Primary saphenous vein insufficiency:prospective studies on diagnostic duplex ultrasonography and treatment with endovenous radiofrequency-resistive heating

Abstract The purpose of the present research was (I-II) to evaluate the effects of clinical, hand-held Doppler (HHD) and duplex ultrasonographic examinations on the planning of operative procedure for primary varicose veins, (III) to assess the feasibility, safety and efficacy of endovenous saphenous vein obliteration with radiofrequency-resistive heating and (IV) to compare endovenous saphenous vein obliteration with conventional stripping operation in terms of short-term recovery and costs. Sixty-two legs (in 49 consecutive patients) and 142 legs (in 111 consecutive patients) with primary uncomplicated varicose veins were examined clinically and with HHD and duplex ultrasonography for planning the subsequent treatment. At the saphenous-femoral junction (SFJ) and at the saphenous-popliteal junction (SPJ), sensitivity was 56-64% and 23%, specificity 93-97% and 96%, positive predictive value 97-98% and 43% and negative predictive value 44-45% and 91%, respectively. In 9% of the cases, the treatment plan was modified on the basis of the duplex ultrasound findings. The present study showed that, in primary uncomplicated varicose veins, the accuracy of HHD is unsatisfactory. Thirty legs of 27 patients with varicose veins were treated using an endovenous catheter (Closure® System, VNUS Medical Technologies, Inc., Sunnyvale, CA), which was inserted under ultrasound guidance via a percutaneous puncture or a skin incision. The persistence of vein occlusion and complications potentially attributable to the endovenous treatment were assessed at 1-week, 6-week, 3-month, 6-month and 1-year follow-up visits. By the time of the last follow-up visit, occlusion of the treated segment of the LSV had been achieved in 22 (73.3%) legs. Persisting patency or recanalization of LSV was detected in 8 legs (26.7%). Postoperative complications included saphenous nerve paresthesia in 3 legs (10%) and thermal skin injury in one limb (3.3%). Twenty-eight selected patients admitted for operative treatment of varicose veins in the tributaries of the primary long saphenous were randomly assigned to endovenous obliteration (n = 15) or stripping operation (n = 13). The patients were followed up for 7-8 weeks postoperatively and examined by duplex ultrasonography. The comparison of costs included both direct medical costs and costs due to lost of productivity. All operations were successful, and the complication rates were similar in the two groups. The sick leaves were significantly shorter in the endovenous obliteration group [6.5 (SD 3.3) vs. 15.6 (SD 6.0), 95 % CI 5.4 to 12.9, p < 0.001, t-test]. When the value of the lost working days was included, the endovenous obliteration was societally cost-saving

Vatsaontelon sulkeminen:miten ehkäisen arpityrän?

Tiivistelmä Suomessa leikataan vuosittain noin 1 650 arpityrää. Euroopan Tyräyhdistys (European Hernia Society, EHS) julkaisi vuonna 2015 laajaan kirjallisuuskatsaukseen pohjautuvan suosituksen vatsaontelon sulusta arpityrien välttämiseksi. Sen mukaan arpityrän ehkäisyssä on oleellista sulkea laparotomiahaava käyttämällä hitaasti sulavaa monofilamenttilankaa vähintään neljä kertaa haavan mitan verran. Lisäksi jos potilaan arpityräriski on suuri, vatsaontelon sulun yhteydessä ulompaan lihaskalvoon tai lihaksen alle kiinnitettävät verkot saattavat vähentää myöhempiä arpityriä. Verkoista näyttävät eniten hyötyvän potilaat, joiden arpityräriski on erityisen suuri joko tietyntyyppisen leikkauksen tai perussairauden takia. Tutkimustieto tyriä ehkäisevien verkkojen hyödyistä ja turvallisuudesta on vielä niukkaa, mutta käyttökokemusten ja tutkimustulosten karttuessa verkkojen käyttö saattaa yleistyä.Abstract European Hernia Society (EHS) published 2015 a recommendation of abdominal wall closure based on a wide literature review. According to the recommendation, a correct wound closure technique with sufficient length of slowly absorbable monofilament suture is highly recommended for all patients regardless of later risk of abdominal wall hernias. Preventive meshes may decrease the incidence of abdominal wall hernias when used on patients at special risk for incisional hernia, either due to surgical procedure or individual risk factors. As the evidence on the effectiveness and safety of preventive meshes is growing, they are likely to be more commonly used

Case control study investigating the clinical utility of NPWT in the perineal region following abdominoperineal resection for rectal adenocarcinoma:a single center study

Abstract Background: Perineal wound complications are common after abdominoperineal resection (APR) for rectal adenocarcinoma. Delayed wound healing may postpone postoperative adjuvant therapy and, therefore, lead to a worse survival rate. Negative-pressure wound therapy (NPWT) has been suggested to improve healing, but research on this subject is limited. Methods: The aim of this study was to assess whether NPWT reduces surgical site infections (SSI) after APR for rectal adenocarcinoma when the closure is performed with a biological mesh and a local flap. A total of 21 consecutive patients had an NPWT device (Avelle, Convatec™) applied to the perineal wound. The study patients were compared to a historical cohort in a case–control setting in relation to age, body mass index, tumor stage, and length of neoadjuvant radiotherapy. The primary outcome was the surgical site infection rate. The secondary outcomes were the wound complication rate, the severity of wound complications measured by the Clavien–Dindo classification, length of hospital stay, and surgical revision rate. Results: The SSI rate was 33% (7/21) in the NPWT group and 48% (10/21) in the control group, p = 0.55. The overall wound complication rate was 62% (13/21) in NPWT patients and 67% (14/21) in the control group, p > 0.90. The length of hospital stay was 15 days in the NPWT group and 13 in the control group, p = 0.34. The wound severity according to the Clavien–Dindo classification was 3b in 29% (6/21) of the NPWT group and in 38% (8/21) of the control group. A surgical revision had to be performed in 29% (6/21) of the cases in the NPWT group and 38% (8/21) in the control group, p = 0.73. Conclusion: NPWT did not statistically decrease surgical site infections or reduce wound complication severity in perineal wounds after APR in this case–control study. The results may be explained by technical difficulties in applying NPWT in the perineum, especially in female patients. NPWT devices should be further developed to suit the perineal anatomy before their full effect can be assessed

Incidence of parastomal and incisional hernia following emergency surgery for Hinchey III-IV diverticulitis:a systematic review

Abstract Purpose: The aim of this systematic review was to evaluate the risk of parastomal (PSH) and incisional hernias (IH) after emergency surgery for Hinchey III–IV diverticulitis, with comparison between the Hartmann procedure and other surgical techniques. Methods: The Cochrane Library, Embase, PubMed (MEDLINE), Web of Science and Scopus databases were systematically searched. The primary endpoint was parastomal hernia incidence. The secondary endpoint was incisional hernia incidence. Results: Five studies (four randomized controlled trials and one retrospective cohort) with a total of 699 patients were eligible for inclusion. The PSH rate was 15%–46% for Hartmann procedure, 0%–85% for primary anastomosis, 4% for resection, and 2% for laparoscopic lavage. The IH rates were 5%–38% for Hartmann procedure, 5%–27% for primary anastomosis, 9%–12% for primary resection, and 3%–11% for laparoscopic lavage. Conclusions: Both the parastomal and incisional hernia incidences are poorly evaluated and reported, and varied greatly between the studies

Does ventral rectopexy improve pelvic floor function in the long term?

Abstract Background: Information is needed on long-term functional results, sequelas, and outcome predictors for laparoscopic ventral mesh rectopexy. Objective: The purpose of this study was to evaluate long-term function postventral rectopexy in patients with external rectal prolapse or internal rectal prolapse in a large cohort and to identify the possible effects of patient-related factors and operative technical details on patient-reported outcomes. Design: This was a retrospective review with a cross-sectional questionnaire study. Settings: Data were collated from prospectively collected registries in 2 university and 2 central hospitals in Finland. Patients: All 508 consecutive patients treated with ventral rectopexy for external rectal prolapse or symptomatic internal rectal prolapse in 2005 to 2013 were included. Interventions: A questionnaire concerning disease-related symptoms and effect on quality of life was used. Main outcome measures: Defecatory function measured by the Wexner score, the obstructive defecation score, and subjective symptom and quality-of-life evaluation using the visual analog scale were included. The effects of patient-related factors and operative technical details were assessed using multivariate analysis. Results: The questionnaire response rate was 70.7% (330/467 living patients) with a median follow-up time of 44 months. The mean Wexner scores were 7.0 (SD = 6.1) and 6.9 (SD = 5.6), and the mean obstructive defecation scores were 9.7 (SD = 7.6) and 12.3 (SD = 8.0) for patients presenting with external rectal prolapse and internal rectal prolapse. Subjective symptom relief was experienced by 76% and reported more often by patients with external rectal prolapse than with internal rectal prolapse (86% vs 68%; p < 0.001). Complications occurred in 11.4% of patients, and the recurrence rate for rectal prolapse was 7.1%. Limitations: This study was limited by its lack of preoperative functional data and suboptimal questionnaire response rate. Conclusions: Ventral mesh rectopexy effectively treats posterior pelvic floor dysfunction with a low complication rate and an acceptable recurrence rate. Patients with external rectal prolapse benefit more from the operation than those with symptomatic internal rectal prolapse. See Video Abstract at http://links.lww.com/DCR/A479

Laparoscopically guided transversus abdominis plane block versus local wound analgesia in laparoscopic surgery for peritoneal endometriosis:study protocol for a prospective randomized controlled double-blinded LTAP-trial

Abstract Background: Ultrasound-guided transversus abdominis plane block (TAP) performed by anesthesiologist has been shown to be an effective and safe analgesia method in abdominal surgery, reducing postoperative opioid consumption. Recently, there has been growing interest to insert TAP under laparoscopic vision (LTAP) by surgeon. LTAP has been used in laparoscopic gastrointestinal surgery, but studies on LTAP in gynecologic laparoscopic surgery are sparse and inconsistent. The purpose of this study is to compare the efficacy of LTAP and local wound analgesia in laparoscopic surgery due to suspected or diagnosed superficial peritoneal endometriosis. Methods: The LTAP-trial is a prospective randomized controlled double-blinded study comparing the efficacy and safety of LTAP with local wound analgesia in laparoscopic endometriosis surgery. Patients are randomized to receive LTAP with levobupivacaine and wound infiltration with placebo or wound infiltration with levobupivacaine and LTAP with placebo. The primary outcome is postoperative opioid consumption measured by patient-controlled analgesia (PCA) pump. Secondly, subjective postoperative pain up to 24 h postoperatively will be measured by Numeric Rating Scale (NRS). Additional outcome measures are factors related to recovery and length of stay in the hospital as well as a 6-month follow-up survey regarding pain (NRS) and endometriosis-related wellbeing (endometriosis-related health profile, EHP-30) after surgery. A total of 46 patients will be randomized in a proportion of 1:1. Discussion: Patients with peritoneal endometriosis are often prone to severe postoperative pain that may prohibit their enhanced recovery after laparoscopy. Thus, there is a need for effective postoperative pain management with minimal side-effects. This study focusing on laparoscopically inserted transversus abdominis plane block may provide new insight in dealing with postoperative pain after laparoscopic endometriosis surgery as well as after other gynecologic surgery

Robotic versus laparoscopic surgery for severe deep endometriosis:protocol for a randomised controlled trial (ROBEndo trial)

Abstract Introduction: Endometriosis is a common gynaecological disease affecting around 10% of fertile-aged women, causing severe pain symptoms. Deep endometriosis is defined as endometriotic implants that infiltrate the underlying organs more than 5 mm in depth. Surgery for deep endometriosis requires advanced multidisciplinary surgical technique, often in very difficult surgical conditions, with increased risks of complications. Robotic surgery offers a high-definition three-dimensional view and articulating instruments that may allow more precise dissection than conventional laparoscopy in the pelvic area. The superiority of robotic surgery has not, however, been provedin randomised controlled studies, and there is a lack of long-term outcome data. Advanced endometriosis surgery offers an excellent platform to study the feasibility and long-term outcomes of robotic surgery compared with conventional laparoscopy. Methods and analysis: ROBEndo is a prospective, randomised, controlled clinical trial in a single-centre setting. Patients with deep endometriosis verified by MRI needing surgery at Oulu University Hospital (Oulu, Finland) will be considered eligible. 70 patients will be allocated 1:1 to receive either robotic-assisted or conventional laparoscopic surgery in two strata: radical surgery (with the removal of the uterus and adnexae) and gynaecological organ-sparing surgery. The primary outcome will be the surgical outcome as regards to pain symptoms measured on numeric rating scale (NRS) questionnaires at 24 hours and 6, 12 and 24 months postoperatively. As secondary outcomes, intraoperative measures, enhanced recovery after surgery factors, complications, cost and long-term quality of life measured with Endometriosis Health Profile-30 (EHP-30), Female Sexual Function Index (FSFI) and 15-dimensional (15D) questionnaires will be compared. Ethics and dissemination: This study has been approved by the Northern Ostrobothnian Hospital District Ethical Committee at Oulu University Hospital (212/2021). Informed consent will be obtained during the preoperative check-up by the operating gynaecologist. The results will be published in peer-reviewed international journals. Trial registration number: NCT05179109

Quality-of-life and recurrence outcomes following laparoscopic elective sigmoid resection vs conservative treatment following diverticulitis:prespecified 2-year analysis of the LASER randomized clinical trial

Abstract Importance: Both elective sigmoid resection and conservative treatment are options for patients with recurrent, complicated, or persistent painful diverticulitis; understanding outcomes following each can help inform decision-making. Objective: To compare outcomes of elective sigmoid resection and conservative treatment for patients with recurrent, complicated, or persistent painful diverticulitis at 2-year follow-up. Design, Setting, and Participants: This multicenter parallel open-label individually randomized clinical trial comparing elective sigmoid resection to conservative treatment in patients with recurrent, complicated, or persistent painful diverticulitis was carried out in 5 Finnish hospitals between September 2014 and October 2018. Follow-up up to 2 years is reported. Of 85 patients randomized and included, 75 and 70 were available for QOL outcomes at 1 year and 2 years, respectively, and 79 and 78 were available for the recurrence outcome at 1 year and 2 years, respectively. The present analysis was conducted from September 2015 to June 2022. Interventions: Laparoscopic elective sigmoid resection vs conservative treatment (patient education and fiber supplementation). Main Outcomes and Measures: Prespecified secondary outcomes included Gastrointestinal Quality of Life Index (GIQLI) score, complications, and recurrences within 2 years. Results: Ninety patients (28 male [31%]; mean [SD] age, 54.11 [11.9] years and 62 female [69%]; mean [SD] age, 57.13 [7.6] years) were randomized either to elective sigmoid resection or conservative treatment. After exclusions, 41 patients in the surgery group and 44 in the conservative group were included in the intention-to-treat analyses. Eight patients (18%) in the conservative treatment group underwent sigmoid resection within 2 years. The mean GIQLI score at 1 year was 9.51 points higher in the surgery group compared to the conservative group (mean [SD], 118.54 [17.95] vs 109.03 [19.32]; 95% CI, 0.83-18.18; P = .03), while the mean GIQLI score at 2 years was similar between the groups. Within 2 years, 25 of 41 patients in the conservative group (61%) had recurrent diverticulitis compared to 4 of 37 patients in the surgery group (11%). Four of 41 patients in the surgery group (10%) and 2 of 44 in the conservative group (5%) had major postoperative complications within 2 years. In per-protocol analyses, the mean (SD) GIQLI score was higher in the surgery group compared to the conservative treatment group by 11.27 points at 12 months (119.42 [17.98] vs 108.15 [19.28]; 95% CI, 2.24-20.29; P = .02) and 10.43 points at 24 months (117.24 [15.51] vs 106.82 [18.94]; 95% CI, 1.52-19.33; P = .02). Conclusions and Relevance: In this randomized clinical trial, elective sigmoid resection was effective in preventing recurrent diverticulitis and improved quality of life over conservative treatment within 2 years.

Comparing laparoscopic elective sigmoid resection with conservative treatment in improving quality of life of patients with diverticulitis:the Laparoscopic Elective Sigmoid Resection Following Diverticulitis (LASER) randomized clinical trial

Abstract Importance: Diverticulitis has a tendency to recur and affect quality of life. Objective: To assess whether sigmoid resection is superior to conservative treatment in improving quality of life of patients with recurrent, complicated, or persistent painful diverticulitis. Design, Setting, and Participants: This open-label randomized clinical trial assessed for eligibility 128 patients with recurrent, complicated, or persistent painful diverticulitis in 6 Finnish hospitals from September 29, 2014, to October 10, 2018. Exclusion criteria included age younger than 18 years or older than 75 years; lack of (virtual) colonoscopy or sigmoidoscopy data within 2 years, or presence of cancer, contraindication to laparoscopy, or fistula. Outcomes were assessed using intention-to-treat analysis. A prespecified interim analysis was undertaken when 66 patients had been randomized and their 6-month follow-up was assessable. Data were analyzed from June 2018 to May 2020. Interventions: Laparoscopic sigmoid resection or conservative treatment. Main Outcomes and Measures: The primary outcome was difference in Gastrointestinal Quality of Life Index (GIQLI) score between randomization and 6 months. Results: Of 128 patients assessed for eligibility, 90 were randomized (28 male [31%]; mean [SD] age, 54.11 [11.9] years; 62 female [69%]; mean [SD] age, 57.13 [7.6] years). A total of 72 patients were included in analyses for the primary outcome (37 in the surgery group and 35 in the conservative treatment group), and 85 were included in analyses for clinical outcomes (41 in the surgery group and 44 in the conservative treatment group). The difference between GIQLI score at randomization and 6 months was a mean of 11.96 points higher in the surgery group than in the conservative treatment group (mean [SD] of 11.76 [15.89] points vs −0.2 [19.07] points; difference, 11.96; 95% CI, 3.72–20.19; P = .005). Four patients (10%) in the surgery group and no patients in the conservative treatment group experienced major complications (Clavien-Dindo grade III or higher). There were 2 patients (5%) in the surgery group and 12 patients (31%) in the conservative treatment group who had new episodes of diverticulitis within 6 months. Conclusions and Relevance: In this randomized clinical trial, elective laparoscopic sigmoid resection improved quality of life in patients with recurrent, complicated, or persistent painful diverticulitis but carried a 10% risk of major complications.

X-ray video defaecography is superior to magnetic resonance defaecography in the imaging of defaecation disorders

Abstract Aim: The aim of this work was to study the technical success and diagnostic capability of magnetic resonance defaecography (MRD) compared with video defaecography (VD). Method: Sixty four women with defaecation disorders underwent both MRD and x-ray VD over 1 year. The assessment by two radiologists in consensus was retrospective and blinded. The technical success of straining and evacuation was evaluated subjectively. The presence of enterocele, intussusception, rectocele and dyssynergic defaecation was analysed according to established criteria, with VD as the standard of reference. Results: It was found that 62/64 (96.9%) VD studies were technically fully diagnostic compared with 29/64 (45.3%) for MRD. The number of partially diagnostic studies was 1/64 (1.6%) for VD versus 21/64 (32.8%) for MRD, with 1/64 (1.6%) (VD) and 14/64 (21.9%) (MRD) being nondiagnostic. Thirty enteroceles were observed by VD compared with seven in MRD with moderate agreement (κ = 0.41). Altogether 53 intussusceptions were observed by VD compared with 27 by MRD with poor agreement (κ = −0.10 and κ = 0.02 in recto-rectal and recto-anal intussusception, respectively). Moderate agreement (κ = 0.47) was observed in diagnosing rectocele, with 47 cases by VD and 29 by MRD. Dyssynergic defaecation was observed in three patients by VD and in 11 patients by MRD, with slight agreement (κ = 0.14). Conclusions: The technical success and diagnostic capabilities of VD are better than those of MRD. VD remains the method of choice in the imaging of defaecation disorders
