What about sentinel node practice in early-staged cutaneous melanoma in France in 2003?

AIM: The aim of this study was to establish the status of sentinel lymph node (SLN) biopsy procedure in cutaneous melanoma in France in 2002. MATERIAL AND METHODS: This study was based upon the statistics of the main French melanoma centers. A short questionnary was sent to Head Physician by email. The authors asked for the global attitude as far as SLN was concerned, number of cutaneous melanoma diagnosed during year 2002 and of SLN procedures performed, critters of inclusion and postoperative management in each case. Abstension could be argued in a free item. Answers were sent back by email. RESULTS: The authors collected 22 answers coming from overall territory; 64% performed SLN procedure (14 centers), 36% applied "wait and watch" policy. Staffs performing SLN diagnosed a mean of 101 (8-400) melanoma and biopsied a mean of 21 (0-53) sentinel nodes. The others diagnosed a mean of 151 (15-250) melanoma. Patients were enrolled for Breslow thickness upper to 1.5 mm in 71%, to 1 mm in 29%. Ulceration was a critter of inclusion in 93% (21 staffs), 100% enrolled patients whose tumor presented signs of regression. SLN was performed for primary sites located overall body in 71%, only in limbs and trunk in 29%. Positive node lead to regional lymph node clearance, then observation or interferon protocol. Negative node lead to "wait and watch policy" in 14%, different interferon protocols according to Breslow thickness in 86%. CONCLUSION: SLN procedure is not homogenous in France. France is divided as far as SLN is concerned. If 64% are performing SLN, more than 50% of the new melanoma are not included in the trial.

Summary  

This population-based study was conducted using claims data obtained from the National Health Insurance to investigate the trend in incidence of distal radial fractures in adults in Taiwan from 2000 to 2007. Our results revealed an increasing trend, particularly among women >50 years of age.     

Dantrolenbevorratung in Anästhesie und Intensivmedizin in Deutschland

Background

A malignant hyperthermia (MH) crisis is a potentially fatal complication in anesthesia and intensive care units (ICU). Rapid administration and adequate dosage of dantrolene is the only known effective pharmacological and causal treatment of an MH crisis. International anesthesiology societies recommend an initial dose of 2.0–2.5?mg/kg body weight (BW). The necessary total dosage should be titrated up to 10?mg/kg BW depending on the effectiveness.

Objective

The goal of this study was an analysis of the stocking situation of dantrolene in Germany. A national survey was conducted amongst members of the German Society of Anaesthesia and Intensive Care (DGAI).

Material and methods

A questionnaire consisting of 19 items was posted online to all DGAI members from 2 September to 30 September 2015. The questionnaire dealt with characterization of the participants, the administration of triggering substances in the operating room and in the ICU of the respective hospitals. The main part covered the amount of stocked dantrolene, the place of storage and emergency availability of stocked dantrolene from elsewhere.

Results

The questionnaire was posted online to 12,415 DGAI members with a response rate of 13.5% (n = 1673). The highest response rate was from 259 directors and heads of anesthesiology units representing 28.3%. In total 93,7% of participants use volatile anesthetics and 82,3% use succinylcholine. In the event of an MH-crisis 40.4% of participants have 36 or more vials of dantrolene available within 5?min, 27.4% have only 24 vials and 18.7% only have 12 vials. Of the anesthesiologists in outpatient surgery 70.6% have a dantrolene stock of less than 36 vials. In those cases with insufficient dantrolene stock, 35.5% of hospitals have no agreement with neighboring hospitals. In the ICU setting, 51.8% of responding participants indicated the use of volatile anesthetics, but only 25.7% stock dantrolene in the ICU. For succinylcholine, 77.3% stated using the drug in the ICU, and 26.0% have a dantrolene stock in the ICU.

Conclusion

Almost all anesthesiologists participating in the online survey use volatile anesthethics and/or succinylcholine. Whereas almost all participants have access to dantrolene, more than half of the units have a stock of dantolene, which is less than that recommended by the DGAI. In the case of low dantrolene stock, only 61% of anesthesia departments have access to additional dantrolene within a time frame of 15min?. The results of this online survey demonstrate that the stock of dantrolene may be insufficient in some German hospitals and anesthesiology practices.

     

What education means in surgery? A surgery among chirurgical residents in university hospital in Strasbourg

OBJECTIVE: Numerous tools for surgical education are available. The objective of the study is to know how future surgeons do feel about these different possibilities to learn and what do they think about the place of e-learning, or virtual universities and on-line training and learning in their formation. METHODS: A questionnaire has been sent to each surgical student of Strasbourg University. Learning and training methods were evaluated: observation, fellowship, Internet, reading videos, reading books or scientific journals, discovery of pathology by oneself or performing surgical procedures by oneself, sharing meetings, playing pedagogic games. RESULTS: Fellowship is voted by plebiscite, as using Internet which grows the usual book contents thanks to interactivity, videos, quickenings and actuality of the inquiries. The difficulties to approach this tool is emphasized : the cost, availability, time consuming, lack of any tutor, ability with a computer. Dissection of corpses or live animals is wished by the majority of young surgeons. Using simulators or robots remains something for the future and must be evaluated. CONCLUSION: Fellowship is voted by plebiscite for learning surgery. The interest for new technologies of communication is more out of curiosity than necessity.     

Do guidelines influence results in inguinal hernia treatment? A descriptive study of 2,535 hernia repairs in one teaching hospital from 1994 to 2004

Background  The Onze Lieve Vrouwe Gasthuis (OLVG) hospital is a large district teaching hospital with a residency programme for general surgery. Since 1998, inguinal hernia (IH) repairs in this hospital were performed according to the preliminary “evidence-based guidelines” concerning IH repair. The aim of this study was to analyse whether the use of the guidelines improves the quality of IH repair measured by a reduction of the operated recurrences, especially from the patients who underwent the previous repair in this hospital. Methods  A retrospective study was performed which included all male adults (>18 years of age) undergoing IH surgery in the OLVG hospital for a primary or recurrent inguinal hernia from 1994 until 2004. Results  The use of mesh for primary hernia increased significantly from 0.6% in 1994 to 100% in 2004 (P < 0.001). The number of operations performed for recurrent IH fluctuated between 7% and almost 18%. However, the tendency towards a decrease in recurrence is clearly demonstrated by comparing the average recurrence rates of two time periods, namely, 1994–1998 (15.8%) and 2002–2004 (10.6%), proving a significant decrease (P < 0.002). The decreasing portion of recurrences previously operated in the study hospital from 64.3% (1994) to 14.3% (2004) was striking (P < 0.001). The prior operation performed before the recurrence was mesh-based in an average of 42/273 (15.4%) patients and increased each year. Conclusions  Between 1994 and 2004, a significant increase in the use of mesh-based techniques for the treatment of IH, influenced by the Dutch evidence-based guidelines, probably resulted in a significant decrease in the number of operations performed for recurrent IH.     

Ökonomie der kontralateralen laparoskopischen Leistenexploration

Background

Diagnostic laparoscopy (DL) of the contralateral side during inguinal herniotomy via the hernia sack may avoid a subsequent second operation. Can this procedure however also reduce costs in the German health care system?

Methods

Prospective analysis was performed of children operated on for inguinal hernia (IH) from March 2006 until October 2007. Using a linear mathematic model, the costs for different scenarios were calculated regarding the risk of contralateral IH. We thereby determined the incidence of contralateral IH at which DL became economically reasonable.

Results

A total of 123 unilateral IH operations (IH-OP) were performed in infants during the study period. Of these, 31 patients underwent DL of the contralateral side. Thirteen open hernia sacks were identified and ligated during the same operation. The following costs were calculated: (1) IH-OP without DL, 286 Euro, (2) IH-OP with contralateral DL, 338 Euro, (3) IH-OP with DL and synchronous ligation of the contralateral side, 393 Euro, and (4) metachronous operations of bilateral IH, 572 Euro. The incidence of contralateral hernia described in the literature ranges from 20% to 50%. Linear regression of the relative costs shows an economic advantage for DL with an incidence above 23%.

Conclusion

Laparoscopic evaluation of the contralateral side in IH-OP is a rational approach for the patient and makes economic sense in the German health care system.     

Reoperation After Recurrent Groin Hernia Repair

OBJECTIVE: To analyze reoperation rates for recurrent and primary groin hernia repair documented in the Swedish Hernia Register from 1996 to 1998, and to study variables associated with increased or decreased relative risks for reoperation after recurrent hernia. METHODS: Data were retrieved for all groin hernia repairs prospectively recorded in the Swedish Hernia register from 1996 to 1998. Actuarial analysis adjusted for patients' death was used for calculating the cumulative incidence of reoperation. Relative risk for reoperation was estimated using the Cox proportional hazards model. RESULTS: From 1996 to 1998, 17,985 groin hernia operations were recorded in the Swedish Hernia Register, 15% for recurrent hernia and 85% for primary hernia. At 24 months the risk for having had a reoperation was 4.6% after recurrent hernia repair and 1.7% after primary hernia repair. The relative risk for reoperation was significantly lower for laparoscopic methods and for anterior tension-free repair than for other techniques. Postoperative complications and direct hernia were associated with an increased relative risk for reoperation. Day-case surgery and local infiltration anesthesia were used less frequently for recurrent hernia than for primary hernia. CONCLUSIONS: Recurrent groin hernia still constitutes a significant quantitative problem for the surgical community. This study supports the use of mesh by laparoscopy or anterior tension-free repair for recurrent hernia operations.     

Incisional hernia after abdominal surgery in infants: A retrospective analysis of incidence and risk factors

PurposeIncisional hernia (IH) is a complication following abdominal surgery extensively studied in adults but less so in infants. This study aimed to identify the incidence, high risk diseases and risk factors of IH following abdominal surgery in infants.MethodsInfants undergoing abdominal surgery before the age of three years in our tertiary centre between 1998 and 2018 were included. Patient demographics, peri‑operative details and the course during follow up were retrospectively extracted from patient records. Multivariate logistic regression was performed to identify risk factors.ResultsThe incidence of incisional hernia was 5.2% (107/2055). Necrotizing enterocolitis (12%), gastroschisis (19%), and omphalocele (17%) had the highest incidences of IH. Wound infection (OR: 5.3, 95%-CI:2.9–9.5), preterm birth (OR: 4.2, 95%-CI:2.6–6.7) and history of stoma (OR 1.7, 95%-CI:1.1–2.8) were significant risk factors for IH. Whilst age at surgery, surgical approach and total number of operations did not significantly influence IH development. The IH resolved in 15% (16/107) without surgery.ConclusionOne in twenty infants experiences IH following abdominal surgery, which is higher than previously described. Understanding the incidence of IH and associated risk factors will allow physicians to identify infants that may be at increased risk for IH and to possibly act pre-emptively.     

Inguinal hernia repair in the Amsterdam region 1994–1996

In the Netherlands, approximatey 30,000 inguinal hernia repairs are performed yearly. At least 15% are for recurrence. New procedures are being introduced creating discussion on which technique is the best. Currently it is not possible to choose on evidence alone because of the long follow-up that is needed.In 1996 an inventory was taken of all inguinal hernia repairs that were performed in the Amsterdam region (9 hospitals). These results were compared with the results from a similar study performed in 1994. Major changes in treatment strategy were noted. The Bassini repair was replaced by Shouldice and Lichtenstein techniques. There was a significant increase in the use of prostheses for both primary and recurrent inguinal hernias. There was no significant decrease in the percentage of operations performed for recurrent hernia from 19.5% to 16.8%. However, there was a significant decrease in operations performed for early recurrences (5.1%–3.4%) (p=0.05). These results suggest that the Shouldice and Lichtenstein repairs may be superior to the Bassini repair in terms of early hernia recurrence.     

Virgin and Recurrent Groin Hernia: A Comparison of Patient Recovery Following Endoscopic Preperitoneal Herniorrhaphy

Introduction:

The advantage of minimally invasive hernia repair techniques remains controversial. One of the more established indications for this technique''s use is the presence of a recurrent hernia. No prior study has compared the recovery following endoscopic repair of virgin and recurrent hernias.

Patients and Methods:

Between July 15, 1994 through August 16, 1996, one primary surgeon supervised the performance of 373 hernia repairs on 250 patients. Twenty-two patients underwent endoscopic preperitoneal herniorrhaphy for unilateral recurrent groin hernia (RH), while 105 patients underwent repair of a virgin unilateral hernia (VH) in the absence of prior contralateral open hernia repair. No significant differences were seen for age (VH: 54, RH: 64), male:female ratio (VH: 92:13, RH: 22:0), operative time (VH: 58 min, RH: 59 min), anesthetic used, IV fluid requirements or blood loss (p > 0.05 for all comparisons). At the time of discharge, all patients were given a postoperative survey and asked to record their level of pain, narcotic use, and level of activity on the day of surgery and postoperative days 1, 2, 3, 7, 14, and 28.

Results:

Patients undergoing repair of virgin hernias had statistically significant increased levels of pain and/or narcotic use on the day of surgery and postoperative days 1, 2 and 3. Despite these differences, level of activity and return to work/normal activity (VH: 6.35+/- 3.44 days, RH: 6.40 +/- 2.67 days) were the same for the two groups.

Conclusion:

Despite the differences in pain perception and narcotic use in the early postoperative period, overall patient recovery appears similar for the two groups. Differences seen are likely due to a lack of any prior surgical pain to serve as a benchmark for comparison.     

Erfahrungen aus ��ber 2100 Hernienreparationen

Introduction

Inguinal hernia (IH) surgery has changed fundamentally during the last 25 years due to tension-free repair, minimally-invasive approaches and growing influence of economy in medical decision making. Aim of the study was the documentation and analysis of changes in IH surgery during the last 15 years in our patient cohort.

Material and methods

Patients undergoing elective or emergency inguinal/femoral hernia repair from January 1995 to December 2009 were included in the study. Analysis of patient data was carried out by prospective online recording.

Results

A total of 1,908 patients with 2,124 IHs were treated in the study period and the number of IH repairs decreased continuously. The number of recurrent hernias peaked in 2005?C2009 with 16.4%. The average preoperative hospital stay decreased from 2.4 to 0.4 days and the postoperative hospital stay from 7.0 to 3.3 days. The percentage of suture repairs declined from 54.9% in 1995 to 4.1% in 2009 and the percentage of open tension-free repairs rose to 52.9% in 1998. In the following years the majority of repairs were performed by minimally invasive procedures but in 2009 the percentage of conventional hernia repairs exceeded the rate of minimally invasive repairs.

Conclusion

The main reason for these changes is the implementation of diagnosis-related groups which hampers inpatient repair of ?simple?? inguinal hernias, favors short hospital stay and does not adequately reimburse minimally invasive repairs.     

The burden of incisional hernia in necrotizing pancreatitis: how can we improve?

Background

Necrotizing pancreatitis (NP) patients frequently require pancreatic debridement, and have risk factors for incisional hernia (IH). However, no published data exist regarding the incidence of IH in NP. The aim of the current study was to define the incidence of and identify risk factors for developing IH after pancreatic debridement.

Methods

Hernia presence was determined by clinical examination and patient interview. Technical and clinical considerations were noted: type of incision, closure, suture material, age, body mass index (BMI), diabetes mellitus (DM), preoperative albumin, and number of operations.

Results

Sixty-three (42%) of 149 debrided patients with NP developed IH. IH patients were older (P < .05). No differences in surgical technique or clinical risk factors were seen between groups.

Conclusion

The incidence of IH in NP patients requiring operative debridement is substantially higher than that in patients undergoing routine laparotomy. Innovative fascial closure techniques such as primary fascial buttress with nonsynthetic mesh should be considered.     

Incisional hernia repair in Germany at the crossroads: a comparison of two hospital surveys in 1995 and 2001

INTRODUCTION: Incisional hernia repair has become a controversial issue in surgery. METHODS: To survey the current practice patterns of incisional hernia repair, a questionnaire was mailed to 2 380 surgical departments in Germany. Responses were received from 732 hospitals. The results of the current survey were compared with that of a similar survey performed in 1995. RESULTS: Overall, the incidence of incisional hernia surgery seems to have markedly increased. An increasing number of operations is performed in specialized large centres. Depending on hernia type (primary hernia < 5 cm, primary hernia > 5 cm, recurrent hernia) mesh materials have gained popularity (15 %, 67 %, and 79 %, respectively) as compared to 1995. Prolene(R) (34 %) and Vypro(R) (25 %) are the currently preferred meshes. The number of hospitals that use non-resorbable suturing material has doubled between 1995 (22 %) and 2001 (45 %). Interrupted suture are no longer the standard technique for fascia closure (80 % in 1995, 50 % in 2001). Autodermal skin graft and laparoscopic hernia repair are of little importance. Although literature data suggest high recurrence rates, most surgeons still expect that only 5-10 % of their primary or recurrent hernia repairs will fail. CONCLUSIONS: Incisional hernia repair is undergoing radical changes. However, it is unclear whether these changes in surgical techniques and materials were caused by the individual surgeon's clinical expertise, the recent publication of important trials, or the financial circumstances.
