Late complications of incisional hernias following prosthetic mesh repair.

BACKGROUND: Incisional hernias still continue to be a serious problem for surgeons. In this study, we aimed to investigate the effects of polypropylene mesh and mersilene mesh, which are frequently employed in incisional hernias, as well as the effects of their application techniques on late complications. METHODS: Two-hundred-sixty-four open abdominal hernia repairs were performed between 1986--2000, using prosthetic materials: polypropylene mesh and mersilene mesh were used in hernia repair. Mesh was placed as onlay, underlay and sandwich techniques. Follow-up data were obtained from medical records. RESULTS: Comparisons were made with respect to surgical techniques and to late complications such as recurrence, enterocutaneous fistula, intestinal obstruction, and infections. Enterocutaneous fistulas developed in two patients. Recurrence occurred in 6.4 per cent. Chronic infection and wound sinus formation occurred in 5 per cent. The causes of recurrence included smoking, cellulitis, chronic infection/sinus tract, upper abdominal localization, and obstruction. Fistula formation occurred in patients with no peritoneal prevention, which was statistically significant (p=0.012). Chronic infection/sinus tract was high in patients for whom mersilene mesh was used, and enterocutaneous fistula occurred in 2 patients. CONCLUSION: To prevent late complications, it is necessary to avoid the contact of mesh with bowel.

[Thromboembolic prophylaxis after major abdominal surgery].

PURPOSE: To investigate the efficacy of prophylaxis modalities after major abdominal surgery. PATIENTS AND METHODS: Patients who underwent major abdominal surgery between October 1998 and October 1999 were randomly divided into 3 groups. The patients in Group 1 received compression stockings, in Group 2 0.3 ml low-molecular weight heparin (nadroparine calcium 0.3 ml, 2850 IU AXa LMWH) subcutaneously and in Group 3 compression stockings and 0.3 ml LMWH. All symptomless patients evaluated with low extremity deep venous Doppler ultrasonography (DUSG), and patients who had pulmonary embolus (PE) suspicion evaluated with pulmonary scintigraphy. RESULTS: There were 91 patients in Group 1, 91 patients in Group 2 and 92 patients in Group 3. The mean age was 57.25 +/- 13.12, 54.53 +/- 13.54, and 53.65 +/- 13.28 respectively. Male/female ratio was 51/38, 56/35 and 62/30, in Group 1, 2 and 3 respectively. Twenty-seven patients in Group 1, 26 patients in Group 2 and 37 patients in Group 3 had risk factors. DUSG showed deep venous thrombosis (DVT) on the 7th postoperative day in 10 patients in Group 1, in 8 patients in Group 2 and in 3 patients in Group 3. Pulmonary scintigraphy showed PE suspicion in 6 patients in Group 1, 1 patient in Group 2 and 1 patients in Group 3. Wound hematoma and hemorrhage from abdominal drains were developed in 1/0, 8/2 and 3/1 patients in Groups 1, 2 and 3 respectively. Four patients in Group 1 and 2 patients in Group 2 died during the treatment (2.2%). Satistical analysis showed significant differences in PE and wound hematoma between Groups 1 and 2, in DVT and PE between Groups 1 and 3, in risk factors between Groups 2 and 3 (p < 0.05). The differences in DVT and PE and hematoma between group 2 and 3 were not significant. CONCLUSION: All treatment modalities could not prevent all thromboembolic complications. In our study combined treatment was the most effective one.

[Hepatic injuries. Surgical treatment experience].

PURPOSE: To evaluate the results of the surgical treatment of hepatic injuries in our institution for liver injuries. PATIENTS AND METHODS: One hundred seventy four patients who underwent operations between January 1986-December 1999 in Atatürk University Medical School, Emergency Service were reviewed retrospectively. RESULTS: 135 patients were male (77.5%). The mean age was 25.4 (range 3-84). Sixty three patients (36.3%) had only hepatic injuries and the others had co-existing abdominal organ injury [62 patients (35.7%) had one organ, 29 (16.7%) had two, 17 (9.7%) had three, 2 (1.1%) had four, and 1 (0.5%) had 5 organ injuries]. Five patients (2.8%) had inferior vena cava and 1 (0.5%) had vena porta injuries. One hundred seven patients (61.4%) had blunt, 44 (25.3%) had stab wound and 23 (13.3%) had gunshot injuries. Management was simple suture in 104 patient (60%), primary suture + surgical cell patching in 52 (29.8%), hepatectomy (5 right hepatectomy, 5 non anatomic hepatectomy) in 10 (5.7%), perihepatic packing in 4 (2.3%), primary suture + omental patch in 2 (1.1%), primary suture + arterial ligation in 2 (1.1%). Eleven patients (16.4%) in penetrating trauma group "Penetrating Abdominal Trauma Index" (PATI) score were higher than 25. Fever was the most common complaint postoperatively (5%). Three patients (1.7%) underwent reoperation. Twenty-six patients (14.9%) which one of them ware died. Died in the postoperative periods, 23 (13.2%) had blunt and 3 (1.7%) had penetrating traumas. CONCLUSION: Liver trauma still has high mortality rate injuries are very momentous. Especially blunt trauma related hepatic.

Posttraumatic gallbladder torsion in a child.

Torsion of the gallbladder in an 8-year-old boy, which was precipitated by blunt abdominal trauma from a ball-strike during a soccer game, is reported. Of the 13 reported childhood cases of gallbladder torsion, this is the first to be precipitated by blunt abdominal trauma in the presence of congenital anatomic predilection.

Intrabiliary rupture in liver hydatid cysts: results of 20 years' experience.

To assess the diagnostic tools and results of treatment of biliary rupture observed in liver cyst hydatids, clinical findings of 562 patients with hepatic hydatid disease were reviewed. Imaging techniques were not very effective to determine intrabiliary ruptures. Rates of rupture sizes determined in the patients were as follows; 22 (%24.7) large, 38 (%42.7) small, and 29 (%32.6) occult. Most frequently utilized procedures for patients with intrabiliary rupture were Roux-en-y cystojejunostomy, tube drainage + omentoplasty, sutured fistula + omentoplasty, and sutured fistula + tube drainage. Of the total 25 external biliary fistulas, 21 closed spontaneously. Of the four fistulas that did not close, one was managed by internal drainage and three by endoscopic sphincterotomy. Preoperative diagnosis of biliary rupture in liver hydatid cyst allows early planning of operation and helps the surgeon design the operative strategy. In the treatment of cases with large rupture, internal drainage may be proposed.

Intussusception in adults.

To review clinical, radiological and histopathological findings of adult intussusception and its management, 18 adult patients who had been treated surgically because of intussusception were reviewed. Of the patients, 5 (27.8%) had idiopathic intussusceptions, while the other 13 (72.2%) had a definable intraluminal pathology. The site of the intussusception was more common in the small bowel (83.3%) than the colon (16.7%). Ultrasonography and computed tomography were successful in demonstrating "target lesion" in 80% and 75% respectively. Patients with idiopathic intussusception were treated with simple reduction, while the others underwent segmental resection because of the possibility of malignant tumour. In contrast to intussusception in childhood, intussusception in adults usually has a definable lead point and resection of the involved bowel, rather than simple reduction, is indicated.

Fine needle aspiration biopsy in hepatic Echinococcus multilocularis.

OBJECTIVE: To determine the fine needle aspiration biopsy (FNAB) findings in hepatic Echinococcus multilocularis. STUDY DESIGN: FNAB and tru-cut liver needle biopsy were applied in 14 hepatic E multilocularis cases. Cytologic smears were stained with May-Grünwald-Giemsa and periodic acid-Schiff (PAS) stain. Tissue sections were stained with hematoxylin-eosin (HE) and PAS stain. RESULTS: In tissue sections, homogeneous, thin, cystic structures of various dimensions strongly stained with PAS. Mucoid material was stained with PAS in the cystic structures. Wide, coagulative necrosis was observed in all cases. In some cases there were foreign body-type giant cells at the periphery of the lesion. In all the cytologic smears there were an intense necrotic ground, PAS-positive hyaline cuticular structures and mucoid globules; in some cases there were foreign body-type giant cells. CONCLUSION: The above cytologic characteristics are basic diagnostic criteria for FNAB of E multilocularis.

Importance of psychiatric intervention in intolerances in endoscopic procedures.

Despite the fact that pre-medication, in a number of different drug combinations, has been used for a long time in endoscopy units, and has been subject to extended clinical studies, it is still not possible to claim that it has attained an ideal state with regard to patient tolerance to endoscopy procedures. In this clinical study, we have investigated the effects of psychological intervention in addition to medication, which we used on patients with intolerance to endoscopy. Intolerance was very high in all endoscopic procedures (15.8% total). It was observed that average midazolam doses were significantly higher in intolerant than in tolerant patients. It was found that in patients who had received psychiatric intervention, the decrease in midazolam dose was statistically significant in a subsequent endoscopy procedure.
