A new technique for intestinal isoperistaltic anastomosis utilizing a linear stapler for enlargement after anastomosis performed with a circular stapler

Background The high incidence of anastomotic stenosis after gastrointestinal surgery using circular staplers is a major problem. In response, we have developed a new technique that uses a linear stapler to enlarge an anastomotic opening made using a circular stapler. Methods Anastomoses were created by the new technique or by the conventional approach using a circular stapler in pig small intestine. The method was also applied in treatment of a colon cancer patient. Results The area of the anastomotic opening obtained with the new technique was more than 3 times that in the control (p < 0.001), with no significant difference between the methods in a leak test. Follow-up of the patient undergoing surgery with this approach revealed an uneventful course with a widely patent anastomosis confirmed after 3 months. Conclusions This procedure provides a larger anastomotic opening than conventional anastomosis with circular staplers, without impairing the integrity of the anastomosis.     

Transanal treatment of strictured rectal anastomosis with a circular stapler device: simple and safe

BACKGROUND: Several methods of treatment for benign anastomotic strictures after low anterior resection have been described. We report and illustrate a simple, safe, and effective method for treating benign rectal anastomotic strictures by means of a transanal circular stapling device. METHODS: Three patients with a clinically significant rectal stricture underwent transanal resection of the fibrous stenosis by a circular stapler device (CEEA stapler 29 or 31 mm calibre; Tyco Co., USA). RESULTS: No complications occurred. Patients were discharged from the hospital on the first postoperative day. After a follow-up period of 8, 12 and 14 months respectively, no recurrence of the stricture was observed. The stool habits of all 3 patients were normal with 1-3 formed, asymptomatic fecal passages per day. CONCLUSION: Transanal reanastomosis by means of a circular stapler device is a simple and effective method. However, a larger number of patients need to be treated with this relatively new method to draw further conclusions.     

Esophago-jejunal anastomosis using an end-to-end anastomosis stapler. Clinico-radiologic study of early complications in 75 cases

Personal experience with 75 consecutive cases of terminolaterale oesophagojejunal anastomosis by EEA Stapler is reported. A total of 6 intraoperative technical problems were encountered (8%) and consisted either of incomplete suturing of the anastomosis or stapling of the jejunal wall. Postoperative radiology revealed 5 dehiscences (6.6%) and 1 stenosis (1.33%). One patient with dehiscence died (1.33%) of septic complications. One dehiscence of the afferent jejunal stump and minor pleuropulmonary complications were observed in 3 cases. After a brief review of the literature, it is concluded that oesophagojejunal anastomosis by EEA Stapler produces a low incidence of postoperative complications such as the dehiscence, stenosis or bleeding.

Cicatricial stenosis of colorectal anastomosis. Transanal treatment with circular stapler

Anastomotic strictures complicating colorectal anastomoses can be difficult to treat. This condition must not be considered as an uncommon complication. In 20% of patients it may be a serious state that may require a therapy. Two patients treated successfully without complication with the transanal use of an CEEA stapler are presented. The staple cutter is safe and easy to use, and except for a conventional anoscope, no special equipment, including fluoroscope, is needed. On the basis of the successful results obtained, the procedure using staple cutter is recommended for the treatment of anastomotic stricture of the rectum.     

Standardized technique of laparoscopic intracorporeal rectal transection and anastomosis for low anterior resection

Background Rectal transection and anastomosis at the lower rectum is the most challenging part of laparoscopic low anterior resection. Therefore, some have demonstrated that rectal transection should be performed using instruments for open surgery with small laparotomy. In our institute, however, rectal transection using a currently available endostapler followed by anastomosis with a double stapling technique is usually performed. Methods The important points of our technique are as follows: trocar placement, optimal device choice, harmonious movement between the operator and assistant for rectal transection, optimal point of piercing with the center rod of the circular stapler, and ideal positioning of the proximal colon. Results Seventy-eight patients underwent low anterior resection using this technique. There were no conversions to open surgery. All rectal transections were completed laparoscopically with an available endostapler. A diverting ileostomy was created in six cases. Anastomotic leakage occurred in only two patients (2.6%) and rectovaginal fistula in only one patient (1.3%). Conclusions Our standardized technique is considered to be safe and feasible for rectal transection and anastomosis using the double stapling technique (DST).     

Open guide suture technique for safe microvascular anastomosis

Despite the evident advances in microsurgery, anastomosis of small vessels or anastomosis of vessels having size discrepancy, remains one of the most precise and technically demanding issues in replantation surgery and free tissue transfer procedure. The patency of the vascular anastomosis is critical and essential for a successful outcome. In this study, a microvascular anastomosing technique called open guide suture technique is introduced. The technique starts with a conventional whole-layer stitch and continues under the control of a guided suture that is inserted but not completed to a knot 180 degrees distant from the initial suture. Recently, we used this technique in 30 free flap transfers and 4 replantation procedures. A total of 103 anastomoses were performed. Only 1 flap, which had both arterial and venous problems, and 1 finger replantation case that had arterial problems required revision. Both the revised cases were salvaged, giving a revision rate of 2.91% for the total number of anastomoses (3 of 103), and a 100% success rate for final flap and replanted part survival. In conclusion, this technique provides a safe anastomosis performed under completely clear visualization at each step with well-arranged knot intervals.

The 'modified triple staple' technique: a variant stapling technique for anastomosis after low anterior resection.

INTRODUCTION: Stapled techniques of coloanal anastomosis in anterior resection have gained widespread acceptance over hand anastomosis. We believe a modification of the 'triple staple technique' has ergonomic advantages over existing stapling methods and present our technique and experience here. METHODS: Fifty consecutive patients underwent anterior resection with a concomitant defunctioning ileostomy in 44 (86%) patients. A modified triple staple technique of side to end coloanal anastomosis was performed without the need of a purse string suture on the proximal and the distal segments. RESULTS: There were no major intra-operative complications. 2/50 (4%) clinical leaks and 2/37 (5.4%) radiological leaks were noted. A combined leak rate of 4/50 (8%) was reported. The incidence of anastomotic stricture encountered was 1/50 (2%). CONCLUSION: The modified triple staple technique for side to end anastomosis in anterior resection has ergonomic advantages and comparable safety to the existing techniques of stapling coloanal anastomosis. We believe this technique can be widely adopted as an added alternative to the current techniques of stapled anastomosis after anterior resection.
