Stump pyometra is defined as a reinfection or inflammation of uterine remnant after ovariohysterectomy. We surveyed four bitches which were serviced in the veterinary medical teaching hospital of Seoul National University. In this Paper we studied the method for diagnosis of stump pyometra by symptoms, blood tests, and ultrasound films. To detect the stump pyometra is difficult because clinical signs are verb similar to the normal pyometra. Especially symptoms could noticed be noticed even by their owner until dogs have a vaginal discharge. Blood test also were in normal range in each item except in the elevation of the number of while blood cells. We conclude ultrasonic observation add experimental laparotomy has a significant meaning to diagnosis the stump pyometra.

Purpose: Gastric stump cancer is defined as a cancer that develops in the stomach after a resection in cases of non-malignant or malignant gastric disease. The interval between the gastrectomy and the detection of gastric stump cancer must be over 5 years. Since duodenogastric reflux gastritis is a precancerous condition and one of the most important factors inducing gastric stump cancer, we compared the bile-acid content of gastric juice between gastric stump cancer patients and controls. Materials and Methods: To evaluate retrospectively the surgical treatment of patients with gastric stump cancer, we reviewed the cases histories of 1016 stomach cancer patients who had been operated on at the Department of General Surgery, Kosin University Gospel Hospital, between 1995 and 1998. The gastric juice was collected during the operations on the gastric stump cancer patients by using a needle puncture of the fundus of the stomach and during the endoscopic examinations of the control subjects. The samples were analyzed for various bile acids (gas chromatography/mass spectrometry). Results: The 6 gastric stump cancer cases accounted for $0.6\%$ of all gastric cancer patients; 5 patients were first operated on for a peptic ulcer and the remaining one for an adenocarcinoma of the stomach. All of the cases were men. The reconstruction method after the initial gastrectomy was a Billroth II in all cases. The sites of the gastric stump cancer were the anastomotic sitein 2 patients, the upper body in 2, the fundus in 1 and the cardia in 1. The operative methods were 3 total gastrectomies, 2 subtotal gastrectomies with Roux en Y anastomosis, and 1 partial gastrectomy with lymph node dissection and had a curative intention in all patients. All of the patients were still surviving at the time of this report. The gastric juices of 4 gastric stump patients showed significantly higher contents of cholic acid ($36.42{\mu}g/ml$) compared to the gastric juices of 35 control subjects ($36.42{\mu}g/ml$)(p$\leq0.0001$). Chenodeoxycholic acid and lithocholic acid were not significantly different. Conclusion: The gastric juice of gastric stump cancer patients contained a significantly higher cholic acid content. At the time of the initial gastrectomy, an operative method that prevents duodenogastric reflux may prevent or minimize the development of gastric stump cancer, and more aggressive surgical treatment may improve survival.

Cholecystectomy is the best method for treating gallstone diseases. However, 10%-30% of patients who undergo a cholecystectomy continue to complain of upper abdominal pain, dyspepsia, or jaundice-this is referred to as postcholecystectomy syndrome. Cystic duct stump stones are a troublesome cause of postcholecystectomy syndrome. Conventionally, surgery is mainly performed to remove cystic duct stump stones. However, repeated surgery can cause complications, such as postoperative bleeding, biliary injury, and wound infection. As an alternative method of surgery, endoscopic retrograde cholangiopancreatography is sometimes used to remove cystic duct stump stones, although the success rate is not high due to technical difficulties. Recently, peroral cholangioscopy, which can directly observe the bile duct, has been suggested as an alternative method. We report two cases in which a cystic duct stump stone was successfully removed via a single-operator cholangioscopy, after failure with an endoscopic retrograde cholangiopancreatography.

Purpose: We evaluated the clinical outcomes of the non-operative management of post-gastrectomy duodenal stump leakage in patients with gastric cancer. Materials and Methods: A total of 1,230 patients underwent gastrectomy at our institution between 2010 and 2014. Duodenal stump leakage was diagnosed in 19 patients (1.5%), and these patients were included in this study. The management options varied with patient condition; patients were managed conservatively, with a pigtail catheter drain, or by tube duodenostomy via a Foley catheter. The patients' clinical outcomes were analyzed. Results: Duodenal stump leakage was diagnosed in all 19 patients within a median of 10 days (range, 1~20 days). The conservative group comprised of 5 patients (26.3%), the pigtail catheter group of 11 patients (57.9%), and the Foley catheter group of 3 patients (15.8%). All 3 management modalities were successful; none of the patients needed further operative intervention. The median hospital stay was 18, 33, and 42 days, respectively. Conclusions: Non-operative management of duodenal stump leakage for selected groups of patients with gastric cancer was effective for control of intra-abdominal sepsis. This management modality can help obviate the need for surgical intervention.

This study was carried out to provide the technology of silvicultural practices and management for regeneration by sprouts in the oak forests distributed on the slope. A total of 1,451 stumps were examined for the following factors relative to the occurrence and growth of the sprouts: stump height & diameter; location & quantity and root collar diameter & height of arisen sprouts. The amount of sprouts deceased or increased as the stump diameter increased. However, it tended to increase with stump height. The difference in the stump height between direction of the upwards (DUS) and downward slopes (DDS) was occurred, because oak trees were felled lower based on direction of the upward for convenience of regeneration works on the slope. The number of sprouts was higher relatively in the stumps of DDS. The rate of arisen side and root sprouts was higher in the stumps of DDS and DUS, respectively. The stump height difference was found to affect the arisen part of sprouts. As a result of comparing the sprouts growth according to the arisen part, there was no difference in the stump of DUS, but the growth of side sprouts in the stump of DDS was higher than that of the root. In order to improve the quality of oak sprouts considering the distribution characteristics of the oak forests in South Korea, it is necessary to apply the silvicultural technique, making the cutting surface parallel with the slope to reduce the stump height difference, to suppress arising side sprouts.

Bronchial stump aspergillosis(BSA) is an infrequent disease developing on the bronchial stump after lobectomy with the silk as a suture material. The silk induces inflammatory reaction, granuloma formation, secondary infection of the bronchial stump and leads to BSA. If a patient complains of cough, hemoptysis, expectoration of suture material several months or years after lobectomy with the silk, BSA should be considered as one of causative mechanisms. Bronchoscopic identification of silk thread with aspergillosis and its removal is necessary. We report a case of BSA in a 59-year-old man with review of the literature.

The biomechanical interaction between the stump and the prosthetic socket is critically important to achieve close-to-normal ambulation. Many investigators suggested that the pressure changes during gait of transfemoral amputees are closely related to the prosthetic alignment, the socket shape, the stump size, and the residual muscle activity. The effects of the prosthetic alignment, the socket shape, and the stump size on the interface pressure were investigated previously. However, there is no report how the residual muscle activities in the transfemoral stump affect the socket interface pressure characteristics during gait. Since designs of socket fur lower limb amputees need to consider the socket interface pressure characteristics, the interface pressure patterns by the residual muscle activities during gait should be investigated. In this study, myoelectric signals (MES) and socket interface pressure in residual limb of transfemoral amputees were measured during the stance and swing phases of gait. For the purpose, specially designed quadrilateral sockets that MES electrodes could be instrumented were fabricated. A total of two transfemoral amputees were participated in the experiments. The measured temporal MES amplitude and interface pressure in knee flexor (biceps femoris) and extensor (rectus femoris) had significant correlations (P ＜ 0.05). Based on the test results, It was suggested that the residual muscle activity of transfemoral amputees stump is an important factor affecting socket pressure changes during walk.

Limb-salvage surgery has become more popular than amputation for the treatment of malignant bone tumor because no differences in local recurrence and the 5-year survival rate have been found. However for young patients with sarcoma, skeletal immaturity may be a contraindication to limb-salvage surgery due to the expected leg length discrepancy. If limb-sparing procedure should be impossible for skeletally immature patients, amputation has to be given first consideration. To minimize the functional difficulty from short amputation stump of above knee amputation, we performed lengthening of the amputation stump using ipsilateral tibia. One patient was lengthened 17cm using ipsilateral tibia and the other, 12cm. Two patients and their families were satisfied both clinically and psychologically.

Purpose: Laparoscopic gastrectomy is accepted as a standard treatment for patients with early gastric cancer in Korea, Japan, and China. However, duodenal stump leakage remains a fatal complication after gastrectomy. We conducted a prospective phase II study to evaluate the safety of the new technique of laparoscopic reinforcement suture (LARS) on the duodenal stump. Materials and Methods: The estimated number of patients required for this study was 100 for a period of 18 months. Inclusion criteria were histologically proven gastric adenocarcinoma treated with laparoscopic distal or total gastrectomy and Billroth II or Roux-en-Y reconstruction. The primary endpoint was the incidence of duodenal stump leakage within the first 30 postoperative days. The secondary endpoints were early postoperative outcomes until discharge. Results: One hundred patients were enrolled between February 2016 and March 2017. The study groups consisted of 65 male and 35 female patients with a mean age (years) of 62.3. Of these, 63 (63%) patients had comorbidities. The mean number of retrieved lymph nodes was 38. The mean operation time was 145 minutes including 7.8 minutes of mean LARS time. There was no occurrence of duodenal stump leakage. Thirteen complications occurred, with one case of reoperation for splenic artery rupture and one case of mortality. Conclusions: Based on the results of this prospective phase II study, LARS can be safely performed in a short operation period without development of duodenal stump leakage. A future randomized prospective controlled trial is required to confirm the surgical benefit of LARS compared to non-LARS.

Purpose: In case of the failed replantation, if the patients want to preserve the length of amputated stump, toe transfer is the ideal choice. However, reconstruction of these amputated stump with a free flap can be a useful method when the patients refuse sacrificing their toe. Our purpose of this study is to evaluate availability of functional results and patient satisfaction after this procedure. Materials and Methods: From March 2008 to February 2012, we reconstructed the amputated stump with free flap by patients demand. Eleven patients were included, medial plantar artery perforator flap in seven cases and great toe pulp flap in five cases. Follow-up range 12 to 24 months and we evaluate patient satisfaction by using a visual analogue scale (VAS; 1=unsatisfied, 5=excellent) and functional recovery by measuring the range of motion of remaining joint at 12 months after operation. Results: During follow-up period, all transferred free flaps survived and no major complications were noted. Range of motion of remaining joint appeared satisfactory result ($15^{\circ}$ to $100^{\circ}$). The VAS patient satisfaction score for aesthetic were five in six patients, four in four patients, and three in one patient. Conclusion: In case of the failed digital replantation, if patient refuse toe transfer, it could be useful method to reconstruction with the free flap to preserving maximal length of amputated stump.
