Contemporary role of the plastic and reconstructive surgeon in the outcome of female peripelvic defects after oncologic extirpation.

Reconstruction of female oncologic peripelvic defects is challenging due to complex anatomy, neoadjuvant chemoradiation, operative resection margins, and wound healing risks. Functional restoration requires thoughtful management focused on defect reconstruction and patient-reported outcomes. A retrospective chart review of peripelvic reconstruction in female patients at MD Anderson Cancer Center from 2016 to 2023. Data collected included the patient'scomorbidities, tumor characteristics, and reconstructive details. Complications were classified as nonoperative or operative within 30 days. Patient outcomes included hernia rates, sexual activity, and revision needs. In the study period, 164 patients underwent peripelvic defect reconstruction. Most had colorectal (57%), anal (17%), or gynecologic malignancies (10%). 83% had prior radiation. 33.3% had Class II or III obesity. The most common resection was open colorectal resection with partial vaginectomy (66%). Pedicled flaps (93%) were frequently used, mainly vertical rectus abdominis muscle (65%) and gracilis (11%). For multi-visceral resections, abdominal-based flaps were used in 95% of open casesand thigh-based flaps in 88.9% of robotic cases. 51% had formal abdominal wall repair. Complications occurred in 47%, with 9.1% needing surgery. Postoperative hernias were reported in 4.9%, with 3% requiring repair. Approximately 11% reported being sexually active at the last follow-up. Of those instructed on vaginal dilator therapy (42%), 24.6% were sexually active. Peri-pelvic soft tissue reconstruction in the oncologic population is safe. Operative complications and hernia rates are low. In robotic surgery, thigh-based flaps are increasingly used to reconstruct the peripelvic region. Return to sexual activity is higher in patients when given dilator therapy instruction.

A single-centre, retrospective study of incisional hernia repair outcomes post kidney transplantation.

Incisional hernias (IH) after kidney transplantation (KTx) can cause significant morbidity in kidney transplant recipients (KTR). We aimed to report the outcomes of surgical repair of IH in KTR from our centre. We retrospectively analysed all the IH repairs in KTR from May 2018 to May 2023. We documented pre-transplant baseline characteristics, peri- and post-KTx events and outcomes and post-IH repair complications. We also documented length of stay, survival, and hernia recurrence post-IH repair. We performed 35 incisional hernia repairs in 34 KTR from May 2018 to May 2023 with an overall incidence of 1.63% symptomatic IH. Mean patient age was 56.7 ± 10.1 years and mean body mass index (BMI) 29.7 ± 6.49kg/m2. A history of previous hernia operation and open abdominal operations was present in 11.4% and 22.9% of the population, respectively. The types of repairs performed were primary (5.7%), onlay (62.9%), inlay (2.9%) and retromuscular sublay (28.6%). Mean hernia neck size was 8.9 ± 5.6cm. After IH repair, there was no perioperative mortality with an average 5.5 ± 3.9 days of length of stay. There were seven episodes (20%) of IH recurrence. There was a 6% of superficial wound dehiscence rate and a 3% of surgical site infection. Pearson's correlation test revealed that post-operative hernia recurrence was not related with neck size, post-transplant complications or pre- and post-transplant characteristics, as well as post-transplant outcome. The recurrence rate in our cohort was 20%. Known risk factors for IH in KTR as well as post-KTx events were not correlated with hernia recurrence or other post-hernia repair complications.

Introduction. Postoperative hernias occur in 10–15% of patients. Considering the increase in the incidence of complications with the number of operations it is crucial to choose the optimal surgical technique in order to control the complications rate. This literature review summarizes previous studies on the treatment of postoperative hernias with mesh, comparing complication and recurrence rates according to surgical technique and mesh position. Methods. A thorough search was conducted on the PubMed database to retrieve literature on recurrence, chronic pain, haematoma, seroma, and surgical site infections rates. The results were meticulously summarised and used to confidently compare open and laparoscopic surgical techniques, as well as “sublay” and “onlay/inlay” mesh positions in more than 5-year follow-up. Results. The analysis was conducted on five publications that met the selection criteria. The results showed that laparoscopically treated hernias had lower recurrence and chronic pain rates, but more frequent haematomas. The presence of wound infections, BMI >30, treatment of recurrent postoperative hernias, multiple fascia lesions, enterotomy, larger abdominal wall defect and longer operative time were observed to be associated with higher recurrence rates. The position of the sublay mesh is associated with less frequent seromas, surgical infections, and recurrence compared to the onlay/inlay position. Studies have reported the superiority of large-pore lightweight polypropylene multifilament mesh over the same heavyweight mesh in managing postoperative hernias. Lightweight mesh is linked to a lower risk of hernia recurrence and higher compliance with the abdominal wall. Conclusion. Laparoscopic surgery is associated with lower rates of recurrence and chronic pain, but a higher frequency of haematomas. The sublay mesh position is associated with lower rates of seromas, surgical infections, and recurrence.

Matching males and females undergoing non mesh primary unilateral inguinal hernia repair: evaluating sex differences in preoperative and acute postoperative pain.

The objective was to compare pain and related psychological factors during the preoperative and acute postoperative period between male and female patients, who underwent non mesh primary unilateral inguinal hernia repair. After ethics approval, informed consent was obtained, and data were collected. Male and female participants were compared by manually matching one-to-one on 10 variables. Descriptive statistics (mean ± standard deviation and frequency) as well as numerical rating scales from 0 to 10 were used. Comparison tests were performed using Chi-square or Fisher's Exact test for categorical data and independent samples t-test or non-parametric equivalent tests for numerical scores. p < 0.05 is reported as statistically significant. To control type I error, Bonferroni correction was used. 72 participants with 36 matched pairs were included. Sex differences were found for operation length (p = .006), side of operation (p = .002), and hernia type (p = .013). Significant differences between the sexes were not found at the preoperative or postoperative time for resilience, pain interference or pain severity related measures, postoperative hernia pain incidence, pain catastrophizing, depression and anxiety symptoms, or return to normal activities. When controlling for known confounders and using a conservative Type I error rate, pain and related factors between the sexes did not differ significantly.

THE ROLE OF PATIENT SCREENING AND RISK STRATIFICATION IN THE PREOPERATIVE PREPARATION OF PATIENTS WITH ANTERIOR ABDOMINAL WALL HERNIAS

Introduction. Lifestyle, poor physical condition, bad habits, malnutrition and adverse psychological factors reduce the body's resistance to overcome the physiological stress of surgery. Abdominal wall hernia repair is one of the most common surgical operations. A high body mass index, smoking, diabetes and immunosuppression are risk factors for the development of postoperative hernia, and in the case of its surgical correction, these factors significantly worsen the perioperative prognosis. Assessing the risk of serious complications and death during the perioperative period is crucial for the patient. Aim. To assess the role and necessity of patient screening and risk stratification in the complex of preoperative preparation of patients with anterior abdominal wall hernias. Materials and methods. In the research took part 91 patients who underwent surgical treatment of abdominal wall hernias. They were divided into 3 groups according to the type of anesthesia (general, neuraxial and fascial blocks of the abdominal wall). The analysis was carried out according to comorbidity, the presence of lifestyle risks, the risk of cardiovascular complications (LI index), the risk of anesthesia according to the ASA (American Society of Anesthesiologist's) scale and the risk of thromboembolic complications according to the Caprini scale, factors that affect the frequency postoperative nausea, vomiting and their prevention. Results and discussions. It was determined that the most common concomitant pathology in patients of 1, 2 and 3 study groups was arterial hypertension. Ischemic heart disease was most often observed in patients of group 3. Patients with a history of acute coronary syndrome dominated in the 3rd observation group. Patients were also noted to have diabetes mellitus, chronic obstructive pulmonary disease, and a history of impaired cerebral circulation. It was determined that many patients in the studied groups did not have additional risk factors, but all of them smoked and were overweight. Many patients had anesthetic risk according to ASA II or III. Patients received combined prophylaxis of postoperative nausea and vomiting. Conclusions. All groups were dominated by patients with an average and high risk of developing perioperative complications. Careful examination, identification of potential risk factors related to comorbidities and lifestyle are important to reduce the risk of complications in patients with abdominal wall hernias in the complex of preoperative preparation. Patients with a high risk of developing perioperative complications are recommended to choose neuraxial or regional anesthesia to prevent the development of postoperative complications.

Evaluating postoperative hernia incidence and risk factors following pelvic exenteration

Pelvic exenteration (PE) is a technically challenging surgical procedure. More recently, quality of life and survivorship following PEs are being increasingly acknowledged as important patient outcomes. This includes evaluating major long-term complications such as hernias, defined as the protrusion of internal organs through a facial defect (The PelvEx Collaborative in Br J Surg 109:1251–1263, 2022), for which there is currently limited literature. The aim of this paper is to ascertain the incidence and risk factors for postoperative hernia formation among our PE cohort managed at a quaternary centre.MethodA retrospective cohort study examining hernia formation following PE for locally advanced rectal carcinoma and locally recurrent rectal carcinoma between June 2010 and August 2022 at a quaternary cancer centre was performed. Baseline data evaluating patient characteristics, surgical techniques and outcomes was collated among a PE cohort of 243 patients. Postoperative hernia incidence was evaluated via independent radiological screening and clinical examination.ResultsA total of 79 patients (32.5%) were identified as having developed a hernia. Expectantly, those undergoing flap reconstruction had a lower incidence of postoperative hernias. Of the 79 patients who developed postoperative hernias, 16.5% reported symptoms with the most common symptom reported being pain. Reintervention was required in 18 patients (23%), all of which were operative.ConclusionThis study found over one-third of PE patients developed a hernia postoperatively. This paper highlights the importance of careful perioperative planning and optimization of patients to minimize morbidity.

Comparison of Outcome of SAC Ligation Versus No SAC Ligation in Pediatric Patients Undergoing Inguinal Orchidopexy for Incompletely Descended Palpable Testes: A Randomized Control Trial

Background and Objective: The case of undescended Testis (UDT) is one of the most common condition presented to a pediatric surgeon. The standard procedure to rectify UDT is known as Orchidopexy. The main objective of this study is to examine and compare the results of orchidopexy surgeries conducted with or without sac ligation in palpable undescended testis of pediatric patients.Methods: This randomized controlled trial was done over a period of 12 months (July 2018 to July 2019) atthe Department of Pediatric Surgery, Children's Hospital &amp; Institute of Child Health, Lahore. The selection of cases was made dependent upon fulfillment of departmental criteria and approval by ethical review committee. Consequently, 280 cases divided into two equal groups i.e. Group-A and Group-B (140 cases in each group) were shortlisted for the study after detailed scrutiny. The allotment of patient to above mentioned groups was randomized by lottery method. The patients in Group-A underwent orchidopexy with ligation of sac while the patients of Group-B were operated without sac ligated. The surgeries were performed under general anesthesia by consultant surgeons of same caliber and competence. Moreover, in order to quantify and analyze the results of surgeries parameters such as Mean Operative Time, Postoperative Manifestations and recurrence of UDT were recorded on proforma. Subsequently, SPSS version 25 statistical software was utilized for calculating the mean and standard deviation of numerical variables such as age and operative time. Additionally, the frequency and percentage of variables such as recurrent UDT were also calculated. Chi-square test was applied to recurrent UDT and development of inguinal hernia. It is highlighted that P-value ≤0.05 was taken as significant.Results: Among 140 patients of sac ligation group, 40.7% were 1-4 years old and among 140 patients of nosac ligation group, 42.9% were 1-4 years old. In sac ligation group, 60.0% patients had right undescended testis while in no sac ligation group, 67.1% patients had right undescended testis. In sac ligation group, the mean operative time was 37.81 + 8.82 minutes while in non-sac ligation group; the mean operative time was24.34 + 4.12 minutes. In sac ligation group, no patient had post-operative hernia while in non-sac ligation group, 1.4% patients had post-operative hernia (p=0.15). In sac ligation group, 1.4% patients had recurrent UDT while in non-sac ligation group, 2.1% patients had recurrence. (p= 0.65)Conclusion: Study concluded that non-sac ligation technique is more effective than sac ligation technique interms of operative time and should be preferred for patients by surgeons.Keywords: Orchidopexy, undescended testes, testicular atrophy, inguinal hernia, recurrence

Pediatric incarcerated inguinal hernia: Traditional open or laparoscopic-assisted approach?

The objective of this study was to compare the safety and efficacy of laparoscopic-assisted surgery and traditional open surgery for pediatric incarcerated inguinal hernia. A total of 58 pediatric patients with indirect incarcerated inguinal hernia between January 2014 and January 2020 were included in this study. The patients were divided into 2 groups; observational group who underwent laparoscopic-assisted surgery (n = 36), and a control group who underwent traditional open surgery (n = 22). The overall operation time, intraoperative blood loss, postoperative recovery time, length of hospital stay, occurrence of postoperative scrotal or vulvar hematomas, incidence of postoperative surgical site infection, and hernia recurrence were analyzed and compared between the 2 groups. Compared with the control group, the operation time (38.28 ± 5.90) minutes, intraoperative blood loss (1.15 ± 0.54 mL), postoperative recovery time (8.39 ± 1.42 h), and length of hospital stay (1.64 ± 0.59) were significantly lower in the observational group (P < .05). There was no incidence of scrotal or vulvar hematoma or surgical site infection in the observation group, which was significantly lower than that in the control group (P < .05). However, no statistically significant difference was found in the rate of postoperative hernia recurrence between the 2 groups (P > .05). In conclusion, laparoscopic-assisted surgery appears to be a safe and effective alternative approach to traditional open surgery for the treatment of pediatric incarcerated inguinal hernia. Its advantages include reduced trauma, faster recovery, shorter hospital stays, and fewer complications.

Modern concept of treatment of patients with ventral hernias

INTRODUCTION. The relevance of treating patients with hernias of the anterior abdominal wall is beyond doubt, since the incidence of the disease is on average 5 people per 1000, and hernioplasty itself is one of the most common operations in a general surgical hospital. However, the relapse rate remains quite high. There remains a debate about the choice of surgical option; the issues of prevention and treatment of pain syndrome, as well as tactics for managing patients with a complicated postoperative period, remain unresolved.The OBJECTIVE was to evaluate the effectiveness of the modern concept of treating patients with ventral hernias and to substantiate the principles for choosing a hernioplasty technique.METHODS AND MATERIALS. The study is based on the results of treatment of 1938 patients operated on at the Faculty Surgery Clinic named after S.P. Fedorov Military Medical Academy in the period from 2015 to 2022. Both open and endovideosurgical options for surgical interventions were performed for isolated umbilical hernias or in combination with diastasis of the rectus muscles, hernias of the white line of the abdomen, inguinal and postoperative hernias, including reduction of the volume of the abdominal cavity.RESULTS. During the study, an algorithm for the treatment of patients with ventral hernias was developed, various options for perioperative pain relief were proposed, and the tactics for treating infectious and purulent complications were substantiated.CONCLUSION. A specialized surgical hospital must perform all possible options for both traditional and endovideosurgical hernioplasty, use innovative options for pain relief in the perioperative period, and apply modern methods for diagnosing and treating postoperative complications in order to provide personalized medical care.

Results of surgical treatment of hernias of the anterior abdominal wall in patients with connective tissue dysplasia syndrome

Relevance. The problem of surgical treatment of hernias of the anterior abdominal wall remains relevant. Despite the introduction of new technologies, the results of surgical interventions cannot be considered satisfactory. The development of hernias and their relapses is facilitated by connective tissue dysplasia syndrome, which manifests as phenotypic signs, disorders of the autonomic nervous system, and morphological changes in the structure of the connective tissue.Objective. To improve the results of surgical treatment of hernias of the anterior abdominal wall in patients with connective tissue dysplasia syndrome.Materials and methods. The study was based on clinical observations and studies of 497 patients with hernias of the anterior abdominal wall. Inguinal (29 %) and postoperative hernias (21 %) predominated. In the structure of recurrent hernias, postoperative (47 %) and inguinal (42 %) hernias were more often observed. Hernioautoplasty was performed in 31 %, plastic surgery using a mesh endoprosthesis — in 54 %, endoscopic hernioplasty — in 15 % of patients. The severity of the clinical, morphological, and metabolic signs of connective tissue dysplasia syndrome was assessed. The concentration of free hydroxyproline in the blood was determined as a marker of connective tissue metabolism. The state of the autonomic nervous system was assessed using variational pulsometry. To assess the state of collagen in connective tissue, a morphological study of the aponeuroses of the muscles of the anterior abdominal wall was performed in the clinic and experiment.Results. The overall incidence of dysplasia in hernias of the anterior abdominal wall was 48 %. The highest incidence of connective tissue dysplasia was detected in recurrent hernias (70 %). Studies of the level of free hydroxyproline in abdominal hernias have shown the dependence of this marker on the degree of connective tissue dysplasia. In cases of recurrent hernias, the highest intensity of collagen biodegradation was observed. A study of the functional state of the autonomic nervous system revealed a predominance of sympathetic activity in abdominal wall hernias with an increase in the tension index by more than 4 times. An increase in the severity of dysplasia is accompanied by an increase in sympathetic activity. Histological studies in patients with abdominal hernias revealed characteristic changes in the morphological structure of the connective tissue. The average thickness, specific area, brightness of staining, and orientation of collagen fibers in postoperative and recurrent hernias were significantly different compared to the group with primary hernias (p˂0.05). Additionally, an experiment was performed on 30 laboratory animals (white rats) to determine the optimal conditions for healing of the aponeurosis of the anterior abdominal wall. The activating effect of prozerin on the process of histogenesis in the wound was revealed. Based on the results of the study, the surgical treatment of hernias was assessed depending on the type of hernioplasty and the severity of connective tissue dysplasia. It has been established that with increasing severity of dysplasia, the frequency of relapses increases by 2.2–3.4 times. With the progression of dysplasia, the frequency of relapses increased by more than twice. The use of the endoscopic hernioplasty method reduced the risk of recurrent hernias by 9 times.Conclusion. In externally localized hernias, the incidence of connective tissue dysplasia ranges from 34 % to 70 %. In patients with connective tissue dysplasia syndrome after hernia autoplasty, the frequency of hernia recurrence is 3.4 times higher. Drug correction of sympathetic activity along with alloplasty increased collagen synthesis intensity by 36 %. The choice of hernia repair method should be determined by the type of hernia, the age of the patient, and the severity of connective tissue dysplasia.

Application of the rectus abdominal muscle in reconstructive and recovery surgery of chest wall defects

Introduction. Autologous plastic tissues (muscles and greater omentum) are preferable in the reconstruction of chest wall defects in infectious and inflammatory diseases of the chest wall. Extended and deep defects can be eliminated by flaps of the rectus abdominis muscle.Aid. To study the effectiveness of various options for the use of flaps of the rectus abdominis muscle in plastic surgery of chest wall defects of infectious and inflammatory origin.Object and methods. A retrospective analysis of the results of treatment of 34 patients with osteomyelitis of the sternum and ribs of various etiologies was carried out for the period from January 1, 2012 to May 30, 2023. In 32 patients, the main diagnosis was poststernotomy mediastinitis, 2 patients had post-radiation osteomyelitis of the sternum and ribs after combined cancer treatment. mammary gland. The majority of patients (n = 29) underwent a two-stage approach to treatment using vacuum therapy at the stage of relief of acute inflammation. All patients underwent plasty with a flap of the rectus abdominis muscle. The options for surgical intervention and the outcome of treatment were studied.Results. The area of the defect to be repaired in patients ranged from 50 cm2 to 270 cm2 (mean 143.1 ± 15.3 cm2). There were no intraoperative complications in the patients. The postoperative period was complicated by various wound complications in 9 patients. Marginal necrosis of the skin part of the graft was revealed in 3 patients with full-thickness permanent graft plasty. In 3 patients, despite wound drainage, postoperative seromas were detected. Reoperations were performed in 2 patients: in one case, bleeding from the vein of the fullthickness flap was stopped, in the other case, partial necrosis of the full-thickness flap was detected, which required a second operation and revision of the flap. In 1 patient, the hematoma was emptied 3 days after the operation. The average duration of inpatient treatment of patients was 19.3 ± 2.8 days (range 17 to 38 days). There were no lethal outcomes in patients with muscle plasty with a permanent graft flap. In 1 patient, a postoperative hernia was formed in the region of the anterior abdominal wall. Recurrence of osteomyelitis of the ribs was diagnosed in 1 person 16 months after surgery.Conclusions. The rectus abdominis muscle as an isolated and full-thickness flap is the optimal plastic material for eliminating defects in both the lower part of the sternum and extensive defects in the anterior and lateral surfaces of the chest wall.

Frequency of Complications After Kidney Transplant in the Early Postoperative Period.

Complications after kidney transplant can be divided into surgical and nonsurgical. Our study investigated the incidence of postoperative complications and types of complications in a single center. We retrospectively analyzed the occurrence of postoperative complications in 220 patients who underwent kidney transplantation at the Republican Scientific Center for Emergency Medical Care (Tashkent, Republic of Uzbekistan) from January 2019 to October 2022. Among the 220 patients, various types of complications were observed in 42 cases (19.1%). Of these, 31 patients (73.8%) had surgical complications and 11 patients (26.2%) had nonsurgical complications. Surgical complications included hematoma of the postoperative wound in 8 patients (19.2%), thrombosis of the graft artery in 1 patient (2.4%), thrombosis of the venous anastomosis in 1 patient (2.4%), lymphocele of the postoperative wound in 7 patients (16.6%), wound infections 4 patients (9.5%), bleeding from the arterial anastomosis 2 patients (4.7%), bleeding from the venous anastomosis 1 patient (2.4%), kink of the venous anastomosis in 3 patients (7.2%), postoperative hernia in 2 patients (4.7%), and urological complications in the form of ureteral necrosis in 2 patients (4.7%). Nonsurgical complications included hyperacute rejection, which led to the removal of the graft, in 2 patients (4.8%), acute cellular rejection of the graft, which was successfully treated with methylprednisolone pulse therapy, in 4 patients (9.5%), delayed graft function in 1 patients (2.4%) case, and posttransplant diabetes mellitus in 4 patients (9.5%). Despite the frequency of postoperative complications, timely assistance and further monitoring of patients can lead to normal functioning of the kidney transplant, except for cases of hyperacute rejection.

The Long-Term Outcome of Abdominal Wall Defects Exomphalos &amp; Gastroschisis Retrospective Single Centre Study Children Hospital at Westmead, Sydney, Australia

Objective: To examine the natural history and detailed outcome of diagnosed cases of abdominal wall defects that admitted to The Children`s Hospital at Westmead. Methods: This was A retrospective single centre study of all cases of abdominal wall defects admitted between the 1st of October 1998 and the 1st of January 2007 to The Children`s Hospital at Westmead. The study had been conducted through a retrospective review of the neonatal, pediatric surgery records and subsequent follow-up information of all cases of Omphalocele and Gastroschisis diagnosed. Results: Ninety cases with anterior abdominal wall defects were admitted. Majority of the cases were born at Westmead Hospital. There were 25 neonates with Gastroschisis (27 females, 28 males), and 35 neonates with Exomphalos (15 females, 20 males). Eighty-one neonates had prenatal ultrasound diagnosis. Some neonates had associated congenital anomalies which results in five deaths (4 Exomphalos, 1 Gastroschisis). Post operative complications were common and the postoperative hospital stay was often lengthy. Twenty-five patients out of the ninety (15 Gastroschisis, 10 exomphalos) required further operations which were related to their primary diagnosis of Gastroschisis or Exomphalos, mostly for abdominal wall hernias. Conclusions: Long-term outcome was favourable in majority of cases with abdominal wall defects and mortality substantially happened in neonates with associated anomalies. Reoperations were necessary in those patients who had postoperative hernias.

Laparoscopic Totally Extraperitoneal Repair Using Self-gripping Polyester Mesh (ProGrip™) in Inguinal Hernia: A Retrospective Study in a Tertiary Care Hospital

Abstract Introduction: Surgical management of inguinal hernia (IH) is advanced with laparoscopy surgery, and total laparoscopic totally extraperitoneal (TEP) repair is gaining popularity. The use of self-gripping mesh (ProGrip™) further provided substantial advancements with improved postoperative outcomes and early recovery. Objectives: The objective of our study was to determine the short-term outcomes, complications, postoperative hernia recurrence, and chronic inguinal pain in laparoscopic IH. Furthermore, we assessed the factors associated with longer operative time. Subjects and Methods: We retrospectively analyzed the data of adult IH patients who had undergone TEP repair with ProGrip™ mesh. Data on demographics, hernia characteristics, operating time, surgical details, and postoperative outcomes such as infection, hernia recurrences, chronic pain, and other complications were collected and analyzed. P &lt;0.05 was considered statistically significant. Results: During January 2020 to January 2022, we collected the data of 208 patients and analyzed them. The mean age of the patients was 59.7 ± 13.1 years and 96.2% were males. Hernia was bilateral in 26% of cases and 78.8% were indirect hernias. The mean duration of surgery was 60.4 ± 8.6 min. Hernia size ≥2.5 cm was associated with significantly longer operative time. After a median follow-up of approximately 1 year, there were no postoperative complications, recurrence of hernia, or chronic inguinal pain. Conclusion: In experienced hands, laparoscopic TEP repair of IH using ProGrip™ mesh is effective and safe without significant complications or recurrences.

Simultaneous interventions in surgical gastroenterology and herniology: prediction and prevention of complications

The aim of the study - to improve the results of simultaneous surgical treatment of patients with large ventral hernias and incisional hernias W3 and concomitant surgical pathology of the abdominal organs. Material and methods. The article analyzes the results of surgical treatment of 450 patients with primary and postoperative hernias of the abdominal wall. 95 (21.1%) patients were urgently operated on. In 76 (16.9%) patients with large ventral and incisional W3 hernias, posterior separation hernioplasty was performed using TAP technology. In the presence of concomitant surgical pathology of the abdominal organs, simultaneous surgical interventions were performed. Results. In sublay and IPOM groups, 14 (3.7%) patients underwent laparoscopic sleeve resection of the stomach, 16 (4.3%) patients - laparoscopic cholecystectomy, and 4 (1.1%) patients -TAPP hernioplasty. In TAR group, 9 (11.8%) patients underwent open cholecystectomy, 12 (15.8%) - transverse abdominoplasty, 3 (3.9%) - open sleeve resection of the stomach, 2 (2.6%) - closure of the colostomy. The average duration of pain in the postoperative period was 4.5±0.9 days. The average duration of hospitalization was 9.7±1.1 days. In the postoperative period, 2 patients developed surgical site infection. There was no mortality. Conclusions. Modern simultaneous interventions in surgical gastroenterology and herniology with risk stratification of specific and nonspecific complications are an actuale social, medical and economic problem. An individual and differentiated approach to choice of simultaneous surgical intervention method taking into surgical and anesthetic risks and patients comorbidity, can reduce the percentage of postoperative complications and improve patient’s life quality.

Low Risk of Postoperative Hernia Following Single-port Robot-assisted Radical Prostatectomy: A Report From the Single-port Advanced Research Consortium (SPARC)

To evaluate the risk of postoperative hernia following different approaches of single-port robot-assisted radical prostatectomy (SP-RARP). A retrospective review was performed on patients who underwent SP-RARP between February 2019 and December 2022. Demographic and clinical information was collected from the multi-institutional, prospectively-maintained Single-Port Advanced Research Consortium (SPARC) database. Data were analyzed using IBM Statistical Packaging for Social Sciences (SPSS) version 29.0 with descriptive statistics as presented. A total of 1103 patients were identified, consisting of 244 (22.1%), 712 (64.6%), and 147 (13.3%) cases performed via transperitoneal, extraperitoneal (EP), and transvesical (TV) approaches, respectively. During a median follow-up time of 11 months (interquartile range 5.7-17.1 months), only two cases of incisional hernia were reported. Both cases occurred following transperitoneal SP-RARP with one patient requiring surgical repair. There remains no evidence of postoperative hernia following EP and TV SP-RARP at the completion of our review. SP-RARP was associated with low risk for postoperative hernia. The risk was lower following TV and EP SP-RARP where the peritoneum is preserved.

Modern approaches to the treatment of postoperative hernias

One of the most common surgical pathologies are external abdominal hernias. The share of postoperative ventral hernias (POVH) accounts for up to 15-18% of the total number of patients with abdominal hernias. More than 1.5 million surgical interventions for ventral hernias are performed annually in the world, in the CIS countries this figure exceeds 200,000 operations. Modern studies have shown that the surgical treatment of patients with POVH should be based on a personalized approach, taking into account the existing concomitant pathologies, risk factors, surgical potential of the operating go doctor and hospital.

Machine Learning Analysis of Postlaparoscopy Hernias and “I'm Leaving You to Close” Strategy

IntroductionContributing factors to postlaparoscopy hernia are unknown. We hypothesized that postlaparoscopy incisional hernias are increased when the index surgery was performed in teaching hospitals. Laparoscopic cholecystectomy was chosen as the archetype for open umbilical access. Materials and methodsMaryland and Florida SID/SASD databases (2016-2019) wereused to track 1-year hernia incidence in both inpatient and outpatient settings, which was then linked to Hospital Compare, Distressed Communities Index (DCI), and ACGME. Postoperative umbilical/incisional hernia following laparoscopic cholecystectomy was identified using CPT and ICD-10. Propensity matching and eight machine learning modes were utilized including logistic regression, neural network, gradient boosting machine, random forest, gradient boosted trees, classification and regression trees, k nearest neighbors and support vector machines. ResultsPostoperative hernia incidence was 0.2% (total = 286; 261 incisional and 25 umbilical) in 117,570 laparoscopic cholecystectomy cases. Days to presentation (mean ± SD) were incisional 141 ± 92 and umbilical 66 ± 74. Logistic regression performed best (AUC 0.75 (95% ci 0.67-0.82) and accuracy 0.68 (95% ci 0.60-0.75) using 10-fold cross validation) in propensity matched groups (1:1; n = 279). Postoperative malnutrition (OR 3.5), hospital DCI of comfortable, mid-tier, at risk or distressed (OR 2.2 to 3.5), LOS >1 d (OR 2.2), postop asthma (OR 2.1), hospital mortality below national average (OR 2.0) and emergency admission (OR 1.7) were associated with increased hernias. A decreased incidence was associated with patient location of small metropolitan areas with <1 million residents (OR 0.5) and Charlson Comorbidity Index-Severe (OR 0.5). Teaching hospitals were not associated with postoperative hernia after laparoscopic cholecystectomy. ConclusionsDifferent patient factors as well as underlying hospital factors are associated with postlaparoscopy hernias. Performance of laparoscopic cholecystectomy at teaching hospitals is not associated with increased postoperative hernias.

The utilization of an absorbable mesh after ostomy reversal does not decrease incisional hernia rates

BackgroundPostoperative ostomy reversal hernias are common and can create strain on the healthcare system.There is little literature evaluating the utilization of absorbable mesh following ostomy reversal. The effect on subsequent hernia rates at our institution has not been evaluated. We examine if the addition of absorbable mesh decreases the postoperative hernia rate in our patient population. MethodsWe performed a retrospective review of all ileostomy and colostomy reversals. Patients were divided into two groups based on whether an absorbable mesh was used at ostomy closure or not. ResultsHernia recurrence rates were lower in the group that had mesh reinforcement (8.96%) vs the group that did not receive a mesh (14.8%) though this was not statistically significant (p = 0.233). ConclusionProphylactic use of an absorbable biosynthetic mesh did not alter the rate of incisional hernia rates following ostomy reversal in our cohort of patients.
