Intussusception, a Plausible Cause of the Candy Cane Syndrome (Roux Syndrome): Known for a Century-Still a Frequently Missed Cause of Pain After Roux-en-Y Gastric Bypass

Magnet and wire remodeling for the treatment of candy cane syndrome: first case series of a new approach (with video)

BACKGROUND AND AIMS

Candy cane syndrome (CCS) is an adverse event (AE) from gastrectomy or gastric bypass and end-to-side anastomosis to a jejunal loop. Preferential passage of food to the blind loop induces early satiety, pain, and regurgitation. An endoscopic device that combines 2 magnets and a self-retractable wire was designed to perform progressive septotomy with marsupialization. We evaluated the clinical safety and efficacy of this treatment in CCS.

METHODS

Consecutive patients presenting with symptoms associated with CCS after gastrectomy or Roux-en-Y gastric bypass were treated with the MAGUS (Magnetic Gastrointestinal Universal Septotome) system. Weight, dysphagia, pain scores, 12-item Short Form Survey quality of life physical and mental scores, GERD Health-Related Quality of Life, and Eckardt score were measured at baseline and 1 and 3 months postprocedure. Satisfaction with therapy and AEs were monitored during follow-up.

RESULTS

Fourteen consecutive patients with CCS were enrolled in the study. Thirteen MAGUS systems migrated within 28 days after achieving uneventful complete septotomy. In 1 patient the magnet had to be collected from the right-sided colon after 1 month. Treatment was completed in a single endoscopy session. Dysphagia score (2 [1-3] vs 1 [1-1], P = .02), pain score (7 [6-8] vs 1 [0-1], P = .002), Eckardt score (5 [3-8] vs 1 [0-2], P = .002), GERD Health-Related Quality of Life score (37 [29-45] vs 8 [6-23], P = .002), and quality of life physical and mental scores were all significantly improved at 3 months. No device or procedure-related serious AEs were observed. One patient died during follow-up from evolution of oncologic disease.

CONCLUSIONS

Endoluminal septotomy using a retractable wire and magnet system in CCS is feasible and safe, with rapid improvement of symptoms. (Clinical trial registration number: NCT04480216.).

The clinical effectiveness of the method by establishing a proximal jejunum pouch after laparoscopic total gastrectomy: A propensity score-based analysis

BACKGROUND

In this study, we propose an improved Roux-en-Y (RY) surgical method by constructing a proximal jejunum pouch (PP-RY). Postoperative results were evaluated among patients with gastric cancer who underwent PP-RY and standard RY anastomosis.

METHODS

The clinical data of patients with gastric cancer who underwent laparoscopic total gastrectomy (LTG) in our center from May 2019 to May 2020 were collected retrospectively. We compared the short-term results of patients in the PP-RY and RY groups using 1:1 propensity score matching (PSM).

RESULTS

A total of 317 patients were selected, including those who received RY (n = 249) or PP-RY (n = 68) after LTG. After PSM, both groups had a sample size of 68. During the one-year follow-up period, the incidences of postoperative dumping syndrome (5.6%) and reflux esophagitis (14.8%) were significantly lower in the PP-RY group (P = 0.001 and P = 0.010, respectively). Weight loss (6.5 ± 2.0 kg) and albumin decrease (0.2 ± 0.1 g/dl) were significantly lower (P = 0.038 and P < 0.001, respectively), and the prognostic nutritional index (PNI) was significantly higher in the PP-RY group (P = 0.009). In the QLQ-C30 scale, the degree of anorexia in the PP-RY group was significantly lower than that in the RY group (P＜0.05). In the QLQ-STO22 scale, chest and abdomen pain, dietary restriction, and anxiety were significantly lower in the PP-RY group (all P＜0.05).

CONCLUSION

PP-RY can lead to obvious improvements in nutritional status, reduce short-term complications, and improve quality of life (QoL) for patients after LTG.

Revision of a Previous Capella Bypass due to dysphagia, GERD and Candy Cane Syndrome

BACKGROUND

Capella ringed gastric bypass is a technical variant of gastric bypass which seeks to improve long-term outcomes with a greater restriction. Frequent complications are due to the band, due to its inclusion or slippage, without being able to reject others. Our purpose is to present the video of a revisional bariatric surgery made by laparoscopic approach in a patient with a previous open retrogastric retrocolic Capella gastric bypass.

MATERIALS AND METHODS

The patient presents dysphagia, gastroesophagic reflux disease (GERD), and pain, with a BMI of 36 kg/m². Her supplementary tests show a hiatal hernia, GERD, and a Candy Cane Syndrome. The surgery was difficult due to multiple adhesions. Hiatal hernia was repaired and pillars were closed. The band was visualized intraoperatively close to the gastrojejunal anastomosis, although the high endoscopy did not detect neither stenosis nor difficulty of passage to the gastric pouch. It showed the retrogastric gastrojejunal anastomosis with a normal food loop and a 15-cm widened blind loop (Candy Cane Syndrome), which was resected.

RESULTS

She had a left pneumonia and damage in left hepatic lobe (LHL). She was discharged after antibiotic treatment for 7 days. The patient has improved clinically, without dysphagia nor GERD. Her current BMI is 29.8 kg/m².

CONCLUSIONS

In conclusion, bariatric revisional surgery can lead to serious complications, but it is justified in patients with poor quality of life. A ringed retrocolic retrogastric bypass poses more difficulties in revisional procedures. It is mandatory to know which technique was performed before. The duration of the procedure can result in more complications like liver damage.
