Sialolithiasis is the most common disease caused by calculi in a salivary gland and its duct. The pain and swelling of salivary gland is a chief complaint of patients presenting. Most salivary gland calculi occur in the submandibular gland, but can also occur in the parotid gland and the sublingual gland. One giant sialolith is rarely reported, while the several cases of one or multiple sialolith in the submandibular gland have reported in the literatures. In this case, we have removed the sialolith in which perforated mouth floor along Wharton's duct and report it.

An 18-year-old woman with annular pancreas and duodenal duplication presented with recurrent acute pancreatitis and underwent a resection of duodenal duplication. However, the patient experienced recurrent abdominal pain after resection. Abdominal computed tomography and magnetic resonance imaging showed a dilatation of the peripheral pancreatic duct and stenosis and malformation of both the Wirsung's and Santorini's duct due to multiple stones. The modified puestow procedure was performed. The main pancreatic ducts in the body and tail were opened, and the intrapancreatic common bile duct was preserved. A Roux-en-Y pancreatico-jejunostomy was performed for reconstructing the pancreaticobiliary system after removing the ductal protein plug. The patient experienced no abdominal pain, no significant elevation of the serum amylase and lipase levels, and no stone formation during the 2 years of follow-up. This procedure is considered to be beneficial for pediatric patients with chronic pancreatitis due to annular pancreas and duodenal duplication.

Sialolithiasis, the most common salivary gland pathology, is caused by calculi in the gland itself and its duct. While patients with small sialoliths can undergo conservative treatment, those with standard-size or larger sialoliths require sialolithotomy. In the present case study, we removed two sialoliths located beneath the mucosa in the posterior and anterior regions of Wharton's duct, respectively. For the posterior calculus, we performed sialolithotomy via an intra-oral approach; thereafter, the small anterior calculus near the duct orifice was removed by hydraulic power. This method has not previously been reported. There were no complications either during the operation or postoperatively, and the salivary function of the gland remained normal.

Objectives: This study examined the case of a patient with recurrent salivary duct carcinoma and hepatic metastasis. Methods: The patient was treated with Casodex/Nolvadex from January 25^th 2021 onward with doses of bicalutamide (150 mg/day) and tamoxifen (10 mg/day) every four weeks. Simultaneously, the patient was treated with Korean medicine. The tumor size was measured using computed tomography (CT). Adverse events were evaluated according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0. Results: Following the four-month treatment, the extent of the proximal portion of hepatic metastasis decreased, and discomfort and physical activity gradually improved. Conclusions: The results suggest that combined chemotherapy and Korean medicine may help to reduce tumor size and improve quality of life.

A thyroglossal duct cyst (TGDC) is the most common congenital anomaly of the neck. However, carcinoma arising from TGDC is extremely rare. We report 2 cases of TGDC carcinoma. In the first case, a 21-year-old male patient complained of an anterior cervical mass; computed tomography (CT) and sonography revealed cystic mass that was suspected to be a TGDC. Sistrunk operation was performed. Papillary carcinoma was confirmed in pathologic examination. Additionally, he underwent total thyroidectomy and central neck dissection. After radioactive iodine ablation (RAI) was performed. In the second case, a 28-year-old male patient visited our out-patient department complaining of submental mass. He had already been diagnosed TGDC carcinoma 13 years ago and had undergone Sistrunk operation and total thyroidectomy. Malignancy was confirmed using fine-needle aspiration; thus, lateral neck dissection was performed and following this, he underwent RAI. Till date, no evidence of recurrence has been observed in these patients.

Laparoscopic cholecystectomy is of one the most common general surgical operations performed today. Concomitant choledocholithiasis occurs in roughly 10-20% of patients with symptomatic gallstones. Laparoscopic bile duct exploration (LBDE) offers a single-stage minimally-invasive solution to the management of choledocholithiasis. LBDE may be performed either via the transcystic route or via laparoscopic choledochotomy. A number of strategies to improve success are available to the surgeon to help in the problem of complicated choledocholithiasis, these range from simple maneuvers to the use of laser or mechanical lithotriptors. With the advances in laparoscopic surgery, it is also possible to handle complex surgical conditions such as Mirizzi syndrome or recurrent pyogenic cholangitis laparoscopically, even though these have yet to be accepted as standard of care. Following laparoscopic choledochotomy, options for closure include: primary closure, closure over a T-tube, and closure over an endobiliary stent. T-tube placement has been associated with increased operating time and hospital length of stay compared to primary closure, with no significant differences in morbidity. Based on the available literature, LBDE appears comparable to ERCP with regards to procedural efficacy and morbidity. LBDE remains relevant to the general surgeon and is best viewed as being complementary to endoscopic therapy in the management of choledocholithiasis.

The Sialolithiasis is one of the most common disease that is found in the submandibular gland and they can be usually observed in the extra glandular area. As the lumen of Wharton's duct is larger and more expandable than that of Stensen's duct, the symptom of them is initially painless. As increasing their size, the sign and symptom are pain and sudden enlargement of gland. It can be observed with clinical exam and the scintigraphy. After removal of sialoliths, the majority of them can get the recovery of function. Our department performed the transoral sialolithotomy and the extraoral sialoadenectomy for three patients of sialolithiasis and all of them showed no complication after operation.

As the lumen of Wharton's duct is larger and more expandable than that of Stensen's duct, the symptom of them is initially painless. Obstruction of salivary secretion by a sialolith can result in sudden swelling and pain, as well as infection of the gland. It can be observed with clinical exam and the scintigraphy. After removal of sialoliths, the majority of them can get the recovery of function. Our department performed the transoral sialolithotomy. One of three cases was recurred sialolithiasis with sialadenitis and was performed by the re-sialolithotomy and extraoral sialoadenectomy.

It is common to design the duct branches where to supply the required air flow for individual room in residential apartment house. And TAB process is applied to control the designed air volume with adjusting volume dampers and/or supply diffusers after fully installing the ventilation system. This process has been resulted increasing the initial cost for the residential ventilation system because of man-hour and accessories such as volume control damper or diffuser. However it is difficult to adjust the air volume adequately in small air duct branches in residential ventilation system. The purpose of this study is to figure out the performance of Multidrop chamber coupling system for the residential ventilation system.

Choledochal cyst is a dilation that encloses the intrahepatic or both extra- and intrahepatic portions of the biliary ducts. Postnatally, ultrasonography is the initial diagnostic modality of choice, allowing for precise measurements of intra- or extrahepatic duct dilatation and identification of stones and sludge. Symptoms depend on the age at presentation. Common bile duct malformations should be considered as a differential diagnosis of a cystic mass regardless of the cyst's size or patient's age, especially in children presenting with abdominal pain, jaundice, and palpable mass. To the best of our knowledge, we report the largest choledochal cyst in infancy.
