Hem-o-Lok clip migration into the duodenum after laparoscopic digestive surgery: a systematic review

Hem-o-lok clip migration to duodenal bulb post-cholecystectomy: A case report

BACKGROUND

Hem-o-lok clips are typically used to control the cystic duct and vessels during laparoscopic cholecystectomy (LC) and common bile duct exploration for stones in the bile duct and gallbladder. Here, we report a unique example of Hem-o-lok clip movement towards the duodenal bulb after LC, appearing as a submucosal tumor (SMT). Additionally, we provide initial evidence of gradual and evolving endoscopic manifestations of Hem-o-lok clip migration to the duodenal bulb wall and review the available literature.

CASE SUMMARY

A 72-year-old man underwent LC for gallstones, and Hem-o-lok clips were used to ligate both the cystic duct and cystic artery. Esophagogastroduodenoscopy (EGD) 2 years later revealed an SMT-like lesion in the duodenal bulb. Due to the symptomatology, the clinical examination did not reveal any major abnormalities, and the patient was followed up as an outpatient. A repeat EGD performed 5 months later revealed an SMT-like lesion in the duodenal bulb with raised edges and a central depression. A third EGD was conducted, during which a Hem-o-lok clip was discovered connected to the front side of the duodenum. The clip was extracted easily using biopsy forceps, and no complications occurred. Two months after the fourth EGD, the scar was surrounded by normal mucosa.

CONCLUSION

Clinicians should be aware of potential post-LC complications. Hem-o-lok clips should be removed if symptomatic.

Hem-o-lok clip migration to the common bile duct after laparoscopic common bile duct exploration: A case report

BACKGROUND

Laparoscopic cholecystectomy (LC) and laparoscopic common bile duct exploration (LCBDE) has been widely used for management of gallbladder and common bile duct (CBD) stones. Post-operative clip migration is a rare complication of laparoscopic biliary surgery, which can serve as a nidus for stone formation and cause recurrent cholangitis.

CASE SUMMARY

A 59-year-old female was admitted to hospital because of fever and acute right upper abdominal pain. She has a history of LC and had a LCBDE surgery 2 mo ago. Physical examination revealed tenderness in the upper quadrant of right abdomen. Computed tomography scan demonstrated a high-density shadow at the distal CBD, which was considered as migrated clips. The speculation was confirmed by endoscopic retrograde cholangiopancreatography examination, and two displaced Hem-o-lok clips were removed with a stone basket. No fever or abdominal pain presented after the operation. In addition to the case report, literature regarding surgical clip migration after laparoscopic biliary surgery was reviewed and discussed.

CONCLUSION

Incidence of postoperative clip migration may be reduced by using clips properly and correctly; however, new methods should be explored to occlude cystic duct and vessels. If a patient with a past history of LC or LCBDE presents with features of sepsis and recurrent upper quadrant pain, clip migration must be considered as one of the differential diagnosis.

Migration of non-absorbable polymer clips in hepato-biliary-pancreatic surgery: a report of four cases

Background

Ligation clips are used for vessel or tissue ligation in surgery. Although previous reports have described the migration of metallic clips after hepato-biliary-pancreatic surgery, very few reports have described the migration of non-absorbable polymer clips (NAPCs: Hem-o-Lok).

Case presentation

We present 4 cases of NAPC migration that occurred after laparoscopic surgery. Case 1 was an 81-year-old woman that had undergone a laparoscopic right hemihepatectomy for an intrahepatic bile duct cyst adenocarcinoma at the age of 79 years. Two years after the operation, she underwent an upper gastrointestinal endoscopy to investigate epigastric pain. The endoscopy showed NAPCs lodged at the anterior side of the duodenal bulb. Case 2 was an 80-year-old man that had undergone a laparoscopic cholecystectomy for choledocholithiasis at the age of 77 years. Three years after the operation, follow-up computed tomography and magnetic resonance cholangiopancreatography (MRCP) imaging indicated a mass in the upper bile duct. After a laparoscopic bile duct resection and reconstruction, an NAPC was found inside the inflammatory pseudotumor. Case 3 was a 63-year-old man that had undergone laparoscopic liver S4b and S5 resections and lymph node dissection for gallbladder cancer. Three months after the operation, follow-up MRCP imaging suggested a bile duct stenosis. An endoscopic retrograde cholangiopancreatography (ERCP) was performed, and an NAPC was found inside the bile duct. Case 4 was a 74-year-old man that had undergone a laparoscopic S5 segmentectomy, S7 partial liver resection, and cholecystectomy for liver metastasis of lung cancer and cholelithiasis. A trans-cystic drainage tube was inserted, and it was ligated and fixed with NAPCs. Three months after the operation, follow-up MRCP imaging showed common bile duct stones (CBDS). An ERCP was performed, and two NAPCs were found with the CBDS.

Conclusions

Few previous reports have described complications due to NAPC migration after hepato-biliary-pancreatic surgery. However, with the widespread use of NAPC, postoperative complications due to NAPC migration are expected to increase in the near future. The differential diagnosis of complications should include potential NAPC migration in patients that have undergone laparoscopic surgery.

Mesenteric closure with polymer-ligating clips after right colectomy with complete mesocolic excision for cancer and mesentery-based ileocolic resection for Crohn's disease

Mesenteric closure following right colectomy remains controversial and, following the advent of laparoscopic surgery, many surgeons do not routinely close the mesentery after colorectal resection. Nevertheless, especially after the introduction of operations such as right colectomy with complete mesocolic excision and ileocolic resections with extensive mesentery removal for Crohn's disease, the wide mesenteric defect resulting from the dissections can certainly expose the patients to complications such as internal hernias or volvuli. In general, mesenteric closure requires intracorporeal suturing. We describe a simple technique for the closure of the mesentery after surgical resection using polymer-ligating clips. This novel technique seems to minimize the time, effort and risk inherent to the procedure, even after large mesenteric excisions.
