Background  

The incidence of afferent loop obstruction after gastrectomy with Roux-en-Y reconstruction has not yet been reported. The aim of this study was to elucidate the incidence of afferent loop obstruction after distal gastrectomy with Roux-en-Y reconstruction performed through an open approach.     

Different Features of Complications with Billroth-I and Roux-en-Y Reconstruction After Laparoscopy-Assisted Distal Gastrectomy

Background

This study investigated differences in the features of postoperative complications between Billroth-I (B-I) and Roux-en-Y (R-Y) reconstructions after laparoscopy-assisted distal gastrectomy (LADG) for early gastric cancer.

Material and methods

The study included 424 patients who underwent LADG for cT1, cN0 gastric cancer. Patient characteristics, surgical outcomes, postoperative complications including severity assessment using the Clavien?CDindo classification, and risk factors related to postoperative complications were analyzed.

Results

B-I and R-Y were performed in 329 and 95 patients, respectively. Total time in hospital was longer in R-Y (15.2?±?10.5 days) than in B-I (12.8?±?6.4 days; P?=?0.034). The incidence of severe complications was higher in R-Y (13.7%) than in B-I (5.2%; P?=?0.009). Three cases of internal hernia and three cases of duodenal stump leakage were observed in R-Y. Univariate analysis revealed the method of reconstruction was a risk factor for severe postoperative complications after LADG (P?=?0.006).

Conclusions

The features of postoperative complications are quite different between B-I and R-Y after LADG. Complications after R-Y were more severe than those after B-I. To avoid these severe complications in R-Y, it is necessary to understand these different features.     

Effectiveness of Roux-en-Y Reconstruction After Distal Gastrectomy Based on an Assessment of Biliary Kinetics

Purpose: To evaluate the efficiency of Roux-en-Y reconstruction (RY) after distal gastrectomy we compared postoperative physiological functions and disorders among patients who underwent RY, conventional Billroth I reconstruction (BI), or Billroth II reconstruction (BII). Methods: The subjects were 91 patients who had undergone distal gastrectomy for gastric cancer more than 1 month earlier. To examine the severity of gastroesophageal reflux, acid reflux and alkali reflux were assessed, and to examine the severity of duodenal reflux into the remnant stomach, biliary scintigraphy was performed. The degree of inflammation in the esophagus and remnant stomach was examined by endoscopy. Questionnaires on postoperative complaints were sent out to the patients to determine how serious their reflux symptoms were. Results: Both acid and alkali reflux were mild in the RY group. Biliary reflux into the remnant stomach, as assessed by biliary scintigraphy, was significantly less severe in the RY group than in the BI and BII groups. Endoscopy showed that inflammation of the lower esophagus and remnant stomach was much less severe in the RY group than in the BI and BII groups. According to the questionnaire survey, none of the patients in the RY group reported any reflux symptoms. Conclusions: In this series, RY was found to be a superior reconstruction method after distal gastrectomy since it was rarely accompanied by the reflux of duodenal juice into the remnant stomach or gastric reflux into the lower esophagus.

Randomized Controlled Trial of Roux-en-Y Versus Rho-Shaped-Roux-en-Y Reconstruction After Distal Gastrectomy for Gastric Cancer

Background  The main advantage of the Roux-en-Y (RY) operation is that it prevents bile and pancreatic juice from reaching the gastric mucosa, although the gastrojejunostomy may cause functional delayed gastric emptying (DGE), known as RY stasis syndrome. Rho-shaped Roux-en-Y reconstruction (rRY), an RY reconstruction with a rho-shaped anastomosis, is an established operation that has been found to be effective in preventing DGE. Methods  We conducted the randomized trial of RY versus rRY reconstruction after gastric cancer resection. The primary endpoint was the frequency of DGE, and secondary endpoints were the length of postoperative hospital stay, morbidity, and nutritional status. Seventy patients were enrolled, with 35 in each group. Results  The incidences of postoperative mortality and morbidity did not differ significantly between the two groups. There were no significant differences in nutritional status between the two groups after discharge. Delayed gastric emptying occurred in two patients (6%) in the RY group and four patients (11%) in the rRY group (P = 0.67). Logistic regression analysis revealed that truncal vagotomy was significantly associated with DGE inhibition. Conclusions  Our findings showed that RY reconstruction after gastrectomy may be as simple and sufficient as conventional reconstruction.

Comparison of the Invasiveness Between Reduced-Port Laparoscopy-Assisted Distal Gastrectomy and Conventional Laparoscopy-Assisted Distal Gastrectomy

It is unknown whether reduced-port gastrectomy has a less invasive nature than conventional laparoscopy-assisted distal gastrectomy (C-LADG). So we compared 30 cases of dual-port laparoscopy-assisted distal gastrectomy (DP-LADG; using an umbilical port plus a right flank 5-mm port) as a reduced-port gastrectomy with 30 cases of C-LADG alternately performed by a single surgeon. No significant differences were observed in blood loss, intraoperative complications, the number of dissected lymph nodes, postoperative complications, the day of first defecation, analgesic agents required, changes in body temperature, heart rate, white blood cell count, serum albumin level, or lymphocyte count between the 2 groups. The amounts of oral intake in the DP-LADG group were significantly higher on postoperative days 9 and 10. We concluded that the amount of oral intake in the DP-LADG group was superior to that in the C-LADG group; however, no other evidence of DP-LADG being less invasive than C-LADG was obtained.     

Laparoscopic Roux-en-Y Gastric Bypass with Subtotal Gastrectomy

Laparoscopic gastric bypass is a common procedure for morbid obesity. After gastric bypass, the distal stomach is unavailable for surveillance. When a suspicious distal gastric lesion is present preoperatively, a distal subtotal gastrectomy may be needed. Herein we describe such a case performed laparoscopically. Laparoscopic gastric bypass with subtotal gastrectomy for morbid obesity should be considered for patients with suspicious distal gastric lesions.

Comparison of Outcomes Between Laparoscopic Roux-en-Y Gastric Bypass and Sleeve Gastrectomy in a Lebanese Bariatric Surgical Practice

Purpose

Long-term studies on the outcomes of bariatric surgery are still limited in the Middle East. The aim of this study is to compare the outcomes of laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG) up to 5 years of follow-up.

Materials and Methods

A retrospective analysis of patients who underwent LRYGB and LSG was performed. The primary outcome was weight loss. Postoperative complications, operative time, and hospital length of stay were secondary outcomes.

Results

Four hundred patients underwent primary LSG and 175 patients underwent LRYGB between 2008 and 2013. Follow-up rates at 5 years were around 60%. Percent total weight loss was similar after 3, 4, and 5 years in both groups, averaging around 28%. Mean percentage of excess weight loss (%EWL) at 5 years was 72.0 ± 31.0% in the LSG group vs. 63.0 ± 21.0% in the LRYGB group (p = 0.03). Patients undergoing LRYGB had a significantly longer operative time as well as a longer hospital stay. No significant difference was found in the rates of short- and long-term complications between the two groups. However, patients undergoing LRYGB were more likely to develop small intestinal obstruction and iron-deficiency anemia.

Conclusions

Both LSG and LRYGB result in satisfactory weight loss within 5 years. Patients’ comorbidities and potential risks must be included in the choice of the appropriate bariatric procedure. LSG appears to give durable weight loss with less risk of major long-term complications.

     

Laparoscopic Distal Gastrectomy is Feasible in Very Elderly Patients as Compared with Open Distal Gastrectomy

ABSTRACT

Laparoscopic gastrectomy was shown to be feasible even in elderly patients in many retrospective case-controlled studies. However, the definition of elderly differed among those studies, such as an age of 65, 70, or 75 years or older. This study was conducted to elucidate the advantages of laparoscopic distal gastrectomy (LDG) in very elderly (≥80 years) patients, and comprised 70 patients, 45 of whom underwent LDG and 25 underwent open distal gastrectomy (ODG) between 2004 and September 2016. LDG had significantly less estimated blood loss (p < .01), earlier flatus (p < .01), earlier food intake (p < .01), and shorter hospitalization (p < .01) as compared with ODG. No significant difference between LDG and ODG was found in the incidence of postoperative surgical complications (p = .40), although LDG tended to reduce overall and medical postoperative complications (p = .11 and .09, respectively). LDG might be a feasible, beneficial treatment with good short-term outcomes in very elderly patients with gastric cancer.     

Risk Factors for Prolonged Length of Hospital Stay and Readmissions After Laparoscopic Sleeve Gastrectomy and Laparoscopic Roux-en-Y Gastric Bypass

Background

Laparoscopic sleeve gastrectomy (LSG) and laparoscopic gastric bypass (LRYGB) are most commonly performed bariatric procedures. Laparoscopic approach and enhanced recovery after surgery (ERAS) protocols managed to decrease length of hospital and morbidity. However, there are patients in whom, despite adherence to the protocol, the length of stay (LOS) remains longer than targeted. This study aimed to assess potential risk factors for prolonged LOS and readmissions.

Methods

The study was a prospective observation with a post-hoc analysis of bariatric patients in a tertiary referral university teaching hospital. Inclusion criteria were undergoing laparoscopic bariatric surgery. Exclusion criteria were occurrence of perioperative complications, prior bariatric procedures, and lack of necessary data. The primary endpoints were the evaluations of risk factors for prolonged LOS and readmissions.

Results

Median LOS was 3 (2–4) days. LOS > 3 days occurred in 145 (29.47%) patients, 79 after LSG (25.82%) and 66 after LRYGB (35.48%; p = 0.008). Factors significantly prolonging LOS were low oral fluid intake, high intravenous volume of fluids administered on POD0, and every additional 50 km distance from habitual residence to bariatric center. The risk of hospital readmission rises with occurrence of intraoperative adverse events and low oral fluid intake on the day of surgery on.

Conclusions

Risk factors for prolonged LOS are low oral fluid intake, high intravenous volume of fluids administered on POD0, and every additional 50 km distance from habitual residence. Risk factors for hospital readmission are intraoperative adverse events and low oral fluid intake on the day of surgery.

     

Laparoscopic Total Gastrectomy with Roux-Y Esophagojejunostomy for Chronic Gastric Fistula After Laparoscopic Sleeve Gastrectomy

Laparoscopic sleeve gastrectomy is a restrictive operation with hormonal elements that is rapidly gaining popularity. The most feared complication of the procedure is a staple line leak. The treatment of staple line leakage depends on timing and clinical and anatomical considerations. If leakage persists and transforms into a chronic fistula, a definitive surgical procedure is required. In cases where the fistula originates close to the esophagogastric junction, the surgical possibilities are limited and one treatment option is total gastrectomy with esophagojejunal anastomosis. We report a case series of four patients with chronic fistulae, who failed conservative treatment and required total gastrectomy. Their average length of hospital stay was 8.7 days (range, 5–15 days), without conversions, leaks, or other complications. In experienced hands, total gastrectomy is feasible by laparoscopic techniques and should be performed soon after the fistula is established.     

Comparison of Billroth I and Roux-en-Y Reconstruction after Distal Gastrectomy for Gastric Cancer: One-year Postoperative Effects Assessed by a Multi-institutional RCT

Purpose

This randomized, controlled trial evaluated the clinical efficacy of Billroth I (BI) and Roux-en-Y (RY) reconstruction at 1 year after distal gastrectomy for gastric cancer.

Methods

The primary end point was the amount of body weight lost at 1 postoperative year, and secondary end points included other items related to nutritional status such as serum albumin and lymphocyte count, as well as endoscopic examination findings of the remnant stomach and esophagus. Of the 332 patients enrolled, 163 were assigned to the BI group and 169 were randomized to the RY group.

Results

The loss in body weight 1 year after surgery did not differ significantly between the BI and RY groups (9.1 % and 9.7 %, respectively, p = 0.39). There were no significant differences in other aspects of nutritional status between the 2 groups. Endoscopic examination 1 year after gastrectomy showed reflux esophagitis in 26 patients (17 %) in the BI group versus 10 patients (6 %) in the RY group (p = 0.0037), while remnant gastritis was observed in 71 patients (46 %) in the BI group versus 44 patients (28 %) in the RY group (p = 0.0013); differences were significant for both conditions. Multivariable analysis showed that the only reconstruction was the independently associated factor with the incidence of reflux esophagitis.

Conclusions

RY reconstruction was not superior to BI in terms of body weight change or other aspects of nutritional status at 1 year after surgery, although RY more effectively prevented reflux esophagitis and remnant gastritis after distal gastrectomy.     

Gastric Leak After Laparoscopic Sleeve Gastrectomy

Sleeve gastrectomy is a recently developed technique for treating morbid obesity. Since it is a simple procedure, the number of surgeons using it has grown in recent years. The patients who present fistulas after surgery often undergo a harrowing postoperative period as well as increased morbidity and mortality. Our aim was to assess the incidence, causes, diagnosis, management, and prevention of leaks after sleeve gastrectomy.

Mechanical-Stapled Versus Hand-Sutured Anastomoses in Billroth-I Reconstruction with Distal Gastrectomy

PURPOSE: In June 2000, we started performing mechanical-stapled anastomosis (MSA) for Billroth-I reconstruction (B-I) in distal gastrectomy. Thus, we performed a retrospective study to compare the clinical outcome of MSA and conventional hand-sutured anastomosis (HA). METHODS: We evaluated 103 patients who underwent a B-I reconstruction. The data we collected included operative time, operative blood loss, time until oral intake, postoperative hospital stay, and anastomotic and general complications. We also examined the remnant stomach by endoscopy and classified it according to the Residue, Gastritis, Bile (RGB) criteria. RESULTS: The operative time was significantly shorter with MSA than with HA, but there were no other significant differences between the two groups. The RGB classification showed that there was more residual stomach content after MSA than after HA. The incidence of gastritis and bile reflux was not significantly different between the two procedures. CONCLUSION: The operative time for B-I reconstruction with distal gastrectomy was significantly shorter with MSA than with HA. While there were no significant disadvantages in the incidence of complications associated with MSA compared with HA, MSA resulted in more residue in the remnant stomach. The findings of this study showed the advantages and disadvantages of MSA, and suggest that MSA and HA are equivalent as anastomotic procedures in B-I reconstruction.
