Outcomes of a prospective multi-center trial of a second-generation composite mesh for open ventral hernia repair.

PURPOSE: Composite mesh prostheses incorporate properties of multiple materials for use in open ventral hernia repair (OVHR). This study examines clinical outcomes in patients who underwent OVHR with a polypropylene/expanded polytetrafluoroethylene (ePTFE) composite graft containing a novel polydioxanone (PDO) absorbable ring to facilitate placement and graft positioning. METHODS: Data were prospectively collected on consecutive patients undergoing OVHR using a synthetic composite mesh. Seven centers enrolled patients during the study period. All patients underwent a standardized surgical procedure consisting of OVHR with sublay intraperitoneal placement of mesh. Mesh fixation was accomplished with peripheral tacks and transfascial sutures. RESULTS: One hundred and nineteen patients underwent OVHR with the composite mesh. Average age was 55.8 years; there were 71 (59.7 %) females and 48 (40.3 %) males with mean BMI of 33.5 ± 7.1 kg/m(2). One hundred and two (85.7 %) patients presented with primary ventral hernias. Mean defect size was 13.6 cm(2), and mean mesh size was 113.6 cm(2). Most patients (67 %) were discharged the day of surgery. Twelve patients (10.1 %) experienced complications in the perioperative time period primarily consisting of seroma (4.2 %) and ileus (1.7 %). Two patients required reoperation and mesh removal in the early postoperative period for infection and herniorrhaphy site pain, respectively. There was a decline in pain and movement limitation scores between baseline and 1-year follow-up. Six-month (n = 109) and twelve-month (n = 99) follow-up revealed no hernia recurrences (95 % CI 0-3 %, and 0-4 %, respectively). CONCLUSIONS: The use of this second-generation composite mesh was associated with no hernia recurrences and a low complication rate after open ventral hernia repair.

A long-term evaluation of the modified mesh-plug hernioplasty in over 2,000 patients.

BACKGROUND: A modified technique for mesh-plug hernioplasty is a long-term, safe and efficacious treatment for primary unilateral inguinal herniorrhaphy. METHODS: Prospective analysis of 2,038 patients who underwent primary unilateral hernioplasty from 1997 to 2005 at a private university medical center. A modified technique using a mesh-plug was performed under local anesthesia with intravenous sedation. The modified technique consisted of placing the mesh plug into the preperitoneal space and suture fixation of the plug using the inner petals. The main outcome measures were Surgical morbidity, postoperative recovery, hernia recurrence, and chronic pain. RESULTS: There were 1,265 indirect and 773 direct hernias. Mean operative time was 28 min; mean recovery room time, 47 min. A total of 1,936 (95%) returned to normal activities within 3 days. Only 367 patients (18%) required prescription pain medication. Nine patients (0.4%) have been treated for chronic pain. No mesh infections or mesh migration have occurred. Three recurrences (0.15%) have been detected with a 99% follow-up over 2-10 years (mean 72 months). CONCLUSION: The modified mesh-plug hernioplasty is a safe and efficacious treatment option for the primary unilateral inguinal hernia patient.

Prognostic factors relating to esophageal cancer.

Prognostic factors for esophageal cancer are difficult to assess because of the lack of standardization and small number of cases over the years. With the increase in number of adenocarcinoma as well as larger amounts of data, there has been a surge in the amount of information regarding this disease. The most significant relationship is between lymph nodes and survival. As the treatment options for esophageal cancer improve the staging of the lymph nodes will become more important in terms of number and ratio. The method of surgical removal is trending toward radical excision, but the prognosis is still poor. With the advent of molecular markers and better chemotherapeutic agents, we will be able to tailor our treatment with respect to the individual tumor.

A model for tracking student experiences on surgical clerkships.

UNLABELLED: This study was conducted to identify the range and nature of surgical clerkship experiences in three different hospital settings-university, community, and public. METHODS: An instrument was developed to track the location and type of learning experience, patient demographics, surgical content, and clinical experience of students on their surgical clerkship. Twenty-three students used the instrument to record the events of their surgical clerkship. Data were analyzed to describe the frequency of tasks performed, the nature and location of learning experience, exposure to surgical topics, and patient demographics. RESULTS: Students were involved in an average of 245 common surgical tasks over their 8-week clerkship. Of their exposure to common tasks, students had the opportunity to observe 25% and perform 70% of those tasks. Sixty-six percent of task work occurred on the patient floor and 23% occurred in the operating room. Students were exposed to a broad range of surgical topics, 71% of which were general surgery topics. Only 25% of these experiences were auditory, whereas 39% involved exposure to a patient, and 36% included participation in an operation. Patient load and characteristics tended to vary across hospital settings, and on average, students worked with 164 patients during their clerkship. The smallest patient load (m = 113) occurred in the university hospital and the largest patient load (m = 251) occurred in the public hospital. CONCLUSION: Although surgical services and hospital settings may offer students different clerkship experiences, the common clinical and didactic components of a surgical clerkship can balance a student's exposure to surgical topics and practice of clinical skills. Tracking surgical clerkship experiences is valuable in identifying the range and nature of medical students' didactic, clinical, and operative experiences.

A prospective study of the mesh-plug hernioplasty.

A prospective study of patients with symptomatic inguinal hernias was undertaken to determine the safety and efficacy of the mesh-plug hernioplasty. Between May 1, 1997 and March 1, 1999 a total of 309 mesh-plug hernioplasties were performed on 283 patients. There were 43 recurrent and 26 bilateral hernioplasties. There were 273 men and 10 women ranging in age from 15 to 94 years (mean 47 years). There were 199 indirect, 104 direct, and six femoral hernias. Mean operative time for primary hernioplasty was 26 minutes (range 20-34) and 35 minutes (range 31-40) for recurrent hernioplasty. All procedures were performed as outpatient surgery with mean recovery room time being 45 minutes (range 25-27) for primary hernioplasty. Two hundred sixty-six patients (94%) returned to normal activities within 3 days. All manual laborers (124 patients) returned to work without restriction on postoperative day 14. Only 43 patients (15%) required prescription pain medication. At one year postoperatively 283 patients (100% follow-up) have been examined and no recurrence has been detected. At 2 years postoperatively 135 patients (100% follow-up) have been examined and no recurrence has been detected. The mesh-plug hernioplasty uses a minimum of medical resources, is associated with a small amount of postoperative pain, and has an early return to normal activities and manual labor without a documented early recurrence in this study.

Do angiogenesis and growth factor expression predict prognosis of esophageal cancer?

A retrospective study of surgically resectable esophageal cancers was undertaken to determine the relationship between angiogenesis score and growth factor expression with tumor size, histology, degree of differentiation, depth of invasion, nodal disease, and the presence of Barrett's esophagus. The office and hospital charts of 27 patients who had esophageal resection for carcinoma between 1990 and 1995 at Rush-Presbyterian-St. Luke's Medical Center were reviewed. Data collection included patient demographics, survival, tumor size, histology, differentiation, depth of invasion, nodal metastases, and the presence of Barrett's esophagus. The pathology specimens were immunostained for von Willebrand factor (factor VIII-related antigen). Immunostaining was also performed for vascular endothelial growth factor and transforming growth factor alpha. Twenty normal esophageal specimens served as controls. Angiogenesis score was determined by counting vessels under conventional light microscopy at x200 magnification, and growth factor expression was graded on a scale of 1 to 4. Cancers had higher angiogenesis and growth factor expression than controls (P = 0.01). Patient age, tumor size, histology, differentiation, depth of invasion, and Barrett's esophagus did not correlate with angiogenesis score or tumor growth factor expression. Lymph node status did correlate with both angiogenesis score and growth factor expression (P < or = 0.02). We conclude that high angiogenesis score and growth factor expression correlate with the presence of lymph node metastases. This may help select patients for preoperative radiation and chemotherapy or determine the extent of surgery performed for esophageal carcinoma.

Liver resection for colorectal cancer: liver metastases in the aged.

The purpose of this study was to determine the morbidity and mortality in elderly patients undergoing liver resections for metastatic colon cancer and compare them with those of a control group of younger patients. The charts of all patients undergoing liver resection for colon cancer were retrospectively reviewed. Patients less than 70 years of age (Group A) were compared with patients 70 years of age or older (Group B). Between 1971 and 1995, 167 liver resections were performed for metastatic colorectal cancer. Of these, 41 patients were in Group A and 126 patients were in Group B. The mean age of Group A was 74.5 years, and that of Group B was 57 years. American Society of Anesthesiologists (ASA) classification was similar for both groups (Groups A and B were 75.6% and 81.1% ASA class II, respectively). Anatomic resections were performed in 49 per cent and wedge resections in 51 per cent of patients in Group A, and 68 and 32 per cent in Group B, respectively. Estimated blood loss was slightly less for Group A (1575 vs 1973 cm3), as was operative time (4.0 vs 4.7 hours). In-hospital mortality rate was 7.3 per cent for Group A and 2.4 per cent for Group B. The major morbidity rates were 29 and 17.5 per cent, respectively. Intensive care unit care was necessary in 73 per cent (mean length of stay 3.9 days) for Group A and 62.6 per cent (mean length of stay 2.0 days) for Group B. The average length of hospitalization was 13.1 days for Group A and 16.6 days for Group B. The recurrence rates were similar for the two groups [56% (Group A) vs 66% (Group B)], but mean survival was longer for younger patients (22.9 vs 33.5 months). We conclude that liver resection for colorectal cancer liver metastases in properly selected patients older than 70 years of age can be performed with acceptable morbidity and mortality rates. The long-term survival for older patients is less than that for younger patients, but is still a significant length of time. Therefore, we conclude that age alone is not a contraindication to liver resection for colorectal cancer metastases in patients older than 70.

Prognostic factors associated with resectable adenocarcinoma of the head of the pancreas.

A retrospective study of patients with surgically resectable adenocarcinoma of the pancreatic head was undertaken to determine which prognostic factors are independently associated with improved survival. Thirty-four men and 41 women (mean age, 61.9 years) had resection for adenocarcinoma of the pancreatic head between 1980 and 1997 at Rush-Presbyterian-St. Luke's Medical Center. Surgical resections included 15 total pancreatectomies, 43 pyloric-preserving procedures, and 17 standard Whipple procedures. Thirty-six patients received adjuvant radiation and/or chemotherapy. Overall median survival was 13 months, with a 5-year survival of 17 per cent. Thirty-day surgical mortality was 1.3 per cent. Significant factors that negatively influenced survival using univariate Kaplan-Meier analysis were: positive resection margin (P = 0.01), intraoperative blood transfusion (P = 0.01), and lymph node metastases (P = 0.01). Presenting signs and symptoms, patient demographics, operative procedure, tumor size, histologic differentiation, and adjuvant therapy did not have a significant impact on survival. Using multivariate Cox regression analysis, the only significant independent factors improving survival were the absence of intraoperative blood transfusion (P = 0.02) and a negative resection margin (P = 0.04). Performing pancreaticoduodenectomy for adenocarcinoma of the head of the pancreas with negative microscopic margins of resection and without intraoperative transfusion significantly improves survival.

Endoscopic ultrasound for diagnosis and staging of pancreatic tumors.

Endoscopic ultrasound (EUS) is proving to be a useful tool for evaluation of clinically suspected pancreatic masses unsatisfactorily evaluated by other means of imaging. We reviewed the records of 19 patients who had CT and EUS performed for clinically suspected pancreatic masses. Each patient had subsequent surgical exploration. Nineteen patients (11 females and 8 males) presenting with symptoms (11 with obstructive jaundice, 6 with abdominal pain and weight loss) or incidental CT findings suspicious for pancreatic carcinoma underwent EUS for further pancreatic evaluation. All of these patients had exploratory laparotomies, with 13 pancreaticoduodenectomies, 3 distal pancreatectomies and splenectomies, 1 bypass procedure, 1 open pancreatic and hepatic biopsy showing metastatic disease, and 1 open exploration with negative fine-needle aspiration biopsy. EUS correctly identified pancreatic neoplasms in 17 of 19 cases, with two false positives. The tumors included 15 adenocarcinomas, 1 microcystic adenoma, and 1 lymphoma. Node status was correctly predicted in 9 of 12 specimens. Nine of 12 tumors had accurate tumor staging by EUS. Absence of vascular invasion was accurately predicted in 13 of 14 cases. Two patients had metastatic disease discovered at laparotomy. All 19 patients had preoperative abdominal CT scans, with six of these negative for pancreatic masses. EUS is more sensitive than CT in detecting pancreatic masses and is more accurate than CT in locally staging pancreatic tumors. This higher sensitivity is important because those patients with earlier stage tumors are the most likely to benefit from resection.

Mucin Hypersecreting Intraductal Papillary Neoplasm of the pancreas.

Mucin Hypersecreting Intraductal Papillary Neoplasm is a rare neoplasm that arises from ductal epithelial cells. This entity is distinct from the more commonly known Mucinous Cystadenoma or Mucinous Cystadenocarcinoma. Despite this distinction, it has been erroneously categorized with these more common cystic neoplasms. Characteristic clinical presentation, radiographic, and endoscopic findings help distinguish this neoplasm from the cystadenomas and cystadenocarcinomas. Histopathologic identification is not crucial to the preoperative diagnosis. This neoplasm is considered to represent a premalignant condition and, therefore, surgical resection is warranted. Prognosis, following resection, is felt to be curative for the majority of patients. We present two cases of Mucin Hypersecreting Intraductal Papillary Neoplasm and discuss their diagnosis and surgical therapy.

An open, minimally invasive approach to the lumbar spine.

A minimum 2-year follow-up retrospective review was undertaken to assess our experience with an anterior paramedian muscle-sparing approach to the lumbar spine for anterior spinal fusion (ASF). The records of 28 patients (November 1991 through January 1996) undergoing ASF via a left lower quadrant transverse skin incision (6-10 cm) with a paramedian anterior rectus fascial Z-plasty retroperitoneal approach were reviewed. Diagnosis, number, and level of lumbar interspaces fused, types of fusion, estimated blood loss, length of procedure, length of hospital stay, and complications were analyzed. All cases were completed as either a same-day anterior/posterior (24 of 28) or as a staged procedure at least 1 week after posterior fusion (4 of 28). The General Surgery service performed the muscle-sparing approach, whereas the Orthopedic Spine service performed the ASF. There were 14 men and 14 women, with a mean age of 35.5 years (range, 11-52 years). Diagnoses included spondylolisthesis in 20 cases (including four grade III or IV slips), segmental instability (degenerative or postsurgical) in 7, and 1 flatback deformity. A single level was fused in 20 cases (L4/5 in 4 and L5/S1 in 16), two levels were fused in 5 cases (L4/5 and L5/S1) and three levels were fused in 2 cases (L3/4, L4/5, and L5/S1). The mean length of stay was 7.4 days (range, 5-12 days). The mean estimated blood loss was 300 mL for the anterior procedure alone and 700 ml for both anterior/posterior procedures on the same day. The mean length of operating room time for the anterior approach and fusion was 117 minutes (range, 60-330 minutes). Posterior instrumentation was used in all cases. Anterior interbody struts used included 19 autogenous tricortical grafts, 4 fresh-frozen allografts (2 femoral rings and 2 iliac crests), 3 carbon fiber cages packed with autogenous bone, and a Harms titanium cage with autograft. There was one L5 corpectomy for which a large tricortical allograft strut was utilized. There were no vascular, visceral, or urinary tract injuries. In three cases a mild ileus developed, which resolved spontaneously. We conclude that the anterior paramedian muscle-sparing retroperitoneal approach is safe, uses a small skin incision, avoids cutting abdominal wall musculature, and allows for multiple-level anterior spinal fusions by a variety of interbody fusion techniques. This approach does not require transperitoneal violation or added endoscopic instrumentation, nor does it limit fusion level and technique of fusion, as is the case with the recently popularized laparoscopic approach to the lumbar spine.

A prospective experience with selective cholangiography.

A prospective study of patients with symptomatic cholelithiasis was undertaken to determine the effectiveness of identifying clinically significant choledocholithiasis with selective cholangiography. Between 1991 and 1995, 262 patients presented to the senior author (K.W.M.) with acute or chronic cholecystitis. Sixteen patients had a preoperative endoscopic retrograde cholangiopancreatography (ERCP) for an elevated alkaline phosphatase or total bilirubin greater than twice the normal value or an ultrasound finding suspecting choledocholithiasis. Ten of the ERCP patients had choledocholithiasis, with eight patients having successful clearance by ERCP. Ninety other patients had intraoperative cholangiography for abnormal serum liver biochemistries, a history of jaundice or pancreatitis, or a dilated common bile duct (CBD) (>6 mm) on ultrasound. Fourteen of the intraoperative cholangiography patients and the two remaining ERCP patients had choledocholithiasis requiring CBD exploration for clearance of their stones. There were no false-positive cholangiograms, and there were no bile duct injuries in this series. With 100 per cent follow-up of at least 2 years, only one patient required ERCP clearance of a retained CBD stone 13 months after cholecystectomy. The positive predictive value and the negative predictive value for the selective cholangiography criteria are 23 per cent and 99 per cent, respectively. In conclusion, clinically significant choledocholithiasis can be found effectively with selective cholangiography. Also, utilizing selective cholangiography reduces the number of routine cholangiograms by 60 per cent.

Repair of tracheal defect with Goretex graft during resection of carcinoma of the esophagus.

Repair options for tracheal defects secondary to tumor or trauma have been unsatisfactory for emergent cases. We report a case in which the tracheobronchial tree was entered during resection of carcinoma of the esophagus and emergently repaired with a Goretex graft. The patient did well for 22 months after esophagectomy, at which time the graft was found to be infected and was removed. The patient continues to remain free of tumor 4 years after initial resection.

Intraoperative ultrasound in the management of liver neoplasms.

The purpose of this study was to determine the impact of intraoperative ultrasound (IOUS) on the management of patients with neoplasms of the liver. Fifty-nine patients with liver neoplasms (primary, 6; metastatic, 53) and without pre- or intraoperative evidence of extrahepatic disease underwent laparotomy for possible liver resection. Preoperative imaging studies included external ultrasound (n = 12), magnetic resonance imaging (n = 11), and/or computed tomography (n = 57). Intraoperative evaluation on all patients included inspection, bimanual palpation, and ultrasonography. External ultrasound, magnetic resonance imaging, and computed tomography identified all intraoperatively confirmed liver neoplasms in 33, 45, and 67 per cent of cases, respectively. Unsuspected neoplasms were identified in 12 patients (20%) by inspection/palpation and in 19 patients (32%) by IOUS. In eight patients (14%), the occult neoplasms were identified only IOUS, and in one patient the neoplasms were identified only by inspection/palpation. Occult neoplasms identified by IOUS were characterized by small size (less than 2 cm). Findings from the intraoperative evaluation, such as unsuspected neoplasms and vascular proximity or invasion, altered the preoperative plan in 20 (34%) patients. Inspection, and particularly palpation, identifies a number of preoperatively unsuspected liver neoplasms. Intraoperative ultrasound, however, is the most sensitive method for detection of liver neoplasms and influences the operative management in a substantial number of patients.

Hepatic resection for metastatic colorectal cancer.

One-hundred thirty-one primary hepatic resection for colorectal secondary tumors were performed at Rush-Presbyterian-St. Luke's Medical Center between 1975 and 1993. Perioperative mortality occurred in five patients (3.8%). Twenty-three patients had minor morbidities (18%); major morbidity occurred only in the five patients who died. Curative resections were performed in 107 patients. Overall actuarial survival at 2, 3, and 5 years was 62, 42, and 25 per cent, respectively. Patients with extrahepatic disease (5-year survival, 0% vs 27%; P = 0.049) and positive resection margins (0% vs 30%; P < 0.001) had significantly poorer survival. Among the curative resections, patients who had metachronous hepatic resections did significantly better than those who underwent synchronous colon and hepatic resections (35% vs 13%; P = 0.002). This survival benefit persisted when comparison was restricted to patients with synchronous metastases. Age, sex, race, number of lesions, site of colon primary resection, blood transfusion, disease-free interval, and extent of resection had no effect on survival. All patients who are acceptable surgical risks with potentially resectable metastatic colorectal cancer confined to the liver should undergo exploration. Assessment of resectability should include intraoperative ultrasound in all patients to maximize the probability of tumor clearance.

Integration of surgery in multimodality therapy for esophageal cancer.

BACKGROUND: While adding chemotherapy to radiation for the treatment of esophageal cancers has been shown to be beneficial, surgery usually follows treatment or is omitted. In either case, regional control remains problematic. The purpose of this study was to test the feasibility of using chemotherapy and radiation following surgery in the treatment of of esophageal cancer and to assess the impact of this approach on regional control and survival. PATIENTS AND METHODS: Twenty-five patients with esophageal cancer were treated in a phase I pilot protocol consisting of initial esophagectomy with gastroesophagostomy and subsequent combined chemotherapy and radiation. Chemotherapy consisted of cisplatin given on day 1 and 5-fluorouracil (FU) on days 1-5 by continuous infusion. Radiation therapy was administered in varying fractionation schedules of once or twice daily concomitantly with the chemotherapy. Treatment was repeated every other week for two to four cycles. Median follow-up was 42 months. RESULTS: Acute toxicities (mucositis and cytopenias) were common but not worse than grade 3. Higher doses of 50 Gy with 2 Gy b.i.d. hyperfractionation caused late complications in four of 10 patients, (two lethal). Control of local disease for all patients was excellent with only two known and two possible local recurrences (16%) but distant metastases were common (46%). Disease-free survival was 58 and 30% at 1 and 2 years, respectively. Survival was 58 and 32% at 1 and 2 years, respectively (median survival, 19 months). CONCLUSION: The local control rate and survival were better than those in our historical experience with cisplatin and 5-FU chemotherapy and radiation given prior to surgery. A dose-fractionation schedule of < 2 Gy up to a total of 50 Gy b.i.d. is recommended to avoid late adverse effects. The role of surgery will be defined by randomized studies. Better systemic therapy is needed to impact on systemic failure.

Invasive therapy of metastatic colorectal cancer to the liver.

Resection, when possible, is still the best hope for cure of colorectal metastasis to the liver. Poor prognostic indicators for survival include heavy tumor burden, the presence of extrahepatic disease, synchronous metastasis, and the inability to perform resection with a 1-cm margin. Questionable poor prognostic indicators include multiple metastases (more than three), bilobar disease, and the need to transfuse patients during resection. Preoperatively, a patient must be evaluated for the extent of liver disease and the presence of extrahepatic disease with a CT of the abdomen and routine studies of the chest. Intraoperatively, a surgeon should be able to perform or obtain ultrasonography of the liver to detect occult metastases and delineate anatomy. The surgeon should be experienced in wedge, segmental, and lobar resection. Equipment for cryotherapy and arterial infusion devices should be available, and staff experienced in these modalities should be present. If all of these factors are present, the options for the invasive treatment of colorectal metastasis to the liver can be carried out in a manner that should provide the most benefit at a low morbidity to this population of patients.

Superior mesenteric and portal vein thrombosis following laparoscopic-assisted right hemicolectomy. Report of a case.

PURPOSE: This article describes a case of superior mesenteric and portal vein thrombosis following laparoscopic-assisted right hemicolectomy. METHODS: A retrospective case review was performed. RESULTS: Data continue to grow regarding safety and technical feasibility of laparoscopic-assisted colectomy. As this minimally invasive alternative to open colonic resection becomes more popular, it is inevitable that information on benefits and complications associated with it will continue to expand. We report a case of superior mesenteric and portal vein thrombosis following laparoscopic-assisted colon resection. To our knowledge, this represents a complication of laparoscopic colon resection not previously reported in literature. CONCLUSION: Careful patient selection for this procedure is important. Additionally, the incision for extracorporeal resection and anastomosis in laparoscopic-assisted colectomy must be planned appropriately and carefully monitored intraoperatively to avoid potential complication of vascular trauma leading to mesenteric vein thrombosis.

Survival after repeat hepatic resection for recurrent colorectal hepatic metastases.

BACKGROUND: This is a retrospective clinical study done to examine survival of patients undergoing repeat hepatic resection for recurrent colorectal hepatic metastases. METHODS: The records of 131 patients undergoing hepatic resection for metastatic colorectal cancer were reviewed. Curative resection was performed in 107 of these patients. Thirty-one experienced recurrences confined to the liver. Thirteen (13 of 107, 12%) of them underwent resection and make up the study population. RESULTS: The eight men (62%) and five women (38%) had a median age of 60 years (range, 32 to 75 years). In 30% of patients recurrence developed near the original resection site. In 70% the recurrences were remote from the original site. The patients underwent a total of six wedge resections, two left lateral segmentectomies, three right lobectomies, and two trisegmentectomies. Average blood loss was 2995 cc; average hospital stay was 17.2 days. Morbidity was 23% (3 of 13); mortality was 8% (1 of 13). Four patients died of recurrent disease, with a mean disease-free survival of 9.7 months (median, 7.5 months; range, 3 to 21 months) and mean total survival of 39 months (median, 24 months; range, 8 to 99 months). One of these patients had a second recurrence resected at month 21 and lived an additional 78 months. Seven patients were alive with no evidence of disease, with a mean follow-up time of 34.9 months (median, 14 months; range, 1 to 186 months). Actual 5-year survival was 23% (3 of 13). Actual disease-free 5-year survival was 15% (2 of 13). CONCLUSIONS: In properly selected patients morbidity, mortality, and survival after repeat resection are similar to those after initial resection.

The management of hernia. Considerations in cost effectiveness.

Approximately 700,000 herniorrhaphies are performed annually in the United States for primary, recurrent, and bilateral inguinal hernias. This article describes the components of cost regarding the approach and management of groin hernias. The trends toward outpatient procedures, regional anesthetic agents, and early return to work are analyzed. The common types of repair are compared with reference to recurrence and complication rates. The advances and results of laparoscopic hernia are reviewed. In summary, a cost-effective approach for the management of inguinal hernias is presented that could reduce the yearly cost of hernia repair by hundreds of millions of dollars.
