Reoperative parathyroid surgery.

The increasing recognition of hypercalcaemia caused by primary hyperparathyroidism has led to a rise in the number of failed parathyroid exploration. We report a series of 37 parathyroid re-explorations on 33 patients with persistent hypercalcaemia following the failure of their previous parathyroid surgery. Of these patients, 27 have been cured of their hypercalcaemia but 7 are permanently hypocalcaemic. The results of the parathyroid localization tests used in this series are described, and the difficulties of reoperative parathyroid surgery are discussed. The reasons for failure of the original operations are analysed. Many are avoidable. Based on our experience strategies are described for parathyroid localization and reoperative surgery.

Reoperation for biliary tract complications following orthotopic liver transplantation.

Biliary tract complications were analysed after 54 orthotopic liver transplantations performed in 49 patients over a 2-year period. Reconstruction of the bile duct consisted of end-to-end choledochocholedochostomy over a T tube in 47 cases and Roux-en-Y choledochojejunostomy in seven (two for sclerosing cholangitis, one for secondary biliary cirrhosis, four retransplants). The T tube was withdrawn 12-16 weeks after operation in all but two patients (2-3 weeks). There was no intraoperative mortality. Eight patients (16 per cent) died during the first month and the 1-year actuarial survival rate was 75 per cent. Early biliary complications (up to 3 months after operation) consisted of five bilomas, for which ultrasonographically guided drainage was effective in three and surgical drainage necessary in two. Late biliary complications (3 months onwards) consisted of biliary peritonitis following T tube removal (four patients; reoperation was required in all four) and necrosis of the bile duct secondary to a late arterial thrombosis (one). The incidence of reoperation as a result of early biliary complications was low (two patients), but higher for biliary peritonitis following T tube removal.

Recurrence and reoperation after strictureplasty for obstructive Crohn's disease: long-term results [corrected].

Strictureplasty extends the surgical options for the treatment of obstructive Crohn's disease. Over 15 years, 52 patients had 241 strictureplasties at 76 operations with no operative mortality and with septic complications in only two patients (4 percent). Median (range) follow-up was 49.5 (1-182) months. Nineteen patients (36 percent) required a second operation for Crohn's disease between 1 and 57 months after first strictureplasty. Most symptomatic recurrence was caused by new segments of stricturing or perforating disease, and recurrence of Crohn's disease was noted at only nine strictureplasty sites (3.7 percent) in four patients. Seven patients (13 percent) required a third operation for Crohn's disease. Patients undergoing strictureplasty alone were no more likely to require reoperation than those who had a concomitant resection at the first procedure (X2 = 0.619, P > 0.2). The reoperation rates after first and second operations were similar (X2 = 0.021, P > 0.2). Minimal surgery does not appear to lead to an accelerated or additional need for subsequent operation. Strictureplasty provides a safe, effective and rapid procedure to restore patients to good health while preserving the intestine and may be recommended for carefully selected strictures as an adjunct to conventional excisional surgical treatment.

Laparoscopic reoperations after failed and complicated antireflux operations.

Nineteen patients underwent laparoscopic reoperations for failed or complicated antireflux operations from a total of 248 patients with gastroesophageal reflux disease who had been operated on by this approach. Sixteen had been submitted to open surgery and three to laparoscopic surgery over a period ranging from 5 days to 31 years before the study. Three patients had been submitted to two open antireflux surgeries previously. Seventeen patients had recurrent reflux esophagitis after different types of surgeries, and two patients presented with gastric strangulation after fundoplication. The causes of recurrence were: slipped total fundoplications (3), disruption of total and partial fundoplications (6), too-tight total fundoplication (1), too-low (gastric) partial fundoplication (1), Allison procedure (1), partial fundoplication and paraesophageal hernia (2), and unknown (3). The laparoscopic approach was used in 18 patients and a laparoscopic-thoracoscopic approach in 1. The procedures included laparoscopic total fundoplications (11), partial fundoplications (4), transhiatal esophagectomy (1), Collis-Nissen (1), Roux-en-Y gastrectomy and thoracoscopic vagotomy (1), and intrathoracic fundoplication (1). One patient was converted to open surgery. Intraoperative complications included 1 pneumothorax, 1 gastric perforation, and 1 esophageal perforation during the introduction of a Maloney dilator. Mean operative time was 210 min, ranging from 140 to 320 min. Mean hospital stay was 3.1 days after treatment of failed operations and 22 days after treatment of complications. Postoperative complications included subcutaneous infection (1), gastric fistula (1), and liver hematoma (1). The results have been excellent and good in 84.3% of the patients after a mean follow-up of 13 months. We concluded that laparoscopic reoperations are technically feasible with good preliminary results provided that the mandatory expertise is available.

Femoral head vitality at reoperation for femoral neck fracture complications.

In seven patients suffering redisplacement, nonunion or segmental collapse after nailing of femoral neck fractures, subsequent changes in the vitality of the femoral head were studied with tetracycline labeling and 99mTc-MDP scintimetry. At reoperation (total hip arthroplasty), the femoral heads were extracted and sawn into slices which were then analyzed. Vitality before nailing was totally lacking (tetracycline labeling) in one case (nonunion), and in the remaining cases moderate reduction was seen, most pronounced in the apical part of the head. In all cases, scintimetry 1-2 weeks after nailing showed reduced femoral head uptake of 99mTc-MDP, but scintimetry some hours before reoperation showed increased femoral head uptake. Isotope analysis of the slices from the extracted femoral heads showed marked reduction of uptake in the apical part of the head, moderate reduction in the distal and anterior parts, and satisfactory uptake in the posterior part of the head and the foveal region, though with individual variations. It was concluded that there is a genuine increase in uptake (revascularization) later in the course in postoperatively avascular heads, and that the apical part of the femoral head sustains the most pronounced vascular damage in femoral neck fracture and is probably the slowest to revascularize.

Reoperation following failed fundoplication.

Fifty patients reoperated for failed Nissen fundoplication are presented; 29 patients (group 2) were operated between 1983 and 1988 while 21 patients (group 1) were operated before 1983. In group 1, the "slipped Nissen" had been the most frequent cause of reoperation (48%). In group 2, the most frequent causes for the unsuccessful operation were: (1) partial or total disruption of the fundic wrap (62%), (2) slipping of the fundoplication, giving rise to the telescope phenomenon (21%), and (3) creation of a fundoplication which was too low (10%). Refundoplication was performed in cases where the dissection of the previously formed fundic wrap was possible (42/50 = 84%). In group 1, three patients were treated by resection of the cardia, one by an Angelchik prosthesis and one by a distal gastric resection with Roux-en-Y diversion. In group 2, fundectomy was performed in one patient; in another, an Angelchik device was inserted, and in a third patient, fundoplication and proximal gastric vagotomy were performed. The results were excellent or good in 66% of patients in group 1 and in 76% of group 2. Operative mortality was 2% and morbidity, 4%. In conclusion, repeat fundoplication is recommended when reestablishment of the fundic region anatomy is possible during dissection. The operation can usually be performed through an abdominal route. Meticulous preoperative evaluation of the patients including 24-hour pH measurement and manometry is necessary. Good results of refundoplication should be expected in 66%-76% of patients with recurrent disease.

Left thoracotomy approach in reoperative off-pump coronary revascularization: bypass grafting from the left axillary artery or descending thoracic aorta.

OBJECTIVE: Reoperative coronary bypass grafting is at high risk. Particularly in redo cases where the patent graft is running near the midline of the sternum, the graft may be exposed to injury by a median sternotomy and subsequent dissection. Whereas, off-pump bypass grafting from the left axillary artery or descending thoracic artery by a left thoracotomy approach is safe for preventing graft damage. METHODS: From March 1998 to February 2002, we performed off-pump coronary artery bypass grafting by a left thoracotomy approach in 9 patients. The left axillary artery was used as the inflow vessel in 4 cases, and the descending thoracic aorta in 5. RESULTS: The radial artery was anastomosed proximally to the axillary artery in 4 cases and the descending thoracic aorta in one case. The saphenous vein graft was anastomosed proximally to the descending thoracic aorta in 4 cases. Transdiaphragmatic minimally invasive bypass grafting for the right coronary artery was simultaneously performed in 3 cases. Postoperative cardiac events were ventricular arrhythmia in 6 cases and supraventricular arrhythmia in 3 cases. There was no damage to the patent grafts. Postoperative coronary angiography performed in 8 cases revealed all the grafts to be patent without stenosis. Cardiac symptoms were not found after the operation in any of the cases. CONCLUSIONS: These procedures can prevent the injury to patent grafts caused by a median sternotomy, and will be one of the useful strategies for reoperative off-pump coronary artery bypass grafting.

Tranexamic acid reduces blood loss and transfusion in reoperative cardiac surgery.

PURPOSE: The objective of this study was to assess the effect of tranexamic acid (TA), a synthetic antifibrinolytic, on blood loss and the need for transfusion of blood products following repeat cardiac valve surgery. METHODS: After ethics committee approval, 41 patients scheduled for reoperative valve replacement were enrolled in this randomized, double blind, placebo controlled study. Patients were randomized to receive TA (10 g in 500 ml NSaline) or placebo (NSaline) as an iv bolus over 30 min, after anaesthesia induction and prior to skin incision. Intraoperative blood loss was assessed by estimating blood volume on drapes, weighing surgical sponges, and measuring suction bottle returns. Postoperative blood loss was measured from mediastinal chest tube drainage following surgery. Blood products were transfused according to a standardized protocol. RESULTS: Patient demographics were similar for age, sex, cardiopulmonary bypass pump time, cross clamp time, surgical time, preoperative haemoglobin, coagulation profile, and the number of valves replaced during surgery. Tranexamic acid administration reduced intraoperative blood loss [median (range)] from 1656 (575-6270) to 720 ml (355-5616) (P < 0.01) and postoperative blood loss from 1170 (180-4025) to 538 ml (135-1465) (Intent to Treat n = 41, P < 0.01). The total red blood cells transfused (median, range) was reduced from 1500 (0-9300) ml to 480 (0-2850) ml (P < 0.01) in the TA group. In hospital complications and mortality rates were not reduced in the TA group. CONCLUSION: Tranexamic acid reduced blood loss and the need for blood product transfusion and appears to be an effective treatment for patients undergoing reoperative cardiac valvular surgery.

Reoperative coronary artery bypass via left thoracotomy.

The patient was a 49-year-old woman. When she was 39 years old, she underwent coronary artery bypass grafting (left internal thoracic artery to left anterior descending artery, saphenous vein graft to first diagonal branch). At the age 48, she had effort angina. On coronary angiography, triple-vessel disease was found, and she was treated conservatively. Progression of the disease was confirmed with detection of the left circumflex artery associated with jeopardized collateral to the right coronary artery showing total occlusion. The patient underwent reoperation. Since the left internal thoracic artery was patent despite occlusion of the saphenous vein graft, the approach of left thoracotomy was employed. Under cardiopulmonary bypass with ventricular fibrillation and left vent through left atrial appendage, the right radial artery was anastomosed to the left circumflex artery from the descending thoracic aorta, and the right gastroepiploic artery was anastomosed to the right coronary artery (4AV branch). Patency of the bypass was confirmed postoperatively. We consider this operative technique was especially useful for reoperation in cases of a patent internal thoracic artery in which left thoracotomy can be conducted safely.

[Reoperations for persistent or recurrent hyperparathyroidism].

Reoperations for persistent or recurrent primary or secondary hyperparathyroidism are demanding tasks mainly when localization of parathyroid tumor(s) was not successful. These procedures may harbor a risk for the patients and therefore need an expert surgeon who is familiar with even the most difficult situation. Important steps before surgery are confirmation of the diagnosis of persistent or recurrent disease and localization of the source of hormone access. Reoperations should be exclusively performed in centers where expert surgeons, radiologists, endocrinologists and nephrologists are available, as well as special technical equipment.

[Early diagnosis and reoperation in persistent primary hyperparathyroidism].

INTRODUCTION: The persistence rate of primary hyperparathyroidism after cervical exploration was estimated and early diagnosis and reoperation were evaluated in a prospective study. METHODS: Between 1 August 1987 and 31 October 1998, 370 patients underwent surgery. The postoperative course is known in 94.6 % of these patients (follow-up 1 month-10 years, median 24 months). RESULTS: Cervical exploration was successful in 97.5 % (n = 353) of the 361 patients with the first manifestation of primary hyperparathyroidism and in all patients with recurrence or persistence of the disease after initial operation elsewhere. In persistent primary hyperparathyroidism serum calcium levels remained elevated 4 days after surgery (n = 9, 2.5 %). Localization studies, preferably with (99m)Tc-MIBI-scintigraphy were attempted during the first postoperative week and could be performed in 4 patients. Four patients wished the procedure to be performed later. CONCLUSION: Within one week after the initial intervention the diagnosis of persistent primary hyperparathyroidism can be established and localization studies as well as cervical reexploration can be carried out. An interval of 3 months from the initial operation to reexploration of the parathyroid area is recommended if the reexploration is impossible within one week. Mediastinal reoperations or surgical interventions in the neck sparing the perithyroid area may be carried out without consideration of specific intervals.

Pattern of nodal metastasis for primary and reoperative thyroid cancer.

This retrospective investigation was undertaken to clarify the pattern of nodal metastasis in papillary (PTC) and medullary (MTC) thyroid carcinoma. Nodal metastases are associated with recurrence of both PTCs and MTCs. The extent of lymph node dissection is controversial owing to the lack of reliable diagnostic criteria for nodal metastases other than histopathology. Between November 1994 and October 1999 a total of 296 patients (134 PTCs, 162 MTCs) underwent total thyroidectomy in conjunction with a standard resection of at least the cervicocentral lymph node compartment. Of 10,446 sampled lymph nodes, 1641 were positive. All nodes were related to their respective cervicomediastinal compartments. The ipsilateral cervicolateral compartment was involved almost as often as the cervicocentral compartment in primary PTC (29% vs. 32%), reoperative PTC (21% vs. 37%), primary MTC (34% vs. 34%), and reoperative MTC (49% vs. 65%). The contralateral cervicolateral and mediastinal compartments were more rarely affected, and were least affected in the primary setting. From these data was derived an individualized surgical strategy for PTC and MTC. This concept rests on the joint resection of cervicocentral and ipsilateral cervicolateral compartments. Depending on tumor entity, surgical status, and primary tumor diameter, additional compartments may have to be cleared.

Functional results and the risk factors of reoperations after lumbar disc surgery.

Factors such as driving motor vehicles, sedentary occupations, vibration, smoking, previous full-term pregnancies, physical inactivity, increased body mass index (BMI), and a tall stature are associated with symptomatic disc herniations. Fitness and strength is postulated to protect an individual from disc rupture. The objective of our study was to determine the pain levels and differences of functional and economic situations of patients who had undergone one or more than one operation due to lumbar disc herniation and to put forward the effect of risk factors that may be potential, especially from the aspect of undergoing reoperation. Patients who had undergone one (n=46) or more than one operation (n=34) due to lumbar disc herniation were included in the study. It was a prospective study with evaluation on the day the patients were discharged and at second and sixth months after lumbar disc operation. The Oswestry Disability Index (ODI) was used in determining the functional disability associated with back pain; the Prolo Functional Economic Rating Scale (Prolo scale) was used in determining the effect of back pain on functional and economic situations. In the ODI measurements made in the postoperative second and sixth months, significant differences appeared in favor of patients who had undergone one operation (p<0.05). According to the Prolo scale, it was found that the economic situation was better in the sixth month and the functional situation was better in the second and sixth months in patients having undergone one operation (p<0.05). The logistic regression analysis demonstrated that the lack of regular physical exercise was a significant predictor for reoperation (OR, 4.595; CI, 1.38-15.28), whereas gender, age, BMI, occupation, or smoking did not indicate so much significance as regular exercise.

Minimal access reoperative mitral and aortic valve surgery.

Minimally invasive cardiac surgery has allowed surgeons to perform valve procedures with a morbidity and mortality comparable with conventional resternotomy approaches while reducing postoperative ventilatory and intensive care unit requirements and overall hospital length of stay. Additionally, patient satisfaction with rapid recovery, earlier return to work, and improved cosmetic results has pushed the pendulum of reoperative valve surgery towards minimally invasive techniques. We reviewed our institutional data consisting of 129 patients requiring reoperative valve surgery over the past 4 years, which was accomplished using these minimally invasive approaches.

Reoperative surgery for hyperparathyroidism.

The difficulties created by an unsuccessful initial operation can usually be avoided by choosing experienced surgeons, identifying four glands, and selectively excising grossly abnormal parathyroid tissue. Patients with multiple endocrine adenomatosis or familial hyperparathyroidism should have a subtotal parathyroidectomy. Reoperative surgery is difficult and although it is successful in approximately 70 to 80 percent of patients, it is associated with a significant morbidity which includes persistent hypercalcemia, hypoparathyroidism, and nerve injury. Reoperative parathyroid surgery should be done in specialized centers where the sophisticated methods of preoperative localization and surgeons experienced in this field are available.

Parathyroidectomy. Review of 338 consecutive cases for histology, location, and reoperation.

Three hundred thirty-eight consecutive parathyroidectomies for hyperparathyroidism were performed over a 22 year period. There were 53 dialysis patients (31 male and 22 female), 285 patients (165 female and 120 male) with primary hyperparathyroidism, 55 patients (19 percent) with parathyroid hyperplasia, and 230 patients with 236 parathyroid adenomas. The location of the adenomas were right upper in 57, right lower in 59, left upper in 60, and left lower in 60. Forty-three patients of the last 194 operated on had histories of childhood head and neck irradiation (21.6 percent), 34 patients (79.6 percent) had associated thyroid disease, and there were 10 with thyroid carcinomas. In the 285 patients, 54 percent had thyroid disease, and 18 had thyroid carcinomas. Twenty-three patients required reoperation for persistent or recurrent hypercalcemia, and 19 neck reexplorations and 6 mediastinotomies were performed. The identification and biopsy as indicated of all four parathyroid glands at initial neck exploration would have prevented over 70 percent of reoperations.

Complications and reoperation after Nissen fundoplication in childhood.

Over a 10 year period, 429 Nissen fundoplications were performed on children with gastroesophageal reflux. Postoperative complications occurred in 69 children (16 percent), including wrap herniation or breakdown in 29; postoperative bowel obstruction in 18; stricture in 10; intraabdominal abscess and enterocutaneous fistula in 3 patients each; and wound infection, wound dehiscence, and inadvertent splenectomy in 2 patients each. The postoperative mortality rate was 0.9 percent (4 of 429 patients) and was related to sepsis in 1 patient, a metabolic disorder in 1 patient, and underlying pulmonary disease in 2 patients. All four patients were neurologically impaired. Fundoplication successfully controlled symptoms of gastroesophageal reflux in 395 children (92 percent) over a follow-up period ranging from 6 months to 10 years. Thirty-eight patients (8.8 percent) required a second antireflux operation because of recurrent symptoms. Twenty-nine patients had severe neurologic impairment (76 percent), 5 had associated congenital malformations (13 percent), and 3 had significant pulmonary problems (8 percent). Only one child requiring reoperation was considered otherwise normal. Indications for reoperation included wrap breakdown or herniation (28 patients), stricture (6 patients), and inadequate wrap (4 patients). Twenty-four of 28 children with wrap herniation or breakdown had neurologic impairment. A second fundoplication was successful in 35 of 38 patients (92 percent). A second procedure failed in three children, who required subsequent resection and colon interposition.

Late reoperation for systemic atrioventricular valve regurgitation after repair of congenital heart defects.

Since 1979, 17 infants and children have undergone reoperation for systemic atrioventricular (AV) valve regurgitation 6 weeks to 7 years after repair of congenital heart defects. Prior operations were repair of incomplete or complete AV canal (14 patients), Mustard repair of complex transposition of the great arteries including ventricular septal defect closure (2 patients), or first-stage operation for hypoplastic left heart (1 patient). Age ranged from 6 months to 11 years. In 12 of the 17 patients (10, AV canal; 1, transposition; 1, hypoplastic left heart), valve reconstruction was possible. Operative techniques included a combination of septal cleft approximation, leaflet resection, commissural annuloplasty, or ring annuloplasty. There were no operative deaths, and there were no reoperations in the repair group. The condition of these patients has improved. Follow-up ranges from 1 month to 9 years (mean follow-up, 4.1 years). Five of the 17 patients (4, AV canal; 1, transposition) underwent valve replacement. There were no operative deaths. Follow-up ranges from 3 to 8 years. Three patients later underwent re-replacement of the prosthetic valve; there was 1 late death. The condition of all 4 survivors is improved. Substantial AV valve regurgitation can occur months or years after repair of congenital heart defects. A combination of reconstructive techniques may be useful in preserving native valve function and avoiding systemic AV valve replacement.
