Conclusion: Growth hormone reverses the adverse effects of obstructive jaundice on small bowel anastomotic healing. it can be hypothesized that this effect is due to augmentation of insulin-like growth factors, protection of hepatocytes, enhancement of intestinal epithelization, and reversal of the resultant malnutritional state caused by growth hormone in obstructive jaundice.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Background/aims Several clinical and experimental studies have shout that obstructive jaundice delays wound healing. growth hormone may prevent delayed wound healing, since it has effects on the release of mediators in jaundice, as well as increasing the protein synthesis.
📊
Key Findings & Data:Methods: Forty male Wistar rats were allocated to four groups: Group I (n-10): intestinal anastomosis to normal small bowel, Group II (n=10): intestinal anastomosis to normal small bowel followed by growth hormone therapy (2mg/kg/day, subcutaneously), Group III (n=10): intestinal anastomosis to obstructive jaundice rat's small bowel, Group IV (n=10): intestinal anastomosis to obstructive jaundice rat's small bowel followed by growth hor-mone therapy at the same dosage The animals were observed for seven days then killed.

Abstract

Background/aims Several clinical and experimental studies have shout that obstructive jaundice delays wound healing. growth hormone may prevent delayed wound healing, since it has effects on the release of mediators in jaundice, as well as increasing the protein synthesis. Methods: Forty male Wistar rats were allocated to four groups: Group I (n-10): intestinal anastomosis to normal small bowel, Group II (n=10): intestinal anastomosis to normal small bowel followed by growth hormone therapy (2mg/kg/day, subcutaneously), Group III (n=10): intestinal anastomosis to obstructive jaundice rat's small bowel, Group IV (n=10): intestinal anastomosis to obstructive jaundice rat's small bowel followed by growth hor-mone therapy at the same dosage The animals were observed for seven days then killed. Intraabdominal adhesions, anastootic complications and anastomotic bursting pressures were recorded and tissue samples from the anastomotic site were obtained to measure hydroxyproline levels and for histopathologic examination. Results: Growth hormone had a beneficial effect on the healing of intestinal anastomosis in both jaundiced and non-jaundiced rats. This was demonstrated by clinical and mechanical parameters such as a significant increase in anastomotic bursting pressure, hydroxyproline content and histopatholagical scores. Conclusion: Growth hormone reverses the adverse effects of obstructive jaundice on small bowel anastomotic healing. it can be hypothesized that this effect is due to augmentation of insulin-like growth factors, protection of hepatocytes, enhancement of intestinal epithelization, and reversal of the resultant malnutritional state caused by growth hormone in obstructive jaundice.

Özet

Amaç: Tıkanma ikterinin yara iyileşmesi üzerine olumsuz etkisinin olduğu klinik ve deneysel çalışmalarla gösterilmiştir. Growth hormon uygulamasının yara iyileşmesi üzerine olumlu etkilerinin olduğu bilinmektedir. Ancak tıkanma ikterinde intestinal yara iyileşmesi üzerine etkisi ile ilgili bir bilgi mevcut değildir. Hem protein sentezin artırıcı etkisi hem de tıkanma ikterinde salınan mediatörler üzerine etkisinden dolayı Groıvth hormon kullanılmasının yara iyileşmesi üzerine olumlu etkisi olabileceği düşünülerek bu çalışma planlanmıştır. Yöntem: 40 erkek Wistar rat dört gruba ayrıldı: Grup I (n=10) normal ince barsağa anastomoz. Grup II (n=10) Normal ince barsağa anastomoz ve daha sonra 7 gün süreyle 2 mg/kg GH. Grup III (n=10) koledok ligasyonu ile tıkanma ikteri oluşturulmuş ratlara anastomoz. Grup IV (n-W) tıkanma sarılığı oluşturulmuş ratlara anastomoz ve 7 gün süreyle 2 mg/kg Growth hormon. Yedi gün takip sonunda hayvanlar sakrifiye edildiler. Yara enfeksiyonu, karın içi ve anastomoz bölgesi yapışıklıkları, anastomoz darlığı ve kaçakları, anastomoz patlama basınçları saptandı. Histopatolojik inceleme ve doku hidroksiprolin düzeyi için anastomoz hattından doku örnekleri alındı. Bulgular: Tıkanma sarılığının intestinal yara iyileşmesini olumsuz etkilediği ve bu etkinin grouıth hormon kullanılması ile önlenebildiği hem klinik hemde mekanik parametrelerle gösterildi. Sonuç: Growth hormon tüm vücutta anabolik etkiye sahiptir. Yara iyileşmesinin temel unsurlarından biri olan protein sentezini artırır. Ayrıca hepatositleri koruyucu etkisi yanısıra intestinal epitelizasyonu artırıcı etkisinin de yara iyileşmesinde rolü olduğu düşünülmektedir.
