Obstetric infection control in a developing country.

In Ghana, infection has been identified as a major cause of birth-related mortality. Results of a 2-month observation of infection control practices among Ghanaian obstetric nurses and midwives indicated that most personnel did not practice basic rules of asepsis. Problems included frequent breaks in technique, inadequate sterilization and disinfection, and repeated exposure to large amounts of blood and vaginal secretions. Supplies were limited and, even when available, not always used appropriately. The situation in developing countries is different from that in the United States. Therefore, an observational needs assessment is essential to plan relevant and practical measures for change.

A standardized technique for right segmental liver resections.

HYPOTHESIS: The indications for segmental liver resections are increasing. This type of procedure can be performed by deep wedge transparenchymal transection or by the intrahepatic approach, reaching the portal pedicle through the hilar plate. We devised a systematized way to perform such an operation. DESIGN: Original surgical technique. PATIENTS AND METHODS: Fourteen consecutive patients (8 men and 6 women; mean age, 55 years) underwent right segmental liver resections between July 1, 2001, and July 31, 2002. Seven patients had liver metastasis, 3 had primary liver cancer, 3 had benign lesions, and 1 had gallbladder cancer. The surgery was performed by making 3 small incisions around the hilar plate. With a standardized method, the right posterior and anterior sheaths were reached by combining these incisions. RESULTS: Right segmental liver resection was feasible with the proposed technique in all patients. Intraoperative blood loss was minimal in all cases, and 11 patients did not require blood transfusion. There was no postoperative death. CONCLUSIONS: This operative procedure standardizes the intrahepatic approach to the right portal pedicle for right segmental resections. It may reduce bleeding at the site of hilar plate incisions and the need for main hepatic pedicle clamping and may facilitate the recognition of right posterior and anterior sheaths, with excellent immediate results.

Modified endoscopic medial maxillectomy for chronic maxillary sinusitis.

BACKGROUND: Recently, modified endoscopic medial maxillectomy (MEMM) has been described as an alternative technique to open maxillectomy for benign sinonasal neoplasms. However, few reports discuss the efficacy of MEMM for treatment of inflammatory disease of the maxillary sinus. We evaluate the efficacy of MEMM in treating chronic maxillary sinusitis. METHODS: A retrospective review of patients who underwent MEMM for refractory inflammatory disease between December 2002 and September 2004 was performed. All patients were treated with MEMM alone or as part of an endoscopic sinus surgery procedure. Standard demographic data, operative technique, and postoperative follow-up times were collected. RESULTS: Nineteen patients (average age, 57 years) underwent 24 EMMs for chronic maxillary sinusitis refractory to middle meatal antrostomy. All patients failed prior sinus surgery, including 14 Caldwell-Luc procedures. Average follow-up was 19.5 months (range, 10-27 months). One patient has persistent hyperplastic sinusitis that currently requires monthly follow-up and medical treatment. Our only complication was one nasolacrimal duct injury. CONCLUSION: MEMM is both a safe and an effective treatment for chronic maxillary sinusitis refractory to standard medical and endoscopic surgical management.

Selective sacral rhizotomy in children with high pressure neurogenic bladders: preliminary results.

Recent successful introduction of selective rhizotomy in the management of lower extremity spasticity in patients with myelodysplasia has prompted us to use it as a means of managing high pressure neurogenic bladders occasionally encountered in myelodysplastic patients. During the last 1 1/2 years 8 children have undergone selective sacral rhizotomy in an attempt to avert urinary diversion or bladder augmentation. Patient age ranged from 6.5 to 18.5 years. The level of the respective lesions was evenly distributed throughout the spine. At spinal surgery each patient had an electrode placed in the detrusor of the bladder via a suprapubic approach, electromyography electrodes were placed in the perineum and slow fill water cystometry was performed throughout the procedure. Standard electrophysiological stimulation of the nerve roots was performed to identify the rootlets that would only affect the detrusor and spare the external sphincter. Postoperative followup has been obtained on all patients. Of the patients 4 have exhibited significant improvement and they have not required augmentation, 2 have not shown any further deterioration in bladder function, 1 has demonstrated deterioration and 1 still lacks urodynamic followup. Postoperative cystometric studies have revealed a bladder capacity increase of 69% for the group. Uninhibited bladder contractions were abated in all but 1 patient. No patient has been rendered incontinent of urine from the procedure and no patient has had a problem with stool continence as a result of the rhizotomy. It appears that selective rhizotomy of the sacral roots has been able to increase bladder capacity as well as compliance in patients who normally would have been relegated to either bladder augmentation or urinary diversion. While these are encouraging results, some further followup is required to ascertain if the early improvements will be long-lasting.

Pediatric renal transplantation: anesthesia and perioperative complications.

The appropriate choice of anesthesia for patients (pts) undergoing renal transplantation (Ktx) requires minimal toxicity and accurate monitoring for pts at high risk for metabolic, cardiovascular, and respiratory perioperative complications. We evaluated the anesthetic management and postoperative follow-up in pediatric Ktx performed in the last 12 years in our institution. From 1988 to 1999, 75 ASA class II-III pts (45 males, 22 females) younger than 18 years scheduled for Ktx were studied: 49 received a graft from a cadaveric donor (CD) and 26 from a living donor (LD). All pts were treated with dialysis within 24 h before the procedure. Standard monitoring consisted of an electrocardiogram, central venous pressure, non-invasive arterial pressure, pulse oximetry, and inspiratory and expiratory gas analysis. If necessary, an arterial cannula and pediatric pulmonary catheter were introduced. Anesthesia was induced with sodium thiopental, propofol, halothane, or sevoflurane and maintained with isoflurane and/or fentanyl and droperidol in O2:N2O (FiO2 0.4%). As muscle relaxants atracurium or cisatracurium besilate were used, except in allergic pts, in whom vecuronium or rocuronium bromide was administered. Dopamine, 20% mannitol, and furosemide were used to increase diuresis. Continuous morphine and ketoralac infusions were used for postoperative pain relief. The surgical technique was the same in all cases. Complications and renal-function (RF) recovery were evaluated relating to CD and LD using the chi-square test; differences in mean anesthesia and surgical time were evaluated by Student's t-test; survival curves were calculated from the day of Ktx to death or last follow-up and estimated by the Kaplan-Meier method. Values of P below 0.05 were considered significant. Postoperative immunosuppressive therapy was based on cyclosporine together with other conventional drugs. Mean anesthesia time was 228 +/- 65 min. Mean kidney ischemia time for CD was 16.5 +/- 4 h. Four pts (3 CD, 1 LD) died within 72 h postoperatively: 3 due to cardiac failure and 1 to metabolic coma. Six pts showed cardiovascular and 3 had infective complications, all successfully treated. Three pts (2 CD, 1 LD) died within 2 to 12 months after, surgery; 10 (6 CD, 4 LD) had graft failure and are still alive on dialysis; 58 (38 CD, 20 LD) are alive in good health after a mean follow-up of 57.6 +/- 36.6 months (range 12-120 months). Fifteen of 26 pts younger than 12 years (21 CD and 5 LD) recovered RF intraoperatively (10 CD, 5 LD); 1 with CD and 1 with LD showed postoperative graft failure and 2 with CD died within 72 h postoperatively, 22 (18 CD and 4 LD) are alive in good health. This group showed no statistical difference compared to pts older than 12 years. Of 16 pts (15 CD and 1 LD) with body weight (BW) less than 25 kg, 6 showed intraoperative (5 CD, 1 LD) recovery of RF. The 3 deaths were all in CD pts, 2 within 72 h and one 2 months after surgery; only 1 LD had postoperative graft failure. Twelve pts (75%) (12 CD, 80%) are alive in good health. Compared to pts with BW of 25 kg or more, this group showed lower intraoperative recovery of RF (P < or = 0.05). No peri- and postoperative complications occurred in all 26 LD pts (100%). Recent advances in surgery, anesthesia, immunosuppression, and antimicrobial prophylaxis have made Ktx a more predictable procedure even in pediatric pts. For high-risk pts, mortality and morbidity can be controlled by accurate surgical, anesthetic, and postoperative management. Pts younger than 12 years and with BW less than 25 kg are more likely to develop peri- and postoperative complications.

Posteroinferior acromioclavicular dislocation with supraspinatus tear. A case report.

A 20-year-old man was treated for posteroinferior acromioclavicular dislocation. The diagnosis was based on standard radiographs and intraoperative findings. The distal end of the clavicle had impaled the supraspinatus muscle. Open reduction was performed 2 weeks after injury, followed by wire fixation of the acromioclavicular joint and repair of the torn superior acromioclavicular ligament and coracoclavicular ligaments. Two years after the procedure, standard radiographs revealed normal anatomic alignment of the acromioclavicular joint, with pain free range of motion. Active elevation in the scapular plane was 180 degrees, active external rotation was 80 degrees in the anatomic position, and passive internal rotation was to the T5 vertebra. The patient returned to playing baseball and tennis and was satisfied with the postoperative result.

Endoleak as a complication of endoluminal grafting of abdominal aortic aneurysms: classification, incidence, diagnosis, and management.

The inability to obtain or maintain a secure seal between a vessel wall and a transluminally implanted intra-aneurysmal graft is a complication unique to the evolving technique of endovascular aneurysm exclusion. Because the term "leak" has long been associated with aneurysm rupture, the term "endoleak" is proposed as a more definitive description of this phenomenon. Embracing both persistent blood flow into the aneurysmal sac from within or around the graft (graft related) and from patent collateral arteries (nongraft related), endoleak can be classified as primary or secondary depending on the time of occurrence (within 30 days of implantation or following apparent initial seal, respectively). Diagnostic techniques to detect endoleak include arteriography, intraprocedural pressure monitoring, contrast-enhanced computed tomography, abdominal X ray, and duplex scanning. Management strategies for endoleak range from observation with periodic imaging surveillance to correction by additional endoluminal or surgical procedures. Standardization of the terminology describing this important sequela to endovascular aneurysm exclusion should facilitate uniform reporting of clinical trial data vital to the evaluation of this emerging technique.

[The characterization of a pattern of metabolic response and energy utilization in septic surgical patients].

OBJECTIVES: To describe the energy-metabolic response pattern in septic surgical patients. Carried out in the Surgical Intensive Care Unit (SICU). Hospital Universitario. PATIENTS: Eighteen surgery patients. Inclusion criterion: sepsis according to the criteria of the American Intensive Care Society (1992). PROCEDURES: Standard invasive and metabolic hemodynamic monitoring: sequential recording of direct measuring variables and calculation of derived variables. METHOD: Monitoring of the critical illness until final discharge due to improvement or death. We included 642 hemodynamic-metabolic evaluations, codified and incorporated into a data base specially designed for the purposes. Surviving and non-surviving groups (SG and NSG) were identified. Inter-group differences were analysed using the Student or MANOVA test, and intra-group analysis was done with the ANOVA test. Significant difference p less than 0.05. MAIN RESULTS: On admission to the SICU, oxygen consumption (VO2) and carbon dioxide production (VCO2) were lower in the SG (198 mL/min vs 233 Ml/Min) and (105 mL/min vs 172 mL/min), while RQ was significantly higher (1.08 vs 0.43): the NSG showed lower arterial bicarbonate (HCO3) (11.8 mOsm/Lt vs 14.4 mOsm/Lt). At the end of monitoring, there were significant inter-group differences for RQ (0.85 vs 1.02), VO2 (346 mL/min vs 398 mL/min), VCO2 (271 mL/min vs 359 mL/min) and arterial HCO3 (18.0 mOsm/l vs 15.6 mOsm/L) when the SG was compared with the NSG. With the passage of time, in the SG, VO2 dropped progressively, the arterial HCO3 rose, and RQ rose to lipogenesis level (days 6 and 7). In the NSG, there was a late period of RQ in excess of 1.0, severe metabolic acidosis, and persistently high VO2 and VCO2. Caloric requirements were significantly higher in the NSG (1.64 kcal/min, vs 1.9 cal/min-p < 0.001). CONCLUSIONS: There were major differences between the SG and NSG energy-metabolic pattern during surgical sepsis. Initially, the SG showed serious lesion parameters with RQ characteristic of a metabolism basically of the glucose oxidation type: the VO2 was high in the NSG, with persistent metabolic acidosis, and RQ initially explained by the accumulation of ketonic bodies and, subsequently, by lipogenesis. Definition of a metabolic pattern in the septic surgery patient establishes criteria of which are unquestionably useful in prognosis, suggesting that the therapeutic program be restructured at the moment when it is noted that the patient's pattern departs from that of the survivors.

Inguinal herniorrhaphy. Reduced morbidity by service standardization.

To ascertain if service specialization and procedure standardization would improve the complication rate of inguinal herniorrhaphy, the results of all inguinal herniorrhaphies performed during a 3-year period by board-certified general surgeons who also performed a variety of other procedures common to the field of general surgery, assisted by general surgical residents (group B, 390 patients), were compared in the same institution with the results of inguinal herniorrhaphy when performed during 3 years under protocol by a Hernia Service directed by a senior faculty member assisted by junior surgical residents (group C, 442 patients). Group B patients had essentially no follow-up until they reappeared for care at the Hernia Service, whereas patients in group C achieved an 82% 7-year follow-up. The infection and recurrence rates of group C patients (0.45% and 0.9%, respectively) were significantly better than those of group B patients (5.9% and 4.6%, respectively). These results suggest that in our institution, the concentration of patients with hernias in a hernia service, manned by a specialized surgeon, produced better short- and long-term results than those obtained by general surgeons not dedicated to the field of hernia repair. Further studies will be necessary to confirm these findings.

Identification of P waves after the Cox-maze procedure: significance of right precordial leads V3R through V6R.

BACKGROUND: The maze circuit lengthens the period of atrial depolarization and may lead to small or absent P waves, which may not be readily apparent in a standard 12-lead electrocardiogram. In this prospective study, we investigate if the right precordial leads V3R through V6R can improve detection of P waves and identification of atrial electrical activity. METHODS: Standard 12-lead electrocardiograms (with leads I through III, aVR, aVL, aVF, and V1 through V6) and right precordial electrocardiograms (V3R through V6R) were recorded in 30 consecutive patients during the first 5 postoperative days and 1, 3, 6, 12, and 24 months after combined Cox-maze III procedure and mitral valve surgery. The P wave identification as an indication of atrial electrical activity and atrial contraction was proved by transesophageal echocardiographic identification of atrial contractions. RESULTS: Despite echocardiographically identifiable atrial contractions, the P waves were not visible on standard 12-lead electrocardiograms in 7 (23%) patients after 1 and 3 months, and in 4 patients after 6 months. In contrast, right precordial electrocardiograms showed P waves in all of these patients that were best seen in lead V4R. Twelve and 24 months postoperatively, only 2 patients had no visible P waves in the standard leads that were still present in the right precordial leads. However, if P waves were easily identifiable in standard 12-lead electrocardiograms (23 patients at 1 and 3 months after surgery), the right precordial leads showed P waves only in 15 patients. CONCLUSIONS: Right precordial electrocardiogram with leads V3R through V6R is a helpful tool for visualizing P waves after the Cox-maze procedure. Standard 12-lead electrocardiogram should be combined with right precordial electrocardiogram in all patients after the Cox-maze procedure.

The use of laminarias for osmotic dilation of the cervix in gynecological brachytherapy applications.

PURPOSE: Osmotic dilators (laminarias) have been used for gradual nontraumatic dilation of the cervical canal for various intrauterine procedures; however, this technique has not been well accepted in gynecological brachytherapy. The purpose of this study was to evaluate the efficacy of osmotic cervical dilation for brachytherapy in gynecologic cancer patients, without the use of general/regional anesthesia, and to assess patient tolerance, complications, and outcome. METHODS AND MATERIALS: Thirteen brachytherapy procedures were performed in 6 patients with clinical Stages I and II endometrial (5) and Stage IB cervical cancer (1), who were unable to tolerate general/regional anesthesia because of severe medical problems. An osmotic dilator (synthetic laminaria) was inserted into the cervical os 10-12 h before each brachytherapy procedure and removed just before the procedure. Standard Fletcher-Suit-Delclos tandem insertions with vaginal colpostats or cylinders were then performed. Degree of cervical dilation, patient discomfort, procedure time, intra- and postoperative complications were recorded, and local control and survival were assessed. Median follow-up was 31 months (range: 8-35 months). RESULTS: The diameter of the dilated cervical os after laminaria removal was adequate (> or = 5 mm) for tandem insertion, and no additional mechanical dilation was required in all but one procedure (1 of 13). All procedures were performed without general/regional anesthesia. The mean duration of the procedures was 44 min (range, 20-60 min). Discomfort was minimal in all cases. There were no intra- or postoperative complications. All patients maintained local control until death (1 of metastatic disease, 2 of intercurrent disease) or last follow-up (2 with no evidence of disease, 1 alive with metastatic disease). CONCLUSION: This preliminary study suggests that osmotic cervical dilation with a synthetic laminaria is a useful technique to facilitate intrauterine tandem insertion in patients who cannot tolerate general/regional anesthesia. This technique may reduce treatment-associated morbidity, shorten procedure time, and allow the delivery of adequate radiation therapy in this uncommon but challenging patient population.

Pilot study on quality assurance in cardiac surgery.

In 1986 development, testing and improvement of a multi-center based quality assurance procedure has been started by the German Society for Thoracic and Cardiovascular Surgery supplied by a research fund of the Federal Ministry of Research and Technology. Initially five cardiac surgery units took part in defining quality related items, collecting associated data and establishing a common data base. In the first year of its existence this data base received about 3800 records of patients undergoing cardiac surgery procedures using ECC. Preoperative clinical state, intraoperative actions and postoperative results including unexpected events sum up to an average record length of 300 items per procedure. Evaluation and representation of quality related data ist done in two ways: an overall quality profile consisting of 17 so called quality indicators accompanied by six patient-mix indicators enables each cardiac surgeon to get a quick global reference within the multicentrical data context, and several problem oriented profiles assist building and testing of special quality-related hypotheses towards improvement of procedure standards and performance.

Design and methods of The Collaborative Corneal Transplantation Studies. The Collaborative Corneal Transplantation Studies Research Group.

The Collaborative Corneal Transplantation Studies (CCTS) is a set of two multicenter clinical trials designed to investigate the efficacy of donor-recipient human leukocyte antigen matching and crossmatching. High-risk penetrating keratoplasty patients were enrolled through six clinical centers for either the Antigen Matching Study or the Crossmatch Study. All patients were subject to a common set of examinations, treatments, and evaluation procedures. Standard procedures for the identification of high-risk patients, administration of postoperative medications, and recognition and treatment of immunologic allograft reactions were developed and used successfully. These procedures may serve as guidelines for studies in corneal transplantation. Adoption of these methods by other investigators would facilitate evaluation and comparison of results.

Light and electron microscopic evaluation of the pectoralis major muscle following tissue expansion for breast reconstruction.

The placement of tissue expanders under the pectoralis major muscle has become a common procedure in breast reconstruction after mastectomy. Little information is available regarding the changes caused by tissue expansion on human skeletal muscle. In this study, we report the light and electron microscopic changes observed in 20 expanded pectoralis major muscles from 12 patients undergoing two-stage breast reconstruction procedures. Standard 400-cc round Radovan tissue expanders were placed, eight bilaterally and four unilaterally. Three biopsies were taken from each muscle at different locations during both the first stage (pre-expansion) and 23 weeks later at the second stage (postexpansion). The operative procedures and expansion protocol were the same in all reconstructions. No postoperative radiation therapy was added. The histologic changes were reported in a blind fashion by one pathologist. Light microscopy did not show significant pathologic changes. All but one of the pre-expansion specimens examined by electron microscope were reported as normal, whereas all of the postexpansion biopsies were grossly altered. Focal muscle fiber degeneration with glycogen deposits and mild interstitial fibrosis was noted. In addition, some fibers showed disorganization of the myofilaments in the sarcomeres. The above ultrastructural changes are significant morphologic alterations, which may be the result of muscle hypoxia. Whether these changes indicate permanent or transient transformation is yet unclear. Patient follow-up did not reveal any functional muscular deficit. We conclude that there is definite evidence to suggest significant muscular structural damage after routine subpectoral expansion for breast reconstruction.

Experience with total hip replacement at Ochsner Clinic.

Eighty-four patients had 97 total hip replacement procedures. Standard Müller components were used in the first 40 operations; the Aufranc-Turner acetabular component was used with the Müller-femoral component in the final 57 procedures. The trochanter was detached only in exceptional circumstances. Seventy-six patients with 87 replacements were followed up for 12 to 34 months. Complications, occasionally multiple, occurred in more than one third of our patients; thromboembolic disease was the most frequent. No significant wound complications occurred; there was no infection. In 71 replacements the results were excellent; in 15, good; and in 1 fair.

[Controversies in surgical treatment of gastric cancer].

Conservative surgery is performed for patients with early gastric cancer, according to the guideline proposed from Japanese Gastric Cancer Society. There are many kinds of operations, such as ordinary open surgery, laparoscopic-assisted gastrectomy, laparoscopic intragastric surgery, pyrolus preserving gastrectomy, hand-assisted laparoscopic surgery. Indications of the operations are various, but it is necessary to have standard indication for each procedure. Standard operation for advanced gastric cancer in Japan is D2 gastrectomy. Surgeons in Eastern world believed that D1 + alpha or D1 + adjuvant radio-chemotherapy are the standard treatments, because of high incidence of mortality and morbidity after D2 dissection. In Japan, D4 dissection has been performed for patients with nodal involvement, and the validity of D4 dissection is now studied by two randomized trials. Combined resection for T4 tumor is believed to be mandatory. However, the validity of pancreato-splenectomy to yield a complete clearance of No. 10 or No. 11 lymph node station is in controversial, because of high incidence of the postoperative development of pancreatic fistula, anastomotic insufficiency and abscess. There was no prospective study to confirm the effect of omentectomy. Patients with advanced gastric cancer showing a serosal invasion-diameter less than 2.5 cm have less risk of peritoneal recurrence. It may be valuable to perform randomized controlled study consisting of omentum-preserving gastrectomy and gastrectomy with omentectomy. Prognosis of patients with peritoneal dissemination was improved by intraperitoneal chomo hyporthormia and peritonectomy, and prospective studies should be done to compare the effects of systemic chemotherapy and regional chemotherapy combined with peritonectomy. Furthermore, effects of neoadjuvant chemotherapy with cytoreduction with R0 resection should be confirmed by prospective studies.
