Therapy for unhealed gastrocutaneous fistulas in rats as a model for analogous healing of persistent skin wounds and persistent gastric ulcers: stable gastric pentadecapeptide BPC 157, atropine, ranitidine, and omeprazole.

OBJECTIVE: This study focused on unhealed gastrocutaneous fistulas to resolve whether standard drugs that promote healing of gastric ulcers may simultaneously have the same effect on cutaneous wounds, and corticosteroid aggravation, and to demonstrate why peptides such as BPC 157 exhibit a greater healing effect. Therefore, with the fistulas therapy, we challenge the wound/growth factors theory of the analogous nonhealing of wounds and persistent gastric ulcers. METHODS: The healing rate of gastrocutaneous fistula in rat (2-mm-diameter stomach defect, 3-mm-diameter skin defect) validates macro/microscopically and biomechanically a direct skin wound/stomach ulcer relation, and identifies a potential therapy consisting of: (i) stable gastric pentadecapeptide BPC 157 [in drinking water (10 microg/kg) (12 ml/rat/day) or intraperitoneally (10 microg/kg, 10 ng/kg, 10 pg/kg)], (ii) atropine (10 mg/kg), ranitidine (50 mg/kg), and omeprazole (50 mg/kg), (iii) 6-alpha-methylprednisolone (1 mg/kg) [intraperitoneally, once daily, first application at 30 min following surgery; last 24 h before sacrifice (at postoperative days 1, 2, 3, 7, 14, and 21)]. RESULTS: Greater anti-ulcer potential and efficiency in wound healing compared with standard agents favor BPC 157, efficient in inflammatory bowel disease (PL-14736, Pliva), given in drinking water or intraperitoneally. Even after 6-alpha-methylprednisolone aggravation, BPC 157 promptly improves both skin and stomach mucosa healing, and closure of fistulas, with no leakage after up to 20 ml water intragastrically. Standard anti-ulcer agents, after a delay, improve firstly skin healing and then stomach mucosal healing, but not fistula leaking and bursting strength (except for atropine). CONCLUSION: We conclude that BPC 157 may resolve analogous nonhealing of wounds and persistent gastric ulcers better than standard agents.

A modified open intraperitoneal mesh (Garestin) technique for incisional ventral hernia repair.

BACKGROUND/OBJECTIVE: Incisional hernias (IHs) are a major problem following abdominal surgery. In an effort to resolve large IHs adequately, we herein present our own modified "open intraperitoneal mesh" technique, termed the Garestin technique. METHODS: We analyzed early postoperative complications (EPCs; wound infection, hematoma, and seroma) and late postoperative complications (recurrence) in 124 patients operated for IHs and recurrent IHs (RIHs) using our new technique. Our technique involved repairing hernias by preserving the hernia sac, which was later used to conceal the mesh that replaced the abdominal wall defect, thus dividing the mesh from subcutaneous tissue. RESULTS: We operated 66 patients with IH and 58 patients with RIH. In the 4-week postoperative follow-up, 29 patients had EPC; 9 of them had wound infections that healed upon antibiotic therapy, without the need for any surgical procedure. Of the 10 patients with recurrent herniation in the long-term follow-up, 6 previously had EPC. Recurrences occurred 4-25 months after the operation. CONCLUSION: Our method is reliable and safe for large ventral hernia disposal, but the final conclusion requires a larger number of patients and a longer follow-up period.
