Research progress of mesh-related visceral complications after tension-free inguinal hernia repair / 中华消化外科杂志

Mesh-related visceral complications caused by mesh erosion after tension-free inguinal hernia repair are one kind of rare long-term complications, but they are easily neglected. Interval time from initial hernia repair to mesh-related visceral complications by preperitoneal and laparoscopic repair is short. Rutkow and transabdominal preperitoneal repair have the highest reported rate. Lichtenstein has the longest interval time and the lowest reported rate. The most frequently eroded organs are sigmoid colon, bladder and small intestine. The common clinical manifestations of sigmoid colon erosion are hematochezia, abdominal wall fistula and colitis, hematuria and recurrent urinary tract infection in bladder erosion cases, intestinal obstruction and abdominal wall fistula in intestinal erosion case, sigmoid-bladder fistula and intestinal-bladder fistula in multiple organ erosion cases. Resection or repair of corresponding organs with mesh removal have good efficacies in most patients. The authors summarize and analyze researches on mesh-related visceral complications after tension-free inguinal hernia repair from 1994 to 2021, review their advances, in order to raise awareness of such complications in clinicians.

Diagnosis and treatment of primary retroperitoneal liposarcoma / 中华普通外科杂志

Objective The aim of this study is to analyze the clinical characteristics,diagnosis,treatment and prognosis factors of primary retroperitoneal liposarcoma.Methods We retrospectively analyzed 44 patients diagnosed with primary retroperitoneal liposarcoma that confirmed by pathology from Jan 2008 to Jun 2018 at the Department of General Surgery,Shengjing Hospital,China Medical University.Results The 44 patients consist of 19 males and 25 females.the clinical manifestations were abdominal mass,abdominal distension and abdominal pain.Asymptomatic patients were mainly found through physical examination.The main preoperative examination method was CT,and its accuracy rate was 75％.The most common pathological type was well-differentiated liposarcoma.The recurrence rate is 82％,and 24 (55％) patients died from tumor recurrence,2 patients died of other unrelated diseases.Conclusions Primary retroperitoneal liposarcoma is difficult to be diagnosed at early stage.CT is the main examination method.Complete surgical resection is the main treatment for primary or recurrent patients.This disease is prone to relapse and the prognosis is poor.
