Risk Factors of Acute Pain in Elderly Patients After Laparoscopic Radical Resection of Colorectal Cancer.

OBJECTIVE: To investigate the risk factors of acute pain after laparoscopic radical resection of colorectal cancer (CRC) in elderly patients. METHODS: Totally, 143 elderly patients (≥ 60 y old) who received laparoscopic radical resection of CRC in the People's Hospital of Xinjiang Uygur Autonomous Region from March 2021 to August 2022 were retrospectively analyzed. The patients were divided into 2 groups according to visual analog scale (VAS) scores 24 h after surgery: mild pain group (VAS score ≤ 3, n=108) and moderate to severe pain group (VAS score >3, n=35). The data of the patients, including sex, age, height, body mass, intraoperative blood loss, intraoperative urine volume, intraoperative opioid dosage, operation duration, preoperative Hospital Anxiety and Depression Scale (HADS) scores, preoperative Mini-Mental State Examination scores, VAS scores, postoperative nausea and vomiting scores were recorded. Multivariate logistic regression analysis was used to screen the risk factors of postoperative acute pain in elderly patients undergoing laparoscopic radical resection of CRC. RESULTS: The preoperative HADS score of the moderate to severe pain group was significantly increased compared with that of the mild pain group (10.8±2.4 vs. 6.2±1.9), as well as the operation duration (226.4±18.3 vs. 186.1±12.7), the intraoperative dosage of remifentanil (3.7±0.2 vs. 3.2±0.4), the preoperative VAS score [4(2, 7) vs. 2 (0, 4)] and postoperative VAS score [5 (4, 6) vs. 3 (2, 3)] ( P <0.05). Multivariate logistic regression analysis showed that high preoperative HADS score, long operation duration, and high preoperative VAS score ( P <0.05) were independent risk factors for acute pain after laparoscopic radical resection of CRC in elderly patients. CONCLUSION: Preoperative anxiety and depression, preoperative pain, and long operation duration are risk factors for acute pain in elderly patients after laparoscopic radical resection of CRC.

Comparison of Acute Pain Syndrome after Surgical Interventions in the Nasal Cavity and Rhinoplasty.

Comparison of acute pain syndrome after septoplasty, rhinoplasty, and rhinoseptoplasty was carried out. It is shown that the intensity of acute pain is higher in patients after rhinoseptoplasty in the first 3-6 h after surgery.

Postoperative compression in preventing early complications after groin hernia repair.

PURPOSE: We conducted this study to investigate the efficacy, safety, and clinical value of postoperative compression in preventing seroma formation, relieving acute pain, and improving QoL after groin hernia repair. METHODS: This multi-center, prospective, observational real-world study was conducted from March 1, 2022, to August 31, 2022. The study was completed in 53 hospitals in 25 provinces in China. A total of 497 patients who underwent groin hernia repair were enrolled. All patients used a compression device to compress the operative region after surgery. The primary outcome was seroma incidence 1 month after surgery. Secondary outcomes included postoperative acute pain and QoL. RESULTS: A total of 497 patients [median (IQR) age 55 (41-67) years, 456 (91.8%) male] were enrolled, of whom 454 underwent laparoscopic groin hernia repair and 43 open hernia repair. The follow-up rate was 98.4% 1 month after surgery. Seroma incidence was 7.2% (35 of 489 patients) overall, lower than reported by previous research. No significant differences were found between the two groups (P > 0.05). VAS scores after compression were significantly lower than before compression overall and in both groups (P < 0.001). The laparoscopic group showed a high level of QoL compared with the open group, but there was no significant difference between the two groups (P > 0.05). CCS score correlated positively with VAS score. CONCLUSION: Postoperative compression, to a certain extent, can reduce seroma incidence, relieve postoperative acute pain, and improve QoL after groin hernia repair. Further large-scale randomized controlled studies are warranted to determine long-term outcomes.

Transabdominal preperitoneal versus hybrid procedures for treating irreducible inguinal hernias: A retrospective controlled study.

BACKGROUND: Inguinal hernia is a common condition; however, irreducible inguinal hernias are rare. In this retrospective study, two laparoscopic procedures for irreducible inguinal hernia were compared. MATERIALS AND METHODS: The study cohort comprised 88 patients who had undergone laparoscopic repair of primary irreducible inguinal hernias between 1 June 2011 and 31 December 2019. The patients were retrospectively divided into Hybrid (Group H) and Standard Transabdominal Preperitoneal (TAPP) Groups (Group S). Patient characteristics, hernia details, and intraoperative and postoperative complications were compared between study groups. RESULTS: There were no significant differences between the two groups in baseline characteristics, including age, sex, body mass index, hernia type, operation time, hospital stay, cost, and duration of follow-up. No recurrence or surgical site infection occurred in either group. There were no significant differences between the two groups in incidence of spermatic vessel injury (0% vs. 2.04%, P = 0.370), vas deferens injury (0% vs. 6.12%, P = 0.116), epigastric vessels injury (0% vs. 4.08%, P = 0.202), scrotal hematoma (7.69% vs. 2.04%, P = 0.206), dysuria (5.13% vs. 8.16%, P = 0.575), fever (17.95% vs. 16.32%, P = 0.841), seroma (25.64% vs. 32.65%, P = 0.474), chronic pain (0% vs. 2.04%, P = 0.370), sensation of a foreign body (2.56% vs. 2.04%, P = 0.870), or pain on ejaculation (0% vs. 2.04%, P = 0.370). The incidence of acute pain was higher in Group H than in Group S (43.59% vs. 8.16%, P = 0.000). CONCLUSION: The hybrid TAPP procedure is a safe and feasible means of treating irreducible inguinal hernias. Though it is associated with a higher incidence of postoperative acute pain than the standard TAPP procedure, it may have advantages in avoiding injuries to the vas deferens and spermatic vessels.

Predictive factors of postoperative acute pain in laparoscopic inguinal hernia repair in men: A single-centre retrospective study in Japan.

INTRODUCTION: Laparoscopic inguinal hernia repair has significantly reduced the incidence of postoperative acute and chronic pain compared to open repair, but it remains problematic. This study's purpose was to retrospectively identify predictive factors of acute pain after laparoscopic inguinal hernia repair. METHODS: We reviewed the medical records of 193 patients. After excluding atypical cases and female patients, 156 patients were analysed. Factors affecting rescue analgesic requirements were investigated via multivariable logistic regression analysis. Independent variables included age, body mass index, analgesics used during surgery and surgical factors (unilateral/bilateral, primary/recurrent). The degree of postoperative pain and the hospital stay duration after surgery were also investigated. RESULTS: Of the 156 patients, 40 (25.6%) required rescue analgesics. Patients under 60 years of age were about seven times more likely to need rescue analgesics than patients over 80 years of age. Primary surgery patients were about 5.5 times more likely to need rescue analgesics than recurrent surgery patients. The maximum verbal rating scale score was less than 3 in 89% of patients. All patients were discharged by two days postoperatively. CONCLUSION: Laparoscopic inguinal hernia repair results in less postoperative acute pain. However, analgesia management should be considered prudently for younger patients and primary surgery patients.

Resveratrol increases tear production and ocular pain after corneal abrasion in male, but not female, rats using a photorefractive keratectomy model.

Photorefractive keratectomy (PRK) is an alternative to LASIK and can cause intense acute pain that is often not relieved by standard treatments. To assess potential therapeutics for this type of acute pain, appropriate preclinical models are needed. We describe a preclinical corneal abrasion rat model that simulates the initial stages of PRK surgery and demonstrates similar pain and tear dysfunction as seen clinically. We used both behavioral and homeostatic assays to determine the therapeutic potential of resveratrol on pain and tear production. Studies were conducted in male and female Sprague-Dawley rats. Heptanol was applied to one eye and the superficial corneal epithelium was removed, mimicking the abrasion used in PRK. Spontaneous pain was assessed with orbital tightening (OT) scores for 7 days. Topical resveratrol increased OT scores sex-specifically in abraded males, but not females, at 72 h and 1 week after abrasion. Resveratrol increased tear production in abraded males, with no effect in abraded females. There was no correlation between OT score at 1 week and tear production measurements, demonstrating no relationship between spontaneous ocular pain and tear dysfunction in this model. These findings demonstrate the usefulness of our corneal abrasion preclinical PRK model for the assessment of ocular pain therapeutics and indicate that topical resveratrol may not be useful for managing PRK-induced pain.

Robotic-Assisted Esophagectomy Leads to Significant Reduction in Postoperative Acute Pain: A Retrospective Clinical Trial.

BACKGROUND: Robot-assisted minimally invasive esophagectomy (RAMIE) shows promising results regarding postoperative complications in patients with esophageal cancer. To date, no data are available regarding postoperative analgesic consumption. The aim of this work is to evaluate analgesic consumption after esophagectomy. METHODS: A total of 274 Ivor Lewis esophageal resections performed sequentially from January 2012 to December 2020 were evaluated. RAMIE cases (n = 51) were compared with the hybrid technique (laparoscopic abdominal phase followed by open thoracotomy, n = 59) and open abdominothoracic esophagectomy (OTE) (n = 164). Data were collected retrospectively. The primary endpoint was the overall postoperative morphine consumption, which represents a reliable indirect measurement of pain. Pain levels recorded on the first, third, and fifth postoperative days were assessed as secondary endpoints. RESULTS: A total of 274 patients were included. The postoperative opioid consumption rate for patients who underwent RAMIE (quartiles: 0.14, 0.23, 0.36 mg morphine milligram equivalents (MME)/kg body weight (bw)/day) was significantly lower than in the open group (0.19, 0.33, 0.58 mg MME/kg bw/day, p = 0.016). The overall postoperative opioid consumption for patients who underwent RAMIE was significantly lower (2.45, 3.63, 7.20 mg MME/kg bw/day; morphine milligram equivalents per kilogram body weight) compared with the open (4.85, 8.59, 14.63 MME/kg bw/day, p < 0.0001) and hybrid (4.13, 6.84, 11.36 MME/kg bw/day, p = 0.008) groups. Patients who underwent RAMIE reported lower pain scores compared with the open group on the fifth postoperative day, both at rest (p = 0.004) and while performing activities (p < 0.001). CONCLUSIONS: This study shows that patients who underwent RAMIE experienced similar postoperative pain while requiring significantly lower amounts of opioids compared with patients who underwent open and hybrid surgery. Further studies are required to verify the results.

Predictive Factors for Acute Postoperative Pain After Open Radical Gastrectomy for Gastric Cancer.

Background: Pain has become an important factor in evaluating patients' quality of life and clinical treatment. For gastric cancer (GC) patients, open radical gastrectomy (OG) causes significant trauma to the body, increases patients' pain after operation, and delays early recovery. The aim of this study was to investigate the predictive factors of acute pain after OG within postoperative 72 h. Methods: From March 2020 to September 2021, 307 patients who underwent OG were included in the study in Nanjing Drum Tower Hospital. The predictors included demographic predictors, pathological data, surgical predictors, and intraoperative predictors. The pain scores at 12, 24, 48, and 72 h after operation were evaluated by numeric rating scale (NRS). The predictors of acute pain were determined by univariate and multivariate analysis. Results: The average pain score (NRS) of patients showed a downward trend over time within 72 h after OG. Multivariate analysis indicated that total gastrectomy (OR 1.823, 95% CI 1.094-3.040, P < 0.05), AJCC TNM stage (II) (OR.232, 95% CI 0.062-0.872, P < 0.05), AJCC TNM stage(III) (OR.185, 95% CI 0.049-0.698, P < 0.05), BMI (kg/m2) (OR 1.75, 95% CI 1.029-2.976, P < 0.05), distant metastasis (OR 3.054, 95% CI 1.019-9.155, P < 0.05), intraoperative transfusion (OR 2.246, 95% CI 1.267-3.982, P < 0.01) were significant predictive factors for acute pain after OG. Conclusion: Reasonable postoperative acute pain control was the prerequisite for accelerating the postoperative rehabilitation of patients. In order to reduce the occurrence of excessive or insufficient analgesia, it was necessary for patients who underwent OG to formulate appropriate analgesics according to risk factors.

Preoperative Predictors for Acute Pain After Photorefractive Keratectomy.

PURPOSE: The aim of this study was to identify preoperative predictors for the occurrence of early severe postoperative pain in patients undergoing photorefractive keratectomy (PRK). The implementation of preoperative screening methods may facilitate more specific or aggressive pain therapies specifically targeted to individuals at a high risk of experiencing severe postoperative pain. METHODS: This was exploratory research that included patients who underwent PRK. Before PRK, patients were administered a sociodemographic questionnaire, the Pain Catastrophizing Scale, and the State-Trait Anxiety Inventory and underwent corneal sensitivity and conditioned pain modulation (CPM) tests. Post-PRK pain was assessed using a pain intensity visual analog scale (VAS), and the short-form McGill Pain Questionnaire (SF-MPQ) was completed 21 days before PRK and 1, 24, 48, and 72 hours after PRK. Spearman correlations were calculated for pain scores and preoperative predictors. RESULTS: This research included 34 eyes of 34 patients. Preoperative corneal sensitivity was positively correlated with post-PRK pain scores as assessed by VAS and SF-MPQ (rho = 0.39 and rho = 0.41, respectively, P < 0.05). No correlations were found between Pain Catastrophizing Scale, State-Trait Anxiety Inventory, and CPM scores and post-PRK pain scores ( P > 0.05). CONCLUSIONS: Abnormal presurgical corneal sensitivity was a protective marker for severe pain after PRK, while scores as assessed by VAS and SF-MPQ and CPM were not related to postoperative pain.

Short-Term Effects of Isometric Quadriceps Muscle Exercise with Auditory and Visual Feedback on Pain, Physical Function, and Performance after Total Knee Arthroplasty: A Randomized Controlled Trial.

Severe acute pain after total knee arthroplasty (TKA) may cause delay in muscle strength and functional recovery, and it is a risk factor for chronic postoperative pain. Although pharmacological approaches are the typical firstline to treat acute pain; recently, nonpharmacological approaches such as exercise have been increasingly applied. The purpose of this investigation was to evaluate the effects of a rehabilitation program involving isometric quadriceps exercise with auditory and visual feedback to improve the short-term outcome after TKA. Sixty-two patients, planning a primary unilateral TKA, were randomly assigned to either an intervention group (n = 31) involving isometric quadriceps exercise with auditory and visual feedback in usual rehabilitation after TKA or a control group (n = 31) involving a standardized program for TKA. Patients in the intervention group performed the isometric quadriceps muscle exercise using the Quadriceps Training Machine from 2 to 14 days after TKA instead of the traditional quadriceps sets. Pain intensity, isometric knee extension strength, range of motion, timed up and go test (TUG), 10-m gait speed, 6-minute walking distance, the Western Ontario and McMaster University Osteoarthritis index (WOMAC), the hospital anxiety and depression scale, and the pain catastrophizing scale were assessed before TKA (baseline) and 1 to 3 weeks after TKA. Pain intensity significantly decreased in the intervention group than in the control group at 1 (p = 0.005), 2 (p = 0.002), and 3 (p = 0.010) weeks after TKA. Greater improvements in TUG (p = 0.036), 10-m gait speed (p = 0.047), WOMAC total score (p = 0.017), pain (p = 0.010), and function (p = 0.028) 3 weeks after TKA were observed in the intervention group. These results suggest that isometric quadriceps exercises with auditory and visual feedback provided early knee pain relief, possibly leading to better improvements in physical performance, and patient's perception of physical function in the early stages of postoperative TKA. Further studies should investigate whether this short-term effect is sustainable.

The Effect of Early Limited Activity after Bipedicular Percutaneous Vertebroplasty to Treat Acute Painful Osteoporotic Vertebral Compression Fractures.

BACKGROUND: Although percutaneous vertebroplasty (PVP) can effectively relieve the pain for patients with acute osteoporotic vertebral compression fractures (OVCFs), many patients still complain of mild back pain in the early postoperative period. OBJECTIVES: The aim of this study was to assess the effect of early limited activity (LA) on prognosis after bipedicular small-cement-volume (i.e., PVP) to treat single-segment acute OVCFs. STUDY DESIGN: A prospective study and retrospective observations were performed on 125 patients with a minimum of 1 year of follow-up. SETTING: A university hospital orthopedics and pathology departments. METHODS: All patients were allocated into an LA group (n = 64) and an unlimited activity group (ULA group, n = 61). Patients in the LA group were suggested to keep time of off-bed activity < 4 hours per day in the first 3 weeks postoperatively. Patients in the ULA group did not limit activity. The demographic, clinical, and radiologic outcomes were assessed, such as pain intensity Numeric Rating Scale (NRS-11) and vertebral height ratio (i.e., fractured vertebral height/adjacent nonfractured vertebral height). Based on outcomes following surgery, all patients were classified as responders (NRS-11 score 1-day postoperation < 50% of preoperative NRS-11 score) or low responders (NRS-11 score 1-day postoperation >= 50% of preoperative NRS-11 score). RESULTS: The demographic results and complications were similar. In the LA group, NRS-11 scores at 1 and 3 months postoperation respectively were 2.23 ± 0.42 and 1.46 ± 0.40, and corresponding scores respectively were 2.85 ± 0.80 and 1.73 ± 0.77 in the ULA group, and there was a difference in the 2 groups in both time points (P < 0.05). At 12 months postoperation, anterior and middle vertebral height ratio respectively were 78.42% ± 3.52% and 82.37% ± 3.49% in the LA group, which were higher than 76.87% ± 3.68% and 81.10% ± 3.31% in the ULA group (P < 0.05). Thirty-two cases were low responders. Among those, NRS-11 scores at 1 and 3 months postoperation respectively were 2.29 ± 0.45 and 1.53 ± 0.46 in the LA group, which were lower than 3.67 ± 0.80 and 2.56 ± 0.79 in the ULA group (P < 0.05), and at 12 months postoperation, anterior vertebral height ratio was 79.81% ± 3.25% in the LA group and 75.60% ± 3.50% in the ULA group (P < 0.05). LIMITATIONS: First, some patients lacked the results of bone mineral density during follow-up; second, the limited time in our study was chosen from our previous working experience, which may lack an objective basis; third, NRS-11 is solely used as an indicator of clinical outcomes in our study; finally, our next studies can increase the sample size to improve the clinically difference. CONCLUSIONS: LA in the early period after PVP can help patients achieve more pain relief postoperatively and maintain better vertebral shape, especially for low responders. KEY WORDS: Osteoporotic vertebral compression fractures, percutaneous vertebroplasty, Numeric Rating Scale, vertebral height, responders, low responders, limited activity, complications.

[A woman with acute flank pain]. / Een vrouw met acuut ontstane flankpijn.

A 55-year-old woman presented at the Emergency Department with flank pain. She was pale, hemodynamically unstable, and had a palpable mass in her right flank. CTA of the abdomen revealed a bleeding from an angiomyolipoma of the right kidney, which was successfully treated by selective coiling of the supplying renal artery.

Severe acute pain and persistent post-surgical pain in orthopaedic trauma patients: a cohort study.

BACKGROUND: We conducted a cohort study of adult patients presenting for orthopaedic trauma surgery at a statewide trauma centre, with the aims of determining (i) the incidence and risk factors for severe acute pain in the PACU, and (ii) the incidence and risk factors for persistent post-surgical pain at 3 months. METHODS: Data were collected before operation, in the PACU, 72 h after surgery and 3 months after surgery, and included numerical rating scale (NRS) scores for pain, and modified Brief Pain Inventory-Short Form, Kessler Psychological Distress Scale, World Health Organization Disability Assessment Schedule, and Pain Catastrophizing Scale scores. RESULTS: Severe acute pain in the PACU was reported by 171 (56%; 95% confidence interval [CI]: 51%, 62%) of the 303 included patients. Female sex (odds ratio [OR]: 1.86; 95% CI: 1.06, 3.26) and prior post-injury surgery (OR: 2.21; 95% CI: 1.11, 4.41) remained associated with severe acute pain after multivariable adjustment. Persistent post-surgical pain at 3 months was reported by 149 (65%; 95% CI: 59%, 71%) of the 229 included patients. The preoperative NRS score (OR: 1.17; 95% CI: 1.03, 1.32) remained associated with persistent pain after multivariable adjustment. CONCLUSIONS: We identified three easy-to-measure risk factors: female sex, prior post-injury surgery for severe acute pain, and preoperative NRS scores for persistent pain. Further research is required to identify pain management strategies and psychosocial interventions to reduce the burden of pain, disability, and distress in these patients.

Comparison of Emergent and Elective Surgeries of Endometriomas: Is Adnexal Torsion a Concern?

BACKGROUND: When a woman with an endometrioma presents with acute abdominal pain, it is unclear whether ovarian torsion should be suspected. OBJECTIVES: To compare patient characteristics, imaging results, and surgical management of endometriomas in elective versus emergent surgeries. METHODS: This retrospective cohort study included women treated at our institution during the period 1990-2015 who presented with histologically verified endometrioma and who underwent either planned surgery or emergent surgery due to suspected adnexal torsion. RESULTS: Of 225 surgeries performed, 174 were elective and 51 emergent. Patients in the emergent group were significantly younger (33.9 ± 11.1 vs. 39.01 ± 10.9 years, P = 0.004). Abdominal pain was the main complaint of all the emergent surgery patients and the leading complaint in 21% of the elective surgery patients (P < 0.001), with right-sided predominance in both groups. Sonographic parameters were similar in both groups. Bilateral ovarian cysts were noted in 11.7% and 11.0% of emergent and elective patients, respectively (P = 0.87). Laboratory evaluation was notable for a higher white blood cell count and CA125 levels among emergent patients. All patients in the emergent group and 93% of patients in the elective group were managed laparoscopically. No cases of torsion were noted. The rate of intra-pelvic adhesions was similar in both groups (56.8% vs. 66.6%, P = 0.19). CONCLUSIONS: Endometrioma may present with acute abdominal pain. However, adnexal torsion in these patients is rare. These cases can be managed using a minimally invasive approach, assuming an optimal surgical setting.

Emergency presentations of acute biliary pain: changing patterns of management in a tertiary institute.

BACKGROUND: Acute biliary pain is the most common presentation of gallstone disease. Untreated patients risk recurrent pain, cholecystitis, obstructive jaundice, pancreatitis and multiple hospital presentations. We examine the outcome of implementing a policy to offer laparoscopic cholecystectomy on index presentation to patients with biliary colic in a tertiary hospital in Australia. METHODS: This is a retrospective cohort study of adult patients presenting to the emergency department (ED) with biliary pain during three 12-month periods. Outcomes in Group A, 3 years prior to policy implementation, were compared with groups 2 and 7 years post implementation (Groups B and C). Primary outcomes were representations to ED, admission rate and time to cholecystectomy. RESULTS: A total of 584 patients presented with biliary colic during the three study periods. Of these, 391 underwent cholecystectomy with three Strasberg Type A bile leaks and no bile duct injuries. The policy increased admission rates (A = 15.8%, B = 62.9%, C = 29.5%, P < 0.001) and surgery on index presentation (A = 12.0%, B = 60.7%, C = 27.4%, P < 0.001). There was a decline in time to cholecystectomy (days) (A = 143, B = 15, C = 31, P < 0.001), post-operative length of stay (days) (A = 3.6, B = 3.2, C = 2.0, P < 0.05) and representation rates to ED (A = 42.1%, B = 7.1%, C = 19.9%, P < 0.001). There was a decline in policy adherence in the later cohort. CONCLUSION: Index hospital admission and cholecystectomy for biliary colic decrease patient representations, time to surgery, post-operative stay and complications of gallstone disease. This study demonstrates the impact of the policy with initial improvement, the dangers of policy attrition and the need for continued reinforcement.

Improving emergency surgical care for patients with right iliac fossa pain at a regional scale: A quality improvement study using the Supported Champions implementation strategy.

INTRODUCTION: Methods to improve clinical systems safety suffer from significant difficulties in implementation and scaling up. We used an upscaling implementation strategy entitled Supported Champions in a quality and safety improvement programme for emergency surgery at regional level, focusing on patients with right iliac fossa pain. METHODS: A before-after study was conducted across four acute NHS Trusts: A 6 month intervention phase was preceded and followed by 3 months of data collection. An established Human Factors intervention was led at each Trust by a small group of staff selected as Champions. Champions received training in teamwork and systems improvement and were supported by Human Factors experts. The primary improvement aim was to expedite surgery for patients with sepsis, using Royal College of Surgeons emergency surgery guidelines as the measure. Additional outcomes studied included length of inpatient stay and 30-day readmission rates. RESULTS: Breaches of RCS urgency guidelines decreased markedly from 13.7% of operated patients pre-intervention to 3.5% post-intervention (p = 0.000). Mean time from booking to incision decreased in three of the four sites, whilst median length of stay increased in 3 of 4. Overall 30-day readmission rate remained stable (7.84% pre-intervention versus 7.31% post-intervention, p = 0.959). DISCUSSION: The Supported Champions model allowed all surgical teams to reduce delay for septic patients by more than 50%, using distinct Quality Improvement strategies to address local issues. Improvement was implemented in 4 diverse settings with a quarter of the level of expert input previously used in a single hospital.

Thrombosed varicocele - a rare cause for acute scrotal pain: a case report.

BACKGROUND: Acute scrotal pain has various causes. Testicular torsion, torsion of appendages and Epididymo-orchitis are common causes, while varicocele thromboses are a rare cause. Varicocele thromboses can occur post operatively or spontaneously. Five cases of post-operative and five cases of spontaneous thromboses have been described till date. The traditional advice in the management of thrombosed varicocele has been to manage it conservatively in all patients by drugs and scrotal support with little description of the surgical treatment. Herein, we present an unusual sixth case of spontaneous thromboses of varicocele and discuss its presentation and surgical management. We would also like to highlight the differentiating points between spontaneous thrombosis and post operative in vitro clot formation in the varicoceles, as these two entities can often be confused for each other. CASE PRESENTATION: A 68 year-old man presented with excruciating scrotal pain of one week duration. Doppler study of scrotum revealed left varicocele with no evidence of Epididymo-orchitis. He was treated with intravenous antibiotics, analgesics and scrotal elevation. He had no relief and continued to have severe pain. Clinical examination was normal. Patient underwent exploratory surgery on a semi- emergent basis. Exploration revealed normal testis with thrombosed varicoceles. Patient underwent Varicocelectomy. Postoperatively patient had immediate pain relief. Histopathology revealed prominent thrombosed varicocele. A varicocelectomy specimen (done for primary infertility) was used for comparison. The differentiating points between the two entities were noted. CONCLUSION: Spontaneous thrombosis of varicocele is a rare cause of acute scrotal pain. Pain out of proportion to clinical features is characteristic. Patients not responding to medical therapy may need varicocelectomy. Varicocelectomy may give immediate relief. Histopathology is useful in this disorder.
