ABSTRACT
IntroductionAbdominal wall hernias are a common surgical problem. Lakhs of patients are affected eachyear, most commonly presenting with primary ventral, incisional, and inguinal hernias.Whether symptomatic or asymptomatic, hernias commonly cause pain or aestheticallydistressing to patients. These concerns, coupled with the risk of incarceration, are the mostcommon reasons patients seek surgical repair of hernias. The presence of a ventral hernia isitself, an indication for repair. The tension-free repair has revolutionized hernia surgery. Theuse of mesh prosthesis to approximate the fascial defect has resulted in a decrease inrecurrence rates for any hernias.Material and methodsA clinical study of 60 cases of ventral hernia has been done during the period from march2019 to April 2021 on inpatient admitted to tertiary care teaching L.G. hospital, Ahmedabadwith follow up period of 6 months.Results• 60 cases of ventral hernias were studied with follow up a period of 6 months. Commonestventral hernia was umbilical hernia which accounts for 60% of cases. Swelling was the mostcommon complaint in 91.66% pts. Mesh repair is the technique of choice for all ventralhernias with large defect. Though retro rectus mesh placement is more physiological.Laparoscopic approach for ventral hernia repair has advantages of good operative fieldvisibility, lessened duration of hospital stays, minimal postoperative scar. Laparoscopic repairis gaining good acceptance in current era and time. Complications in both open approach andlaparoscopic approach remain same.ConclusionIrrespective of advance nourishment and decreased number of pregnancies as compared tothe past, still abdominal wall hernia is not infrequent. Simultaneously; multiple and effectivesurgical techniques and various planes of mesh placement, have increased cure rate up to100% with minimum serious post operative complication.
ABSTRACT
@#Morgagni hernia is a rare form (accounting for 2%) of congenital diaphragmatic hernia. The traditional treatment for Morgagni hernia includes thoracotomy and laparotomy. However, surgical trauma limits its adoption. We reported the results of 2 patients with congenital Morgagni hernias in adults and described the operation methods of the patients. The 2 patients recovered uneventfully. No evidence of recurrence was found after 5 years follow-up. Laparoscopic repair for Morgagni hernia with mesh is applicable for obese, aged and bilateral Morgagni hernias patients.
ABSTRACT
Background: Incisional hernia is a common complication after laparotomy. Up to now, there is no consensus on the ideal surgical approach of such hernia. The aim of the present study was to compare the surgical outcomes, feasibility and cost effectiveness of the open mesh repair and laparoscopic repair of incisional hernia.Methods: A randomized controlled study conducted between August 2015 and September 2019 in which 64 patients with incisional hernias were randomly selected for either open mesh repair (36 patients) or laparoscopic repair (28 patients).Results: Patients in both groups were similar in their characteristics. The mean operative time was significantly longer in laparoscopic repair than in open mesh repair (128.6±15 minutes versus 89.8±82 minutes, p<0.05). The peri-operative complications and intra-operative blood loss were comparable in the two groups. The use of the drain was significantly higher in open group than in laparoscopic repair group (44.4% versus 10.7%). The overall rate of postoperative complications was similar in both groups, (25% for each group). The rate of wound infection and the length of hospitalization were significantly less in laparoscopic repair group. The results of postoperative pain score, cosmetic outcomes and recurrence rate showed no significant differences between the two groups but patient's satisfaction was significantly higher in laparoscopic repair. p>0.05.Conclusion: Both laparoscopic and conventional open mesh repair of incisional hernia are equivalent and feasible and safe technique. Laparoscopic repair was superior to open mesh repair in term of surgical site infection, hospital stay and patient’s satisfaction only.
ABSTRACT
Background: Globally, inguinal hernia is the most common type of hernia, comprising of approximately 75% of all abdominal wall hernias.Aim of the study was to compare the heavyweight composite polypropylene mesh versus the prolene soft mesh for the reduction of post-operative pain in patients undergoing lichensteins mesh repair for inguinal hernia.Methods: This study was conducted in the Department of General Surgery, KLES Dr. Prabhakar Kore Hospital and Medical Research Centre, Belgaum attached to KLE University’s J.N.M.C Belgaum.Results: Male preponderance was seen with 96.67% of patients in group SP and all (100%) patients in group RP were males. The mean age in group SP was 51.93±18.73 years compared to 49.50±14.03 years in group RP (p=0.571). The mean duration of the disease was 12.67±9.85 months in group SP whereas in group RP it was 15.10±8.98 months (p=0.321). The mean pulse rate in group SP and RP (79.60±5.64 vs 82.37±5.46 /min; p=0.059), systolic blood pressure (120.33±9.99 vs 124.33±11.94 mmHg; p=0.165) and diastolic blood pressure (73.73±6.76 vs 75.80±8.59 mmHg; p=0.305) were comparable. Right position was noted in 56.67% of patients in group SP compared to 50% of patients in group RP (p=0.673).Conclusions: Prolene soft mesh (lightweight macro-porous polypropylene mesh) significantly reduced the post-operative pain in patients undergoing lichensteins mesh repair for inguinal hernia as compared to heavyweight composite polypropylene mesh.
ABSTRACT
Background: Chronic groin pain (inguinodynia) following inguinal hernia repair is a significant, though under-reported problem. Mild pain lasting for a few days is common following mesh inguinal hernia repair. However, moderate to severe pain persisting more than 3 months after inguinal herniorrhaphy should be considered as pathological. The main aim of this study was to assess the incidence of inguinodynia in inguinal hernia repair patients at a tertiary centre.Methods: This non-randomized retrospective study was undertaken in the department of general surgery, SMIMER Hospital, Surat, Gujarat, India from August 2016 to July 2019. Total 940 patients were operated for inguinal hernia repair during this period. Out of these 940 patients, only 460 patients could be traced for clinical evaluation as Surat is an industrial city with very high percentage of migrant population and so only, they were included in the study.Results: In this study, total 460 patients were included, in which 310 patients were operated for open inguinal hernia repair and 150 patients were operated for laparoscopic hernia repair. Total 102 (22.17%) patients has developed inguinodynia out of 460 patients evaluated in this series. Incidence of inguinodynia is more in open inguinal hernia repair than laparoscopic inguinal hernia repair i.e., 24.83% versus 16.67%. Incidence of testicular complication in inguinodynia patients is more in open inguinal hernia repair and non in laparoscopic repair.Conclusions: Authors conclude that overall incidence of inguinodynia is 22.17% and incidence of inguinodynia is higher in open hernia repair in comparison to laparoscopic hernia repair (24.83% versus 16.67%). The incidence of mild inguinodynia is approximately eight times more common than severe inguinodynia.
ABSTRACT
Background: Incisional hernia is a common complication of abdominal surgery. Historically the open repair with or without mesh was the mainstay of treatment. However, many recently published laparoscopic repair studies have challenged surgeons to re-evaluate which technique provides the best short and long term outcomes.Methods: The study was conducted on 50 patients admitted at GMC Bhopal with approval from college ethical committee.Results: In 50 cases 21 were male and 29 were female. 7 male (14%) and 15 female (30%) patients had undergone laproscopic mesh repair (LMR) and 14 male (28%) and 14 female (28%) patients had undergone open mesh repair (OMR). Total complication in OMR group is 10 (35%) and in LMR group is 2 (9.09%). Mean duration of hospital stay in LMR group was 6.6 days and in OMR group was 15.57 days. Post-operative patients of LMR group returned back to the work early (mean 12 days) compared to OMR group (mean 20.7 days). Mean post-operative day of movement in LMR group was 1 day and in OMR group was 2.03 days. Pain measured using visual analogue score on 3rd post-operative day showed decreased pain score in laparoscopic group (mean 2) compared to open group (mean 5.35).Conclusions: Laparoscopic incisional hernia repair provides lesser post-operative pain, lesser complications, shorter hospital stay and lesser economic impact as they returned to work early. Thus patients have less morbidity and improved quality of life.
ABSTRACT
Amyand’s hernia is a rare pathology of an appendix with or without inflammation within the hernia sac is named after the French born English surgeon Dr. Claudius Amyand. We hereby present a case report of this rare entity known as a type 2 Amyand’s hernia. A 64 years old male, who had had a left-sided inguinal hernia for the previous 5 years, presented with a 2-day-history of fever, pain, vomiting, and irreducibility of the hernia. Upon exploration an irreducible inguinal hernia with appendix as its content was identified. Appendectomy was performed followed by a tension free mesh repair of the underlying hernia. Consequently, our recommendation is that the decision to perform an appendectomy and/or to use mesh to repair hernias should always be individualized.
ABSTRACT
Ventral hernia is a fascial defect located on the abdominal wall. Primary ventral hernias are named as umbilical, epigastric, spigelian and lumbar hernias. A lumbar hernia is a parietal wall defect that may occur anywhere in the lumbar region between the 12th rib and the iliac crest. A 47-year-old female, came with complaints of mass in left lower abdomen since 2 months. On clinical examination a defect of 8 × 8 cm was felt in the left lumbar region with positive cough impulse. CECT abdomen and pelvis was done to confirm lumbar hernia. Patient underwent mesh repair for the same. Lumbar and flank hernias are uncommon and are a challenge to treat for any general surgeon. Surgery is considered gold standard either an open mesh repair or laparoscopically.
ABSTRACT
Incisional hernia is one of the common complications encountered following abdominal surgery and is an important cause of morbidity. It can be repaired by following anatomical, mesh or laparoscopic methods. The incidence of these hernias is high even with recent advances in surgery, anaesthesiology, antibiotics, and suture materials used. We wanted to study the epidemiology, aetiology, mode of presentations, modalities of treatment and its outcome, of incisional hernia.METHODSThis study was done from July 2017 and June 2019, 50 patients with incisional hernia who got admitted in the Department of Surgery at Sri Venkateshwaraa Medical College and Research Center, Ariyur were subjected to anatomical or mesh repair depending on the surgeon’s choice and size of defect. A total of 50 cases were studied and followed for a period of 6- to 18-months. Patients of age 12 years and above of both sexes who presented with incisional hernia post abdominal surgery were included in this study. Age below 12 years and those presented with other hernias like inguinal/ventral hernias were excluded. Data was collected and analysed by various statistical methods. RESULTSIncisional hernia was found to be the second most common type of hernia. The incidence was more common in females, who underwent gynaecological procedures by lower midline incisions. It was found to be more common in the age group 30-60 years. Predominant risk factors being wound infection and obesity. Infraumbilical midline incision (50%) was found to be more common compared to other incisions. Majority of patients who underwent emergency surgery developed incisional hernia. Postoperative complications noted were mainly due to wound infections and seroma.CONCLUSIONSMesh repair results in less recurrence than anatomical repair for incisional hernia. The incidence of incisional hernia is more common in women than men due to abdominal wall weakness secondary to multiple pregnancies, increased number of caesarean sections and gynaecological surgeries. Sterile aseptic technique and appropriate use of pre-operative antibiotics is necessary to reduce the occurrence of incisional hernia.
ABSTRACT
Introduction: The intention of axillary lymph node dissection (ALND) is to stage the axilla precisely for prognostic information.This study is to assess the possibility of skip lesion in Level 3 in the absence of disease in Level 1 and 2 which may help inundertaking randomized controlled study to avoid Level 3 nodal dissection in our patients.Materials and Methods: Retrospective analysis of 60 patients who underwent surgery for invasive breast cancer from October2013 to October 2019 in the Department of Surgical Oncology, Government Thoothukudi Medical College Hospital, Thoothukudi,was performed.Results: About 33.3% of patients (20) were disease free in the axilla and the remaining 66.7% (40) had nodal involvement. Ofthose 39 patients who had nodal involvement in Level 1 and 2, 15 were found to have the disease in 4 or more nodes, 24 hadthe disease in <4 nodes. Totally 16 patients had metastases in Level 3 nodes. There is a 60% chance of involvement of Level3 when there is 4 or more nodal positivity in Level 1 and 2 and it drops to 25% if the involved nodal count becomes <4. Onepatient had skip lesion in Level 3 (4.8%) without disease in Level 1 and 2.Conclusion: Since there has been a dearth of randomized studies about levels of nodes to be addressed in ALND and studiesabout skip lesion in Level 3 from our country, we urge the need for more studies probably multicentric, regarding the extent ofALND. Until then, it may be fruitful to do complete ALND up to Level 3 for the better staging of the axilla.
ABSTRACT
Background: Umbilical hernia is one of the most commonly encountered hernia in surgical practice. A variety of repairs have been tried our ranging from open to laparoscopic. However controversy still persists as to which type of repair is the gold standard for umbilical hernia. Open technique comprises of the onlay mesh repair which is known to develop a variety of complications. Even laparoscopic approach also has failure rates as well as local complications. The aim of the study was to evaluate the surgical outcome of open retro rectus mesh repair for adult umbilical hernias.Methods: 50 consecutive cases of umbilical hernia were repaired by open technique with retro rectus placement of mesh.Results: There were no local complications or any recurrence in any of the fifty patients.Conclusions: Retro rectus placement of mesh in open repair of umbilical hernia in adults is a safe and effective modality of treatment.
ABSTRACT
Introduction: Incisional hernia is the most frequent post-operative complication following abdominal surgery. Several studies have shown that incisional hernias have different etiologies that are related to the patient, the surgical technique, the suture material, and the experience of the surgeon. Aim: This study aims to study various factors leading to the development of this condition and surgical techniques practiced to repair the incisional hernia. Materials and Methods: This retrospective study was conducted in the Department of General Surgery at Government Headquarters Hospital, Ramanathapuram, inpatient underwent surgery for incisional hernia. Data on clinical examination, type of operative procedure, and post-operative complications were collected. Results: Eighteen cases underwent surgery for an incisional hernia, female predominance, and age group of 31-40 years were common, the common previous surgery was laparotomy (56%), the common surgical incision is median vertical (50%). About 28% of patients had post-operative pain, 22% of patients had seroma, and 17% of patients had wound infection, no mesh-related infection noted in our study. Conclusion: In incisional hernias, the choice of operative technique is crucial. Incisional hernias occur more often in females as they are more likely to undergo lower abdominal surgeries. Mesh repair is considered superior to anatomical repair alone and we recommend laparoscopic hernioplasty as the first line of treatment.
ABSTRACT
Incisional hernia Complicates only 2%-10%. Spontaneous evisceration of content is very rare but whenever it occurs, it demands emergency surgery, to prevent further obstruction, strangulation of bowel and to cover its contents. The hernial contents can be covered primarily by mesh repair if the general condition of the patient and local condition of the operative site allows or can be covered by skin followed by delayed mesh repair. Authors report such rare case of spontaneous evisceration of omentum in 35 years old female patient who was known case of incisional hernia for 2 years. Neglect for early operative intervention or delay in seeking the treatment for an incisional hernia increases the risk of rupture.
ABSTRACT
Background: Hernia is generally defined as the protrusion of aviscus from the cavity in which it is normally contained or moreprecisely, as the protrusion of a loop or knuckle of an organ ortissue through an abnormal opening. Hence; the present studywas undertaken for assessing results of sutureless mesh repairof inguinal hernia.Materials & Methods: A total of 20 patients with inguinalhernia were enrolled in the present study. Patients who fulfilledthe inclusion criteria were included into the study after takingdetailed consent for the procedure. Inguinal hernia repair wasperformed by placing mesh on posterior inguinal wall andwithout applying fixation suture or glue. Postoperative follow-upwas done and Visual analogue scale (VAS) was used forassessment of postoperative pain on follow-up. All the resultswere recorded in Microsoft excel sheet and were analyzed bySPSS software.Results: Majority of the patients i.e. 45 percent of the patientsbelonged to the age group of 41 to 50 years, followed by 35percent of the patients who belonged to the age group of 20 to30 years. Punched out/diverticular defect in transversalis fasciawas present in 10 percent of the cases while normal posteriorwall was present in 90 percent of the cases. Mean duration ofoperative procedure was 41.25 minutes. Mean postoperativepain score at 12 hour and 24 hours was 2.95 and 1.84respectively.Conclusion: Sutureless tension free mesh repair in thetreatment of inguinal hernia cases is an effective technique.However; further studies are recommended.
ABSTRACT
The World Health Organization defines youth as 14 to 25 years old, and the inguinal hernia patients in this age group are still in the development stage of the body with special physiological characteristics and special needs for the protection of reproductive functions. Therefore, the repair method should be carefully selected for the special group and the principle of individualized treatment should be adhered to.The synthetic mesh has problems such as failure to extend with body growth, excessive scar hyperplasia compressing the spermaduct, and long-term invasion. The biological patch also has the risk of long-term recurrence or local bulging. For youth, standard tissue repair surgery can mending the defect well, with reasonable perioperative management, also can minimize the discomfort, which caused by excessive early postoperative tension. At the same time, tissue repair can adapt to the growth of the body, with relatively small impact on reproductive function, or can be combined with biological materials to repair large defects if necessary. After mastering tissue repair technology, the recurrence rate of tissue repair is acceptable. Therefore, tissue repair is of irreplaceable value in the treatment of young inguinal hernia patients.
ABSTRACT
Children's pelvic and abdominal wall muscles have not yet matured. The inguinal canal is shorter(can be less than 1 cm), and the ratio of thickness of abdominal wall to length of inguinal canal is almost 1:1. The distance between the internal ring and the external ring is so close that only requires a high level of ligation at internal ring, lacking of repairing basis. As the growth and development of pelvis, the length of the inguinal canal will also increase. Generally, when the length is more than 3 cm, there is the basic conditions of inguinal hernia repair, therefor under the age of 14 with groin hernia, the patient only need to receive a high ligation of the sac to restore the length and slope of the inguinal canal.Laparoscopic surgery is also in accordance with the basic principle. Mesh repair in primary inguinal hernia in childhood is suspected of overtreatment, at least is academical controversal.
ABSTRACT
Objective To investigate the clinical efficacy of laparoscopic-assisted linea alba reconstruction for postpartum diastasis recti.Methods The retrospective cross-sectional study was conducted.The clinical data of 14 patients with postpartum diastasis recti who were admitted to Ruijin Hospital of Shanghai Jiaotong University School of Medicine between June 2016 and June 2018 were collected.Patients underwent laparoscopic-assisted linea alba reconstruction.Observation indicators:(1) intra-and post-operative recovery situations;(2) follow-up.Follow-up using outpatient examination and telephone interview was performed to detect postoperative long-term complications,diastasis recti and umbilical hernia recurrence up to September 2018.Measurement data with normal distribution were represented as (x)±s and measurement data with skewed distribution were described as M (P25,P75).Results (1) Intra-and post-operative situations:14 patients underwent successful laparoscopic-assisted linea alba reconstruction and 8 complicated with umbilical hernia area of (6± 3) cm2 were sutured and closed.The mesh area,operation time,visual analogue score for pain at the first day after operation,time of postoperative drainage-tube removal and duration of postoperative hospital stay were respectively (214±26) cm2,(74 ± 14) minutes,3.7 ± 0.6,(3.3 ± 0.7) days and (4.1 ± 1.2) days.No patient required administration of analgesics and had postoperative complication.(2) Follow-up:14 patients were followed up for 17 months (5 months,21 months).During the follow-up,1 patient returned visit at postoperative day 10 due to surgical incision drainage and cured after dressing change.The other patients had no complications,without diastasis recti and umbilical hernia recurrence.Conclusion Laparoscopic-assisted linea alba reconstruction for postpartum diastasis recti is safe and effective.
ABSTRACT
Objective To investigate the clinical efficacy of mesh repair via inguinal approach in acute femoral hernia.Methods The retrospective cohort study was conducted.The clinical data of 48 patients with acute femoral hernia who were admitted to Huadong Hospital Affiliated to Fudan University between January 2007 and December 2016 were collected.Of 48 patients,29 undergoing hernia repair with polypropylene mesh and 19 undergoing hernia repair with suture were allocated into the study group and control group respectively.All the patients underwent hernia repair via inguinal approach.Observation indicators:(1) surgical and postoperative situations;(2) follow-up and survival situations.Follow-up was performed by outpatient examination and telephone interview to detect complications,hernia recurrence,survival situations at 1-,3-month and 1 year postoperatively for 1 year up to December 2017.Measurement data with normal distribution were represent as x±s and comparison between groups was done by the t test.Comparison of count data was analyzed using the chi-square test or Fisher exact probability.Results (1) Surgical and postoperative situations:patients in the 2 groups underwent successful incarcerated or strangulated acute femoral hernia repair.There were 3 and 4 patients receiving small bowel resection in the study group and control group respectively,with no statistically significant difference between groups (x2=1.50,P＞0.05).The operation time was respectively (82±16)minutes and (96± 13)minutes in the study group and control group,with statistically significant difference between groups (t =-2.94,P＜0.05).There was no femoral vascular injury in the 2 groups.The time of drainage-tube removal and duration of postoperative hospital stay were respectively (4.5 ± 1.6) days and (9±4) days in the study group and (3.9± 1.3)days and (10±4)days in the control group,with no statistically significant difference between groups (t =1.36,-0.33,P＞0.05).(2) Follow-up and survival situations:all the 48 patients were followed up for one year.No mesh infection was found in the study group.[ncisional infection was detected in 4 and 2 patients of the study group and control group respectively,with no statistically significant difference between groups (x2 =0.11,P＞ 0.05).Patients with incisional infection were cured after incision open drainage.Two and 2 patients had postoperative chronic pain in the study group and control group respectively,with no statistically significant difference between groups (x2 =0o 20,P＞0.05).The 4 patients had mild intermittent pain,without special treatment.There were no seroma occurred in the 2 groups.Hernia recurrence was occurred in 0 aud 5 patients of the study group and control group respectively,with statistically significant difference between groups (x2 =8.52,P＜0.05).There were 2 and 1 patient dead in the study group and control group respectively,with no statistically significant difference between groups (P ＞ 0.05).Conclusions Hernia repair with Polypropylene mesh via inguinal approach in acute femoral hernia is safe and feasible.Compared to suture repair,it can not only shorten operation time and reduce hernia recurrence,but also had no mesh infection and cannot iucrease postoperative complications.
ABSTRACT
Objective To investigate the incidence and influence factors of chronic postoperative inguinal pain (CPIP) after tension-free repair for inguinal hernia.Methods The retrospective case-control study was conducted.The clinicopathological data of 1 188 patients who underwent tension-free repair for inguinal hernia in the People's Hospital of Xinjiang Uygur Autonomous Region between January 2011 and August 2017 were collected.Observation indicators:(1) surgical and postoperative situations;(2) follow-up;(3) influence factors analysis of CPIP.Follow-up using outpatient examination and telephone interview was performed to detect inguinal pain and complications at 1,3,6 months and 1 year postoperatively up to August 2018.Measurement data with normal distribution were represented as x ±s.Measurement data with skewed distrubution were described as M (range).The univariate and multivariate analysis were done using the chi-square test and Logistic regression model.Results (1) Surgical and postoperative situations:1 188 patients underwent successful tension-free repair for inguinal hernia.Eighty-five patients (7.155％,85/1 188) had CPIP,including 76 (8.370％,76/908) undergoing open surgery and 9 (3.214％,9/280) undergoing laparoscopic surgery.(2) Follow-up:1 188 patients were followed up for 12-36 months,with a median time of 19 months.Incidence rates of CPIP with visual analogue score ＞ 3were 11.785％(140/1 188),7.155％(85/1 188),5.808％(69/1 188),3.199％(38/1 188) at 1,3,6 months and 1 year postoperatively.Patients were given individualized and reasonable treatment according to their own conditions and CPIP was relieved after conservative treatment including drug treatment,physiotherapy such as acupuncture,nerve block and psychotherapy.Of 5 patients with CPIP after tension-free repair for inguinal hernia undergoing surgeries,1 was relieved nerve ligation by surgery,3 with mesh related pain were removed meshes,1 was taken the fixed stiches out.They were relieved CPIP after above treatments.During the follow-up,161 patients with incisional seroma,75 with incisional infection and 5 with disruption of wound were cured by symptomatic treatments including reinforced incision management,dressing change and physiotherapy.Seven patients with mesh infection were removed meshes.Of 68 patients with hernia recurrence,53 had reoperation,18 complicated with diseases induced severe increased intra-abdominal pressure were suggested to undergo surgeries after treatment of complications.(3) Influence factors analysis of CPIP:① results of univariate analysis showed that sex,age,bodymass index,surgical method,degree of preoperative pain,intraoperative nerve stretching or injury and incisional infection were related factors affecting CPIP after tension-free repair for inguinal hernia (x2 =21.002,6.715,6.012,8.563,11.887,49.447,10.025,P＜0.05).② Results of multivariate analysis showed that sex,body mass index,surgical method,degree of preoperative pain,intraoperative nerve stretching or injury and incisional infection were independent related factors affecting CPIP after tension-free repair for inguinal hernia (odds ratio =1.267,2.986,1.661,3.208,2.034,1.871,95％ confidence interval:1.042-1.392,1.372-4.901,0.998-2.758,1.933-6.013,1.556-3.118,1.095-3.534,P＜0.05).Conclusions Sex,body mass index,surgical method,degree of preoperative pain,intraoperative nerve stretching or injury and incisional infection are independent related factors affecting CPIP after tension-free repair for inguinal hernia.Preoperative pain management and psychological counseling,intraoperative refine performance,inguinal nerve protection and postoperative incisional management should be reinforced to prevent and reduce incidence of CPIP.
ABSTRACT
Objective To investigate the application value of DynaMesh-IPST stoma dedicated mesh in parastomal hernia repair.Methods The retrospective cohort study was conducted.The clinical data of 281 patients with parastomal hernia of abdominal wall who were admitted to Beijing Chao-Yang Hospital of Capital Medical University between March 2013 and April 2017 were collected.Of 281 patients undergoing laparoscopic combined with open parastomal hernia repair with artificial materials,151 using DynaMesh-IPST stoma dedicated mesh and 130 using ordinary anti-adhesive mesh were respectively allocated into the DynaMesh-lPST mesh group and ordinary mesh group.Observation indicators:(1) intra-and post-operative situations;(2) follow-up.Follow-up using outpatient examination and telephone interview was performed to detect hernia recurrence and long-term complications at 1-,3-,6-month and 1 year postoperatively up to June 2018.Measurement data with normal distribution were represented as (x)±s and comparison between groups was done by the t test.Measurement data with skewed distribution were described as M (P25,P75) and M (range),and comparison between groups was done using rank sum test.Comparison of count data between groups was analyzed using the chi-square test.Results (1) Intra-and post-operative situations:281 patients underwent successfully laparoscopic combined with open parastomal hernia repair with artificial materials.The operation time,volume of intraoperative blood loss and duration of postoperative hospital stay were 100 minutes (60 minutes,120 minutes),(34± 15)mL,17 days (13 days,24 days) in the DynaMesh-IPST mesh group and 100 minutes (85 minutes,120 minutes),(42± 36)mL and 20 days (16 days,25 days) in the ordinary mesh group,with statistically significant differences between groups (Z=2.166,t=2.654,Z=2.795,P＜0.05).The postoperative incisional infection and intestinal leakage were respectively detected in 18 and 2 patients in the DynaMesh-IPST mesh group and 36 and 7 patients in the ordinary mesh group,showing a statistically significant difference of incisional infection between groups (x2 =11.194,P＜0.05),and no statistically significant difference of intestinal leakage between groups (x2 =4.234,P＞ 0.05).Of 54 patients with postoperative incisional infection,4 were cured after removing mesh and clearing up infection,50 were cured after dressing change,local debridement and drainage.(2) Follow-up:279 of 281 patients including 149 in the DynaMesh-IPST mesh group and 130 in the ordinary mesh group were followed up for 20-44 months with a median time of 32 months.During the follow-up,10 patients had hernia recurrence including 4 in the DynaMesh-IPST mesh group and 6 in the ordinary mesh group.Six of them underwent reoperation (4 with keyhole hernia recurrence,1 with mesh bulging out because of abdominal weakness at stoma,1 with parastomal recurrence after mesh removal due to intestinal leakage) and 4 had regular reexamination after fixation with abdominal belt.There was no statistically significant difference of hernia recurrence between groups (x2 =0.318,P＞0.05).Twenty-seven patients (14 in the DynaMesh-IPST mesh group and 13 in the ordinary mesh group) with intestinal obstruction were improved by conservative treatment,showing no statistically significant difference between groups (x2 =0.043,P＞0.05).Ten patients (6 in the DynaMesh-IPST mesh group and 4 in the ordinary mesh group) with stoma stenosis were improved after local stoma remodeling,showing no statistically significant difference between groups (x2=0.007,P＞ 0.05).Ninteen patients (4 in the DynaMesh-IPST mesh group including 1 complicated with hernia recurrence and 15 in the ordinary mesh group including 2 complicated with hernia recurrence) with stoma prolapse were improved after local stoma remodeling,showing a statistically significant difference between groups (x2 =8.756,P ＜ 0.05).Conclusion Parastomal hernia repair with DynaMesh-IPST stoma dedicated mesh is safe and feasible,with satisfactory effects.
