Single incision laparoscopic surgery using conventional laparoscopic instruments versus two-port laparoscopic surgery for adnexal lesions

Effect of Two-Port Laparoscopic Surgery on Pregnancy Outcomes of Patients with Concurrent Adnexal Masses

Adnexal masses are common in pregnancy, with 2–10% of pregnancies presenting with an ovarian mass and approximately 1–6% of these masses being malignant. For suspected malignancy or masses with symptoms, surgery must be performed as early as possible. We retrospectively investigated the effect of two-port laparoscopic surgery on the outcomes of patients with concurrent adnexal masses between 2012 and 2019 (including large mucinous tumor, large teratoma, serous borderline tumor, and heterotopic pregnancy). Laparoscopic right partial oophorectomy was performed for a 27 cm ovarian mucinous tumor at a gestational age (GA) of 21 weeks, laparoscopic right oophorocystectomy for an 18 cm teratoma at a GA of 10 weeks, and laparoscopic left salpingo-oophorectomy for a 7 cm serous borderline tumor at a GA of 7 weeks after ultrasonographic confirmation of an intrauterine gestational sac with a fetal heartbeat. Laparoscopic excision of a tubal pregnancy was performed in a heterotopic pregnancy at a GA of 12 weeks with massive internal bleeding. Laparoscopic surgery is easier and safe to perform during early pregnancy because a smaller uterus allows for superior visualization. All of these patients had optimal postoperative recovery and normal spontaneous delivery at term. We discussed several aspects of treatment and delivery, namely treatment option (expectant management or surgery), surgery timing (early or advanced pregnancy), surgery type (laparoscopy or laparotomy), and delivery route (normal spontaneous delivery or cesarean section), in patients with concurrent adnexal tumors and their effects on pregnancy outcomes.

Paratubal Cystectomy in a Pregnant Woman Using the Single-Incision Laparoscopic Surgery (SILS) Technique

Introduction

The proliferation of prenatal ultrasound has enhanced the detection of adnexal masses during pregnancy. The presentation necessitates a clear approach to investigation and treatment that balances both maternal and fetal risk. Laparoscopy is a safe approach to surgical management in the pregnant patient, and SILS may contribute to minimising perioperative complications. Case Presentation. We present the case of a 21-year-old female in her second trimester of pregnancy presenting with a large 20 cm right adnexal cyst. We proceeded with laparoscopic cystectomy via the SILS technique. There were no intraoperative complications, and she recovered well postoperatively.

Conclusion

Laparoscopic resection of adnexal lesions is safe during pregnancy and should be favoured over the open approach. SILS minimises incision sites and has potential for reduction in perioperative morbidity.

Single-incision laparoscopic splenectomy in children with massive splenomegaly: A prospective, monocentric pilot study

BACKGROUND

Single-incision laparoscopic splenectomy (SILS) remains a challenging procedure because of the technical difficulty. In this prospective study, we aimed to evaluate the efficacy and safety of SILS in children with massive splenomegaly.

METHODS

Pediatric patients with massive splenomegaly were recruited for SILS in a university-affiliated hospital. The data on patient demographics, clinical features, operative variables, and perioperative outcomes were collected prospectively and analyzed. According to the different surgical instruments, the patients were randomly assigned into two groups: the SILS with straight surgical instrument (SILS-S) group and the SILS with curved surgical instrument (SILS-C) group. A two-group comparative analysis was conducted using perioperative data from the different surgical instrumentation systems.

RESULTS

A total of 120 patients were included, of which 103 patients (success group, 85.83%) had complete SILS, the other 17 (failure group, 14.17%) patients were converted to open (n = 4, 3.33%) or multi-incision laparoscopic surgery (n = 13, 10.83%). The major cause for surgical failure is uncontrollable bleeding (n = 14, 82.35%), and age, height, and weight were the risk factors for failure of SILS, but none of the parameters were independent risk factors. The blood loss in the success group was less than that in the failure group, but no significant differences in other operative and outcome indicators. For SILS, the mean (±SD) operative time was 188 (±48.70) minutes, the median intraoperative blood loss (min, max) was 20 (5, 290) ml, the mean (±SD) time of first anal exhaust was 23.9 (±7.73) hours, and the mean (±SD) postoperative hospital stay was 4.72 (±1.03) days. The median pain score was 3 on 1 day, and 1 on 3 days after the operation. Postoperative complications were identified in 8 (7.77%) cases. However, there were no peri-operative deaths in this series. The SILS-C group had a significantly shorter operation time than the SILS-S group (mean ± SD, 172 ± 44.21 vs. 205 ± 47.90 min). There were no significant differences between the two groups in other perioperative data (P < 0.05).

CONCLUSION

SILS is a safe and feasible treatment in pediatric patients with massive splenomegaly, and curved surgical instrumentation has contributed to developing surgical manipulation.
