Effect of interrupted suture and continuous suture on perineal rehabilitation of parturients: a Meta-analysis / 中国实用护理杂志

Objective:To explore the effect of perineal lateral incision and continuous suture of deep and superficial Ⅱdegree laceration on postoperative perineum rehabilitation of parturients.Methods:Randomized controlled trials of intervention effects on postoperative maternal wound rehabilitation using continuous sutures and interrupted sutures of mucosal, muscle, and skin layers after perineal lateral resection and Ⅱdegree lacerations were searched in Cochrane Library, PubMed, Medline, Embase, Science direct, China Biology Medicine, China National Knowledge Infrastructune, Wanfang Database, VIP Database. The retrieval time limit was from database establishment to October 1, 2020. using RevMan 5.3 software for statistical processing.Results:After searching and screening, 12 articles were finally included. The total sample size was 2 827 cases. After the two groups used different suture techniques, the results of Meta analysis showed that the pains ( MD=1.02, 95% CI=1.02-1.06), the suture time ( MD=-4.59, 95% CI=-7.29 - -1.91) and the healing condition ( MD=-0.55, 95% CI=-0.71 - -0.39) of the two groups were compared, the differences were significant (all P<0.01). Conclusions:In the suture of perineal lateral incision and Ⅱdegree laceration, continuous suture technique is used to suture the mucosal layer, muscle layer, and cortex, which can reduce the suture time, reduce the pain of the parturient, and is beneficial to the healing of the wound. It can be clinically based on the parturient. It can be used in accordance with the neatness and depth of the mouth and the needs of the parturient.

Clinical comparative observation of continuous and interrupted suture of omentopexy in laparoscopic sleeve gastrectomy / 国际外科学杂志

Objective:To compare the safety of continuous suture and interrupted suture in Laparoscopic Sleeve Gastrectomy and Omentopexy.Methods:The retrospective study include 121 patients who underwent Laparoscopic Sleeve Gastrectomy and Omentopexy in the Department of Obesity and Metabolic Surgery of the First Affiliated Hospital of Jinan University from January 2019 to March 2020.Among the 121 patients, 40 were males and 81 females, with an average age of (30.17±10.16) and (27.10±11.03), respectively. Among them, 70 patients used continuous suture during OP (continuous suture group), and 51 patients used intermittent suture (interrupted suture group). The operation time, intraoperative blood loss, postoperative pain score, postoperative complications were compared between the two groups. Normally distributed measurement data were measured as (mean ± standard) deviation ( Mean± SD), and t test was used to count the comparison between the two groups. The χ2 test was used to compare the measurement data between groups. The rank data used Wilconxon rank sum test. Results:(1) Intraoperative conditions: the operative time and intraoperative blood loss in the continuous suture group were (124.89±37.69) min and (7.3±2.5) mL, respectively. In the interrupted suture group, the above indexes were (124.80±35.53) min and (7.0±2.5) mL, respectively. There was no significant difference between the two groups ( t=0.012, 0.709, P>0.05). (2) Postoperative conditions: postoperative pain score and postoperative hospital stay in the continuous suture group were: mild pain in 45 cases, moderate pain in 25 cases, painless and severe pain in 0 cases, (9.3±3.2) d, respectively. In the interrupted suture group, the above indicators were 39 cases of mild pain, 12 cases of moderate pain, 0 cases of painless and severe pain, (8.7±2.1) d, and there was no statistical significance between the two groups ( Z=-1.431, P>0.05, t=1.149, P>0.05). In the continuous suture group, postoperative abdominal distension occurred in 8 cases, nausea and vomiting in 32 cases, gastroesophageal reflux in 17 cases by upper digestive tract imaging, contrast agent slowly passed through the residual stomach/anastomotic site in 14 cases, gastric volvulus in 6 cases, and no postoperative infection or anastomotic leakage occurred. In the interrupted suture group, the above indexes were 10 cases, 25 cases, 14 cases, 10 cases, gastric volvulus in 1 cases, and no postoperative infection or anastomotic leakage occurred. There was no significant difference in the above indicators between the two groups ( χ2=1.559, 0.010, 0.155, 0.003, 1.308, P>0.05). Conclusions:In laparoscopic sleeve gastrectomy and omentopexy, there is no significant difference between the continuous suture and interrupted suture in terms of operation time, intraoperative blood loss and postoperative complications. The surgeon can choose a suitable suture method based on his own judgment and experience.

Influence analysis of full-thickness continuous suture method and layer interrupted suture method in emergency abdominal operation closure / 中国医师进修杂志

Objective To assess the influence of full-thickness continuous suture method and layer interrupted suture method in emergency abdominal operation closure.Methods Two hundred and thirtyseven patients of emergency abdominal operation were divided into full-thickness continuous suture method group (145 cases) and layer interrupted suture method group (92 cases) according to the suture method.The rate of incision liquefaction and infection,time of incision suture were compared between the 2 groups,the patients with incision liquefaction and infection were given bacterial culture.Results The time of incision suture in full-thickness continuous suture method group was significantly shorter than that in layer interrupted suture method group [(18.37 ± 7.42) min vs.(25.92 ± 5.79) min],there was statistical difference (P ＜0.01).There were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing between the 2 groups (P ＞ 0.05).In full-thickness continuous suture method group,the rate of incision liquefaction and infection in median incision was significantly lower than that in rectus abdominis incision [18.58％ (21/113) vs.31.25％ (10/32)],the rate of incision primary healing was significantly higher than that in rectus abdominis incision [81.42％ (92/113) vs.68.75％ (22/32)],there were statistical differences (P ＜ 0.05).In layer interrupted suture method group,there were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing between median incision and rectus abdominis incision [33.33％ (23/69) vs.26.09％(6/23),66.67％ (46/69) vs.73.91％ (17/23),P ＞ 0.05].The rate of incision liquefaction and infection in median incision of full-thickness continuous suture method group was significantly lower than that in median incision of layer interrupted suture method group,and the rate of incision primary healing was significantly higher than that in median incision of layer interrupted suture method group,there were statistical differences (P ＜ 0.05).There were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing in rectus abdominis incision between the 2 groups (P ＞ 0.05).The bacterial culture result in patients with incision liquefaction and infection showed positive was in 26 cases,in full-thickness continuous suture method group was in 10 cases (6.90％,10/145),in layer interrupted suture method group was in 16 cases (17.39％,16/92),there was statistical difference (P ＜0.05).The mostly bacterial of infection was Escherichia coli.Conclusions The full-thickness continuous suture in median incision can shorten operative time and reduce the rate of incision liquefaction and infection in emergency abdominal operation.Suture technique has important impact on incision healing.

Outcome of Abdominal Wound Closure Following Continuous and Interrupted Suture in Elective Laparotomy.

Closure is a crucial factor in laparotomy wound. Fascial layers provide the major tensile strength in wound closure. Poor wound healing and development of wound infection in incisional wounds are the common complications of open abdominal surgery. Continuous fascial closure commonly practiced and the interrupted closures are also practiced by some surgeon with an assumption that it causes less pain and less wound infection. The aim of this study was to determine the rate of postoperative wound infection and severity of wound pain following interrupted and continuous abdominal wound closure. A comparative cross-sectional study was done at the Department of surgery, Sylhet MAG Osmani Medical College Hospital from 1st July 2007 to 30th June 2008. A total 100 patients of clean-contaminated elective laparotomy were selected. The patients were randomly divided into two groups. Every odds number was included in group-I (interrupted suture) and every even number was included in group-II (continuous suture). Total 14% wound infection was detected in interrupted suture group where as wound infection was 18% in continuous suture group of wound closure. Though the wound infection is higher in group-II but the difference of wound infection is not statistically significant between two groups. The wound pain assessed in seven postoperative days was higher in continuous closure group than interrupted group but the difference was not significant. There is no significant difference of wound infection and wound pain between interrupted and continuous suture group in clean-contaminated laparotomy.

Comparison of Corneal Astigmatism after Keratolasty with 3 Kinds of Suture Techniques

In order to evaluate the comparison of corneal astigmatism after keratoplasty with 3 kinds of suture techniques, penetrating keratoplasty was performed in 25 patients(25 eyes) with different suture techniques, single continuous(group I, N=7), interrupted(II, N=7), and combined sutures(III, N=11) with 10-0 nylon. In group I, suture control was made from postoperative 1 month and selective suture removal was done in group II and III. The corneal astimatism was analyzed prospectively with corneal topography more than 1 year in all except 2 patients. The amout of corneal astigmatism in group I, II and III at postoperatie 1 month was 2.12D, 3.14D and 3.08D respectively (P>0.05, Kruskal-Willis test) and showed marked reduction upon postoperative 3 months. At postoperative 1 year, corneal astigmatism of each group was 2,62D, 1.49D and 2,18D respectively(P>0.05). The corneal astigmatism between keratoconus and other corneal disorders was not statistically ignificant. Interrupted suture induced least corneal astigmatism after keratoplasty compared to other suture methods even if there was no statistical significance.

Astigmatism after Penetrating Keratoplasty According to Suture Methods

A large amount of corneal astigmatism after penetrating keratoplasty is a common problem. The purpose of this study was to find out which is the best suture method to minimize the postoperative corneal astigmatism. Among 35 eyes there were 7 eyes in interrupted suture group, 14 eyes in continuous suture group, and 14 eyes in combined suture group. In order to minimize postoperative astigmatism selective suture removal was done in interrupted suture group or combined suture group, and suture tension adjustment was made in continuous suture group. At postoperative 20 months the mean astigmastism was 5.97D in interrupted suture group, 3.66D in continuous suture group and 2.87D in combined suture group, respectively. There was no statistical significance. In spite of statistical insignificance, the astigmatism of continuous or combined suture group after penetrating keratoplasty was smaller than that of interrupted suture group after penetrating keratoplasty.

An Experimental Study of Microvascular patency Using the Suture Techniques / 대한정형외과학회잡지

The suture techniques to anastomose successfully small vassels of 1mm in diameter were continuous suture and interrupted suture, and patency rate of them has been estabilished by orthopaedic surgeon. In 1962, Chase and Schwarz reported better results with interrupted suture than with a continuous suture, Firsching reported less time using with continuous suture than with interrupted suture, but no difference in flow rate, in 1984 Lilly reported that interrupted suture does no result in stenosis of venous end to end anastomoses by continuous suturing technique, Mao reported that there was no statically significant difference between two suture methods in patency rate. The authors have experimentally studied the patency rate and histopathological findings of two suture techniques in the 20 Newzealand white rabbit at the department of Orthopaedic Surgery, Hanyang University Hospital and can be obtained the following results. l. In arterial patency, the interrupted suture and continuous suture were 100% in rate and patency rate in veins were 95% in interrupted suture and 75% in continuous suture. 2. Subintimal hyperplasia occured earlier in arteries than in veins and it may be due to the medial component of vessel. 3. In anastomoses of small vessel the accurate apposition of cut vessels edges decreased the thrombi formation of vessel.
