We present an overview of indications, procedures, considerations, and controversies in the surgical therapy of IBD.

Risk factors for lymph node metastasis and evaluation of reasonable surgery for early gastric cancer

AIM: To give the evidence for rationalizing surgical therapy for early gastric cancer with different lymph node status. METHODS: A series of 322 early gastric cancer patients who underwent gastrectomy with more than 15 lymph nodes retrieved were reviewed in this study. The rate of lymph node metastasis was calculated. Univariate and multivariate analyses were performed to evaluate the independent factors for predicting lymph node metastasis. RESULTS: No metastasis was detected in No.5, 6 lymph nodes (LN) during proximal gastric cancer total gastrectomy, and in No.10, 11p, 11d during for combined resection of spleen and splenic artery and in No.15 LN during combined resection of transverse colon mesentery. No.11p, 12a, 14v LN were proved negative for metastasis. The global metastastic rate was 14.6% for LN, 5.9% for mucosa, and 22.4% for submucosa carcinoma, respectively. The metastasis in group Ⅱ?was almost limited in No.7, 8a LN. Multivariate analysis identified that the depth of invasion, histological type and lymphatic invasion were independent risk factors for LN metastasis. No metastasis from distal cancer (≤ 1.0 cm in diameter) was detected in group Ⅱ?LN. The metastasis rate increased significantly when the diameter exceeded 3.0 cm. All tumors (≤ 1.0 cm in diameter) with LN metastasis and mucosa invasion showed a depressed macroscopic type, and all protruded carcinomas were > 3.0 cm in diameter. CONCLUSION: Segmental/subtotal gastrectomy plus D1/D1 + No.7 should be performed for carcinoma (≤ 1.0 cm in diameter, protruded type and mucosa invasion).Subtotal gastrectomy plus D2 or D1 + No.7, 8a, 9 is the most rational operation, whereas No.11p, 12a, 14v lymphadenectomy should not be recommended routinely for poorly differentiated and depressed type of submucosa carcinoma (> 3.0 cm in diameter). Total gastrectomy should not be performed in proximal, so does combined resection or D2+/D3 lymphadenectomy.

Clinical investigation of surgery for intermittent exotropia

Objective： To investigate the time and postoperative binocular vision of strabismus surgery for children with intermittent exotropia （X（T））. Methods： A retrospective investigation was conducted in 80 child patients with intermittent exotropia. Pre- and postoperative angles of deviation fixating at near （33 cm） and distant targets （6 m） were measured with the prolonged alternate cover testing. The binocular function was assessed with synoptophore. Twenty-one patients took the postoperative synoptophore exercise. Results： （1） A week after surgery, 96.2% of the 80 patients had binocular normotopia, while a year after surgery, 91.3% of the 80 patients had binocular normotopia; （2） Preoperatively, 58 patients had near stereoacuity, while postoperatively, 72 patients achieved near stereoacuity （P〈0.05）; （3） Preoperatively, 64 patients had Grade Ⅰ for the synoptophore evaluation and postoperatively, 76 patients achieved Grade Ⅰ. Meanwhile, 55 patients had Grade Ⅱ preoperatively and 72 achieved Grade Ⅱ postoperatively. For Grade Ⅲ, there were 49 patients preoperatively and 64 patients postoperatively （P〈0.05）; （4） Patients of 5-8 years old had a significantly better recovery rate of binocular vision than those of 9-18 years old （P〈0.05）; （5） Patients taking postoperative synoptophore exercise had a better binocular vision than those taking no exercise （P〈0.05）. Conclusions： （1） Strabismus surgery can help to preserve or restore the binocular vision for intermittent exotropia; （2） Receiving the surgery at young ages may develop better postoperative binocular vision; （3） The postoperative synoptophore exercise can help to restore the binocular vision.

Anal transition zone in the surgical management of ulcerative colitis

Preservation of the anal transition zone has long been a significant source of controversy in the surgical management of ulcerative colitis.The two techniques for restorative proctocolectomy and ileal pouch anal anastomosis(RPC IPAA) in common practice are a stapled anastomosis and a handsewn anastomosis;these techniques differ in the amount of remaining rectal mucosa and therefore the presence of the anal transition zone following surgery.Each technique has advantages and disadvantages in long-term functional outcomes,operative and postoperative complications,and risk of neoplasia.Therefore,we propose a selective approach to performing a stapled RPC IPAA based on the presence of dysplasia in the preoperative endoscopic evaluation.

Surgical Treatment of Intralobar Pulmonary Sequestration

Objective To evaluate the clinical features,diagnosis,treatment,and outcome of intralobar pulmonary sequestration (ILS). Methods Patients who were diagnosed with ILS in our hospital between January 1988 and January 2009 were retrospectively reviewed. We recorded the clinical symptoms,imaging findings,operative technique,complications,and outcome of these patients. Results Forty-seven patients (25 men and 22 women) with an average age of 32.3 years were enrolled. Forty-two patients had symptoms including cough and hemoptysis. Chest X-ray,computed tomography (CT),magnetic resonance imaging (MRI),and angiography were performed. Thoracotomy was performed in 45 patients,while thoracoscopy was performed in 2 patients. Lobectomy was the most common treatment procedure. Massive bleeding developed in 2 patients due to injury of aberrant supplying artery intraoperatively,1 patient had atrial fibrillation,1 patient had thrombosis of upper extremity postoperatively. All patients were confirmed the diagnosis pathologically,4 accompanied with bronchogenic cyst,15 with bronchiectasis,8 with infection,2 with aspergilloma,and 1 with carcinoid. No late complications occurred. Conclusions ILS is rare,surgery is recommended because some patients may have potential severe complications. Contrast enhanced CT and three-dimensional reconstruction is the best diagnostic method. Both thoracotomy and thoracoscopy are appropriate for the selected candidates.

Percutaneous nephrolithotomy in pediatric age group:Assessment of effectiveness and complications

Management of kidney stone disease in pediatric population is a challenging condition in urology practice. While the incidence of kidney stone is increasing in those group, technological innovations have conrtibuted to the development of minimally invasive treatment of urinary stone disease such as mini-percutenous nephrolitotomy(mini-PCNL), micro-PCNL, ultra mini-PCNL. In this review we tried to evaluate the effect of new teratment techniques on pediatric kidney stones.

Is intra-operative cholangiography necessary during laparoscopic cholecystectomy? A multicentre rural experience from a developing world country

AIM: To evaluate the feasibility and safety of performing laparoscopic cholecystectomy (LC) in nonteaching rural hospitals of a developing country without intra-operative cholangiography (IOC). To evaluate the possibility of reduction of costs and hospital stay for patients undergoing LC.METHODS: A prospective analysis of patients with symptomatic benign diseases of gall bladder undergoing LC in three non-teaching rural hospitals of Kashmir Valley from Jan 2001 to Jan 2007. The cohort represented a sample of patients requiring LC, aged 13 to 78 (mean 47.2) years. Main outcome parameters included mortality, complications, re-operation, conversion to open procedure without resorting to IOC, reduction in costs borne by the hospital, and the duration of hospital stay.RESULTS: Twelve hundred and sixty-seven patients (976 females/291 males) underwent laparoscopic cholecystectomy. Twenty-three cases were converted to open procedures; 12 patients developed port site infection, nobody died because of the procedure. One patient had common bile duct (CBD) injury, 4 patients had biliary leak, and 4 patients had subcutaneous emphysema. One cholecystohepatic duct was detected and managed intraoperatively, 1 patient had retained CBD stones, while 1 patient had retained cystic duct stones. Incidental gallbladder malignancy was detected in 2 cases. No long-term complications were detected up to now.CONCLUSION: LC can be performed safely even in non-teaching rural hospitals of a developing country provided proper equipment is available and the surgeons and other team members are well trained in the procedure. It is stressed that IOC is not essential to prevent biliary tract injuries and missed CBD stones. The costs to the patient and the hospital can be minimized by using reusable instruments, intracorporeal sutures, and condoms instead of titanium clips and endobags.

Double-balloon enteroscopy reliably directs surgical intervention for patients with small intestinal bleeding

AIM: To evaluate preoperative double-balloon enteroscopy for determining bleeding lesions of small intestine, thus directing selective surgical intervention. METHODS: We retrospectively reviewed 56 patients who underwent double-balloon enteroscopy to localize intestinal bleeding prior to surgical intervention, and compared enteroscopic findings with those of intraoperation to determine the accuracy of enteroscopy in identifying and localizing the sites of small intestinal bleeding. RESULTS: Double-balloon enteroscopy was performed in all 56 patients in a 30-mo period. A possible site of blood loss was identified in 54 (96%) patients. Enteroscopy provided accurate localization of the bleeding in 53 (95%) of 56 patients, but failed to disclose the cause of bleeding in 4 (7%). There was one case with negative intraoperative finding (2%). Resection of the affected bowel was carried out except one patient who experienced rebleeding after operation. Gastrointestinal stromal tumor (GIST) was most frequently diagnosed (55%). CONCLUSION: Double-balloon enteroscopy is a safe, reliable modality for determining bleeding lesion of small intestine. This technique can be used to direct selective surgical intervention.

Analysis of the Long-term Effect of Intraoperative Radiotherapy (IORT) for Non-Small Cell Lung Carcinoma (NSCLC)

OBJECTIVE To analyze the long-term effects of treatment with an op-eration + postoperative irradiation (A group) and an operation+intraoperative radiotherapy+postoperative irradiation (B group) in non-small cell lung cancer patients. METHODS Through a prospective randomized clinical trial, a total of 154 patients with non-small cell lung carcinoma were divided into two groups of 77 cases. Among the 154 cases, there were 134 squamous carcinomas, 17 adenocarcinomas and 3 adeno-squamous carcinomas. TNM staging: there were 17 in StageⅠ, 76 in Stage Ⅱ and 61 in Stage Ⅲ. A dosage of 15～25 Gy IORT, energy 9～16 MeV electrons, was delivered to the tumors. The doses given were 40～60 Gy postoperation. RESULTS The local control rates in A and B groups were 49.4% and 62.3% respectively (P<0.05). The survivals at 3, 5 and 7 years for group A were 40.3%, 27.3%, and 5.2% and for group B 44.2%, 28.6% and 6.5% (P>0.05). There were 16 deaths from radiotherapy complications, with 2 cases in group A and 14 in group B. CONCLUSION IORT+postoperative irradiation can enhance the local control rate of non-small cell lung cancer patients and reduce the recurrent rates, but it can not improve long-term survival.

Novel biomarkers of acute kidney injury: Evaluation and evidence in urologic surgery

atients undergoing urologic surgery are at risk of acute kidney injury （AKI） and consequently long-term deterioration in renal function. AKI is further associated with signifcantly higher odds of perioperative complications, prolonged hospital stay, higher mortality and costs. Therefore, better awareness and detection of AKI, as well as identifcation of AKI determinants in the urological surgery setting is warranted to pre-empt and mitigate further deterioration of renal function in patients at special risk. New consensus criteria provide precise definitions of diagnosis and description of the severity of AKI. However, they rely on serum creatinine （SCr）, which is known to be an inaccurate marker of early changes in renal function. Therefore, several newurinary and serum biomarkers promise to address the gap associated with the use of SCr. Novel biomarkers may complement SCr measurement or most likely improve the diagnostic accuracy of AKI when used in combinations. However, novel biomarkers have to prove their clinical applicability, accuracy, and cost effectiveness prior to implementation into clinical practice. Most preferably, novel biomarkers should help to positively improve a patient’s long-term renal functional outcomes. The purpose of this review is to discuss currently available biomarkers and to review their clinical evidence within urologic surgery settings.

Acupuncture for Treating Postoperative Enteroparalysis

Postoperative enteroparalysis refers to dysfunction of the intestinal tract after abdominal surgery, which is manifested by abdominal distension, failure of aerofluxus from the anus etc.

Safety control strategy for vertebral lamina milling task

Vertebral lamina milling task is one of the high-risk operations in spinal surgeries. The operation is to remove part of vertebral lamina and release the pressure on the spinal nerve. Because many important vessels and nerves are under the vertebral lamina, any incorrect operation may cause irreparable damage to patients. To improve the safety of lamina milling task, a fuzzy force control strategy is proposed in this paper. Primary experiments have been conducted on bone samples from different animals. The results show that, with the fuzzy force control strategy, the bone milling system can recognize all surgery states and halt the tool at the proper location, achieving satisfactory surgery performance.

Surgical treatment of anal stenosis

Anal stenosis is a rare but serious complication of anorectal surgery, most commonly seen after hemorrhoidectomy. Anal stenosis represents a technical challenge in terms of surgical management. A Medline search of studies relevant to the management of anal stenosis was undertaken. The etiology, pathophysiology and classification of anal stenosis were reviewed. An overview of surgical and non-surgical therapeutic options was developed. Ninety percent of anal stenosis is caused by overzealous hemorrhoidectomy. Treatment, both medical and surgical, should be modulated based on stenosis severity. Mild stenosis can be managed conservatively with stool softeners or fiber supplements. Sphincterotomy may be quite adequate for a patient with a mild degree of narrowing. For more severe stenosis, a formal anoplasty should be performed to treat the loss of anal canal tissue. Anal stenosis may be anatomic or functional. Anal stricture is most often a preventable complication. Many techniques have been used for the treatment of anal stenosis with variable healing rates. It is extremely difficult to interpret the results of the various anoplastic procedures described in the literature as prospective trials have not been performed. However, almost any approach will at least improve patient symptoms.

Application of posterior Moss-Miami transpedicular system for the treatment of adolescent idiopathic scoliosis

Objective： To determine the effectiveness of posterior Moss-Miami transpedicular system for the treatment of adolescent idiopathic scoliosis in 24 patients with a 2-year minimum follow-up. Methods： 24 patients who underwent operations between September 2002 and November 2003 were evaluated for curve correction, spinal balance, and complications. Age at surgery averaged 13.8 years （range from 10 to 20）. The spinal deformities were evaluated by Cobb method with anteroposterior and lateral bending radiographs. All patients were right thoracic curves. Posterior instrumentation （Moss-Miami transpedicular system） was used. The transpedicular screws were placed between T2 and L2. All the patients were assessed both clinically and radiographically. Follow-up averaged 2.8 years. Results： There was an average correction of 72% of the primary curve （pre-operation standing average 54 degrees （range from 40 to 67 degrees）, post-operation average 15.2 degrees （range from 2 to 27 degrees）, at last examination average 16.1 degrees （range from 2 to 30 degrees）. Infection and neurological complications were not noted. No major complications were observed. Conclusions： Frontal and sagittal thoracic curve correction of thoracic scoliosis can be satisfactorily obtained using Moss Miami transpedicular instrumentation. It seems that control of the three columns of the spine by the transpedicular screws offers sufficient apical translation and coronal realignment.

A new combined therapy to 15 patients with multiple organ failure in abdominal surgery

AIMS We report 15 cases of abdominal-surgical multiple organ failure(MOF)treated successfully by a new combined therapy four high doses in volume and one support“FHDOS”short period high doses in large volume anJsodaminum;short period high doses in large volume dexamethasonum;high doses in large volume of dis- infectant antibiotics;high doses in large volume of abdominal cav- ity washing liquor and support of nutrition metabolism.The mortal- ity rate and cost of MOF were decreased.It is simple,practical and effective. METHODS The study group consisted of 15 patients(10 wom- en,5 men;average age,42.7)who were hospitalized in our hospital.All patients were given“FHDOS”:short period high in large volume Anisodaminum:intravenous injection 40 mg once; another 40rag may be added 30 minutes later according to condition.The total amount may reach 120-240 mg a day,or,in- travenous injection 40 mg every 15 minutes until condition being under control.Short period high doses in large volume Dexamethasonum:intravenous injection 100-200 mg once;this remedy may be continued for 1-3 days;the amount also may de- crease according to condition.High doses in large volume of dis- infectant Antibiotics:select and use antibiotics according to clini- cal condition,inference of Gram's stain;it is necessary to re- peatedly culture bacteria in many parts,and then,to make ad- justment according to culture result and drug-resistance,and to prevent carefully the dual infections from occurring.High doses in large volume of abdominal cavity washing liquor:generally adopt- ing physiological saline 6000o8000ml in washing abdominal cavity. “One support”means full support of nutrition metabolism. RESULTS All the patients in this group survive well after the rescue without any complication. CONCLUSIONS MOF should be prevented,if possible,by stopping or controlling the injury,removing as much necrotic tis- sue as possible,improving blood flow and oxygen consumption, supporting metabolism,and preventing infection or treating it ear- ly and adequately.“FHDOS”is a combined therapy and plays a key role in treating MOF.

Surgical salvage therapy of anal cancer

AIM:To evaluate the results of salvage resection in the management of persistent or locally recurrent anal canal cancer.METHODS: Details of all patients with anal canal cancer treated from 1978 to 1994 at Cancer Hospital of Chinese Academy of Medical Sciences (CAMS) were reviewed retrospectively.Sixteen patients who presented with persistent or locally recurrent anal canal cancer received salvage surgery. Before surgery all of the patients had received radiotherapy alone as their primary treatments.RESULTS:Of the 16 patients, 14 received salvage abdominoperineal resection (APR) and two had transanal local excision. There were no deaths attributable to operation.Delayed healing of the perineal wound occurred in eight patients. Complications unrelated to the perineal wound were found in five patients. The median follow-up time was 120 (range 5-245) months after salvage surgery. Nine patients died of disease progression, with a median survival time of 16 (range 5-27) months. Six patients had a long-term survival.CONCLUSION:Salvage resection after radiotherapy can yield a long-time survival in selected patients with anal canal cancer. However it offers little hope to patients with T4 and/or N2-3 tumors.
