Three-year follow-up analysis of the short-stitch versus long-stitch technique for elective midline abdominal closure randomized-controlled (ESTOIH) trial.

BACKGROUND: Clinical trials have shown reduced incisional hernia rates 1 year after elective median laparotomy closure using a short-stitch technique. With hernia development continuing beyond the first postoperative year, we aimed to compare incisional hernias 3 years after midline closure using short or long stitches in patients from the ESTOIH trial. METHODS: The ESTOIH trial was a prospective, multicenter, parallel-group, double-blind, randomized-controlled study of primary elective midline closure. Patients were randomized to fascia closure using a short- or long-stitch technique with a poly-4-hydroxybutyrate-based suture. A predefined 3-year follow-up analysis was performed with the radiological imaging-verified incisional hernia rate as the primary endpoint. RESULTS: The 3-year intention-to-treat follow-up cohort consisted of 414 patients (210 short-stitch and 204 long-stitch technique) for analysis. Compared with 1 year postoperatively, incisional hernias increased from 4.83% (20/414 patients) to 9.02% (36/399 patients, p = 0.0183). The difference between the treatment groups at 3 years (short vs. long stitches, 15/198 patients (7.58%) vs. 21/201 (10.45%)) was not significant (OR, 1.4233; 95% CI [0.7112-2.8485]; p = 0.31). CONCLUSION: Hernia rates increased significantly between one and 3 years postoperatively. The short-stitch technique using a poly-4-hydroxybutyrate-based suture is safe in the long term, while no significant advantage was found at 3 years postoperatively compared with the standard long-stitch technique. TRIAL REGISTRY: NCT01965249, registered on 18 October 2013.

Effects of the short-stitch technique for midline abdominal closure: short-term results from the randomised-controlled ESTOIH trial.

PURPOSE: The short-stitch technique for midline laparotomy closure has been shown to reduce hernia rates, but long stitches remain the standard of care and the effect of the short-stitch technique on short-term results is not well known. The aim of this study was to compare the two techniques, using an ultra-long-term absorbable elastic suture material. METHODS: Following elective midline laparotomy, 425 patients in 9 centres were randomised to receive wound closure using the short-stitch (USP 2-0 single thread, n = 215) or long-stitch (USP 1 double loop, n = 210) technique with a poly-4-hydroxybutyrate-based suture material (Monomax®). Here, we report short-term surgical outcomes. RESULTS: At 30 (+10) days postoperatively, 3 (1.40%) of 215 patients in the short-stitch group and 10 (4.76%) of 210 patients in the long-stitch group had developed burst abdomen [OR 0.2830 (0.0768-1.0433), p = 0.0513]. Ruptured suture, seroma and hematoma and other wound healing disorders occurred in small numbers without differences between groups. In a planned Cox proportional hazard model for burst abdomen, the short-stitch group had a significantly lower risk [HR 0.1783 (0.0379-0.6617), p = 0.0115]. CONCLUSIONS: Although this trial revealed no significant difference in short-term results between the short-stitch and long-stitch techniques for closure of midline laparotomy, a trend towards a lower rate of burst abdomen in the short-stitch group suggests a possible advantage of the short-stitch technique. TRIAL REGISTRY: NCT01965249, registered October 18, 2013.

Functional outcomes after laparoscopic versus robotic-assisted rectal resection: a systematic review and meta-analysis.

Surgical resection is crucial for curative treatment of rectal cancer. Through multidisciplinary treatment, including radiochemotherapy and total mesorectal excision, survival has improved substantially. Consequently, more patients have to deal with side effects of treatment. The most recently introduced surgical technique is robotic-assisted surgery (RAS) which seems equally effective in terms of oncological control compared to laparoscopy. However, RAS enables further advantages which maximize the precision of surgery, thus providing better functional outcomes such as sexual function or contience without compromising oncological results. This review was done according to the PRISMA and AMSTAR-II guidelines and registered with PROSPERO (CRD42018104519). The search was planned with PICO criteria and conducted on Medline, Web of Science and CENTRAL. All screening steps were performed by two independent reviewers. Inclusion criteria were original, comparative studies for laparoscopy vs. RAS for rectal cancer and reporting of functional outcomes. Quality was assessed with the Newcastle-Ottawa scale. The search retrieved 9703 hits, of which 51 studies with 24,319 patients were included. There was a lower rate of urinary retention (non-RCTs: Odds ratio (OR) [95% Confidence Interval (CI)] 0.65 [0.46, 0.92]; RCTs: OR[CI] 1.29[0.08, 21.47]), ileus (non-RCTs: OR[CI] 0.86[0.75, 0.98]; RCTs: OR[CI] 0.80[0.33, 1.93]), less urinary symptoms (non-RCTs mean difference (MD) [CI] - 0.60 [- 1.17, - 0.03]; RCTs: - 1.37 [- 4.18, 1.44]), and higher quality of life for RAS (only non-RCTs: MD[CI]: 2.99 [2.02, 3.95]). No significant differences were found for sexual function (non-RCTs: standardized MD[CI]: 0.46[- 0.13, 1.04]; RCTs: SMD[CI]: 0.09[- 0.14, 0.31]). The current meta-analysis suggests potential benefits for RAS over laparoscopy in terms of functional outcomes after rectal cancer resection. The current evidence is limited due to non-randomized controlled trials and reporting of functional outcomes as secondary endpoints.

ESTES guidelines: acute mesenteric ischaemia.

PURPOSE: Acute mesenteric ischaemia (AMI) accounts for about 1:1000 acute hospital admissions. Untreated, AMI will cause mesenteric infarction, intestinal necrosis, an overwhelming inflammatory response and death. Early intervention can halt and reverse this process leading to a full recovery, but the diagnosis of AMI is difficult and failure to recognize AMI before intestinal necrosis has developed is responsible for the high mortality of the disease. Early diagnosis and prompt treatment are the goals of modern therapy, but there are no randomized controlled trials to guide treatment and the published literature contains a high ratio of reviews to original data. Much of that data comes from case reports and often small, retrospective series with no clearly defined treatment criteria. METHODS: A study group of the European Society for Trauma and Emergency Surgery (ESTES) was formed in 2013 with the aim of developing guidelines for the management of AMI. A comprehensive literature search was performed using the Medical Subject Heading (MeSH) thesaurus keywords "mesenteric ischaemia", "bowel ischaemia" and "bowel infarction". The bibliographies of relevant articles were screened for additional publications. After an initial systematic review of the literature by the whole group, a steering group formulated questions using a modified Delphi process. The evidence was then reviewed to answer these questions, and recommendations formulated and agreed by the whole group. RESULTS: The resultant recommendations are presented in this paper. CONCLUSIONS: The aim of these guidelines is to provide recommendations for practice that will lead to improved outcomes for patients.

Prevention and treatment of bile duct injuries during laparoscopic cholecystectomy: the clinical practice guidelines of the European Association for Endoscopic Surgery (EAES).

BACKGROUND: Laparoscopic cholecystectomy is one of the most common surgical procedures in Europe (and the world) and has become the standard procedure for the management of symptomatic cholelithiasis or acute cholecystitis in patients without specific contraindications. Bile duct injuries (BDI) are rare but serious complications that can occur during a laparoscopic cholecystectomy. Prevention and management of BDI has given rise to a host of publications but very few recommendations, especially in Europe. METHODS: A systematic research of the literature was performed. An international expert panel was invited to appraise the current literature and to develop evidence-based recommendations. Statements and recommendations were drafted after a consensus development conference in May 2011, followed by presentation and discussion at the annual congress of the EAES held in Torino in June 2011. Finally, full guidelines were consented and adopted by the expert panel via e-mail and web conference. RESULTS: A total of 1,765 publications were identified through the systematic literature search and additional submission by panellists; 671 publications were selected as potentially relevant. Only 46 publications fulfilled minimal methodological criteria to support Clinical Practice Guidelines recommendations. Because the level of evidence was low for most of the studies, most statements or recommendations had to be based on consensus of opinion among the panel members. A total of 15 statements and recommendations were developed covering the following topics: classification of injuries, epidemiology, prevention, diagnosis, and management of BDI. CONCLUSIONS: Because BDI is a rare event, it is difficult to generate evidence for prevention, diagnosis, or the management of BDI from clinical studies. Nevertheless, the panel has formulated recommendations. Due to the currently limited evidence, a European registry should be considered to collect and analyze more valid data on BDI upon which recommendations can be based.

The esophageal hiatus: what is the normal size?

BACKGROUND: A hiatal hernia is defined as the protrusion of intra-abdominal organs through a dilated esophageal hiatus. The esophageal hiatus and its function have been described extensively, but an exact anatomical determination of its normal size is lacking. It seems important to define the normal size, as crural closure is an important part of surgical treatment of gastroesophageal reflux disease (GERD) and hiatal or paraesophageal hernias. The aim of this study was to determine normal values for the size of the esophageal hiatus. METHODS: In a prospective study 50 consecutive cadaver autopsies were performed between February and May 2008. The subjects had died from several diseases not related to GERD. Size of the esophageal hiatus was measured after opening the abdominal cavity before extirpation of any organs. Distance of the cardia and gastroesophageal junction and position of the angle of His were further measured. A formula was used to calculate the hiatal surface area (HSA). Results were analyzed regarding subject height, weight, body mass index (BMI), and chest circumference. RESULTS: In all 50 cadavers (24 male/26 female) the autopsy was performed and all measurements were obtained. Mean age was 74 years (40-90 years), mean height was 1.68 m (1.39-1.83 m), mean weight was 71 kg (40-120 kg), and mean body mass index (BMI) was 25 kg/m(2) (14-40 kg/m(2)). Mean chest circumference was 101 cm (75-178 range). Mean HSA was 5.84 cm(2) (3.62-9.56 cm(2)). In all cadavers the gastroesophageal junction was intraabdominal, the mean distance to the angle of His was 3.6 cm (2.7-4.6 cm), the mean length of the right and left crura was similar at 3.6 cm (2.7-4.6 cm), and the opening segment had a mean length of 2.4 cm (1.7-4.0 cm). CONCLUSION: The mean HSA was determined in these normal subjects to be 5.84 cm(2). It was directly proportional to chest circumference and independent of height, weight, BMI, and gender.

Results of a new method to stop acute bleeding from esophageal varices: implantation of a self-expanding stent.

BACKGROUND: Acute bleeding from nontreated esophageal varices is associated with a mortality rate of 30% to 50%. Various pharmacologic and interventional methods to stop acute bleeding are available. However, for 10% to 20% of patients, therapy fails to stop the bleeding. This study aimed to assess the SX-ELLA Stent Danis Set (which has a self-expanding metal stent) instead of a balloon probe for compression of esophageal varices. METHODS: Using a multidisciplinary approach, a self-expanding stent was placed in 39 patients between January 2003 and August 2007. For 34 of these patients with ongoing bleeding from esophageal varices, stent implantation was performed with the SX-ELLA Stent Danis Set, and the patients were included in this study. For all these patients, common methods failed to stop hemorrhage. With the SX-ELLA Stent Danis Set, the stent was implanted with a positioning balloon that enabled delivery without X-ray control. After implantation of the stent, its position was controlled by endoscopy and computed tomography (CT) scan. RESULTS: For all 34 patients, the implantation of the esophageal stent succeeded in stopping ongoing bleeding. No stent-related complications occurred during or after stent implantation. No bleeding recurrence was observed during the stent implantation (median time, 5 days; range 1-14 days). For all the patients, the stent could be extracted by endoscopy without any complications using an extractor. Nine patients died of hepatic failure within 30 days after the procedure. No rebleeding occurred. CONCLUSIONS: The use of a self-expanding stent to stop acute bleeding from esophageal varices is a new therapeutic method. The authors' initial experience, which involved no method-related mortality or complications, is encouraging. More data are necessary to confirm their results.

Effect of hyaluron derivate gel in prevention of postsurgical peritoneal adhesions--an experimental study in pigs.

BACKGROUND/AIMS: The aim of this study was to assess the efficacy of a hyaluronic acid derivate gel in reducing adhesions in pigs undergoing laparoscopic abdominal cavity surgery. METHODOLOGY: 20 domestic female pigs underwent laparoscopy in general anesthesia. 4 defined serosal defects have been made (hepatoduodenal ligament, parietal, anterior stomach wall and jejunal mesentery). The defects have been covered with 20 mL Hyalobarrier Gel in 10 randomly selected pigs. 2 weeks postoperatively the pigs got reoperated for evaluation of potential adhesions. RESULTS: 17 pigs remained for evaluation. 2 pigs died during introduction of anesthesia, one at the end of the operation. None of the pigs died due to a reaction to the gel. We found adhesions in 33% of the gel group (n=3 out of 9) and in 87.5% in the group without gel (7 out of 8): p < 0.05. Most of the adhesions have been found at the parietal defect (7 out of 17 at all). CONCLUSIONS: The hyaluronic acid gel was highly efficacious and reduced the number and extent of adhesions throughout the abdomen following laparoscopic peritoneal surgery significantly.

Screen height as an ergonomic factor in laparoscopic surgery.

BACKGROUND: The increasing number of routinely performed laparoscopic operations causes the surgeons' "screen work" time to rise constantly. A new ergonomic workload on the surgeons' upper spine and shoulders is created as a result of the standard screen height position on top of the laparoscopy towers. METHODS: Eight surgeons in the authors' surgical department were evaluated for the inclination/reclination angle of their cervical spine when using the laparoscopy towers in the authors' department and also at their favorable screen height. RESULTS: The laparoscopy towers used in the authors' department made 3 degrees to 14 degrees reclination of the cervical spine necessary. The interviewed surgeons preferred a position of slight inclination, with a median of 160 cm measured from the central screen height to the floor. CONCLUSION: Monitors of laparoscopy towers should be adapted to the surgeon's preferred screen height: at eye level frontally with a neutral or slight inclination of the cervical spine. The authors suggest a central screen height of 160 cm, with the monitor positioned in front of the surgeon. Newer equipment from the industry should be provided.

Laparoscopic azygoportal disconnection procedure with a bipolar feedback controlled sealing system in a porcine model.

BACKGROUND: To examine the feasibility of a new, minimally invasive procedure for the devascularization of the proximal stomach and distal esophagus to prevent recurrent variceal bleeding in portal hypertension in a new animal model. MATERIAL AND METHODS: Portal hypertension was created by laparoscopic clip ligation of the portal vein on 20 pigs. After 2 weeks the azygoportal disconnection procedure was performed with the LigaSure-ATLAS instrument. RESULTS: There were 16 pigs out of 20 that survived both operations. Two died during introduction of anesthesia, one because of a cardiac arrest (second operation). One pig died resulting from necrosis of the gastric and esophageal wall. Autopsy (2 weeks later) showed that there was a complete arterial devascularization. At autopsy, none of the remaining 16 pigs had esophageal varices or necrosis of the stomach or esophagus. CONCLUSION: Laparoscopic azygoportal disconnection is a less invasive method for the prevention of rebleeding and seems to be safely performed with the LigaSure-ATLAS instrument.

Short- versus long-sequence MRI cholangiography for the preoperative imaging of the common bile duct in patients with cholecystolithiasis.

BACKGROUND: This study aimed to compare an 18-s fast spin echo magnetic resonance image sequence (coronal thick-section two-dimensional breathhold) with a three-dimensional axial and coronal thin-section sequence and its secondary reconstruction, and to assess its value in the diagnosis of bile duct pathologies, particularly common bile duct stones (CBDS) before laparoscopic cholecystectomy. METHODS: This study prospectively included 72 patients. Because of protocol violations, 14 of these patients had to be excluded. Thus, 58 patients (29 Man and 29 women with a mean age of 51 years) who had cholecystolithiasis or suspected choledocholithiasis were evaluated. Magnetic resonance cholangiopancreatography (MRCP) was performed for all patients with a fast sequence (18 s) and a long sequence (coronal oblique and axial respiratory triggered; 16 min). Two radiologists, blinded with respect to diagnosis, evaluated all the radiographic images. The MRCP results were confirmed for all the patients: 20 by endoscopic retrograde cholangiopancreatography, 46 by intraoperative cholangiography, and 2 by percutaneous transhepatic cholangiography. RESULTS: According to the findings, 16 patients (28%) had CBDS, 6 patients (10%) had common bile duct stenosis, and 36 patients (62%) had a clear bile duct. With regard to CBDS, the short sequence had 100% specificity, 94% sensitivity, and an overall accuracy of 98%. Its negative predictive value was 98%, and its positive predictive value was 100%. The long sequence had a specificity of 100% and a sensitivity of 100%. CONCLUSION: Because of its high sensitivity and specifity, MRCP has the potential to be the diagnostic method of choice for CBD evaluation. The short sequence is not suitable for the diagnosis of all CBD pathologies, but in cases of suspected CBDS, more than 80% of the patients could be diagnosed correctly, and the complete sequence could be dropped.

Closure of the cystic duct during laparoscopic cholecystectomy with a new feedback-controlled bipolar sealing system in case of biliary obstruction--an experimental study in pigs.

BACKGROUND/AIMS: The excellent results of new devices like the new bipolar feedback-controlled sealing system (LigaSure) for closure of blood vessels encouraged surgeons to use these instruments for other structures like bile ducts. The aim of this study was to evaluate the feasibility of closure of cystic duct in case of biliary obstruction. METHODOLOGY: Ten domestic pigs underwent laparoscopic cholecystectomy sealing the cystic duct with LigaSure. The common bile duct was closed with an endoclip to create a biliary hypertension. On the 12th postoperative day blood samples were taken for liver enzymes. At autopsy on day 15 the pigs were investigated for bile leaks or biliary peritonitis. The cystic duct was resected for histological examination. RESULTS: Seven pigs survived, one pig died during introduction of anesthesia, one on the 1st and one on the 2nd postoperative day without any findings at the autopsy. One pig out of 7 had a bile leak; the other 6 were without any sign of leakage. Histologically 3 pigs had a regular coagulation zone at the cystic duct, 3 had a total necrosis, one a partial necrosis of the mucosa only. CONCLUSIONS: Though there was only one insufficiency, the feedback-controlled bipolar vessel sealer cannot be recommended for biliary surgery with regard to the high rate of necrosis stated in our experiment.

Laparoscopic cholecystectomy: early and late complications and their treatment.

UNLABELLED: Laparoscopic cholecystectomy gained wide acceptance as treatment of choice for gallstone disease and cholecystitis. With this new technique, not only did the new era of minimal invasive surgery begin, but also the spectrum of complications changed. Laparoscopy-related complications such as access injuries and procedure-related problems are discussed in our article. Typical mishaps are reviewed according to the literature. Set-up of the pneumoperitoneum (morbidity up to 0.2%); bleeding-from trocar sites and vascular injury (mortality up to 0.2%); biliary leaks and bile duct injuries are the main topics in this article (still on a level of 0.2%-0.8%). Aetiology, diagnosis and treatment are discussed, and an overview of the most cited classifications of bile duct injuries is summarised graphically. Finally, bowel injuries as a specific complication in laparoscopy are discussed (incidence up to 0.87%). CONCLUSION: Careful selection of patients, the knowledge of typical procedure-related complications, and their best treatment are the key points for a safe laparosopic cholecystectomy.

Evaluation of quality of life after laparoscopic surgery: evidence-based guidelines of the European Association for Endoscopic Surgery.

BACKGROUND: Measuring health-related quality of life (QoL) after surgery is essential for decision making by patients, surgeons, and payers. The aim of this consensus conference was twofold. First, it was to determine for which diseases endoscopic surgery results in better postoperative QoL than open surgery. Second, it was to recommend QoL instruments for clinical research. METHODS: An expert panel selected 12 conditions in which QoL and endoscopic surgery are important. For each condition, studies comparing endoscopic and open surgery in terms of QoL were identified. The expert panel reached consensus on the relative benefits of endoscopic surgery and recommended generic and disease-specific QoL instruments for use in clinical research. RESULTS: Randomized trials indicate that QoL improves earlier after endoscopic than open surgery for gastroesophageal reflux disease (GERD), cholecystolithiasis, colorectal cancer, inguinal hernia, obesity (gastric bypass), and uterine disorders that require hysterectomy. For spleen, prostate, malignant kidney, benign colorectal, and benign non-GERD esophageal diseases, evidence from nonrandomized trials supports the use of laparoscopic surgery. However, many studies failed to collect long-term results, used nonvalidated questionnaires, or measured QoL components only incompletely. The following QoL instruments can be recommended: for benign esophageal and gallbladder disease, the GIQLI or the QOLRAD together with SF-36 or the PGWB; for obesity surgery, the IWQOL-Lite with the SF-36; for colorectal cancer, the FACT-C or the EORTC QLQ-C30/CR38; for inguinal and renal surgery, the VAS for pain with the SF-36 (or the EORTC QLQ-C30 in case of malignancy); and after hysterectomy, the SF-36 together with an evaluation of urinary and sexual function. CONCLUSIONS: Laparoscopic surgery provides better postoperative QoL in many clinical situations. Researchers would improve the quality of future studies by using validated QoL instruments such as those recommended here.

Novel technique of laparoscopic azygoportal disconnection for treatment of esophageal varicosis: preliminary experience with five patients.

BACKGROUND: Liver cirrhosis leads frequently to the development of ascites and a formation of varicose veins in the esophagus. The latter presents increased mortality risk. Recently, significant progress in laparoscopic technology enabled devascularization of the proximal stomach in a less invasive way. The results experienced by five patients are presented. METHODS: Laparoscopic azygoportal disconnection was performed by means of novel technique (Danis procedure) in five men with esophagus varices bleeding (2nd to 11th events) and liver cirrhosis stage Child-Pugh B and C. This procedure was performed after all other methods had either failed to prevent recurrent bleeding or were refused by the patient. Five ports were positioned on the upper abdominal wall. The veins in the lesser omentum were divided by means of the LigaSure-Atlas device. The stomach coronary vein was visualized, and all the proximal branches toward the esophagus as well as the short gastric vessels were divided. The diaphragm hiatus was opened, and the distal esophagus was dissected. The paraesophageal venous collaterals also were divided, and the remaining varicose veins of the esophagus were interrupted by transmural stitching. RESULTS: All the patients survived the minimally invasive procedure. Two of them died 9 and 16 months after surgery, respectively, because of liver insufficiency. No bleeding event from varicose veins in the esophagus occurred postoperatively. CONCLUSION: Laparoscopic azygoportal disconnection is a less invasive method for prevention of rebleeding from varicose veins in the esophagus. Further studies are necessary to confirm these preliminary results.

[Subacute thyroiditis with cell destruction and temporary hyperthyroidism in Graves'disease--case report]. / Subakute Thyreoiditis mit Zellzerfall und passagerer Hyperthyreose in einer Basedow-Struma--Fallbericht.

We present the case of a 60-year old woman with painful swelling of the thyroid gland and temporary thyrotoxicosis. 30 years ago she had experienced a period of hyperthyroidism because of Graves' disease. This time thyrotropin-receptor-antibodies were negative, Tc-99 m scan revealed decreased uptake in both lobes (this pattern normalised later on) and fine needle aspiration presented leucocyte infiltration of the thyroid. Three months later hypothyroidism was observed requiring treatment with levothyroxine. The development of subacute thyroiditis and Graves' disease in the same person is rare, autoimmune factors and a possible relationship are discussed.

A new bipolar feedback-controlled sealing system for closure of the cystic duct and artery.

BACKGROUND: Bile leaks are serious complications after laparoscopic cholecystectomy. The aim of this study was to evaluate the feasibility of closure of the cystic duct with a new feedback-controlled bipolar sealing system (LigaSure). METHODS: Ten domestic pigs underwent open cholecystectomy with the cystic duct and artery dissected and sealed with the new bipolar sealing system (LigaSure). Four and 8 days postoperatively, 5 pigs each were sacrificed and the closure of the cystic duct was evaluated. The cystic stump and the common bile duct were excised for histological examination. RESULTS: None of the pigs had a bile leak or a biliary peritonitis. There were no signs of postoperative bleeding or inflammation in Calot's triangle. Histology showed total necrosis of the cystic duct in the first two pigs due to too much energy used. The remaining specimens showed a regularly scaling zone without necrosis in 7 cases, and in one case a partial necrosis in the mucosa only was found. CONCLUSION: Cystic artery and cystic duct closure with the new device may be an alternative to the clip. Further trials should evaluate the feasibility and safety of the new device in the clinical setting.

Prospective randomized blind controlled trial comparing sutures, tape, and octylcyanoacrylate tissue adhesive for skin closure after phlebectomy.

BACKGROUND: The patient's view of the outcome after phlebectomy is mainly dependent on the cosmetic result. OBJECTIVE: To compare 5-0 monofilament sutures with tapes and tissue adhesive for wound closure after varicose vein surgery. METHODS: Seventy-nine patients undergoing varicose vein surgery were prospectively randomized in three groups (tissue adhesive, sutures, tape) for skin closure and compared. The follow-up 1 year postoperatively was done by a senior dermatologist who was blinded in the method of skin closure. RESULTS: The cosmetic outcome showed little advantage for the suture group. Taping the incisions is faster than suturing them but without significance; closure with tissue adhesive takes nearly the double of time. The closure for one incision with tissue adhesive is 40 times more expensive than with tapes and 14 times more expensive than with sutures. CONCLUSION: This study failed to demonstrate an advantage of tissue adhesive and tapes over monofilament sutures for skin closure after phlebectomy.

Follow-up of sentinel node negative breast cancer patients without axillary lymph node dissection.

BACKGROUND AND OBJECTIVES: The purpose of this study was to evaluate the feasibility of sentinel lymph node biopsy in breast cancer patients at our institution and to report the follow-up status of node-negative patients with removal of only the sentinel node. METHODS: A total of 247 breast cancer patients underwent sentinel node (SN) mapping between June of 1996 and September of 2000. The SN was identified by using a combination of vital blue dye and a radiolabeled colloid. RESULTS: A SN was identified in 227 of 247 patients (91.9%). One hundred forty-five were SN negative, 82 were SN positive. All SN-positive patients underwent axillary dissection of level I and II, whereas 83 patients with a negative SN had SN biopsy only. Median follow-up of these patients at 22 months revealed no axillary recurrence; the morbidity resulting from SN biopsy was negligible. CONCLUSIONS: Although the follow-up is very short, SN biopsy only in node-negative breast cancer patients had no negative impact on the axillary failure rate and resulted in negligible morbidity.

Sentinel lymph-node biopsy compared to axillary lymph-node dissection for axillary staging in breast cancer patients.

AIMS: The purpose of this study was to evaluate the feasibility of sentinel lymph-node biopsy in breast cancer patients at our institution and to compare the results of sentinel node (SN) biopsy to standard axillary lymph-node dissection (ALND). METHODS: In a retrospective study the percentage of lymph-node positive patients and the number of micrometastases in 165 breast cancer patients following SN biopsy was compared to 195 patients who underwent ALND of level I and II without SN biopsy. The SN was identified using a combination of vital blue dye and a radiolabelled colloid. RESULTS: Patients and tumour characteristics were comparable between both groups. SN biopsy found no significant difference in the number of node positive T1 cancer patients (SN group: 31/108 (28.7%) -- ALND group: 21/92 (22.8%)) and T2 tumours (SN group: 27/57 (47.4%) -- ALND group: 49/103 (47.6%)) between both groups. Micrometastases were more frequently found in the SN group when compared to the ALND group (six of 70 positive nodes) (P=0.04). CONCLUSION: SN biopsy may be as accurate as standard axillary lymph-node dissection for the evaluation of the axillary lymph-node status in breast cancer patients.
