Ileal pouch-anal anastomosis. Reoperation for pouch-related complications.

The aim was to assess the value of reoperative surgery for pouch-related complications after ileal pouch-anal anastomosis (IPAA) for chronic ulcerative colitis and familial adenomatous polyposis. Between January 1981 and August 1989, 114 of 982 IPAA patients (12%) seen at the Mayo Clinic had complications directly related to IPAA that required reoperation. Among the 114 patients, the complications prevented initial ileostomy closure in 33 patients (25%), occurred after ileostomy closure in 68 patients (60%), and delayed ileostomy closure in the remaining patients. The salvage procedures performed included anal dilatation under anesthesia for anastomotic strictures, placement of setons and/or fistulotomy for perianal fistulae, unroofing of anastomotic sinuses, simple drainage and antibiotics for perianal abscesses, abdominal exploration with drainage of intra-abdominal abscesses with or without establishment of ileostomy, and complete or partial reconstruction of the reservoir for patients with inadequate emptying. None of the reoperated patients died. Reoperation led to restoration of pouch function in two thirds of patients and, of these, 70% had an excellent clinical outcome. However approximately 20% of the 114 pouches required excision. Excision was common, especially among patients who had pelvic sepsis. Salvage procedures for pouch-specific complications can be done safely and will restore pouch function in two thirds of patients. Complications after reoperation, however, may ultimately lead to loss of the reservoir in one in five patients.

Comparison of primary and reoperative surgery in patients with Crohns disease.

OBJECTIVE: This study was performed to determine the clinical results of patients with Crohns disease who require surgical resection. The outcome of patients undergoing initial surgery was compared with those having reoperation. METHODS: One hundred sixty-four patients undergoing intestinal resection for Crohns disease at The Mount Sinai Hospital from 1976 to 1989 were studied prospectively. The mean duration of follow-up was 72 months. RESULTS: Ninety patients (55%) underwent initial intestinal resection whereas 74 patients (45%) underwent reoperation for recurrent disease. Patients undergoing reoperation were older (33.4 vs. 38.7 years), had longer durations of disease (8.7 vs. 15.2 years), had shorter resections (60 vs. 46 cm), and were more likely to require ileostomy. Forty-seven percent of the patients with multiple previous resections required an ileostomy. This group also received a mean of 2.3 U blood in the perioperative period and showed a trend to increased symptomatic recurrence (49% vs. 71% at 5 years). CONCLUSIONS: Patients with Crohns disease undergoing first and second reoperation have outcomes similar to those in patients undergoing primary resection. Patients requiring multiple reoperations are more likely to require blood transfusions and permanent ileostomy and to show a greater trend to early symptomatic recurrence.

Reoperation rate in diaphyseal tibia fractures.

BACKGROUND: Tibia fractures often require secondary surgery to achieve union. Reoperation is an objective outcome measure that is clinically relevant to the patients and treating doctors. This study determined the complication and reoperation rates for diaphyseal tibia fractures and identified variables predictive of reoperation. METHODS: One-hundred and sixty-seven patients with 175 consecutive tibia shaft fractures (Association for the Study of Internal Fixation classification 42) presenting between July 2000 and June 2003 were included in the study. There were 4 deaths and 12 patients lost to follow up. The remaining 151 patients (159 fractures) were reviewed at a minimum of 6 months post-injury for the main outcome measures; union and reoperation. Univariate and multivariate analyses by logistic regression were used to identify any relationship between revision surgery and fracture classification, grade of the soft-tissue injury, mechanism of injury, age, sex, and treating surgeon. RESULTS: The overall reoperation rate was 35.8% (57/159) with 13.2% (21/159) tibiae requiring minor revision surgery and 22.6% (36/159) tibiae requiring major revision surgery. Thirteen (8.2%) patients underwent major revision surgery specifically for non-union. The fracture classification and the Gustilo grade of soft-tissue injury were significant predictors of revision surgery overall, and of major revision surgery. CONCLUSIONS: Tibial shaft fractures have a high revision rate as a consequence of non-union and infection. Revision surgery is best predicted by the fracture classification and the severity of the soft-tissue injury. This information is important for patient information and clinical decision making.

Reoperation for recurrent coronary artery disease--a ten year experience.

The need for reoperation caused by recurrence of coronary artery disease is becoming increasingly common. Although reoperation is more difficult and time-consuming, with careful surgical technique it can be carried out with the same mortality as that described by many units for primary coronary artery bypass grafting (1.2-2.0%). In the 172 patients described here, who had coronary artery reoperations between 1981 and 1990, there were two in-hospital deaths (1.2%). There were three postoperative bleeds which required return to theatre. No patient suffered a postoperative neurological deficit or postoperative myocardial infarction. These reoperations comprised 6.9% of the 2497 coronary artery operations carried out in the same period. Follow-up disclosed eight late deaths, from five-62 months after operation; all survivors claim to be symptomatically improved. Consideration should be given to the potential problems of reoperation when carrying out primary myocardial revascularisation.

Reevaluation of surgical failures and the role of reoperation in 39 patients with frontal lobe epilepsy.

Between 1929 and 1980, 284 patients with refractory nontumoral frontal lobe epilepsy (FLE) underwent operation at the Montreal Neurological Institute (MNI). We studied 39 patients (14%) who required reoperation. Mean age at the time of first operation was 18 years and at reoperation was 22 years. Clinical manifestations were similar to those of patients with "a pure culture of frontal lobe epilepsy" as reported by Rasmussen in 1983. At the time of first operation, large epileptogenic zones were noted in most patients. Resection was confined to the frontal lobe. Continuing seizure activity was due to residual areas of epileptogenesis, and reoperation with more extensive resection of cortex increased the number of seizure-free patients. Twenty-six patients underwent further frontal resection, and in 13 surgical removal was extended to the temporal lobe. Residual electrocorticographic (ECoG) spiking was documented in 15 of 23 (65%) of the reoperated patients. Thirty-five patients were followed for periods ranging from 4 to 46 years. One fifth became seizure-free, and 31% had significant seizure reduction. Thus, half of these patients had a good result. Patients with residual postexcision ECoG spiking had poor outcomes and evidence of large epileptogenic zones. None of the patients who underwent frontotemporal resections became seizure-free. Reoperation should be considered if initial resection does not lead to a satisfactory result and may convert an initial failure into a good surgical result.

Routine reoperative off-pump coronary artery bypass grafting via midline sternotomy: is it feasible?

Multivessel off-pump coronary artery bypass (OPCAB) has been conducted safely; however, the clinical outcomes of reoperative OPCAB have not been reported clearly. Currently OPCAB is being performed systematically in this institution including reoperative surgeries. Between September 1, 1999, and December 31, 2003, reoperative OPCAB via midline sternotomy was planned for nonemergent patients with normal left ventricular function without valvular disease. The perioperative results of patients who underwent reoperative OPCAB were analyzed. Thirty-five patients were scheduled for OPCAB. Of these, OPCAB was performed in 27 patients, giving OPCAB success rate of 77.1%. Failure of OPCAB was due to graft injury in 2, ischemic EKG change in 1, and dense adhesion and difficulty of dissection in 5 patients. The mean number of grafts with completed OPCAB was 3.0 +/- 1.5. There were no hospital deaths, strokes, or respiratory or renal failures. One patient (3.7%) developed perioperative myocardial infarction. Postoperative angiography was obtained in 12 patients (26 distal anastomoses), and all anastomoses were perfect except for 1 distal anastomosis stenosis, giving an overall stenosis-free patency rate of 95.1%. During a follow-up period (mean 2.5 +/- 0.6 years), all patients survived without cardiac event, except 1 patient who underwent catheter intervention. Cardiopulmonary bypass may be required during cardiac dissection to decompress the heart and to facilitate dissection. However, once lysis of the adhesion is completed, reoperative OPCAB can be performed without increasing surgical risks. Midterm results were satisfactory.

Continuous retrograde cardiac perfusion decreases risk of reoperative coronary artery bypass grafting.

Embolization of atheromatous debris from old saphenous vein grafts is a major factor that increases the risk of reoperative coronary artery bypass grafting (CABG) when compared with primary CABG. To decrease this risk, a technique consisting of minimal dissection of the heart prior to cross clamping, continuous retrograde coronary sinus perfusion with 32 degrees C blood, and temporary posterior cardiac interventricular vein occlusion, during which time all dissection and anastomoses are performed, was evaluated prospectively in 130 consecutive patients from January 2, 1991, through February 28, 1995. This group was compared with a cohort of 1107 patients undergoing primary CABG performed concurrently. The two groups were similar in age (median sixty-eight years), incidence of hypercholesterolemia, peripheral vascular disease, smoking history, and left main stem stenosis. More patients undergoing reoperative CABG had previous myocardial infarctions (61.5% vs 54.5%), a higher incidence of triple-vessel coronary artery disease (89.2% vs 77.1%, P = 0.002), and a lower ejection fraction (54.0% vs 56.9%). The median interval from primary CABG to reoperative CABG was one hundred twenty-seven months with a range of 2.5 to two hundred seventy-nine months. The cross clamp time (median one hundred three vs sixty-nine minutes, P = 0.000001) and perfusion time (median one hundred thirty-four vs ninety-four minutes, P = 0.000001) were significantly higher in the reoperative CABG group. The requirements for inotropic support postoperatively, perioperative myocardial infarction (1.5% vs 2.4%, P = 0.397), and mortality (3.1% vs 3.4%, P = 0.54) were statistically equivalent in the two groups. These data reveal that continuous retrograde coronary sinus perfusion, posterior cardiac interventricular vein occlusion, and single cross-clamping technique improve outcomes of reoperative CABG to that approaching primary CABG.

Inability of computed tomography appearance of recurrent malignant astrocytoma to predict survival following reoperation.

Computed tomographic (CT) scans of 39 patients who underwent reoperation for recurrent malignant astrocytoma at Memorial Sloan-Kettering Cancer Center from 1980 through 1987 were reviewed and correlated with the patients' clinical course. Histologic diagnosis (anaplastic astrocytoma v glioblastoma multiforme) had a statistically significant impact on survival following reoperation (P = .038). Patients with high preoperative performance status (P = .29), total resection by postoperative CT scan (P = .15), and frontal lobe tumors (P = .17) tended to survive longer following reoperation. The size of the tumor at the time of recurrence did not correlate with survival following reoperation. Patients with a small amount of peritumoral edema at the time of recurrence tended to survive longer, but the effect was small (P = .16). Prognosis following reoperation cannot be accurately predicted on the basis of tumor appearance on CT scan.

Reoperation following total repair of congenital heart disease.

For the past 25 years we have performed 61 reoperations in 58 patients with congenital heart disease who previously underwent total correction for the diagnosed ventricular septal defect, tetralogy of Fallot, atrioventricular septal defect, atrial septal defect, total anomalous pulmonary venous connection (TAPVC), and other involvement for 27, 11, 5, 4, 4, and 7 patients, respectively. Causes of reoperation included 43 events of valvular lesion, 29 of residual septal defect, 5 of conduit failure, 5 of venous obstruction, 3 of hemolysis, 3 of infective endocarditis, and 2 of prosthetic valve dysfunction. Although 5 early and 4 late deaths were encountered, the remaining 49 patients (3 in New York Heart Association (NYHA) Class II and 46 in NYHA class I or II) survived the reoperation. The patients were followed up by echocardiography and chest X-ray examination, and reoperation was indicated under the following conditions: moderate to severe valvular insufficiency; residual defect causing the shunt ratio to be over 30% or a systolic pulmonary pressure over 50 mmHg; or a high pressure gradient over 50 mmHg across the right ventricular outflow tract. Early timing for reoperation seemed to be important in patients with pulmonary venous obstruction, prosthetic dysfunction, severe hemolysis and infective endocarditis.

The incidence of reoperations in pacemaker recipients.

OBJECTIVE: To evaluate the incidence of reoperation due to complications or battery depletion in patients who underwent endocardial permanent pacemaker implantation during an 8-year period. METHODS: All pacemaker implantation and related procedures from January 1996 to June 2003 were retrospectively collected and entered into a database. During this time period a total number of 3856 operations with 2242 primary implantations and 1614 redo operations were performed at our department. As 809 patients were referred from another hospital, where the primary operation was done, these patients were excluded from further analysis. The mean follow-up time was 48 months, ranging from 6 to 96 months. RESULTS: A total of 547 patients underwent 805 reoperations during this 8-year period. The most common cause for reoperation was lead malfunction, which occurred in 326 patients (8.4%). Atrial leads were affected more commonly (206 patients, 63%) than ventricular leads (120 patients, 37%). Eighty percent of lead failure occurred during the first 3 months after implantation and was due to dislocation of the lead, whereas the remaining 20% occurred more than 3 months after implantation and were caused by lead fracture, insulation failure, and exit block. Elective replacement indication of a pacemaker was necessary in 312 patients (8%), and pacemaker pocket erosion or infection required reoperation in 167 patients (4%). CONCLUSION: Permanent pacemaker implantation is now accepted as a highly effective and safe procedure. However, cost effectiveness and the relatively simple procedure have to be weighed against the need of reoperations due to system malfunction or replacement indication.

Reoperations of hip fractures.

The incidence and type of reoperations after osteosynthesis of cervical and trochanteric femoral fractures in the city of Göteborg, Sweden was studied from 1965 through 1981. The yearly incidence of reoperations decreased for both types of fractures over the years. Reoperations after cervical fractures were frequent, occurring in about 30 per cent. There were few reoperations after trochanteric fractures on the other hand, 3.6 per cent in 1981. Arthroplasties comprised the greatest number of reoperations, with a fairly constant relative frequency of about 18 per cent during the study period.

Reoperation for recurrent temporal lobe epilepsy.

The indications for the risks and outcome of reoperation for medically refractory temporal lobe epilepsy have not been well documented. A retrospective review is presented of 40 patients who underwent reoperation on the temporal lobe for recurrent seizures. The mean patient age at the first operation was 22 +/- 7 years (+/- standard deviation). Electrocorticography during the first operation showed interictal epileptic abnormalities from surface electrodes in 97% of the cases and from depth electrodes in the mesiotemporal structures in 38%. The seizures recurred with the same pattern within 6 months after the first operation in 60% of patients and within 2 years in 90%. Postoperative neuroimaging studies showed residual mesiotemporal structures in all cases. The mean time between the two operations was 5.5 +/- 5 years and the mean patient age at the second operation was 28 +/- 8 years. The second operation involved focal resection of the mesiotemporal structures in 30 cases. The mean postoperative follow-up period was 4.8 +/- 2.7 years (range 2 to 11 years). After the second operation, 63% of the patients were seizure-free or had rare seizures (one or two per year). There were no permanent neurological complications. Patients who did not benefit from reoperation had electroencephalographic abnormalities in multiple brain areas. Reoperation for temporal lobe epilepsy effectively controls seizures in the majority of patients, and the procedure is safe if rigorous technical rules are observed. More complete resection of mesiotemporal structures during the first operation, even in the absence of intraoperative electrographic abnormalities, could prevent the need for reoperation in defined cases.

Biliary duct reoperations.

Conventional operations for cholelithiasis are rarely associated with postoperative complications. However, when the complications do occur, they are frequently life threatening and require reoperation. These reoperations are associated with a considerably higher risk than primary procedures, and require maximal caution and experience from the surgeon. Reoperations are performed in anatomically altered conditions, and in a patient psychically and physically exhausted and in fear from repeat procedure. Therefore, it is of utmost importance for each primary operation including conventional procedure for cholelithiasis to be carried out at a high professional level, using all technologic achievements available that facilitate and improve the surgeon's work safety. In this way, the need of undesired and hazardous reoperations is minimized. The rate of and indications for reoperation in 530 patients operated on by the conventional procedure for cholelithiasis during the 1994-1999 period are presented.

[Reasons for reoperation after laparoscopic cholecystectomy].

AIMS: Analysis of the reasons for reoperation after laparoscopic cholecystectomy. METHODS AND PATIENTS: Retrospective-prospective analyses of the first 250 patients who undergone laparoscopic cholecystectomy. In 86% cases indication for operation was chronic calculosis of gallbladder. RESULTS: Reoperation was performed at 6 patients (2.4%). The reasons of reoperation were: haematoma of gallbladder's loge (1), biliary fistulas (1), biliary peritonitis (1), abdominal abscesses (2), and perforated peptic ulcer (1). At 2 patients with intraabdominal abscesses, it was solved by laparoscopic drainage. The other complications were solved with laparotomy, also. We did not have lethal cases after reoperation. CONCLUSION: Rate of postoperative complications was 2.4%, and all of them required reoperation. Our results are similar with results of the other authors.

[Reoperation for obstructed extracardiac valved conduit after Rastelli operation].

Between July 1988 and November 2000, 61 patients who were 11.3 +/- 3.8 years old underwent reoperation for obstructed extracardiac valved conduit at 7.0 +/- 2.1 years after Rastelli operation. The right ventricular outflow tract was reconstructed with nonvalved (n = 36) or valved (n = 9) conduit and Danielson's procedure (n = 16). One patient who underwent Danielson's procedure and concomitant aortic valve replacement died in 7 days after reoperation. Mean systolic pressure gradient across the right ventricular-pulmonary artery decreased from 58.6 mmHg to 14.6 mmHg. Re-reoperation was performed in 6 patients after Danielson's procedure for restenosis caused by contracture of xenograft outflow patches. There is no re-reoperation in patients with nonvalved conduit replacement. Postoperative pulmonary regurgitation by UCG was moderate in 12 patients with nonvalved conduit replacement and two with Danielson's procedure. In our experience, reoperation for obstructed extracardiac valved conduit after Rastelli operation is safe and nonvalved conduit replacement provides good midterm results.

Laparoscopic reoperation after failed antireflux surgery.

INTRODUCTION: Laparoscopic surgery for the treatment of gastroesophageal reflux disease has been established as being safe, effective, and the best alternative to continuous life-long medical therapy. Antireflux surgery is not, however, devoid of complications and failures. Treatment of these patients represents a major challenge, especially when reoperation is indicated. PATIENTS: One-hundred consecutive patients had a reoperation in our clinic. Previous antireflux procedures were laparoscopic (52 patients), laparotomy (39 patients), and thoracotomy (9 patients). RESULTS: Peri- or postoperative complications occurred in 30 patients (30%). Operative complications were stomach perforation (14), significant bleeding (6), esophageal mucosal perforation (4), gastrocutaneous fistula (2), small bowel enterotomy followed by fistula (1), and tension pneumothorax (1). Reoperation was required in only 2 patients because of a missed stomach perforation or persistent chest leak. The conversion rate (from laparoscopic to open procedure) was 17% overall. CONCLUSION: Laparoscopic reoperation after a failed antireflux procedure is a major surgical challenge, and it is not devoid of morbidity. The surgeon must have extensive experience in laparoscopic surgery and should be able to perform reoperative open surgery through the abdomen and chest. Laparoscopic redo surgery is feasible with good results. Many patients in whom previous open surgery has failed enjoy the advantages of a laparoscopic redo procedure.

Outcome analysis of reoperations after lumbar discectomies: a report of 22 patients.

Our aim was to analyse causes for persistence of pain after lumbar discectomy and outcome of reoperations. Out of 37 reoperated patients, 22 with a minimum follow-up period of one year were included in this retrospective study concerning the years 1993 to 2000. All patients had previously undergone laminotomy and discectomy and fusion was not required during second operations. Outcome was evaluated according to the modified criteria of Kawabata et al. Overall incidence of reoperation was 6.5%. Reoperations were performed because of recurrent disc herniation in 9 patients, epidural fibrosis in 8, and de novo disc herniation at a different level in 5. Contrast enhanced computerized tomography was used in 17 patients and this might be the reason for misdiagnosis of recurrent disc herniation in the two patients with epidural fibrosis. In patients with de novo disc herniation, symptoms recurred earlier. In 20 patients, satisfactory relief of pain, as well as better outcome could be achieved (p<0.05), but no significant improvement in neurological deficits was observed. Excellent results were obtained more in patients with recurrent disc herniation and poor outcomes correlated with long (> 1 year) time intervals for onset of recurrent sciatica (p<0.05). However, patients with epidural fibrosis were also glad postoperatively for decreased pain severity. Only co-existence of epidural fibrosis and de novo disc herniation predicted an inferior outcome. Although recurrent disc herniation seemed to respond best to surgical treatment, we recommend reoperation when objective preoperative findings indicate the presence of surgically correctable compression regardless of its type.

[Surgical treatment for proximal ascending aortic lesion in Marfan syndrome; retrospective evaluation of the initial surgical technique at late reoperation].

OBJECTIVE: To retrospectively evaluate the initial surgical technique for proximal ascending aortic lesion in Marfan syndrome at late reoperation. MATERIALS AND METHODS: Fourteen Marfan patients who were operated on for annuloaortic ectasia (AAE) with or without type A aortic dissection required reoperation through re-median sternotomy for various reasons in the late postoperative period. Average time interval between the initial operation and the late reoperation was 8.4 years. Reoperative procedures used in this series included re-composite graft replacement in 1 patient, total arch replacement (TAR) in 1, and re-composite graft replacement with TAR in 12. RESULTS: There were 2 in-hospital deaths (14.3%); one patient died of low output syndrome (LOS) after combined Bentall and TAR while the other suffered a sudden death probably due to acute myocardial infarction after combined Cabrol and TAR procedure. Eight patients underwent additional descending or thoracoabdominal aortic replacement in the late postoperative period. CONCLUSIONS: Button technique (Carrel patch technique) with small side hole in the composite graft is the operative procedure of choice for AAE to reduce the risk of complications related to coronary artery anastomosis. Button technique and concomitant TAR that helps to avoid the possibility of reoperation on the aortic arch through re-median sternotomy, is the preferred technique for AAE with type A aortic dissection.
