Inguinal hernia repair in Spain. A population-based study of 263,283 patients: factors associated with the choice of laparoscopic approach.

PURPOSE: The objective of this study is to evaluate the laparoscopic inguinal hernia repair (IHR) rate in Spain and identify the factors associated with the choice of this surgical approach. METHODS: A retrospective cohort study of 263,283 patients who underwent IHR from January 2016 to December 2018 was conducted. Data were extracted from the Spanish Minimum Basic Data Set (MBDS) of the Health Ministry database. The primary outcome was laparoscopic (LAP) rate utilization. Univariate analysis and multivariable logistic regression analysis were performed to identify factors associated with LAP-IHR. RESULTS: Only 5.7% (15,059) patients underwent LAP-IHR, whereas the remnant 94.3% (248,224 patients) underwent open repair. High variability in the LAP-IHR rate across the country was observed; ranged between provinces from 0 to 19.7%, for a unilateral hernia, and between 0 to 57.4% in the case of bilateral hernias. On multivariate logistic regression analysis, the patient place of residence was the most remarkable factor associated with the likelihood of receiving LAP-IHR (OR 4.96; p < 0.001). There were also significant differences favoring LAP-IHR for bilateral operation (OR 4.596; p < 0.001), insurance coverage (OR 4.439, p < 0.001) and self-pay patients (OR 2.317; p < 0.001), as well as a recurrent hernia (OR 1.780; p < 0.001), age younger than 65 years (OR 1.555; p < 0.001) and male sex (OR 1.162, p < 0.001). CONCLUSION: LAP-IHR remains a not frequent choice among surgeons in Spain, even when dealing with recurrent and bilateral hernias. The results suggest that the choice of LAP-IHR could depend on the surgeon's preference rather than on the indication appropriateness.

Long-term incisional hernia rate after single-incision laparoscopic cholecystectomy is significantly higher than that after standard three-port laparoscopy: a cohort study.

BACKGROUND: Single-incision laparoscopic cholecystectomy (SILC) is a feasible technique that provides comparable results to standard laparoscopic cholecystectomy (LC). However, despite the theoretical advantages of minor wound complications and cosmetic results, SILC usually requires a larger incision, which may increase the incidence of incisional hernias. This study evaluated SILC and standard multiport cholecystectomy with respect to perioperative outcomes, hospital stay, cosmetic results, and postoperative complications, including the 5-year incisional hernia rate. METHODS: A cohort study was performed with patients who underwent elective laparoscopic surgery for noncomplicated cholelithiasis at our hospital between July 2009 and June 2011. During the study period, there were 45 nonselected patients who underwent SILC, and these patients were compared with a control group of 140 patients who underwent LC using the standard three-trocar technique during the same period. Both patient groups were comparable in age, gender, BMI and ASA classification. RESULTS: The mean follow-up was 58.7 ± 10.9 (range 3-80) months. There were no differences between groups in terms of hospital stay, rate and severity of complications, wound infection, and patient cosmetic satisfaction. However, the operating time (57.8 versus 35.2 min) and long-term incisional hernia rate (13.3% versus 4.7%) were significantly higher in the SILC group. CONCLUSION: SILC is associated with a statistically significantly higher long-term incisional hernia rate at the umbilical port site than the standard multiport laparoscopic cholecystectomy. Our data show there was no relevant advantage regarding the postoperative course, hospital stay or cosmetic satisfaction. To date, widespread use of SILC cannot be recommended.

Long-term follow-up (at 5 years) of midline incisional hernia repairs using a primary closure and prosthetic onlay technique: recurrence and quality of life.

INTRODUCTION AND OBJECTIVES: The recurrence rate of incisional hernia (IH) repair is usually underestimated due to a lack of long-term follow-up. The objective of this study was to evaluate recurrence rate for patients operated on midline IH surgery, using a primary closure and prosthetic onlay technique, 5 years after the procedure. MATERIALS AND METHODS: From January 2009 to January 2011, all 92 patients operated on elective midline IH repair by primary closure and prosthetic onlay technique in a General Surgery Department were retrospectively included in the study. Exclusion criteria were absence of follow-up or death. Recurrence rate and quality of life were assessed. Demographic, surgical data and quality of life in patients with and without 5-year recurrence were compared. RESULTS: Mean follow-up was 64 months. Ultimately, 76 patients were included in the study, representing 82% of the selected patients during the study period (76/92), of whom 24 presented a recurrence (32%). Half (12) were diagnosed for recurrence more than 3 years after the surgery. Patients who developed a recurrence had more percentage of obesity (64 vs. 29%, p = 0.016), which denoted an odds ratio (OR) for recurrence of 4.4 (1.2-15.7; p = 0.01) and they punctuated lower in quality of life (6.0 ± 2.9 vs. 7.6 ± 2.6, p = 0.006). CONCLUSIONS: Recurrence rate on midline IH repair is still a concern (32% at 5 years). It is advisable to look for other strategies and more efficient surgical techniques for IH surgery, especially in obese patients.

Randomized clinical trial of mesh fixation with glue or sutures for Lichtenstein hernia repair.

BACKGROUND: Pain is the most likely reason for delay in resuming normal activities after groin hernia repair. The primary aim of this study was to determine whether the use of glue to fix the mesh instead of sutures reduced acute postoperative pain after inguinal hernia repair. Secondary objectives were to compare postoperative complications, chronic pain and early recurrence rates during 1-year follow-up. METHODS: Some 370 patients who underwent Lichtenstein hernia repair were randomized to receive either glue (Histoacryl®) or non-absorbable polypropylene sutures for fixation of lightweight polypropylene mesh. Postoperative complications, pain and recurrence were evaluated by an independent blinded observer. RESULTS: Postoperative pain at 8 h, 24 h, 7 days and 30 days was less when glue was used instead of sutures for all measures (P < 0·001). The operation was significantly quicker using glue (mean(s.d.) 35·3(8·7) min versus 39·9(11·1) min for sutures; P < 0·001). There were no significant differences between the groups in terms of postoperative complications, chronic pain and early recurrence at 1-year follow-up. CONCLUSION: Atraumatic mesh fixation with glue was quicker and resulted in less acute postoperative pain than sutures for Lichtenstein hernia repair.

Laparoscopic adrenalectomy in the elderly.

Laparoscopic adrenalectomy has recently been shown to be a safe and effective procedure for treating a variety of benign adrenal tumors. Advanced age, with its concomitant comorbid conditions, has been believed to be associated with more postoperative complications in laparoscopic procedures. The purpose of this study was to evaluate the outcome of laparoscopic adrenalectomy in patients age 65 and older. From June 1992 to February 1998, 14 patients (4 men and 10 women) with a mean age of 69 years underwent 17 laparoscopic adrenalectomies. In 12 procedures, a transperitoneal lateral decubitus flank approach was used. The lesion was a nonfunctioning adenoma in three patients, aldosterone adenoma in four, Cushing's syndrome in four, and pheochromocytoma in one. A retroperitoneal lateral decubitus approach was used in five procedures. The lesion was a nonfunctioning adenoma in one patient, aldosterone adenoma in one, Cushing's adenoma in one, and pheochromocytoma in two. Seventy-eight percent of these patients had comorbid conditions, including hypertension, diabetes, chronic obstructive airway disease, coronary artery disease, and cardiac dysrhythmia. The preoperative physical status was as ASA Class II in 11 patients and ASA III in 3. Two of the 17 laparoscopies were converted to open surgery (11%), in one because of difficulties in dissecting extraperitoneally a mass >8 cm, and in the other because of difficulties in localization of a 3-cm mass. The median surgical time was 95 +/- 33 minutes. The mean analgesia requirements were 3 doses of (range 2-7) ketorolac. There were no deaths. Postoperative morbidity consisted of pulmonary atelectasis in one patient and urinary tract infection in two patients. The median hospital stay was 3 days (range 2-4 days). We conclude that laparoscopic adrenalectomy in the elderly population is safe and offers low morbidity, fast recovery, and a short hospital stay. Age alone should not be a contraindication to treating adrenal tumors laparoscopically.

Mirizzi's syndrome. Diagnostic and therapeutic controversies in the laparoscopic era.

BACKGROUND: Mirizzi's syndrome (MS) is an unusual cause of obstructive jaundice. It can mimic bile duct cancer, and the role of laparoscopic surgery is not well defined. The aim of this paper is to report five cases and describe the pitfalls encountered in its diagnosis and treatment with a laparoscopic approach. METHODS: From January 1992 to January 1996, five cases of MS out of 560 patients with gallstones prospectively treated and recorded were found (0.9%). RESULTS: There were two men and three women, (mean age: 54 years [30-93]). In one case diagnosis of bile duct carcinoma was established but surgery revealed MS. Four cases were approached by laparoscopy, but all of them were converted: in two, due to a distorted anatomy, in a third due in the difficulty of visualizing the distal end of the bile duct, and in the last case due to the impossibility of retrieving the stones. All were treated with a cholecochorrhaphy over a T tube, except one, in which a hepaticojejunostomy was performed. Morbidity and mortality were nil, and they remain asymptomatic after a mean follow-up of 19 months (3-36). CONCLUSIONS: MS constitutes an important laparoscopic challenge, both to clearance of duct stones and to the proper reconstruction of the biliary duct. A prudent policy is to perform a dissection trial and convert if local conditions are not clear for an experienced laparoscopic surgeon.
