In the pre-surgical physical examination, unilateral inguinal hernias were found in 76.6 % and bilateral in 23.3 %; in most of the patients the hernias were primary in 86.6 % and recurred in 13.3 %. Average surgical time was 93.1 minutes; with a maximum time of 120 minutes and a minimum of 60 minutes. The hospitalization time in 100 % of the patients was 48 hours. Of the post-operative complications, it is established that 76.6% did not present any type of complication; 20 % presented seroma as the main complication and 3.3 % surgical site infection. Conclusion: due to its high frequency and its impact on work and social disability, inguinal hernias represent one of the most important surgical pathologies with low rates of postoperative complications and short hospital stay.

Preliminary experience of suprapubic three-arm robot-assisted laparoscopic radical prostatectomy / 中华泌尿外科杂志

To evaluate the feasibility and safety of suprapubic three-arm robot-assisted laparoscopic radical prostatectomy (STA-RLRP). Fifteen patients with prostatic cancer underwent STA-RLRP. All the 15 procedures were completed successfully, without the need for ancillary trocars or additional instruments. No patient required conversion to standard laparoscopy or open surgery. STA-RLRP is feasible and safe with good short-term tumor control, satisfactory recovery of urinary control function and good cosmetic outcome, which is worthy of clinical application.

Comparison of modified laparoscopic total extraperitoneal hernia repair and laparoscopic transabdominal preperitoneal hernia repair in patients with inguinal hernia / 中国医师进修杂志

Objective:To explore the application effects of modified laparoscopic total extraperitoneal hernia repair (TEP) and laparoscopic transabdominal preperitoneal hernia repair (TAPP) in inguinal hernia.Methods:One hundred and twenty-five patients with inguinal hernia in Yiwu Central Hospital from February 2017 to December 2019 were selected for retrospective study. They were divided into modified TEP group (63 cases) and TAPP group (62 cases). The modified TEP group was treated with modified TEP, and the TAPP group was treated with TAPP. The perioperative operation related indexes, serum oxidative stress indexes, 1-year recurrence rate and semen quality indexes were compared between the two groups.Results:The scores of visual analogue scale after operation for 24 h in the modified TEP group was lower than that in the TAPP group: (1.68 ± 0.39) scores vs. (1.97 ± 0.46) scores, P<0.05. After operation for 3 d, the levels of serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) in the modified TEP group were higher than those in the TAPP group: (92.79 ± 8.82) μmol/L vs. (84.40 ± 7.36) μmol/L, (81.52 ± 9.37) U/L vs. (75.75 ± 8.50) U/L; and the level of malondialdehyde (MDA) in the modified TEP group was lower than that in the TAPP group: (23.42 ± 3.3) μmol/L vs. (26.71 ± 3.92) μmol/L; the differences were statistically significant ( P<0.05). There was no significant difference in 1-year recurrence rate between the two groups ( P>0.05). One year after operation, the levels of acid phosphatase (ACP), fructose (FRU) and α- glucosidase (α- Glu) in the modified TEP group were higher than those in the TAPP group: (180.87 ± 20.15) kU/L vs. (159.85 ± 14.50) kU/L, (3.37 ± 0.84) g/L vs.(2.53 ± 0.67) g/L, (62.94 ± 6.25) kU/L vs. (43.96 ± 5.31) kU/L, the differences were statistically significant ( P<0.05). Conclusions:Both modified TEP and TAPP are effective methods for the treatment of inguinal hernia, but the former can reduce surgical trauma, recover quickly, and protect normal reproductive function.

Advances in clinical application of laparoscopic totally extraperitoneal herniorraphy / 中华消化外科杂志

Based on literatures in recent years and combined with clinical practice, the authors explore the advances in clinical application of laparoscopic TEP.

Clinical application of a Kirschner wire assisted double-hook water-injection hernia needle in complicated pediatric oblique inguinal hernia / 中华实用儿科临床杂志

Objective:To explore the clinical value of single-hole laparoscopic percutaneous extraperitoneal closure operation using a Kirschner wire assisted double-hook water-injection hernia needle in treating complicated pediatric oblique inguinal hernia.Methods:The clinical data of 366 children with oblique inguinal hernia treated in the Department of Urology Surgery, Children′s Hospital of Nanjing Medical University from December 2020 to October 2021 were retrospectively analyzed.According to the surgical methods, the children were divided into the ordinary crochet needle group and the Kirschner wire assisted group.Children treated by a single-port laparoscopic double hook water-injection hernia crochet needle (309 cases) were classified into the ordinary crochet needle group.Children treated by a single-port laparoscopic Kirschner wire assisted double hook water-injection hernia crochet needle (57 cases) were included in the Kirschner wire assisted group.The independent sample t-test and rank sum test was used to compare the relevant clinical indicators between the two groups. Results:Compared with the ordinary crochet needle group, children in the Kirschner wire assisted group were younger at surgery[(2.87±1.88) years vs.(4.91±2.39) years] and had larger hernia sacs [17 303.89(8 622.49, 37 295.42) mm 3vs.9 650.97(3 849.24, 17 539.51) mm 3]. The differences in the age at surgery and hernia sac volume were statistically significant ( t=-5.407, Z=-4.218; all P<0.001). There was no significant difference in body mass index between the 2 groups ( P>0.05). Taking hernias with sac volume >10 000 mm 3 as huge hernias, there were 70.18%(40/57 cases) and 47.25%(146/309 cases) of huge hernias in the Kirschner wire assisted group and the ordinary crochet needle group, respectively.The overall operation time of the Kirschner wire assisted group was significantly longer than that of the ordinary crochet needle group[(20(15, 20) min vs.15(15, 20) min] ( Z=-2.842, P<0.05). However, the operation time for huge oblique hernias with sac volume >10 000 mm 3 was not statistically significant between the 2 groups ( P>0.05). No recurrence in both groups was found during 6-16 months of follow-up. Conclusions:For complicated oblique inguinal hernia in children with a huge hernia or obvious retroperitoneal folds at the internal ring and heavy scar adhesion between the hernia sac and abdominal wall, the insertion of a Kirschner wire can help the hernia crochet needle to traverse the vas de-ferens and spermatic cord vessels smoothly.As a single port laparoscopic operation, the Kirschner wire assisted hernia crochet needle requires no addition of trocar holes and leaves only a small surgical scar.With good feasibility and safety, it is applicable for clinical popularization.

Concept of 3D membrane anatomy in extraperitoneal laparoscopic radical cystectomy: preliminary application / 中华泌尿外科杂志

Objective:To explore the clinical feasibility of extra-peritoneal laparoscopic radical cystectomy based on the concept of 3D membrane anatomy.Methods:The clinical data of 10 male patients with bladder cancer who underwent 3D extra-peritoneal laparoscopic radical cystectomy + ileal-orthotopic-neobladder surgery from October 2020 to June 2021 were retrospectively analyzed. The median age was 67 years. The ASA score was 1-2 in 8 cases and 3 in 2 cases. There were 4 cases of hypertension, 2 cases of diabetes, 1 case of heart disease, no case of abdominal surgery history. During the operation, the concept of 3D membrane anatomy was used to identify the important fascia in the pelvic cavity and to find the key layers and structures in the pelvic cavity.It was separated from the prevesical fascia to the laterovesical space, and confluenced with Retzius space and Bogros space. It was dissected in the layer surrounded by the prevesical fascia, the vesicohypogastric fascia, and the urogenital fascia to complete the process of cystectomy.Results:The operations of 10 patients were completed successfully and there was no conversion to open operation. The median operation time was 276(237-325) minutes, and the median blood loss was 160(50-280)ml. The postoperative bowel recovery median time was 1.8(1-3)days, and the patients were out of bed about 1.3(1-2) days. The median postoperative hospital stay was 9(5-12) days. The number of median lymph node dissection in all patients was 10(6-20). Positive lymph nodes was found in 3 cases. Positive margin was found in no case. Postoperative tumor pathological stages were T 2 stage in 7 cases, T 3 stage in 3 cases. During the follow-up, all patients had no obvious complications. Conclusions:It is feasible to apply the concept of 3D membrane anatomy to identify and locate the key fascia structures and levels in extra-peritoneal laparoscopic radical cystectomy. The operative complications were less and the postoperative recovery was faster. The anatomy is clear during the operation, which has good safety and reduces the difficulty of the operation.

Rectal damage control: when to do and not to do / Control de daños de recto: que hacer y que no hacer

Abstract Rectal trauma is uncommon, but it is usually associated with injuries in adjacent pelvic or abdominal organs. Recent studies have changed the paradigm behind military rectal trauma management, showing better morbidity and mortality. However, damage control techniques in rectal trauma remain controversial. This article aims to present an algorithm for the treatment of rectal trauma in a patient with hemodynamic instability, according to damage control surgery principles. We propose to manage intraperitoneal rectal injuries in the same way as colon injuries. The treatment of extraperitoneal rectum injuries will depend on the percentage of the circumference involved. For injuries involving more than 25% of the circumference, a colostomy is indicated. While injuries involving less than 25% of the circumference can be managed through a conservative approach or primary repair. In rectal trauma, knowing when to do or not to do it makes the difference.

Resumen El trauma de recto es poco frecuente, pero generalmente se asocia a lesiones de órganos adyacentes en la región pélvica y abdominal. Estudios recientes han cambiado los paradigmas del manejo tradicional derivados del trauma militar, mostrando mejores resultados en la morbilidad y mortalidad. Sin embargo, las técnicas de control de daños en el trauma rectal aún son controvertidas. El objetivo de este articulo es proponer el algoritmo de manejo del paciente con trauma rectal e inestabilidad hemodinámica, según los principios de la cirugía de control de daños. Se propone que las lesiones del recto en su porción intraperitoneal sean manejadas de la misma manera que las lesiones del colon. Mientras que el manejo de las lesiones extraperitoneales del recto dependerá del compromiso de la circunferencia rectal. Si es mayor del 25% se recomienda realizar una colostomía. Si es menor, se propone optar por el manejo conservador o el reparo primario. Saber que hacer o que no hacer en el trauma de recto marca la diferencia.

Application of membrane anatomy theory in totally extraperitoneal inguinal hernia repair / 中华胃肠外科杂志

Trocar placement and camera-dissection in the midline is the most commonly applied method for total extraperitoneal inguinal hernia repair (TEP), for which the theory of membrane anatomy has guiding significance. We hereby applies the theories and concepts, such as "fascia lining", "multi-layer", "inter-fascial planes", "combined inter-fascial plane" and "plane transition", to elucidate the key steps of TEP, for instance, space creation, hernia sac dissection, mesh flattening. Camera-dissection is performed along the posterior sheath of the rectus abdominis. Firstly, the camera enters retro-rectus space locating between the rectus abdominis and the transversalis fascia (TF). There are inferior epigastric vessels and their branches in the retro-rectus space, thus over-dissection should be avoided. Secondly, the camera goes downward through the TF into the pre-peritoneal space. The pre-peritoneal space is divided into the parietal plane and visceral plane by pre-peritoneal fascia (PPF). Both bladder and spermatic cord components locate on the visceral plane. Dissection of the median area should be implemented on the parietal plane, namely "surgical space", to protect the bladder. The parietal plane is the "holy plane" of TEP. Dissection of the indirect hernia area should be implemented on the visceral plane, namely "anatomical space", to protect the spermatic cord components. The reduction of direct hernia could be understood as the easy separation of TF and PPF. The reduction of indirect hernia is relatively difficult separation of peritoneum and spermatic cord components. During the transition of parietal and visceral planes, PPF (especially the pre-peritoneal loop) should be dissected for complete parietalization, in order to flatten the mesh.

A comparison of perioperative outcomes between extraperitoneal robotic single-port and multiport radical prostatectomy with the da Vinci Si Surgical System / 亚洲男科学杂志(英文版)

To evaluate outcomes between extraperitoneal robotic single-port radical prostatectomy (epR-spRP) and extraperitoneal robotic multiport radical prostatectomy (epR-mpRP) performed with the da Vinci Si Surgical System, comparison was performed between 30 single-port (SP group) and 26 multiport (MP group) cases. Comparisons included operative time, estimated blood loss (EBL), hospital stay, peritoneal violation, pain scores, scar satisfaction, continence, and erectile function. The median operation time and EBL were not different between the two groups. In the SP group, the median operation time of the first 10 patients was obviously longer than that of the latter 20 patients (P < 0.001). The median postoperative hospital stay in the SP group was shorter than that in the MP group (P < 0.001). The rate of peritoneal damage in the SP group was less than that in the MP group (P = 0.017). The pain score and overall need for pain medications in the SP group were lower than those in the MP group (P < 0.001 and P = 0.015, respectively). Patients in the SP group were more satisfied with their scars than those in the MP group 3 months postoperatively (P = 0.007). At 3 months, the cancer control, recovery of erectile function, and urinary continence rates were similar between the two groups. It is safe and feasible to perform epR-spRP using the da Vinci Si surgical system. Therefore, epR-spRP can be a treatment option for localized prostate cancer. Although epR-spRP still has a learning curve, it has advantages for postoperative pain and self-assessed cosmesis. In the absence of the single-port robotic surgery platform, we can still provide minimally invasive surgery for patients.

Objective@#To assess the feasibility and validity of the establishment of a modified channel for extraperitoneal robot-assisted laparoscopic radical prostatectomy (RARP) through single incision.@*METHODS@#From November 2020 to January 2021, 35 cases of localized PCa were treated by extraperitoneal RARP through single incision in our center. All the operations were performed by the same surgeon, none via the multichannel port for the establishment of the channel. We recorded and analyzed the intra- and postoperative parameters, operation cost, complications, pathological findings and follow-up data.@*RESULTS@#All the operations were successfully completed, without conversion to open surgery or additional channels, or serious postoperative complications, the time for establishing the extraperitoneal space averaging 25.4 (20.0－45.0) min, the operation time 67.3 (35.0－125.0) min, intraoperative blood loss 75.5 (60.0－150.0) ml, time to first postoperative anal exhaust 26 (8－48) h, and postoperative hospital stay 7.89 (7－10) d. Postoperative pathology showed adenocarcinoma in all the cases, with Gleason score (GS) 3+3 in 9 (25.7%), GS 3+4 in 9 (25.7%), GS 4+3 in 8 (22.9%), and GS ≥ 8 in 9 (25.7%) of the cases, 23 (65.7%) in the

Femoral hernia: uncommon, but associated with potentially severe complications / Hérnia femoral: incomum, mas associada a complicações potencialmente graves

ABSTRACT Background: Although the laparoscopic access is becoming the preferable treatment for femoral hernia, there are only few studies on this important subject. Aim: To assess the outcomes of the totally extraperitoneal laparoscopic (TEP) access in the treatment of femoral hernia. Methods: Data of 62 patients with femoral hernia who underwent herniorrhaphy were retrospectively reviewed. The diagnosis of femoral hernia was established by clinical and/or imaging exams in 55 patients and by laparoscopic findings in seven. Results: There were 55 (88.7%) females and 7 (11.3%) males, with female to male ratio of 8:1. The mean age was of 58.9±15.9 years, ranging from 22 to 92 years. Most patients (n=53; 85.5%) had single hernia and the remaining (n=9; 14.5%) bilateral, making a total of 71 hernias operated. Prior lower abdominal operations were recorded in 21 (33.9%) patients. Conversion to laparoscopic transabdominal preperitoneal procedure was performed in four (6.5%). Open herniorrhaphy was needed in two (3.2%), one with spontaneous enterocutaneous fistula in the groin region (Richter's hernia) and the another with incidental perforation of the adjacent small bowel that occurred during dissection of hernia sac. There was no mortality. Conclusion: Femoral hernia is uncommon, and it may be associated with potentially severe complications. Most femoral hernias may be successfully treated with totally extraperitoneal laparoscopic access, with low conversion and complication rates.

RESUMO Racional: Embora o acesso laparoscópico esteja se tornando o tratamento preferencial para a hérnia femoral, poucos são os estudos sobre esse importante assunto. Objetivo: Avaliar os resultados do acesso laparoscópico totalmente extraperitoneal no tratamento da hérnia femoral. Métodos: Os dados de 62 pacientes com hérnia femoral que foram submetidos a herniorrafia foram revisados ​​retrospectivamente. O diagnóstico foi estabelecido por exames clínicos e/ou de imagem em 55 pacientes e por achados laparoscópicos em sete. Resultados: Havia 55 (88,7%) mulheres e 7 (11,3%) homens, com proporção feminino/masculino de 8: 1. A média de idade foi de 58,9±15,9 anos (22-92). A maioria (n=53, 85,5%) apresentava hérnia única e o restante (n=9, 14,5%) bilaterais, perfazendo um total de 71 hérnias femorais operadas. Operações prévias no abdome inferior foram registradas em 21 (33,9%) pacientes. A conversão para procedimento pré-peritoneal transabdominal laparoscópico foi realizada em quatro (6,5%). Herniorrafia aberta foi necessária em dois pacientes (3,2%), um com fístula enterocutânea espontânea na região da virilha (hérnia de Richter) e o outro com perfuração incidental do intestino delgado adjacente que ocorreu durante a dissecção do saco herniário. Não houve mortalidade. Conclusão: A hérnia femoral é incomum e pode estar associada a complicações potencialmente graves. A maioria das hérnias femorais pode ser tratada com sucesso através do acesso laparoscópico totalmente extraperitoneal, com baixas taxas de conversão e complicações.

A study of incidence of inguinodynia in inguinal hernias repair at a tertiary center

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.

Closed loop small bowel obstruction due to mid urethral sling mesh

Closed loop small bowel obstruction is a surgical emergency, which when left untreated leads to vascular compromise resulting in intestinal ischemia, necrosis and perforation. We report the case of a 61 years old female with past surgical history of hysterectomy and a mid-urethral sling, who presented to the emergency department for abdominal pain and obstipation. She was found on imaging to have a closed loop small bowel obstruction. An exploratory laparotomy revealed an adhesive band encompassing the distal terminal ileum, visceral peritoneum and the Mid‐urethral slings mesh. This is a rare complication that, to our knowledge, has not been reported in the surgical literature. This paper will discuss the clinical presentation, diagnostic studies, therapeutic intervention and outcome of this unique case.

Extraperitoneal cesarean section: a retrospective analysis

Background: Morbidity of caesarean section still persist in terms of pain, infection and adhesion. This study will focus on different morbidities associated with ECS.Methods: A retrospective analysis of 29 ECS were included from June to September 2018, done at Midnapore Medical college, West Bengal, India.Results: Contracted pelvis (12/29, 41.37%) and cephalopelvic disproportion (10/29,34.48%) were common indications for ECS. Mean gestational age was 39.65±1.31 weeks and birth weight were 3.01±0.40 kg. Time taken for ECS was 33.06±10.85 minutes. Extension of uterine incision and mild distension of abdomen occurred in 3.44% each. Post-operative period was uneventful and all discharged after 72 hours of operation.Conclusions: ECS can be performed safely by experienced hands with less feto-maternal morbidity and early discharge of mother and baby.

Extraperitoneal versus transperitoneal cesarean section: a retrospective analysis

Background: Cesarean section is becoming a more common delivery type worldwide. The objective of this study was to compare surgical morbidity in extraperitoneal versus transperitoneal techniques of cesarean section.Methods: A total of 60 patients was included in this study out of which 30 underwent extraperitoneal cesarean section(ECS) and 30 patients underwent transperitoneal cesarean section (TCS) and compared both the techniques with respect to nausea or vomiting intra-operatively, pain score (as measured by visual analogue scale) post operatively, return of bowel function and blood loss.Results: Intra-operative nausea and vomiting was noted in 33.34% of patients in TCS group while none of the patients in ECS group had any such complaints. No difference was noted in average blood loss between the 2 groups. Post-operative pain in ECS was 4.13 as compared to 6.86 in TCS. Return of bowel sounds in ECS group was much earlier (5.46 hours) as compared to TCS group (11.33 hours).Conclusions: We conclude that extraperitoneal technique is advantageous over transperitoneal approach. Decreased nausea and vomiting, early return of bowel function in the post-operative period, decreased post-operative pain allowing early feeding and mobilization are definite benefits of this technique. This further helps in making a relatively smoother post-operative recovery.

The application and outcomes of C.R.P.C.four-step radical prostatectomy under extraperitoneal laparoscopy / 中华泌尿外科杂志

Objective To summarize the preliminary experience of extraperitoneal laparoscopic radical prostatectomy (C.R.P.C.four-step) for localized prostate cancer and the outcomes based on early follow-up.Methods A total of 102 prostate cancer patients were screened by prostate specific antigen (PSA) and diagnosed by prostate magnetic resonance imaging and prostatic puncture biopsy with cT1c-cT3b,with average age of (67 ±5) years old,average preoperative total PSA value of (45.32 ± 18.33) ng/ml,and average prostate volume was (42 ± 12)cm3.All these patients underwent extraperitoneal laparoscopic radical prostatectomy by the four-step technique,abbreviating as C.R.P.C.[C:control DVC (dorsal deep venous complex).R:recognize three anatomical layers (prostate and bladder junction,seminal vesicle,and Denonvilliers' fascia surface).P:preserve urethral sphincter and bladder neck.C:continuous anastomosis between urethra and bladder neck (4 key needles at 3,5,7 and 9 o'clock)].The operative time,estimated blood loss,length of hospital stay and postoperative complications were recorded,and the postoperative PSA was followed up.Results All the 102 cases were successfully treated by iaparoscopic radical prostatectomy.The operative time was from 55 to 156 min (mean 92 min),and the estimated blood loss was from 55 to 185 ml (mean 105 ml).There was no case converted of open surgery,only one case received blood transfusion for postoperative hemorrhage (0.98％),and positive surgical margin was found in 15 case (14.70％) by pathological examination.Postoperative urinary extravasation within one week occurred in 2 (1.96％) cases,and resolved after tensioning the catheter and prolonging the indwelling time.During the follow-up period of 12 to 45 months,2 cases were incontinent (grade I-II),and the other cases(98.04％) had no incontinence or dysuria.However,11 cases (10.78％) developed to biochemical recurrence within 6 months after the operation.Conclusions The C.R.P.C.four-step technique of lparoscopic radical prostatectomy is easily to be grasped and performed by the greenhand urologists,and was efficient and safe.

Behavior of free omental grafts without vascular anastomosis implanted in cats experimental wounds / Comportamento do enxerto omental livre sem anastomose vascular implantado em feridas experimentais de gatos

ABSTRACT: It is known that skin healing in cats is slower and has a higher complication rate than in dogs, what leads to search for new resources to enhance this process. Omentum properties in the aid of tissue repair are known and, among the forms of extraperitoneal omentalization, the use of free omental grafts without vascular anastomosis is advantageous, but little studied; there is no knowledge about its effect on skin healing, nor if it's still viable when implanted in the subcutaneous space. Thus, the present study aimed to describe possible alterations produced by free omental graft without anastomosis inserted in the subcutaneous space, by means of macroscopic clinical analysis of the implantation region in cats. Twenty intact female cats were divided into two groups (Group 1: treated animals; Group 2: controls) of similar size. All animals were subjected to ovariosalpingohysterectomy (OSH) prior to the induction of an experimental wound for the implantation of the omental graft. Wounds were evaluated on days 1, 2, 4, 8, and 15 postsurgery and then weekly until no lesions were noted. Data regarding color, consistency, presence or absence of crusts, wound resistance, and volume measurements were recorded. There was activation of the omentum on the 4th day of evaluation with reduction of hemorrhage and an increase in the resistance to traction of the experimental wound. We concluded that the omentum without vascular anastomosis is capable of maintaining its viability and exert positive influence on the repair process without showing deleterious signs on the implantation site.

RESUMO: Sabe-se que a cicatrização de pele em gatos é mais lenta e apresenta índice maior de complicações que nos cães, dai a importância da busca de novos recursos para estimular o processo cicatricial. São conhecidas as propriedades do omento no auxílio ao reparo tecidual e, dentre as formas de omentalização extraperitoneal, o uso do omento livre sem anastomose vascular é vantajoso, porém pouco estudado; não há conhecimento sobre seu efeito na cicatrização cutânea, tampouco se permanece viável quando implantado no espaço subcutâneo. Sendo assim, o presente trabalho tem como objetivo avaliar possíveis alterações produzidas pelo enxerto omental livre sem anastomose inserido no espaço subcutâneo, por meio da avaliação clínica macroscópica da região de implantação em gatos. Foram utilizadas 20 gatas, de idade entre um e sete anos, sem alterações em exame de sangue, FIV/FELV negativas. Os animais foram divididos em dois grupos (Tratado e Controle) de igual tamanho, diferindo quanto à utilização do enxerto de omento livre. Foi realizada cirurgia de ovariossalpingohisterectomia (OSH) em todos os animais, previamente à criação da ferida experimental para implantação ou não do enxerto omental. As feridas foram avaliadas nos dias 1, 2, 4, 8 e 15 do pós-operatório e a partir de então semanalmente, até nenhuma alteração ser observada. Foram anotados dados referentes à coloração, consistência, presença de crosta, resistência da ferida e medidas do volume. Nos resultados destacou-se a ativação do omento no quarto dia de avaliação, observada pelo aumento de volume, com redução de hemorragia e aumento na resistência da ferida experimental à tração. Conclui-se que o omento em sua forma livre sem anastomose é capaz de manter sua viabilidade e exercer influência positiva sobre o processo de reparo, sem demonstrar sinais deletérios sobre a região implantada.

A Rare Case of Posterior Horseshoe Abscess Extending to Anterolateral Extraperitoneal Compartment: Anatomical and Technical Considerations

Perianal abscess and fistula are 2 distinct entities that share a common pathology. A horseshoe fistulous abscess, a complex type of these conditions, occurs when the suppurative inflammation spreads through the deep anal space to the bilateral ischiorectal fossae. Following the intersphincteric plane, this infection may extend to the pararectal space, forming a supralevator abscess. We present a very rare case involving a 52-year-old male patient who was admitted to our surgical department with an extraperitoneal purulent inflammation as a complication following multiple drainage procedures for a posterior horseshoe abscess. Emphasis is given to the anatomical and technical considerations of eradication of anorectal sepsis and the management of complex fistula-in-ano along with a concise review of the literature.

Clinical significance of laparoscopic extraperitoneal abdominal para-aortic lymphadenectomy / 中国实用妇科与产科杂志

OBJECTIVE: To evaluate the clinical significance of laparoscopic extraperitoneal para-aortic lmphadenectomy(PAL)in high para-aortic lymphadenectomy.METHODS: A non-randomized controlled method was used to analyze the clinical data of laparoscopic extraperitoneal PAL in 35 patients(extraperitoneal group)and laparoscopic transabdominal PAL in 40 patients(transabdominal group)in the Gynecological Department of the First Affiliated Hospital of Xiamen University from March 2018 to April 2019.RESULTS: All the 35 cases of laparoscopic extraperitoneal PAL reached the level of renal vein.Endometrial cancer accounted for the largest proportion,with an average age of 47.57 years and an average body mass index of 23.77.The average operation time was 109 minutes in the first 6 cases and 74.73 minutes in the other 29 cases.The amount of hemorrhage was 15.19 mL,and the average number of para-aortic lymph nodes(PALN)resected was 17.87.There were 5 cases of positive PALN metastasis,and the average gastrointestinal recovery time was13.43 hours.The average postoperative pelvic drainage was 76.57 hours and the average postoperative hospital stay was8.24 days.Intraoperative and postoperative complications included 1 case of inferior vena cava rupture,1 case of chyle leakage,and 1 case of vulvar edema.None of the 40 cases of laparoscopic transabdominal PAL reached the level of renal vein,and endometrial cancer accounted for the largest proportion,with the average age of 46.78 years and the average body mass index of 24.03.The average operation time was 90.55 min;the average intraoperative blood loss was 67.40 mL The average number of para-aortic lymph nodes was 3.30.There was one case of PALN metastasis.The average gastrointestinal recovery time was 22.35 hours,and the average postoperative pelvic drainage time was 75.75 hours.The average length of hospital stay was 8.90 days.There were 2 cases of rupture of the inferior mesenteric artery,3 cases of chyle leakage,and 2 cases of vulvar edema.The number of PALN resection,intraoperative blood loss,and operation time in the extraperitoneal group were not related to the body mass index,but the number of PALN in obese patients in the laparoscopic transabdominal group was significantly reduced,the operation time was longer,the intraoperative blood loss was more,and postoperative gastrointestinal recovery time is longer(P<0.05).CONCLUSION: Laparoscopic extraperitoneal PAL can solve the problems of laparoscopic transabdominal PAL lymph node resection,which is difficult to reach the level of renal vein,intraoperative intestinal tube interference,and the number of lymph nodes resected.It is especially suitable for obese patients.Laparoscopic extra-peritoneal high-grade PAL is safe,feasible,and recommended.
