Bilateral Rotational S Flap Technique for Preventing Restenosis in Patients With Severe Circular Anal Stenosis: A Review of 2 Cases.

Anal stenosis is a late hemorrhoidectomy complication. Sphincterotomy and various anoplasty techniques are used for treatment severe anal stenosis, such as the C flap, House flap, U flap, and rotational S flap, but no procedure is ideal for every patient. We review 2 cases of severe circular anal stenosis. Their complaints included narrow caliber of the stool and feeling unsatisfied defecation. Excision of scar tissue using the circular technique was followed by reconstruction using the bilateral rotational S flap procedure. At the 1-year follow-up, the patient had complaints about neither defecation nor pain, and no longer needed laxative agents. In conclusion, the bilateral rotational S flap technique should be considered as a viable treatment because it can also prevent the occurrence of restenosis, especially given the consideration of adequate blood supply.

Abdominosacral Resection in the Management of Large-Size Retrorectal Tumors: A Report of 2 Rare Cases.

Management of large-size retrorectal gastrointestinal stromal tumors (GISTs) is complex and challenging from diagnosis to treatment. This may create technical difficulties in surgical access and complete resection of the tumor. The abdominosacral resection has the benefit of improved visualization via the anterior incision, with enhanced exposure of the midrectal area, which makes resecting the tumor completely via the posterior approach easier. We report 2 cases of patients with a retrorectal GIST and neurofibromatosis type 1, one in a 27-year-old woman with a defecation complaint and the other in a 58-year-old woman with a defecation and urination complaint. Based on the anatomical pathology, both patients were diagnosed with a GIST. The tumors were excised via an abdominosacral resection. Retrorectal GISTs are rare, and abdominosacral resection allows complete resection of a large-size retrorectal GIST with low morbidity and an absence of functional impairment. The abdominosacral resection should be considered in certain situations.

Side-to-Side Ileosigmoidostomy Shunting Surgery for the Treatment of Elderly Patients With Chronic Constipation.

Constipation is a digestive disorder that often occurs in the elderly; its main cause is bowel motility disorder. Treatments for patients with chronic constipation include pharmacotherapy, diet changes, and surgery if other therapies do not offer satisfactory results. We describe 4 patients, 2 men (70 and 65 years old) and 2 women (75 and 66 years old), who were diagnosed with chronic constipation (slow transit constipation) and treated with conventional therapy, but did not improve. For that reason, side-to-side ileosigmoidostomy shunting surgery was performed. After the surgery, the average time until normal defecation was 16 days, and the defecation frequency was 3 to 4 times a day with no need for a laxative. No patient had a recurrence of constipation. Based on these results, side-to-side ileosigmoidostomy shunting surgery is expected to restore digestive function and can be considered as an alternative therapy for elderly patients with chronic constipation.

Ileocolonic Transposition Esophagogastric Bypass as an Antireflux Treatment for Corrosive Esophageal Injury.

Because most surgeons perform an esophagectomy and colonic transposition as the main reconstruction method for patients with esophageal stenosis caused by swallowing corrosive materials, we report 2 cases in which ileocolonic transposition was used to treat such patients. Both patients displayed stenosis in the middle third of the esophagus. Their chief complaint was dysphagia. Ileocolonic transposition using vascularization of the Drummond and ileal arteries was followed by a prepared ileocolic graft by ligating ileocolic vessels. We performed an ileocolonic transposition esophagogastric bypass without an esophagectomy. All surgeries resulted in minimal intraoperative bleeding. Patients experienced no leakage, postoperative fistulas, dysphagia, or postoperative reflux. Three weeks after surgery, 1 patient experienced reversible hoarseness caused by extensive laryngeal-nerve manipulation. Cumulatively, ileocolonic transposition with cervical anastomosis for the treatment of patients with esophageal stenosis caused by corrosive esophageal injury can be considered to be an antireflux treatment because the ileocaecal sphincter is maintained.
