Effects of intravenous single-bolus lidocaine infusion versus intravenous single-bolus magnesium sulfate infusion on postoperative pain, emotional status, and quality of life in patients undergoing spine fusion surgery: a randomized study.

BACKGROUND: We assessed the efficiency of intravenous adjuvants in decreasing opioid intake and pain scores after spine fusion surgery. METHODS: This study included 120 patients aged 18-60 listed for spine fusion surgery under general anesthesia. Patients were randomly assigned to four groups: Group (Lidocaine): received IV lidocaine 4 mg/kg in 50 mL volume over 30 min. Group (Magnesium): received IV magnesium sulfate 30mg/kg in 50 mL volume over 30 min. Group (combined Lidocaine and Magnesium): received IV lidocaine 4 mg/kg in 50 mL volume over 30 min.+IV magnesium sulfate 30mg/kg in 50 mL volume over 30 min. Group (Control): received IV saline 50 mL. The time to the first request analgesia, the postoperative pain score, total analgesic use, patient satisfaction, anxiety, depression, mental state, quality of life, and side effects were measured. RESULTS: The combined group had more extended time for the first analgesic request and fewer rescue analgesia doses than the other groups. NRS scores at rest or movement were statistically significantly lower in the lidocaine group and the combined group compared to the control group (P1, P3<0.05) at almost all times. This combination reduces anxiety and depression and improves overall health up to three months after a single infusion. The combined group had higher patient satisfaction. CONCLUSIONS: A synergistic effect of a combination of lidocaine and magnesium sulfate on perioperative pain was found. It reduces analgesic consumption, depression, and anxiety and improves overall health up to three months after a single infusion dose.

Resuming post living donor liver transplantation in the COVID-19 pandemic: real-life experience, single-center experience.

BACKGROUND: Solid organ transplantation (SOT) service has been disrupted during the current coronavirus disease 2019 (COVID-19) pandemic, which deferred the service in most centers worldwide. As the pandemic persists, there will be an urgency to identify the best and safest practices for resuming activities as areas re-open. Resuming activity is a difficult issue, in particular, the decision of reopening after a period of slowing down or complete cessation of activities. OBJECTIVES: To share our experience in resuming living donor liver transplantation (LDLT) in the context of the COVID-19 pandemic in the Liver Transplantation Unit of El-Manial Specialized Hospital, Cairo University, Egypt, and to review the obstacles that we have faced. MATERIAL AND METHODS: This study is a single-center study. We resumed LDLT by the 26th of August 2020 after a period of closure from the 1st of March 2020. We have taken a lot of steps in order to prevent COVID-19 transmission among transplant patients and healthcare workers (HCWs). RESULTS: In our study, we reported three LDLT recipients, once resuming the transplantation till now. All our recipients and donors tested negative for SARS-CoV-2 by nasopharyngeal RT-PCR a day before the transplantation. Unfortunately, one of them developed COVID-19 infection. We managed rapidly to isolate him in a single room, restricting one team of HCWs to deal with him with strict personal protective measures. Finally, the patient improved and was discharged in a good condition. The second patient ran a smooth course apart from FK neurotoxicity which improved with proper management. The third patient experienced a sharp rise in bilirubin and transaminases on day 14 that was attributed to drug toxicity vs. rejection and managed by discontinuing the offending drugs and pulse steroids. In addition, one of our head nurses tested positive for SARS-CoV-2 that was manageable with self-isolation. CONCLUSION: Careful patient, donor, personnel screening is mandatory. Adequate supply of personal protective equipments, effective infection control policies, and appropriate administrative modifications are needed for a safe return of LDLT practice.

Alpha lipoic acid with pulsed radiofrequency in treatment of chronic lumbosacral radicular pain: A prospective, randomized study.

BACKGROUND: The effect of adding alpha lipoic acid (ALA) to pulsed radiofrequency (PRF) for treatment of lumbar-sacral pain was evaluated. OBJECTIVE: to evaluate the effect of using ALA as an adjuvant therapy with PRF for treatment of chronic lumbosacral radicular pain caused by herniated disc. METHODS: One hundred twenty patients with lumbo-sacral radicular pain allocated into 2 groups. Group I: treated with PRF at 42°C for 120 seconds. Group II: treated as in group I, plus oral ALA 600 mg (Thiotacid 600 mg, EVA PHARMA, Egypt) three times per day (1800 mg/day) for 3 weeks then 600 mg once daily for 2 weeks. The lumbo-sacral radicular pain evaluated using the numerical rating pain score and Oswestry Disability Index. RESULTS: Success rate was significantly higher in group II at 3 and 6 months after intervention. The median values of the numerical rating pain score and the Oswestry Disability Index were significantly lower in group II with no significant difference in Epworth Sleepiness Scale. No major complications were reported in both groups. CONCLUSION: The current study supports the use of ALA with PRF on the dorsal root ganglion for treating lumbosacral radicular pain.

Early Effects of Laparoscopic Sleeve Gastrectomy and Laparoscopic One-Anastomosis Gastric Bypass on Portal Venous Flow: a Prospective Cohort Study.

BACKGROUND: Portal vein thrombosis (PVT) is an infrequent, yet potentially lethal, complication of bariatric surgery. The aim of this prospective, non-randomized, cohort study is to compare between laparoscopic sleeve gastrectomy (LSG) and laparoscopic one-anastomosis gastric bypass (LOAGB) in terms of their early postoperative effects on portal venous flow and patency. METHODS: Forty-nine morbidly obese patients were allocated to one of 2 groups (A or B). Group A patients underwent LSG, whereas group B patients underwent LOAGB. Portal venous Doppler ultrasound scanning was performed preoperatively and 2 weeks postoperatively in all cases, in order to assess the portal venous flow (PVF) in terms of flow direction and peak systolic velocity (PSV); as well as to assess the portal venous patency and exclude PVT. The mean change in PSV (ΔPSV) and the mean percentage change in PSV (%ΔPSV) were determined in both groups. RESULTS: In all cases (group A (n = 26); group B (n = 23)), the direction of PVF was "hepatopetal" both preoperatively and 2 weeks postoperatively. The mean ΔPSV and the mean %ΔPSV were higher in LSG patients "group A" (- 0.84 cm/s and 3.25% respectively) compared with LOAGB patients "group B"(- 0.06 cm/s and 0.27% respectively); P = 0.038 and 0.039 respectively. The mean change in PSV was in the negative direction in both groups, i.e., "deceleration." No cases of PVT were reported in the study. CONCLUSIONS: Laparoscopic sleeve gastrectomy is associated with greater reduction in portal venous peak systolic flow velocity in the early postoperative period, compared with laparoscopic one-anastomosis gastric bypass.

Management of early hepatic artery thrombosis following living-donor liver transplantation: feasibility, efficacy and potential risks of endovascular therapy in the first 48 hours post-transplant-a retrospective cohort study.

This retrospective cohort study aims to review our 18-year experience with early hepatic artery thrombosis (e-HAT) following living-donor liver transplantation (LDLT), as well as to assess the feasibility, efficacy and potential risks of endovascular management of e-HAT in the first 48 hours (hrs) post-LDLT. Medical records of 730 patients who underwent LDLT were retrospectively reviewed. In all cases who had developed e-HAT, treatment modalities employed and their outcomes were evaluated. Thirty-one patients developed e-HAT(4.2%). Definite technical success and 1-year survival rates of surgical revascularization[11/31 cases(35.5%)] were 72.7% & 72.7%, whereas those of endovascular therapy[27/31 cases(87.1%)] were 70.4% & 59.3%, respectively. Endovascular therapy was carried out in the first 48hrs post-transplant in 9/31 cases(29%) [definite technical success:88.9%, 1-year survival:55.6%]. Four procedure-related complications were reported in 3 of those 9 cases(33.3%). In conclusion, post-LDLT e-HAT can be treated by surgical revascularization or endovascular therapy, with comparable results. Endovascular management of e-HAT in the first 48hrs post-LDLT appears to be feasible and effective, but is associated with a relatively higher risk of procedure-related complications, compared to surgical revascularization. Hence, it can be reserved as a second-line therapeutic option in certain situations where surgical revascularization is considered futile, potentially too complex, or potentially more risky.

Fluoroscopic Guided Radiofrequency of Genicular Nerves for Pain Alleviation in Chronic Knee Osteoarthritis: A Single-Blind Randomized Controlled Trial.

BACKGROUND: Nowadays, pain and disability due to chronic knee arthritis is a very common problem in middle aged people. A lot of modalities for management are available, including conservative analgesics and up to surgical interventions. Radiofrequency ablation of genicular nerves is assumed to be an effective less invasive and safe pain alleviation modality. OBJECTIVES: To evaluate the efficacy of fluoroscopic guided radiofrequency neurotomy of the genicular nerves for alleviation of chronic pain and improvement of function in patients with knee osteoarthritis. STUDY DESIGN: A single-blind randomized controlled trial. SETTING: Pain management unit, and Rheumatology and Rehabilitation clinics of Assiut University hospitals, Assiut, Egypt. METHODS: This study involved 60 patients with chronic knee osteoarthritis. Radiofrequency neurotomy of the genicular nerves was done for 30 patients (Group A) while the other 30 patients (Group C) received conventional analgesics only. The outcome measures included visual analog scale (VAS), Western Ontario and McMaster Universities Index (WOMAC), and Likert scale for patient satisfaction in the 2nd week,3rd, and 6th months. RESULTS: There were significant differences regarding the VAS in the 2nd week, 3rd, and 6th months between the 2 groups, and a significant difference in total WOMAC index in the 6th month only. There were significant changes when comparing pretreatment values with the values during the whole follow-up period with regard to the VAS and total WOMAC index in both groups. LIMITATIONS: No diagnostic block was done prior to radiofrequency. We recommend the use of such a technique on a larger number of OA patients, with a longer follow-up period. CONCLUSION: RF can ameliorate pain and disability in chronic knee osteoarthritis in a safe and effective manner. KEY WORDS: Chronic pain, radiofrequency (RF), knee osteoarthritis.

Bile Gastritis Following Laparoscopic Single Anastomosis Gastric Bypass: Pilot Study to Assess Significance of Bilirubin Level in Gastric Aspirate.

INTRODUCTION: Laparoscopic single anastomosis gastric bypass (SAGB) is increasingly performed for morbidly obese patients. AIM OF WORK: This pilot study aims primarily at evaluating the incidence of bile gastritis after SAGB. The occurrence of reflux oesophagitis and reflux symptoms were also assessed. PATIENTS AND METHODS: This study included 20 patients having no reflux symptoms. All patients underwent a SAGB as a primary bariatric procedure by a single surgeon. Patients included consented to have an upper GI endoscopy done at 6 months postoperatively. Gastric aspirate was sent for bilirubin level assessment. Gastric and esophageal biopsies were submitted for histopathology and campylobacter-like organism (CLO) test. RESULTS: In our study, the rate of bile gastritis was 30%. In 18 patients, the level of bilirubin in gastric aspirate seems to be related to the degree of mucosal inflammation. The remaining two patients had microscopic moderate to severe gastritis with normal aspirate bilirubin level. Two patients with bilirubin level in aspirate more than 20 mg/dl had severe oesophagitis, gastritis with erosions, and metaplasia. Relationship between bilirubin level and histopathological findings of gastric biopsy examination was statistically significant with a P value of 0.001. CONCLUSION: The incidence of bile gastritis in this cohort is higher than reported in the literature, and this may be worrying. The correlation between endoscopic findings and patients' symptoms is poor. Bilirubin level and pH in aspirate might be useful tools to confirm alkaline reflux. Its level might help to choose candidates for revision surgery after SAGB. This needs further validation with larger sample size.

Biliary Complications in Recipients of Living-Donor Liver Transplant: A Single-Center Review of 120 Patients.

OBJECTIVES: Biliary complications are common after living-donor liver transplant. This retrospective study reviewed our experience with biliary complications in recipients of living-donor liver transplant. MATERIALS AND METHODS: Over our 9-year study period, 120 patients underwent living-donor liver transplant. Patients were divided into 2 groups, with group A having biliary complications and group B without biliary complications. Both groups were compared, and different treatment modalities for biliary complications were evaluated. RESULTS: Group A included 45 patients (37.5%), whereas group B included 75 patients (62.5%). Biliary complications included bile leak in 17 patients (14.2%), biliary stricture in 11 patients (9.2%), combined biliary stricture with bile leak in 15 patients (12.5%), and sphincter of Oddi dysfunction and cholangitis in 1 patient each (0.8%). Cold ischemia time was significantly longer in group A (P = .002). External biliary drainage was less frequently used in group A (P = .031). Technical success rates of endoscopic biliary drainage and percutaneous transhepatic biliary drainage were 68.3% and 41.7%. Survival rate following relaparotomy for biliary complications was 62.5%. CONCLUSIONS: Graft ischemia is an important risk factor for biliary complications. Bile leaks can predispose to anastomotic strictures. The use of external biliary drainage seems to reduce the incidence of biliary complications. Endoscopic and percutaneous trans-hepatic approaches can successfully treat more than two-thirds of biliary complications. Relaparotomy can improve survival outcomes and is usually reserved for patients with intractable biliary complications.

Effects of transcranial direct current stimulation on pain, mood and serum endorphin level in the treatment of fibromyalgia: A double blinded, randomized clinical trial.

BACKGROUND: Recent studies have shown that novel neuro-modulating techniques can have pain-relieving effects in the treatment of chronic pain. The aim of this work is to evaluate the effects of transcranial direct current stimulation (tDCS) in relieving fibromyalgia pain and its relation with beta-endorphin changes. MATERIAL AND METHODS: Forty eligible patients with primary fibromyalgia were randomized to receive real anodal tDCS or sham tDCS of the left motor cortex (M1) daily for 10 days. Each patient was evaluated using widespread pain index (WPI), symptom severity of fibromyalgia (SS), visual analogue scale (VAS), and determination of pain threshold as a primary outcome. Hamilton depression and anxiety scales (HAM-D and HAM-A) and estimation of serum beta-endorphin level pre and post-sessions were used as secondary outcome. All rating scales were conducted at the baseline, after the 5th, 10th session, 15 days and 1 month after the end of the sessions. RESULTS: Eighteen patients from each group completed the follow-up schedule with no significant difference between them regarding the duration of illness or the baseline scales. A significant TIME × GROUP interaction for each rating scale (WPI, SS, VAS, pain threshold, HAM-A, HAM-D) indicated that the effect of treatment differed in the two groups with higher improvement in the experimental scores of the patients in the real tDCS group (P = 0.001 for WPI, SS, VAS, pain threshold, and 0.002, 0.03 for HAM-A, HAM-D respectively). Negative correlations between changes in serum beta-endorphin level and the changes in different rating scales were found (P = 0.003, 0.003, 0.05, 0.002, 0002 for WPI, SS, VAS, HAM-A, and HAM-D respectively). CONCLUSION: Ten sessions of real tDCS over M1 can induce pain relief and mood improvement in patients with fibromyalgia, which were found to be related to changes in serum endorphin levels.

A portal pressure cut-off of 15 versus a cut-off of 20 for prevention of small-for-size syndrome in liver transplantation: A comparative study.

AIM: Portal hypertension has recently been implicated in the pathogenesis of small-for-size syndrome (SFSS) in adult-to-adult living-donor liver transplantation (A-LDLT). The aim of our study is to compare the portal venous pressure (PVP) cut-off values of 15 mmHg and 20 mmHg in terms of prevention of SFSS in A-LDLT. METHODS: Seventy-six patients underwent A-LDLT. A PVP <20 mmHg at the end of the operation was targeted using graft inflow modulation. Patients were divided into two groups: group A, final PVP <15 mmHg; and group B, final PVP 15-19 mmHg. Peak serum bilirubin and peak international normalized ratio in the first month after A-LDLT, as well as hepatic encephalopathy, SFSS, 90-day morbidity, and mortality were observed in both groups. RESULTS: Final PVP was well controlled below 20 mmHg in all patients (group A, n = 39; group B, n = 37). Six patients suffered SFSS in group B (16.2%) compared to one patient (2.6%) in group A (P = 0.04). Nine patients died in group B (24.3%), four of whom died of SFSS, compared to three patients in group A (7.7%) (P = 0.047). CONCLUSION: A PVP cut-off of 15 mmHg seems to be a more appropriate target level than a cut-off of 20 mmHg for prevention of postoperative SFSS in A-LDLT.

Role of Doppler Ultrasonography in Defining Normal and Abnormal Graft Hemodynamics After Living-Donor Liver Transplant.

OBJECTIVES: Our aim was to investigate the early changes that occur after graft perfusion in living-donor liver transplant by Doppler ultrasonography. MATERIALS AND METHODS: We prospectively evaluated liver grafts of 30 patients who underwent living-donor liver transplant during an 18-month period and who were followed for 1 year postoperatively. The hepatic artery peak systolic velocity, resistivity index, portal vein velocity, portal vein anastomotic velocity ratio, and hepatic vein pattern were compared after excluding patients who developed vascular complications and acute rejection episodes. RESULTS: We observed intraoperative increases in the mean hepatic artery peak systolic velocity (96.3 ± 65 cm/s), the resistivity index (0.78 ± 0.091), and the portal vein velocity (99.6 ± 48 cm/s), which started to normalize after 2 weeks. In comparing the mean portal vein velocity, portal vein anastomotic velocity ratio, hepatic artery peak systolic velocity, and resistivity index after excluding 5 patients who developed vascular complications, we observed overall significance levels of P < .001, P = .039, P < .001, and P = .040. After we excluded 9 patients who developed acute rejection, our comparison of the portal vein velocity, hepatic artery peak systolic velocity, and resistivity index showed overall significance (P < .001, P < .001, and P = .043). CONCLUSIONS: Early and transient increases in portal vein velocity, anastomotic velocity ratio, hepatic artery peak systolic velocity, and resistivity index are common after living-donor liver transplant, with significant declines in the first 2 weeks posttransplant.

Pulsed Compared to Thermal Radiofrequency to the Medial Calcaneal Nerve for Management of Chronic Refractory Plantar Fasciitis: A Prospective Comparative Study.

BACKGROUND: Radiofrequency (RF) treatment is a minimally invasive procedure that has been used for more than 3 decades in treating various chronic pain syndromes. Conventional (continuous) RF treatment occasionally results in worsening or even initiating a new type of pain. The use of pulsed radiofrequency (PRF), which has a non- or minimally neurodestructive neuromodulatory effect, serves as an alternative to conventional RF therapy in many medical situations. OBJECTIVES: To evaluate the effect of applying PRF for 6 minutes vs. thermal radiofrequency (TRF) for 90 seconds to the medial calcaneal nerve for treatment of chronic refractory plantar fasciitis pain. STUDY DESIGN: Prospective comparative study. SETTING: Pain, Orthopedic, and Rheumatology and Rehabilitation Clinics of Assiut University Hospital. METHODS: Twenty patients with refractory chronic bilateral plantar fasciitis received PRF to the medial calcaneal nerve for 6 minutes for one heel and TRF to the same nerve on the other heel (as their own control) for 90 seconds. Numerical verbal rating scale (NVRS) at waking up from bed and after prolonged walking, and satisfaction score were used for assessment of studied patients at one, 3, 6, 12, and 24 weeks from the intervention. RESULTS: All studied patients showed significant improvement in their pain scale after the intervention that lasted for 24 weeks; however, the PRF heels had significantly better pain scale and satisfaction scores at the first and third weeks assessments when compared to the TRF heels. Effective analgesia was achieved after one week or less after PRF compared to 3 weeks for the TRF (P < 0.001). LIMITATIONS: No randomization. CONCLUSIONS: PRF to the medial calcaneal nerve is a safe and effective method for treatment of chronic plantar fasciitis pain. The onset of effective analgesia can be achieved more rapidly with PRF compared to TRF on the same nerve. Further randomized trials are needed to confirm the therapeutic effect and optimizing the dose of RF needed.Key words: Pulsed radiofrequency, thermal radiofrequency, medial calcaneal nerve, plantar fasciitis, plantar aponeurosis, visual analogue scale.

Post Dural Puncture Headache in Fibromyalgia after Cesarean Section: A Comparative Cohort Study.

BACKGROUND: Patients of chronic pain syndromes like fibromyalgia (FMS) when subjected to spinal anesthesia are theoretically more liable to post dural puncture headache (PDPH) as they have enhanced central nervous system sensitization and decreased descending inhibition. OBJECTIVE: The current study aims to verify the incidence and chronicity of PDPH in FMS patients. STUDY DESIGN: Case control study. METHODS: In a comparative control study, 70 fibromyalgia patients were scheduled for an elective cesarean delivery fibromyalgia group or Group 1. Group 2 included 70 women scheduled for elective cesarean delivery who had no history of chronic pain and is used as a control group. Both groups were compared regarding the incidence of development of PDPH in the first postoperative 48 hours and the persistence of PDPH for 7 days or more. SETTINGS: Women's Health Hospital, Assiut University, antenatal Clinic. RESULTS: The fibromyalgia group reported more PDPH (18 patients, 25.7%) as compared to the control group (10 patients, 14.3%), P < 0.01. PDPH persisted for 7 or more days in 8 patients in the fibromyalgia group (11.4%) while, it persisted in 2.86% of the control patients. PDPH continued for more than 3 months in 2 patients in the fibromyalgia group (2.86%). LIMITATIONS: Difficulty in calculating the dose of analgesics as patients with fibromyalgia may use other analgesics due to musculoskeletal pain. CONCLUSION: Dural puncture increases the incidence of PDPH in fibromyalgia patients in comparison with normal controls without increasing other postoperative side effects.

Early Weight Recidivism Following Laparoscopic Sleeve Gastrectomy: A Prospective Observational Study.

BACKGROUND: Although weight loss following laparoscopic sleeve gastrectomy (LSG) can be substantial, weight recidivism is still a major concern. The aim of our work is to study early weight recidivism following LSG and to evaluate the role of gastric computed tomography volumetry (GCTV) in the assessment of patients experiencing early weight regain. METHODS: One-hundred and one morbidly obese patients undergoing LSG were prospectively studied. Patients were followed up for 2 years. Those who presented with weight recidivism were counseled for dietary habits and assessed for the amount of weight regain. Patients who regained weight were scheduled for GCTV. RESULTS: Twelve patients were excluded from the study. Weight recidivism was reported in 9/89 patients (10.1 %) [weight loss failure (n = 1), weight regain (n = 8)] and was almost always first recognized 1½-2 years after LSG. The amount of weight regain showed negative correlations with preoperative body weight and body mass index (r = -0.643, P = 0.086 and r = -0.690, P = 0.058; respectively) and positive correlations with the distance between the pylorus and the beginning of the staple line (r = 0.869, P = 0.005), as well as with the residual gastric volume (RGV) on GCTV 2 years after LSG (r = 0.786, P = 0.021). CONCLUSIONS: In the small group of patients who regained weight, a longer distance between the pylorus and the beginning of the staple line, as well as a higher RGV on GCTV 2 years after LSG, were both associated with increased weight regain. Gastric computed tomography volumetry with RGV measurement holds promise as a useful research tool after LSG.

Operative management of biliary peritonitis complicating blunt hepatic trauma using partial hepatectomy and trans-hepatic biliary stenting.

INTRODUCTION: Biliary peritonitis complicating blunt hepatic trauma is a rare but potentially lethal condition. PRESENTATION OF CASE: A 17-year old male patient who sustained a complex grade IV blunt hepatic trauma presented with severe haemorrhagic shock after an initial laparotomy in another hospital. An urgent exploratory laparotomy revealed a shattered posterior section of the right liver and suture haemostasis of the lacerated liver surface was performed. Postoperatively, the patient developed generalized biliary peritonitis and another laparotomy with peritoneal lavage and drainage was performed on postoperative day 12. However, ongoing manifestations of peritonitis and sepsis necessitated a third laparotomy 6 days later. This revealed ongoing biliary peritonitis due to major intra-hepatic bile duct injury. A partial hepatectomy with intra-operative trans-hepatic biliary stenting was undertaken. Postoperative recovery was uneventful and the biliary fistula healed completely by the end of the second postoperative week. DISCUSSION: Major intra-hepatic bile duct injury following blunt hepatic trauma is an extremely rare cause of biliary peritonitis. CONCLUSION: The combination of partial hepatectomy with intra-operative trans-hepatic biliary stenting proved to be a safe and effective method for treatment of biliary peritonitis due to major intra-hepatic bile duct injury following blunt hepatic trauma when non-operative management fails.

Parietal peritoneal closure and persistent postcesarean pain.

OBJECTIVE: To assess the incidence of persistent pain after cesarean delivery. METHODS: A total of 340 pregnant women with no history of abdominal surgery were randomized to undergo or not undergo parietal peritoneal closure following elective cesarean delivery. Pain scores were recorded on the 1st and 15th postoperative day and the women were followed up every 2 weeks up to 8 months after surgery. RESULTS: Overall and epigastric abdominal pain were more frequent in the closure than in the nonclosure group. Pain scores on the 1st and 15th days and after 8 months were higher in the closure group, in which the incidence of persistent postcesarean pain was 17.8% after 8 months. CONCLUSION: Parietal peritoneal closure after cesarean delivery is associated with a higher incidence of early and persistent postoperative pain. A high pain score on the 1st day is a predictor of persistent pain.
