We reported a case of irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.The patient complained about a right groin mass for more than 60 years with progressive enlargement for 3 years and pain for half a month.Abdominal CT examination at admission showed rectum and sigmoid colon hernia in the right inguinal area and thickening of sigmoid colon wall.Electronic colonoscopy and pathological diagnosis showed sigmoid colon cancer.Therefore,the result of preliminary diagnosis was irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.We converted laparoscopic exploration to laparotomy followed by radical sigmoidectomy and employed end-to-end anastomosis of descending colon and rectum in combination with repair of right inguinal hernia.The patient recovered well after operation and was discharged.

OBJECTIVE: To evaluate the technical feasibility of intranodal lymphangiography and thoracic duct (TD) access in a canine model.MATERIALS AND METHODS: Five male mongrel dogs were studied. The dog was placed in the supine position, and the most prominent lymph node in the groin was accessed using a 26-gauge spinal needle under ultrasonography (US) guidance. If the cisterna chyli (CC) was not opacified by bilateral lymphangiography, the medial iliac lymph nodes were directly punctured and Lipiodol was injected. After opacification, the CC was directly punctured with a 22-gauge needle. A 0.018-in microguidewire was advanced through the CC and TD. A 4-Fr introducer and dilator were then advanced over the wire. The microguidewire was changed to a 0.035-in guidewire, and this was advanced into the left subclavian vein through the terminal valve of the TD. Retrograde TD access was performed using a snare kit.RESULTS: US-guided lymphangiography (including intranodal injection of Lipiodol [Guerbet]) was successful in all five dogs. However, in three of the five dogs (60%), the medial iliac lymph nodes were not fully opacified due to overt Lipiodol extravasation at the initial injection site. In these dogs, contralateral superficial inguinal intranodal injection was performed. However, two of these three dogs subsequently underwent direct medial iliac lymph node puncture under fluoroscopy guidance to deliver additional Lipiodol into the lymphatic system. Transabdominal CC puncture and cannulation with a 4-Fr introducer was successful in all five dogs. Transvenous retrograde catheterization of the TD (performed using a snare kit) was also successful in all five dogs.CONCLUSION: A canine model may be appropriate for intranodal lymphangiography and TD access. Most lymphatic intervention techniques can be performed in a canine using the same instruments that are employed in a clinical setting.

Varicocele is the dilatation of the scrotal portion of pampiniform plexus and the internal spermatic venous system. About 15% of men suffer from scrotal varicocele and 2% to 10% of them complain of pain. The probable mechanisms for pain include compression of the surrounding neural fibers by the dilated venous complex, elevated testicular temperature, increased venous pressure, hypoxia, oxidative stress, hormonal imbalances, and the reflux of toxic metabolites of adrenal or renal origin. Testicular pain associated with varicoceles is typically described as a dull, aching, or throbbing pain in the testicle, scrotum, or groin; rarely, it can be acute, sharp, or stabbing. The management of testicular pain associated with varicocele starts with a conservative, non-surgical approach and a period of observation. Varicocelectomy in carefully selected candidates with clinically palpable varicocele resolves nearly 80% of all cases of testicular pain. Microsurgical techniques for varicocelectomy have gained popularity with minimal complication rates and favorable outcomes. The grade of varicocele, the nature and duration of pain, body mass index, prior conservative management, and the type of surgical method used, are predictors for the success of varicocelectomy.

PURPOSE: Catheter ablation for atrial fibrillation (AF) requires heavy anticoagulation and uncomfortable post-procedural hemostasis. We compared patient satisfaction with and the safety of unilateral groin (UG) puncture-single trans-septal (ST) ablation with conventional bilateral groin (BG) puncture-double trans-septal (DT) ablation in paroxysmal AF patients. MATERIALS AND METHODS: We enrolled 222 patients with paroxysmal AF (59.4±10.7 years old) who were randomized in a 2:1 manner into UG-ST ablation (n=148) and BG-DT ablation (n=74) groups. If circumferential pulmonary vein isolation could not be achieved after three attempts of touch-up ablation in the UG-ST group, the patient was crossed over to BG-DT by performing a left groin puncture. RESULTS: Ten patients in the UG-ST group (6.8%) required crossover to the BG-DT approach. There were no significant differences in procedure time (p=0.144) and major complications rate (p>0.999) between the UG-ST and BG-DT groups. Access site pain (p=0.014), back pain (p=0.023), and total pain (p=0.015) scores were significantly lower for the UG-ST than BG-DT group as assessed by the Visual Analog Scale. Over 20.2±8.7 months of follow up, there was no difference in AF recurrence free-survival rates between the two groups (Log rank, p=0.984). CONCLUSION: UG-ST AF ablation is feasible and safe, and was found to significantly reduce post-procedural hemostasis-related discomfort, compared to the conventional DT approach, in patients with paroxysmal AF.

OBJECTIVE: To determine whether an active rehabilitation program that involves repetitive effortful muscle contractions, including core stability, balancing exercises, progressive resistance exercises, and running activities, after a sports hernia, is effective. METHODS: Forty soccer players with sports hernias were randomly divided into two equal groups: group A (active rehabilitation program) and group B (conventional treatment). The methods of assessment included a visual analog scale (VAS) and hip internal and external range of motion assessments. Group A received conventional treatment (heat, massage, transcutaneous electrical nerve stimulation, and mobilization) plus an active rehabilitation program, while group B received only conventional treatment. Three treatment sessions were given each week for 2 months. Evaluations were performed pre- and post-treatment. RESULTS: A decrease in VAS was seen in both groups at the end of treatment, 80.25% in group A and 41.93% in group B. The difference between the two groups was statistically significant (p=0.0001), whereas there were no statistical differences in internal and external rotation between the groups at the end of treatment (p>0.05). After treatment, an improvement in outcome measures of group A compared to group B (p=0.01) was seen. Thirteen patients in group A and only three patients in group B returned to sports activities without groin pain. CONCLUSION: Active rehabilitation was effective for sports hernia management measured by a decrease in pain and the return to sports.

BACKGROUND: The aim of this study was to assess the safety of one-per-mil tumescent injections into viable skin flaps that had survived an ischemic insult, in order to assess the potential suitability of one-per-mil tumescent injections in future secondary reconstructive procedures such as flap revision and refinements after replantation. METHODS: Forty groin flaps harvested from 20 healthy Wistar rats weighing 220 to 270 g were subjected to acute ischemia by clamping the pedicle for 15 minutes. All flaps showing total survival on the 7th postoperative day were randomly divided into group A (one-per-mil tumescent infiltration; n=14), group B (normal saline infiltration; n=13), and group C (control, with no infiltration; n=13) before being re-elevated. Transcutaneous oxygen tension (TcPO₂) was measured before and after infiltration, and changes in TcPO₂ were statistically analyzed using analysis of variance, the paired t-test, and the independent t-test. The viability of flaps was also assessed using the Analyzing Digital Images software at 7 days after the second elevation. RESULTS: Thirty-nine flaps survived to the final assessment, with the sole exception of a flap from group A that did not survive the first elevation. TcPO₂ readings showed significant decreases (P<0.05) following both one-per-mil tumescent (99.9±5.7 mmHg vs. 37.2±6.3 mmHg) and normal saline (103±8.5 mmHg vs. 48.7±5.9 mmHg) infiltration. Moreover, all groin flaps survived with no signs of tissue necrosis. CONCLUSIONS: One-per-mil tumescent infiltration into groin flap tissue that had survived ischemia did not result in tissue necrosis, although the flaps experienced a significant decrease of cutaneous oxygenation.

PURPOSE: Short-term outcomes following cemented and cementless hemiarthroplasties (HAs) are reported to be comparable, however, long-term outcomes of cementless HA—especially among Asian patients—is limited. We aimed to assess long-term outcomes in elderly East-Asian patients with intracapsular proximal femoral fractures treated with cementless HA. MATERIALS AND METHODS: We enrolled 135 patients treated with cementless HA who met our inclusion criteria. We documented bone/implant-related complications (e.g., incidences of revision hip surgery, femoral stem subsidence, dislocation, intraoperative and postoperative periprosthetic fractures, contralateral hip fractures). We included those patients who are still alive 10 years after the index surgery in the final functional analysis of the existence of pain, ambulatory status, and residential status. RESULTS: The mean age at injury was 78.3 years (range: 60–85 years). At the 10-year follow-up, 26 of the original patients (19.3%) had survived. During follow-up, revision hip surgery was conducted in two patients (1.5%). We recorded the incidence of intraoperative fractures, postoperative periprosthetic fractures, and contralateral fractures in two (1.5%), eight (5.9%), and six patients (4.4%), respectively. Among the 10-year survivors, six patients (23.1% of the survivors) complained of groin pain, but generally reported the pain to be tolerable. CONCLUSION: Among elderly East-Asian patients, the incidence of revision surgery after cementless HA may be lower than that in their European counterparts, whereas the incidence of periprosthetic fractures can still be considerably higher. For patients undergoing cementless HA, prevention of such secondary fractures is of critical importance.

PURPOSE: The outcomes of endovascular aneurysmal repair (EVAR) for infrarenal abdominal aortic aneurysms (AAAs) in the Middle East have rarely been reported. We analyzed the outcomes of EVAR in a Jordanian population.MATERIALS AND METHODS: We conducted a retrospective review of the medical records of patients with infrarenal AAA who were treated with elective EVAR between January 2004 and January 2017 at a single center in Jordan. Patient characteristics, anatomical characteristics, procedural details, and early and late postoperative outcomes were analyzed.RESULTS: A total of 288 patients (mean age, 70 years; 77.8% males) underwent EVAR for infrarenal AAA (median aneurysm size, 64 mm). Bifurcated endografts were used in 265 patients, and aorto-uni-iliac devices were used in 22 patients. Successful endograft deployment was achieved in all patients with no open conversion. Early complications included localized groin hematoma in 15, femoral artery dissection in 4, wound infection in 3, and seroma in 3 patients. With a mean follow-up of 60 months, 50 endoleaks were detected, including 9 type I, 38 type II, and 3 type III. Seven patients had unilateral graft limb occlusion. The 30-day mortality was 1.7%, and long-term mortality was 7.0%, mostly due to non-AAA-related causes.CONCLUSION: EVAR was safely performed in Jordanian patients with minimal complications. However, long-term surveillance is important due to the risk of endoleaks and consequent intervention.

Treacher Collins syndrome is a congenital disorder that is characterized with a wide range of cranio-facial deformities. Zygomatic hypoplasia or aplasia is one of the key features, and surgical reconstruction of the consequent depression on the zygomatic area is deemed necessary by many patients. Various surgical options are available—injectables, alloplastic materials, autologous grafting, and autogenous tissue transfer. It depends on each patient which technique to use. Here, we present a clinical case, in which bilateral free groin flaps were adopted in attempt to resolve the remnant aesthetic deformity associated with zygomatic depression, despite a series of previous surgical efforts, in a 25-year-old Treacher Collins syndrome male patient.

BACKGROUND: Large-scale muscle tissue engineering remains a major challenge. An axial vascular pedicle and perfusion bioreactor are necessary for the development and maintenance of large-scale engineered muscle to ensure circulation within the construct. We aimed to develop a novel experimental model of a large-scale engineered muscle flap from an existing rat groin fat flap. METHODS: A fat flap based on the superficial inferior epigastric vascular pedicle was excised from rats and placed into a perfusion bioreactor. The flaps were kept in the bioreactor for up to 7 weeks, and transdifferentiation of adipose to muscle tissue could have taken place. This system enabled myogenic-differentiation medium flow through the bioreactor at constant pH and oxygen concentration. Assessment of viability was performed by an immunofluorescence assay, histological staining, a calcein-based live/dead test, and through determination of RNA quantity and quality after 1, 3, 5, and 7 weeks. RESULTS: Immunofluorescence staining showed that smooth muscle around vessels was still intact without signs of necrosis or atrophy. The visual assessment of viability by the calcein-based live/dead test revealed viability of the rat adipose tissue preserved in the bioreactor system with permanent perfusion. RNA samples from different experimental conditions were quantified by spectrophotometry, and intact bands of 18S and 28S rRNA were detected by gel electrophoresis, indicating that degradation of RNA was minimal. CONCLUSIONS Flow perfusion maintains the long-term viability of a rat groin engineered muscle flap in vitro, and a large-scale vascularized muscle could be engineered in a perfusion bioreactor.
