Comparison between major and minor surgical procedures for the treatment of chronic staple line disruption after laparoscopic sleeve gastrectomy

Factors that promote successful endoscopic management of laparoscopic sleeve gastrectomy leaks

INTRODUCTION

Staple line leaks following laparoscopic sleeve gastrectomy (LSG) are associated with significant morbidity and mortality. Endoluminal techniques, including stent placement and endoluminal vacuum therapy (EVAC), have become viable options to treat these patients without the need for additional surgery. The purpose of this study was to define the conditions where certain endoscopic therapies are most likely to succeed compared to surgery.

METHODS

An IRB approved prospectively maintained database was retrospectively reviewed for all patients treated for gastrointestinal leaks from July 2013 to March 2019. All patients who were treated for gastrointestinal leaks following LSG were included. Endpoints include success of leak closure and hospital-related morbidity for the patients treated solely by endoscopic only methods (EP) compared to the additional surgery group (SP).

RESULTS

There were 39 patients (33 females; 6 males) with a median age of 45.9 years. The EP group included 23 patients (59%), whereas SP included 16 patients (31%). On average, the SP had longer days from sentinel surgery to our hospital admission (70 vs 41), a higher percentage of previous bariatric surgery prior to sentinel LSG (50% vs 17%), and a higher readmission rates following discharge (50% vs 39%). Total length of stay was also higher in the SP compared to the EP (45.4 vs 11). Using this data, a treatment algorithm was developed to optimally treat future patients who suffer from gastrointestinal leaks following LSG.

CONCLUSIONS

Endoscopic therapies, such as EVAC, stent placement, internal drainage, and over-the-scope clips, have a higher chance of success if performed earlier to their sentinel surgery and if patients have had no prior bariatric surgeries. Patients who require additional surgery tend to have longer hospital stays and readmission rates. Using the treatment algorithm provided can help determine when endoscopic therapies are likely to succeed.

Reoperative surgery for nonresponders and complicated sleeve gastrectomy operations in patients with severe obesity. An international expert panel consensus statement to define best practice guidelines

BACKGROUND

Laparoscopic sleeve gastrectomy (SG) has rapidly become the most commonly performed bariatric procedure in the United States as well as other countries, with approximately 120,000 procedures being performed annually in the United States. Reoperative interventions after SG have become more prevalent in the past few years since the initial development of SG as a primary operation. Given the expected rapid growth of these reinterventions, an expert consensus conference was held with some of the most experienced bariatric surgeons in the world to better understand, discuss, and provide consensus on the reasons, indications, contraindications, and surgical options for nonresponders and complicated SG operations.

OBJECTIVES

Provide consensus-based best practice guidelines regarding the performance of reinterventions after failed or complicated SG in patients with obesity, using expert opinion by organizing a consensus meeting of experts and evaluating the current literature.

SETTING

The meeting was held in Boca Raton, Florida on February 18, 2017.

METHODS

The panel of 32 expert bariatric surgeons representing 12 countries and major regions of the world and all 6 populated continents identified 54 questions for consensus. Questions encompassed patient selection, indications, contraindications, surgical technique, prevention and management of weight regain, and short- and long-term complications after SG. Responses were calculated and defined as achieving consensus (≥70% agreement) or no consensus (<70% agreement). The current available literature was extensively reviewed for each topic in question and proposed to the panel.

RESULTS

Full consensus was obtained for the essential aspects of indications and contraindications, surgical technique, management, and prevention of complications. Consensus was achieved for 35 of 54 key questions. Highlights include consensus recommendations regarding technique in reoperation, management of GERD and Barrett's esophagus after SG, and surgical options for poor initial weight loss. No consensus was reached on topics, such as management of chronic proximal fistula after SG.

CONCLUSIONS

This first international expert meeting provides 35 statements and recommendations for a clinical consensus guideline regarding standardization of indications, contraindications, surgical options, and surgical techniques when reoperating on patients who underwent a failed or complicated SG. To our knowledge, the present consensus report represents the first document that defines best practice guidelines for the performance of reinterventions after failed or complicated SG.

Completion Gastrectomy with Esophagojejunostomy for Management of Complications of Benign Foregut Surgery

BACKGROUND

With the worldwide epidemic of obesity, an increasing number of bariatric operations and antireflux fundoplications are being performed. Despite low morbidity of the primary foregut surgery, completion gastrectomy may be necessary as a definitive procedure for complications of prior foregut surgery; however, the literature evaluating outcomes after completion gastrectomy with esophagojejunostomy (EJ) for benign diseases is limited. We present our experience of completion gastrectomy with Roux-en-Y EJ in the setting of benign disease at a single tertiary center.

METHODS AND PROCEDURES

All patients who underwent total, proximal, or completion gastrectomy with EJ for complications of benign foregut surgery from January 2006 to December 2015 were retrospectively identified. All cancer operations were excluded.

RESULTS

There were 23 patients who underwent gastrectomy with EJ (13 laparoscopic EJ [LEJ] and 10 open EJ). The index operations included 12 antireflux, 9 bariatric, and 2 peptic ulcer disease surgeries. Seventy-eight percent of patients had surgical or endoscopic interventions before EJ, with a median of one prior intervention and a median interval from the index operation to EJ of 25 months (interquartile range 9-87). The 30-day perioperative complication rate was 30% with 17% classified being major (Clavien-Dindo ≥ III) and no 30-day perioperative mortality. Comparing laparoscopic and open approaches showed similar operative times, estimated blood loss, and overall complication rate. LEJ was associated with a shorter length of stay (LOS) (P < .001), fewer postoperative ICU days (P = .002), fewer 6-month complication rates (P < .007), and decreased readmission rate (P = .024).

CONCLUSION

Our series demonstrates that EJ is a reasonable option for reoperative foregut surgery. The laparoscopic approach appears to be associated with decreased LOS and readmissions.
