Effect on iron deficiency anemia of laparoscopic repair of large paraesophageal hernias

Patients with iron deficiency anemia sometimes have a large paraesophageal hernia and no other explanation for their chronic blood loss. The management of these patients can be a dilemma, especially when the hernia is otherwise asymptomatic. We aimed to determine whether a laparoscopic repair of the hernia could cure the anemia. We reviewed a consecutive series of 11 cases of iron deficiency anemia associated with a large paraesophageal hernia, many without associated linear gastric erosions, managed by laparoscopic repair and fundoplication. There was one conversion in a patient with dense adhesions from previous upper abdominal surgery. Another patient required a laparoscopic reoperation for an early recurrence. Major morbidity occurred in three patients and there was no mortality. There was no recurrence of anemia after a median follow-up of more than 2 years. Iron deficiency anemia in association with a large paraesophageal hernia can be treated by laparoscopic repair with acceptable morbidity and minimal mortality. The complications of a large paraesophageal hernia are also prevented.     

Prenatal management of congenital diaphragmatic hernia

Recently, two randomized controlled, prospective trials, the Tracheal Occlusion to Accelerate Lung Growth (TOTAL) trials, reported the outcomes on fetal endoluminal tracheal occlusion (FETO) for isolated left congenital diaphragmatic hernia (CDH). FETO significantly improved outcomes for severe hypoplasia. The effect in moderate cases, where the balloon was inserted later in pregnancy, did not reach significance. In a pooled analysis investigating the effect of the heterogeneity of the treatment effect by the time point of occlusion and severity, the difference may be explained by a difference in the duration of occlusion. Nevertheless, FETO carries a significant risk of preterm birth. The primary objective of this review is to provide an overview of the rationale for fetal intervention in CDH and the results of the randomized trials. The secondary objective is to discuss the technical aspects of FETO. Finally, recent developments of potential alternative fetal approaches will be highlighted.     

Reoperation with laparoscopic mesh repair for recurrent lumbar hernia due to iliac crest bone harvest

Previous reports have described laparoscopic mesh repair for lumbar hernia due to iliac crest bone harvest, but there have been no reports of reoperation with laparoscopic mesh repair for recurrent cases after laparoscopic mesh repair. Here, we describe the case of a 72-year-old Japanese woman with lumbar hernia recurrence 6 years after laparoscopic mesh repair for lumbar hernia due to iliac crest bone harvest. We performed a successful reoperation with laparoscopic mesh repair. Laparoscopic surgery should be considered to elucidate the mechanism of recurrence, previous mesh position, and the area that must be covered to prevent recurrence again.     

Rare presentation of De Garengeot hernia treated by transabdominal preperitoneal hernia repair: A case report

We present a rare case of De Garengeot hernia treated with simultaneous laparoscopic appendectomy and transabdominal preperitoneal hernia repair. Our patient was an 85-year-old man with a bulging mass in the right groin. De Garengeot hernia was observed on contrast-enhanced CT. Urgent laparoscopy showed the distal part of the appendix passing through a right-sided femoral hernia. Laparoscopic appendectomy was performed, followed by transabdominal preperitoneal repair of the femoral hernia. Pathological examination revealed ischemic necrosis of the appendix. The patient's postoperative recovery was uneventful.     

Multifactor study of efficacy and recurrence in laparoscopic surgery for inguinal hernia

BACKGROUNDInguinal hernia is a common clinical manifestation in children with a low self-healing rate. AIMTo determine the effect of laparoscopic surgery on indirect inguinal hernia and the risk factors for postoperative recurrence and to provide a reference for the clinical treatment and prevention of recurrence.METHODSWe selected 360 children who underwent laparoscopic high ligation in our hospital as the laparoscopic group and 120 patients treated for inguinal hernia with conventional surgery as the control group. The operation time, blood loss, incision length, hospitalization time, total hospitalization cost and surgical complications were compared between the two groups. According to telephone follow-up or return visits, the children who had recurrence within 2 years after the operation in the laparoscopic group were analyzed, and the laparoscopic high ligation hernia sac level was analyzed by the logistic multifactor method. Ligation was used to treat recurrence in children with inguinal hernia.RESULTSThe operation time, blood loss, length of incision, and length of hospital stay in the laparoscopic group were lower than those in the control group (P < 0.05). The total hospitalization cost in the laparoscopic group was higher than that in the control group (P < 0.05). The operative complication rate was 1.67% lower than that in the control group (12.50%) (P < 0.05). In 360 children with laparoscopic high ligation of the hernia sac, 14 patients had recurrence within 2 years after surgery. After analysis, 14 cases in the recurrence group did not recur. The preoperative incarceration rate, inner ring diameter, ligature use and age difference were statistically significant (P < 0.05). According to logistic regression multivariate analysis, an inner ring diameter ≥ 1.0 cm, the use of an absorbable ligature line and age > 3 years increased the risk of postoperative recurrence in children with inguinal hernia after laparoscopic high ligation of the hernia sac (P < 0.05). CONCLUSIONLaparoscopic surgery for indirect inguinal hernia in children has the advantages of low trauma and a rapid postoperative recovery. An inner ring diameter ≥ 1.0 cm, the use of absorbable ligature, and age > 3 years may increase the risk of recurrence after laparoscopic high ligation of the hernia sac.

Female Gender and Diabetes Mellitus Increase the Risk of Recurrence after Laparoscopic Incisional Hernia Repair

Background

Laparoscopic hernia repair is used widely for the repair of incisional hernias. Few case studies have focussed on purely ‘incisional’ hernias. This multicentre series represents a collaborative effort and employed statistical analyses to provide insight into the factors predisposing to recurrence of incisional hernia after laparoscopic repair. A specific hypothesis (ie, laterality of hernias as well as proximity to the xyphoid process and pubic symphysis predisposes to recurrence) was also tested.

Methods

This was a retrospective study of all laparoscopic incisional hernias undertaken in six centres from 1 January 2004 to 31 December 2010. It comprised a comprehensive review of case notes and a follow-up using a structured telephone questionnaire. Patient demographics, previous medical/surgical history, surgical procedure, postoperative recovery, and perceived effect on quality of life were recorded. Repairs undertaken for primary ventral hernias were excluded. A logistic regression analysis was then fitted with recurrence as the primary outcome.

Results

A total of 186 cases (91 females) were identified. Median follow-up was 42 months. Telephone interviews were answered by 115/186 (62%) of subjects. Logistic regression analyses suggested that only female sex (odds ratio (OR) 3.53; 95% confidence interval (CI) 1.39–8.97) and diabetes mellitus (3.54; 1–12.56) significantly increased the risk of recurrence. Position of the defect had no statistical effect.

Conclusions

These data suggest an increased risk of recurrence after laparoscopic incisional hernia repair in females and subjects with diabetes mellitus. These data will help inform surgeons and patients when considering laparoscopic management of incisional hernias. We recommend a centrally hosted, prospectively maintained national/international database to carry out additional research.     

Small bowel obstruction via herniation through an iatrogenic defect of the falciform ligament following laparoscopic cholecystectomy

Internal herniation of the small bowel through a defect in the falciform ligament and subsequent small bowel obstruction is exceedingly rare with the majority of previous cases being attributed to congenital abnormalities. As laparoscopic techniques approach the forefront of modern surgery, an iatrogenic source for a falciform ligament defect has emerged over the last decade. In this case, a 50-year-old patient presented with signs of acute small bowel obstruction 10 days after a laparoscopic cholecystectomy. On diagnostic laparoscopy, part of the jejunum was found to have herniated through an opening in the falciform ligament. This was likely to have been caused by trauma during the cholecystectomy. Following relief of the obstruction, the defect was closed with polyglactin sutures.
