RESUMO

OBJECTIVE: To outline treatment guidelines according to level of penile trauma for penile incarceration by metal devices. METHOD: A post-1950 (hand-held powered cutting tool era) Medline search was performed. Cases were divided into four groups: string techniques and variants with and without aspiration of blood from the glans; aspiration techniques; cutting devices; and surgical techniques. Trauma grade (according to Bhat et al., 1991), site time (incarceration time), removal technique, removal time, anesthesia and recovery time were assessed. RESULTS: The string technique and variants were used for grades 1-3. They had short removal (30-120 min), site (3-72 h) and recovery (1-24 h) times. Occasional glans decompressive with blood aspiration was required. Anesthesias included none (wrapping without glans aspiration), i.m. morphine and general (glans aspiration). Pure aspiration techniques used multiple needle punctures for grades 2-3. Aspiration cases had short site times (8-14 h), but required a spinal or general anesthesia. Cutting device cases (grades 1-5) required general anesthesia, had a short removal times (45-90 min), but long site (7 h-30 days) and recovery (2-66 days) times. Surgical degloving was utilized mainly for grade 5 cases, required spinal or general anesthesia, had short site (2-30 days), but long recovery (9-28 days). CONCLUSIONS: The string, wrapping, aspiration techniques and cutting devices are suited for grades 1-3. Cutting requires a shield to avoid blade trauma and water-cooling to prevent thermal injury. Suspected underlying devitalized tissue (e.g. grade 4) is examined by Wood's lamp. Failure to identify gangrenous tissue will result in post interventional complications and a prolonged recovery time.

RESUMO

Research in reduced suture fibrin glue (FG) and sutureless FG anastomosis has been lagging behind FG utilization in other surgical fields. A review of the literature for vascular, esophageal, tracheal, gastrointestinal, common bile duct, ureteral, vas deferens, and Fallopian tube FG anastomosis indicates that reduced suture FG and sutureless FG procedures may be performed with less training, reduced operating time, leakage, ischemia, inflammation, and necrosis compared to sutured techniques. Reduced suture FG vascular anastomosis augments early anastomotic strength. Suture number for esophageal, tracheal, and tracheobronchial anastomoses can be reduced with FG. Bursting strength in pig small intestine and rat colon was lower at 4 days postoperatively, but returned to sutured strength at 7 days. Mortality was unaffected, and 18-month follow-up in sutureless FG intestinal anastomosis in pigs showed no stenosis. Preliminary ureteral studies have demonstrated successful sutureless FG and reduced suture FG laparoscopic techniques in pigs. Reduced suture FG and sutureless FG vas deferens anastomosis may reduce sperm granuloma rates, with increased patency and pregnancy rates. Patency and pregnancy rates have been similar for tubal FG, reduced suture FG, autologous fibrin glue (AFG), and sutured anastomosis. Any risk of viral transmission or immune response is eliminated by AFG. While there are few studies in many areas of FG hollow vessel anastomosis, the current literature illustrates many of the advantages of FG over other anastomotic techniques and should provide impetus for continued research in this promising field of surgery.

RESUMO

INTRODUCTION AND METHODOLOGY: To develop a practical gastrointestinal sutureless anastomosis technique, 164 end-to-end and end-to-side anastomoses were performed on the small intestine (SI), large intestine (LI), rectum, esophagus and gallbladder in 109 female Landrace pigs weighing 25 kg and 35 kg. There were 116 fibrin glue (FG) and 48 sutured anastomoses. The end-to-end SI and LI anastomoses were divided into five groups: sliding absorbable intraluminal nontoxic stent (SAINT); SAINT placement device (SAINT-PD); nonsliding SAINT (nST); sutureless stapler (SS); and sutured controls. The SAINT had a sucrose base, with some having reinforcing fibers. RESULTS: No deaths from dehiscence occurred in any group except one FG-cylinder attempt in the colon (technique abandoned). Statistical analysis of gross pathology indices showed no significant group differences. However, trends favored the SAINT in many indices, including grade-0 intraluminal tissue ridge formation (70.8% SI, 84.4% LI) and grade-0 adhesion rates (45.8% SI, 73.1% LI). Histologic examination showed fewer giant cells, less inflammation, less scar tissue formation and faster healing in the SAINT and nST anastomoses than controls. Follow-up of 300-540 days demonstrated no signs of necrosis or stenosis in the SAINT anastomoses. The nST had excellent results; however, it seems impractical in SI anastomoses and unsuitable for LI. CONCLUSIONS: The SAINT-PD has potential for all gastrointestinal sites, but needs larger experimental trials. The SS technique is impractical and had high tissue ridge formation and adhesion rates. These preliminary trials suggest the simplicity, versatility and safety of the SAINT technique; however, the small groups limit result interpretation. The results present a starting point for sutureless FG gastrointestinal anastomosis, and future experimental evaluation with more extensive statistical analyses in larger studies are needed.

RESUMO

Reduced blood flow of from 43 to 71% has been reported in sutured and stapled anastomoses. The sutureless sliding, absorbable, intraluminal, nontoxic stent (SAINT)-fibrin glue anastomotic method, which clamps the stump margins between 2 dissolving surfaces, includes only two stages of temporary compression (about 6 min total using 4 IU/mL thrombin) during the glue application in order to promote vascularization. A SAINT placement device (SAINT-PD) was introduced to facilitate low rectal anastomoses. Morphohistologic results from limited trials using fibrin glue with an untied sutureless stapler technique and a prototype non-gear-driven SAINT-PD, neither having the two dissolvable clamping surfaces of the SAINT, showed a 29 and 25% incidence of intraluminal tissue ridges, respectively. Since these tissue ridges could result in subclinical dilatation or frank stenosis, and the more extensive SAINT trials had an 8% incidence of tissue ridges, redesign of the SAINT-PD was undertaken. Consequently, to improve the anastomotic quality of the SAINT-PD, the sliding absorbable reinforced ring (sucrose base) acting as the second dissolvable surface for the SAINT-PD and a new axially controlled geared SAINT-PD design are described.

RESUMO

Sutureless anastomosis of the gastrointestinal tract using fibrin glue and sliding absorbable intraluminal nontoxic stents (SAINTs) has two shortcomings, stent shaft breakage and the lack of a transanal insertion device (TID) for low anterior resection. Reinforcement of the sucrose base SAINT (R-SAINT) is described. Sutureless anastomosis is attempted using a stapleless mechanical stapler (SS) and used as preprototype to screen histologically and mechanically for TID anastomoses in the small intestine. Finally, a prototype absorbable head SAINT placement device (SAINT-PD) intended for TID, similar to the SS, is utilized on the small intestine. Fifty-seven Landrace pigs weighing 25-35 kg were used to perform 58 anastomoses, including the small intestine (15 manual, 19 SAINT, 11 SS, 5 R-SAINT, 6 SAINT-PD) and large intestine (2 R-SAINT). All anastomoses performed with the R-SAINT succeeded on the first attempt even if the shaft cracked. The SS technique proved impractical, but the histological screen results from 7 to 60 days did approximate those of corresponding SAINT anastomoses. The SAINT-PD demonstrated operational improvement over the SS, but the histological results were similar to both the SS and SAINT. The advantages of the R-SAINT and SAINT-PD are that they leave no foreign bodies or pressure clamping devices at the anastomostic site. Larger studies may show the R-SAINT and the SAINT-PD to be practical, new surgical tools in sutureless fibrin glue anastomosis.

RESUMO

The absence of foreign bodies in sutureless anastomoses provides faster healing. The first sutureless cholecystojejunostomies were reported by Murphy in 1892. The common bile duct was tied and 11 cholecystojejunostomies plus 12 jejunojejunostomies were performed in 12 Landrace pigs employing sliding absorbable intraluminal nontoxic stents (SAINTs) and fibrin glue. One cholecystojejunostomy was not performed owing to a gallbladder morphologic anomaly. Three animals died of problems unrelated to the SAINT-glue anastomoses. Of the 18 anastomoses in the 9 remaining animals, all were patent at the verification times of 14, 30, 120, and 480 days. Morphologically,there was greater edema and reduced height of the glandular epithelium in the 30-day CJs when compared to the jejunojejunal anastomoses. Results indicate that the sutureless SAINT-fibrin glue procedure is quite versatile and may be utilized for cholecystoenteric anastomoses.

RESUMO

The authors describe the case of a highly stressed 36-year-old man who experienced ten or more painful episodes per year of recurrent oral-lingual herpes simplex virus 1, which were only partially responsive to acyclovir therapy for three years. A three-year diary of activities, personal stresses, concurrent infections, local trauma, and other possible psychogenic, somatogenic, and environmental events was used systematically to attempt to pair the stresses with the recurrent herpes episodes. Chlorinated swimming pool water seems to have been the triggering agent of the recurrent herpes simplex virus 1 episodes due to its temporal correlation and the greater than twenty-four-month asymptomatic period after the patient discontinued swimming in chlorinated water, but continued to swim in fresh and salt water, along with his normal pursuit of all other activities and habits.

RESUMO

A new sutureless anastomosis technique employing a sliding absorbable intraluminal nontoxic stent (SAINT) and fibrin glue with limited (minutes) stump margin pressure is described. Fifty-one (27 small intestine, 24 colon) SAINT anastomoses were performed in 31 Landrace pigs (25-35 kg). Controls consisted of 48 (26 small intestine, 22 colon) continuous single-layer submucosal anastomoses in 26 pigs. SAINTs, which dissolve in about 30-60 min, were formed from heated sucrose and water poured into handcrafted aluminum molds. Follow-up from 7 to 540 days showed no stenosis or anastomotic imperfections in the latter part of the experiment after the SAINT production and surgical techniques were improved. The SAINT group had fewer site adhesions, faster healing, less foreign body reaction, and fewer lymphocytes than the control group. Initial results indicate that the SAINT-fibrin glue procedure may be an effective sutureless anastomotic method from the duodenum to the sigmoid colon.
