AbstractPURPOSE: Botulinum toxin injection into the internal anal sphincter has been shown to be an effective treatment for chronic anal fissure. A randomized, prospective trial was conducted to compare botulinum toxin with lateral internal anal sphincterotomy as definitive management for chronic anal fissure. METHODS: Patients diagnosed as having chronic anal fissure were randomly assigned to one of the two treatment arms. In the botulinum toxin group (n = 61), 20 to 30 U (approximately 0.3 U/kg) of type A botulinum toxin (Botox®) was injected into the internal anal sphincter. The injection was repeated two months later if complete healing was not accomplished. Patients in the sphincterotomy group (n = 50) underwent lateral internal anal sphincterotomy. The same investigators evaluated the patients on postoperative/postinjection days 7 and 28, and then in a blinded manner at 2, 6, and 12 months. RESULTS: In the botulinum group, single injection resulted in complete healing in 45 of the 61 patients (73.8 percent) at the second month. Of the 16 failures, 6 patients refused further treatment, and 10 were treated with a second injection, which resulted in an overall healing rate of 86.9 percent (53/61) at 6 months. In the sphincterotomy group, the success rate was 82 percent (41/50) at day 28 and 98 percent (49/50) at the second month (P = 0.023 and P < 0.0001, respectively, compared with the botulinum group—single injection). At 6 months, 2 patients in the LIS group developed recurrences, and the healing rate was similar to that of the botulinum group (86.9 vs. 96.4 percent; P = 0.212). At 12 months, the success rate of the Botox® group fell to 75.4 percent (46/61) with 7 recurrences, whereas it remained stable in the sphincterotomy group (94 percent, P = 0.008). Sphincterotomy was associated with a significantly higher complication rate (8 cases of anal incontinence vs. none in the botulinum toxin group; P < 0.001). Full return to daily activities took significantly less time in the botulinum group (1 vs. 14.8 ± 5.7 days; P < 0.0001). CONCLUSION: Although the healing rate of chronic anal fissure is considerably high with botulinum toxin injection with earlier recovery and less complications compared with sphincterotomy, it occasionally requires a repeat injection, and the healing is slower. The early (two months) and late (one year) healing rates are significantly higher in the sphincterotomy group, the two groups reaching similar healing rates only at six months.

Purpose.To investigate the results of wide rhomboid excision with Limberg transposition flap reconstruction to treat pilonidal sinus.Methods.We analyzed the well-documented records of 238 patients with sacrococcygeal pilonidal sinus who underwent wide excision with a Limberg transposition flap and were followed up for longer than 1 year postoperatively. After the first 40 operations, we modified this flap reconstruction by tailoring the rhomboid excision asymmetrically to place the lower pole of the flap 1–2 cm lateral to the midline. Wound infection rates, hospitalization, time required for free mobilization, and recurrence rates were recorded.Results.Postoperative infection developed in two patients (0.8%), which was easily managed by wound care, antibiotics, removal of skin staples, prolonged drainage, or a combination of these treatments. The mean hospitalization was 2.10 ± 0.20 days (range 1–3 days), and the mean time required for recovery and return to daily activities was 8.00 ± 2.50 days (range 4–17 days). There were only three recurrences (1.26%) after a mean follow-up of 29.20 ± 3.10 months (range 12–38 months). Since we started performing our modification of the technique by lateralization of the inferior apex, no further recurrences have been seen. The recurrence rate differed significantly between the classical Limberg flap group and the modified Limberg flap group (P = 0.004)Conclusion.These results provide further evidence that wide excision with a Limberg transposition flap reconstruction is an effective surgical method for primary or recurrent pilonidal sinus, associated with a low complication rate, short hospitalization and disability, and a low recurrence rate. A modification of the technique was devised to further enhance wound healing and reduce the risk of recurrence.

Background: There is an ongoing need, from both the medical and the economic perspective, for a more accurate definition of the influence of symptomatic or asymptomatic gallstone disease on gastrointestinal symptomatology, as well as on the health of the individual in general. Methods: Using the Gastrointestinal Quality of Life Index (GIQLI), 37 symptomatic and 30 asymptomatic gallstone patients were evaluated at admission to the hospital and again 4 months after undergoing an uneventful laparoscopic cholecystectomy (LC). Results: Postoperatively, significant increases in the total GIQLI score were noted in both the symptomatic group (113.42 ± 21.9 vs 80.32 ± 19.1 preoperatively; p < 0.05) and the asymptomatic group (96.37 ± 14.26 vs 113.30 ± 15.22; p < 0.05). For the subgroups of items, the core symptoms and the physical, psychological, and disease-specific items improved significantly in both groups in the postoperative period (p < 0.05 for all comparisons), but only the symptomatic group achieved a significant improvement in the subgroup of social items (p < 0.05). Negative correlations were found in both the symptomatic and asymptomatic groups between the preoperative GIQLI scores and the improvement seen after LC (r = -0.70 and r = -0.49, respectively). Conclusion: Gallstone disease has a profoundly negative impact on quality of life, especially in symptomatic patients with a history of biliary colic attacks and/or the complications of the disease. Although the condition is not equally distressing for the asymptomatic group of patients without such a history, uncomplicated LC improves the quality of life significantly in both groups. Gallstone patients with lower GIQLI scores are more likely to benefit from LC.

PurposePilonidal sinus disease (PSD) is usually seen on the sacrococcygeal region in adolescent patients. The current study analyzed the outcome of the rhomboid excision and the Limberg flap procedure (cLF) in comparison to the modified Limberg flap procedure (mlF) for PSD.MethodsFour hundred and sixteen patients with PSD were operated on under spinal or general anesthesia by cLF and mlF. The patients were divided into two groups. In Group 1, cLF was performed on 211 patients. In Group 2, mlF was performed on 205 patients.ResultsNo significant difference was detected between Groups 1 and 2 in terms of sex, age, preoperative disease period, follow-up time, the mean hospital stay, and hypoesthesia. The mlF group had better clinical results than the cLF group. The recurrence rate was statistically higher in the cLF group 1 than in the mlF group (P = 0.036). The time to return to work, time to walk without pain, and time to be able to sit on the toilet without pain were longer in the cLF group (P = 0.001). The maceration and wound infection rate were statistically higher in the cLF group than in the mlF group (P = 0.020 and P = 0.019, respectively).ConclusionThe mlF is a more effective treatment than cLF for the surgical management of PSD.

BACKGROUND: Adhesion formation after peritoneal surgery is a major cause of postoperative bowel obstruction, infertility, and chronic pelvic pain. In this study, we compared the possible individual effects of phosphatidylcholine (PC), Seprafilm® II, and tissue plasminogen activator (t-PA) and the combined effects of phosphatidylcholine and t-PA on postoperative adhesion formation in a rat surgical model. MATERIALS AND METHODS: A total of 50 Wistar male rats underwent median laparotomy and standardized abrasion of the visceral and parietal peritoneum. phosphatidylcholine, Seprafilm II, and t-PA alone and phosphatidylcholine and t-PA in combination were applied intraperitoneally at the end of the surgical procedure. Seven days after surgery, a relaparotomy was performed for adhesion grading and histopathological examination. RESULTS: A comparison of adhesion stages demonstrated a significant difference between the control group and the study groups (p<0.001). The adhesion grade of the combined treatment group was statistically different from that of the other groups (p<0.05). In the t-PA group and the combined group, six and two rats, respectively, developed hematomas locally on the cecum. CONCLUSIONS: PC, t-PA, and Seprafilm II used individually reduced the adhesion grade. The t-PA and phosphatidylcholine combination was most effective in reducing adhesion formation. On the other hand, usage of t-PA alone or in combination may increase risk of bleeding. More detailed studies are needed, and future studies on the efficacy of a material for decreasing adhesion formation should include a comparison of several control materials in the same model.

The purpose of this study is to evaluate the operative outcomes of a gastric pull-up and free jejunal graft reconstruction after resection of hypopharyngeal and cervical esophageal carcinoma. Records of all patients who underwent esophageal resection for carcinoma of the hypopharynx and cervical esophagus were reviewed. Reconstruction after esophagectomy was performed using the gastric pull-up (n = 38) or free jejunal graft (n = 14) techniques. The hypopharynx was the most common primary tumor site for the free jejunal graft group, whereas the gastric pull-up group had lesions more frequently in the cervical esophagus (P < 0.05). Both operative time and blood loss in the gastric pull-up group were significantly longer and excessive than those of the free jejunal graft group (P < 0.05). The graft survival rate was 95% (32/34) in the gastric pull-up group and 93% (13/14) for the free jejunal transfer group. The overall leakage rate was 1.9% (1/52). Three patients died (6%) in the postoperative period. There was no significant difference with regard to operative morbidity and mortality between the gastric pull-up group and free jejunal graft group. In conclusion, both free jejunal graft and gastric pull-up are safe and effective methods for the immediate restoration of alimentary continuity.

Diaphragmatic rupture occurs in 0.8% to 3.6% of patients after blunt or penetrating thoracoabdominal trauma, and the preoperative diagnosis is difficult. The diagnosis of traumatic diaphragmatic rupture may be made on initial presentation or at any time later. Right-sided diaphragmatic rupture is rare and occurs in approximately 5% to 20% of all diaphragmatic disruptions. The incidence of herniation of the intra-abdominal organs into the pleural cavity is also low, observed in only about 19% of right-sided diaphragmatic ruptures. We present a case of right-sided traumatic rupture of the diaphragm diagnosed 15 years after the initial blunt trauma. A 22-year-old male patient fell 15 years before and was symptom-free since then. He was referred to our hospital with the signs of herniation of the right diaphragm, which was manifested in the chest x-rays. The definite diagnosis was made through thoracoabdominal computed tomography. The diaphragmatic rupture was repaired via abdominal approach.

Abstract.Some cases of idiopathic pruritus anu may be refractory to treatment with dietary and hygienic instructions and short-term topical medications. In this study, we documented our technique and results with methylene blue injection in a large series of patients with intractable idiopathic pruritus ani. The results of 30 adult patients with well-documented intractable idiopathic pruritus ani who were treated with intradermal methylene blue injection are reported. No antibiotic prophylaxis, anesthesia or sedation was used. A total of 15 ml of a 1% methylene blue solution was injected intracutaneously and subcutaneously in the affected perianal area. A second injection (rescue treatment) was offered one month later to patients who declared partial response, and follow-up was restarted. One month after injection, 24 patients (80%) were symptom-free, 5 declared partial remissions, and one patient still had the same degree of pruritus ani. Five patients with partial remission underwent a second methylene blue injection, which provided complete relief in four. Therefore, the early response rate was 80% with single injection and 93.3% (28 of 30) with the rescue treatment. At six months, three recurrences were noted, indicating to a success rate of 83.3% (25 of 30). At 12 months after treatment, 23 patients (76.7%) were symptom free. This study has shown that intradermal methylene blue injection is a safe, simple, fast and efficient method of treating intractable idiopathic pruritus ani.

BACKGROUND: Abdominal surgery can lead to postoperative intra-abdominal adhesions (PIAAs) with significant morbidity and mortality. This study compares the use of honey with a standard bioresorbable membrane (Seprafilm™) to prevent the formation of PIAAs in rats. METHODS: Thirty rats underwent laparotomy, and PIAAs were induced by scraping the cecum. The animals were divided into three groups, each containing ten rats. Group 1 (control) represented the cecal abrasion group, with no intraperitoneal administration of any substance. Group 2 (honey group) underwent cecal abrasion and intraperitoneal administration of honey. Group 3 (Seprafilm™ group) underwent cecal abrasion and intraperitoneal Seprafilm™ application. RESULTS: Group 1 exhibited higher adhesion scores for adhesions between the abdominal wall and the organs. Groups 2 and 3 had decreased adhesive attachments to the intra-abdominal structures. Compared to group 1, the incidence of adhesion formation was lower in both group 2 (p=0.001) and group 3 (p=0.001). The incidence of fibrosis was also lower in group 2 (p=0.016) and group 3 (p=0.063) compared to group 1. There was no significant difference between the histopathological fibrosis scores for the rats in group 2 and those in group 3 (p= 0.688). CONCLUSION: This study suggests that both honey and Seprafilm™ decrease the incidence of PIAAs in the rat cecal abrasion model. Although the mechanism of action is not clear, intraperitoneal administration of honey reduced PIAAs. The outcome of this study demonstrates that honey is as effective as Seprafilm™ in preventing PIAAs.
