ABSTRACT

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is effective for the treatment of type 2 diabetes mellitus; however, the mechanism remains unclear. METHODS: The effects of RYGB on postprandial responses to three different diets (low carbohydrate (CH)-rich diet, high CH-rich diet, and fat-rich diet) of different nutritional composition in a Goto-Kakizaki (GK) diabetic rat model were assessed by measuring glucose tolerance, insulin resistance, incretin responses, and bile acid (BA) metabolism. RESULTS: GK-RYGB group rats lost weight and preferred low CH-rich diet, but there were no significant differences in BW among the different diets. Glucose tolerance and insulin resistance were improved in rats who underwent RYGB, together with higher levels of circulating BAs, plasma GLP-1, and PYY levels. GK-RYGB rats fed high CH-rich or fat-rich diet showed increased glucose level and insulin resistance, together with high plasma BA, GIP, and PYY levels compared to those fed a low CH-rich diet. CONCLUSION: RYGB improves glucose tolerance and insulin resistance which may be related to BA metabolism and hormone levels, and the nutrient composition of the diet affects the treatment effect of RYGB on T2DM.

ABSTRACT

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the efficacy of carbon nanoparticles in identifying lymph nodes and promoting parathyroid gland function recovery after thyroid carcinoma surgery along with central lymph node dissection. METHODS: A total of 231 patients who underwent thyroid carcinoma surgery combined with central lymph node dissection were divided into two groups: the CN group (intraoperative carbon nanoparticles injections) and the control group (no injection). Datas were collected respectively on the pre-operative, 1st, 7th and 30th postoperative days and monthly thereafter. While the pathological results (e.g. amount of incidental removed parathyroid glands and lymph nodes dissected), complications (e.g. rates of vocal cord paralysis, the neuromuscular symptoms, hypocalcemia and hypoparathyroidism), as well as follow-up outcomes of the serum Ca2+ and PTH levels were gathered and measured to be included in. RESULTS: In regard to the results of the pathological tests, the control group had a relatively higher incidence of incidental parathyroidectomy when compared to the CN group (P < 0.05). The mean number of central lymph nodes dissected was rather higher in the CN group than that of the control group (P < 0.05).With respect to the follow-up results, the CN group had an earlier and faster recovery of serum PTH levels as compared to the control group (P < 0.05). The serum PTH levels of the CN group were apparently higher than that of the control group at the first week and month postoperatively (P < 0.05). No significant differences were found in rates of long-term postoperative complications between the two groups (P > 0.05). CONCLUSION: Carbon nanoparticles play a key role in accurately identifying lymph nodes, reducing mistaken excision of parathyroid glands, accelerating rapid recovery of parathyroid function during thyroid carcinoma surgery with central lymph node dissection, without increasing the probability of postoperative complications.

ABSTRACT

AIM: In recent years, several studies with large sample sizes and recent follow-up data have been published comparing outcomes between laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication. It is now timely to be re-evaluated and synthesized long-term efficacy and adverse events of both total and partial posterior fundoplication. MATERIALS AND METHODS: Electronic searches for RCTs comparing the outcome after laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication were performed in the databases of MEDLINE, EMBASE, and the Cochrane Center Register of Controlled Trials. The data of evaluation in positive and adverse results of laparoscopic Nissen fundoplication and laparoscopic Nissen fundoplication were extracted and compared using meta-analysis. RESULTS: 13 RCTs were ultimately identified involving 814 (52.05%) and 750 (47.95%) patients who underwent laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication, respectively. The operative time, perioperative complications, postoperative satisfaction, recurrence, and the rates of medication adoption or re-operation due to recurrence were not significantly different between two groups. The two types of fundoplication both reinforced the anti-reflux barrier and elevated the lower esophageal sphincter pressure. However, rates of adverse results involving dysphasia, gas-bloat syndrome, inability to belch and re-operation due to severe dysphasia were significantly higher after LNF. In the subgroup analysis of wrap length≤2 cm, laparoscopic Nissen fundoplication was associated with a significantly higher incidence of postoperative dysphagia. However, in the subgroup wrap length>2 cm, the difference was not statistically significant. CONCLUSION: Laparoscopic Toupet fundoplication might be the better surgery approach for gastroesophageal reflux disease with a lower rate of postoperative adverse results and equal effectiveness as Laparoscopic Nissen fundoplication.

ABSTRACT

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is effective for type 2 diabetes mellitus (T2DM) patients with a body mass index (BMI) >35 kg/m(2). It is unknown whether it benefits those with a BMI ≤ 35 kg/m(2). In the last decade, the effect of bariatric procedures on metabolic outcomes in individuals who underwent surgery outside National Institutes of Health (NIH) guidelines (BMI ≤ 35 kg/m(2)) was both interesting and controversial. OBJECTIVE: We performed a systematic analysis evaluating the effect of RYGB for T2DM patients with a BMI ≤ 35 kg/m(2). METHODS: We searched databases (Embase, Ovid, PubMed, China National Knowledge Infrastructure [CNKI], and Cochrane Library) and relevant journals between January 1980 and October 2013. Keywords used in electronic searching included 'diabetes', 'gastric bypass', 'BMI', and 'body mass index'. Inclusion criteria were as follows: (1) patients who underwent RYGB; (2) sample size ≥ 15; (3) patients with a BMI ≤ 35 kg/m(2); and (4) follow-up ≥ 12 months. Exclusion criteria were as follows: (1) data extracted from a database; (2) trials for sleeve gastrectomy; (3) trials for laparoscopic banding; (4) trials for bilio-pancreatic diversion; and (5) trials for duodenojejunal bypass. Participants and intervention type 2 diabetes patients with BMI ≤ 35 kg/m(2) who underwent RYGB. Two investigators reviewed all reported studies independently. Data were extracted according to previously defined endpoints. A meta-analysis was performed for these parameters, with homogeneity among different trials. RESULTS: Nine articles fulfilled inclusion criteria. After 12 months, patients with T2DM had a significant decrease in their BMI postoperatively (p < 0.00001, weighted mean difference [WMD] -7.42, 95 % confidence interval [CI] -8.87 to -5.97), and remission of diabetes (glucose: p < 0.00001, WMD -59.87, 95 % CI -67.74 to -52.01; hemoglobin A1c p < 0.00001, WMD -2.76, 95 % CI -3.41 to -2.11). There were no deaths in all trials, and the complication rate was between 6.7 and 25.9 %. Mean length of hospital stay was 2.00 to 3.20 days, and mean operative time was from 72.8 to 112.0 min. In terms of study limitations, publication and selection bias were unavoidable. Trials with small sample sizes were excluded, which may lead to a selection bias. CONCLUSION: RYGB was effective for T2DM patients with BMI ≤ 35 kg/m(2). Further clinical studies with long-term follow-up data are necessary to clarify this issue.

ABSTRACT

BACKGROUND: This study aimed to compare the effects of laparoscopy vs. laparotomy on bacterial translocation and immunologic responses in a porcine model with peritonitis caused by small bowel injuries (SBIs). METHODS: Pigs with SBIs were first established, assigned into either the laparoscopy group or the laparotomy group, and then received surgical intervention. During 72 hours (72 hr) observation period, blood, and tissues of different organs were obtained for bacterial cultures; endotoxin and peripheral leukocyte were determined; serum levels of IL-6, TNF-α, and CRP were measured. RESULTS: Blood cultures confirmed systemic bacteremia in all animals and the endotoxin level was comparable between groups at 24 hr after surgery. However, two days later, positive bacteremia was only detected in four pigs following laparoscopy and five following laparotomy. Eight and four pigs during laparoscopy (seven and six pigs during laparotomy) had translocated bacteria in mesenteric lymph nodes (MLN) and liver. The 72 hr later, bacteria in MLN, liver, lung, and kidney was found in 2, 1, 2, and 0 pig after laparoscopy, respectively (3, 2, 2, and 1 pig after laparotomy). The peripheral blood monocytes (PBMC) counts remained at a much lower level after laparoscopy than after laparotomy. Serum IL-6, TNF-α, and CRP increased notably after both procedures when compared to preoperative levels. However, significantly faster and lower regression of IL-6, TNF-α, and CRP were observed in the laparoscopy group. CONCLUSION: Compared with laparotomy, laparoscopy does not result in increased bacterial translocation, but decrease IL-6, TNF-α, and CRP release.

ABSTRACT

AIM: To summarize our experience in the application of Crurasoft® for antireflux surgery and hiatal hernia (HH) repair and to introduce the work of Chinese doctors on this topic. METHODS: Twenty-one patients underwent HH repair with Crurasoft® reinforcement. Gastroesophageal reflux disease (GERD) and HH-related symptoms including heartburn, regurgitation, chest pain, dysphagia, and abdominal pain were evaluated preoperatively and 6 mo postoperatively. A patient survey was conducted by phone by one of the authors. Patients were asked about "recurrent reflux or heartburn" and "dysphagia". An internet-based Chinese literature search in this field was also performed. Data extracted from each study included: number of patients treated, hernia size, hiatorrhaphy, antireflux surgery, follow-up period, recurrence rate, and complications (especially dysphagia). RESULTS: There were 8 type I, 10 type II and 3 type III HHs in this group. Mean operative time was 119.29 min (range 80-175 min). Intraoperatively, length and width of the hiatal orifice were measured, (4.33 ± 0.84 and 2.85 ± 0.85 cm, respectively). Thirteen and eight Nissen and Toupet fundoplications were performed, respectively. The intraoperative complication rate was 9.52%. Despite dysphagia, GERD-related symptoms improved significantly compared with those before surgery. The recurrence rate was 0% during the 6-mo follow-up period, and long-term follow-up disclosed a recurrence rate of 4.76% with a mean period of 16.28 mo. Eight patients developed new-onset dysphagia. The Chinese literature review identified 12 papers with 213 patients. The overall recurrence rate was 1.88%. There was no esophageal erosion and the rate of dysphagia ranged from 0% to 24%. CONCLUSION: The use of Crurasoft® mesh for HH repair results in satisfactory symptom control with a low recurrence rate. Postoperative dysphagia continues to be an issue, and requires more research to reduce its incidence.

ABSTRACT

AIM: To evaluate the safety and effectiveness of laparoscopy compared with laparotomy for diagnosing and treating small bowel injuries (SBIs) in a porcine model. METHODS: Twenty-eight female pigs were anesthetized and laid in the left recumbent position. The SBI model was established by shooting at the right lower quadrant of the abdomen. The pigs were then randomized into either the laparotomy group or the laparoscopy group. All pigs underwent routine exploratory laparotomy or laparoscopy to evaluate the abdominal injuries, particularly the types, sites, and numbers of SBIs. Traditional open surgery or therapeutic laparoscopy was then performed. All pigs were kept alive within the observational period (postoperative 72 h). The postoperative recovery of each pig was carefully observed. RESULTS: The vital signs of all pigs were stable within 1-2 h after shooting and none of the pigs died from gunshot wounds or SBIs immediately. The SBI model was successfully established in all pigs and definitively diagnosed with single or multiple SBIs either by exploratory laparotomy or laparoscopy. Compared with exploratory laparotomy, laparoscopy took a significantly longer time for diagnosis (41.27 ± 12.04 min vs 27.64 ± 13.32 min, P = 0.02), but the time for therapeutic laparoscopy was similar to that of open surgery. The length of incision was significantly reduced in the laparoscopy group compared with the laparotomy group (5.27 ± 1.86 cm vs 15.73 ± 1.06 cm, P < 0.01). In the final post-mortem examination 72 h after surgery, both laparotomy and laparoscopy offered a definitive diagnosis with no missed injuries. Postoperative complications occurred in four cases (three following laparotomy and one following laparoscopy, P = 0.326). The average recovery period for bowel function, vital appearance, and food re-intake after laparoscopy was 10.36 ± 4.72 h, 14.91 ± 3.14 h, and 15.00 ± 7.11 h, respectively. All of these were significantly shorter than after laparotomy (21.27 ± 10.17 h, P = 0.004; 27.82 ± 9.61 h, P < 0.001; and 24.55 ± 9.72 h, respectively, P = 0.016). CONCLUSION: Compared with laparotomy, laparoscopy offers equivalent efficacy for diagnosing and treating SBIs, and reduces postoperative complications as well as recovery period.

ABSTRACT

OBJECTIVE/HYPOTHESIS: The role of central neck dissection (CND) remains controversial in differentiated thyroid cancer (DTC). STUDY DESIGN: Systematic review and meta-analysis. METHODS: A systematic review and meta-analysis focusing on surgical morbidities and locoregional recurrence after total thyroidectomy (TT) with CND versus TT alone was performed. RESULTS: Sixteen trials were analyzed. There was no increased risk of recurrent laryngeal nerve (RLN) injury (temporary or permanent), permanent hypocalcemia, or locoregional recurrence when CND was performed in addition to TT. Postoperative temporary hypocalcemia was more common after TT with CND than after TT alone. CONCLUSIONS: TT alone results in less surgical morbidity in the immediate postoperative period and an identical locoregional recurrence rate compared with TT plus CND.

ABSTRACT

BACKGROUND: To present our experience of vaginal reconstruction with the use of a pedicled ileum segment and laparoscope assistance, and to analyze its complications and long-term anatomic and functional results. METHODS: The abdominal and perineal approaches were performed simultaneously with the patient in a special position. Under the guidance of laparoscopy, the target ileal segment was harvested and transposed down to the perineum through an artificial tunnel between the bladder and the rectum. A silicon vaginal tutor was introduced into the vaginal cavity and maintained all day long for 2-3 months. The complications and the anatomical and functional results were summarized and analyzed. RESULTS: From February 2002 to June 2010, 82 patients underwent laparoscope-assisted total vaginal reconstruction with a pedicled ileum segment at our department. Complications developed in 16 of 82 patients, including rectum and/or bladder injury during operation, acute renal failure, delayed healing of the ileocutaneous anastomosis, introital stenosis, and partial or complete intestinal obstruction. The abdominal cutaneous scar was acceptable after the surgery. The vulva was not altered, which was especially significant for patients with congenital vaginal atresia. The neovagina was patent, soft, moist, and flexible. The mean width and depth of the neovagina at the latest postoperative visit measured 3.2 and 15 cm, respectively. CONCLUSIONS: The favorable long-term anatomical and functional results demonstrate that our technique is ideal for patients with congenital vaginal atresia or patients who need secondary vaginal reconstruction. For the primary male-to-female transsexuals or hermaphrodites, it can be an alternative method for vaginal construction.

ABSTRACT

OBJECTIVE: It is extremely important to establish sufficient exposure and room for manipulation during endoscopic thyroidectomy. To solve this problem, the authors have developed a new technique for retraction of the strap muscles perfected during 500 cases of breast-approach endoscopic thyroidectomy. METHODS: The new technique encompasses the use of 3 styles of retractor: the suture retractor, the button retractor, and the adjustable button retractor. These retractors are all easy to make and are all useful in different situations. CONCLUSIONS: The new technique is a safe and cost-effective method. It reduces the operation time required to obtain good exposure without transecting the strap muscles. In addition, it is minimally invasive and confers cosmetic benefits.

ABSTRACT

The first cases of video-assisted thyroidectomy and scarless endoscopic thyroidectomy were reported in China in 2001 and 2002, respectively. Breast approach endoscopic thyroidectomy (BAET) has become the most popular procedure for treating thyroid disease in China. Chinese doctors did not pioneer this approach, but contributed toward improvement in technical details such as incision selection, creation of a working space, suture exposure, and control of intraoperative bleeding. Relatively large series confirmed that BAET is a safe procedure but has a long learning curve that can be overcome with training. Surgical stress was not significantly increased despite the larger subcutaneous dissection. BAET to treat malignancy is feasible, but larger series and longer follow-up are warranted before its widespread acceptance.

ABSTRACT

BACKGROUND: By comparison with the conventional surgical approach to thyroidectomy, scarless (in the neck) endoscopic thyroidectomy (SET) has a superior cosmetic result but a very long learning curve. The objective of the present study was to compare surgical outcomes of SET performed by an experienced surgeon with the outcomes of conventional thyroidectomy. METHOD: Enrolled in this study were 25 patients who underwent SET and 18 who underwent conventional surgery. Differences in size of tumor, length of incision, duration of operation, volume of blood loss, pathological findings, postoperative pain, complications, and cosmetic result were investigated. RESULTS: The two groups were well matched. The total length of incisions and volume of blood loss of SET were significantly lower than those of conventional surgery. In addition to the superior cosmetic result, postoperative pain was significantly less severe and rates of hypesthesia or paresthesia and discomfort while swallowing were significantly lower in the endoscopy group. CONCLUSIONS: In experienced hands, SET offers more benefits than the conventional approach, including less postoperative pain and discomfort and a better cosmetic outcome.

ABSTRACT

We evaluated the invasiveness of breast approach endoscopic thyroidectomy (BAET) carried out by surgeon very experienced in this procedure. Twenty-four patients who underwent BAET and 19 patients who underwent conventional thyroidectomy were the study population. Postoperative pain was assessed by a visual analog scale (VAS). The values 2, 12, and 24 h after surgery were significantly lower in the BAET group than those in the conventional group. Serum IL-6 and CRP levels were measured by an ELISA preoperatively and at 2, 12, 24 and 48 h after operation. Their values increased significantly after both procedures when compared to preoperative levels with significant differences between the two groups detected at the 24-hour and 48-hour time points. Subjective and objective evidence supported the notion that BAET could become a minimally invasive procedure if the surgeon gained sufficient experience.

ABSTRACT

AIM: To demonstrate the optimal surgical procedure for gastroesophageal reflux disease. METHODS: The electronic databases of Medline, Elsevier, Springerlink and Embase over the last 16 years were searched. All clinical trials involved in the outcomes of laparoscopic Nissen fundoplication (LNF) and laparoscopic Toupet fundoplication (LTF) were identified. The data of assessment in benefits and adverse results of LNF and LTF were extracted and compared using meta-analysis. RESULTS: We ultimately identified a total of 32 references reporting nine randomized controlled trials, eight prospective cohort trials and 15 retrospective trials. These studies reported a total of 6236 patients, of whom 4252 (68.18%) underwent LNF and 1984 (31.82%) underwent LTF. There were no differences between LNF and LTF in patients' satisfaction, perioperative complications, postoperative heartburn, reflux recurrence and re-operation. Both LNF and LTF enhanced the function of lower esophageal sphincter and improved esophagitis. The postoperative dysphagia, gas-bloating syndrome, inability to belch and the need for dilatation after LNF were more common than after LTF. Subgroup analyses showed that dysphagia after LNF and LTF was similar in patients with normal esophageal peristalsis (EP), but occurred more frequently in patients with weak EP after LNF than after LTF. Furthermore, patients with normal EP after LNF still had a higher risk of developing dysphagia than did patients with abnormal EP after LTF. CONCLUSION: Compared with LNF, LTF offers equivalent symptom relief and reduces adverse results.

ABSTRACT

The development of laparoscopic surgery has generated the new field of study, laparoscopic anatomy. This article reviews the reported literature on laparoscopic anatomy and explores how it has evolved along with advances in abdominal surgery. In addition, the principal concerns in current laparoscopic anatomy research are discussed, including: (1) types of special adjacent anatomical structures; and (2) special surgical planes and anatomical landmarks. Understanding of systematic laparoscopic anatomy can provide the junior surgeons a clear procedural approach, and would benefit laparoscopic surgeons in training.

ABSTRACT

BACKGROUND: Breast approach endoscopic thyroidectomy (BAET) allows surgeons to remove a thyroid tumor from a remote site while providing a scarless cosmetic appearance in the neck. However, seroma formation after subcutaneous dissection could lead to flap detachment, incision dehiscence, and wound infection. Chronic formation of seromas could substantially compromise the esthetic outcome of BAET. We evaluated the prevalence, risk factors, and treatments of seroma after BAET. METHODS: A total of 344 patients who underwent BAET between 2001 and 2008 at our institution were recruited; data were collected prospectively. The characteristics and outcomes of patients who developed seromas were compared with those of patients who did not. Regression analysis was used to identify the independent risk factors for seroma formation. The frequency and volume of aspirations were noted until the seroma went into remission. RESULTS: The overall postoperative prevalence of seroma formation was 2.9%. There was a significant difference in seroma formation based on age, hypertension, body mass index (BMI), and area of subcutaneous dissection space (ASDS). Percutaneous aspiration alone or combined with external compression was extremely effective. The frequency and total volume of aspirations were 1-7 and 6-120 ml, respectively. As a result of prolonged seroma formation, one patient developed an expanding pseudo-bursa that created a tumor-like effect in the anterior chest wall. CONCLUSIONS: Seroma formation was an uncommon minor complication after BAET. Four independent etiologic factors could predispose patients to postoperative seroma formation. Percutaneous aspiration appeared to be very effective. Prolonged seroma formation followed by development of a pseudo-bursa could be very problematic and could substantially impair the esthetic effect of BAET.

ABSTRACT

OBJECTIVE: To investigate the clinical significance of the operation score system for endoscopic thyroidectomy. METHODS: An operation score system based on 6 important procedure skills of endoscopic thyroidectomy was established. And a retrospective study of the first 300 consecutive patients underwent endoscopic thyroidectomy from July 2001 to December 2007 by a single surgeon was performed. The patients was divided into 10 consecutive groups chronologically, each comprising 30 cases. RESULTS: The mean operation score of all the patients was 6.0 and the mean operation time was 98.1 min. There were significant differences in the mean operation score, every skill score and the mean operation time among the 10 groups. In the consecutive two groups comparison, significant differences in the operation scores were observed between group 2 and 3 (P < 0.05) and between group 5 and 6 (P < 0.05). CONCLUSION: The operation score system for endoscopy thyroidectomy is a useful method to judge the proficiency and the stability of the operation.

ABSTRACT

BACKGROUND: Endoscopic thyroidectomy has been known to surgeons for only 20 years. Related studies still are needed to make up for the deficiency of clinical experience. Research on the learning curve for the endoscopic thyroidectomy could be the method for investigating the operation experience. METHODS: This retrospective study investigated 300 consecutive patients who underwent endoscopic thyroidectomy by a single endoscopist during the past 7 years. The study population was equally divided into 10 groups chronologically. Pearson's chi-square test and one-way analysis of variance were used to compare differences in the demographic data, operative time, operation score system, and follow-up data. RESULTS: The mean operative time was 98.07 min. The mean operation score was 6.00, and the rate of conversion to open surgery was 3.7%. There were no differences in demographic data or complications among the 10 groups. Subcutaneous edema occurred in five cases and transient recurrent laryngeal nerve palsy in five cases. There were significant differences in the mean operative time (p < 0.01) and the mean operation score (p < 0.01) among the 10 groups. Comparison of two neighboring groups showed differences in both operative time (p < 0.05) and operation score (p < 0.01) between groups 2 and 3 and in operation score between groups 5 and 6 (p < 0.05). CONCLUSIONS: The first 60 cases constitute the early stage of the learning curve for endoscopic thyroidectomy. The proficiency and stability of the operation reach the advanced level after 150 cases.

ABSTRACT

OBJECTIVE: To investigate the possibility of Laparoscopic reconstruction of vagina using pedicled ileal autograft and provide a new procedure of colpopoiesis. METHODS: The abdominal and perineal approaches were performed simultaneously under a sufficiently deep general anaesthesia. Laparoscopically, a 15-18 cm segment of the ileum on its vascular pedicle, ileal branches of the superior mesenteric artery and its concomitant veins, was selected and isolated for transplantation using ultrasonically-powered instruments. The distal of the transferred ileal segment was 15cm apart from the ileocecal junction. The ileum continuity was restored immediately by end-to-end anastomosis and the distal oral of the transplant was closed using a curved intraluminal stapler. Meanwhile, a neovaginal tract was completed to dissect from the perineum into the peritoneum and the tract widened laterally. Then the ileum transplant was reversed to reach the perineum through the peritoneal incision at the top of the neovaginal tract without subjecting the mesenteric neurovascular pedicle to undue tension and subsequent necrosis. The oral edge of the ileum transplant was sutured to the perineal skin. RESULTS: Followed up for over 1-53 months postoperatively, 36 patients who received laparoscopic vaginoplasty by transferring ileal segment flaps got satisfactory neovaginal function similar to a normal vagina with mucus and moistness. CONCLUSIONS: The advantages of using a laparoscopic ileum colpopoiesis are that (1) satisfactory neovaginal function similar to a normal vagina with mucus and moistness, (2) no disturbance of bowel function, (minimal scarring in abdominal wall and less secondary deformity in perineum and (3) no need for frequent dilation or stent wearing to the reconstructed vagina. And so laparoscopic vaginoplasty was a preferable alternative of vaginoplasty.
