Are esophagocrural sutures needed during laparoscopic fundoplication: A prospective randomized trial.

PURPOSE: Historically, fundoplication has been performed with extensive dissection of the esophageal attachments to the diaphragm. Previously, we conducted a randomized trial demonstrating that minimal esophageal dissection and mobilization reduce the rate of wrap herniation and the need for reoperation. In that study, four esophagocrural (EC) sutures were placed in both groups to help obliterate the space between the esophagus and diaphragmatic crura. In this current study, we evaluate the need for these EC sutures. METHODS: Children less than age 7 undergoing laparoscopic fundoplication were randomized to receive four EC sutures or none. Exclusion criteria included an existing hiatal hernia. The primary outcome was transmigration of the fundoplication wrap through the esophageal hiatus into the mediastinum. A contrast study was performed around 1year postoperatively. Telephone follow-up was performed at a minimum of 1.5years. RESULTS: 120 patients were enrolled from 2/2010 to 2/2014, and 13 did not survive. One patient was excluded because a hiatal hernia was found at laparoscopy, leaving 52 patients with EC sutures (S) and 54 without EC sutures (NS). Operative time was 20min longer in the S group (P<0.01). Contrast studies were obtained in 62% of S and 68% of NS patients, and there were no wrap herniations in either group. There was one reoperation for wrap loosening in the NS group, none in the S group. Final telephone and clinic follow up was at a median of 4years (IQR 3-4.7). Reflux symptoms and medications were not different at one month, one year, and final follow-up. CONCLUSION: When minimal phrenoesophageal dissection is performed, EC sutures offer no advantages and increase operating time. LEVEL OF EVIDENCE: Level II.

When a Surgical Colleague Makes an Error.

Professionalism requires that doctors acknowledge their errors and figure out how to avoid making similar ones in the future. Over the last few decades, doctors have gotten better at acknowledging mistakes and apologizing to patients when a mistake happens. Such disclosure is especially complicated when one becomes aware of an error made by a colleague. We present a case in which consultant surgeons became aware that a colleague seemed to have made a serious error. Experts in surgery and bioethics comment on appropriate responses to this situation.

Minimal vs. maximal esophageal dissection and mobilization during laparoscopic fundoplication: long-term follow-up from a prospective, randomized trial.

PURPOSE: We have previously conducted a prospective randomized trial (PRT) comparing circumferential phrenoesophageal dissection and esophageal mobilization (MAX) to minimal dissection/mobilization (MIN). The MIN group had a decreased incidence of postoperative wrap herniation and need for reoperation. This study provides long-term follow-up of the patients from our center who participated in the PRT. METHODS: Parents of patients in the PRT were queried regarding symptoms, medication use, postoperative complications, and additional procedures. Medical records were reviewed. Student's t-test was used for continuous variables. Fisher's exact and chi-square with Yates correction were used where appropriate. RESULTS: Of patients from our center, 75.4% MAX and 72.5% MIN patients were contacted. Median time to follow-up was 6.5 years. A rise in the incidence of herniation was noted in both groups (22.7% to 36.5% MAX vs 2.8% to 12.2% MIN). Time to diagnosis of hernia was significantly longer in the MIN group (14.7±9.5 months MAX vs 30.2±23.6 months MIN, P=0.04). There was no significant difference between MIN and MAX group in reflux symptoms or medication use. CONCLUSION: Long-term follow-up demonstrates an increase in incidence of herniation in both groups. Previously demonstrated higher risk of wrap herniation with maximal esophageal dissection during laparoscopic fundoplication remains supporting original findings.

Implications of early sonographic evaluation of parapneumonic effusions in children with pneumonia.

OBJECTIVE: To devise a clinically relevant grading system for the sonographic evaluation of parapneumonic effusions, and to evaluate length of hospital stay as a function of treatment approach and sonographic grades. METHODS: Chest sonograms of 46 pediatric patients diagnosed with empyemas and admitted to two medical centers in the last 8 years were retrospectively evaluated using a grading system based on the degree of fibrinous organization within the parapneumonic effusions. Hospital charts were reviewed to determine the method of treatment and length of hospital stay. Patients were divided into two treatment groups: nonoperative (n = 26) (antibiotics alone, or combined with thoracentesis, or tube thoracostomy) and operative (n = 20) (open decortication, or video thoracoscopy and pleural debridement). Patients in the nonoperative group were further subdivided into two groups: those who received antibiotics alone (n = 11) and those who received antibiotics plus nonoperative drainage thoracentesis and/or tube thoracostomy (n = 15). Within each treatment group, patients were subdivided into two ultrasound grades: low (no evidence of organization) and high (evidence of organization such as fronds, septations, or loculations). Student's t test was performed to compare the lengths of hospital stay for each of the treatment groups and ultrasound grades. RESULTS: The length of hospitalization was no different for patients with low-grade ultrasounds in the nonoperative (9.8 days) and operative groups (8.0 days). In contrast, length of hospitalization was significantly shorter for patients with high-grade sonograms in the operative group (8.6 days), when compared with the nonoperative group (16.4 days). Length of hospitalization for patients in the nonoperative group with high-grade sonograms was significantly longer (16.4 days) than for those with low-grade ultrasounds (9.8 days). Furthermore, when the nonoperative patients were divided into an antibiotics alone group and a nonoperative drainage group, the patients with low-grade sonograms had no difference in the length of hospitalization (9.0 days vs. 10.4 days), whereas those patients with high-grade sonograms in the nonoperative drainage group had a significantly longer hospitalization (19.9 days) than the antibiotics alone (high-grade) group (11.4 days). CONCLUSIONS: Patients with a low-grade sonogram had similar length of hospitalization if treated with either nonoperative or operative measures. Patients with high-grade sonograms had significantly shorter length of hospitalization when treated with decortication. Our retrospective study suggests that patients with high-grade ultrasound studies treated nonoperatively do not benefit from pleural drainage procedures or chest tube placement. This study demonstrates the usefulness of early sonographic evaluation of parapneumonic effusions. A prospective study evaluating the usefulness of sonographic assessment of severity of disease in the treatment of children with parapneumonic effusions is warranted on the basis of our retrospective data.

Parapneumonic empyema in children: decortication hastens recovery in patients with severe pleural infections.

The medical records of 61 children 0 to 18 years of age treated for empyema complicating pneumonia from 1977 to 1989 were reviewed with attention to clinical presentation, bacteriology, treatment and outcome. Streptococcus pneumoniae was the most common infecting organism, followed by Staphylococcus aureus, other streptococcal species, anaerobes, Haemophilus influenzae type b, Pseudomonas aeruginosa, and Eikenella corrodens. No organisms were recovered in 39% of patients. Twelve patients were treated successfully with antibiotics and thoracentesis alone, 23 patients underwent close tube thoracostomy and 26 required decortication. A thickened pleural "peel," scoliosis and opacification of a hemithorax on chest radiograph, as well as low pleural pH and glucose concentration, were associated with a poor response to medical management. A scoring system was developed to define the severity of pleural disease. In patients with severe pleural infections, decortication allowed more rapid defervescence (2.2 vs. 6.5 days) and earlier hospital discharge (4.4 vs. 12.4 days) than did closed tube thoracostomy (P less than 0.001).

Primary hyperparathyroidism in a hypothyroid child.

Congenital hypothyroidism may result in severe mental retardation if this condition is not diagnosed in the neonatal period. Primary hyperparathyroidism in children is even more uncommon, and by 1977 had been reported in only 60 children under the age of 16 years. To our knowledge, we are reporting the first child with both congenital hypothyroidism and primary hyperparathyroidism. Because the normal anatomic relationship of the parathyroid glands to the thyroid gland was absent, preoperative localization studies were necessary. Ultrasonography, radionuclide scanning, and magnetic resonance imaging all indicated a right paratracheal mass in the region where the right lobe of the thyroid gland should be located. At operation, a single, enlarged parathyroid gland that measured 1.5 X 1.2 X 0.5 cm and weighed 500 mg was removed. The discharge serum calcium level was 9.3 mg/dl and has remained normal 2 years later.

Minimally invasive repair of pectus excavatum: a single institution's experience.

BACKGROUND: The Nuss repair of pectus excavatum is a relatively new, minimally invasive surgical (MIS) alternative to the traditional open "Ravitch-type" operation. We have one of the larger single-center experiences to date, and we conducted this clinical study to evaluate our early experience, emphasizing initial outcome and technical modifications designed to minimize complications. METHODS: A retrospective chart review was performed on 112 patients who underwent 116 pectus excavatum repairs between January 1995 and January 2001. The Nuss procedure was performed in 80 patients, and open repair was performed in 32 patients. Information about demographics, deformity, operative course, complications, and early outcome was recorded. RESULTS: Operative duration was 143 minutes for the open group and 53 minutes for the Nuss MIS group (P <.001). Blood loss was 6 mL/kg for the open group and 0.5 mL/kg for the MIS group (P <.001). Postoperative hospitalization was 3.2 days for the open group versus 3.7 days for the MIS group (P<.05). CONCLUSIONS: The MIS pectus repair can be performed safely with minimal blood loss and reduced operative time. Short-term analysis of the quality of repair, including absence of preoperative symptoms, patient satisfaction, and cosmetic appearance are encouraging.

Vascular anomalies and tracheoesophageal compression: a single institution's 25-year experience.

BACKGROUND: Vascular rings are uncommon anomalies in which preferred strategies for diagnosis and treatment may vary among institutions. In this report, we offer a description of our approach and a review of our 25-year experience. METHODS: A retrospective review was conducted of all pediatric patients with symptomatic tracheoesophageal compression secondary to anomalies of the aortic arch and great vessels diagnosed from 1974 to 2000. RESULTS: Thirty-one patients (38%) of eighty-two patients (mean age, 1.7 years), were identified with double aortic arch, 22 patients (27%) with right arch left ligamentum, and 20 patients (24%) with innominate artery compression. Our diagnostic approach emphasized barium esophagram, along with echocardiography. This regimen was found to be reliable for all cases except those with innominate artery compression for which bronchoscopy was preferred, and except those with pulmonary artery sling for which computed tomography or magnetic resonance imaging, in addition to bronchoscopy, were preferred. Left thoracotomy was the most common operative approach (70 of 82; 85%). Ten patients (12%) had associated heart anomalies, and 6 (7%) patients underwent repair. Complications occurred in 9 (11%) patients and led to death in 3 (4%) patients. CONCLUSIONS: In our practice, barium swallow and echocardiography are sufficient in diagnosing and planning the operative strategy in the majority of cases, with notable exceptions. Definitive intraoperative delineation of arch anatomy minimizes the risk of misdiagnosis or inadequate treatment.

Laparoscopic evaluation for a contralateral patent processus vaginalis: part III.

OBJECTIVES: Between May 1, 1992 and August 1, 1996, 759 consecutive children younger than 10 years of age were evaluated and treated for known inguinal hernia. These children were participating in a prospective investigation of the potential role of diagnostic laparoscopy in the evaluation of the contralateral inguinal anatomy. The initial two series of data (parts I and II of this three-part series) were previously presented at the 1993 and 1995 American Academy of Pediatrics meetings. METHODS: Of 759 patients, 100 children were diagnosed with bilateral inguinal hernias and therefore did not undergo laparoscopy. Thirty-two patients did not undergo laparoscopic evaluation due to technical difficulties or complicated clinical situations. The patient's contralateral inguinal region was carefully examined under anesthesia, and predictions were made regarding the likelihood of contralateral patent processus vaginalis (CPPV). Six hundred twenty-seven children underwent diagnostic laparoscopy to confirm the presence or absence of CPPV. Laparoscopy was initially exclusively performed through the umbilicus prior to repair of the known hernia, but over the last 26 months, 250 children successfully underwent laparoscopy through the ipsilateral hernia sac. RESULTS: Of patients younger than 1 year of age, 114 were diagnosed with both a known unilateral hernia and CPPV, whereas 132 had a unilateral hernia only (46% versus 54%). Among children older than 1 year of age, 148 (39%) were diagnosed with unilateral hernia and CPPV, and 233 (61%) were diagnosed with a unilateral hernia alone. After examination under anesthesia, 233 of the 627 patients were suspected of having a CPPV, and 107 were confirmed at laparoscopy (46%). The remaining 394 patients were not believed to have a CPPV. Normal inguinal anatomy was confirmed in 234 patients (59%), but 160 patients were found at laparoscopy to have a CPPV (41%). CONCLUSIONS: A contralateral patent processus vaginalis may be present in a surprising number of young patients being evaluated for a known inguinal hernia. Laparoscopy can be performed without a separate incision when the ipsilateral hernia sac is of sufficient width to allow passage of the scope. Laparoscopy is the best method for evaluating the contralateral inguinal region, particularly in younger children, as it prevents unnecessary inguinal exploration and it decreases the risk that the child will later present with a clinical contralateral hernia.

Laparoscopic surgical treatment of achalasia.

BACKGROUND: The authors have performed 11 myotomies in 10 patients (aged 12 to 77) with achalasia using minimally invasive techniques. METHODS: The initial 3 patients were treated via transthoracic approach; the subsequent 7 patients via transabdominal approach. The length of the myotomy was determined in conjunction with intraoperative endoscopy to facilitate dissection and demonstrate division of the lower esophageal sphincter. RESULTS: Only 1 patient required intravenous and intramuscular narcotics more than 24 hours postoperatively; 2 patients required no postoperative narcotics. The average hospital stay for those patients successfully treated endoscopically averaged 2.0 +/- 0.5 days (range 1.5 to 3). One patient was converted to open thoracotomy secondary to perforation of the mucosa. One patient required repeat laparoscopic myotomy at 3 months due to recurrent dysphagia. Follow-up conducted at clinic visits showed all patients to have benefitted with relief of dysphagia; 80% (8) reported excellent results, 10% (1) reported good results, and 10% (1) fair results. CONCLUSION: We converted from thoracic to laparoscopic myotomy because the abdominal approach simplified anesthetic and surgical management. We conclude that laparoscopic myotomy is a simple and effective treatment of achalasia.

Acute abdominal conditions in children and adolescents.

Evaluation and management of the acute abdomen in childhood require a thorough familiarity with the numerous disorders that may cause abdominal emergencies. Many of these entities are rarely seen in adults or have clinical features that are very different from those observed in adults. Diagnosis is often confounded by difficulties in obtaining an accurate history and physical examination. In infants and young children, complications of various congenital abnormalities are more common causes of abdominal pain, whereas acquired disorders are observed more frequently in older children and adolescents.

Diagnostic laparoscopy for contralateral patent processus vaginalis and nonpalpable testes.

Diagnostic laparoscopy can be a valuable adjunct for the surgical approach to surgical conditions in children. Two frequently employed indications for diagnostic laparoscopy in children include (1) the search for a contralateral patent processus vaginalis in a child with a known inguinal hernia and (2) localization and management in boys with a nonpalpable testis. Laparoscopy to investigate a possible contralateral patent processus vaginalis is easily performed using a 3-mm, 70 degrees telescope through the known inguinal hernia sac and requires only 5 minutes for completion. Diagnostic laparoscopy in boys with a nonpalpable testis is performed through a 5-mm cannula placed in the umbilicus and takes less than 10 minutes to accomplish. Depending on the laparoscopic findings, ligation of the testicular vessels is possible at laparoscopy in boys with an abdominal testis who appear best managed by a two-staged Fowler-Stephens operation. In addition, laparoscopic orchiectomy may be performed in teenage boys who have an atrophic testis.

Laparoscopic cholecystectomy.

Cholelithiasis has been considered infrequent in the child, but its reported incidence has increased during the past 2 decades. Several risk factors for the development of biliary calculi, including prolonged parenteral nutrition, gallbladder stasis, ileal resection, and hemolytic disease, are peculiar to children. Most gallstones in children are thought to develop from hemolytic conditions; however, the increase in gallstones seen in the past 2 decades is more likely due to an increase in nonhemolytic cholelithiasis. With the increased incidence of cholelithiasis in the pediatric patient, cholecystectomy will become a more common procedure. Laparoscopic cholecystectomy already has become the surgical technique preferred for most adults and is rapidly gaining acceptance in children. Twenty-five children have undergone laparoscopic cholecystectomy since June 1990 without intraoperative or postoperative complications. Cholangiography was possible in 16 patients. However, because of the size of the pediatric patient, essential modifications have been made in the procedure to adapt it to the infant and child.

Wherein lies the future?

The number of endoscopic procedures performed in adults has grown beyond all imaginable thoughts over the past 3 years. Likewise, the application of this technology in children is growing rapidly, and what the future holds or what limits this technology will reach is unknown. In the preceding articles, the authors have described commonly applied indications for endoscopic surgery. There are other areas in which the technique is being used but not as frequently. Moreover, there are a few indications for which there is little, if any, experience in children; however, these may become applicable in the future as additional expertise is gained.

Cologastric fistula as a complication of percutaneous endoscopic gastrostomy.

Percutaneous endoscopic gastrostomy (PEG) is frequently used for long-term enteral nutrition or gastrointestinal decompression in both adults and children. The rare complication of a cologastric fistula following PEG has been seen recently in two pediatric patients. One fistula did not close after removal of the gastrostomy tube. A mechanism for the occurrence of this complication in these two children is proposed and technical points are emphasized to prevent this complication.

Multimedia article. Laparoscopic fundoplication in an infant.

BACKGROUND: Laparoscopic fundoplication in infants and children is rapidly becoming the procedure of choice for surgical correction of symptomatic gastroesophageal reflux because of the advantages of reduced discomfort and decreased hospitalization. In addition, there may be a hidden benefit of an earlier return to work by the parents. METHODS: This video depicts the salient operative features for performing a laparoscopic fundoplication in an infant who presented with an acute life-threatening event, which was felt secondary to gastroesophageal reflux. In this operation, a 5 mm cannula was placed in the umbilicus through which insufflation was achieved and a 5 mm, 45 degrees angled telescope was inserted into the peritoneal cavity. The four instruments were placed directly through the abdominal wall using a stab incision technique rather than using cannulas. Moreover, the operation was performed using AESOP, the voice-activated telescopic holder, which provides a steady and consistent view. RESULTS: The operative technique was straightforward in that the short gastric vessels were divided, the crura were closed, and the esophagus was secured to the crura to keep the esophagus in an intraabdominal position and to prevent transmigration of the fundoplication wrap in the postoperative period. The length of the fundoplication should be around 2.0 cm and was measured to ensure that the fundoplication approximates this length. CONCLUSION: This patient made an eventful recovery and was discharged the following day. No complications have developed. [The full text of this article is a video computer file.]

Laparoscopy for the nonpalpable testis.

Between 1988 and 1992, 287 infants and children have been evaluated for an undescended testis. In 35, the testis was not palpable. These 35 patients ranged in age between 10 months and 14 years, with a mean of 44 months and a median of 15 months. Thirteen patients had a nonpalpable right testis, 18 had a nonpalpable left testis, and four had bilateral nonpalpable testes. Diagnostic laparoscopy was performed in these 35 boys with a nonpalpable testis to allow a planned approach to management of this condition. In 11 children, a testis was visualized. The testis was in an inguinal hernia sac in seven, and single stage conventional orchiopexy was performed. In four children an intra-abdominal testis was seen, and three infants underwent laparoscopic clip ligation of the testicular vessels. One teenager underwent orchiectomy. In 21 of the remaining 24 boys, small, attenuated testicular vessels were noted to pass into the inguinal canal and inguinal exploration was required. A small testicular remnant was excised in 15 patients, but orchiopexy was possible in six boys. Diagnostic laparoscopy takes 7 to 10 minutes and enables the surgeon to develop a planned approach to this condition. With the information gathered at laparoscopy, the surgeon is best able to decide if an inguinal exploration is necessary or if a single-stage orchiopexy is possible. If a two-stage orchiopexy is required for an intra-abdominal testis, then clip ligation of the testicular vessels can be performed laparoscopically as the first stage, followed by Fowler-Stephens orchiopexy 6 to 9 months later.

Twenty-five-year surgical experience with pheochromocytoma in children.

Our objective was to analyze the presentation, diagnostic localization, operative management, histology, and long-term outcome of a single center's experience with pheochromocytomas in children. A chart review was done to identify all operatively managed pheochromocytomas in patients age 18 years or younger. Open and laparoscopic cases were included. We reviewed the presentation, diagnostic imaging, localization, operative management, pathology, and postoperative outcome of these patients. Clinic visits, contact with the tumor registry, and telephone interviews were used for follow-up. From 1973 through 1999, there were 11 children (four males and seven females) with 14 pheochromocytomas. Two (18.2%) patients had bilateral adrenal lesions and one patient had both adrenal and extra-adrenal tumors. Six (54.5%) patients had extra-adrenal lesions. The average age at operation was 14.7 years (range 9-18 years). Nine (82%) patients had significant hypertension at presentation. CT was used to localize the tumor in eight patients and urine catecholamine levels were used to confirm the diagnosis. Two of the cases were associated with inherited syndromes (multiple endocrine neoplasia 2A and von Hippel-Lindau). Ten patients underwent an open operation and one patient had a laparoscopic resection. The average patient follow-up was 9.2 years (range 9 months to 25 years). There were no operative complications and all patients were alive and well at the time of last follow-up. Three patients (27.2%) had tumors with microscopic malignant features. No tumors recurred or had evidence for metastatic spread. We conclude that peak incidence of pheochromocytomas in children is in early adolescence. Resection can be carried out safely with minimal morbidity and mortality. Current best management of this entity includes establishment of a biochemical diagnosis, adequate preoperative blockade, appropriate imaging, and an individualized operative approach based on tumor location and size.

The outcome of laparoscopic Heller myotomy without antireflux procedure in patients with achalasia.

We retrospectively reviewed 30 patients with achalasia (18 males, 12 females) undergoing laparoscopic Heller myotomy without antireflux procedure to determine relief of dysphagia and prevalence of postoperative gastroesophageal reflux. Preoperative symptoms were obtained by history alone before 1996 and by standardized questionnaire after September 1996. Twenty-nine patients (97%) had dysphagia, 22 patients (73%) had regurgitation, 21 patients (70%) had weight loss, 7 patients (23%) had heartburn, and 4 patients (13%) had nocturnal aspiration. The first 3 patients were done thoracoscopically, with the subsequent 27 patients performed laparoscopically; 4 cases (13%; 1 thoracoscopic and 3 laparoscopic) were converted. The mean postoperative stay was 1.9 days (1-6 days). One patient underwent repeat laparoscopic myotomy for persistent dysphagia. Twenty-eight patients (93%) were available for follow-up. Patients were asked on a standardized questionnaire to grade their relief of dysphagia, regurgitation, and heartburn. Good to excellent relief of dysphagia was obtained in 25 patients (89%), whereas 3 patients (11%) continued to have significant dysphagia postoperatively. Twenty-four patients (86%) had little or no regurgitation. Four patients (14%) had frequent regurgitation. Twenty-four patients (89%) reported little or no heartburn. Three patients (11%) reported significant postoperative heartburn. Laparoscopic Heller esophagomyotomy without antireflux procedure provides excellent symptomatic relief of dysphagia in patients with achalasia. Early follow-up suggests that minimal occurrence of symptomatic postoperative reflux can be achieved without performing an antireflux procedure.

Survival after gastrointestinal perforation from esophageal atresia and tracheoesophageal fistula.

Management of premature infants with esophageal atresia (EA), tracheoesophageal fistula (TEF), and respiratory distress syndrome (RDS) can be one of the most challenging aspects in the surgical care of the newborn. Although not common, there have been reports of EA, TEF, and RDS with gastric perforation, but an associated duodenal perforation has not been reported. Two premature infants weighing less than 1,200 g with EA, TEF, and perforation are described. One baby developed a gastric perforation and the other a duodenal perforation. Emergency thoracotomy and fistula ligation were necessary after gastrostomy placement. These patients are the smallest infants reported to survive gastrointestinal perforation complicated by EA, TEF, and RDS.
