Background: To present the experience of management of leaks following laparoscopic sleeve gastrectomy for morbid obesity in Show-Chwan memorial Hospital. Patients and Methods: Laparoscopic sleeve gastrectomy is considered one of the surgical options for morbid obesity. It is effective, with an average loss of 50% of excessive weight after 2 years of follow-up. The first laparoscopic sleeve gastrectomy was performed in January 2010 at Show-Chwan Memorial Hospital. Between January 2010 and October 2016, 300 patients underwent laparoscopic sleeve gastrectomy for morbid obesity. There were 218 women and 82 men with a mean age of 35.4 years. Preoperative mean body weight was 90.7 kg and mean body mass index (BMI) was 37.3 kg/m2. Results: Mean operative time was 85 minutes. Mean hospital stay was 3.5 days. There were no deaths. There were 5 complications (1.67%): leakage of gastroesophageal junction. One patient was conservative treatment. Two patients were successfully treated by self-expandable metallic stents and the other two patients were treated with esophageal stent also, but failed and further treated with fibrin (Histoacryl) injection to the leak site to try to seal the fistula. In six months follow-up, mean BMI decreased from 37.3 to 29.2 kg/m2, and mean excess weight loss reached 42.8%. Conclusions: Laparoscopic sleeve gastrectomy is a beneficial operation in terms of excessive weight loss, with acceptably complications. The leaks were located in gastroesophageal junction mostly, and could be resolved with esophageal stent. For the patients failed in esophageal stents, we try Histoacryl injection to improve it.

Purpose: Perforated peptic ulcer is an emergency condition. Laparoscopic ulcer repair is a feasible and safe procedure. The aim of this study was to research the efficacy of laparoscopic repair of peptic ulcer and to discuss the causes of conversion from laparoscopy to laparotomy. Methods: We collected 34 patients with perforated peptic ulcer underwent laparoscopic surgery from October 2003 to October 2008. Thirty four patients with perforated peptic ulcer underwent laparoscopic intervention and 6 cases were converted to laparotomy. The demographics, laboratory data, perioperative data, morbidity and mortality were compared. Results: In demographics of two groups, there were no significant differences in sex, age, location, and mean duration of symptoms of acute abdominal pain. However, there were significant differences in median size of perforation, mean duration of history of peptic ulcer related pain, and the experiences of surgeon. There were no significant differences in the laboratory data and perioperative data of two groups. In morbidity and mortality of two groups, there were no significant differences in leakage, wound infection, intra-abdominal abscess, ileus, urinary tract infection, pneumonia, and mortality, but there was significant difference in overall morbidity in two groups. Conclusions: Laparoscopic repair of perforated peptic ulcer is safe and could be used in routine clinical practice. However, patients with larger perforations (>10 mm), longer duration of history peptic ulcer related pain (>2 years), and learning curve of surgeon could be associated with conversion rate. It is associated with higher morbidity in patients with conversion from laparoscopy to laparotomy.

Background: Ten-millimeter ports are often used in laparoscopic surgery. It could be difficult to close the ports sites, especially in obese patients. We described a new method to close ten-millimeter port-site wounds, effective and easily to perform. Methods: Forty cases of laparoscopic bariatric surgery were performed from April 2010 to September 2011 at IRCAD Taiwan. Among them, 30 patients received trocar hole closed with SURGICEL&reg Original Hemostat and the other 10 patients received trocar hole closed with autologous fat. The results were recorded. Results: In group of SURGICEL&reg Original Hemostat, includes 21 female and 9 male, age range from 18 to 54 with average 39.5 years. Average BMI is 42.4 (range from 32.6 to 55). The operations include 27 cases of laparoscopic sleeve gastrectomy, 2 cases of laparoscopic gastric bypass, and 1 case of laparoscopic mini-bypass. Group of autologous fat includes 3 female and 7 male, age range from 20 to 49 with average 38.6 years. Average BMI is 39 (range from 32.8 to 64.5). The operations include 9 cases of laparoscopic sleeve gastrectomy, and 1 case of laparoscopic mini-bypass. No complications of trocar wound including infection, hematoma, and hernia were found for a mean follow-up of 6 months. Conclusions: For obese patients, closure of port sites can be difficult. We described a method of closing 10-mm port-sites wounds, which are easy, effective, and not required any special instruments.

Breast cancer treatment is multimodality. Prognosis prediction models depend on the tumor characteristics, neoplastic stage, intrinsic subtypes of oncogenes, molecular targets and dominant driving pathway. Immunohistochemical scores 4 (IHC4) is one of the most common and simplest prognostic models for breast cancer. IHC4 consists of four standard breast cancer biomarkers, including estrogen receptor (ER), progesterone receptor (PR), Ki-67 proliferative factor and human epidermal growth factor receptor 2 (Her-2/＂neu＂). The IHC4 scoring method was created mathematically and correlated with other genetic prediction models for breast cancer statistically. We have published Cdk5 and p35 proteins overexpression in some cancers including breast cancer. We inspected the expression of Cdk5 and p35 proteins to the IHC4 model in statistics. To date, several interesting proteins and genes are under investigation for linkage to the documented pathway in breast cancer. Even our results did not satisfy our expectation. We build a research model for the interesting proteins from bench to bed. In practice, the method is as simple as the purpose of the IHC4 method itself.

Laparoscopic surgery for choledocholithiasis is still evolving. Only a few reports of single-incision laparoscopic common bile duct exploration (LCBDE) have been published. One hundred and one consecutive patients underwent single-incision LCBDE (SILCBDE) by one surgeon with straight instruments during a 42-month period. Choledochotomies were performed on 61 patients (60.4%). The success rate of intrahepatic duct exploration was 68.0% (17/25) for patients undergoing transcystic choledochoscopic bile duct explorations following longitudinal cystic ductotomies. The ductal clearance rate was 100%. Eighteen procedures (17.8%) were converted, including one open surgery. Nineteen patients (18.8%) experienced 26 episodes of complications; the majority (19 episodes) were classified as Clavien–Dindo grade I. Excluding those patients with Mirizzi syndrome (McSherry type II), multivariate logistic regressions showed that patients who were older or had complicated cholecystitis had higher procedure conversion rates and that higher modified APACHE II scores, higher white blood cell counts, and longer operative times were independent risk factors for complications. Based on operative times, 20 successful SILCBDEs were needed to get through the learning phase. A higher transcystic approach rate (46.5 vs. 8.3%; P

Background. Endoscopy-assisted breast surgery performed through minimal axillary and/or periareolar incisions is a viable option for patients with breast cancer. In this study, we report the preliminary results of patients with breast cancer who underwent endoscopy-assisted total mastectomy (EATM) followed immediately by pedicled transverse abdominis musculocutaneous (TRAM) flap reconstruction. Methods. Patients in this study comprised women with breast cancer who received EATM and pedicled TRAM flap reconstruction. Clinicopathologic characteristics, type of surgery, complications, and rate of recurrence were recorded. The cosmetic outcomes were evaluated objectively by the surgeons and subjectively by the patients at 3-month postoperative follow-up. Results. A total of 48 patients underwent 49 EATM procedures followed by pedicled TRAM flap reconstruction. Of them, 79.6% underwent endoscopic-assisted nipple-sparing mastectomy and 20.4% received endoscopic-assisted skin-sparing mastectomy. The types of cancer among these patients included ductal carcinoma in situ in 34.7%, stage I cancer in 36.7%, stage II cancer in 24.5%, and stage IIIa cancer in 4.1% patients. Mean tumor size was 2.1 ± 1.4 cm. There were no cases of flap failure. Partial nipple areolar complex ischemia/necrosis occurred in 4 (10.3%) patients; however, all cases resolved after conservative treatment. In the aesthetic outcome evaluation, EATM + TRAM were associated with 89.8% good, 8.2% fair, and 2% unsatisfactory result. No local recurrence was observed during the follow-up period. Conclusion. EATM followed immediately by pedicled TRAM flap reconstruction is a safe procedure and results in good cosmetic outcome in women with early-stage breast cancer.

Summary Invasive pulmonary aspergillosis (IPA) is a rare, life-threatening infection in liver transplant recipients. Here, we report a case of primary cutaneous aspergillosis with following lung involvement in a liver transplant recipient. The survival rate of patients with IPA can be increased by early diagnosis using high-resolution computed tomography, a combination of two effective antifungal agents, temporal reduction or cessation of immunosuppressive drugs, and surgical intervention with video-assisted thoracoscopic surgery.

Diverticular disease is very common in Western societies. However, there is a trend towards reducing indications for the surgical management of diverticulitis. Minimally invasive surgery offers many potential advantages to patients in the treatment of diverticulitis and may optimise surgical indications. A systematic literature review of minimally invasive techniques was carried out for the treatment of diverticulitis. The following techniques were reviewed: laparoscopic, single-port, natural orifice specimen extraction, natural orifice transluminal endoscopic surgery and laparoscopic lavage for the treatment of diverticulitis. In total, 2,050 minimally invasive cases were reviewed. Of all the different minimally invasive techniques published regarding the management of diverticular disease, laparoscopic surgery is the only technique that has undergone the rigours of randomised controlled trials. The documented benefits are less blood loss, less pain and analgesic requirements, a reduction in major complications, a reduction in the frequency of drain usage, a reduction in the duration of postoperative ileus and shorter hospital stay. However, operative time does appear to be longer. It has also been demonstrated that elective laparoscopic surgery results in improved quality of life and social functioning. Minimally invasive surgery for the treatment of diverticular disease appears feasible and safe. The result of future randomised trials will more clearly define the role each minimally invasive technique will play in the future.

Purpose: Chilaiditi’s syndrome is the hepatodiaphragmatic interposition of the colon. Its diagnosis poses challenge to clinicians, and misdiagnosis may results in unnecessary exploratory laparotomy being performed. The purpose of this study was to report our experience in diagnosis, management, and clinical outcome of patients with Chilaiditi’s syndrome. Methods: Nine cases of Chilaiditi’s syndrome from April 2005 to January 2007 at one institute. The clinical characteristic, imaging studies, management and results were recorded. Results: Six patients presented with abdominal distension (2 patients with abdominal pain; 5 patients with constipation), while Chilaiditi’s syndrome in the other three patients were found incidentally. All patients underwent chest X-ray. The Chilaiditi’s sign could be detected in seven patients; while the other two patients presented with no specific finding. Abdominal plain films (KUB) were all reviewed. Most of the patients (n = 8) showed ileus and one patient showed no specific finding. Impacted stool could be detected in five of nine patients. Abdominal ultrasound was performed in two patients. Gallstones were detected in one of them while the other revealed no specific finding. Six of nine patients underwent CT of abdomen, one of them revealed bowel loops in bilateral subphrenic space. One patient underwent subtotal colectomy because of volvulus of sigmoid colon. Five patients were treated with laxative and enema successfully and had been remained asymptomaticcally for a mean follow-up of 6.6 months. The other three cases were under observation. Conclusions: Presence of haustral folds of bowel loops may help us in diagnosing Chilaiditi’s syndrome. The left lateral decubitus abdominal plain film can also help to differentiate between pneumoperitoneum to Chilaiditi’s sign. Most of the cases with Chilaiditi’s syndrome can be resolved with conservative treatment and surgical intervention was reserved for patients with sign of systemic toxicity or peritonitis.

Summary Background/Introduction The da Vinci robotic surgical system was developed to overcome the limitations of conventional laparoscopic surgery. Purpose/Aims We retrospectively reviewed our experience in performing robot-assisted laparoscopic hernioplasty (RALH) during robot-assisted laparoscopic radical prostatectomy (RALP) based on a single surgeon’s experience. Methods From December 2005 to December 2008, a total of 100 patients with prostate cancer underwent RALPs by a single surgeon. We retrospectively reviewed the medical records and analyzed the patients’ ages, body mass indices (BMI), levels of prostate-specific antigen, the biopsy percentage, the Gleason score and clinical stages of the biopsy specimens in 11 patients who had a RALP and a RALH simultaneously. The diagnosis of preoperative inguinal hernia (IH) was based on the results of a clinical physical examination, abdominal computed tomography or magnetic resonance imaging. The postoperative IHs were detected by the appearance of a protruding mass in the inguinal area on coughing, which was noticed during a physical examination. The total operative time, blood loss, type of the hernia, postoperative hospital stay, and the incidence of an IH after a RALP were evaluated. Results Of the 100 patients, 89 (89%) received a RALP only, 11 underwent a RALP and a RALH simultaneously, 7% had a preoperative IH and 4% had a subclinical IH, which were found during operations. Three patients (3%) developed an IH during follow-up. There were no significant differences between the RALP group and RALP combined with the RALH group in terms of age, BMI, tumor stage, and operative time. Blood loss and the time required for urethrovesical anastomosis were significantly higher in the subclinical IH group than in the preoperative IH group. Conclusions The incidence of an IH after a RALP was 3% with a mean follow-up of 32.42 ± 11.76 months in this study. Subclinical IHs were relatively easier to notice during a RALP because of a high degree of pneumoperitoneum, the realistic 3D imaging and the steady view of the da Vinci robotic system. Thus, such a robotic procedure can be regarded to facilitate a more precise detection of occult IHs during a RALP, and it possibly decreases the incidence of IHs after a RALP.

To treat secondary hyperparathyroidism with subtotal parathyroidectomy or total parathyroidectomy with autotransplantation might cause the disease to recur because of growth of the parathyroid remnant or the autografts. The aim of the present study was to determinate an alternative surgical treatment for secondary hyperparathyroidism. Of 94 uremic patients, 44 (median age: 50.5 years; 33 women/11 men) were assigned to group A, patients who were not expected to receive kidney transplantation for various reasons and had total parathyroidectomy without autotransplantation; 50 (median age 46 years; 33 women/17 men) were assigned to group B, patients who had either total parathyroidectomy with autotransplantation or subtotal total parathyroidectomy with preservation of parathyroid tissue in situ. Parameters measured included demographics, perioperative and follow-up biochemistry tests, operative time, postoperative complications, length of hospital stay, patients’ compliance with the postoperative calcium and 1,25 dihydroxy-viatmin D supplementation regimen, symptom relief, and presence of recurrence. Mean operative times were 103 and 122 min (P = 0.007); postoperative complication rates were 18.2% and 12.0% (P = 0.563); mean hospital stays were 6 and 9 days (P = 0.259); adequate patient compliance with the postoperative calcium and 1,25 dihydroxy-viatmin D regimens were 84.1% and 78.0%, respectively (P = 0.6); symptom relief rates were 88.6% and 80.0% (P = 0.277). Recurrence rates over 60 months in group A and group B were 4.5% and 18.0%, resectively (P = 0.028 by Kaplan-Meier analysis). Because of the lower recurrent rate and shorter operative time, total parathyroidectomy without autotransplantation may be an option for treating patients with symptomatic secondary hyperparathyroidism who are not expected to receive kidney transplantation.

A review of the literature pertaining to percutaneous transhepatic cholangioscopic lithotomy (PTCSL) showed that more than 50% of reported patients had undergone earlier biliary surgery.A retrospective study investigated 74 patients undergoing initial PTCSL for hepatolithiasis who had undergone no prior biliary surgery or manipulation. The patients were followed for 1 to 23 years after PTCSL for effective evaluation of the procedure outcome.Complete clearance of hepatolithiasis was achieved for 61 (82%) patients. The incomplete clearance rate was higher for patients with intrahepatic duct stricture (11/37 [30%] vs 2/37 [5%]; p0.05), although it showed no relation to the actual lobar distribution of hepatolithiasis (left: 7/41 [17%] vs right: 2/11 [18%] vs bilateral: 4/22 [18%]; p0.05). The recurrence rate for hepatolithiasis also was higher for patients with intrahepatic duct stricture (18/26 [69%] vs 13/35 [37%]; p0.05), but the recurrence rate showed no relation to the lobar distribution of hepatolithiasis (left: 18/34 [53%] vs right: 4/9 [44%] vs bilateral: 9/18 [50%] p0.05) or the presence of gallbladder stones (5/12 [42%] vs 26/49 [53%]; p0.05). Patients showing the coexistence of retained or recurrent hepatolithiasis demonstrated a higher incidence of recurrent cholangitis (57% [13/23] vs 14% [7/51]; p0.01) or cholangiocarcinoma (17% [4/23]) vs 0% [0/51]; p0.01).The findings show that PTCSL is effective for treating primary hepatolithiasis, and that complete stone clearance is mandatory to diminish the sequelae of hepatolithiasis. Intrahepatic duct stricture was the main factor contributing to incomplete clearance and stone recurrence.

SummaryBackground: Stump appendicitis is a rare delayed complication of appendectomy. Several diseases present with right lower abdominal pain, and therefore it is occasionally difficult to make a differential diagnosis, especially in patients with a history of appendectomy. In this paper we present our experiences with acute appendicitis following an appendectomy. Patients and Method: We selected five cases from January 2002 to December 2010. The clinical characteristics, imaging studies, treatment, and outcome were recorded. Results: All patients presented with abdominal pain (4 patients with fever). The mean duration of onset was 2 days. All patients had a history of ruptured appendicitis (2 patients showed a combination with generalized peritonitis). The mean duration since the previous appendectomy was 7.54 years. 4 patients underwent an abdominal ultrasound, and all patients underwent abdominal computed tomography, showing again a ruptured appendicitis. 4 of 5 patients had a stump appendicitis. All of the patients showed a good prognosis following surgery. Conclusions: The stump following an appendectomy should be shortened as much as possible. However, sometimes recurrent appendicitis with perforation will develop in patients with complete resection of the appendix. Stump appendicitis is associated with a history of ruptured appendicitis.

AIM: The aim of this study was to evaluate the effectiveness of technetium-99m tetrofosmin (Tc-99m TF) single photon emission computed tomography (SPECT) of the neck and chest to detect metastatic lesions in papillary thyroid carcinoma (PTC) after near total thyroidectomy and radioiodine (I-131) treatment in patients who present with elevated serum human thyroglobulin (hTg) levels but negative I-131 whole body scan (WBS). MATERIALS AND METHODS: Twenty patients with PTC treated by near total thyroidectomy and I-131 treatments were included in this study. All 20 patients had negative I-131 WBS results and elevated hTg levels (hTg 2.0 μIU/ml) under thyroid-stimulating hormone (TSH) stimulation (TSH 30 μIU/ml). Nineteen of the 20 cases were confirmed to have metastases by operation/biopsy histopathological findings or clinical follow-up longer than 1 year by additional morphological imaging techniques. The remaining patient has been followed up closely and has been disease free for 10 months. Tc-99m TF SPECT was performed to detect metastatic lesions. RESULTS: Tc-99m TF SPECT demonstrated lesions in 11/19 patients; a sensitivity of 57.9%. Tc-99m TF SPECT failed to demonstrate lesions in eight patients including smaller lymph nodes and miliary lung metastases. CONCLUSIONS: We conclude that Tc-99m TF SPECT is a useful additional tool to detect metastatic lesions in PTC with elevated hTg but negative I-131 WBS. However, smaller lymph nodes and miliary lung metastases may be missed.

Neutrophilic leukocytosis above 50 × 109/l exclude leukemia, defines a leukemoid reaction (LR). It is associated with several diseases. Although it simulates leukemia, most of the causes are benign. Tumor-related LR is more common. It is associated with ranulocyte colony-stimulating factor (G-CSF) secreted by the tumor cells. A 38-year-old woman, presented with advanced breast cancer and leukocytosis (79.9 × 103/uL) was found. After completion of MRM, the condition of leukocytosis subsided. Two months later, tumor local relapse was found and white blood cells (WBC) rose again. After completion of wide excision, the condition of leukocytosis subsided again. We think this case was associated with leukemoid reaction.

Background Findings related to the influence of the −160C → A promoter polymorphism and haplotypes of the E-cadherin (CDH1) gene have not been consistent in previous studies regarding the risk for sporadic gastric cancer. Investigators in most previous studies detected those genotypes using restriction fragment length polymorphism analysis. Therefore, we conducted a case–control study to investigate the association of the CDH1 − 160C → A promoter polymorphism and haplotypes for cancer risk related to sporadic diffuse and intestinal gastric cancer by direct sequencing analysis. Methods We included 107 diffuse gastric cancer cases, 60 intestinal gastric cancer cases and 134 controls. The genotypic polymorphisms in the −160 promoter region, exons and intron–exon boundaries of CDH1 were detected by direct sequencing analysis. Genotype frequencies were compared. The CDH1 − 160C → A promoter polymorphism and four polymorphisms (48 + 6 T → C, 2076C → T, 2253C → T and 1937–13 T → C) were included in the haplotype analyses, which were estimated using the expectation–maximization algorithm. Results Compared to controls, the frequency of the −160A allele was significantly higher in diffuse gastric cancer cases (P = 0.005), but it was not significantly different in intestinal gastric cancer cases (P = 0.119). Two sets of three-marker haplotypes (−160C → A, 48 + 6 T → C, 2076C → T and −160C → A, 1937–13 T → C, 2253C → T) were associated with the risk of diffuse gastric cancer (P = 0.011 and P = 0.042, respectively). Conclusion Based on direct sequencing analysis, our findings suggest that the CDH1 − 160C → A promoter polymorphism and haplotypes play significant roles in cancer risk for sporadic diffuse gastric cancer, but not for intestinal gastric cancer, in a Taiwanese population.

BACKGROUND The prognosis of anaplastic thyroid carcinoma (ATC) has been dismal. The objective of this study was to identify prognostic factors in patients who had prolonged survival. METHODS Patients with ATC were identified from a computer database at a tertiary referral center. Univariate and multivariate analyses for survival differences were performed using the Kaplan–Meier log-rank statistic and the Cox proportional hazards model, respectively. RESULTS Of the 33 evaluable patients, median survival was 3.8 months. Median age was 69 years. Prior goiter was present in 6 patients (18%), and 6 (18%) had prior thyroid carcinoma. Median tumor size was 6 cm, and 12 (36%) had adjacent well-differentiated carcinoma. Of the 26 patients who underwent neck exploration, 8 patients were potentially cured and received postoperative chemotherapy and irradiation; 4 (50%) were surgically macroscopically free of disease, and 4 (50%) patients had minimal residual disease after total thyroidectomy and resection of tumor adherent to adjacent structures. Four of these 8 patients survived longer than 2 years; their 5-year survival estimate was 50%. Eighteen patients underwent palliative resection of neck disease, leaving macroscopic residual disease or distant metastases; postoperative adjuvant chemotherapy and irradiation were administered in 16 of these 18 patients. Seven patients were treated with only chemotherapy and irradiation. In patients treated with potentially curative resection, median survival was 43 months compared with 3 months with palliative resection (P =0.002); the median survival of 3.3 months with only chemotherapy and irradiation was no different than palliative resection (P =0.63). No association was found between survival and age, prior goiter, prior thyroid carcinoma, adjacent differentiated carcinoma, or tumor size. CONCLUSIONS Although the prognosis of most patients with ATC continues to be poor, complete resection of ATC combined with postoperative adjuvant chemotherapy and irradiation resulted in long-term survival, even with persistent minimal disease that remained on vital structures. An aggressive attempt at maximal tumor debulking followed by adjuvant therapy was found to be warranted in patients with localized ATC. Cancer 2001;91:2335–42. © 2001 American Cancer Society.

Background: Hepatic resection for multiple hepatocellular carcinomas (HCCs) involving both lobes of the liver is rarely recommended because of high operative risks and low radicality. Thus the justification of hepatic resection for bilobar multicentric HCC remains undefined. Methods: Two hundred eleven patients with HCC, who underwent curative hepatic resection, were studied retrospectively. The patients were divided into two groups. Group A consisted of 39 patients with bilobar (both sides of Cantlie's line) multicentric HCCs. Group B consisted of 172 patients with HCC with solitary or unilobar lesions. The backgrounds and resectional results of patients in groups A and B were compared. Results; Patients in group A usually required multiple separate liver resections and a longer operative time. However, the operative blood loss, amount of blood transfused, and operative morbidity and mortality rates were not significantly different. Patients in group A showed higher incidences of associated satellite nodules, microscopic vascular invasion, and a lack of capsules. The 6-year disease-free and actuarial survival rates of patients in groups A and B were 30.5% and 41.8% (p = 0.17) and 42.9% and 51.4% (p = 0.12), respectively. For patients in group A the presence of satellite nodules in any resected tumor was the only independent unfavorable feature that influenced the actuarial survival rate after multivariate analysis. Conclusions: Liver resection is justified for bilobar multicentric HCCs in selected patients, if the tumors can be totally resected. Postoperative adjuvant therapies should be considered when satellite nodules are present in any resected tumor. (Surgery 1998;123:270-7.)

Acute appendicitis is the most common etiology of the acute abdomen, generally requiring urgent surgical intervention. The lifetime incidence of acute appendicitis is approximate 7%. In 1886, Fitz described the natural course of appendicitis. He began advocating early appendectomy to prevent perforation with subsequent complications of sepsis, shock and potential mortality. In 1894 McBurney introduced the right lower quadrant incision to approach the appendix. The open appendectomy (OA) through a McBurney incision came into favour more than a century ago. It is a simple, safe, quick, and effective operation that can be performed by a general surgeon with the basic surgical instruments.

With the advances in laparoscopic instruments and surgical techniques, the use of laparoscopic appendectomy (LA) has been increasing rapidly in recent years. In this retrospective analysis, we aimed to determine the competitive edge of LA versus open appendectomy (OA) in different settings of disease complexity, gender, and age difference.A retrospective analysis of the patients diagnosed with acute appendicitis at Changhua and Chang-Bing Show-Chwan Memorial Hospitals from January 1, 2004 to December 31, 2009 was conducted. Trend and indication of OA and LA were recorded, combined with a comparison of medical costs, complication rates, wound infection rates, and hospital stays in different settings of disease complexity, gender, and age group.A total of 1366 appendicitis patients were enrolled, and the rate of LA use increased rapidly, from 8.1% in 2004 to 90.3% in 2009. The increased use of LA was seen in both the uncomplicated and complicated appendicitis patients and in both gender and age groups (pediatric, adult, and elderly). Compared with OA, LA was associated with a lower complication rate (9.5% versus 5.8%; P = .013), a lower wound infection rate (8.6% versus 4.2%; P = .001), and a shorter hospital stay (4.60 ± 3.64 versus 4.06 ± 1.84 days; P = .001), but a higher mean cost (32,670 ± 28,568 versus 37,567 ± 12,064 New Taiwan dollars). In the subgroup analysis, the patients with complicated appendicitis, female patients, and pediatric and elderly patients benefited from a reduced hospital stay. LA is about 15% more expensive than OA.LA is as safe and effective as OA in many settings of appendicitis and may be selectively advantageous in patients with complicated appendicitis and in elderly subgroups.

Background Hemobilia is a rare but lethal biliary tract complication. There are several causes of hemobilia which might be classified as traumatic or nontraumatic. Hemobilia caused by pseudoaneurysm might result from hepatobiliary surgery or percutaneous interventional hepatobiliary procedures. However, to our knowledge, there are no previous reports pertaining to hemobilia caused by hepatic pseudoaneurysm after T-tube choledochostomy. Case presentation A 65-year-old male was admitted to our hospital because of acute calculous cholecystitis and cholangitis. He underwent cholecystectomy, choledocholithotomy via a right upper quadrant laparotomy and a temporary T-tube choledochostomy was created. However, on the 19th day after operation, he suffered from sudden onset of hematemesis and massive fresh blood drainage from the T-tube choledochostomy. Imaging studies confirmed the diagnosis of pseudoaneurysm associated hemobilia. The probable association of T-tube choledochostomy with pseudoaneurysm and hemobilia is also demonstrated. He underwent emergent selective microcoils emobolization to occlude the feeding artery of the pseudoaneurysm. Conclusions Pseudoaneurysm associated hemobilia may occur after T-tube choledochostomy. This case also highlights the importance that hemobilia should be highly suspected in a patient presenting with jaundice, right upper quadrant abdominal pain and upper gastrointestinal bleeding after liver or biliary surgery.

Acute appendicitis is the most common acute abdomen in general surgery. Show-Chwan Memorial Hospital began an AITS/IRCAD laparoscopic training program in late May 2008. In this retrospective analysis, we surveyed the impact of the AITS training program on surgeons’ preference for open appendectomy (OA) versus laparoscopic appendectomy (LA). From January 1, 2004 to July 31, 2009, patients diagnosed with acute appendicitis in Changhua Show-Chwan Memorial Hospital and Chang-Bing Show-Chwan Memorial Hospital were retrospectively analyzed. Demographic data, laboratory examinations, surgical methods, hospital stay, and complication rate data were collected and analyzed. The LA rate and effect of surgeons’ preference before and after AITS were compared. In all, 1,267 patients (58.2% male and 41.8% female; mean age, 36.6 years) were diagnosed with acute appendicitis during this period. Among them, 78.9% of patients had uncomplicated and 21.1% complicated appendicitis; 784 patients (61.9%) underwent OA, and 465 (36.7%) received LA. In 2004, only 8.1% of patients underwent LA, but the number increased rapidly to 90.4% in 2009 (P

Rupture of hepatocellular carcinoma (HCC) is a life-threatening complication. Peritoneal metastasis of HCC after spontaneous rupture was seldom noted. We report a case of intraperitoneal metastasis of HCC after spontaneous rupture. A previously asymptomatic 72-year-old man was admitted due to dull abdominal pain with abdominal fullness. He had a history of HCC rupture 10 mo ago and transarterial embolization was performed at that time. Abdominal computer tomography (CT) scan showed a huge peritoneal mass over the right upper quadrant area. Surgical resection was arranged and subsequent microscopic examination confirmed a diagnosis of moderately-differentiated HCC.

The patency of patch-enlarged (capsule-shaped) brachial arteries for long-term hemodialysis access was evaluated retrospectively. Twelve brachial arteries were patched with polytetrafluoroethylene (PTFE) grafts (standard wall thickness), making 1 x 2 cm aneurysms proximal to the elbow joints in 10 patients (six men with six patches, four women with six patches; patient age: 53 to 76 years, mean age +/- SD: 65.4 +/- 8.5 years) between September 2001 and April 2002. Ten patches were needled for each hemodialysis session as blood-drawing ports. The port's 1-year primary patency rate was 90%, 2-year patency was 70%, and 3-year patency was 70%. Two patches were needled in each hemodialysis session for dialyzed blood infusion access; both clotted within 1 year, with intact vessel continuity. Patch enlargement (capsule-shaped) of the brachial artery with a PTFE graft can be used as a long-term blood-drawing access in selected patients. This novel access may help patients with central vein stenosis or occlusion (which some patients had) and may help patients who have comorbid conditions such as chronic congestive heart failure or liver cirrhosis with ascites.

Gastric glomus tumors are rare submucosal lesions that typically occur in the fourth endosonographic layer. We describe a 69-year-old patient who presented with intermittent epigastric pain and in whom a submucosal tumor was encountered during upper gastrointestinal endoscopy. Endosonography revealed a heterogeneous, hypoechoic fourth-layer tumor. Power Doppler imaging revealed prominent intratumoral vascular signals demonstrating its hypervascular nature. A diagnosis of glomus tumor was made via histopathologic evaluation of the resected tumor. © 2007 Wiley Periodicals, Inc. J Clin Ultrasound, 2007

Background and Aims: The aim of this study was to determine the prevalence and risk factors of gallstone disease (GSD) in an adult population of Taiwan through a population-based screening study. Methods: A cross-sectional community study in a rural village of Taiwan was conducted in 3333 Chinese adults (aged ≥18 years) undergoing ultrasonography. A questionnaire on personal history was completed to ascertain whether the removed gallbladder contained stones in all cholecystectomized subjects, the dietary habits (vegetarian/non-vegetarian diet), the history of GSD in the participant’s first-degree relatives, the history of gastrointestinal surgery (vagotomy, gastrectomy for peptic ulcer disease, or ileal resection), parity, and use of oral contraceptives. The demographic characteristics and biochemical parameters were recorded Results: The overall prevalence of GSD was 5.0% (4.6% in men, 5.4% in women) with no significant sex differences (men/women: odds ratio [OR] 0.71, 95% confidence interval [CI] 0.50–1.01, P = 0.058). Logistic regression analysis showed that increasing age (men: 40–64 years, OR 7.38, 95% CI 2.59–21.01, P

Minimally invasive surgery has revolutionized the treatment of gastrointestinal tumors. Submucosal tumors of the stomach can be resected using laparoscopic techniques. We report here a case of ectopic pancreas tissue in the gastric wall that was removed using robotic-assisted laparoscopic resection. The patient was a 15-year-old female who presented with abdominal discomfort and tarry stools. Laboratory analysis showed iron deficiency anemia. Preoperative endoscopy revealed a submucosal lesion in the posterior wall of the gastric high body. Intraoperative upper endoscopy clearly located the lesion. A robotic-assisted laparoscopic wedge resection of the putative gastric submucosal tumor was performed. The pathology results showed an ectopic pancreas. The patient had an uneventful recovery and we believe that this is a valid treatment option for this benign condition.

Although serum leptin concentrations are reported by several studies to increase in patients with liver cirrhosis, the mechanisms underpinning this increase remain unclear. Circulating tumor necrosis factor alpha (TNF-alpha) concentrations are also recognized to increase in liver cirrhosis. Furthermore, TNF-alpha administration to rodents results in increased expression and secretion of leptin from adipose tissue in a manner dependent on type 1 TNF-alpha receptor (TNF-RI). The present study was undertaken to examine adipose leptin expression and to explore potential relationships between leptin expression and TNF-alpha in subjects with liver cirrhosis. Liver cirrhosis was induced in male Sprague-Dawley rats by dimethylnitrosamine (DMN) administration or by common bile duct ligation (BDL). Ad libitum and pair-fed animals constituted controls. Serum leptin and TNF-alpha concentrations were determined by immunoassay. Gene expression was determined by the reverse transcription-polymerase chain reaction, and protein levels were measured by Western blotting. Serum leptin values after adjustment of body fat mass in DMN-treated rats were significantly higher than in pair-fed or ad libitum groups. Leptin mRNA and protein levels in epididymal fat in DMN rats increased by 1.8-fold and 2.3-fold, respectively, as compared with ad libitum controls, and by 4-fold and 6-fold, respectively, as compared with the pair-fed group. Epididymal TNF-alpha and membranous TNF-RI (mTNF-RI) concentrations were both 2.3 times higher in DMN rats than in ad libitum controls but did not differ between ad libitum and pair-fed groups. Adipose leptin protein levels correlated directly with TNF-alpha and mTNF-RI concentrations in combined DMN, ad libitum, and pair-fed rats (r=0.64 and r=0.49, respectively; P

In an attempt to obviate the necessity for hospitalisation, the ablative dose of 131I in the treatment of thyroid cancer is divided into two or three fractions at weekly intervals in some hospitals with no special bed for 131I treatment. Thyroid stunning has been observed in patients receiving a 131I dose between 74 and 370 MBq (2–10 mCi). However, the influence of 131I uptake after administration of a higher dose, such as 1,110–1,850 MBq of 131I, has never been reported. In this study, we evaluated the degree of reduction in 131I uptake after patients received 1,480 MBq of 131I and evaluated the clinical value of fractionated ablative doses of 131I. Thirty-five patients with functional thyroid cancer received a total of 4,440 MBq (120 mCi) of 131I which was divided into three fractions administered at weekly intervals. In all patients two 131I whole-body scans were performed. The first scan was performed directly prior to the second dose of 131I (7 days after the first administration of 131I), and the second scan was performed 7 days after the second administration of 131I and directly prior to the third administration. Regions of interest including the neck and lungs were drawn to calculate the uptake of 131I in the thyroid remnant and possible cervical lymph node and lung metastases. The mean uptake of 131I was 2.73% 7 days after the first administration, and decreased significantly to 0.26% 7 days after the second administration. The mean decrease was as high as 80.7%. The decrease in 131I uptake was significant in all patients except the two with lung metastases. In the two patients with lung metastases, no definite evidence of decreased uptake was noted; the uptake of 131I in the lung metastases even increased on the second 131I image in one of these patients. After administration of 1,480 MBq of 131I, the decreased uptake was significant in all neck lesions but not in lung metastases. The use of fractionated ablative doses of 131I is not to be recommended in patients without lung metastases. However, the influence of fractionated ablative doses of 131I in patients with lung metastases is worthy of further study.

It remains difficult to pre-operatively differentiate follicular carcinoma and adenoma even under intraoperative investigations including histopathologic diagnosis of frozen sections.We retrospectively compared dual phase thallium (Tl-201) thyroid scan and fine-needle aspiration (FNA) cytology to detect follicular carcinoma in 12 patients with cold thyroid nodules. Fine-needle aspiration cytology results were assessed and categorized by experienced pathologists into benign, suspicious, and malignant. Dual phase Tl-201 thyroid scan including an early (10-min) image and a delayed (3-hour) image were acquired after 2 mCi (74 MBq) of Tl-201 was injected intravenously. Dual phase Tl-201 thyroid scan findings were visually interpreted as positive and negative results.Based on FNA cytologic interpretation criteria, three nodules were diagnosed as benign, five nodules were diagnosed as suspicious, and four nodules were diagnosed as malignant. However, based on dual phase Tl-201 thyroid scan interpretation criteria, all of the 12 nodules could accurately diagnose as malignant.We conclude that dual phase Tl-201 thyroid scan was more accurate in diagnosing follicular carcinoma when comparing with FNA cytology.

Low 24-hour thyroid uptake of I-131 (I-131 uptake) is a common finding that influences evaluation of the thyroid gland. Methods: We studied 20 female patients aged 16–82 years with low I-131 uptake. The following causes of reduced I-131 uptake were defined as (A) six cases with subacute thyroiditis, (B) seven cases with T4 suppression therapy, and (C) seven cases with iodinated pharmaceuticals use. Thirty-minute Tc-99m tetrofosmin thyroid scan was performed within 24 hours of the I-131 thyroid study. Results: The results were correlated with neck ultrasound, serum TSH and biopsy histopathological findings. Tc-99m tetrofosmin thyroid scans revealed 10 normal thyroids, five diffuse goiters, four multinodular goitres, and one solitary thyroid nodule. Conclusions: Our results suggest that Tc-99m tetrofosmin thyroid scans may provide additional information to diagnose thyroid pathology in patients with low 24-hour I-131 uptake.

We report a rare case of primary malignant mesothelioma of the greater omentum. To our knowledge, only one other such case has been described in the English literature. The patient was a 61-year-old Taiwanese woman without any history of exposure to asbestos, who presented with lower back pain. Abdominal sonography and computed tomography showed a 12 x 9 x 9-cm(3) mass occupying the lower abdomen. Laparotomy revealed a tumor in the greater omentum, invading the posterior wall of the uterus, without diffuse mesenteric thickening or multiple small nodules in the peritoneum. We performed en bloc resection of the mass, which involved omentectomy, hysterectomy, and bilateral salpingo-oophorectomy. Microscopically, the tumor cells were arranged in a tubulopapillary pattern lined by a single layer of uniform, cuboidal cells. A pattern of sclerotic stroma with irregular glandular elements was also recognized. Immunohistochemically, the tumor cells showed strong positivity for calretinin. The final pathologic diagnosis was malignant mesothelioma. The patient did not receive chemotherapy or radiotherapy, and has remained in good health without any evidence of recurrence for almost 3 years since her operation.

Background: Acute appendicitis is much more serious in the elderly, and early diagnosis is very important. However, the diagnosis of acute appendicitis in older patients is often difficult because these patients may present with atypical clinical manifestations. Methods: We conducted a prospective study to evaluate and compare the value of technetium 99m hexamethylpropyleneamine oxide (Tc 99m HMPAO) labeled white blood cell (WBC) abdominal scan and abdominal sonography in the diagnosis of acute appendicitis in older patients with an atypical clinical presentation. Forty-nine patients (age > 50 years) with acute abdominal pain and suspected appendicitis, but with atypical findings, were included in this study. Results: Twenty-seven patients received laparotomy for final surgical and pathologic diagnoses. The remaining 22 patients did not receive surgery and showed no evidence of appendicitis after at least 1 month of follow-up. Two patients had false-positive WBC scan findings and two patients had false-negative WBC scan findings. The overall sensitivity, specificity, and accuracy for WBC scans in diagnosing appendicitis were 92.0%, 91.7%, and 91.8%, respectively. The overall sensitivity, specificity, and accuracy for abdominal sonography in diagnosing appendicitis were 84.0%, 95.8%, and 89.8%, respectively. Conclusion: The Tc 99m HMPAO WBC scan provides a more sensitive and accurate method for diagnosing appendicitis in older patients with equivocal clinical examinations when compared with abdominal sonography.

Background. The purpose of this study was to retrospectively evaluate technetium 99m tetrofosmin (Tc-TF) uptake in parathyroid adenomas and compare the results with their expression of multidrug resistance-mediated 170-kDa P-glycoprotein (Pgp). Methods. Twenty patients with larger parathyroid adenomas (> 1.5 g) and the other 40 patients with smaller parathyroid adenomas (0.5-1.5 g) underwent early and delayed (10-minute and 2-hour) Tc-TF parathyroid imaging before operation. In this retrospective study, immunohistochemical analyses were performed on multiple nonconsecutive sections of the 40 parathyroid adenomas and 40 normal control specimens (20 normal parathyroid glands and 20 normal thyroid specimens) to detect Pgp expression. Results. The Tc-TF parathyroid image accurately localized 17 larger and 16 smaller parathyroid adenomas, but not the remaining 3 larger and 4 smaller adenomas. The 17 larger and 16 smaller parathyroid adenomas with significant Tc-TF uptake on the delayed 2-hour parathyroid images revealed negative Pgp expression, but the 3 larger and 4 smaller adenomas without significant Tc-TF uptake, as well as 20 normal parathyroid glands and 20 normal thyroid specimens, revealed positive Pgp expression. Conclusions. Not only the size of parathyroid adenomas, but Pgp expression also limited the sensitivity of Tc-TF parathyroid image to localize parathyroid adenomas before the operation.

Objective To investigate whether the increased homocysteine levels occur in the first 6 months postoperatively, when nutritional intake is the most inadequate and weight reduction is the most drastic. Patients and Methods Fasting glucose, insulin, lipoprotein, homocysteine, folic acid and vitamin B12 levels and oral glucose tolerance test (OGTT) were determined in 12 morbidly obese subjects (3 men and 9 women with a mean age of 31±3 years, mean±SEM) before, 6 and 12 months after banded gastroplasty. Results Gastroplasty resulted in significant weight loss, from 12±16 to 92±6 and 88±7 kgs, 6 and 12 months postoperatively (all p

Although patients with differentiated thyroid cancer (DTC) of follicular cell origin usually have an excellent prognosis, some patients die from progressive tumor. Numerous postoperative criteria have been used to predict prognosis in patients with DTC. The purpose of this investigation was to determine whether the TNM and metastases, age, completeness of resection, invasion, size (MACIS) classifications predicted survival time and why patients died from DTC. The extent of initial treatment and causes of death were also evaluated in these patients who died from thyroid cancer.Between 1965 and 1995, 102 of 1,224 patients with DTC treated at the University of California at San Francisco (UCSF) and UCSF/Mount Zion Medical Centers died from DTC. Risk factors including age at diagnosis, gender, histologic characteristics, TNM and MACIS classifications, the intervals among initial treatment, recurrence, and death, and the initial and subsequent treatments were documented in these 102 patients.Among the 102 patients who died of DTC 50% were men and 50% were women. The mean age of patients with DTC at diagnosis was 58 years at recurrence, 62 and 65 years at death. Thirty percent of these patients initially had unilateral thyroid operations and 70% had a bilateral operation. Tumors at presentation ranged from 0.6 to 13.0 cm (mean 4.4 cm); 46% of patients presented with late-stage tumors (TNM stage III, IV; MACIS score8). At presentation 46% of the patients had locally recurrent disease or regional metastases and 18% had distant metastases. Patients with persistent disease had a significantly shorter survival time than those with recurrent disease (p0.001). Both TNM and MACIS classifications were good predictors of survival time. Reoperations were performed in 51% of papillary, 26% of follicular, and 67% of Hürthle cell thyroid cancer patients. Fifty percent of patients with papillary thyroid cancer, 50% of patients with Hürthle cell thyroid cancer, and 11% of patients with follicular cell thyroid cancer died of locally advanced disease.As expected, patients with local or regional recurrence and those with TNM stage I or MACIS score6 survived longer than patients with distant metastasis and TNM stage III or IV, MACIS score6, but some patients thought to be at low risk (TNM stage I; MACIS6) also died from thyroid cancer.

Primary retroperitoneal mucinous cystadenomas (RMCs) are very rare and their biological behavior and histogenesis remain speculative. An accurate preoperative diagnosis of these tumors is difficult because no effective diagnostic measures have been established. We describe a 29-year-old woman with abdominal pain and a palpable mass. Computed tomography (CT) of the abdomen revealed a retroperi-toneal cystic mass which was resected successfully at laparotomy. Histopathological examination of the resected mass confirmed the diagnosis of RMC. There was no evidence of disease 2 years after surgery.

AIM: To retrospectively establish the diagnostic criteria of gallstone ileus on CT, and to prospectively apply these criteria to determine the diagnostic accuracy of CT to confirm or exclude gallstone ileus in patients who presented with acute small bowel obstruction (SBO). Another purpose was to ascertain whether the size of ectopic gallstones would affect treatment strategy. METHODS: Fourteen CT scans in cases of proved gallstone ileus were evaluated retrospectively by two radiologists for the presence or absence of previously reported CT findings to establish the diagnostic criteria. These criteria were applied in a prospective contrast enhanced CT study of 165 patients with acute SBO, which included those 14 cases of gallstone ileus. The hard copy images of 165 CT studies were reviewed by a different group of two radiologists but without previous knowledge of the patient’s final diagnosis. All CT data were further analyzed to determine the diagnostic accuracy of gallstone ileus when using CT in prospective evaluation of acute SBO. The size of ectopic gallstone on CT was correlated with the clinical course. RESULTS: The diagnostic criteria of gallstone ileus on CT were established retrospectively, which included: (1) SBO; (2) ectopic gallstone; either rim-calcified or total-calcified; (3) abnormal gall bladder with complete air collection, presence of air-fluid level, or fluid accumulation with irregular wall. Prospectively, CT confirmed the diagnosis in 13 cases of gallstone ileus with these three criteria. Only one false negative case could be identified. The remaining 151 patients are true negative cases and no false positive case could be disclosed. The overall sensitivity, specificity and accuracy of CT in diagnosing gallstone ileus were 93%, 100%; and 99%, respectively. Surgical exploration was performed in 13 patients of gallstone ileus with ectopic stones sized larger than 3 cm. One patient recovered uneventfully following conservative treatment with an ectopic stone sized 2 cm in the long axis. CONCLUSION: Contrast enhanced CT imaging offered crucial evidence not only for the diagnosis of gallstone ileus but also for decision making in management strategy.

Background Mucoceles resulting from cystadenomas of the appendix are uncommon. Although rare, rupture of the mucoceles can occur with or without causing any abdominal complaint. There are several reports associating colonic malignancy with cystadenomas of the appendix. Herein, we report an unusual and interesting case of right inguinal hernia associated with left colon cancer. Case presentation A case of ruptured mucocele resulting from cystadenoma of the appendix was presented as right inguinal hernia in a 70-year-old male. The patient underwent colonoscopy, x-ray, ultrasound and computed tomography. Localized pseudomyxoma peritonei associated with adenocarcinoma of the descending colon was diagnosed. The patient underwent segmental resection of the colon, appendectomy, debridement of pseudomyxoma and closure of the internal ring of right inguinal canal. He is free of symptoms in one year follow-up. Conclusion Synchronous colon cancer may occur in patients with appendiceal mucoceles. In such patients, the colon should be investigated and colonoscopy can be performed meticulously in cases of ruptured mucoceles and localized pseudomyxoma peritonei. Surgical intervention is the current choice of management.
