Clinical observation of extraction-site incisional hernia after laparoscopic colorectal surgery

BACKGROUND Laparoscopic colorectal cancer surgery increases the risk of incisional hernia(IH)at the tumor extraction site.AIM To investigate the incidence of IH at extraction sites following laparoscopic colo-rectal cancer surgery and identify the risk factors for IH incidence.METHODS This study retrospectively analyzed the data of 1614 patients who underwent la-paroscopic radical colorectal cancer surgery with tumor extraction through the abdominal wall at our center between January 2017 and December 2022.Diffe-rences in the incidence of postoperative IH at different extraction sites and the risk factors for IH incidence were investigated.RESULTS Among the 1614 patients who underwent laparoscopic radical colorectal cancer surgery,303(18.8%),923(57.2%),171(10.6%),and 217(13.4%)tumors were ex-tracted through supraumbilical midline,infraumbilical midline,umbilical,and off-midline incisions.Of these,52 patients developed IH in the abdominal wall,with an incidence of 3.2%.The incidence of postoperative IH was significantly higher in the off-midline incision group(8.8%)than in the middle incision groups[the supraumbilical midline(2.6%),infraumbilical midline(2.2%),and umbilical incision(2.9%)groups](χ^(2)=24.985;P<0.05).Univariate analysis showed that IH occurrence was associated with age,obesity,sex,chronic cough,incision infection,and combined diabetes,anemia,and hypopro-teinemia(P<0.05).Similarly,multivariate analysis showed that off-midline incision,age,sex(female),obesity,incision infection,combined chronic cough,and hypoproteinemia were independent risk factors for IH at the site of laparoscopic colorectal cancer surgery(P<0.05).CONCLUSION The incidence of postoperative IH differs between extraction sites for laparoscopic colorectal cancer surgery.The infraumbilical midline incision is associated with a lower hernia rate and is thus a suitable tumor extraction site.

Occurrence and prevention of incisional hernia following laparoscopic colorectal surgery

Among minimally invasive surgical procedures,colorectal surgery is associated with a notably higher incidence of incisional hernia(IH),ranging from 1.7% to 24.3%.This complication poses a significant burden on the healthcare system annually,necessitating urgent attention from surgeons.In a study published in the World Journal of Gastrointestinal Surgery,Fan et al compared the incidence of IH among 1614 patients who underwent laparoscopic colorectal surgery with different extraction site locations and evaluated the risk factors associated with its occurrence.This editorial analyzes the current risk factors for IH after laparoscopic colorectal surgery,emphasizing the impact of obesity,surgical site infection,and the choice of incision location on its development.Furthermore,we summarize the currently available preventive measures for IH.Given the low surgical repair rate and high recurrence rate associated with IH,prevention deserves greater research and attention compared to treatment.

Clinical and Therapeutic Aspects of Inguinal Hernia in Children in the General Surgery Department of Reference Health Center in Commune I of Bamako Mali

Inguinal hernia in children is a congenital pathology in children linked to the persistence of the peritoneo-vaginal canal in children and the NüCK canal in girls;persisting into adulthood. This work aimed to study inguinal hernia in children in the general surgery department of the Reference Health Center of Commune I of the Bamako District;to determine the frequency of inguinal hernia;describe the epidemiological, clinical and therapeutic aspects of inguinal hernias and in order to evaluate the cost of treatment. This was a prospective study from April 2017 to March 2018 during which 60 children with an inguinal hernia were collected. Inguinal hernias in children represented 9.23% of patients operated on in the department. The average age was 59.23 months with extremes of one month and 180 months and a standard deviation of 49.23 years. The male sex was dominant with a sex ratio equal to 9:1. The notion of prematurity was found in 11.7% and was associated with a testicle not in place in 1.7% of cases. 41.7% of our patients were referred by a doctor and 66.7% of patients presented with painless, intermittent inguino-scrotal swelling (83.3% of cases). The hernia was discovered before one week of life in 50% of cases. Inguinal swelling was absent in 11.7% but observed intraoperatively. The inguinal hernia was unilateral in 91.7% of cases and 70% of hernias were discovered by the parents during pushing efforts. The inguinal hernia was located on the right in 61.7% of cases. The hernia swelling was soft, painless, impulsive and reducible in 78.3% of cases. The swelling was inguino-scrotal in 58.3% of cases. The hernia was simple in 95% of patients and hernial strangulation was observed in 3 cases or 5% of cases. 98.3% of patients were ASA I. The treatment was carried out openly in all our patients including closure of the vaginal peritoneal canal in 95% of cases under general anesthesia in 98.3% of cases. The morbidity rate was 8.4% (surgical site infection: 6.7% of cases and hematoma: 1.7%). The immediate consequences were simple in 96.6% of cases. No cases of recurrence occurred during the 6 months after the intervention. The average cost of care was estimated at 69,743 FCFA.

Laparoscopic Surgery of Incisional Hernia: Technique and Short-Term Results in Three Surgical Units in Cameroon

Introduction: Incisional hernia is a common medical situation and its treatment has always been a challenge for general surgeons. If laparoscopic repair has become a gold standard elsewhere, it is increasingly done in our milieu, but no data has been found. The aim of this study was to review this surgery done in our country so far, to describe the operative technique and to evaluate the postoperative outcomes. Patients and Methods: We conducted an observational descriptive study with retrospective collection of data from the 1st of July 2018 to 30th of June 2022, in three hospitals in Cameroon. Data on socio-demographic and clinical characteristics, surgical technique and postoperative outcomes of patients who had a laparoscopic repair of their incisional hernia were collected. Results: We reviewed 20 files. There were 14 women with an average age of 54.6 years. The average BMI was 32.8 kg/m2. Thirteen patients had a moderate size hernia and the hernia was localized at the midline in 18 cases. Only composite biface meshes were used with dimensions chosen to obtain at least 5 cm overlap. Spiral tacks were the only fixation means used. We registered 3 complications. One case of generalized peritonitis secondary to missed digestive perforation, one case of seroma and one case of postoperative ileus. We registered no death. Conclusion: Laparoscopic repair of incisional hernias is feasible in a resource-limited setting like ours. Compliance with the operative technique and recommendations is important to obtain short-term results closed to that put forward by literature.

Evaluating the Impact of Transcutaneous Electrical Nerve Stimulation on Patients Undergoing Inguinal Hernia Surgery: A Meta- Analysis of Randomized Controlled Trials

Objective:A comprehensive meta-analysis based on the latest randomized controlled trials(RCTs)was conducted to investigate the effects of transcutaneous electrical nerve stimulation(TENS)on patients undergoing treatment after inguinal hernia surgery.Methods:A detailed search of Embase,PubMed,Web of Science,and the Cochrane Library was performed for RCTs investigating the use of TENS during inguinal hernia surgery up to September 28,2021.The Cochrane tool was applied to assess the risk of bias in the included studies.Results:Seven eligible RCTs with a total of 379 cases were included.The meta-analysis showed a mean difference(MD)in VAS of-1.61[95%CI:-2.20-1.02,P<0.00001]at 2 hours post-operation,VAS MD=-1.33 at 4 hours post-operation[95%CI:-2.84-0.18,P=0.09],VAS MD=-2.36 at 8 hours post-operation[95%CI:-4.04-0.69,P=0.006],and VAS MD=-1.75 at 24 hours post-operation[95%CI:-2.64-0.85,P=0.0001].The cortisol level MD at 24 hours post-operation was-52.56[95%CI:-168.8-63.76,P=0.38].Conclusion:TENS significantly reduces postoperative pain following inguinal hernia surgery and promotes patient recovery.TENS is recommended for patients undergoing inguinal hernia surgery.However,further high-quality studies are needed to confirm additional effects.

Urogenital Complications of Groin Hernia Surgery: A Multicentre Study in Guinea

Context and Objective: Groin hernia is a common pathology in visceral surgery (2nd rank after appendicitis), which affects approximately 4.6% of the African population. Restoring the normal anatomy of the groin region is one of the most benign interventions. However, uro-andrological complications are possible. This study aimed to contribute to the improvement of the management of urogenital complications of groin hernia surgery. Patients and Method: We carried out a prospective study of descriptive type with a duration of 6 months from 1 August 2021 to 31 January 2022. The data were collected using a pre-established survey sheet. The study covered several sites (public hospitals and private clinics) in Guinea. Results: The urogenital complications of the surgery of the hernia of the groin represented 15.22% or 14 cases out of 92 patients. The average age was 37.00 years with extremes of 20-69 years. Polygamists occupied the first place. The reason for consultation was dominated by decreased testicular volume (42.86%), followed by a desire to conceive (21.43%). Unilateral testicular atrophy represented 63.64%, bilateral 27.27%. We performed a left orchidectomy in one patient and a cystorraphy in another simple operative follow-up. The other cases consisting of testicular atrophy, due to lack of a suitable technical platform, did not benefit from any specific therapeutic treatment. Conclusion: Urogenital complications of groin hernia surgery are relatively common. Testicular atrophy was the main clinical complication. The left orchidectomy and cystorraphy were the therapeutic procedures performed.

Analysis of the Effect and Efficiency of Tension- Free Hernia Repair and Traditional Surgery in The Treatment of Hernia

Objective: To analyze the efficiency of tension-free hernia repair and traditional surgery in the treatment of hernia. Methods: A total of 80 patients with hernias were selected and randomly into a control group (traditional hernia repair) and an observation group (tension-free hernia repair), of 40 cases each. The perioperative indicators, pain, physiological stress indicators, complications, and recurrence rates between the two groups were compared. Results: The perioperative indexes of the observation group were better than those of the control group (P < 0.05). The postoperative pain score, postoperative physiological stress index level, incidence of complications, and recurrence rate of the observation group were lower than those of the control group (P < 0.05). Conclusion: In the surgical treatment of hernia, tension-free hernia repair was less traumatic and had a better effect than traditional hernia repair.

Internal hernia as a rare cause of small bowel obstruction:An insight from 13 years of experience

BACKGROUND Internal hernia(IH)is a rare culprit of small bowel obstruction(SBO)with an incidence of<1%.It poses a considerable diagnostic challenge requiring a high index of suspicion to prevent misdiagnosis,improper treatment,and subsequent morbidity and mortality.AIM To determine the clinico-demographic profile,radiological and operative findings,and postoperative course of patients with IH and its association with SBO.METHODS Medical records of 586 patients with features of SBO presenting at a tertiary care centre at Lucknow,India between September 2010 and August 2023 were reviewed.RESULTS Out of 586 patients,7(1.2%)were diagnosed with IH.Among these,4 had congenital IH and 3 had acquired IH.The male-to-female ratio was 4:3.The median age at presentation was 32 years.Contrast-enhanced computed tomography(CECT)was the most reliable investigation for preoperative identification,demonstrating mesenteric whirling and clumped-up bowel loops.Left paraduodenal hernia and transmesenteric hernia occurred with an equal frequency(approximately 43%each).Intraoperatively,one patient was found to have bowel ischemia and one had associated malrotation of gut.During follow-up,no recurrences were reported.CONCLUSION IH,being a rare cause,must be considered as a differential diagnosis for SBO,especially in young patients in their 30s or with unexplained abdominal pain or discomfort post-surgery.A rapid imaging evaluation,preferably with CECT,is necessary to aid in an early diagnosis and prompt intervention,thereby reducing financial burden related to unnecessary investigations and preventing the morbidity and mortality associated with closed-loop obstruction and strangulation of the bowel.

Fatal risk in hysteroscopic surgery that should not be overlooked:Uterine artery pseudoaneurysm

This article provides a detailed account of the diagnosis and treatment of a case involving a uterine artery pseudoaneurysm(UAP),as well as an analysis of UAP etiology.This finding emphasizes that UAP should be considered in patients presenting with abnormal genital bleeding after hysteroscopy and offers valuable insights and lessons for gynecologists in hysteroscopic procedures.The patient underwent timely relevant examinations to confirm the diagnosis,allowing for crucial time required for her treatment.In this study,the primary cause of UAP formation in the patient was attributed to a prior hysteroscopic surgical procedure conducted at another medical facility,suggesting that the selection and imple-mentation of dilatation catheters are some of the predisposing factors for UAP.In conclusion,this case study offers a comprehensive analysis of the etiology of UAP and effectively provides timely diagnosis and treatment,offering valuable in-sights for the clinical diagnosis and management of UAP.

Cauda equina syndrome with urinary retention as a postoperative complication of lumbar spine surgery:A case report

BACKGROUND Cauda equina syndrome(CES)is characterized by a group of symptoms that may be caused by inflammation,spinal cord compression,venous congestion,or ischemia.This syndrome is commonly an indication for surgical intervention but has not been determined as a postoperative complication following surgery for lumbar spine disease.CASE SUMMARY To report the case of a 54-year-old male patient who had CES following spinal surgery,with no obvious compression lesions found during re-exploration,suggesting that vascular insufficiency may have contributed to the condition.Furthermore,a series of urodynamic studies on bladder recovery patterns in such complications have also been investigated.CONCLUSION Postoperative CES requires urgent imaging and exploration to rule out compression;noncompressive cases,including vascular insufficiency may performed conservative management.

Root canal therapy combined with endoscopic sinus surgery for odontogenic sinusitis:Efficacy comparison in a cohort study

BACKGROUND Odontogenic maxillary sinusitis,often triggered by dental issues like periapical periodontitis,significantly contributes to chronic sinusitis,mainly affecting adults around 50 years old,emphasizing the need for a multidisciplinary diagnostic and treatment approach.AIM To investigate the therapeutic effect and clinical value of root canal therapy combined with nasal endoscopic surgery compared with simple root canal the-rapy in the treatment of severe odontogenic maxillary sinusitis caused by peria-pical periodontitis.METHODS The clinical data,diagnosis,and treatment of 200 patients with severe odonto-genic maxillary sinusitis caused by periapical periodontitis from October 2020 to October 2021 were analyzed retrospectively.Among them,63 patients were treated with simple root canal therapy as the control group,and 137 patients were treated with root canal therapy combined with nasal endoscopic surgery as the observation group.The therapeutic effect,Lund-Kennedy endoscopic score,paranasal sinus Lund-Mackay score,complication rate,recurrence rate,and patient satisfaction were compared between the two groups.RESULTS First,we compared the effective rates:23 cases were cured,22 were improved,and 8 were ineffective in the control group,yielding a total effective rate of 84.90%.Meanwhile,97 cases were cured,34 improved,and 6 were ineffective in the observation group,resulting in a total effective rate of 95.62%.The observation group had a higher total effective rate compared with the control group(P<0.05).Second,we compared the Lund–Kennedy endoscopic score.Before treatment,no significant difference(P>0.05)was observed in this score between the two groups.After treatment,the Lund–Kennedy endoscopic score decreased in both groups.The Lund–Kennedy endoscopic score of the observation group at 3 and 6 mo after treatment was lower compared to that of the control group(P<0.05).Third,we compared the Lund–Mackay score of paranasal sinuses.Before treatment,there was no significant difference in this score between the two groups(P>0.05).After treatment,the Lund–Mackay scores of paranasal sinuses decreased in both groups.The Lund–Mackay scores of paranasal sinuses in the observation group at 3 and 6 mo after treatment were lower compared to those of the control group(P<0.05).Fourth,we compared the incidence and recurrence rate of complications.Three months after treatment,no significant difference was found in the incidence and recurrence rate of complications between the observation group(6.56%)and the control group(9.52%)(P>0.05).However,6 mo after treatment,the incidence and recurrence rate of complications in the observation group(2.91%)was significantly higher compared to that of the control group(12.69%)(P<0.05).Fifth,we compared patient satisfaction.Six months after treatment,the patient satisfaction of the observation group(93.43%)was significantly better than that of the control group(84.12%)(P<0.05).CONCLUSION Root canal therapy combined with nasal endoscopic surgery has a good therapeutic effect on severe odontogenic maxillary sinusitis caused by periapical periodontitis,and it can reduce the injury of maxillary sinus mucosa and bone,and significantly reduce the incidence of complications and recurrence rate.Meanwhile,it has high patient satisfaction and remarkable therapeutic effect,which is suggested to be popularized and applied in clinic.

Pulmonary embolism after shoulder surgery:Is it a real threat?

Pulmonary embolism(PE)is a rare but devastating complication of shoulder surgery.Apart from increased morbidity and mortality rates,it may significantly impair postoperative recovery and functional outcome.Its frequency accounts for up to 5.7%of all shoulder surgery procedures with a higher occurrence in women and patients older than 70 years.It is most commonly associated with thrombophilia,diabetes mellitus,obesity,smoking,hypertension,and a history of malignancy.PE usually occurs secondary to upper or lower-extremity deep vein thrombosis(DVT).However,in rare cases,the source of the thrombi cannot be determined.Prophylaxis for PE following shoulder surgery remains a topic of debate,and the standard of care does not routinely require prophylactic medication for DVT prophylaxis.Early ambulation and elastic stockings are important preventative measures for DVT of the lower extremity and medical agents such as aspirin,low-molecular-weight heparin,and vitamin K antagonists are indicated for high-risk patients,long-lasting operations,or concomitant severe acute respiratory syndrome coronavirus 2 infection.The most common symptoms of PE include chest pain and shortness of breath,but PE can also be asymptomatic in patients with intrinsic tolerance of hypoxia.Patients with DVT may also present with swelling and pain of the respective extremity.The treatment of PE includes inpatient or outpatient anticoagulant therapy if the patient is hemodynamically unstable or stable,respectively.Hemodynamic instability may require transfer to the intensive care unit,and cardiovascular arrest can be implicated in fatal events.An important issue for patients with PE in the postoperative period after shoulder surgery is residual stiffness due to a delay in rehabilitation and a prolonged hospital stay.Early physiotherapy and range-of-motion exercises do not adversely affect the prognosis of PE and are highly recommended to preserve shoulder mobility and function.

Gasless Laparoscopic Surgery plus Abdominal Wall Lifting for Giant Hiatal Hernia——Our Single-center Experience

Giant hiatal hernia（GHH） comprises 5% of hiatal hernia and is associated with significant complications.The traditional operative procedure,no matter transthoracic or transabdomen repair of giant hiatal hernia,is characteristic of more invasion and more complications.Although laparoscopic repair as a minimally invasive surgery is accepted,a part of patients can not tolerate pneumoperitoneum because of combination with cardiopulmonary diseases or severe posterior mediastinal and neck emphesema during operation.The aim of this article was to analyze our experience in gasless laparoscopic repair with abdominal wall lifting to treat the giant hiatal hernia.We performed a retrospective review of patients undergoing gasless laparoscopic repair of GHH with abdominal wall lifting from 2012 to 2015 at our institution.The GHH was defined as greater than one-third of the stomach in the chest.Gasless laparoscopic repair of GHH with abdominal wall lifting was attempted in 27 patients.Mean age was 67 years.The results showed that there were no conversions to open surgery and no intraoperative deaths.The mean duration of operation was 100 min（range：90–130 min）.One-side pleura was injured in 4 cases（14.8%）.The mean postoperative length of stay was 4 days（range：3–7 days）.Median follow-up was 26 months（range：6–38 months）.Transient dysphagia for solid food occurred in three patients（11.1%）,and this symptom disappeared within three months.There was one patient with recurrent hiatal hernia who was reoperated on.Two patients still complained of heartburn three months after surgery.Neither reoperation nor endoscopic treatment due to signs of postoperative esophageal stenosis was required in any patient.Totally,satisfactory outcome was reported in 88.9% patients.It was concluded that the gasless laparoscopic approach with abdominal wall lifting to the repair of GHH is feasible,safe,and effective for the patients who cannot tolerate the pneumoperitoneum.

Rare case of drain-site hernia after laparoscopic surgery and a novel strategy of prevention:A case report

BACKGROUND Trocar site hernia(TSH)is a rare but potentially dangerous complication of laparoscopic surgery,and the drain-site TSH is an even rarer type.Due to the difficulty to diagnose at early stages,TSH often leads to a delay in surgical intervention and eventually results in life-threatening consequences.Herein,we report an unusual case of drain-site TSH,followed by a brief literature review.Finally,we provide a novel,simple,and practical method of prevention.CASE SUMMARY A 54-year-old female patient underwent laparoscopic subtotal hysterectomy and bilateral adnexectomy for uterine fibroids 8 d ago in another hospital.She was admitted to our hospital with a 2-d history of intermittent abdominal pain,nausea,vomiting,and abdominal enlargement with an inability to pass stool and flatus.The emergency computed tomography scan revealed the small bowel herniated through a 10 mm trocar incision,which was used as a drainage port,with diffuse bowel distension and multiple air-fluid levels with gas in the small intestines.She was diagnosed with drain-site strangulated TSH.The emergency exploratory laparotomy confirmed the diagnosis.A herniorrhaphy followed by standard intestinal resection and anastomosis were performed.The patient recovered well after the operation and was discharged on postoperative day 8 and had no postoperative complications at her 2-wk follow-up visit.CONCLUSION TSH must be kept in mind during the differential diagnosis of post-laparoscopic obstruction,especially after the removal of the drainage tube,to avoid the serious consequences caused by delayed diagnosis.Furthermore,all abdomen layers should be carefully closed under direct vision at the trocar port site,especially where the drainage tube was placed.Our simple and practical method of prevention may be a novel strategy worthy of clinical promotion.

Multifactor study of efficacy and recurrence in laparoscopic surgery for inguinal hernia

BACKGROUND Inguinal hernia is a common clinical manifestation in children with a low selfhealing rate.AIM To determine the effect of laparoscopic surgery on indirect inguinal hernia and the risk factors for postoperative recurrence and to provide a reference for the clinical treatment and prevention of recurrence.METHODS We selected 360 children who underwent laparoscopic high ligation in our hospital as the laparoscopic group and 120 patients treated for inguinal hernia with conventional surgery as the control group.The operation time,blood loss,incision length,hospitalization time,total hospitalization cost and surgical complications were compared between the two groups.According to telephone follow-up or return visits,the children who had recurrence within 2 years after the operation in the laparoscopic group were analyzed,and the laparoscopic high ligation hernia sac level was analyzed by the logistic multifactor method.Ligation was used to treat recurrence in children with inguinal hernia.RESULTS The operation time,blood loss,length of incision,and length of hospital stay in the laparoscopic group were lower than those in the control group(P<0.05).The total hospitalization cost in the laparoscopic group was higher than that in the control group(P<0.05).The operative complication rate was 1.67%lower than that in the control group(12.50%)(P<0.05).In 360 children with laparoscopic high ligation of the hernia sac,14 patients had recurrence within 2 years after surgery.After analysis,14 cases in the recurrence group did not recur.The preoperative incarceration rate,inner ring diameter,ligature use and age difference were statistically significant(P<0.05).According to logistic regression multivariate analysis,an inner ring diameter≥1.0 cm,the use of an absorbable ligature line and age>3 years increased the risk of postoperative recurrence in children with inguinal hernia after laparoscopic high ligation of the hernia sac(P<0.05).CONCLUSION Laparoscopic surgery for indirect inguinal hernia in children has the advantages of low trauma and a rapid postoperative recovery.An inner ring diameter≥1.0 cm,the use of absorbable ligature,and age>3 years may increase the risk of recurrence after laparoscopic high ligation of the hernia sac.

Robotic Foregut Surgery: One Surgeon’s Experience with Nissen Fundoplication, Esophagomyotomy, and Hiatal Hernia Repair

Purpose: The purpose of the study was to review a single surgeon, seven-year experience, using the Da Vinci Telerobotic system performing 124 foregut operations. Methods: Data review from 2002-2009 including 71 Nissen fundoplications, 26 esophagomyotomies, and 27 hiatal hernia repairs was performed. Parameters collected included gender, age, body mass index (BMI), estimated blood loss (EBL), port set up time (PST), robot operating time (ROT), total case time (TCT), length of stay (LOS), complications, conversions, and resident involvement. Statistical analysis was con-ducted. Results: 124 foregut operations: 45 males, 79 females, mean age of 54.8 ± 16.7 (18 - 85) years, mean TCT 174.4 ± 45.0 (102 - 321) min. Nissen fundoplication: mean BMI of 30.8 ± 3.9 (22.4 - 46.8) kg/m2, EBL 30.2 ± 21.8 (5 - 100) ml, PST 32.3 ± 9 (14 - 63) min, ROT 111.4 ± 37.3 (51 - 229) min, TCT 175.0 ± 46.4 (102 - 321) min, median LOS 1 (0 - 9) day, complication rate 7.0% (5/71), conversion rate 5.6%, resident involvement 69.0% (49/71). Esophagomyotomy: mean BMI of 26.5 ± 6.1 (15.4 - 36.6) kg/m2, EBL 39.1 ± 41.7 (10 - 200) ml, PST 28.0 ± 8.6 (16 - 47) min, ROT 122.9 ± 45 (31 - 217) min, and TCT 178.0 ± 40.5 (105 - 262) min, median LOS 1 (0 - 6) day, complication rate 15.4% (4/26), conversion rate 0%, resident involvement 69.2% (18/26). Hiatal hernia repair: mean BMI of 28.4 ± 4.2 (21.9 - 36.8) kg/m2, EBL 38.4 ± 32.7 (10 - 150) ml, PST 28.8 ± 8.0 (17 - 52) min, ROT 109.0 ± 44.5 (49 - 250) min, and TCT 169.2 ± 46.5 (102 - 299) min, median LOS 1 (1 - 14) day, complication rate 11.1% (3/27), conversion rate 3.7%, resident involvement 66.7% (18/27). Conclusion: Robotic-assisted foregut surgery is safe and effective. This series compares favorably with other robotic studies in length of hospital stay, total case time, and complication and conver-sion rates. Foregut surgery is an excellent robotic training ground for residents.

Application of computer tomography-based 3D reconstruction technique in hernia repair surgery

BACKGROUND Hernia is a common condition requiring abdominal surgery.The current standard treatment for hernia is tension-free repair using meshes.Globally,more than 200 new types of meshes are licensed each year.However,their clinical applications are associated with a series of complications,such as recurrence(10%-24%)and infection(0.5%-9.0%).In contrast,3D-printed meshes have significantly reduced the postoperative complications in patients.They have also shortened operating time and minimized the loss of mesh materials.In this study,we used the myopectineal orifice(MPO)data obtained from preoperative computer tomography(CT)-based 3D reconstruction for the production of 3D-printed biologic meshes.AIM To investigate the application of multislice spiral CT-based 3D reconstruction technique in 3D-printed biologic mesh for hernia repair surgery.METHODS We retrospectively analyzed 60 patients who underwent laparoscopic tension-free repair for inguinal hernia in the Department of General Surgery of the First Hospital of Shanxi Medical University from September 2019 to December 2019.This study included 30 males and 30 females,with a mean age of 40±5.6 years.Data on the MPO were obtained from preoperative CT-based 3D reconstruction as well as from real-world intraoperative measurements for all patients.Anatomic points were set for the purpose of measurement based on the definition of MPO:A:The pubic tubercle;B:Intersection of the horizontal line extending from the summit of the inferior edge of the internal oblique and transversus abdominis and the outer edge of the rectus abdominis,C:Intersection of the horizontal line extending from the summit of the inferior edge of the internal oblique and transversus abdominis and the inguinal ligament,D:Intersection of the iliopsoas muscle and the inguinal ligament,and E:Intersection of the iliopsoas muscle and the superior pubic ramus.The distance between the points was measured.All preoperative and intraoperative data were analyzed using the t test.Differences with P<0.05 were considered significant in comparative analysis.RESULTS The distance between points AB,AC,BC,DE,and AE based on preoperative and intraoperative data was 7.576±0.212 cm vs 7.573±0.266 cm,7.627±0.212 cm vs 7.627±0.212 cm,7.677±0.229 cm vs 7.567±0.786 cm,7.589±0.204 cm vs 7.512±0.21 cm,and 7.617±0.231 cm vs 7.582±0.189 cm,respectively.All differences were not statistically significant(P>0.05).CONCLUSION The use of multislice spiral CT-based 3D reconstruction technique before hernia repair surgery allows accurate measurement of data and relationships of different anatomic sites in the MPO region.This technique can provide precise data for the production of 3D-printed biologic meshes.

Preoperative calculation of angles of vision and working area in laparoscopic surgery to treat a giant hiatal hernia

BACKGROUND Giant hiatal hernias still pose a major challenge to digestive surgeons,and their repair is sometimes a highly complex task.This is usually performed by laparoscopy,while the role of the thoracoscopic approach has yet to be clearly defined.AIM To preoperatively detect patients with a giant hiatal hernia in whom it would not be safe to perform laparoscopic surgery and who,therefore,would be candidates for a thoracoscopic approach.METHODS In the present study,using imaging test we preoperatively simulate the field of vision of the camera and the working area(instrumental access)that can be obtained in each patient when the laparoscopic approach is used.RESULTS From data obtained,we can calculate the access angles that will be obtained in a preoperative computerised axial tomography coronal section,according to the location of the trocar.We also provide the formula for performing the angle calculations If the trocars are placed in loss common situations,thus enabling us to determine the visibility and manoeuvrability for any position of the trocars.CONCLUSION The working area determines the cases in which we can operate safely and those in which certain areas of the hernia cannot be accessed,which is when the thoracoscopic approach would be safer.

Percutaneous Endoscopic Lumbar Spine Surgery for Lumbar Disc Herniation and Lumbar Spine Stenosis: Emphasizing on Clinical Outcomes of Transforaminal Technique

Lumbar Disc Herniation and Lumbar Spine Stenosis are the most common spine diseases which are mainly due to age related Spine degeneration. Diagnosis of both Lumbar Disc Herniation and Lumbar Spine Stenosis depends on clinical findings as well as radiological investigations. Treatment of choice of these conditions is on the basis of the patient conditions. Surgical treatment is the option only when the conservative treatment does not improve the patient’s clinical condition. Advancement and improvement of the technology have resulted in the traditional open surgical treatment into minimal invasive surgery. Intervention of the different surgical instruments with expert spinal surgeons had made percutaneous endoscopic lumbar Spine surgery as one of the preferred choices of surgery for treating Lumbar Disc Herniation and Lumbar Spine Stenosis. The concept of percutaneous endoscopic surgery for lumbar region is to provide surgical options without producing iatrogenic morbidity associated with the open surgical procedures. Conventionally, there are different approaches/techniques for Percutaneous Endoscopic Lumbar Spine Surgery, but in this review we are mainly focusing on the Transforaminal Technique. Regarding the Lumbar Disc Herniation treatment with transforaminal approach, a number of articles have been published due to which we mainly focused on those articles which were published after 2009 onwards. While fewer articles related to Lumbar Spine Stenosis treatment with Transforaminal approach were found, we tried to brief out all those articles. On the basis of comparative study of different surgeries done for Lumbar Disc Herniation and Lumbar Spine Stenosis, Percutaneous Transforaminal endoscopic Lumbar Surgery provides a substantial benefit.

Abscess in the inguinal hernial sac after peritonitis surgery: A case report

In this paper, we report an extremely rare case of an abscess that developed in the inguinal hernial sac after surgery for peritonitis. A 60-year-old man underwent laparoscopic low anterior resection for rectal cancer. One day after this operation, peritoneal drainage and ileostomy were performed for rectal anastomotic leakage. Five days after the second operation, computed tomography revealed an abscess in the left inguinal hernial sac. Subsequently, hernioplasty and resection of the inflamed sac were performed.
