Curved cutter stapler vs. linear stapler in rectal cancer surgery: a pilot prospective randomized study.
ABSTRACT This study aimed to compare the safety and technical accessibility of linear stapler and curved cutter stapler (CCS) during mid to low rectal cancer surgery.
Between April and November 2006, 60 patients were randomly assigned to either linear staplers (DST TA; United States Surgical, Tyco Healthcare Group LP, Norwalk, CT) or the CCS (Contour Curved Cutter Stapler(R); Ethicon Endo-Surgery, Inc., Cincinnati, OH) during low anterior resection for mid to low rectal cancers.
There were no significant differences in age, gender, body mass index, and mean carcinoembryonic antigen level between the two groups. Distal resection margin was longer in the CCS group as compared with the linear stapler group but did not reach statistical significance (24.7 vs. 20.8 mm, P = 0.065). There was no difference in the incidence of postoperative complications.
In this study, both the CCS and linear staplers were satisfactory devices for securing the distal rectum during low anterior resection in mid to low rectal cancers.

ABSTRACT: This prospective study was conducted to compare the clinical outcomes of a 6-row 3-D linear cutter with the standard 4-row linear cutter in patients who underwent elective gastrointestinal surgery anastomosis. Patients who underwent elective open gastrointestinal surgery that included stapled anastomosis using a linear cutter (Proximate®, Ethicon Endo-Surgery, Cincinnati, OH) between January 2011 and May 2011 were included in the study. The patients were randomly assigned to two groups according to the linear cutter that was used in the surgery: the standard 4-row cutter (the S group) or the new 6-row cutter (the N group). The groups were compared based on the patient demographic data, the laboratory parameters, the preoperative diagnosis, the surgery performed, the operation time, intra-or postoperative complications, the time to oral tolerance and the length of the hospital stay. The S group included 11 male and nine female patients with a mean age of 65 ± 12 (35-84) years, while the N group included 13 male and eight female patients with a mean age of 62 ±11 (46-79) years (p =0.448, p = 0.443, respectively). Anastomotic line bleeding was observed in eight (40%) patients in the S group and in one (4.7%) patient in the N group (p = 0.006). Dehiscence of the anastomosis line was observed in two (10%) patients in the S group and none in the N group (p =0.131). Anastomotic leakage developed in three (15%) patients in the S group and in one (4.7%) patient in the N group (p = 0.269). The mean hospital stay was 12.65 ± 6.1 days in theS group and 9.52 ± 2.9 days in the N group (p = 0.043). The 6-row 3-D linear cutter is a safe and easily applied instrument that can be used to create anastomoses in gastrointestinal surgery. The new stapler provides some usage benefits and is also superior to the standard linear cutter with regard to anastomotic line bleeding.Clinics (São Paulo, Brazil) 09/2012; 67(9):1035-8. · 1.59 Impact Factor

ABSTRACT: One of the fundamental steps in an anatomical pulmonary resection is the main and lobar bronchus suture. Nowadays, two different types of staplers are on the market: the linear TA stapler for open surgery (Tyco Healthcare Group LP, Norwalk, CT, USA), which is based on a 'guillotine' mechanism, sewing, but not cutting the bronchus, and the endoscopic linear stapler which both cuts and sews. This study aimed to fill the void in the use of an instrument used to staple and cut at the same time in 'open' thoracic surgery, eliminating the need for a scalpel: the curved cutter stapler (Contour Curved Cutter Stapler; Ethicon Endo-Surgery, Inc., Cincinnati, OH, USA). Between May 2009 and March 2011, the Contour Curved Stapler (Ethicon) was used for the bronchus in 139 cases of non-small cell lung carcinoma (NSCLC)-29 females and 110 males ranging between 48 and 85 years (average 71.1)-and comprising 115 lobectomies (8 bilobectomies) and 24 pneumonectomies (8 on the right lung, 16 on the left lung). All patients underwent a bronchoscopic check-up 30 days after they were discharged: in all cases, the bronchial stump was clearly within normal limits. No cases of bronchopleural fistulas were observed in the 139 patients. On the basis of this study, the curved cutter stapler showed to be a satisfactory device for securing the bronchus during an anatomic resection (whether lobar or main), in 'open' thoracic surgery. However, even though there were no cases of fistula, we consider that our data is still too limited to be statistically significant.European journal of cardio-thoracic surgery: official journal of the European Association for Cardio-thoracic Surgery 12/2011; 41(3):653-6. · 2.40 Impact Factor

ABSTRACT: BACKGROUND: The use of laparoscopy to perform lower anterior rectal resection is increasing worldwide because it allows better visualisation and rectal mobilisation and also reduces postoperative pain and recovery. The Contour Curved Stapler (CCS) is a very helpful device because of its curved profile that enables better access into the pelvic cavity and allows rectal closure and section to be performed in one shot. In this paper, we present an original technique to use this device, made for open surgery, in laparoscopy and the results of our experience. METHODS: We retrospectively evaluated the data of all patients who underwent lower laparoscopic anterior rectal resection and in which the CCS was used to perform section of the rectum between September 2005 and September 2011. To perform section of the rectum a Lapdisc(®) was inserted through a 6-7 cm supra-pubic midline incision to allow placement of the CCS into the pelvic cavity. Patients' biographical and surgical data such as sex, age, indication for surgery, infection, anastomotic leakage or stenosis and staple-line bleeding were prospectively collected in a computerised database and evaluated. RESULTS: Between September 2005 and September 2011, we performed 45 laparoscopic lower rectal resection using CCS, 27 male and 18 female with a mean age of 61 years (range 40-82 years) and a mean body mass index (BMI) of 26.5 kg/m(2) (range 16.5-35 kg/m(2)). In 29 cases a temporary ileostomy was performed. Mean operative time was 131 min (range 97-210 min). In all cases it was possible to perform a lower section of the rectum with CCS. No intraoperative or postoperative staple line bleeding occurred. In two patients we observed anastomotic leaks and in one of these a temporary ileostomy was performed. None of the patients showed an anastomotic stenosis at 1-year follow-up colonoscopy. CONCLUSIONS: This study shows that CCS enables section of the lower rectum to be easily performed, especially in adverse anatomical condition, and the technique proposed by us allows the use of this stapler without giving up the benefits of laparoscopic access.The surgeon: journal of the Royal Colleges of Surgeons of Edinburgh and Ireland 11/2012; · 1.97 Impact Factor
