Recovery After Emergency Laparotomy: a Prospective Observational Feasibility Study

Observational feasibility study using Patient Reported Outcomes (PRO) to assess quality of life and 'return to normal life' up to 1 year following emergency laparotomy

Preoperative Exercise for Patients Undergoing Complex Cancer Surgery

Treatment for people with cancer of the lung or the oesophagus (food-pipe) often involves surgery. This surgery is complex and there is a high risk that patients will develop severe complications afterwards, leading to a longer hospital stay and higher hospital costs, and impacting greatly on recovery and quality of life. If patients' lungs and heart can be optimised before surgery, then recovery may be improved. While fitness can be improved by exercise, the lead-in time to surgery following a cancer diagnosis is often very short, and research is needed to examine what types of exercise might be most effective at increasing fitness over a short period. This project will investigate if high intensity interval training (HIIT) can increase fitness levels in people scheduled for surgery for cancer of the oesophagus or the lungs. HIIT alternates between periods of high intensity exercise, cycling on a stationary bike, followed by a period of more relaxed exercise. This approach is known to improve fitness but has not previously been investigated in patients awaiting complex cancer surgery. Groups will be compared for changes in pre-surgery fitness levels, any complications they may experience after surgery, general physical recovery after surgery and the cost of care after surgery. The investigators anticipate that patients who undergo HIIT before surgery will have less complications and better recovery after surgery, a significantly improved quality of life, and lower costs of care.

Effects of Restrictive Fluid Strategy on Postoperative Oliguric Pancreatic Surgery Patients

Reduced urinary output is a common postoperative issue for patients going through major surgery such as pancreatic surgery. Commonly this is treated by increasing fluid administration to the patients and sometimes also diuretics. However, overloading patients with fluid also have several risks and known complications. Studies have also shown that a short period of decreased urinary output in the postoperative period do not have an increased incidence of acute renal failure. The aim of our study is to investigate the difference in renal function and postoperative complications associated with fluid overload on these patients that are randomized to either receiving a fluid bolus directly when urinary output decreases or to await for a maximum of four hours to see if urinary output increases spontaneously.

Use of Melatonin for Preventing POCD in Transurethral Prostate Resection Under Spinal Anesthesia

This study aims to evaluate the possible effect of melatonin on prevention of cognitive dysfunction in the postoperative period of elderly patients undergoing transurethral resection of the prostate (TURP) under spinal anesthesia

The Effect of Preoperative Assessment Clinic on Prognosis and Economic Results of Patients With Coexisting Disease.

To assess the effect of preoperative assessment clinic on prognosis and economic results of patients with coexisting diseases, the investigators designed a prospective cohort study. The investigators will recruit 250 patients preparing to undergo a selective epigastrium surgery with coexisting medical diseases which need an anesthetic consultation. The patients will be randomly assigned into two groups. The intervention group will be seen in the preoperative clinic before hospitalization, while the control group will get anesthetic consultation after hospitalization without clinic service. No additional interventions will be given during and after surgery. The length of stay, hospitalization expense, postoperative complication rate and mortality rate of the two groups will be compared. The investigator assume that consultation in preoperative assessment clinic will improve the prognosis and decrease the hospitalization expenses.

Comparative Study of Antiperistaltic vs Isoperistaltic Billroth II + Braun Anastomosis for Postoperative Reflux

Postoperative gastroesophageal reflux is one of the most common complications of distal gastrectomy. With more attention paid on it by surgeons, several new operation methods have been practised. Among all these, distal gastrctomy with Billroth II + Braun anastomosis was reported to be an useful method to decrease postoperative reflux rate. Meanwhile, the direction of anastomotic peristalsis has also been reported to affect the anastomosis and thus make difference in reflux rate. We design this study to investigate the potential effect and the superiority of antiperistaltic vs isoperistaltic Billroth II + Braun reconstruction in distal gastrectomy.

Comparative Study of Medial-to-Lateral Approach vs Dorsal and Medial Hybrid Approach in Laparoscopic Right Hemicolectomy

To standardize the surgery for advanced right hemi colon cancer with laparoscopy and investigate whether dorsal and medial hybrid approach could improve disease-free survival in patients with right colon cancer, compared with traditional medial-to-lateral approach in laparoscopic righ hemicolectomy.

Clinical Value of Left Colic Artery in Laparoscopic Radical Rectectomy

Colorectal cancer is one of the most common tumors in Asia. According to the recent research, surgical procedure could provide more treatment benefit in rectal cancer. Therefore, it was consider that important to standardized and improved the surgical procedure for rectal cancer. With the development of anatomical technique, minimally surgery with laparoscopy had become the trend for surgical treatment. There were several studies has been done to evaluate the safety and feasibility of laparoscopic surgery. In order to achieve better surgical outcome and reduce operative complications, the investigators design stratified randomization, double blinded, muti - center clinical trail to investigate the value of left colic artery in laparoscopic radical rectectomy.

Standardization of Laparoscopic Surgery for Right Hemi Colon Cancer (SLRC)

To standardize the surgery for advanced right hemi colon cancer with laparoscopy and investigate whether extended lymphadenectomy (CME) could improve disease-free survival in patients with right colon cancer, compared with D3 radical operation in laparoscopic colectomy.
