Vaginal cuff dehiscence after total hysterectomy or total cystectomy had been increasing since laparoscopic or robotic surgery became a common surgery among gynecologists and urologists. A 52-yearold woman underwent laparoscopic radical total cystectomy for muscle invasive bladder carcinoma at Rakuwakai Otowa Hospital. She was emergently admitted with a fist-sized lump protruding from her vagina four months after surgery. Physical examination and her past history on admission disclosed vaginal cuff dehiscence after cystectomy. Computed tomographic scan and magnetic resonance imaging showed no bowel evisceration in the lump. We confirmed that the content of lump was peritoneal tissue and removed it by laparoscopic surgery. Simultaneously, we repaired the vaginal cuff dehiscence with a gracilis myocutaneous flap. There was no subsequent recurrence of vaginal dehiscence or bladder carcinoma in one-year follow-up.

UNASSIGNED: Patients requiring surgery for secondary peritonitis demonstrate a significantly increased risk for incisional surgical site infection. This study aimed to evaluate the efficacy of subcutaneous wound drain post-laparotomy for contaminated surgical wounds.
UNASSIGNED: This was a prospective comparative hospital-based study.
UNASSIGNED: Patients who had surgery for secondary peritonitis in Irrua Specialist Teaching Hospital were studied.
UNASSIGNED: Fifty patients aged 16 years and above who presented with secondary peritonitis.
UNASSIGNED: Patients who met the inclusion criteria were randomized into two equal groups. Group A had a suction drain placed in the subcutaneous space after laparotomy while Group B did not.
UNASSIGNED: Development of incisional surgical site infection, wound dehiscence, and duration of post-operative hospital stay.
UNASSIGNED: The incidence of incisional surgical site infection was significantly less in Group A (20%) than in Group B (68%). There was no case of wound dehiscence in Group A as against 3 (12%) in Group B. The difference was not statistically significant. The mean duration of hospital stay was significantly less with subcutaneous suction drain (8.96+2.81 Vs 14.04+8.05; p = 0.005).
UNASSIGNED: Subcutaneous suction drainage is beneficial in abdominal wall closure in cases of peritonitis as it significantly reduces the incidence of incisional surgical site infection and the duration of postoperative hospital stay. The reduction in surgical wound dehiscence observed in this study was, however, not statistically significant.
UNASSIGNED: None declared.

Transvaginal organ prolapse, such as small bowel evisceration, is a rare complication after radical cystectomy (RC) in female patients with invasive bladder cancer, However, it often requires emergency surgical repair. Here, we describe our experience with such a case and a review of similar previously reported cases, along with evaluation of the risk factors. We also propose a vaginal reconstruction technique to prevent this complication during robot-assisted laparoscopic radical cystectomy (RARC). A total of 178 patients who underwent laparoscopic radical cystectomy (LRC) or RARC were enrolled, 34 of whom (19%) were female. One of the 34 female patients had transvaginal small bowel evisceration after RARC. We evaluated our case and six such previously reported cases, to determine vaginal reconstruction techniques during RARC to prevent this complication postoperatively. Median age of these cases was 73 (51-80) years, and all patients were postmenopausal. The median time to small bowel evisceration was 14 (6-120) weeks postoperatively. In addition, we changed the methods of the vaginal reconstruction technique during RARC from the conventional side-to-side closure technique to the improved caudal-to-cephalad closure technique. Since implementing this change, we have not experienced any cases of vaginal vault dehiscence or organ prolapse. Transvaginal small bowel evisceration after RC can easily become severe. Therefore, all possible preventive measures should be taken during RARC. We believe that our vaginal reconstruction techniques might reduce the risk of developing this complication.

OBJECTIVE: This study aimed to assess membrane use with a bone substitute graft for guided bone regeneration (GBR) in experimental dehiscence defects.
METHODS: Maxillary second incisors (I2) in 9 dogs were extracted. Six weeks later, implants were inserted and experimental dehiscence defects (5 × 3 mm) created on the buccal aspect. The defects and surrounding bone were grafted with deproteinized bovine bone mineral. One side (test) was covered with a resorbable collagen membrane whereas the contralateral side (control) was not. After 6 weeks, histomorphometrical analysis was performed to evaluate: (a) first bone-to-implant contact (fBIC), (b) buccal bone thickness at 1 mm increments from implant shoulder, (c) regenerated area (RA), (d) area and percentages of new bone (B), bone substitute (BS) and mineralized tissue (MT).
RESULTS: The histological appearance was similar between test and control sites. At central and lateral sections, there were no differences between groups for fBIC, buccal bone thickness, RA, BS, B, %B, MT and %MT. At central sections, membrane use favoured more %BS and %MT (p = 0.052). There was significantly more B, %B and MT at lateral compared to central sections.
CONCLUSIONS: Membrane use tended to retain more bone substitute, but had no effect on new bone ingrowth. Lateral sections showed significantly more bone ingrowth and mineralized tissue compared to central sections, confirming that new bone ingrowth takes place mainly from the lateral walls of the defect.
CONCLUSIONS: Preclinical research to clarify the dynamics of bone regeneration in GBR procedures is relevant in clinical practice.

BACKGROUND Uterine dehiscence, an infrequent event often mistaken for uterine rupture, is rarely linked to post-cesarean section procedures and can result in severe complications, notably puerperal sepsis. In this report, we present a case that exemplifies the onset of puerperal sepsis and the emergence of intra-abdominal abscesses attributed to uterine dehiscence following a lower segment cesarean section (LSCS). CASE REPORT Our patient, a 28-year-old woman in her third pregnancy, underwent LSCS 1 week earlier. Subsequently, she returned to the hospital with lower abdominal pains, fever, and malodorous vaginal discharge. Computed tomography (CT) scan of whole abdomen verified uterine dehiscence and pus collection at the subhepatic region and right paracolic gutter. After referral to a specialized hospital, laboratory findings indicated an elevated white blood cell count and alkaline phosphatase levels, and coagulation abnormalities. She underwent an exploratory laparotomy, which unveiled uterine dehiscence, abscesses, and adhesions, necessitating a total abdominal hysterectomy and abdominal toileting. Pus culture analysis identified the presence of E. coli, which was susceptible to ampicillin/sulbactam. Complications were encountered after surgery, including wound dehiscence and pus re-accumulation. Successful management involved vacuum dressings and percutaneous drainage. Eventually, her condition improved and she was discharged, without additional complications. CONCLUSIONS This report underscores the importance of considering cesarean scar dehiscence as a diagnosis in women with previous cesarean deliveries who present during subsequent pregnancies with symptoms such as abdominal pain or abdominal sepsis. Diagnostic tools, such as CT, play pivotal roles, and the timely performance of an exploratory laparotomy is paramount when suspicion arises.

Wound dehiscence is a common complication after secondary alveolar bone grafting (SABG), leading to unfavourable surgical outcomes. Studies have shown that autologous platelet concentrates (APC) may enhance wound healing and improve outcomes. Therefore, this review aimed to evaluate in patients with alveolar clefts, whether using APC and iliac crest bone graft can mitigate the likelihood of wound dehiscence formation compared with those who underwent iliac bone grafting only following SABG. A comprehensive literature search was conducted using various electronic databases, including PubMed, Embase, Scopus, Web of Science, EBSCOhost, Ovid MEDLINE, LILACS, Cochrane Library, and grey literature, to include studies until July 31, 2023, without any restriction to language and time of publication. Only randomized (RCT) and controlled (CCT) clinical trials were included. Two independent reviewers screened the studies based on the predefined criteria, after which a qualitative and quantitative analysis was conducted. The search yielded 821 studies, of which seven were deemed eligible for systematic review. The risk of bias assessment done using \"The Cochrane collaboration tool for risk of bias assessment\" for six RCTs and the \"Risk of Bias in Non-randomized Studies - of Interventions\" for one CCT revealed a moderate to high risk of bias. The meta-analysis of five studies showed that the overall risk of developing wound dehiscence was lower in the APC group (RR = 0.33; 95% CI: 0.16, 0.71; p = 0.005; χ2 = 0.82; I2 = 0%). Subgroup analyses based on study design further supported these findings. Although the adjuvant use of APC for alveolar cleft reconstruction reduces the risk of wound dehiscence, more studies with increased scientific rigour and fewer confounding variables are warranted.

OBJECTIVE: Anterior palatal reconstruction using vomer flaps has been described during primary cleft lip repair. In this procedure, the mucoperiosteal tissue of the vomer is elevated to reconstruct the nasal mucosa overlying the cleft of the hard palate. Here the authors, evaluate the efficacy of a technique in which a superiorly based vomer flap is sutured to the lateral nasal mucosa. The authors assess vomer flap dehiscence rates and compare the likelihood of fistula development in this cohort to patients who underwent palatoplasty without vomer flap reconstruction.
METHODS: A retrospective chart review was conducted of all palatoplasties performed by the senior author at an academic institution during a 7-year period. Medical records were reviewed for demographic variables, operative characteristics, and postoperative complications up to 1 year following surgery. Logistic regression analysis was conducted to assess the effects of vomer flap reconstruction on fistula formation, adjusting for age and sex.
RESULTS: Fifty-eight (N=58) patients met the inclusion criteria. Of these, 38 patients (control group) underwent cleft palate reconstruction without previous vomer flap placement. The remaining 20 patients underwent cleft lip repair with vomer flap reconstruction before palatoplasty (vomer flap group). When bilateral cases were counted independently, 25 total vomer flap reconstructions were performed. Seventeen of these 25 vomer flap reconstructions (68%) were completely dehisced by the time of cleft palate repair. In the vomer flap group, 3 of the 20 patients (15%) developed fistulas in the anterior hard palate following the subsequent palatoplasty procedure. In the control group, only 1 of the 38 patients (2.6%) developed a fistula in the anterior hard palate. There was no significant association between cohorts and the development of anterior hard palate fistulas [odds ratio=10.88, 95% confidence interval (0.99-297.77) P =0.07], although analysis was limited by low statistical power due to the small sample size.
CONCLUSIONS: In our patient population, anterior palatal reconstruction using a superiorly based vomer flap technique was associated with complete dehiscence in 68% of cases. Fistula formation in the anterior hard palate was also proportionately higher following initial vomer flap reconstruction (15% versus 2.6%). These results prompted the senior author to adjust his surgical technique to 1 in which the vomer flap overlaps the oral mucosa. While follow-up from these adjusted vomer flap reconstruction cases remains ongoing, early evidence suggests a reduced requirement for surgical revision following implementation of the modified technique.

Objective: To investigate the application effects of armor chest straps in patients with sternal dehiscence after repair surgery. Methods: This study was a retrospective cohort study. The 11 patients who were admitted to the First Affiliated Hospital of Air Force Medical University (hereinafter referred to as the hospital) from March 2020 to March 2021 and used conventional chest straps after sternal dehiscence repair surgery were included in conventional chest strap group. The 12 patients who were admitted to the hospital from April 2021 to March 2022 and used armor chest straps after sternal dehiscence repair surgery were included in armor chest strap group. A special team for sternal dehiscence repair was set up, and the nurses in charge in the team instructed the patients in 2 groups on the correct abdominal breathing method, and the members of the surgical team performed the personalized surgery and wore the corresponding chest straps for the patients in 2 groups. The abdominal breathing frequency and chest breathing frequency on the first day after surgery were recorded. The pain intensity at 6, 24, 48, and 72 h after surgery was self-rated by the patients using numerical rating scale. The time of the first active cough and the time of wound healing after surgery were recorded. At postoperative suture removal, the cutting length of sutures induced by respiratory exercise was recorded. Whether there were complications such as redness, swelling, and exudation in flaps within 2 weeks after surgery were recorded, whether there were complications such as wound dehiscence or infection during follow-up of 3-12 months were recorded, and the incidence proportion of postoperative complications was calculated. At 6 months after surgery, the patients\' scar status was evaluated by the Vancouver scar scale. Results: The abdominal breathing frequency of patients in armor chest strap group was (16.3±1.2) times/min on the first day after surgery, which was significantly higher than (5.3±1.4) times/min in conventional chest strap group (t=20.00, P<0.05), and the chest breath-ing frequency was (1.2±0.8) times/min, which was significantly lower than (12.4±1.5) times/min in conventional chest strap group (t=22.36, P<0.05). The pain intensity scores of patients in armor chest strap group at 6, 24, 48, and 72 h after surgery were significantly lower than those in conventional chest strap group (with t values of 15.07, 14.70, 13.66, and 11.03, respectively, P<0.05). The time of the first active cough and the time of wound healing after surgery of patients in armor chest strap group were significantly sooner than those in conventional chest strap group (with t values of 5.51 and 8.90, respectively, P<0.05). At postoperative suture removal, the cutting length of sutures induced by respiratory exercise of patients in conventional chest strap group was 2.0 (0, 5.0) mm, which was significantly longer than 2.0 (1.0, 2.0) mm in armor chest strap group (Z=4.10, P<0.05). There was no statistically significant difference in the incidence proportion of postoperative complications of patients between the 2 groups (P>0.05). At 6 months after surgery, the scar score of patients in armor chest strap group was 4.1±1.4, which was significantly lower than 5.6±1.4 in conventional chest strap group (t=2.71, P<0.05). Conclusions: The application of armor chest strap in patients with sternal dehiscence after repair surgery can increase the abdominal breathing frequency, reduce the wound cutting force, effectively relieve postoperative pain, increase the first active cough and wound healing speed, and alleviate postoperative scar proliferation, achieving good application effect.

OBJECTIVE: We aimed to evaluate the outcomes, complication rates, and complication types of different labiaplasty techniques.
METHODS: In this cross-sectional retrospective study, a total of 2,594 patients who underwent surgery owing to hypertrophy or asymmetry of the labium minus were retrospectively analyzed. Data were collected by individual interviews with 43 experts from different centers. The patients were between 18 and 50 years of age. During the interview information about the presence and nature of complications, and about concomitant or revision surgeries, were gathered. The surgeons who performed these surgeries were also questioned about their training and surgical experience.
RESULTS: The most frequently observed complication was complete dehiscence, accounting for 29% of all complications. Complete dehiscence was most commonly seen after wedge resection (16 cases). The second most common complication was labium majus hematoma, accounting for 12.5% of all cases. Among the labiaplasty techniques, wedge resection had the highest complication rate at 3% (26 cases out of 753 patients). This was followed by composite labiaplasty at 1.2% (5 cases out of 395 patients), Z-plasty at 0.8% (1 case out of 123 patients), and trimming labiaplasty at 0.5% (7 cases out of 1,323 patients).
CONCLUSIONS: Considering the heterogeneity and low quality of the existing studies on this subject, this study provides valuable information for surgeons practicing in this field. However, further research is clearly warranted as female genital aesthetic procedures are being performed with a steadily increasing trend.
