ABSTRACT

Patients requiring abdominal wall reconstruction may have medical comorbidities and/or complex defects. Comorbidities such as smoking, diabetes, obesity, cirrhosis, and frailty have been associated with an increased risk of postoperative complications. Prehabilitation strategies are variably associated with improved outcomes. Large hernia defects and loss of domain may present challenges in achieving fascial closure, an important part of restoring abdominal wall function. Prehabilitation of the abdominal wall can be achieved with the use of botulinum toxin A, and preoperative progressive pneumoperitoneum.

ABSTRACT

A 67-year-old woman with endometrial adenocarcinoma had sustained an aortic injury during robotically assisted retroperitoneal lymphadenectomy. Repair could not be performed laparoscopically; however, graspers were used to maintain hemostasis while conversion to open surgery was initiated. Safety mechanisms locked the graspers in place, preventing tissue release, but resulting in additional aortic injury. Forceful removal of the graspers was eventually successful, and definitive aortic repair was then performed. Vascular surgeons who are not familiar with robotic surgery techniques should be aware that removal of robotic hardware requires the use of stepwise algorithms, which, if performed out of order, can introduce significant challenges.

ABSTRACT

OBJECTIVES: The primary objective of this study is to investigate whether undergraduate, nonmedical students could pass the FLS Manual Skills Exam with minimal practice. The secondary objective is to examine ACGME case log data from graduating chief residents over the past 18 years to examine how laparoscopic experience has evolved over that time period. DESIGN: Undergraduate, nonmedical students received training and unlimited practice time before being tested on each task of the FLS Manual Skills Exam. Each task was timed and scored using the MISTELS system. ACGME case log data from graduating chief residents over the past 18 years was obtained. SETTING: The setting is SimPortal, the simulation center associated with the University of Minnesota Medical School. PARTICIPANTS: The participants are 25 undergraduate, nonmedical students from the University of Minnesota. Participants were recruited on campus. RESULTS: Twenty-three out of 25 (92%) undergraduate, nonmedical students successfully completed one attempt for each task of the FLS Manual Skills Exam and 21 out of 25 (84%) completed both attempts. The average total practice time was 39 minutes. Over the past 18 years, the average number of laparoscopic cases completed by a graduating chief increased from 142 to 275 cases (93% increase). Additionally, the average number of cases of the top 5 most common laparoscopic operations increased from 25% to over 400%. CONCLUSIONS: Undergraduate, nonmedical students can pass the FLS Manual Skills Exam with minimal practice. Additionally, general surgery residents and medical students continue to gain more laparoscopic experience throughout medical training as laparoscopic surgery is utilized for more operations. The FLS Manual Skills Exam should be re-examined to determine its utility as a high-stakes exam.

ABSTRACT

OBJECTIVE: To assess the medical student perception and experience of a 24-hour call requirement, and to learn if improvements can be made to improve the 24-hour call requirement. DESIGN: Medical students completing their required surgical clerkship over 1 academic year at our institution were surveyed prior to their clerkship and on the last week of clerkship regarding their perceptions and experience with 24-hour call. SETTING: This study was performed at the University of Minnesota, in Minneapolis, Minnesota, a medical school and tertiary medical center. PARTICIPANTS: Two hundred one medical students were given the option to complete an anonymous survey before and after their required surgical clerkship. RESULTS: Response rate for the preclerkship survey was 70% (n = 140) and 58% (n = 117) for the postclerkship survey. The mean age of respondents was 26 years, and the majority of students were in their third year of medical school. After completing the clerkship, students interested in surgery more often agreed the 24-hour call requirement should remain (51% versus 31%, p = 0.01). Students rotating at a Level I Trauma Center were also more likely to agree the call requirement should remain (59% versus 33%, p = 0.008). Medical students generally had less concerns (mental health, fatigue, mistakes, and grade performance) related to 24-hour call after completion of the clerkship. Concerns about the effect of 24-hour call on study schedule remained high in both pre and postclerkship groups. CONCLUSIONS: Medical students have concerns about the experience prior to the clerkship that diminished by its completion. To improve medical student perceptions and overall experience of 24-hour call, frequency of shifts could be limited and the 24-hour call requirement sites could be shifted to Level I Trauma Centers.

ABSTRACT

BACKGROUND: Robotic groin hernia repair (r-TAPP) is demonstrating rapid adoption in the US. Barriers in Europe include: low availability of robotic systems to general surgeons, cost of robotic instruments, and the perception of longer operative time. METHODS: Patients undergoing r-TAPP in our start-up period were prospectively entered in the EuraHS database and compared to laparoscopic TAPP (l-TAPP) performed by the same surgeon within the context of two other prospective studies. Operations were performed with the daVinci Xi robot and the primary endpoint was skin-to-skin operative time. RESULTS: Following proctoring in September 2016 by US surgeons, 50 r-TAPP (34 unilateral and 16 bilateral) procedures have been performed up to January 2017. Mean operative time for unilateral r-TAPP was 54 min, with a decrease from 63 min for the first tertile to 44 min for the third tertile. For unilateral l-TAPP, the mean operative time was 45 min. Mean operative time for bilateral r-TAPP was 78 min, with a decrease from 90 min for the first half to 68 min for the second half. For bilateral l-TAPP, the mean operative time was 61 min. There were no intraoperative complications and no conversions to conventional laparoscopy or open surgery. The operation was performed as an outpatient in 67% of cases. Urinary retention requiring urinary catheterization was the only early postoperative complication noted in 5 patients (10.2%). At 4 week follow-up, 7 patients (14.3%) had an asymptomatic seroma, but no other complications were seen. CONCLUSION: Robotic TAPP was associated with a rapid reduction in operative time during our learning curve and afterwards the operative time to perform a robotic TAPP equals the operative time to perform a laparoscopic TAPP, both for unilateral and for bilateral groin hernia repairs. No complications related to the introduction of robotic-assisted laparoscopic groin hernia repair were observed.

ABSTRACT

Incisional hernia is a frequent complication of midline laparotomy and enterostomal creation and is associated with high morbidity, decreased quality of life, and high costs. The International Symposium on Incisional Hernia Prevention was held October 19-20, 2017, at the InterContinental Hotel in San Francisco, CA, hosted by the Department of Surgery, University of California, San Francisco. One hundred and three attendees included general and plastic surgeons from 9 countries, including principal participants for several of the seminal studies in the field. Over the course of the 2-day meeting, there were 38 oral presentations, 3 keynote lectures, and 2 panel discussions. The Symposium was a combination of new information but also a comprehensive review of the existing data so as to assess the current state of the field and to set the stage for future research. Further, the Symposium sought to increase awareness and thus emphasize the importance of preventing the formation of incisional and enterostomal hernias.

ABSTRACT

Gastric carcinoma after gastric bypass is rare. Extremely well-differentiated adenocarcinoma (EWDA) of the stomach is a rare variant that has been mostly reported in Japan. We present a case of a 68-year-old man with EWDA arising in the bypassed stomach that presented as a colonic pseudo-obstruction (CPO). Several imaging, endoscopic and pathologic studies performed in the course of 2 months were non-diagnostic. An iatrogenic duodenal perforation during a diagnostic procedure led to an emergent exploratory laparotomy in which the dilated colonic segment was resected. Pathologic examination showed metastatic EWDA in the colonic wall. Post-operative complications led to the patient's demise. At autopsy the primary tumor was identified in the blind pouch of the bypassed stomach. A literature review on gastric EWDA and carcinomas arising in bypassed stomachs is discussed. EWDA of the stomach is rare, difficult to diagnose, and shows an aggressive clinical course discordant with its near-benign histology. Gastric cancer arising in a bypassed stomach is uncommon; when it occurs it is usually diagnosed at advanced stage. Surveillance of the blind pouch is not currently recommended. Malignant infiltration of the colonic wall should be included in the differential diagnosis of CPO of unclear etiology.

ABSTRACT

BACKGROUND: Endoscopic sclerotherapy using sodium morrhuate has been used to treat patients with weight regain after Roux-en-Y gastric bypass whose presumed etiology is loss of restriction due to gastrojejunostomy dilation. Weight loss and stability have been demonstrated in several studies with short-term follow-up evaluation. METHODS: This retrospective review evaluated all the patients who underwent sclerotherapy for a dilated gastrojejunostomy between 2007 and 2012. RESULTS: The study identified 48 patients with a mean follow-up period of 22 months (range 12-60 months). The mean age of these patients was 47.5 ± 10.5 years, and 92 % were women. The average weight loss from the primary procedure was 132.5 ± 54.82 lb, and the average weight regain from the lowest weight to the maximum weight before sclerotherapy was 46 ± 40.32 lb. The median number of sclerotherapy sessions was two (range 1-4). The pre-procedure mean gastrojejunostomy diameter was 20 ± 3.6 mm, and the mean volume of sodium morrhuate injected per session was 12.8 ± 3.7 ml. The average weight loss from sclerotherapy to the final documented weight was 3.17 ± 19.70 lb, which was not statistically significant. The following variables in the multivariate analysis were not associated with statistically significant weight loss: volume of sodium morrhuate, patient age, gastrojejunostomy diameter, number of sclerotherapy sessions, decrease in gastrojejunostomy diameter between the first and second sessions, and number of follow-up years. Weight stabilization or loss was achieved by 58 % of our cohort, with a mean weight loss of 15.9 ± 14.6 lb in this subgroup. CONCLUSION: The long-term follow-up evaluation of patients undergoing sclerotherapy of the gastrojejunostomy for weight regain after gastric bypass showed only a marginal weight loss, which was not statistically significant in our study population, although more than 50 % of the patients achieved weight loss or stabilization.

ABSTRACT

OBJECTIVE: The aim of the study was to determine whether a standardized orientation to basic laparoscopy makes a positive effect on the experience of third-year medical students. STUDY DESIGN: Fifty-three third-year medical students at the University of Missouri, Columbia were randomly divided into 2 groups during their clerkship orientation. Both groups received a 40-minute laparoscopic hands-on training simulation guided by instructors. However, only 1 group was given a 20-minute multimedia presentation on introduction to laparoscopy that covered equipment, set up, troubleshooting, and different methods of access into the abdomen. Both groups were given a preclerkship and postclerkship survey where students were asked to rate their experience, comfort, and interest in surgery on a 10-point Likert scale. RESULTS: Hundred percent of the students receiving the combined hands-on training simulation and the 20-minute presentation felt that the experience helped during their clerkship (p = 0.002) and 92% felt it had a positive effect (p = 0.501). In contrast, only 72% of the group that received the hands-on training simulation alone found it helpful (p = 0.029) and 86% thought it had a positive effect (p = 0.508). There was no statistical difference between either group with regard to their perceived comfort with assistance in the operating room and with laparoscopy. Neither experience had a statistical effect on a students' interest in surgery as a career. CONCLUSIONS: Our results demonstrate how a standardized orientation to basic laparoscopy can make a positive effect on a student's experience; however, it fails to transition into a student's interest in surgery as a profession or in their perceived comfort level in the operating room. Our study suggests that a student's surgical interest is highly variable and composed of multiple experiences that occur during their clerkship that ultimately affects their perception of surgery as a field and profession.

ABSTRACT

BACKGROUND: We hypothesized that an esophageal nitinol stent that is mainly silicone-covered but partially uncovered may allow tissue ingrowth and decrease the migration rate seen with fully covered stents and still allow safe stent removal. The aim of this study was to evaluate the first human results of using partially covered stents for anastomotic complications of bariatric surgery. METHODS: This was a retrospective evaluation of all patients with staple-line complications after bariatric surgery who received a partly covered stent at a single tertiary-care bariatric center. The stents varied in length from 10 to 15 cm and in diameter from 18 to 23 mm. RESULTS: From April 2009 to April 2010, eight patients received partially covered stents on 14 separate occasions. The indications were gastrojejunal stricture in four, acute leak in two, acute leak followed by a later stricture in one, and a perforated anastomotic ulcer in one patient. Single stents were placed in 12 sessions and two overlapping stents in two sessions. At the time of stent deployment, one patient had the uncovered proximal end of the stent in the stomach, with all others in the distal esophagus. Immediate symptom improvement occurred in 12/14 stent placements. Oral nutrition was initiated for 10/14 stent treatments within 48 h. Stents were removed after 25 ± 10 days. Minor stent displacement occurred with 9/13 stents, with the proximal end of the stent moving into the stomach, though the site of pathology remained covered. The stents were difficult to remove when tissue ingrowth was present. One patient required laparoscopic removal and one required two endoscopy sessions for removal. At the time of removal of ten stents, where the proximal end was found in the stomach, four had gastric ulceration, three had gastric mucosa replaced by granulation tissue, and three had normal gastric mucosa. In four cases where the proximal portion of the stent stayed in the esophagus, the esophageal deployment zone had abnormalities: three with granulation tissue and one with denuding of the esophageal mucosa. The distal uncovered portion of the stent in the Roux limb never became embedded in the mucosa and caused minimal injury. CONCLUSIONS: A partially covered stent was successful in keeping the site of the pathology covered and provided rapid symptom improvement and oral nutrition in most patients. The proximal end of the stent generally moved from the esophagus to the stomach, probably due to esophageal peristalsis. The proximal uncovered portion of the stent causes significant bowel mucosal injury and sometimes becomes embedded in the esophagus or the stomach, making removal difficult. We no longer use partially covered stents.

ABSTRACT

BACKGROUND: Failure of primary bariatric surgery is frequently due to weight recidivism, intractable gastric reflux, gastrojejunal strictures, fistulas, and malnutrition. Of these patients, 10-60% will undergo reoperative bariatric surgery, depending on the primary procedure performed. Open reoperative approaches for revision to Roux-en-Y gastric bypass (RYGB) have traditionally been advocated secondary to the perceived difficulty and safety with laparoscopic techniques. Few studies have addressed revisions after RYGB. The aim of the present study was to provide our experience regarding the safety, efficacy, and weight loss results of laparoscopic revisional surgery after previous RYGB and sleeve gastrectomy procedures. METHODS: A retrospective analysis of patients who underwent laparoscopic revisional bariatric surgery for complications after previous RYGB and sleeve gastrectomy from November 2005 to May 2007 was performed. Technical revisions included isolation and transection of gastrogastric fistulas with partial gastrectomy, sleeve gastrectomy conversion to RYGB, and revision of RYGB. The data collected included the pre- and postoperative body mass index, operative time, blood loss, length of hospital stay, and intraoperative and postoperative complications. RESULTS: A total of 26 patients underwent laparoscopic revisional surgery. The primary operations had consisted of RYGB and sleeve gastrectomy. The complications from primary operations included gastrogastric fistulas, refractory gastroesophageal reflux disease, weight recidivism, and gastric outlet obstruction. The mean prerevision body mass index was 42 ± 10 kg/m(2). The average follow-up was 240 days (range 11-476). The average body mass index during follow-up was 37 ± 8 kg/m(2). Laparoscopic revision was successful in all but 1 patient, who required conversion to laparotomy for staple line leak. The average operating room time and estimated blood loss was 131 ± 66 minutes and 70 mL, respectively. The average hospital stay was 6 days. Three patients required surgical exploration for hemorrhage, staple line leak, and an incarcerated hernia. The overall complication rate was 23%, with a major complication rate of 11.5%. No patients died. CONCLUSION: Laparoscopic revisional bariatric surgery after previous RYGB and sleeve gastrectomy is technically challenging but compared well in safety and efficacy with the results from open revisional procedures. Intraoperative endoscopy is a key component in performing these procedures.

ABSTRACT

A minimally invasive component separation may lead to a dynamic abdominal wall after hernia repair, with reduced complications. We present early results of our patients undergoing this technique. Five patients were selected for open midline repairs; three with chronic infections, one with a prior midline skin graft, and one who desired a primary, tension-free repair. These three males and two females had a mean age of 50.8 +/- 21.1 years and body mass index of 30.9 +/- 6.2. The mean number of previous abdominal operations was 7 +/- 3.4 and previous attempted hernia repairs were 4 +/- 2.7. All patients had a midline laparotomy with lysis of adhesions. An endoscopic component separation was then performed bilaterally. Drains were left in the dissection bed. All patients had the midline closed; four received biologic mesh underlays. Mean operative time was 227 minutes +/- 49. Mean length of stay (LOS) was 9.2 days +/- 3.6. Early median follow-up was 6 months (range 0.25-9). Two patients required postop transfusions, and two patients had mild complications of the midline wound (hematoma, infection). To date, one recurrence was diagnosed by CT scan. Early evaluation of adopting the minimally invasive (MIS) component separation demonstrates minimal complications and good initial outcomes.

ABSTRACT

INTRODUCTION: Incisional hernias of the flank are rare with scattered case reports regarding the feasibility of laparoscopic treatment. Treatment can be technically challenging due to patient positioning and adequate mesh overlap and fixation. The aim of this study is to describe the surgical technique and present outcomes of the largest known case series of laparoscopic repair of flank hernia. METHODS: A retrospective chart review was performed from April 2002 to August 2006 at two university hospitals utilizing three surgeons' experience. All patients who underwent a laparoscopic repair of a flank hernia were identified and reviewed with regards to short-term outcomes. RESULTS: Twenty-seven patients were identified with incisional flank hernia treated laparoscopically. Average defect size was 188 cm(2) repaired with an average mesh size of 650 cm(2). Mean operating room (OR) time was 144 min and mean length of stay (LOS) was 3.1 days. There were two reoperations within the cohort: one for a new, unrelated midline hernia 7 months after repair of the initial flank hernia and one for chronic pain with removal of a previously placed polypropylene mesh in the subcutaneous tissue of the abdominal wall. Neither patient had failure of the laparoscopic flank hernia repair. Two other patients were conservatively treated for chronic pain. Mean follow-up was 3.6 months. CONCLUSIONS: In the laparoscopic repair of flank hernias adequate retroperitoneal dissection and wide mesh overlap is imperative. Laparoscopic repair can be performed safely and effectively with good short-term outcomes.

ABSTRACT

BACKGROUND: Laparoscopic ventral hernia repair (LVHR) can be challenging in patients with large abdominal wall defects and loss of domain (LOD). When hernia contents are reduced, the pneumoperitoneum preferentially fills the sac, leaving no space for mesh manipulation. This study presents a modification for LVHR in LOD patients, as well as outcomes for a series of patients. METHODS: Between September 2002 and August 2004, 10 patients with large ventral hernias and LOD underwent attempts at LVHR. The technique is modified by placing additional trocars to allow for fixation from above the mesh. Patient data were harvested from a prospective database and analyzed. RESULTS: All hernias were recurrent in nature. Mean defect size was 626 cm(2), requiring 1 to 4 pieces of sutured Gore Dualmesh for a tension-free repair. Three patients' procedures were aborted after adhesiolysis, with concerns about missed enterotomies. All 3 underwent delayed mesh placement within the same hospitalization. Only 2 were successful. The third patient had significant bowel edema precluding mesh placement. Two patients were converted to open repairs (Rives-Stoppa and component separation). There were no mortalities, but there were 2 major complications: inferior vena cava thrombosis and transient abdominal compartment syndrome. In follow-up (7.7 months) there were 2 recurrences secondary to excision of infected mesh. CONCLUSION: It is possible to obtain a successful LVHR in patients with large defects and LOD. The technique is complex and is modified to allow for mesh fixation from above the mesh. Frequent change in patient positioning allows for visualization below the fascial defect.

ABSTRACT

BACKGROUND: To analyze the outcomes of a series of endoscopically placed polyester self-expanding polyflex stents (SEPSs) for the management of anastomotic leaks after Roux-en-Y bypass. Anastomotic leaks after gastric bypass cause significant morbidity and mortality. Covered polyester SEPSs might have a role in the treatment of these leaks. METHODS: A retrospective chart review was performed from January 2006 to November 2006 that included all acute and chronic leaks treated with SEPSs. RESULTS: A total of 6 patients were treated with stents, with a mean procedure time of 22 minutes. Of these 6 patients, 5 had acute postoperative leaks and 1 had a chronic fistula. Five patients started oral intake 1-6 days after their procedure. All acute leaks had complete healing at a median of 44 days. The patient with a chronic gastrocutaneous fistula required revisional surgery for fistula closure. In addition, 5 patients had stent migration, and 3 required stent replacement. CONCLUSION: An endoscopically placed SEPS provides a less-invasive alternative to treat acute anastomotic leaks after Roux-en-Y bypass while simultaneously allowing oral intake. The results of this case series have demonstrated this treatment to be safe and effective.

ABSTRACT

BACKGROUND: Complications after bariatric surgery often require longterm parenteral nutrition to achieve healing. Recently, endoscopic treatments have become available that provide healing while allowing for oral nutrition. The purpose of this study was to present outcomes of the largest series to date treating staple line complications after bariatric surgery with endoscopic covered stents. STUDY DESIGN: A retrospective evaluation was performed of all patients treated for staple line complications after bariatric surgery at a single tertiary care bariatric center. Acute postoperative leaks, chronic gastrocutaneous fistulas, and anastomotic strictures refractory to endoscopic dilation after both gastric bypass and sleeve gastrectomy were included. RESULTS: From January 2006 to June 2007, 19 patients (11 with acute leaks, 2 with chronic fistulas, and 6 with strictures) were treated with a total of 34 endoscopic silicone covered stents (23 polyester, 11 metal). Mean followup was 3.6 months. Immediate symptomatic improvement occurred in 90% (91% of acute leaks, 100% of fistulas, and 84% of strictures). Oral feeding was started in 79% of patients immediately after stenting. Resolution of leak or stricture after stent treatment occurred in 16 of 19 patients (84%). Healing of leak, fistula, and stricture occurred at means of 33 days, 46 days, and 7 days, respectively. Three patients (1 with leak, 1 with fistula, and 1 with stricture) had unsuccessful stent treatment. Migration of the stent occurred in 58% of 34 stents placed. Most migration was minimal, but three stents were removed surgically after distal small bowel migration. There was no mortality. CONCLUSIONS: Treatment of anastomotic complications after bariatric surgery with endoscopic covered stents allows rapid healing while simultaneously allowing for oral nutrition. The primary morbidity is stent migration.
