Seroma after laparoscopic repair of hernia with PTFE patch: is it really a complication?

We evaluated the true incidence of seroma formation after laparoscopic repair of incisional hernia with polytetrafluoroethylene (PTFE) patch. In a prospective study, 20 patients who underwent laparoscopic repair of incisional hernia with PTFE were evaluated clinically and with ultrasound examination for seroma formation up to the 90th postoperative day. Seroma was diagnosed clinically in only 35% of cases, while ultrasound examination revealed the presence of seroma in 100% of patients. Ultrasound examination is a reliable tool for diagnosis of early or delayed postoperative seroma formation following laparoscopic repair of incisional hernia with Gore-Tex Dualmesh.

Ureteric stent in severe hydronephrosis of pregnancy.

Eleven women (12 pregnancies) were included in the study. A double-pigtail ureteric stent was passed under cytoscopic vision in 8 patients. The mean gestational age on insertion of the stents was 29 weeks (range, 25-35 weeks). Delivery took place at a mean of 39 weeks (range, 35-41 weeks). Stents remained in situ for a mean of 9 weeks (range, 6-14 weeks) before delivery and were removed 4-5 weeks postpartum. Double pigtail ureteric stents did not expose the women to infection. Renal function tests remained within the normal limits. Ureteric stent is an effective method for internal drainage of severe hydronephrosis during pregnancy.

[Splenic hemorrhage masquerading as myeloproliferative disease].

While blunt trauma to the spleen may result in various clinical features, it sometimes may not cause symptoms. A 59-year-old man presented with fever 2 weeks after minor chest trauma. Initial investigation suggested a myeloproliferative disorder. However, abdominal ultrasonography established the diagnosis of subcapsular and intrasplenic hemorrhage. Management was conservative and he was discharged after 13 days.

[Well-differentiated thyroid carcinoma].

18 cases of well-differentiated thyroid carcinoma are described, of which 5 were papillary or mixed carcinomas and 3 were follicular. In 12 of 14 in whom radio-isotope scanning was performed, a cold or indeterminate nodule was found. Fine needle aspiration was positive and concordant with the operative histological findings in half the cases examined. In 4 hemithyroidectomy was performed, and in 14 total thyroidectomy. Thyroid remnants were found on scanning in all of the 14. These remnants were ablated with radioactive iodine (131I). An ablative dose of 30 millicurie was insufficient in almost all cases and a second dose was required. 3 cases with regional spread of the tumor were reoperated, and large ablative doses of 131I(150-170 mCi) were given. In 14 cases clinical remission was achieved. Followup included ultrasonography and total body 131I scans.

Bilateral hydronephrosis due to fecaloma in an elderly woman.

By computer search of the literature, we found few cases of hydronephrosis due to fecal impaction. Because such a complication is extremely rare, we describe an 81-year-old woman with dementia, gallstones, arterial hypertension, and diverticulosis of the sigma who was hospitalized for severe constipation, fecaloma, and bilateral hydronephrosis. Through simultaneous lavage by two rectal tubes and manual disimpaction of fecaloma, bilateral hydronephrosis was resolved. We also briefly review the appropriate literature.

Postappendectomy intra-abdominal abscess: a therapeutic approach.

Four hundred and sixty two children were operated on between January 1989 and June 1993 for acute appendicitis; 10 developed an intra-abdominal abscess. Intra-abdominal abscesses were accompanied by fever above 38 degrees C (nine out of 10 patients) and leucocytosis (mean leucocyte count 20.3 x 10(9)/l) and were detected sonographically four to 14 days after operation. Management included intravenous administration of antibiotics effective against both aerobes and anaerobes, and follow up with serial sonographic studies. Eight patients responded favourably to antibiotic treatment without any drainage procedure, with gradual shrinkage and collapse of abscesses. Two patients, in whom enlargement of collection was demonstrated on serial sonographic examination, eventually underwent percutaneous drainage under sonographic control. These results suggest that some paediatric patients with an intra-abdominal abscess after appendicectomy and who are followed up closely by sonography may be managed successfully with appropriate antibiotics alone.

Isolated splenic infarction following left cardiac catheterization: case report and a review of the literature.

A cardiac catheterization was performed in a 57-year-old man for post-infarction angina. A severe left flank pain developed following the angiography. Ultrasonography, computed tomography, and radionuclear scanning of the abdomen showed splenic infarction. An isolated cholesterol atheroembolism of spleen from disrupted atheromatous plaques so far has not been reported.

Benign cystic mesothelioma of the peritoneum: the occurrence of an adult entity in a child.

Benign cystic mesothelioma of the peritoneum is considered a disease of adulthood occurring predominantly in women. We report a case of benign cystic mesothelioma of the peritoneum in an 11-year-old boy. The innumerable cystic lesions that varied in size occupied the entire peritoneal cavity. He underwent two laparotomies in a period of 15 months during which a partial removal of the tumor was performed. Four years after the second operation the child is well and active, despite significant tumor tissue left behind after the first two operations. The management of this disease is discussed, and the importance of a conservative approach minimizing the number of laparotomies and avoiding radical surgical intervention especially in childhood is emphasized.

Prediction of difficult laryngoscopy in obese patients by ultrasound quantification of anterior neck soft tissue.

In 50 morbidly obese patients, we quantified the soft tissue of the neck from the skin to the anterior aspect of the trachea at the vocal cords using ultrasound. Thyromental distance, mouth opening, limited neck mobility, modified Mallampati score, abnormal upper teeth, neck circumference and sleep apnoea were assessed as predictors of difficult laryngoscopy. Of the nine (18%) cases of difficult laryngoscopy, seven (78%) had a history of obstructive sleep apnoea, compared with two of the 41 patients (5%) in whom laryngoscopy was easy (p < 0.001). Patients in whom laryngoscopy was difficult had more pretracheal soft tissue (mean (SD) 28 (2.7) mm vs. 17.5 (1.8) mm; p < 0.001) and a greater neck circumference (50 (3.8) vs. 43.5 (2.2) cm; p < 0.001). None of the other predictors correlated with difficult laryngoscopy. We conclude that an abundance of pretracheal soft tissue at the level of the vocal cords is a good predictor of difficult laryngoscopy in obese patients.
