A new anastomat for digestive tract operations, based on the magnetic compressive technique and mechanical transmission mechanism, is composed of a removable head and a reusable body. The head includes two parts: the proximal end can be fixed to the body, and the distal end could be used for performing a purse string suture. The procedure of anastomosis is similar to that of the stapler, and the anastomoses is established using a pair of magnetic rings. The instrument makes magnamosis more simple and feasible, and it would facilitate the clinical application. The body of the anastomat is reusable and the head could be replaced according to the clinical scenarios, these could reduce the medical cost. The magnetic rings would be excreted with the feces, and there is no foreign body response at last.

OBJECTIVE: To assess the safety and efficacy of gastrointestinal anastomosis with nickel titanium shape memory alloy compression anastomosis clip. METHODS: We randomized 51 patients to undergo gastrointestinal anastomosis with stapler (n=25) and nickel titanium compression anastomosis clip (n=26) respectively. The following parameters were recorded to evaluate the safety and efficacy: mean hospitalization time, anastomotic complication, first post-operation flatus and bowel movement, and extrusion of the clip. RESULTS: Anastomotic complications such as leakage, stenosis and obstruction were not observed in both groups. There were no significant differences in the first post-operation flatus time and bowel movement time between the 2 groups (P>0.05). The clip was expelled with stool within 9-15 d. CONCLUSION Compression anastomosis clip is safe and effective.

OBJECTIVETo evaluate the safety and efficacy of a novel nickel-titanium memory alloy compression anastomosis ring(CAR27) for colorectal anastomosis.

METHODSOne sigmoid cancer patient undergone lower anterior resection(LAR) received colorectal anastomosis with CAR27 on November 12, 2009. The following parameters were recorded during 4 weeks postoperative follow-up:colorectal anastomotic complication,first post-operation flatus and bowel movement, extrusion of ring device.

RESULTSThe total operation time was 42 minutes, including 11 minutes for colorectal anastomosis. The patient had flatus at the first day and began feeding at the second day postoperatively. The ring was expelled with stool at the 10th day postoperatively. Patient didn't have anastomotic complications such as leakage or obstruction during 1 month postoperative follow-up.

CONCLUSIONThis case study primarily indicates CAR27 is safe and feasible for colorectal anastomosis.

OBJECTIVETo summarize the experience in the application of circumcision anastomat in the treatment of phimosis and redundant prepuce in children.

METHODSA total of 551 children with phimosis or redundant prepuce were treated by circumcision from 2008 to 2010, 342 with circumcision anastomat and the other 209 by traditional circumcision. Their clinical data were retrospectively analyzed.

RESULTSCompared with traditional circumcision, circumcision with the anastomat showed the advantages of less operation time (P < 0.05), fewer complications, no need for dressing, and better cosmetic appearance, but it also exhibited the disadvantages of longer healing time (P < 0.05) and more obvious postoperative pain (P < 0.05).

CONCLUSIONCircumcision with the anastomat and traditional circumcision for the treatment of phimosis and redundant prepuce in children each have their own advantages and disadvantages, but the former is more advantageous and more feasible clinically.

OBJECTIVETo evaluate the curative effect of curved cutter stapler (Contour, Ethicon Endo-Surgery, Inc) in the ultra low anterior resection for low rectal cancer.

METHODSClinic data of 56 patients with low rectal cancer from Dec. 2005 to Sep. 2006 were reviewed retrospectively. After total mesorectal excision (TME) and lateral lymph node dissection (LLD) in 56 cases, the rectal (anal) remnant was cut and closed with curved cutter stapler (Contour), and preserved for ultra low colo-rectal (anal) anastomoses with 33 mm straight intraluminal stapler.

RESULTSThere was no operational death and the mean hospitalization time was (11.2+/-3.2) days. The incidence rate of postoperative complications in 1 month was 3.57% (2/65). Both of the cases were anastomotic leakage. One was cured by surgical drainage, the other combining with rectal vaginal fistula was cured by transverse colostomy.

CONCLUSIONCurved cutter stapler has the advantages of complete cutting, safe closure and low anastomotic leakage rate in the process of ultra low anterior resection for low rectal cancer.

OBJECTIVETo compare the associated anastomotic complication of cervical esophagogastric anastomosis between stapled and hand-sewn anastomosis in minimally invasive esophagectomy(MIE).

METHODSClinical data of 203 patients with esophageal cancer receiving combined thoracoscopic and laparoscopic esophagectomy with anastomosis in the neck in our hospital from January 2010 to November 2013 were retrospectively analyzed. All the patients were divided into stapled group(104 patients) and hand-sewn group(99 patients). The incidence of anastomotic leakage and anastomotic stricture between these two groups were compared.

RESULTSThere were no significant differences between two groups in gender, age, body mass index, total protein, albumin, and neoadjuvant chemotherapy(all P>0.05). There was no significant difference between the two groups in the incidence of anastomotic leakage [6/104(5.77%) vs. 3/99(3.03%), P>0.05], while the difference in the incidence of anastomotic stricture was significant [10/104(9.62%) vs. 2/99(2.02%), P<0.05]. The time of anastomosis, dieting and hospital stay was (15.5±5.0) min, (5.0±2.8) d and (18.3±5.9) d in stapled group, which was significantly shorter than (28.0±4.5) min, (5.9±1.2) d and (21.8±4.2) d in hand-sewn group(all P<0.05).

CONCLUSIONIn the minimally invasive esophagectomy, stapled cervical esophagogastric anastomosis is simple and precise, but it is associated with increased risk of anastomotic stricture, therefore the type of anastomosis should be chosen based on the conditions of the patient.

OBJECTIVETo search for a safe and convenient surgical method for management of urethral disruption.

METHODSWe performed urethral realignment for 18 cases of posterior urethral disruption and 4 cases of ruptured bulbous urethra using the urethral guidance probe following bladder puncture stoma.

RESULTSUrethral realignment was accomplished in 21 of the cases, 18 under epidural and 3 under local anesthesia, with the mean blood loss of 20 ml and the average operation time of 18 minutes. Open surgery was necessitated in 1 case due to the complication of bladder rupture. Routine postoperative urethral dilation extended for 3 months, and all the cases were followed up for 3 to 24 months. The maximum urine flow rate was 15-22 ml/s in 13 cases and 10-14 ml/s in 7. One case received urethral anastomosis 3 months later because of urethrostenosis.

CONCLUSIONSUrethral realignment with the urethral guidance probe is a safe, convenient and effective surgical strategy for the management of urethral disruption.

This study was conducted to evaluate the mid-term results of cervical esophagogastric anastomosis using a side-to-side stapled anastomosis method for treatment of patients with malignant esophageal disease. A total of 13 patients were reviewed retrospectively from January 2001 to November 2005 who underwent total esophagectomy through a right thoracotomy, gastric tube formation through a midline laparotomy and finally a cervical esophagogastric anastomosis. Average patient age was 62.6 yr old and the male to female ratio was 11:2. The mean anastomosis time was measured to be about 32.5 min; all patients were followed for about 22.8+/-9.9 months postoperatively. There were no early or late mortalities. There were no complications of anastomosis site leakage or conduit necrosis. A mild anastomotic stricture was noted in one patient, and required two endoscopic bougination procedures at postoperative 4th month. Construction of a cervical esophagogastric anastomosis by side-to-side stapled anastomosis is relatively easy to apply and can be performed in a timely manner. Follow up outcomes are very good. We, therefore, suggest that the side-to-side stapled anastomosis could be used as a safe and effective option for cervical esophagogastric anastomosis.
