Laparoscopic surgery may reduce the inflammatory response to surgery by the avoidance of a skin incision which is frequently the site of maximum tissue trauma. We hypothesized that the inflammatory response is less with minimally invasive procedures. The aim of this study was to evaluate the response of inflammatory mediators following laparoscopic and open hernia repair. Thirty-four patients undergoing unilateral primary inguinal hernia repair were prospectively assigned to either laparoscopic mesh hernia repair (n = 14), open mesh hernia repair (n = 11), or a Bassini repair (n = 9). Serum samples withdrawn prior to surgery, 6 h after surgery, and then again at 24 h after surgery were assayed for interleukin-6 and C-reactive protein content. Interleukin-6 levels at 24 h in the laparoscopic (13.1 +/- 3.1 pg/ml), open mesh (15.5 +/- 2.5 pg/ml), or Bassini group) (15.4 +/- 2.0 pg/ml) did not differ significantly. Neither did C-reactive protein levels at 24 h in the laparoscopic (12.4 +/- 2.7 pg/ml), open mesh (23.0 +/- 7.8 pg/ml), or Bassini group 18.6 +/- 6.6 pg/ml) differ significantly. The response of inflammatory mediators to hernia repair is not modified by undertaking the procedure laparoscopically.

A prospective comparison of metabolic and inflammatory responses after laparoscopic and open inguinal hernia operations was undertaken. There were 10 patients in each group. Plasma levels of cortisol, growth hormone, prolactin, C-reactive protein (CRP) and interleukin-6 (IL-6) were measured preoperatively and at fixed intervals up to 120 h postoperatively. In vitro, endotoxin stimulated whole blood tumour necrosis factor alpha (TNF alpha) was measured in preoperative and 24 h postoperative blood samples. Changes in the plasma levels of cortisol, growth hormone and prolactin showed no statistically significant difference between the groups. No significant change in IL-6 levels were recorded in any group. Changes in CRP levels were significantly higher (P < 0.006) in open hernia patients. Endotoxin stimulated TNF alpha production was suppressed in both groups. The degree of suppression in open hernia patients was significantly higher (P < 0.005). This study has shown that both these operations produce similar stress responses. However, open hernia operation results in a higher acute phase response and induces a greater endotoxin tolerance.

Although tension-free techniques of hernia repair using synthetic meshes have yielded encouraging results, the best method of inguinal hernia repair is still unclear. The aim of this study was to compare the responses of inflammatory mediators and postoperative pain relief following laparoscopic total extraperitoneal (TEP) hernioplasty, open tension-free mesh hernioplasty (Lichtenstein), posterior preperitoneal mesh hernioplasty (Nyhus procedure), and Bassini procedure. Patients with primary inguinal hernia were randomized in the operating room to undergo one of these repair techniques. Group I comprised 24 patients treated by Lichtenstein procedure; Group II comprised 21 patients treated by Nyhus procedure; Group III comprised 19 patients treated by Bassini procedure; and Group IV comprised 20 patients treated by laparoscopic TEP mesh hernioplasty. Postoperative pain levels following hernia repair were compared by measuring the use of patient-controlled analgesia (PCA) during the 24 hours after surgery. Serum samples withdrawn before surgery and 48 hours after surgery were assayed for C-reactive protein (CRP) content. Patient characteristics, operating time, and operative and early complications were noted. Serum CRP levels rose markedly following Nyhus (184.5 +/- 41.6 mg/L), Lichtenstein (138.4 +/- 72.5 mg/L), and Bassini repair (137.2 +/- 55.9 mg/L) compared with that of patients who underwent TEP mesh hernioplasty (55.5 +/- 41.2 mg/L). There were also significant differences in the postoperative need for analgesics via PCA among patients undergoing Nyhus (382.9 +/- 189.1 mg), Bassini (303.2 +/- 173.7 mg), and Lichtenstein (253.9 +/- 129.3) procedures compared with 196.6 +/- 148.8 mg for the TEP mesh hernioplasty group. Patients in the Lichtenstein group also had significantly less need of analgesics than those in the Nyhus and Bassini groups. In conclusion, TEP mesh hernioplasty is less traumatic and yields less postoperative pain than the Nyhus, Lichtenstein, and Bassini procedures.

Endoscopic techniques are commonly used for many different types of surgery. It is claimed that videoendoscopic procedures have the advantage of being less traumatic and of offering higher postoperative patient comfort than conventional open techniques. The extent of tissue trauma can be evaluated on the basis of the inflammatory response observed in the wake of surgery. Available studies that have compared endoscopic and conventional techniques suggest that endoscopic cholecystectomy, laparoscopic colorectal resection, and thoracoscopic pulmonary resection have immunologic advantages over conventional approaches. The objective of this prospective study was to determine whether endoscopic hernia repair techniques are also preferable to conventional procedures and to what extent the anesthetic technique (local or general anesthesia) influences the postoperative inflammatory response. For this purpose, biochemical monitoring of cytokine activity [C-reactive protein (CRP), prostaglandin F1alpha (PGF1alpha), neopterin, interleukin-6 (IL-6)] was done prospectively in 101 patients [totally extraperitoneal approach (TEP) n=32, unilateral n=12, bilateral n=20; Shouldice n=69, local anesthesia (LA) n=23, general anesthesia (GA) n=46] before and until 3 days after surgery. The parameters IL-6 and PGF1alpha suggested that the immune trauma immediately after surgery was significantly higher in the group of patients with endoscopic hernia repair than in the group of patients who received a Shouldice repair. No significant differences were observed after the first postoperative day. A comparison between the TEP group and the patients who received conventional surgery under local anesthesia showed that the TEP approach was also associated with a higher postoperative neopterin level. Within the first 3 days after surgical intervention, bilateral endoscopic hernia repair induced no significantly higher inflammatory response than the surgical treatment of unilateral conditions. The anesthetic procedure that was used in the Shouldice operation had no significant effect on inflammatory response. Unlike other types of endoscopic surgery, the repair of groin hernias using an endoscopic technique cannot be regarded as a minimally invasive procedure that is less traumatic than conventional approaches. Instead, the conventional Shouldice procedure appears to cause the lowest inflammatory response and to be the least traumatic approach to hernia repair, especially when it is performed under local anesthesia.

Surgical stress induces systemic endocrine-metabolic responses that influence the function of endothelial cells (EC) to cause various systemic reactions. Intercellular adhesion molecule (ICAM)-1 is an adhesion molecule that plays an important role in inflammation, and increased expression of ICAM-1 on EC is a reflection of EC activation. In this study, we investigated the ICAM-1 response to surgical stress in neonates undergoing major surgery. Fifteen neonates (mean age at surgery: 3.5 +/- 1.2 days) were divided into two groups according to indications for surgery: Group I: Congenital diaphragmatic hernia without persistent pulmonary hypertension (n = 5); Group II: Gastrointestinal surgery [n = 10: duodenal atresia (n = 3), intestinal atresia (n = 6), and esophageal atresia (n = 1)]. Serum samples were obtained preoperatively, immediately after completion of surgery (time zero), and 24, 48, 72, 96, and 120 h after surgery to measure ICAM-1 levels using an enzyme-linked immunosorbent assay, C-reactive protein (CRP), and white blood cell count (WBC). Postoperative recovery was uneventful in all cases. ICAM-1 levels in both groups increased significantly within 24 h of surgery (Group I: P = 0.0038, Group II: P = 0.0320). In Group I, ICAM-1 peaked 72 h postoperatively while in Group II it continued to rise until 96 h postoperatively. The difference between peak levels reached was not significant. CRP was first detected 24 h postoperatively in both groups and continued to increase until 48 h postoperatively. Again, the difference between peak levels reached was not significant. No significant changes in WBC were observed in either group. We found that ICAM-1 increases in response to surgical stress in neonates, although there was no significant difference in levels. However, surgical stress as represented by serum ICAM-1 would appear to last longer with intestinal surgery than with non-intestinal surgery. Further research is required to establish the usefulness of ICAM-1 as an easily detectable substance associated with endothelial damage that reflects the host's response to major surgical stress.

We present the second case of a broad ligament hernia to be treated by laparoscopy. A 43-year-old gravida 0, para 0 woman presented to our hospital with a chief complaint of right upper quadrant abdominal colicky pain and vomiting. Her clinical history was significant for an "unknown" bowel surgery through a Pfannenstiel incision. Her abdomen was soft, nondistended, and slightly tender to palpation in the right upper quadrant. The laboratory tests showed an elevated white blood cell count of 15.2 [1] 109/L with a left shift, and a normal serum C-reactive protein. Plain abdominal X-rays showed a lightly prominent small bowel loop in the pelvic area. An abdominal ultrasound revealed only a small amount of fluid in the pouch of Douglas. After 24 hours, the pain had migrated to the hypogastrium. There was an increase in the white blood cell count, in the C-reactive protein level, and in her temperature (37.7 degrees C). At this stage, we elected to perform an urgent laparoscopic exploration. We discovered 60-80 cm of ileum strangulated through a 2 x 3 cm defect in the left broad ligament of the uterus. The strangulated bowel was successfully reduced and the defect was closed with a 2-0 silk running suture. No bowel resection was required. The patient was discharged from the hospital on day 4, with no postoperative complications.

As a tension-free repair technique, Lichtenstein operation has gained great popularity worldwide during the last decade. Expert centres do this technique using local anaesthesia in nearly 95 % of cases. However, general anaesthesia is used in many hospitals, while regional anaesthesia is preferred in some centres. To date, no study has compared different types of anesthesia in respect of inflammatory response and oxidative stress specifically. The objective of this prospective study was to compare local, spinal and general types of anesthesia regarding their effects on inflammatory response and oxidative stress in Lichtenstein hernia repair. Lichtenstein hernia repair causes only a mild oxidative stress. While total WBC and neutrophil count responses fade away after 24 hours in patients who are operated under local anaesthesia, these changes in spinal and general types of anaesthesia cases stay valid at 24th hour. Spinal anaesthesia is seen to be more advantageous than local and general types of anaesthesia when C-reactive protein as an acute phase marker is considered. Total antioxidant status shows minor alterations in three types of anaesthesia, however, general anaesthesia seems to be the least reliable among them. Overall, local and spinal anaesthesia methods can be accepted as better alternatives in comparison with general anaesthesia in regard to oxidative stress (Tab. 2, Ref. 25).

Over the past decade, hernia surgery has undergone a considerable transformation with the use of prosthetic materials. The most used polypropylene meshes induce a rapid acute inflammatory response followed by chronic foreign body reaction. Many factors influence this response such as density, size, physical characteristics, different texture and porosity of each biomaterial. The aim of this study is to assess whether the implant of monofilament or multifilament meshes, in the inguinal hernioplasty, determine a different inflammatory response. Thirty-two male patients were included in the study and were randomly divided into two groups. In the first group (MO) inguinal hernioplasty was performed using monofilament polypropylene mesh, while in the second one (MU) multifilament prosthesis was used. Peripheral venous blood samples were collected 24 hours before surgery and then 6, 24, 48 and 168 hours post-operatively. Modifications in leukocyte count, C-reactive protein (CRP), alpha-1 antitrypsin (alpha1-AT), interleukin (IL)-1, IL-6, IL-1 ra and IL-10 serum levels were recorded at all sampling times. We present evidence that serum levels of CRP, (alpha1-AT), leukocytes and cytokines were significantly increased post-operatively in both groups, returning to basal values 168 hours afterwards. In particular, the production of all pro-inflammatory mediators was higher in the MU group, whereas the anti-inflammatory cytokine (IL-10, IL-1ra) production was higher in MO patients. Our results indicate that polypropylene multifilament mesh allows a higher intense acute inflammatory response as compared to monofilament mesh implantation.

Right lower quadrant (RLQ) pain is a common complaint in children presenting at emergency departments. This study analyzed the etiologies of RLQ pain, and compared the clinical presentations, laboratory test results and imaging findings in patients with appendicitis with those in other groups of patients. We also investigated if active observation resulted in delayed diagnosis, to the detriment of patients. Medical records for the period January 2006 to July 2006 were reviewed for children (age < 18 years) who presented to the emergency department of one medical center, complaining of RLQ pain. Out of a total of 100 patients (age range: 2-17 years; mean: 11 years), 46 patients presented with only one symptom of RLQ pain, while 32 patients had >/= 2 associated signs or symptoms, including fever, nausea/vomiting, diarrhea, or rebound tenderness. Imaging studies, including abdominal sonography and/or computed tomography, were performed in 73 patients; 44 underwent surgery for presumed appendicitis and one received surgery for a right paraduodenal hernia. Eleven patients underwent surgery because of peritoneal signs, and eight because of persistent or aggravated RLQ pain. Postoperative pathologic examinations revealed 53 cases of appendicitis, six normal appendices, and other morbidities (1 perforated peptic ulcer, 1 pelvic inflammatory disease, 1 ovarian cyst, 1 diverticulitis, and 1 right paraduodenal hernia). Thirty-three patients were discharged after several hours of observation (range: 0.5-18 hours; mean: 4 hours), and three patients were admitted for further observations. All were discharged without operation. There were significant differences in the incidences of fever (p = 0.004) and rebound tenderness (p = 0.019), and in white cell counts (p < 0.001), neutrophil percentages (p < 0.001), and C-reactive protein levels (p < 0.001) between patients with appendicitis and patients with other causes of RLQ pain. Clinical signs and symptoms, laboratory tests, and imaging studies can be used to differentiate between the causes of RLQ pain. Patients without the classical features of appendicitis or peritonitis can be safely managed by active observation and repeated physical examinations.

In this report, we discuss a case of a 14-month-old male presenting in the emergency department with refusal to bear weight on his left leg. Plain radiographic studies revealed no evidence of effusion, fracture, or dislocation. Laboratory studies were significant for an elevated white blood cell count, erythrocyte sedimentation rate, and C-reactive protein. Further studies included unremarkable ultrasound of the left hip and normal magnetic resonance imaging (MRI) of both hips. An incidental finding on MRI was a left inguinal mass concerning an incarcerated hernia. Ultrasound of this mass demonstrated a left undescended testis within the inguinal canal and possible incarcerated paratesticular inguinal hernia. The final pathologic diagnosis of a torsed gangrenous left testicle within the inguinal canal was confirmed during surgery.
