We report herein our surgical experience of Hartmann's procedure reversal using laparoscopic technique in a 72-year-old woman who underwent Hartmann's procedure for an obstructing sigmoid colon cancer 6 month earlier. The purposes of this report are to describe our technique of laparoscopic reversal of Hartmann's procedure, to introduce several technical tips in avoiding pitfalls, and to review its safty and efficacy. In brief, the colostomy was freed from the abdominal wall using a conventional technique, then a center rod and an anvil of a circular stapler were inserted into the colon. CO2 insufflation was performed through this insertion. Using a five-cannula technique, rectal stump was mobilized, then colorectal anastomosis was performed laparoscopically via a transanal stapled approach. The operating time was 130 minutes and blood loss was 50 ml. There were no intra- and postoperative complications. Up to now, with a 4-month follow-up period, the patient has been well without having any problems associated with this operation

To define the basic sequential events of the healing process in normal fracture and evaluate the role of growth regulatory molecules and extracellular matrix components, the expression of transforming growth factor β(TGF-β), platelet-derived growth factor(PDGF), type I and II collagen, and chemistry during the healing process of an experimental fracture of tibia in 41 adult rats for 7 weeks using ABC methods. The phases of inflammation, reparation, and remodeling followed each other in sequence. The inflammatory phase was characterized by hemorrhage, edema, and infiltration of inflammatory cells on the first day. During the reparative phase, the undifferentiated mesenchyme undergoes rapid chondrogenesis, followed by endochondral ossification and supplemented by appositional bone formation. At day 3, the expression of TGF-β and PDGF was noted in the undifferentiated mesenchymal cells and from day 5, these two growth factors were detected in the osteoblasts and extracellular matrix in areas of endochondral ossification and newly formed periosteal bone. From day 3, the expression of type I collagen and osteonectin was noted in the osteoblasts and extracellular matrix in both endochondral ossification and appositional bone growth as a marker of ossification. From day 3, type III collagen was mainly expressed in the plump mesenchymal cells showing chondroid differentiation and chondroid matrix as a marker of cartilaginous reparative phase. From day 14, these growth factors and extracellular matrix components were decreased in staining intensity and at the 5th week, the histology and immunostaining pattern were similar to the mature bone.

Radiofrequency catheter ablation (RFCA) has been established as an effective and safe treatment modality for atrioventricular nodal reentrant tachycardia and WPW syndrome. Surgical ablation or direct current catheter ablation had been performed to cure focal atrial tachycardia (AT), however, these treatments had limitations such as the need of open thoracotomy or the risk of barotrauma. RFCA could be an effective treatment modality for cure of AT. We performed RFCA for AT in 22 patients (male 13, mean age 38.1+/-15.4 years) among 831 patients who underwent electrophysiologic study between Jul. 1996 and May. 1999. Clinical pattern of tachycardia was paroxysmal (17 patients) or incessant (mean duration of symptoms, 41.1+/-42.3 months). Associated cardiac diseases were tachycardia-mediated cardiomyopathy (3 patients), aortic stenosis (1 patient) and ventricular septal defect with pulmonic stenosis (1 patient). AT was induced by programmed electrical stimulation in 17 patients: AT in the other 5 patients was incessant. The RFCA was successful in 17 patients (77.3%). The mean interval between atrial electrogram of mapping catheter and P wave of surface ECG was -53.5+/-24.9msec in 17 successful sites. Fractionated atrial activities were invariably found in the successful sites. Successful sites of RFCA for right AT were around coronary sinus ostium (5), crista terminalis (4), lower portion of sinus node (1), inferior portion of tricuspid annulus (1), and His area (1), respectively. In left AT, lateral portion near atrioventricular groove (2), inferoposterior portion (2) and near left atrial appendage (1) were successful site. During follow-up (mean 23 months), one patient had recurrence (recurrence rate 5.9%). RFCA for AT is an effective and curative treatment in selected cases.
