Communications of coronary arteries with the cardiac cavities have first time been described by Krause in 1865 in a case of an accessory artery draining into the pulmonary artery and later Cayla in a case of a right coronary artery entering the right ventricle. The initial cases have been found accidentally at autopsies, however In recent years after the Introduction of angiography and coronary arteriography, the malformation Is diagnosed during life and is corrected surgically. These conditions are unusual entitles since the advent of angiography they are being diagnosed with increasing frequency. Three patients who had surgical correction of coronary-cardiac chamber fistula at our hospital are presented. In the first case and second case, coronary arteriovenous fistula was corrected horizontal mattress suture ligation with pladget under the cardiopulmonary bypass and third case was corrected double ligation with cardiopulmonary bypass standby. The postoperative courses were uneventful. They discharged without any fistula related complica-tions.

Since the first report of an operation for prolapsed intervertebral disk by Mixter and Barr[1934], many thousands of operations have been successfully performed without incident. Linton and White in 1945 reported the vascular complication, but perforation of large vessels is rare complication of operation for prolapsed disk. A medical student, aged 22 years, was performed to a disk operation [L4-5, Rt. on May 1977.] From postoperative 10th day, palpitation, generalized edema and substernal pain were noted, and 2 months later, wide pulse pressure [70-80 mmHg], continuous bruit and thrill on the Rt. low abdomen were followed. Aortography revealed arteriovenous fistula between just proximal to abdominal aortic bifurcation and inferior vena cava. So, fistulectomy [Resection of proximal 2 cm of C.I.A., Rt, including fistula opening and end to end anastomosis] was performed on July, 77. During follow up study, remained fistula between Rt. internal lilac artery and lilac vein was found 2 months later. Re-operation [Double ligation of the Rt. internal lilac artery] was don on January 1978. Postop. results were excellent, except impossible to ejaculation.

Foreign bodies impacted in the maxillofacial region are often a diagnostic challenge. They can be a source of chronic inflammatory reactions and infections leading to the formation of an orocutaneous fistula. Such orocutaneous fistulas cause significant morbidity in most patients, eventually requiring surgery. Recently, we encountered a very rare case of an orocutaneous fistula caused by multiple foreign bodies in the cheek. Precise removal of the foreign bodies was required, and a double-sided anterolateral thigh free flap was used to reconstruct the defect. Surgeons should be aware of the complications of multiple foreign bodies and should be able to diagnose these on careful clinical examination.

Background Cleft lip and cleft palate are the most frequent congenital craniofacial deformities, with an incidence of approximately 1 per 700 people. Postoperative palatal fistula is one of the most significant long-term complications. This study investigated the incidence of postoperative palatal fistula and its predictive factors based on 25 years of experience at our hospital. Methods We retrospectively reviewed 636 consecutive palatal repairs performed between January 1996 and October 2020 by a single surgeon. Data from patients' medical records regarding cleft palate repair were analyzed. The preoperative extent of the cleft was evaluated using the Veau classification system, and the cleft palate repair technique was chosen according to the extent of the cleft. SPSS version 25.0 was used for all statistical analyses, and exploratory univariate associations were investigated using the t-test. Results Fistulas occurred in 20 of the 636 patients; thus, the incidence of palatal fistula was 3.1%. The most common fistula location was the hard palate (9/20, 45%), followed by the junction of the hard and soft palate (6/20, 30%) and the soft palate (5/20, 25%). The cleft palate repair technique significantly predicted the incidence of palatal fistula following cleft palate repair (P=0.042). Fistula incidence was significantly higher in patients who underwent surgery using the Furlow double-opposing Z-plasty technique (12.1%) than in cases where the Busan modification (3.0%) or two-flap technique (2.0%) was used. Conclusions The overall incidence of palatal fistulas was 3.1% in this study. Moreover, the technique of cleft palate repair predicted fistula incidence.

We report a rare case of gastric cancer presenting with a gastrocolic fistula during ramucirumab and paclitaxel combination therapy that was successfully managed with colonic stenting. A 75-year-old man was admitted to our hospital with the chief complaint of melena. Esophagogastroduodenoscopy revealed a large ulcerated tumor in the lower stomach, judged by laparoscopy as unresectable (sT4bN1M0). After four cycles of first-line chemotherapy with S-1 plus oxaliplatin, the patient showed disease progression, and second-line therapy with ramucirumab and paclitaxel was started. At the end of the third cycle, the patient had gastric antral stenosis, which necessitated the placement of a gastroduodenal stent. When the patient complained of diarrhea 10 days later, esophagogastroduodenoscopy revealed a fistula between the greater curvature of the stomach and the transverse colon. The fistula was covered by double colonic stenting, with a covered metal stent placed within an uncovered metal stent, after which leakage from the stomach to the colon stopped.

A 44-year-old woman underwent sleeve gastrectomy, which was complicated by a leak. She was treated with two sessions of endoscopic internal drainage using plastic double-pigtail stents. Her clinical evolution was favorable, but four months after the initial stent placement, she became symptomatic, and a gastrobronchial fistula with the proximal end of the stents invading the diaphragm was diagnosed. She was treated with antibiotics, plastic stents were removed, and a partially covered metallic esophageal stent was placed. Eleven weeks later, the esophageal stent was removed with no evidence of fistula. Inappropriate stent size, position, stenting duration, and persistence of low-grade inflammation could explain the patient's symptoms and provide a mechanism for gradual muscle rupture and fistula formation. Although endoscopic internal drainage is usually safe and effective for the management of post-laparoscopic sleeve gastrectomy leaks, close clinical and radiological follow-up is mandatory.

Purpose: The goal of palatoplasty is focused on two points. One is to close the palatal defect completely, and the other to create a velopharyngeal system for normal speech. While established methods such as pushback palatoplasty or double opposing Z palatoplasty are used in wide cleft palate repair, sequelae such as maxillary hypoplasia or oronasal fistula may result. Therefore, when palatoplasty with buccinator myomucosal flap is used in the case of wide cleft palates, maxillary hypoplasia and oronasal fistula is reduced and optimal results are obtained. Methods: From October 2005 to December 2006, four children with wide complete cleft palate underwent unilateral buccinator myomucosal flap and intravelar veloplaty. Mean age at cleft repair was 15 months, and mean cleft size was 2.15 cm. The patients underwent intravelar veloplasty and palatoplasty was done using unilateral buccinator myomucosal flap. Results: The patients, after mean 10 months of follow-up observation, showed no signs of oronasal fistula resulting from flap tension. The shape and color similar to normal oral mucosa was obtained, and velopharyngeal function was acquired. Conclusion: When intravelar veloplasty and palatoplasty with unilateral buccinator myomucosal flap is done on wide cleft palates, postoperative speech function is optimal, velopharyngeal incompetence is effectively corrected, and sequelae resulting from pushback palatoplasty and double opposing Z-plasty, such as maxillary hypoplasia and oronasal fistula, is reduced.

Euccal fat pad is special fat tissue which is different from subdermal fat. Anatomically, buccal fat pad is easy to harvest in the course of dental surgery procedure. In 1802, it was introduced by Bichat, Since Egyedi used buccal fat pad flap for the closure of oro-antral fistula and oro-nasal fistula, it has been widely used as an alternative method for the reconstruction of small to medium-sized intraoral defects in oral and mzxillofacial surgery. Kim et al. reported successful results in the all cases they applied buccal fat pad for the reconstruction of intraoral defect from their 31 months follow-up data. Because intraonal wounds are difficult to complete the layered suture and there are high risks of infection related with wound dental implant surgery, double layer closure using some kind of local flaps or other procedure is recommended. So we are to introduce the useful applications of the pedicled buccal fat pad in the dental surgery procedure from the various case presentations.

Complete colonic duplication is a very rare congenital anomaly that may have different presentations according to its location and size. Complete colonic duplication can occur in about 15% of all gastrointestinal duplications. Double termination of tubular colonic duplication in the perineum is even more uncommon. We present a case of a Y-shaped tubular colonic duplication which presented with a rectovestibular fistula and a normal anus. Radiological evaluation and initial exploration for sigmoidostomy revealed duplicated colons with a common vascular supply. Endorectal mucosal resection of theduplicated distal segment till the colostomy site with division of the septum of the proximal segment and colostomy closure proved curative without compromise of the continence mechanism. Tubular colonic duplication should always be ruled out when a diagnosis of perineal canal is considered in cases of vestibular fistula alongwith a normal anus.

An oroantral fistula (OAF) or oroantral communication (OAC) is an opening between the oral cavity and the maxillary sinus. If left untreated, these openings may cause chronic maxillary sinusitis. Although small defects (diameter <5 mm) may close spontaneously, larger communications require surgical intervention. Various studies have been conducted on OAC closure using a platelet-rich fibrin (PRF) membrane; most of these prior studies have involved simple direct application of PRF clots. This study introduces a new "double-barrier technique" using PRF for closure of an OAF involving sinus mucosal lifting and closure. The PRF material is inserted into the prepared maxillary sinus space, and the buccal advancement flap covers the oral side. This technique was successfully used to treat two patients with chronic OAF in the posterior maxillary region after implant removal or tooth extraction. The use of a PRF membrane in a double-barrier technique may have advantages in soft-tissue healing and could enable easy closure of chronic OAF with minimal trauma.
