Hand-sewn gastrojejunostomy using knotless unidirectional barbed absorbable suture during laparoscopic gastric bypass

Background

This report describes the authors’ institutional experience using knotless unidirectional barbed absorbable suture to close the common enterotomy of the jejunojejunostomy (JJ) and to create a hand-sewn gastrojejunostomy (GJ) during laparoscopic Roux-en-Y gastric bypass.

Methods

A retrospective review of morbidly obese patients who underwent laparoscopic gastric bypass with a hand-sewn GJ between April 2011 and 2012 was performed. The authors’ traditional technique (TT) consisted of using standard monofilament absorbable suture to close the common JJ enterotomy in a single running layer and to create the GJ with a two-layer anastomosis. A novel technique (NT) was introduced using knotless unidirectional barbed monofilament absorbable suture to perform both tasks. A comparison between these two techniques was performed.

Results

In this study, 84 patients with a mean body mass index of 41.7 ± 4.7 kg/m² underwent laparoscopic gastric bypass using a hand-sewn technique. For the 84 patients, 75 primary procedures (89.3 %) and 9 revisional procedures (10.7 %) were performed. In 38 procedures (45.2 %), the TT was used, whereas 46 cases (54.8 %) were managed using the NT. For the primary procedures, the average operating room times were slightly faster in the NT group (178.9 ± 44.4 vs 154.2 ± 74.7 min; p = 0.08). The average hospital length of stay was comparable between the two groups (2.3 ± 0.7 vs 2.6 ± 1.4 days; p = 0.25). A 30-day follow-up assessment was obtained for all 84 patients, without a significant difference in the overall complication rate between the two groups (TT 18.4 % vs NT 13 %; p = 0.77). No complications were secondary to the JJ closure or gastrojejunostomy. The complications included bleeding (n = 1), small bowel obstruction (n = 1), dehydration (n = 2), esophagitis (n = 1), and subarachnoid hemorrhage (n = 1). No anastomotic leak or stenosis occurred in either group. The mean percentage of excess weight loss at 1 month was 21.3 % ± 5.4 %, without a significant difference between the two groups.

Conclusion

In the study cohort, the use of knotless unidirectional barbed suture instead of traditional monofilament absorbable suture had similar 30-day outcomes and appears to be a feasible option for laparoscopic bowel closure and anastomosis creation.     

Comparison of Standard Suture vs Barbed Suture for Closing the Porcine Knee Joint: Evaluation of Biomechanical Integrity and Permeability

Background

This study aimed to compare the biomechanical strength and permeability of barbed vs traditional suture for closure of the porcine knee joint.

Laparoscopic gastrointestinal anastomoses using knotless barbed sutures are safe and reproducible: a single-center experience with 201 patients

Background

Intestinal anastomosis is a complex procedure during laparoscopy, mainly due to the difficulties knotting the sutures. Unidirectional barbed sutures have been proposed to simplify wall and mesentery closure, but the results for intestinal anastomosis are not clear. This study aimed to establish the feasibility and the safety of laparoscopic intestinal anastomosis using barbed suture.

Methods

Between June 2011 and May 2012, 15-cm-long unidirectional absorbable barbed sutures (V-Loc; Covidien, Mansfield, MA, USA) were used for all laparoscopic intestinal anastomoses: one suture for closure of intestinal openings after mechanical anastomoses and two sutures for hand-sewn anastomoses.

Results

Over a 1-year period, 201 consecutive patients required 220 laparoscopic anastomoses for gastrojejunostomy (n = 177; 172 during Roux-en-Y gastric bypass and 5 after gastrectomy), ileocolostomy (n = 15), colocolostomy (n = 1), esophagojejunostomy (n = 5), and jejunojejunostomy (n = 22; 4 after small bowel resection and 18 during gastric bypass or gastrectomy). Senior and training surgeons performed 209 closures of intestinal openings and 11 hand-sewn anastomoses. There was no conversion to usual sutures. One fistula occurred in an esophagojejunostomy and was managed conservatively. One self-limited anastomotic bleeding occurred, and no anastomotic stenosis occurred during 6 months of follow-up evaluation.

Conclusions

The use of knotless barbed suture for laparoscopic intestinal anastomosis is safe and reproducible.     

Unidirectional barbed suture versus interrupted vicryl suture in vaginal cuff healing during robotic-assisted laparoscopic hysterectomy

This study examined the performance of unidirectional barbed suture versus polyglactin 910 with respect to vaginal cuff healing in robotic-assisted total laparoscopic hysterectomy (RATLH). This was a retrospective cohort study of 93 patients who underwent RATLH in a teaching hospital from July 2008 to June 2012. In the first 44 patients, the vaginal cuff was closed by interrupted polyglactin (Vicryl) 2–0 suture. In the following 49 patients, unidirectional barbed suture (V-loc) in a running fashion was used for cuff closure. Patients were seen 2 and 6 weeks postoperatively to evaluate cuff healing. Age, tobacco use, hemoglobin, deliveries, uterine weight, menopause, steroid use, underlying health problems, and concomitant procedures were found not to be significantly different between the two groups. There was one cuff dehiscence in the unidirectional barbed suture group and none in the interrupted polyglactin group (P > 0.05). The mean cuff healing time (8.5 vs. 7.7 weeks), incidence of cuff cellulitis (4.6 vs. 4.1 %), and postoperative bleeding (22.7 vs. 14.3 %) were not statistically significantly different between polyglactin and barbed suture closures, respectively (P > 0.05). However, polyglactin suture was associated with greater presence of granulation tissue than barbed suture (27.3 vs. 8.2 %, odds ratio = 3.34, P < 0.05). Unidirectional barbed suture cases were associated with shorter total operative times (220.2 vs. 272.8 min) and less estimated blood loss (164.8 vs. 274.9 ml); however, cuff closure times were not specifically measured. In our study, unidirectional barbed suture was identified as possibly superior to polyglactin cuff closure because of less observed granulation tissue, shorter operative duration, and lower estimated blood loss. However, there was no statistical difference in cuff healing time, cuff dehiscence, cellulitis, or postoperative bleeding between the two groups. A prospective randomized trial would be necessary to confirm these findings.

The application of the V-Loc closure device for gastrointestinal sutures: a preliminary study

Background

Leakage is one of the major complications in gastrointestinal surgery. This preliminary study compared a new barbed absorbable thread for gastrointestinal sutures with monofil suture material in a cadaver model.

Methods

In this study, mechanical experiments were performed in 20 recently deceased individuals. Incisions were made in the small intestine, colon, and stomach, and then sutures were created with the V-Loc closure device and monofil suture material. Intestinal bursting pressure was measured by inserting a balloon and slowly filling it with air until there was a dehiscence, or wall or suture rupture.

Results

The bursting pressures differed significantly between the two sutures in the small intestine, showing the advantage of the V-Loc closure device, which had a mean bursting pressure of 116.2 mmHg compared with 110 mmHg for the monofil suture (p = 0.003). The mean bursting pressure did not differ significantly between the two sutures in the colon and the stomach. The mean bursting pressures for the V-Loc closure device were 141.3 mmHg (stomach) and 137.2 mmHg (colon) compared with the monofil suture material bursting pressures of 133 mmHg (stomach) and 134.8 mmHg (colon).

Conclusions

Because the bursting strength of the sutures created with monofil suture material differs significantly from that of the V-Loc closure device, the V-Loc suture material should be used for gastrointestinal sutures. Although the two sutures did not differ significantly in the colon or the stomach, the V-Loc closure device should be used for these as well because its advantages may overrule those of the monofil suture. No knot tying is required, and the operating time can be shorter. Especially for laparoscopic surgery, the V-Loc closure device is recommended.     

单向倒刺线在腹腔镜肝叶切除联合术中胆道探查中的运用

目的:探讨单向倒刺缝线在腹腔镜下肝叶切除联合术中胆道探查中应用的安全性及有效性。方法:回顾性分析2014年12月—2015年8月期间24例行腹腔镜肝切除联合术中胆道探查术的患者资料,其中10例采用传统缝线缝合胆管(传统缝线组),14例术中采用倒刺线缝合胆管(倒刺线组),比较两组的相关临床资料。结果:所有患者均手术成功,两组患者术前一般资料、术中出血量、术后并发症发生率(肺部感染)、术后住院时间差异均无统计学意义(均P0.05);但倒刺线组手术时间(230.50 min vs.354.68 min)、胆总管缝合时间(5.33 min vs.33.82 min)、肝管缝合时间(9.04 min vs.25.14 min)均明显少于传统缝线组(均P0.05)。所有患者出院1个月返院行T管造影,拔除T管,无结石残留、胆汁漏、胆管狭窄。结论:单向倒刺缝线用于腹腔镜下肝叶切除联合胆道探查术安全、可行,可吸收倒刺缝线的使用可以降低腹腔镜下缝合难度,缩短手术时间和学习曲线,而不增加胆汁渗漏的风险。     

Barbed Versus Usual Suture for Closure of the Gastrojejunal Anastomosis in Laparoscopic Gastric Bypass: a Comparative Trial

Background

Laparoscopic Roux-en-Y gastric bypass is one of the main bariatric procedures that require safe and reproducible anastomosis. The objective of this study is to compare the risk of leaks and stenosis of a mechanical gastric pouch jejunal anastomosis between the usual interrupted sutures and a continuous barbed suture for gastrojejunotomy, in order to reduce procedure time and costs.

Methods

A comparative trial of 100 consecutive patients undergoing laparoscopic Roux-en-Y gastric bypass was performed between October 2010 and July 2011. The population was divided into two groups of 50 consecutive patients. In the first group, gastrojejunotomy was sutured with resorbable interrupted sutures and the second with continuous barbed suture. Diabetes, body mass index and the American Society of Anaesthesiology score were compared. The time required for suturing and the incidence of anastomotic leaks and stricture were also compared after 6 months.

Results

No fistulas or anastomotic stenoses had occurred at post-operative month 6 in either group. Gastrojejunotomy suture time was significantly shorter in the barbed suture group (11 versus 8.22 min; p?<?0.01). Total costs of material to complete the reconstruction were significantly lower in the barbed suture group (€26.69 versus €18.33; p?<?0.001).

Conclusions

The use of barbed suture is as safe as usual sutures and allows easier and faster suture in the closure of gastrojejunotomy. This suture could be incorporated in the standard laparoscopic Roux-en-Y gastric bypass technique.     

Staple Line Reinforcement During Laparoscopic Sleeve Gastrectomy: Absorbable Monofilament,Barbed Suture,Fibrin Glue,or Nothing? Results of a Prospective Randomized Study

Background

Laparoscopic sleeve gastrectomy (LSG) is associated with serious complications, such as staple line (SL) leaks and bleeding. In order to prevent the occurrence of these complications, surgeons have advocated the need to strengthen the staple line. The aim of this randomized controlled study was to compare the efficacy of three different ways of strengthening of the SL in LSG in preventing surgical post-operative complications.

Methods

Between April 2012 and December 2014, 600 patients (pts) scheduled for LSG were prospectively randomized into groups without SL reinforcement (group A) or with SL reinforcement including fibrin glue coverage (group B), or oversewn SL with imbricating absorbable (Monocryl?; group C) or barbed (V lock®) running suture (group D). Primary endpoints were post-operative leaks, bleeding, and stenosis, while secondary outcomes consisted of the time to perform the staple line reinforcement (SLR) and total operative time.

Results

Mean SLR operative time was lower for group B (3.4?±?1.3 min) compared with that for groups C (26.8?±?8.5 min) and D (21.1?±?8.4 min) (p?<?0.0001). Mean total operative time was 100.7?±?16.4 min (group A), 104.4?±?22.1 min (group B), 126.2?±?18.9 min (group C), and 124.6?±?22.8 (group D) (p?<?0.0001). Post-operative leaks, bleeding, and stenosis were recorded in 14 pts (2.3 %), 5 pts (0.8 %), and 7 pts (1.1 %), respectively, without statistical difference between the groups.

Conclusion

Our study suggests that SLR during LSG, with an imbricating or non-imbricating running suture or with fibrin glue, is an unrewarding surgical act with the sole effect of prolonging the operative time.

     

Randomized Controlled Trial of Barbed Polyglyconate Versus Polyglactin Suture for Robot-Assisted Laparoscopic Prostatectomy Anastomosis: Technique and Outcomes

Background

Transperitoneal robot-assisted laparoscopic prostatectomy (RALP) urethrovesical anastomosis is a critical step. Although the prevalence of urine leaks ranges from 4.5% to 7.5% at high-volume RALP centers, urine leaks prolong catheterization and may lead to ileus, peritonitis, and require intervention. Barbed polyglyconate sutures maintain running suture line tension and may be advantageous in RALP anastomosis for reducing this complication.

Objective

To compare barbed polyglyconate and polyglactin 910 (Vicryl, Ethicon, Somerville, NJ, USA) running sutures for RALP anastomosis.

Design, setting, and participants

This was a prospective, randomized, controlled, single-surgeon study comparing RALP anastomosis using either barbed polyglyconate (n = 45) or polyglactin 910 (n = 36) sutures.

Surgical procedure

RALP anastomosis using either barbed polyglyconate or polyglactin 910 sutures was studied.

Measurements

Operative time, cost differential, perioperative complications, and cystogram contrast extravasation by anastomosis suture type were measured.

Results and limitations

Although baseline characteristics and overall operative times were similar, barbed polyglyconate sutures were associated with shorter mean anastomosis times of 9.7 min versus 9.8 min (p = 0.014). In addition, anastomosis with barbed polyglyconate rather than polyglactin 910 sutures was associated with more frequent cystogram extravasation 8 d postoperatively (20.0% vs 2.8%; p = 0.019), longer mean catheterization times (11.1 d vs 8.3 d; p = 0.048), and greater suture costs per case ($51.52 vs $8.44; p < 0.001). After 8 of 29 (27.6%) barbed polyglyconate anastomosis sites demonstrated postoperative day 8 cystogram extravasation, we modified our technique to avoid overtightening, reducing cystogram extravasation to 1 (6.3%) of 16 subsequent barbed polyglyconate anastomosis sites. Potential limitations include small sample size and the single-surgeon study design.

Conclusions

Compared to traditional sutures, barbed polyglyconate is more costly and requires technical modification to avoid overtightening, delayed healing, and longer catheterization time following RALP.     

The effects of barbed suture on watertightness after knee arthrotomy closure: a cadaveric study

Background

Wound closure is one of the crucial aspects of total knee arthroplasty (TKA) for patients who perform high-flexion activities of daily living, because the joint capsule is highly stretched and integrity of the arthrotomy closure must be maintained. Watertightness of the knee joint is a different aspect of the repair integrity of arthrotomy closure and is being noticed with increasing usage of the drain clamp method for blood management after TKA. Recently, the barbed knotless suture has been growing in popularity as a strong, secure closure appropriate for high-tension areas, such as the fascia and joint capsule. The purpose of this study was to compare the barbed knotless suture with simple interrupted suture in cadaveric knees.

Methods

Nine fresh-frozen cadaveric lower extremities were used. After placing a parapatellar incision and setting a closed suction drain, arthrotomies were closed randomly using three suture materials: simple interrupted absorbable suture (No. 0 PDS, group C); or a single running knotless barbed suture Stratafix with 8N (group BS-8N) or 15N (group BS-15N) of tension. After arthrotomy closure, saline was injected in a retrograde manner into the joint through a drain until saline started to leak from the joint. Peak values for intra-articular pressure and infusion volume in each group were recorded and compared.

Results

Mean infusion volumes were 13.0?±?7.2?ml, 38.6?±?10.7?ml, and 5.1?±?2.5?ml in groups BS-8N, BS-15N, and C, respectively. Mean intra-articular pressures were 0.67?±?0.47?kPa, 9.44?±?4.55?kPa, and 0.56?±?0.44?kPa in groups BS-8N, BS-15N, and C, respectively. Infusion volume and joint internal pressure were significantly higher in group BS-15N than in groups BS-8N (p =?0.008) or C (p =?0.04).

Conclusions

Barbed suture with 15N appears appropriate for maintaining maximal watertightness after knee joint capsule closure, offering successful drain clamping, higher resistance to early mobilization protocols, and subsequent achievement of early deep knee flexion after TKA.

     

The Impact of Preoperative Weight Loss Before Laparoscopic Gastric Bypass

Background

The impact of preoperative weight loss on outcomes following laparoscopic Roux-en-Y gastric bypass (LRYGB) is a controversial issue. We evaluated our outcomes of LRYGB in patients who lost different amount of weight prior to surgery.

Methods

Patients who underwent primary LRYGB were divided in three groups on the basis of preoperative weight loss percentage. Group A comprised 166 patients, who lost <5 % of their weight preoperatively; group B comprised 239 patients who lost >5 to 10 % and group C included 143 patients who lost >10 %. Intra- and postoperative complications at 30 days, hospital stay, and outcomes were evaluated.

Results

Significant difference was found in operative (mean ± SD) time [104.43?±?36.40 min in group A, 80.08?±?23.07 min in group B, and 76.99?±?23.23 min in group C; p?<?0.001 in group A versus group B or group C; p?=?0.210 in group B versus group C]. Difference in hospital stay was significant (3.33?±?3.22 days in group A, 2.10?±?2.77 in group B, and 1.87?±?1.44 in group C; p?<?0.001 in group A versus groups B or C). Overall postoperative morbidity rate was 33.13 % in group A, 19.25 % in group B, and 11.89 % in group C, with significant difference in group A versus groups B or C (p?=?0.002 and p?<?0.001). Mean excess weight loss was significantly higher (72.7 %) in group C versus group A (63.1 %) (p?=?0.015) at 12 months.

Conclusions

Weight loss >5 % prior to LRYGB may reduce morbidity, and preoperative weight loss >10 % may improve weight loss outcomes at 1-year follow-up.     

Vaginal Cuff Closure during Robotic-Assisted Total Laparoscopic Hysterectomy: Comparing Vicryl to Barbed Sutures

Background and Objectives:

Empirical evidence is needed to assess clinical appropriateness of any new surgical device or material. Differences in surgical outcomes between Vicryl figure-of-8 and V-Loc barbed sutures for vaginal cuff closure during robotic hysterectomy were assessed.

Methods:

We examined the electronic medical records of 202 patients who underwent scheduled robotic-assisted total laparoscopic hysterectomy for benign indications, without concomitant urogynecologic procedures, between January 2008 and November 2010 at the Henry Ford Health System academic medical center. Cuff closure approach was selected by the surgeon. Data on demographics, vaginal cuff suture type, body mass index (BMI), estimated blood loss (EBL), perioperative hemoglobin change, procedure duration, hospital length of stay (LOS), specimen weight, and postoperative complications were obtained.

Results:

The average age was 46 y (SD = 8.0 y). Women with Vicryl figure-of-8 closures (n = 133) were more likely than women with V-Loc barbed suture closures (n = 69) to have had a LOS > 1 d (48/133, 36.1% vs. 12/69, 17.4%; chi square P = .006), greater EBL (median 75 vs. 50 mL, Wilcoxon Rank Sum=WRS P < .001), and longer procedure durations (175 vs. 135 min, WRS P < .001). These differences persisted even after considering uterine weight, BMI, smoking status, and concomitant oophorectomy. No differences with respect to the frequency of major (2 in each closure type) or minor complications were observed (P = .36).

Conclusions:

There were no differences in complications between the Vicryl figure-of-8 and V-Loc barbed sutures in our sample. However, the latter had lower EBL and shorter procedure duration and LOS.     

Does Barbed Suture Lower Cost and Improve Outcome in Total Knee Arthroplasty? A Randomized Controlled Trial

Background

Wound closure is key to prevent infection, facilitate immediate rehabilitation, and improve efficiency of total knee arthroplasty (TKA). Continuous knotless suturing with barbed suture can potentially save time and distribute tension more evenly. However, its role in TKA in terms of cost-effectiveness and wound complications is not clear. This study aims at comparing barbed and traditional sutures' wound closure time and cost in primary TKA.

Robotic Roux-en-Y Gastric Bypass,is it Safer than Laparoscopic Bypass?

Background

Along with the development of technology, robotic approach is being performed for laparoscopic Roux-en-Y gastric bypass (LRYGB). Some literatures reported same or better peri-operative outcomes with the robotic procedure. The aim of this study is to compare our experience in robot-assisted LRYGB (RA-LRYGB) with LRYGB in terms of peri-operative outcomes.

Methods

From January 1, 2012 to April 30, 2014, a total of 270 patients underwent LRYGB by one surgeon at a single institution. Of these, 64 cases were done robotically. A retrospective review was performed for these patients, noting the outcomes and complications of the procedure.

Results

The 64 RA-LRYGB patients had a mean age of 45.9?±?10.0 years (range, 23–67) and a mean preoperative body mass index (BMI) of 48.4?±?7.9 kg/m² (range, 33.8–76.4). The 207 LRYGB patients had a mean age of 45.0?±?10.7 years (range, 21–67) and a mean preoperative BMI of 48.4?±?8.1 kg/m² (range, 34.0–80.4). These two groups were clinically comparable. Mean length of hospital stay was 3.0?±?4.1 days (range, 1–19) in RA-LRYGB patients, significantly longer than 1.6?±?1.7 days (range, 1–17) in LRYGB patients (p?<?0.01). Thirty-day readmission rate was 9.3 % (n?=?6) in the RA-LRYGB group and 6.8 % (n?=?14) in the LRYGB group. Higher leak rate was noticed in RA-LRYGB patients at 7.8 % (n?=?5), compared to 0.5 % (n?=?1) in LRYGB patients (p?<?0.01). All the leaks occurred at the pouch level in the RA-LRYGB group, while one leak from the LRYGB group occurred at the gastrojejunal anastomosis site.

Conclusions

Robot-assisted Roux-en-Y gastric bypass may result in higher leak rate at the pouch level, when compared to that of laparoscopic procedures.

     

Does Robotic Roux-en-Y Gastric Bypass Provide Outcome Advantages over Standard Laparoscopic Approaches?

Objective

The aim was to compare clinical outcomes of patients treated with totally robotic Roux-en-Y gastric bypass (TRRYGB) with those treated with the different laparoscopic Roux-en-Y gastric bypass (LRYGB) techniques.

Summary Background Data

The clinical benefit of the robotic approach to bariatric surgery compared to the standard laparoscopic approach is unclear. There are no studies directly comparing outcomes of TRRYGB with different LRYGB techniques.

Methods

Outcomes of 578 obese patients who underwent RYGB between 2011 and 2014 at an academic center were assessed. Multivariable analysis and propensity matching were used for comparing TRRYGB to different LRYGB techniques, including 21-mm EEA circular-stapled gastrojejunal anastomosis (GJA, LRYGB-21CS), linear-stapled GJA (LRYGB-LS), and hand-sewn GJA (LRYGB-HS).

Results

The TRRYGB technique required a longer mean operative time compared to the other groups, respectively 204?±?46 vs. 139?±?30 min (LRYGB-21CS), 206?±?37 vs. 158?±?30 min (LRYGB-LS), and 210?±?36 vs. 167?±?30 min (LRYGB-HS). TRRYGB experienced a lower stricture rate (2 vs. 17%, P?=?0.003), shorter hospital stay (2.6?±?1.2 vs. 4.3?±?5.5 days, P?=?0.008), and lower readmission rate (12 vs. 28%, P?=?0.009). No significant differences in outcomes were observed when comparing RRYGB to LRYGB-LS or LRYGB-HS.

Conclusions

TRRYGB increases operative time compared to all LRYGB techniques. TRRYGB was superior to LRYGB-21CS in terms of significantly shorter hospital stay, lower readmission rate, and less frequent GJA stricture formation. TRRYGB provides no clinical advantages over the LRYGB-LS and LRYGB-HS techniques.

     

Risk of Gastrojejunal Anastomotic Stricture with Multifilament and Monofilament Sutures after Hand-Sewn Laparoscopic Gastric Bypass: A Prospective Cohort Study

Background

Gastrojejunal (GJ) stricture is one of the most common late complications after laparoscopic Roux-en-Y gastric bypass (LRYGBP) with a hand-sewn anastomosis. The object of this study was to assess the risk of stricture for two types of resorbable suture (multifilament and monofilament) in a series of LRYGBPs performed by the same surgeon.

Methods

Design: Prospective cohort study. The study population consisted of a series of consecutive morbidly obese patients who underwent primary hand-sewn LRYGBP between March 2004 and May 2008 at the University Hospital in Getafe, Madrid, Spain. The study comprised 242 LRYGBPs with a four-layer continuous hand-sewn anastomosis using absorbable 3/0 gauge suture. The suture material was Ethicon Vicryl® multifilament in the first 105 cases and Ethicon Monocryl® monofilament in the following 137 cases. All patients were followed up monthly for the first 6 months and then every 6 months after that.

Results

The mean BMI was 46?±?4 for the multifilament cohort and 48?±?6 for the monofilament cohort with no significant difference between the two (p?=?0.567). There were no anastomotic leaks, and no cases of marginal ulcer, abscess, abdominal sepsis, deep vein thrombosis, or pulmonary embolism were recorded. No cases required conversion to open surgery, and perioperative mortality was zero. In all, 11 cases of stricture (4.4%) were recorded, 10 in the multifilament suture cohort (9.5%), and only one in the monofilament suture cohort (0.7%; p?=?0.001). The odds ratio was 14.3 (95% CI?=?1.8–113.4). The mean outpatient follow-up period was 30 months (range?=?6–42).

Conclusions

Anastomotic GJ stricture is a common and well-known complication of laparoscopic gastric bypass for morbid obesity. Hand sewing with monofilament suture significantly lowered the frequency of this complication, and hence, monofilament should be the suture material of choice for this suturing technique.     

Learning curve and robot set-up/operative times in singly docked totally robotic Roux-en-Y Gastric bypass

Background

The robotic platform might offer superior ergonomics over other minimally invasive approaches. However, the increased time required for instrument set-up, operations, and surgical training are perceived as major drawbacks. There is limited literature on this topic, therefore we report our experience at an academic tertiary medical center in the USA. The primary aim of this study was to analyze the learning curve and the times for necessary steps for singly docked totally robotic Roux-en-Y gastric bypass (RREYGB).

Materials and methods

From November 2010 to April 2013, all consecutive patients who underwent RREYGB were retrospectively analyzed from a prospectively maintained database. Variables of interest for this study were patient demographics, preoperative body mass index, previous surgical history, clinically relevant perioperative events, and operative times for various steps in the procedure.

Results

During the study period, a total of 32 patients were enrolled. The mean age was 39.9 ± 9.7 years (range 25–60), preoperative weight was 120.9 ± 21.5 kg (range 76.7–184.6), and body mass index (BMI) was 44.7 ± 5.3 kg/m² (range 36.1–61). The mean total operative time was 187.3 ± 36.4 min (range 130–261). The time necessary for trocar placement was 11.9 ± 4.5 min (range 4–23), robot set-up was 8.5 ± 3.6 min (range 3–20), pouch creation was 32 ± 10.11 min (range 16–56), gastrojejunal anastomosis was 59.5 ± 12.3 min (range 39–90), jejunojejunal anastomosis was 33.5 ± 9.6 min (range 18–65), and endoscopy/hemostasis was 12.9 ± 7.2 min (range 2–34). Operative time significantly improved after eight cases.

Conclusion

In a high-volume established robotic bariatric center, robot set-up, operative times, and learning curve are shorter than previously reported.     

单向倒刺线在腹腔镜胆总管探查一期连续缝合中的应用

【摘 要】 目的 探讨单向倒刺线连续缝合在腹腔镜胆总管探查一期缝合术中闭合胆总管的安全性和有效性。方法 对2016年6月至2017年12月西安交通大学第一附属医院进行腹腔镜胆总管探查一期缝合术治疗的81例胆总管结石患者进行前瞻性研究。按照随机数字表法,患者分为单向倒刺线连续缝合组（41例）和普通可吸收线连续缝合组（40例）。比较两组患者胆总管闭合缝合时间,术后并发症情况,术后住院时间及随访情况。结果 两组患者均手术成功,术中结石取净,无术中并发症。倒刺线组胆总管缝合时间明显少于普通线组[（11.4±2.0）min vs （15.6±3.5）min,t=-6.67,P < 0.05];两组胆漏发生率（2.4% vs 5.0%）,急性胆管炎发生率（4.9% vs 5.0%）,术后平均住院时间[（4.4±1.2）d vs（4.4±1.6）d]差异均无统计学意义（P > 0.05）。所有患者均获得随访,随访半年以上者倒刺线组18例,普通线组15例,尚未见结石残余、结石复发或胆管狭窄情况。结论 单向倒刺缝线连续缝合用于腹腔镜胆总管探查一期缝合术安全可行,可以降低腹腔镜下缝合难度,缩短缝合时间,并且不增加并发症风险.     

倒刺缝线在腹腔镜胆总管囊肿切除术中的应用

目的初步探讨单向倒刺缝线在完全腹腔镜下成人胆总管囊肿切除术中应用的安全性及有效性。方法回顾性分析2012年8月-2014年10月期间行完全腹腔镜下成人胆总管囊肿切除术的10例病例资料。结果全组病例均成功完成手术,无中转开腹。手术时间（194.5±20）min,160～225 min,胆管空肠吻合时间为（19.1±4.0）min,13～25 min,空肠空肠吻合时间为（17.5±2.0）min,12～21 min。术中出血（64.0±43.2）ml,10～150 ml,下床活动时间（1.6±0.7）d,排气时间（2.5±0.7）d,术后住院时间（7.0±1.7）d,5～10 d10围手术期无并发症发生。10例均获得随访。随访时间2～26个月,平均随访12.7月。1例患者术后出现反流性胆管炎,经抗感染等治疗后痊愈。结论单向倒刺缝线用于完全腹腔镜下胆肠吻合是安全、有效的。可吸收倒刺缝线的应用能够降低腹腔镜下缝合难度、缩短缝合时间及手术时间、缩短学习曲线,有利于本术式的广泛开展。
