Purpose: Laparoscopic gastrectomy in obese patients has been investigated in several studies, but its feasibility has rarely been examined in morbidly obese patients, such as in those with a body mass index (BMI) of ${\geq}30kg/m^2$. The present study aimed to evaluate the technical feasibility and safety of laparoscopic gastrectomy in morbidly obese patients with gastric cancer. Materials and Methods: A total of 1,512 gastric cancer patients who underwent laparoscopic distal gastrectomy (LDG) were divided into three groups: normal (BMI< $25kg/m^2$, n=996), obese (BMI $25{\sim}30kg/m^2$, n=471), and morbidly obese ($BMI{\geq}30kg/m^2$, n=45). Short-term surgical outcomes, including the course of hospitalization and postoperative complications, were compared between the three groups. Results: The morbidly obese group had a significantly longer operating time (240 minutes vs. 204 minutes, P=0.010) than the normal group, but no significant differences were found between the groups with respect to intraoperative blood loss or other complications. In the morbidly obese group, the postoperative morbidity and mortality rates were 13.3% and 0%, respectively, and the mean length of hospital stay was 8.2 days, which were not significantly different from those in the normal group. Subgroup analysis showed that postoperative complication rates were not high in morbidly obese patients, independent of the type of anastomosis technique used and level of lymph node dissection. Conclusions: LDG is technically feasible and safe in morbidly obese patients with a BMI of ${\geq}30kg/m^2$ and early gastric carcinoma. Except for a longer operating time, LDG might represent a reasonable treatment option in these patients.
Recently, the incidence of pressure sore has been increased, due to increased number of patients with central nervous system injuries after traffic and industrial accidents or with long term loss of consciousness due to drug intoxication. The management of sacral pressure sore has been improved through the development of myocutaneous flap. However, sacrifice of the deep muscle cause some problems such as intraoperative bleeding, functional disabilities of donor site and further limitation of reconstruction for recurrent pressure sores in paraplegic patients. The development of perforator-based island skin flap introduce a new treatment modality for sacral pressure sores. We used perforator-based island skin flap in 15 cases with reasonable result from January 1998 to February 2000. This flap has a many advantages such as no significant sacrifice of the gluteus maximus muscle, wide rotation arc, reliable blood flow of the perforator, short elevation time for the flap, and no post-operative hindrance to walking in patients who are not paraplegic. There was no significant complication without significant sequelae and donor sites could be repaired primarily.
Objective: To compare the clinical efficacy of concurrent chemoradiotherapy, neoadjuvant chemotherapy, and intracavity brachytherapy in comprehensive treatment for young patients with stage Ib2 cervical cancer. Methods: One hundred and twelve young patients with stage Ib2 cervical cancer were enrolled retrospectively in our hospital from January 2003 to June 2005. They were categorized into three groups according to preoperative regimens, including the concurrent chemoradiotherapy group (Group 1, n=38), the neoadjuvant chemotherapy (Group 2, n=49), and the intracavity brachytherapy group (Group 3, n=25). Radical hysterectomy was performed following these regimens. Chemotherapy and radiotherapy were given according to pelvic lymph node metastasis, deep cervical stromal invasion, intravascular cancer emboli, histological grading, vaginal stump and positive surgical margin. Results: The cancer disappearance and superficial muscle invasion rates were statistically significantly better in the concurrent chemoradiotherapy group than in the other two groups (P<0.01). No statistically significant difference was noted in the deep muscle invasion rate, surgical time and intraoperative blood loss among three groups, but significantly more postoperative complications occurred in the concurrent chemoradiotherapy group. The 2-year pelvic recurrence was statistically significantly lower in the concurrent chemoradiotherapy group compared to other two groups, while the 5-year survival was higher. Conclusion: Concurrent chemoradiotherapy is efficacious for young patients with stage Ib2 cervical cancer.

Objective : The lateral extracavitary approach(LECA) to the thoracolumbar spine is known as one of procedure which allows not only direct vision of pathologic lesion, but also ventral decompression, and dorsal fixation of the spine through the same incision. However, some drawbacks of LECA, including the technically- demanding, time-consuming, unfamiliar surgical anatomy and excessive blood loss, make surgeons to hesitate to use this approach. This study is to provide the surgical anatomy of LECA using cadavers, for detailed informations when LECA is considered for the surgery. Methods : We performed the 10 cadaveric studies, 7 male and 3 female, and careful dissection was carried out on right side of thoracolumbar region, except one for thoracic region. The photographs with micro-lens were taken to depict the close-up findings and for demonstrating detailed anatomy. Results : The photographs and hand-drawings demonstrated the relationships among the musculature, segmental vessels and nerve roots seen during each dissection plane. The lateral branches of dorsal rami of spinal nerve and the transverse process were confirmed to be the most important landmark of this approach. Conclusion : We concluded that detailed anatomical findings for LECA through this step-by-step dissection would be useful during operative intervention to reduce the intraoperative complications in LECA.
Objective : The purpose of this study was to introduce our surgical experiences of scoliosis and to evaluate the effectiveness of anterior correction and fusion in adolescent idiopathic scoliosis (AIS). Methods : Between August 2004 and August 2007, four patients with AIS were treated with anterior segmental fusion and fixation at our hospital. Mean follow-up period was 9 (6-12) months. The average age was 14.0 (13-15) years. According to Lenke classification, three patients showed Lenke 1 curve and one patient with Lenke 5 curve. Single rod instrumentation was performed in one patient, dual rod instrumentation in one patient and combined rod instrumentation in two patients. Coronal Cobb measurements were performed on all curves in thoracic, thoracolumbar and, lumbar spine and the angle of hump was measured by a scoliometer pre- and postoperatively. Results : The average operative time was 394 minutes (255-525) with an average intraoperative blood loss of 1,225 ml (1,000-1,700). The mean period of hospital stay was 19.3 days and there was no complication related to the surgery. The mean Cobb angle was reduced from $43.3^{\circ}$ to $14.8^{\circ}$ (65.8% correction) postoperatively and the rib hump corrected less than $5^{\circ}$. All patients and their parents were satisfied with the deformity correction. Conclusion : Anterior spinal correction and fusion of AIS with Lenke 1 and 5 curve showed excellent deformity correction without any complications. In particular, we recommend anterior dual rod instrumentation because of mechanical stability, better control of kyphosis, and a higher fusion rate.
Purpose: Since a patient's obesity can affect the mortality and morbidity of the surgery, less drastic surgeries may have a major benefit for obese individuals. This study evaluated the feasibility of performing a totally laparoscopic distal gastrectomy, with intracorporeal anastomosis, in obese patients suffering from gastric cancer. Materials and Methods: This was a retrospective analysis of the 138 patients, who underwent a totally laparoscopic distal gastrectomy from April 2005 to March 2009, at the National Kyushu Cancer Center. The body mass index of 20 patients was ${\geq}25$, and in 118 patients, it was <25 kg/$m^2$. Results: The mean values of body mass index in the 2 groups were $27.3{\pm}2.2$ and $21.4{\pm}2.3$. Hypertension was significantly more frequent in the obese patients than in the non-obese patients. The intraoperative blood loss, duration of surgery, post-operative complication rate, post-operative hospital stay, and a number of retrieved lymph nodes were not significantly different between the two groups. Conclusions: Intracorporeal anastomosis seemed to have a benefit for obese individuals. Totally laparoscopic gastrectomy is, therefore, considered to be a safe and an effective modality for obese patients.

Purpose: The laparoscopic transhiatal approach (LA) for adenocarcinoma of the esophagogastric junction (AEJ) is advantageous since it allows better visualization of the surgical field than the open approach (OA). We compared the surgical outcomes of the 2 approaches. Materials and Methods: We analyzed 108 patients with AEJ who underwent transhiatal distal esophagectomy and gastrectomy with curative intent between 2003 and 2015. Surgical outcomes were reviewed using electronic medical records. Results: The LA and OA were performed in 37 and 71 patients, respectively. Compared to the OA, the LA was associated with significantly shorter duration of postoperative hospital stay (9 vs. 11 days, P=0.001), shorter proximal resection margins (3 vs. 7 mm, P=0.004), and extended operative times (240 vs. 191 min, P=0.001). No significant difference was observed between the LA and OA for intraoperative blood loss (100 vs. 100 mL, P=0.392) or surgical morbidity rate ($grade{\geq}II$) for complications (8.1% vs. 23.9%, P=0.080). Two cases of anastomotic leakage occurred in the OA group. The number of harvested lymph nodes was not significantly different between the LA and OA groups (54 vs. 51, P=0.889). The 5-year overall and 3-year relapse-free survival rates were 81.8% and 50.7% (P=0.024) and 77.3% and 46.4% (P=0.009) for the LA and OA groups, respectively. Multivariable analyses revealed no independent factors associated with overall survival. Conclusions: The LA is feasible and safe with short- and long-term oncologic outcomes similar to those of the OA.
Purpose: Intra-abdominal infection is a common postoperative complication of laparoscopic pylorus-preserving gastrectomies (PPGs). Many studies have reported that intra-abdominal infectious complications after gastrectomy adversely affect patient survival outcomes. To prevent gastric fluid leakage into the abdominal cavity, we developed a novel anastomosis method in which the stomach lumen is not opened (termed the non-opened clean end-to-end anastomosis method [NoCEAM]) and evaluated its feasibility. Materials and Methods: Subsequent to lymphadenectomy, the oral and anal resection lines were sutured using an intraoperative endoscope. After closing the stomach circumferentially with clips, the specimen was rolled outward like a "donut." We resected the specimen circumferentially using a linear stapler, and anastomosis was completed simultaneously. We examined the feasibility of this procedure ex vivo, using three porcine stomachs, and in vivo, using one pig. Subsequently, we applied the procedure to 13 consecutive patients with middle-third early gastric cancer utilizing laparotomic, laparoscopic, and robotic PPG. Results: NoCEAM was completed in all porcine models and human cases. In the human cases, the mean operation time (±standard deviation) was 279±51 minutes, and mean blood loss volume was 22±45 mL. The mean number of linear staples used was 5.06±0.76. None of the patients had complications, and all were discharged on the eighth postoperative. The serum total protein, serum albumin, and hemoglobin levels did not change significantly after surgery. Conclusions: NoCEAM is feasible and safe for performing totally laparoscopic or robotic PPG. It may reduce postoperative complications, such as intra-abdominal infections.
Backgrounds/Aims: Central pancreatectomy (CP) is associated with a higher rate of postoperative pancreatic fistula (POPF), and it is less preferred over distal pancreatectomy (DP). We compared the short- and long-term outcomes between CP and DP for low-grade pancreatic neck and body tumors. Methods: This was a propensity score-matched case-control study of patients who underwent either CP or DP for low-grade pancreatic neck and body tumors from 2003 to 2020 in a tertiary care unit in southern India. Patients with a tumor >10 cm or a distal residual stump length of <4 cm were excluded. Demographics, clinical profile, intraoperative and postoperative parameters, and the long-term postoperative outcomes for exocrine and endocrine insufficiency, weight gain, and the 36-Item Short Form Survey (SF-36) quality of life questionnaire were compared. Results: Eighty-eight patients (CP: n=37 [cases], DP: n=51 [control]) were included in the unmatched group after excluding 21 patients (meeting exclusion criteria). After matching, both groups had 37 patients. The clinical and demographic profiles were comparable between the two groups. Blood loss and POPF rates were significantly higher in the CP group. However, Clavien-Dindo grades of complications were similar between the two groups (p = 0.27). At a median follow-up of 38 months (range = 187 months), exocrine sufficiency was similar between the two groups. Endocrine sufficiency, weight gain, SF-36 pain control score, and general health score were significantly better in the CP group. Conclusions: Despite equivalent clinically significant morbidities, long-term outcomes are better after CP compared to DP in low-grade pancreatic body tumors.

Background: The maintenance of antiplatelet therapy increases the risk of bleeding during lung cancer surgery. Conversely, the perioperative interruption of antiplatelet therapy may result in serious thrombotic complications. This study aimed to investigate the safety of continuing antiplatelet therapy in the context of lung cancer surgery. Methods: We retrospectively reviewed a cohort of 498 elderly patients who underwent surgery for lung cancer. These patients were categorized into 2 groups: group N, which did not receive antiplatelet therapy, and group A, which did. Group A was subsequently subdivided into group Am, where antiplatelet therapy was maintained, and group Ai, where antiplatelet therapy was interrupted. We compared the incidence of bleeding-related and thrombotic complications across the 3 groups. Results: There were 387 patients in group N and 101 patients in group A (Ai: 70, Am: 31). No significant differences were found in intraoperative blood loss, thoracotomy conversion rates, transfusion requirements, volume of chest tube drainage, or reoperation rates for bleeding control between groups N and A or between groups Am and Ai. The duration of hospital stay was longer for group A compared to group N (7 days vs. 6 days, p=0.005), but there was no significant difference between groups Ai and Am. The incidence of cardiovascular or cerebrovascular complications did not differ significantly between groups Ai and Am. However, group Ai included a severe case of in-hospital ST-elevation myocardial infarction. Conclusion: The maintenance of antiplatelet therapy was found to be safe in terms of perioperative bleeding and thrombotic complications in elderly lung cancer surgery patients.
