostomy, massive bleeding occurred and emergency operation of ligation of innominate artery was performed. He died of sepsis 7 days after reoperation.

After first successful mitral valvotomy by Harken and Bailey in 1948, improvement of surgical technique and cardiac device may last rapidly for several years, but there after many patients deteriorate because of various causes, so incidence of reoperation for cardiac valvular disease has increased time by time. This paper is concerned with 21 patients in whom a second operation has been carried out from Jan. 1963 to Aug. 1984 at the department of Thoracic and Cardiovascular department, National Medical Center. Of 21 patients, 7 were male and 14 were female, and ages ranged from 14 to 37 years The second operation are classified into groups of secondary closed mitral commissurotomy [3 cases], open commissurotomy following closed mitral commissurotomy [1 case], Valve replacement following closed mitral commissurotomy [14 cases] or bioprosthetic valve replacement [3 cases]. Main cause of reoperation was restenosis or steno insufficiency, and that of bioprosthetic valve failure was bacterial endocarditis [1 case], fibrous tissue overgrowth on the Xenograft [1 case] and technical failure [1 case]. Early operative mortality was absent, but during follow-up, 4 patients died, so late mortality was 19.0%, and main cause of death was congestive heart failure.

We report the case of a female patient who underwent late reoperation following endocarditis surgery. The patient first underwent surgery at 22 years of age for endocarditis with aortic and tricuspid insufficiency. She underwent aortic root replacement with a homograft and tricuspid valve replacement with a tissue valve. Coronary artery bypass using the internal thoracic artery and ligation of the left main coronary artery were performed. Ten years later, failure of the homograft and the tricuspid valve developed. In the second operation, the patient underwent a successful Bentall operation and tricuspid valve replacement with a mechanical valve under deep hypothermia and retrograde cold cardioplegia without drainage.
