The anatomic basis of the transversus and rectus abdominis musculoperitoneal (TRAMP) composite flap

1999

The aim of this study was to provide an anatomic basis for the transversus and rectus abdominis musculoperitoneal (TRAMP) flap, recently successfully introduced for vulvovaginal reconstruction. In 25 cadavers the width and length of the portions of rectus and transversus abdominis muscles suitable for the TRAMP flap as well as the length and diameter of the inferior epigastric artery were assessed. The mean length of the rectus abdominis muscle was 32.42±0.48 cm and its width 6.15±0.12 cm. The suitable part of the transversus abdominis muscle measured 19.08±0.3 cm mean length with a mean width of 18.62±0.19 cm. No significant left-right differences were observed. The resulting area of the r…

Rate of Post-Operative Pancreatic Fistula after Robotic-Assisted Pancreaticoduodenectomy with Pancreato-Jejunostomy versus Pancreato-Gastrostomy: A R…

2021

Background: Different techniques of pancreatic anastomosis have been described, with inconclusive results in terms of pancreatic fistula reduction. Studies comparing robotic pancreaticogastrostomy (PG) and pancreaticojejunostomy (PJ) are scarcely reported. Methods: The present study analyzes the outcomes of two case-matched groups of patients who underwent PG (n = 20) or PJ (n = 40) after pancreaticoduodenectomy. The primary aim was to compare the rate of post-operative pancreatic fistula. Results: Operative time (375 vs. 315 min, p = 0.34), estimated blood loss (270 vs. 295 mL, p = 0.44), and rate of clinically relevant post-operative pancreatic fistula (12.5% vs. 10%, p = 0.82) were simil…

Histological effects of He-Ne laser on the healing of experimental colon anastomoses in the rat

1990

Despite technical advances, the incidence of anastomotic leaks in elective colorectal surgery remains around 14%, Recent studies suggest that the use of low energy lasers may enhance wound healing in different tissues in a selective, nondestructive manner. Based on these findings we have attempted to provide experimental background on the histological effects of He-Ne laser during the early stages of healing in 70 colonic anastornoses performed on rats, The irradiation of the anastomoses by two doses of 3.6 J/cm produces an increase in the populations of round cells and fibroblasts of the scar tissue, an increase in new vessel formation and a significant improvement in epithelialization. Th…

Urolithiasis Following Portacaval Shunt in Rats

1987

A reliable technique for a portacaval anastomosis (PCA) in rats was first published by Lee and Fisher 1961. Since then the biological and biochemical consequences have been studied extensively in numerous investigations. The occurrence of a urolithiasis following PCA was first reported by Herz et al. 1972. Disturbances of uric acid metabolism that were caused by the shunt were thought to be responsible. They should lead to an increased production of endogenous uric acid and thus to hyperuricosuria. Investigations that were published since then mainly focused on chemical stone analysis (Bichler et al. 1974; Rasenack et al. 1977; Wallace et al. 1984).

Beurteilung der Durchgängigkeit von koronaren Bypassgefäßen mit einer 2D T2-gewichteten Turbo-Spin-Echo-Sequenz (HASTE) in Atemanhaltetechnik

1999

AIM To evaluate the patency of coronary artery bypass grafts with a 2D T2-weighted breath-hold turbo-spin-echo sequence. METHODS 38 patients with 97 grafts (19 internal mammary artery and 78 saphenous vein grafts) and a total of 120 distal anastomoses were studied at 1.5 Tesla in supine position using a phased array body coil. An ECG gated 2D T2-weighted breath-hold turbo-spin-echo sequence (HASTE) was performed. Reference method was selective coronary angiography. The image material was evaluated independently by two radiologists (observer one, a radiological fellow and the second a staff radiologist). RESULTS Observer 1 reached a sensitivity of 96% (72/75) and a specificity of 91% (20/22)…

Measuring Intraoperative Oesophageal Anastomotic Tension With a Knot-Pusher–Mounted Dynamometer Is Not Quite Ready for Take-Off

A Continuous Suture Anastomosis Outperforms a Simple Interrupted Suture Anastomosis in Esophageal Elongation.

2020

Abstract Introduction Long-gap esophageal atresia represents a distinct entity among the esophageal atresia spectrum. In many patients, achieving a reasonable anastomosis depends on some millimeters of tissue. We aimed to determine what effect the suturing technique would have on esophageal ex vivo elongation as it may determine the strength of a primary anastomosis. Materials and Methods In an analysis of porcine esophagi from animals for slaughter (100–120 days old with a weight of 100–120 kg), we determined esophageal length gain of simple continuous and simple interrupted suture anastomoses subjected to linear traction until linear breaking strength was reached. Statistical power of 80%…

Development of Bladder Carcinoma Following Portacaval Shunt in Rats

1987

Portacaval anastomosis (PCA) was first introduced by Eck (1877) and was investigated in a number of different animals. Lee et al. (1961; 1974) published a reliable method with low mortality in rats. The occurrence of urolithiasis in rats following portacaval anastomosis happened to be noticed by chance. It was published by Herz et al. (1972a, 1972b, 1973), who defined the portacaval shunt rat as an experimental model. Heine et al. (1979) described dysplastic and neoplastic changes of the bladder mucosa following portacaval anastomosis. His findings were confirmed by Duy et al. (1981); Grun et al. (1982), and Dubuisson et al. (1984). However, Wallace et al. (1984) found papillary hyperplasia…
