The impact of intraoperative microbreaks with exercises on surgeons: A multi-center cohort study.

Recent literature has demonstrated ergonomic risk to surgeons in the operating room. One method used in other industries to mitigate these ergonomic risks is the incorporation of microbreaks. Thus, intraoperative microbreaks with exercises in a non-crossover design were studied. Fifty-six attending surgeons from 4 Medical Centers volunteered first in a day of their regular surgeries and then second day where there were microbreaks with exercises that could be performed in the sterile field, answering questions after each case, without significantly increasing the duration of their surgeries. Surgeons self-reported improvement or no change in their mental focus (88%) and physical performance (100%) for the surgical day incorporating microbreaks with exercises. Discomfort in the shoulders was significantly reduced while distractions and flow impact was minimal. Eighty-seven percent of the surgeons wanted to incorporate the microbreaks with exercises into their OR routine. Intraoperative microbreaks with exercises may be a way to mitigate work-related musculoskeletal fatigue, pain and injury.

STARTING A LAPAROSCOPIC SURGERY PROGRAMME IN THE SECOND LARGEST TEACHING HOSPITAL IN GHANA.

BACKGROUND: Komfo Anokye Teaching Hospital (KATH) is the second largest hospital in Ghana. Two years have elapsed after performance of the first laparoscopic cholecystectomy. OBJECTIVES: To examine our experience and lessons learned. DESIGN: Retrospective review. SETTING: Komfo Anokye Teaching Hospital (KATH). SUBJECTS: We reviewed leadership support, the role of a surgeon champion, training of physician and OR staff, influence of surgeons from outside Ghana and equipment status. The results of laparoscopic cholecystectomies performed from 2010-2012 were compared with information available from open cholecystectomies over the same period. RESULTS: Evidence of leadership support included equipment purchase and invitation of outside experts yearly from 2008. A KATH surgeon champion was identified in 2010. A dedicated OR team received training and exhibited excellent ownership of equipment preparation. Since 2010, 25 laparoscopic cholecystectomies have been performed, 17 independently by a single surgeon. Average operative time was 1.41 hours and length of stay (LOS) 1.5 days. Conversion rate was 4.0% (1/25). Complication rate was 20.0% (5/25), none involving haemorrhage or injuries to bile ducts or bowel. Median patient satisfaction score was 5 on a scale of 1-5 where 5 is most satisfied. Complication rates and hospital stay were lower than for open cholecystectomy (20.0% vs 34.5%, p > 0.05 and 1.5 days vs 6.6 days, p < 0.001 respectively). Operative times were on average 27 min onger for laparoscopic cholecystectomy (p < 0.01). CONCLUSION: Laparoscopic cholecystectomy at KATH has become a reality with less complications rates, shorter LOS, and trends towards improved patient satisfaction. Expanding laparoscopic surgery in Ghana requires its inclusion into residency training programmes and public education about its benefits for both patients and physicians.

Natural orifice transluminal endoscopic surgery for intra-abdominal emergency conditions.

BACKGROUND: Patient benefits from natural orifice transluminal endoscopic surgery (NOTES) are of interest in acute-care surgery. This review provides an overview of the historical development of NOTES procedures, and addresses their current uses and limitations for intra-abdominal emergency conditions. METHODS: A PubMed search was carried out for articles describing NOTES approaches for appendicectomy, percutaneous gastrostomy, hollow viscus perforation and pancreatic necrosectomy. Pertinent articles were reviewed and data on available outcomes synthesized. RESULTS: Emergency conditions in surgery tax the patient's cardiovascular and respiratory systems, and fluid and electrolyte balance. The operative intervention itself leads to an inflammatory response and blood loss, thus adding to the physiological stress. NOTES provides a minimally invasive alternative access to the peritoneal cavity, avoiding abdominal wall incisions. A clear advantage to the patient is evident with the implementation of an endoscopic approach to deal with inadvertently displaced percutaneous endoscopic gastrostomy tubes and perforated gastroduodenal ulcer. The NOTES approach appears less invasive for patients with infected pancreatic necrosis, in whom it allows surgical debridement and avoidance of open necrosectomy. Transvaginal appendicectomy is the second most frequently performed NOTES procedure after cholecystectomy. The NOTES concept has provided a change in perspective for intramural and transmural endoscopic approaches to iatrogenic perforations during endoscopy. CONCLUSION: NOTES approaches have been implemented in clinical practice over the past decade. Selected techniques offer reduced invasiveness for patients with intra-abdominal emergencies, and may improve outcomes. Steady future development and adoption of NOTES are likely to follow as technology improves and surgeons become comfortable with the approaches.

Single-port and four-port laparoscopic cholecystectomy: difference in outcomes.

AIM: Patients prefer minimally invasive procedures with fast recovery, minimal pain and good cosmesis. Single-port cholecystectomy may decrease the need for narcotic pain medication and thus shorten recovery. Outcome-based evidence for this procedure is still being assembled. METHODS: Single-port cholecystectomy patients were matched based on age and gender with control patients undergoing four-port cholecystectomy during the same time. The primary endpoint was in hospital use of narcotic pain medication, measured by morphine equivalents. Secondary endpoints were operative time and length of stay. Statistical analysis was done by Student's t-test. RESULTS: Fifty patients (36 women, 14 men) underwent single port cholecystectomy between 11/2009-7/2012 and 50 patients underwent traditional cholecystectomy during the same time period. All patients were matched within 10 years of age. Morbidity was 4% for the single port group, 0% for the traditional cholecystectomy. There were no conversions to open cholecystectomy. The single-port group required a median of 29.0 mg (range, 8.7-180 mg) morphine equivalents of pain medication and the control group required a median of 33.2 mg (range, 0-185.7 mg) morphine equivalents (P=0.04). Single port cholecystectomy operative times were longer (median, 85 vs. 77 minutes, P=0.03). CONCLUSION: In this small study, there is a statistically significant difference in narcotic use during the initial hospital stay was measured between the two groups. After the initial ten cases, the operative time for single-port cholecystectomy approximated the standard four-port cholecystectomy. Prospective randomized controlled trials are necessary to investigate differences in outcomes between the two approaches.

Diagnostic transgastric endoscopic peritoneoscopy for staging of pancreatic and esophageal cancer.

Pancreatic and esophageal cancers are both gastrointestinal malignancies with relatively low long term survival. In part, the aggressiveness of these tumors is related to local and distant metastatic potential, subsequently affecting prognosis and treatment modalities. Currently, the mainstay of staging involves in-depth radiographic imaging with surgery offered for potentially curative tumors. As a result, staging becomes a key determinant in the role of surgical resection. As minimally invasive approaches continue to gain popularity, the idea of natural orifice surgery has been raised as a possible adjunct to staging neoplasias. Currently, the insertion of a perioral endoscope to gain access to the peritoneal cavity via a transgastric incision has been investigated, with demonstration of feasibility and efficacy in several animal studies and limited clinical studies. Similar techniques have been employed to gain access to the thoracic cavity via a transesophageal incision in early animal studies. This article aims to outline the advantages and limitations of natural orifice endoscopic surgery, and review the use of endoscopic techniques to assess the intraperitoneal cavity via a transgastric incision for determining local and widespread metastases with reference to pancreatic carcinoma. The method of transesophageal staging for esophageal carcinoma will also be discussed.

The challenges with NOTES retroperitoneal access in humans.

BACKGROUND: Animal studies have supported natural orifice transluminal endoscopic surgery (NOTES) retroperitoneal access. NOTES also may offer unique retroperitoneal access in humans. OBJECTIVES: This study was designed to assess the feasibility of endoscopic transgastric and transrectal retroperitoneal access in a cadaver model using prone and supine positioning, and to compare NOTES retroperitoneal examination with endoscopic ultrasound. METHODS: Using a multidisciplinary team, this institutional review board-approved study evaluated transgastric and transrectal retroperitoneal examination in six cadavers (3 male, 3 female; body mass index range, 25-37 kg/m(2)). Endoscopic ultrasound retroperitoneal examination preceded NOTES access. Transgastric Access: Using a prototype dual channel endoscope, a needle knife gastrotomy was created on the preantral posterior gastric wall. Retroperitoneal examination specifically targeted the pancreas and surrounding structures with the cadaver supine and prone. Transrectal Access: Using the same endoscope, a posterior needle knife rectotomy distal to the upper valve of Houston provided extraluminal access. Retroperitoneal examination proceeded with the cadaver prone and supine. Open dissection followed procedure completion. RESULTS: Access into the retroperitoneum succeeded at all sites. Significant challenges locating identifiable landmarks were faced-mostly transrectal and improved transgastric prone. All cadavers, despite body mass index or sex, had significant retroperitoneal adipose tissue limiting the endoscopic view. CONCLUSIONS: Although porcine studies have highlighted successful NOTES retroperitoneal procedures, the abundant human retroperitoneal adipose tissue challenged the translation of porcine research to humans. Additionally, although access to the retroperitoneal space and dissection within this space were accomplished easily, the appearance of cadaveric tissue and lack of blood flow made confident landmark identification impossible. Further study should continue in this area and focus on confident landmark identification for directed dissection. In a cadaveric model, this would best be improved by pre-NOTES anatomic marking or active perfusion of vasculature along with consideration of direct entry into the retroperitoneum from a targeted intraperitoneal site in clinical patients.

Functional and comparative evaluation of flexible monopolar endoscopic scissors.

BACKGROUND: The continued success of natural orifice translumenal endoscopic procedures requires reliable, accurate tissue dissection and suture cutting. This study aimed to evaluate a flexible endoscopic scissors prototype. METHODS: An acute study of two domestic swine was conducted. Laparoscopic access provided an overview and allowed comparison of the flexible endoscopic scissors with laparoscopic shears. The endoscopic cautery-compatible scissors consists of cutting blades with a flexible wire catheter assembly (outer diameter, 3.1 mm) for use within a therapeutic endoscopic channel. A dual-channel colonoscope was advanced through a gastrotomy created for peritoneal access. With the aide of a grasping forceps, multiple peritoneal biopsies were obtained using the endoscopic scissors. Cautery (Monopolar 18-30 W) then was attached to the scissors, and gallbladder dissection proceeded. The device then was used to perform a small bowel enterotomy. A timed comparison of this function with laparoscopic enterotomy was made. Finally, 3-0 Polyglactin 910 suture was cut using the endoscopic scissors. RESULTS: Peritoneal biopsies 2 cm(2) in size were obtained from multiple abdominal locations and endoscopic positions, including the retroflexed position. The scissors cut effectively and accurately. Cutting performance was enhanced with parallel countertraction provided by grasping forceps passed through the second endoscopic channel. The use of cautery with the scissors controlled small vessels (2-3 mm) and permitted partial dissection of the gallbladder from the hepatic bed. Small bowel enterotomy sufficiently large for stapler passage was created in 4 min and 54 s. Laparoscopically, this was completed in 1 min and 22 s. Suture was successfully cut at the first attempt in a controlled, reproducible fashion. CONCLUSIONS: Controlled tissue biopsy, dissection, enterotomy creation, and suture cutting can be performed with this endoscopic scissors. Endoscopic tissue dissection and enterotomy creation was completed effectively but less efficiently than with laparoscopy primarily due to parallel device use imposed by the dual-channel endoscope.

Management of common bile duct stones in a rural area of the United States: results of a survey.

BACKGROUND: Laparoscopic common bile duct exploration has been reported to be highly successful and cost-effective. It remains unknown to what extent the procedure is used in routine surgical practice. METHODS: We conducted a survey of general surgeons practicing in a rural area of the United States. The type of practice, laparoscopic training, performance of cholangiography, and preferred approach to choledocholithiasis were elicited. RESULTS: Sixty-eight of 207 surveys (33%) were returned. Thirty respondents (45%) indicated that they perform laparoscopic common bile duct explorations. The likelihood of laparoscopic common bile duct exploration increased with a higher number of cholecystectomies per year (p < 0.05, chi-square) but was independent of training or routine cholangiography. The preferred approach to a patient with choledocholithiasis was endoscopic retrograde cholangiopancreatography (75%), followed by laparoscopic (21%) and open exploration (4%). Reasons for not performing laparoscopic exploration were time (58%), equipment (24%), good gastrointestinal backup (6%), reimbursement (3%), increased morbidity (1.5%), lack of skill (1.5%), and other/no reason (18%). CONCLUSION: Although 45% of practicing surgeons indicated that they perform laparoscopic common bile duct explorations, only 21% practiced it as their preferred approach. Time constraints and lack of equipment are the main factors preventing the application of the laparoscopic technique toward choledocholithiasis.

Early conversion for gangrenous cholecystitis: impact on outcome.

BACKGROUND: Early conversion from laparoscopic to open cholecystectomy for patients with gangrenous cholecystitis has been advocated. This study investigated the impact of early conversion on patient outcome. METHODS: Data from all patients with gangrenous cholecystitis undergoing laparoscopic cholecystectomy between 1992 and 2002 whose procedure had been converted to open surgery were prospectively collected and analyzed. Morbidity, length of stay, intensive care unit admission, and operative time served as outcome measures. RESULTS: Of the 97 patients in the study, 33 underwent conversion to open cholecystectomy. The conversion was early for 24% of the patients, after the initial dissection, for 33% and after an extended attempt at completion of the laparoscopic cholecystectomy for 37%. There was no difference in the overall morbidity among the groups, whereas the length of hospital stay appeared to be longer in the early conversion group. The operative time was significantly shorter after early conversion (p < 0.01, chi-square test). CONCLUSION: Laparoscopic cholecystectomy is not feasible for all patients with gangrenous cholecystitis. However, a concerted effort to perform the cholecystectomy with the minimally invasive approach does not have an adverse impact on patient outcome and is likely to benefit patients although it poses a moderate risk of conversion.

Laparoscopic cholecystectomy for biliary dyskinesia: correlation of preoperative cholecystokinin cholescintigraphy results with postoperative outcome.

BACKGROUND: A gallbladder ejection fraction (EF) on cholescintigraphy of less than 35% after cholecystokinin (CCK) has been considered to be pathophysiologic and an indication for laparoscopic cholecystectomy (LC). METHODS: All patients undergoing LC for biliary dyskinesia between 1994 and 2001 were prospectively entered into a database. These patients were retrospectively evaluated with regard to demographics, the number of preoperative studies obtained, postoperative symptoms, and the number of postoperative studies obtained. RESULTS: Sixty patients underwent LC for biliary dyskinesia. The mean gallbladder EF was 14%, and 75% of patients were asymptomatic postoperatively. Persistent symptoms prompted further investigation in 6% of patients with a gallbladder EF <14% and in 35% of patients with an EF between 14 and 35% (p = 0.05). CONCLUSION: Laparoscopic cholecystectomy alleviated symptoms in 94% of patients with a gallbladder EF <14% after CCK injection. The diagnostic significance of a preoperative CCK cholescintigram (EF 14-35%) needs further investigation.

Recurrence rate after laparoscopic repair of recurrent inguinal hernias: have we improved?

Laparoscopic repair of recurrent inguinal hernias is becoming increasingly accepted in surgical practice, using an extraperitoneal or transabdominal approach for the placement of mesh. Previous literature reflects that efforts to perform open repair of recurrent inguinal hernias often result in further recurrences, testicular damage, or nerve injuries. Our study reflects physical examination of 37 patients over 4 years that underwent laparoscopic repair of recurrent inguinal hernia(s). Early and late complications are presented. The re-recurrence rate at this short follow up to 54 months is quite low at 2.5%. The laparoscopic repair of recurrent hernia reflects a very low likelihood of recurrence, low occurrence of testicular damage, and less likelihood of other such complications as nerve or spermatic cord injury (none of these occurred in this study). Seroma was clinically significant in 3 patients and no infections were noted. Our study and ongoing careful follow-up are the subject of this report.
