Total subcutaneous fistulectomy combined with Karydakis flap for sacrococcygeal pilonidal disease with secondary perianal opening.

OBJECTIVE: Flap techniques have been performed with success in the treatment of pilonidal disease. However, some complex cases such as perianal pilonidal disease need special attention. We describe a modification of a well-known flap technique for secondary perianal pilonidal disease and its early results. PATIENTS AND METHOD: Total subcutaneous fistulotomy combined with Karydakis flap was performed on 14 patients. An elliptical incision, described by Karydakis, was made while not including the perianal opening. Both sides of the elliptical incision were deepened down to the gluteal muscle and postsacral fascia. At the level of subcutaneous tissue, attention was directed to the secondary perianal opening. A fine probe was inserted through the perianal skin pit, and the connection site between the fistula and the cyst was observed. A small circular skin incision was made around the probe and the fistula tract was totally excised using electrocautery together with the main cyst. The flap was prepared as described by Karydakis. Before suturing the flap to the other side, perianal subcutaneous tissue was sutured with a fine absorbable material, then, the flap was sutured with 4/0 polypropylene. RESULTS: One patient developed seroma. Neither early failure in wound healing nor recurrence was observed at a mean of 16.2 months (range 4-36 months) follow-up. CONCLUSION: Total subcutaneous fistulectomy plus Karydakis flap as a single-stage procedure is an effective surgical modality for sacroccocygeal pilonidal disease with secondary perianal opening.

Combined transurethral resection of prostate and inguinal mesh hernioplasty.

We aimed to evaluate the difference among early post-operative morbidities of transurethral resection of prostate (TURP), inguinal herniorrhaphy and their combination in this study. Between 1998 and 2004, 44 patients undergoing combined inguinal herniorrhaphy and TURP (Group I) were compared with 50 consecutive cases of TURP alone (Group II) and 50 consecutive cases of inguinal herniorrhaphy alone (Group III). There were no differences in the mean age and mean prostatic volume between Group I and II. The mean operation time and length of hospital stay were 126.1 +/- 20.9 min, 3.0 +/- 0.7 days for Group I, 61.4 +/- 15.6 min and 2.9 +/- 0.69 days for Group II and 55.0 +/- 15.6 min and 1.2 +/- 0.4 days for Group III, respectively. The mean operation time of Group I was found as longer than Group II and III. There were no significant differences among all groups regarding post-operative complications. No mesh infection was detected. Combined TURP and inguinal herniorrhaphy is a practical, safe and effective procedure.

Urinary retention after elective cholecystectomy.

BACKGROUND: There are few reports about urinary retention rate after elective cholecystectomy. We designed a prospective study to assess the problem. METHODS: A total of 121 female and 19 male patients were included in the study with a prospective study protocol. Laparoscopic cholecystectomy was performed in 107 patients and open cholecystectomy in 33 patients. RESULTS: Neither gender nor age affected rate. Postoperative micturition difficulty developed in 10 patients. Of these patients, 9 could void with helping measures, and only 1 needed catheterization. Only 1 patient who underwent laparoscopic surgery required catheterization (0.7%). The open approach caused a higher incidence of postoperative micturition difficulty than did the laparoscopic approach (15.2% versus 4.7%; P = 0.04). Only large amounts of perioperative fluid administration and meperidine use had statistically significant effects on micturition problems. CONCLUSIONS: Urinary retention is a rare complication after elective cholecystectomy. Helping measures are very effective and should be tried before inserting a urethral catheter.

Adult intussusception due to a malignant polyp: a case report.

Intussusception is primarily a disease of childhood; only about 5 to 10 per cent of cases occur in adults. In contrast to childhood intussusception 90 per cent of adults have an associated pathologic process, usually a malignant lesion. Adult cases do not have the classical symptoms and diagnosis may be difficult. CT scan and barium studies are the most useful diagnostic methods. We report a very rare case of adult ileocecocolic intussusception caused by a pedunculated malignant polyp of the cecum and review the clinical features of intussusception.

Thyroxine prophylaxis after bilateral subtotal thyroidectomy for multinodular goiter.

In this study, we investigated the value of thyroxine administration to prevent recurrence after bilateral subtotal thyroidectomy for multinodular goiter. Patients that had benign multinodular goiter were operated on with the same surgical principles: ligation of both superior and inferior thyroid arteries on both sides, bilateral subtotal resection of thyroid gland including all visible nodules. On the 3rd postoperative day, the patients were divided into two groups: with 100 microgram 1-thyroxine daily (Thyroxine group) or no therapy (Control group). No recurrences were encountered among 40 patients followed up for 6 months and 20 patients for at least one year. One patient in the control group developed manifest hypothyroidism (5.3%). The mean TSH level of the control group was significantly higher than that of thyroxine group at 1st, 2nd, 3rd, 4th, 5th, 6th, and 12th months. At the end of the first year, the mean TSH level of the control group was four times that of the normal. On the other hand, the mean TSH level of the thyroxine group was within normal limits but not suppressed. In conclusion, we found that the pituitary-thyroid axis did not become normal spontaneously one year after thyroidectomy. Therefore, postoperative thyroxine administration seems to be of value, especially in endemic regions like Turkey.

Comparison of direct trocar and veress needle insertion in the performance of pneumoperitoneum in laparoscopic cholecystectomy.

Veress needle insertion, direct trocar insertion and open technique are different methods of establishing pneumoperitoneum to perform a successful laparoscopic procedure. We conducted this study to compare the use of a Veress needle and direct trocar insertion to create pneumoperitoneum. 274 laparoscopic cholecystectomy operations were evaluated. There were no significant differences in the age and gender between Veress needle and direct trocar entry groups. In this study we have seen that the complication rate while performing pneumoperitoneum by direct trocar entrance was less than in Veress needle usage. Direct trocar entrance also reduces the operation time. In laparoscopic cholecystectomy the direct trocar entrance method is a more reliable and less time consuming method than Veress needle usage.
