Short-stay open appendectomy.

PURPOSE: This report describes a minimally invasive short-stay open appendectomy technique which improves the length of stay in comparison to traditional open appendectomy and improves the cost of hospitalization in comparison to laparoscopic appendectomy. STUDY DESIGN: This retrospective analysis reviewed 100 consecutive children treated with traditional open appendectomy and 100 consecutive children treated with a minimally invasive short-stay open technique with local infiltration of bupivacaine hydrochloride. Data collected for each child included age, sex, diagnosis, operative time, return to activity time, complications, length of stay, and hospital charge. RESULTS: The mean length of stay (LOS) was reduced from 2.7 days for traditional open appendectomy patients to 1.0 day for minimally invasive short-stay open appendectomy. The mean hospital charge (HC) for this short-stay open appendectomy, US dollars 6795, was significantly less than the mean HC for traditional open appendectomy (US dollars 8162), and for laparoscopic appendectomy (US dollars 7668). CONCLUSION: This short-stay open appendectomy technique offers an efficacious alternative to both traditional open appendectomy and laparoscopic appendectomy.

Intrathyroid parathyroid gland and neonatal primary hyperparathyroidism.

Neonatal hyperparathyroidism (NPHP) is exceedingly rare and often fatal. A neonate is presented with a serum calcium concentration of 33 mg/dL, an intrathyroid parathyroid gland, and a family history of hypocalciuric hypercalcemia (FHH). She underwent successful total parathyroidectomy. Six years later, the child is normocalcemic and developmentally normal, requiring calcium and calcitrol replacement. The results of this case support the concept that NPHP is associated with parathyroid hyperplasia and is part of a continuum that includes FHH.

Anterior exposure of spinal deformities and tumors: a 20-year experience.

Data from 505 patients (1976 through 1995) who underwent anterior spinal exposure were retrospectively analyzed. There were 222 boys and 283 girls with a mean age of 14.5 years; 166 had thoracic exposure (T), 300 thoracoabdominal (TA), 44 retroperitoneal (R), and 7 transperitoneal (TP); 17 had repeat exposure (5 had initial exposure elsewhere); 70% had scoliosis, 25% kyphosis, 27% a neuromuscular disorder (NMD) and 6.7% a tumor. Average intensive-care-unit stay was 2.5 days, 6.2 days for NMD (P < .05); average ileus was 3.4 days, 4.1 days for NMD (P < .05); and average length of stay was 15.4 days for all patients, 19.3 days for NMD (P < .05). Mechanical ventilation over 96 hours was required in 31 patients, 66% had an NMD (P < .05). The morbidity rate was 9.8%, 10.1% for NMD; the morbidity rate was zero for tumor and repeat exposures. Mortality was zero. Over half of the vessel injuries (57%) and the urinary tract infections (60%) occurred in NMD patients. Differences between the 1976 through 1985 period and the 1986 through 1995 period were a shorter length of stay and a majority of one-stage combined exposures in the latter period. The authors conclude that anterior exposure of spinal deformities is well tolerated by most pediatric patients, and that this technique is easily adaptable to the resection of retroperitoneal and thoracolumbar tumors.

Modified Nissen fundoplication for reduction of fundoplication failure.

Failure of the Nissen fundoplication can be secondary to disruption of the wrap or slippage of the stomach upward within the wrap. A modification of the Nissen fundoplication was devised and implemented between 1982 and 1995 to eliminate these complications. This report describes the modification and the results. Commonly, the Nissen fundoplication uses a single anterior row of sutures securing the wrapped stomach to the esophagus. This modification reinforces the wrap with two additional rows of suture, one right lateral and one left lateral, each further anchoring the wrapped stomach to the esophagus. This retrospective analysis compares the Nissen and modified Nissen fundoplications performed at our institution. Fundoplication operations were considered a failure if they required a reoperation secondary to wrap disruption or stomach slippage. Data were analyzed using the chi 2 method. A total of 948 fundoplication procedures were performed; 326 Nissen and 622 modified Nissen. Follow-up ranged from 0.5 to 13 years (mean, 6 years). Thirteen wrap disruptions and six stomach slippages occurred in the Nissen group (5.8%); 10 wrap failures and no stomach slippages occurred in the modified Nissen group (1.6%), P < .05. The authors conclude that this modification of the Nissen fundoplication significantly reduces wrap disruptions and stomach slippages.

Ileal atresia with total colonic aganglionosis.

This is the 17th report of the case of an infant who had ileal atresia associated with Hirschsprung's disease, and the second with ganglion cells distal to the atresia. Experience suggests that Hirschsprung's disease should be suspected in all forms of bowel atresia.

Familial occurrence of congenital diaphragmatic hernia : Father-to-son inheritance.

Familial occurrence of congenital diaphragmatic hernia is rare. This is only the second case of parent-to-child inheritance and the first case of father-to-son inheritance. The available data point toward a multifactorial mode of genetic transmission.

Securing central lines in rambunctious toddlers.

Central line dislodgment in toddlers continues to be a problem. The deployment of a spandex/nylon bodysuit has resulted in eliminating this problem in two overactive toddlers. We highly recommend using this type of garment in appropriate clinical situations.

A standard of comparison for acute surgical necrotizing enterocolitis.

We reviewed 187 cases of documented neonatal necrotizing enterocolitis (NEC) from 1976 to 1988. Of these patients, 111 infants underwent celiotomy for acute surgical complications. The following protocol of operative indications was employed: pneumoperitoneum, localized mass, abdominal wall erythema, portal venous air, and clinical deterioration, singly or in any combination. Clinical deterioration was defined as falling platelet count, rising or falling white blood cell count, left shift in the myeloid series, persistently or progressively low pH, and increasing frequency of apnea or bradycardia. Overall mortality was 15% (28 of 187). For the patients who underwent celiotomy, all had histologic confirmation of NEC. Ninety-five had localized disease, and 16 had diffuse disease. All of the former had resection and diverting enterostomy with 85 (89.5%) surviving; none with diffuse disease survived, P less than 0.0001. Forty-one infants with NEC weighed less than 1,000 g; 25 underwent surgery and 15 (60%) survived. Fifty-one of the 159 surviving neonates (32%) developed intestinal strictures. All neonates with strictures have had resection and successful reconstruction of their gastrointestinal tract. These indications and surgical principles resulted in a high degree of diagnostic accuracy and a low degree of surgical mortality.

Colon esophagoplasty in the orthotopic position.

Three cases of long-gap esophageal atresia were repaired using a technique that included a right extrapleural thoracotomy, preservation of the entire esophagus available, both anastomoses in the mediastinum, use of a short segment of colon, and preservation of the ileocecal valve. This approach, not previously described, combines multiple features aimed at decreasing complications related to traditional techniques. Successful early results are promising.

Complications of the Martin procedure for total colonic aganglionosis.

From 1976 to 1986 inclusive, 122 patients were cared for with Hirschsprung's disease. Sixteen of these were treated for total colonic aganglionosis, with or without small bowel involvement. The male to female ratio was 2.2:1. Two children died prior to definitive surgical therapy and two others were transferred following initial therapy. Twelve children underwent Martin's procedure with a 0% mortality rate and an 81.8% morbidity rate. This study would indicate, as do others, that even though the Martin procedure can safely be performed, the long-term results require close scrutiny. A re-evaluation of this procedure and its alternatives is necessary in order to improve long-term results.

Extensive tumor resection under deep hypothermia and circulatory arrest.

The risk of fatal hemorrhage may limit the completeness of resection in hepatic malignancies and in vascular extensions of Wilms' tumors. We have used Ein's technique of deep hypothermia (average 17 degrees C) with cardiac arrest (average 39 minutes) and exsanguination in performing five hepatic and two intravenous Wilms' tumor resections. The initial hepatic resection takes less than 15 minutes to perform in a bloodless field and the specimen is immediately examined by frozen section for determination of adequacy of margin. Additional resection is easily performed. Of four trisegmentectomies and one left lobectomy, two required additional resections. Mattress sutures were used to control hemorrhage during recirculation. One patient died from bleeding and cardiac decompensation and another from recurrence of tumor. The Wilms' tumors extended from the iliac vein into the right atrium in one child and from the right renal vein to the right atrium with extensions into the hepatic and lumbar veins in another. After nephrectomy, the atria and inferior vena cava were opened and the tumor extracted under direct vision. Both patients are well.

Occult coin perforation of the esophagus.

Only a small number of ingested foreign bodies perforate the esophagus and even a smaller fraction migrate extraluminally with no symptoms. Both of these events are even rarer after coin ingestion. Between 1972 and 1984, three children (16 months to 5 years), who had unabating upper respiratory symptoms, were found to have ingested coins. In only one child could the time interval between ingestion and appearance of symptoms (3 years) be established, and in this child the diagnosis was delayed because of failure to x-ray the chest after an ingestion episode. Surgical evaluation included chest/neck films: tracheal and esophageal shadows were separated by the object and a soft tissue mass; esphagogram: deviation of the esophagus, irregularity of the lumen, and no leak or tracheoesophageal fistula (TEF) and esophagoscopy: mucosa was intact with no direct visualization of the coin. Treatment consisted of exploration: cervical, one; thoracic, two; localization: coin in extraluminal granulomatous soft tissue; removal: without resection of the soft tissue mass or esophagus, and drainage: penrose, one; chest tube, two. There was no morbidity or mortality from 1 to 13 years later. Though generally harmless, ingested coins are capable of penetrating the esophagus. Sporadic literature reports confirm that the clinical findings and operative results are typical of this seemingly intermediate stage between perforation with mediastinitis and perforation with TEF.

Prevention of postoperative peritoneal adhesions: efficacy of povidone.

The appearance and severity of peritoneal adhesions after simple laparotomy and after adhesiolysis were studied in a rabbit model. Adhesions were induced by direct abrasion with latex glove and dry gauze; control rabbits had abrasion only. Study groups had abrasion and treatment with 10% or 25% povidone. Results showed a significant reduction in the number of adhesions and in the severity of adhesions after treatment with povidone. This study supports the further investigation of the efficacy of povidone in preventing postoperative peritoneal adhesions.

Effect of indomethacin on mesenteric circulation in mongrel dogs.

Necrotizing enterocolitis has been attributed to the use of indomethacin (INDO) for medical closure of patent ductus arteriosus. To study the effect of INDO on cardiac output and mesenteric circulation, INDO was given by rectum (0.25 mg/kg, 0.5 mg/kg, 1.25 mg/kg--3 dogs in each group) and the control group received none. The cardiac output and organ blood flow were measured before and 1 hr after INDO with radioactive microspheres using 4 isotopes (Cr53, Ni95, Co57, Sn113). The blood flow to different parts of the GI tract was measured as percent of cardiac output using a gamma counter. Paired t test was used to calculate percent reduction in organ blood flow. During the experiment, there was no reduction in cardiac output in the entire group. Anesthesia had no effect on the control group. In the three INDO treated groups, percent reduction of mucosal blood flow of the stomach (63%, 32%, 68%, p less than 0.01), mid ileum (19%, 59%, 57%, p less than 0.05) and terminal ileum (57%, 35%, 54%, p less than 0.015) was significant. A strong trend in reduction of organ blood flow was noted in other regions. There was no significant change due to different dosages of INDO. The area of ischemia in this dog model corresponds to clinical pathology noted in necrotizing enterocolitis.

The vulnerability of the vas deferens (II): the case against routine bilateral inguinal exploration.

The results of operative manipulation of the vas deferens have unknown results. In order to document early and late structural changes in the vas after simple operative manipulations, the vasa deferentia of 120 Wistar rats were subjected to 4 different manipulations. Subsequently, they were removed at intervals (up to 6 mo) and examined after appropriate staining. Finger or vascular clamp grasping resulted in mild inflammation at 6 wk, which resolved thereafter. Forceps grasping disrupted the muscle layers in 30%-40% of the vasa. Hemostat clamping damaged muscle layers in 100% of the vasa and resulted in abscess formation in 30%. Healing in forceps grasped and hemostat clamped specimens was negligible and haphazard with minimal evidence of normal collagen or elastin at 6 mo. All differences were significant (p less than 0.05). These results suggest that operative manipulations of the vas should be minimized and limited to digital maneuvers. Damage from other manipulations is appreciable, long-term, and only minimally repaired at 6 mo.
