Long-term results of minimally invasive surgery for symptomatic epiphrenic diverticulum

Background

The real incidence of epiphrenic diverticulum is unknown, and only 15% to 20% of cases are symptomatic.

Methods

From January 1994 to May 2009, 20 patients were treated laparoscopically for this condition.

Results

The most common operation performed was transhiatal diverticulectomy with myotomy and partial fundoplication. No case was converted to open surgery. Esophageal leak occurred in 1 patient (5%). The postoperative courses were uneventful in the remaining 19 patients. After a median follow-up period of 52 months (range, 1–141 months), 1 patient had died of squamous cell carcinoma, 1 had mild solid-food dysphagia, 1 had chest pain, and 1 had heartburn. Manometry was performed postoperatively in 7 patients; all had normal lower esophageal sphincter pressure. In 5 patients who underwent 24-hour postoperative pH monitoring, pathologic reflux was absent.

Conclusions

In patients with symptomatic epiphrenic diverticulum, laparoscopic surgery is feasible, providing good access to the distal esophagus and inferior mediastinum. Long-term outcomes are satisfactory.     

Minimally invasive esophagectomy: the evolution and technique of minimally invasive surgery for esophageal cancer

Beginning with the widespread introduction of laparoscopic cholecystectomy in late 1989, minimally invasive surgical technique has been refined in conjunction with the development of advanced instrumentation and have subsequently been applied to increasingly complicated disease processes. Esophageal surgeons have increasingly incorporated minimally invasive surgery into their practice since the first laparoscopic fundoplication was described by Dallemagne et al. in 1991. Esophagectomy is associated with significant morbidity and mortality even in highly experienced centers. Many esophageal surgeons have had a great deal of interest in minimally invasive esophagectomy (MIE), which has the potential advantages of being a less traumatic procedure with a resultant improvement in postoperative convalescence and fewer wound and cardiopulmonary complications compared to the open approaches. Throughout the 1990s, as confidence with laparoscopic surgery of the esophagogastric junction grew, MIE was initially attempted with hybrid operations combining traditional open surgery with minimally invasive approaches. Subsequently, a totally laparoscopic transhiatal approach was described; however, this approach was perceived to be very challenging and has not gained widespread acceptance. Approaches used at present depend on cancer stage, cancer location, body habitus, and pulmonary function. For localized cancer (T1N0) or HGD, we prefer laparoscopic inversion esophagectomy (retrograde or antigrade). This approach may also be used for patients at high risk for thoracotomy. For locally advanced cancer in the middle third of the esophagus or for proximal third esophageal cancer, we prefer 3-field MIE (abdomen, and chest with neck anastomosis). For locally advanced cancer in the distal esophagus, especially in patients with a short thick neck, we prefer thoracoscopic-laparoscopic (2-field) esophagectomy (TLE).     

Minimally invasive video-assisted mitral valve surgery: our lessons after a 4-year experience

BACKGROUND: Right thoracotomy is a well known alternative to median sternotomy to gain access to the left atrium. To avoid the potential drawbacks associated with sternotomy coupled to the desire for a smaller scar and a more rapid rehabilitation in young and active patients, we investigated the purported advantages in patients undergoing video-assisted Port-Access mitral valve surgery. METHODS: Between February 1997 and November 2000, 175 patients (94 men, 81 women) with a mean age of 60 years (range 25 to 84) underwent either Port-Access mitral valve repair (n = 117) or replacement (n = 57) for degenerative disease (n = 112), rheumatic disease (n = 36), chronic endocarditis (n = 15), annular dilatation (n = 8), sclerotic disease (n = 2), and ingrowing myxoma (n = 1). There was one closure of a preexisting paravalvular leak. Standard Carpentier-Edwards repair procedures were used in all patients; in 14 patients polytetrafluoroethylene chordae were inserted for anterior leaflet prolapse. A total of 74 patients (42%) were in New York Heart Association functional class III/IV. RESULTS: Hospital mortality was 1.1% (n = 2). Four patients had conversion to sternotomy and conventional extra corporeal circulation for repair of a dissected aorta (n = 2) or the inabilty to proceed to a safe femoral cannulation (n = 2). Sixteen patients (9%) underwent a revision for bleeding. Mean cross-clamp time and perfusion time was 95 minutes (range 24 to 160) and 135 minutes (range 75 to 215) respectively. Mean intensive care unit and total hospital stay was 1.8 days (1 to 30) and 8.7 days (4 to 36), respectively. Three patients experienced late acute endocarditis: 2 had late mitral valve replacements and 1 patient had medical therapy for late prosthetic valve endocarditis. There were no myocardial infarctions, cerebrovascular events or peripheral ischemia due to thromboembolic phenomena. No wound complications were observed. The degree of patient satisfaction was very high. CONCLUSIONS: The video-assisted Port-Access mitral valve approach is a valid alternative to sternotomy, with the same standards of results and quality.     

Minimally invasive surgery for achalasia: A 10-year experience

Minimally invasive esophagomyotomy for achalasia has become the preferred surgical treatment; the employment of a concomitant fundoplication with the myotomy is controversial. Here we report a retrospective analysis of 53 patients with achalasia treated with laparoscopic Heller myotomy; fundoplication was used in all patients except one, and 48 of the fundoplications were complete (floppy Nissen). There were no deaths or reoperations, and minor complications occurred in three patients. Good-to-excellent long-term results were obtained in 92% of the subjects (median follow-up 3 years). Two cases (4%) of persistent postoperative dysphagia were documented, one of which was treated with dilatation. Postoperative reflux occurred in five patients, four of whom did not receive a complete fundoplication; these patients were well controlled with medical therapy. We suggest that esophageal achalasia may be successfully treated with laparoscopic Heller myotomy and floppy Nissen fundoplication with an acceptable rate of postoperative dysphagia.

Minimally invasive pancreatic surgery of the entire gland: initial experience

Many pancreatic cancer surgeons have been slow to adopt minimally invasive pancreatic surgery (MIPS) due a lack of formalized minimally invasive training and the perceived difficulty in dissecting pancreatic tumors and tissue away from the superior mesenteric vessels and consequent concerns for adequacy of oncologic margins and lymph node retrieval. A review of the first 29 MIPS procedures for malignant and premalignant tumors of the pancreas with the aid of a sterilizeable robotically-controlled camera holder was undertaken. As opposed to other robots currently available, this device allows for hand-assistance by the operating surgeon. Fourteen minimally invasive distal pancreatectomies (MIDP) (10 laparoscopic, 3 hand-assisted, 1 converted to open), 13 MIPDs (6 laparoscopic, 5 hand-assisted, 2 converted to open), and 2 laparoscopic central pancreatectomies have been performed. Seventeen (59%) of these patients were treated for cancer. Of these, 11 underwent a MIPD and 6 a MIDP. There were postoperative complications in seven patients (24%) at 30 days. Thirty and 90 day mortality was 3%. A sterilizeable robotically-controlled laparoscope holder that enables the operating surgeon to remain in contact with the patient and have the option of a hand-assisted approach may be particularly helpful for minimally invasive approaches to malignant and premalignant pancreatic tumors.     

Minimally invasive surgery combined with peroperative endoscopy for symptomatic middle and lower esophageal diverticula: a single institute's experience

INTRODUCTION: Esophageal diverticula are rare, accounting for less than 5% of dysphagia cases. Midesophageal and epiphrenic esophageal diverticula account for about 30% of all esophageal diverticula. Traditionally, thoracotomy or laparotomy were the preferred approaches for surgical therapy. Recently, minimally invasive therapies have been described. MATERIALS AND METHODS: We present our experiences of 12 patients with diverticula of the distal two-thirds of the esophagus. Thoracoscopic approach was used to treat midesophageal diverticula and a transhiatal approach was used for the epiphrenic diverticula. Peroperative endoscopy was used in all cases. Underlying causes were also simultaneously dealt with. DISCUSSION: According to our series, epiphrenic diverticula were more common; lateral wall being the most common location. Myotomy and fundoplication were done depending on the underlying disorder. We highlight the importance of peroperative endoscopy to accurately localize and determine extent of diverticulectomy. RESULTS: Males were more common than females and most patients were elderly. Postoperatively, 2 cases had complications and 1 patient had leak. The length of hospital stay was 3 to 23 days. CONCLUSIONS: Esophageal diverticula are rare conditions, and minimally invasive surgery is certainly feasible and effective in terms of reduced morbidity.     

Minimally invasive mitral valve surgery: a 6-year experience with 714 patients

BACKGROUND: This study analyzes a single institutional experience with minimally invasive mitral valve operations of 6 years, reviewing short-term morbidity and mortality and long-term echocardiographic follow-up data. METHODS: Seven hundred fourteen consecutive patients had minimally invasive mitral valve procedures between November 1995 and November 2001; concomitant procedures included 91 multiple valves and 18 coronary artery bypass grafts. Of these 714 patients, 561 patients had isolated mitral valve operations (375 repairs, 186 replacements). Mean age was 58.3 years (range, 14 to 96 years; 30.1% > 70 years), and 15.4% of patients had previous cardiac operations. Arterial cannulation was femoral in 79.0% and central in 21%, with the port access balloon endo-occlusion used in 82.3%. Cardioplegia was transjugular retrograde (54.1%) or antegrade (29.4%). Right anterior minithoracotomy was used in 96.6% and left posterior minithoracotomy in 2.2%. RESULTS: Hospital mortality for primary isolated mitral valve repair was 1.1% and 5.8% for isolated mitral valve replacement. Overall hospital mortality was 4.2% (30 of 714). Mean cross-clamp time was 92 minutes and mean cardiopulmonary bypass time was 127 minutes. Postoperatively, median ventilation time was 11 hours, intensive care unit time was 19 hours, and total hospital stay was 6 days. Complications for all patients included permanent neurologic deficit (2.9%), aortic dissection (0.3%); there was no mediastinal infection (0.0%). Follow-up echocardiography demonstrated 89.1% of the repair patients had only trace or no residual mitral insufficiency. CONCLUSIONS: This study demonstrates that the minimally invasive port access approach to mitral valve operations is reproducible with low perioperative morbidity and mortality and with late outcomes that are equivalent to conventional operations.     

Minimally invasive surgery for esophageal cancer: a review on sentinel node concept

Background

Lymphoadenectomy is a cornerstone of esophageal cancer treatment, and sentinel node (SN) biopsy (SNB) might provide surgeons with an extra tool to limit unnecessarily extended lymphadenectomy and to implement a minimally invasive approach. The aim of our study was to review all the available literature on the use of SNB in esophageal surgery for malignancy.

Methods

The review was conducted according to the PRISMA guidelines. A systematic search was performed in PubMed, EMBASE, and the Cochrane database to identify all original articles on the role of SNB in esophageal cancer. Data on methodologies, tumor stage and localization, and results were summarized and used to address relevant clinical questions related to the application of the SNB technique in esophageal cancer.

Results

Twelve studies were included, with a total of 492 patients. Different methods for SN identification were used (radionuclide, blue dye, computed tomography [CT] lymphography). The pooled values estimated using the random-effects model were, respectively: technetium-99 m overall detection rate (DR) 0.970 (95 % CI 0.814–0.996), accuracy (ACC) 0.902 (95 % CI 0.736–0.968); blue-dye DR 0.971 (95 % CI 0.890–0.993), ACC 0.790 (95 % CI 0.681–0.870); and CT lymphoscintigraphy DR 0.970 (95 % CI 0.814–0.996), ACC 0.902 (95 % CI 0.736–0.968).

Conclusion

Based on these results, the concept of SN in esophageal cancer is technically feasible with an acceptable DR and ACC, and it might be applicable in the event of early-stage adenocarcinoma of the gastroesophageal junction in patients with a high surgical risk or in a patient where an endoscopic resection is taken into consideration. Further studies focused on a single tumor type and localizations are needed in order to predict the correct utilization of this concept in minimally invasive treatment of esophageal cancer.     

Minimally invasive surgery for gastric stromal cell tumors: intermediate follow-up results

Laparoscopic wedge resection of the stomach (LWS) has become the treatment of choice for patients with benign gastric tumors. The technical consideration and long-term follow-up data of LWS for gastrointestinal stromal tumors (GISTs) of the stomach are limited. We present our experience of 28 LWSs for gastric GISTs with a mean follow-up of 43 months. From October 1995 to December 2002, we successfully performed 28 LWSs for 29 patients with GISTs of the stomach, and one patient needed conversion to laparotomy because of suspected bowel injury when establishing pneumoperitoneum. Patient demographics, perioperative parameters, and outcomes of the 28 patients were assessed retrospectively. The tumors were located in the upper third of the stomach in 13 patients, in the middle third, in eight patients, and in the lower third, in seven patients. The mean size of tumors was 3.4 ± 1.6 cm in diameter. The duration of operation ranged from 95 to 390 minutes: 189.6 ± 79.5 minutes with the stapler method and 194.3 ± 50.5 minutes with the hand-sewn method (P = 0.8870). No blood transfusion was given in the perioperative period in all cases. Cholecystectomy in three patients and repair of hiatal hernia in one patient were performed during the same operation. The oral intake was restored at the third to fourth postoperative days. The hospital stay ranged from 3 to 11 days (mean, 6.7 ± 1.8 days). The follow-up period ranged from 12 to 95 months (mean, 43.3 ± 23.5 months, median 42 months). There has been no evidence of tumor recurrence, including one patient with microscopic invasion of section margin. LWS can be performed safely with a satisfactory remission rate for patients with gastric stromal cell tumors.

Minimally invasive reoperative isolated valve surgery: early and mid-term results

OBJECTIVE: Minimally invasive, nonsternotomy approaches for valve procedures may reduce the risks associated with cardiac surgery after prior sternotomy and may improve outcomes. We analyzed our institutional experience to test this hypothesis. METHODS: Between 1995 and 2002, 498 patients with previous cardiac operations via sternotomy underwent isolated valve surgery: 337 via median sternotomy (aortic = 160; mitral = 177) and 161 via mini-thoracotomy (aortic = 61; mitral = 100). Data were collected prospectively using the New York State Cardiac Surgery Report Form. RESULTS: Preoperative incidences of congestive heart failure, renal disease, and nonelective procedures were higher in the sternotomy group. Hospital mortality was significantly lower with the minimally invasive approach, 5.6% (9/161) versus 11.3% (38/337) (univariate, p = 0.04). However, multivariate analysis (odds ratio: 95% confidence intervals, p value) revealed that chronic obstructive pulmonary disease (6.6: 1.4 to 3.1, p = 0.001), renal disease (4.1: 1.52 to 11.2, p = 0.01), cerebrovascular disease (2.2: 1.03 to 4.78, p = 0.04), and ejection faction <30% (1.5: 0.96 to 5.5, p = 0.06) were associated with increased mortality. While mean bypass time, cross-clamp times, and stroke rates were comparable between groups, patients undergoing minimally invasive valve surgery had no deep wound infections (0% vs 2.4%, p = 0.05), less need for blood products (p = 0.02), and shorter hospital stays (p = 0.009). Five-year survival was higher with minimally invasive techniques as compared to a sternotomy approach (92.4 +/- 2% and 86.0 +/- 2%, respectively, p = 0.08). CONCLUSIONS: Reoperative valve surgery can be safely performed using a nonsternotomy, minimally invasive approach, with at least equal mortality, less hospital morbidity, decreased hospital length of stay, and slightly favorable mid-term survival as compared to sternotomy.     

Endoscopic radial artery harvesting: our initial experience and results of the first 25 patients.

BACKGROUND: The radial artery has become an increasingly popular arterial conduit for coronary artery bypass grafting (CABG). However, the traditional open harvesting technique requires a long incision, and is therefore associated with some wound complications and cosmetic problems. Here, we describe our experience of endoscopic radial artery harvesting (ERAH) through a small incision in 25 patients who underwent CABG. MATERIALS AND METHODS: Between February 2, 2004 and January 7, 2005, a total of 25 patients (4 females; mean age: 64+/-10 years) underwent ERAH using the VasoView System (Guidant Corporation, Indianapolis, IN) at our institution. All patients underwent a preoperative Allen test to assess the competence of the palmer arch. Twenty-four radial arteries were harvested from the nondominant arm and one from the dominant arm. The mean clinical follow-up was 8+/-2.9 months. RESULTS: All radial arteries were harvested through a 2-cm incision at the wrist, successfully removed with ERAH and successfully used as CABG conduits. The mean harvest time was 59+/-11 min, and the mean harvested length was 17+/-1.7 cm. No adjunctive procedures were required during vessel harvesting, and no conversions to the open technique were necessary. Harvesting complications included 2 cases of postoperative hematoma and 7 cases of superficial radial nerve paresthesia. Five postoperative angiographies were performed and all radial arteries were patent. Overall, 24/25 (96%) patients were satisfied with the procedure. CONCLUSION: The ERAH technique was performed as safely as the traditional open technique and the harvested radial arteries were acceptable as CABG conduits. In particular, patient satisfaction with the procedure regarding the cosmetic results was excellent.     

Minimally invasive surgery for female urinary incontinence: experience with periurethral microballoon implantation

PURPOSE: To assess the effectiveness of periurethral microballoon implantation for management of female urinary incontinence. PATIENTS AND METHODS: A total of 45 women with urinary incontinence (age range 47-88 years) were treated between May 2000 and June 2001. Microballoons were placed in the proximal periurethral tissue using endoscopic instrumentation under local anesthesia. Follow-up assessment including urodynamic study and quality- of-life assessment was performed at 1, 3, and 6 months. RESULTS: Implantation was successful in all cases with no significant adverse effects. Cure was achieved in 60% and improvement in 5%. The failure rate was 35%. Microballoon implantation significantly increased the mean urethral closure pressure, from 35.2 cm H(2)O (SD 14.9; range 15-72 cm H(2)O) to 46.5 cm H(2)O (SD 19.7; range 16-87 cm H(2)O) (P = 0.001). The best predictors of successful outcome in univariate analysis were initial urethral closure pressure (P = 0.047) and degree of incontinence (P < 0.001). CONCLUSIONS: Periurethral microballoon implantation is a useful technique for the management of female urinary incontinence, especially in elderly and inoperable patients. The microballoons do not present the adverse effects associated with other bulking agents.     

Minimally invasive aortic valve surgery: technical considerations and results with the parasternal approach

BACKGROUND: The history of surgery over the last 30 years has moved steadily toward minimally invasive surgery; more recent experience with the gall bladder, arthroscopy, and video-assisted thoracic surgery has confirmed this trend. METHODS: Our experience in minimally invasive valve surgery between July 1996 and October 1997 included 180 patients, 80 with aortic valve replacement and 100 with mitral valve replacement. The 80 aortic valve replacement patients consisted of 46 males and 34 females, with a mean age of 63 years (range 32 to 90 years) and mean New York Heart Association Functional Class 2.5. The etiology of disease was varied: degenerative in 41 patients, congenital in 17, rheumatic in 8, subacute bacterial endocarditis in 6, myxomatous in 4, and structural valve degeneration in 4. RESULTS: There were two (2.5%) operative deaths, both from multisystem organ failure. Only 16 (20%) of the 80 patients experienced new postoperative atrial fibrillation. The mean length of stay in the hospital was 5 days (range 3 to 24 days). Only 18 (23%) of the 78 surviving patients required posthospital rehabilitation, and there were no late deaths. Morbidity included cerebrovascular accident in 1 patient (1.2%), sternal infection in 1 (1.2%), groin infection in 1 (1.2%), and bleeding requiring reoperation in 1 (1.2%). CONCLUSIONS: Minimally invasive cardiac valve surgery is extremely effective and has become our current technique of choice in every mitral and aortic valve patient who does not have coronary artery disease because it reduces the length of hospital stay and cost, requires fewer blood transfusions, and stimulates less atrial fibrillation.     

Minimally invasive surgery in colon cancer patients leads to improved short-term outcomes and excellent oncologic results

Background

Minimally invasive surgery (MIS) techniques are beneficial compared with open techniques. There is a paucity of data of the potential advantages of MIS in colon cancer surgery for veterans. Therefore, we hypothesize that use of MIS in colon cancer resections in a Veterans Affairs Medical Center will lead to improved short-term outcomes without compromising oncologic outcomes.

Methods

A retrospective analysis of a prospectively maintained database was performed. We compared surgical, short-term, and oncologic outcomes in MIS versus open surgery.

Results

MIS patients had significantly less blood loss, surgical time, days to return of bowel function, and hospital and intensive care unit stays. Also, they had a greater and more adequate lymphadenectomy, and were less likely to experience a postoperative complication. Survival analyses showed no difference in overall and disease-free survival.

Conclusions

The use of MIS in colon cancer leads to improved short-term outcomes and similar oncologic outcomes when compared with open surgery.     

Minimally invasive surgery: the evolution of fellowship

BACKGROUND: The field of postgraduate minimally invasive surgery/gastrointestinal surgery (MIS/GIS) training has undergone substantial growth and change. To determine whether fellowships are meeting a strategic need in training, we conducted a survey to assess the current status and trends of change in MIS/GIS fellowships. METHODS: A survey was distributed to fellows currently in MIS/GIS programs in the United States and Canada in 2003 and 2006. Fellows were asked to describe demographics as well as their experience both during fellowship and residency. We compared this with aggregate data of resident experience through the Accreditation Council for Graduate Medical Education (ACGME) case logs, data tracked by industry, and program data from the Fellowship Council (FC) web site. RESULTS: There were 54 responses to the 75 surveys distributed in 2006 (72% response rate). MIS fellows performed more laparoscopic cases during their residency than the average graduating chief resident, but did not feel competent to perform advanced laparoscopic surgery. However, combining fellowship numbers with residency numbers does suggest that the total experience provides competency in a wide variety of procedures. CONCLUSIONS: It seems that the MIS/GIS Fellowship is meeting a real need among graduating surgical residents; fellows felt unprepared for clinical practice at the completion of residency. It is encouraging to note the improvements in fellowship structure, standards, and overall experience, brought by the efforts of the FC. It is hoped that this report of the state of MIS fellowship with a comprehensive review of current data will aid in further evaluation and improvement.     

Minimally invasive technology for mitral valve surgery via left thoracotomy: experience with forty cases

BACKGROUND: Recent evolution of minimally invasive technology has expanded the application of the right thoracotomy approach for mitral valve surgery. These same technological advances have also made the left posterior minithoracotomy approach attractive in complex mitral procedures. METHODS: From 1996 to 2003, 921 isolated mitral valve procedures were performed without sternotomy; 40 (4.3%) of these were performed via left posterior minithoracotomy. In the left posterior minithoracotomy group, ages ranged from 18 to 84 years; 36 patients had had previous cardiac surgery (9 on > or =2 occasions). Other factors precluding right thoracotomy included mastectomy/radiation and pectus excavatum. RESULTS: Arterial perfusion was via femoral artery (n = 26) or descending aorta (n = 14); long femoral venous cannulas with vacuum-assisted drainage were used in 39 procedures. Two patients had direct aortic crossclamping, 18 had hypothermic fibrillation, and 20 had balloon endoaortic occlusion. The mean crossclamp and bypass times were 81.9 and 117.2 minutes, respectively. Hospital mortality was 5.0% (2/40); both deaths occurred in octogenarians. There were no injuries to bypass grafts or conversions to sternotomy. Complications included perioperative stroke (2/40; 5.0%), bleeding (2/40; 5.0%), and respiratory failure (1/40; 2.5%); 28 patients (70%) had no postoperative complications. There was no incidence of perioperative myocardial infarction, renal failure, sepsis, or wound infection. The median length of stay was 7 days. CONCLUSIONS: Advances in minimally invasive cardiac surgery technology are readily adaptable to a left-sided minithoracotomy approach to the mitral valve. The left posterior minithoracotomy approach is a valuable option in complicated reoperative mitral procedures with acceptable perioperative morbidity and mortality.     

Contemporary perioperative results of cardiac surgery in the elderly- our experience

Objective  

With progressive aging of population in developing nations, cardiac surgeons increasingly face elderly patients. These patients are usually symptomatic, yet at high risk for intervention. This study aims to review our experience in elderly Indian patients.
